Los países sudamericanos generan programas nacionales para la prevención y tratamiento de la anemia ferropénica; algunos casos son exitosos y otros funcionan limitadamente.

Aim: To evaluate the association between vitamin D deficiency and insulin resistance (IR) or hyperinsulinemia after oral glucose tolerance test (OGTT) in euthyroid non-diabetic individuals. Materials and methods: We carried out an analytical cross-sectional study in euthyroid non-diabetic adults of both sexes, who attended the outpatient service of a private clinic in Lima-Peru during the 2012e2016 period. Participants were categorized in two groups according to their serum vitamin D levels: normal vitamin D levels (serum vitamin D values 20 ng/dL) and vitamin D deficiency (serum vitamin D values < 20 ng/dL). IR was defined as a Homeostasis Model Assessment (HOMA-IR) value 3.8 and hyperinsulinemia after OGTT was defined as a serum insulin value 80mU/mL after 120min of 75-g glucose intake. We elaborated crude and adjusted Poisson regression models to assess the association between serum v...
