Various studies have enquired into the influence of socioeconomic development or public health measures on life expectancies in less developed countries. Analysis of the effect of these two groups of factors upon life expectancy, using data for 95 less developed countries, indicates that mortality is primarily influenced by such socioeconomic development measures as urbanization, industrialization, and education, and secondarily by such public health measures as access to safe water, physicians, and adequate nutrition.
多项研究探讨了社会经济发展或公共卫生措施对欠发达国家预期寿命的影响。利用95个欠发达国家的数据，分析这两组因素对预期寿命的影响表明，死亡率主要受城市化、工业化和教育等社会经济发展措施的影响，其次受获得安全饮用水、医生和充足营养等公共卫生措施的影响。
