title: [Quality-of-life-related factors in adolescents].
abstract: OBJECTIVE
  To determine quality of life (QoL) and its relationship to lifestyles in adolescents in high schools.
  
  
  METHODS
  Cross-sectional, observational study with 256 students aged 12 to 17 in Seville (Spain). Multiple linear regression models were tested (p <0.05).
  
  
  RESULTS
  The boys had higher scores in most of the QoL areas. The female gender was inversely related to physical, psychological, familial QoL areas and the general QoL index. Family functionality and performing physical activity were the factors most associated with better QoL in all areas. All multivariate models were statistically significant and explained from 11% of social QoL variability to 35% of the general QoL index.
  
  
  CONCLUSIONS
  The findings could be useful for developing interventions to promote health in schools, with the objective of promoting healthy lifestyles and QoL.
