我们研究了免疫覆盖率（IMC）是否是婴儿死亡率（IMR）的预测因素之一，作为一个单一的指标，代表初级卫生保健（PHC）服务在发展中国家的可用性。多元回归分析显示，免疫接种率与IMR的偏相关系数为（-0.224），人均国民生产总值的对数（-0.294）、总和生育率（0.269），和成人识字率（-0.325）均具有统计学意义（p < 0.001）占世界所有发展中国家人口97%以上的97个发展中国家。97个国家的IMR与这四个变量的复相关系数为0.921。因此，发展中国家婴儿死亡率80%以上的变化可以由这四个变量的变化来解释。研究还表明，IMC具有良好的相关性，（简单相关）与初级保健服务提供情况的四个指标：获得当地护理（0.730），孕妇护理（0.603），分娩护理（0.666）和婴儿护理（0.553），在占所有发展中国家人口42%的48个发展中国家中，所有这些都具有统计意义（p < 0.001）。4个变量的复相关系数为0.787。约60%的内模传播变异可由这四个变量的变异来解释。因此，我们得出结论，免疫覆盖率是婴儿死亡率的主要预测因素之一。它是卫生干预措施的组成部分之一，可用作发展中国家初级保健服务提供情况的替代指标。亚太公共卫生杂志1994;7（4）：228-32.
We examined whether immunization coverage (IMC) is one of the predictors of infant mortality rate (IMR), as a single indicator representing the availability of primary health care (PHC) services in developing countries. Multiple regression analysis showed that partial correlation coefficients for IMR with immunization coverage (-0.224), logarithm of per capita GNP (-0.294), total fertility rate (0.269), and adult literacy rate (-0.325) were all statistically significant (p < 0.001) in 97 developing countries which make up more than 97% of the population in all developing countries of the world. Multiple correlation coefficients of IMR with these four variables in 97 countries was 0.921. Thus, more than 80% of variation of IMR in developing countries were explained by the variation of the four variables. The study also showed that IMC was well correlated (simple correlation) with the four indicators of the availability of primary health care services: access to local care (0.730), care of pregnant women (0.603), delivery care (0.666), and infant care (0.553), all of which were statistically significant (p < 0.001) in the 48 developing countries which make up 42% of the population of all developing countries. Multiple correlation coefficients of these four variables was 0.787. About 60% of the variation of IMC will be explained by the variation of the four variables. Thus we conclude that immunization coverage is one of the main predictors of the infant mortality rate. It represents one of the health intervention components which can be used as a proxy indicator of the availability of PHC service in developing countries. Asia Pac J Public Health1994;7(4): 228-32.
