Abstract P321: Healthy Eating Predicts Lower Risk of Major Noncommunicable Diseases in Chinese Adults
Background: Noncommunicable diseases (NCDs) have emerged as a top threat to public health and economic growth worldwide, particularly in developing countries. Adopting healthy dietary patterns is one of the most important modifiable factors for NCD prevention.
Objective: To examine whether higher adherence to the Dietary Guidelines for Chinese is associated with lower risk of developing major NCDs, including coronary heart disease (CHD), stroke, and type 2 diabetes.
Design: A longitudinal analysis of 52,511 men and 64,784 women (40-74 y), who were participants of 2 population-based prospective cohort studies in Shanghai and free of CVD, diabetes, and cancer at baseline (1997-2002).
Method: Habitual diets were assessed at baseline using validated food-frequency questionnaires. Dietary adherence score was estimated according to the 2007 Chinese Food Pagoda. Incident cases of major NCDs were identified via biennial follow-up home visits.
Results: During mean follow-ups of 5.6-10.0 years, we documented self-reported newly diagnoses of CHD, stroke, or diabetes in 3967 men and 6988 women. After adjustment for potential confounders, participants with higher adherence to dietary guidelines showed reduced risks of developing any of these 3 NCDs. Compared with the lowest quintile of adherence score, HRs in the 2nd to 5th quintile were 0.96, 0.90, 0.87, 0.88 (95% CI: 0.83-0.93), P-trend<0.0001. The HR (95% CI) across extreme quintiles was 0.79 (0.63-0.99) for CHD, 0.91 (0.84-0.99) for stroke, and 0.89 (0.82-0.98) for diabetes, all P-trend<0.01. No significant effect modifications were found by sex, education, smoking, obesity, or hypertension. Reduced NCD risk was mainly associated with recommendations on increasing intakes of fruit, dairy, and fish and decreasing salt intake.
Conclusion: Higher adherence to Dietary Guidelines for Chinese, which indicates a healthy dietary pattern, is associated with lower risk of developing cardiovascular diseases and diabetes in middle-aged and older Chinese men and women.
