Early childhood factors influencing health-related quality of life in adolescents at 13 years.

OBJECTIVE To understand the relationship of health-related quality of life (HR-QOL) to early life experience. METHODOLOGY Eight thousand five hundred and fifty-six women enrolled in a prospective study at their first antenatal clinic visit. At 13 years, of 5345 women remaining, a consecutive sample of 901 mother/child pairs provided data on adolescent HR-QOL using the Child Health Questionnaire-Parent Report form (CHQ-PF50) and the Dartmouth COOP Functional Assessment Charts for Adolescents. The CHQ-PF50 yielded physical (PHS) and psychosocial (PSS) summary scores. We examined the relationship between health-related QOL and early childhood predictive variables. RESULTS PHS was related to gestation, maternal health symptoms in pregnancy, maternal anxiety at 6 months, child health and hours of childcare at 5 years (P < 0.05). PSS was related to maternal age at index visit, maternal attitude to pregnancy, maternal satisfaction with care giving and maternal depression at 6 months, and child health and behaviour problems at 5 years (internalizing and social/attentional/thought (SAT) domains) (P < 0.05). Findings from adolescent self-reports were similar. CONCLUSIONS This study has identified a number of early childhood determinants of adolescent HR-QOL. These findings add to evidence of the effects of early adversity on the developmental pathways of children and support the need for effective early intervention.
