Review Meta AnalysisVitamin D and calcium intake in relation to risk of endometrial cancer: a systematic review of the literature.
In response to a recent ecologic study of UV exposure and endometrial cancer incidence, we present the epidemiologic evidence on the relation between intake of vitamin D and its metabolically related nutrient, calcium, and the occurrence of endometrial cancer. ⋯ The limited epidemiological evidence suggests no relation between endometrial cancer in the ranges of dietary vitamin D examined, and suggests a possible inverse association for calcium from supplements. Prospective studies, ideally including plasma 25(OH) D to estimate vitamin D input from diet and sun exposure, are needed to further explore these hypotheses.

Research evidence addressing effectiveness of tobacco use prevention interventions has accumulated since the 1970s. Systematic reviews 1985-2006 were considered, building on previous syntheses and spanning tobacco control and prevention efforts to date. Practitioners' experience was drawn upon to supplement research evidence. ⋯ There is strong evidence that school-based tobacco use prevention programs are largely effective for most tobacco use related outcomes, at least in the short term.
