The present study analysed changes in sex-specific suicide rates in Canada from 1971 to 1985. A significant increase in the male-to-female ratio of suicide rates was observed. Our analysis of sex-specific age-adjusted rates revealed that this increasing ratio was a function of both increasing male rates and decreasing female rates, but that the latter was more marked. This divergence of male and female rates within the last decade and a half parallels similar changes noted both in the US and in the majority of European countries, but contrasts with a pattern of converging rates throughout North America and much of Europe prior to 1970.
本研究分析了1971年至1985年加拿大特定性别自杀率的变化。观察到自杀率的男女比例显著增加。我们对特定性别年龄调整率的分析表明，这种上升的比例是男性自杀率上升和女性自杀率下降共同作用的结果，但后者更为明显。在过去十五年中，男性和女性自杀率的这种差异与美国和大多数欧洲国家所观察到的类似变化相似，但与1970年以前北美和欧洲大部分地区自杀率趋同的模式形成对比。
