UC Davis researchers are conducting a first-of-its-kind study to examine genetic and biological markers for disease in women. UC Davis is one of 12 institutions to receive National Heart, Lung and Blood Institute funding to analyze samples taken from more than 160,000 postmenopausal women who participated in the 15-year Women's Health Initiative study. That earlier study focused on strategies for preventing heart disease, breast and colorectal cancer and osteoporosis fractures – the most frequent causes of death and poor quality of life in postmenopausal women. UC Davis was one of 40 sites across the nation that began enrolling women in 1993 for the historic WHI study. More than 4,000 women, ages 50 to 70, from the Sacramento region participated at UC Davis.
