Neighbourhood-level policing as a racialised gendered stressor: multilevel analysis of police stops and preterm birth in Seattle, Washington

BACKGROUND

Most studies capturing the health effects of police violence focus on directly impacted individuals, but a burgeoning field of study is capturing the indirect, community-level health effects of policing. Few empirical studies have examined neighbourhood-level policing, a contextual and racialised gendered stressor, in relation to preterm birth risk among Black and other racially minoritised people.

METHODS

We spatially linked individual birth records (2017-2019) in Seattle, Washington (n=25 909) with geocoded data on police stops for three exposure windows: year before pregnancy, first and second trimester. We fit race-stratified multilevel modified Poisson regression models predicting preterm birth (<37 gestational weeks) across tertiles of neighbourhood stop rates controlling for individual and neighbourhood-level covariates. For the second trimester exposure window, birth was operationalised as a time-to-event outcome using multilevel Cox proportional hazard models.

RESULTS

Neighbourhood stop rates of Black residents was higher compared with White residents, and Black and Asian pregnant people were exposed to the highest median neighbourhood-level stop rates. Black birthing people living in neighbourhoods with more frequent police stops had increased risk of preterm birth across all exposure windows including the year before pregnancy (adjusted risk ratio (aRR): 1.38, 95% CI 1.02 to 1.85), first trimester (aRR:1.74, 95% CI 1.17 to 2.57) and second trimester (aHR: 1.66, 95% CI 1.14 to 2.42). We found null or inverse associations among Asian, Hispanic and White people.

CONCLUSION

Our study adds to the growing evidence documenting associations of higher risk of preterm birth with neighbourhood police stops among Black birthing people. These findings suggest that routine police practices are one aspect of structural racism contributing to racialised perinatal health inequities.

Maternal health-related quality of life at 1 year after a preterm birth: role of socioeconomic status at birth

BACKGROUND

Maternal problems in the postpartum period may lead to suboptimal long-term health for women and could affect mother-child attachment. Social disadvantage is a risk factor for preterm birth, which carries its own burden of health issues and stress. The main aim of this study was to investigate the role for social factors in mothers' physical and emotional health-related quality of life (HRQoL) at 1 year after a preterm birth.

METHODS

EPIPAGE-2 is a French nationwide, prospective, population-based cohort of preterm children born before 35 weeks' gestation (N=3614 women). At birth, detailed data on the family's social status were collected. At 1 year after birth, mothers completed a mailed questionnaire to report information on their HRQoL, assessed by the Medical Outcomes Study 12-item Short Form. We used multivariate linear regression models to assess the association between social factors and maternal HRQoL.

RESULTS

At 1 year after childbirth, the emotional HRQoL of mothers of preterm children was worse than their physical HRQoL, even in women without any previous signs of psychological distress at the infant's discharge from hospital. Baseline social characteristics were the most important factors influencing the physical component of HRQoL. None of the studied social factors had any clear association with the mental component of HRQoL.

CONCLUSION

Our study underlines the importance of social disadvantage during pregnancy as risk factors for poor physical HRQoL at 1 year after a preterm birth.

Using administrative data to evaluate national policy impacts on child and maternal health: a research framework from the Maternal and Child Health Network (MatCHNet)

Reducing health inequalities by addressing the social circumstances in which children are conceived and raised is a societal priority. Early interventions are key to improving outcomes in childhood and long-term into adulthood. Across the UK nations, there is strong political commitment to invest in the early years. National policy interventions aim to tackle health inequalities and deliver health equity for all children. Evidence to determine the effectiveness of socio-structural policies on child health outcomes is especially pressing given the current social and economic challenges facing policy-makers and families with children. As an alternative to clinical trials or evaluating local interventions, we propose a research framework that supports evaluating the impact of whole country policies on child health outcomes. Three key research challenges must be addressed to enable such evaluations and improve policy for child health: (1) policy prioritisation, (2) identification of comparable data and (3) application of robust methods.

Municipal social expenditures and maternal health disparities: a study of linked birth and hospitalisation records

BACKGROUND

Local government expenditures provide services and benefits that can affect health but the extent to which they are associated with narrowing or widening of racial/ethnic and socioeconomic disparities in health is unknown. We examined race/ethnicity-stratified and education-stratified associations between municipal social expenditures-those on housing, transportation, education, and other society-wide needs-and serious life-threatening maternal health conditions in a large US state.

