The objective was to analyse differences in the epidemiological pattern of sudden death in infancy during two time periods--the Sudden Infant Death Syndrome (SIDS) 'epidemic': 1984-1989, and the period of rapid decline in the SIDS rate 1990-1996. Sex distribution, age, sleeping position, signs of infection, day of the week and place of death were registered and compared for the two time periods studied in all SIDS cases autopsied at the Institute of Forensic Medicine, Oslo. There were significantly more deaths in the age group under four months in the period 1984-89 than in the second period. Prone sleeping position, signs of infection, death outdoors and during the winter were more frequent during the first period than in the second. These features also were more frequent in the age group under four months than in the older babies during the first period. The shift in the epidemiological pattern after 1990, when the risk factor campaign was launched, indicates that prone sleeping position, cold climate, sleeping outdoors and infections seem to be risk factors that are particularly harmful to the youngest infants.
目的是分析两个时间段内婴儿猝死流行病学模式的差异——婴儿猝死综合征（SIDS）“流行期”：1984年至1989年，以及SIDS发生率迅速下降的时期1990年至1996年。对在奥斯陆法医学研究所进行尸检的所有SIDS病例，登记并比较了两个研究时间段内的性别分布、年龄、睡眠姿势、感染迹象、死亡星期几和死亡地点。1984 - 89年期间四个月以下年龄组的死亡人数明显多于第二个时期。第一个时期俯卧睡眠姿势、感染迹象、户外死亡和冬季死亡比第二个时期更频繁。在第一个时期，这些特征在四个月以下年龄组也比大龄婴儿更频繁。1990年开展危险因素宣传活动后流行病学模式的转变表明，俯卧睡眠姿势、寒冷气候、户外睡眠和感染似乎是对最年幼婴儿特别有害的危险因素。
