Reducing Nationwide Obesity Starts in Neighborhoods
Hearts Ní Parks Program Brings Science, Skills to 50 Communities

Children, adolescents, and adults reported adopting healthier behaviors — such as choosing heart-healthy foods more often — after participating in a Hearts N' Parks program, according to a new report on the community-based lifestyle initiative. In addition, adults said they boosted their level of regular physical activity after the program. Hearts N' Parks was developed in 1999 by the National Heart, Lung, and Blood Institute (NHLBI) and the National Recreation and Park Association (NRPA) to reduce the growing trend of obesity and the risk of coronary heart disease in the United States.

The new report, available on the NRPA Web site, summarizes the results of written questionnaires administered by Hearts N' Parks program staff to more than 1200 children, adolescents, and adults on their knowledge, behavior, and attitudes regarding heart-healthy eating and physical activity before and after participating in a program in 2002. Overall, participants improved in nearly every indicator.

"High blood pressure, high blood cholesterol, diabetes, heart disease, and stroke — these are just a few of the health problems that obesity and overweight contribute to," said Dr. Claude Lenfant, director of NHLBI, a component of the National Institutes of Health. "Hearts N' Parks is all about bringing what research has shown about the health risks associated with overweight and obesity to the community — and empowering people to make better lifestyle choices in order to improve their overall health."

Hearts N' Parks incorporates science-based information about lifestyle choices that can reduce the risk of coronary heart disease and skills for adopting heart-healthy behaviors into regular activities offered by park and recreation departments and other community-based agencies. The program focuses on encouraging Americans of all ages to aim for a healthy weight, follow a heart-healthy eating plan, and engage in regular physical activity. Training for recreational staff and tools for measuring the impact of their activities is provided.

More than 50 Hearts N' Parks sites ("magnet centers") are now active in 11 states: Arizona, Florida, Georgia, Illinois, Indiana, Maryland, Michigan, Missouri, Nevada, New Mexico, and Ohio. Many magnet centers are holding special "FunFit" events in July — including several that are tied to local Fourth of July celebrations. For example, 40,000 people are expected at a July 4 event in Athens, GA, where there will be a special Hearts N' Parks tent with games, prizes, and health and wellness information. On July 5, residents of Roswell, NM, can measure their body fat and learn how to grill low-fat foods in conjunction with the city's annual Alien Chase. Over 100,000 people are expected at a July 6 concert and fireworks event in South Bend, IN that will feature Hearts N' Parks displays, nutrition and fitness quizzes. A July 11 Fun Fit Festival Field Day in Las Vegas, NV will be held for children in summer day camps who will participate in field games, swimming, and a healthy lunch contest.

"We want to reinforce the idea that celebrating good health is as important as celebrating democracy — and that individuals and families can have fun doing both," commented John Thorner, CAE, executive director of NRPA. July events also commemorate Recreation and Parks Month, an annual public awareness initiative of NRPA. "This year's theme, 'Community Sports and Health,' ties in nicely with the goals of Hearts N' Parks programs," added Thorner.

The Hearts N' Parks model supports the Department of Health and Human Services' Steps to a Healthier US initiative, based on the President's Healthier US Initiative. These initiatives highlight the influence that healthy lifestyles and behaviors have in achieving and maintaining good health for individuals of all ages. They also encourage public-private partnerships to support community-driven programs on healthy lifestyles that contribute directly to the prevention or treatment of one of three key health problems: obesity, diabetes, or asthma.

The new report, "Hearts N' Parks - Phase II: Report of 2002 Magnet Center Performance Data," includes information on 68 programs which varied in size and duration. Data was collected by 36 Hearts N' Parks sites during their first year as a magnet center. Programs for children or adolescents were typically provided during summer camps or as after-school activities for 7 to 11 weeks. Adult programs, which lasted an average of 12 weeks, attracted largely seniors and women.

"Combining proven health interventions and skills training with local recreational facilities seemed like a natural," added Karen Donato, S.M., R.D., coordinator of the NHLBI Obesity Education Initiative. "Now we have the information to show that it really works."

Highlights of the performance report include:

  • Children's scores improved significantly in all areas: heart-healthy eating knowledge (8 percent increase in correct answers), behavior (14 percent increase), and intention (19 percent increase).

  • Children's scores in physical activity attitude increased; they reported that they "learned" or "would like to play again" an average of five activities while they "got better at "approximately seven activities.

  • Adolescents' scores improved significantly in heart-healthy eating behavior (20 percent increase), intention (15 percent increase), and in overweight/obesity knowledge (7 percent increase).

  • Adult participants significantly improved their scores in all areas of knowledge, attitude, and behavior studied. They increased their knowledge of heart-healthy nutrition with a 9 percent increase in correct answers. Scores increased by 6 percent to 7 percent in knowledge of overweight/obesity risks, physical activity, causes of high blood pressure, and ways to control cholesterol levels. Post-test scores also suggest healthier attitudes toward overweight/obesity, heart-healthy eating habits, and physical activity, and improvements in how frequently participants chose healthy foods, based on self-reports.

  • Adult participants reported adding, on average, 2 hours of moderate physical activity per week (from 8 hours to 10 hours), such as bicycling, walking and golfing, after participating in Hearts N' Parks. In addition, they reduced the time spent in sedentary activities by an average of 8 hours per week, down to 33 hours.

  • Post-test scores of participants over 60 years old showed greater improvement overall than younger adults. Seniors' pretest knowledge scores were lower than younger adults' scores, but post-test knowledge scores were comparable. Seniors also significantly increased time spent weekly in physical activity on average from slightly fewer than 6 hours to more than 8.5 hours, and significantly lowered the amount of time each week in sedentary tasks by 10 hours, down to 20 hours.
