What maternal educational mobility tells us about the mother's parenting routines, offspring school achievement and intelligence.

BACKGROUND: Educational mobility at the macro-level is a common measure of social inequality. Nonetheless, the correlates of mobility of education at the individual level are less well studied. We evaluated whether educational mobility of the second generation (compared to the first generation level) predicts differences in parenting practices of the second generation and school achievement and intelligence in the third generation. METHODS: Data from a population-based cohort of children in the Netherlands (N = 3547; 49.4% boys) were analyzed. Maternal, grandparental education and family routines, a parenting practice, were reported by the mother. Child school achievement at the end of primary school (∼12 years, with the national Dutch academic test score) and child intelligence (∼6 and 13 years) were measured in a standardized manner. Also, a child genome-wide polygenic score of academic attainment was calculated. To estimate the effect of educational mobility, inverse probability-weighted linear models and Diagonal Reference Models (DRM) were used. RESULTS: Upward maternal educational mobility was associated with better offspring school achievement, higher intelligence, and more family routines if compared to offspring of mothers with no upward mobility. However, mothers did not implement the same level of family routines as similarly educated mothers and grandfathers who already had achieved this educational level. Likewise, children of mothers with upward educational mobility had lower school achievement and intelligence than children of similarly educated mothers with no mobility. Child's genetic potential for education followed a similar association pattern with higher potential in children of upward mobile mothers. CONCLUSION: Policymakers might overlook social inequalities when focused on parental socioeconomic status. Grandparental socioeconomic status, which independently predicts child school achievement, intelligence, and parental family routines, should also be assessed. The child's genetic endowment reflects the propensity for education across generations that partly underlies mobility and some of its effect on the offspring.

Inequalities in Resources for Preschool-Age Children by Parental Education: Evidence from Six Advanced Industrialized Countries.

This paper provides new evidence on inequalities in resources for children age 3-4 by parental education using harmonized data from six advanced industrialized countries-United States, United Kingdom, France, Germany, Netherlands, and Japan-that represent different social welfare regime types. We analyze inequalities in two types of resources for young children-family income, and center-based child care-applying two alternative measures of parental education-highest parental education, and maternal education. We hypothesize that inequalities in resources by parental education will be less pronounced in countries where social policies are designed to be more equalizing. The results provide partial support for this hypothesis: the influence of parental education on resources for children does vary by the social policy context, although not in all cases. We also find that the measurement of parental education matters: income disparities are smaller under a maternal-only definition whereas child care disparities are larger. Moreover, the degree of divergence between the two sets of estimates differs across countries. We provide some of the first systematic evidence about how resources for young children vary depending on parents' education and the extent to which such inequalities are buffered by social policies. We find that while early inequalities are a fact of life in all six countries, the extent of those inequalities varies considerably. Moreover, the results suggest that social policy plays a role in moderating the influence of parental education on resources for children.

Changes in coercive parenting and child externalizing behavior across COVID-19 and the moderating role of parent-child attachment relationship quality.

Research indicates increases in coercive parenting towards children and increases in child externalizing behavior during COVID-19 as compared to the pre-pandemic period. In this preregistered study, we extended previous knowledge by investigating to what extent, and under what conditions, changes in coercive parenting and child externalizing behavior are interrelated. Ninety-five mothers and fathers of children (of age 3 prior to the pandemic) reported on coercive parenting and child externalizing behavior before and during the pandemic, and trained assistants observed the quality of mother-child and father-child attachment relationship prior to the pandemic. We employed latent change score modeling to test the extent to which changes in maternal and paternal coercive parenting and changes in child externalizing behavior across the pre-pandemic period and the onset of the first COVID-19 lockdown are interrelated. Moreover, we tested whether these linkages are moderated by changes in the other parent's coercive parenting and the quality of parent-child attachment relationship. Specifically, we tested the moderation by mother-child (father-child) attachment relationship quality in the relation between changes in mothers' (fathers') coercive parenting and changes in child externalizing behavior. We found that changes in mothers', but not fathers' coercive parenting were positively associated with changes in child externalizing behavior. We found no moderation by changes in the other parent's parenting or by parent-child attachment relationship quality. Our findings provide support for the transactional processes underlying mothers' and children's behavior in the context of non-normative stressful conditions. We recommend incorporating evidence-based (parenting) support for mothers, fathers, and young children in prevention strategies and recovery tools employed during and after future lockdowns and non-normative stressful events.

Within-family linkages between parental monitoring and adolescents externalizing problems with autonomy support as a moderator.

