Evaluation of the use of a questionnaire to detect hearing loss in Kenyan pre-school children

Questionário para monitoramento do desenvolvimento auditivo e de linguagem no primeiro ano de vida

“…As observed in Tables 2 and 3, when the sensorineural hearing loss is considered, the applied questionnaire demonstrated specificity of 96% and sensitivity of 67% -data consistent with the previous studies that used the questionnaire as methodology (21)(22)(23)(24) . It is important to highlight that the sensitivity of the tool and the false negative index obtained (33%) were the result of the non-identification of the two children with unilateral sensorineural hearing loss.…”

“…The use of questionnaires as a way of identifying alterations in the auditory development in different age groups is widely discussed in the literature (21)(22)(23)(24) .…”

“…Generally, the studies pointed out that questionnaires directed to the identification of alterations in the hearing function present specificities between 94% and 100% and sensitivity varying from 10% to 75% (21)(22)(23)(24) . This variability in sensitivity can be justified by the methodological differences in regard to the age group studied, comprised of children between 6 months and 7 years of age; or with regard to the value of audibility considered as hearing loss, which in some studies had been considered 40 thresholds above the dB HL definition of incapacitating loss of the WHO (16) or above 20 dB HL when considering children of 0 to 1 year (28) .…”

“…In the first year of life the family's suspicion of mild alterations is extremely uncommon due to the fact that speech and language development in these cases can be similar to that of children with normal hearing (22) .…”

Childhood Disability in Low- and Middle-Income Countries: Overview of Screening, Prevention, Services, Legislation, and Epidemiology

“…Study populations of children were identified either through population-based sampling [12][13][14][15][16][17][18][19][20][21][22][23][24][25] or schools. [26][27][28][29][30][31][32][33] Some studies focused on the parents of children with disabilities and tried to assess their needs and attitudes with respect to disability. [34][35][36] Among the others, 3 studies [37][38][39] were clinic based, with a primary focus on the epidemiology and available services for cerebral palsy.…”
