Relação entre qualidade de vida e felicidade subjetiva de adolescentes escolares

Abstract

Objective: To assess the quality of life of school adolescents associated with socioeconomic and demographic profiles and the relationship with subjective happiness. Methods: A cross-sectional and quantitative study, developed from December 2018 to January 2019, with 339 adolescents aged 14 to 18 years enrolled at the Federal Institute of Education, Science, and Technology of the Sertao Pernambucano, in Petrolina, Pernambuco. Data related to socioeconomic and demographic profiles (gender, age, income, housing, mother's education, elementary school II, student aid, physical activity, course) were evaluated, so the quality of life was verified using the Kidscreen-27 questionnaire (health and physical activity; psychological well-being; autonomy and relationship with parents; friends and social support; school environment) and subjective happiness using the Subjective Happiness Scale. They estimated crude odds ratios and adjusted by simple and multiple logistic regression models, considering the significance level of 5%. Results: This sample consists of 186 (54.9%) male adolescents and 153 (45.1%) female adolescents, with a mean age of 16.4 years (SD 1.1 year). Male adolescents are 4.10 times (95% CI: 2.31 - 7.26), more likely to have a better quality of life in health. Adolescents in the Electrical Engineering course are 2.27 times (95% CI: 1.02-5.02), more likely to have a better quality of life in health than those in Chemistry (p <0.05). Adolescents with a higher subjective happiness score are 7.10 times (95% CI: 4.18-12.08), more likely to have a better overall quality of life in all domains. Conclusion: Factors such as male gender, physical activity, higher income, younger age, and better subjective happiness positively influenced the quality of life of evaluated adolescents.
