Association between body mass indeks and total body fat on serum vitamin D status in sedentary group of Croatian workers.

Vitamin D deficiency being associated to variety of chronic diseases and increased cardiovascular morbidity and mortality risk related to obesity is of great importance for health prevention especially of working population. The study aim was to assess the association of vitamin D status to obesity in sedentary group of Croatian workers. Study subjects were 105 healthy workers (46% men, 54% women) to which we assessed serum 25-hydroxivitamin D (25(OH)D) concentrations, body mass index (BMI), total body fat (TBF) percentage and dietary habits. The mean serum 25(OH)D concentration was 18.43±11.20ng/l. There were 67% workers with insufficient serum 25(OH)D less than 30ng/l (ID) with mean 15.37±6.76ng/l and mean serum 25(OH)D of 33% workers with adequate serum 25(OH)D (AD) was 36.79±4.39ng/l. We found that ID workers had higher BMI and TBF and their dietary vitamin D was lower compared to AD workers, but with no statistical significance. AD workers had slightly higher dietary intake of vitamin D sources than ID workers. Serum 25(OH)D was negatively and not significantly correlated to BMI (r=-0.46 ; P=0.727) and to TBF (r=-0.09 ; P=0.474) and also we didn’t observed significant difference among ID and AD workers groups between those correlations. With multiple linear regression analysis, BMI and TBF were found to have negative influence on serum 25(OH)D in ID more than in AD workers group as they had lower BMI and TBF values compared to ID workers group, but not statistically significant. Still, the study results are significant for public health obesity and cardiovascular prevention programs that should be more focused on promotion of Mediterranean dietary style, sources of vitamin D and physical activity.
