Fostering relations: first sex and marital timings for children raised by kin and non-kin carers

Kinship fostering is generally preferred to non-kin fostering by policy makers in the U.S. and elsewhere. Researchers and policy makers alike tend to provide several proximate reasons for why this may be, generally neglecting an ultimate evolutionary framework. However, kin selection theory predicts that in the absence of genetically related parents, care from kin will result in the most similar life history outcomes. In low-fertility settings, parents typically favour increased investment in embodied capital and thus delayed reproductive life history strategy. Using archival data from the original Kinsey survey, collected in the U.S. from 1938 to 1963, we used survival analyses to compare the effects of living with kin and non-kin fosterers in childhood on timings of first sex and marriage. Our results support a kin selection hypothesis showing that while fostered children have accelerated life histories compared to children from "intact families", kin fosterers buffer children from early sexual and reproductive behaviors, compared to children cared for by non-kin. © 2014 The Authors

Health Behavior among Lithuania’s Adolescents in Context of European Union

Aim: To compare health behavior patterns of adolescents in Lithuania with health behavior of adolescents in European Union (EU) in 2001/2002. Methods: The study was carried out in conformity with the methodology of Health Behavior in School-aged Children: a World Health Organization cross-national study. Three country representative samples of schoolchildren, aged 11, 13, and 15, were surveyed in 25 EU countries and regions in 2001/2002 school year. The study instrument was a standardized questionnaire that included questions on alcohol consumption, smoking, illegal drugs use, physical activity, and other patterns of health behavior. The rate or mean values of the targeted health behavior of Lithuanian students were assessed and compared to those calculated as an average for the EU countries and regions. Results: We found an early onset of alcohol consumption among Lithuanian boys. Lithuanian boys and girls across all age groups reported being drunk two and more times more often than their peers from other EU member states. Lithuanian 15-year-old boys smoked more often that did their European peers, while girls smoke more rarely. The prevalence of drugs (marihuana group) use among Lithuanian students is relatively low: the prevalence of drug use among 15-year-olds in Lithuania is two times lower than the prevalence in other EU countries and regions (11.2% vs 24.5% for boys and 4.5% vs 18.3% for girls, respectively). Physical activity of Lithuanian adolescents is rather high in comparison with their EU peers, although many students watch television for 4 hours a day. Lithuanian students did not eat sweets often, or drank soft drinks (Coca Cola and other), and they ate fruits and had breakfast every school day. With respect to hygienic habits, approximately only one in 3 boys and every second girl brushed their teeth more than once a day. Conclusions: There are health behavior differences between adolescents in Lithuania and those in other EU countries. The disparities among health behavior of young people in EU countries and regions require Lithuanian and EU health policy to develop initiatives aimed at decreasing health behavior inequalities

Parents' Support and Knowledge of Their Daughters' Lives, and Females' Early Sexual Initiation In Nine European Countries

CONTEXT: The association between early sexual initiation and parenting practices (e.g., support and knowledge) has not been tested in multiple European population-based samples using the same instrument. METHODS: Data provided by females (age 14-16) participating in the 2005-06 Health Behaviors in School-Aged Children (HBSC) survey conducted in Austria, Finland, Greece, Hungary, Iceland, Lithuania, Romania, Spain and Ukraine were used (n=7,466). The dependent variable was early sexual initiation (<16). The main independent variables were maternal and paternal support and knowledge of daily activities. Univariate, bivariate and multivariable analyses were run with standard error corrections and weights. RESULTS: Prevalence of early sexual initiation ranged from a low of 7% (Romania) to a high of 35% (Iceland). In bivariate analyses, maternal and paternal support were significantly negatively related to adolescent females’ early sexual initiation in a majority of countries. In models with demographic controls, parental support was significantly negatively related to early sexual initiation (AOR = 0.80 maternal, 0.74 paternal). After adding parental knowledge, early sexual initiation was no longer associated with parental support, but was significantly negatively related to parental knowledge (AOR = 0.69 maternal and paternal). These patterns held across countries. CONCLUSIONS: Negative associations between parental support and early initiation were largely explained by parental knowledge, suggesting either that knowledge is more important than support or that knowledge mediates the association between support and early initiation. Providers should counsel parents regarding the importance of knowledge of their daughters’ daily lives, which may be enhanced through developing supportive relationships

Social Capital and Vulnerable Urban Youth in Five Global Cities

BACKGROUND: Social capital is essential for the successful development of young people. The current study examines direct measures of social capital in young people in five urban global contexts. METHODS: The Well Being of Adolescents in Vulnerable Environments (WAVE) is a global study of young people aged 15 to 19 years living in disadvantaged, urban settings. Respondent Driven Sampling (RDS) was used to recruit approximately 500 participants from each site. The sample included 2339 young people (mean age 16.7 years; 47.5% female). We examined the associations between social capital in four domains -family, school, peers and neighborhood -and demographic characteristics using gender stratified Ordinary Least Squares regression. We also examined associations between self-reported health and the four social capital domains is minimal. School enrollment was positively associated with social capital for young women in Baltimore, Delhi, and Shanghai: the association was less consistent for young men. The same pattern is true for perceived wealth. Unstable housing was associated with low familial social capital in all groups except young women in Shanghai and young men in Ibadan and Johannesburg. Being raised outside a two-parent family has a widespread, negative association with social capital. Self-reported health had a mainly positive association with social capital with the most consistent association being neighborhood social capital, CONCLUSIONS: Different types of social capital interact with social contexts and gender differently. Strategies that aim to build social capital as part of risk reduction and positive youth development programming need to recognize that social capital enhancement may work differently for different groups and in different settings
