The ‘Eat Right, Be Positive About Your Body and Live Actively’ (EPaL) intervention programme was developed to prevent overweight and disordered eating in Malaysian adolescents. This study aimed to evaluate the effectiveness of the EPaL programme on knowledge, attitudes and practices on healthy lifestyle and body composition (body mass index z-score [zBMI], waist circumference [WC] and body fat percentage [BF%]) among adolescents. All measures were taken at three time points: before intervention (Pre), after intervention (Post I) and 3 months after intervention (Post II). The intervention group (IG) participated in the EPaL programme for 16 weeks, whereas the comparison group (CG) received no intervention. Seventy-six adolescents (IG: n = 34; CG: n = 42) aged 13–14 years were included in the final analysis. Repeated measures analysis of covariance (ANCOVA) was used to assess the impact of the EPaL intervention programme on the measures between groups (IG and CG) at Post I and Post II. The IG reported significantly higher knowledge scores at both Post I (adjusted mean difference = 3.34; 95% confidence interval [CI] = 0.99, 5.69; p = 0.006) and Post II (adjusted mean difference = 2.82; 95% CI = 0.86, 4.78; p = 0.005) compared with the CG. No significant differences between the IG and CG were found at either Post I or Post II in attitudes, practices, zBMI, WC and BF%. The proportion of participants who were overweight or obese was consistent from Pre to Post II in the IG (35.3%) and increased from 26.2% at Pre to 28.5% at Post II in the CG, but the difference was not statistically significant. The proportion of participants who had abdominal obesity in the IG decreased from 17.6% at Pre to 14.7% at Post II and increased from 16.7% at Pre to 21.4% at Post II in the CG, but the differences were not statistically significant. Despite no significant reduction of body composition, this programme shows the positive effect on the adolescents’ knowledge regarding healthy lifestyle. This study contributes to the evidence on the effectiveness of school-based health interventions in Malaysian adolescents. UMIN Clinical Trial Registration UMIN000024349. Registered 11 October 2016.

以学校为基础的干预措施对马来西亚青少年健康生活方式和身体成分的知识,态度和实践的有效性

制定了“饮食权利,对自己的身体积极和积极生活”(EPaL)干预计划,以防止马来西亚青少年超重和饮食失调。这项研究旨在评估EPaL计划对青少年健康生活方式和身体成分(体重指数z评分[zBMI],腰围[WC]和体脂百分比[BF%])的知识,态度和做法的有效性。所有措施均在三个时间点采取:干预前(之前),干预后(第一阶段)和干预后三个月(第二阶段)。干预组(IG)参加了EPaL计划16周,而对照组(CG)没有接受干预。最终分析中包括了13-14岁的76名青少年(IG:n = 34; CG:n = 42)。重复测量的协方差分析(ANCOVA)用于评估EPaL干预计划对后I和后II组(IG和CG)之间的测量的影响。IG报告在发布I(调整后的平均差异= 3.34; 95%置信区间[CI] = 0.99、5.69; p = 0.006)和发布后II(调整后的平均差异= 2.82; 95%CI = 0.86,与CG相比为4.78; p = 0.005)。在第一阶段或第二阶段,IG,CG的态度,实践,zBMI,WC和BF%均无显着差异。在IG中,从超重或肥胖参与者的比例在IG前(II)到II后(35.3%)是一致的,并且从CG中II(Pre)的26.2%增加到II(Post)的28.5%,但差异无统计学意义。在IG中,腹部肥胖的参与者的比例从Pre之前的17.6%降低到II后的14.7%,从CG前的16.7%升高到II后的21.4%,但差异无统计学意义。尽管身体成分没有明显减少,但该程序显示出对青少年健康生活方式知识的积极影响。这项研究为马来西亚青少年基于学校的健康干预措施的有效性提供了证据。UMIN临床试验注册UMIN000024349。2016年10月11日注册。该计划显示了对青少年健康生活方式知识的积极影响。这项研究为马来西亚青少年基于学校的健康干预措施的有效性提供了证据。UMIN临床试验注册UMIN000024349。2016年10月11日注册。该计划显示了对青少年健康生活方式知识的积极影响。这项研究为马来西亚青少年基于学校的健康干预措施的有效性提供了证据。UMIN临床试验注册UMIN000024349。2016年10月11日注册。
