Bullying and health-related quality of life in children and adolescent Mexican students.

Previous studies have reported a relationship between being a victim of bullying, but no studies have been carried out with Mexican students; notwithstanding the high scores of bullying in Mexico in international rankings. The objective of this study was to analyze the association between being a victim of bullying and lower HRQoL among schoolchildren and adolescents in Mexico. This cross-sectional and correlational study involved 2225 students from 22 elementary, middle and high schools. HRQoL was assessed with the KIDSCREEN-10 questionnaire and bullying with the social adaptation dimension of KIDSCREEN-52. Bivariate associations were evaluated, and a multivariate logistic regression was utilized. The prevalence of victims of bullying was 17.3%. Being a victim of bullying was double the risk of having a lower HRQoL than not being a victim after adjusting for health perception, gender and age, OR 2.3 (1.7-3.1). As the Wilson and Cleary Model of Quality of Life explains, individual characteristics, such as, being a victim of bullying are associated with quality of life. Similar findings in the existing literature imply that bullying is a global phenomenon that impacts the victimized child or adolescent's life in different ways.

Resumo Pesquisas prévias informaram que ser vítima de "bullying" se associa à menor Qualidade de Vida Relacionada com a Saúde (QVRS); mas nenhuma foi realizada em estudantes Mexicanos apesar dos altos índices de "bullying" mostrados para o México nos rankings internacionais. O objetivo deste estudo foi analisar a associação entre ser vítima de "bullying" e QVRS. Este estudo transversal e de correlação incluiu 2225 crianças e adolescentes de 22 escolas de nível básico, médio básico e médio superior. A QVRS foi avaliada com o questionário KIDSCREEN-10 e o "bullying" com a dimensão de aceitação social do KIDSCREEN-52. Analisaram-se as associações bivariadas, verificou-se confusão e interação, e utilizou-se regressão logística multivariável. A prevalência de vítimas de "bullying" foi de 17.3%. Ser vítima de "bullying" obteve um risco de mais do dobro de QVRS inferior que não ser vítima, depois de ajustar pela percepção de saúde, gênero e idade, OR 2.3 (1.7-3.1). No mesmo sentido que o referido pelo Modelo de Wilson e Cleary, em estudantes mexicanos com características individuais como ser vítima de "bullying", associam-se à QVRS, descoberta similar ao encontrado na literatura existente o que implica que o "bullying" é um fenômeno global que se reflete em diferentes aspectos da vida em crianças e adolescentes vitimizados.

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.

Comportamientos de riesgo de suicidio y calidad de vida, por género, en adolescentes mexicanos, estudiantes de preparatoria / Suicidal-related behaviors and quality of life according to gender in adolescent Mexican high school students

El estudio de los comportamientos que preceden al suicidio es importante no sólo por su asociación con éste sino por su impacto en la calidad de vida (CV). Dada la escasez de información sobre esta relación en adolescentes, el objetivo de este estudio fue analizar la asociación de los comportamientos de riesgo de suicidio y la CV, según género en adolescentes estudiantes de preparatoria mexicanos. Es un estudio transversal, en participantes de 14 a 18 años de edad. Se utilizó una versión traducida del Youth Risk Behavior Survey y la versión en español del Youth Quality of Life Instrument - Research version. Se aplicaron pruebas no paramétricas. Se pidió consentimiento informado a padres y estudiantes y se obtuvo aprobación de Comité de ética. Se consideró el modelo de desarrollo transaccional del comportamiento suicida de la juventud de Brigde et al. El análisis por separado para mujeres y hombres, mostró los comportamientos de riesgo de suicidio asociados con CV, y fue el comportamiento de haberse sentido triste o sin esperanza, el que presentó en general los tamaños de efecto mayores. Los modelos de regresión evidencian que algunos comportamientos de riesgo de suicidio aumentan la posibilidad de una CV inferior aún después de ajustar por covariables.
