OBJECTIVE: To describe infant activity at 3 months old and to test the efficacy of a primary care-based child obesity prevention intervention on promoting infant activity in low-income Hispanic families. METHODS: This study was a randomized controlled trial (n = 533) comparing a control group of mother-infant dyads receiving standard prenatal and pediatric primary care with an intervention group receiving "Starting Early," with individual nutrition counseling and nutrition and parenting support groups coordinated with prenatal and pediatric visits. Outcomes included infant activity (tummy time, unrestrained floor time, time in movement-restricting devices). Health literacy was assessed using the Newest Vital Sign. RESULTS: Four hundred fifty-six mothers completed 3-month assessments. Infant activity results were: 82.6% ever practiced tummy time; 32.0% practiced tummy time on the floor; 34.4% reported unrestrained floor time; 56.4% reported >/=1 h/d in movement-restricting devices. Inadequate health literacy was associated with reduced tummy time and unrestrained floor time. The intervention group reported more floor tummy time (OR 2.16, 95% CI 1.44-3.23) and unrestrained floor time (OR 1.69, 95% CI 1.14-2.49) compared to controls. No difference in the time spent in movement-restricting devices was found. CONCLUSIONS: Tummy time and unrestrained floor time were low. Primary care-based obesity prevention programs have potential to promote these activities.

OBJECTIVE: Hispanic parents in the United States are disproportionately affected by low health literacy and limited English proficiency (LEP). We examined associations between health literacy, LEP, and liquid medication dosing errors in Hispanic parents. METHODS: Cross-sectional analysis of data from a multisite randomized controlled experiment to identify best practices for the labeling/dosing of pediatric liquid medications (SAFE Rx for Kids study); 3 urban pediatric clinics. Analyses were limited to Hispanic parents of children aged 20% dose deviation. Predictor variables included health literacy (Newest Vital Sign) (limited = 0-3; adequate = 4-6) and LEP (speaks English less than "very well"). RESULTS: A total of 83.1% made dosing errors (mean [SD] errors per parent = 2.2 [1.9]). Parents with limited health literacy and LEP had the greatest odds of making a dosing error compared to parents with adequate health literacy who were English proficient (trials with errors per parent = 28.8 vs 12.9%; adjusted odds ratio = 2.2 [95% confidence interval 1.7-2.8]). Parents with limited health literacy who were English proficient were also more likely to make errors (trials with errors per parent = 18.8%; adjusted odds ratio = 1.4 [95% confidence interval 1.1-1.9]). CONCLUSIONS: Dosing errors are common among Hispanic parents; those with both LEP and limited health literacy are at particular risk. Further study is needed to examine how the redesign of medication labels and dosing tools could reduce literacy- and language-associated disparities in dosing errors.

Background/Purpose: Parent anxiety can affect infant experiences of procedural pain. However, little is known about other parent psychological factors associated with parent anxiety related to infant/toddler cleft and craniofacial surgery, and to what degree preoperative parent anxiety affects infant/toddler experiences of postoperative pain. Objectives 1. To identify psychological factors associated with preoperative anxiety for parents with young infants/toddlers undergoing craniofacial surgery 2. To determine whether preoperative parent anxiety is associated with infant/toddler postoperative pain Methods/Description: This was a prospective cohort study of all patients undergoing primary cleft and craniofacial surgery at a tertiary care medical center. Seventy-one consecutive parents of infants/toddlers 2-18 months were recruited for this study. Preoperative parent assessment included: anxiety (Hospital Anxiety and Depression Scale [HADS]), coping (Brief COPE), Parent Health Locus of Control scale, de novo self-efficacy around child pain, and pain knowledge. Sociodemographic data included child's age, gender; previous surgery, NICU or feeding tube; and parent age, gender, socioeconomic status, and race. Subsequent nurse-assessed child pain scores were collected for patients admitted postoperatively. Analyses included hierarchical multivariable logistic and linear regression models. Results: Parents (n=71, 90% female) of young children (mean age 6.6 mo) undergoing cleft lip/palate (n=59) or cranial vault repair (n=13) were enrolled. Only maladaptive coping (OR 1.3, p<0.01, 95% CI 1.1, 1.6), low pain management parent self-efficacy (OR 2.4, p<0.01, 95% CI 1.3, 4.5), and external locus of control (1.74, p 0.024, 95% CI 11, 2.9) were associated with high anxiety on bivariable analysis. In the final model, odds of parent preoperative anxiety was associated with differences in maladaptive coping score (aOR). Moderate/severe preoperative parental anxiety (HADS>10) was correlated with significantly higher child mean hospital pain scores in families of children undergoing cleft lip repair (1.87 point on 0-10 scale, 95% CI.42, 3.70, p =0.045). Conclusions: Infants/toddlers undergoing cleft and craniofacial surgery with highly anxious parents prior to surgery are at greater risk for higher hospital pain. Coping and self-efficacy are modifiable factors that contribute to parent anxiety before and during hospitalization and may be targets for intervention. Health locus of control could be incorporated into preoperative screening for vulnerable families

