Goiter, iodine bioavailability and intrauterine growth restriction in Indigenous and Afro-descendant pregnant women from six non-metropolitan areas of Colombia (2019-2020)
Bibliographic record
Abstract
INTRODUCTION: Iodine is an essential mineral for fetal growth and brain development. The aim of this research was to evaluate goiter, iodine deficiency and intrauterine growth restriction in pregnant women of minority ethnic groups in Colombia. METHODS: A cross-sectional study was performed in six non-metropolitan areas of Colombia. RESULTS: A total of 318 Indigenous and Afro-descendant pregnant women were invited to participate: 248 (83.2%) Indigenous and 50 (16.8%) Afro-descendants were studied. The mean age was 24 years (range 13-44 years). Of the women, 130 (43.5%) were from the department of Cauca, 72 (24.1%) were from Córdoba, 28 (9.4%) were from Guajira, 26 (8.8%) were from Sierra Nevada de Santa Marta, 22 (7.4%) were from Amazonas, 16 (5.4%) were from Meta and 4 (1.3%) were from the department of Cesar. A total of 244 (81.8%) were illiterate and 291 (97.7%) were of very low socioeconomic level. Goiter was observed in 69 (23.3%) pregnant women (38 (41.7%) from the department of Cauca, 10 (35.7%) from Guajira, 5 (31.2%) from Meta, 6 (27.2%) from Amazonas and 10 (13.8%) from Córdoba). Iodine deficiency (<100 µg/L) was observed in 42 (14.9%) pregnant women (16 (11.6%) mild (50-99 µg/L), 19 (13.8%) moderate (20-49 µg/L) and 7 (5.1%) severe (<20 µg/L)). Being literate was a protective factor for iodine deficiency (odds ratio (OR)=0.19, 95% confidence interval (CI) 0.04-0.84, p=0.016). Being illiterate and iodine deficient was only a risk factor for goiter (OR=6.72, 95%CI 3.9-9.5, p=0.038) in the department of Cauca. CONCLUSION: A high prevalence of goiter, iodine deficiency and intrauterine growth restriction was observed in minority ethnic groups of Colombia. The highest prevalence and risk was observed in the department of Cauca.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
