New Strategic Plan for NIH Obesity Research Seeks To Combat Epidemic

To address the obesity epidemic, the National Institutes of Health (NIH) is encouraging diverse scientific investigations through a new Strategic Plan for NIH Obesity Research.

More than one-third of U.S. adults and nearly 17 percent of U.S. children are considered obese, a condition that increases risk of type 2 diabetes, heart disease, stroke, and high blood pressure. In addition to its health costs, obesity imposes a financial burden. (In 2008 alone, obesity-related medical costs were about $147 billion.)

The Strategic Plan for NIH Obesity Research highlights the crucial role of research in reducing obesity. Developed by the NIH Obesity Research Task Force, the plan stresses moving science from the laboratory to clinical trials to practical solutions.

The NIH has long been investing in research related to obesity and its health risks. In 2010, the NIH provided $824 million in research funds, plus awards totaling $147 million made through the Recovery Act. The strategic plan will guide NIH investments in research, interventions, and outreach to understand and reduce the prevalence of obesity. “This plan is a bold blueprint that will encourage the research community to examine the prevalence of obesity from diverse perspectives,” said NIH Director Francis Collins, M.D., Ph.D.

The plan includes the following overarching themes:

  • Discover key processes that regulate body weight and influence behavior.
  • Understand the factors that contribute to obesity and its consequences.
  • Design and test new approaches for achieving and maintaining a healthy weight.
  • Evaluate promising strategies for obesity prevention and treatment in real-world settings and diverse populations.
  • Use technology to advance obesity research and improve health care delivery.

The NIH Obesity Research Task Force is co-chaired by Griffin P. Rodgers, M.D., director of the National Institute of Diabetes and Digestive and Kidney Diseases; Susan B. Shurin, M.D., acting director of the National Heart, Lung, and Blood Institute; and Alan E. Guttmacher, M.D., director of the Eunice Kennedy Shriver National Institute of Child Health and Human Development. These three Institutes led the plan’s development together with the National Cancer Institute.

The task force aims to accelerate progress in obesity research across the NIH. Since the release of the first strategic plan in 2004, research produced the following findings:

  • Lifestyle interventions for weight loss reduce risk for heart disease and type 2 diabetes. NIH-funded studies are testing ways to bring these proven strategies to more people.
  • Recent NIH-funded research is identifying new targets and pathways for prevention and treatment of obesity, through novel technologies such as brain imaging studies.
  • When a woman with obesity or diabetes becomes pregnant, her child’s chances of developing obesity or diabetes may increase, suggesting a critical period to intervene. Researchers can study approaches to help woman achieve a healthy weight before and during pregnancy.

Study Finds Lifestyle Intervention Improves Risk Factors in Type 2 Diabetes

An intensive lifestyle intervention created to help participants lose weight and keep it off improves diabetes control, as well as heart disease and stroke risks, in overweight and obese individuals with type 2 diabetes. These improvements are shown in the four-year results of the Look AHEAD (Action for Health in Diabetes) study funded by the NIH and the Centers for Disease Control and Prevention. The results are published in the September 27, 2010, issue of the Archives of Internal Medicine.

This multi-center, randomized clinical trial is unique in that it examines intervention effects over the long term. Researchers from 16 centers across the United States randomly assigned a total of 5,145 participants to an intensive lifestyle intervention or a diabetes support and education program (DSE).

At the time of enrollment, participants were between 45 and 76 years of age, and their mean body mass index (BMI) was 36. (BMI is a measurement of weight in relation to height.) Thirty-seven percent of participants were from racial and ethnic minority groups, and approximately 60 percent were women. About 94 percent of participants remain involved after 4 years and will continue to be followed for up to 13.5 years.

Participants in the ongoing intensive lifestyle intervention attend individual and group meetings and regularly communicate with a lifestyle counselor. Working with this lifestyle counselor, participants learn behavioral skills, such as problem-solving and goal-setting. Participants set specific diet and exercise goals and are encouraged to track their progress through a diet and exercise diary.

