Objectives: To examine the associations between healthy dietary patterns and multimorbidity in Chinese teachers.

Methods: We examined the associations between healthy dietary patterns and multimorbidity among 10781 primary school teachers (39.3±9.4 years old, 74.4% female) in China. Healthy dietary patterns were calculated from a simplified food frequency questionnaire (FFQ), including the Chinese Healthy Eating Index (CHEI), Dietary Approaches to Stop Hypertension (DASH), Alternate Mediterranran Diet (aMed), Healthful Plant-Based Diet Index (hPDI), and Mediterranean-DASH Diet Intervention for Neurodegenerative Delay (MIND) score. Multimorbidity was defined as the co-existence of two or more chronic conditions, including coronary heart disease, stroke, diabetes, hypertension, hyperlipidemia, cancer, depressive symptoms, and anxiety symptoms. Logistic regression models were used to evaluate the corresponding associations.

Results: Among the study participants, 1892 (17.5%) teachers were classified into multimorbidity. Compared with participants in the lowest tertiles of healthy dietary patterns, those in the highest tertiles were associated with lower odds of multimorbidity (Odds Ratio [OR] = 0.75, 95% confidence interval [CI], 0.66, 0.85 for CHEI; OR = 0.81, 95% CI, 0.71, 0.92 for DASH; OR = 0.77, 95% CI, 0.67, 0.89 for aMed; OR = 0.70, 95% CI, 0.62, 0.80 for MIND), whereas no significant associations were observed between hPDI and multimorbidity (OR = 0.92; 95% CI, 0.80, 1.06). The associations were persisted among major subgroups across age, gender, income level, smoking status, alcohol consumption, and physical activity. Among all the chronic conditions, participants with higher adherence to all healthy dietary patterns were associated with lower odds of depressive symptoms and anxiety symptoms.

Conclusions: Our findings support potential beneficial roles of adherence to healthier dietary patterns in maintaining the comprehensive health among Chinese teachers.
