Quality of life for children with haemophilia has improved since the introduction of prophylaxis. The frequency of joint haemorrhages has reduced, but the consequences of reduced bleeding on the biomechanical parameters of walking are not well understood. This study explored the differences in sagittal plane biomechanics of walking between a control group (Group 1) of normal age-matched children and children with haemophilia (Group 2) with a target ankle joint. A motion capture system and two force platforms were used to collect sagittal plane kinematic, kinetic and temporal-spatial data during walking of 14 age-matched normal children and 14 children with haemophilia aged 7-13 years. Group differences in maximum and minimum flexion/extension angles and moments of the hip, knee and ankle joints, ground reaction forces and temporal-spatial gait cycle parameters were analysed using one-way anova. Significant changes (P < 0.05) in kinematic and kinetic parameters but not temporal-spatial parameters were found in children with haemophilia; greater flexion angles and external moments of force at the knee, greater ankle plantarflexion external moments and lower hip flexion external moments. These results suggest that early biomechanical changes are present in young haemophilic children with a history of a target ankle joint and imply that lower limb joint function is more impaired than current clinical evaluations indicate. Protocols and quantitative data on the biomechanical gait pattern of children with haemophilia reported in this study provide a baseline to evaluate lower limb joint function and clinical progression.

The educational settings of 42 implanted profoundly deaf children 3 years after implantation were compared with the respective settings of 635 age-matched severely deaf and 511 profoundly deaf children with hearing aids. All implanted children received their implants before beginning school. The results revealed that 3 years after implantation. 38% (16 children) of the implanted profoundly deaf children attended mainstream schools, whereas 57% (24 children) were in a unit, or special class, in a mainstream school, and 5% (two children) were in schools for the deaf. With regard to the age-matched profoundly deaf children with hearing aids, 12% (63 children) attended mainstream schools, whereas 55% (281 children) were in a unit of a mainstream school, and 33% (167 children) were in schools for the deaf. In the group of age-matched severely deaf children, 38% (239 children) attended mainstream schools, whereas 51% (326 children) were in a unit of a mainstream school, and 11% (70 children) were in schools for the deaf. Statistical analysis revealed a highly significant difference between the educational placement of implanted children and hearing-aided profoundly deaf children (p<0.00001), whereas there was no statistically significant difference between implanted children and hearing-aided severely deaf children. In conclusion, implanted profoundly deaf children who have received their implants before beginning school have the same profile of educational placement as aided severely deaf children rather than aided profoundly deaf children of the same age in the UK. This is likely to have significant implications for the future management of profoundly deaf children and to influence future planning of educational support services.

Citrin (mitochondrial aspartate-glutamate transporter) deficiency causes the failures in both carbohydrate-energy metabolism and the urea cycle, and the alterations in the serum levels of several amino acids in the stages of newborn (NICCD) and adult (CTLN2). However, the clinical manifestations are resolved between the NICCD and CTLN2, but the reasons are still unclear. This study evaluated the serum amino acid profile in citrin-deficient children during the healthy stage. Using HPLC-MS/MS analysis, serum amino acids were evaluated among 20 citrin-deficient children aged 5-13 years exhibiting normal liver function and 35 age-matched healthy controls. The alterations in serum amino acids characterized in the NICCD and CTLN2 stages were not observed in the citrin-deficient children. Amino acids involved in the urea cycle, including arginine, ornithine, citrulline, and aspartate, were comparable in the citrin-deficient children to the respective control levels, but serum urea was twofold higher, suggestive of a functional urea cycle. The blood sugar level was normal, but glucogenic amino acids and glutamine were significantly decreased in the citrin-deficient children compared to those in the controls. In addition, significant increases of ketogenic amino acids, branched-chain amino acids (BCAAs), a valine intermediate 3-hydroxyisobutyrate, and β-alanine were also found in the citrin-deficient children. The profile of serum amino acids in the citrin-deficient children during the healthy stage showed different characteristics from the NICCD and CTLN2 stages, suggesting that the failures in both urea cycle function and energy metabolism might be compensated by amino acid metabolism. In the citrin-deficient children during the healthy stage, the characteristics of serum amino acids, including decrease of glucogenic amino acids, and increase of ketogenic amino acids, BCAAs, valine intermediate, and β-alanine, were found by comparison to the age-matched healthy control

