OBJECTIVE:To determine whether prenatal social support was associated with infant adiposity in the first 18 months of life in a low-income, Hispanic sample, known to be at high risk of early child obesity. STUDY DESIGN/METHODS:We performed a longitudinal analysis of 262 low-income, Hispanic mother-infant pairs in the control group of the Starting Early child obesity prevention trial. Prenatal social support was measured using an item from the Maternal Social Support Index. We used multilevel modeling to predict weight-for-length z-score trajectories from birth to age 18 months and logistic regression to predict macrosomia and overweight status at ages 6, 12, and 18 months. RESULTS:High prenatal social support was independently associated with lower infant adiposity trajectories from birth to age 18 months (B = -0.40; 95% CI, -0.63 to -0.16), a lower odds of macrosomia (aOR = 0.35; 95% CI, 0.15-0.80), and a lower odds of overweight at ages 12 (aOR = 0.28; 95% CI, 0.10-0.74) and 18 months (aOR = 0.35; 95% CI, 0.14-0.89). Prenatal social support was not significantly associated with overweight status at age 6 months. CONCLUSIONS:Prenatal social support may protect against excessive infant adiposity and overweight in low-income, Hispanic families. Further research is needed to elucidate mechanisms underlying these associations and to inform preventive strategies beginning in pregnancy.

Play is essential to optimal child development because it contributes to the cognitive, physical, social, and emotional well-being of children and youth. It also offers an ideal and significant opportunity for parents and other caregivers to engage fully with children using toys as an instrument of play and interaction. The evolution of societal perceptions of toys from children's playthings to critical facilitators of early brain and child development has challenged caregivers in deciding which toys are most appropriate for their children. This clinical report strives to provide pediatric health care providers with evidence-based information that can be used to support caregivers as they choose toys for their children. The report highlights the broad definition of a toy; consideration of potential benefits and possible harmful effects of toy choices on child development; and the promotion of positive caregiving and development when toys are used to engage caregivers in play-based interactions with their children that are rich in language, pretending, problem-solving, and creativity. The report aims to address the evolving replacement of more traditional toys with digital media-based virtual "toys" and the lack of evidence for similar benefits in child development. Furthermore, this report briefly addresses the role of toys in advertising and/or incentive programs and aims to bring awareness regarding safety and health hazards associated with toy availability and accessibility in public settings, including some health care settings.

Attendance at well-child visits (WCVs) is a sine qua non of preventive care. We hypothesized that Reach Out and Read (ROR) would be associated with better WCV attendance. Parents of children 76 to 72 months at 8 clinics who did not yet have ROR reported how many WCVs their child had attended in the previous year; separate samples at the same clinics were interviewed 16 months after the ROR program was instituted. Comparing 267 parents before ROR and 254 after, the percentage who had attended the minimum number of WCVs required by the American Academy of Pediatrics periodicity schedule rose from 67.4% (180/267) to 78.3% (199/254; P < .01). This difference remained significant after controlling for multiple potential confounding factors (estimated odds ratio = 2.1, 95% confidence interval = 1.3-3.5). The largest differences were among Latino children and children of less-educated parents. Programs to enhance early literacy may increase attendance at WCVs among at-risk families.

BACKGROUND:Pediatric professionals promote shared reading to facilitate school readiness yet relatively few studies examine how parents from underserved communities consider this issue in their daily lives. We sought to understand shared reading within the broader context of parenting among Latino parents. METHODS:We conducted in-depth interviews, purposively sampling Spanish-speaking, Latina mothers of children age ≤ 3 years from an urban Federally Qualified Health Center. Interviews were recorded, transcribed, and analyzed iteratively. We allowed themes to emerge from data rather than impose an a priori framework. We sought disconfirming evidence within interviews and collected additional data to ensure no new themes were identified (saturation). RESULTS:We achieved saturation after 12 interviews. The median child age was 1.4 years. We identified 4 major themes: (1) All participants reported engaging in literacy promoting activities such as conversations, storytelling, play, and singing even if they did not read to their children daily. (2) Parents' attitudes regarding early learning and development influenced the extent to which parents engaged in shared reading with their child. (3) Participants described feelings that they ought to read daily with their children but were not and cited a variety of barriers. (4) Parents who engaged in frequent shared reading described it as a joyful and relaxed experience; parents who did not engage in shared reading described reading as instructing children or engaging in drills (e.g. teaching letters). CONCLUSION/CONCLUSIONS:Urban, Latina mothers who did not read regularly with their children nonetheless recognized its importance suggesting that existing programs have raised awareness even among underserved families. Refinement of messaging may be needed to move past raising awareness to facilitating shared reading for some parents.

The NIH-funded SAFE Rx for Kids study has identified best practices for the labeling/dosing of pediatric liquid medications. Findings support use of pictographic instructions and optimized provision of dosing tools, along with careful selection of the unit of measurement used.

