Vitamin D status in Armenian women: a stratified cross-sectional cluster analysis
2021
Background: Vitamin D plays a critical role in skeletal development and maintenance, thus sufficiency is an important goal for public health programs. Given the absence of foods fortified in vitamin D in Armenia, we hypothesized that vitamin D insufficiency would be widespread. Methods: We conducted a random modified cluster model survey of vitamin D status of women in the country. We measured 25-hydroxyvitamin D [25(OH)D] by liquid chromatography mass spectrometry in dried blood spot samples and utilized a questionnaire to assess lifestyle factors. Results: In summer, we sampled 1206 participants from 40 communities in Armenia. Mean 25-OH D level among women aged 18–24 was 20 ± 8 ng/mL; aged 25–64 was 21 ± 7 ng/mL; and >65 was 18 ± 8 ng/mL. The country-wide mean of the entire female population was 20 ± 8 ng/mL. A majority (>54%) had 25-OH D levels
