(HealthDay News) — A higher intake of sugar and sugar-sweetened beverages is associated with a higher risk of some endometrial cancers, according to a study published online Nov. 22 in Cancer Epidemiology, Biomarkers & Prevention.

Maki Inoue-Choi, Ph.D., R.D., from the University of Minnesota in Minneapolis, and colleagues analyzed data from 23,039 postmenopausal women who reported their demographics, anthropometry, medical and family history, lifestyle, and dietary intake (via a food frequency questionnaire) in 1986.

By 2010, the researchers identified 506 type I and 89 type II incident endometrial cancers. After adjusting for various factors, including body mass index, higher intake of sugar-sweetened beverages was associated with an increased risk of type I cancers (hazard ratio, 1.78 for highest quintile of intake compared with no intake). Higher sugar intake was also associated with a higher risk of type I cancers. In contrast, there was no association between diet and the risk of type II cancers.
