背景：教育水平和家庭收入(作为社会经济地位的替代指标)与心血管疾病风险因素之间的负相关关系已经得到了很好的证实。方法：对25~74岁明尼阿波利斯-圣保罗居民的人群样本(1980-1982年3334人，1985-1987年4538人，1990-1992年4517人)的心血管疾病危险因素趋势进行混合回归模型分析。结果：男女文化程度与血清胆固醇水平、血压、吸烟率、体重指数呈负相关，与闲暇体育活动和健康知识呈正相关。家庭收入与女性的收缩压和体重指数呈负相关，而在两性中与吸烟流行率呈负相关。男女收入水平与闲暇时间、体育活动和健康知识呈正相关。在所有社会经济地位群体中，血清胆固醇水平和收缩压总体呈长期有利的下降趋势，健康知识呈有利的上升趋势，而体重指数呈不利的上升趋势。在整个十年中，男性吸烟率的趋势因受教育程度的不同而不同(P=0.01)，因此只有那些拥有大学学位或受过大学教育的人才能观察到下降。就闲暇时间体力活动的趋势而言，社会经济地位较低的男性(受教育程度为P=0.03；收入为P=0.02)和较不富裕的女性(P=.001)有更大的增长。结论：这些数据支持社会经济地位与心血管疾病风险因素之间的负相关，但表明在过去十年中，在具有代表性的明尼阿波利斯-圣保罗人口样本中，风险因素趋势的社会经济差异并未扩大(男性受教育程度的吸烟除外)。
Background: Inverse associations of educational level and household income (as proxy indicators of socioeconomic status)with cardiovascular disease risk factors are fairly well established. Whether differences in cardiovascular disease risk factors across education or income levels have widened in the last decade remains an issue of considerable public health importance.Methods: Analysis by mixed-regression models of trends in cardiovascular disease risk factors, in population-based samples (n=3334 in 1980-1982, n=4538 in 1985-1987, and n=4517 in 1990-1992) of Minneapolis-St Paul residents 25 to 74 years old.Results: Education level was inversely related to serum cholesterol level, systolic blood pressure, smoking prevalence, and body mass index and positively related to leisure-time physical activity and health knowledge in both sexes. Household income was inversely associated with systolic blood pressure and body mass index in women and with smoking prevalence in both sexes. Income level was positively associated with leisure-time physical activity and health knowledge in both sexes. There were overall favorable downward secular trends in serum cholesterol level and systolic blood pressure, favorable upward trends in health knowledge, and unfavorable upward trends in body mass index across all socioeconomic status groups. Throughout the decade, trends in smoking prevalence differed by education level in men (P=.01), such that declines were observed only in those with a college degree or some college education. With respect to trends in leisure-time physical activity, there were greater gains among men with low socioeconomic status (P=.03 for education; P=.02 for income) and among less affluent women (P=.001).Conclusions: These data support the inverse association between socioeconomic status and cardiovascular disease risk factors but suggest no widening (with the exception of smoking by education level in men) of socioeconomic differences in risk factor trends during the last decade in a representative sample of the Minneapolis-St Paul population.
