Impact of paternal presence and parental social-demographic characteristics on birth outcomes

OBJECTIVES

Maternal race, marital status, and social environment impact risk of preterm delivery and size for gestational age. Although some paternal characteristics such as age are associated with pregnancy outcomes, the influence of the paternal presence, race/ethnicity and adverse life events is not well known. The objective of the study was to assess birth outcomes in mothers with a paternal presence compared to those without during the post-partum period. The secondary aim was to determine whether paternal race is associated with birth outcomes.

METHODS

This was a cross-sectional study using parental surveys linked with birth certificate data from 2016 to 2018. Adverse birth composite outcomes (ABCO) including small for gestational age (SGA), prematurity or neonatal intensive care unit admission (NICU) were assessed.

RESULTS

A total of 695 parents were analyzed (239 single mothers and 228 mother-father pairs). Compared to mothers with a father present, mothers without a father present exhibited increased odds of ABCO, prematurity and NICU. Non-Hispanic Black fathers had increased odds of ABCO and NICU compared to Non-Hispanic Whites (NHW). Hispanic fathers had increased odds of NICU compared to NHW.

CONCLUSIONS

Paternal absence in the post-partum period and paternal race were both independently associated with ABCO and NICU. Assessment of paternal presence and paternal race in clinical practice may help identify opportunities for additional support necessary to optimize birth outcomes.

Parental education and inequalities in child mortality: a global systematic review and meta-analysis

BACKGROUND

The educational attainment of parents, particularly mothers, has been associated with lower levels of child mortality, yet there is no consensus on the magnitude of this relationship globally. We aimed to estimate the total reductions in under-5 mortality that are associated with increased maternal and paternal education, during distinct age intervals.

METHODS

This study is a comprehensive global systematic review and meta-analysis of all existing studies of the effects of parental education on neonatal, infant, and under-5 child mortality, combined with primary analyses of Demographic and Health Survey (DHS) data. The literature search of seven databases (CINAHL, Embase, MEDLINE, PsycINFO, PubMed, Scopus, and Web of Science) was done between Jan 23 and Feb 8, 2019, and updated on Jan 7, 2021, with no language or publication date restrictions. Teams of independent reviewers assessed each record for its inclusion of individual-level data on parental education and child mortality and excluded articles on the basis of study design and availability of relevant statistics. Full-text screening was done in 15 languages. Data extracted from these studies were combined with primary microdata from the DHS for meta-analyses relating maternal or paternal education with mortality at six age intervals: 0-27 days, 1-11 months, 1-4 years, 0-4 years, 0-11 months, and 1 month to 4 years. Novel mixed-effects meta-regression models were implemented to address heterogeneity in referent and exposure measures among the studies and to adjust for study-level covariates (wealth or income, partner's years of schooling, and sex of the child). This study was registered with PROSPERO (CRD42020141731).

FINDINGS

The systematic review returned 5339 unique records, yielding 186 included studies after exclusions. DHS data were compiled from 114 unique surveys, capturing 3 112 474 livebirths. Data extracted from the systematic review were synthesized together with primary DHS data, for meta-analysis on a total of 300 studies from 92 countries. Both increased maternal and paternal education showed a dose-response relationship linked to reduced under-5 mortality, with maternal education emerging as a stronger predictor. We observed a reduction in under-5 mortality of 31·0% (95% CI 29·0-32·6) for children born to mothers with 12 years of education (ie, completed secondary education) and 17·3% (15·0-18·8) for children born to fathers with 12 years of education, compared with those born to a parent with no education. We also showed that a single additional year of schooling was, on average, associated with a reduction in under-5 mortality of 3·04% (2·82-3·23) for maternal education and 1·57% (1·35-1·72) for paternal education. The association between higher parental education and lower child mortality was significant for both parents at all ages studied and was largest after the first month of life. The meta-analysis framework incorporated uncertainty associated with each individual effect size into the model fitting process, in an effort to decrease the risk of bias introduced by study design and quality.

INTERPRETATION

To our knowledge, this study is the first effort to systematically quantify the transgenerational importance of education for child survival at the global level. The results showed that lower maternal and paternal education are both risk factors for child mortality, even after controlling for other markers of family socioeconomic status. This study provides robust evidence for universal quality education as a mechanism to achieve the Sustainable Development Goal target 3.2 of reducing neonatal and child mortality.

Beyond childcare: Changes in the amount and types of parent-child time over three decades

Parents' time with children has increased over the past several decades, according to many scholars. Yet, research predominantly focuses on childcare activities, overlooking the majority of time that parents spend with children. Using time diaries from the 1986-2015 Canadian General Social Survey, we examine trends in the quantity and distribution of parents' childcare time and total co-present time in the company of children, as well as the behavioral or compositional drivers of these trends. Co-present time with children increased sharply since the mid-1980s, by 1 hour per day for fathers and 1.5 hours for mothers. This rise was driven not only by childcare activities, but also parents' time in housework and mothers' time in leisure with children present. Decomposition analyses indicate that changes in parenting behavior primarily explain these increases in co-present time. This study expands knowledge on intensive parenting through a more comprehensive understanding of parents' daily lives with children.

The male breadwinner nuclear family is not the 'traditional' human family, and promotion of this myth may have adverse health consequences

The importance of social support for parental and child health and wellbeing is not yet sufficiently widely recognized. The widespread myth in Western contexts that the male breadwinner-female homemaker nuclear family is the 'traditional' family structure leads to a focus on mothers alone as the individuals with responsibility for child wellbeing. Inaccurate perceptions about the family have the potential to distort academic research and public perceptions, and hamper attempts to improve parental and child health. These perceptions may have arisen partly from academic research in disciplines that focus on the Western middle classes, where this particular family form was idealized in the mid-twentieth century, when many of these disciplines were developing their foundational research. By contrast, evidence from disciplines that take a cross-cultural or historical perspective shows that in most human societies, multiple individuals beyond the mother are typically involved in raising children: in evolutionary anthropology, it is now widely accepted that we have evolved a strategy of cooperative reproduction. Expecting mothers to care for children with little support, while expecting fathers to provide for their families with little support, is, therefore, likely to lead to adverse health consequences for mothers, fathers and children. Incorporating evidence-based evolutionary, and anthropological, perspectives into research on health is vital if we are to ensure the wellbeing of individuals across a wide range of contexts. This article is part of the theme issue 'Multidisciplinary perspectives on social support and maternal-child health'.

Male partner participation in maternity care and social support for childbearing women: a discussion paper

Male partners/fathers are key support persons for many childbearing women and their involvement in pregnancy, childbirth and the postpartum/postnatal period has beneficial effects on a wide range of outcomes related to maternal and child health and family wellbeing. Social support is implicated in the relevant causal pathway, but has received largely tangential attention in the public health literature. This discussion paper aims to reframe men's participation in maternity care as an opportunity to enhance their readiness and ability to provide social support to women, contributing to the debate on the definition and rationale for male partner involvement, and paving the way for further empirical work. I begin by presenting a theory of change illustrating the causal pathway leading from male partner participation, through the key intermediate step of social support, to improved health and wellbeing for women and children. I proceed by arguing that many people desire male partner participation in maternity care; however, in practice, this is often limited owing to cultural, social and institutional barriers. I use examples from the intervention literature to demonstrate how participation in care can boost men's motivation to support women and enhance their ability to do so by increasing their knowledge and skills. Finally, I draw up general implications for further male partner involvement programmes, suggesting that in order to achieve meaningful and sustainable gains, attention to design is crucial in order to avoid reinforcing patriarchal gender norms. Programmes should be implemented alongside other efforts to improve quality and promote woman-centred care.

Was Cinderella just a fairy tale? Survival differences between stepchildren and their half-siblings

The death of a parent, particularly the mother, is linked to a suite of negative outcomes across the life-course. Compounding concerns for child outcomes are expectations of poor treatment by step-parents after parental remarriage. Indeed, folk tales of step-parental abuse abound cross-culturally and are embedded into stories taught to children. To understand why child outcomes might be sensitive to levels of relatedness within the household, evolutionary-oriented research targets patterning in parental expenditure in ways predicted to maximize inclusive fitness. In particular, parents are expected to prioritize investments in their biological children. However, stepfamilies are only formed after children experience multiple unfortunate events (e.g. parental loss, poverty), blurring causal interpretations between step-parental presence and stepchild outcomes. Moreover, stepchildren have been shown to be integral to household functioning, caring for their half-siblings and stabilizing relationships. These results challenge narrow views of adaptive behaviour; specifically, that step-parents, unlike biological parents, do no stand to reap fitness benefits from the care that they provide to their stepchildren. To evaluate these critiques, we analyse the survival outcomes of stepchildren. We include over 400 000 individuals from across a natural fertility period (1847-1940) in the United States state of Utah and examine the consequences of parental loss and step-parental introduction. Our analyses yield three key results: (i) exposure to maternal loss in childhood is associated with elevated mortality risk, (ii) parental remarriage does not increase the risk of mortality among stepchildren compared to non-stepchildren who too had lost a parent, and (iii) stepchildren enjoy higher survival than their half-siblings within the same family. Ultimately, this work contributes to the increasingly recognized importance of cooperative relationships among non-kin for childcare and household functioning. This article is part of the theme issue 'Multidisciplinary perspectives on social support and maternal-child health'.