Parents' monitoring efforts are thought to be effective in reducing children's future externalizing problems. Empirical evidence for this claim, however, is limited, as only few studies have unraveled the temporal ordering of these constructs. The present six-wave longitudinal study contributed to the existing literature by examining within-family linkages between monitoring efforts (behavioral control and solicitation) and adolescents' externalizing behaviors while controlling for between-family differences. In addition, it was assessed whether these associations differed when using child versus parent reports, differed for less versus more autonomy-supportive parents, and differed for fathers' versus mothers' monitoring efforts. Longitudinal data (six annual waves) of 497 adolescents (56.9% boys, Mage at T1 = 13.03, SD = 0.46), their mothers (N = 495, Mage at T1 = 44.41, SD = 4.45), and their fathers (N = 446, Mage at T1 = 46.74, SD = 5.10) of the Dutch study Research on Adolescent Development and Relationships (RADAR) were used. Results showed no evidence for the claim that parents' monitoring efforts predict future externalizing problems. In contrast, we found some evidence for the idea that parents' monitoring efforts change in reaction to changes in externalizing problems; when adolescents reported higher levels of externalizing problems than usual in 1 year, this predicted less behavioral control from mothers in the next year. Linkages between monitoring efforts and externalizing problems did not differ between less or more autonomy-supportive parents. Overall, our findings suggest that monitoring efforts are not effective, but also not damaging, in relation to adolescents' externalizing problems.

International differences in gradients in early childhood overweight and obesity: the role of maternal employment and formal childcare attendance.

BACKGROUND: There are significant cross-country differences in socio-economic gradients in later childhood and adulthood overweight/obesity; few studies assess whether this cross-national variation is evident from early childhood. Furthermore, the role of childcare in explaining overweight/obesity gradients might vary across countries, given differences in access, quality and heterogeneity within. Additionally, childcare is linked to parental characteristics such as maternal employment. The interplay between childcare and employment in producing early overweight/obesity gradients has received little attention, and might vary cross-nationally. METHODS: Using harmonized data from six high-quality, large datasets, we explore the variation in gradients in early overweight/obesity (at age 3-4 years old) by parental education across several high-income countries (USA, UK, France, the Netherlands, Germany and Japan). We then assess whether differential formal group care use attenuates some of these gradients, and whether this varies across maternal employment. RESULTS: Gradients in early childhood overweight/obesity by parental education are evident across several developed countries. Countries with higher overall prevalence of early overweight/obesity did not have the largest inequalities across education groups. The contribution of formal group care to producing these gradients varied across countries and across maternal employment status. CONCLUSION: Early childhood inequalities in overweight/obesity are pervasive across developed countries, as noted for older children and adults. However, mechanisms producing these gradients vary across national contexts. Our study shows that, given the right context, quality childcare and maternal employment can successfully support healthy weight trajectories and not contribute (or even reduce) social inequalities in early overweight/obesity.

Do high-income households 'label' family cash benefits? Evidence on family expenditures from Australia.

This study examines family expenditures and how they respond to the provision of family cash transfers, particularly among higher-income families. Naming cash benefits with explicit reference to 'families' or 'children' can nudge households into labelling the extra cash for financial investments in children. Labelling has mainly been assessed among lower-income families. Yet if also higher-income families engage in labelling, there could be unintended consequences on the often stark disparities in child-related investments across the socio-economic divide. Drawing on 2006-2019 data from Household, Income, and Labour Dynamics in Australia (HILDA), the study relies on reforms to Australia's Family Tax Benefit to 'reveal' expenditure responses among higher-income families via an instrumented difference-in-differences design. Higher-income households seem to earmark a family cash transfer for children's clothing but not for children's education fees, while they also assign money to adult clothing. Lower-income households, differently, seem to engage in more clear-cut, child-oriented labelling, at the expense of adult-assignable goods. Family cash transfers can nudge households into spending more money on their children across the socioeconomic divide, but not necessarily homogeneously so. Providing more well-off families with modest transfers might thus have limited perverse effects on inequality in family expenditures.

Longitudinal Linkages Between Parent-Child Discrepancies in Reports on Parental Autonomy Support and Informants' Depressive Symptoms.

