P12-049 - Dietary patterns in China: a systematic review

Monday, Jun 11
8:00 AM – 3:00 PM

Objectives: Dietary pattern analysis examines the relationship between overall diet and the risk of chronic diseases. Certain dietary pattern (e.g. Mediterranean pattern) or dietary index (e.g. Healthy Eating Index) are associated with reduced risk of heart disease among populations with “westernized” diet. However, an overall picture of the "Chinese dietary pattern" is lacking. Our goal is to explore the key features of major Chinese dietary patterns and variations in these patterns by region.

Methods: Potential studies were identified through a systematic literature search in PubMed, China Academic Journals Database, and the Cochrane Library of Systematic reviews (1990 to October 2017). Search terms included combinations of "diet*", "pattern*" and "China/Chinese" with specific terms including "principal component*", "pca", "factor*", "fa", "cluster*", and "latent class*".

Results: The initial search identified 1035 references. Seventy-nine studies reporting Chinese dietary patterns were identified, of which 58 from mainland China, 8 from Hong Kong, 6 from Singapore, 3 from Taiwan, and other 4 from immigrants overseas. Five major dietary patterns were identified: "traditional whole grain", "traditional refined grain", "western and energy dense", "vegetable and fruit", and "animal (organ) food pattern". There were large variabilities in dietary patterns between regions. Within mainland China, differences in dietary patterns between urban and rural, and between north and south were also observed.

Conclusions: This review appraises the key features of Chinese dietary pattern and provides a baseline reference given the rapid dietary transition in China. Future analysis of the relationships between different Chinese dietary patterns and chronic diseases will help to reveal a healthy Chinese dietary pattern. The proposed healthy Chinese dietary pattern may provide alternative dietary intervention strategies, not limited to Chinese or Asian population, to cope with the increasing global burden of chronic diseases and their modifiable risk factors.
