[BDSP. Notice produite par INIST-CNRS EqER0xln. Diffusion soumise à autorisation]. In the present study, we examined the associations of early nutrition with adult lean body mass (LBM) and muscle strength in a birth cohort that was established to assess the long-term impact of a nutrition program. Participants (n=1,446,32% female) were born near Hyderabad, India, in 29 villages from 1987 to 1990, during which time only intervention villages (n=15) had a government program that offered balanced protein-calorie supplementation to pregnant women and children. Participants'LBM and appendicular skeletal muscle mass were measured using dual energy x-ray absorptiometry ; grip strength and information on lifestyle indicators, including diet and physical activity level, were also obtained. Ages (mean=20.3 years) and body mass indexes (weight (kg)/height (m) 2 ; mean=19.5) of participants in 2 groups were similar. Current dietary energy intake was higher in the intervention group. Unadjusted LBM and grip strength were similar in 2 groups. After adjustment for potential confounders, the intervention group had lower LBM (bêta=-0.75 ; P=0.03), appendicular skeletal muscle mass, and grip strength than did controls, but these differences were small in magnitude (
