BACKGROUND AND OBJECTIVES: Uterine fibroids (UFs) are the most common neoplasm affecting reproductive-age women. The purpose of the present study is to explore the association between dietary diversity and risk of UFs in a cross-sectional study of urban premenopausal women.
METHODS AND STUDY DESIGN: A total of 248 urban premenopausal women with age of 20-45 were recruited in 3 randomly chosen hospitals in Shijiazhuang, China. Dietary diversity was assessed from food frequency intake data using dietary diversity score (DDS), Prime Diet Quality Score (PDQS) and food variety score (FVS). UFs were diagnosed by the methods of ultrasound, pelvic exam, or surgery. Binary logistic regression was used to estimate the relationship between dietary diversity and risk of UFs.
RESULTS: 37 of the study subjects (14.9%) had UFs. Participants with a low education level and single marital status participants had a lower DDS and PDQS, respectively. After adjustment for confounding factors, a higher DDS 24 was associated with decreased UF risk (OR=0.22, 95% CI=0.05-1.01). Similar trends were observed for the plantbased FVS (ptrend=0.025). Carrot (OR=0.04, 95% CI=0.00-0.48) and kiwi fruit (OR=0.03, 95% CI=0.00-0.47) were also inversely associated with risk of UFs after adjustment for confounding factors.
CONCLUSIONS: Multifarious food groups and the increase of variety of plant-based food, especially carrot and kiwi fruit, may be associated with the lower risk of UFs; they may play an important role in inhibiting the formation of UFs.
