Objective To investigate the association between maternal TSH, free thyroxine (FT4), and children's body mass index (BMI) trajectories and obesity. Method Based on the Ma'anshan Birth Cohort in China, we repeatedly assayed maternal thyroid functions in 3 trimesters of pregnancy. Children's height and weight were measured 15 times before they were age 6 years. Body fat was assessed when children were aged 6 years. Mplus software was used to fit maternal thyroid hormone trajectories and BMI trajectories. Multivariate logistic regression models and generalized linear models were used in data analysis. Results Low maternal FT4 trajectory was observed to be related to an increased risk of a high children's BMI trajectory and overweight, with an odds ratio and 95% CI of 1.580 (1.169-2.135) and 1.505 (1.064-2.129), respectively. Increased maternal FT4 concentrations in the first, second, and third trimesters were associated with a decreased risk of high children's BMI trajectories and obesity. There was a positive association between low maternal FT4 trajectory and 6-year-old children's body fat ratio with β and 95% CI of 0.983 (0.138-1.829). Furthermore, negative correlations between maternal FT4 concentration in the first, second, and third trimesters of pregnancy and body fat ratio were observed. Conclusions Low maternal FT4 trajectory during pregnancy may predict a high BMI trajectory in children and relate to overweight and high body fat ratio in 6-year-old children. High maternal FT4 concentrations throughout pregnancy may be associated with the decreasing risk of obesity and low body fat ratio in 6-year-old children. [ABSTRACT FROM AUTHOR] |
