Association of vitamin D with glucose levels in indigenous and mixed population Argentinean boys.

Introduction: There is little information about low vitamin D concentrations in apparently healthy indigenous children in South America.

Objectives: (a) To compare the prevalence of hypovitaminosis D in SAC (San Antonio de los Cobres) versus BA (Buenos Aires) boys and (b) to determine the association of serum vitamin D concentration with age, gender, and risk factors for diabetes.

Methods: This cross-sectional study compares 129 boys from SAC with a 98% indigenous population, versus 116 boys from BA with a mixed population.
