To examine the effect of a 6-year school-based intervention program, implemented on the island of Crete, on children's physical activity levels at the end of the intervention and at a follow-up examination 4 years after program's cessation.
Subjects with complete moderate to vigorous physical activity (MVPA) data at baseline, post-intervention and follow-up examination (Academic years 1992-1993, 1997-1998 and 2001-2002 respectively) were included in the analysis [n = 425: Intervention Group (IG): 238; Control Group (CG): 187]. Repeated measures analysis of variance and logistic regression analysis were mainly performed to evaluate the tested hypothesis.
Subject's mean age was 6.3, 11.5 and 15.3 years at baseline, post-intervention and follow-up examination, respectively. MVPA levels were significantly higher for males in the IG than CG at post-intervention (510.2 +/- 404.6 vs. 350.7 +/- 308.0 min/week, P < 0.001) and follow-up (112.3 +/- 78.9 vs. 96.3 +/- 67.0 min/week, P = 0.029). Furthermore, males in the IG were 2.3 (P = 0.011) and 2.1 (P = 0.041) times more likely to meet recommendations for physical activity at the post-intervention and the follow-up examination, respectively, than the CG. No significant findings were observed for females.
The current study indicates a favorable effect of the intervention on boys' physical activity levels, which was maintained 4 years after the end of the program.
研究在克里特岛实施的一项为期6年的校本干预项目，对干预结束时以及项目停止4年后随访检查时儿童身体活动水平的影响。
分析在基线、干预后和随访检查（分别为1992 - 1993学年、1997 - 1998学年和2001 - 2002学年）时具有完整的中度至剧烈身体活动（MVPA）数据的受试者[n = 425：干预组（IG）：238；对照组（CG）：187]。主要进行重复测量方差分析和逻辑回归分析以评估所检验的假设。
受试者在基线、干预后和随访检查时的平均年龄分别为6.3岁、11.5岁和15.3岁。干预后，IG组男性的MVPA水平显著高于CG组（510.2±404.6 vs. 350.7±308.0分钟/周，P < 0.001），随访时也是如此（112.3±78.9 vs. 96.3±67.0分钟/周，P = 0.029）。此外，IG组男性在干预后和随访检查时达到身体活动建议水平的可能性分别是CG组的2.3倍（P = 0.011）和2.1倍（P = 0.041）。女性未观察到显著结果。
本研究表明该干预对男孩的身体活动水平有积极影响，且在项目结束4年后仍得以维持。
