To investigate the independent and combined effects of lifestyle behaviors, including physical activity, sedentary behavior, sleep duration and food intake, in the health-related quality of life (HRQoL) of Brazilian adolescents.
Cross-sectional school-based study, with the participation of 306 adolescents aged 14 to 18 years. A questionnaire was applied with structured questions to collect lifestyle behaviors data. Perception of the HRQoL was identified using the Kidscreen-27. The study used covariance analysis and linear regression models for statistical analysis.
Adolescents who reported ≤ 2 hours/day of screen-based sedentary behavior and sleep duration equivalent to 8-10 hours/night presented significantly higher HRQoL. Adolescents who reported joint adherence ≥ 3 healthy lifestyle behaviors demonstrated approximately two [OR=2.12] to three times [OR=3.04] more chance of presenting higher perceptions of HRQoL.
Although healthy lifestyle behaviors had a positive independent effect on HRQoL, joint adherence to healthy behaviors enhances the cumulative effect.
探讨包括身体活动、久坐行为、睡眠时间和饮食摄入在内的生活方式行为对巴西青少年健康相关生活质量（HRQoL）的独立和综合影响。
这是一项横断面的基于学校的研究，共有 306 名 14 至 18 岁的青少年参与。采用问卷调查收集生活方式行为数据。使用 Kidscreen-27 评估 HRQoL 感知。研究采用协方差分析和线性回归模型进行统计分析。
报告每天屏幕久坐行为时间≤2 小时且睡眠时间相当于 8-10 小时/晚的青少年，其 HRQoL 明显更高。报告联合坚持≥3 种健康生活方式行为的青少年，表现出更高 HRQoL 感知的可能性约为两倍[OR=2.12]至三倍[OR=3.04]。
尽管健康的生活方式行为对 HRQoL 有积极的独立影响，但联合坚持健康行为可增强累积效应。