Food insecurity, or the limited access to food, has been associated with maternal child feeding styles and practices. While studies in other parenting domains suggest differential and additive impacts of poverty-associated stressors during pregnancy and infancy, few studies have assessed relations between food insecurity during these sensitive times and maternal infant feeding styles and practices. This study sought to analyze these relations in low-income Hispanic mother-infant pairs enrolled in a randomized controlled trial of an early obesity prevention program (Starting Early). Food insecurity was measured prenatally and during infancy at 10 months. Food insecurity timing was categorized as never, prenatal only, infancy only, or both. Regression analyses were used to determine relations between food insecurity timing and styles and practices at 10 months, using never experiencing food insecurity as the reference, adjusting for family characteristics and material hardships. 412 mother-infant pairs completed 10-month assessments. Prolonged food insecurity during both periods was associated with greater pressuring, indulgent and laissez-faire styles compared to never experiencing food insecurity. Prenatal food insecurity was associated with less vegetable and more juice intake. If food insecurity is identified during pregnancy, interventions to prevent food insecurity from persisting into infancy may mitigate the development of obesity-promoting feeding styles and practices.

OBJECTIVE:Prenatal maternal stresses have been associated with infant temperament patterns linked to later behavioral difficulties. Material hardships, defined as inability to meet basic needs, are important prenatal stressors. Our objective was to determine the associations between prenatal material hardships and infant temperament at 10 months. METHODS:This was a longitudinal study of mother-infant pairs in a randomized controlled trial of a primary care-based early obesity prevention program (Starting Early). Independent variables representing material hardship were: housing disrepair, food insecurity, difficulty paying bills and neighborhood stress (neighborhood safety). Dependent variables representing infant temperament were assessed using questions from three subscales of the Infant Behavior Questionnaire: orienting/regulatory capacity, negative affect, and surgency/extraversion. We used linear regression to investigate associations between individual and cumulative hardships and each temperament domain, adjusting for confounders, and testing for depression as a moderator. RESULTS:412 mother-infant pairs completed 10 month assessments. 32% reported food insecurity, 26% difficulty paying bills, 35% housing disrepair and 9% neighborhood stress. In adjusted analyses, food insecurity was associated with lower orienting/regulatory capacity scores (B=-0.25, 95% CI -0.47, -0.04), as were neighborhood stress (B=-0.50, 95% CI -0.83, -0.16) and experiencing 3-4 hardships (compared with none) (B=-0.54, 95% CI -0.83, -0.21). For neighborhood stress, the association was stronger among infants of mothers with prenatal depressive symptoms (interaction term p=0.06). CONCLUSION/CONCLUSIONS:Prenatal material hardships were associated with lower orienting/regulatory capacity. These findings support the need for further research exploring how temperament relates to child behavior, and for policies to reduce prenatal material hardships.

OBJECTIVE:To determine the early impacts of pediatric primary care parenting interventions on parent cognitive stimulation in low socioeconomic status families and whether these impacts are sustained up to 1.5 years after program completion. STUDY DESIGN/METHODS:This randomized controlled trial included assignment to 1 of 2 interventions (Video Interaction Project [VIP] or Building Blocks) or to a control group. Mother-newborn dyads were enrolled postpartum in an urban public hospital. In VIP, dyads met with an interventionist on days of well-child visits; the interventionist facilitated interactions in play and shared reading through provision of learning materials and review of videotaped parent-child interactions. In Building Blocks, parents were mailed parenting pamphlets and learning materials. We compare the trajectories of cognitive stimulation for parents in VIP and control from 6 to 54 months. RESULTS:There were 546 families that contributed data. VIP was associated with enhanced reading, parent verbal responsivity, and overall stimulation at all assessment points, with analyses demonstrating a 0.38 standard deviation increase in cognitive stimulation overall. Trajectory models indicated long-term persistence of VIP impacts on reading, teaching, and verbal responsivity. CONCLUSIONS:VIP is associated with sustained enhancements in cognitive stimulation in the home 1.5 years after completion of the program and support expansion of pediatric interventions to enhance developmental trajectories of children of low socioeconomic status. TRIAL REGISTRATION/BACKGROUND:Clinicaltrials.gov: NCT00212576.

OBJECTIVES/OBJECTIVE:To determine impacts on social-emotional development at school entry of a pediatric primary care intervention (Video Interaction Project [VIP]) promoting positive parenting through reading aloud and play, delivered in 2 phases: infant through toddler (VIP birth to 3 years [VIP 0-3]) and preschool-age (VIP 3 to 5 years [VIP 3-5]). METHODS:Factorial randomized controlled trial with postpartum enrollment and random assignment to VIP 0-3, control 0 to 3 years, and a third group without school entry follow-up (Building Blocks) and 3-year second random assignment of VIP 0-3 and control 0 to 3 years to VIP 3-5 or control 3 to 5 years. In the VIP, a bilingual facilitator video recorded the parent and child reading and/or playing using provided learning materials and reviewed videos to reinforce positive interactions. Social-emotional development at 4.5 years was assessed by parent-report Behavior Assessment System for Children, Second Edition (Social Skills, Attention Problems, Hyperactivity, Aggression, Externalizing Problems). RESULTS:= .006). Multilevel models revealed significant VIP 0-3 linear effects and age × VIP 3-5 interactions. CONCLUSIONS:Phase VIP 0-3 resulted in sustained impacts on behavior problems 1.5 years after program completion. VIP 3-5 had additional, independent impacts. With our findings, we support the use of pediatric primary care to promote reading aloud and play from birth to 5 years, and the potential for such programs to enhance social-emotional development.
