“…There have been few studies on the prevalence of asthma and asthma symptoms among Asian countries using a standardized questionnaire. Recently, Fukutomi et al conducted a population-based cross-sectional study of the prevalence of asthma and wheezes by administering the ECRHS questionnaire to Japanese adults (19). They found that the prevalences of asthma and wheezes among Japanese adults aged 27 -79 years were 4.2% (95% CI, 9.7 to 10.5%) and 10.1% (95% CI, 9.7 to 10.5%), respectively.…”

: Objectives : Few reports are available concerning the prevalence of asthma among snow crab workers in Japan. The object of this study was to estimate the prevalence of asthma and wheezes among Japanese snow crab workers and their associations with exhaled nitric oxide (FeNO) and YKL-40. Methods : Forty-nine snow crab workers enrolled in this study, which was cross -sectional by design and was conducted using a translated version of the European Community Respiratory Health Survey questionnaire. The levels of FeNO and serum YKL-40 were measured between September and October 2014. Results : The prevalences of current asthma and wheezes were 10.2% % (95% % CI, 3.4 to 22.2) and 12.2% % (95% % CI, 4.6 to 24.8), respectively. There was no association between these prevalences and the duration of snow crab employment. Six subjects' FeNO levels exceeded 50 ppb, and nine subjects' levels exceeded 25 ppb. Twelve subjects' (25.5% %) serum YKL-40 levels exceeded 77.2 ng/mL, which was 2 standard deviations above the mean for healthy subjects. However, there were no significant relationships among the prevalences for asthma and wheezes, FeNO, and serum YKL-40. Conclusions : This study provides information concerning the prevalences of asthma and wheezes among Japanese snow crab processing workers.

Weather and climate are known to infl uence human health. Seasonal changes of temperature promote alterations in respiratory morbidity and in total and cause-specifi c mortality. Data on the prevalence of asthma and asthma-related symptoms and its disparities between winter and summer in the acid rain-plagued city of Zunyi in southwestern China have not been widely available.In order to describe the epidemiology of asthma and asthma-related symptoms and its prevalence changes between winter and summer, we have completed two cross-sectional surveys of people aged ≥18 years in winter and summer in the inner-city areas of Zunyi city, Guizhou Province, China.The subjects were selected using a simple random sampling method. Data on asthma and asthma-related symptoms and selected home environmental factors were assessed by questionnaire.The studied Chinese adult population residing in Zunyi recorded a lower prevalence rate of asthma than those of Western countries. There was signifi cant difference in asthma prevalence among adult respondents between winter (1.8%) and summer (0.8%) in inner-city Zunyi. Asthma and asthma-related symptoms occurred more frequently in winter than summer, and that difference mainly correlated with environmental risk exposures, including coal combustion, frequency of stove cooking, fan or range hood usage, mattress material, pet possession, must and mould in the bedroom, etc.The prevalence of adult asthma and asthma-related symptoms was higher in winter compared to the summer in Zunyi, China. Our study suggests that asthma may be an important component of the public health burden of indoor air pollution, especially in winter.

“…However, most studies showed that the prevalence of wheezing was almost twice or more than that of defined asthma (6,7). Recently, a Japanese nationwide study, in which we participated, revealed the asthmatic and wheezing prevalence in Japan (8). That study also showed that the prevalence of wheezing was almost twice that of asthmatics.…”

Objective We conducted a cross-sectional study to investigate which factors have a significant impact on wheezing and QOL in the elderly of a Japanese local community. Methods In 2008, 527 participants (250 participants aged 45 to 64 years and 277 participants aged 65 to 88 years) responded to the questionnaire regarding wheezing and disease history. QOL was evaluated by the Short Form-8. The participants underwent airway reversibility testing. The plasma levels of IgE were measured. The plasma levels of N-terminal-pro-B-type natriuretic peptide were measured in twenty-one participants with a history of ischemic heart disease and in thirty-five age-matched participants without that history. Results Wheezing was reported by 50 (9.5%) participants and was associated with a lower score of QOL. In multivariate analysis, wheezing was associated with sex (OR 3.12, CI 1.10-9.67) and a history of bronchial asthma (OR 22.3, CI 6.50-84.0) among participants aged 45 to 64 years. Among participants aged 65 and over, wheezing was associated with a history of bronchial asthma (OR 4.86, CI 1.39-15.1) and ischemic heart disease (OR 5.12, CI 1.61-15.0). Participants with both a history of ischemic heart disease and wheezing showed higher levels of N-terminal-pro-B-type natriuretic peptide. Airway reversibility was only associated with a history of ischemic heart disease (OR 4.65, CI 1.26-17.6). Conclusion It is suggested that bronchial asthma and heart disease are both significant causes of wheezing and affect the QOL in the elderly of a Japanese local community.
