Premature death from suicide is a leading cause of death worldwide. However, the pattern and risk factors for suicide and other external cause injuries are not well understood. This study investigates mortality from suicide and other injuries and associated risk factors in China.
A prospective cohort study of 169,871 Chinese adults aged 40 years and older was conducted. Mortality due to suicide or other external cause injuries was recorded.
Mortality from all external causes was 58.7/100,000 (72.3 in men and 44.4 in women): 14.1/100,000 (14.2 in men and 14.2 in women) for suicide and 44.6/100,000 (58.1 in men and 30.2 in women) for other external cause injuries. Transport accidents (17.2/100,000 overall, 23.4 in men and 10.8 in women), accidental poisoning (7.5/100,000 overall, 10.2 in men and 4.8 in women), and accidental falls (5.7/100,000 overall, 6.5 in men and 5.0 in women) were the three leading causes of death from other external cause injuries in China. In the multivariable analysis, male sex (relative risk [RR] 1.56, 95% confidence interval [CI] 1.03-2.38), age 70 years and older (2.27, 1.29-3.98), living in north China (1.68, 1.20-2.36) and rural residence (2.82, 1.76-4.51) were associated with increased mortality from suicide. Male sex (RR 2.50, 95% CI 1.95-3.20), age 60-69 years (1.93, 1.45-2.58) and 70 years and older (3.58, 2.58-4.97), rural residence (2.29, 1.77-2.96), and having no education (1.56, 1.00-2.43) were associated with increased mortality from other external cause injuries, while overweight (0.60, 0.43-0.83) was associated with decreased risk of mortality from other external cause injuries.
External cause mortality has become a major public health problem in China. Developing an integrated national program for the prevention of mortality due to external cause injuries in China is warranted.
自杀导致的过早死亡是全球范围内的主要死亡原因之一。然而，自杀和其他外部原因伤害的模式和风险因素尚不清楚。本研究调查了中国自杀和其他伤害导致的死亡率和相关风险因素。
对 169871 名年龄在 40 岁及以上的中国成年人进行了前瞻性队列研究。记录自杀和其他外部原因伤害导致的死亡率。
所有外部原因导致的死亡率为 58.7/100000（男性为 72.3/100000，女性为 44.4/100000）：14.1/100000（男性为 14.2/100000，女性为 14.2/100000）为自杀，44.6/100000（男性为 58.1/100000，女性为 30.2/100000）为其他外部原因伤害。在中国，交通意外（总体 17.2/100000，男性 23.4/100000，女性 10.8/100000）、意外中毒（总体 7.5/100000，男性 10.2/100000，女性 4.8/100000）和意外跌倒（总体 5.7/100000，男性 6.5/100000，女性 5.0/100000）是导致其他外部原因伤害导致死亡的三大原因。在多变量分析中，男性（相对风险 [RR] 1.56，95%置信区间 [CI] 1.03-2.38）、70 岁及以上（2.27，1.29-3.98）、居住在华北地区（1.68，1.20-2.36）和农村地区（2.82，1.76-4.51）与自杀导致的死亡率增加相关。男性（RR 2.50，95%CI 1.95-3.20）、60-69 岁（1.93，1.45-2.58）和 70 岁及以上（3.58，2.58-4.97）、农村地区（2.29，1.77-2.96）和未受过教育（1.56，1.00-2.43）与其他外部原因伤害导致的死亡率增加相关，而超重（0.60，0.43-0.83）与其他外部原因伤害导致的死亡率降低相关。
外部原因导致的死亡率已成为中国的一个主要公共卫生问题。中国有必要制定一个综合的全国性预防外部原因伤害导致死亡率的方案。
