OBJECTIVE:To examine the associations between breastfeeding intensity and underexplored features of maternal-child interaction quality over and above the influence of breastfeeding initiation. METHODS:The current study leveraged an on-going, multisite randomized controlled trial of a tiered parenting program for 462 Medicaid-eligible mothers and their infants in the United States. We examined whether breastfeeding intensity and exclusivity was associated with observed maternal sensitivity, intrusiveness, and detachment, as well as self-reported maternal verbal responsiveness, 6 months infant age. Analyses controlled for breastfeeding initiation, demographics, and early parenting experiences. RESULTS:Higher intensity breastfeeding at 6 months was significantly related to higher maternal sensitivity (β = 0.12, p = 0.004) and lower maternal intrusiveness (β = -0.10, p = 0.045). There was no significant association between breastfeeding intensity at 6 months and detachment (β = -0.02, no significant [ns]) or self-reported verbal responsiveness (β = 0.11, ns). Results were the same when intensity was measured as a dichotomous indicator for exclusive breastfeeding. Effect sizes were small-to-moderate, ranging from Cohen's d = 0.26 to 0.31. Associations did not vary by site, race/ethnicity, infant difficultness, or household poverty. CONCLUSION/CONCLUSIONS:The finding that breastfeeding intensity was significantly and independently associated with maternal sensitivity and intrusiveness is novel in the literature on low-income families from the United States. These findings have implications for breastfeeding promotion strategies and indicate that future research should explore synergistic or spillover effects of interventions aimed at maternal-child interaction quality into the infant feeding domain, particularly in the primary care setting.

Past research on predictors of participation in early childhood parenting programs suggest that families experiencing higher levels of sociodemographic adversity (e.g., younger maternal age, single parenthood, lower income or education) are less likely to participate in parenting programs. This is significant, as it may indicate that those most in need of additional support are the least likely to receive it. Data from a randomized control trial (RCT) of Smart Beginnings, an integrated, tiered model for school readiness, were used to explore predictors of attendance in Video Interaction Project (VIP) through 6 months. VIP is a primary preventive intervention delivered in tandem with pediatric well-child visits, aimed at reducing income-based disparities in early child development through promotion of responsive parent-child interactions. Using Poisson distribution models (N = 403; treatment arm, n = 201), we find that demographic, socioeconomic status (SES), and psychosocial variables are associated with program attendance but not always in the expected direction. While analyses show that first-time mothers have higher levels of program attendance as expected, we find that less-educated mothers and those with lower parenting self-efficacy have higher levels of attendance as well. The latter findings may imply that the VIP intervention is, by some indicators, effectively targeting families who are more challenging to engage and retain. Implications for pediatric-based interventions with population-level accessibility are discussed.

OBJECTIVE:Parent use of technology to manage child health issues has the potential to improve access and health outcomes. Few studies have examined how parent health literacy affects usage of Internet and cell phone technologies for health management. METHODS:Cross-sectional analysis of data collected as part of a randomized controlled experiment in 3 urban pediatric clinics. English- and Spanish-speaking parents (n=858) of children ≤8 years answered questions regarding use of and preferences related to Internet and cell phone technologies. Parent health literacy was measured using the Newest Vital Sign. RESULTS:The majority of parents were high Internet (70.2%) and cell phone (85.1%) utilizers (multiple times a day). 75.1% had limited health literacy (32.1% marginal, 43.0% low). Parents with higher health literacy had greater Internet and cell phone use (adequate vs. low: AOR=1.7[1.2-2.5]) and were more likely to use them for health management (AOR=1.5[1.2-1.8]); those with higher health literacy were more likely to use the Internet for provider communication (adequate vs. marginal vs. low: 25.0 vs. 18.0 vs. 12.0%, p=0.001) and health-related cell phone apps (40.6 vs. 29.7 vs. 16.4%, p<0.001). Overall preference for using technology for provider communication was high (∼70%) and did not differ by health literacy, although Internet and cell phone apps were preferred by higher literacy parents; no differences seen for texting. CONCLUSIONS:Health literacy-associated disparities in parent use of Internet and cell phone technologies exist, but parents' desire for use of these technologies for provider communication was overall high and did not differ by health literacy.

Children from low-income families are more likely than their higher income peers to show delays in language and literacy skills, both at school entry and across the lifespan. Programs aimed at promoting language and literacy activities in the home, particularly programs that combine distribution of print materials with support and guidance for using them, have been effective in decreasing the word gap, leading to increased school readiness and early literacy. The current study examined the impact of such a program based in pediatric healthcare, Reach Out and Read (ROR), on parents' use of community resources that also provide access to print-namely, the public library-in the context of a citywide initiative to link literacy resources for low-income families. Effects of both ROR and the library, both individually and combined, on parents' literacy activities at home were then examined. Significant associations between receiving ROR, using the public library, and parent-child book sharing were found. Implications for intervention and policy are discussed.

