Abstract
Abstract: Today, an association between vitamin D deficiency and obesity is well known, but the mechanisms are not clear yet. This study was designed to investigate the effect of body weight on serum vitamin D levels in obese women. This study has been carriedout between 1st of April and 20th of Jun 6262 for obese women (BMI ≥ 30 kg/m2). The obese women diagnosed with vitamin deficiency were aged from 18 to 60 years. The study was performed in government and private clinics of Nutrition and Dietetics for weight loss in Tripoli, Libya. This subjects’ sociodemographic features, anthropometric measurements (height, weight, body mass index (BMI), hip and waist circumference, body composition (body fat mass in kg, body water content in kg) and biochemical parameter measurements calcium (Ca), vitamin D,TG was analyzed through face-to-face interview method. Serum vitamin D level was measured in all obese women by obtaining 2 milliliter blood samples. A standard interview-based questionnaire form was to obtain data on demography. The questions provide details about personal characteristics include age, occupation, income social status, illness, medication, using vitaminD, calcium and another laboratories investigation such as Lipid Profile. A statistically significant relation (p=0.02) was found between serum vitamin D and BMI values in obese women. Also, there was a high relation between serum calcium values and vitamin D values (p= 0.008). This indicates that women diagnosed with vitamin D values from 10 to 20 have the highest level of calcium.
