The aim of this follow-up study, based on individual data, was to analyse the influence of ethnicity and other demographic and social factors on suicide rates between 1986 and 1989 for the Swedish population according to the 1985 census. The data were analysed by sex and age using a Poisson regression model. During the study period there were 8,310 cases of suicide and undetermined death. The main finding in this study was that ethnicity, defined as being foreign-born, was a significant risk factor for suicide in both sexes and in all age groups except for males aged 30 to 49 years. Not being married was a significant risk factor in all age groups for both males and females. Form of tenure, i.e. living in rented flats, was a significant risk factor for suicide in middle-aged males and females, while over-crowding was a risk factor for middle-aged males and for the over 50's of both sexes. As ethnicity, defined as foreign-born, was an important variable related to suicide, the association between different ethnic groups and suicide will be evaluated in forthcoming studies.
这项基于个体数据的随访研究旨在根据1985年人口普查分析种族以及其他人口和社会因素对1986年至1989年瑞典人口自杀率的影响。使用泊松回归模型按性别和年龄对数据进行分析。研究期间有8310例自杀和死因不明的死亡案例。该研究的主要发现是，以外籍出生定义的种族是除30至49岁男性外所有年龄段和性别的自杀显著风险因素。未婚是所有年龄段男性和女性的显著风险因素。居住形式，即住在出租公寓，是中年男性和女性自杀的显著风险因素，而过度拥挤是中年男性以及50岁以上男女的风险因素。由于以外籍出生定义的种族是与自杀相关的一个重要变量，不同种族群体与自杀之间的关联将在后续研究中进行评估。
