Introduction: The incidence of malignant tumors of the uterine body is increasing in the Czech Republic. Endometrial adenocarcinoma is one of the most frequent morphological types. Obesity or even overweight is a risk factor for the development of this disease. More accurate stratification of risk relative to body mass index (BMI) has not yet been determined in the Czech Republic, although the risk of overweight (BMI 25–29.9) has been reported in one study as comparable to that of first or second degree obesity (BMI 30–30.9). Patients and methods: The study population included 376 women of Caucasian race diagnosed with endometrial adenocarcinoma, with BMI measured simultaneously, in 2005–2017. A control group consisted of an equal number of age-matched women not diagnosed with any oncological or gynecological disease. These two files were statistically processed. Results: Odds (OR, 95% CI) relative to normal weight women, overweight women were at 2.26-times higher odds of endometrial adenocarcinoma, and women with obesity were at 5.18-8.67-, and 24.70-times higher odds, depending on the severity of obesity. Conclusion: The hypothesis that overweight represents same risk for the development of endometrial adenocarcinoma, as lower degrees of obesity was not verified. However overweight is serious risk for endometrial adenocarcinoma development. The odds of endometrial adenocarcinoma is correlated with increasing BMI and in the population studied is higher than reported previously for all endometrial carcinoma subtypes.