Although parent-child discrepancies in reports of parenting are known to be associated with child depressive symptoms, the direction of causality is unknown. To address this knowledge gap, this study contributes to existing literature by examining longitudinal within-family linkages between parent-child discrepancies in their reports on autonomy support and depressive symptoms of children, while also assessing these linkages with parents' depressive symptoms. In addition, this study explored whether these linkages differ for father- versus mother-child discrepancies. Longitudinal data (six annual waves) of 497 adolescents (56.9% boys, Mage at T1 = 13.03, SD = 0.46), their mothers (N = 495), and their fathers (N = 446) of the Dutch study Research on Adolescent Development and Relationships (RADAR) were used. Counter to expectations, the results of a Random Intercept Cross-Lagged Panel Model provided no evidence for within-family cross-lagged effects. Instead, stable differences between families explained linkages; in families where children reported on average higher levels of depressive symptoms, children also reported lower levels of autonomy support relative to their parents. There were no associations between parent-child discrepancies and parents' depressive symptoms. Thus, the findings suggest that depressive symptoms are neither a consequence, nor a predictor of parent-child discrepancies in adolescence. The hypotheses and analytical plan of this study were preregistered in a project on the Open Science Framework.

The role of energy balance related behaviors in socioeconomic inequalities in childhood body mass index: A comparative analysis of Germany, the Netherlands, the United Kingdom, and the United States.

Socioeconomic inequalities in childhood Body Mass Index (BMI) are becoming increasingly more pronounced across the world. Although countries differ in the direction and strength of these inequalities, cross-national comparative research on this topic is rare. This paper draws on harmonized longitudinal cohort data from four wealthy countries-Germany, the Netherlands, the United Kingdom (UK), and the United States (US)-to 1) map cross-country differences in the magnitude of socioeconomic inequalities in childhood BMI, and 2) to examine cross-country differences in the role of three energy-balance-related behaviors-physical activity, screen time, and breakfast consumption-in explaining these inequalities. Children were aged 5-7 at our first timepoint and were followed up at age 8-11. We used data from the German National Educational Panel Study, the Dutch Generation R study, the UK Millennium Cohort Study and the US Early Childhood Longitudinal-Kindergarten Study. All countries revealed significant inequalities in childhood BMI. The US stood out in having the largest inequalities. Overall, inequalities between children with low versus medium educated parents were smaller than those between children with high versus medium educated parents. The role of energy-balance-related behaviors in explaining inequalities in BMI was surprisingly consistent. Across countries, physical activity did not, while screen time and breakfast consumption did play a role. The only exception was that breakfast consumption did not play a role in the US. Cross-country differences emerged in the relative contribution of each behavior in explaining inequalities in BMI: Breakfast consumption was most important in the UK, screen time explained most in Germany and the US, and breakfast consumption and screen time were equally important in the Netherlands. Our findings suggest that what constitutes the most effective policy intervention differs across countries and that these should target both children from medium as well as low educated families.

The intergenerational transmission of educational attainment: A closer look at the (interrelated) roles of paternal involvement and genetic inheritance.

Numerous studies have documented a strong intergenerational transmission of educational attainment. In explaining this transmission, separate fields of research have studied separate mechanisms. To obtain a more complete understanding, the current study integrates insights from the fields of behavioural sciences and genetics and examines the extent to which paternal involvement and children's polygenic score (PGS) are unique underlying mechanisms, correlate with each other, and/or act as important confounders in the intergenerational transmission of fathers' educational attainment. To answer our research questions, we use rich data from The National Longitudinal Study of Adolescent to Adult Health (n = 4,579). Firstly, results from our mediation analyses showed a significant association between fathers' educational attainment and children's educational attainment (0.303). This association is for about 4 per cent accounted for by paternal involvement, whereas a much larger share, 21 per cent, is accounted for by children's education PGS. Secondly, our results showed that these genetic and behavioural factors are significantly correlated with each other (correlations between 0.06 and 0.09). Thirdly, we found support for genetic confounding, as adding children's education PGS to the model reduced the association between paternal involvement and children's educational attainment by 11 per cent. Fourthly, evidence for social confounding was almost negligible (the association between child's education PGS and educational attainment was only reduced by half of a per cent). Our findings highlight the importance of integrating insights and data from multiple disciplines in understanding the mechanisms underlying the intergenerational transmission of inequality, as our study reveals that behavioural and genetic influences overlap, correlate, and confound each other as mechanisms underlying this transmission.

Parent-child personality similarity and differential autonomy support toward siblings.

