To examine the association of income inequality at the public health unit level with individual health status in Ontario.
Cross-sectional multilevel study carried out among subjects aged 25 years or older residing in 42 public health units in Ontario. Individual-level data drawn from 30,939 respondents in 1996-97 Ontario Health Survey. Median area income and income inequality (Gini coefficient) calculated from 1996 census. Self-rated health status (SRH) and Health Utilities Index (HUI-3) scores were used as main outcomes.
Controlling for individual-level factors including income, respondents living in public health units in the highest tercile of income inequality had odds ratios of 1.20 (95% CI 1.04 - 1.38) for fair/poor self-rated health, and 1.11 (95% CI 1.01 - 1.22) for HUI score below the median, compared with people living in public health units in the lowest tercile. Controlling further for median area income had little effect on the association.
Income inequality was significantly associated with individual self-reported health status at public health unit level in Ontario, independent of individual income.
研究安大略省公共卫生单位层面的收入不平等与个体健康状况之间的关联。
对居住在安大略省42个公共卫生单位中年龄在25岁及以上的受试者进行横断面多层次研究。个体层面的数据来自1996 - 1997年安大略省健康调查中的30939名受访者。根据1996年人口普查计算地区收入中位数和收入不平等(基尼系数)。自我评估健康状况(SRH)和健康效用指数(HUI - 3)得分用作主要结果。
在控制包括收入在内的个体层面因素后,与生活在收入不平等程度最低三分位公共卫生单位的人群相比,生活在收入不平等程度最高三分位公共卫生单位的受访者自我评估健康状况为一般/较差的比值比为1.20(95%置信区间1.04 - 1.38),健康效用指数得分低于中位数的比值比为1.11(95%置信区间1.01 - 1.22)。进一步控制地区收入中位数对这种关联影响不大。
在安大略省,公共卫生单位层面的收入不平等与个体自我报告的健康状况显著相关,且独立于个体收入。
