A relationship between childhood exposure to violence and the perpetration of sexual aggression in young adulthood has recently been established. In addition to replicating the relationship between these variables, this study also examined parenting style as a factor that may moderate this correlation. In this study, 903 college students completed an online survey assessing childhood exposure to violence, sexual aggression, and parenting variables. Childhood exposure to violence was correlated to the perpetration of sexual aggression in young adulthood. Also, the way in which individuals believed they were parented during childhood moderated the relationship between exposure to violence and sexual aggression. Both the optimal and affectionate constraint parenting styles significantly reduced correlations between exposure to violence and sexual aggression.

Aggression between couples is a pervasive social problem throughout various life stages, including the transition to parenthood. Partner aggression during this life stage is particularly problematic given the possible negative effects it has on children’s development, including the possibility of the intergenerational transmission of aggression. However, not all children who are exposed to parental aggression become perpetrators of aggression. The present study used an initial community sample of 98 pregnant couples that were followed for two years. It was found that over 90% of children were exposed to parental psychological aggression, and approximately a third of children were exposed to parental physical aggression. Exposure to psychological aggression was related to externalizing symptoms for girls, and exposure to physical aggression was related to select internalizing symptoms for boys and girls. Parenting behaviours moderated the link between exposure to parental psychological aggression and childhood aggressive behaviour. Surprisingly, although consistent with a strict interpretation of the social learning theory, high quality parenting behaviours were related to more childhood aggression within the context of an aggressive household. The findings of this study can be applied to prevention and treatment programs focused on curtailing childhood exposure to partner aggression and the intergenerational transmission of aggression. / Graduate / 0622 / 0620 / 0384

This thesis examines the relationship between childhood exposure to air pollution and long-term health. The research is based on an earlier study (1978-1986) that examined the relationship between exposure to air quality and respiratory health for a cohort of elementary school-aged children (n=3,202). These children resided in four distinct neighbourhoods in Hamilton, Ontario, which exhibited significant gradients in air pollution levels. Informed by the Life Course Health Development model, a survey was developed and administered on a reconstructed cohort (n = 395). The following objectives were addressed: 1) to determine the current health status of the reconstructed cohort; 2) to assess the potential relationship between childhood exposure to air pollution and adult respiratory health; and, 3) to explore factors mediating this relationship. Data was collected for a range of variables including residential and occupational histories, socio-demographic variables, and health outcomes. The dataset was merged with data from childhood on respiratory health, exposure to air pollution, and socio-demographic variables. Results indicate that a relatively high percentage of respondents had asthma in childhood (11%) compared to the original cohort (5.5%). In addition, prevalence rates of most health outcomes were higher than those of the Canadian population. Despite the gradient in air pollution levels, there were no significant differences in health status across neighborhoods. However, results of bi-variate and multi-variate analysis indicate possible significant associations between childhood exposure to S02 and hospital visits for asthma, asthma incidence in adulthood, and ever being diagnosed with asthma for females. For males, results suggest that childhood exposure to S02 is not linked to respiratory health. Factors related to the macro and micro environments also play significant roles in long-term health. This thesis made significant contributions to knowledge by suggesting that childhood exposure to S02 may impact long-term respiratory health for females, and may be linked to inflammatory diseases. / Thesis / Doctor of Philosophy (PhD)

Yes / This paper highlights the scarring effects of early life exposure to civil war, by examining the impact of exposure to conflict in childhood on the incidence of domestic violence in adulthood among married women. To estimate these effects, we use a difference-in-differences model which exploits variation in exposure to Nigeria’s 30-month-long civil war by year of birth and ethnicity. Our results, based on the 2008 Nigerian Demographic Health Survey, show that women exposed to the war during childhood are more likely to be victims of domestic violence in adulthood compared to those not exposed to the war, with larger effects observed for those exposed at younger ages. Additionally, we explore the mechanisms through which exposure to civil war might affect domestic violence, and find some support for both the normalisation of violence and weakened bargaining power hypotheses. Understanding the root causes of domestic violence is important given the high prevalence in developing countries and the deleterious consequences for women and their children.
