Association Between Maternal Characteristics and the Risk of Isolated Maternal Hypothyroxinemia.

ABSTRACT:

Objective

We aimed to determine the association between maternal characteristics and isolated maternal hypothyroxinemia (IMH).

Methods

Pregnancies registered at Shanghai First Maternity and Infant Hospital between January 2014 and September 2020 were included in this cross-sectional study. IMH was defined as free thyroxine (FT4) levels below the 10th percentile with TSH within the normal reference range. Multivariate logistic regression models were used to identify potential risk factors for IMH, including demographic information, anthropometric measurements and nutritional status.

Results

A total of 54586 singleton pregnancies were included, involving 6084 women with IMH and 48502 euthyroid women. Multivariate logistic regression analyses showed that the variables fo
