[Hearing in children of the Central Federal Region]
Abstract:
A cohort trial of hypoacusis was made in three districts of the Central Federal Region for three years. 11.6% of all hypoacusis and deafness were children under 14 years of age: under 1 year -- 6.3%, 1-3 years -- 9.4%, 4-7 years -- 39.8%, 8-14 years -- 44.4%. Hearing problems were detected in 4% of children under 1 year. In 1-3-year-olds hypoacusis was detected in 13.3%, in 4-7-year-olds -- in 43.2%, in 8-14-year-olds -- in 39.5%. It was established that only in 33.6% junior children hearing defects were related to ENT pathology. 30.4% of hearing lesions in children arise due to pathological pregnancy and labor, 12.5% -- after infectious diseases.
