目的了解南京市城区居民的膳食模式与腰围(WC)及血脂的关系。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,分析不同膳食模式与腰围及血脂的关系。结果因子分析共得到5种膳食模式:调味品模式、动植物蛋白质模式、传统健康模式、甜食模式和饮品模式。经多因素调整后,越倾向动植物蛋白质模式的人群WC、总胆固醇(TC)、甘油三酯(TG)水平越高;越倾向于传统健康模式的人群WC水平越低;越倾向于饮品模式的人群WC和TG水平越高。饮品模式人群的WC水平高于其他4种膳食模式人群;饮品模式和动植物蛋白质模式人群的TG高于其他3种膳食模式人群。结论膳食模式与WC、TC及TG密切相关。
Objective To understand the relationship between dietary patterns and waist circumference (WC) and blood lipids in urban residents in Nanjing. Methods The multi-stage stratified cluster random sampling method was used to investigate the permanent residents aged 30 years and over in 7 communities in two urban districts of Nanjing. A specially designed food frequency scale was used to establish a dietary pattern using exploratory factor analysis to analyze the relationship between different dietary patterns and waist circumference and blood lipids. Results Five kinds of dietary patterns were obtained by factor analysis: condiment pattern, animal and plant protein pattern, traditional health pattern, sweet pattern and drink pattern. After adjusting for multiple factors, the WC, TC and TG levels in the animal and plant protein models tended to be higher; the WC patients in the more traditional health mode were lower; the more inclined to the drink mode The higher the level of WC and TG in the crowd. The level of WC was higher in drink-mode than in other four diet-mode populations; TG in drink mode and animal-plant protein mode was higher than in other three diet-mode populations. Conclusion Dietary patterns are closely related to WC, TC and TG.
