Family and Peer Social Capital and Child Behavioral Outcomes in Japan.

BACKGROUND/OBJECTIVES: Child problem behaviors have been linked to immediate and long-term negative outcomes. Research has found that family and peer social capital have a strong influence on child behavioral outcomes. However, most research about social capital and child behavior problems has been conducted in Western contexts. Social capital may influence child behavior problems differently in non-Western sociocultural environments due to different family and peer dynamics. METHODS: Using a sample from the Japan Household Panel Survey and Japan Child Panel Survey (N = 182), we expand this literature on various forms of social capital to the Japanese context with data that were collected between 2009 and 2014. We examine the relationship of family and peer social capital with children internalizing and externalizing problem behaviors using OLS linear regression. RESULTS: Our results differ from what is commonly found in Western contexts. Whereas family and peer social capital are typically associated with both internalizing and externalizing problem behaviors in Western countries, we find that greater family social capital is associated with decreased externalizing problem behaviors but not internalizing problem behaviors in Japan, and peer social capital has no association on either type of problem behaviors. CONCLUSIONS: Our findings emphasize the importance of considering social and cultural contexts when exploring how social capital might encourage prosocial child outcomes.

Family Structure, Family Transitions, and Child Overweight and Obesity: Comparing Australia, the United Kingdom, and the United States.

Growing rates of childhood obesity globally create concern for individuals' health outcomes and demands on health systems. While many policy approaches focus on macro-level interventions, we examine how the type of stability of a family structure might provide opportunities for policy interventions at the micro level. We examine the association between family structure trajectories and childhood overweight and obesity across three Anglophone countries using an expanded set of eight family structure categories that capture biological relationships and instability, along with potential explanatory variables that might vary across family trajectories and provide opportunities for intervention, including access to resources, family stressors, family structure selectivity factors, and obesogenic correlates. We use three datasets that are representative of children born around the year 2000 and aged 11 years old in Australia (n = 3329), the United Kingdom (n = 11,542), and the United States (n = 8837) and nested multivariate multinomial logistic regression models. Our analyses find stronger relationships between child overweight and obesity and family structure trajectories than between child obesity and obesogenic factors. Children in all three countries are sensitive to living with cohabiting parents, although in Australia, this is limited to children whose parents have been cohabiting since before their birth. In the UK and US, parents starting their cohabitation after the child's birth are more likely to have children who experience obesity. Despite a few differences across cross-cultural contexts, most of the relationship between family structures and child overweight or obesity is connected to differences in families' access to resources and by the types of parents who enter into these family structures. These findings suggest policy interventions at the family level that focus on potential parents' education and career prospects and on income support rather than interventions like marriage incentives.

Family Structure and Child Behavior Problems in Australia, the United Kingdom, and the United States.

A large body of literature suggests that children living with two married, biological parents on average have fewer behavior problems than those who do not. What is less clear is why this occurs. Competing theories suggest that resource deficiencies and parental selectivity play a part. We suggest that examining different contexts can help adjudicate among different theoretical explanations as to how family structure relates to child behavior problems. In this paper, we use data from the Growing Up in Australia: Longitudinal Study of Australian Children (LSAC), the UK Millennium Cohort Study (MCS), and the US Early Childhood Longitudinal Study (ECLS-K) to examine the relationship between family structure and child behavior problems. Specifically, we look at how living in several configurations of biological and social parents may relate to child behavior problems. Findings suggest both similarities and differences across the three settings, with explanations in the UK results favoring selectivity theories, US patterns suggesting that there is a unique quality to family structure that can explain outcomes, and the Australian results favoring resource theories.

The relative age effect reversal among the National Hockey League elite.

Like many sports in adolescence, junior hockey is organized by age groups. Typically, players born after December 31st are placed in the subsequent age cohort and as a result, will have an age advantage over those players born closer to the end of the year. While this relative age effect (RAE) has been well-established in junior hockey and other professional sports, the long-term impact of this phenomenon is not well understood. Using roster data on North American National Hockey League (NHL) players from the 2008-2009 season to the 2015-2016 season, we document a RAE reversal-players born in the last quarter of the year (October-December) score more and command higher salaries than those born in the first quarter of the year. This reversal is even more pronounced among the NHL "elite." We find that among players in the 90th percentile of scoring, those born in the last quarter of the year score about 9 more points per season than those born in the first quarter. Likewise, elite players in the 90th percentile of salary who are born in the last quarter of the year earn 51% more pay than players born at the start of the year. Surprisingly, compared to players at the lower end of the performance distribution, the RAE reversal is about three to four times greater among elite players.
