Screening for delayed-onset hearing loss in preschool children who previously passed the newborn hearing screening

Service Delivery to Children With Mild Hearing Loss: Current Practice Patterns and Parent Perceptions

“…Results from the current study and others (Dedhia et al, 2013;Johnson et al, 2005;Lü et al, 2011;Weichbold, Nekahm-Heis, & Welzl-Mueller, 2006) promote the need for continued surveillance of hearing status during childhood. Johnson et al (2005) recommended that children who fail the initial otoacoustic emission screen but pass the subsequent automated ABR should continue to be monitored as part of EHDI high-risk registries if the goal of the NHS program is to identify children with mild HL or worse.…”

“…Numerous studies from developing areas of the world report varying hearing loss prevalence rates among school children. These figures range from 1.4% in China [2] and 1.75% in Saudi Arabia [3], to as high as 11.9% in India [4]. The varying ranges in prevalence is also seen in sub-Saharan Africa with prevalence ranging between 5.6% and 13.9% across studies in rural areas of Kenya [5] and Nigeria [6], respectively.…”

Auditory screening concurrent deafness predisposing genes screening in 10,043 neonates in Gansu province, China

“…Studies conducted in the United Kingdom showed that the prevalence of hearing loss increased from 1.06% at birth to 1.65% at 9 years of age [4]. In Shanghai, Lü et al reported that the prevalence of delayed-onset hearing loss in preschool children who previously passed newborn hearing screening was 0.75% [9]. Therefore, the conventional auditory screening programs have limitations in identify delayed-onset hearing loss and its etiology.…”
