Presented from NCCU
Broadcast Link: Seminar
In this seminar, Dr. Mitchell will be sharing information on the problem of obesity in the US and suggest reasons for the epidemic, including portion sizes, decreased physical activity and medications. She will also provide scientific evidence and data analysis behind the many national weight loss programs. The obesity epidemic in the US continues and many providers feel that they do not have the time or training to effectively counsel or treat patients for successful weight loss. Dr. Mitchell will focus on reasons for excess weight and obesity in women. She will define “obesity” and describe some of the reasons why it occurs in women with a discussion of health, medications (including birth control and anti-depressants), food, and differences in weight gain for men and women. Comparing calorie intake with exercise, such as pizza and raking leaves, Dr. Mitchell will provide practical examples when looking at the data and facts about weight gain from the National Academy of Medicine. She will also explain Body Mass Index (BMI) as it relates to African American women and associations between BMI and various health problems. Dr. Mitchell will present evidence from data collections and analysis of the effectiveness of popular national weight-loss programs. Using evidence from randomized control trials (RCTs) and analysis of cohort studies, she will present comparative data on 3 popular programs: Weight Watchers, Jenny Craig, and TOPS Club, Inc. (a non-profit organization). What are the retention rates and what happens after one leaves such a program? Weight loss programs, as Dr. Mitchell will explain, can make a difference with weight-related health problems, even when one loses only 5%. She will describe an appropriate weight loss program for obese patients using current evidence.
Dr. Nia Schwann Mitchell. MD, MPH is an Assistant Professor of Medicine in the Division of General Medicine, Dept. of Medicine, at the School of Medicine at Duke University. Dr. Mitchell studied at the Washington University School of medicine, completing her M.D. in 2005. She received her Masters of Public Health (MPH) from the University of Colorado in 2010, and also did her internal medicine residency (2005-2008) and a primary care research fellowship (2008-2010) there. She is completing work on a National Institutes of Health (NIH) grant about the Evaluation of Low Cost National Weight Loss Programs in Underserved Populations. Among articles on weight loss, she recently has co-authored articles on “Factors Associated with the Achievement of Clinically Significant Weight Loss by Women in a National Nonprofit Weight Loss Program” (Journal of Women’s Health, August, 2017) and “Time to RE-AIM: Why Community Weight Loss Programs Should be Included in Academic Obesity Research” (Preventing Chronic Disease, March, 2016). As an Internal Medicine Doctor and a Primary Care Doctor, she sees patients at the Duke Diet and Fitness Center and Duke Outpatient Clinic. Dr. Mitchell and her weight loss research has also been featured on MSN’s “30 Best Ways to Lose Weight after 30.”
The Informatics Research Seminar Series is sponsored by Duke University and a collaboration with UNC-Chapel Hill, NCCU, UNC-Charlotte, and ECU. This series explores key areas in Health Informatics and include research results, overview of programs of research, basic, applied, and evaluative projects, as well as research from varied epistemological stances.
