Knowledge of endometrial cancer risk factors in a general gynecologic population

Abstract

Objectives: To determine knowledge regarding endometrial cancer (EC) risk factors in a general gynecologic patient population.

Study design: A questionnaire survey regarding health behaviors and knowledge of risk factors of EC was administered to patients presenting for routine gynecologic care at two general gynecologic practices affiliated with a tertiary-care center between August and October 2014. Patient demographics, lifestyle information, and knowledge regarding EC risk factors were assessed. Data were analyzed using univariable and bivariable analyses, Χ² tests, Fischer's exact tests, and t-tests.

Results: 231 women responded. Median age was 56 years old (IQR 25-64), and 87% were Caucasian. Median BMI was 24.9 (IQR 22.3-29.2). 24.7% were overweight and 24.3% obese. The majority (69.4%) of patients received a college or graduate degree. Over half of the women (52.1%) did not know that obesity was associated with increased risk of EC. When dichotomized based on obese vs non obese, there was no difference in patients' knowledge of the association between obesity and EC (47% vs 48%, respectively, p = .93). 91% of all respondents reported that their gynecologist or primary care physician had never discussed the risks of EC with them.

Conclusions: Regardless of education level, age or obesity status, the majority of women did not know the common risks of EC. Increased efforts towards educating women regarding obesity and other risk factors of EC are necessary in order to reduce the rising incidence of EC, a predominantly obesity-driven disease. Interventions must include general obstetrician-gynecologists and primary care providers.
