[Body mass index and triponderal index in abnormal uterine bleed].

Background: Abnormal uterine bleeding (AUB) is the most common cause of blood loss. Obesity and overweight are risk factors for AUB.
Objective: To compare the association between body mass index (BMI) and tri-ponderal mass index (TMI) with the presence of acute AUB and chronic AUB.
Material and Methods: Observational, cross-sectional and analytical study. Women between 18 and 45 years of age with an alteration in the regular uterine bleeding pattern were included. Postmenopausal women, carriers of an intrauterine device as a method of family planning who have developed alterations in the menstrual rhythm after it, those who suffered from chronic diseases (chronic kidney disease, diabetes mellitus and uncontrolled hypothyroidism) and those with medication consumption that alter coagulation were not included. Pregnant patients were excluded.
Results: A total of 292 women with AUB were analyzed, with a median age of 38.5 (IQR 33-41), with bleeding of 205.4 mL (±142.9) and 116 (39.86%) of them with overweight. When analyzing the BMI with SUA, we found no significant difference in the presence of acute or chronic bleeding in the overweight (p = 0.46) and obese (p = 0.41) groups. When analyzing the IMT with the presence of acute or chronic AUB, it was not possible to find a significant difference in the overweight (p = 0.98) and obesity (p = 0.93) groups.
Conclusions: The BMI was compared with the TMI for the presence of AUB, without finding a significant association.
