“…The finding of a history of mental illness as an independent risk factor for suicide in our study is consistent with some studies in China [6,32,34] and Western countries [7,[54][55][56] . In Western cultures, psychological autopsy studies revealed that 90-95 percent of suicide victims had a diagnosable psychiatric disorder at the time of the suicide [1] , but only about half of suicide victims in China had a history of psychiatric diagnosis at the time of death [4,6,32,34] .…”

“…Similarly, in other developing countries, patients with psychiatric disorders and suicide thoughts were commonly undiagnosed and untreated [7,61] . Recent studies from the WHO [9,10] and China [5,32,62] have shown that psychiatric disorders played an important role in suicidal behaviors. Clearly, diagnosis and treatment of psychiatric disorders should be a part of any suicide prevention plan.…”

“…In China, about a half of suicide victims did not have a psychiatric diagnosis at the time of death [4,[32][33][34] . Impulsive suicide and suicide attempts have been reported in rural Chinese residents [34,37,[72][73] and other countries [74] .…”

“…However, in India, Pakistan, and Iran, majority of suicide victims were married and being married was even a risk factor for suicide, especially in women [21][22][23] . History of mental illness has also been reported as a robust risk factor for suicide in developed counties [1,25] , but in China, more than 47% suicide victims did not have a psychiatric diagnosis at the time of death [4,[32][33][34] . In addition to these national-level differences, people living in the same country also had different risks for suicide because of their differences in religion, ethnicity, or geographic locations [1,25] .…”

Objective: Suicide is a major public health problem in China, particularly in rural areas. This study aimed to examine the rate and the risk factors for suicide in a rural area of China. Methods: The mortality data of two counties in Shandong Province from January 1st, 2004 to December 31st 2005 were used. Death information was collected via face-to-face interview with informant(s). Psychological autopsy was conducted on 137 completed suicides and 137 matched controls died from other illnesses. Chisquare/Fisher exact and multiple logistic regression were used for bivariate analyses and predictor analyses, respectively. Results: The suicide rate was 20.90 per 100,000 persons per year with almost equal rates of males and females. Among those with the age over 40 years old, the suicide rate in males was significantly higher than that in females. The peak of suicide fell in the age group of 70-79 years for males and the age group of ≥ 80 years for females. The most commonly used method for suicide was pesticide ingestion (76.7%). Poor interpersonal relationship (OR=12.79), childhood adversities (OR=7.26), a history of mental illness (OR=5.95), adverse life event(s) within 1 year prior to death (OR=3.19), and unstable extravert personality traits (OR=6.12) were independent risk factors for suicide. Male gender positively interacted with majority of these risk factors, especially with a history of mental illness (OR=17.89). Advanced age positively interacted with all independent risk factors, with a history of mental illness having the largest OR of 1.51 as every 10 year of age advancement. In bivariate analyses, a history of previous suicide attempt (OR=13.06), a family history of suicide (OR=7.08), and unstable introvert personality trait (OR=1.83) were also associated with increased risk for suicide; and stable extravert personality trait (OR=0.21) was associated with decreased risk for suicide. Conclusions: In this rural population of mainland China, the risk for suicide was almost equal in both males and females with the elderly having the highest risk. The positive interactions of advanced age and male gender with independent risk factors suggest that suicide prevention strategies targeting specific groups with different risk factors are essential.
