In order to explore the validity of official infant mortality statistics, the number of infant deaths registered in the cohort of live births and resident in Navarra (Spain) from 1985 to 1989, according to data supplied by the Department of Statistics of Navarra, has been compared with that obtained in a retrospective search into the information of the hospitals. Among 24,383 live births of the cohort, 291 were certified as infant deaths. An over-register of 13 cases (4.5%) and an under-register of 26 cases (8.9%) was detected. By excluding those live births with less than six months of gestation, as done by the National Institute of Statistics, the validity is altered, because apart from the errors mentioned, one must add those resulting from the incorrect filling-in of the "number of weeks pregnant"= variable. When correcting these deficiencies, the final statistics (Infant Mortality Risk = 11.17 per 1000 live births) did not differ much from the official figures (IMR = 11.48 per 1000 live births).
为探究官方婴儿死亡率统计数据的有效性，根据西班牙纳瓦拉统计局提供的数据，对1985年至1989年在纳瓦拉出生并居住的活产队列中登记的婴儿死亡数量，与通过对医院信息进行回顾性检索获得的数据进行了比较。在该队列的24383例活产中，有291例被认证为婴儿死亡。发现有13例（4.5%）登记过多，26例（8.9%）登记过少。按照国家统计局的做法，排除那些妊娠期不足六个月的活产，有效性会发生改变，因为除了上述错误外，还必须加上因“怀孕周数”变量填写错误导致的误差。纠正这些缺陷后，最终统计数据（婴儿死亡风险为每1000例活产11.17例）与官方数据（婴儿死亡率为每1000例活产11.48例）相差不大。
