To study in detail the differences in infant mortality between Denmark and Sweden.
Data retrieved from national health registers on infant death rates were compared for 1980-1988, supplemented with a study on the impact of socio-economic conditions in 1985-86 (Denmark) or 1986 (Sweden).
Even after stratification for maternal age, parity, and socio-economic group, the Danish mortality rate was higher in all age-at-death intervals except for stillbirths. Maternal age-parity distribution was more favourable in Denmark, the socio-economic distribution in Sweden. The most marked country differences was seen in young women. The difference in the rate of perinatal deaths but not of later deaths is explainable by a more favourable birth weight distribution in Sweden than in Denmark.
The studied variables do not explain the difference in mortality risk but it may be due to life style factors so far not identified.
详细研究丹麦和瑞典婴儿死亡率的差异。
比较了从国家健康登记处获取的1980 - 1988年婴儿死亡率数据，并补充了一项关于1985 - 1986年（丹麦）或1986年（瑞典）社会经济状况影响的研究。
即使按母亲年龄、胎次和社会经济群体进行分层后，丹麦除死产外所有死亡年龄区间的死亡率均较高。丹麦的母亲年龄 - 胎次分布更有利，瑞典的社会经济分布更有利。在年轻女性中观察到最显著的国家差异。瑞典围产期死亡率的差异而非后期死亡率的差异可以用瑞典比丹麦更有利的出生体重分布来解释。
所研究的变量无法解释死亡风险的差异，这可能归因于迄今尚未确定的生活方式因素。
