Abstract
The aim of this study was to assess the effect of nutritional habits and physical activity on bone formation and bone structure in primary school children from two schools at different socioeconomic levels. Sixty children with a mean age of 8.9 ± 1.3 years were included in the study. Thirty children at a high socio economic level from school A were compared with 30 children at a lower level from school B in terms of their bone speed of sound values (SOS). Children from school A were found to have significantly higher values for their length of tibia, span across both arms, height, weight, and head circumference. No association was found between skeletal development and nutrition. Children from school A spent significantly more time at play, while children from school B spent more time on sports (P < 0.001). When total time spent on both sports and play was considered (P < 0.05), school A was ahead of school B. It was also found that SOS values were higher in children who drank milk before sleeping. It can be concluded that with respect to SOS, school A was superior to school B although the difference was not statistically significant.