Effect of Maternal Prepregnancy/Early-Pregnancy Body Mass Index and Pregnancy Smoking and Alcohol on Congenital Heart Diseases: A Parental Negative Control Study

Background Congenital heart diseases (CHDs) are the most common congenital anomaly. The causes of CHDs are largely unknown. Higher prenatal body mass index (BMI), smoking, and alcohol consumption are associated with increased risk of CHDs. Whether these are causal is unclear. Methods and Results Seven European birth cohorts, including 232 390 offspring (2469 CHD cases [1.1%]), were included. We applied negative exposure paternal control analyses to explore the intrauterine effects of maternal BMI, smoking, and alcohol consumption during pregnancy, on offspring CHDs and CHD severity. We used logistic regression, adjusting for confounders and the other parent's exposure and combined estimates using a fixed-effects meta-analysis. In adjusted analyses, maternal overweight (odds ratio [OR], 1.15 [95% CI, 1.01-1.31]) and obesity (OR, 1.12 [95% CI, 0.93-1.36]), compared with normal weight, were associated with higher odds of CHD, but there was no clear evidence of a linear increase in odds across the whole BMI distribution. Associations of paternal overweight, obesity, and mean BMI were similar to the maternal associations. Maternal pregnancy smoking was associated with higher odds of CHD (OR, 1.11 [95% CI, 0.97-1.25]) but paternal smoking was not (OR, 0.96 [95% CI, 0.85-1.07]). The positive association with maternal smoking appeared to be driven by nonsevere CHD cases (OR, 1.22 [95% CI, 1.04-1.44]). Associations with maternal moderate/heavy pregnancy alcohol consumption were imprecisely estimated (OR, 1.16 [95% CI, 0.52-2.58]) and similar to those for paternal consumption. Conclusions We found evidence of an intrauterine effect for maternal smoking on offspring CHDs, but no evidence for higher maternal BMI or alcohol consumption. Our findings provide further support for the importance of smoking cessation during pregnancy.

The relationship between socioeconomic status and childhood overweight/obesity is linked through paternal obesity and dietary intake: a cross-sectional study in Chongqing, China

BACKGROUND

The prevalence of obesity and overweight in childhood has increased dramatically over the past decades globally. Thus, the risk factors of overweight and obesity in children and adolescents must be studied.

OBJECTIVES

This study aimed to reveal the prevalence of childhood obesity and examine the relationship between socioeconomic status (SES) and z-body mass index (z-BMI) via parental obesity and dietary intake using path analysis.

METHODS

Stratified cluster sampling was used to select 17,007 participants aged 6-12 years on two avenues per region in urban, suburban, and rural areas. Path analysis was conducted to examine the mediators between SES and z-BMI.

RESULTS

The prevalence rates of overweight and obesity were 13.36% and 8.60%, respectively, and were positively correlated with the father's education level, family income, a birth weight > 3000g, a parental obesity history, vegetable intake and red meat intake (all P < 0.05). Four mediators (paternal obesity history, red meat intake, vegetable intake, and nutritional supplements) were observed, and the four path analyses were significant (all P < 0.05). The adjusted total effects on z-BMI were significant for income (β_Tot = 0.03; P < 0.01), father's education (β_Tot = 0.05; P < 0.001), and region (β_Tot = 0.11; P<0.001), and the total mediation effects were 20.69%, 16.67%, and 5.36%, respectively. All the variables accounted for 12.60% of the z-BMI variance.

CONCLUSIONS

The prevalence of overweight/obesity in children was notable, and the relationship between SES and z-BMI was mediated by paternal obesity history and dietary intake.

Postnatal care coverage and its determinants in Sri Lanka: analysis of the 2016 demographic and health survey

BACKGROUND

Postnatal care (PNC) is important for preventing morbidity and mortality in mothers and newborns. Even though its importance is highlighted, PNC received less attention than antenatal care. This study determines the level of PNC coverage and its determinants in Srilanka.

METHODS

This is a secondary analysis of the 2016 Demographic and Health Survey. Receiving full postnatal care (FPNC) was defined with a set of indicators to detect adequate care for mother and newborn. Demographic and socio-economic associated factors for receiving FPNC were identified using binary and multiple logistic regression. Variables that had marginal relationship with receiving FPNC which p-value less than or equal to 0.2 at binary analysis were selected and included in the multiple logistic regression models. We used manual backward stepwise regression to identify variables which had independent association with receiving FPNC on the basis of adjusted odds ratios (AOR), with 95% confidence interval (CI) and p-value less than 0.05. All analyses were performed in SPSS 25.

RESULTS

Of the 8313 women with a live birth in the last 5 years, more than 98% had received postnatal care at facility at least 24 h. More than three-fourth of mothers (n = 5104) received the FPNC according to WHO guideline. Four factors were positively associated with receiving FPNC: mothers received antenatal home visits by Public health midwife (AOR = 1.98, 95% CI 1.65-2.39), mothers who got information about antenatal complications and places to go at antenatal clinics (AOR = 1.56, 95% CI 1.27-1.92), been Sinhala (AOR = 1.89, 95% CI 1.35-2.66) and having own mobile phone (AOR = 1.19, 95% CI 1.02-1.38). Mothers who are residing in rural area (AOR = 0.697 95% CI = 0.52-0.93] compared to those who reside in urban areas and maternal age between 20 and 34 years [AOR = 0.72, 95% CI 0.54-0.97] compared to maternal age less than 20 years were detected as negatively associated.

CONCLUSION

Receiving FPNC in Srilanka is high. However, inequity remains to be a challenge. Socio-demographic factors are associated with FPNC coverage. Strategies that aim to improve postnatal care should target improvement of non-health factors as well.

Association Between Paternal Separation During Early Childhood and Pubertal Timing Among Girls Using Longitudinal Birth Cohort in Japan

INTRODUCTION

Previous studies have shown that paternal absence leads to earlier pubertal timing among girls in high-income countries. Despite the low divorce rate in Japan, paternal separation is commonly seen due to a unique corporation system, tanshin funin, where employees relocate with their spouses and children. We examined paternal separation, including paternal absence (due to divorce or paternal death) and paternal tanshin funin, during early childhood as a predictor of earlier girl's pubertal development, assessed as age at peak height velocity (PHV).

METHODS

This study examined 15 214 girls from a longitudinal survey conducted in Japan from 2001 to 2016 by the Ministry of Health, Labor and Welfare. Paternal separation was determined by the occurrence through annual surveys conducted at ages 0.5 to 4.5 years. Outcome was defined as age at PHV between ages 6 to 15 years. We conducted linear regression, adjusted for potential confounders and other covariates.

RESULTS

Continuous father cohabitation was seen in 88.7% of households, while paternal separation was experienced 1-2, 3-4 and 5 times (always) among 7.4%, 2.8% and 1.1% of households, respectively. Girls who confronted continuous paternal separation (5 times) experienced 0.42 years earlier [95% confidence interval (CI): -0.75, -0.10] age at PHV compared to their peers who always lived with their fathers.

CONCLUSION

Girls who experienced paternal separation throughout ages 0.5 to 4.5 years experienced PHV earlier.

Advanced paternal age and risk of cancer in offspring

Many risk factors of cancer have been established, but the contribution of paternal age in this regard remains largely unexplored. To further understand the etiology of cancer, we investigated the relationship between paternal age and cancer incidence using PLCO cohort. Cox proportional hazards models were performed to assess the association between paternal age and the risk of cancers. During follow-up time (median 11.5 years), 18,753 primary cancers occurred. Paternal age was associated with reduced risk of cancers of the female genitalia (HR, 0.79; 95%CI, 0.66-0.94; P = 0.008) as well as cancers of the respiratory and intrathoracic organs (HR, 0.78; 95%CI, 0.63-0.97; P = 0.026). The association was stronger for lung cancer (HR, 0.67; 95%CI, 0.52-0.86; P = 0.002). The subgroup analysis suggested that age, gender, smoking and BMI were related to the decreased cancer incidence of the respiratory and intrathoracic organs, lung and the female genitalia. Positive linear associations were observed between paternal age and cancer incidence of the female genitalia, respiratory and intrathoracic organs and the lungs. These findings indicate that advanced paternal age is an independent protective factor against various cancers in offspring.

Paternal country of origin and adverse neonatal outcomes in births to foreign-born women in Norway: A population-based cohort study

BACKGROUND

Migration is a risk factor for adverse neonatal outcomes. The various impacts of maternal origin have been reported previously. The aim of this study was to investigate associations between paternal origin and adverse neonatal outcomes in births to migrant and Norwegian-born women in Norway.

