Evaluate a program promoting exercise and healthy eating among adolescents.
This was a cross-sectional study of 911 adolescents aged 13 to 18 years old in public schools in Goiania, Midwestern Brazil, 2010. The participants were divided into two groups: intervention (schools taking part in the Healthy Living, project) and control. The following were deemed to be exercise: displacement, physical education classes in school, physical activity outside school, and leisure-time physical activity. Pupils who totaled 300 or more minutes per week were defined as active. Consuming protective foods five or more days a week was classified as adequate intake. Statistical analyses made using the Chi-square test.
Most adolescents were identified as inactive or insufficiently active, 65.7% in the Intervention Group and 65.2% Control Group, showing no significant differences between groups, and with higher prevalence among girls. Slightly more than half of adolescents consumed health protective foods 5 or more days a week, 56.6% in the Intervention Group and 50.4% in the Control Group (p = 0.373).
There were no differences between schools in the Intervention Group and Control Group with regard to food choices and physical activity. This indicates that the Healthy Living project needs to be reevaluated to improve the effectiveness in achieving its objectives.
评估一项促进青少年锻炼和健康饮食的计划。
这是 2010 年在巴西中西部戈亚尼亚的公立学校对 911 名 13 至 18 岁青少年进行的一项横断面研究。参与者分为两组：干预组（参与健康生活项目的学校）和对照组。以下被视为运动：位移、学校体育课、校外体育活动和休闲时间体育活动。每周运动 300 分钟或以上的学生被定义为活跃。每周食用 5 天或以上保护食品被归类为充足摄入。使用卡方检验进行统计分析。
大多数青少年被认定为不活跃或活动不足，干预组为 65.7%，对照组为 65.2%，两组之间无显著差异，且女孩的比例较高。略多于一半的青少年每周食用 5 天或以上的健康保护食品，干预组为 56.6%，对照组为 50.4%（p = 0.373）。
干预组和对照组学校在食物选择和体育活动方面没有差异。这表明健康生活项目需要重新评估，以提高实现目标的效果。