To clarify the severity, specificity, and neurocognitive underpinnings of attention problems in very preterm children. A sample of 66 preterm (<32 weeks gestation), mean (SD) age 7.5 (0.4) years, and 66 age-matched term controls participated. Symptoms of inattention were assessed using parent and teacher-rated questionnaires, and neurocognitive measures included speed and consistency in speed of information processing, lapses of attention (tau), alerting, orienting, and executive attention, as well as verbal and visuospatial working memory. Group differences were investigated using ANOVA, and Sobel tests were used to clarify the mediating role of neurocognitive impairments on attention problems. There was a large decrease in visuospatial working memory abilities (P < .001, d = .87), and medium increases in tau (P = .002, d = 0.55) as well as parent and teacher ratings of inattention (range d = 0.40-0.56) in very preterm children compared with term peers. Tau and visuospatial working memory were significant predictors of parent (R(2) = .161, P < .001 and R(2) = .071, P = .001; respectively) and teacher (R(2) = .152, P < .001 and R(2) = .064, P = .002; respectively) ratings of inattention, and completely explained the effects of very preterm birth on attention problems. Increased lapses of attention and poorer visuospatial working memory fully account for the attention problems in very premature children at school-age. Copyright © 2012 Mosby, Inc.

Assess implicit weight bias in children 9 to 11 years old. Implicit weight bias was measured in children ages 9 to 11 ( N = 114) by using the Affect Misattribution Procedure. Participants were shown a test image of a child for 350 milliseconds followed by a meaningless fractal (200 milliseconds), and then they were asked to rate the fractal image as "good" or "bad." We used 9 image pairs matched on age, race, sex, and activity but differing by weight of the child. Implicit bias was the difference between positive ratings for fractals preceded by an image of a healthy-weight child and positive ratings for fractals preceded by an image of an overweight child. On average, 64% of abstract fractals shown after pictures of healthy-weight children were rated as "good," compared with 59% of those shown after pictures of overweight children, reflecting an overall implicit bias rate of 5.4% against overweight children ( P < .001). Healthy-weight participants showed greater implicit bias than over- and underweight participants (7.9%, 1.4%, and 0.3% respectively; P = .049). Implicit bias toward overweight individuals is evident in children aged 9 to 11 years with a magnitude of implicit bias (5.4%) similar to that in studies of implicit racial bias among adults.

The last decade saw a higher prevalence of overweight reported among food-insecure families in Canada, but no robust evidence exists on the covariate-adjusted association in children. In this study, we examined the association between hunger and overweight in Canadian students, using a propensity score matching analysis to reduce confounding. This research used data from the 2009/2010 Canadian Health Behaviour in School-aged Children study on a representative national sample of students in Grades 6 through 10. Students self-reported their height and weight and how often they have gone to school or to bed hungry due to a lack of food at home. Multivariate logistic regression modeling was conducted on the total sample (N = 17,694) and on the sample matched on propensity scores (n = 7,788). The overall prevalence of overweight among students was 20.2% with a significant difference between students who reported hunger (24.0%; 95% CI: 22.1-26.0) and students who did not (19.0%; 95% CI: 17.9-20.2). Analysis on the matched sample revealed a significant association between hunger and overweight in children (adjusted odds ratio: 1.30; 95% CI: 1.12-1.50). A substantial number of Canadian students have reported being hungry because of a lack of food at home. These students are at increased risk of overweight, regardless of their social class. Child hunger and household food insecurity exist in Canada and constitute a call for policy action at a national level.

