Factors influencing suicidal ideation in depressed patients: Based on the 6thkorea national health and nutrition examination survey

Abstract

Suicidal ideation in depressed patients is important related to their life. The purpose of this study was to identify factors influencing suicidal ideation in patients with depression in Korea. This study carried out secondary analysis using data from the 6th Korea National Health and Nutrition Examination Survey (KNHANES). This population-based survey was a nationwide, stratified, multistage, clustered probability design. The subject samples of this study were selected a total of 151 patients who had a major depression among the 7, 380 population. Data were analyzed by using χ2-test, t-test, and logistic regression with the SPSS23.0 and STATA 13.0 program. The average age of a total of 151 depressed patients was 53 years (range 20 to 81). Education (p=.045), subjective health status (p=.001), body discomfort during the past 2 weeks (p=.038), perceived stress (p<.001), depressive mood more than 2 weeks (p<.001), health-related quality of life (p<.001), and hospital accessibility during the past 1 year (p=.005) were statistically significant. To determine the factors affecting suicidal ideation in patients with depression, logistic regression analysis were conducted with only statistically significant variable in the χ2-test and t-test results. As a results, body discomfort during the past 2 weeks (OR=2.53, 95% CI1.29 to 4.95; p=.007), depressive mood more than 2 weeks (OR=10.57, 95% CI3.64 to 30.63; p<.001), health-related quality of life (OR=0.50, 95% CI0.01 to 0.88; p=.007), hospital accessibility (OR=2.33, 95% CI1.06 to 5.13; p=.001) were significantly associated with suicidal ideation in patients with major depression. Depending on the results of this study, tailored interventions for patients with major depression are needed to manage each of the factors affecting suicidal ideation.
