OBJECTIVE: To determine the prevalence of @entity2346 media with effusion in @entity1 younger than 1 year and its association with the season of the year, artificial feeding, environmental and perinatal factors. METHODS: Retrospective study of 184 randomly included medical records from a total of 982 healthy @entity1 evaluated for hearing screening tests. @entity2346 media with effusion was based on otoscopy (amber-gold color, fluid level, handle of @entity2113 ), type B tympanometric curves and absence of otoacoustic emissions. Incomplete medical records or those describing @entity697 , @entity1729 on the assessment day or in the last 3 months, @entity16 and @entity2122 were excluded. Data such as gestational age, birth weight, Apgar score, type of feeding and day care attendance were compared between @entity1 with and without @entity2346 media with effusion through likelihood tests and multivariate analysis. RESULTS: 25.3% of 184 @entity1 had @entity2346 media with bilateral effusion; 9.2% had unilateral. In @entity1 with @entity2346 media, the following were observed: chronological age of 9.6  1.7 months; gestational age >38 weeks in 43.4% and birth weight >2,500g in 48.4%. @entity2172 with effusion was associated with winter/fall, artificial feeding, Apgar score <7 and day care attendance. The multivariate analysis showed that artificial feeding is the factor most often associated to @entity2346 media with effusion. CONCLUSIONS: @entity2172 with effusion was found in about one third of @entity1 younger than 1 year and was mainly associated with artificial feeding.