Physical and screen-based activity in adolescents plays a crucial role in future health outcomes. Therefore, the aim of the study was to examine the associations of physical activity and screen-based activity with behavioural and psychosocial characteristics of school-aged children. Data on 11, 13 and 15 years old elementary school pupils (N=9,014; mean age=13.59) who participated in the cross-sectional Health Behaviour in School-aged Children 2009/2010 study in the Czech Republic and the Slovak Republic were analyzed. The associations of vigorous physical activity and screen-based activity with substance use, violent behaviour, eating habits and school-related outcomes adjusted for age were explored using logistic regression. Vigorous physical activity was positively associated with some of the health-related behaviours (smoking, breakfast consumption, vegetable and fruit consumption) and school related outcomes (perceived school achievement and school pressure), with gender and country based differences. Screen-based activity was significantly associated with all examined health-related behaviours and school related outcomes with only some country and gender based differences. Vigorous physical activity is positively associated with healthy development of adolescents. Screen-based behaviour shows an inverse relationship with adolescents' healthy development, especially in the group of 11 and 13 years old children. Supporting physical activity conducive environments might lead to a reduction in screen-based behaviour in adolescents and should be highlighted in health-promoting strategies.

To explore the cognitive psychological process of healthy children and children with cognitive disorder. Single Chinese character semantic priming and arithmetic tasks were delivered to 20 8-year-old healthy children, and 20 11-year-old healthy children, and 30 children with attention deficit hyperactivity disorder, 23 children with epilepsy, and 22 age-matched normal children as controls. Electroencephalography was used. Event-related potential was distilled by BESA software. (1) During the Chinese character semantic priming, the amplitudes of N2 toward the non-related words and pseudo-words in the 8-year-old group were 12.1 microV and 11.7 microV respectively, both significantly larger than those of the 11-year-old group (3.7 microV and 4.8 microV, respectively, both P<0.05). The amplitudes of N2 and P2 toward the non-related words and pseudo-words among the children with attention deficit hyperactivity disorder were both significantly lower than those in the healthy children (both P<0.05). (2) During the arithmetic task, the latency values of P2 and P3 of addition, subtraction, and multiplication in the 8-year-old group of healthy children were all significantly longer than those of the 11-year-old group of healthy children (all P<0.05). The P3 latency of the children with epilepsy was significantly longer than that of the healthy children (P<0.05). Chinese character and arithmetic cognitive waves are steady. ERP can be used to estimate the healthy children's personality index. Quantitative indicators are helpful in diagnosis and treatment of cognitive and learning disorders.

To investigate respiratory cycle-related electroencephalographic changes (RCREC) in healthy children and in children with sleep disordered breathing (SDB) during scored event-free (SEF) breathing periods of sleep. Interventional case-control repeated measurements design. Paediatric sleep laboratory in a hospital setting. Forty children with SDB and 40 healthy, age- and sex-matched children. Adenotonsillectomy in children with SDB and no intervention in controls. Overnight polysomnography; electroencephalography (EEG) power variations within SEF respiratory cycles in the overall and frequency band-specific EEG within stage 2 nonrapid eye movement (NREM) sleep, slow wave sleep (SWS), and rapid eye movement (REM) sleep. Within both groups there was a decrease in EEG power during inspiration compared to expiration across all sleep stages. Compared to controls, RCREC in children with SDB in the overall EEG were significantly higher during REM and frequency band specific RCRECs were higher in the theta band of stage 2 and REM sleep, alpha band of SWS and REM sleep, and sigma band of REM sleep. This between-group difference was not significant postadenotonsillectomy. The presence of nonrandom respiratory cycle-related electroencephalographic changes (RCREC) in both healthy children and in children with sleep disordered breathing (SDB) during NREM and REM sleep has been demonstrated. The RCREC values were higher in children with SDB, predominantly in REM sleep and this difference reduced after adenotonsillectomy.

