My statistical methods research, in conjunction with colleagues and students aims to improve the design and analysis of disease prevention trials, and observational studies. Recent efforts have brought attention to the profound role that measurement error in assessing individual dietary intakes may play in reducing the reliability of observational studies of food and nutrient consumption and the risk of cancer and other chronic diseases. As a result an innovative research agenda has been advocated thatincludes a major emphasis on international comparisons of dietary habits and cancer incidence rates, the addition of objective biomarkers of nutrient intake to the conduct of cohort and case-control studies, and a major emphasis on dietary intervention development for subsequent testing in controlled intervention trials. Another emphasis has been the development of flexible methods for the analysis of multivariate failure time data. These methods are motivated by the challenges of assessing benefits versus risks in the context of disease prevention trials having multiple clinical outcomes that may be affected by a preventive intervention, and by emerging issues in the identification of cancer related genes and gene-environment interactions.
My applied research, in conjunction with a large group of colleagues and staff members, include coordination of the national Women's Health Initiative. This massive 15 year program randomized over 68,135 postmenopausal women into a clinical trial to evaluate therole of a low-fat eating pattern for the prevention of breast cancer, colorectal cancer and coronary heart disease; to evaluate the role of hormone replacement therapy for the prevention of coronary heart disease and fractures, with breast cancer as a potential adverse outcome; and to evaluate the role of calcium and vitamin D supplementation for the prevention of fractures and colorectal cancer. An additional 93,720 women have been enrolled in an observational study to identify risk factors for this same range of diseases. We operate the clinical coordinating center for this NIH-sponsored program, with clinical, nutritional, epidemiologic, statistical and data management coordination responsibilities. We expect to report the principal findings from the Women's Health Initiative Clinical Trial in 2005-2007.
