@entity565 and atopy prevalence patterns in the developing world are only beginning to be defined. No such information exists for Vietnam. Estimates would assist in anticipating health service needs as well as add to the growing database on global patterns of atopy. To estimate the prevalence of @entity1109 in school @entity1 in Ha Noi, Vietnam, a cross-sectional survey was conducted of @entity1 aged 5- to 11-years-old in two schools using the parent self-administered International Study of @entity566 in Childhood (ISAAC) questionnaire. The response rate was 66.4% (969 responses). The overall prevalence of selected symptoms were: 'ever wheezed' 24.9%, 'wheezed in past 12 months' 14.9%, 'ever had @entity565 ' 12.1%, 'doctor-diagnosed @entity565 ' 13.9%, 'ever experienced @entity2023 ( @entity2023 ) symptoms' 34.9%, ' @entity2023 - @entity2024 symptoms in past 12 months' 10.7%, 'ever had @entity2023 ' 7.8%, 'doctor-diagnosed @entity2023 ' 11.2%, 'ever had @entity484 ' 3.3% and 'doctor-diagnosed @entity484 ' 3.2%. Kappa statistics demonstrated high within symptom category consistency for 'ever had @entity565 /doctor-diagnosed @entity565 ' (0.728) and 'ever had @entity484 /doctor-diagnosed @entity484 ' (0.906). Age and gender adjusted odds ratios (OR) were also consistently significant across wheeze and @entity2023 symptom categories [highest OR = 10.10 (95% CI 6.23-16.35) between @entity56 and wheeze in past 12 months]. There is a high prevalence of ISAAC-based symptoms in school @entity1 in Ha Noi, Vietnam, often above global averages. The high level of association between @entity1109 suggests some degree of reliability and validity. Childhood atopy symptom prevalence in Vietnam is more similar to that in developed countries rather than developing countries.
