Objective:To evaluate the diet and physical activity of COPD patients and non-COPD patients or normal population,to explore the relationship be-tween diet and COPD,physical activity and COPD,and other factors and COPD.To provide reference for the prevention and treatment of COPD and the guidance of diet and physical activity for clinical COPD patients in Shi-jiazhuang area.Methods:From November 2019 to January 2020 and from September2020 to December 2020,47 COPD patients and 50 non-COPD pa-tients/healthy people who met the inclusion and exclusion criteria were se-lected as case group and control group,respectively,for a case-control study.Questionnaire information was collected by face-to-face interview method.DQI-I scoring method and factor analysis method were used to eval-uate the dietary quality and dietary pattern of the study subjects.and the risk and protective predictors of COPD were determined by logistic regression analysis.Result:1.Compared with the control group,the diet of the elderly in the case group was salty,the diet temperature was warm,and the spicy food was less consumed(P<0.05).2.In addition to the intake of grains,the intake of river fresh food,sea-food,soybean products,dark vegetables,light vegetables,mushrooms and fruits in case group was lower than that in control group(P<0.05).3.The intake of dietary fiber,vitamin A,vitamin B2,vitamin C and cal-cium,overall dietary quality and physical activity level in case group were lower than those in control group(P<0.05).4.Through univariate screening and multivariate analysis,the final re-sults showed that albumin,dark vegetables,mushroom,high vitamin diet,high fat and low sugar diet and physical activity may be the protective factors of COPD(P<0.05).5.There was a significant correlation between dietary pattern and physi-cal activity(P<0.05),and the interaction between dietary pattern and physi-cal activity could jointly reduce the risk of COPD(P<0.05).Conclusion:1.Albumin,dark vegetables,mushroom,high vitamin diet,high fat and low sugar diet and physical activity were independent protective factors for COPD.2.Dietary patterns interact with physical activity,and their combination helps to reduce the risk of COPD together. |
