A “bottom up” typology of parent feeding practices relates to Head Start child BMI and diet Franklin, Michelle Feese Mary Lou Lackey, Sheryl Hughes, Richard Shewchuk, John Bentley, Edmond Kabagambe UAB and Baylor College of Medicine
Background: Effect of Parent Feeding Style and Practices on BMI and Diet • Overall objective: Evaluate family-level determinants and typology of diet and BMI of normal low-income, ethnically diverse dyads of preschool children and their primary caregivers (CG) • Prior research: Impact of parenting styles in predominantly white middle class children
Methods: Caregiver-Child Dyads • Target population: 3 -to-5 year old HS children and primary caregiver (CG) (Hispanics, African American, non-Hispanic Whites) in Houston TX and Birmingham AL • CG: Person responsible for > 50 % of child’s diet outside HS; 95% females with 88% mothers • Total population: 770 CG-child dyads consented – 47% of eligible families consented – 91% consented completed all assessments (n= 704)
Methods: Assessments Caregiver (CG) child feeding practices Elicitation CG Strategies Card Sort and Rating Scale Child Feeding Strategy Clusters 24 -Hour Dietary Recalls 3/CG, 3/child (2 weekdays &1 weekend day) Collected using Nutrition Data System for Research (NDS-R) CG report of child diet when CG was present, outside HS center Defined food groups and diet score Measured CG and child height, weight and BMI
Methods: Elicitation of Parenting Strategies in Food and Feeding Domain “What are the ways parents can help their preschool child eat healthy foods? ” 8 structured nominative groups for each question with feeding experts and separate groups of CG from each race/ethnicity Distillation and cognitive interviews of nominated strategies Results: 33 distinct strategies as statements for card sorts and ratings
Methods: Card Sort Procedure Keep junk food out of house Mix FV with other foods your child likes Ask child to help with food preparation Keep child from sweets if they don’t eat their FV Show child you enjoy eating FV
Methods: CG Parenting in Food and Feeding Domain – Card sorts mapped multidimensional scaling and hierarchical cluster analysis – Derived Clusters • Child Feeding Strategies : Five • Each parent rated for their child via interview – Strategies: effectiveness of each on a 3 point scale (not very effective, a little bit effective, and very effective)
Five CG-Derived Child Feeding Strategy Clusters 1. Teachable Moments 2. Practical Methods 3. Supervise Child Diet with Contingencies 4. Restrict Junk Foods/Sweets 5. Enhance Healthy Foods Available 6.
Child Feeding Strategy Clusters 1. Teachable Moments – tell child • eating FV will make them strong and healthy as a way to get them to eat more FV • they have to try at least a couple of bites but don't have to eat it • what will happen to them if they eat too many bad foods – using mealtimes to teach about healthy eating – ask to help you with food preparation
Child Feeding Strategy Clusters 2. Practical Methods (examples) – – – add something to make F or V taste better praise when you saw them eat F or V reward with sweets if they eat their FV mix F or V with other foods your child likes give the specific F or V they like so at least they eat some parents deciding what F or V will be served, and then let child decide which of those they eat
Child Feeding Strategy Clusters 3. Supervision with Contingencies over Child Diet – make child feel guilty when they didn't eat vegetables – insist child sit at the table until they eat their F or V – keep child from • going to play if they didn't eat their F or V • having sweets if they didn't eat their F or V
Child Feeding Strategy Clusters 4. Restrict Junk Foods/Sweets – limit snacking between meals – set limits on the amount of sweet drinks your child can have – ask others to support you in getting your child to eat F or V and to not go against you by giving your child candy or sweets – keep junk food out of the house – cut back on how often your child eats fast food
