limited data are available on the epidemiologic features of psoriasis in Canada.
to investigate the epidemiologic features and burden of moderate-to-severe psoriasis in a Canadian population.
an online survey was conducted using a consumer panel. Eligible respondents indicated a diagnosis of psoriasis and plaque-type psoriasis of at least moderate severity. Eligibility was validated according to self-reported body surface area (BSA) involvement, sensitive areas affected, and/or current treatment.
of the 514 respondents who completed the survey, 62% estimated a BSA involvement of >/= 3% within the past 5 years. Onset of psoriasis occurred earlier in females than in males. Nail involvement was more commonly reported in individuals with psoriatic arthritis compared to those without. Several symptoms were more likely described as "constantly" or "near constantly" experienced by females than by males. Comorbidities commonly reported were hypertension, dyslipidemia, and overweight or obesity.
the findings are consistent with a substantial burden attributed to moderate-to-severe plaque psoriasis in a Canadian population.
加拿大有关银屑病流行病学特征的数据有限。
调查加拿大人群中中重度斑块状银屑病的流行病学特征和疾病负担。
使用消费者小组进行在线调查。符合条件的受访者表示患有银屑病和至少中度严重的斑块状银屑病。根据自我报告的身体表面积（BSA）受累、受累敏感部位和/或当前治疗情况，对合格性进行了验证。
在完成调查的 514 名受访者中，62%的人估计在过去 5 年内 BSA 受累> / = 3%。女性银屑病发病早于男性。与无银屑病关节炎的患者相比，有银屑病关节炎的患者更常报告指甲受累。一些症状女性比男性更常描述为“持续”或“几乎持续”。常见的合并症包括高血压、血脂异常、超重或肥胖。
这些发现与加拿大人群中中重度斑块状银屑病所带来的巨大负担一致。
