Dietary Intake of Vitamin D and its Relation to an Inflammatory Marker in Obese Women

Abstract

The aim of this study was to evaluate dietary vitamin D intake and its relationship with an inflammation marker in obese women. A cross-sectional study was designed involving obese women (n=44) and women with normal weight (n=44). Anthropometric assessment using weight and height measurements and classification of nutritional status according to body mass index and waist circumference measurement was performed. The intake of vitamin D was assessed using food diaries kept for three days and the Dietpro 5.i program. Determination of C-reactive protein in serum was carried out by turbidimetry measurement. About the results, the mean values ​​of vitamin D intake by obese women were lower than those of the control group and the reference values ​​(p=0.001). The mean C-reactive protein concentrations for obese women and the control group were 2.45±1.72 mg/L and 1.79±0.48 mg/L, respectively. The results of the analysis of correlation between the intake of vitamin D and the inflammatory marker evaluated in this study revealed no significant association. About the conclusion, the obese women evaluated in this study ingested vitamin D at an amount lower than the recommended value. The study does not show any relationship between vitamin D intake and serum C-reactive protein concentrations in obese women evaluated. However, considering the important anti-inflammatory function of vitamin D, it is necessary to deepen knowledge about the impact of this vitamin on obesity.