Increased prevalence of obesity in childhood and adolescence, defined by the use of body mass index (BMI), has drawn attention towards direct measurement of body fat. To develop age-and sex-specific reference distribution of body fat in apparently healthy North-Indian children in the age group of 7-17 years and to assess agreement between obesity (defined by BMI) and excess body fat. Study subjects for this cross sectional study included 1640 apparently healthy school children (825 boys; 815 girls) aged 7-17 years. Total body fat was measured by dual energy X-rays absorptiometry (DXA). The excess body fat by DXA was defined by two methods, prevalence matching and with the use of 85th and 95th centile cutoffs. The mean ± SD, 3rd, 10th, 25th, 50th, 75th, 90th and 97th centile values of percentage body fat (PBF) are presented. PBF was highly correlated with BMI in both boys and girls (all boys: r=0.76, P<0.0001; all girls r=0.81, P<0.0001). There was no significant difference noted in PBF between boys and girls at the age of 7-8 years. From 9 years onwards, girls had significantly higher PBF than boys. Moderate degree of agreement was observed between BMI and PBF by DXA by both methods. Smoothened reference distribution of PBF for North-Indian children and adolescents in Delhi are provided. Indian children accumulate more body fat during peri-pubertal years in comparison with US children.

Auditory development in children with hearing loss, including the perception of prosody, depends on having adequate input from cochlear implants and/or hearing aids. Lack of adequate auditory stimulation can lead to delayed speech and language development. Nevertheless, prosody perception and production in people with hearing loss have received less attention than other aspects of language. The perception of auditory information conveyed through prosody using variations in the pitch, amplitude, and duration of speech is not usually evaluated clinically. This study (1) compared prosody perception and production abilities in children with hearing loss and children with normal hearing; and (2) investigated the effect of age, hearing level, and musicality on prosody perception. Participants were 16 children with hearing loss and 16 typically developing controls matched for age and gender. Fifteen of the children with hearing loss were tested while using amplification (n = 9 hearing aids, n = 6 cochlear implants). Six receptive subtests of the Profiling Elements of Prosody in Speech-Communication (PEPS-C), the Child Paralanguage subtest of Diagnostic Analysis of Nonverbal Accuracy 2 (DANVA 2), and Contour and Interval subtests of the Montreal Battery of Evaluation of Amusia (MBEA) were used. Audio recordings of the children's reading samples were rated using a perceptual prosody rating scale by nine experienced listeners who were blinded to the children's hearing status. Thirty two children, 16 with hearing loss (mean age = 8.71 yr) and 16 age- and gender-matched typically developing children with normal hearing (mean age = 8.87 yr). Assessments were completed in one session lasting 1-2 hours in a quiet room. Test items were presented using a laptop computer through loudspeaker at a comfortable listening level. For children with hearing loss using hearing instruments, all tests were completed with hearing devices set at their everyday listening setting. All PEPS

Healthy Aging in China

China has aged rapidly and the rate is accelerating in decades to come. We review positive and negative forces for healthy aging in China now and in the future. The most positive force is the spectacular growth in education over time especially for Chinese women, which should improve all dimensions of cognitive and physical health and eliminate vast gender disparities in healthy aging that currently exist. Other positive forces include increasing detection and treatment of disease and the availability of health insurance and health services so that diseases like hypertension and diabetes do not remain silent killers in China. Transparency is eased on the research level by publicly available data such as CHARLS, a sharp departure from prior scientific norm in China. Negative forces center on disturbing trends in personal health behaviors such as growing rates of smoking (among men) and obesity (for both genders), and pollution—,especially in urban centers. Public health campaigns and incentives are needed on all these fronts so that predictable long-term consequences of these behaviors on older age disease are not realized. There will not be a simple demographic fix to healthy aging in China as fertility rates are unlikely to rise much, while migration will likely continue to rise leaving growing numbers of elderly parents geographically separated from their adult children. Government policy will have to allow migration of elderly parents to live with their adult children while reducing the rigid connection of policy (health insurance and health services) with place of residence.

