Background: Hand muscle strength is the most accurate examination for assessing hand function. Hand muscle strength describes the working capacity of the hand muscles for physical activities that utilize the hand. The magnitude of handgrip strength can be influenced by several factors such as hormones, age, physical exercise, and nutritional status, especially BMI. This study aims to determine the correlation between BMI and right hand grip strength in female students of the Medical Education Study Program, Class of 2023, University of Lampung.
Method: This research used an observational analytic study with a Cross-Sectional design. The study sample were female students of the Medical Education Study Program, Class of 2023, University of Lampung. The sampling method used was total sampling, involving 142 people, with a minimum required sample of 64 people. The independent variable was BMI and the dependent variable was hand muscle grip strength. The Spearman correlation test was used to analyze the relationship between the two.
Results: The average handgrip strength of the female students was 23.4 kg, and the average BMI was 18.68 based on the 126 samples obtained. The majority of respondents had a normal level of handgrip strength (76.2%) and their BMI was in the normal category (61.6%). The Spearman statistical test yielded a correlation coefficient (r) of 0.187 and a significance (p) value of 0.037.
Discussion: The (p) value of 0.037 indicates a significant relationship, with r = 0.187 suggesting a positive but weak correlation between BMI and handgrip strength. This finding indicates that the higher the BMI, the stronger the hand muscle grip. This relationship is not always strong because BMI cannot differentiate between muscle mass and fat mass.
Conclusion: There is a significant correlation between Body Mass Index (BMI) and hand muscle grip strength in Female Students of the Medical Education Study Program, Class of 2023, University of Lampung.