Children in low- and middle-income countries (LMICs) are at risk for adverse early development and school readiness outcomes; low parent literacy is common and an important contributing factor. While prevention programs have sought to improve child outcomes by promoting positive parenting practices such as reading aloud, there has been limited evidence of whether such programs have impacts for parents with low literacy in LMICs. This study investigated: (1) whether parent literacy is associated with parent-child reading aloud interactions, the overall cognitive home environment, and child language and cognitive outcomes; and (2) whether impacts of a toddler/preschool reading aloud program differ depending on parent literacy among low-income families in northern Brazil. We performed a secondary analysis of a single-blind cluster randomized controlled trial (RCT) of a parenting intervention (Universidade do Bebe [UBB]) implemented in educational childcare centers in Boa Vista, Brazil. UBB consisted of: (1) a lending library in which children's books were borrowed weekly; and (2) monthly parent workshops focused on reading aloud. Control families received usual care without the reading aloud program. Five hundred and six mother-infant dyads (279 intervention; 287 control) were enrolled at mean (SD) child age 37.4 (6.5) months. Parents and children were evaluated at baseline/enrollment and approximately 6-9 months later. Measures: (1) Predictor/moderator: parent literacy; (2) Parent outcomes: parent-child interaction during shared storybook reading; cognitive home environment; (3) Child outcomes: expressive and receptive vocabulary; IQ; working memory and short-term phonological memory. Analyses accounted for baseline performance, sociodemographics, and clustering within centers and sites. Parent literacy was positively associated with parent-child verbal/reading interactions and child developmental outcomes, supporting our first hypothesis, that low parent literacy would be associated with lower quantity and quality of parent-child reading and lower scores on assessments of child development. UBB had positive impacts on parent-child interaction, cognitive stimulation, IQ, and receptive vocabulary for both high and low literacy parents, contrary to our second hypothesis, that low parent literacy would be associated with reductions in impacts of the reading aloud intervention. The comparable impacts of a reading aloud program on parent-child verbal/reading interactions and child cognitive outcomes regardless of parent literacy level suggest that preventive interventions in LMICs should consider promotion of shared reading even for low-literacy families.

OBJECTIVE:Feeding concerns are common in the first 2 years of life and typically reflect maternal perceptions occurring within the larger context of the parent-child relationship. We aimed to determine whether (1) maternal depressive systems predicted perceived picky eating, mediated by maternal negative perceptions; (2) receipt of the Video Interaction Project (VIP) parenting intervention impacted perceived picky eating through this pathway; and (3) perceived picky eating was associated with child growth or subsequent dietary patterns. METHODS:We performed a partial longitudinal analysis of 187 low-income, predominantly Hispanic mother-child dyads enrolled in a randomized controlled trial of the VIP. Mother-infant dyads were enrolled postpartum in an urban public hospital. Participants randomized to the VIP met with an interventionist on days of well-child visits; sessions were designed to facilitate interactions in play and shared reading through provision of learning materials and review of videotaped parent-child interaction; the curriculum did not contain feeding-specific elements. We used structural equation modeling to determine direct, indirect, and total effects of maternal depressive symptoms, maternal negative perceptions, and the VIP on perceived picky eating. We then tested associations between perceived picky eating and (1) child growth, using multivariable linear regression and multilevel modeling; and (2) subsequent child dietary consumption, using multivariable multinomial logistic regression. RESULTS:Maternal depressive symptoms had significant total effects on negative maternal perceptions (β = 0.32, p < 0.001) and perceived picky eating (β = 0.21, p < 0.01) after controlling for potential confounders. This effect was partially mediated by maternal negative perceptions (indirect effect: β = 0.06, p = 0.04). When used in the model as the predictor, the VIP had a significant total effect on perceived picky eating (β = -0.16, p = 0.02), which was partially mediated by maternal depressive symptoms and negative perceptions (indirect effect: β = -0.05, p = 0.02). Perceived picky eating was not associated with child diet at age 2 years or adiposity from 6 months to 3 years. CONCLUSION/CONCLUSIONS:Maternal concerns about picky eating may reflect deeper depressive symptoms and negative perceptions of her child's behavior. Interventions designed to facilitate positive parenting in general may lessen feeding-specific concerns, such as picky eating. Although reassurance about growth and nutritional outcomes for children perceived as picky eaters is appropriate, clinicians should also consider probing for underlying symptoms of depression that could lead to eating concerns.

OBJECTIVES/OBJECTIVE:To assess parent decision-making regarding dosing tools, a known contributor to medication dosing errors, by evaluating parent dosing tool use, beliefs, and access, and the role of health literacy, with a focus on dosing cups, which are associated with an increased risk of multifold overdose. STUDY DESIGN/METHODS:Cross-sectional analysis of data collected for randomized controlled study in 3 urban pediatric clinics. English/Spanish-speaking parents (n = 493) of children ≤8 years of age enrolled. OUTCOMES/RESULTS:reported tool use, beliefs, and access. Predictor variable: health literacy (Newest Vital Sign; limited [0-3], adequate [4-6]). Multiple logistic regression analyses conducted. RESULTS:Over two-thirds of parents had limited health literacy. Oral syringes (62%) and dosing cups (22%) were most commonly used. Overall, 24% believed dosing cups were the best tool type for dosing accuracy; 99% reported having access to ≥1 dosing tools with standard measurement markings. Parents with limited health literacy had greater odds of dosing cup use (limited vs adequate: aOR = 2.4 [1.2-4.6]). Parents who believed that dosing cups are best for accuracy had greater odds of dosing cup use (aOR = 16.3 [9.0-29.3]); this belief mediated health literacy-effects on dosing cup use. CONCLUSIONS:Factors associated with dosing tool choice, including parent health literacy and beliefs are important to consider in the design of interventions to reduce dosing errors; future larger-scale studies addressing this issue are needed.
