“…The reported asthma cases accounted for 3.4% of our study population, which was higher prevalent than that previously reported in Jinan districts, China (sample aged 0–14 years, 0.7%) [38]. In addition, this study identified a relatively high prevalence of habitual snoring as well (12.2%), compared to 10.9% in Hong Kong children aged 6–12 years [28], 10.0% in French children aged 5 to 6 years [12], and 11.4% in British children aged 4 to 7 years [39].…”

BackgroundPrevious studies have postulated that sleep-disordered breathing (SDB) may be associated with the occurrence and exacerbation of asthma. However, there was limited quantitative evidence on the topic. This study aimed at investigating the prevalence and predisposing factors of asthma, and quantifying the association between SDB and asthma among school-aged children in China. In addition, a comprehensive meta-analysis of the published evidences and our findings were further conducted.MethodsTo test the hypothesis, we conducted a multicentric cross-sectional study involving 22,478 children aged 5–12 years recruited from eight cities in China. Furthermore, a meta-analysis based on both previously published studies and our cross-sectional study was performed.ResultsThe prevalence rate of SDB and asthma was 12.0% and 3.5% among our cross-sectional study sample. It was demonstrated that symptoms of SDB, such as habitual snoring (OR = 1.28, 95%CI: 1.01-1.62), and obstructive sleep apnea (OSA) (OR = 1.92, 95%CI: 1.34-2.76), were significantly associated with asthma, after adjusting for potential confounding factors. In the meta-analysis, SDB was correlated with the prevalence of asthma in both children (OR = 1.58, 95%CI: 1.35-1.80) and adults (OR = 1.55, 95%CI: 1.42-1.67).ConclusionsOur results provide further evidence for the independent association between SDB and asthma. The clinical significance of our findings lies in the emphasis that children undergoing examination or treatment for asthma should be routinely screened for sleep problems. Further systematic study is required to illuminate the underlying mechanism.

“…In two different local population surveys in Korea, current asthma (defined by current wheeze and positive airway hyperresponsiveness) was consistently more prevalent among the elderly (12.7-15.3%) [20, 21]. These age-related increase were similarly observed in several questionnaire-based studies from China [15, 17], Taiwan [37], Mongolia [22], Korea [38], Iran [25], India [8, 11, 28, 31], and Bangladesh [32, 39]. In Japanese nationwide surveys using questionnaires, only wheeze but not physician diagnosed asthma increased with aging [10].…”

“…Specifically, local area prevalence in China was reported as 0.7-3.8% [15, 16, 17, 18, 19]. In two Korean local area studies, current asthma prevalence was 3.6-5.8% when defined by combination of questionnaire and methacholine challenge tests [20, 21].…”

Asia is the world's most dynamic area. Asthma is a major chronic disease in Asia, like other continents. However, unlike childhood asthma, the epidemiological burden of asthma in Asian adults has been unclear. Here we reviewed the currently available literatures on the epidemiology of adult asthma in the Asian community populations. Adult asthma prevalence was generally lower in Asian than in Europe, but the increasing trends suggested the disease burden to rise in the near future. However, for better understanding, it may be essential to prepare for the Asian multinational network for the standardization and collaboration of research.

“…Among 59 935 respondents to the China National Health and Wellness Surveys conducted between 2010 and 2013, 1.99% reported a diagnosis of asthma, with 77.0% considered to have mild asthma based on GINA guidelines . A cross‐sectional survey of 13 645 individuals residing in Jinan, China, revealed that poor asthma control was attributed to suboptimal adherence to the GINA treatment guidelines and underutilization of ICS …”
