To examine the impact of state- and school district-level policies on the prevalence of physical education (PE) and recess in a nationally representative sample of US public elementary schools.
Analyses from annual, nationally representative, cross-sectional surveys of school administrators in the United States.
Data were collected through surveys conducted between February and June during the 2006-2007 through 2008-2009 school years. State laws and district policies were compiled annually by researchers at the University of Illinois at Chicago using established legal research techniques.
The sample size was 47 states, 690 districts, and 1761 schools.
State- and school district-level PE and recess-related laws.
Twenty minutes of daily recess and 150 min/wk of PE.
The odds of schools having 150 min/wk of PE increased if they were located in states (odds ratio [OR], 2.8; 95% CI, 1.3-5.7) or school districts (OR, 2.4; 95% CI, 1.3-4.3) having a law or policy requiring 150 min/wk of PE. Schools located in states with laws encouraging daily recess were significantly more likely to have 20 minutes of recess daily (OR, 1.8; 95% CI, 1.2-2.8). District policies were not significantly associated with school-level recess practices. Adequate PE time was inversely associated with recess and vice versa, suggesting that schools are substituting one form of physical activity for another rather than providing the recommended amount of both recess and PE.
By mandating PE or recess, policy makers can effectively increase school-based physical activity opportunities for youth.
在美国公立小学具有全国代表性的样本中,研究州和学区层面的政策对体育教育(PE)及课间休息普及率的影响。
对美国学校管理人员进行年度、全国代表性横断面调查的分析。
数据通过在2006 - 2007学年至2008 - 2009学年2月至6月期间进行的调查收集。伊利诺伊大学芝加哥分校的研究人员每年使用既定的法律研究技术汇编州法律和学区政策。
样本包括47个州、690个学区和1761所学校。
州和学区层面与体育教育及课间休息相关的法律。
每日20分钟课间休息和每周150分钟体育教育。
若学校位于有法律或政策要求每周150分钟体育教育的州(优势比[OR],2.8;95%置信区间[CI],1.3 - 5.7)或学区(OR,2.4;95% CI,1.3 - 4.3),则每周有150分钟体育教育的学校的优势增加。位于有鼓励每日课间休息法律的州的学校,更有可能每天有20分钟课间休息(OR,1.8;95% CI,1.2 - 2.8)。学区政策与学校层面的课间休息实践无显著关联。充足的体育教育时间与课间休息呈负相关,反之亦然,这表明学校用一种体育活动形式替代了另一种,而非提供建议量的课间休息和体育教育。
通过强制规定体育教育或课间休息,政策制定者可有效增加青少年基于学校的体育活动机会。
