Obesity Epidemic Why Providers Don’t Discuss Behavior Change

For Example - Smoking Cessation:

  • Too time-consuming (42%)
  • Not effective (38%)
  • No confidence in ability (22%)
  • Unpleasant personal experience (18%)
  • Low confidence in knowledge (16%)

overview physicians their patients exercise
Overview Physicians, their Patients & Exercise

47% of primary care physicians include an exercise history as part of their initial examination

Only 13% of patients report physicians giving advice about exercise

Physically active physicians are more likely to discuss exercise with their patients

Exercise (Activity) Prescription for KidsTrain Up A Child…

  • 25% of obese preschoolers become obese
  • 80% of obese 14 year-olds remain obese
  • 70% of obese children who lose weight will maintain that loss as adults
  • BMI at 18 years stronger predictor of DM2 than at ANYother age

  • Meta-analysis of 30 RCT
  • Ages: 5 - 17
  • Pre & post intervention body composition
    • Exercise “highly effective” treatment for pediatric obesity…low intensity, long duration exercise
    • Aerobic exercise combined with resistance training

Med Sci Sports Exerc, 2002

Lean body mass increases 1-3 kg

Resistance training improves strength by a range of 40-150%

Muscle fiber area 10-30%

  • Sedentary people lose large amounts of muscle mass (20-40%)
  • 6% per decade loss of Lean Body Mass (LBM)

Aerobic Activity

sufficient

to stop this loss!
