Policy-makers are considering large-scale programs aimed at self-control to improve citizens' health and wealth and reduce crime. Experimental and economic studies suggest such programs could reap benefits. Yet, is self-control important for the health, wealth, and public safety of the population? Following a cohort of 1,000 children from birth to the age(More)
This article reports on the childhood origins and adult outcomes of female versus male antisocial behavior trajectories in the Dunedin longitudinal study. Four antisocial behavior trajectory groups were identified among females and males using general growth mixture modeling and included life-course persistent (LCP), adolescent-onset, childhood-limited, and(More)
CONTEXT A cardinal feature of the DSM-IV diagnostic criteria for conduct disorder is the distinction between childhood- vs adolescent-onset subtypes. Whether such developmental subtypes exist in the population and have different prognoses should be rigorously tested to inform the DSM-V. OBJECTIVES To evaluate the epidemiological validity of childhood- vs(More)
There is a need to collect psychiatric family history information quickly and economically (e.g., for genome-wide studies and primary care practice). We sought to evaluate the validity of family history reports using a brief screening instrument, the Family History Screen (FHS). We assessed the validity of parents' reports of seven psychiatric disorders in(More)
BACKGROUND Chronic exposure to traffic-related air pollution (TRAP) may contribute to premature mortality, but few studies to date have addressed this topic. OBJECTIVES In this study we assessed the association between TRAP and mortality in Toronto, Ontario, Canada. METHODS We collected nitrogen dioxide samples over two seasons using duplicate two-sided(More)
BACKGROUND Variations in air pollution exposure within a community may be associated with asthma prevalence. However, studies conducted to date have produced inconsistent results, possibly due to errors in measurement of the exposures. METHODS A standardized asthma survey was administered to children in grades one and eight in Hamilton, Canada, in 1994-95(More)
BACKGROUND Research into social inequalities in health has tended to focus on low socioeconomic status in adulthood. We aimed to test the hypothesis that children's experience of socioeconomic disadvantage is associated with a wide range of health risk factors and outcomes in adult life. METHODS We studied an unselected cohort of 1000 children (born in(More)
BACKGROUND There is increased interest in assessing the family history of psychiatric disorders for both genetic research and public health screening. It is unclear how best to combine family history reports into an overall score. We compare the predictive validity of different family history scores. METHOD Probands from the Dunedin Study (n=981, 51%(More)
BACKGROUND Breastfeeding is widely advocated to reduce risk of atopy and asthma, but the evidence for such an effect is conflicting. We aimed to assess long-term outcomes of asthma and atopy related to breastfeeding in a New Zealand birth cohort. METHODS Our cohort consisted of 1037 of 1139 children born in Dunedin, New Zealand, between April, 1972, and(More)
