Abstract：Objective To analyze the relationship between dietary patterns and overweight/obesity among adult residents aged 18 to 64 years in Yuelu District of Changsha City, and to provide a reference basis for conducting targeted nutrition education and nutrition interventions. Methods We analyzed the general information about the respondents in the Food Consumption Survey of Chinese Residents in 2020, data regarding the frequency of intake of food products in the past month, data concerning dining out in the past week, diet data and height and weight data. χ2 test was used to compare the differences in the overweight/obesity rates in different demographic characteristics and dietary habits. Factor analysis was employed to establish dietary patterns, and multivariate logistic regression was applied to analyzing the relationship between dietary patterns and overweight/obesity. Results A total of 278 residents were enrolled in the survey and analysis, with an average age of (41.03±12.01) years, 89 (32.01%) cases of overweight and 11 (3.96%) cases of obesity. Six dietary patterns were extracted from the factor analysis, including traditional dietary mode, animal and plant protein mode, dairy products, fruits and vegetables mode, snack mode, western dietary mode and fast food and drinking mode. The results of multivariate logistic regression analysis revealed that, after adjusting for the confounding factors, fruits and dairy products mode(OR=0.242, 95%CI:0.096-0.607, P=0.003), and fast food and drinking mode(OR=0.345, 95%CI:0.134-0.889, P=0.028) were inversely associated with the risk of developing overweight/obesity in adult residents, whereas snack mode(OR=2.894, 95%CI:1.092-7.670, P=0.033) was positively correlated with the risk of developing overweight/obesity in adult residents. Conclusion Dietary patterns of residents aged 18-64 years in Yuelu District can affect the occurrence of overweight/obesity; and hence, it is necessary to strengthen the publicity and education about dietary nutrition, and conduct reasonable dietary guidance and interventions for adult residents with overweight/obesity.
