Objective To investigate the iodine nutritional status of childbearing aged, pregnant and breastfeeding in Fujian Province, and analyze its influencing factors, to provide some scientific guidance for precision iodine supplementation. Methods A total of 1452 women of childbearing age, 2749 pregnant women and 1397 lactating women were selected by a multi-stage stratified random sampling method. A questionnaire survey was conducted. Salt samples were collected from their households to detect salt iodine, and urine samples to detect urinary iodine. The χ2 test and multivariate logistic regression model were used to analyze the demographic characteristics and factors affecting the iodine nutrition level. Results The consumption rates of qualified iodized salt for women of childbearing age, pregnant women and lactating mothers were 89.9%, 92.5% and 93.4%, and the median urinary iodine concentrations were 128.9, 130.2 and 106.0μg/L, respectively. Multivariate logistic regression model analysis showed that women of childbearing age in coastal areas, pregnant women in the second and third trimesters of pregnancy, and coastal areas, and lactating mothers with exclusive breastfeeding, in coastal areas, and consuming non-iodized salt had a higher risk of iodine deficiency ( OR = 1.351; 1.231, 1.389, 1.289; 1.414, 1.313, 2.171, respectively, all P<0.05 ). However, the effects of education level, per capita annual income, urban and rural distribution, and body mass index on the iodine nutrition level among the women were not statistically significant (P>0.05 ). Conclusion The iodine nutrition of women of childbearing age and lactating mothers in Fujian Province is sufficient, while the iodine nutrition of pregnant women is mildly deficient.
