The accuracy of parental suspicion of hearing loss in children.

Parental suspicion of hearing impairment in their children is generally inaccurate. Parents tend to underestimate hearing problems in their children. The aim of the study was to assess the accuracy of parental suspicion of hearing loss in their children. This was a population-based, epidemiological study conducted in elementary schools in villages and small towns in Poland. The study sample was 64,750 children aged 6-13 years old. The children underwent hearing screening with pure-tone audiometry. The parents answered a question about hearing problems in their children. The outcome parameters were sensitivity, specificity, and predictive value of parental perception of hearing problems in their children. Parental suspicion of hearing problems was assessed by a questionnaire. Pure-tone air-conduction hearing thresholds were obtained from 0.5 to 8 kHz. Hearing loss was defined as a pure-tone average higher than 20 dB in one or both ears in at least one of the three following pure-tone averages: four-frequency pure-tone average, high-frequency pure-tone average, and low-frequency pure-tone average. Positive results of hearing screening were obtained in 16.3% of children. Hearing loss was detected in 6025 children (9.3%), of whom 1074 (17.8%) were correctly perceived by parents as having hearing problems. The degree of hearing loss was a significant factor which influenced the sensitivity of parental suspicion of HL in their children. Sensitivity of detecting hearing loss by parents reached about 20% for mild hearing loss and above 31% for moderate or worse hearing loss. Parents underestimate hearing problems in their children, but they are more able to accurately detect hearing loss if it involves speech-related frequencies and is at least a moderate hearing loss or bilateral loss.
