Introduction:

vitamin D is a fundamental biomolecule for multiple biological processes in women of childbearing age; it is also one of the most important biomarkers in reproduction.

Objective:

to determine the prevalence of vitamin D deficiency and insufficiency and associated factors in Colombian women between 18 and 49 years of age.

Methodology:

an analytical cross-sectional study; it is a secondary analysis of the Encuesta de Situación Nutricional de Colombia, of 2015. A total of 7181 women between 18 and 49 years old, of childbearing age, who were not pregnant were evaluated. Vitamin D levels were estimated through chemiluminescence immunoassay. Sociodemographic, anthropometric and frequency-of-food-consumption characteristics were evaluated. A general description of the prevalence of vitamin D insufficiency and deficiency was made for each of the variables of interest through absolute and percentage frequencies. To estimate the association between the different characteristics of interest and vitamin D insufficiency and deficiency, multivariate binomial and multinomial logistic regression models were used.

Results:

the prevalence of vitamin D deficiency was 23.8 % and that of insufficiency was 46.8 %; for insufficiency and deficiency the result was 70.6 %. Quartile IV of wealth (OR: 3.21; 95% CI: 2.16-4.77); abdominal obesity (OR: 1.43; IC 95 %: 1.15-1.78), and the Bogotá region (OR: 3.98; 95 % CI: 2.48-6.38) showed an association with vitamin D insufficiency and deficiency.

Conclusion:

a high prevalence of vitamin D insufficiency and deficiency was identified. Therefore, comprehensive interventions involving nutritional and educational components are recommended.
