In an investigation of a possible relationship between falling perinatal mortality and rising rates of adolescent suicide, 46 risk factors from the prenatal, birth, and neonatal records of 52 adolescents who committed suicide before age 20 and 2 matched controls for each subject were analysed blind. The results showed statistically significant differences between the suicide victims and each of the controls and no difference between the controls. Three specific risk factors were shown to have a powerful capacity to differentiate the suicides from the controls: (i) respiratory distress for more than 1 h at birth; (ii) no antenatal care before 20 weeks of pregnancy; and (iii) chronic disease of the mother during pregnancy.
在一项关于围产期死亡率上升与青少年自杀率上升之间可能存在的关系的调查中，对52名20岁前自杀的青少年的产前、出生和新生儿记录中的46个风险因素进行了盲法分析，并为每个受试者匹配了2名对照。结果显示，自杀受害者与每个对照组之间存在统计学上的显著差异，而对照组之间没有差异。有三个特定的风险因素显示出能够有力地区分自杀者与对照组：（i）出生时呼吸窘迫超过1小时；（ii）怀孕20周前未接受产前护理；（iii）母亲在怀孕期间患有慢性病。
