Prevalence of rhinitis and associated factors in adolescents and adults: a Global Asthma Network study.

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.

Exposure to indoor air pollution/outdoor air pollution: the silent killers ­ A pilot study / Exposição à poluição do ar interno/poluição do ar externo: os assassinos silenciosos ­ Estudo piloto

Objective: To identify possible risks factors of exposure to indoor air pollution (IAP)/outdoor air pollution (OAP) and their relationship with noncommunicable diseases in men and women treated by primary care physicians. Method: In total, 551 patients (382 women) attended three basic health units in Uruguaiana, Brazil, for various complaints, and completed a questionnaire about risk factors for exposure to IAP/OAP. Results: Women were significantly more exposed to wood-burning pollutants (79.6% vs. 52.7%, p < 0.0001) for having more housework-related activities; men had more outdoor activities and spent extended periods in traffic (47.3% vs. 18.8%, p < 0.0001). Arterial hypertension (AH)/ chronic respiratory disease (CRD) were more frequent among women. Patients with AH/CRD were more exposed to OAP because of their work (18.1% vs. 11%, p = 0.02) or for living near a source of air pollution (45.6% vs. 29.6%, p = 0.0002) or on a street with heavy traffic (41.7% vs. 33%, p = 0.04). Passive smoking, active smoking, using wood, charcoal, or firewood for cooking, heating, or drying, or burning charcoal indoors were not associated with a higher prevalence of AH/CRD. Conclusion: Exposure to OAP was associated with AH/CRD. Women were more exposed to IAP from burning firewood, and men were more exposed to fossil fuel burning. Knowledge of these behaviors should be directed to primary care physicians and all health professionals so that preventive and educational measures can be implemented.

Objetivo: Identificar possíveis fatores de risco da exposição à poluição intradomiciliar (PID) e extradomiciliar (PED) e sua relação com doenças não transmissíveis (DNT) em homens e mulheres tratados por médicos de atenção primária. Método: Quinhentos e cinquenta e um pacientes (382 mulheres) atendidos em três unidades básicas de saúde em Uruguaiana, Brasil, por queixas diversas, responderam a um questionário sobre os fatores de risco para exposição à PID/PED. Resultados: As mulheres foram significantemente mais expostas aos poluentes da queima de lenha (79,6% vs. 52,7%, p < 0,0001) por terem mais atividades domésticas; os homens praticaram mais atividades ao ar livre e passaram longos períodos no trânsito (47,3% vs. 18,8%, p < 0,0001). Hipertensão arterial (HA) / Doença respiratória crônica (DRC) foram mais frequentes entre as mulheres. Pacientes com HA/DRC foram mais expostos à PED devido ao trabalho (18,1% vs. 11%, p = 0,02), ou por viver perto de uma fonte de poluição do ar (45,6% vs. 29,6%, p = 0,0002), ou em uma rua com trânsito intenso (41,7% vs. 33%, p = 0,04). O fumo passivo, o fumo ativo, o uso de lenha ou carvão para cozinhar, aquecer ou secar ou queimar carvão em ambientes fechados não foram associados a maior prevalência de HA/DRC. Conclusão: A exposição à PED foi associada a HA/CRD. As mulheres foram mais expostas à PID pela queima de lenha, e os homens foram mais expostos à queima de combustíveis fósseis. O conhecimento destes comportamentos deve ser direcionado aos médicos da atenção básica e a todos os profissionais da saúde, para que medidas preventivas e educacionais possam ser implementadas.

Prevalence of asthma symptoms and associated factors in adolescents and adults in southern Brazil: A Global Asthma Network Phase I study.

BACKGROUND: The Global Asthma Network (GAN) aims to find out the current status of the prevalence and severity of asthma, rhinitis, and eczema using global surveillance to achieve worldwide recognition and improve the management of asthma, especially in low- and middle-income countries. The aim of this study was to verify the associated factors for asthma in adolescents and their respective parents/caregivers. METHODS: Adolescents (13-14 years old; n = 1058) and their respective parents/caregivers (mean age = 42.1 years, n = 896) living in the town of Uruguaiana, Southern Brazil fulfilled the standardized questionnaire. RESULTS: Although the prevalence of wheezing in the past 12 months was higher among adults than adolescents (18.4% vs. 15.8%, respectively), adolescents showed more severe wheezing and worse control over the disease revealed by higher consumption of short-acting beta-2 agonists; going to the emergency room; hospitalization in the last year and dry night cough. Smoking and paracetamol use were associated with risk for developing asthma symptoms and consuming seafood/fish was protective. For the adults smoking (10 or more cigarettes/day) and exposure to mould in the house were associated with risk for asthma symptoms. CONCLUSIONS: Adolescents have a high prevalence of asthma symptoms and few have an action plan. Adults do not have their disease under control and they use more relief than preventive medication. Differences in associated factors could determine the outcomes in asthma control among adolescents and their parents.

[Primary care physicians' knowledge about allergic rhinitis and its impact on asthma (ARIA guidelines): a comparative Brazilian/Paraguayan/Uruguayan pilot study]. / Conocimiento de médicos de atención primaria sobre Rinitis Alérgica y su Impacto en el Asma (ARIA): estudio piloto comparativo Brasil, Paraguay, Uruguay.

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.

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.
