Objective: To examine the prevalence and risk factors of psoriasis among rural minority residents in Qiannan prefecture of Guizhou province (Qiannan) and to provide evidences for developing relevant interventions.
Methods: A total of 99 876 minority rural permanent residents ( ≥ 20 years old) were selected with cluster random sampling from Qiannan and surveyed with a face-to-face interview, physical examination, and laboratory tests between January 2016 and October 2017.
Results: Among the participants, totally 1 239 psoriasis cases were diagnosed, with a prevalence rate of 1.24% and a standardized prevalence rate of 1.21%. Multivariate unconditional logistic regression revealed risk factors of psoriasis as following: Buyi nationality (odds ratio[ OR]= 3.411, 95% confidence interval [95% CI: 1.635 – 5.195]), family history of psoriasis ( OR = 3.415, 95% CI: 1.321 – 5.879), overweight/obesity ( OR = 2.933, 95% CI: 1.225 – 3.459), smoking ( OR = 3.215, 95% CI: 1.265 – 5.123), preference for salty food ( OR = 3.901, 95% CI: 1.431 – 4.706), preference for eating chili ( OR = 2.867, 95% CI: 1.245 – 3.782), preference for fish/shrimp food ( OR = 3.157, 95% CI: 1.339 – 5.182), long-term stress or anxiety ( OR = 2.511, 95% CI: 1.142 – 2.998), and living in a slate house ( OR = 3.483, 95% CI: 1.335 – 4.792).
Conclusion: The prevalence rate of psoriasis is relatively high among rural minority adults in Qiannan region of Guizhou province and interventions on risk factors of the disease should be carried out in the population.
[摘 要] 目的 了解贵州省黔南地区农村少数民族居民银屑病患病现状及其危险因素, 为采取相应的干预措施提供参考依据。 方法 于 2016 年 1 月 — 2017 年 10 月采用整群随机抽样方法在贵州省黔南地区抽取 99 876 名 ≥ 20 岁农村常住少数民族居民进行问卷调查、体格检查和实验室检测。 结果 贵州黔南地区 99 876 名常住农村少数民族居民中, 患银屑病者 1 239 例, 患病率为 1.24 %, 标化患病率为 1.21 %; 多因素非条件 logistic 回归分析结果显 示, 布依族 ( OR = 3.411, 95 % CI = 1.635~5.195) 、有家族史 ( OR = 3.415, 95 % CI = 1.321~5.879) 、超重/肥胖 ( OR = 2.933, 95 % CI = 1.225~3.459) 、吸烟 ( OR = 3.215, 95 % CI = 1.265~5.123) 、咸类食物 ( OR = 3.901, 95 % CI = 1.431~4.706) 、喜食辣椒 ( OR = 2.867, 95 % CI = 1.245~3.782) 、喜食鱼虾 ( OR = 3.157, 95 % CI = 1.339~5.182) 、长期紧张或焦虑 ( OR = 2.511, 95 % CI = 1.142~2.998) 和石板房建筑 ( OR = 3.483, 95 % CI = 1.335~4.792) 是贵州黔南地区农村少数民族居民银屑病患病的危险因素。 结论 贵州黔南地区农村少数民族居民银屑病患病率较高, 应针对该地区少数民族居民银屑病患病的危险因素进行干预。
