Relationship of Body Mass Index to Waist Circumference, Blood Pressure, Random Blood Sugar, and Uric Acid: Case Study in Elderly Health Community

This study investigated the relationship between Body Mass Index (BMI) and waist circumference, blood pressure, random blood sugar, and uric acid levels at the Elderly Association. A cross-sectional design was employed, involving 31 participants with an average age of 66.81 ± 2.83 years, selected through purposive sampling. Using Spearman’s Rho correlation and multiple regression analysis, the study found a moderate positive correlation between BMI and waist circumference (r = 0.653), blood pressure (r = 0.618), and uric acid levels (r = 0.731). This suggests that higher BMI is associated with increased levels of these indicators. Regression analysis further supported these findings, demonstrating a significant effect of BMI on waist circumference (B = 0.400, p = 0.006), blood pressure (B = 0.274, p = 0.008), and uric acid levels (B = 0.490, p = 0.002). While a correlation existed between BMI and random blood sugar (r = 0.538, p = 0.002), BMI did not significantly influence random blood sugar levels (B = 0.068, p = 0.630). Therefore, the study concludes that managing BMI could potentially reduce health risks in the elderly, particularly concerning waist circumference, blood pressure, and uric acid levels.
