Improving the life-course development of socially disadvantaged mothers: a randomized trial of nurse home visitation

Burden of Mental Disorders and Suicide Attributable to Childhood Maltreatment

Importance

The proportion of mental disorders and burden causally attributable to childhood maltreatment is unknown.

Objective

To determine the contribution of child maltreatment to mental health conditions in Australia, accounting for genetic and environmental confounding.

Design, Setting, and Participants

This meta-analysis involved an epidemiological assessment accounting for genetic and environmental confounding between maltreatment and mental health and 3 cross-sectional national surveys: the Australian Child Maltreatment Study (ACMS) 2023, National Study of Mental Health and Well-being 2020-2022, and Australian Burden of Disease Study 2023. Causal estimates were derived on the association between childhood maltreatment and mental health conditions from a meta-analysis of quasi-experimental studies. This was combined with the prevalence of maltreatment from the ACMS to calculate the population attributable fraction (PAF). The PAF was applied to the number and burden of mental health conditions in Australia, sourced from 2 population-based, nationally representative surveys of Australians aged 16 to 85 years, to generate the number and associated burden of mental disorders attributable to child maltreatment.

Exposure

Physical abuse, sexual abuse, emotional abuse, or neglect prior to age 18 years.

Main Outcomes and Measures

Proportion and number of cases, years of life lost, years lived with disability, and disability-adjusted life-years of mental health conditions (anxiety, depression, harmful alcohol and drug use, self-harm, and suicide attempt) attributable to childhood maltreatment.

Results

Meta-analytic estimates were generated from 34 studies and 54 646 participants and applied to prevalence estimates of childhood maltreatment generated from 8503 Australians. Childhood maltreatment accounted for a substantial proportion of mental health conditions, ranging from 21% (95% CI, 13%-28%) for depression to 41% (95% CI, 27%-54%) of suicide attempts. More than 1.8 million cases of depressive, anxiety, and substance use disorders could be prevented if childhood maltreatment was eradicated. Maltreatment accounted for 66 143 years of life lost (95% CI, 43 313-87 314), primarily through suicide, and 184 636 disability-adjusted life-years (95% CI, 109 321-252 887).

Conclusions and Relevance

This study provides the first estimates of the causal contribution of child maltreatment to mental health in Australia. Results highlight the urgency of preventing child maltreatment to reduce the population prevalence and burden of mental disorders.

Evaluating the real-world implementation of the Family Nurse Partnership in England: a data linkage study

Background/objectives

The Family Nurse Partnership is an intensive home visiting programme for adolescent mothers. We aimed to evaluate the effectiveness of the Family Nurse Partnership on outcomes up to age 7 using national administrative data.

Design

We created a linked cohort of all mothers aged 13-19 using data from health, educational and children's social care and defined mothers enrolled in the Family Nurse Partnership or not using Family Nurse Partnership system data. Propensity scores were used to create matched groups for analysis.

Setting

One hundred and thirty-six local authorities in England with active Family Nurse Partnership sites between 2010 and 2017.

Participants

Mothers aged 13-19 at last menstrual period with live births between April 2010 and March 2019, living in a Family Nurse Partnership catchment area and their firstborn child(ren).

Interventions

The Family Nurse Partnership includes up to 64 home visits by a family nurse from early pregnancy until the child's second birthday and is combined with usual health and social care. Controls received usual health and social care.

Main outcome measures

Indicators of child maltreatment (hospital admissions for injury/maltreatment, referral to social care services); child health and development (hospital utilisation and education) outcomes and maternal hospital utilisation and educational outcomes up to 7 years following birth.

Data sources

Family Nurse Partnership Information System, Hospital Episode Statistics, National Pupil Database.

Results

Of 110,520 eligible mothers, 25,680 (23.2%) were enrolled in the Family Nurse Partnership. Enrolment rates varied across 122 sites (range: 11-68%). Areas with more eligible mothers had lower enrolment rates. Enrolment was higher among mothers aged 13-15 (52%), than 18-19 year-olds (21%). Indicators of child maltreatment: we found no evidence of an association between the Family Nurse Partnership and indicators of child maltreatment, except for an increased rate of unplanned admissions for maltreatment/injury-related diagnoses up to age 2 for children born to Family Nurse Partnership mothers (6.6% vs. 5.7%, relative risk 1.15; 95% confidence interval 1.07 to 1.24). Child health and developmental outcomes: there was weak evidence that children born to Family Nurse Partnership mothers were more likely to achieve a Good Level of Development at age 5 (57.5% vs. 55.4%, relative risk 1.05; 95% confidence interval 1.00 to 1.09). Maternal outcomes: There was some evidence that Family Nurse Partnership mothers were less likely to have a subsequent delivery within 18 months of the index birth (8.4% vs. 9.3%, relative risk 0.92; 95% confidence interval 0.88 to 0.97). Younger and more vulnerable mothers received higher numbers of visits and were more likely to achieve fidelity targets. Meeting the fidelity targets was associated with some outcomes.

Limitations

Bias by indication and variation in the intervention and usual care over time and between areas may have limited our ability to detect effects. Multiple testing may have led to spurious, significant results.

Conclusions

This study supports findings from evaluations of the Family Nurse Partnership showing no evidence of benefit for maltreatment outcomes measured in administrative data. Amongst all the outcomes measured, we found weak evidence that the Family Nurse Partnership was associated with improvements in child development at school entry, a reduction in rapid repeat pregnancies and evidence of increased healthcare-seeking in the mother and child.

Future work

Future evaluations should capture better measures of Family Nurse Partnership interventions and usual care, more information on maternal risk factors and additional outcomes relating to maternal well-being.

Effect of early childhood development interventions delivered by healthcare providers to improve cognitive outcomes in children at 0-36 months: a systematic review and meta-analysis

OBJECTIVE

To determine the effect of early childhood development interventions delivered by healthcare providers (HCP-ECD) on child cognition and maternal mental health.

DESIGN

Systematic review, meta-analysis.

SETTING

Healthcare setting or home.

PARTICIPANTS

Infants under 1 month of age.

INTERVENTIONS

HCP-ECD interventions that supported responsive caregiving, early learning and motor stimulation. MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Health Technology Assessment Database, Database of Abstracts of Reviews of Effects and Cochrane Database of Systematic Reviews were searched until 15 November 2021. Studies reporting prespecified outcomes were pooled using standard meta-analytical methods.

MAIN OUTCOME MEASURES

Cognitive development in children at 0-36 months.

RESULTS

Forty-two randomised controlled trials with 15 557 infants were included in the narrative synthesis. Twenty-seven trials were included in the meta-analyses. Pooled data from 13 trials suggest that HCP-ECD interventions may improve cognitive outcomes in children between 0 and 36 months (Bayley Scales of Infant Development version IIII (BSID-III) mean difference (MD) 2.65; 95% CI 0.61 to 4.70; 2482 participants; low certainty of evidence). Pooled data from nine trials suggest improvements in motor development (BSID-III MD 4.01; 95% CI 1.54 to 6.48; 1437 participants; low certainty of evidence). There was no evidence of improvement in maternal mental health (standardised MD -0.13; 95% CI -0.28 to 0.03; 2806 participants; 11 trials; low certainty of evidence).

CONCLUSIONS

We report promising evidence, particularly for cognitive and motor outcomes, of the effect of HCP-ECD interventions. However, effect sizes were small, and the certainty of evidence ranged from very low to moderate. Additional high-quality research is required.

The Co-Occurrence of Child Maltreatment and Intimate Partner Violence in Families: Effects on Children's Externalizing Behavior Problems

Children exposed to maltreatment are at risk of experiencing intimate partner violence (IPV) and behavioral problems. This study examined different forms of family violence that co-occur and their relationship to children's externalizing behaviors across developmental stages (early childhood, middle childhood, adolescence). Longitudinal data (N = 1,987) at baseline and 18 months and 36 months post-baseline from the NSCAW II were used. Mixture modeling was employed in which latent class models estimated subgroups of children who experienced co-occurring forms of family violence; regression models estimated which subgroups of children were at risk of externalizing behaviors. Three latent classes were identified across developmental stages: high family violence, low family violence, and child physical abuse and psychological aggression. For children in early childhood, a fourth class was identified: partner and child physical abuse and child psychological aggression. Results from regression models revealed differences in externalizing scores by class membership across developmental age groups and over time. That distinct classes of child maltreatment and IPV co-occur and differentially impact children's behavior suggests a need for strong prevention and intervention responses to address children's dual maltreatment and IPV exposure.

Maternal and Child Mortality: Analysis of Nurse Home Visiting in 3 RCTs

INTRODUCTION

The impact of intensive prenatal and infant/toddler nurse home visiting on low-income mothers' and children's survival was examined in 3 RCTs following participants over 2-decade periods after trial registration during pregnancy (data gathered between 1978 and 2015 and analyzed between 2016 and 2020).

METHODS

All-cause and external-cause maternal mortality and preventable-cause child mortality were examined using National Death Index data. Survival rates were calculated for all the 1,138 mothers randomized and 1,076 live-born children in the second RCT (conducted in Memphis, TN) and for all the 1,135 mothers randomized and 1,087 live-born children in the first and third RCTs combined (conducted in Elmira, NY and Denver, CO).

RESULTS

There were no significant nurse home visiting-control differences in maternal mortality in Memphis or Elmira and Denver. Posthoc analysis, combining all 3 trials, suggested a reduction in external-cause maternal mortality among nurse-visited mothers (p=0.054). There was a marginally significant nurse home visiting-control difference in preventable-cause child mortality (p=0.09) in Memphis.

CONCLUSIONS

These results support examining maternal and child mortality in additional nurse home visiting trials with larger samples living in disadvantaged contexts. Intensive prenatal and infant/toddler home visiting by nurses for mothers and children living in poverty may decrease premature death.

