Vitamin D intake and status in overweight people

Vitamin D deficiency may contribute to the development of osteoporosis and other chronic diseases, such as diabetes and cardiovascular disease. Inadequate vitamin D status is highly prevalent worldwide and is associated with low dietary intake, insufficient sun exposure, aging, and excess weight. The aim of this study was to determine the vitamin D intake and status among overweight people. The participants were adults of both genders with the mean age of 43.5 (n=36). A food frequency questionnaire (FFQ) and 24-hour recall were used to assess the vitamin D intake. Body composition was determined by using the bioelectrical impedance method. Vitamin D status was assessed by determining the concentration of the circulating 25-hydroxyvitamin D [25(OH)D]. The average daily vitamin D intake was 2.51 μg/day, according to the FFQ, and fish was the main source of vitamin D in the diet. The vitamin D intake of the majority of the participants (77.8%) was lower than 20% of the dietary reference intake. The average serum 25(OH)D concentration was 48.4 nmol/L. 88.9% of the participants had an inadequate vitamin D status (<75 nmol/L). A significant inverse association was determined between vitamin D intake and body fat mass.The study has shown a high prevalence of inadequate vitamin D intake and status among overweight people.
