Dietary patterns during pregnancy and health-related quality of life: The Japan Environment and Children's Study.

ABSTRACT:

Background

Limited research exists on how dietary pattern (DP) influences pregnant women's health-related quality of life (HRQOL). This study aimed to identify DPs in a cohort of 92,448 pregnant Japanese women using fixed data from the Japan Environment and Children's Study (JECS) to investigate the associations of DP with HRQOL.

Methods

During the first trimester, DPs were assessed using the Food Frequency Questionnaire (FFQ), and HRQOL was assessed using the 8-Item Short-Form Health Survey (SF-8). DPs such as Western, Japanese and Unbalanced DP were identified through principal component analysis (PCA). Multivariable logistic model analysis was used to assess the associations between DP and HRQOL as good or poor.
