Toddler obesity prevention: A two-generation randomized attention-controlled trial.

Rapid weight gain increases risks of obesity and associated co-morbidities. The objective was to reduce the rate of body mass index (BMI) growth (BMI z score), relative to control. Secondary outcomes were toddler-mother physical activity, mealtime interactions and fruit/vegetable intake. The randomized three-arm, eight-session, 4-month trial, conducted 2009-2013, included two intervention arms (responsive parenting and maternal lifestyle) and an attention control (home safety). Baseline and 6- and 12-month follow-up evaluations included weight and length/height, ankle accelerometry, video-recorded mealtime interactions (Emotional Availability Scales) and 24-h diet recalls (Healthy Eating Index-2015 [HEI-2015]). Analyses used linear mixed-effects models with repeated measures comparing intervention versus control changes in BMI z score. We recruited 277 racially mixed (70% African American) toddler-mother dyads (mean ages 20.1 months and 27.3 years) from US WIC and primary care clinics and randomized them into intervention versus control; 31% toddlers and 73% mothers were overweight/obese. At follow-up, changes in the rate of toddler BMI z score and maternal BMI were non-significant. Maternal lifestyle group toddlers and mothers spent 24.43 and 11.01 more minutes in physical activity (95% confidence interval [CI]: 2.55, 46.32, and 95% CI: 1.48, 20.54, respectively). Fruit intake increased in both intervention groups. Hostile mealtime interactions increased in the maternal lifestyle group, and in supplementary analyses, mealtime interactions were significantly higher in the responsive parenting group than in the maternal lifestyles group, suggesting that toddler dietary interventions include responsive parenting. Intervention effects were stronger among older versus younger toddlers. Despite no impact on weight gain, additional research should examine integrated two-generation responsive parenting and maternal lifestyle interventions among toddler-mother dyads.

The TREE Program: Promoting Positive Early Childhood Experiences During Well-Child Visits.

This feasibility study evaluated the developmental coaching TREE (Talk Read Engage Encourage) program for historically marginalized children ages 0 to 2 years, embedded within pediatric visits, examining if TREE could enhance caregiver-child interactions and increase pediatric resident report of competency and self-efficacy in coaching caregivers. Using a quasi-experimental design, a convenience sample (n = 167 families) was recruited (79 intervention; 88 control). Follow-up data were obtained from 45% of families (38 intervention; 38 control), impacted by COVID-19 attendance. Analyses demonstrated significant increases in self-reported Parent Verbal Responsivity (d = 0.68; 95% confidence interval [CI] = 0.17 to 1.18; P = .009) by intervention group caregivers. Intervention pediatric residents reported significant increases in promoting positive caregiver-child interactions and confidence in conveying child development (d = -.73; 95% CI = -1.21 to -0.22; P = .003). The TREE program is a promising practice that operationalizes promotion of relational health and positive early childhood experiences within pediatric primary care.

Systematic development and validation of a theory-based questionnaire to assess toddler feeding.

This paper describes the development and validation of a 27-item caregiver-reported questionnaire on toddler feeding. The development of the Toddler Feeding Behavior Questionnaire was based on a theory of interactive feeding that incorporates caregivers' responses to concerns about their children's dietary intake, appetite, size, and behaviors rather than relying exclusively on caregiver actions. Content validity included review by an expert panel (n = 7) and testing in a pilot sample (n = 105) of low-income mothers of toddlers. Construct validity and reliability were assessed among a second sample of low-income mothers of predominately African-American (70%) toddlers aged 12-32 mo (n = 297) participating in the baseline evaluation of a toddler overweight prevention study. Internal consistency (Cronbach's α: 0.64-0.87) and test-retest (0.57-0.88) reliability were acceptable for most constructs. Exploratory and confirmatory factor analyses revealed 5 theoretically derived constructs of feeding: responsive, forceful/pressuring, restrictive, indulgent, and uninvolved (root mean square error of approximation = 0.047, comparative fit index = 0.90, standardized root mean square residual = 0.06). Statistically significant (P < 0.05) convergent validity results further validated the scale, confirming established relations between feeding behaviors, toddler overweight status, perceived toddler fussiness, and maternal mental health. The Toddler Feeding Behavior Questionnaire adds to the field by providing a brief instrument that can be administered in 5 min to examine how caregiver-reported feeding behaviors relate to toddler health and behavior.

Early emotional caregiving environment and associations with memory performance and hippocampal volume in adolescents with prenatal drug exposure.

