Toddler Obesity Prevention: Healthy Lifestyle Behaviors from the Beginning Maureen Black, Ph.D. Professor Department of Pediatrics mblack@peds.umaryalnd.edu 9-30-11 Objectives To describe changes in rates of obesity among young children To describe the Nutrition Transition and contribution to obesity To describe responsive feeding To describe strategies to promote healthy growth and physical activity among toddlers Over The Past 30 Years The Number of Obese Children (BMI > 95th %ile) Increased, Now Steady 1976-1980 2004-2006 20 18 Percent 15 2006-2008 17 17.6 17 13 12.4 10 5 6 5 5 0 2-5 years Ogden 2006, 2008, 2010 Double 6-12 years Triple 13-19 years Triple NUTRITIONAL STATUS: CHILDREN UNDER 5 YRS OVERWEIGHT/OBESE IN USA Overweight: BMI > 85th %ile & < 95th %ile Obese BMI > 95th %ile National Center for Health Statistics, CDC Nutrition Transition Improvements in development – urbanization, economic growth Diet More refined food, less fiber More animal source food Calorie sweeteners Eating away from home, snacks Energy More leisure time Less physical labor Popkin, 2006, 2009 Nutrition Transition Change in growth patterns Less underweight Fewer micronutrient deficiencies More overweight, obesity Change in disease patterns More chronic diseases Popkin, 2006, 2009 Energy Balance: Children Sleep Energy Out Playing Energy In Inactivity Feeding Need positive energy balance to support growth! Pediatric Obesity Prevention Obesity prevention often targets school-age children Most interventions have no effect or very small effect Not sustainable By age 2-5, > 25 % children overweight or obese Time to focus on prevention is INFANCY and TODDLERHOOD!! Ogden, JAMA, 2010; Summerbell, Cochrane, 2005 Risk Factors for Pediatric Obesity Demographics Parental overweight Obesogenic parental eating, activity patterns High gestational weight gain Rapid infant growth Low income and education levels Minority race/ethnicity Birch & Ventura, 2009 Risk Factors for Pediatric Obesity Physical activity High television watching/screen time Low physical activity Short sleep duration Eating Birch & Ventura, 2009 Formula feeding Early intro solid foods Low intake fruit & veggies High intake energy dense foods Habitual “food away from home” Large portions Frequent snacking Parent restriction, indulgence Weight-for-length Underweight, Overweight, or Within Normal???

YES!!! Wansink, Mindless Eating, 2010 Summary Children’s food preferences are influenced by internal cues and contextual factors What others are eating Familiarity of food Attractiveness of food (cartoon characters) Expectations/responsivity of parents Mealtime routines Mealtime setting - distractions RESPONSIVE PARENTING Interactive behaviors between caregivers and children • Sensitive to child’s cues • Prompt • Appropriate Parental Responsivity - applied to feeding Sensitive to child’s cues Respond to child’s cues: Prompt Appropriate Development/age Culture Situation Black & Aboud, J Nutr, 2010 Parental Responsivity is not: Giving children whatever they want. Letting children be in charge of what they want, whenever they want it. PROMOTES HEALTHY EATING & GROWTH PATTERNS RESPONSIVE FEEDING BEHAVIORS Ummm, maybe she is telling me she wants to feed herself.

Graziano, Calkins, & Keans, 2010 Preschool Interventions Can preschool interventions prevent childhood obesity? Recent review of 37 studies 8 strong design 15 moderate potential of bias 14 high potential of bias Some evidence of obesity prevention, but not strong Evidence for social and educational benefits Potential area for further research re obesity prevention – include the family! D’Onise, SSM, 2010 Hip Hop to Health - Preschoolers Efficacy trial: 14 week intervention re diet and PA taught in preschools by special educators * Smaller increases in BMI 1 and 2 years post intervention Effectiveness trial: taught by preschool teachers** More time in physical activity (accelerometer) Less screen time (parent report) No difference: diet, change in BMI z score * Fitzgibbon et al., 2005 ** Fitzgibbon et al., 2011 Toddler Overweight Prevention Study (TOPS) Toddler obesity may be linked to parenting practices (using food to manage behavior). Social Cognitive Theory: Reduce toddler obesity risk behaviors Parenting intervention? Maternal lifestyle intervention?