The objective of this study was to examine the associations between objective measures of sleep duration and sleep efficiency with the grades obtained by healthy typically developing children in math, language, science, and art while controlling for the potential confounding effects of socioeconomic status (SES), age, and gender. We studied healthy typically developing children between 7 and 11 years of age. Sleep was assessed for five week nights using actigraphy, and parents provided their child's most recent report card. Higher sleep efficiency (but not sleep duration) was associated with better grades in math, English language, and French as a second language, above and beyond the contributions of age, gender, and SES. Sleep efficiency, but not sleep duration, is associated with academic performance as measured by report-card grades in typically developing school-aged children. The integration of strategies to improve sleep efficiency might represent a successful approach for improving children's readiness and/or performance in math and languages.

To explore the characteristics of choroidal thickness (ChT) in Chinese children. A total of 144 healthy children, aged 6 years to 12 years old, were enrolled in the study. The ChT of subfovea and peripheral locations 0.5, 1.5, and 2.5 mm away from the fovea were evaluated by enhanced depth imaging optical coherence tomography. The association between subfoveal ChT and systemic, as well as ocular factors, including age, sex, height, weight, body mass index, axial length, refractive error, intraocular pressure, preterm history, and the refractive status of parents were studied. The mean subfoveal ChT was 302 ± 63 μm. In the nasal, superior, and inferior areas, the ChT of locations closer to the fovea was thicker than those farther away from the fovea (all P < 0.05); however, ChT was not significantly different among different locations in the temporal area (P = 0.16). The ChT of the nasal quadrant was significantly thinner than that of other areas (P < 0.01). Subfoveal ChT decreased with age, axial length, preterm history, and increased with height. Sex was not statistically associated with subfoveal ChT. In Chinese children, the ChT is thinnest in the nasal quadrant and thicker in central regions than in peripheral areas. The subfoveal ChT independently decreases with age, axial length, preterm history, and increases with height.

Power spectrum analysis of heart rate variability (HRV) is a noninvasive technique that provides a quantitative assessment of cardiovascular neural control. Using this technique, we studied the autonomic nervous system changes induced by sleep in 14 healthy subjects: 7 infants (mean age, 9.40 +/- 2.32 months) and 7 children (mean age, 8.93 +/- 0.65 years) during a standard all-night polysomnographic recording. Our primary aim was to assess the effect of sleep stage and age on short-term HRV during sleep in healthy infants and children. Power spectral density was estimated by autoregressive modeling over 250 consecutive R-R intervals. In this study, we mainly considered two spectral components: the high-frequency (HF) component (0.15 to 0.40 Hz), which reflects parasympathetic cardiovascular modulation; and the low-frequency (LF) component (0.04 to 0.15 Hz), generally considered due to both parasympathetic and sympathetic modulation. Heart rate was higher (p < 0.01 in all sleep stages) and total power lower (p < 0. 02) in infants than in children. HF power was higher in children than in infants (p < 0.05). In infants and children, the ratio between LF and HF powers changed with the various sleep stages (p < 0.02 in infants; p < 0.01 in children): it decreased during deep sleep and increased during rapid eye movement sleep. However, it was invariably lower in children than in infants. These findings show that the sleep stage and age both significantly influence short-term HRV during sleep in healthy infants and children. Hence, to provide unbiased results, HRV studies investigating the effects of age on autonomic nervous system activity should segment sleep into the five stages. In addition, despite a relatively small study sample, our data confirm greater parasympathetic control during sleep in children than in infants.

Empirical Implications of Matching Children With Specific Language Impairment to Children With Typical Development on Nonverbal IQ.

