“…One explanation for our findings is that even though the prevalence of eczema symptoms are showed to be higher among younger children in previous studies, the severity of these symptoms have been found to increase over time since eczema became exacerbated with increased age . Another possible explanation could lie in recent studies’ findings that higher prevalence of ES was found among children who had experienced a natural disaster . The majority of older children in the present study might have experienced the 2004 tsunami in Aceh in a very early age, whereas younger children did not experience it.…”

IntroductionExact etiology and proper treatment of eczema are still unknown. The hygiene hypothesis and epidermal barrier dysfunction hypothesis attempted to give some plausible explanations for these issues but they still remain unclear. The identification of factors, including hygiene practices, related to eczema symptoms (ES) could shed some light on these matters. Therefore, this study aimed to determine risk factors related to ES and the ES prevalence in two disparate areas in terms of urbanization in Aceh, Indonesia.MethodsA cross‐sectional study with convenience sampling was conducted among schoolchildren living in urban and rural Aceh. Data on ES, socio‐demographic characteristics, environmental factors, partial ablution and other hygiene related factors were collected by parental questionnaires. In addition, children's anthropometric measurements were also collected.ResultsThe prevalence of current ES in the study population was 21%. When stratifying by residency, the prevalence of ES in urban and rural area was 20.93% versus 21.05%. Partial ablution was independently associated with a reduced risk of ES (OR = 0.36; 95% CI 0.13–0.96). Important risk factors for ES were paternal history of allergic disease (OR = 4.09%; 95% CI 1.51–11.11) and belonging to the older group of schoolchildren (10–13 years old) (OR = 2.57; 95% CI 1.03–6.40).ConclusionsThere were no significant differences in the prevalence of ES between urban and rural settings, and partial ablution had a protective effect on ES. These findings support the epidermal barrier dysfunction hypothesis as a possible pathway of eczema.

“…Furthermore, we did not include school-aged children, whose developmental stage might be different from that of preschool children, in our survey. In a previous study, Miyashita et al 24 reported that the prevalence of eczema symptoms among children in the second and eighth grades after the Great East Japan Earthquake was higher compared with the average in Japan, and experiencing the ‘tsunami’ was significantly associated with a high prevalence of eczema. Our results might support the possibility that children overall who experience a mega disaster could experience negative health effects.…”

ObjectiveTo investigate the relationship between personal experience of the Great East Japan Earthquake and various disease types among nursery school children.DesignWe conducted a nationwide survey of nursery school children born between 2 April 2006 and 1 April 2007. Nursery school teachers completed questionnaires if they agreed to join the study. Questionnaire items for children consisted of their birth year and month, sex, any history of moving into or out of the current nursery school, presence of diseases diagnosed by a physician at the age of 66–78 months and type of disaster experience. The survey was conducted from September 2012 to December 2012.SettingJapan, nationwide.ParticipantsA total of 60 270 nursery school children were included in the analysis, 840 of whom experienced the disaster on 11 March 2011.Main outcome measuresThe health status of children 1.5 years after the disaster based on nursery school records.ResultsExperiencing the disaster significantly affected the prevalence of overall and individual diseases. Furthermore, there was a difference in disease prevalence between boys and girls. In boys, experiencing the tsunami (OR 2.53, 95% CI 1.22 to 5.24) and living in an evacuation centre (OR 2.92, 95% CI 1.46 to 5.83) were remarkably associated with a higher prevalence of atopic dermatitis, but these trends were not observed among girls. Instead, the home being destroyed (OR 3.50, 95% CI 2.02 to 6.07) and moving house (OR 4.19, 95% CI 2.01 to 8.71) were positively associated with a higher prevalence of asthma among girls.ConclusionsOur study indicates that experiencing the disaster may have affected the health status of nursery school children at least up to 1.5 years after the disaster. Continuous monitoring of the health status of children is necessary to develop strategic plans for child health.

Background Securing food for patients with food allergies may be more difficult during disasters, but reports on the status of household allergen‐free food reserves in preparation for disasters are limited. This study investigated the household stock status of allergen‐free foods in preparation for disasters in Kobe City after the Great Hanshin‐Awaji Earthquake. Methods The survey targets were 172 parents of patients with a food allergy who underwent in‐hospital oral food challenge test for allergies at four hospitals from October 2016 to March 2017. Of these, 158 patients with allergies to eggs, milk and wheat were included in the analysis. The first survey was performed to investigate patient characteristics and stockpiling status of allergen‐free foods in parallel with oral food challenge tests. The second survey was performed on the follow‐up visit to investigate any changes in behavior. Results Median patient age was 3 years, with boys comprising 68.4% of the patients. Eggs were the most eliminated food, and the median number of foods avoided was 2. A total of 82.3% of parents had experienced disasters. The proportion of households that stockpiled allergy‐free meals was 42.4%, and the median amount was 3 days. The stockpiling situation did not differ according to the parents’ disaster experience. In the second survey, 45.3% had modified their stockpiling practice. Conclusions Even in this area where the Great Hanshin‐Awaji Earthquake occurred, household stockpiles of allergen‐free foods are inadequate; therefore, all medical staff should educate families about the necessity of stocking allergen‐free food for disasters.
