A large proportion of the Canadian population lives a sedentary lifestyle. Few data are available describing the physical activity behaviours among specific ethnic groups in Canada, so the purpose of this study is to examine the relationship between ethnicity and the level of self-reported physical activity.
Pooled data from cycles 1.1 (2000/01) and 2.1 (2003) of the cross-sectional Canadian Community Health Survey (ages 20-64 yrs; N = 171,513) were used for this study. Weighted prevalences of self-reported leisure-time moderate (> or = 1.5 kcal x kg(-1) day(-1) (kkd)); moderate to high (> or = 3 kkd) and high physical activity (> or = 6 kkd) were calculated, and multiple logistic regression models were used to quantify the odds of being physically active across ethnic groups, after adjustment for several covariates (White referent group).
The rank order of prevalence of being moderately physically active by ethnicity was: White (49%), Other (48%), NA Aboriginal (47%), Latin American (40%), East/Southeast Asian (39%), Black (38%), West Asian/Arab (36%), South Asian (34%). Aboriginal men and women had the highest prevalences of being physically active at > or = 3 kkd (M = 32%, F = 22%) while East/Southeast Asian (19%) and East Asian/Arab men (19%), and South Asian women (12%) had the lowest prevalences. After accounting for covariates, Aboriginal men were at elevated odds of being physically active compared to Whites (> or = 3 kkd, OR=1.6, p < 0.05; > or = 6 kkd, OR = 2.7, p < 0.05). Only 7% and 3% of Canadian men and women, respectively, were active at > or = 6 kkd.
These results suggest that the prevalence of physically active Canadian adults varies by ethnicity. Strategies to promote physical activity and prevent physical inactivity should consider these findings.
加拿大很大一部分人口的生活方式久坐不动。关于加拿大特定族裔群体身体活动行为的数据很少，因此本研究的目的是探讨族裔与自我报告的身体活动水平之间的关系。
本研究使用了加拿大社区健康调查第1.1轮（2000/01年）和第2.1轮（2003年）的汇总数据（年龄20 - 64岁；N = 171,513）。计算了自我报告的休闲时间中等强度（≥1.5千卡×千克⁻¹×天⁻¹（kkd））、中等至高强度（≥3 kkd）和高强度身体活动（≥6 kkd）的加权患病率，并使用多元逻辑回归模型在调整了几个协变量后（以白人为参照组）量化各族裔群体身体活动的几率。
按族裔划分，中等强度身体活动患病率的排名顺序为：白人（49%）、其他族裔（48%）、北美原住民（47%）、拉丁裔（40%）、东亚/东南亚裔（39%）、黑人（38%）、西亚/阿拉伯裔（36%）、南亚裔（34%）。原住民男性和女性在身体活动强度≥3 kkd时的患病率最高（男性 = 32%，女性 = 22%），而东亚/东南亚裔（19%）、西亚/阿拉伯裔男性（19%）和南亚裔女性（12%）的患病率最低。在考虑协变量后，与白人相比，原住民男性身体活动的几率更高（≥3 kkd，OR = 1.6，p < 0.05；≥6 kkd，OR = 2.7，p < 0.05）。加拿大男性和女性中分别只有7%和3%的人身体活动强度≥6 kkd。
这些结果表明，加拿大成年人身体活动的患病率因族裔而异。促进身体活动和预防身体不活动的策略应考虑这些发现。
