During the period 1973--1976, a significant decrease in perinatal mortality from 14.2 to 10.4/10 newborns occurred in Sweden. In the Stockholm area, the mean perinatal mortality during the same period varied significantly between the different maternity hospitals, even when pre-term and high risk pregnancies were excluded from the comparison. The majority of hospitals with fewer deliveries and without pediatric wards had a perinatal mortality above the mean. Some explanations of these differences were also looked for in differences between the total population of the referral area of each maternity hospital. In the referral areas of the hospitals with a perinatal mortality above the mean, there were higher percentages of low-income households and over-crowded dwellings and fewer professional people than in the other area. The results suggest a need for analysis of individually-based data to find etiological factors which account for differences in perinatal mortality.
在1973年至1976年期间，瑞典围产期死亡率从每10名新生儿14.2例显著降至10.4例。在斯德哥尔摩地区，即使在比较中排除了早产和高危妊娠情况，同一时期不同产科医院的平均围产期死亡率仍有显著差异。大多数分娩量较少且没有儿科病房的医院围产期死亡率高于平均水平。人们还从各产科医院转诊区域总人口的差异中寻找这些差异的一些解释。在围产期死亡率高于平均水平的医院转诊区域，低收入家庭和居住拥挤的家庭所占百分比更高，专业人员比其他区域更少。结果表明需要分析基于个体的数据，以找出导致围产期死亡率差异的病因因素。
