To study the space-time distribution of suicide in Galicia from 1976 to 1998, taking into account gender, age, season and method of suicide.
For each sex crude and age-adjusted rates per province and age-specific rates per period (1978-84, 1985-91, 1992-98) were calculated. To estimate mortality risk and time trends in the municipalities, a Bayesian hierarchical model was used.
In the last few years mortality from suicide has increase considerably. Age-adjusted rates of 6 per 105 at the beginning of the study rose to 10 per 105 at the end. The increase was greatest among men. The higher rates were observed in the elderly, although in terms of time trends the highest increase occurred among adolescents and young adults. In both sexes the main method of suicide was hanging. Less common methods were jumping from a height and shooting. The greatest number of suicides took place during the spring and summer months. In terms of spatial distribution, a high number of suicides were committed in the province of Lugo; in the municipalities, mortality risk decreased from North to South and an inverse temporal trend was observed in both sexes. This differed from the space-time patterns of suicides committed using methods other than hanging.
Suicide is an important health problem in Galicia not only because to its magnitude but also because of the increasing rates, especially among young people. Geographical and temporal analysis can identify priority areas where preventive policies should be implemented.
研究1976年至1998年加利西亚地区自杀的时空分布情况，同时考虑性别、年龄、季节和自杀方式。
计算每个省份按性别划分的粗死亡率和年龄调整死亡率，以及每个时期（1978 - 84年、1985 - 91年、1992 - 98年）的年龄别死亡率。为了估计各市镇的死亡风险和时间趋势，使用了贝叶斯分层模型。
在过去几年中，自杀死亡率大幅上升。研究开始时年龄调整后的自杀率为每10万人中有6人，到研究结束时升至每10万人中有10人。男性的上升幅度最大。老年人的自杀率较高，不过从时间趋势来看，青少年和年轻人的自杀率上升幅度最大。在男女两性中，自杀的主要方式都是上吊。不太常见的方式是跳楼和枪击。自杀事件最多发生在春季和夏季。在空间分布方面，卢戈省的自杀人数较多；在各市镇中，死亡风险从北向南降低，且在男女两性中均观察到相反的时间趋势。这与非上吊方式自杀的时空模式不同。
自杀在加利西亚是一个重要的健康问题，不仅因为其规模，还因为自杀率不断上升，尤其是在年轻人中。地理和时间分析可以确定应实施预防政策的重点地区。
