Vitamin D deficiency is common and often under diagnosed. Globally it has been estimated that a billion people might suffer from this deficiency. The objective of this study was to evaluate vitamin status in obese women who visit the clinical nutrition unit at the Military Hospital Mohammed 5th in Rabat.
It is a descriptive study made in Moroccan Military Hospital during one year (June 2014 to June 2015). Population study was women consulting in the clinical unit of nutrition. The study included women over 18 years of age who visited the clinical nutrition unit due to overweight or obesity.Anthropometric measurement (weight and height) were made to calculate Body mass index, and waist circumference was measured. Vitamin D status was made by analysis of 25 OH vitamin D in blood by HPLC. Parathyroid hormone 1-84 was measured in blood by chimiluminescence (ELISA). Furthermore, phosphocalcic status in blood and urine was analysed. SPSS 13.0, was used for statistical analysis.
A total of 479 women were included in the study Their age varied from 18 to 70 years with a mean of 46.53±12.07 years. The average BMI was 34.27 kg/mÂ². (77.6 %) of the women were had vitamin D deficiency including 29 % with severe deficiency while their calcic and phosphorus status was normal.The vitamin D levels is inversely correlated with the BMI and it is statistically significant (p<0.01).
Vitamin D deficiency is highly prevalent in our sample, which should encourage us to envisage a study on a large representative sample of Moroccan population.
