Risk factors for sudden infant death syndrome (SIDS) were examined in a prospective study based on Swedish births between 1983 and 1985. All infants surviving the first week of life were included (279,938). The overall rate of SIDS was 0.7 per 1,000 first week survivors. Elevated relative risks were associated with low maternal age, multiparity, maternal smoking, and male infants. Smoking doubled the risk and a clear dose-response relation by amount smoked was observed. Maternal smoking also seemed to influence the time of death, as infants of smokers died at an earlier age. In countries like Sweden, smoking may be the single most important preventable risk factor for sudden infant death syndrome.
基于1983年至1985年瑞典出生人口进行了一项前瞻性研究，对婴儿猝死综合征（SIDS）的风险因素进行了调查。纳入了所有度过生命第一周的婴儿（共279,938名）。SIDS的总体发生率为每1000名度过第一周的幸存者中有0.7例。较高的相对风险与母亲年龄低、多胎妊娠、母亲吸烟以及男婴有关。吸烟使风险加倍，并且观察到吸烟量与风险之间存在明确的剂量反应关系。母亲吸烟似乎也影响死亡时间，因为母亲吸烟者的婴儿死亡年龄更早。在瑞典这样的国家，吸烟可能是婴儿猝死综合征唯一最重要的可预防风险因素。
