Prevalence and characteristics of suicidal ideation among 2199 elderly inpatients with surgical or medical conditions in Taiwan

Table 6 Multivariate logistic regression models exploring items of quality of life related to suicidal ideation

Independent variables	Suicidal ideation (n = 68)
Model 2A for QOL related to SI ^a	AOR	95% CI
QOL Item 15 Mobility	0.60^**	0.42–0.85
Model 2B for QOL related to SI ^b
QOL Item 15 Mobility	0.64^*	0.46–0.90
QOL Item 16 Satisfaction with sleep	0.62^**	0.44–0.88

^*p < 0.05; ^** p < 0.01; AOR adjusted odds ratio
SI suicidal ideation, QOL quality of life rated with WHOQOL-BREF, BSRS Brief Symptom Rating Scale
^aMultivariate analysis: dependent variable: suicidal ideation; independent variables included demographic factors as those in Model 1, BSRS-5 item 2 (depression), BSRS-5 item4 (inferiority), BSRS-5 item5 (insomnia) and all items of QOL-physical health except item 11 and item 17-daily activities which was highly correlated with item 15-mobility (pearson correlation coefficient = 0.73) causing multi-collinearity. Only significant QOL variables were presented in this table
^bMultivariate analysis: except BSRS total score greater than 5 which replaced BSRS-5 item 2, BSRS-5 item 4 and BSRS-5 item 5, all independent variables were the same as those in the Model 1A. Only significant QOL variables were presented in this table