METHODS

In this cross-sectional study, we used individual birth records for 1 003 974 births in the state of New Jersey from 1 January 2008 to 31 December 2018 linked to individual maternal hospital discharge records and municipality-level characteristics for 564 municipalities. Severe maternal morbidity (SMM) was identified in the discharge records using a measure developed by the US Centers for Disease Control and Prevention. Associations between municipal-level social expenditures per capita and SMM were estimated using multilevel logistic models.

RESULTS

Residing in a municipality with higher social expenditures was associated with lower odds of SMM across all racial/ethnic groups and education levels. Overall, 1% higher annual social expenditures per capita was associated with 0.21% (95% CI -0.29 to -0.13) lower odds of SMM. The associations were greater for individuals with less than a high school education than for those in the other educational groups in both relative (lnOR -0.53; 95% CI -0.74 to -0.31) and absolute (β -0.013; 95% CI -0.019 to -0.008) terms.

CONCLUSION

Municipal-level spending on social services is associated with narrowing socioeconomic disparities in SMM. Narrowing racial/ethnic disparities in maternal health will likely require intervening beyond the provision of services to addressing historical and ongoing structural factors.

Impact evaluation of the TAMANI project to improve maternal and child health in Tanzania

BACKGROUND

The Tabora Maternal and Newborn Health Initiative project was a multicomponent intervention to improve maternal and newborn health in the Tabora region of Tanzania. Components included training healthcare providers and community health workers, infrastructure upgrades, and improvements to health management. This study aimed to examine the impact of trainings on four key outcomes: skilled birth attendance, antenatal care, respectful maternity care and patient-provider communication.

METHODS

Trainings were delivered sequentially at four time points between 2018 and 2019 in eight districts (two districts at a time). Cross-sectional surveys were administered to a random sample of households in all districts at baseline and after each training wave. Due to practical necessities, the original stepped wedge cluster randomised design of the evaluation was altered mid-programme. Therefore, a difference-in-differences for multiple groups in multiple periods was adopted to compare outcomes in treated districts to not yet treated districts. Risk differences were estimated for the overall average treatment effect on the treated and group/time dynamic effects.

RESULTS

Respondents reported 3895 deliveries over the course of the study. The intervention was associated with a 12.9 percentage point increase in skilled birth attendance (95% CI 0.4 to 25.4), which began to increase 4 months after the end of training in each district. There was little evidence of impact on antenatal care visits, respectful treatment during delivery and patient-provider communication.

CONCLUSION

Interventions to train local healthcare workers in basic and comprehensive emergency obstetric and newborn care increased skilled birth attendance but had limited impact on other pregnancy-related outcomes.

Associations between Indonesia's national health insurance, effective coverage in maternal health and neonatal mortality: a multilevel interrupted time-series analysis 2000-2017

BACKGROUND

We assessed the effect of Indonesia's national health insurance programme (Jaminan Kesehatan Nasional (JKN)) on effective coverage for maternal and child health across geographical regions and population groups.

METHODS

We used four waves of the Indonesia Demographic and Health Survey from 2000 to 2017, which included 38 880 women aged 15-49 years and 144 000 birth records. Key outcomes included antenatal and delivery care, caesarean section and neonatal and infant mortality. We used multilevel interrupted time-series regression to examine changes in outcomes after the introduction of the JKN in January 2014.

FINDINGS

JKN introduction was associated with significant level increases in (1) antenatal care (ANC) crude coverage (adjusted OR (aOR) 1.81, 95% CI 1.44 to 2.27); (2) ANC quality-adjusted coverage (aOR 1.66, 95% CI 1.38 to 1.98); (3) ANC user-adherence-adjusted coverage (aOR 1.80, 95% CI 1.45 to 2.25); (4) safe delivery service contact (aOR 1.83, 95% CI 1.42 to 2.36); and (5) safe delivery crude coverage (aOR 1.45, 95% CI 1.20 to 1.75). We did not find any significant level increase in ANC service contact or caesarean section. Interestingly, increases in ANC service contact and crude coverage, and safe delivery crude coverage were larger among the poorest compared with the most affluent. No statistically significant associations were found between JKN introduction and neonatal and infant mortality (p>0.05) in the first 3 years following implementation.