METHODS AND FINDINGS

This nationwide population-based study included births to migrant (n = 240,759, mean age 29.6 years [±5.3 SD]) and Norwegian-born women (n = 1,232,327, mean age 29.0 years [±5.1 SD]) giving birth in Norway in 1990-2016. The main exposure was paternal origin (Norwegian-born, foreign-born, or unregistered). Neonatal outcomes were very preterm birth (22+0-31+6 gestational weeks), moderately preterm birth (32+0-36+6 gestational weeks), small for gestational age (SGA), low Apgar score (<7 at 5 minutes), and stillbirth. Associations were investigated in migrant and Norwegian-born women separately using multiple logistic regression and reported as adjusted odds ratios (aORs) with 95% confidence intervals (CIs), adjusted for year of birth, parity, maternal and paternal age, marital status, maternal education, and mother's gross income. In births to migrant women, a foreign-born father was associated with increased odds of very preterm birth (1.1% versus 0.9%, aOR 1.20; CI 1.08-1.33, p = 0.001), SGA (13.4% versus 9.5%, aOR 1.48; CI 1.43-1.53, p < 0.001), low Apgar score (1.7% versus 1.5%, aOR 1.14; CI 1.05-1.23, p = 0.001), and stillbirth (0.5% versus 0.3%, aOR 1.26; CI 1.08-1.48, p = 0.004) compared with a Norwegian-born father. In Norwegian-born women, a foreign-born father was associated with increased odds of SGA (9.3% versus 8.1%, aOR 1.13; CI 1.09-1.16, p < 0.001) and decreased odds of moderately preterm birth (4.3% versus 4.4%, aOR 0.95; CI 0.91-0.99, p = 0.015) when compared with a Norwegian-born father. In migrant women, unregistered paternal origin was associated with increased odds of very preterm birth (2.2% versus 0.9%, aOR 2.29; CI 1.97-2.66, p < 0.001), moderately preterm birth (5.6% versus 4.7%, aOR 1.15; CI 1.06-1.25, p = 0.001), SGA (13.0% versus 9.5%, aOR 1.50; CI 1.42-1.58, p < 0.001), low Apgar score (3.4% versus 1.5%, aOR 2.23; CI 1.99-2.50, p < 0.001), and stillbirth (1.5% versus 0.3%, aOR 4.87; CI 3.98-5.96, p < 0.001) compared with a Norwegian-born father. In Norwegian-born women, unregistered paternal origin was associated with increased odds of very preterm birth (4.6% versus 1.0%, aOR 4.39; CI 4.05-4.76, p < 0.001), moderately preterm birth (7.8% versus 4.4%, aOR 1.62; CI 1.53-1.71, p < 0.001), SGA (11.4% versus 8.1%, aOR 1.30; CI 1.24-1.36, p < 0.001), low Apgar score (4.6% versus 1.3%, aOR 3.51; CI 3.26-3.78, p < 0.001), and stillbirth (3.2% versus 0.4%, aOR 9.00; CI 8.15-9.93, p < 0.001) compared with births with a Norwegian-born father. The main limitations of this study were the restricted access to paternal demographics and inability to account for all lifestyle factors.

CONCLUSION

We found that a foreign-born father was associated with adverse neonatal outcomes among births to migrant women, but to a lesser degree among births to nonmigrant women, when compared with a Norwegian-born father. Unregistered paternal origin was associated with higher odds of adverse neonatal outcomes in births to both migrant and nonmigrant women when compared with Norwegian-born fathers. Increased attention to paternal origin may help identify women in maternity care at risk for adverse neonatal outcomes.

Advanced paternal age is associated with an increased risk of spontaneous miscarriage: a systematic review and meta-analysis

BACKGROUND

Although spontaneous miscarriage is the most common complication of human pregnancy, potential contributing factors are not fully understood. Advanced maternal age has long been recognised as a major risk factor for miscarriage, being strongly related with fetal chromosomal abnormalities. The relation between paternal age and the risk of miscarriage is less evident, yet it is biologically plausible that an increasing number of genetic and epigenetic sperm abnormalities in older males may contribute to miscarriage. Previous meta-analyses showed associations between advanced paternal age and a broad spectrum of perinatal and paediatric outcomes. This is the first systematic review and meta-analysis on paternal age and spontaneous miscarriage.

OBJECTIVE AND RATIONALE

The aim of this systematic review and meta-analysis is to evaluate the effect of paternal age on the risk of spontaneous miscarriage.

SEARCH METHODS

PubMed, Embase and Cochrane databases were searched to identify relevant studies up to August 2019. The following free text and MeSH terms were used: paternal age, father's age, male age, husband's age, spontaneous abortion, spontaneous miscarriage, abortion, miscarriage, pregnancy loss, fetal loss and fetal death. PRISMA guidelines for systematic reviews and meta-analysis were followed. Original research articles in English language addressing the relation between paternal age and spontaneous miscarriage were included. Exclusion criteria were studies that solely focused on pregnancy outcomes following artificial reproductive technology (ART) and studies that did not adjust their effect estimates for at least maternal age. Risk of bias was qualitatively described for three domains: bias due to confounding, information bias and selection bias.

OUTCOMES

The search resulted in 975 original articles. Ten studies met the inclusion criteria and were included in the qualitative synthesis. Nine of these studies were included in the quantitative synthesis (meta-analysis). Advanced paternal age was found to be associated with an increased risk of miscarriage. Pooled risk estimates for miscarriage for age categories 30-34, 35-39, 40-44 and ≥45 years of age were 1.04 (95% CI 0.90, 1.21), 1.15 (0.92, 1.43), 1.23 (1.06, 1.43) and 1.43 (1.13, 1.81) respectively (reference category 25-29 years). A second meta-analysis was performed for the subgroup of studies investigating first trimester miscarriage. This showed similar pooled risk estimates for the first three age categories and a slightly higher pooled risk estimate for age category ≥45 years (1.74; 95% CI 1.26, 2.41).

WIDER IMPLICATIONS

Over the last decades, childbearing at later ages has become more common. It is known that frequencies of adverse reproductive outcomes, including spontaneous miscarriage, are higher in women with advanced age. We show that advanced paternal age is also associated with an increased risk of spontaneous miscarriage. Although the paternal age effect is less pronounced than that observed with advanced maternal age and residual confounding by maternal age cannot be excluded, it may have implications for preconception counselling of couples comprising an older aged male.

Risk factors of child mortality in Ethiopia: Application of multilevel two-part model

The child mortality rate is an essential measurement of socioeconomic growth and the quality of life in Ethiopia which is one among the six countries that account for half of the global under-five deaths. Therefore, this study aimed to identify the potential risk factors for child mortality in Ethiopia. Data for the study was drawn from the Ethiopian Demographic and Health Survey data conducted in 2016. A two-part random effects regression model was employed to identify the associated predictors of child mortality. The study found that 53.3% of mothers did not face any child death, while 46.7% lost at least one. Vaccinated child (IRR = 0.735, 95%CI: 0.647, 0.834), were currently using contraceptive (IRR = 0.885, 95%CI: 0.814, 0.962), who had antenatal care visit four or more times visit (IRR = 0.841, 95%CI: 0.737,0.960), fathers whose level of education is secondary or above(IRR = 0.695, 95%CI: 0.594, 0.814), mothers who completed their primary school(IRR = 0.785, 95%CI: 0.713, 0.864), mothers who have birth interval greater than 36 months (IRR = 0.728, 95%CI: 0.676, 0.783), where the age of the mother at first birth is greater than 16 years(IRR = 0.711, 95%CI: 0.674, 0.750) associated with the small number of child death. While multiple births (IRR = 1.355, 95%CI: 1.249, 1.471, four and above birth order (IRR = 1.487, 95%CI: 1.373, 1.612) and had working father (IRR = 1.125, 95%CI: 1.049, 1.206) associated with a higher number of child death. The variance components for the random effects showed significant variation of child mortality between enumeration areas. Policies and programs aimed at addressing enumeration area variations in child mortality need to be formulated and their implementation must be strongly pursued. Efforts are also needed to extend educational programmers aimed at educating mothers on the benefits of the antenatal checkup before first birth, spacing their birth interval, having their child vaccinated, and selecting a safe place of delivery to reduce child mortality.

The Role of Paternal Accommodation of Paediatric OCD Symptoms: Patterns and Implications for Treatment Outcomes

Family accommodation (FA) refers to the participation of family members in obsessive-compulsive disorder (OCD) rituals. Most studies have focused on maternal accommodation; consequently, little is known about fathers’ accommodation of OCD. The current study aims to extend the existing literature by examining maternal versus paternal accommodation of OCD symptoms.

The sample consisted of 209 children with OCD (Mean [M] age = 14.1 years) and their parents (N_Mothers = 209, N_Fathers = 209) who had completed the Family Accommodation Scale- Parent Report (FAS-PR). Paired t-test and chi-square analyses were used to compare FA of OCD symptoms between mothers and fathers. Linear regression was used to examine correlates of maternal and paternal FA and its impact on treatment outcomes.

Mothers reported significantly higher levels of daily FA than fathers. Correlates of maternal and paternal accommodation included OCD symptom severity, emotional and behavioral difficulties, and parent psychopathology. Both maternal and paternal FA significantly predicted worse treatment outcomes.

Both mothers and fathers accommodate child OCD symptoms with high frequency, and in similar ways. Although mothers accommodate to a greater extent than fathers, both maternal and paternal involvement in rituals are a significant predictor of the child’s treatment response. Results emphasise the need to consider the whole family system, including fathers, in understanding and treating OCD in children.

