Abstract :

Background: Anemia is common problem in adolescent girls in many developing countries including India. Low hemoglobin levels may lead to decreased attentiveness and low neuronal metabolic action.

Objectives: To observe and compare the effects of hemoglobin level on auditory and visual reaction time in Non– Anemic and anemic girls of same age group.

Material and Methods: Adolescent girls of age group 17–19 years were included in the study. Hemoglobin estimation was done using Sahali�s Hemoglobinometer. Two groups were made. Group I (n= 40) with estimated haemoglobin concentration ≥12 gm%. Group II (n=40) with estimated haemoglobin concentration<12gm%. Auditory and visual reaction time have been measured using Reaction time analyzer. Recorded observations were analysed using Epi–info software.

Results: Significant difference (p<0.05) in auditory and visual reaction time was found between two groups. Conclusion: Both auditory and visual reaction time were found to be delayed in Group II having hemoglobin<12gm% as compared to those having hemoglobin ≥ 12gm%. Sensorimotor performance is affected in anemic individuals.