Racial/Ethnic Differences in Prenatal and Postnatal Counseling About Maternal and Infant Health-Promoting Practices Among Teen Mothers

STUDY OBJECTIVE

Disparities in perinatal counseling among all pregnant women exist, yet teen data are lacking. We evaluated racial/ethnic differences in (1) prenatal and (2) postnatal counseling of teen mothers.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cross-sectional study included Pregnancy Risk Assessment Monitoring System data from 2012-2016 and included mothers 19 years of age and younger.

INTERVENTIONS AND MAIN OUTCOME MEASURES

Counseling measures included tobacco, alcohol and illicit drugs, weight gain, HIV testing, influenza vaccination, breastfeeding, infant safe sleep, postpartum depression, and contraception. Bivariate associations of maternal/infant characteristics and counseling were estimated using χ² tests. Multivariable logistic regression was used to assess the independent relationship between race/ethnicity and counseling.

RESULTS

A weighted sample of 544,930 teen mothers was analyzed. Compared with non-Hispanic white (NHW) teens, non-Hispanic black teens were more likely to receive counseling on tobacco (adjusted odds ratio [aOR], 1.4; 95% confidence interval [CI], 1.10-1.77), alcohol (aOR, 1.77; 95% CI, 1.28-2.46), illicit drugs (aOR, 1.79; 95% CI, 1.33-2.41), and HIV testing (aOR, 1.62; 95% CI, 1.26-2.09). Compared with NHW teens, Hispanic teens were less likely to receive tobacco counseling (aOR, 0.78; 95% CI, 0.64-0.97) and more likely to receive influenza vaccine counseling (aOR, 1.44; 95% CI, 1.18-1.76). No difference was found in receipt of postnatal counseling.

CONCLUSION

Racial/ethnic differences in receipt of perinatal counseling exist, with non-Hispanic black teens being more likely to receive counseling on substance use and HIV testing and Hispanic teens being more likely to receive influenza vaccine recommendations compared with NHW teens. Ongoing investigation is needed to understand drivers of these differences.

Protocol for a randomized controlled trial evaluating the impact of the Nurse-Family Partnership's home visiting program in South Carolina on maternal and child health outcomes

Background

Policy-makers are increasingly seeking rigorous evidence on the impact of programs that go beyond typical health care settings to improve outcomes for low-income families during the critical period around the transition to parenthood and through early childhood.

Methods

This study is a randomized controlled trial evaluating the impact of the Nurse-Family Partnership’s expansion in South Carolina. The scientific trial was made possible by a “Pay for Success” program embedded within a 1915(b) Waiver from Medicaid secured by the South Carolina Department of Health and Human Services. This protocol describes study procedures and defines primary and secondary health-related outcomes that can be observed during the intervention period (including pregnancy through the child’s first 2 years of life). Primary study outcomes include (1) a composite indicator for adverse birth outcomes including being born small for gestational age, low birth weight (less than 2500 g), preterm birth (less than 37 weeks’ gestation), or perinatal mortality (fetal death at or after 20 weeks of gestation or mortality in the first 7 days of life), (2) a composite outcome indicating health care utilization or mortality associated with major injury or concern for abuse or neglect occurring during the child’s first 24 months of life, and (3) an indicator for an inter-birth interval of < 21 months. Secondary outcomes are defined similarly in three domains: (1) improving pregnancy and birth outcomes, (2) improving child health and development, and (3) altering the maternal life course through changes in family planning.

Discussion

Evidence from this trial on the impact of home visiting services delivered at scale as part of a Medicaid benefit can provide policy-makers and stakeholders with crucial information about the effectiveness of home visiting programs in improving health and well-being for low-income mothers and children and about novel financing mechanisms for cross-silo interventions.

Trial registration

The trial was registered prospectively on the American Economic Association Trial Registry (the primary registry for academic economists doing policy trials) on 16 February 2016 (AEARCTR-0001039). ClinicalTrials.gov NCT03360539. Registered on 28 November 2017.

Changing self-control: Promising efforts and a way forward

Researchers have long known that self-control, or impulse control, is important for a variety of life outcomes, including health, education, and behavior. In criminology, the most popular perspective on self-control argues that it is a multidimensional trait that is relatively stable after about age 8. Some work, however, has shown that in fact, self-control may not be as stable as originally thought. This article examines the evidence on interventions seeking to enhance self-control and subsequently to reduce delinquent or criminal behavior. The evidence is growing but still in need of development. Implications for future research and practice are discussed in the conclusion.

Evaluation of the effectiveness of the Family Nurse Partnership home visiting programme in first time young mothers in Scotland: a protocol for a natural experiment

Introduction

Individual, social and economic circumstances faced by young mothers (19 years or under) can challenge a successful start in life for their children. Intervening early might enhance life chances for both mother and child. The Family Nurse Partnership (FNP) is an intensive nurse-led home visiting programme developed in the US which aims to improve prenatal health behaviours, birth outcomes, child development and health outcomes, and maternal life course. Establishing evidence of effectiveness beyond the original US setting is important to understand where further adaptation is required within a country specific context.

Objective

This study will form one strand of the Scottish Government’s plan to evaluate the effectiveness of FNP as compared to usual care for mothers and their children in Scotland and will focus only on outcomes that can be identified using routine administrative data systems.

Methods

This study is a natural experiment with a case-cohort design using linked anonymised routine health, educational and social care data. Cases will be women enrolled as FNP Clients in ten NHS Health Boards in Scotland and Controls will be women who met FNP eligibility criteria but were pregnant at a time when the programme was not recruiting. Outcomes are mapped to the Scottish FNP logic model. All comparative analyses will be pre-specified, conducted on an intention to treat basis and will use multilevel regression models to compare outcomes between groups.

Discussion

The study protocol is based upon the specification of FNP commissioned by the Scottish Government. This study design is novel for the evaluation of the FNP/NFP programmes which are primarily evaluated with an RCT. Outcomes included within the study have been selected on the basis that they are outcomes FNP aims to influence and where there is routine data available to assess the outcome

Education and employment outcomes in clients of the Nurse-Family Partnership

OBJECTIVES

Nurse-Family Partnership (NFP) is an evidence-based home visitation program designed for low-income, first-time mothers to support pregnancy, child development, and maternal self-sufficiency. This study examined educational and employment outcomes among NFP clients compared to a reference sample.

DESIGN

Entropy balancing and a difference-in-difference design were used to compare the two samples of women from 2007 to 2016.

SAMPLE

There were 127,427 women in the NFP sample, and 787 women in the reference cohort.

MEASUREMENTS

Educational outcomes included high school completion and employment outcomes consisted of employment status.

RESULTS

Across a one-year interval, NFP mothers with less than a high school diploma or general education diploma (GED) at baseline showed a 9.5 percentage point increase in diploma or GED attainment compared to the reference mothers [95% CI: 0.015-0.180]. Similarly, mothers enrolled in NFP who were not employed at baseline showed a 7.8 percentage point increase in employment compared to the reference mothers [95% CI: 0.003-0.150].

CONCLUSIONS

The findings in this study show positive results for NFP mothers attaining high school completion and employment compared to mothers in the reference group. Such findings are of importance with regard to progression toward economic self-sufficiency and corresponding reduction of health disparities.

Nurse home visitation with vulnerable families in rural areas: A qualitative case file review

OBJECTIVE

Nurse home visiting may address challenges and resource disparities that threaten maternal and infant well-being in rural areas, but little is known about United States' program implementation. This qualitative study explored how family and community characteristics affected rural nurse home visiting.

SAMPLE

The sample for content analysis included families beginning services in 2010-2011 living in the rural counties with the highest caseloads (433 families).

DESIGN

Electronic nurse home visiting case files from three rural counties were analyzed using a content analysis approach. The partner agency provided input on key constructs of interest but independent coding was also done to capture additional themes. Quantitative county level data and comments from member checking informed interpretation. Member checking included individual nurses serving the selected counties (n = 3) and input from an agency level supervisory meeting for validation.

RESULTS

Concerns of families served (e.g., mental health) may not be unique to rural areas, but challenges to accessing resources and constellation of needs were. Nurses adapted engagement and service strategies to meet these needs.

CONCLUSION

Agencies serving rural areas should allocate resources and adapt training to support nurses based on unique community profiles. More research on rural nurse home visiting practice and outcomes is needed.

Prenatal and Infancy Nurse Home Visiting Effects on Mothers: 18-Year Follow-up of a Randomized Trial

BACKGROUND

Prenatal and infancy home-visiting by nurses is promoted as a means of improving maternal life-course, but evidence of long-term effects is limited. We hypothesized that nurse-visitation would lead to long-term reductions in public-benefit costs, maternal substance abuse and depression, and that cost-savings would be greater for mothers with initially higher psychological resources.

METHODS

We conducted an 18-year follow-up of 618 out of 742 low-income, primarily African-American mothers with no previous live births enrolled in an randomized clinical trial of prenatal and infancy home visiting by nurses. We compared nurse-visited and control-group women for public-benefit costs, rates of substance abuse and depression, and examined possible mediators of intervention effects.

RESULTS

Nurse-visited women, compared with controls, incurred $17 310 less in public benefit costs (P = .03), an effect more pronounced for women with higher psychological resources ($28 847, P = .01). These savings compare with program costs of $12 578. There were no program effects on substance abuseor depression. Nurse-visited women were more likely to be married from child age 2 through 18 (19.2% vs 14.8%, P = .04), and those with higher psychological resources had 4.64 fewer cumulative years rearing subsequent children after the birth of the first child (P = .03). Pregnancy planning was a significant mediator of program effects on public benefit costs.

CONCLUSIONS

Through child age 18, the program reduced public-benefit costs, an effect more pronounced for mothers with higher psychological resources and mediated by subsequent pregnancy planning. There were no effects on maternal substance abuse and depression.

Effectiveness of a 2-year post-natal nurse home-visiting programme when children are aged 5 years: Results from a natural experiment

AIM

To evaluate the effect of a 2-year post-natal nurse home visiting (NHV) programme delivered in routine clinical practice to socially disadvantaged mothers on children's development at 5 years.

