Research on physical activity and fitness indicates their importance in the prevention of disease and promotion of health. However, levels of physical activity have been shown to vary significantly by age, sex and a wide range of additional factors. This paper examines age and sex differences in physical inactivity among 13 to 19 year olds participating in the 1990 Ontario Health Survey. Findings from the bivariate analysis suggest a major increase in physical inactivity between ages 15 and 16. When logistic regression is used to examine the adjusted effects of predictor variables on physical inactivity, the effects of age remain significant. However, the odds of inactivity at one year increments are not significant. There are significant increased odds of inactivity associated with such factors as sex, friends' (activity) participation, perceived future health problems, and perceived health status. The public health implications of the findings suggest that those responsible for developing programs and policies to increase physical activity among teenagers should consider the critical years of decreased activity and the factors that might explain why this decline occurs.
对体育活动和健康状况的研究表明，它们在预防疾病和促进健康方面具有重要意义。然而，体育活动水平已被证明因年龄、性别以及一系列其他因素而存在显著差异。本文研究了参与1990年安大略省健康调查的13至19岁青少年中缺乏体育活动的年龄和性别差异。双变量分析的结果表明，在15岁至16岁之间，缺乏体育活动的情况大幅增加。当使用逻辑回归来检验预测变量对缺乏体育活动的调整效应时，年龄的影响仍然显著。然而，以一年为增量的不活动几率并不显著。与性别、朋友（活动）参与情况、感知到的未来健康问题以及感知到的健康状况等因素相关的不活动几率显著增加。研究结果对公共卫生的影响表明，那些负责制定增加青少年体育活动的项目和政策的人，应该考虑到体育活动减少的关键年龄段以及可能解释这种下降为何发生的因素。
