BackgroundPremature 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.

MethodsA 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.

ResultsMortality 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.

ConclusionsExternal 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.
