Exploring the role of uterine fibroids in promotion of cardiovascular diseases by diabetes exposure: Findings from national health and nutrition examination survey 1999–2006

ObjectiveThe relationship between uterine fibroids (UF) and cardiovascular diseases (CVDs) in the diabetes population seemed to remain undetermined in previous studies. This study aims to explore the association between UF and CVDs by using the database from the National Health and Nutrition Examination Survey (NHANES). To further evaluate the connection between UF and CVDs we also tested the potential differences due to diabetes exposure.Materials and methodsNational Health and Nutrition Examination Survey data (1999–2006) were collected and used in this study. A total of 5,509 individuals were included and analyzed. The student’s t-test and the chi-squared test were used to explore the demographic characteristic between UF and non-UF groups. Logistic regression analysis was performed to determine the odds ratios of UF and covariates.ResultsFemale participants were divided into UF (n = 694, 12.60%) and non-UF (n = 4,815, 87.40%) groups. The incidence of CVDs in UF patients (n = 245, 35.30%) were higher than non-UF individuals (n = 776, 16.12%) (p < 0.001). In addition, each subtype of CVDs were also different, which contains hypertension (33.29 vs. 15.31%, p < 0.001), heart failure (1.59 vs. 0.52%, p < 0.01), angina (2.59 vs. 0.62%, p < 0.001), heart attack (1.73 vs. 0.58%, p < 0.01) and coronary heart disease (1.44 vs. 0.54%, p < 0.01). The odds ratios of CVDs according to logistic regression were 2.840 (95% CI: 2.387–3.379) for UF patients (p < 0.001), while the odds ratios (ORs) were 1.438 (95% CI: 1.175–1.760) after taking account for the age, body mass index (BMI), diabetes, race, education, and annual family income (p < 0.001). In addition, secondary analysis indicated more adverse effects in by UF exposure on CVDs risk among non-diabetes individuals (OR = 1.389, 95% CI = 1.124–1.718, p < 0.01) than diabetes patients (p = 0.063).ConclusionOverall, UFs were positively associated with CVDs, and this effect seems blunted by diabetes exposure.
