Abstract

Objective: To evaluate the 6-month impact of a physical activity (PA) multilevel intervention on activity patterns and psychological predictors of PA among adolescents. The intervention was directed at changing knowledge and attitudes and at providing social support and environmental conditions that encourage PA of adolescents inside and outside school.

Subjects and design: Randomised, controlled ongoing field trial (ICAPS) in middle-school's first-level adolescents from eight schools selected in the department of the Bas-Rhin (Eastern France) with a cohort of 954 adolescents (92% of the eligible students) initially aged 11.7+/-0.6 y. The 6-month changes in participation in leisure organised PA (LOPA), high sedentary (SED) behaviour (>3 h/day), self-efficacy (SELF) and intention (INTENT) towards PA were analysed after controlling for baseline measures and different covariables (age, overweight, socioprofessional occupation), taking into account the cluster randomisation design.

Results: The proportion of intervention adolescents not engaged in organised PA was reduced by 50% whereas it was unchanged among control students. After adjustment for baseline covariables, LOPA participation significantly increased among the intervention adolescents (odds ratio (95% confidence interval) (OR)=3.38 (1.42-8.05) in girls; 1.73 (1.12-2.66) in boys), while high SED was reduced (OR=0.54 (0.38-0.77) in girls; 0.52 (0.35-0.76) in boys). The intervention improved SELF in girls, whatever their baseline LOPA (P<10(-4)) and INTENT in girls with no baseline LOPA (P=0.04). SELF tended to improve in boys with no baseline LOPA, without reaching statistical significance. When included in the regression, follow-up LOPA was associated with improvement of SELF in girls (P=0.02) and of INTENT in girls with no baseline PA (P<0.02). The intervention effect was then attenuated.

Conclusion: After 6 months of intervention, ICAPS was associated with a significant improvement of activity patterns and psychological predictors, indicating a promising approach for modifying the long-term PA level of adolescents.

以青少年身体活动和久坐行为(ICAPS)为中心的干预:概念和6个月的结果。
目的:评价体育活动(PA)多层次干预对青少年体育活动模式和心理因素6个月的影响。干预措施的目的是改变知识和态度,并提供社会支持和环境条件,以鼓励在校内外青少年的PA。课题及设计:随机对照正在进行的现场试验(ICAPS)从下莱茵省(法国东部)的八所学校中选择了954名青少年(92%的合格学生),他们最初的年龄为11.7+/-0.6岁。6个月来,参加休闲组织的PA (LOPA)、高久坐(SED)行为(>3小时/天)、考虑到聚类随机化设计,在控制基线测量和不同的协变量(年龄、超重、社会专业职业)后,对PA的自我效能感(SELF)和意向(INTENT)进行分析。结果:参与干预的青少年不参与有组织的PA的比例减少了50%,而对照组学生的比例没有变化。在基线协变量调整后,参与LOPA的青少年显著增加(女孩的优势比(95%置信区间)(OR)=3.38 (1.42-8.05);男孩为1.73(1.12-2.66),女孩高SED降低(OR=0.54 (0.38-0.77);0.52(男孩0.35-0.76)。结论:干预6个月后,ICAPS与活动模式和心理预测因子的显著改善相关,表明了一种有希望改变青少年长期PA水平的方法。
