Pre-pregnancy and early pregnancy dietary patterns and gestational diabetes risk among Miao women in China.

ABSTRACT:

Background

Gestational diabetes mellitus (GDM) affects 5-17% of pregnancies globally. However, research on the relationship between dietary patterns and GDM risk is scarce in Asia, especially among ethnic minority groups. This study explored the links between pre-pregnancy and early pregnancy dietary patterns and the risk of GDM in Miao pregnant women in China.

Methods

In this prospective cohort study, we recruited 683 Miao pregnant women and assessed dietary intake using validated food frequency questionnaires covering the year before conception and early pregnancy. Principal component analysis identified major dietary patterns, and multivariable logistic regression models evaluated associations with GDM risk. Restricted cubic spline analysis examined dose-response relation
