Abstract
The current study aimed at identifying the relationship between the blood group and
hearing thresholds. The objective of the study was to identify if there is a difference
in the pure tone audiometric thresholds of individuals with different blood groups,
and to identify if there is a difference between pure tone audiometric thresholds
of males and females of the same blood group. A prospective study was performed involving
80 normal hearing individuals between the age of 18 and 40 years. All participants
included in the study had normal hearing (< 25 dBHL) and were Rh+. Participants complaining
or giving indications of any kind of cochlear or retrocochlear pathological conditions
were excluded from the study. Participants were grouped based on their blood groups.
Each group consisted of 20 participants. Thresholds were established for frequencies
ranging from 125 Hz to 20 KHz. Descriptive statistical analysis was done for mean
and standard deviation. Bonferroni post hoc analysis was carried out for multiple
comparisons, and the results revealed that there was no statistically significant
difference in thresholds observed among different blood groups.
