Recent research has reported that there are many effects of climate change on allergic disease in humans. The aim of this study was to clarify evidence of the effects of climate change on the prevalence of allergic disease. We reviewed the available evidence of the relation between climate factors and allergic disease. And a systematic online and manual literature search to the theme "allergies and climate change" was made for model-derived keywords.

OBJECTIVES: Childhood allergic diseases are a major concern because they lead to a heavy economic burden and poor quality of life. The purpose of this study was to investigate the prevalence of childhood atopic dermatitis, asthma, allergic rhinitis, and the comorbidity of allergic diseases in Seoul, Korea. METHODS: We conducted a cross-sectional survey between May and October 2010 to evaluate the prevalence of childhood allergic diseases, including atopic dermatitis, asthma, and allergic rhinitis, using a questionnaire from the International Study of Asthma and Allergies in Childhood group. Each questionnaire was completed by the parent or guardian of a child. RESULTS: In the 31,201 children studied, the prevalence of atopic dermatitis symptoms in the past 12 months was 19.3% in children 0 to 3 years of age, 19.7% in children 4 to 6 years of age, 16.7% in children 7 to 9 years of age, and 14.5% in children 10 to 13 years of age (p for trend < 0.001). The prevalence of asthma in these age groups was 16.5%, 9.8%, 6.5%, and 5.4%, respectively (p for trend < 0.001). The prevalence of allergic rhinitis in these age groups was 28.5%, 38.0%, 38.5%, and 35.9%, respectively (p for trend = 0.043). The percentage of subjects with both atopic dermatitis and asthma, both asthma and allergic rhinitis, or both atopic dermatitis and allergic rhinitis was 2.5%, 4.7%, and 8.7%, respectively. The prevalence of comorbid allergic diseases decreased with age (p for trend < 0.001). CONCLUSIONS: Our study revealed that the prevalence of some allergic diseases, such as atopic dermatitis and asthma, was relatively high in very young children and that all of the principal allergic diseases in children often co-exist.

PURPOSE: In this study, we attempted to analyze the effectiveness of the atopic dermatitis camp for primary school students in the Seoul area. METHODS: Seoul city's atopy camp 2010 was conducted 10 times from May 22nd to October 24th for primary school students at an atopy friendly school and their parents. A total of 374 atopic dermatitis patients participated in the camp and questionnaires for 363 were analyzed, except 11 participants who had left several questions unanswered. In a 3-month follow-up survey, 167 participants out of 374 responded to the mailing questionnaire to evaluate the efficiency of the camp. The response rate was 44.7%. RESULTS: Satisfaction with the educational program of the camp was higher for lower grade students than for higher grade students.(P<0.001) Before camp, higher grade students (P<0.001) or students with severe symptoms were more knowledgeable of atopic dermatitis.(P<0.01) After the camp, the higher the grade, the more the knowledge the student had about atopic dermatitis.(P<0.001) Three months after the camp, there was positive change in the lifestyle of atopic dermatitis patients.(P<0.001) CONCLUSION: Knowledge on atopic dermatitis increased and the lifestyle of atopic dermatitis patients was improved due to the camp. Consequently, Seoul city's atopy camp can be utilized as a method to improve the quality of life of atopic dermatitis patients and their family. And Seoul city's atopy camp is expected to be a model for atopy camps in other local communities.

OBJECTIVES: The aim of this study was to elucidate the relationship between occupational stress and risk factors for cardiovascular diseases. METHOD: The study subjects were 169 male workers aged over 40 who were employed in the shipbuilding industry. A self-reported questionnaire was used to assess the respondents' sociodemographics and occupational stress. Eight domains of occupational stress according to the Korean Occupational Stress Scale (KOSS) were used. We included blood pressure, lipid level (total cholesterol, triglyceride, HDL cholesterol), coagulation factors, pulse wave velocity and heart rate variability as possible cardiovascular risk factors. RESULT: In multiple regression analyses, job demand was associated with triglyceride level, pulse wave velocity and heart rate variability. Interpersonal conflict was related to total cholesterol. Job insecurity was related to heart rate variability. Organizational system was associated with blood pressure, total cholesterol, pulse wave velocity and heart rate variability. Lack of rewards was related to systolic blood pressure and pulse wave velocity. CONCLUSIONS: These results indicate that occupational stress is associated with cardiovascular risk factors.