In comparison, the DSE group is invited to three group sessions each year focused on diet, physical activity, or social support, but they are not weighed or counseled on behavioral strategies.

When compared across the 4 years, participants in the intervention group, on average, lost more weight (6.2 percent of initial body weight, compared with only 0.9 percent in the DSE group). The intervention group also experienced greater increases in good cholesterol, greater improvement in blood pressure and treadmill fitness, and better control of blood sugar. This is an ongoing study, so continued follow-up will determine whether these improvements are sustained and whether the lifestyle intervention leads to less cardiovascular disease and death. Full results will not be available for several years.

Weight Wise Program Helps Low-Income Women Lose Weight

Findings published in a 2009 issue of the journal Obesity indicate that the Weight Wise Program (WWP), a lifestyle intervention for low-income women who are considered overweight or obese, promoted an average weight loss of nearly 15 pounds.

The NIH and the Centers for Disease Control and Prevention provided support for the 5-month randomized controlled trial, in which a total of 143 women participated. The participants were uninsured and underinsured women with low family income who were considered overweight or obese at the beginning of the study. About 60 percent of participants were non-Hispanic Whites, and 38 percent were non-Hispanic Blacks.

Researchers randomly assigned 71 women to an untreated control group that received two newsletters on unrelated health topics (skin health and back pain) and 72 women to the 16-week WWP lifestyle intervention. Conducted at a community health center and a nearby church, WWP included weekly group education sessions adapted for cultural appropriateness (materials written at a lower reading level and including low-cost healthy meals that reflect local preferences). Participants kept a daily diet and exercise record and provided personal feedback reports summarizing their weight loss progress.

On average, participants in this short-term study lost 14.8 pounds, which is similar to weight loss results typically achieved by interventions conducted with higher-income populations. Average attendance was 10 out of 16 sessions, and participants who attended more sessions lost more weight. Several factors promoted increased attendance, including offering the sessions four times during the week, providing incentives for attendance and participation, and holding the meetings at a local church rather than a clinic.

In addition to weight loss, researchers found measured improvements in blood pressure and good cholesterol, as well as self-reported improvements in diet and physical activity.

Combining Aerobic and Resistance Training Improves Blood Sugar Control in Individuals with Type 2 Diabetes

Results from the Health Benefits of Aerobic and Resistance Training (HART-D) trial show that a combination of aerobic exercise and resistance training improves control of blood sugar more than either type of training alone. Study findings are published in a 2010 issue of the Journal of the American Medical Association.

At the beginning of the NIH-funded trial, participants had an average body mass index (BMI) of 35 (BMI is a measurement of weight in relation to height, with 30 or higher considered obese). Researchers used a standard test of blood sugar control, hemoglobin A1c (HbA1c), to measure the effects of three exercise programs and a control program. At the beginning of the trial, the average HbA1c level of participants was 7.7 percent, which is considered elevated.

The researchers randomly assigned participants (165 women and 97 men) to one of four groups:

  • Aerobic Exercise Group—about 140 minutes per week on the treadmill (across 3 sessions)
  • Resistance Training Group—about 140 minutes per week lifting weights (3 sessions)
  • Combination Training Group—about 110 minutes on the treadmill (3 sessions) and 30 to 40 minutes lifting weights (2 sessions)
  • Control Group—stretching and relaxation classes

Because interim analysis by the Data Safety Monitoring Board indicated that HbA1c was increasing more in the control group than in the active treatment groups, researchers stopped recruiting participants into the control group. This led to unequal numbers of participants across groups (41 control, 72 aerobic, 73 resistance, 76 combination).

The combination training group experienced a statistically significant decrease in HbA1c levels compared with the control group. Although HbA1c levels also decreased in the other two training groups, the differences were not significantly different from the control group. All three training groups experienced significant improvements in waist size, but the combination training group experienced the greatest decrease: an average of 1.1 inches.

