“…The multivariable log-binomial regression model showed a significant association between ETS exposure at home (i.e., presence of 1 or more smokers at home) and atopic dermatitis status after controlling for the effect of gender. Previous studies from China, Germany and Lebanon also reported elevated odds of atopic dermatitis among the schoolchildren if they reported to have been living with smoking family members compared to those who did not have any smoker at home [2,15,17]. The mechanisms by which tobacco smoke affects the skin are poorly understood.…”

“…A report from South Africa used the ISAAC phase III instrument and reported the prevalence of ever-atopic dermatitis and current-atopic dermatitis as 14.1 and 9.6%, respectively, and the corresponding figures were higher among female (16.2 and 12.0%) than male (11.8 and 7.0%) adolescents [16]. A Chinese study reported an 11.8% atopic dermatitis prevalence, somewhat higher among male (12.7%) than female (10.9%) students [17]. These nearly comparable results seem to reflect the use of an identical data collection instrument, i.e.…”

Background: This study aimed to (i) assess the prevalence of exposure to environmental tobacco smoke (ETS) at homes, (ii) assess the prevalence of atopic dermatitis and (iii) evaluate the association between ETS exposure and atopic dermatitis status among adolescents. Methods: During October 2015, a cross-sectional study design was implemented using a self-administered, modified version of the ISAAC (International Study of Asthma and Allergies in Childhood) questionnaire among students enrolled in nine high schools of one of the six governorates of Kuwait. Prevalence of ETS exposure at home (1 or more smokers at home vs. none) and atopic dermatitis were computed. A multivariable log-binomial regression model was used to evaluate the adjusted association between ETS exposure and atopic dermatitis. Results: Of 800 invited students, 746 (93.3%) participated, of whom 74.8% were Kuwaiti and 50.1% were female with a mean (SD) age of 16.8 (0.68) years. Prevalence of ETS exposure at home was 54%. Prevalence of atopic dermatitis was 14.9%. A final multivariable log-binomial regression model showed that compared with the adolescents free from atopic dermatitis, adolescents with atopic dermatitis were significantly more likely to have had ETS exposure at home (adjusted prevalence ratio = 1.49; 95% CI: 1.03–2.14; p = 0.034) or tended to be female (adjusted prevalence ratio = 1.42; 95% CI: 0.99–2.03; p = 0.054). Conclusions: A high prevalence of ETS exposure at home among adolescents was recorded. ETS exposure and female gender were significantly associated with atopic dermatitis status. Intervention fostering voluntary adoption of a smoke-free home rule may help protect the adolescents against ETS exposure and alleviate the menace of associated morbidity.

“…43,48,49 Older studies have not been able to find this association. However, they often use ISAAC criteria to diagnose AD, 33,36,[50][51][52][53][54][55][56] and the most commonly used questions are "Have you ever had an itchy rash which was coming and going for at least 6 months? Have you had this itchy rash at any time in the past 12 months?"…”

Obesity has been associated with atopic dermatitis (AD); however, the results have been conflicting. Our aim was to provide an update on current knowledge from observational studies addressing the possible association between obesity and AD. Systematic literature review was performed by identifying studies addressing a possible link between AD and overweight/obesity from PubMed, EMBASE and the Cochrane Library in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The quality of the included studies was assessed using the Newcastle-Ottawa Scale. A total of 45 studies (comprising more than 90 000 individuals with AD) fulfilled the criteria and were included in the present review. The available studies revealed inconsistencies, but the majority indicated that obesity is associated with AD. Studies addressing obesity in infancy or early childhood (age < 2 years) and AD reported a positive association. From childhood into adulthood, there is a discrepancy in the observations, as the more recent prospective studies found a positive association, whereas this was not observed in older cross-sectional studies. The inconsistency might be explained by the difference in study design, the diagnostic criteria of AD, regional differences, and by the varied definitions of overweight and obesity used in the studies. In Conclusion, overweight/obesity is associated with an increased risk of AD. Large prospective cohort studies are required to confirm the association between AD and obesity and the possibility that weight control in childhood may help to mitigate or reverse AD symptoms.
