The association between dietary patterns before pregnancy and gestational diabetes mellitus: a matched case-control study in China.

ABSTRACT:

Background and objectives

We aimed to explore the relationship between dietary patterns and gestational diabetes mellitus (GDM) during pre-pregnancy six months using principal component analysis (PCA) and the geometric framework for nutrition (GFN).

Methods and study design

The dietary intake of all participants was assessed by a validated semi-quantitative food frequency questionnaire (FFQ). Major dietary patterns were extracted by PCA.

Meanwhile, the relationship between dietary patterns and GDM was visualized using GFN.
