The project (funded by ESRC) examines the role of stressor-induced inflammation in childhood in the aetiology and maintenance of emotional and behavioural problems from childhood to adolescence. The project uses data from the Avon Longitudinal Study of Parents and Children (ALSPAC), a UK study of more than 14,000 pregnant women in 1991-2, the children arising from the pregnancy, and their partners. Adverse life events were measured at both the prenatal and the childhood period. The project explores the complex ways in which events may interact to predict child outcomes, investigates the importance of distinguishing events by type (e.g., dependent vs independent; chronic vs episodic), and examines the role of their perceived impact. Emotional and behavioural problems are measured with the Strengths and Difficulties Questionnaire for ages 4-16 years. In ALSPAC, inflammation in childhood was measured with levels of interleukin 6 and C-reactive protein.
