This study investigated the validity and reliability of Bekesy audiometry with preschool-age children. Sixty preschool children, ages 3, 4, and 5, were chosen such that 20 children were in each of the three age groups. There were an equal number of male and female subjects in each group, and all had intelligence quotients of 90 or higher. Each subject was given a conventional pure-tone hearing evaluation, followed by a hearing test administered with a Bekesy audiometer. A retest session was conducted one week later. The results indicate that five-year-old children, when properly conditioned, can be tested with Bekesy audiometry and produce valid, reliable auditory threshold tracings. Some four-year-old children will trace a Bekesy audiometric threshold that is valid, whereas, other four-year-old children trace thresholds that are not a true representation of their actual auditory threshold. Typically, three-year-old children, as presently conditioned, are not candidates for Bekesy audiometry.

Introduction: Both monitoring and promoting PA in children, two important areas in epidemiologic research, require the use of accurate and feasible measurement tools. The Fitbit activity monitor is one of the most widely commercialized, consumer-based activity monitors and its validity and reliability has been determined in adults; however, little research has determined the validity of Fitbit activity monitor in measuring sedentary behavior and PA in preschool-age children. Hypothesis: We hypothesized that, when comparing to the direct observation (DO), the Fitbit Flex (FF) activity monitor would accurately measure the time spent in sedentary, moderate-to-vigorous PA (MVPA), and Total (light-to-vigorous) PA in preschool-age children. Methods: A total of 28 preschool age children (Female: 46%, Age: 4.6 ± 1.0 yrs, BMI: 16.4 ± 1.5 kg·m2) wore the FF (on the wrist) and were directly observed while performing a set of unstructured and structured activities with varying intensity levels such as watching TV, drawing, playing with toys, playing soccer, and shooting basket. Breath-by-breath oxygen consumption were also measured using Oxycon Mobile indirect calorimetry (OM). Data from the FF (PA counts) and the OM (VO2 ml·kg·min-1) were summarized in terms of minute-by-minute basis. The validity of FF for measuring the time spent in sedentary behavior, MVPA, and Total PA against DO was examined using three ways: (1) Pearson correlation examining the relatively agreement between FF and DO; (2) Mean absolute percent error (MAPE) examining the measurement errors of FF; and (3) One-sided equivalence test examining the absolute agreement between FF and DO by comparing the 90% confidence intervals (CI) of the estimates from the FF with the respective equivalence zone (EZ; ± 10% of the mean estimates from the DO). Results: On average, oxygen consumptions for sedentary, light, MVPA were 9.0 ± 1.6, 14.9 ± 3.9, 23.5 ± 5.5, and 33.8 ± 5.6 ml·kg·min-1, respectively. Correlations between FF and DO were consistently high for sedentary (r = 0.81, P <.001), MVPA (r = 0.62, P <.001), and Total PA (r = 0.81, P <.001). MAPEs were 8.2%, 21.1%, and 8.2% for sedentary, MVPA, and Total PA, respectively. The estimates from the FF were not significantly equivalent to those from the DO; sedentary (FF: Mean (M) = 7.8 min, 90% CI: 7.3 - 8.3 min vs. DO: M = 6 min, EZ: 5.4 - 6.6 min), MVPA (FF: M = 7.2 min, 90% CI: 6.2 - 8.2 min vs. DO: M = 12 min, EZ: 10.8 - 13.2 min), and Total PA (FF: M = 14.0 min, 90% CI: 13.6 - 14.4 min vs. DO: M = 16 min, EZ: 14.4 - 17.6 min). Conclusions: The validity of the FF was supported by the consistently high correlations with the criterion measure. However, inconsistent results from equivalence testing warrants subsequent assessment of the validity of the FF as it has a high potential for replacing research-based PA monitors in preschool-age children.