Psychological well-being of fathers with and without a child with intellectual disability: a population-based study

BACKGROUND

Few studies have explored the well-being of fathers of children with intellectual disability (ID), despite the significant role that they play in their children's lives. The current study compared fathers of children with and without a child with ID on measures of psychological well-being (life satisfaction, work-family balance and general health) and dimensions of parenting (parenting self-efficacy and parent-child closeness) and then examined whether the presence of a child with ID in the family was a significant predictor of paternal well-being when controlling for a number of father (age, education, employment and residency), child (ID status, gender, behavioural and emotional problems) and family (income poverty and number of children in the household) variables.

METHODS

Data were drawn from the third wave of the Millennium Cohort Study, a UK population-representative and cohort study, where the cohort child was 5 years of age; 256 fathers were identified as having a child with ID, with data available for 10 187 fathers without a child with ID. Fathers were compared on the four well-being and parenting outcomes and then multiple regression models were conducted to explore associations between these outcomes and variables identified as potential correlates of well-being.

RESULTS

Initial group comparisons showed that there were differences in the well-being of fathers, with fathers of children with ID reporting poorer life satisfaction and general health. However, these differences were small. Regression analyses showed that child behavioural and emotional problems, living in income poverty and paternal employment were more important than disability status in predicting fathers' well-being.

CONCLUSIONS

These works add to the limited amount of research on fathers using population-representative data. The current findings are consistent with rejecting a general simplistic and negative narrative that raising a child with ID puts fathers at risk of poorer outcomes. However, some fathers, such as those with children with behavioural problems and living in poverty, may require greater support. Future longitudinal research that explores the impact of paternal well-being on the long-term outcomes of children with and without ID is warranted.

Paternal antidepressant use as a negative control for maternal use: assessing familial confounding on gestational length and anxiety traits in offspring

Background

Maternal antidepressant use in pregnancy has been associated with both shorter gestational length and child anxiety. We employed paternal antidepressant use as a negative-control exposure to indirectly assess whether confounding by genetic or shared familial environmental factors associated with depression may explain these associations.

Methods

The study sample came from the population-based Norwegian Mother and Child Cohort Study (MoBa) that recruited participants from 1999 to 2008. We included 70 959 families where the father completed a questionnaire about medication use in the 6 months prior to pregnancy. In 42 511 infants who completed the 3-year follow-up, we computed Z-scores for the anxiety domain of the Child Behavior Checklist. We used linear and logistic regression to assess the association between paternal antidepressant use, gestational age at birth and child anxiety.

Results

Antidepressants were used by 1.1% (n = 755) of fathers. Paternal antidepressant use was not associated with gestational age at birth [β = 0.63 days, 95% confidence interval (CI) –1.56, 0.31] whereas it was positively associated with a child anxiety symptom Z-score and high anxiety symptoms (odds ratio 1.33, 95% CI 0.90, 1.97) in unadjusted analyses. This association was attenuated when controlling for maternal and paternal history of depression and other measured factors (odds ratio 1.14, 95% CI 0.76, 1.69).

Conclusions

These results support the suggested effect of maternal use of antidepressants in pregnancy on shorter gestation; however, they suggest familial confounding could explain the association between maternal use of antidepressants and anxiety traits in the offspring.

Fathers' needs in a surgical neonatal intensive care unit: Assuring the other parent

Objectives

Fathers of infants admitted to Neonatal Intensive Care Unit (NICU) play an important role and have individual needs that are often not recognised. While there is considerable evidence regarding mothers’ needs in the NICU, information about fathers’ is particularly limited. This study identifies the needs of fathers of newborns admitted to NICU for general surgery of major congenital anomalies, and whether health-care professionals meet these needs.

Methods

Forty-eight fathers of infants admitted for surgery between February 2014 and September 2015 were enrolled in a prospective cohort study. Fathers completed the Neonatal Family Needs Inventory comprising 56 items in 5 subscales (Support, Comfort, Information, Proximity, Assurance) at admission and discharge and whether these needs were met; as well as the Social Desirability Scale.

Results

Responses showed Assurance was the most important subscale (M 3.8, SD .26). Having questions answered honestly (M 3.9, SD .20) and knowing staff provide comfort to their infant (M 3.94, SD .24) were fathers’ most important needs. By discharge, fathers expressed a greater importance on being recognised and more involved in their infant’s care. More than 91% indicated their ten most important needs were met by the NICU health-care professionals, with no significant changes at discharge. Clergical visits (M 2.08, SD 1.21) were least important.

Conclusions

Reassurance is a priority for fathers of neonates in a surgical NICU, particularly regarding infant pain management and comfort. It is important that health-care professionals provide reliable, honest information and open-access visiting. Notably, fathers seek greater recognition of their role in the NICU—beyond being the ‘other’ parent.

Factors associated with autism severity among Malaysian children with Autism Spectrum Disorder

BACKGROUND

Children with Autism Spectrum Disorder (ASD) of different levels of symptom severity may exhibit a wide range of behaviours and characteristics. There is a limited nutrition-related study on children with ASD of different severity in Malaysia.

AIMS

This cross-sectional study aims to determine the association between sociodemographic factors, parental factors, and lifestyle factors with autism severity in children with ASD.

METHODS AND PROCEDURES

A total of 224 children with ASD were included in this study. Their mothers completed a self-administered questionnaire on sociodemographic characteristics, autism severity, parenting style, parental feeding practices, parenting stress, child's sleep habits and eating behaviours.

OUTCOMES AND RESULTS

As high as 78.1 % of the children with ASD demonstrated a high level of autism severity. Multiple linear regression showed that father's employment status (B = 6.970, 95 % CI = 3.172, 10.768, p < 0.001) and perceived child weight (B = 3.338, 95 % CI = 1.350, 5.327, p = 0.001) predicted autism severity.

CONCLUSIONS AND IMPLICATIONS

Children with ASD in this study had a high level of autism severity. Regular anthropometric measurements by healthcare professionals should be conducted at the autism intervention centres. It is important to have multidisciplinary collaboration in future research to develop customised guidelines for parents with autistic children.

Paternal ages below or above 35 years old are associated with a different risk of schizophrenia in the offspring

Background

A link between older age of fatherhood and an increased risk of schizophrenia was detected in 1958. Since then, 10 studies attempted to replicate this result with different methods, on samples with different origins, using different age classes. Defining a cut-off at which the risk is significantly increased in the offspring could have an important impact on public health.

Methods

A meta-analysis (Meta Win®) was performed, assessing the mean effect size for each age class, taking into account the difference in age class references, and the study design.

Results

An increased risk is detected when paternal age is below 20 (compared to 20–24), over 35 (compared to below 35), 39 (compared to less than 30), and 54 years old (compared to less than 25). Interestingly, 35 years appears nevertheless to be the lowest cut-off where the OR is always above 1, whatever the age class reference, and the smallest value where offspring of fathers below or above this age have a significantly different risk of schizophrenia.

Conclusion

No threshold can be precisely defined, but convergent elements indicate ages below or above 35 years. Using homogeneous age ranges in future studies could help to clarify a precise threshold.

Increasing condom usage for African-American and hispanic young fathers in a community based intervention

Objectives: This paper investigates a community-based intervention for young fathers, FatherWorks, compared to care-as-usual, 24/7 Dads. We hypothesized that utilizing the FatherWorks intervention (a 15 session parenting intervention, 13 session employment class, paid internship, case management, and access to behavioral health services) will assist in readiness to use condoms and increase condom usage, which may differ by race/ethnicity.Methods: Eligible males (n = 328) were enrolled into a Randomized Control Trial. Participants were 15-24 years old and had fathered one or more children with a female under the age of 21. A survey was taken at baseline and at 15 weeks following the intervention.Results: Analyses of changes indicated that intervention participants improved from the pre-contemplation stage of condom usage towards contemplation, and from preparation to action. The pattern of improvement in the condom use stage of change was different in African-American versus Hispanic participants. Changes in condom use during last intercourse were not significant.Conclusions: Study findings indicate that FatherWorks is successful in increasing the intent to use condoms, with the effect manifesting differently in African-American and Hispanic young fathers. Future work with minority fathers indicates a need for cultural adaptation of the intervention.

Fathers' Dosage in Community-based Programs for Low-income Fathers

Community-based programs for low-income fathers often struggle to get fathers to attend services and activities. This paper reviews the literature examining approaches to measuring dosage in fatherhood programs, rates of dosage, influences on dosage, and the associations between dosage and fathers' outcomes. Studies were limited to programs that conducted randomized control trials, quasi-experimental studies, and one-group pretest/post-test designs. Although most programs report low or moderate dosage levels, some programs achieve high levels of fathers' participation in parenting, coparenting, and economic security classes. Few studies examined dosage in relation to father outcomes. All but one of seven studies reporting effects showed that higher dose levels had positive associations with outcomes such as engagement with children, parenting satisfaction and self-efficacy, perception of coparenting quality, payment of child support, and earnings from work. This paper discusses future directions for studying father's dosage in fatherhood programs.

