目的:调查研究加拿大Ⅱ型糖尿病发病率与收入的相关性。方法:数据来源于加拿大统计局发布的加拿大社区健康调查(CCHS)报告,统计方法为logistic回归分析。结果:2005年加拿大罹患糖尿病约130万人,占总人口4.9%《,其中,低收入阶层患Ⅱ型糖尿病发病率是高收入阶层的4.14倍,且发病率随收入水平的增高而降低。低收入阶层的男性罹患糖尿病的相对风险度几乎为高收入阶层的2倍(OR 1.94,95%CI 1.57～2.39),而女性则接近3倍(OR 2.75,95%CI2.24～3.37)。结论:预防Ⅱ型糖尿病的发生,除应考虑肥胖、缺乏锻炼及不良饮食习惯等传统因素外,还需对引发糖尿病的社会因素给予关注。
Aims: To investigate the association between the incidence of type 2 diabetes in Canada and income. METHODS: The data were sourced from the Canadian Community Health Survey (CCHS) report published by Statistics Canada. The statistical method was logistic regression analysis. Results: In Canada, there were about 1.3 million diabetic patients in 2005, accounting for 4.9% of the total population. Among them, the incidence of type 2 diabetes in low-income groups was 4.14 times that of the high-income groups, and the incidence decreased as the income level increased. Men in low-income groups had almost twice the relative risk of developing diabetes (OR 1.94, 95% CI 1.57-2.39), while women nearly tripled their odds (OR 2.75, 95% CI 2.24-3.37). Conclusion: Prevention of type 2 diabetes should pay attention to the social factors causing diabetes mellitus, besides the traditional factors such as obesity, lack of exercise and poor eating habits.
