Vitamin D was studied in regards to its possible impact on body mass reduction and metabolic changes in adults and children with obesity yet there were no studies assessing the impact of vitamin D supplementation during a weight management program in children and adolescence. The aim of our study was to assess the influence of 26 weeks of vitamin D supplementation in overweight and obese children undergoing an integrated 12-months' long weight loss program on body mass reduction, body composition and bone mineral density. A double-blind randomized placebo-controlled trial. Vitamin D deficient patients (<30 ng/ml level of vitamin D) aged 6-14, participating in multidisciplinary weight management program were randomly allocated to receiving vitamin D (1200 IU) or placebo for the first 26 weeks of the intervention. Out of the 152 qualified patients, 109 (72%) completed a full cycle of four visits scheduled in the program. There were no difference in the level of BMI (body mass index) change - both raw BMI and BMI centiles. Although the reduction of BMI centiles was greater in the vitamin D vs. placebo group (-4.28 ± 8.43 vs. -2.53 ± 6.10) the difference was not statistically significant (p = 0.319). Similarly the reduction in fat mass-assessed both using bioimpedance and DEXa was achieved, yet the differences between the groups were not statistically significant. Our study ads substantial results to support the thesis on no effect of vitamin D supplementation on body weight reduction in children and adolescents with vitamin D insufficiency undergoing a weight management program.
