The objective of this study was to obtain an accurate register of the deaths of children less than one year of age in order to discover the real infant mortality (IM) rate in Navara and its trend during the period between 1985 and 1996, a well as to investigate the deaths by sudden infant death (SID) in the same period and their relationship to the prone position during sleep.
Infant mortality was determined by detailed examination of all certified deaths. Research into possible nonregistered deaths was also carried-out. The sources of information included the archives and registers of the pediatric and obstetric wards and pathology departments of all hospitals. Deaths codified as 798.0 (CIE9 infinity R) were included in the study as death by SID. To determine sleeping posture. In the second semester of 1996, a survey was carried out on a sample of 285 children of under 6 months of age. The survey's model is the same as that published previously.
In the period of 1985 to 1992, IM was 12.33 per thousand live births. The SID rate was 1.30/1,000 live births. The prevalence of the prone position is unknown. In the period between 1993 and 1996, IM decreased to 5.84/1,000 live births and this decrease was proportional in both the neonatal and postneonatal components. The rate of SIM decreased to 0.44/1,000 live births. At the beginning of 1993, 86% of the children slept in the prone position, in 1994, 38% and in 1996, only 23%.
Trustworthy data in Navarra shows a decrease in IM of more than 50% from 1993 on. The SID rate also decreased by 65%, coinciding with a massive drop in the use of the prone position during sleep.
本研究的目的是获得一份准确的一岁以下儿童死亡登记册，以发现纳瓦拉地区的实际婴儿死亡率（IM）及其在1985年至1996年期间的趋势，同时调查同期婴儿猝死（SID）死亡情况及其与睡眠时俯卧位的关系。
通过详细检查所有已认证的死亡病例来确定婴儿死亡率。还对可能未登记的死亡病例进行了调查。信息来源包括所有医院的儿科和产科病房以及病理科的档案和登记册。编码为798.0（CIE9无穷大R）的死亡病例作为SID死亡纳入研究。为确定睡眠姿势，1996年下半年对285名6个月以下儿童的样本进行了调查。该调查模型与之前发表的相同。
在1985年至1992年期间，IM为每千例活产12.33例。SID率为每千例活产1.30例。俯卧位的患病率未知。在1993年至1996年期间，IM降至每千例活产5.84例，并且这种下降在新生儿和新生儿后期部分都是成比例的。SIM率降至每千例活产0.44例。1993年初，86%的儿童睡眠时采用俯卧位，1994年为38%，1996年仅为23%。
纳瓦拉地区的可靠数据显示，自1993年起IM下降超过50%。SID率也下降了65%，这与睡眠时俯卧位使用的大幅下降相吻合。
