OBJECTIVES: To assess parents' liquid medication administration errors by dosing instrument type and to examine the degree to which parents' health literacy influences dosing accuracy. DESIGN: Experimental study. SETTING: Interviews conducted in a public hospital pediatric clinic in New York, New York, between October 28, 2008, and December 24, 2008. PARTICIPANTS: Three hundred two parents of children presenting for care were enrolled. MAIN OUTCOME MEASURES: Parents were observed for dosing accuracy (5-mL dose) using a set of standardized instruments (2 dosing cups [one with printed calibration markings, the other with etched markings], dropper, dosing spoon, and 2 oral syringes [one with and the other without a bottle adapter]). RESULTS: The percentages of parents dosing accurately (within 20% of the recommended dose) were 30.5% using the cup with printed markings and 50.2% using the cup with etched markings, while more than 85% dosed accurately with the remaining instruments. Large dosing errors (>40% deviation) were made by 25.8% of parents using the cup with printed markings and 23.3% of parents using the cup with etched markings. In adjusted analyses, cups were associated with increased odds of making a dosing error (>20% deviation) compared with the oral syringe (cup with printed markings: adjusted odds ratio [AOR] = 26.7; 95% confidence interval [CI], 16.8-42.4; cup with etched markings: AOR = 11.0; 95% CI, 7.2-16.8). Compared with the oral syringe, cups were also associated with increased odds of making large dosing errors (cup with printed markings: AOR = 7.3; 95% CI, 4.1-13.2; cup with etched markings: AOR = 6.3; 95% CI, 3.5-11.2). Limited health literacy was associated with making a dosing error (AOR = 1.7; 95% CI, 1.1-2.8). CONCLUSIONS: Dosing errors by parents were highly prevalent with cups compared with droppers, spoons, or syringes. Strategies to reduce errors should address both accurate use of dosing instruments and health literacy

OBJECTIVE: Controlling feeding styles in which parents regulate feeding without responding to child cues have been associated with poor self-regulation of feeding and increased weight, but have not been well studied in infancy. We sought to assess maternal perception of infant feeding cues and pressuring feeding styles in an urban Latina Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) population. METHODS: Secondary analysis of a larger study of Latina mothers participating in New York City WIC programs. We examined maternal perception of infant feeding cues and pressuring feeding style. Using logistic regression, we assessed: 1) characteristics associated with perceptions of cues and pressuring to feed, including sociodemographics, breastfeeding, and maternal body mass index; and 2) whether perceptions of cues were associated with pressuring feeding style. RESULTS: We surveyed 368 mothers (84% response rate). Most mothers perceived that babies sense their own satiety. However, 72% believed that infant crying must indicate hunger. Fifty-three percent believed that mothers should always make babies finish the bottle ("pressure to feed"). Pressuring feeding style was associated with foreign maternal country of birth (adjusted odds ratio [AOR] 3.05; 95% confidence interval [CI], 1.66-5.60) and less than a high school education (AOR 1.81; 95% CI, 1.12-2.91). Two perceptions of feeding cues were related to pressuring feeding style: belief that infant crying must indicate hunger (AOR 2.59; 95% CI, 1.52-4.42) and infant hand sucking implies hunger (AOR 1.83; 95% CI, 1.10-3.03). CONCLUSIONS: Maternal characteristics influence perception of infant hunger and satiety. Interpretation of feeding cues is associated with pressuring feeding style. Improving responsiveness to infant cues should be a component of early childhood obesity prevention.

OBJECTIVES: To test the efficacy of an electronic asthma monitoring system (AMS) to reduce pediatric emergency department (ED) visits and hospitalizations for asthma. STUDY DESIGN: Randomized clinical trial. METHODS: Families of pediatric patients with asthma aged 8 to 17 years were recruited at 6 medical centers. Children were randomly assigned to the American Medical Alert Corporation pediatric AMS or a paper diary. The numbers of and costs associated with ED visits and hospitalizations for the 2 groups in the year following randomization were compared using t tests of statistical significance. RESULTS: Of 59 children recruited to the trial, 29 were randomized to the AMS and 30 to the diary. The 2 groups were similar in demographic and clinical characteristics. During their study year, 24 AMS group members logged on a mean (SD) of 211.0 (117.3) days; 13 diary group members provided data on a mean (SD) of 136.6 (128.0) days. During the 32 months that the study was in progress, the case managers logged on a mean (SD) of 171.0 (97.2) days. Overall, 35 children had at least 1 ED visit, but only 7 children were hospitalized. The 2 groups had no statistically significant differences in the numbers of or charges associated with ED visits or hospitalizations. CONCLUSION: Electronic devices are being developed to make chronic disease management easier for patients and their families, but they should not be adopted without careful study, including randomized trials, to ascertain their use, costs, and benefits

OBJECTIVE: To determine whether maternal literacy level accounts for associations between educational level and the cognitive home environment in low-income families. DESIGN: Analysis of 369 mother-infant dyads participating in a long-term study related to early child development. SETTING: Urban public hospital. PARTICIPANTS: Low-income mothers of 6-month-old infants. MAIN EXPOSURE: Maternal literacy level was assessed using the Woodcock-Johnson III/Bateria III Woodcock-Munoz Tests of Achievement, Letter-Word Identification Test. Maternal educational level was assessed by determining the last grade that had been completed by the mother. MAIN OUTCOME MEASURE: The cognitive home environment (provision of learning materials, verbal responsivity, teaching, and shared reading) was assessed using StimQ, an office-based interview measure. RESULTS: In unadjusted analyses, a maternal literacy level of ninth grade or higher was associated with increases in scores for the overall StimQ and each of 4 subscales, whereas a maternal educational level of ninth grade or higher was associated with increases in scores for the overall StimQ and 3 of 4 subscales. In simultaneous multiple linear regression models including both literacy and educational levels, literacy continued to be associated with scores for the overall StimQ (adjusted mean difference, 3.7; 95% confidence interval, 1.7-5.7) and all subscales except teaching, whereas maternal educational level was no longer significantly associated with scores for the StimQ (1.8; 0.5-4.0) or any of its subscales. CONCLUSIONS: Literacy level may be a more specific indicator of risk than educational level in low-income families. Studies of low-income families should include direct measures of literacy. Pediatricians should develop strategies to identify mothers with low literacy levels and promote parenting behaviors to foster cognitive development in these at-risk families

OBJECTIVE: We performed a randomized, controlled trial to assess the impact of the Video Interaction Project (VIP), a program based in pediatric primary care in which videotaped interactions are used by child development specialists to promote early child development. METHOD: Ninety-nine Latino children (52 VIP, 47 controls) at risk of developmental delay based on poverty and low maternal education were assessed at age 33 months. VIP was associated with improved parenting practices including increased teaching behaviors. RESULTS: VIP was associated with lower levels of parenting stress. VIP children were more likely to have normal cognitive development and less likely to have developmental delays. CONCLUSION: This study provides evidence that a pediatric primary care-based intervention program can have an impact on the developmental trajectories of at-risk young preschool children