Earle, F Sayako; Gallinat, Erica L; Grela, Bernard G; Lehto, Alexa; Spaulding, Tammie J

This study determined the effect of matching children with specific language impairment (SLI) and their peers with typical development (TD) for nonverbal IQ on the IQ test scores of the resultant groups. Studies published between January 2000 and May 2012 reporting standard nonverbal IQ scores for SLI and age-matched TD controls were categorized into those that matched and did not match children with SLI and TD on nonverbal IQ. We then compared the nonverbal IQ scores across matching criterions within each diagnostic category. In studies that matched children on nonverbal IQ, children with SLI scored significantly higher on nonverbal IQ tests relative to children with SLI in studies that did not match on this criterion. Therefore, it appears that the nonverbal IQ performance of children with SLI is not comparable across studies that do and do not match samples on nonverbal IQ. This suggests that the practice of nonverbal IQ matching may have unintended consequences for the generalization of research findings to the broader SLI population.

Adenoid and tonsil surgeries in children: how relevant is pre-operative blood grouping and cross-matching?

As a part of pre-operative evaluation, several otolaryngologists group and cross-match blood routinely for children undergoing adenoid and tonsil surgeries. This practice has generated several debates either in support or against this practice. The aim of this study is to critically evaluate the incidence of post-tonsillectomy (with or without adenoidectomy) bleeding and blood transfusions in otherwise healthy children with adenoid/tonsil pathologies conducted in the University of Port Harcourt Teaching Hospital (UPTH). A descriptive retrospective study of children who underwent adenoid and tonsil surgeries in the Department of Ear, Nose and Throat (ENT) surgery of UPTH from January 2003 to December 2012. Children with family history of bleeding disorders and derangement of clotting profile as well as different co-morbidity like sickle cell disease were excluded from this study. The patients' data were retrieved from the registers of ENT out-patient clinics, theatre registers and patients case notes. Demographic data, indications for surgery, preoperative investigations, complications and management outcomes were recorded and analyzed. Out of 145 children that had adenoid and tonsil surgeries; only 100 met the criteria for this study. The study subjects included 65 males and 35 females (male: female ratio 1.9:1) belonging to 0-16 years age group (mean age: 3.46 ± 2.82 years). The age group of 3-5 years had the highest (n = 40, 40%) number of surgeries. Adenotonsillectomy was the commonest (n = 85, 85%) surgery performed on patients who had obstructive sleep apnea (OSA). The commonest (n = 6, 6%) complication was haemorrhage, and only few (n = 3, 3%) patients had blood transfusion. However, mortality was recorded in some (n = 3, 3%) patients. This study confirms that the incidence of post adenoidectomy/tonsillectomy bleeding in otherwise healthy children is low and rarely requires blood transfusion. We can conclude that routine preoperative blood grouping and cross-matching

The aim of this study was to investigate the developmental trajectories of attention, short-term memory, and working memory in school-aged children using a 10 min test battery of cognitive function. Participants comprised 144 typically developing children (TDC) aged 7-12 years and 24 healthy adults, divided according to age into seven groups (12 males and 12 females for each age group). Participants were assessed using CogHealth, which is a computer-based measure composed of five tasks. We measured attention, short-term memory, and working memory (WM) with visual stimulation. Each task was analyzed for age-related differences in reaction time and accuracy rate. Attention tasks were faster in stages from the age of 7-10 years. Accuracy rate of short-term memory gradually increased from 12 years of age and suddenly increased and continued to increase at 22 years of age. Accuracy rate of working memory increased until 12 years of age. Correlations were found between the ages and reaction time, and between ages and accuracy rate of the tasks. These results indicate that there were rapid improvements in attention, short-term memory, and WM performance between 7 and 10 years of age followed by gradual improvement until 12 years of age. Increase in short-term memory continued until 22 years of age. In our experience CogHealth was an easy and useful measure for the evaluation of cognitive function in school-age children.

