BackgroundSuicide is an urgent public health challenge for China. This study aims to examine the prevalence, influence factors, and gender differences of suicidal ideation among general population in Northwestern Urban China.

MethodsData used in this study were derived from the third wave of a cohort study of a randomized community sample with 4291 participants ≥20 years in 2008 in Lanzhou City and Baiyin City, Gansu Province. Data were collected via face-to-face interview by the trained interviewers. Descriptive analyses, chi-square tests and multivariate logistic regressions were performed by using Stata 12.0, as needed.

ResultsThe prevalence of 12-month suicidal ideation was 4.29 %, there was no significant difference between males and females 5.04 % vs 3.62 %, Adjusted Odds Ratio AOR = 0.83, p = 0.351. Several risk factors for suicidal ideation were confirmed, including being unmarried AOR = 1.55, p = 0.030, having depression symptoms AOR = 2.33, p < 0.001, having other insurance AOR = 1.83, p = 0.01 or no insurance AOR = 1.73, p = 0.024. In addition, several influence factors were significantly different in males and females, such as being currently married unmarried vs married, AOR = 1.84, p = 0.027, for females; no difference for males, feeling hopeless hopless vs hopeful, AOR = 1.92, p = 0.06, for females; no difference for males, having other insurances having other insurances vs having basic employee medical insurance, AOR = 1.92, p = 0.044, for males; no difference for females, having debts having debts vs no debts, AOR = 2.69, p = 0.001, for males; no difference for females, currently smoking smoking vs nonsmoking, AOR = 3.01, p = 0.019 for females, no difference for males, and currently drinking drinking vs nondrinking, AOR = 2.01, p = 0.022, for males; no difference for females.

Discussion and conclusionThese findings suggested that comprehensive suicide prevention strategies should be developed or strengthened in order to prevent suicide ideation in China, and the gender-specific differences need to be explored through further researches.
