Objective To investigate the prevalence of bronchial asthma in population of Guangdong in northern Guangdong in 1998, explore the risk factors of asthma and understand the patients’ knowledge of asthma. Methods A stratified cluster unequal ratio random sampling method was used to investigate 24 618 people in Longxian and Wengcheng townships in Wengyuan County, Shaoguan City of northern Guangdong. Results The prevalence rate of total population in northern Guangdong was 0-410%, of which the prevalence rate was 0-287% in children, 0-459% in adults, and 1-24:1 in males and females. The prevalence rate in the elderly group was 1 -370%. A risk factor survey found that 92-1% were induced by a cold and 62-4% were induced by exposure to stimulus gases. Overworking in agriculture is also a common cause. Conclusion This survey basically represents the prevalence of bronchial asthma in northern Guangdong. The data provide the basis for future prevention and treatment of mass group and related research.
