Atopic dermatitis incidence and risk factors in young adults in Castellon (Spain): A prospective cohort study

Abstract

Introduction: There are few atopic dermatitis (AD) incidence cohort studies in young adults, the etiology of this disease remains obscure, and AD risk factors in adults are not well understood. The objective of this study was to estimate AD ten-year incidence and prevalence in a cohort of adolescent aged 14-16 at inception in Castellon province in Valencia Region, Spain and describe related risk factors. Material and methods: From 2002 to 2012, a population-based prospective cohort study was carried out. Questionnaires from the International Study of Asthma and Allergies in Childhood (ISAAC) were used with an additional questionnaire for related factors completed by participants and their parents, respectively, in 2002. In 2012 the same questionnaires were completed by the participants' through a telephone interview, and incidence and prevalence of AD were estimated. Directed acyclic graphs, Poisson regression and inverse probability weighted regression adjustment were used. Results: The participation rate was 79.5% (1435/1805

Atopic Dermatitis and Water: Is There an Optimum Water Intake Level for Improving Atopic Skin?

“…These results were later confirmed by Miyake and colleagues in a cohort study involving children aged 6-7 years, and they speculated that water rich in calcium and magnesium might be involved in the pathophysiological mechanisms of AD [109]. These results were replicated in a Spanish cohort of 6-7-and 13-14-year-old children by Arnedo-Pena and colleagues; however, a significant relationship was observed only in the younger age group [110]. None of these studies investigated the effect of consuming this type of water on AD incidence or exacerbation.…”

Prevalence, incidence and relative risk of cardiovascular disease risk factors in adults with atopic dermatitis: A systematic review

“…Prevalence of active smoking (current and/or former) among patients with AD was reported in 39 studies, with no clear pattern of higher or lower prevalence in AD compared with controls. Prevalence of passive smoking among adults was reported in five studies (AD vs. non‐AD: 0.3% vs. 1.2% in men with ≥1 h of smoking exposure at home, up to 66.7% vs. 67.6% with any exposure at home) 50,54,59,60,75 …”

“…After removing duplicates, 1277 titles/abstracts were screened; of these, 192 full‐text articles were assessed. Of the 71 included studies, 22 were retrospective cohort studies, 5,20–40 36 were cross‐sectional studies, 6,10,19,41–73 seven were prospective cohort studies 74–80 and six were case‐control studies 81–86 (Supporting Information: Table ). Studies were conducted in a broad range of countries in Europe, North America and Asia, with the most numerous being from Denmark and the United States ( n = 14 each).…”

“…Prevalence of passive smoking among adults was reported in five studies (AD vs. non-AD: 0.3% vs. 1.2% in men with ≥1 h of smoking exposure at home, up to 66.7% vs. 67.6% with any exposure at home). 50,54,59,60,75 Fifteen studies reported relative risks related to smoking (Supporting Information: Table S8 and Figure 6); again, there was no clear pattern of increased association between smoking and AD. Two studies examined the risk of developing AD after exposure to active smoking, 54,79 but only one of these reported that the risk was increased.…”

Retrospective survey for clinical course and aggravating factors of adolescent atopic dermatitis in two years' cohort study on first‐year university students

“…To date, there have been few surveys of lifetime AD prevalence in a general population of university students. In Spain, lifetime prevalence within age groups of 14–15 and 24–26 years old was 13.5% and 15.9%, respectively 11 . Incidence of AD in Danish adolescents (15 years old) was 20.4% 12 .…”
