PREVENTION RESEARCH CENTER NOTES
"Promoting Health Through Physical Activity"

Welcome to the May/June 2000 issue of the PRC Notes! The first official day of summer is this week – be sure to take necessary precautions for outdoor activity in hot and sunny weather. Drink plenty of water and protect yourself from the sun – slip on a tee shirt, slap on a hat and slop on some sunscreen. Be careful and have a great summer!

NEWS YOU CAN USE

KICKING YOUR WAY TO FITNESS: The latest fitness craze, cardio-kickboxing, will allow you to burn an average of 350 to 450 calories per hour and reach a heart rate of 75% to 85% of your maximum heart rate, which is within the recommended range of 65% to 85% for aerobic exercise. This activity is offered at many health clubs and recreation centers nationwide. Make sure your instructor is certified and that you learn a few basic moves before participating. Don’t forget to warm-up, stretch, and cool down to avoid injuries. For more information see http://content.health.msn.com/content/article/1676.50657. This site has links to other related sites. 

RESEARCH NOTES

COMMUNITY WALKING TRAILS: Residents of 12 rural Missouri counties were surveyed about their physical activity behaviors, knowledge and attitudes and their attitudes towards and use of community walking trails. Just over one third of respondents said they had access to walking trails, and almost 40% of those had used the trails. Of those who used the trails, 55.2% said they walked more often since they began using the trails. Women and individuals with a high school education or less were more than twice as likely to have increased their amount of walking. The authors concluded that “Walking trails may be beneficial in promoting physical activity among segments of the population at highest risk of inactivity, in particular women and persons in lower socio-economic groups.” See Brownson, Housemann, Brown, Jackson-Thompson, King, Malone & Sallis, “Promoting physical activity in rural communities: Walking trail access, use and effects.” American Journal of Preventive Medicine, April 2000, 18(3):235-241. 

TRACKING RURAL ADOLESCENT PHYSICAL ACTIVITY BEHAVIORS: Researchers measured physical activity and health related physical fitness variables of fifth graders in South Carolina. Two hundred sixty-nine rural, predominantly African-American students provided baseline data and 181 of these participated in sixth and seventh grade follow-up assessments. A Previous Day Physical Activity Recall (PDPAR) self-report instrument was used to list the main activities in which students participated during after school hours (3PM to 11:30PM). Health related physical fitness measures (cardiorespiratory endurance, upper body strength, and body composition) were also collected. The study suggested that specific sedentary behaviors tracked well over time, but tracked poorly in combination. There was a tendency for students to maintain physical activity status. Measures of health related physical fitness had a moderate to strong tracking tendency. A significant percentage of students classified as “at risk” for low levels of physical activity and health related physical fitness remained “at risk” two years later in the seventh grade. The authors suggest that public health initiatives should begin early and target children and adolescents to promote lifelong physical fitness before unhealthy behavior patterns are fully established. See Pate, Trost, Dowda, Ott, Ward, Saunders & Felton, “Tracking Physical Activity, Physical Inactivity, and Health-Related Physical Fitness in Rural Youth.” Pediatric Exercise Science, 1999, 11:364-376. 

PREVALENCE OF LEISURE TIME PHYSICAL ACTIVITY AMONG OVERWEIGHT ADULTS: The leisure-time physical activity (LTPA) patterns of overweight adults (Body mass index of > 25.0) were reported in a recent MMWR. The report is based on the 1998 Behavioral Risk Factor Surveillance System (BRFSS) national data set. In 1998, 66.6% of overweight men and 62.2% of overweight women reported trying to lose weight by using LTPA. The prevalence of using LTPA to lose weight was lowest among residents of southern states. In 1998, 62.7% of overweight adults used LTPA as a strategy for weight loss by participating in at least 30 minutes per session and 28.0% participated in LTPA five or more times per week. Both sexes reported walking as the most frequent activity (37.7% for men and 52.5% for women). Two-thirds of overweight adults reported using LTPA as a method of weight reduction. However, although most reported exercising for > 30 minutes per session, a minority exercised at least five times per week. Another finding was that LTPA as a method for weight reduction was least common among obese, least educated, and older persons. See “Prevalence of Leisure-Time Physical Activity Among Overweight Adults – United States, 1998.” Morbidity and Mortality Weekly Report, April 21, 2000, 49(15):326-330. 

DETERMINANTS OF ADOLESCENT PHYSICAL ACTIVITY: The National Longitudinal Study of Adolescent Health was analyzed to examine determinants of physical activity and inactivity among adolescents grades 7 – 12. Activity and inactivity were both divided into three levels: low, medium, and high. Researchers found that having physical education 1 to 4 times a week was associated with a 44% increase in the likelihood of falling into the highest level of physical activity. Having physical education 5 times a week was associated with a 121% increase in falling into the highest level of physical activity. Using a recreation center was associated with a 75% increase in the likelihood of falling into the highest level of physical activity, and high crime levels in the neighborhood were associated with a 23% decrease in the likelihood of falling into the highest level of physical activity. Other socio-demographic variables were examined as well. The researchers note that the data may be misleading because it is possible that community recreation centers may not have been available to some respondents, and it is also possible that physically active people are more likely to use recreation centers. [Ed.: It is also possible that physically active youth are more likely to take additional physical education classes beyond the minimum required for high school graduation.] However, as one of a very few studies which have examined these issues, this research points the way toward future research. See Gordon-Larsen, McMurray & Popkin, “Determinants of Adolescent Physical Activity and Inactivity Patterns.” Pediatrics Online, June 6, 2000, 105(6):e83 [www.pediatrics.org/cgi/content/full/105/6/e83]

REPORTS, SURVEYS, GUIDELINES, RESOURCES

YOUTH RISK BEHAVIOR SURVEILLANCE (YRBS): The 1999 YRBS summary was released in the June 9, 2000 issue of CDC’s Morbidity and Mortality Weekly Report (Vol. 49, No. SS-5). The summary is available online at http://www.cdc.gov/mmwr/, and is also available by contacting 202-512-1800. Information related to physical activity includes participation in vigorous and moderate physical activity, strengthening exercises, television watching, physical education class, and sports teams. State-level statistics are provided where available. 

SCHOOL HEALTH INDEX: To help provide structure and direction to school efforts to improve health promotion policies and programs, CDC has produced the “School Health Index: A Self-Assessment and Planning Guide” for physical activity and healthy eating. Future guides will focus on other healthy behaviors. Available in an elementary school version or a middle/high school version, the School Health Index enables schools to 1) Identify strengths and weaknesses of school policies and programs, 2) Develop an action plan for improving student health, and 3) Involve teachers, parents, students and the community in improving school services. A brochure about the index is available as well. The index can be downloaded at http://www.cdc.gov/nccdphp/dash/SHI/index.htm. It is available to schools at no cost, by calling 1-770-488-3168, e-mailing ccdinfo@cdc.gov, or faxing 1-888-282-7621. When ordering, specify either the elementary or middle/high school versions. [From the School Health Index brochure.]

“SISTERS TOGETHER” PROGRAM: The National Institute of Diabetes & Digestive & Kidney Disease (NIDDK) of the National Institutes of Health (NIH) has published the Sisters Together Program Guide. The guide is based on the 3-year “Sisters Together: Move More, Eat Better” program designed to encourage African American women in Boston to control their weight by increasing physical activity and eating healthy foods using culturally appropriate classes, demonstrations, and seminars. The Sisters Together planning guide and walking brochure can be accessed at http://www.niddk.nih.gov/health/hutrit/sisters/sisters.htm, or call WIN’s toll-free number (800) WIN-8098.
