Associations of dietary patterns with obesity and weight change for adults aged 18-65 years: Evidence from the China Health and Nutrition Survey (CHNS).

ABSTRACT:

Background

Obesity has become a significant public health problem within China. By observing dietary patterns, an individual's actual dietary habit of nutrients or foods in combination can be identified. We aimed to examine dietary patterns in relation to the risk of obesity (body mass index (BMI) ≥ 25 kg/m2) and weight change (average weight change per five years) within a Chinese cohort.

Methods

We analyzed the data from 6,677 adults aged 18-65 years in the China Health and Nutrition Survey 1997-2015. Westernized, traditional Chinese, and high-starch plant-based dietary patterns were identified by principal components analysis. We estimated relative risks (RRs) and least-squares means (LS-means) with 95% confidence intervals (CIs) using the Cox proportional hazards models
