文化程度和甘油三酯交互作用对中老年人肥胖的影响分析

Analysis of the influence of interaction between educational level and triglyceride on obesity among middle-aged and elderly people

目的了解蚌埠地区中老年人群不同肥胖程度的现状,探讨文化程度和甘油三酯对肥胖的影响,为进一步分析中老年不同肥胖程度相关因素及合理提出改善措施提供依据。方法于2015年7—8月对安徽省蚌埠市龙子湖区的居民进行随机抽查,将年龄≥45岁的中老年居民作为研究对象,共2081人,采用统一问卷调查、实验室检测和体格指标检测,来评估文化程度和甘油三酯对中老年人不同肥胖程度的影响。结果将年龄、性别、收入、吸烟和饮酒作为混杂因素纳入logistic回归模型,发现文化程度、甘油三酯与中老年人一般性肥胖和中心型肥胖均存在统计学关联(P<0.05)。进一步分析,文化程度和甘油三酯交互作用对中老年人不同肥胖程度的影响,结果显示,文化程度低且甘油三酯异常与中老年一般性肥胖和中心型肥胖均成正相关(P<0.05);而文化程度高且甘油三酯正常与中老年一般性肥胖和中心型肥胖均成负相关(P<0.05);文化程度高且甘油三酯异常与中老年中心型肥胖成正相关(P<0.05),而对中老年一般性肥胖不存在关联作用。结论文化程度低对中老年一般性和中心型肥胖均存在风险;而文化程度高且甘油三酯正常时对中老年肥胖有保护作用。

Objective To investigate the status of different obesity levels among middle-aged and old people in Bengbu,and to explore the influence of education level and triglyceride on obesity,and then analyze the factors related to obesity in middle-aged and elderly and reasonable improvement measures.Methods A random sample of residents of Longzihu district of Bengbu City,Anhui Province was enrolled.The middle-aged and elderly residents aged 45 years or older were the subjects of the study and there were 2081 people.Uniform questionnaire surveys,laboratory tests,and physical indicators were used to assess the impact of education and triglycerides on the degree of obesity in middle-aged and elderly people.Results The indicators including age,sex,income,smoking,and drinking were enrolled as a confounding factor in the logistic regression model,the results revealed that education level and triglyceride levels in middle-aged and elderly people was statistically associated with general obesity and central obesity(P<0.05).Further discussion of the impact of education and triglyceride interactions on different obesity levels in the elderly and middle-aged people,showed that low levels of education and abnormal triglycerides were positively associated with general obesity and central obesity in middle-aged and older adults(P<0.05);while high education levels and normal triglycerides were negatively associated with general obesity and central obesity in middle-aged and older adults(P<0.05).High education levels and abnormal triglyceride levels were positively correlated with middle-aged and elderly central obesity(P<0.05),but there was no correlated effect on general obesity middle-aged and elderly.Conclusions Low educational level is a risk factor for central obesity in the middle-aged and elderly population,while high educational level and normal triglycerides concentration is a protective factor for obesity in the middle-aged and elderly population.
