【摘要】：目的了解南京城区居民的膳食模式及其相关影响因素。方法采用多阶段分层整群随机抽样方法,对南京市2个城区7个社区里年满30周岁的常住居民进行调查。采用专门设计的食物频数量表,应用探索性因子分析方法建立膳食模式。结果因子分析提取5种膳食模式:调味品模式、动植物蛋白模式、传统健康模式、甜食模式和饮酒、饮料模式。传统健康模式类似于精明膳食模式;甜食,饮酒、饮料模式类似于西方膳食模式。经多因素Logistic回归分析显示,传统健康模式与男性、高龄、高社会经济状况(socio-economic status,SES)、健康生活方式呈正关联,与体重指数、腰围呈负关联;而甜食模式和饮酒、饮料模式与低龄、不健康生活方式、体重指数、腰围呈正关联(均有P0.05)。结论膳食模式受社会人口统计学及生活方式等多种因素影响。高SES、健康生活方式人群易采取健康膳食模式。应加强公众教育,倡导平衡膳食,尤其针对低SES和不健康生活方式的人群。
[Abstract]:Objective to investigate the dietary patterns and related factors of urban residents in Nanjing. Methods Multi-stage stratified cluster random sampling was used to investigate the residents aged 30 years or older in 7 communities in 2 urban areas of Nanjing. A specially designed food frequency scale was used to establish a dietary pattern by exploratory factor analysis. Results five dietary patterns were extracted by factor analysis: seasoning, animal and plant protein, traditional health, sweet food, drinking and beverage. The traditional health model is similar to the shrewd diet pattern, while the sweet food, drinking and beverage model is similar to the western dietary pattern. Multivariate logistic regression analysis showed that the traditional health model was positively correlated with male, old age, socio-economic status, healthy lifestyle, body mass index and waist circumference, while sweet and drinking patterns were associated with low age. Unhealthy lifestyle, body mass index, waist circumference were positively correlated (P0.05). Conclusion Dietary pattern is influenced by many factors, such as social demography and lifestyle. High SES, healthy lifestyle people tend to adopt a healthy diet model. Public education should be strengthened to promote a balanced diet, especially for people with low SES and unhealthy lifestyles.
