Abstract：
BACKGROUND: Life satisfaction among Korean students is declining substantially, and multifaceted improvement efforts are required.
METHODS: We analyzed longitudinal change trajectories for exercise, grit, and life satisfaction levels among Korean adolescents using latent growth modeling with longitudinal data from the Korean Children and Youth Panel Surveys of 2,142 students (male: 1,070, female: 1,072) from sixth grade (2020) through eighth grade (2022).
RESULTS: The model, which tracked linear changes in the students\' exercise, grit, and life satisfaction, showed consistent declines over three school years for all variables. We also identified a longitudinal causal relationship among exercise, grit, and life satisfaction. A higher grit intercept was associated with higher intercept for-and a partial mediating effect between-exercise and life satisfaction. The grit slope was positively related to the life satisfaction slope, and both the intercept and exercise slope had positive effects on life satisfaction. Moreover, grit had a longitudinal mediating effect between exercise and life satisfaction.
CONCLUSIONS: We discuss the longitudinal change trajectories of exercise, grit, and life satisfaction, the causal and mediating effects among them, and the implications of the findings. These findings bolster our understanding of Korean adolescents\' life satisfaction and have practical significance for designing programs to improve their quality of life.

摘要：
背景：韩国学生的生活满意度正在大幅下降，需要多方面的改进努力。
方法：我们分析了运动的纵向变化轨迹，砂砾,使用潜在增长模型和韩国青少年的生活满意度水平，该模型来自韩国儿童和青年小组调查的2,142名学生（男：1,070，女：1,072），从六年级（2020年）到八年级（2022年）。
结果：模型，跟踪学生练习中的线性变化，砂砾,和生活满意度，在三个学年中，所有变量都显示出持续下降的趋势。我们还确定了运动之间的纵向因果关系，砂砾,和生活满意度。较高的砂砾截距与较高的截距以及运动与生活满意度之间的部分中介作用相关。砂砾斜率与生活满意度斜率呈正相关，截距和运动斜率对生活满意度均有积极影响。此外，砂砾在运动和生活满意度之间具有纵向中介作用。
结论：我们讨论了运动的纵向变化轨迹，砂砾,和生活满意度，它们之间的因果关系和中介效应，以及调查结果的含义。这些发现加强了我们对韩国青少年生活满意度的理解，并对设计计划以提高他们的生活质量具有现实意义。
