Abstract
Background: Hand grip strength (HGS) is a key indicator of upper limb strength and daily functioning. Body mass index (BMI) is commonly used to assess physical health, but its relationship with muscle strength is not well defined.
Objective: This study aimed to examine the association between BMI and HGS in the dominant and non-dominant hands among undergraduate medical students in Lahore.
Methods: A cross-sectional study was conducted with 129 participants from Akhtar Saeed Medical College. HGS was measured using a hand-held dynamometer, and BMI was calculated from measured height and weight. Data analysis was performed using SPSS version 23, and the Chi-square test was used to assess associations between BMI categories and HGS.
Results: The majority of participants were right-hand dominant (96.9%). The association between BMI and HGS was found to be insignificant for both the dominant (p = 0.10) and non-dominant hands (p = 0.995).
Conclusion: The study concluded that BMI does not have a significant impact on HGS in either hand, suggesting that BMI may not be a reliable predictor of muscle strength in this population.
