To study the predictors of change in leisure time physical activity (LTPA) from adolescence to young adulthood.
A nationally representative sample of 3,251 Norwegian students between 12 and 19 years of age were initially surveyed, and follow-up surveys were conducted three times over a 13-year period. The initial response rate was 97%, and retention rates for the three follow-up sessions were 92%, 84%, and 82%, respectively. Four groups of predictors were assessed: sociodemographics, such as gender, age, parental socioeconomic status, pubertal status, and grades; previous LTPA, such as the amount of LTPA and sports club membership; athletic self-concept and depressive symptoms; and other health behaviors, such as smoking, dieting, and body mass. Autoregressive cross-lagged analyses were supplemented with latent growth-curve analyses.
Membership in a sports club and a positive athletic self-concept in adolescence predicted a high level of LTPA in adulthood, whereas smoking tobacco, high BMI, and depressive symptoms in adolescence predicted low levels of LTPA.
Engaging adolescents in organized sports and enhancing adolescents' athletic self-concept may increase the number of adults who are physically active. Preventive efforts to reduce tobacco consumption, obesity, and depression in adolescence may also contribute to an increase in adult LTPA.
研究青少年期至成年期休闲时间体力活动（LTPA）变化的预测因素。
对 3251 名年龄在 12 至 19 岁之间的挪威学生进行了一项全国代表性的抽样调查，并在 13 年的时间内进行了三次随访调查。初始应答率为 97%，三次随访的保留率分别为 92%、84%和 82%。评估了四组预测因素：社会人口统计学因素，如性别、年龄、父母社会经济地位、青春期状况和年级；以往的 LTPA，如 LTPA 量和体育俱乐部会员资格；运动自我概念和抑郁症状；以及其他健康行为，如吸烟、节食和体重。自回归交叉滞后分析辅以潜在增长曲线分析。
青春期时参加体育俱乐部和积极的运动自我概念预测成年时高水平的 LTPA，而青春期时吸烟、高 BMI 和抑郁症状则预测 LTPA 水平较低。
让青少年参与有组织的体育活动和增强青少年的运动自我概念可能会增加成年后积极参与体育活动的人数。在青少年时期减少吸烟、肥胖和抑郁的预防措施也可能有助于增加成年 LTPA。
