The increase in prevalence of asthma and other allergic diatheses has rarely been documented in the developing sub-Saharan countries. We assessed time trends in symptoms of asthma, allergic rhinoconjunctivitis, and atopic eczema among children in lbaclan, Nigeria, with cross-sectional data from 2 International Study of Asthma and Allergies in Childhood questionnaire-based surveys conducted 7 years apart in 1995 and in 2001-2002. The prevalence of current wheeze increased nonsignificantly in the 6- to 7-year age group (4.8%5.5%) and significantly in the 13- to 14-year age group 10.7%-13.0%) (p =.249 and p =.005, respectively). The 12-month prevalence of allergic rhinoconjuctivitis decreased insignificantly in the 6- to 7-year age group (p =.833) but significantly in the 13- to 14-year age group (p =.001), while the diagnosis of atopic eczema decreased in both age groups. The current findings suggest that the symptoms of asthma have only increased significantly in the Nigerian adolescents.
