How common is asthma in the Philippines?


There are no available nationwide data published on asthma prevalence. However, the limited reports gathered showed a prevalence of 12% in children aged 13-14 years and 17-22% in older age groups.

Summary of Evidence

Three thousand two hundred and seven children in Metro Manila aged 13-14 years participated in the International Study of Asthma and Allergies in Children (ISAAC). Participants accomplished a 12-month prevalence of self-reported asthma symptoms from written questionnaires and from video questionnaires. The results showed that approximately 12% and 8% prevalence based on responses to the written questionnaires and to the video questionnaires respectively. In a subsequent study, 12.3% of the same population reported wheezing.

A local study estimating the prevalence of asthma and allergies in adults was completed in Malolos, Bulacan in 1998. One thousand five (1,005) adults (ages 18-44 years) were interviewed using a pre-tested questionnaire adapted from the European Community Health Survey (ECHRS) and the ISAAC. The study showed a prevalence of 17.2% for asthma and 49.9% for allergy among adults. Another study conducted at the Lung Center of the Philippines reported a prevalence of 22% in adults.