METHODS

The study was a natural experiment resulting from progressive rollout of NHV (2008-2012). Children of three groups of mothers, all eligible for NHV, were compared: (i) mothers receiving NHV in a metropolitan region (n = 197); (ii) mothers in a rural region prior to NHV being available (n = 94); and (iii) mothers receiving NHV in the rural region after it became available (n = 84). Outcomes were evaluated using the Child Behaviour Checklist, Child-Parent Relationships Scale, Behaviour Inventory of Executive Functioning and Australian Early Development Index.

RESULTS

Analyses were conducted using augmented inverse probability weighting accounting for differences in the groups' baseline characteristics. While some differences were observed in the range of 8-12% between the intervention and comparison groups (albeit with wide confidence intervals, e.g. 31% less likely to 4% more likely to be experiencing poor outcomes). For the majority of outcomes, however, there were no differences observed between the intervention and comparison groups.

CONCLUSIONS

Post-natal NHV provided as a part of routine service delivery did not improve children's outcomes at 5 years. It may be that in the Australian context a NHV intervention, as offered in this study, does not provide additional benefits over standard care.

Implementation of the Family Nurse Partnership programme in England: experiences of key health professionals explored through trial parallel process evaluation

BACKGROUND

The Family Nurse Partnership (FNP) programme was introduced to support young first-time mothers. A randomised trial found FNP added little short-term benefit compared to usual care. The study included a comprehensive parallel process evaluation, including focus groups, conducted to aid understanding of the introduction of the programme into a new service and social context. The aim of the focus groups was to investigate views of key health professionals towards the integration and delivery of FNP programme in England.

METHODS

Focus groups were conducted separately with Family Nurses, Health Visitors and Midwives at trial sites during 2011-2012. Transcripts from audio-recordings were analysed thematically.

RESULTS

A total of 122 professionals participated in one of 19 focus groups. Family Nurses were confident in the effectiveness of FNP, although they experienced practical difficulties meeting programme fidelity targets and considered that programme goals did not sufficiently reflect client or community priorities. Health Visitors and Midwives regarded FNP as well-resourced and beneficial to clients, describing their own services as undervalued and struggling. They wished to work closely with Family Nurses, but felt excluded from doing so by practical barriers and programme protection.

CONCLUSION

FNP was described as well-resourced and delivered by highly motivated and well supported Family Nurses. FNP eligibility, content and outcomes conflicted with individual client and community priorities. These factors may have restricted the potential effectiveness of a programme developed and previously tested in a different social milieu. Building Blocks ISRCTN23019866 Registered 20/04/2009.

Support during pregnancy for women at increased risk of low birthweight babies

BACKGROUND

Studies consistently show a relationship between social disadvantage and low birthweight. Many countries have programmes offering special assistance to women thought to be at risk for giving birth to a low birthweight infant. These programmes, collectively referred to in this review as additional social support, may include emotional support, which gives a person a feeling of being loved and cared for, tangible/instrumental support, in the form of direct assistance/home visits, and informational support, through the provision of advice, guidance and counselling. The programmes may be delivered by multidisciplinary teams of health professionals, specially trained lay workers, or a combination of lay and professional workers. This is an update of a review first published in 2003 and updated in 2010.

OBJECTIVES

The primary objective was to assess the effects of programmes offering additional social support (emotional, instrumental/tangible and informational) compared with routine care, for pregnant women believed to be at high risk for giving birth to babies that are either preterm (less than 37 weeks' gestation) or weigh less than 2500 g, or both, at birth. Secondary objectives were to determine whether the effectiveness of support was mediated by timing of onset (early versus later in pregnancy) or type of provider (healthcare professional or lay person).

SEARCH METHODS

For this update, we searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) on 5 February 2018, and reference lists of retrieved studies.

SELECTION CRITERIA

Randomised trials of additional social support during at-risk pregnancy by either a professional (social worker, midwife, or nurse) or specially trained lay person, compared to routine care. We defined additional social support as some form of emotional support (e.g. caring, empathy, trust), tangible/instrumental support (e.g. transportation to clinic appointments, home visits complemented with phone calls, help with household responsibilities) or informational support (advice and counselling about nutrition, rest, stress management, use of alcohol/recreational drugs).

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed studies for inclusion and risk of bias, extracted data and checked them for accuracy. We assessed the quality of the evidence using the GRADE approach.

MAIN RESULTS

This updated review includes a total of 25 studies, with outcome data for 11,246 mothers and babies enrolled in 21 studies. We assessed the overall risk of bias of included studies to be low or unclear, mainly because of limited reporting or uncertainty in how randomisation was generated or concealed (which led us to downgrade the quality of most outcomes to moderate), and the impracticability of blinding participants.When compared with routine care, programmes offering additional social support for at-risk pregnant women may slightly reduce the number of babies born with a birthweight less than 2500 g from 127 per 1000 to 120 per 1000 (risk ratio (RR) 0.94, 95% confidence interval (CI) 0.86 to 1.04; 16 studies, n = 11,770; moderate-quality evidence), and the number of babies born with a gestational age less than 37 weeks at birth from 128 per 1000 to 117 per 1000 (RR 0.92, 95% CI 0.84 to 1.01, 14 studies, n = 12,282; moderate-quality evidence), though the confidence intervals for the pooled effect for both of these outcomes just crossed the line of no effect, suggesting any effect is not large. There may be little or no difference between interventions for stillbirth/neonatal death (RR 1.11, 95% CI 0.88 to 1.41; 15 studies, n = 12,091; low-quality evidence). Secondary outcomes of moderate quality suggested that there is probably a reduction in caesarean section (from 215 per 1000 to 194 per 1000; RR 0.90, 95% CI 0.83 to 0.97; 15 studies, n = 9550), a reduction in the number of antenatal hospital admissions per participant (RR 0.78, 95% CI 0.68 to 0.91; 4 studies; n = 787), and a reduction in the mean number of hospitalisation episodes (mean difference -0.05, 95% CI -0.06 to -0.04; 1 study, n = 1525) in the social support group, compared to the controls.Postnatal depression and women's satisfaction were reported in different ways in the studies that considered these outcomes and so we could not include data in a meta-analysis. In one study postnatal depression appeared to be slightly lower in the support group in women who screened positively on the Edinbugh Postnatal Depression Scale at eight to 12 weeks postnatally (RR 0.74, 95% CI 0.55 to 1.01; 1 study, n = 1008; moderate-quality evidence). In another study, again postnatal depression appeared to be slightly lower in the support group and this was a self-report measure assessed at six weeks postnatally (RR 0.85, 95% CI 0.69 to 1.05; 1 study, n = 458; low-quality evidence). A higher proportion of women in one study reported that their prenatal care was very helpful in the supported group (RR 1.17, 95% CI 1.05 to 1.30; 1 study, n = 223; moderate-quality evidence), although in another study results were similar. Another study assessed satisfaction with prenatal care as being "not good" in 51 of 945 in the additional support group, compared with 45 of 942 in the usual care group.No studies considered long-term morbidity for the infant. No single outcome was reported in all studies. Subgroup analysis demonstrated consistency of effect when the support was provided by a healthcare professional or a trained lay worker.The descriptions of the additional social support were generally consistent across all studies and included emotional support, tangible support such as home visits, and informational support.

AUTHORS' CONCLUSIONS

Pregnant women need the support of caring family members, friends, and health professionals. While programmes that offer additional social support during pregnancy are unlikely to have a large impact on the proportion of low birthweight babies or birth before 37 weeks' gestation and no impact on stillbirth or neonatal death, they may be helpful in reducing the likelihood of caesarean birth and antenatal hospital admission.

Effects of early childhood intervention on fertility and maternal employment: Evidence from a randomized controlled trial

This paper presents the results of a randomized study of a home visiting program implemented in Germany for low-income, first-time mothers. Besides improving child health and development, a major goal of the program is to improve the participants' economic self-sufficiency and family planning. I use administrative data from the German social security system and detailed telephone surveys to examine the effects of the intervention on maternal employment, welfare benefits, household composition, well-being, and fertility behavior. The study reveals that the intervention decreased maternal employment by 9.3 percentage points and increased subsequent births by 6.4 percentage points, in part through a reduction in abortions.

Conditions and Dynamics That Impact Maternal Health Literacy among High Risk Prenatal-Interconceptional Women

The purpose of the study was to describe conditions and dynamics in the lives of high-risk, low-income, Southern United States prenatal-interconceptional women (n = 37) in a home visiting program that promoted maternal health literacy progression. In the Life Course Health Development (LCHD) Model, conditions were risk and protective factors that impacted health. Dynamics drove the complex, epigenetic relationships between risk and protective factors. Maternal health literacy promotion helped participants address conditions and dynamics to create positive life changes. This research was a retrospective, mixed methods study of women's service records documenting care from prenatal admission to 24 months post-delivery. The Life Skills Progression Instrument (LSP) was scored to measure maternal health literacy progression. Ethnographic content analysis of visit notes triangulated with quantitative data enabled specificity of critical data elements. Subsequently, a complementary focus group was conducted with the Registered Nurse Case Managers (RNCM). Severe social conditions included devastating poverty, low educational achievement, transient housing, unstable relationships, incarceration, lack of continuous health insurance, and shortage of health care providers. Dynamics included severe psycho-social stressors, domestic violence, lack of employment, low income, low self-esteem and self-expectations, and social/family restraints upon women's intended positive changes. An important protective factor was the consistent, stable, evidence-informed relationship with the RNCM. Findings from the focus group discussion supported content analysis results.

