Measurement of handgrip strength on dynamometer could be a simple way to help identify patients at risk of developing type 2 diabetes, researchers have said after measuring the muscular handgrip strength of 776 men and women without a history of diabetes over a 20-year period.
The study is published in the journal Annals of Medicine.
In the 779 study subjects, the risk of type 2 diabetes was reduced by around 50 per cent for every unit increase in handgrip strength value, said scientists at the universities of Bristol and Eastern Finland in a paper published in the journal Annals of Medicine. Reduced muscular strength, which can be measured by handgrip strength, has consistently been linked to early death, cardiovascular disease and disability.
Until recently, there was inconsistent evidence on the relationship between handgrip strength and type 2 diabetes. In a recent literature review of 10 published studies on the topic, the same researchers demonstrated that people with higher values of handgrip strength had a 27 per cent reduced risk of developing diabetes.
However, while findings from this review suggested handgrip strength could potentially be used to predict type 2 diabetes, researchers needed to test this formally using individual patient data.
In the latest study, the researchers from Bristol Medical School and Eastern Finland’s Institute of Public Health and Clinical Nutrition followed 776 men and women aged 60-72 years without a history of diabetes over a 20-year period and measured the power of their hand grip strength using a handgrip dynamometer.
Patients were asked to squeeze the handles of the dynamometer with their dominant hand with maximum isometric effort and maintain this for five seconds.
The results demonstrated that the risk of type 2 diabetes was reduced by about 50 per cent for every unit increase in handgrip strength value.
