OBJECTIVE: Recognition of the complexity of asthma management has led to the development of asthma treatment guidelines that include the recommendation that all pediatric asthma patients receive a written asthma action plan. We assessed the readability, suitability, and characteristics of asthma action plans, elements that contribute to the effectiveness of action plan use, particularly for those with limited literacy. METHODS: This was a descriptive study of 30 asthma action plans (27 state Department of Health (DOH)-endorsed, 3 national action plans endorsed by 6 states). Outcome measures: (1) readability (as assessed by Flesch Reading Ease, Flesch-Kincaid, Gunning Fog, Simple Measure of Gobbledygook, Forcast), (2) suitability (Suitability Assessment of Materials [SAM], adequate: >/=0.4; unsuitable: <0.4), (3) action plan characteristics (peak flow vs symptom-based, symptoms, recommended actions). RESULTS: Mean (SD) overall readability grade level was 7.2 (1.1) (range = 5.7-9.8); 70.0% were above a sixth-grade level. Mean (SD) suitability score was 0.74 (0.14). Overall, all action plans were found to be adequate, although 40.0% had an unsuitable score in at least 1 factor. The highest percent of unsuitable scores were found in the categories of layout/typography (30.0%), learning stimulation/motivation (26.7%), and graphics (13.3%). There were no statistically significant differences between the average grade level or SAM score of state DOH developed action plans and those from or adapted from national organizations. Plans varied with respect to terms used, symptoms included, and recommended actions. CONCLUSIONS: Specific improvements in asthma action plans could maximize patient and parent understanding of appropriate asthma management and could particularly benefit individuals with limited literacy skills.

OBJECTIVES: To determine whether pediatric primary care-based programs to enhance parenting and early child development reduce media exposure and whether enhanced parenting mediates the effects. DESIGN: Randomized controlled trial. SETTING: Urban public hospital pediatric primary care clinic. PARTICIPANTS: A total of 410 mother-newborn dyads enrolled after childbirth. INTERVENTIONS: Patients were randomly assigned to 1 of 2 interventions, the Video Interaction Project (VIP) and Building Blocks (BB) interventions, or to a control group. The VIP intervention comprised 1-on-1 sessions with a child development specialist who facilitated interactions in play and shared reading through review of videotapes made of the parent and child on primary care visit days; learning materials and parenting pamphlets were also provided. The BB intervention mailed parenting materials, including age-specific newsletters suggesting activities to facilitate interactions, learning materials, and parent-completed developmental questionnaires (Ages and Stages questionnaires). OUTCOME MEASURES: Electronic media exposure in the home using a 24-hour recall diary. RESULTS: The mean (SD) exposure at 6 months was 146.5 (125.0) min/d. Exposure to VIP was associated with reduced total duration of media exposure compared with the BB and control groups (mean [SD] min/d for VIP, 131.6 [118.7]; BB, 151.2 [116.7]; control, 155.4 [138.7]; P = .009). Enhanced parent-child interactions were found to partially mediate relations between VIP and media exposure for families with a ninth grade or higher literacy level (Sobel statistic = 2.49; P = .01). CONCLUSION: Pediatric primary care may represent an important venue for addressing the public health problem of media exposure in young children at a population level.

OBJECTIVE: To determine whether duration and content of media exposure in 6-month-old infants are associated with development at age 14 months. DESIGN: Longitudinal analysis of 259 mother-infant dyads participating in a long-term study related to early child development, from November 23, 2005, through January 14, 2008. SETTING: An urban public hospital. PARTICIPANTS: Mothers with low socioeconomic status and their infants. Main Exposure Duration and content of media exposure at age 6 months. MAIN OUTCOME MEASURES: Cognitive and language development at age 14 months. RESULTS: Of 259 infants, 249 (96.1%) were exposed to media at age 6 months, with mean (SD) total exposure of 152.7 (124.5) min/d. In unadjusted and adjusted analyses, duration of media exposure at age 6 months was associated with lower cognitive development at age 14 months (unadjusted: r = -0.17, P < .01; adjusted: beta = -0.15, P = .02) and lower language development (r = -0.16, P < .01; beta = -0.16, P < .01). Of 3 types of content assessed, only 1 (older child/adult-oriented) was associated with lower cognitive and language development at age 14 months. No significant associations were seen with exposure to young child-oriented educational or noneducational content. CONCLUSIONS: This study is the first, to our knowledge, to have longitudinally assessed associations between media exposure in infancy and subsequent developmental outcomes in children from families with low socioeconomic status in the United States. Findings provide strong evidence in support of the American Academy of Pediatrics recommendations of no media exposure prior to age 2 years, although further research is needed

The goal of this study was to determine whether verbal interactions between mothers and their 6-month-old infants during media exposure ('media verbal interactions') might have direct positive impacts, or mitigate any potential adverse impacts of media exposure, on language development at 14 months. For 253 low-income mother-infant dyads participating in a longitudinal study, media exposure and media verbal interactions were assessed using 24-hour recall diaries. Additionally, general level of cognitive stimulation in the home [StimQ] was assessed at 6 months and language development [Preschool Language Scale-4] was assessed at 14 months. Results suggest that media verbal interactions play a role in the language development of infants from low-income, immigrant families. Evidence showed that media verbal interactions moderated adverse impacts of media exposure found on 14-month language development, with adverse associations found only in the absence the these interactions. Findings also suggest that media verbal interactions may have some direct positive impacts on language development, in that media verbal interactions during the co-viewing of media with educational content (but not other content) were predictive of 14-month language independently of overall level of cognitive stimulation in the home