The Promise of Prevention Science for Addressing Intergenerational Poverty

This paper reviews research suggesting that the prevention of intergenerational poverty will be enhanced if we add evidence-based family and school prevention programs to existing efforts to reduce poverty in order to address the adverse social environments that often accompany poverty. Government policies such as the Earned Income Tax Credit can reduce family poverty, but simply improving the economic stability of the family will not necessarily prevent the development of child and adolescent problems such as academic failure, antisocial behavior, drug abuse, and depression, all of which can undermine future economic wellbeing. We briefly review the evidence linking family poverty to adverse social environments, which can have deleterious effects on children's psychological, behavioral, neurological, and physical development. We then document the value of evidence-based family- and school-based prevention programs in effectively addressing these behavioral, emotional, cognitive, and neurophysiological factors that can put children at risk for continued poverty in adulthood. We also describe three family-based prevention programs that have been found to have a direct effect on families' future economic wellbeing. The evidence indicates that widely disseminating effective and efficient family- and school-based prevention programs can help to address both poverty itself and the effects of adverse social environments, making future poverty less likely. We conclude with specific recommendations for federal and state policymakers, researchers, and practitioners.

No Improvements in Postnatal Dietary Outcomes Were Observed in a Two-Arm, Randomized, Controlled, Comparative Impact Trial among Rural, Southern, African-American Women

BACKGROUND

Suboptimal diet quality, prevalent among postpartum women, is troubling for mothers and their children because positive relationships between maternal and child diet quality exist.

OBJECTIVE

The primary objective was to determine whether postnatal diet quality scores of participants in the two treatment arms differed or changed over time.

DESIGN

Delta Healthy Sprouts was a two-arm, randomized, controlled, comparative impact trial.

PARTICIPANTS AND SETTING

Pregnant women at least 18 years of age, less than 19 weeks pregnant, and residing in three Mississippi counties were recruited between March 2013 and December 2014. Postnatal data was collected from 54 participants between September 2013 and May 2016. The postnatal attrition rates were 17% and 13% for the control and experimental arms.

INTERVENTION

The control arm received the Parents as Teachers curriculum, and the experimental arm received a nutrition- and physical activity-enhanced Parents as Teachers curriculum.

MAIN OUTCOME MEASURES

Multiple-pass 24-hour dietary recalls were collected from participants at the postnatal month 1, 4, 6, 8, and 12 visits. Healthy Eating Index-2010 was used to calculate diet quality.

STATISTICAL ANALYSIS PERFORMED

Linear mixed models were used to test for treatment, time, and treatment by time (interaction) effects on postnatal dietary outcomes.

RESULTS

Control arm mean (95% confidence limits) total Healthy Eating Index-2010 scores were 36.8 (range=32.5 to 41.1), 36.5 (range=31.9 to 41.1), 40.2 (range=35.7 to 44.8), 39.3 (range=34.7 to 43.9), and 36.4 (range=31.8 to 41.0) at postnatal months 1, 4, 6, 8, and 12, respectively. Corresponding experimental arm scores were 42.3 (range=37.5 to 47.0), 41.6 (range=36.3 to 46.9), 40.2 (range=34.8 to 45.7), 45.8 (range=40.5 to 51.1), and 37.6 (range=32.6 to 42.7), respectively. Experimental scores were significantly higher than control scores across time. No other effects were significant.

CONCLUSIONS

Neither the standard Parents as Teachers curriculum nor the enhanced Parents as Teachers curriculum was effective at improving the poor diet quality of this cohort of rural, Southern, African-American women during the 12 months following the birth of their infant.

Interventions for Preventing Unintended, Rapid Repeat Pregnancy Among Adolescents: A Review of the Evidence and Lessons From High-Quality Evaluations

BACKGROUND

In 2017, of the 22.5 million parenting adolescents (ages 15-19) in 60 countries, approximately 4.1 million gave birth to a second or higher-order child. Adolescent pregnancy in general, and rapid repeat pregnancies specifically, expose young mothers and their children to multiple health and socioeconomic risks. The purpose of this article is to review the impact of interventions designed to prevent unintended, rapid repeat pregnancies among adolescents, including those aimed at changing norms to postpone "intended" closely spaced pregnancies to promote healthy spacing.

METHODS

We searched PubMed and other databases for evaluations of interventions published in English from 1990 through 2016. We included evaluations that assessed a programmatic intervention specifically designed to prevent rapid repeat pregnancy (occurring less than 24 months after the index birth) or birth (occurring less than 33 months after the index birth), or that reported on contraceptive continuation for at least 2 years. We first assessed the quality of the evaluations, then ranked the interventions based on the quality of the evaluation and the level of impact on repeat pregnancy or birth (statistically significant impact, positive trends but not statistically significant, or no impact) to identify the most effective interventions. Finally, we extracted program design and implementation lessons from the interventions included in the high-quality evaluations.

RESULTS

Our search identified 2,187 articles, of which 40 evaluations met the inclusion criteria (24=high quality, 14=moderate quality, 2=less rigorous). We found 14 high-quality evaluations in which the intervention achieved a statistically significant impact on repeat pregnancy or birth. These interventions fell into 5 broad categories: (1) contraceptive services and information, with proactive monitoring of contraceptive use and outreach to families; (2) postpartum contraceptive counseling and services provided soon after delivery; (3) activities that help adolescents improve planning skills, including preparing contraceptive plans; (4) social and behavioral change activities that help adolescents understand the role contraception can play in determining positive life outcomes, and the implications of their reproductive health decisions for their future; and (5) activities that provide mentoring, goal setting, and motivation.

CONCLUSION

Effective interventions that prevent rapid adolescent childbearing link clinical contraceptive services with non-clinical activities that build planning skills, enhance understanding of the role that contraceptives can play in determining positive life outcomes, and provide mentoring and goal setting. Recognizing potentially synergistic effects, we recommend testing various combinations of these interventions, with access to contraception as the foundational activity.

To evaluate if increased supervision and support of South African Government health workers' home visits improves maternal and child outcomes: study protocol for a randomized control trial

Background

Concurrent epidemics of HIV, depression, alcohol abuse, and partner violence threaten maternal and child health (MCH) in South Africa. Although home visiting has been repeatedly demonstrated efficacious in research evaluations, efficacy disappears when programs are scaled broadly. In this cluster randomized controlled trial (RCT), we examine whether the benefits of ongoing accountability and supervision within an existing government funded and implemented community health workers (CHW) home visiting program ensure the effectiveness of home visiting.

Methods/Design

In the deeply rural, Eastern Cape of South Africa, CHW will be hired by the government and will be initially trained by the Philani Programme to conduct home visits with all pregnant mothers and their children until the children are 2 years old. Eight clinics will be randomized to receive either (1) the Accountable Care Condition in which additional monitoring and accountability systems that Philani routinely uses are implemented (4 clinics, 16 CHW, 450 households); or (2) a Standard Care Condition of initial Philani training, but with supervision and monitoring being delivered by local government structures and systems (4 clinics, 21 CHW, 450 households). In the Accountable Care Condition areas, the CHW’s mobile phone reports, which are time-location stamped, will be monitored and data-informed supervision will be provided, as well as monitoring growth, medical adherence, mental health, and alcohol use outcomes. Interviewers will independently assess outcomes at pregnancy at 3, 6, 15, and 24 months post-birth. The primary outcome will be a composite score of documenting maternal HIV/TB testing, linkage to care, treatment adherence and retention, as well as child physical growth, cognitive functioning, and child behavior and developmental milestones.

Discussion

The proposed cluster RCT will evaluate whether routinely implementing supervision and accountability procedures and monitoring CHWs’ over time will improve MCH outcomes over the first 2 years of life.

Adapting Current Strategies to Implement Evidence-Based Prevention Programs for Paraprofessional Home Visiting

This paper describes a strategy for using evidence-based interventions (EBI) that does not require replication and fidelity. Eight parents, identified as positive role models, conducted home visits for 101 low-income Latina and Korean pregnant women. The home visitors, called mentor mothers (MM), were trained in 10 of the practice elements common to 80% of child-focused EBI and how to apply these skills to support mothers in obesity prevention, to increase the duration of breastfeeding, and to reduce depression. MM reported the content and skills utilized on each home visit on mobile phones. Each MM made an average of 153 home visits (SD = 173.3), with 28 of these visits being phone contacts. Body mass index (BMI) at 6 months was significantly associated with the frequency of MM focused on coping with depression (r = .24), but was not related to practice elements used by MM. The duration of breastfeeding was significantly related to the frequency with which MM focused on the topic of breastfeeding (r = .28) and parenting (r = .3), and MM use of attending (r = .24) and relaxation (r = .27). Depression was significantly correlated with the frequency of addressing depression (r = .27), but not to practice elements. MM did use different strategies in the first 150 visits compared to their last 150 visits, reflecting data-informed supervision. Evidence synthesized from EBI was used as a novel training method, with real-time monitoring and data-informed supervision providing evidence of iterative quality improvements in MM behaviors over time, as well as a way for linking implementation processes to outcomes.

The Prevention of Child Maltreatment Through the Nurse Family Partnership Program: Mediating Effects in a Long-Term Follow-Up Study

We examine maternal life-course mediators of the impact of a nurse home visitation program on reducing child maltreatment among participants in the Elmira trial of the Nurse Family Partnership program from the first child's birth through age 15. For women having experienced low to moderate levels of domestic violence, program effects on the number of confirmed maltreatment reports were mediated by reductions in numbers of subsequent children born to mothers and their reported use of public assistance. Together, the two mediators explained nearly one half of the total effect of nurse home visiting on child maltreatment. The long-term success of this program on reducing child maltreatment can be explained, at least in part, by its positive effect on pregnancy planning and economic self-sufficiency.