Report Finds Need To Improve U.S. Physical Education Programs

In their 2010 Shape of the Nation Report, the National Association for Sport and Physical Education (NASPE) and the American Heart Association (AHA) find that while more States are requiring physical education in schools since the previous report (2006), many State mandates include "loopholes" that weaken physical education requirements.

Physical education programs vary widely from State to State because no Federal law mandates physical education for K–12 students. Since 1987, NASPE has been monitoring this variation by writing and releasing its Shape of the Nation Report. To gather data about the 2009–2010 school year, NASPE and AHA sent online questionnaires to the Physical Education Coordinator in each of the 50 States and the District of Columbia.

The authors found notable increases in the percentages of States requiring physical education:

  • 84 percent now require physical education in elementary school, compared with 70 percent in 2006
  • 76 percent in middle school, compared with 65 percent in 2006
  • 90 percent in high school, compared with 83 percent in 2006

According to NASPE and AHA, however, these State mandates are diluted by substantial increases in the number of States that allow students to substitute other activities for physical education credit or to apply for waivers that excuse them from requirements.

The authors recommend that all States develop statewide physical education standards that reflect NASPE's national standards. They encourage school officials, parents, and communities to work together to encourage students to participate in physical activity beyond the physical education classroom: Students should have opportunities to participate in sports, walk/bike-to-school programs, and other active clubs. And finally, neighborhoods and communities should have well-paved roads, sidewalks, parks, and other recreation areas that the public can use to promote physical activity.

Federal Government Releases Updated Dietary Guidelines

HHS and the U.S. Department of Agriculture have released the Dietary Guidelines for Americans, 2010, containing Government recommendations on improving health and reducing chronic diseases and obesity through healthy eating and increased physical activity.

Based on an analysis of scientific research, the Dietary Guidelines provide 23 recommendations for the general public and six for specific groups (such as pregnant women) to encourage Americans to adopt three healthful habits:

  • Balancing calorie intake across the lifespan by eating sensible portions, increasing physical activity, and decreasing inactive behaviors
  • Building a healthy eating pattern that emphasizes nutrient-packed foods and beverages, including vegetables, fruits, whole grains, fat-free or low-fat milk and milk products, seafood, lean meats and poultry, eggs, beans and peas, and nuts and seeds
  • Limiting intake of added sugars, solid fats, trans fats, sodium, and refined grains

Recognizing the social and economic factors that affect diet, including food security that affects nearly 15 percent of U.S. families unable to obtain the food they need, the Dietary Guidelines close with a "Call to Action" section to improve public health for all Americans. Among other efforts, this section suggests actions such as creating strategic plans to help communities address the Dietary Guidelines, expanding access to grocery stores, ensuring equal access to healthy foods and physical activity, and developing sustainable agricultural practices.

CDC Estimates That Diabetes Affects 25.8 Million Americans

The prevalence of diabetes increased from 7.8 percent of the population in 2008 to 8.3 percent of the population in 2010, according to the National Diabetes Fact Sheet, 2011, released by the Centers for Disease Control and Prevention (CDC). The CDC notes that the 2010 numbers may not be directly comparable to 2008 data because this is the first year in which prevalence calculations included the hemoglobin A1c blood level as a diagnostic test for diabetes. However, the number of Americans estimated to have diabetes continues to rapidly increase and these new prevalence estimates come shortly after 2010 CDC projections that suggest diabetes prevalence may reach at least 21 percent by 2050.

The CDC estimates that nearly 26 million Americans have diabetes, and 7 million of these individuals do not know they have the disease. An additional 79 million adults have pre-diabetes, which increases their risk of type 2 diabetes, heart disease, and stroke.

Several factors contribute to the increasing prevalence of diabetes:

  • More people are developing diabetes (approximately 1.9 million newly diagnosed cases in 2010).
  • The U.S. population is aging, and the risk of diabetes increases with age (half of Americans ages 65 and older have pre-diabetes; nearly 27 percent have diabetes).
  • People with diabetes are living longer, which means the number of new diagnoses is not balanced with the number of people with diabetes who die each year.

