Background: Hearing impairment (HI) is an important disability hampering the overall development, particularly cognitive domain in children. Coexistence of HI with intellectual disability (ID) affects adversely the overall prognosis of a child. To highlight this underdetermined issue, this study has been done to determine the proportion of ID in children of HI. Materials and Methods: This cross-sectional study is held in children with HI of 0–42 months. In the study subjects, psychological assessment was done by Baily Scale of Infant Development III (BSID III). Detailed history was taken; physical examination was done in each patient after taking informed written consent. Hearing assessment was done by an audiologist and was leveled as mild, moderate, severe, and profound. Results: The study subject was 203, and mean age was 27.2 ± 8.7 (3–42) months. There was a slight male predominance. Majority of children mode of birth was lower uterine segment cesarean section. Neonatal seizure was significantly associated with intellectual impairment in the study subject (P <0.001). No significant association of the HI was found in different levels of intellectual status of the children; however, 35% of the study subject had borderline intellectual status and most of them belonged to the profound HI. Conclusion: A significant proportion of the study subjects had borderline intellectual status, although very limited numbers had ID. Moreover, children with profound hearing loss were most affected.
