Estimates of the prevalence of chronic pain worldwide and in Canada are inconsistent. Our primary objectives were to determine the prevalence of chronic pain by sex and age and to determine the prevalence of pain-related interference for Canadian men and women between 1994 and 2008.
Using data from seven cross-sectional cycles in the National Population Health Survey and the Canadian Community Health Survey, we defined two categorical outcomes, chronic pain and pain-related interference with activities.
Prevalence of chronic pain ranged from 15.1% in 1996/97 to 18.9% in 1994/95. Chronic pain was most prevalent among women (range: 16.5% to 21.5%), and in the oldest (65 years plus) age group (range: 23.9% to 31.3%). Women aged 65 years plus consistently reported the highest prevalence of chronic pain (range: 26.0% to 34.2%). The majority of adult Canadians who reported chronic pain also reported at least a few activities prevented due to this pain (range: 11.4% to 13.3% of the overall population).
Similar to international estimates, this Canadian population-based study confirms that chronic pain persists and impacts daily activities. Further study with more detailed definitions of pain and pain-related interference is warranted.
全球及加拿大慢性疼痛患病率的估计并不一致。我们的主要目标是确定按性别和年龄划分的慢性疼痛患病率，并确定1994年至2008年间加拿大男性和女性与疼痛相关的干扰的患病率。
利用全国人口健康调查和加拿大社区健康调查七个横断面周期的数据，我们定义了两个分类结果，即慢性疼痛和与疼痛相关的活动干扰。
慢性疼痛患病率从1996/97年的15.1%到1994/95年的18.9%不等。慢性疼痛在女性中最为普遍（范围：16.5%至21.5%），且在年龄最大（65岁及以上）的年龄组中最为普遍（范围：23.9%至31.3%）。65岁及以上的女性一直报告慢性疼痛患病率最高（范围：26.0%至34.2%）。报告患有慢性疼痛的大多数成年加拿大人还报告称，至少有一些活动因此疼痛而受到影响（占总人口的11.4%至13.3%）。
与国际估计相似，这项基于加拿大人群的研究证实慢性疼痛持续存在并影响日常活动。有必要进行更详细的疼痛及与疼痛相关干扰定义的进一步研究。