Wasting, stunting, and anemia are persistent and important forms of malnutrition in preschool-age children in the less developed world, in particular the Republic of Guinea, which was the site of a large outbreak of Ebola virus disease in 2014 to 2015. We analyzed data from 3 Demographic and Health Surveys done in Guinea in 1999, 2005, and 2012 to identify possible determinants of wasting, stunting, and anemia. All analyses, both bivariate and multivariate, were carried out separately for each of 3 age groups: less than 6 months, 6 to 23 months, and 24 to 59 months. Variables found statistically significantly associated with stunting, wasting, or anemia in bivariate analysis were placed in an age-specific logistic regression model for that outcome. Overall, anthropometric indices were available for 9228 children and hemoglobin concentrations were available for 5681 children. Logistic regression found relatively few variables associated with nutrition outcomes in children younger than 6 months. More variables were associated with nutrition outcomes in children aged 6 to 23 months. Such variables measured a wide variety of conditions, including estimated birth size, child health and nutritional status, child caring practices, mother’s nutritional and health status, and household water source and sanitation. A similarly broad range of variables was statistically significantly associated with one or more nutrition outcomes in children aged 24 to 59 months. Few of the standard infant and young child feeding indicators were associated with any nutrition outcome. Improvement in the nutritional status of young children in Guinea may require a broad range of nutrition and health interventions.

New Onset

Neurocysticercosis is a frequent cause of epilepsy and other neurologic abnormalities in all age groups, however by virtue of its prolonged incubation period as well as young children's nutritional habits, it is rarely seen in preschool-age children. The objective of this study is to report the case of a 2 ½ year-old child who presented with new-onset seizures. Her diagnostic features, including neuroradiologic findings, are described and compared with the literature. No matter how young he or she may be, every child who presents with new-onset seizures or other unexplained neurologic features and whose CT or MRI shows cystic lesions or contrast-enhancing rounded lesions should raise a suspicion of neurocysticercosis.

              Pandu is a very common prevalent disease in the society. Nutritional Iron deficiency is the most common cause of Panduroga in India. It affects all age groups but the most vulnerable are preschool-age children, pregnant women, and non-pregnant women of childbearing age. In India Malnutrition, poverty, illiteracy, contribute to anemia which can be correlated as pandu roga in Ayurveda. In Ayurveda panduroga has been described in all Samhita in detail with nidan panchak in present study. Study deals with systemic review of Panduroga from all the classics of Ayurveda.

Whole Word

Preschool-age children with phonological disorders were compared to their typically developing age peers on their ability to discriminate CVC words that differed only in the identity of the final consonant in whole-word and gated conditions. The performance of three age groups of typically developing children and adults was also assessed on the same task. Children with phonological disorders performed more poorly than age-matched peers, and younger typically developing children performed more poorly than older children and adults, even when the entire CVC word was presented. Performance in the whole-word condition was correlated with receptive vocabulary size and a measure of articulatory accuracy across all children. These results suggest that there is a complex relationship among word learning skills, the ability to attend to fine phonetic detail, and the acquisition of articulatory-acoustic and acoustic-auditory representations.

Readiness Field

In a previous MEG study of movement-related brain activity in preschool age children, we reported that pre-movement fields and sensorimotor cortex oscillations differed from those typically observed in adults, suggesting that maturation of cortical motor networks is still incomplete by late preschool age (Cheyne et al., 2014). Here we describe the same measurements in an older group of school-aged children (6 to 8 years old) and an adult control group, in addition to repeated recordings in seven children from the original study approximately two years later. Differences were observed both longitudinally within children and between age groups. Pre-movement (readiness) fields were still not present in the oldest children, however both frequency and magnitude of movement-related mu (8-12Hz) and beta (15-30Hz) oscillations demonstrated linear increases with age. In contrast, movement-evoked gamma synchronization demonstrated a step-like transition from low (30-50 Hz) to high (70-90 Hz) narrow-band oscillations, and this occurred at different ages in different children. These data provide novel evidence of linear and non-linear changes in motor cortex oscillations and delayed development of the readiness field throughout early childhood. Individual children showed large differences in maturation of movement-related brain activity, possibly reflecting differing rates of motor development.

The Impact

The article presents results of an empirical research of cognitive, affective (emotional) and behavioral components of ecological consciousness in 323 children of preschool and primary school age (6—10 years).It was found that preschool age children underestimate the impact of nature on man, but at the same time overestimate the human impact on nature. Children of this age attributed greater importance to being emotionally close with nature than children of primary school age. When choosing between the industrial, social or natural environment, children of both age groups give preference to the natural environment, leaving the industrial one the least preferred. The outcomes of this research were used to analyze the development of dialectical thinking (actions of transformation and association) in children of these age groups. As it was revealed, dialectical thinking in children of preschool age is predominantly visual. In primary school children, the visual form is replaced by conceptual and symbolic thinking, although still in an underdeveloped form. The article concludes that the first two years of school education have little influence on the development of dialectical thinking in the part that concerns actions of transformation.
