“…19 Yet other studies found leveling off or even drastically declining rates of psoriasis prevalence for individuals beyond the age of 70 years compared to younger age classes. 17,[21][22][23][24][25] Thus, in contrast to the relatively high prevalence measured herein, a nation-wide telephone survey in Spain applying essentially the same structured questionnaire recorded only 0.33% age-specific prevalence in persons >70 years old. This was only a quarter of the average psoriasis prevalence measured in the whole target population of this latter study or just one seventh of the highest prevalence rate that was found for age 17 Telephone surveys answered by proxies is a reliable and generally valuable source of information about health conditions of older probands.…”

“…27,28 This could at least partly explain thedespite divergent ground populations -unexpected high discrepancy between the estimations of psoriasis prevalence in the elderly found with the same questionnaire in the present face-to-face interview and the former telephone survey study. 17 Furthermore, this observation underscores the difficulties in measuring skin-related morbidity of older probands by using proxies sources, and calls for research focusing on the evaluation of the quality of proxy informations in the area of geriatric dermatology.…”

“…With only one exception, 17 all relevant studies from other geographical regions, report agespecific prevalence rates of psoriasis in individuals >70 years old roughly equal 18,21 to twice as high 19 compared to the mean prevalence in the corresponding whole populations. Accordingly our current measurement for individuals 70-89 years old (3.3%) predicts a mean prevalence of psoriasis for the Greek population of about 1.5-3.0%, which is comparable to that reported from other European regions.…”

“…16 After permission from the Municipal Authorities and following oral consent all individuals, that personally contacted the KAPI medical service between March 01 and April 30, 2010 were interviewed for the presence (active disease) or personal history of psoriasis using a structured questionnaire adapted according to that used previously by Ferrándiz et al in a telephone psoriasis survey in Spain. 17 For the probands, main reasons for attending the medical service of KAPI were to renew prescriptions of routine medications and/or to carry out simple periodic examinations, like blood pressure measurements. The files of all contacted individuals were additionally reviewed for past prescriptions ascribed to the treatment of psoriasis.…”

Knowledge of epidemiological data of psoriasis among elderly people is limited. Herein the prevalence of psoriasis among non-permanently hospitalized, elderly (70-89 year old) individuals was assessed by a face-to-face interview using a structured questionnaire adapted from an earlier telephone survey elsewhere. 450 individuals 70-89 years old consented to contribute. Psoriasis was found in 15/450 individuals [life-long prevalence: 3.33%; (95% confidence intervals: 1.99-5.47%)]; 1/450 individuals have ever required systemic treatment (0.2% [0.01-1.4%]). This prevalence is about ten times higher than corresponding results of the aforementioned telephone survey with the same questionnaire. In conclusion this study: i) Provides the first estimation of psoriasis prevalence in Greece, albeit focused in a particular age group and demonstrates a relatively high life-long prevalence, however with minimal morbidity among older people; ii) Underscores the need for studies to evaluate the impact of proxy effects (e.g. telephone information) in assessing skin morbidity of older probands.

Background and Design: Psoriasis is a chronic inflammatory skin disease affecting nearly 2% of the population. In Turkey, the only data about the prevalence of psoriasis from a population-based study is the data of the prevalence of 0.5% in a small district in a rural area. We aimed to provide the first large-scale data in Turkey by determining the prevalence of psoriasis in a large area, in the central and outlying districts of the province of Trabzon. Materials and Methods: A random sample of 7885 (4057 male and 3828 female) adults was collected by using the stratified sampling technique. The study was performed with face-to-face questionnaire administration with participants selected according to the place of residence, gender and age groups. Psoriasis was diagnosed based on the questionnaires filled by patients during these interviews. Crude psoriasis prevalence ratios and age-adjusted psoriasis prevalence ratios according to the Segi population were calculated and presented with 95% confidence interval (CI). Results: Of 7885 people, 87 were diagnosed with psoriasis, of which 45 were female and 42 were male. The prevalence of psoriasis was found to be 1.1% (95% CI: 0.9-1.3) in the general population. The prevalence of psoriasis in females (1.2%) was higher than that in men (1.0%). Age-adjusted prevalence was 3.9% (95% CI: 3.5-4.3) and 1.0% (95% CI: 0.8-1.2) for females and males, respectively. The presence of a family history of psoriasis increased the psoriasis risk by eight-fold (p<0.001). Conclusion:We found that the prevalence of psoriasis was 1.1% in a large area, in the central and outlying districts of the province of Trabzon. Our study reveals that the prevalence of psoriasis in our country may be lower than that in Northern Europe and North America. Keywords: Psoriasis, prevalence, Turkey Summary Öz Amaç: Psoriasis, toplumun yaklaşık %2'sini etkileyen kronik enflamatuvar bir deri hastalığıdır. Türkiye'de psoriasis prevalansına ait toplum tabanlı tek veri, kırsal alanda ve küçük bir ilçede gerçekleştirilmiş bir çalışmada saptanan %0,5'lik veridir. Bu çalışmada, Trabzon ili ve ilçelerinde, geniş bir alanda psoriasis prevalansını ortaya koyarak, Türkiye'de bu ölçekteki ilk veriyi literatüre kazandırmayı amaçladık. Gereç ve Yöntem: Tabakalı örnekleme metodu ile belirlenen örneklemden 7885 erişkin (4057'si erkek, 3828'i kadın) çalışmaya alındı. Çalışma, yerleşim yerine, cinsiyete ve yaş gruplarına göre seçilen katılımcılar ile yüz yüze anket yöntemi ile gerçekleştirildi. Katılımcılar tarafından yanıtlanan anketlerdeki verilere göre psoriasis tanısı konuldu. Psoriasis prevalansı ve Segi popülasyon kullanılarak yaşa göre düzenlenmiş psoriasis prevalansı hesaplanarak %95 güven aralığı (GA) ile sunuldu. Bulgular: Çalışmamızda örneklem olarak belirlenen 7885 kişiden 45'i kadın, 42'si erkek olmak üzere 87 kişi psoriasis tanısı almıştır. Psoriasis prevalansı %1,1 (%95 GA: 0,9-1,3) olarak saptanmıştır. Kadınlarda psoriasis prevalansı (%1,2), erkeklerden (%1,0) daha yüksekti. Yaşa göre düzeltilmiş prevalans oranl...
