The purpose of this study was to determine the current levels of physical education (PE) and sports participation among American secondary school students, and to establish the extent to which they vary by grade level, racial/ethnic background, and socioeconomic status (SES) of the students.
Nationally representative data were used from over 500 schools and 54,000 students surveyed in 2003, 2004, and 2005 as part of the Youth, Education, and Society (YES) study and the Monitoring the Future (MTF) study. As part of YES, school administrators completed questionnaires on physical activity (including rates of sports and PE participation) of students in their schools. Students in the same schools completed self-administered questionnaires in the same year as part of MTF, providing individual background data, including their gender, racial/ethnic identification, and parents' education level. Data were analyzed in 2006.
Physical education requirements, and actual student participation rates, decline substantially between 8th and 12th grades. About 87% of 8th graders were in schools that required them to take PE, compared to only 20% of 12th graders. Principals estimate that over 90% of 8th graders actually take PE, compared to 34% of 12th graders. Subgroup differences in PE participation rates were small. Only a fraction of all students participate in varsity sports during the school year, with girls participating only slightly less than boys (33% vs 37%). Participation correlates negatively with SES and was lower among black and Hispanic students than white students, even after controlling for other variables. Participation rates in intramural sports were even lower, declined in higher grades, and were lower among low-SES and Hispanic students (after controlling for other variables).
Physical education is noticeably lacking in American high schools for all groups. Racial/ethnic minorities and low-SES youth, who are at higher than average risk of being overweight in adolescence, are getting less exercise due to their lower participation in school sports. Disparities in resources available to minorities and lower-SES youth may help explain the differences in participation rates.
本研究的目的是确定美国中学生目前的体育教育(PE)和体育参与水平,并确定这些水平在学生的年级、种族/族裔背景和社会经济地位(SES)方面的差异程度。
使用了2003年、2004年和2005年对500多所学校和54000名学生进行调查所获得的具有全国代表性的数据,这些数据是青年、教育与社会(YES)研究和未来监测(MTF)研究的一部分。作为YES研究的一部分,学校管理人员完成了关于其学校学生体育活动(包括体育和PE参与率)的问卷。同一学校的学生在同一年作为MTF研究的一部分完成了自填问卷,提供了个人背景数据,包括他们的性别、种族/族裔身份以及父母的教育水平。数据于2006年进行分析。
体育教育要求以及实际学生参与率在8年级到12年级之间大幅下降。约87%的8年级学生所在学校要求他们参加PE,而12年级学生中只有20%所在学校有此要求。校长估计超过90%的8年级学生实际参加了PE,而12年级学生中这一比例为34%。PE参与率的亚组差异很小。在学年中,只有一小部分学生参加校际体育活动,女生参与人数略少于男生(33%对37%)。参与率与SES呈负相关,在控制其他变量后,黑人和西班牙裔学生的参与率低于白人学生。校内体育活动的参与率更低,在高年级下降,并且在低SES和西班牙裔学生中更低(在控制其他变量后)。
美国所有群体的高中体育教育明显不足。种族/族裔少数群体和低SES青年在青春期超重的风险高于平均水平,由于他们较少参与学校体育活动,锻炼也更少。少数群体和低SES青年可获得的资源差异可能有助于解释参与率的差异。
