“…In the UK, as elsewhere, there are fewer data available for adults than for children but analyses of a number of studies have shown that there has generally been an increase in DDA in adults [23]. Longitudinal studies of asthma have shown that the use of questionnaire responses related to DDA in adults is affected by recall bias [24]. However, the consistent trends of symptoms observed in this study, the comparability of other studies and the lack of a gold standard for asthma diagnosis suggest that we will continue to rely on such questionnaire data to some extent to estimate trends in asthma.…”

Asthma prevalence has increased worldwide; although less so in developed countries recently. This study assessed changes in the prevalence of asthma and related symptoms in the Busselton community since 1966.Cross-sectional respiratory health surveys of Busselton adults were conducted in 1966, 1969, 1972, 1975, 1981, 1990 and 2005-2007. Logistic regression models were used to estimate prevalence rates of asthma, respiratory symptoms, smoking, airway hyperresponsiveness (AHR) and atopy and to make comparisons in 2005-2007 and previous survey years. Asthma was defined as ever having doctor-diagnosed asthma (DDA).The prevalence of DDA was around 6% from 19666% from to 19756% from , 8% in 19816% from and rose to 19% in 20056% from -20076% from . From 19816% from to 20056% from -2007, smoking prevalence declined and obesity and atopy increased but changes in these variables explained only a small part of the increase in DDA. Wheeze and cough/ phlegm increased but AHR, breathlessness and doctor-diagnosed bronchitis remained relatively stable over the same period.These observations indicate that the increase in DDA is partly explained by increased symptoms and atopy. The lack of changes in AHR and doctor-diagnosed bronchitis suggests that factors such as diagnostic transfer and increased awareness of asthma have also contributed to the rise in prevalence of DDA.
