Resumen

Objective. To determine the plasmatic levels of vitamin D and its relationship with the occupation, origin and the values of calcium, leukocytes, hemoglobin and platelets in older adults of Metropolitan Lima. Methods Observational descriptive cross-sectional study, 100 older adults of either sex from Metropolitan Lima participated, they were recruited during the winter-spring seasons of 2022, vitamin D levels were categorised as sufficient, insufficient, and deficient, serum vitamin D concentrations were measured by radioimmunoassay. The relationship of variables was established with the Spearman correlation coefficient and logistic regression. Results. The mean age was 69.6 years, 71% were women, the mean vitamin D concentration was 36.56 ng/ml, 13% had deficient levels, 32% were insufficient and 53% sufficient. By sex, 77.7% of those with deficient/insufficient levels were women. In the bivariate analysis, there was no correlation between vitamin D values with calcium, hemoglobin, leukocytes and platelets; those who came from districts with lower temperatures had a 2.25 times greater risk of having insufficient/deficient levels of vitamin D. Conclusions. 45% of older adults had deficient/ insufficient levels of vitamin D, more frequent in women and those coming from districts with lower average temperatures.