INTERPRETATION

Expansion of social health insurance led to substantial improvements in quality of care for maternal health services but not in child mortality. Concerted efforts are required to equitably improve service quality and child mortality across the population in Indonesia.

Interpregnancy and interbirth intervals and all-cause, cardiovascular-related and cancer-related maternal mortality: findings from a large population-based cohort study

INTRODUCTION

Scarce research is available regarding the association between interbirth intervals (IBI) and long-term maternal health outcomes, particularly cardiovascular disease (CVD) mortality. We aimed to assess whether IBIs were associated with all-cause, CVD-related and cancer-related mortality.

METHODS

We conducted a cohort study in the setting of the Jerusalem Perinatal Study. Women with at least two consecutive singleton live births in 1964-1976 (N=18 294) were followed through 2016. IBIs were calculated as the interval between women's first and second cohort birth. We estimated associations between IBIs and mortality using Cox's proportional hazards models, adjusting for age, parity, maternal education, maternal origin and paternal socioeconomic status. Date of last menstrual period was available for a subset of women. We assessed the interpregnancy interval (IPI) for these women and compared the models using IPI and IBI.

RESULTS

During 868 079 years of follow up (median follow-up: 49.0 years), 3337 women died. Women with IBIs <15 months had higher all-cause mortality rates (HR 1.18; 95% CI 1.05 to 1.33) compared to women with 33-month to 68-month IBIs (reference category). IBI and CVD mortality appeared to have a J-shaped association; IBIs of <15, 15-20, 21-2626-2632, 33-68 and ≥69 months had HRs of 1.44, 1.40, 1.33, 1.14, 1.00 and 1.30, respectively. No substantial association was found with cancer mortality. Models using IPIs and those using IBI were similar.

CONCLUSION

Our results support the WHO recommendations for IPIs of ≥24 months and add additional evidence regarding long-term CVD mortality.

Age at first birth and cardiovascular risk factors in the 1958 British birth cohort

BACKGROUND

To assess relationships between age at first birth and cardiovascular risk factors in a large longitudinal study of men and women. By assessing associations for both genders, we were able to investigate biological versus social and behavioural explanations from early life through to adulthood.

METHODS

Multiply-imputed data on more than 7600 men and women of a British birth cohort study (National Child Development Study, 1958 British birth cohort) were used. Cardiovascular risk factors at age 44/45 years included body mass index, waist:hip ratio, blood pressure (systolic and diastolic), cholesterol (total, low and high-density lipoprotein), triglycerides, glycated haemoglobin, C reactive protein, von Willebrand factor and fibrinogen. Age at first birth was categorised as <20 years, 20-24 years, 25-29 years, 30-34 years or >34 years.

RESULTS

Being younger than 20 years of age at time of first birth was associated with an adverse cardiovascular profile by mid-life. Conversely, older parents had a lower cardiovascular risk as captured by lower body mass index, waist:hip ratio, blood pressure, high and low-density lipoprotein cholesterol, triglycerides, glycated haemoglobin, C reactive protein and fibrinogen. The relationship between age at first birth and cardiovascular risk factors was graded. Few differences between men and women were observed. Associations were largely unchanged after adjustment for early life factors but were partially mediated through adult social and behavioural factors.

CONCLUSIONS

Age at first birth is inversely associated with differences in cardiovascular risk factors in mid-life in a large prospective birth cohort. Our results potentially suggest a social and behavioural rather than a biological explanation.

Prenatal sex selection and female infant mortality are more common in India after firstborn and second-born daughters

BACKGROUND

The Indian sex ratio has become highly male-biased in recent decades. This may be attributed to prenatal sex selection (PSS) and excess female infant mortality. However, the question of whether these factors are related has not been adequately studied. Here we examine whether increased use of PSS may offset excess female infant mortality, by reducing the number of 'unwanted' daughters being born.

METHODS

We analyse the National Family Health Survey (NHFS) data sets for India, which contain nationally representative samples of birth histories for women aged 15-49, interviewed in 1992-1993, 1998-1999 and 2005-2006. We test for missing female births at the second and third birth order, by analysis of the frequencies of sibling sex combinations, and examine the mortality differential between male and female infants, controlling for household wealth and sex(es) of older siblings.

