Introduction:

Health-related quality of life (HRQoL) deterioraton is a risk factor for suicide in adults, however, this aspect has been little studied in adolescents.

Objective:

To evaluate the asso ciation between HRQoL (measured with EQ-5D-5L) and suicidal risk in adolescents and its capacity for cross-sectional detection of suicidal risk.

Patients and Method:

128 adolescents (15-19 years old) from Puerto Aysen (Chile) responded to the EQ-5D-5L questionnaire, the Okasha Suicide Scale and two anchoring questions of imminent suicide risk. A suicide risk case was considered to have a > 5 score on the Okasha scale or the affirmative answer to one of the anchoring questions. The index value of EQ-5D-5L was calculated and Odds Ratios (ORs) were estimated with confidence intervals (95% CI), adjusted for confounders. Areas under the ROC curve (AUC-ROC) were calculated to assess the discriminatory performance of EQ-5D-5L.

Results:

21 (16.4%) adolescents were at suicidal risk. Controlling for confounders, the EQ-5D-5L dimensions associated with suicidal risk were pain/ discomfort (OR: 2.5; 95% CI 1.1-6.1) and anxiety/depression (OR: 2.2; 95% CI 1.3-3.6). The AUC- ROC for both dimensions was 85% (95% CI 0.75-0.91) and 81% for the EQ-5D-5L index value (95% CI 0.72-0.89).

Conclusions:

HRQoL could be a risk factor for suicide in adolescents and in this way, the EQ-5D-5L could help in searching for high risk and hidden cases of suicidal risk.
