Age-related changes in hand grip strength among rural and urban Haryanvi Jat females

The aim of this study was to investigate the age-related changes in hand grip strength (both right and left hand) among rural and urban Jat females and its correlation with various anthropometric variables. The present cross-sectional study was based on a sample of 600 Jat females (rural=300, urban=300), ranging in age from 40 to 70 years. Findings indicated that rural and urban Jat females exhibit an age-related decline in the mean values of hand grip strength (both right and left hand). The comparison suggested that rural Jat females had significantly higher overall mean value of hand grip strength (kg) (right hand=20.35 vs 18.87, p<0.001 and left hand=17.05 vs 15.68, p<0.001) than their urban counterparts. Mean values for right hand grip strength were found to be higher than left hand grip strength in rural as well as urban Jat females. Significant and positive correlation coefficients exist between hand grip strength (both right and left hand) and various anthropometric variables (height, weight, body mass index, biceps and triceps skinfold thickness) in both rural and urban Jat females. An age-related decline in manual functioning of rural and urban Jat females may be attributed to behavioral factors (reduced physical activity, sedentary lifestyle) and poor nutrition (deteriorating quality and quantity of food intake with increasing age) associated with the normal aging process.
