Integrating the 2008 Physical Activity Guidelines for Americans and the Guide to Community Preventive Services into Adventure Programs Judy Kruger, PhD U.S. Centers for Disease Control and Prevention Division of Nutrition and Physical Activity Physical Activity and Health Branch 5th Annual Research and Evaluation of Adventure Programming (REAP) March 20, 2009 Atlanta, GA
Objectives • Why evidence-base? • Discuss evidence from 2008 Guidelines • Identify evidence from the Community Guide • Identify potential strategies to include in adventure programs
Why evidence-base? • Based on what we KNOW…rather than what we THINK works • Process of planning, implementing and evaluating programs • Individual & community • gain skills/adopt behaviors • improve physical environment
What is evidence = proof? • Evidence of a health effect • Evidence of a program effect • Evidence of program design & context SOME action needed SPECIFIC program effect SPECIFIC delivery effect
Advantages Lead to efficient use of resources Continuity & growth of the program Common performance measures Supports quality improvement Helps establish partnership Disadvantages Need to know where to find evidence Added expense as tools and process are unfamiliar Program appears standardized instead of tailored May impact community buy-in Perceptions
Common components • Specific target population • Specific, measurable goals • Proven benefits • Defined program (structure, timeframe, reasoning) • Support (staffing skills, facility, equipment)
Summary • Evidence-based concepts includes: planning, implementing and evaluating • Many advantages and disadvantages • Multiple evidence-based components to consider

Overview of the 2008 Physical Activity Guidelines for Americans
Scientifically established benefits of physical activity (PA) • ↓ risk of dying prematurely • ↓ risk of dying from heart disease • ↓ risk of developing diabetes • ↓ risk of developing high blood pressure • Helps ↓ blood pressure in people who already have high blood pressure • ↓ risk of developing colon cancer • ↓ feelings of depression and anxiety • Helps control weight • Helps build and maintain healthy bones, muscles, and joints • Promotes psychological well-being
2008 Physical Activity Guidelines for Americans • First major review of the science on benefits of physical activity in over a decade • Complement previous recommendations • Information and guidance on the types and amount of physical activity that provide substantial health benefits
2005 Dietary Guidelines 2008 Physical Activity Guidelines www.health.gov/DietaryGuidelines www.health.gov/paguidelines
3 Phases & Products • Evidence review (managed by CDC) • Database • Advisory committee report (expert panel) • Federal Advisory Report • Writing process (appointed panel) • 2008 Physical Activity Guidelines for Americans
CDC triaged 14,472 abstracts CDC reviewed 1,598 papers FACA developed 650 page report HHS writing group created 65 page document 2008 Guidelines strategy Phase I Phase II Phase III
Phase I Evidence Review • Literature review examined original research published since January 1995 • Health outcome chapters: • All-cause mortality, cardio-respiratory, musculoskeletal, functional health, cancer, mental health, adverse events, metabolic, & energy balance • Stratified by age groups • Children and youth (6-18 years) • Adults (19-64 years) • Older adults (65 + years)
Initial research questions Is physical activity (PA) associated with the health outcome of interest [x]? What dose of PA is associated with [x]? What level of PA intensity influences [x]? Do different modes (types) influence [x]?
Phase II Advisory Committee Report • Utilized literature database to develop consensus on PA & health literature • Health outcome chapters: • All-cause mortality, cardio-respiratory, musculoskeletal, functional health, cancer, mental health, adverse events, metabolic, & energy balance • Additional chapters on understudied populations • Persons with disabilities • Women during pregnancy and the postpartum period • Adults with selected chronic conditions
Phase II Advisory Committee William L. Haskell, Stanford University - ChairMiriam Nelson, Tufts University - Vice ChairRod K. Dishman, University of GeorgiaEdward T.

