Dietary intake of vitamin D in adult outpatients with different degrees of obesity coming from an urban community

Abstract

The aim of the present study was to investigate in-depth the dietary intake of vitamin D of subjects with different BMI in relation to serum vitamin D status. The survey covered 264 individuals, aged 19 to 60 years. Vitamin D deficiency was found in 33.3% of the participants and 40.2% showed evidence of insufficient vitamin D intake. It was established that the daily average dietary intake of vitamin D among the whole group of subjects was 6.6 μg/day (women – 5.6 μg/day, men – 10.4 μg/day). We found significant correlations between daily average dietary intake of vitamin D and weight, % body fat, fat mass, visceral fat (in women), muscle and fat-free mass, and height-adjusted indices: fat mass index and fat-free mass index, total body water and some metabolic variables (basal insulin and high sensitivity C-reactive protein). The survey revealed that the dietary intake of vitamin D of the respondents was insufficient.
