UNIVERSITY OF SOUTH CAROLINA
PREVENTION RESEARCH CENTER NOTES
"Promoting Health Through Physical Activity"

Happy Valentine’s Day – A goal for our monthly newsletters is to share information about physical activity from a public health perspective. A public health problem is one that affects the health, function, and well being of a large number of people. According to national data, nearly 60% of US adults do not get enough activity to prevent chronic diseases and disabilities and another 25% are sedentary. These data call for action that addresses community environments and policies to promote active lifestyles. What is happening in your community that promotes activity? What else could be happening? Share your ideas and activities with us and we will pass them on to others in future issues of the Prevention Research Center Notes. We hope you enjoy our newsletter this month.

NEWS YOU CAN USE

WINTER WORKOUTS -- DRESS FOR SUCCESS: There are 2 key strategies to working out in the cold: layer and protect your vulnerable parts. Layering should be done to insulate a pocket of warm air around the body, and each layer has a purpose. The inner layer should keep perspiration from getting you cold. The better choices are thermal underwear made from synthetic fibers or wool. Cotton is a poor choice. The middle layer’s purpose is to provide warmth without the bulk. Synthetic or wool sweaters, and fleece jackets are recommended middle layers. The outer layer should repel wind and precipitation while allowing perspiration and heat to escape. A nylon parka and pants are recommended. To avoid overheating, dress so that you are a little chilled when you first walk outside. The body’s extremities suffer the most from the cold because they are normally exposed, and the body naturally shuttles more heat inward to protect the vital organs. For the feet, invest in a pair of shoes with less ventilation and better traction. Also buy them a little big to make room for an extra pair of socks. To protect the hands, try wearing thin synthetic glove liners and put cotton gardening gloves over them. For the head and face, wear a cap. Over 40% of the body’s heat loss is through the scalp. When exercising in the cold, be aware of body sensations to avoid possible frostbite or hypothermia. If these are suspected, seek shelter immediately and warm the body up. (From the January 1999 edition of Consumer Reports on Health)

ACTIVE PLAY: Based on their recent research (published in the Melpomene Journal, Vol 17, No. 2, Summer, 1998), Melpomene Institute has developed a brochure describing the difference in how girls and boys play. Girls typically are less vigorously active than boys, play less structured games and are often unsure of the rules when wanting to join in the organized boys' games. The brochure provides tips for parents and adult supervisors to encourage active play. Up to 10 brochures "Playgrounds: Encouraging active play for girls and boys" are available to educators for FREE. Brochures are $1.50 each or 100 for $45. Call (651) 642-1951 or e-mail <melpomen@skypoint.org>. The research article can be downloaded from <www.melpomene.org>.

WHAT’S HAPPENING IN WASHINGTON

BUDGET TROUBLES AHEAD: President Clinton has stated he will request a $12 billion increase in military spending for FY 2000 and $110 billion over a six-year period. In meetings with House Budget Committee staff, public health groups were told a significant portion of the military spending increase will come at the expense of domestic discretionary programs including public health. Public health groups are bracing for a difficult budget cycle this year. (From the Council of State and Territorial Epidemiologists "Washington Report.")

RESEARCH NOTES

LIFESTYLE VS. STRUCTURED INTERVENTIONS: Researchers studied 235 sedentary men and women for two years to compare the effects of a lifestyle physical activity program with traditional structured exercise on improving physical activity, cardiorespiratory fitness and CVD risk factors. Both the lifestyle and structured activity groups had comparable and significant improvements in physical activity, in systolic and diastolic blood pressure. Neither group significantly changed their weight but each group significantly reduced their percentage of body fat. See Dunn et al. "Comparison of Lifestyle and Structured Interventions to Increase Physical Activity and Cardiorespiratory Fitness." Journal of the American Medical Association, 1999; 281:327-334.

LIFESTYLE VS. STRUCTURED ACTIVITY IN OBESE WOMEN: In order to examine short and long term weight loss and cardiovascular disease risk factors, researchers conducted a sixteen-week trial with a one year follow-up. Forty obese women participated in either structured aerobic exercise or moderate lifestyle activity; all ate a low-fat, low-calorie diet. There was no significant difference between the groups in terms of weight loss. The lifestyle activity group lost less fat. After one year, the lifestyle group had regained less weight. See Anderson et al. "Effects of Lifestyle Activity vs. Structured Aerobic Exercise in Obese Women." Journal of the American Medical Association, 1999;281:335-340.

DAILY PE AND ITS EFFECTS ON ADULT PHYSICAL ACTIVITY: A study in Quebec, Canada investigated whether a daily primary school physical education program influenced physical activity levels, attitudes towards physical activity, and perceptions to barriers of physical activity later in life. The study had an experimental group of 147 men and women who had received five days per week of physical education classes during their six years of primary school and a control group of 720 that were sociodemographically matched to the experimental group. Women in the experimental group participated in more physical activity as compared with women in the control group, and men in the experimental group had a lower frequency of smoking when compared to the control group. No effect was seen between the experimental and control groups on intention to exercise, attitudes towards exercise, or perceiving opportunities to exercise. See Trudeau et al. "Daily primary school physical education: effects on physical activity during adult life." Medicine & Science in Sports & Exercise, 31(1):111-117, 1999.

DOES PHYSICAL ACTIVITY TRACK INTO ADULTHOOD?: Researchers analyzed various components of physical activity during childhood and teenage years and compared them with exercise habits in adulthood. 105 men completed a questionnaire about their current exercise habits and their physical activity habits while growing up. The study found that men who enjoyed physical activity and had good athletic skill during childhood and teenage years were more likely to be active as adults. However, being forced to be physically active during childhood and the teenage years and being encouraged to exercise during the childhood years was related to less participation in physical activity as adults. See Taylor et al. "Childhood and adolescent physical activity patterns and adult physical activity." Medicine & Science in Sports & Exercise, 31 (1): 118-123, 1999.

PHYSICAL ACTIVITY AND FITNESS: A cross-sectional examination of physical activity patterns associated with low, moderate and high levels of cardiovascular fitness was conducted in 13,444 men and 3972 women age 20 to 87 years, who had at least one comprehensive examination at the Cooper Aerobics Center in Dallas, Texas. Average energy expenditures of 525 to 1650 kcal per week for men and 420 to 1260 per week for women were associated with moderate to high levels of fitness. These levels of energy expenditure can be achieved by taking a brisk walk of 30 minutes most days of the week. Stofan et al. "Physical Activity Patterns Associated with Cardiorespiratory Fitness and Reduced Mortality: the Aerobics Center Longitudinal Study." American Journal of Public Health, December 1998; 88:1807-1813.

IN-HOME EXERCISE FOR DISABLED OLDER ADULTS: A randomized controlled trial of 215 older persons with disabilities found that a home-based resistance exercise program was successful in increasing strength and reducing disability. The Strong-fo-Life Program incorporated cognitive and behavioral strategies, which the researchers say led to 89 percent adherence over six months. See Jette et al. "Exercise – It’s Never Too Late: the Strong for Life Program." American Journal of Public Health, January 1999;89:66-72.