Breastfeeding in the Community-How Can Partners/Fathers Help? A Systematic Review

Support from partners/fathers and families can play a significant role in a mother’s decision to initiate, continue or cease breastfeeding postnatally. This study systematically reviewed published studies to determine the impact of specific types of partner support on breastfeeding initiation, duration and exclusivity. We used the 2015 Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines for the review. Seven computerized bibliographic databases (Embase, ProQuest Central, Scopus, PsycINFO, Web of Science, MEDLINE/PubMed and CINAHL) were searched. Of a total of 695 articles retrieved from the databases, seven studies met the inclusion criteria and reported on breastfeeding initiation, duration and exclusivity. Four of the seven studies found that partner support in the form of verbal encouragement to new mothers increased breastfeeding duration and exclusivity. Other types of partner supportive actions that led to improved breastfeeding behavior included sensitivity of the partner to the nursing mother’s needs, assistance in preventing and managing breastfeeding difficulties, and helping with household and child care duties. This review showed that specific supportive actions of partners/fathers in the community positively improved breastfeeding practices. To maximise the impact of breastfeeding policies and interventions among new mothers, breastfeeding programmes should consider the involvement of partners/fathers and their specific roles.

Inequalities in Poverty and Income between Single Mothers and Fathers

BACKGROUND

The American family structure has changed in the past few decades due to a rise in the divorce rate and unmarried women with children. Research suggests a salary disparity between men and women, especially for those women after pregnancy. However, these studies were confined to individuals within traditional families, and there is a lack of information of income disparity and poverty status between single mothers and fathers. The current study explored the disparities in single-parent families based on the household income and the poverty status using a set of nationwide censor data.

METHODS

The current study used data from the 2011 and 2013 Panel Study of Income Dynamics (N = 1135). Multivariate regression models were used in the analysis.

RESULTS

The demographic characteristics of the weighted population showed that taxable income, total income, and poverty status were higher for single fathers than mothers, while non-work income was higher for single mothers than fathers. Single mothers were much more likely to be at the crisis category than single fathers. Multivariate analyses showed that gender, age, marital status, years of experience, and geographic region had effects on taxable income, and only gender, marital status, and region had effects on poverty status.

CONCLUSIONS

The results suggest that vulnerable group of single mothers was acknowledged according to income and poverty status. Age, marital status, years of experience, and region would be the critical factors for predicting the income and poverty status for single parenthood.

Maternal vs paternal diabetes: The parental history is different in younger onset versus older onset type 2 diabetes

BACKGROUND

A number of previous studies exploring family history of type 2 diabetes have reported a predominance of maternal diabetes. These studies have not explicitly compared parental history of diabetes across the spectrum of disease onset from youth to later adulthood.

METHODS

Family history data from 11,467 patients with type 2 diabetes were extracted from the RPA Diabetes Centre database. Parental histories of diabetes were compared across a range of age of diagnosis strata (15-<30, 30-<40, 40-<50, 50-<60 and 60-<70 years). For the young-onset group (diagnosed between 15 and 30 years of age), associations between parental history of diabetes and the presence of cardio-metabolic risk factors and diabetic complications were also explored.

RESULTS

For the total cohort and within each age of diagnosis strata, more individuals reported maternal history than paternal history of diabetes. The young-onset group demonstrated the highest prevalence of any parental history of diabetes (60.7%), the highest combined maternal and paternal history (15.8%) and the smallest differential between maternal (25.1%) and paternal (19.7%) history of diabetes. Within the young-onset group, no significant association between parental history and cardio-metabolic risk factors or diabetic complications were identified after a median of 15.0 years of diabetes exposure.

CONCLUSION

Overall, our results demonstrate a consistent maternal excess of diabetes which could be consistent with an underlying epigenetic effect. However, the differential between maternal and paternal history is significantly lower in the young-onset group. Earlier emergence of type 2 diabetes may therefore reflect a different interaction and impact of genetic and environmental factors.

Cohort profile: Aichi regional sub-cohort of the Japan Environment and Children's Study (JECS-A)

PURPOSE

Effects of fetal, perinatal and childhood environment on the health of children at birth and during later life have become a topic of concern. The Aichi regional sub-cohort of the Japan Environment and Children's Study (JECS-A) is an ongoing birth cohort of pregnant women and their children which has been used to provide unique data, as adjunct studies of JECS, on multifaceted potential factors affecting children's health.

PARTICIPANTS

The JECS-A is part of the JECS which follows a total of 100 000 pairs of children and their mothers (fathers' participation is optional) across 15 regions in Japan. In JECS-A, of the 8134 pregnant women living in Ichinomiya City and Nagoya City, Japan, a total of 5721 pregnant women and their 5554 children were included. Sociodemographic and psychological data as well as biological specimens were collected from the pregnant women and their spouses (if available) in the cohort during their pregnancy. Information on children included in the JECS-A was collected from their mothers and includes demographic, behavioural, childcare, psychological and psychiatric data. Urine extracted from disposable diapers and anthropometric data were also obtained from the children.

FINDINGS TO DATE

A similar distribution trend for age at delivery was confirmed between the pregnant women enrolled in the JECS-A and the national statistics of the relevant areas. However, differences in education level and household income were observed. A total of 5502 children remained in the cohort at 18 months after delivery. Compared with the national statistics, the basic demographics of the children in the cohort represented the population in the study areas.

FUTURE PLANS

The enrolled children in the JECS-A will be followed until the age of 13 years. The studies that come from JECS-A will complement JECS and bring novel results with a high level of generalisability.

Do physical activity and screen time mediate the association between European fathers' and their children's weight status? Cross-sectional data from the Feel4Diabetes-study

BACKGROUND

Most research on parenting and childhood obesity and obesity-related behaviours has focused on mothers while fathers have been underrepresented. Yet, recent literature has suggested that fathers uniquely influence their children's lifestyle behaviours, and hence could also affect their weight status, but this has not yet been scientifically proven. Therefore, the present study aimed to determine whether the association between fathers' weight status and their children's weight status is mediated by fathers' and children's movement behaviours (i.e. physical activity (PA) and screen time (ST)).

METHODS

Cross-sectional data of 899 European fathers and their children were analyzed. Fathers/male caregivers (mean age = 43.79 ± 5.92 years, mean BMI = 27.08 ± 3.95) completed a questionnaire assessing their own and their children's (mean age = 8.19 ± 0.99 years, 50.90% boys, mean BMIzscore = 0.44 ± 1.07) movement behaviours. Body Mass Index (BMI, in kg/m2) was calculated based on self-reported (fathers) and objectively measured (children) height and weight. For children, BMI z-scores (SD scores) were calculated to obtain an optimal measure for their weight status. Serial mediation analyses were performed using IBM SPSS 25.0 Statistics for Windows to test whether the association between fathers' BMI and children's BMI is mediated by fathers' PA and children's PA (model 1) and fathers' ST and children's ST (model 2), respectively.

RESULTS

The present study showed a (partial) mediation effect of fathers' PA and children's PA (but not father's ST and children's ST) on the association between fathers' BMI and children's BMI (model for PA; coefficient: 0.001, 95% CI: [0.0001, 0.002]; model for ST; coefficient: 0.001, 95% CI: [0.000, 0.002]). Furthermore, fathers' movement behaviours (PA and ST) were positively associated with their children's movement behaviours (PA and ST) (model for PA, coefficient: 0.281, SE: 0.023, p < 0.001; model for ST, coefficient: 0.345, SE: 0.025, p < 0.001).

CONCLUSIONS

These findings indicate that the influence of fathers on their children's weight status partially occurs through the association between fathers' PA and children's PA (but not their ST). As such, intervening by focusing on PA of fathers but preferably of both members of the father-child dyad (e.g. engaging fathers and their children in co-PA) might be a novel and potentially effective strategy for interventions aiming to prevent childhood overweight and obesity. Longitudinal studies or intervention studies confirming these findings are however warranted to make meaningful recommendations for health intervention and policy.

Household composition and maltreatment allegations in the US: Deconstructing the at-risk single mother family

BACKGROUND

Previous research has demonstrated the association between child maltreatment and household composition, with increased maltreatment risk generally present in single mother households. However, existing research does not fully examine the complexity and configuration of single mother households. In particular, less is known about important variants of single parent family structures, such as grandparents residing in the home, and the extent to which household compositions change across time.

OBJECTIVE

The present study examines rates of maltreatment allegations across various household compositions in a sample of single biological mother households.

PARTICIPANTS AND SETTING

Youth participants (N = 417) were part of the larger multi-site Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) study.

METHODS

Participants completed longitudinal assessments of household composition and maltreatment allegations from ages 4 to 10.

RESULTS

The present study illustrates substantial variability in the rate of maltreatment allegations across different types of single mother household compositions. In particular, the presence of non-relatives, especially unrelated males, demonstrated an increased risk for maltreatment allegations in the home. Conversely, single mother homes with two or more adult relatives, especially grandmothers, were at reduced risk for child maltreatment allegations.

CONCLUSIONS

This study highlights variability in maltreatment allegations among single mother homes, including how maltreatment allegations vary across different household configurations, across child age periods and across different risk levels.

Reciprocal Relations Between Parental Problem Drinking and Children's Sleep: The Role of Socioeconomic Adversity

Reciprocal relations between parental problem drinking (PPD) and children's sleep were examined longitudinally, and socioeconomic status was considered as a moderating variable. At Wave 1, 280 children (Mage  = 10.33) and their parent(s) participated, and 275 families returned 1 year later. At both waves, parent(s) reported on PD and children wore actigraphs that measured established sleep parameters. After controlling for autoregressive effects, fathers' PD predicted reduced sleep duration and efficiency in children over time. Supportive of reciprocal effects, more frequent long wake episodes predicted greater PPD. Fathers' PD was a more robust risk factor for lower than higher income children. Results build on a growing literature that has considered children's sleep in a family context.

