Karthik Devaraju, Smrithi C Shetty.


Background: Type 2 diabetes a non-communicable disease with high prevalence rate globally as well as in India is known to cause mental and physical slowing and psychological stress which usually goes unnoticed in the initial stages.

Aims and Objectives: This study aims to assess and compare the cognition functions, muscle strength, and perceived stress in diabetics and normal controls.

Materials and Methods: Fifty-two type 2 diabetes patients and 52 age- and sex-matched controls were randomly selected for the study after the approval from the institutional ethics committee. Stress levels were recorded by perceived stress scale questionnaire, cognitive function test using Mini–Mental State Examination (MMSE), and handgrip strength of the dominant and non-dominant hand was determined using a Handgrip Dynamometer. Student’s t-test was used to compare the various parameters among diabetics and normal controls and Pearson correlation coefficient was used to correlate all the parameters.

Results: Diabetics had higher perceived stress score and lower MMSE than nondiabetics. Handgrip strength in diabetics was slightly reduced than non-diabetic group and was higher in males compared to females diabetic males and females with more than 10 years duration had significantly higher score for perceived stress and poor MMSE (

Key words: Cognition; Diabetes; Handgrip Strength; Perceived Stress
