The Cox proportional risk regression model was used to analyze the association of baseline Mediterranean diet pattern score and DASH score with the risk of COPD, and the hazard ratio (<i>HR</i>) of the risk and its 95%<i>CI</i> were calculated. Restricted cubic spline was used to analyze the nonlinear association between the two diet scores and the risk of COPD. Stratified analyses were performed according to gender, age, smoking status, etcetera. Sensitivity analyses were conducted by censoring cases diagnosed within one year after the baseline survey or people with a history of malignant tumor disease. <b>Results:</b> As of June 30, 2023, after a median follow-up time of 6.21 years, there were 1 089 (4.0%) new COPD cases with an incidence density of 64.00 per 10 000 person-years. After adjusting for relevant confounders, in the Mediterranean tertile subgroups under diet pattern score, the risk of developing COPD could be reduced by approximately 14% in the intermediate scoring group (<i>HR</i>=0.86, 95%<i>CI</i>: 0.75-0.99) and 15% in the highest scoring group (<i>HR</i>=0.85, 95%<i>CI</i>: 0.72-0.99) compared to the lowest scoring group. The association remained after censoring cases diagnosed within one year of the baseline survey (<i>HR</i>=0.82, 95%<i>CI</i>: 0.70-0.95; <i>HR</i>=0.82, 95%<i>CI</i>: 0.68-0.97) or censoring people with a history of malignant tumor disease (<i>HR</i>=0.84, 95%<i>CI</i>: 0.73-0.97; <i>HR</i>=0.84, 95%<i>CI</i>: 0.71-0.99). No statistical association was found between the DASH score and the risk of COPD. <b>Conclusions:</b> The Mediterranean diet pattern was associated with a lower risk of COPD. Increasing the intake of vegetables, fruits, legumes, and whole grains and decreasing the intake of red meat and others can reduce the risk of COPD. No association was found between the DASH dietary pattern and the risk of COPD in this community population.</p>","PeriodicalId":23968,"journal":{"name":"中华流行病学杂志","volume":"45 12","pages":"1649-1657"},"PeriodicalIF":0.0,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142839762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
