CHRONIC SUPPURATIVE OTITIS-MEDIA WITHOUT CHOLESTEATOMA IN CHILDREN IN SOUTHERN ISRAEL - INCIDENCE AND RISK-FACTORS

The incidence and risk factors for chronic suppurative otitis media without cholesteatoma in children in Southern Israel were determined by comparing 88 children with the disease to 76 controls with similar age distribution who visited 3 clinics serving representative populations of the region. Data were collected during the child's visit to the clinic by means of a structured interview with the parents and by extracting information from medical records. The calculated yearly incidence was 39/100 000 children 0 to 15 years of age. Significantly increased risk for chronic suppurative otitis media was associated with a history of acute and recurrent otitis media, a parental history of chronic otitis media, larger families and more siblings, a higher crowding index and care in large day-care centers. The sex, parental age and education, allergy, sinusitis and recurrent upper respiratory tract infections were not associated with chronic suppurative otitis media.
