Evaluation of handgrip strength as an indicator of nutritional status in laborers

Abstract

Background: The laborers constitute an important workforce in the society. Their working efficiency very much depends on their muscle strength. Hand grip strength (HGS) determines the muscular strength of an individual. Nutritional deficiency can affect the muscle strength in laborers. The current study was carried out to assess whether HGS can be useful as an indicator of nutritional status. Aims and Objectives: To assess the relationship between handgrip strength and nutritional status in laborers and to compare it with sedentary counterparts. Materials and Methods: This crosssectional study included 60 laborers and 60 age-matched sedentary counterparts (controls). HGS was measured with hand grip dynamometer. Anthropometric parameters were recorded by standard methods. Data obtained were tabulated and statistically analyzed. Results: HGS and anthropometric parameters were significantly lower in laborers compared to controls. Moreover, all the variables of nutrition, the mean height, weight, body mass index, mid-upper arm circumference, arm muscle girth and arm muscle area in laborers, and sedentary counterparts showed significant positive correlation with the handgrip strength in laborers except for triceps skinfold thickness. Conclusion: The study concluded that there exists a significant correlation between nutritional status and handgrip strength. Efforts should be taken to educate the workers on fundamentals of nutrition emphasizing role of good nutrition in improving work capacity.
