To Investigate the Prevalence of Children Asthma in China
To Investigate the Prevalence of Children Asthma in China and Compare With That of the Last 20 Years
Asthma is the most common chronic respiratory disease in children and has much effect on their life and study, which leads to huge economic burden and pressure to the whole families. Some children will develop into adult patients so that asthma can be the life-long vigorous trouble. In recent years, the prevalence rate of children asthma is increasingly going up worldwide. The prevalence rate in last 12 months reported in USA, United Kingdom, Australia, New Zealand was between 12% to 30%.
Center for Asthma Prevention and Education of Capital Institute of Pediatrics investigated the national asthma prevalence in 900 thousands children in 27 provinces and cities, which average rate was 0.11% to 2.03% in 1990. In 2000, we investigated it again in 31 provinces(43 cities) and the average national children asthma prevalence rate was 1.97%(0.25% to 4.63%) which was much higher than that in 1990.
