BACKGROUND: There had been a growing evidence of high prevalence of
vitamin D deficiency especially among children which may increase the risk
of many chronic diseases in adulthood.
AIM: Assessment of different lifestyles and dietary behaviour
influencing the level of serum 25-OHD in a group of Egyptian prepubescent
SUBJECTS AND METHODS: Two hundred boys and girls aged from 9 to 11
years were recruited from two primary public schools situated in Giza
governorate in Egypt. A questionnaire was developed to obtain relevant
information related to age, dietary habits, and physical activity. Thorough
clinical examination and measurement of weight and height were performed.
Body mass index was calculated. Serum samples were assayed for 25-hydroxy
vitamin D (25-OHD).
RESULTS: Low serum 25-OHD (< 20 ng/ml) was found in 11.5% of the
whole sample. Mean serum 25-OHD was significantly lower in obese subjects
and in those with low physical activity (p < 0.05). Multiple stepwise linear
regression analysis showed that BMI and physical activity were the main
predictors of serum 25-OHD (P < 0.05).
CONCLUSIONS: Lifestyle factors in terms of physical activity and BMI
may contribute significantly to the optimal vitamin D status of apparently