The impact of parenthood on risk of registration for alcohol use disorder in married individuals: a Swedish population-based analysis

BACKGROUND

Although being married with children is associated with a reduced rate of alcohol use disorder (AUD), is this finding independent of a marital effect, different in mothers and fathers and potentially causal in effect.

METHODS

Using Cox proportional hazards, we examined, in 1 252 237 married individuals, the association between a resident younger and older child and risk for AUD registration in national medical, criminal, and pharmacy registers. Using logistic regression, we analyzed, in 600 219 parents, within-person models comparing risk for AUD prior to first pregnancy v. with young children. We examined whether risk for AUD in 1302 parents after a first spousal AUD registration was reduced by having a young resident child.

RESULTS

Compared with childless married individuals, resident younger children were associated with a reduced risk for AUD in mothers [hazard ratio (HR) 0.36, 95% confidence interval 0.31-0.41] and fathers (HR 0.66, 0.60-0.73). The reduced risk was attenuated but still significant for older children. Within-person models confirmed the protective effect of young children in mothers [odds ratio (OR) 0.49, 0.30-0.80] but yielded inconclusive results in fathers (OR 0.85, 0.58-1.25). After a first spousal registration for AUD, a resident young child was associated with a substantial reduction in risk for mothers and a weaker marginal effect in fathers.

CONCLUSION

In married individuals, resident children are associated with a reduction in basal risk for AUD which is stronger in mothers than fathers and with younger v. older children. This effect is also evident during high-risk periods. In mothers, our results are consistent with a largely causal effect.

Reduction but not elimination: health inequalities among urban, migrant, and rural children in China-the moderating effect of the fathers' education level

BACKGROUND

Given the urban-rural structure and the increase in rural-to-urban migration, three types of children have emerged in contemporary China: rural, urban, and migrant children. Health disparities among these types of children have caused widespread concern, being the main contributor to health inequalities among children in China. The purpose of this study was to investigate health disparities among these children and the mechanisms underlining them.

METHODS

This research applied multiple linear regression to data obtained from the Chinese Education Panel Survey (CEPS), a national representative survey of 7772 students from 2014 to 2015. Multiple linear regression with interactive terms was used to explore how gender and father's education moderate the degree of health inequalities among the children. 'Height for age Z-scores' (HAZ) was deployed as the indicator of the children's health status, with larger scores indicating better health status.

RESULTS

The findings of the current study were threefold: First, this study found significant health disparities among the three types of children. Urban children are generally the healthiest (M = 1.064), followed by migrant children, (M = 0.779) and rural children (M = 0.612). Second, fathers' education significantly compensates for the heath disparities among the children. Fathers' education has a larger effect in compensating a rural-migrant difference (b = - 0.018, P < 0.05) than a rural-urban difference (b = - 0.016, P < 0.1). Third, the compensating effect of the fathers' education varies by gender. The compensating effect is larger for boys (b = 0.028, P < 0.001) than for girls (b = 0.025, P < 0.01).

CONCLUSIONS

This study found significant health inequalities among urban, migrant, and rural children, which might be shaped by the distinction of urban-rural structure and the process of rural-to-urban migration in contemporary China. Fathers' education also plays an important role in narrowing-but not eliminating-the health inequality between urban and rural children. Furthermore, the compensating effect of fathers' education is higher for boys than for girls, reflecting the patriarchal tradition in China. The currents study suggests that to promote the healthy growth of children, it is necessary to consider the health inequalities among different types of children when developing health-related policies. Factors like family socioeconomic status and gender may likewise play an important role in the implementation of policies.

What to expect when you are expecting: Are health care consumers forward-looking?

A fundamental question in health insurance markets is how do health care consumers dynamically optimize their medical utilization under non-linear insurance contracts? Our paper tests the neoclassical prediction that a fully forward-looking agent only responds to their expected end-of-year price. Our unique identification strategy studies families during the year of childbirth who will likely satisfy their annual deductible, thereby knowing their expected end-of-year price. We find that during the year of a childbirth, fathers increase medical spending by 11% per month after their deductible is satisfied, rejecting the null of fully forward-looking consumers. This behavior cannot be explained by fathers increasing utilization in response to the childbirth itself. Furthermore, this myopia translates to a 21-24% decrease in total annual medical spending, relative to the counterfactual of fully forward-looking behavior, and is concentrated in elective procedures; we find no response in low value or urgent care. Our findings suggest the need for modeling non-linear incentives while accounting for myopic behavior when studying the medical utilization responses to health insurance.

Connection between parent and child religiosity: A meta-analysis examining parent and child gender

Many studies have indicated a relationship between parental and child religiosity, but the strength of the relationship has varied. Moreover, few studies have examined moderators of this relationship, and none have conducted a meta-analysis to determine a concise picture of the association between parent and child religiosity. The current study conducted a meta-analysis to clarify the relationship between parent and child religiosity as well as gender as a possible moderator. Analysis of 30 studies conducted over the past 27 years revealed that the strength of transmission of religiosity from parent to child is dependent on parent and child gender. Overall, effect sizes were strongest for sons, mothers, and the mother-daughter dyad. Thus, these results suggest that gender plays a major role in the connection between parent and child religiosity. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Variation of all-cause and cause-specific mortality with body mass index in one million Swedish parent-son pairs: An instrumental variable analysis

BACKGROUND

High body mass index (BMI) is associated with mortality, but the pervasive problem of confounding and reverse causality in observational studies limits inference about the direction and magnitude of causal effects. We aimed to obtain estimates of the causal association of BMI with all-cause and cause-specific mortality.

METHODS AND FINDINGS

In a record-linked, intergenerational prospective study from the general population of Sweden, we used two-sample instrumental variable (IV) analysis with data from 996,898 fathers (282,407 deaths) and 1,013,083 mothers (153,043 deaths) and their sons followed up from January 1, 1961, until December 31, 2004. Sons' BMI was used as the instrument for parents' BMI to compute hazard ratios (HRs) for risk of mortality per standard deviation (SD) higher parents' BMI. Using offspring exposure as an instrument for parents' exposure is unlikely to be affected by reverse causality (an important source of bias in this context) and reduces confounding. IV analyses supported causal associations between higher BMI and greater risk of all-cause mortality (HR [95% confidence interval (CI)] per SD higher fathers' BMI: 1.29 [1.26-1.31] and mothers' BMI: 1.39 [1.35-1.42]) and overall cancer mortality (HR per SD higher fathers' BMI: 1.20 [1.16-1.24] and mothers' BMI: 1.29 [1.24-1.34]), including 9 site-specific cancers in men (bladder, colorectum, gallbladder, kidney, liver, lung, lymphatic system, pancreas, and stomach) and 11 site-specific cancers in women (gallbladder, kidney, liver, lung, lymphatic system, ovaries, pancreas, stomach, uterus, cervix, and endometrium). There was evidence supporting causal associations between higher BMI in mothers and greater risk of mortality from kidney disease (HR: 2.17 [1.68-2.81]) and lower risk of mortality from suicide (HR: 0.77 [0.65-0.90]). In both sexes, there was evidence supporting causal associations between higher BMI and mortality from cardiovascular diseases (CVDs), stroke, diabetes, and respiratory diseases. We were unable to test the association between sons' and mothers' BMIs (as mothers' data were unavailable) or whether the instrument was independent of unmeasured or residual confounding; however, the associations between parents' mortality and sons' BMI were negligibly influenced by adjustment for available confounders.

CONCLUSIONS

Consistent with previous large-scale meta-analyses and reviews, results supported the causal role of higher BMI in increasing the risk of several common causes of death, including cancers with increasing global incidence. We also found positive effects of BMI on mortality from respiratory disease, prostate cancer, and lung cancer, which has been inconsistently reported in the literature, suggesting that the causal role of higher BMI in mortality from these diseases may be underestimated. Furthermore, we expect different patterns of bias in the current observational and IV analyses; therefore, the similarities between our findings from both methods increases confidence in the results. These findings support efforts to understand the mechanisms underpinning these effects to inform targeted interventions and develop population-based strategies to reduce rising obesity levels for disease prevention.

Prevalence of Portuguese Children Exposed to Secondhand Smoke at Home and in the Car

INTRODUCTION

Children's exposure to secondhand smoke is a cause of serious health problems and infant morbidity. This is the first nationally representative study conducted in Portugal to describe the prevalence of children exposed to secondhand smoke at home and in the car.

MATERIAL AND METHODS

This is a descriptive cross-sectional study with a representative sample of 2396 Portuguese children aged 0 to 9 years old, stratified by age and administrative region NUTS II. Questionnaires were administered between January and September 2016.

RESULTS

Results showed that 6.1% of mothers and 11.2% of fathers reported smoking at home. It was found that 4.5% of mothers and 8.3% of fathers reported smoking in the car. Results also showed that 5.4% of children were double exposed to secondhand smoke at home and in the car. Children whose parents were smokers and had a lower level of education were more exposed to secondhand smoke at home.