Do children born to teenage parents have lower adult intelligence? A prospective birth cohort study

Teenage motherhood has been associated with a wide variety of negative offspring outcomes including poorer cognitive development. In the context of limitations of previous research, this paper assesses the contemporary relevance of this finding. In this study we investigate the long-term cognitive status (IQ) among 21 year adult offspring born to teenage parents using the Mater University Study of Pregnancy- a prospective birth cohort study, which recruited all pregnant mothers attending a large obstetrical hospital in Brisbane, Australia, from 1981 to 1983. The analyses were restricted to a sub-sample of 2643 mother-offspring pair. Offspring IQ was measured using the Peabody Picture Vocabulary Test at 21 year. Parental age was reported at first clinic visit. Offspring born to teenage mothers (<20 years) have -3.0 (95% Confidence Interval (CI): -4.3, -1.8) points lower IQ compared to children born to mothers ≥20 years and were more likely to have a low IQ (Odds Ratio (OR) 1.7; 95% CI: 1.3, 2.3). Adjustment for a range of confounding and mediating factors including parental socioeconomic status, maternal IQ, maternal smoking and binge drinking in pregnancy, birthweight, breastfeeding and parenting style attenuates the association, though the effect remains statistically significant (-1.4 IQ points; 95% CI: -2.8,-0.1). Similarly the risk of offspring having low IQ remained marginally significantly higher in those born to teenage mothers (OR 1.3; 95% CI: 1.0, 1.9). In contrast, teenage fatherhood is not associated with adult offspring IQ, when adjusted for maternal age. Although the reduction in IQ is quantitatively small, it is indicative of neurodevelopmental disadvantage experienced by the young adult offspring of teenage mothers. Our results suggest that public policy initiatives should be targeted not only at delaying childbearing in the population but also at supporting early life condition of children born to teenage mothers to minimize the risk for disadvantageous outcomes of the next generation.

The Role of Community Health Workers in Preventing Adolescent Repeat Pregnancies and Births

Intervention by community health workers (CHWs) is believed to prevent repeated childbearing among teenagers. This review investigated the effectiveness of CHWs in reducing repeated pregnancies and births among adolescents aged <20 years, 2 years after the delivery of their first child. Through electronic database and hand searching, experimental and/or observational studies were screened with their results undergoing systematic review and meta-analyses. Subgroup analyses were performed to further assess how study characteristics affected the pooled estimates and heterogeneity. A total of 11 eligible articles, from January 1980 to May 2015, were included. Seven studies evaluated repeated births and eight measured repeated pregnancies. Studies showed relevant disparities in terms of selected methodological aspects and program characteristics. Although most studies (n = 9) were either of "strong" or of "moderate" quality, only two of five finding a significant reduction exhibited a high level of quality as the other three failed to adjust results for confounders. Random effects modeling revealed an overall 30% decrease in repeated adolescent births (odds ratio = .70, confidence interval = .49-.99) among CHW-visited areas relative to nonvisited sites. On the other hand, no significant association was detected in terms of repeated pregnancies (odds ratio = .96, confidence interval = .70-1.28).

Using pay-for-success to increase investment in the nonmedical determinants of health

The combination of fee-for-service payments and the US health care system's standing commitment to treating existing illness discourages spending on the behavioral, social, and environmental (that is, the nonmedical) conditions that contribute most to long-term health. Pay-for-success, alternatively known as social impact bonds, or SIBs, offers a possible solution. The pay-for-success model relies on an investor that is willing to fund a nonmedical intervention up front while bearing the risk that the intervention may fail to prevent disease in the future. Should the intervention succeed, however, the investor is repaid in full by a predetermined payer (such as a public health agency) and receives an additional return on its investment as a reward for taking on the risk. Pay-for-success pilots are being developed to reduce asthma-related emergencies among children, poor birth outcomes, and the progression of prediabetes to diabetes, among other applications. These efforts, supported by key policy reforms such as public agency data sharing and coordinated care, promise to increase the number of evidence-based nonmedical service providers and seed a new market that values health, not just health care.

Efficacy of CVD Risk Factor Modification in a Lower-Middle Class Community in Pakistan: The Metroville Health Study

The Metroville Health Study aimed to reduce consumption of total cooking fats by 33%, salt by 25% and replace ghee with vegetable oil in a lower middle class urban community in Pakistan. Households (n=403) were randomly assigned to Intervention and Control groups. A baseline screening collected data on CVD risk factors, knowledge and attitudes and household consumption of cooking fats and salt. Intervention households received information about CVD and regular visits by social workers who measured cooking fats and salt and counselled cooks on the goals of intervention. Two years later, 291 households were re-screened. Intervention households reduced consumption of fats and salt compared to differences were total fat, 48% ( p<0.0001); ghee, 37% ( p=0.005); vegetable oil, 33% ( p=0.0001); and salt, 41% ( p=0.011). Household visits by trained social workers were effective in achieving reductions in consumption of cooking fat and salt in a lower class urban community.

Contextual analysis and the success of translational research

The success of translational research can ultimately be judged by the degree to which it reduces the incidence and prevalence of psychological, behavioral, and physical disorders and the major factors influencing them. In our view, we currently place insufficient emphasis on assessing our impact on the social determinants of disorders. As a result, we are failing to affect the incidence and prevalence of critical disorders. Moreover, translational research fails to take into account the full range of interventions that could significantly reduce the incidence and prevalence of our most pressing disorders. These include policy changes, media, and broad cultural change movements. In this paper, we discuss the momentous achievements the tobacco prevention movement made over the last half-century, describe how the lessons gleaned from this success can apply to other prevention efforts, and contrast this success with progress made in battling other major public health concerns. We call for an expansion of the translational research agenda to develop and evaluate broader and more comprehensive strategies to affect well-being in entire populations.

Implementation of evidence-based home visiting programs aimed at reducing child maltreatment: A meta-analytic review

In recent years there has been an increase in the popularity of home visitation programs as a means of addressing risk factors for child maltreatment. The evidence supporting the effectiveness of these programs from several meta-analyses, however, is mixed. One potential explanation for this inconsistency explored in the current study involves the manner in which these programs were implemented. In the current study we reviewed 156 studies associated with 9 different home visitation program models targeted to caregivers of children between the ages of 0 and 5. Meta-analytic techniques were used to determine the impact of 18 implementation factors (e.g., staff selection, training, supervision, fidelity monitoring, etc.) and four study characteristics (publication type, target population, study design, comparison group) in predicting program outcomes. Results from analyses revealed that several implementation factors, including training, supervision, and fidelity monitoring, had a significant effect on program outcomes, particularly child maltreatment outcomes. Study characteristics, including the program's target population and the comparison group employed, also had a significant effect on program outcomes. Implications of the study's results for those interested in implementing home visitation programs are discussed. A careful consideration and monitoring of program implementation is advised as a means of achieving optimal study results.

Health system and community level interventions for improving antenatal care coverage and health outcomes

BACKGROUND

The World Health Organization (WHO) recommends at least four antenatal care (ANC) visits for all pregnant women. Almost half of pregnant women worldwide, and especially in developing countries do not receive this amount of care. Poor attendance of ANC is associated with delivery of low birthweight babies and more neonatal deaths. ANC may include education on nutrition, potential problems with pregnancy or childbirth, child care and prevention or detection of disease during pregnancy.This review focused on community-based interventions and health systems-related interventions.

OBJECTIVES

To assess the effects of health system and community interventions for improving coverage of antenatal care and other perinatal health outcomes.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (7 June 2015) and reference lists of retrieved studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs), quasi-randomised trials and cluster-randomised trials. Trials of any interventions to improve ANC coverage were eligible for inclusion. Trials were also eligible if they targeted specific and related outcomes, such as maternal or perinatal death, but also reported ANC coverage.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy.

MAIN RESULTS

We included 34 trials involving approximately 400,000 women. Some trials tested community-based interventions to improve uptake of antenatal care (media campaigns, education or financial incentives for pregnant women), while other trials looked at health systems interventions (home visits for pregnant women or equipment for clinics). Most trials took place in low- and middle-income countries, and 29 of the 34 trials used a cluster-randomised design. We assessed 30 of the 34 trials as of low or unclear overall risk of bias. Comparison 1: One intervention versus no interventionWe found marginal improvements in ANC coverage of at least four visits (average odds ratio (OR) 1.11, 95% confidence interval (CI) 1.01 to 1.22; participants = 45,022; studies = 10; Heterogeneity: Tau² = 0.01; I² = 52%; high quality evidence). Sensitivity analysis with a more conservative intra-cluster correlation co-efficient (ICC) gave similar marginal results. Excluding one study at high risk of bias shifted the marginal pooled estimate towards no effect. There was no effect on pregnancy-related deaths (average OR 0.69, 95% CI 0.45 to 1.08; participants = 114,930; studies = 10; Heterogeneity: Tau² = 0.00; I² = 0%; low quality evidence), perinatal mortality (average OR 0.98, 95% CI 0.90 to 1.07; studies = 15; Heterogeneity: Tau² = 0.01; I² = 58%; moderate quality evidence) or low birthweight (average OR 0.94, 95% CI 0.82 to 1.06; studies = five; Heterogeneity: Tau² = 0.00; I² = 5%; high quality evidence). Single interventions led to marginal improvements in the number of women who delivered in health facilities (average OR 1.08, 95% CI 1.02 to 1.15; studies = 10; Heterogeneity: Tau² = 0.00; I² = 0%; high quality evidence), and in the proportion of women who had at least one ANC visit (average OR 1.68, 95% CI 1.02 to 2.79; studies = six; Heterogeneity: Tau² = 0.24; I² = 76%; moderate quality evidence). Results for ANC coverage (at least four and at least one visit) and for perinatal mortality had substantial statistical heterogeneity. Single interventions did not improve the proportion of women receiving tetanus protection (average OR 1.03, 95% CI 0.92 to 1.15; studies = 8; Heterogeneity: Tau² = 0.01; I² = 57%). No study reported onintermittent prophylactic treatment for malaria. Comparison 2: Two or more interventions versus no interventionWe found no improvements in ANC coverage of four or more visits (average OR 1.48, 95% CI 0.99 to 2.21; participants = 7840; studies = six; Heterogeneity: Tau² = 0.10; I² = 48%; low quality evidence) or pregnancy-related deaths (average OR 0.70, 95% CI 0.39 to 1.26; participants = 13,756; studies = three; Heterogeneity: Tau² = 0.00; I² = 0%; moderate quality evidence). However, combined interventions led to improvements in ANC coverage of at least one visit (average OR 1.79, 95% CI 1.47 to 2.17; studies = five; Heterogeneity: Tau² = 0.00; I² = 0%; moderate quality evidence), perinatal mortality (average OR 0.74, 95% CI 0.57 to 0.95; studies = five; Heterogeneity: Tau² = 0.06; I² = 83%; moderate quality evidence) and low birthweight (average OR 0.61, 95% CI 0.46 to 0.80; studies = two; Heterogeneity: Tau² = 0.00; I² = 0%; moderate quality evidence). Meta-analyses for both ANC coverage four or more visits and perinatal mortality had substantial statistical heterogeneity. Combined interventions improved the proportion of women who had tetanus protection (average OR 1.48, 95% CI 1.18 to 1.87; studies = 3; Heterogeneity: Tau² = 0.01; I² = 33%). No trial in this comparison reported on intermittent prophylactic treatment for malaria. Comparison 3: Two interventions compared head to head. No trials found. Comparison 4: One intervention versus a combination of interventionsThere was no difference in ANC coverage (four or more visits and at least one visit), pregnancy-related deaths, deliveries in a health facility or perinatal mortality. No trials in this comparison reported on low birthweight orintermittent prophylactic treatment of malaria.

