Abstract

 

 

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 children.

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 healthy children.
