Vitamin D deficiency in healthy preadolescents living in Colombia

Abstract

Vitamin D is essential for the body to function. Its deficiency can be associated with bone pathologies as well as other systemic conditions. The prevalence of hypovitaminosisis increasing, in all ages, including children and adolescents. The objective of this study was to evaluate blood levels of vitamin D in Colombian girls, also analyzing diet, physical activity and sun exposure. A descriptive cross-sectional study was carried out with 52 healthy prepubertal girls from Pasto (Colombia), between 7 and 10 yearsold. The levels of albumin, calcium, phosphorus, magnesium, calcitriol (1.25 dihydroxycholecalciferol) and calcidiol (25 hydroxycholecalciferol) were analyzed. Surveys were conducted one a ting habits, physicalactivity and sun exposure. 51.1% of the girls evaluated presented 25-OH-VITD insufficiency and 40% presented deficiency (<20 ng / mL). None of the girls were under nourished or obese, 10% were at risk of low weight (BMI ≤ -1SD and> -2SD), 4% were overweight (≥ + 1DE and 0.05), as well as fiber (p> 0.05) was observed. A vitamin D deficiency is evident in the girls evaluated despite adequate physical activity and sun exposure. In addition, deficient intakes of fiber, calcium, magnesium and vitamin D are observed. Therefore, it would be necessary to ensure the intake and even supplement to avoid health problems in adulthood.
