The immigrant population in Canada is diverse and growing, yet little is known about their physical activity behaviour and how it changes as they adapt to a Canadian lifestyle. This study extends the surveillance of physical activity in Canada to include the influence of time since immigration within and between ethnic groups.
Pooled data from cycles 1.1 (2000/01) and 2.1 (2003) of the cross-sectional Canadian Community Health Survey (ages 20-64 y; N = 171,513) were used for this study. Weighted prevalences of self-reported leisure-time physical activity (> or = 3 kcal x kg(-1) x day(-1) (kkd)) were calculated, and unadjusted and adjusted (age, income, education, BMI) multiple logistic regression models were used to quantify the odds of being physically active (PA) (> or = 3 kkd) by time since immigration (recent immigrant < or = 10 yrs, immigrant >10 yrs, non-immigrant) within and between ethnic groups (White referent group).
The prevalence of recent immigrants (< or = 10 yrs) being PA (> or = 3 kkd) by ethnicity was: White (21%), Other (19%), Black (19%), Latin American (17%), West Asian/Arab (16%), East/Southeast Asian (14%), South Asian (11%). Recent immigrant Black men and White women had the highest prevalence of being PA (M = 27%, F = 18%) while South Asian men and women had the lowest prevalence (M = 14%, F = 9%). There is a gradient in the prevalence of being PA with recent immigrants (16%) < immigrants (20%) < non-immigrants (24%). Ethnic differences in the prevalence of being PA by time since immigration show similar patterns for men and women. Controlling for age, income, education and BMI had only small effects on the odds of being physical active across ethnicities and immigrant status.
These results suggest that physical activity levels vary according to immigrant status and self-ascribed ethnicity in Canadian adults. Strategies to promote physical activity and prevent physical inactivity should consider both ethnicity and time since immigration.
加拿大的移民人口多样且不断增长，但对于他们的身体活动行为以及随着适应加拿大生活方式其行为如何变化却知之甚少。本研究将加拿大身体活动监测范围扩大至涵盖移民时间在不同种族群体内部和之间的影响。
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身体活动（≥3千卡×千克⁻¹×天⁻¹（kkd））的加权患病率，并使用未调整和调整后的（年龄、收入、教育程度、体重指数）多元逻辑回归模型来量化按移民时间（新移民≤10年、移民>10年、非移民）在不同种族群体内部和之间进行身体活动（PA，≥3 kkd）的几率（以白人作为参照组）。
按种族划分，新移民（≤10年）进行PA（≥3 kkd）的患病率分别为：白人（21%）、其他种族（19%）、黑人（19%）、拉丁裔（17%）、西亚/阿拉伯裔（16%）、东亚/东南亚裔（14%）、南亚裔（11%）。新移民中的黑人男性和白人女性进行PA的患病率最高（男性 = 27%，女性 = 18%），而南亚裔男性和女性患病率最低（男性 = 14%，女性 = 9%）。进行PA的患病率存在梯度变化，新移民（16%）<移民（20%）<非移民（24%）。按移民时间划分，不同种族群体进行PA的患病率差异在男性和女性中呈现相似模式。控制年龄、收入、教育程度和体重指数对不同种族和移民身份的身体活动几率仅有微小影响。
这些结果表明，加拿大成年人的身体活动水平因移民身份和自我认定的种族而异。促进身体活动和预防身体不活动的策略应同时考虑种族和移民时间。