RESULTS

PSS was used most in wealthier households at the second and third birth order, when the firstborn, or firstborn and second-born, siblings were female. Having preceding female siblings was a significant risk factor for female infant mortality, but was not correlated with household wealth.

CONCLUSIONS

PSS and female infant mortality increase with the presence of older female siblings, yet we find no evidence that increasing use of PSS prevents female infant mortality, because PSS and the proportion of female infant mortality attributable to having older sisters increased over the study period. Increased pressure on higher birth order females caused by the trend towards smaller family sizes may explain this.

Examining the link between women's exposure to stressful life events prior to conception and infant and toddler health: the role of birth weight

BACKGROUND

The life course perspective suggests a pathway may exist among maternal exposure to stressful life events prior to conception (PSLEs), infant birth weight and subsequent offspring health, whereby PSLEs are part of a 'chains-of-risk' that set children on a certain health pathway. No prior study has examined the link between PSLEs and offspring health in a nationally representative sample of US mothers and their children. We used longitudinal, nationally representative data to evaluate the relation between maternal exposure to PSLEs and subsequent measures of infant and toddler health, taking both maternal and obstetric characteristics into account.

METHODS

We examined 6900 mother-child dyads participating in 2 waves of the nationally representative Early Childhood Longitudinal Study-Birth Cohort (n=6900). Infant and toddler health outcomes assessed at 9 and 24 months included overall health status, special healthcare needs and severe health conditions. Adjusted path analyses examined associations between PSLEs, birth weight and child health outcomes.

RESULTS

In adjusted analyses, PSLEs increased the risk for very low birth weight (VLBW, <1500 g), which, in turn, predicted poor health at both 9 and 24 months of age. Path analyses demonstrated that PSLEs had small indirect effects on children's subsequent health that operated through VLBW.

CONCLUSIONS

Our analysis suggests a chains-of-risk model in which women's exposure to PSLEs increases the risk for giving birth to a VLBW infant, which, in turn, adversely affects infant and toddler health. Addressing women's preconception health may have important downstream benefits for their children, although more research is needed to replicate these findings.

Multilevel assessment of prenatal engagement in home visiting

BACKGROUND

Low engagement in prenatal home visiting may limit programme effectiveness to improve birth outcomes. Multiple factors may influence engagement.

METHODS

A retrospective cohort study of first-time mothers enrolled in home visiting prenatally in southwest Ohio from 2007 to 2010. The primary outcome was enrolment by 20weeks' gestation; a secondary outcome included home visit frequency. Two multilevel assessments were conducted using random intercept multilevel modelling; maternal covariates were nested first within the home visiting agency and then within the ZIP code. In the first model, variations attributable to individual agency and agency volume were assessed. In the second model nested within the ZIP code, violence rates by ZIP code and interaction terms between violence rates and maternal factors were evaluated.

RESULTS

Of 837 women, 25.3% enrolled ≤20 weeks and 7.4% enrolled early and received ≥75% of expected visits. The first model demonstrated a significant variation in early enrolment based on clustering by agency (p<0.001), however, agency volume was not a significant predictor. In the second model, violence rate was not associated with early enrolment (AOR 0.92, p=0.08), but an interaction term with maternal race was significant (p=0.02). The effect of increasing community violence disproportionately affected early enrolment among white women (AOR 0.80, p=0.005) compared with black women (AOR 0.95, p=0.30). In both the random intercept multilevel models, teenagers demonstrated a decreased likelihood of enrolling early (AOR 0.58, p=0.046 and AOR 0.49, p=0.004).

CONCLUSIONS

Prenatal home visiting engagement is related to maternal, agency and community factors, presenting multiple opportunities to optimise programme implementation.

Trajectories of maternal gestational weight gain and child cognition assessed at 5 years of age in a prospective cohort study

BACKGROUND

There has been concern that low gestational weight gain may cause poor fetal neurodevelopment.

METHODS

The association between maternal weight gain and child IQ was examined using serial antenatal weight measurements (median 12) from a prospective cohort of non-obese Scandinavian women (1986-1988). Linear mixed models with piecewise regression were used to estimate participants' (n=552) trimester-specific average rate of weight gain. Linear regression was used to assess the association between weight gain and children's (n=344) full-scale, performance and verbal IQ measured at age 5 using the Wechsler Preschool and Primary Scales of Intelligence-Revised.