Since parental differential treatment is related to more adjustment difficulties over and above main effects of parental treatment, it is important to understand under what conditions differential parenting is likely to occur. Using a within-family design, this study focused on between-sibling differences in parent-child personality similarity as a potential predictor of differential autonomy support from fathers and mothers. Longitudinal data (6 annual waves) of 497 target adolescents (56.9% boys, Mage at T1 = 13.03), one of their siblings (N = 416, Mage at T1 = 14.92), their fathers (N = 446, Mage at T1 = 46.74), and their mothers (N = 495, Mage at T1 = 44.41) were used. Parent-child personality similarity was determined based on distinctive profile correlations using the Big Five personality inventory. Structural Equation Modeling showed that the association between sibling differences in mother-child similarity and maternal autonomy support was positive and significant at the between-family level, and not at the within-family level. This means that, in families where one sibling was relatively more similar to the mother, the sibling with closer resemblance to the mother received relatively more autonomy support. No significant effects were found for fathers' differential autonomy support. The present study highlights the importance of considering parent-child similarity in personality for understanding differences between siblings in maternal autonomy support.

The relation between harsh parenting and bullying involvement and the moderating role of child inhibitory control: A population-based study.

Harsh parenting has been linked to children's bullying involvement in three distinct roles: perpetrators, targets (of bullying), and perpetrator-targets. To understand how the same parenting behavior is associated with three different types of bulling involvement, we examined the moderating roles of children's inhibitory control and sex. In addition, we differentiated between mothers' and fathers' harsh parenting. We analyzed multi-informant questionnaire data from 2131 families participating in the Dutch Generation R birth cohort study. When children were three years old, parents reported on their own harsh parenting practices. When children were four, mothers reported on their children's inhibitory control. At child age six, teachers reported on children's bullying involvement. Our results revealed that fathers', and not mothers', harsh parenting increased the odds of being a perpetrator. No moderation effects with children's inhibitory control and sex were found for the likelihood of being a perpetrator. Moderation effects were present for the likelihood of being a target and a perpetrator-target, albeit only with mothers' harsh parenting. Specifically, for boys with lower-level inhibitory control problems, mothers' harsh parenting increased the odds of being a target. In contrast, for boys with higher-level inhibitory control problems, mothers' harsh parenting decreased the odds of being a target. Furthermore, for girls with higher-level inhibitory control problems, mothers' harsh parenting increased the odds of being a perpetrator-target. Overall, our results underscore the importance of differentiating by children's cognitive skills and by parent and child sex to fully understand how harsh parenting and bullying involvement are related.

Interrelated changes in parental stress, parenting, and coparenting across the onset of the COVID-19 pandemic.

Parental stress is a known risk factor for coercive parenting and for lower coparenting quality. In the present study, we examined whether and how changes in parental stress of mothers and fathers from the pre-COVID-19 period (T1) into the height of the first lockdown in the Netherlands (T2) were linked to changes in coercive parenting of mothers and fathers and to changes in coparenting quality. A total of 96 families (46.9% lower or medium and 53.1% higher educational background), with mother, father, and child (53.1% girls; T1: M age = 3.44 years, SD = 0.32; T2: M age = 4.72 years, SD = 0.61) participated. To examine interrelations between parental stress (reported using the Parental Stress Scale), coparenting, and coercive parenting (both reported using the Parenting And Family Adjustment Scales), a multivariate Latent Change Score (LCS) model was employed. Higher initial levels of parental stress were associated with higher initial levels of coercive parenting and lower initial levels of coparenting quality. Similarly, stronger increases in parental stress were associated with stronger increases in coercive parenting and with stronger decreases in coparenting quality. Directions of associations and effect sizes were similar for mothers and fathers in all analyses. The results from the present study indicate the importance of a family systems perspective in prevention and intervention programs. Promotion of systematic family-based preventive and intervention activities by the government might support families during challenging times, as during the novel COVID-19 pandemic.

Parental Job Loss and Early Child Development in the Great Recession.

The study examines whether and why parental job loss may stifle early child development, relying on cohort data from the population of children born in Ireland in 2007-2008 (N = 6,303) and followed around the time of the Great Recession (2008-2013). A novel approach to mediation analysis is deployed, testing expectations from models of family investment and family stress. Parental job loss exacerbates problem behavior at ages 3 and 5 (.05-.08 SDs), via the channels of parental income and maternal negative parenting. By depressing parental income, job loss also hampers children's verbal ability at age 3 (.03 SDs). This is tied to reduced affordability of formal childcare, highlighting a policy lever that might tame the intergenerational toll of job loss.

Longitudinal Linkages Between Father and Mother Autonomy Support and Adolescent Problem Behaviors: Between-Family Differences and Within-Family Effects.

