RESUMO
OBJETIVO: Estimar a frequência de história pregressa de chiado, descrevendo as características clínicas e formas de tratamento utilizadas. MÉTODOS: Coorte retrospectiva incluindo lactentes (6-23 meses de vida) com sintomas de infecção de vias aéreas superiores e relato de episódio prévio de chiado. Os dados foram registrados em questionário anteriormente validado. RESULTADOS: Dos 451 avaliados, 164 (36,4%; IC95% = 31,9-41,0) apresentaram história pregressa de chiado, 148 (32,8%; IC95% = 28,5-37,4) no primeiro ano de vida. A média de idade no primeiro episódio de chiado foi de 5,3±3,9 meses. Para quem começou a chiar no primeiro ano de vida, 38,5% referiram entre três e seis episódios e 14,2% > seis episódios. A média da idade no primeiro episódio foi menor para os que apresentaram > três episódios em comparação aos que apresentaram até dois episódios (3,2±2,7 versus 5,7±2,5 meses, p < 0,001). CONCLUSÃO: Um terço dos lactentes apresentou chiado no primeiro ano de vida. Quanto mais cedo ocorre o primeiro episódio, mais frequente é a recorrência do chiado.
OBJECTIVE: To estimate the frequency and describe the clinical characteristics and respective treatments of previous history of wheezing. METHODS: Infants aged 6-23 months with upper respiratory tract complaints and reporting previous wheezing were followed-up retrospectively. Data were registered on a validated standardized form. RESULTS: Out of 451 infants, 164 (36.4%; 95%CI: 31.9-41.0) had a report of prior history of wheezing, 148 (32.8%; 95%CI: 28.5-37.4) during the first year of life. The mean age at the first episode of wheezing was 5.3±3.9 months. Among those who had had their first episode before 12 months of age, 38.5% reported 3 to 6 episodes and 14.2% > 6 episodes. Mean age at first episode was lower for those with > 3 episodes in comparison with those with < 2 episodes (3.2±2.7 vs. 5.7±2.5 months, p < 0.001). CONCLUSION: One third of the infants reported wheezing during the first year of life. The earlier the first episode occurs, the more frequently wheezing recurs.
