The relationship between age-specific mortality rates and some indices of health facilities and some environmental and dietary factors has been studied in 18 developed couuntries. The indices of health care are not negatively associated with mortality, and there is a marked positive association between the prevalence of doctors and mortality in the younger age groups. No explanation of this doctor anomaly has so far been found. Gross national product per head is the principal variable which shows a consistently strong negative association with mortality.
在18个发达国家中,研究了特定年龄死亡率与一些卫生设施指标以及一些环境和饮食因素之间的关系。医疗保健指标与死亡率并非负相关,而且在较年轻年龄组中,医生普及率与死亡率之间存在明显的正相关。迄今为止,尚未找到对这种医生异常现象的解释。人均国民生产总值是与死亡率始终呈现强烈负相关的主要变量。