Powell, Atlanta GeorgiaRussell R. Pate, University of South CarolinaJudy Regensteiner, University of ColoradoJames Rimmer, University of Illinois, ChicagoAntronette Yancey, UCLA
Phase II Advisory Committee Reviewed existing scientific literature to identify sufficient evidence to develop a comprehensive set of specific physical activity recommendations
Phase III Writing Process • Strong reliance upon Advisory Committee Report • Final product - 8 chapters • Fact sheet, toolkits, PowerPoint presentation
Children and Adolescents (ages 6-17) • 1 hour (60 minutes) or more of Aerobic physical activity that is at least moderate: • Most of the 1 or more hours a day should be either moderate- or vigorous-intensity PA • Do vigorous-intensity PA at least 3 days a week • Encourage participation in PA that are: • Age appropriate, enjoyable, offer variety
Examples of moderate-intensity aerobic activities • Children • Brisk walk, hiking • Active recreation (canoeing) • Adolescents • Brisk walk, hiking • Active recreation (canoeing) • Yard work such as raking leaves/ bagging leaves • Softball, baseball that require catching and throwing
Examples of vigorous-intensityaerobic activities • Children • Active games (tag - running and chasing) • Martial arts (karate) • Sports (soccer, hockey, basketball, tennis) • Adolescents • Active games (flag football - running and chasing) • Martial arts (karate) • Sports (soccer, hockey, basketball, tennis) • Vigorous dancing
Children and Adolescents continued • As part of 60 minutes of daily activity to include: • Muscle-strengthening: Include muscle-strengthening physical activity on at least 3 days of the week • Bone-strengthening: Include bone-strengthening physical activity on at least 3 days of the week
Examples of muscle strengthening activities • Children • Games (tug-of-war) or climbing (ropes or play-ground) • Resistance exercises (body weight or resistance bands) • Ropes, tree climb, swinging on bars/equipment • Adolescents • Climbing (pull-ups, push-ups) • Resistance exercises using hand-held weights or weight machines • Swinging on bars/equipment, rope or tree
Examples of bone strengthening activities • Children • Games (hopscotch) • Jumping rope • Gymnastics, basketball, volleyball • Adolescents • Running • Hopping, skipping, jumping • Jumping rope • Gymnastics, basketball, volleyball
Principle = F I T F – Frequency I – Intensity T – Time/Duration 2008 Guideline = minimum F – Daily I – Moderate or Vigorous T – 60 minutes Youth aerobic physical activity principle
Muscle strengthening 3 days per week Bone strengthening 3 days per week Muscle & bone strengthening principles As part of the daily 60 minutes to include:
Key Guidelines – Adults (ages 18–64) • Minimum aerobic activity for health • 2 hours and 30 minutes (150 minutes/week) moderate-intensity aerobic activity; or • 1 hour and 15 minutes (75 minutes/week) vigorous-intensity aerobic activity; or • Equal combination for 150 minutes/week • Muscle-strengthening activities that involve all major muscle groups should be performed on 2 or more days of the week
Key Guidelines – Adults continued • For additional health benefits • 5 hours (300 minutes) moderate-intensity aerobic activity a week; or • 2 hours and 30 minutes (150 minutes) vigorous-intensity aerobic activity a week; or • An equivalent combination (150 minutes)
Key Guidelines – Older adults (ages 64+) • The key guidelines for adults apply to older adults with additional qualifying guidelines: • Guideline for adults who cannot do 150 minutes/week • Balance exercise • Only use relative intensity to determine the level of effort
Principle = F I T F – Frequency I – Intensity T – Time/Duration 2008 Guideline = minimum F – Weekly I – Moderate or Vigorous T – 150 minutes/week Adult aerobic physical activity principle
Flexibility in meeting minimal aerobic 2008 Guideline Intensity Duration Frequency Moderate or ≥ 150 minutes Week Vigorous or ≥ 75 minutes Week Equivalent Combination ≥ 150 minutes Week
Summary • Most recent scientific review for Americans in the past decade • 2008 Guidelines specify a minimum of aerobic PA based on total time per week • For children and adolescents the 2008 Guidelines specify 3 days a week of bone & muscle strengthening activity • For adults the 2008 Guidelines specify 2 days a week of muscle-strengthening activity
Summary • Avoid inactivity • Some activity is better than none • Aerobic activity for children & adolescents • ≥60 mins/day moderate intensity or equivalent • Aerobic activity for adults • Substantial health benefits from medium amounts • ≥150 mins/week moderate intensity or equivalent • More health benefits from high amounts • ≥ 300 mins/week moderate intensity or equivalent
