Research Strategies for Nutritional and Physical Activity Epidemiology and Cancer Prevention

Colon Cancer: Nutritional Strategies for Prevention

M any of us have known, or will know, someone who suffers with colon cancer. In its Facts and Figures for 2000, the American Cancer Society estimates that there were 93,800 new cases of colon cancer in the United States in 2000 and 47,700 deaths from the cancer. Commonly recognized risk factors for colon cancer include obesity and low consumption of vegetables, fish, and whole-grain cereals.1 A...

Physical activity and cancer prevention: from observational to intervention research.

The purpose of this review is to articulate how progress in epidemiological research on physical activity and cancer prevention can be made. This report briefly reviews the accumulated evidence for an etiological role of physical activity in the prevention of cancer of the colon, breast, prostate, testes, lung, endometrium, and ovary and summarizes the evidence for a causal association for each...

Molecular epidemiology of physical activity and cancer.

As in other areas of epidemiology, researchers studying physical activity and cancer have begun to include laboratory analyses of biological specimens in their studies. The incorporation of these "biomarkers" into epidemiology has been termed molecular epidemiology and is an approach primarily developed to study chemical carcinogens. Thus far, there has been no discussion in the field on how th...

Antibiotic resistance: epidemiology and strategies for prevention.

Physical activity and breast cancer prevention.

Breast cancer is the most commonly diagnosed invasive malignancy and the second leading cause of cancer death in women. This chapter considers epidemiologic evidence regarding the association between physical activity and breast cancer risk from 73 studies conducted around the world. Across these studies there was a 25% average risk reduction amongst physically active women as compared to the l...
