SocioEcological Web Influencing Childhood Obesity • Individual (individual choice & responsibility) • Dietary intake, physical activity, sedentary behavior • Influenced by knowledge,attitudes, beliefs, skills • Interpersonal • Families, friends, peers • Provide social identity, support and role definition • Institutional • Schools, local sporting institutions • Rules, regulations, policies that constrain or encourage particular behaviors
SocioEcological Web Influencing Childhood Obesity Families • Community • Formal or informal local networks and norms • Resources that encourage or discourage healthy eating and physical activity • Public Policy • Local, state and federal policies or laws that regulate or effect eating practices and exercise habits
Families • Powerful and complex fields of influence embedded in a multi-layered environment • Characteristics • Foods available at home • Food/meal routines – feeding styles • Family members’ weight status and diet • Attitudes towards weight individuals’ weight status • Encouragement of physical activity • Rules regarding TV use
Families, continued • Changes in home environment • Increased use of fast foods and home replacement meals (1987-2.6 billion sales; 1992 –5.7 billion sales) • 1965 – 30% of food $ spent away from home; 1998 increased to 47% (Bowers, D.E., Food Review January-April 2000:23-29, Jekanowski, M.D. Food Review January-April 1999:32-34, Jekanowksi, M.D., Food Review January-April 1999:11-16)
Parent-Child Eating Styles • Parents shape children’s eating style • Foods available • Parent feeding styles • restriction of intake (restrict child’s access to unhealthy foods) • pressure to eat (pressure child to eat more food, typically healthy foods) • Mothers report > use of restrictive practices • With increased mothers’ own weight/eating concerns • With increased perception of daughters’ risk for weight problem • Mothers report > use of pressure to eat • With increased perception of daughter as underweight Francis, Appetite, 2001
Potential Adverse Effects • Result is to focus child away from internal cues regarding hunger and satiety • Parent assumes responsibility of initiating or terminating eating • Potential to compromise child internal awareness of hunger/fullness and appropriate responses • Limitations – white well educated sample of mothers and 5 yo daughters (n=196 Francis, Appetite, 2001
Long Term Effects of Parental Restrictive Feeding Styles • Assessment of 5-7 yo girls intake of palatable foods after a standardized lunch • Girls with large intakes of snack foods in the absence of hunger were 4.6 times more likely to be overweight at 5 and 7 years of age • For each unit of increase in parents’ reported restrictive feeding styles at 5 y, girls were 2.1 times as likely to eat in absence of hunger at age 7 (even after controlling for BMI and hunger related eating at age 5) • About 50% girls reported negative self evaluation after eating; such report linked to perceptions of being restricted from such foods Fisher, American Journal of Clinical Nutrition, 2002
Attitudes, Practices & Concerns Re: Child Feeding and Weight • Need to tailor interventions based on attitudes, practices and concerns • Build on mothers goals to provide good nutrition while balancing convenience, variety and cost • Provide strategies to overcome stress associated with providing meals • Focus parents on encouraging child-based hunger/fullness cues and appropriate responses • Recognize differences in cultural perceptions of overweight and facilitate recognition of unhealthy weights Sherry, JADA, 2004
Parent’s Perceptions Re: Children’s Weight • 3 focus groups (n=18; 13 black, 5 white); WIC participants • Mothers don’t use reported anthropometrics to assess weight, instead use reported teasing and limitations on exercise; if active with good appetite not considered overweight; overweight children described as “thick or solid”; genes considered cause independent of environment; emotionally difficult to deny or limit foods
Parent’s Perceptions Re: Children’s Weight • Cross sectional survey of 622 WIC participants with children 2-5 years • 45% low education (30% moms obese; 19% children overweight) • 55% high education (17% moms obese; 14% children overweight) • 79% of mothers failed to perceive overweight children as overweight; almost all accurately perceive their own weight • Among 99 moms with overweight children, low maternal education associated with misperception after controlling for income, maternal obesity, age, smoking and child’s age, race and gender Baughcum, Pediatrics, 2000
Media – Influences Families • Conflicting messages • Healthy-weight children shown in advertisements • negative stereotypes of overweight children among many segments of the population – including health care professionals • Unhealthy, academically unsuccessful, socially inept, unhygienic and lazy (Hill, Int J Obesity 1995, Teachman, Int J Obesity 2001) • Promotion/Advertisement of energy dense foods in all venues (TV, schools, community sites, Internet

Media Literacy Activities • 35 parents with children participating in Head Start programs; 4 week media literacy program (compared to 4 week food safety educational placebo to control for “attention”); pre-post evaluation • 4 week curriculum: advertising techniques, children’s perceptions of ads, comparing food label information to claims, role playing dealing with children’s requests • Improved parents’ understanding of TV advertising (p<.001), attitudes about TV ads (p,>001), self-efficacy (p<.001), TV mediation behaviors (p<.001), and ability to read food labels (p<.001) Hindin, JADA, 2004
Family-Based Interventions • Goals • Build parental/family support • Create supportive home environment • Epstein’s review of randomised controlled family-based interventions: “most pediatric obesity interventions are marked by small changes in relative weight or adiposity and substantial relapse”. • Example: program with dietary counseling, encouragement to exercise, and family tx for 14-18 months resulted in smaller increase in BMI than no tx controls (1.1 vs 2.8 kg/m2 @ 1 yr fu); drop out substantial Epstein, Pediatrics, 1998; Isreal, J Ped Psy, 1994
Family-Based Interventions • Quality (research based) • Quanity based on internal hunger/fullness • Continue to research family-based interventions • AND • Implement in the context of the socioecological model • Saturate communities with multidisciplinary teams • Ex: Heart Links Project
