Evidence that birth weight is related to bone mass in later life suggests that the intrauterine environment programs the trajectory of subsequent bone development. To explore this hypothesis, we examined whether maternal diet in pregnancy, as assessed by the maternal food frequency questionnaire (FFQ) completed at 32 weeks gestation, is related to bone mass of the child, as measured by total body DXA carried out at age 9 years in the Avon Longitudinal Study of Parents and Children (ALSPAC). Diet records were linked to DXA scan results for the total body and spine sub-region and pooled between pre- and early pubertal boys and girls (n=4,451). Regression analysis was carried out between DXA values and dietary factors following adjustment for social and other confounding factors. Maternal magnesium intake was related to total body BMC (beta=4.9, 7.4-23.1; g) and BMD (beta=4.9, 2.5-7.3; g/cm2 x10(3)) (standardized regression coefficient with 95% confidence limits; P
