Objectives: The most important aspect of hearing loss is its effect on the communication abilities of individuals. The aim of this study was to compare the prevalence of attention deficit hyperactivity disorder (ADHD) in hearing-impaired (HI) children with normal-hearing (NH) peers.
Methods: A total of 130 children (65 children with severe-to-profound hearing loss and 65 NH peers) participated in this cross-sectional study from November 2013 to May 2014. ADHD Rating Scale IV questionnaires were given to children's parents to collect data. Descriptive and analytical analyses were used in order to achieve the objectives of the study.
Results: The mean age of the HI children and NH peers was 14.1 and 13.3 years, respectively. In the case group, 52 children suffered from congenital hearing loss and 10 children had acquired hearing loss. In total, 19 cases (29.2%) and eight controls (12.3%) were diagnosed with ADHD. This difference was statistically significant (P=0.017). The prevalence of ADHD in children with hereditary or acquired hearing loss was 30.7% and 20.0%, respectively. However, this difference was not significant (P=0.71).
Conclusion: The prevalence of ADHD in school-aged children with hearing loss is higher than that in the general population of the same age. We could not find significant differences between the different subgroups due to the small sample size. Therefore, we recommend a further larger study to determine the interaction between hearing loss and ADHD.