Despite existing evidence on negative associations between parental autonomy support and children's internalizing and externalizing problem behavior, it is difficult to draw conclusions on the effect that parents' autonomy support has on children's problem behavior. This study contributed to the existing literature by unraveling the temporal ordering of parental autonomy support and adolescent problem behavior. In addition, this study examined whether these linkages differed by parent's sex, child sex, and reporter of autonomy support. Data of 497 adolescents (mean age at T1 = 13.03 years, percentage male = 56.9) and their parents from six annual waves of the Dutch study Research on Adolescent Development And Relationships (RADAR) were used. The results showed that stable differences between families explained most linkages between autonomy support and problem behavior. Adolescents with fewer problem behaviors have fathers (both child- and parent-reported) and mothers (only child-reported) who are more autonomy supportive. The results did not differ between boys and girls. The findings suggest that prior studies may have overstated the existence of a causal effect of parental autonomy support on adolescent problem behavior.

Mothers' and fathers' quantitative and qualitative parenting in relation to children's emotional adjustment: A between- and within-family investigation.

This longitudinal study of Australian families (n = 1,884, from age 6-12) examined how fathers' and mothers' quantitative involvement (time spent on childcare) and qualitative involvement (specific parenting behaviors) relate to children's emotional adjustment development. We used dynamic structural equation modeling to disentangle stable between-family differences from within-family fluctuations in qualitative parenting and emotional adjustment, allowing us to investigate the direction of effects between parents and children. Because fathers have been theorized to contribute uniquely to emotional adjustment development, we examined differences between mothers and fathers and the interplay between parent and child sex. We further examined whether between-family differences in quantitative involvement, operationalized as joint (total) and relative (one parent does more) involvement, predict qualitative parenting behaviors and emotional adjustment and moderate the within-family interplay between them. Results revealed between-family correlations of qualitative involvement with emotional adjustment. Evidence for significant average within-family effects was limited to a parenting effect of maternal warmth, and several child effects, which indicated that emotional adjustment evokes changes in parenting. However, parenting effects varied substantially across families, especially for fathers. Between-family differences in quantitative involvement explained some of these differences. When joint quantitative involvement was higher, both parents engaged in more desirable qualitative parenting. When mothers were relatively more involved than fathers, fathers displayed less desirable qualitative parenting, and children were less well adjusted. There was some limited evidence that within-family predictive effects were moderated by quantitative involvement, particularly relative involvement. These findings suggest that all family members benefit from a more equal childcare distribution. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Perceived Quality of the Mother-Adolescent and Father-Adolescent Attachment Relationship and Adolescents' Self-Esteem.

There is consensus in the literature that self-esteem stems from relationships with others. In particular, it is assumed that parents play an important role in the development of children's self-esteem, also in adolescence. Despite the importance of parent-child attachment relationships for adolescents' self-esteem, we know very little about the extent to which fathers and mothers uniquely contribute to adolescents' self-esteem. The current study aims to contribute to acquiring knowledge in this research area in three ways. First, by separating the potential influences of father-child and mother-child attachment relationships on sons' and daughters' self-esteem, the current study is able to investigate the individual contribution of the father-child and mother-child attachment relationship to female and male adolescent's self-esteem. Second, by controlling for changes in the quality of the parental relationship and peer relationships the current study is able to isolate linkages between changes in adolescents' perceived quality of the parent-child attachment relationships and changes in adolescents' self-esteem. Third, by using longitudinal data and solely analyzing within-person variation, the current study is able to rule out stable confounding factors as alternative explanations. Self-reports of 542 adolescents (mean age at T1 = 13.6 years, percentage female = 0.51) from all three waves of the Dutch cohort study Social Development of Adolescents were used. The longitudinal fixed effects models showed that, for both sons and daughters, changes in the perceived quality of the mother-adolescent attachment relationship and changes in the perceived quality of the relationship between adolescents' parents were positively linked with changes in self-esteem. Changes in the perceived quality of the attachment relationship with father were only significantly linked to changes in daughters' self-esteem, not in that of sons. Contrary to the expectations, changes in peer relationships were not associated with changes in adolescents' self-esteem. These findings suggest that even though adolescents may be increasing their time spent with friends and romantic partners, perceived changes in the attachment relationships with fathers and mothers and in the wider family system are highly important for how adolescents think of and judge themselves.

The role of fathers' versus mothers' parenting in emotion-regulation development from mid-late adolescence: Disentangling between-family differences from within-family effects.

