Abstract:
This study was conducted to determine if either calcium intake or physical activity is related to bone mineral status in children and youth aged 10 to 15 years. Subjects (n = 30) with high, medium, and low bone mineral status were selected based on radius bone mineral index measurements from a sample of 108 subjects measured 9 to 12 months previously. Calcium intake was estimated from two 24-hour recalls and a food frequency questionnaire. Assessment of activity level was conducted by questionnaire. Single photon absorptiometry was used to obtain bone mineral content (g/cm) and bone mineral index (g/cm²) measurements for the radius and ulna at the midshaft and distal sites. Calcium intake and activity level were found to be similar among the bone mineral index groups. Using regression analysis, however, calcium intake was shown to be significantly related to midshaft ulna bone mineral index and activity level (sports participation) was found to be significantly related to distal ulna bone mineral index.
