Studies investigating changes in the general population over time concerning adolescent self-reported Quality of life (QoL) are sparse. The aim of this study is to investigate stability and change over more than a decade in self-reported QoL, emotional problems, and negative stressful life-events among students. Three large cross-sectional samples (N = 1032, 4744 and 3826) of 13–17-year-old adolescents attending public school in the Norwegian County of Trøndelag provide data, one from 2017 to 2019 and two from 11 and 13 years earlier. We analyzed linear and binary linear regression adjusted for age. We found few indications of large changes in overall QoL. The exception was a 50% increase in reported emotional problems in both girls and boys. Girls also reported an increase of sexually uncomfortable/abusive acts from peers from 3.7 to 7.0%. The observed changes must be addressed through public health interventions targeting school as an important arena.

关于青少年自我报告的生活质量 (QoL) 随时间推移而调查一般人群变化的研究很少。本研究的目的是调查十多年来学生自我报告的生活质量、情绪问题和消极压力生活事件的稳定性和变化。在挪威特伦德拉格县就读公立学校的 13-17 岁青少年的三个大型横断面样本（N = 1032、4744 和 3826）提供了数据，一个来自 2017 年至 2019 年，两个来自 11 年前和 13 年前。我们分析了根据年龄调整的线性和二元线性回归。我们几乎没有发现整体 QoL 发生重大变化的迹象。例外是女孩和男孩报告的情绪问题增加了 50%。女孩还报告说，来自同龄人的性不适/虐待行为从 3.7% 增加到 7.0%。
