To test whether the cardiovascular disease declines in North Karelia were accompanied by subjective improvements in health, we analyzed responses to two questions about perceived risk of heart disease and health status on independent random population samples surveyed 10 years apart. Age stratified perceived risk of heart disease declined significantly more (p less than .01) and age stratified perceived health status improved significantly more in North Karelia than in the reference area (p less than .005).
为了检验北卡累利阿地区心血管疾病的下降是否伴随着健康状况的主观改善,我们分析了针对两个问题的回答,这两个问题涉及相隔10年独立随机抽样调查的人群对心脏病感知风险和健康状况的看法。在北卡累利阿地区,按年龄分层的心脏病感知风险下降幅度显著更大(p小于0.01),且按年龄分层的感知健康状况改善幅度也显著大于参照地区(p小于0.005)。
