不少学者在计算新生儿病死亡率时用了下列公式: 新生儿病死亡率=某年新生儿病死亡人数/同年平均人口数××100,000/10万(1)如《中国公共卫生》1990年第2期93页,《中华流行病学杂志》1988年特刊1号224页,《中国疾病监测》1990年第3期47页,《中国卫生统计》1990年第1期36页,等等。显然,式(1)来源于某病死亡专率计算公式。卫生部有关卫生统计汇编资料,如《中国卫生年鉴》、《中国卫生统计提要》等,计算新生儿病死亡率时则用:新生儿病死亡率=某年新生儿病死亡人数/同年活产婴儿数×100,000/10万(2)
Many scholars use the following formula to calculate the neonatal mortality rate: Neonatal mortality rate = annual neonatal deaths / the same year the average number of people × × 100,000 / 100,000 (1) as the “Chinese Public Health” 1990 Issue 2, Issue 93, Chinese Journal of Epidemiology 1988, Issue 1, No. 224, Chinese Disease Surveillance, 1990, No.3, 47, Health Statistics of China, No. 1, 1990, pp. 36 . Obviously, equation (1) is derived from the formula of mortality rate of a certain disease. Ministry of Health compilation of health statistics on information, such as “China Health Almanac”, “China’s health statistics,” and so on, the calculation of neonatal mortality rate is used: neonatal mortality = annual neonatal deaths / live in the same year Infants × 100,000 / 100,000 (2)
