Prevalencia de bocio y yodo-deficiencia en embarazadas indígenas de cinco áreas no metropolitanas de Colombia 2019

OBJECTIVE: To assess the prevalence of goiter and iodine deficiency in indigenous pregnant women coming from five non-metropolitan areas in Colombia. MATERIALS AND METHODS: Descriptive cross-sectional cohort study that included pregnant women of any gestational age with no pregnancy-related conditions, seen in community health centers or in their homes. Patients with comorbidities at the time of pregnancy and those who were receiving iodine supplementation were excluded. Simple random sampling was used. The sociodemographic and obstetric characteristics, urinary iodine concentration and the presence of goiter were measured in accordance with the World Health Organization methodology. A descriptive analysis was performed. RESULTS: Of 189 indigenous pregnant women who were candidates to enter the study, 2 declined participation, and 62 had exclusion criteria, and 125 were included in the final analysis. The mean urinary iodine concentration was 184.4 μg/L (min-max: 12.0-390.0). A total of 42 women (33.6%) had iodine deficiency (< 100 μg/L), and goiter (grade 1-2) was found in 43 (34.4%). No grade 3 or 4 goiter was identified. CONCLUSIONS: A high prevalence of goiter and iodine deficiency was found in indigenous pregnant women living in non-metropolitan areas. There is a need to assess maternal and perinatal effects and to implement nutritional interventions.
