Introduction:

Vitamins and micronutrients are essential organic substances in the metabolic processes of living things, and supplementation is only recommended in conditions of nutritional deficits.

Objective:

To determine the prescription patterns of vitamins and supplements in a group of patients enrolled in the Colombian Health System in 2016.

Methodology:

This was a cross-sectional study based on a population database. Vitamin-prescribed patients of both sexes and all ages were selected for 3 consecutive months. A database was designed using the dispensing records. SPSS 23.0 was used for the univariate, bivariate and multivariate analyses. A p-value <0.05 was considered statistically significant.

Results:

In total, 9998 patients receiving vitamin supplementation were identified. A female predominance was observed (n=8341, 83.4%). The mean age was 57.7±18.7 years. The most commonly formulated vitamins and micronutrients were vitamin D (58.0%), calcium (55.0%) and folic acid (25.0%). Overall, 60.8% of patients were prescribed more than one vitamin. The most frequent multiple-nutrient association was between calcium and vitamin D (n=5505); 77.3% received concurrent treatment with other medications to manage comorbidities. The probability of comedication in the multivariate analysis was higher for folic acid (OR:3.10, 95%CI 2.69-3.59), thiamine (OR:2.75, 95%CI:2.15-3.5) and calcium + vitamin D (OR:1.61, 95%CI: 1.42-1.82) and for those individuals older than 65 years (OR:1.24, 95%CI:1.02-1.51).

Conclusions:

Vitamins are widely used in the Colombian population. The results of this study elucidate the patterns of use of these supplements and offer proposed strategies to the future and to evaluate and minimize prescriptions that are potentially inappropriate or of little therapeutic value.
