Quantity, Content, and Context Matter: Associations Among Social Technology Use and Sleep Habits in Early Adolescents.

PURPOSE: This study aimed to investigate the associations of social technology access and content, bedtime behaviors, parental phone restrictions, and timing and duration of sleep on school nights in early adolescents. METHODS: Adolescents (aged 11-15 years, n = 772) in the Northeast U.S. completed an online survey during or after school in spring 2019. RESULTS: Quantity of social technology use (e.g., checking social media, problematic internet behaviors, mobile use), content viewed (e.g., emotional or violent videos, risky behaviors), and social context (e.g., bedtime behaviors, starting social media at an early age) were significantly related to later bedtimes and fewer hours of sleep on school nights. Parental rules restricting mobile phone and online use before bed and obtaining a smartphone at a later age were associated with increased sleep time and earlier bedtime. CONCLUSIONS: Quantity, content, and context of social technology use may affect sleep timing and duration in early adolescents.

Development and psychometric properties of the OCD Family Functioning (OFF) Scale.

Obsessive-compulsive disorder (OCD) influences not only patients but also family members. Although the construct of family accommodation has received attention in OCD literature, no measures of overall family functioning are currently available. The OCD Family Functioning (OFF) Scale was developed to explore the context, extent, and perspectives of functional impairment in families affected by OCD. It is a three-part, self-report measure capturing independent perspectives of patients and relatives. A total of 400 subjects were enrolled between 2008 and 2010 from specialized OCD clinics and OCD research studies. Psychometric properties of this scale were examined including internal consistency, test-retest reliability, convergent and divergent validity, and exploratory factor analyses. Both patient and relative versions of the OFF Scale demonstrated excellent internal consistency (Cronbach's alpha coefficient = 0.96). The test-retest reliability was also adequate (ICC = 0.80). Factor analyses determined that the OFF Scale comprises a family functioning impairment factor and four OCD symptom factors that were consistent with previously reported OCD symptom dimension studies. The OFF Scale demonstrated excellent convergent validity with the Family Accommodation Scale and the Work and Social Adjustment Scale. Information gathered regarding emotional impact and family role-specific impairment was novel and not captured by other examined scales. The OFF Scale is a reliable and valid instrument for the clinical and research assessment of family functioning in pediatric and adult OCD. This will facilitate the exploration of family functioning impairment as a potential risk factor, as a moderator and as a treatment outcome measure in OCD.

Yield of lumbar puncture among children who present with their first complex febrile seizure.

OBJECTIVE: To assess the rate of acute bacterial meningitis (ABM) among children who present with their first complex febrile seizure (CFS). DESIGN AND METHODS: This study was a retrospective, cohort review of patients aged 6 to 60 months who were evaluated in a pediatric emergency department (ED) between 1995 and 2008 for their first CFS. Cases were identified by using a computerized text search followed by a manual chart review. Exclusion criteria included prior history of nonfebrile seizures, an immunocompromised state, an underlying illness associated with seizures or altered mental status, or trauma. Data extracted included age, gender, seizure features, the number of previous simple febrile seizures, temperature, a family history of seizures, findings on physical examination, laboratory and imaging study results, and ED diagnosis and disposition. RESULTS: We identified 526 patients. The median age was 17 months (interquartile range: 13-24), and 44% were female. Ninety patients (17%) had a previous history of simple febrile seizures. Of the patients, 340 (64%) had a lumbar puncture (LP). The patients' median white blood cell count during a CFS was 1 cell per microL (interquartile range: 1-2), and 14 patients had CSF pleocytosis (2.7% [95% confidence interval [CI]: 1.5-4.5]). Three patients had ABM (0.9% [95% CI: 0.2-2.8]). Two had Streptococcus pneumoniae in a culture of their cerebrospinal fluid. Among these 2 patients, 1 was nonresponsive during presentation, and the other had a bulging fontanel and apnea. The third child appeared well; however, her blood culture grew S pneumoniae and failed the LP test. None of the patients for whom an LP was not attempted subsequently returned to the hospital with a diagnosis of ABM (0% [95% CI: 0, 0.9]). CONCLUSION: Few patients who experienced a CFS had ABM in the absence of other signs or symptoms.