AUTHORS' CONCLUSIONS

Implications for practice - Single interventions may improve ANC coverage (at least one visit and four or more visits) and deliveries in health facilities. Combined interventions may improve ANC coverage (at least one visit), reduce perinatal mortality and reduce the occurrence of low birthweight. The effects of the interventions are unrelated to whether they are community or health system interventions. Implications for research - More details should be provided in reporting numbers of events, group totals and the ICCs used to adjust for cluster effects. Outcomes should be reported uniformly so that they are comparable to commonly-used population indicators. We recommend further cluster-RCTs of pregnant women and women in their reproductive years, using combinations of interventions and looking at outcomes that are important to pregnant women, such as maternal and perinatal morbidity and mortality, alongside the explanatory outcomes along the pathway of care: ANC coverage, the services provided during ANC and deliveries in health facilities.

Adolescent health experience after abortion or delivery (AHEAD) trial: formative protocol for intervention development to prevent rapid, repeat pregnancy

BACKGROUND

There is a high unmet need for modern contraception among adolescents, and adolescent girls who have already been pregnant are especially vulnerable to a rapid, repeat pregnancy (defined as a subsequent pregnancy within two years). The Adolescent Health Experience after Abortion or Delivery (AHEAD) trial will design, pilot, finalize, and ultimately evaluate an intervention targeted at reducing rapid repeat pregnancy. This protocol presents the methods for the first phase--formative research to identify key determinants of contraceptive use and rapid, repeat unintended pregnancy among adolescents.

METHODS/DESIGN

The determinants of adolescent pregnancy are known to vary by context; therefore, a dissimilar set of three countries will be selected to enable evaluation of the intervention in diverse cultural, political and economic environment, and to allow the intervention to be tested with a fuller range of ever-pregnant adolescents, including those who have chosen to terminate their pregnancy as well as those who are mothers. We will also consider marital status in settings where it is common for adolescents to marry. Focus group discussions (FGDs) will be conducted to examine barriers and facilitators to using contraception; preferred methods of overcoming these barriers; and perceptions of the services and information received. Key informant (KI) interviews will take place with various cadres of healthcare providers, health and education officials, and members of key youth and health organizations that work with adolescents. These interviews will focus on perceptions of pregnant adolescents; perceived information, skills, and motivations required for adolescent uptake of contraception; and experiences, challenges, and attitudes encountered during interactions.

DISCUSSION

The findings from this first formative phase will be used to develop an intervention for preventing rapid, repeat unintended pregnancy among adolescents. This intervention will be piloted in a second phase of the AHEAD trial.

Projected Outcomes of Nurse-Family Partnership Home Visitation During 1996-2013, USA

Nurse-Family Partnership (NFP) targets intensive prenatal and postnatal home visitation by registered nurses to low-income first-time mothers. Through 2013, 177,517 pregnant women enrolled in NFP programs. This article projects how NFP will affect their lives and the lives of their babies. NFP has been evaluated in six randomized trials and several more limited analyses of operational programs. We systematically reviewed evaluation findings on 21 outcomes and calculated effects on three more. We added outcome data from the NFP national data system and personal communications that filled outcome data gaps on some trials. We assumed effectiveness in replication declined by 21.8 %, proportionally with the decline in mean visits per family from trials to operational programs. By 2031, NFP program enrollments in 1996-2013 will prevent an estimated 500 infant deaths, 10,000 preterm births, 13,000 dangerous closely spaced second births, 4700 abortions, 42,000 child maltreatment incidents, 36,000 intimate partner violence incidents, 90,000 violent crimes by youth, 594,000 property and public order crimes (e.g., vandalism, loitering) by youth, 36,000 youth arrests, and 41,000 person-years of youth substance abuse. They will reduce smoking during pregnancy, pregnancy complications, childhood injuries, and use of subsidized child care; improve language development; increase breast-feeding; and raise compliance with immunization schedules. They will eliminate the need for 4.8 million person-months of child Medicaid spending and reduce estimated spending on Medicaid, TANF, and food stamps by $3.0 billion (present values in 2010 dollars). By comparison, NFP cost roughly $1.6 billion. Thus, NFP appears to be a sound investment. It saves money while enriching the lives of participating low-income mothers and their offspring and benefiting society more broadly by reducing crime and safety net demand.

Effectiveness of home visiting in reducing partner violence for families experiencing abuse: a systematic review

BACKGROUND

Intimate partner violence (IPV) against women is a major, global societal problem with enormous health consequences both for mother and child. Home visiting interventions in families at risk of abuse seem promising in decreasing IPV. In this systematic review, we aim to assess the effectiveness of home visiting in reducing IPV experienced by mothers.

METHODS

We conducted a systematic review using the Pubmed, PsychINFO and Embase databases from inception until March 2014, with a specific search strategy for each database.

RESULTS

Of the 1258 articles identified, 19 (six different home visiting studies) met our inclusion criteria and were examined in detail. Three different types of studies were identified: the primary focus of one study was on the abused mother and the secondary focus on the children (Australia); two studies (Hawaii, The Netherlands) with a primarily focus on reduction of child abuse and a secondary focus on IPV and finally three studies from the USA, which only aimed at reducing child abuse by providing support to the mother. The Australian study reported a significant lowering of the IPV score at 1-year follow-up (15.9 versus 21.8, adjusted difference -8.67, 95% confidence interval [CI]: -16.2 to -1.15). The Hawaii-study showed significantly lower rates of physical assault after 3 years follow-up (incidence rate ratio [IRR] 0.85; 95% CI: 0.71-1.00) and the Dutch study showed a significant decrease of mothers' physical assaults 2 years after birth (odds ratio 0.46; 95% CI 0.24-0.89). The other three studies showed no significant reduction of IPV.

CONCLUSIONS

Home visiting interventions that support abused women explicit to stop IPV seem to be effective in reducing IPV. However, it is not known whether these results are effective in the long term.

Long-term home visiting with vulnerable young mothers: an interpretive description of the impact on public health nurses

Background

The Nurse-Family Partnership (NFP) is a targeted, nurse home visitation program for young, low-income, first-time mothers. While the effectiveness of the NFP has been established in the United States, and is currently being evaluated in the Canadian public health care system, we have minimal understanding of how work of this nature impacts public health nurses (PHNs), an essential component of this program delivery model, on both professional and personal levels.

Methods

This two-phase study consisted of a qualitative secondary analysis of data from five focus groups conducted with PHNs (N = 6) who delivered the NFP intervention as part of a pilot study assessing feasibility and acceptability conducted in Hamilton, Ontario. The second phase, an interpretive description of individual interviews with the PHNs (N = 10) who have delivered the NFP in this context, further explored themes identified in the first phase. A practice, problem and needs analysis was conducted to describe and understand the phenomenon and promote sustainability of PHNs in this practice environment. Conventional content analysis was used to code and categorize data in the two datasets.

Results

The nurse-client relationship, the core elements and structure of the NFP program and support of NFP colleagues were described as rewarding factors, while workload and workplace factors were identified as significant contributors to stress. PHNs described transforming their nursing practice through redefining success and shifting to a philosophy where the client is the expert of her own life. PHNs described the personal impact of worry about clients and doubt about their effectiveness in addressing client concerns. High levels of satisfaction were described in relation to the depth and intensity of relationships with clients and seeing them succeed over time.

Conclusions

PHNs are impacted in multiple ways by their work with vulnerable, young mothers. The study findings have implications for identification of strategies to support PHNs in reducing staff turnover, PHN burnout, secondary traumatic stress and compassion fatigue, and improving program delivery.

Maternal health literacy progression among rural perinatal women

This research examined changes in maternal health literacy progression among 106 low income, high risk, rural perinatal African American and White women who received home visits by Registered Nurse Case Managers through the Enterprise Community Healthy Start Program. Maternal health literacy progression would enable women to better address intermediate factors in their lives that impacted birth outcomes, and ultimately infant mortality (Lu and Halfon in Mater Child Health J 7(1):13-30, 2003; Sharma et al. in J Natl Med Assoc 86(11):857-860, 1994). The Life Skills Progression Instrument (LSP) (Wollesen and Peifer, in Life skills progression. An outcome and intervention planning instrument for use with families at risk. Paul H. Brookes Publishing Co., Baltimore, 2006) measured changes in behaviors that represented intermediate factors in birth outcomes. Maternal Health Care Literacy (LSP/M-HCL) was a woman's use of information, critical thinking and health care services; Maternal Self Care Literacy (LSP/M-SCL) was a woman's management of personal and child health at home (Smith and Moore in Health literacy and depression in the context of home visitation. Mater Child Health J, 2011). Adequacy was set at a score of (≥4). Among 106 women in the study initial scores were inadequate (<4) on LSP/M-HCL (83 %), and on LSP/M-SCL (30 %). Significant positive changes were noted in maternal health literacy progression from the initial prenatal assessment to the first (p < .01) postpartum assessment and to the final (p < .01) postpartum assessment using McNemar's test of gain scores. Numeric comparison of first and last gain scores indicated women's scores progressed (LSP/M-HCL; p < .0001) and (LSP/M-SCL; p < .0001). Elevated depression scores were most frequent among women with <4 LSP/M-HCL and/or <4 LSP/M-SCL. Visit notes indicated lack or loss of relationship with the father of the baby and intimate partner discord contributed to higher depression scores.

