Introduction

The prevalence of vitamin D deficiency has been reported to range from 40% to over 70% depending on the study and the population being studied. Not much data is available regarding the prevalence of vitamin D deficiency in the Indian population.

Objective

To quantify the mean vitamin D levels in the Indian population.

Study Design and Methods

This study is a retrospective analysis of the vitamin D levels measured at a major medical center in Hyderabad, India. Vitamin D levels measured as a part of a routine health check were reviewed. A further analysis was done based on gender and geographic location of the population. Here we report the mean and range of the vitamin D levels. A comparison was done with vitamin D levels measured in international patients from Africa having a health check at the same hospital. We assumed a normal vitamin D level to be 30 ng/mL.

Results

In a sample of 65 Indian females the mean vitamin D level was 12.12 ng/mL (range 3-47.5) while in 30 Indian males the level was 11.86 ng/mL (range 3-32.6). Among the Indians living abroad, mean level was 13.6 ng/mL (range 5-20). Among African females the mean vitamin D level was 24.31 ng/mL (range 3.5-50) and among African males the level was 21.62 ng/mL (range 7-40).

 Discussion

The vitamin D levels were found to be lower in Indians with a mean value of 12 ng/mL. In the African population, the mean vitamin D levels were 23 ng/mL. Though India and some of the African countries are at similar latitudes with similar amount of sun light, the vitamin D levels were almost double in the African population compared with Indians. Further investigation into the various factors affecting vitamin D levels in addition to sun light need to be sought.

Conclusion

The mean vitamin D level among Indian females was 12.12 ng/mL and among Indian males 11.86 ng/mL.
