Dietary patterns and mortality in a Chinese population

Area of Science:

• Nutritional Epidemiology
• Public Health
• Chronic Disease Prevention

Background:

• Limited research exists on dietary patterns and mortality in non-Western populations.
• Investigating dietary habits in diverse ethnic groups is crucial for global health insights.

Purpose of the Study:

• To examine the association between dietary patterns and all-cause and cause-specific mortality.
• To analyze these associations in the unique Singapore Chinese Health Study cohort.

Main Methods:

• Prospective analysis of 52,584 Chinese adults (aged 45-74) from the Singapore Chinese Health Study.
• Identified two major dietary patterns: vegetable-, fruit-, and soy-rich (VFS) and dim sum- and meat-rich (DSM).
• Used Cox proportional hazards regression to assess mortality risks associated with pattern adherence.

Main Results:

• The VFS pattern showed an inverse association with all-cause, cardiovascular disease (CVD), cancer, and respiratory mortality.
• The DSM pattern was positively associated with CVD mortality in the general population.
• In ever-smokers, the DSM pattern was linked to increased all-cause and cancer mortality.

Conclusions:

• Dietary patterns significantly influence mortality risks in Chinese Singaporeans.
• Promoting VFS dietary patterns may reduce mortality.
• The DSM pattern poses risks, particularly for smokers, highlighting the need for targeted dietary recommendations.