This 4-year, multi-informant longitudinal study (N = 480, initial age: 15) investigated the interplay between parental support, behavioral and psychological control, and adolescents' emotion regulation development. We examined reciprocal effects between parents and children, mothers' versus fathers' unique roles in emotion regulation development, and sex differences. Multi-informant data allowed us to compare effects of adolescent-perceived and parent-reported parenting. Finally, innovative analyses allowed us to disentangle between-family differences from within-family predictive processes. Parenting and emotion regulation were associated at the between-family and within-family levels, especially according to adolescent reports. Support primarily played a role between mothers and adolescents, and perceived behavioral control between fathers and adolescents. Sex moderation revealed that support played a more prominent role in mother-daughter than mother-son relationships, and that daughters experienced greater behavioral control. Child effects outnumbered parent effects, which might reflect the increasing equality of adolescent-parent relationships. Finally, adolescent-perceived parenting was a stronger correlate of emotion regulation than parent-reports, suggesting that adolescents' perceptions are a relevant source of information for research and practice. Consistent with the self-determination theory perspective on parenting, emotion regulation flourished when adolescents felt like mothers provided support, and fathers loosened behavioral control. These results are in line with the notion that mother-child relationships are supportive attachment relationships, whereas fathers provide "activation" relationships, challenging adolescents to regulate emotions autonomously by providing less explicit structure.

Physical activity and sport participation: A systematic review of the impact of fatherhood.

Moderate to Vigorous Physical Activity (MVPA), including sport participation, is an important component of a healthy lifestyle. Scholars have devoted considerable attention to understanding the impact of parenthood on MVPA, albeit only for women. As the impact of fatherhood on men's lives is drawing more and more scholarly and societal attention, the aim of the current article is to provide an systematic overview of studies examining the impact of fatherhood on MVPA. A systematic review was conducted in Google Scholar, Web of Science and Web of Knowledge, using (combinations of) the search terms: father(hood), parent(hood), exercise, physical activity, sport and leisure time. This resulted in 54 papers reporting differences in MVPA and/or sport between fathers and childless men or within men that became father, of which 13 were included. Our overview of findings suggested that fathers spent less time on MVPA compared with childless men, but that fathers did not differ from their childless counterparts on the subarea of sport participation. Differences in time spent on MVPA were strongest between childless men and fathers with young children (< 6 yrs). Our systematic review revealed that fathers spent less time on MVPA compared to childless men, especially when they had young children. Interestingly, linkages between parental status and the subarea of sport participation were not found, which suggests that fathers cut back on other areas of MVPA. Given the impact of MVPA on a healthy lifestyle, future research in this field is warranted.

Changes in union status during the transition to parenthood in eleven European countries, 1970s to early 2000s.

Couples who have children are increasingly likely to have lived together without being married at some point in their relationship. Some couples begin their unions with cohabitation and marry before first conception, some marry during pregnancy or directly after the first birth, while others remain unmarried 3 years after the first birth. Using union and fertility histories since the 1970s for eleven countries, we examine whether women who have children in unions marry, and if so, at what stage in family formation. We also examine whether women who conceive when cohabiting are more likely to marry or separate. We find that patterns of union formation and childbearing develop along different trajectories across countries. In all countries, however, less than 40 per cent of women remained in cohabitation up to 3 years after the first birth, suggesting that marriage remains the predominant institution for raising children.

Parity and men's mortality risks.

BACKGROUND: Most studies on associations between parity and mortality focus on women, and find a negative correlation or U-shaped pattern. If and why having children is associated with mortality among men is less clear. Our objective was to improve understanding of the association between men's parity and mortality, and to investigate mechanisms potentially underlying this association. METHODS: Analysis of baseline data (1991) from a prospective cohort study (the GLOBE study) with almost 17 years mortality follow-up among 4965 men, aged ≥45 years. Cox proportional hazard hierarchical regression models were used to link parity to mortality and to explore the role of socio-economic position (SEP), health behaviours and partner status. RESULTS: Fathers of two or three children [hazard rate ratio (HR) 0.85; 95% confidence interval (95% CI) 0.74-0.99] and especially fathers of four or more children (HR 0.81; 95% CI 0.69-0.95) had lower mortality risks compared with childless men. However, this association attenuated to non-significance after adding SEP, health behaviours and partner status to the model. CONCLUSIONS: Our findings suggest that childless men have higher mortality risks in comparison with men who have fathered two or more children.
