Prevalence and correlates of vitamin D deficiency in a tropical setting: results from a nationally representative survey

The prevalence of vitamin D deficiency (VDD) may be high in countries with abundant sun exposure year-round, but nationally representative data are lacking.

Using the 2015 Colombian National Nutrition Survey, we defined VDD and low vitamin D (LVD) as serum 25-hydroxyvitamin D [25(OH)D]
