“An epidemic of childhood obesity and overweight, to which social, economic, and human behaviors have contributed, threatens long-term medical, psychosocial, and financial consequences beyond US society's current capacity to respond. How the epidemic is controlled will be about the art and practice of social and behavioral change as well as the art and science of medicine.” (Lavisso-Mourey, 2007, JAMA, 298, p. 920)

Research Team(alphabetical) • Linda Bandini, PhD, RD • Carol Curtin, MSW • James Gleason, MS, PT • Melissa Maslin, MS • Aviva Must, PhD, Sarah Anderson, PhD and Keith Lividini (Tufts) • Renee Scampini, MS, RD • Elise Stokes, MS, BCBA
Parent-Supported Weight Reduction in Down Syndrome (PSWR) • Participants: Adolescents/young adults w/Down syndrome, 13-26 yrs. • Conditions/groups: • Treatment = 16 sessions over 6 mos.; follow-up at 12 months • Nutrition/Activity Education (NAE) • Parent-Supported Weight Reduction (PSWR)(= NAE + Behavioral Intervention) • Random assignment, “waves” with up to 5 participants per group. • Measurement: • BL → 10 wks. → 6 mos. → 12 mos. • Weight /height, BMI • Bioelectrical impedance: % body fat • Accelerometry (physical activity): 7-day durations • 3-day food record → categorical analysis • Knowledge pre-/post-test • Child and parent satisfaction
Nutrition & Activity Education (NAE) • Prior to sessions: • Individualized Healthy Eating Plan • Individualized Physical Activity Plan • Session features:Lecture (brief, simple), instructions, demonstrations, games, practice with feedback, reinforcement, “incentives” • Sessions: • Good Nutrition & Healthy Eating • Stay Fit, Stay Strong, Keep Moving All Day Long • Fruits, Vegetables & Low-Fat Dairy • Physical Activity: Warm-Ups & Stretching • Serving Sizes • Why is Physical Activity Good for Me? • Meal Planning • More Meals! • Activities at Home and in the Community • Snack Attack: Healthy Snacking, Mindful Eating • Strength-Building Activities • Measure Food, Measure Success! • Physical Activity Review • Eating Around Town: Eating Out • Favorite Physical Activities • Potluck Dinner Celebration
Parent Supported Weight Reduction (PSWR) • Monitoring • Daily self-recording of selected diet and physical activity behaviors • Goal setting • Weekly high priority goals • Report to group • Feedback & Reinforcement • Feedback from group • Individual reinforcement w/adolescent • Environmental arrangements (stimulus control) • Assessment • Altered arrangements • Behavioral contracting • Weekly, negotiated

Discussion • NAE were PSWR interventions were well suited to the population and well received. • Both were replicated successfully at a new site and with a new (trained) treatment team • Small pilot, but with some very suggestive findings • The PSWR group lost marginally significantly more weight than NAE alone • Small numbers precluded inclusion of a no-treatment group
Conclusions • PSWR represents a promising approach to weight loss in adolescents with Down syndrome • A full scale trial on a larger sample appears to be warranted
