Among the 45,204 live births in Birmingham in the three calendar years 1981-3, there were 218 postneonatal deaths, giving a postneonatal mortality rate of 4.82 per 1000 live births. Postneonatal mortality rates were 4.22 for whites, 5.91 for Asians (relative risk 1.26, 95% confidence interval (CI) 1.04 to 1.53) and 8.20 for Afro-Caribbeans (relative risk 1.78, 95% CI 1.25 to 2.55). Among Asians malformations were common (3.36) and sudden infant death syndrome rare (1.18), in contrast to Afro-Caribbeans among whom the rates were 0.66 and 5.25, respectively. Logistic regression analysis demonstrated a significantly lower risk of sudden infant death syndrome (SIDS) in Asians and significantly raised risks of SIDS in very low birthweight babies and those with unemployed parent(s). Ethnic differences persisted after controlling for maternal age, social class, and birth weight. Studies of sociocultural differences in child rearing practices are needed and may uncover important aetiological factors of sudden infant death syndrome.
在1981年至1983年这三个日历年中，伯明翰有45,204例活产，其中有218例新生儿后期死亡，新生儿后期死亡率为每1000例活产4.82例。白人的新生儿后期死亡率为4.22，亚洲人为5.91（相对危险度1.26，95%置信区间（CI）为1.04至1.53），非洲加勒比人为8.20（相对危险度1.78，95%CI为1.25至2.55）。在亚洲人中，畸形很常见（3.36），婴儿猝死综合征很少见（1.18），相比之下，非洲加勒比人中的这两个比率分别为0.66和5.25。逻辑回归分析表明，亚洲人患婴儿猝死综合征（SIDS）的风险显著较低，极低出生体重儿和父母失业的婴儿患SIDS的风险显著升高。在控制了产妇年龄、社会阶层和出生体重后，种族差异依然存在。需要对育儿方式的社会文化差异进行研究，这可能会揭示婴儿猝死综合征的重要病因。