The increasing prevalence of diabetes not only affects the long-term health of the United States population but costs $174 billion annually, including $116 billion in direct medical costs and $58 billion in indirect costs, such as disability and loss of work.

Federal Government Helps Consumers Track Health on the Go

The U.S. Government has joined the move to track health on the go with its USA.gov Mobile Apps page (http://apps.usa.gov).

By providing mobile apps (short for "applications"), the U.S. Government becomes part of an expanding field known as Mobile Health, or mHealth, which involves using mobile technology for various health purposes. Mobile calorie trackers, phone-based pedometers, and Bluetooth-enabled glucose trackers are only a few of the tools now available formonitoring one's health while on the go.

Included on the USA.gov Mobile Apps page are two apps that focus on healthy eating and weight control:

  • My Food-a-Pedia is a free mobile app from the U.S. Department of Agriculture (USDA). This app allows consumers to search for information on more than 1,000 foods. For each item, the app provides the number of calories, how the food fits into the USDA's five food groups, and the number of calories from solid fats, added sugars, and alcohol (http://apps.usa.gov/myfood-a-pedia.shtml).
  • BMI Calculator, a popular tool on the National Heart, Lung, and Blood Institute's website, is now available as a free iPhone app. Consumers can enter their height and weight to determine their body mass index (BMI), a useful tool for those losing weight as they monitor their progress toward a healthy BMI (http://apps.usa.gov/bmi-app.shtml ).

NIDDK Posts Nutrition Obesity Research Centers Annual Report 2009–2010

In November 2010, NIDDK completed the Nutrition Obesity Research Centers Annual Report 2009–2010. This document combines individual reports from 12 scientific centers funded by the NIH through the NIDDK to research the development, treatment, and prevention of obesity and the role of diet in disease prevention.

The funded centers unite basic science and clinical investigators from many institutions and disciplines—such as biochemistry, molecular biology, genetics, and physiology—and many medical specialties—such as internal medicine, pediatrics, and surgery. Because of the interdisciplinary nature of the centers' activities, success in achieving goals depends on close interactions among obesity and nutritional science researchers, health services providers, and educators. The Annual Report demonstrates how these close interactions among investigators and health professionals at the various centers have resulted in significant advances in the fields of obesity and nutritional science.

The center reports, available on the NIDDK website, highlight scientific and educational accomplishments; pilot and feasibility studies; and research, publications, and further funding developed from original NIDDK-supported activities.

WIN Encourages You To Start a Sisters Together Program

People around the country are helping their communities move more and eat better by starting Sisters Together programs that target Black women ages 18 and older. Esther Sharpe and colleagues at the Women’s Health Ministry of the Universal End Time Harvest in Greenville, SC, kicked off their Sisters Together program by hosting a Women’s Health Conference in November 2010. You can do the same for your community. Consider organizing a Sisters Together program in your area. The following activities from current programs may help you get started:

Sisters on the Move Towards Better Health is organized by Dr. Sandra Holmes, Vice President of the KYANNA Black Nurses Association of Louisville, KY. An early activity of this program was a health fair with demonstrations on cooking nutritious foods, line dancing, exercise sessions, massage, and tai chi. A health fair or expo is a great way to begin spreading your message. Holmes’s program has also included a walking group, recipe-testing events, and participation in community events with other organizations. For example, Sisters on the Move Towards Better Health collaborated with Grass Roots for Community Empowerment to host healthy cooking demonstrations called “Tasty Tuesdays.”

Sisters Together activities at North Carolina Agricultural and Technical State University are organized by Dr. Patricia Lynch, Assistant Professor of Food & Nutrition. Her program has included monthly meetings on fitness and healthy eating on campuses and in churches, healthy cooking demonstrations and a Sisters Together cookbook, and events in honor of national health observances. Many of these activities are quick-and-easy ways to launch your program.