Effect of home visiting by nurses on maternal and child mortality: results of a 2-decade follow-up of a randomized clinical trial

IMPORTANCE

Mothers and children living in adverse contexts are at risk of premature death.

OBJECTIVE

To determine the effect of prenatal and infant/toddler nurse home visiting on maternal and child mortality during a 2-decade period (1990-2011).

DESIGN, SETTING, AND PARTICIPANTS

A randomized clinical trial was designed originally to assess the home visiting program's effect on pregnancy outcomes and maternal and child health through child age 2 years. The study was conducted in a public system of obstetric and pediatric care in Memphis, Tennessee. Participants included primarily African American women and their first live-born children living in highly disadvantaged urban neighborhoods, who were assigned to 1 of 4 treatment groups: treatment 1 (transportation for prenatal care [n = 166]), treatment 2 (transportation plus developmental screening for infants and toddlers [n = 514]), treatment 3 (transportation plus prenatal/postpartum home visiting [n = 230]), and treatment 4 (transportation, screening, and prenatal, postpartum, and infant/toddler home visiting [n = 228]). Treatments 1 and 3 were included originally to increase statistical power for testing pregnancy outcomes. For determining mortality, background information was available for all 1138 mothers assigned to all 4 treatments and all but 2 live-born children in treatments 2 and 4 (n = 704). Inclusion of children in treatments 1 and 3 was not possible because background information was missing on too many children.

INTERVENTIONS

Nurses sought to improve the outcomes of pregnancy, children's health and development, and mothers' health and life-course with home visits beginning during pregnancy and continuing through child age 2 years.

MAIN OUTCOMES AND MEASURES

All-cause mortality in mothers and preventable-cause mortality in children (sudden infant death syndrome, unintentional injury, and homicide) derived from the National Death Index.

RESULTS

The mean (SE) 21-year maternal all-cause mortality rate was 3.7% (0.74%) in the combined control group (treatments 1 and 2), 0.4% (0.43%) in treatment 3, and 2.2% (0.97%) in treatment 4. The survival contrast of treatments 1 and 2 combined with treatment 3 was significant (P = .007); the contrast of treatments 1 and 2 combined with treatment 4 was not significant (P = .19), and the contrast of treatments 1 and 2 combined with treatments 3 and 4 combined was significant (post hoc P = .008). At child age 20 years, the preventable-cause child mortality rate was 1.6% (0.57%) in treatment 2 and 0.0% (SE not calculable) in treatment 4; the survival contrast was significant (P = .04).

CONCLUSIONS AND RELEVANCE

Prenatal and infant/toddler home visitation by nurses is a promising means of reducing all-cause mortality among mothers and preventable-cause mortality in their first-born children living in highly disadvantaged settings.

The protocol for the Families First Edmonton trial (FFE): a randomized community-based trial to compare four service integration approaches for families with low-income

BACKGROUND

Families with low incomes experience an array of health and social challenges that compromise their resilience and lead to negative family outcomes. Along with financial constraints, there are barriers associated with mental and physical health, poorer education and language. In addition, vulnerable populations experience many services as markedly unhelpful. This combination of family and service barriers results in reduced opportunities for effective, primary-level services and an increased use of more expensive secondary-level services (e.g., emergency room visits, child apprehensions, police involvement). A systematic review of effective interventions demonstrated that promotion of physical and mental health using existing service was critically important.

METHODS/DESIGN

The Families First Edmonton Trial (FFE) tests four service integration approaches to increase use of available health and social services for families with low-income. It is a randomized, two-factor, single-blind, longitudinal effectiveness trial where low-income families (1168) were randomly assigned to receive either (1) Family Healthy Lifestyle plus Family Recreation service integration (Comprehensive), (2) Family Healthy Lifestyle service integration, (3) Family Recreation service integration, or (4) existing services. To be eligible families needed to be receiving one of five government income assistance programs. The trial was conducted in the City of Edmonton between January 2006 and August 2011. The families were followed for a total of three years of which interventional services were received for between 18 and 24 months. The primary outcome is the number of family linkages to health and social services as measured by a customized survey tool "Family Services Inventory". Secondary outcomes include type and satisfaction with services, cost of services, family member health, and family functioning. Where possible, the measures for secondary outcomes were selected because of their standardization, the presence of published norming data, and their utility as comparators to other studies of low-income families. As an effectiveness trial, community and government partners participated in all committees through a mutually agreed upon governance model and helped manage and problem solve with researchers.

DISCUSSION

Modifications were made to the FFE trial based on the pragmatics of community-based trials.

Engaging pregnant and parenting teens: early challenges and lessons learned from the Evaluation of Adolescent Pregnancy Prevention Approaches

This article draws on data from the ongoing federal Evaluation of Adolescent Pregnancy Prevention Approaches to discuss the early implementation experiences of two new and innovative programs intended to delay rapid repeat pregnancy among teen mothers: (1) AIM 4 Teen Moms, in Los Angeles County, California; and (2) Teen Options to Prevent Pregnancy (T.O.P.P.), in Columbus, Ohio. Program staff report common challenges in working with teen mothers, particularly concerning recruitment and retention, staff capacity and training, barriers to participation, and participants' overarching service needs. Lessons learned in addressing these challenges provide useful guidance to program developers, providers, policy makers, and stakeholders working with similar populations.

Development and evaluation of the Korean Health Literacy Instrument

The purpose of this study is to develop and validate the Korean Health Literacy Instrument, which measures the capacity to understand and use health-related information and make informed health decisions in Korean adults. In Phase 1, 33 initial items were generated to measure functional, interactive, and critical health literacy with prose, document, and numeracy tasks. These items included content from health promotion, disease management, and health navigation contexts. Content validity assessment was conducted by an expert panel, and 11 items were excluded. In Phase 2, the 22 remaining items were administered to a convenience sample of 292 adults from community and clinical settings. Exploratory factor and item difficulty and discrimination analyses were conducted and four items with low discrimination were deleted. In Phase 3, the remaining 18 items were administered to a convenience sample of 315 adults 40-64 years of age from community and clinical settings. A confirmatory factor analysis was performed to test the construct validity of the instrument. The Korean Health Literacy Instrument has a range of 0 to 18. The mean score in our validation study was 11.98. The instrument exhibited an internal consistency reliability coefficient of 0.82, and a test-retest reliability of 0.89. The instrument is suitable for screening individuals who have limited health literacy skills. Future studies are needed to further define the psychometric properties and predictive validity of the Korean Health Literacy Instrument.

Caregiver behavior change for child survival and development in low- and middle-income countries: an examination of the evidence

In June of 2012, representatives from more than 80 countries promulgated a Child Survival Call to Action, which called for reducing child mortality to 20 or fewer child deaths per 1,000 live births in every country by 2035. To address the problem of ending preventable child deaths, the U.S. Agency for International Development and the United Nations Children's Fund convened, on June 3-4, 2013, an Evidence Summit on Enhancing Child Survival and Development in Lower- and Middle-Income Countries by Achieving Population-Level Behavior Change. Six evidence review teams were established on different topics related to child survival and healthy development to identify the relevant evidence-based interventions and to prepare reports. This article was developed by the evidence review team responsible for identifying the research literature on caregiver change for child survival and development. This article is organized into childhood developmental periods and cross-cutting issues that affect child survival and healthy early development across all these periods. On the basis of this review, the authors present evidence-based recommendations for programs focused on caregivers to increase child survival and promote healthy development. Last, promising directions for future research to change caregivers' behaviors are given.

Outreach and integration programs to promote family planning in the extended postpartum period

BACKGROUND

WHO recommends birth spacing to improve the health of the mother and child. One strategy to facilitate birth spacing is to improve the use of family planning during the first year postpartum.

OBJECTIVES

To determine from the literature the effectiveness of postpartum family-planning programs and to identify research gaps.

SEARCH STRATEGY

PubMed and the Cochrane Central Register of Controlled Trials were systematically searched for articles published between database inception and March 2013. Abstracts of conference presentations, dissertations, and unpublished studies were also considered.

SELECTION CRITERIA

Published studies with birth spacing or contraceptive use outcomes were included.

DATA COLLECTION AND ANALYSIS

Standard abstract forms and the US Preventive Services Task Force grading system were used to summarize and assess the quality of the evidence.

MAIN RESULTS

Thirty-four studies were included. Prenatal care, home visitation programs, and educational interventions were associated with improved family-planning outcomes, but should be further studied in low-resource settings. Mother-infant care integration, multidisciplinary interventions, and cash transfer/microfinance interventions need further investigation.

CONCLUSIONS

Programmatic interventions may improve birth spacing and contraceptive uptake. Larger well-designed studies in international settings are needed to determine the most effective ways to deliver family-planning interventions.

Effect of teenage motherhood on cognitive outcomes in children: a population-based cohort study

OBJECTIVE

To examine the association between teenage motherhood and cognitive development at 5 years.

DESIGN

Data from Millennium Cohort Study, a prospective, nationally representative UK cohort of 18 818 infants born between 2000 and 2001.

PARTICIPANTS

12 021 (64%) mother-child pairs from white, English-speaking, singleton pregnancies were included.

METHODS

Cognitive ability at 5 years was measured by the British Ability Scales II. Difference in mean cognitive scores across maternal age groups was estimated using linear regression, with adjustment for potential confounders and mediators.