Child Feeding Strategy Clusters 5. Enhance Healthy Food Availability (examples) • • • show your child that you enjoy eating FV offer F or V without forcing your child to eat them include some form of F or V or juice in most meals so that your child gets used to eating them sit at the table and eating together as a family put F or V where your child can easily reach them buy F or V instead of junk food make sure that F or V are available around your house
Authoritarian Child Feeding Practices (examples) • Physically struggle to get him/her to eat • Promise something other than food if he/she eats • Say something to show your disapproval for not eating dinner • Warn that you will take away something other than food if he/she doesn’t eat
Authoritative Child Feeding Practices (examples) • Encourage to eat by arranging the food to make it more interesting • Reason to get him/her to eat • Allow to choose the foods he/she wants to eat for dinner from foods already prepared • Compliment for eating food • Say something positive about child’s food during dinner
Permissive Child Feeding Practices (examples) • Allow to eat as much as he/she wants • Permit to decide whether he/she gets a second or third helping • Let decide how much he or she should eat off of the plate • Allow to eat what and when he/she wants to eat
Methods: Defined Food Groups Purpose: reduce number of variables in regression models while defining meaningful food subgroups 17 subgroups of NDS foods subdivided larger food groups by fat or sugar content and energy density or how normally selected or served
Defined Food Groups: CG and Child Alcohol, Added Fats, Cakes/desserts, Fried Vegetables, Non-fried Vegetables, Fruit Juice, High fat dairy, Low-energy beverages, Sugar-sweetened beverages, Fatty meats, Lean meats, Whole grains, Refined grains
Methods: Energy Adjustment of Defined Food Group Servings Goal: Examine effect of food composition on BMI Problem: Defined food group servings correlated with energy intake Approach: 1. Transform each food group to attain normality 2. Regress each food group on total energy intake using Willett’s method 3. Add mean intake of entire population to each residual from regression analysis to obtain energyadjusted food groups 4. Regress energy-adjusted food groups as independent variables on BMI as the dependent variable.
BMI: CG and HS Children 3 -5 years of age (2004 -2005) Race/ Ethnicity-Gender Obese* (%) Caregivers AA-M AA-F 57 *Adult BMI: Obese ≥ 30 18 29 44 W-M W-F Children 18 H-M H-F Obese** (%) 20 40 39 34 **Child BMI : Obese: ≥ 95 th percentile
Methods: Diet Score Sugar sweetened beverages (+), lean meats ( -) and refined grains (-) associated significantly with child BMI z-scores Purpose: combine associations between these food groups and create quartiles Sugar sweetened beverages ranked in descending order Lean meats and refined grains ranked in ascending order Dietary score: Sum of quartile ranks Higher diet score indicates better diet
Regression of Child Diet and Feeding Strategy Clusters on BMI Z-score Multiple regression with diet score and 5 child feeding strategy clusters to predict child BMI z-score Diet score ß-coefficient = – 0. 1025 (p < 0. 001) Supervision with contingency ß-coefficient = -0. 2426 (p < 0. 05) Other strategy clusters not significant

Types: Characteristics and Differences Type 4: all three factors; thus used all practices and strategies Type 2: low on demands, supervision involvement, monitoring contingency, many other strategies and practices Types 1 and 3: do not use the full array of practices Major difference of Type 4 vs. 2 is high demands and supervision with contingencies Major difference of Type 4 vs. 2, 3 is use of all practices and strategies

Conclusions (1) • Type 4 vs. 2 better child diet and BMI • Factors 1 and 3 > in Type 4 vs. 2 • High factors 2 and 3 ~ low child BMI and high child diet; factor 1 no effect • Thus factor 3 is major BMI-relevant difference in Type 4 vs. 2 • Factor 3 is high in authoritarian (“telling”) practices, supervision with contingency
Conclusions (2) • Type 4 vs. 2: ~ 2 X higher % authoritarian and authoritative styles • Both authoritarian and authoritative styles: high demandingness. • Top down and bottom up typologies: demandingness is consistent better BMI and diet relevant parenting construct • Potential of typology to target families for intervention
Future: Intervene in HS and Homes with Focus on Meal and Play Interactions
