Abstract

Background Little is known about the effects of overall diet in childhood and intelligence later in life. Methods The current study, based on the Avon Longitudinal Study of Parents and Children, uses data on children’s diet reported by parents in food-frequency questionnaires at 3, 4, 7 and 8.5 years of age. Dietary patterns were identified using principal-components analysis and scores computed at each age. IQ was assessed using the Wechsler Intelligence Scale for Children at 8.5 years. Data on a number of confounders were collected, and complete data were available for 3966 children. Results After adjustment, the ‘processed’ (high fat and sugar content) pattern of diet at 3 years of age was negatively associated with IQ assessed at 8.5 years of ageda 1 SD increase in dietary pattern score was associated with a 1.67 point decrease in IQ (95% CI 2.34 to 1.00; p
