Relationship between socioeconomic position and suicide attempts among the Korean adolescents

This study explored the relationship of the subjective socioeconomic position (SEP) as well as the objective SEP with the rate of suicide attempts in 74,186 adolescents from the 2012 Korea Youth Risk Behavior Web-based Survey (KYRBS). The SEP was measured by the Family Affluence Scale (FAS) and the self-rated household economic status. The low perceived SEP for either the high or low FAS score was related to the elevated likelihood of suicide attempts in both genders. As compared with the adolescents in both the high level of perceived SEP and FAS score after adjusting for other confounding factors, the middle school students were more likely to attempt suicide in both low level of perceived SEP and FAS score (OR, 1.81; 95% CI, 1.18-2.78 for boys, OR, 1.46; 95% CI, 1.13-1.90 for girls). The high school students were more likely to attempt suicide in the low perceived SEP and high FAS score (OR, 1.44; 95% CI, 1.14-1.81 for boys, OR, 1.29; 95% CI, 1.07-1.56 for girls). In conclusion, the relationship of subjective SEP is important in suicide attempts as much as objective SEP and far more important in the high school students.
