Association of urinary iodine concentration with gestational diabetes mellitus in U.S. women: A NHANES cross-sectional study (2009-2016).

ABSTRACT: Epidemiological evidence on the association between urinary iodine concentration (UIC) and gestational diabetes mellitus (GDM) remains inconsistent. This study aimed to evaluate the relationship between UIC and GDM in U.S. women. We conducted a cross-sectional analysis using data from 1745 women aged ≥20 years in the 2009 to 2016 the National Health and Nutrition Examination Survey. UIC was measured via inductively coupled plasma dynamic reaction cell mass spectrometry, and GDM status was self-reported. All analyses incorporated the National Health and Nutrition Examination Survey weights, strata, and clusters to ensure national representativeness. Weighted multivariable logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). Model 1 was unadj
