Perinatal mortality was estimated by the regression equation log10 Y = 0.7826log10X + 0.08, obtained by perinatal mortality (Y) and maternal mortality (X) in Japan in 1960-1990. The error rate was approximately 9% in the estimation. Unpublished Japanese perinatal mortality in 1899-1947 was estimated from maternal mortality by using the equation, and appropriate results were obtained. Perinatal mortalities of the world's countries were estimated from their maternal mortalities listed in UNICEF reports with use of the above equation. Two peaks were noted in the country number distribution at 0-19 and 120-140 of estimated perinatal mortality. The mortality was 20-99 in 43% of 111 countries analyzed and 100 or more in 25%. The results suggest that further efforts should be made for the improvement of worldwide maternal and child health.
围产期死亡率是通过回归方程log10 Y = 0.7826log10X + 0.08估算得出的，该方程是根据1960 - 1990年日本的围产期死亡率（Y）和孕产妇死亡率（X）得到的。估算中的错误率约为9%。利用该方程从孕产妇死亡率估算出了1899 - 1947年日本未公布的围产期死亡率，并得到了合适的结果。利用上述方程，根据联合国儿童基金会报告中列出的世界各国孕产妇死亡率估算了这些国家的围产期死亡率。在估算的围产期死亡率为0 - 19和120 - 140时，国家数量分布出现了两个峰值。在分析的111个国家中，43%的国家死亡率为20 - 99，25%的国家死亡率为100或更高。结果表明，应进一步努力改善全球母婴健康状况。
