Physical inactivity is associated with increased risk of mortality and chronic diseases, yet trend information is lacking in most countries. This investigation examines physical activity levels of Canadian adults aged 18 years and older.
Data were collected in six national surveys between 1981 and 2000. Sample sizes ranged from 2,500 to 18,000. Prevalences were tested using Chi-square and Student's t-tests. Socio-demographic correlates were examined using odds ratios adjusted for age, sex, education and income.
Physical activity increased in the 1980s and 1990s among men and women and for all age, education and income groups (p<0.01). Although education differentials narrowed over the period, age differentials widened and income differentials emerged.
The positive trend in Canada is consistent with Finland, but contrary to recent trends for Australia, England and the United States. Despite increases, sedentary living remains a public health issue particularly among women, older adults and lower income groups.
缺乏身体活动与死亡率和慢性病风险增加相关，但大多数国家缺乏相关趋势信息。本调查研究了18岁及以上加拿大成年人的身体活动水平。
在1981年至2000年期间的六项全国性调查中收集数据。样本量从2500至18000不等。患病率采用卡方检验和学生t检验进行检测。使用经年龄、性别、教育程度和收入调整的比值比来研究社会人口统计学相关因素。
在20世纪80年代和90年代，男性和女性以及所有年龄、教育程度和收入组的身体活动均有所增加（p<0.01）。尽管在此期间教育差异缩小，但年龄差异扩大且出现了收入差异。
加拿大的积极趋势与芬兰一致，但与澳大利亚、英国和美国的近期趋势相反。尽管有所增加，但久坐不动的生活方式仍然是一个公共卫生问题，尤其是在女性、老年人和低收入群体中。
