Suicidal-related behaviors and quality of life according to gender in adolescent Mexican high school students.

The study of pre-suicidal behaviors is important not only because of their association with suicide but also because of their impact on quality of life (QOL). Given the scarcity of information regarding this relationship in adolescence, the objective of this study was to analyze the association between suicidal-related behavior and QOL according to gender in adolescent Mexican high school students. This cross-sectional study was conducted with participants between 14 and 18 years of age. A translated version of the Youth Risk Behavior Survey and the Spanish version of the Youth Quality of Life Research - Instrument version were used. Non-parametric tests were applied. Informed consent was obtained from parents and students, and ethical committee approval was sought. The developmental-transactional model of suicidal behavior in adolescents by Bridge et al. was used. Separate analyses were conducted for males and females to show the suicidal-related behaviors associated with QOL. The behavior of having felt sad or hopeless generally presented the greatest effect sizes. The regression models showed that some suicidal-related behaviors increase the probability of a lower QOL even after adjusting for covariates.
