Are dietary patterns in early childhood associated with alcohol consumption at the age of 17? Analysis of data from the Avon Longitudinal Study of Children and Parents (ALSPAC) prospective cohort study
Abstract Objective To examine the relationship between a posteriori dietary patterns in early childhood and alcohol consumption in adolescence. Design Data was obtained from the Avon Longitudinal Study of Children and Parents (ALSPAC) prospective cohort study. Dietary information was obtained using food frequency questionnaires at ages 3 and 7 years. The association between dietary patterns, derived using Principal Components Analysis (PCA) and the Alcohol Use Disorders Identification Test (AUDIT) scores (to assess harmful intake) and frequency of alcohol consumption at 17 years were examined. Secondary analysis considered sugar intake as a percentage of total energy intake. Setting Women who gave birth between 1 April 1991 and 31 December 1992 in the Avon area in southwest England were eligible for the ALSPAC cohort study. Participants 14,541 pregnancies were enrolled in ALSPAC during its initial recruitment phase. For this analysis, complete data was available for between 3148 and 3520 participants. Results Adherence to the “healthy” dietary pattern at both 3 and 7 years of age was positively associated with consuming more than one alcoholic drink per week at 17 years, whilst adherence to the ‘traditional’ dietary pattern at both ages was protective of harmful alcohol intake at 17. Sugar intake was not associated with either alcohol outcome after adjustment for ethnicity, maternal level of education, parental social class and maternal AUDIT score. Conclusions For the population studied, changes to diet in early childhood are unlikely to have an impact on harmful alcohol use in adolescence given the lack of consistency across the results.
