Introduction: Endometrial cancer is one of the most common cancers among women of highly developed countries. Purpose: The purpose of the study was to evaluate the selected reproductive factors increasing or decreasing the odds ratio (OR) of endometrial cancer in women. Material and Methods: The study involved 400 women aged 40 to 84 years of Obstetrics and Gynecology University Hospital in Poznań. It evaluated parameters such as age, anthropometric data (body weight, height). In addition, number of births and miscarriages, age of the first and last menstruation, the age at which the first child was born, duration of breastfeeding, use of hormonal contraception, and co-morbidities were analyzed. Results: Women menstruating over the age of 55 years are characterized with nearly eight-fold increased risk of endometrial cancer (OR = 8.8, 95% Cl 1.348-57.428). The OR of developing the cancer in women giving the first birth between 20 and 25 years of age is OR= 0.297; 95% Cl 0.307-0.969, and in women between 26 and 30 years of age OR = 0.218; 95% Cl 0.073-0.650 when compared to women giving birth to their first child below 20 years of age. Conclusions: Women menstruating over 55 years of age and using hormonal contraception have an increased risk of developing endometrial cancer.
