A clinical and epidemiological study of psoriasis in Sri-Lanka is presented. The prevalence in the population is estimated to be over 0.4%. The clinic incidence was 8.7%; of these 53.2% were male, and 46.8% female and 8.3% reported a family history of the disease. The mean age at onset was 25.2 years. The frequency distribution for the age at onset was bimodal with peaks at the second and fifth decades. The age at onset was significantly low in females, in patients with a family history of the disease, in those affected by weather changes and in patients whose disease was precipitated by sore throats. The existence of natural subpopulations of patients is suggested. Clinical types and complications of the disease were not essentially different from those observed in the West.
本文介绍了一项关于斯里兰卡银屑病的临床和流行病学研究。据估计，该人群中的患病率超过0.4%。临床发病率为8.7%；其中53.2%为男性，46.8%为女性，8.3%有该病家族史。发病的平均年龄为25.2岁。发病年龄的频率分布呈双峰型，在第二个和第五个十年出现峰值。女性、有家族病史的患者、受天气变化影响的患者以及因喉咙痛而发病的患者发病年龄显著较低。提示存在患者的自然亚群。该病的临床类型和并发症与西方观察到的情况基本没有差异。
