High Prevalence of Vitamin D Deficiency and Associated Risk Factors among Employed Women in a Sunny Industrial City.

BACKGROUND

Vitamin D deficiency is a public health concern associated with the pathogenesis of several chronic disorders, particularly in women.

AIM: To evaluate serum vitamin D levels and its deficiency and risk factors among employed women in a sunny industrial city.

METHODS

In this cross-sectional study, serum vitamin D levels, biochemical and hematological factors were assessed in 382 healthy employed women. Demographic information was collected using a standard questionnaire and data was analyzed by SPSS software.

RESULTS

The mean vitamin D serum level was 22 ± 19.8 ng/ml. Prevalence of vitamin D deficiency and insufficiency were 62 % and 12.94 %, respectively. Deficiency was more common among younger subjects (< 29 years old). 23.5 % of subjects had normal and 1.35 % had toxic levels of vitamin D. Maximum serum level was observed in part-time job employees (33 ng/ml), and the lowest in Media and Culture Organizations (15 ng/ml).Vitamin D deficiency was associated with the lack of sunlight exposure at home, and taking anti-hypertensive medications. The common symptoms in deficiency condition were history of hyperlipidemia, depression, weakness, fatigue, finger tingling, leg cramps, and body and muscle pain. Moreover, LDL-cholesterol serum levels were significantly higher in the vitamin D deficiency group, with a prevalence of 40 %.

CONCLUSION

The symptoms of vitamin D deficiency including depression, weakness, fatigue, tingling, leg cramps and body and muscle pain have been observed in more than 90 % after recruitment and treatment. Therefore, for improving the health and productivity of employees, a routine monitoring system for vitamin D and the other factors should be put in place.