Early adversities, including prenatal drug exposure (PDE) and a negative postnatal emotional caregiving environment, impact children's long-term development. The protracted developmental course of memory and its underlying neural systems offer a valuable framework for understanding the longitudinal associations of pre- and postnatal factors on children with PDE. This study longitudinally examines memory and hippocampal development in 69 parent-child dyads to investigate how the early caregiving emotional environment affects children with PDE's neural and cognitive systems. Measures of physical health, drug exposure, caregiver stress, depression, and distress were collected between 0 and 24 months At age 14 years, adolescents completed multiple measures of episodic memory, and at ages 14 and 18 years, adolescents underwent magnetic resonance imaging (MRI) scans. Latent constructs of episodic memory and the caregiving environment were created using Confirmatory Factor Analysis. Multiple regressions revealed a negative emotional caregiving environment during infancy was associated with poor memory performance and smaller left hippocampal volumes at 14 years. Better memory performance at 14 years predicted larger right hippocampal volume at 18 years. At 18 years, the association between the emotional caregiving environment and hippocampal volume was moderated by sex, such that a negative emotional caregiving environment was associated with larger left hippocampal volumes in males but not females. Findings suggest that the postnatal caregiving environment may modulate the effects of PDE across development, influencing neurocognitive development.

Multi-risk infants: predicting attachment security from sociodemographic, psychosocial, and health risk among African-American preterm infants.

BACKGROUND: Ecological and transactional theories link child outcomes to accumulated risk. This study hypothesized that cumulative risk was negatively related to attachment, and that maternal sensitivity mediated linkages between risk and attachment. METHODS: One hundred and twelve high-risk African-American premature infant-mother dyads participated. Psychosocial (maternal depression, stress and self-efficacy) and sociodemographic risk (poverty, maternal education, marital status) were maternal self-report (0-4 months). Infant health risk was obtained from hospital charts. Infant-mother attachment (12 months) and maternal sensitivity (4 months) were assessed with Q-sort measures. FINDINGS: Psychosocial and sociodemographic risk, but not infant health risk, negatively related to attachment. Both were mediated by maternal sensitivity. CONCLUSIONS: The impact of risk domains on attachment security was mediated by maternal sensitivity. Results emphasize the need for early intervention programs targeting premature infants to identify and address environmental and personal factors that place parenting at risk.

Maternal perceptions of toddler body size: accuracy and satisfaction differ by toddler weight status.

OBJECTIVES: To examine (1) accuracy of maternal perceptions of toddler body size; (2) factors associated with accuracy of toddler body size; and (3) how maternal satisfaction relates to accuracy/toddler body size. DESIGN: Cross-sectional. SETTING: Low-income community sample from suburban Special Supplemental Nutrition Program for Women, Infants, and Children (WIC)/urban pediatric clinics. PARTICIPANTS: Two hundred eighty-one mother-toddler dyads (toddlers: 54.1% male; mean age, 20.2 months; 70.8% African American; 8.5% underweight [<15th weight-for-length percentile]; and 29.2% overweight [≥85th weight-for-length percentile]). MAIN EXPOSURE: Measured anthropometry (mother/toddler) and demographics. OUTCOME MEASURE: Validated toddler silhouette scale (accuracy and satisfaction). RESULTS: Nearly 70% of mothers were inaccurate in assessing their toddler's body size. Compared with mothers of healthy-weight toddlers, mothers of underweight toddlers were 9.13 times more likely to be accurate (95% CI, 2.94-28.36) and mothers of overweight toddlers were 87% less likely to be accurate (95% CI, 0.05-0.33); accuracy did not differ by toddler age, sex, or race or mother's education or weight status. More than 70% of all mothers and 81.7% of mothers of overweight toddlers were satisfied with their toddler's body size. Accurate mothers of underweight toddlers were less likely to be satisfied than accurate mothers of healthy-weight toddlers (30.0% vs 76.8%; P < .001). CONCLUSIONS: Mothers of overweight toddlers had inaccurate perceptions of their toddler's body size and were highly satisfied, suggesting a view of heavy toddlers as normative. Mothers of underweight toddlers had accurate perceptions yet were dissatisfied, suggesting recognition of their child as outside the norm. Because inaccurate perceptions begin early in toddlerhood, pediatric providers should help improve families' understanding of healthy body size. Future studies should examine how satisfaction and accuracy relate to parenting behaviors.
