Abstract
BACKGROUND: Vitamin D [25(OH)D] is essential for normal bone development and maintenance. Furthermore, its deficiency has
been associated with obesity, cardiovascular diseases, insulin resistance, autoimmune diseases, and certain cancers.
OBJECTIVE: To determine the incidence of serum 25(OH)D deficiency (<20 ng/ml) among apparently healthy Chilean children
(4–14 years old) from three Chilean geographic areas during May–September 2018.
MATERIALS AND METHODS: Serum 25(OH)D levels were measured by a competitive protein-binding ELISA assay in 1134 children,
and correlations between serum 25(OH)D levels, BMI, and geographic area were calculated. Individuals were grouped according to
their serum 25-hydroxyvitamin D levels (ng/ml): severe deficiency: <5; moderate deficiency: 5–10.9; mild deficiency: 11–20.9;
insufficiency: 21–29.9 and sufficiency: 30–100.
RESULTS: We found 80.4% of children had serum 25(OH)D deficiency, with 1.7% severe, 24.6% moderate, and 54.1% mild. In the
three cities, the percentage of serum 25(OH)D deficit was increased when comparing overweight or obesity with a healthy weight.
Additionally, an interaction effect was observed between geographic area, nutritional status, and serum 25(OH)D levels using the
factorial ANOVA test (p = 0.038). In Antofagasta, there were more overweight children and also a higher percentage of children
with VitD deficiency (<30 ng/ml) compared to Santiago or Concepción.
CONCLUSION: This study revealed a high prevalence of serum 25(OH)D deficiency in children between 4 and 14 years old in Chile
(80.4%) during May–September 2018. Obese and overweight children had the highest prevalence of serum 25(OH)D deficiency.
