N2 - Environmental factors, such as nutritional status, physical activity, and drug therapy, can affect bone mineralization. Our objective was to evaluate the relationship between nutritional status, physical activity, and bone mineralization as assessed by multisite quantitative ultrasound technology in children. The study group comprised 67 children, aged 6-17 years (mean, 9.4), attending a primary care clinic. Data on calcium intake and physical activity were collected using a detailed questionnaire. Speed of sound measurements were performed at the distal 1/3 radius and the midshaft tibia using Sunlight Omnisense apparatus. The reported mean calcium intake was 1105 mg/day. There was a significant difference in Z-scores at the radius and tibia between the low-and high-calcium-intake groups (P = 0.004, P = 0.035, respectively). A similar difference was found between the low-and normal-physical-activity groups (P = 0.015, P = 0.036, respectively). In this pilot study, a positive association was found between calcium intake, physical activity, and bone status, as assessed by the quantitative ultrasound technique.
