OBJECTIVE
This paper examines trends in vigorous physical activity participation among students enrolled in grades 7, 9, 11 and 13 in Ontario between 1997 and 2001. Patterns in participation by gender and grade level are also described.
METHODS
Data were derived from the Ontario Student Drug Use Survey for 1997, 1999, and 2001. Three outcomes of vigorous physical activity were included in self-report questionnaires completed by more than 5,000 students over a three-year period. They responded to the survey in classroom groups during school time. Estimates were weighted and variance and statistical tests have been corrected for the complex sample design.
RESULTS
Comparisons between 1997 and 2001 indicated that, overall, patterns of vigorous physical activity remained stable. However, there were significant declines in vigorous physical activity participation by females and 11th grade students between 1997 and 2001.
INTERPRETATION
The trends for females and 11th graders are disturbing, since they indicate that the normal gender and age differences in vigorous physical activity participation, found in numerous previous studies, are compounded by declining levels over time for these groups.
目的
本文研究了1997年至2001年间安大略省7年级、9年级、11年级和13年级学生参与剧烈体育活动的趋势。还描述了按性别和年级划分的参与模式。
方法
数据来自1997年、1999年和2001年的安大略省学生药物使用调查。在三年时间里，超过5000名学生填写的自我报告问卷中包含了剧烈体育活动的三个结果。他们在上课时间以班级小组形式参与调查。估计值经过加权处理，方差和统计检验针对复杂样本设计进行了校正。
结果
1997年与2001年的比较表明，总体而言，剧烈体育活动模式保持稳定。然而，1997年至2001年间，女性和11年级学生参与剧烈体育活动的情况显著下降。
解读
女性和11年级学生的趋势令人不安，因为这表明在许多先前研究中发现的剧烈体育活动参与方面正常的性别和年龄差异，随着时间推移，这些群体的参与水平下降，情况变得更加复杂。
