Rural/urban background, depression and suicidal ideation in Chinese college students: a cross-sectional study.

Abstract

OBJECTIVES: The objective of this study was to examine, first, the relationship of having a rural vs. urban background with suicidal ideation in Chinese college students, and second, whether a potential relationship was mediated by depression. METHODS: A survey was conducted among 1,145 undergraduate students at a university in China. Suicidal ideation and depressive symptoms were measured by the revised Hopkins' Symptom checklist (SCL-90-R). Associations between rural vs. urban background, depression and suicidal ideation were estimated by multivariable linear regression-based β coefficients, logistic regression-based odds ratios (ORs), and corresponding 95% confidence intervals (CIs). The magnitude of indirect effect and bias-corrected 95% CIs were obtained through bootstrap techniques. RESULTS: Rural background was positively associated with depression, which was in turn associated with suicidal ideation. The OR for rural status and suicidal ideation equaled 2.15 (95% CI = 1.36-3.41). This OR was slightly, though significantly (p<0.05) attenuated by additional adjustment for depressive symptoms (OR = 1.99, 95% CI = 1.15-3.44). CONCLUSION: Having a rural background is a determinant of suicidal ideation in Chinese college students. Depression may only marginally mediate this association.
