It is well established that calcium and vitamin D are fundamental for bone growth and development. Though these micronutrients are found in milk products, it is uncertain what relationship milk product intake has with parameters of bone density and body composition in children. The objective was to examine whether intake of milk and alternatives, in children of healthy weights, associates with percent body fat (% BF), bone mineral density (BMD) and bone mineral content (BMC). Healthy participants (BMI z‐score > ‐2 and < 2), 2‐8 y (n= 75) were recruited through daycares in Montreal, Canada. Milk product intake was assessed using a validated 30 day food frequency questionnaire (FFQ). Whole body BMD/BMC, lean mass and fat mass were acquired using DXA array mode (Hologic Discovery QDR series, Apex software version 13.5). Differences among milk product intake tertiles were tested using mixed model ANOVA; data are mean ± SD. The participants were 55% male (41/75), had mean BMI z‐scores of 0.50 + 0.85 and only 3% (2/75) of children did not reach the recommended 2 servings/day of milk and alternatives by Canada's Food Guide. There were no associations among tertiles of either total milk product intake, fluid milk, yogurt or cheese intake and BMD, BMC or % BF (table 1). Age had a significant positive association with BMD and BMC (P < 0.05) and male children had significantly lower % BF (M: 23.8 ± 4.1 F: 28.9 ± 4.9, P < 0.05). These results suggest that in healthy children, most of whom met the recommended 2 servings/day of milk and alternatives, milk product intake may not associate with % BF, BMD or BMC.