DISCUSSION

Children's exposure to secondhand smoke has been decreasing in Portugal. Parental smoking and a low educational level were risk factors for children's exposure to secondhand smoke at home.

CONCLUSION

The main source of children's exposure to secondhand smoke is parental smoking. As such, it is crucial to implement effective measures to control parental smoking. It is necessary to promote smoking cessation among parents and to ban smoking inside the car.

Psychological and parental functioning of widowed fathers: The first two years

Widowed parents play a critical role in promoting family adaptation and facilitating their children's adjustment to the loss of a parent; yet the psychological wellbeing of these parents has received scant attention. In this study we examined depressive symptoms and grief intensity in 252 spousally bereaved men with dependent-age children. Participants learned of the study and completed initial surveys at variable time points during their first 2 years of bereavement. Depressive and grief symptoms remained persistently high, with 45% of the sample exceeding screening thresholds for clinically significant depressive symptoms two years after the death of their spouses. In linear regression models, higher intensity or frequency of depression and grief symptoms were associated with poorer psychological adaptation, lower parenting self-efficacy, and lower parenting satisfaction scores. Relationships between fathers' distress and potentially modifiable end-of-life variables regarding their spouses were examined. Notably, those who reported that their wives were at peace with dying had lower depressive and grief scores at various intervals. Overall, the magnitude and duration of the depressive and grief symptoms suggests that widowed fathers' psychological distress does not quickly abate over the first 2 years of bereavement, which may be attributable to the unique set of bereavement challenges facing widowed parents such as facilitating their children's grief, assuming sole parenting responsibilities, and managing a household on their own. The findings underscore the need to further examine emotional distress in widowed parents and how their wellbeing impacts family functioning.

The Effect of Paid Family Leave on Infant and Parental Health in the United States

California's paid family leave (PFL) policy improved mothers' labor market outcomes, however, the health impacts of this program are less studied. I compare child and parental health of likely eligible households to a series of control groups before and after California's PFL program was implemented. I find improvements in parent-reported overall child health and suggestive improvements in maternal mental health status. Findings also suggest a reduction in asthma and a greater likelihood that parents feel they are coping well with the day-to-day demands of parenting. There are no significant effects on respiratory or food allergies, or father's mental health status. The results are robust to multiple control groups and placebo tests.

Meeting Report on the Conference on Fathers' Role in Children's Weight-Related Behaviors and Outcomes

On September 22, 2017, "Engaging the Forgotten Parent: Conference of Experts on Fathers' Role in Children's Weight-Related Behaviours and Outcomes" brought researchers, students, health professionals, community stakeholders, and knowledge users from Canada, Australia, and the United States together to Toronto, Ontario, for a 1-day gathering focused on furthering scientific understanding of effective strategies to recruit, engage, and retain fathers in family-based obesity research. Furthermore this conference focused on identifying key knowledge gaps and opportunities for collaborative research to further our understanding of fathers' roles in the development of their children's behaviors and weight outcomes. The following four themes emerged from the conference: (1) underrepresentation of fathers in family-based obesity research, (2) fathers' engagement in children's weight-related behaviors and desire to participate in research, (3) best practices in recruiting, engaging, and retaining fathers in research, and (4) key lessons learned from fatherhood research in developmental science.

Preparation for fatherhood: A survey of men's preconception health knowledge and behaviour in England

Methods

A cross-sectional survey of men attending antenatal care with their partners at three London Maternity Units. We assessed level of pregnancy planning using the partner version of the London Measure of Unplanned Pregnancy (LMUP), preconception health behaviours, and whether they had sought information and health professional advice before conception.

Main results

We recruited 573 men (91% response rate). Mean age was 34 years, 86% were in employment or full time education and 66% had a degree. Half were overweight or obese, 16% were still smoking and 79% had consumed alcohol in the three months before conception. Of 250 men answering questions about medication, a third were taking medication with potentially adverse effects on male reproductive health, while 23% reported taking pre-pregnancy vitamins.

46.9% had looked at information about pregnancy from a variety of sources, including online, before their partner became pregnant. Assessed by the LMUP, 74% of pregnancies were planned. Male ‘planners’ were more likely than other men to reduce smoking, reduce alcohol consumption and to eat more healthily in preparation for pregnancy. However, 57% took no action to improve their health.

Significance of the findings

In a sample of relatively educated men accompanying their partners on an antenatal visit, nearly half had made at least one positive health behaviour change before pregnancy, but half were overweight or obese and a third were on medication that could impair male reproductive health. These findings, together with a high prevalence of alcohol consumption and smoking, indicate the need for greater paternal preconception health awareness and care. Innovative ways to promote positive messages about fatherhood, including medication review as part of preconception care, should be evaluated for impact on improving paternal reproductive health and pregnancy and neonatal outcomes.

Transgenerational improvements following child anxiety treatment: An exploratory examination

Background

The present study conducted secondary analyses of a randomized controlled trial to examine the transgenerational relationship between cognitive-behavioral therapy for child Separation Anxiety Disorder (SepAD) and the mental health of parents. Symptoms of anxiety and depression were compared before and after child treatment between parents of children treated for SepAD and parents of healthy children, who did not receive any treatment.

Methods

One hundred and seven children aged 4–14 years with SepAD received one of two cognitive behavioral treatment programs for SepAD (TAFF; TrennungsAngstprogramm Für Familien; English: Separation Anxiety Family Therapy or CC; Coping Cat). Their parents (N = 189; 101 mothers and 88 fathers) were assessed at baseline and post-treatment for symptoms of separation anxiety, general anxiety, and depression. A comparison group of parents (N = 74; 42 mothers and 32 fathers) of 45 children without SepAD, who did not receive any treatment, were also assessed.

Results

Results indicated a significant interaction effect between group and time on mothers’ depression and separation anxiety, indicating that maternal symptoms of depression and separation anxiety improved in the child treatment condition in comparison to mothers of healthy children. There was no significant improvement in parental pathology levels among fathers of children treated for SepAD.

Conclusions

Treatment for child SepAD may have subsequent positive effects on mothers’ own levels of separation anxiety and depression, though the mechanisms are yet unknown. Future studies are needed that test the transgenerational effect of child SepAD treatment on parental mental health as the primary research question.

Paternal depression and child externalizing behaviors: A meta-analysis

Although there is a consensus that maternal depression is strongly related to child externalizing behaviors, research on the association between paternal depression and child externalizing behaviors is mixed. Some research shows that paternal depressive symptoms are positively associated with symptoms of externalizing behaviors, including oppositional-defiant behavior, conduct problems, and overall externalizing behavior, while other studies failed to find an association, or demonstrated a weak or negative association. Given that the most recent meta-analysis on paternal depression and child externalizing behaviors is outdated, an updated meta-analysis is necessary. The present meta-analysis consisted of 52 published and unpublished articles that included a quantitative comparison between paternal depression and child externalizing behaviors. There was a small relationship between symptoms of paternal depression and symptoms of child externalizing behaviors (r = .15; 95% confident interval [.13, .18]; k = 49). Child gender was the only statistically significant moderator, with studies with a larger proportion of boys showing a larger effect (Q = 4.30, p = .038, k = 40); however, one of the articles was identified as an outlier. This moderator was no longer significant after the outlier was removed. Overall, the results suggest that clinicians working with families of fathers with depression should be cognizant of possible co-occurring child externalizing behaviors in the family. Directions for future research and other clinical implications are provided based on the findings of the current study. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

U.S. Mexican parents' use of harsh parenting in the context of neighborhood danger

Family stress model research suggests that parents' exposure to environmental stressors can disrupt key parenting processes. As family stress model scholarship has expanded to include increasingly diverse populations and a wider range of contexts, studies have documented important nuances. One of these nuances concerns U.S. Mexican parents' use of harsh parenting. In the current study, we examined the harshness-as-disruption family stress-model hypothesis, which specifies parental emotional distress as a mediator of positive associations between neighborhood danger and parental harshness. We contrasted this perspective with cultural-developmental perspectives suggesting that harsh parenting may be an important parenting adaptation to dangerous neighborhood environments (harshness-as-adaptation). We tested the harshness-as-disruption hypothesis prospectively, in a sample of U.S. Mexican mothers (N = 749) and fathers (n = 579) with children in the late childhood to early adolescent age-range. Both mothers and fathers demonstrated higher levels of depression symptoms in the face of neighborhood danger. Fathers' harsh parenting, however, was unrelated to neighborhood danger or depressive symptoms. All mothers demonstrated some evidence of the harshness-as-disruption family stress process. For highly familistic mothers, however, harsh parenting may reflect a combination of harshness-as-disruption and harshness-as-adaptation processes. This combined interpretation is consistent with cultural-developmental models highlighting structural inequalities that filter families of color into lower-resourced, more stressful environments, but simultaneously recognizing that families' and communities' adapting cultural systems support parenting responses to such circumstances.