RESULTS

Children born to mothers who gained below versus within the 2nd trimester 2009 recommendations tended to have lower IQ scores (Full-scale: 106.6 (SD 15.1) vs 110.2 (15.2), p=0.04; verbal: 102.5 (14.3) vs 105.0 (14.9), p=0.10; performance: 109.5 (15.4) vs 113.4 (14.5), p=0.03). After adjustment there were no differences in child IQ by weight gain adequacy (full-scale: βbelow=-1.1 (95% CI -5.1 to 2.9), βabove=1.5 (-3.8 to 6.8); verbal: βbelow=-0.2 (-3.1 to 2.6), βabove=1.8 (-3.6 to 7.3); performance βbelow=-1.2 (-4.6 to 2.2), βabove=1.0 (-4.6 to 6.7)). No differences were observed based on 3rd trimester adequacy. No differences were observed in IQ scores by quintile of weight gain for any trimester, particularly after adjustment for maternal IQ.

CONCLUSIONS

Our findings are reassuring that among normal weight women, pregnancy weight gain is not associated with child cognitive development. Further investigation should be conducted in contemporary cohorts that also include obese mothers, who are at the greatest risk for low weight gain.

Formative evaluation of a participatory women's group intervention to improve reproductive and women's health outcomes in rural Bangladesh: a controlled before and after study

Background

Women's groups using participatory methods reduced newborn mortality in rural areas of low income countries. Our study assessed a participatory women's group intervention that focused on women's health, nutrition and family planning.

Methods

The study was conducted in three districts in Bangladesh between October 2011 and March 2013, covering a population of around 230 000. On the basis of allocation for the preceding cluster randomised trials, three unions per district were randomly allocated to receive a women's group intervention and three per district were control clusters. Outcomes included unmet need for family planning, morbidity, dietary diversity, night blindness, healthcare decision-making and knowledge of sexual and reproductive health, nutrition and anaemia. A difference-in-difference analysis was used to adjust for secular trends and baseline differences between women taking part in the intervention and a random sample from control clusters.

Results

We interviewed 5355 (91% response rate) women before the intervention and 5128 after (96% response rate). There were significant improvements in women's dietary diversity score (increase of 0.2 (95% CI 0.1 to 0.3)) and participation in healthcare decision-making (proportion increase (95% CI) 14.0% (10.6% to 17.4%)). There were also increases in knowledge about: contraception (4.2% (2.0% to 6.3%)), ways to treat (55.4% (52.2% to 58.5%)) and prevent (71.0% (68.0% to 74.1%)) sexually transmitted infections, nutrition (46.6% (43.6% to 49.6%)) and anaemia prevention (62.8% (60.9% to 64.6%)). There were no significant differences in unmet need for family planning, morbidity or night blindness.

Conclusions

Participatory women's groups have considerable potential to improve women's health knowledge, but evidence of impact on certain outcomes is lacking. Further formative work and intervention development is needed to optimise the impact of this approach for women's health.

Maternal mental health, and child growth and development, in four low-income and middle-income countries

OBJECTIVE

Extend analyses of maternal mental health and infant growth in low- and middle-income countries (LMICs) to children through age eight years, and broaden analyses to cognitive and psychosocial outcomes.

DESIGN

Community-based longitudinal cohort study in four LMICs (Ethiopia, India, Peru and Vietnam). Surveys and anthropometric assessments were carried out when the children were approximately ages 1, 5 and 8 years. Risk of maternal common mental disorders (rCMDs) was assessed with the Self-Reporting Questionnaire (SRQ)-20 (score ≥8).

SETTING

Rural and urban as well as low- and middle-income communities.

PARTICIPANTS

7722 mothers and their children.

MAIN OUTCOME MEASURES

Child stunting and underweight (Z score ≤2 of height and weight for age), and <20th centile for: cognitive development (Peabody Picture Vocabulary Test), and the psychosocial outcomes self pride and life satisfaction.

RESULTS

A high rate of rCMD, stunting and underweight was seen in the cohorts. After adjusting for confounders, significant associations were found between maternal rCMDs and growth variables in the first year of life, with persistence to age 8 years in India and Vietnam, but not in the other countries. India and Vietnam also showed significant associations between rCMDs and lower cognitive development. After adjustment, rCMD was associated with low life satisfaction in Ethiopia but not in the other cohorts.

