The Association Between Body Mass Index, Waist to Hip Ratio and Mid-Upper Arm Circumference with Endometriosis

Abstract

Endometriosis is characterized by the presence of endometrial tissue outside the uterus in the form of glands and stroma. Increased fat distribution is one of the risk factors for endometriosis. This study aimed to determine the relationship between body mass index (BMI) and endometriosis because BMI only measures overall body mass and not fat tissue mass. The study performed anthropometric tests, including waist-to-hip circumference ratio (WHR) and mid-upper arm circumference (MUAC). This study was analytical observational research with a case con-trol. Between October 2018 and October 2020, 63 patients diagnosed with endo-metriosis through laparoscopic action and 63 normal women with no symptoms of endometriosis and no abnormalities on ultrasound evaluation of the reproductive organs met both inclusion and exclusion criteria. The measurement result of BMI in kg/m² is categorized into ≤25 and >25, WHR is categorized as <0.85 and ≥0.85, and MUAC in centimetres to ≤23.0 and >23.0. The result showed the relationship of BMI, WHR, and MUAC with endometriosis incidence obtained BMI with endometriosis (b=0.824, CI 95%=0.99 to 5.25, p=0.053), WHR (b=0.893, CI 95%=1.03 to 5.82, p=0.044), and MUAC (b=-0.246, CI 95%=0.10 to 6.09, p=0.814). BMI and WHR are associated with an increased risk of endometriosis.