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: To assess verbal interactions related to television and other electronic media exposure among mothers and 6 month-old-infants. DESIGN: Cross-sectional analysis of 154 mother-infant dyads participating in a long-term study related to early child development. SETTING: Urban public hospital. PARTICIPANTS: Low socioeconomic status mothers of 6-month-old infants. Main Exposure Media exposure and content. MAIN OUTCOME MEASURES: Mother-infant verbal interaction associated with media exposure and maternal coviewing. RESULTS: Of 154 low socioeconomic status mothers, 149 (96.8%) reported daily media exposure in their infants, with median exposure of 120 (interquartile range, 60-210) minutes in a 24-hour period. Among 426 program exposures, mother-infant interactions were reported during 101 (23.7%). Interactions were reported most frequently with educational young child-oriented media (42.8% of programs), compared with 21.3% of noneducational young child-oriented programs (adjusted odds ratio, 0.4; 95% confidence interval, 0.1-0.98) and 14.7% of school-age/teenage/adult-oriented programs (adjusted odds ratio, 0.2; 95% confidence interval, 0.1-0.3). Among coviewed programs with educational content, mothers reported interactions during 62.7% of exposures. Coviewing was not reported more frequently for educational young child-oriented programs. CONCLUSIONS: We found limited verbal interactions during television exposure in infancy, with interactions reported for less than one-quarter of exposures. Although interactions were most commonly reported among programs with educational content that had been coviewed, programs with educational content were not more likely to be coviewed than were other programs. Our findings do not support development of infant-directed educational programming in the absence of strategies to increase coviewing and interactions

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

OBJECTIVE: There has been limited study of the association between media exposure and behavior in children younger than age 3 years. We sought to study this association in toddlers and determine whether the association varied depending on media content. METHODS: We carried out a secondary analysis of a cohort of Latino mother-infant dyads followed from birth to 33 months. We assessed media exposure at 21 and 33 months with a 24-hour recall diary that included information about the duration and content of each program watched. Behavior was assessed at 33 months by the Child Behavior Checklist. RESULTS: This analysis included 99 dyads. Results from multiple logistic regression analyses indicated associations of child behavior outcomes with 21-month total media exposure and both 21-month and 33-month exposure to noneducational young child media such as cartoons, after adjusting for maternal education, country of origin, and depressive symptoms, participation in a parenting program, and difficult child temperament. Media exposure has most consistent associations with aggressive behavior and externalizing problems. CONCLUSIONS: Media exposure was associated with externalizing behavior in Latino toddlers, with the strongest association for media oriented toward young children but without educational content. This finding has importance for both parents of young children and pediatricians as they provide anticipatory guidance

OBJECTIVE: To determine whether electronic media exposure is associated with decreased parental reading and teaching activities in the homes of preschool children. METHODS: A convenience sample presenting for well-child care to an urban hospital pediatric clinic was enrolled. Inclusion criteria were: child's age 3 to 5 years and not yet in kindergarten. Electronic media exposure (TV, movies/video, computer/video games) was assessed with a 24-hour recall diary and characterized on the basis of industry ratings. Reading aloud and teaching activities were assessed with the StimQ-Preschool READ and PIDA (Parental Involvement in Developmental Advance) subscales, respectively. RESULTS: A total of 77 families were assessed. Children were exposed to a mean (SD) of 200.8 (128.9) minutes per day of media, including 78.2 (63.7) minutes of educational young child-oriented, 62.0 (65.6) minutes of noneducational young child-oriented, 14.8 (41.4) minutes of school age/teen-oriented, and 29.2 (56.6) minutes of adult-oriented media, as well as to 16.6 (47.5) minutes of media of unknown type. A total of 79.2% watched 2 or more hours per day. Noneducational young child-oriented exposure was associated with fewer reading (semipartial correlation coefficient [SR] = -0.24, P = .02) and teaching (SR = -0.27, P = .01) activities; similar relationships were not found for other media categories. Children exposed to 2 or more hours of total electronic media per day had 1.6 (95% confidence interval, 0.4-2.9) fewer days per week of reading than children exposed to less than 2 hours (SR = -0.27, P = .01). CONCLUSIONS: This study found an association between increased exposure to noneducational young child-oriented media and decreased teaching and reading activities in the home. This association represents a mechanism by which media exposure could adversely affect development

OBJECTIVE: To assess a two-question screening tool, the Patient Health Questionnaire-2 (PHQ-2), for identifying depressive symptomatology in economically disadvantaged mothers of children in pediatric settings and to explore risk factors associated with a positive depression screen. METHODS: A convenience sample of mothers was enrolled at an inner city well-child clinic with children age 3 days to 5 years. The PHQ-2 and Edinburgh Postnatal Depression Scale (EPDS) (as reference scale) were completed. RESULTS: Ninety-four mothers participated. Agreement of the PHQ-2 and EPDS was moderate. The sensitivity of the PHQ-2 for identifying a positive screen on the EPDS was 43.5%; the specificity was 97.2%. The sensitivity of the PHQ-2 was higher for mothers with education beyond high school compared to those with less education. Perceived lack of support with child care and having two or more children were associated with a positive screen. The rate of positive screen was similar for mothers with infants and with older children. CONCLUSION: Given the low sensitivity of the PHQ-2 in lower educated mothers, additional research in populations with varying sociodemographic characteristics is indicated. Similar rates of symptoms for mothers within and beyond the postpartum period and mothers previously screened support the need for periodic screening