CONCLUSIONS

Associations of maternal rCMD in the first year of life with child outcomes varied across the study cohorts and, in some cases, persisted across the first 8 years of life of the child, and included growth, cognitive development and psychosocial domains.

Male involvement and maternal health outcomes: systematic review and meta-analysis

BACKGROUND

The developing world accounts for 99% of global maternal deaths. Men in developing countries are the chief decision-makers, determining women's access to maternal health services and influencing their health outcomes. At present, it is unclear whether involving men in maternal health can improve maternal outcomes. This systematic review and meta-analysis aimed to investigate the impact of male involvement on maternal health outcomes of women in developing countries.

METHODS

Four electronic databases and grey literature sources were searched (up to May 2013), together with reference lists of included studies. Two reviewers independently screened and assessed the quality of studies based on prespecified criteria. Measures of effects were pooled and random effect meta-analysis was conducted, where possible.

RESULTS

Fourteen studies met the inclusion criteria. Male involvement was significantly associated with reduced odds of postpartum depression (OR=0.36, 95% CI 0.19 to 0.68 for male involvement during pregnancy; OR=0.34, 95% CI 0.19 to 0.62 for male involvement post partum), and also with improved utilisation of maternal health services (skilled birth attendance and postnatal care). Male involvement during pregnancy and at post partum appeared to have greater benefits than male involvement during delivery.

CONCLUSIONS

Male involvement is associated with improved maternal health outcomes in developing countries. Contrary to reports from developed countries, there was little evidence of positive impacts of husbands' presence in delivery rooms. However, more rigorous studies are needed to improve this area's evidence base.

Folic acid in pregnancy and mortality from cancer and cardiovascular disease: further follow-up of the Aberdeen folic acid supplementation trial

Background

Supplemental periconceptional folic acid is recommended to reduce the risk of fetal neural tube defects. A previous report indicated an elevated risk of breast cancer and all cancer deaths in later life among women randomised by alternate allocation to high-dose (5 mg/day) folic acid in pregnancy compared with placebo; however, findings were based on small numbers of cases. Our aim was to extend the previous analysis by including data from an additional 10 years of follow-up.

Methods

Records of participants in a large (n=2928) trial of folate supplementation (5 or 0.2 mg folic acid, or placebo) in pregnancy in the 1960s were linked to central registries in Scotland. Unadjusted and adjusted HRs were calculated for all-cause, cardiovascular, all cancer and breast cancer mortality, and all cancer and breast cancer morbidity. Analyses were done using (1) data from the time of the previous linkage (2002) to March 2013; and (2) data from 1980 to March 2013.

Results

There was no evidence to suggest an excess risk of morbidity or mortality in either supplementation group compared with placebo for 2002–2013 and no associations were seen for the full time period (1980–2013).

Conclusions

Findings from this extended follow-up do not support our previous observation of an elevated risk of mortality from breast cancer or all cancers in later life among women who had taken 5 mg folic acid/day during pregnancy. Furthermore, there were no associations with risk of mortality from all-causes, all cancers or cardiovascular disease.

Maternal exposure to hurricane destruction and fetal mortality

BACKGROUND

The majority of research documenting the public health impacts of natural disasters focuses on the well-being of adults and their living children. Negative effects may also occur in the unborn, exposed to disaster stressors when critical organ systems are developing and when the consequences of exposure are large.

METHODS

We exploit spatial and temporal variation in hurricane behaviour as a quasi-experimental design to assess whether fetal death is dose-responsive in the extent of hurricane damage. Data on births and fetal deaths are merged with Parish-level housing wreckage data. Fetal outcomes are regressed on housing wreckage adjusting for the maternal, fetal, placental and other risk factors. The average causal effect of maternal exposure to hurricane destruction is captured by difference-in-differences analyses.

RESULTS

The adjusted odds of fetal death are 1.40 (1.07-1.83) and 2.37 (1.684-3.327) times higher in parishes suffering 10-50% and >50% wreckage to housing stock, respectively. For every 1% increase in the destruction of housing stock, we observe a 1.7% (1.1-2.4%) increase in fetal death. Of the 410 officially recorded fetal deaths in these parishes, between 117 and 205 may be attributable to hurricane destruction and postdisaster disorder. The estimated fetal death toll is 17.4-30.6% of the human death toll.