Risk factors for childhood violence and polyvictimization: A cross-country analysis from three regions

Understanding risk factors is important to ending childhood violence and meeting Sustainable Development Goal 16.2. To date, no study has examined patterns of risk factors across countries comprehensively for different types of childhood violence, and there is a dearth of evidence of polyvictimization in lower- and middle-income settings. We analyse risk factors of childhood emotional (EV), physical (PV), sexual violence (SV) and polyvictimization for children aged 13-17 from nationally-representative Violence Against Children Surveys across six countries. We examine risk factors at the community-, household-, and individual- levels for each violence type, stratified by gender using multivariable logistic regression models. Across countries, school enrolment increased violence risk among females and males (three countries), but was protective against violence among females (one country), and among males (three countries). Among females, increasing age was associated with increased risk of SV (five countries) and polyvictimization (three countries); among males this relationship was less salient. Non-residence with a biological father emerged as a risk factor for SV among girls. Few or inconsistent associations were found with other factors, including number of household members, wealth, and urban residence. These results underscore on the one hand, the need for country-specific research on risk factors to inform prevention strategies, as well as increased investment in data collection to provide a more complete and robust basis for evidence generation. High levels of polyvictimization highlight overlapping vulnerabilities children face, and may provide insights for policymakers and practitioners in designing strategies to protect children at greatest risk of abuse.

Is the Brief Child Abuse Potential Inventory (BCAPI) a valid measure of child abuse potential among mothers and fathers of young children in Germany?

BACKGROUND

In order to prevent child abuse, instruments measuring child abuse potential (CAP) need to be appropriate, reliable and valid.

OBJECTIVE

This study aimed to confirm the 6-factor structure of the Brief Child Abuse Potential Inventory (BCAPI) in a German sample of mothers and fathers, and to examine longitudinal predictors of CAP.

PARTICIPANTS AND SETTING

Two waves of data were collected from 197 mothers and 191 fathers of children aged 10-21 months for the "Kinder in Deutschland - KiD 0-3" in-depth study. Families were stratified based on prior self-report data for screening purposes.

METHODS

138 fathers and 147 mothers were included in the analysis (invalid: 25% mothers, 30% fathers). First, validity of reporting was examined. Second, confirmatory factor analysis (CFA) was employed to assess factor structure. Third, internal reliability and criterion validity were examined. Finally, multivariate poisson regressions investigated longitudinal predictors of CAP in mothers.

RESULTS

A previously established six-factor structure was confirmed for mothers but not fathers. CFA failed for fathers due to large numbers of variables with zero variance. For mothers, internal consistency and criterion validity were good. BCAPI score at follow-up was associated with baseline BCAPI score (β = 00.08), stress (β = 0.06), education (β=-0.19) and alcohol use (β = .58).

CONCLUSIONS

Findings confirm the six-factor structure of the BCAPI among German mothers. The clinical use of the BCAPI in fathers is not recommended as it might produce data that are hard to interpret. Further research with fathers is needed to establish if this is due to limitations with this dataset or with the questionnaire.

Game Changers: A Critical Race Theory Analysis of the Economic, Social, and Political Factors Impacting Black Fatherhood and Family Formation

Family has always been one of the strongest institutions in the African American community. However, over the past 30 years, massive changes have occurred within the structure of African American families, resulting in many fathers living apart from their children. Applying the basic tenets of Critical Race Theory (CRT) and Michelle Alexander's notion of Racialized "Game Changing," this article examines the social, political, and economic factors that have worked to undermine normative Black fatherhood involvement and family formation patterns over time. Two of the major arguments-the slavery argument and the cultural argument-offered in the empirical research literature in an attempt to explain the shifts that have occurred within Black families historically are also examined, followed by an in-depth discussion and analysis of factors that underlie the changes in Black family structure and formation over time. The article concludes with a set of policy recommendations for strengthening Black fatherhood and family formation in the 21st century.

An investigation of social class inequalities in general cognitive ability in two British birth cohorts

The 'Flynn effect' describes the substantial and long-standing increase in average cognitive ability test scores, which has been observed in numerous psychological studies. Flynn makes an appeal for researchers to move beyond psychology's standard disciplinary boundaries and to consider sociological contexts, in order to develop a more comprehensive understanding of cognitive inequalities. In this article we respond to this appeal and investigate social class inequalities in general cognitive ability test scores over time. We analyse data from the National Child Development Study (1958) and the British Cohort Study (1970). These two British birth cohorts are suitable nationally representative large-scale data resources for studying inequalities in general cognitive ability. We observe a large parental social class effect, net of parental education and gender in both cohorts. The overall finding is that large social class divisions in cognitive ability can be observed when children are still at primary school, and similar patterns are observed in each cohort. Notably, pupils with fathers at the lower end of the class structure are at a distinct disadvantage. This is a disturbing finding and it is especially important because cognitive ability is known to influence individuals later in the lifecourse.

Testosterone, fathers as providers and caregivers, and child health: Evidence from fisher-farmers in the Republic of the Congo

Males in vertebrate species with biparental care commonly face a life history trade-off between investing in mating versus parenting effort. Among these males, testosterone is frequently elevated during mating and competition and reduced when males help raise offspring. These physiological patterns may be adaptive, increasing males' fitness through investments in young. However, for some species, including humans, indirect parenting often benefits young but can also involve male competition and risk-taking behavior and may be facilitated by elevated testosterone. Despite potential adaptive functions of biological responses to invested fatherhood, few if any mammalian studies have linked fathers' testosterone to offspring outcomes; no studies in humans have. Using data from a small-scale society of fisher-farmers from the Republic of the Congo, we find that fathers who were rated as better providers by their peers had higher testosterone, compared to other fathers in their community. However, children whose fathers had middle-range T compared to fathers with higher or lower levels had better energetic status (higher BMI; greater triceps skinfold thickness). Fathers' indirect and direct care helped to account for these associations between paternal T and children's energetic profiles. Given that human paternal direct and, especially, indirect care are thought to have been important evolutionarily and remain so in many contemporary societies, these findings help to shed light on the facultative nature of human biological responses to fatherhood and the relevance of these factors to children's well-being.

Maternal Health: a Qualitative Study of Male Partners' Participation in Lagos, Nigeria

PURPOSE

Male involvement in maternal healthcare has been described as a key factor to reducing maternal mortality globally. Hence, this study investigated the choice of facility to be used during pregnancy and examined factors that influence male participation in maternal healthcare issues of their spouses as these factors may sometimes influence the choice of health care services for pregnant women.

METHOD

The study was cross-sectional in design; the setting was at Badagry, Lagos, Nigeria. Thirty married men with at least the experience of birth of baby, who consented to participate, were purposively recruited for the study. Data were transcribed and content analysed using free narrative.

RESULT

The results show that orthodox health care, traditional birth attendance (TBA), and faith healing were utilised by the respondents. The majority of the participants identified cost of health care services, economic recession, and their job demand as the reasons for their non-active participation in accompanying their spouses for antenatal clinic visit.

CONCLUSION

However, to increase the level of men's participation in maternal healthcare, especially visiting antenatal clinic with spouses, antenatal services should be free of any monetary charges so as to encourage men to be involved and not look for excuses of financial needs. Utilisation of skilled birth attendance should be reinvigorated.

A longitudinal perspective on boys as victims of childhood sexual abuse in South Africa: Consequences for adult mental health

Childhood sexual abuse of boys was examined in a longitudinal cohort in South Africa, with data on abuse collected at six age points between 11 and 18 years. Potential personal and social vulnerability of male sexual abuse victims was explored and mental health outcomes of sexually abused boys were examined at age 22-23 years. Reports of all sexual activity - touching, oral and penetrative sex - increased with age and sexual coercion decreased with age. Almost all sexual activity at 11 years of age was coerced, with the highest rates of coercion occurring between 13 and14 years of age; 45% of reports of coerced touching were reported at age 14, 41 percent of coerced oral sex at age 13, and 31% of coerced penetrative sex at age 14. Sexual coercion was perpetrated most frequently by similar aged peers, and although gender of the assailant was less often reported, it can be presumed that perpetration is by males. Boys who experienced childhood sexual abuse tended to be smaller (shorter) and from poorer families. No relationships to measured childhood intelligence, pubertal stage, marital status of mother or presence of the father were found. There was no significant association between reports of childhood sexual abuse and mental health in adulthood and when personal and social vulnerabilities were taken into account.

The Development of Latent Dimensions of Psychopathology across Early Childhood: Stability of Dimensions and Moderators of Change

Recent research has described the structure of psychopathology as including one general and multiple specific factors, and this structure has been found in samples across development. However, little work has examined whether this structure is consistent across time, particularly in young children, within the same sample. Further, few studies have examined factors that influence the magnitude of the stability of latent dimensions of psychopathology. In the present study, we examine these issues in a community sample of 545 children assessed at ages 3 and 6. In addition, we explored child temperament, parental history of psychopathology, and parenting behaviors as potential moderators of the longitudinal stability of latent dimensions of psychopathology. We found that the same bifactor model structure identified at age 3 provided an adequate fit to the data at age 6. Further, our model revealed significant homotypic stability of the general, internalizing, and externalizing specific factors. We also found evidence of differentiation of psychopathology over time with the general factor at age 3 predicting the externalizing factor at age 6. However, we failed to identify moderators of the longitudinal associations between psychopathology latent factors. Overall, our results bolster support for the bifactor structure of psychopathology, particularly in early childhood.