Do parents understand growth charts? A national, Internet-based survey.

OBJECTIVE: The objective of this study was to assess parental knowledge and understanding of growth charts. METHODS: An online survey was conducted with 1000 parents selected to be demographically representative of the US population. Questions explored awareness of, knowledge of, and attitudes toward growth monitoring, as well as the ability to interpret growth chart data. RESULTS: Seventy-nine percent of parents surveyed claimed to have seen a growth chart before, with the majority thinking that they understood it well. Sixty-four percent of parents thought it was important to be shown growth charts to see how their child was growing, and 40% expressed the need to see their child's growth chart as confirmation of their health care provider's verbal interpretation. However, when provided with multiple-choice questions and answers, only 64% could identify a child's weight when shown a plotted point on a growth chart. Ninety-six percent had heard of the term "percentile," but only 68% identified the percentile of the plotted point, and only 56% could identify the definition of percentile. Up to 77% interpreted incorrectly charts containing height/weight measurements in tandem. CONCLUSIONS: Although growth charts are used frequently as visual aids to educate parents about their children's growth, many parents cannot comprehend the data. This finding is significant because many parents prefer to be shown growth charts by their health care provider, and many parents report recording their children's measurements on growth charts at home.

Glass table-related injuries in children.

OBJECTIVES: To investigate the patterns of injury sustained from glass table-related accidents to estimate whether tempered glass would prevent injuries. METHODS: We conducted a retrospective cohort analysis of all patients in an urban pediatric emergency department between October of 1995 and May for 2007 for glass table-related accidents. Data collected included age, sex, injury characteristics, examination findings, radiographic imaging, interventions, and disposition.We used a preventability score ranging from I (fully preventable injury with safety glass) to IV (unlikely to be preventable with safety glass). RESULTS: We identified 174 eligible patients during the study period. The median age was 3.4 years (interquartile range, 2.0-6.6 years); 62.1% were boys. The face was most commonly involved (45.6%) followed by lower (23.8%) and upper extremities (18.9%). Patients younger than 5 years were associated with more facial injuries (odds ratio, 6.0; 95% confidence interval, 2.9-12.6). Radiographs were obtained in 68 patients, and computed tomographic scans in 3 (total, 40.1%). Surgical repair was needed in 143 patients (82.1%), of whom 15 (10.5%) underwent procedural sedation and 8 (5.6%) required operative management. Reviewers ranked 74 patients (42.5%) as grade I, 20 patients (11.5%) as grade II, 64 patients (36.8%) as grade III, and 16 patients (9.2%) as grade IV. CONCLUSIONS: Glass table injuries are associated with significant morbidity. More than half of the injuries may have been prevented or mitigated with the use of tempered glass. Pediatricians are advised to discourage families from the purchase of nontempered glass tables, while advocating for legislation mandating the use of tempered glass.

Numeracy and communication with patients: they are counting on us.

Patient-centered interactive communication between physicians and patients is recommended to improve the quality of medical care. Numerical concepts are important components of such exchanges and include arithmetic and use of percentages, as well as higher level tasks like estimation, probability, problem-solving, and risk assessment--the basis of preventive medicine. Difficulty with numerical concepts may impede communication. The current evidence on prevalence, measurement, and outcomes related to numeracy is presented, along with a summary of best practices for communication of numerical information. This information is integrated into a hierarchical model of mathematical concepts and skills, which can guide clinicians toward numerical communication that is easier to use with patients.

Public understanding of growth charts: a review of the literature.

OBJECTIVE: To examine current knowledge about the general public's comprehension of growth charts. METHODS: A literature search was carried out to identify and analyze the findings of studies that have examined the extent to which non-healthcare professionals comprehend the information presented by growth charts. RESULTS: Few studies have examined how well parents understand growth charts. These studies have mostly been conducted in developing countries and have yielded inconclusive results. CONCLUSION: Growth charts can be useful for such purposes as growth monitoring and public health education, but their effectiveness as an educational tool depends on whether parents and caregivers comprehend the information they offer. The literature has not clearly proven that growth charts are easily understood by the general population. PRACTICE IMPLICATIONS: Further studies of the public's understanding of growth charts are needed to help guide health care providers in their use of growth charts as educational tools.
