The 2002 prevalence estimates of 3.0–6.0% for Asia‐Pacific nations are lower compared with Western countries, although prevalence in Asia appears to be on the rise. This increase has been attributed to environmental exposures, with children and the elderly at highest risk.Thirty million people in China are affected by asthma. A household survey of more than 180 000 individuals 14 years or older residing in eight provinces of China revealed an overall asthma prevalence of 1.2%, while other studies report a prevalence of 1.1% across all age groups. Prevalence is higher in urban areas at 1.4% versus 0.9% for rural locations. Crucially and consistent with trends in other Asia‐Pacific countries, asthma prevalence in China appears to be increasing.Treatment goals include optimal symptom control, maintenance of normal activity levels and reductions in exacerbations and fixed airflow limitations, with minimal side effects. Pharmacological treatment options are guided by severity. Mild asthma is asthma that is well controlled with Step 1 or Step 2 treatment
