Abstract
BackgroundThe rise in consultations for asthma or wheezing in primary and hospital care in recent years suggests a progressive increase in the prevalence of this disease, causing morbidity and considerable medical expenses. However, in Honduras no information about the prevalence of asthma and its trends is available. The aim was to determine the prevalence of asthma in the school-aged and adolescent population in several coastal communities in Honduras. MethodsWe performed a multi-centre, observational, cross-sectional study, for which we took a random sample of 805 school-aged children and adolescents between the ages of 6 and 17 years residing in the coastal communities of Coxen Hole, French Harbour, Los Fuertes, Sandy Bay, Punta Gorda, Travesía and Bajamar. The prevalence and severity of asthma were determined using the validated International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire answered by the child's parents. Point and cumulative prevalence were estimated, stratified by ethnic group, community, sex, and family history of asthma. ResultsWe found an overall prevalence of wheezing in the past of 40.5% (95% CI 37.1, 43.9); of wheezing in the last 12 months of 28.0% (95% CI 24.9, 31.1); and have or have had asthma of 31.7% (95% CI 28.5, 34.9). The community with the highest prevalence was Bajamar with 51.0% (95% CI 44.0, 58.0), and in general, the Garifuna ethnic group with 36.5% (95% CI 31.0, 41.9). ConclusionThe prevalence of asthma was higher than in other Latin American regions, with the most cases in participants of African descent, and those with a family history of asthma. The results will provide important data on asthma in Honduras and will contribute to the identification of risk groups.