RESULTS

617 (5%) children were born to mothers aged ≤18 years. Our analysis revealed that children of teenage mothers had significantly lower cognitive scores compared with children of mothers aged 25-34 years: difference in mean score for verbal ability -8.9 (-10.88 to -6.86, p<0.001); non-verbal ability -7.8 (-10.52 to -5.19, p<0.001); spatial ability -4.7 (-6.39 to -3.07, p<0.001), which is equivalent to an average delay of 11, 7 and 4 months, respectively. After adjustment for perinatal and sociodemographic factors, the effect of young maternal age on non-verbal and spatial ability mean scores was attenuated. A difference persisted in the mean verbal ability scores -3.8 (-6.34 to -1.34, p=0.003), equivalent to an average delay of 5 months.

CONCLUSIONS

Results suggest that the difference observed in the initial analyses for non-verbal and spatial skills are almost entirely explained by marked inequalities in sociodemographic circumstances and perinatal risk. However, there remains a significant adverse effect on verbal abilities in the children born to teenage mothers.

Adapting evidence-based interventions using a common theory, practices, and principles

Hundreds of validated evidence-based intervention programs (EBIP) aim to improve families' well-being; however, most are not broadly adopted. As an alternative diffusion strategy, we created wellness centers to reach families' everyday lives with a prevention framework. At two wellness centers, one in a middle-class neighborhood and one in a low-income neighborhood, popular local activity leaders (instructors of martial arts, yoga, sports, music, dancing, Zumba), and motivated parents were trained to be Family Mentors. Trainings focused on a framework that taught synthesized, foundational prevention science theory, practice elements, and principles, applied to specific content areas (parenting, social skills, and obesity). Family Mentors were then allowed to adapt scripts and activities based on their cultural experiences but were closely monitored and supervised over time. The framework was implemented in a range of activities (summer camps, coaching) aimed at improving social, emotional, and behavioral outcomes. Successes and challenges are discussed for (a) engaging parents and communities; (b) identifying and training Family Mentors to promote children and families' well-being; and (c) gathering data for supervision, outcome evaluation, and continuous quality improvement. To broadly diffuse prevention to families, far more experimentation is needed with alternative and engaging implementation strategies that are enhanced with knowledge harvested from researchers' past 30 years of experience creating EBIP. One strategy is to train local parents and popular activity leaders in applying robust prevention science theory, common practice elements, and principles of EBIP. More systematic evaluation of such innovations is needed.

How do public child healthcare professionals and primary school teachers identify and handle child abuse cases? A qualitative study

Background

Public child healthcare doctors and nurses, and primary school teachers play a pivotal role in the detection and reporting of child abuse, because they encounter almost all children in the population during their daily work. However, they report relatively few cases of suspected child abuse to child protective agencies. The aim of this qualitative study was to investigate Dutch frontline workers’ child abuse detection and reporting behaviors.

Methods

Focus group interviews were held among 16 primary school teachers and 17 public health nurses and physicians. The interviews were audio recorded, transcribed, and thematically analyzed according to factors of the Integrated Change model, such as knowledge, attitude, self-efficacy, skills, social influences and barriers influencing detection and reporting of child abuse.

Results

Findings showed that although both groups of professionals are aware of child abuse signs and risks, they are also lacking specific knowledge. The most salient differences between the two professional groups are related to attitude and (communication) skills.

Conclusion

The results suggest that frontline workers are in need of supportive tools in the child abuse detection and reporting process. On the basis of our findings, directions for improvement of child abuse detection and reporting are discussed.

The effectiveness and cost-effectiveness of the Family Nurse Partnership home visiting programme for first time teenage mothers in England: a protocol for the Building Blocks randomised controlled trial

BACKGROUND

The Nurse Family Partnership programme was developed in the USA where it is made available to pregnant young mothers in some socially deprived geographic areas. The related Family Nurse Partnership programme was introduced in England by the Department of Health in 2006 with the aim of improving outcomes for the health, wellbeing and social circumstances of young first-time mothers and their children.

METHODS / DESIGN

This multi-centre individually randomised controlled trial will recruit 1600 participants from 18 Primary Care Trusts in England, United Kingdom. The trial will evaluate the effectiveness of Family Nurse Partnership programme and usual care versus usual care for nulliparous pregnant women aged 19 or under, recruited by 24 weeks gestation and followed until the child's second birthday. Data will be collected from participants at baseline, 34-36 weeks gestation, 6, 12, 18 and 24 months following birth. Routine clinical data will be collected from maternity, primary care and hospital episodes statistics. Four primary outcomes are to be reported from the trial: birth weight; prenatal tobacco use; child emergency attendances and/or admissions within two years of birth; second pregnancy within two years of first birth.

DISCUSSION

This trial will evaluate the effectiveness and cost effectiveness of the Family Nurse Partnership in England. The findings will provide evidence on pregnancy and early childhood programme outcomes for policy makers, health professionals and potential recipients in three domains (pregnancy and birth, child health and development, and parental life course and self-sufficiency) up to the child's second birthday.

Vital signs: Repeat births among teens - United States, 2007-2010

BACKGROUND

Teen childbearing has potential negative health, economic, and social consequences for mother and child. Repeat teen childbearing further constrains the mother's education and employment possibilities. Rates of preterm and low birth weight are higher in teens with a repeat birth, compared with first births.

METHODS

To assess patterns of repeat childbearing and postpartum contraceptive use among teens, CDC analyzed natality data from the National Vital Statistics System (NVSS) and the Pregnancy Risk Assessment Monitoring System (PRAMS) from 2007-2010.

RESULTS

Based on 2010 NVSS data from all 50 states and the District of Columbia, of more than 367,000 births to teens aged 15-19 years, 18.3% were repeat births. The percentage of teen births that represented repeat births decreased by 6.2% between 2007 and 2010. Disparities in repeat teen births exist by race/ethnicity, with the highest percentages found among American Indian/Alaska Natives (21.6%), Hispanics (20.9%), and non-Hispanic blacks (20.4%) and lowest among non-Hispanic whites (14.8%). Wide geographic disparities in the percentage of teen births that were repeat births also exist, ranging from 22% in Texas to 10% in New Hampshire. PRAMS data from 16 reporting areas (15 states and New York City) indicate that 91.2% of teen mothers used a contraceptive method 2-6 months after giving birth, but only 22.4% of teen mothers used the most effective methods. Teens with a previous live birth were significantly more likely to use the most effective methods postpartum compared with those with no prior live birth (29.6% versus 20.9%, respectively). Non-Hispanic white and Hispanic teens were significantly more likely to use the most effective methods than non-Hispanic black teens (24.6% and 27.9% versus 14.3%, respectively). The percentage of teens reporting postpartum use of the most effective methods varied greatly geographically across the PRAMS reporting areas, ranging from 50.3% in Colorado to 7.2% in New York State.

CONCLUSIONS

Although the prevalence of repeat teen birth has declined in recent years, nearly one in five teen births is a repeat birth. Large disparities exist in repeat teen births and use of the most effective contraceptive methods postpartum, which was reported by fewer than one out of four teen mothers.

IMPLICATIONS FOR PUBLIC HEALTH PRACTICE

Evidence-based approaches are needed to reduce repeat teen childbearing. These include linking pregnant and parenting teens to home visiting and similar programs that address a broad range of needs, and offering postpartum contraception to teens, including long-acting methods of reversible contraception.

Nine-year follow-up of a home-visitation program: a randomized trial

OBJECTIVE

To evaluate the extent to which a home-visitation program (Early Start) had benefits for child abuse, child behavior, and parental- and family-level benefits to the 9-year follow-up.

METHODS

A randomized controlled trial in which 220 families receiving Early Start were contrasted with a control series of 223 families not receiving the program. Families were enrolled in the program for up to 5 years. Outcomes were assessed at 6 months, annually from 1 year to 6 years, and at 9 years after trial entry.

RESULTS

Comparisons between the Early Start and control series showed that families in the Early Start program showed significant (P < .05) benefits in reduced risk of hospital attendance for unintentional injury, lower risk of parent-reported harsh punishment, lower levels of physical punishment, higher parenting competence scores, and more positive child behavioral adjustment scores. Effect sizes (Cohen's "d") ranged from 0.13 to 0.29 (median = 0.25). There were no significant differences (all P values > .05) between the Early Start and control series on a range of measures of parental behavior and family outcomes, including maternal depression, parental substance use, intimate partner violence, adverse economic outcomes, and life stress.

CONCLUSIONS

The Early Start program was associated with small to moderate benefits in a range of areas relating to child abuse, physical punishment, child behavior, and parenting competence. There was little evidence to suggest that the Early Start program had benefits that extended to the level of parents or family overall.

Home visitation program effectiveness and the influence of community behavioral norms: a propensity score matched analysis of prenatal smoking cessation

Background

The influence of community context on the effectiveness of evidence-based maternal and child home visitation programs following implementation is poorly understood. This study compared prenatal smoking cessation between home visitation program recipients and local-area comparison women across 24 implementation sites within one state, while also estimating the independent effect of community smoking norms on smoking cessation behavior.

Methods

Retrospective cohort design using propensity score matching of Nurse-Family Partnership (NFP) clients and local-area matched comparison women who smoked cigarettes in the first trimester of pregnancy. Birth certificate data were used to classify smoking status. The main outcome measure was smoking cessation in the third trimester of pregnancy. Multivariable logistic regression analysis examined, over two time periods, the association of NFP exposure and the association of baseline county prenatal smoking rate on prenatal smoking cessation.

Results

The association of NFP participation and prenatal smoking cessation was stronger in a later implementation period (35.5% for NFP clients vs. 27.5% for comparison women, p < 0.001) than in an earlier implementation period (28.4% vs. 25.8%, p = 0.114). Cessation was also negatively associated with county prenatal smoking rate, controlling for NFP program effect, (OR = 0.84 per 5 percentage point change in county smoking rate, p = 0.002).

Conclusions

Following a statewide implementation, program recipients of NFP demonstrated increased smoking cessation compared to comparison women, with a stronger program effect in later years. The significant association of county smoking rate with cessation suggests that community behavioral norms may present a challenge for evidence-based programs as models are translated into diverse communities.
