My main research involves studies of dietary supplementation to prevent chronic diseases and intervention of childhood obesity.
As the Project Director of a USDA-funded multi-center 2-year follow-up, randomized, double blind, and placebo-controlled study, I am working to determine the safety, efficacy, and optimal dosage of soy isoflavones to prevent osteoporosis in postmenopausal women. Four hundred multi-ethnic, healthy, postmenopausal women have been enrolled in the study. One-third of these women received a placebo, one-third received isoflavone supplementation at 80 mg/day; and the remaining one-third received isoflavone supplementation at 120 mg/day. To monitor safety, mammograms, well-woman examinations, Pap smears, stool guaiac tests, and clinical blood chemistries will be performed. To monitor efficacy, total body and regional bone mineral content and density, as well as biochemical bone markers, will be measured. To determine the optimal dosage, changes in bone measurements will be related to blood isoflavone concentrations. Osteoporosis awareness programs including science-based information on the health benefits of soy isoflavones, conducted by the Cooperative Extension Service, will improve the knowledge and skills of consumers enabling them to make informed food choices. I am also the Principal Investigator of an on-going NIH-funded project to determine the potential health benefits of soy isoflavone supplementation to prevent high blood pressure among postmenopausal women. Areas of future focus will include the potential health benefits of botanicals against cardiovascular disease, diabetes, infectious disease, and cancer.
I was the principal investigator of a Texas Department of Health-funded project to determine the prevalence and risk factors of childhood obesity in Texas . The study showed that approximately 36% of the students attending public schools within the Houston Independent School District were overweight, 19% of whom were obese. The percentage of students who were overweight or obese was higher among African Americans and Hispanics than among Caucasians. Areas of future focus will include studies to assess the effectiveness of school-based and community-based programs to prevent excessive weight gains among elementary-school aged children.
