Relationship between Body Mass Index and Knee Osteoarthritis at UKI General Hospital in 2017

Abstract

Knee osteoarthritis is a degenerative joint disease usually suffered by elderly patients, contributing to the high risk of disability. The risk factors that affect the severity of knee osteoarthritis are obesity, age, sex, occupation, patient's history of the disease, trauma, and other factors. Excessive body weight is a factor that exacerbates the disease of osteoarthritis. Generally, this research is aimed to examine the correlation between Body Mass Index (BMI) and knee osteoarthritis at UKI General Hospital. The researcher used a descriptive-analytic study with a cross-sectional approach. In this study, the researcher used 30 samples. The result of chi-square analysis by using Fisher's Exact Test shows that a p-value = 0.045 indicates that the p-value of BMI is under the significance level of α = 0,05. Therefore, the researcher concluded that there is a correlation between BMI and knee osteoarthritis, in which a high BMI value (>24.9) may affect the occurrence of joint space narrowing among the patients. The mean BMI value among the osteoarthritis patients UKI General Hospital is 25.6, which highly indicates that most osteoarthritis patients are preobese/ overweight.
