采用婴儿死亡率指数(IMI)及可预防性死亡指数(PDI)来评价、分析179例城乡0～4岁儿童的死亡原因与死亡率水平。在文化、经济发达的城市IMI明显低于农村地区,PDI呈负值(-10.27),儿童的主要死因为内源性疾病。农村地区PDI为13.4,儿童的死因以外源性疾病为主。为降低儿童死亡率制定政策和措施提供科学依据。 The infant mortality index (IMI) and preventable death index (PDI) were used to evaluate the causes and mortality of 179 children from 0 to 4 years in urban and rural areas. The IMI in the culturally and economically developed cities was significantly lower than that in rural areas, with a negative PDI (-10.27) and the leading cause of death among children was endogenous disease. PDI in rural areas was 13.4, the cause of death of children with exogenous diseases. Provide a scientific basis for setting policies and measures to reduce child mortality.