Parent perception of weight and feeding styles are associated with obesity in other racial groups but have not been explored in-depth in Chinese-American preschoolers. Cross-sectional survey of 253 Chinese-American parents with preschoolers was performed in a community clinic. Regression analysis was used to assess relationships between parental perception of weight and feeding styles. Parent under-perception of weight was common but more likely in boys than girls (chi2 = 4.91, p = 0.03). Pressuring was also greater in boys [adjusted mean difference (95% CI) 0.24 (0.004, 0.49)]. In girls, pressuring was lower for children perceived as overweight [adjusted mean difference in CFQ scores -0.75 (-1.27, -0.23)]; in boys, pressuring was high regardless of perceived child weight. Weight perceptions and feeding styles related to childhood obesity in other groups were identified in Chinese-American families. Parent under-perception of child weight and pressure to eat were more common in boys. These factors should be addressed in Chinese-American preschooler obesity prevention programs.

OBJECTIVE: Determine maternal and infant characteristics associated with adding cereal into the bottle. DESIGN: Secondary data analysis. PARTICIPANTS: Study participants were immigrant, low-income, urban mother-infant dyads (n = 216; 91% Hispanic, 19% US-born) enrolled in a randomized controlled trial entitled the Bellevue Project for Early Language, Literacy and Education Success. MAIN OUTCOME MEASURES: Maternal characteristics (age, marital status, ethnicity, primary language, country of origin, education, work status, income, depressive symptoms, and concern about infant's future weight) and infant characteristics (gender, first born, and difficult temperament). ANALYSIS: Fisher exact test, chi-square test, and simultaneous multiple logistic regression of significant (P < .05) variables identified in unadjusted analyses. RESULTS: Twenty-seven percent of mothers added cereal into the bottle. After adjusting for confounding variables identified in bivariate analyses, mothers who were single (P = .02), had moderate to severe depressive symptoms (P = .01) and perceived their infant had a difficult temperament (P = .03) were more likely to add cereal into the bottle. Conversely, mothers who expressed concern about their infants becoming overweight were less likely to add cereal (P = .02). CONCLUSIONS AND IMPLICATIONS: Health care providers should screen for adding cereal in infant bottles. Further research is needed to investigate the impact of adding cereal into the bottle on weight trajectories over time. Causal associations also need to be identified to effectively prevent this practice.

OBJECTIVE: Some experts recommend eliminating "teaspoon" and "tablespoon" terms from pediatric medication dosing instructions, as they may inadvertently encourage use of nonstandard tools (i.e. kitchen spoons), which are associated with dosing errors. We examined whether use of "teaspoon" or "tsp" on prescription labels affects parents' choice of dosing tools, and the role of health literacy and language. METHODS: Analysis of data collected as part of a controlled experiment (SAFE Rx for Kids study), which randomized English/Spanish-speaking parents (n=2110) of children <8 years old to 1 of 5 groups which varied in unit of measurement pairings on medication labels/dosing tools. Outcome assessed was parent self-reported choice of dosing tool. Parent health literacy measured using the Newest Vital Sign. RESULTS: 77.0% had limited health literacy (36.0% low, 41.0% marginal); 35.0% completed assessments in Spanish. Overall, 27.7% who viewed labels containing either "tsp" or "teaspoon" units (alone or with "mL") chose nonstandard dosing tools (i.e. kitchen teaspoon, kitchen tablespoon), compared to 8.3% who viewed "mL"-only labels (AOR=4.4[95%CI: 3.3-5.8]). Odds varied based on whether "teaspoon" was spelled out or abbreviated ("teaspoon"-alone: AOR=5.3[3.8-7.3]); "teaspoon" with mL: AOR=4.7[3.3-6.5]; "tsp" with mL (AOR=3.3[2.4-4.7]); p<0.001)). Similar findings were noted across health literacy and language groups. CONCLUSIONS: Use of teaspoon units ("teaspoon" or "tsp) on prescription labels is associated with increased likelihood of parent choice of nonstandard dosing tools. Future studies may be helpful to examine the real-world impact of eliminating teaspoon units from medication labels, and identify additional strategies to promote the safe use of pediatric liquid medications.
