Abstract Objective: To determine the prevalence of allergic rhinitis and associated factors in adolescents and in their parents/guardians. Methods: A cross-sectional study, applying a standardized and validated written questionnaire. Adolescents (13–14 years old; n=1,058) and their parents/guardians (mean age=42.1 years old; n=896) living in the city of Uruguaiana, southern Brazil, responded to the Global Asthma Network standard questionnaires. Results: The prevalence of allergic rhinitis in adolescents was 28.0%, allergic rhinoconjunctivitis, 21.3%, and severe forms of allergic rhinitis, 7.8%. In the adults, the prevalence of allergic rhinitis was 31.7%. Some associated factors with allergic rhinitis in adolescents include low physical exercise (OR 2.16; 95%CI 1.15–4.05), having only one older sibling (OR 1.94; 95CI 1.01–3.72) and daily meat consumption (OR 7.43; 95% CI 1.53–36.11). In contrast, consuming sugar (OR 0.34; 95%CI 0.12–0.93) or olive oil (OR 0.33; 95%CI 0.13–0 .81) once or twice a week, and eating vegetables daily (OR 0.39; 95%CI 0.15–0.99) were considered factors negatively associated. In adults, exposure to fungi at home (OR 5.25; 95%CI 1.01–27.22) and consumption of meat once or twice a week (OR 46.45; 95CI 2.12–1020.71) were factors associated with the medical diagnosis of allergic rhinitis, while low education (OR 0.25; 95%CI 0.07–0.92) was found to be a factor negatively associated. Conclusions: The prevalence of allergic rhinitis in adolescents is high, as well as its medical diagnosis in adults living in Uruguaiana. Environmental factors, especially food habits, were associated with findings in both groups.

Resumo Objetivo: Determinar a prevalência de rinite alérgica e fatores associados em adolescentes e em seus pais/responsáveis. Métodos: Estudo transversal, com aplicação de questionário escrito padronizado e validado. Adolescentes (13–14 anos; n=1.058) e seus pais/responsáveis (média de idade=42,1 anos; n=896) residentes na cidade de Uruguaiana, Sul do Brasil, responderam aos questionários padrão da Global Asthma Network. Resultados: A prevalência de rinite alérgica em adolescentes foi de 28,0%, a de rinoconjuntivite alérgica foi de 21,3% e a de formas graves de rinite alérgica, de 7,8%. Nos adultos, a prevalência de rinite alérgica foi de 31,7%. Alguns fatores associados à rinite alérgica em adolescentes incluem fazer pouco exercício físico (odds ratio — OR 2,16; intervalo de confiança — IC95% 1,15–4,05), ter apenas um irmão mais velho (OR 1,94; IC95% 1,01–3,72) e consumir carne diariamente (OR 7,43; IC95% 1,53–36,11). Por outro lado, consumir açúcar (OR 0,34; IC5% 0,12–0,93) ou azeite de oliva (OR 0,33 IC95% 0,13–0,81) uma ou duas vezes por semana e comer vegetais diariamente (OR 0,39; IC95% 0,15–0,99) foram considerados fatores associados negativamente. Em adultos, a exposição a fungos no domicílio (OR 5,25; IC95% 1,01–27,22) e o consumo de carne uma ou duas vezes por semana (OR 46,45; IC95 2,12–1020,71) foram fatores associados ao diagnóstico médico de rinite alérgica, enquanto a baixa escolaridade (OR 0,25; IC95% 0,07–0,92) se mostrou como fator associado negativamente. Conclusões: A prevalência de rinite alérgica em adolescentes é alta, assim como seu diagnóstico médico em adultos residentes em Uruguaiana. Fatores ambientais, especialmente hábitos alimentares, foram associados aos achados em ambos os grupos.

Abstract Background: Allergic Rhinitis and its Impact on Asthma (ARIA) establishes guidelines for the treatment of allergic rhinitis (AR) and its comorbidities. Objective: To assess and compare the level of knowledge about AR and ARIA guidelines among primary care physicians (PCP) of Brazil, Paraguay and Uruguay. Methods: 336 PCPs (Brazil 109, Paraguay 127, Uruguay 100) answered a questionnaire about personal and professional data and knowledge on RA and the ARIA guidelines; the Google Forms tool was used. Results: There was a predominance of females (73, 50.4 and 70 % in Brazil, Paraguay and Uruguay, respectively); 124 worked in the community and 75 in emergency departments. Brazil and Uruguay PCPs recognized AR symptoms; 67 % of those from Uruguay did not ask about a history of AR diagnosis, 93 % about an asthma diagnosis and 90 % about rhinitis interference with daily activities. Intranasal corticosteroids use: 78, 92 and 54 % of Brazilian, Paraguayan and Uruguayan doctors; 100, 73.4 and 78 % of Paraguayan, Brazilian and Uruguayan PCPs, respectively, did not refer the patient to a specialist; 26.6, 62 and 6 % of PCPs in Brazil, Paraguay and Uruguay, respectively, knew the ARIA guidelines. Conclusions: AR is commonly looked after by PCPs, but the recognition of symptoms and knowledge about ARIA guidelines are low and treatment is not always optimal.

Resumen Antecedentes: En ARIA se establecen directrices para el tratamiento de la rinitis alérgica y sus comorbilidades. Objetivo: Evaluar y comparar el nivel de conocimiento sobre rinitis alérgica y la guía ARIA en médicos de atención primaria (MAP) de Brasil, Paraguay y Uruguay. Métodos: 336 MAP (Brasil 109, Paraguay 127, Uruguay 100) respondieron un cuestionario sobre datos personales, profesionales y conocimiento en rinitis alérgica y ARIA; se utilizó Google Forms. Resultados: Predominaron las mujeres (73, 50.4 y 70 % en Brasil Paraguay Uruguay); 124 trabajaban en la comunidad y 75 en servicios de urgencias. Los MAP de Brasil y Uruguay reconocieron los síntomas de rinitis alérgica; 67 % de Uruguay no preguntaba sobre antecedentes de diagnóstico de rinitis alérgica, 93 % sobre diagnóstico de asma y 90 % sobre la interferencia de la rinitis con las actividades diarias. Uso de corticosteroides intranasales: 78, 92 y 54 % de los médicos de Brasil Paraguay y Uruguay; 100, 73.4 y 78 % de Paraguay, Brasil y Uruguay no derivaban el paciente al especialista; 26.6, 62 y 6 % de Brasil, Paraguay y Uruguay conocían ARIA. Conclusiones: La rinitis alérgica frecuentemente es atendida por el MAP, pero el reconocimiento de los síntomas y el conocimiento sobre ARIA son reducidos y el tratamiento no siempre es óptimo.