CONCLUSIONS

The destruction caused by Hurricanes Katrina and Rita imposed significant measurable losses in terms of fetal death. Postdisaster migratory dynamics suggest that the reported effects of maternal exposure to hurricane destruction on fetal death may be conservative.

Healthcare utilisation and empowerment among women in Liberia

BACKGROUND

Many efforts have been undertaken to improve access to healthcare services in low-income settings; nevertheless, underutilisation persists. Women's lack of empowerment may be a central reason for underutilisation, but empirical literature establishing this relationship is sparse.

METHODS

We conducted a cross-sectional study using data from the 2007 Liberia Demographic and Health Survey. Our sample included all non-pregnant women who were currently married or living with a partner (N=3925 unweighted). We used multivariate logistic regression to assess the associations between constructs derived from the Theory of Gender and Power (TGP) and healthcare utilisation.

RESULTS

Two-thirds of women (65.6%) had been to a healthcare facility for herself or her children in the past 12 months. Constructs from the three major theoretical structures were associated with healthcare utilisation. Women with no education, compared with women with some education, were less likely to have been to a healthcare facility (OR=0.76; 95% CI 0.62 to 0.93) as were women who had experienced sexual abuse (OR=0.65; 95% CI 0.45 to 0.95) and women who were married (OR=0.69, 95% CI 0.54 to 0.88). Women in higher wealth quintiles, compared with women in the next lower wealth quintile, and women with more decision-making power had greater odds of having been to a healthcare facility (OR=1.22; 95% CI 1.10 to 1.36 and OR=1.10; 95% CI 1.01 to 1.20; respectively).

CONCLUSIONS

Strong associations exist between healthcare utilisation and empowerment among women in Liberia, and gender imbalances are prevalent. This fundamental issue likely needs to be addressed before large-scale improvement in health service utilisation can be expected.

Time series analysis of maternal mortality in Africa from 1990 to 2005

OBJECTIVES

Most global maternal deaths occur in Africa and Asia. In response, the Millennium Development Goal (MDG-5) calls for a 75% reduction in maternal mortality from 1990 to 2015. To assess the potential for progress in MDG-5 in Africa, we examined the cross-sectional and longitudinal associations of socioeconomic, demographic and population-health factors with maternal mortality rates in Africa.

METHODS

We used data from global agencies and the published literature to identify socioeconomic, demographic and population-health explanatory factors that could be correlated with maternal mortality in 49 countries of Africa for the years 1990, 1995, 2000 and 2005. We used correlation, negative binomial and mixed Poisson regression models to investigate whether there exist associations between potential explanatory factors and maternal mortality.

RESULTS

Some African countries have made substantial progress towards achieving MDG-5 while others have fallen behind. Lower gross domestic product (GDP) and female enrolment in primary schools, but higher HIV prevalence, neonatal mortality rate and total fertility rate, were associated with higher maternal mortality.

CONCLUSIONS

Maternal mortality rates in African countries appear to be declining. The mean maternal mortality ratios in Africa decreased from 695.82 in 1990 to 562.18 in 2005. Yet some countries are more likely than others to achieve MDG-5. Better socioeconomic, demographic and population health development appear to be conducive to better maternal health in Africa. Sustained efforts on all these fronts will be needed to close the gap in maternal survival and achieve MDG-5 in Africa.

The role of pregnancy intention in HIV prevention in South Africa: a proposed model for policy and practice

Mother-to-child transmission is a continuing source of new HIV infections in South Africa. The paper posits that insight into the socio-cultural, behavioural, environmental and economic factors that sustain the HIV epidemic is as important as understanding the biological causes of the disease when planning and implementing interventions to prevent and reduce perinatal transmission. Furthermore, understanding the pregnancy intentions of individuals in areas of endemic HIV/AIDS is vital for providing the best care for individuals who are HIV-positive. This paper suggests a model for types of support and interventions that are relative to the intention of HIV-positive women or couples to become pregnant. Included among these are interventions for prevention of unwanted pregnancy, prevention of transmission of HIV, protection of the infant, and protection of the mother.
