Suicide rate in Japan surged in 1998. Although the standardized mortality ratios (SMRs) of suicide in Osaka Prefecture, Japan had been mostly lower than the national SMRs of suicide between 1980 and 1997, they surpassed the increased national SMR of suicide in 1998 and 1999. We investigated whether the suicide rates for 1980-97 and the recent increased suicide rates in Osaka Prefecture were associated with socioeconomic factors. Time-series regression analyses of the suicide rate and socioeconomic factors were performed on respective data for five sub-areas in Osaka Prefecture. The suicide rates of young people and middle-aged men were more strongly associated with the job application and divorce rates for 1980-99 than for 1980-97. Some relations between the suicide rate and public assistance rate were found. The suicide rate was negatively associated with the marriage rate in some areas. The suicide rate of elderly women was strongly associated with the number of persons per household. The notable relation was found between the suicide rate of middle-aged men and the job application rate for 1980-99. The inverse relation between the suicide rate of elderly women and the number of persons per household was noteworthy.
1998年日本的自杀率激增。尽管1980年至1997年间日本大阪府自杀的标准化死亡率（SMRs）大多低于全国自杀SMRs，但在1998年和1999年却超过了上升后的全国自杀SMR。我们调查了1980 - 1997年大阪府的自杀率以及近期上升的自杀率是否与社会经济因素相关。对大阪府五个分区各自的数据进行了自杀率和社会经济因素的时间序列回归分析。1980 - 1999年期间，年轻人和中年男性自杀率与求职率和离婚率的关联比1980 - 1997年期间更强。发现了自杀率与公共援助率之间的一些关系。在某些地区，自杀率与结婚率呈负相关。老年女性的自杀率与每户人数密切相关。1980 - 1999年期间中年男性的自杀率与求职率之间存在显著关系。老年女性自杀率与每户人数之间的反比关系值得注意。
