ABSTRACT

The aim of this study is to determine the levels of Vitamin D3 in the province of Russeifa-Jordan and to clarify the effect of demographic variables on Vitamin D3concentration. A cross-sectional study was conducted in the period of April 2016 up to August 2018 in Al- Russeifa, Jordan. Two hundred and seventy-eight subjects were enrolled in this study; 211 females and 67 males, among them 168 nonsmokers and 110 smokers. Vitamin D3 levels ranged from 2 to 36 ng/ml with a mean of 17.37 ± 7.23 ng/ml. Ages ranged from 2 years to 80 years with a mean of 36.3 ± 12.7. Vitamin D3 levels were higher in males than females 19.11 ± 7.399 and 16.82 ± 7.110 ng/ml, respectively.75% of the study population suffered from insufficiency, 20% were obeying sever deficiency levels and only 5% showed sufficient levels of Vit. D3. Negative correlation was demonstrated between smoking, BMI andVit D3serum levels (r= -0.324, p<0.01)(r= - 0.229 p<0.001), respectively. Smoking, age, and BMI are inversely associated with low levels of vitamin D3 in the Jordanian population. Keywords: Vitamin D3, Obesity, Smoking, Age, Gender, Russeifa, Jordan
