BACKGROUND
In Canada, data show adults had a lower energy intake in 2004 than in 1972. Data also show adults expended more energy through leisure-time physical activity in 2000 than in 1981. On the other hand, the prevalence of overweight and obesity (combined) rose from 49.2% to 59.1% between 1978 and 2004.
PURPOSE
This study aimed to chart trends in leisure-, transport-, and work-related physical activity in Canada between 1994 and 2005.
METHODS
We used nationally representative data from the three National Population Health Surveys (1994, 1996, and 1998) and the three Canadian Community Health Surveys (2000, 2003, and 2005) (a repeated cross-sectional design). Sample sizes ranged from n=17626 (in 1994) to n=132,221 (in 2005).
RESULTS
Between 1994 and 2005, men became less inactive during leisure time (-9.94% [9.89%-9.98%]), less inactive during transports (-15.31% [15.26%-15.35%]), and more inactive at work (+5.18% [5.14%-5.22%]). Similar results were found for women.
CONCLUSIONS
Declining levels of physical activity at work may help explain the rising prevalence of overweight and obesity in Canada.
背景
在加拿大，数据显示成年人在 2004 年的能量摄入低于 1972 年。数据还显示，成年人在 2000 年的休闲时间体育活动中消耗的能量比 1981 年更多。另一方面，超重和肥胖（合并）的患病率从 1978 年到 2004 年从 49.2%上升到 59.1%。
目的
本研究旨在描述加拿大在 1994 年至 2005 年期间与休闲、交通和工作相关的体育活动趋势。
方法
我们使用了三个全国人口健康调查（1994 年、1996 年和 1998 年）和三个加拿大社区健康调查（2000 年、2003 年和 2005 年）的全国代表性数据（重复横断面设计）。样本量从 n=17626（1994 年）到 n=132221（2005 年）不等。
结果
1994 年至 2005 年间，男性在休闲时间的活动量减少（-9.94%[9.89%-9.98%]），在交通活动量减少（-15.31%[15.26%-15.35%]），在工作中的活动量增加（+5.18%[5.14%-5.22%]）。女性也有类似的结果。
结论
工作中体力活动水平的下降可能有助于解释加拿大超重和肥胖患病率的上升。
