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.