Increasing physical activity and reducing sedentary behaviour form a large part of the treatment of paediatric obesity. However, many children today spend prolonged periods of time playing sedentary video games. Active video games (AVGs) represent a novel and child friendly form of physical activity. To measure the energy cost of playing two AVGs in children with obesity and healthy age- and gender-matched children. The energy cost of gaming and heart rates achieved during gaming conditions were compared between groups. AVG play can result in light-to-moderate intensity physical activity (2.7-5.4 metabolic equivalents). When corrected for fat-free mass those with obesity expended significantly less energy than healthy weight peers playing Nintendo Wii Fit Free Jogging (P = 0.017). No significant difference was seen between groups in the energy cost of playing Boxing. Certain AVGs, particularly those that require lower limb movement, could be used to increase total energy expenditure, replace more sedentary activities, or achieve moderate intensity physical activity among children with obesity. There seems to be some differences in how children with obesity and children of a healthy weight play AVGs. This could result in those with obesity expending less energy than their lean peers during AVG play. © 2013 The Authors. Pediatric Obesity © 2013 International Association for the Study of Obesity.

AIM To identify metabolic signatures in urine samples from healthy and inflammatory bowel disease (IBD) children. METHODS We applied liquid chromatography and gas chromatography coupled to targeted mass spectrometry (MS)-based metabolite profiling to identify and quantify bile acids and host-gut microbial metabolites in urine samples collected from 21 pediatric IBD patients monitored three times over one year (baseline, 6 and 12 mo), and 27 age- and gender-matched healthy children. RESULTS urinary metabolic profiles of IBD children differ significantly from healthy controls. Such metabolic differences encompass central energy metabolism, amino acids, bile acids and gut microbial metabolites. In particular, levels of pyroglutamic acid, glutamic acid, glycine and cysteine, were significantly higher in IBD children in the course of the study. This suggests that glutathione cannot be optimally synthesized and replenished. Whilst alterations of the enterohepatic circulation of bile acids in pediatric IBD patients is known, we show here that non-invasive urinary bile acid profiling can assess those altered hepatic and intestinal barrier dysfunctions. CONCLUSION The present study shows how non-invasive sampling of urine followed by targeted MS-based metabonomic analysis can elucidate and monitor the metabolic status of children with different GI health/disease status.

Severe growth hormone deficiency (GHD) leads to several metabolic effects in the body ranging from abnormal body composition to biochemical disturbances. However, less is known regarding these parameters in short children with GH peak levels in the lower normal range during provocation tests. Our aim was to study the metabolic profile of this group and compare it with that of healthy children of normal height. Thirty-five pre-pubertal short children (<-2.5 SDS) aged between 7 and 10years, with peak levels of GH between 7 and 14μg/L in an arginine insulin tolerance test (AITT), were compared with twelve age- and sex-matched children of normal height. The metabolic profile of the subjects was analysed by blood samples, DEXA, frequently sampled intravenous glucose tolerance test, microdialysis and stable isotope examinations of rates of glucose production and lipolysis. There were no overall significant metabolic differences between the groups. However, in the subgroup analysis, the short children with GH peaks <10μg/L had significantly lower fasting insulin levels which also correlated to other metabolic parameters. The short pre-pubertal children with GH peak levels between 7 and 14μg/L did not differ significantly from healthy children of normal height but subpopulations within this group show significant metabolic differences.

2017-01-01

It is increasingly clear that seminal sleep-affective relationships begin to take root in childhood, yet studies exploring how nighttime sleep characteristics relate to daytime affective symptoms, both in clinical and healthy populations of children, are lacking. The current study sought to explore these relationships by investigating whether trait-like and/or daily reports of affective and somatic symptoms of children with generalized anxiety disorder and matched controls relate to sleep architecture. Sixty-six children (ages 7-11; 54.4% female; 56.1% Caucasian; 18.2% biracial; 6.1% African American; 3% Asian; 16.7% Hispanic) participated including 29 with primary generalized anxiety disorder (without comorbid depression) and 37 healthy controls matched on age and race/ethnicity. Participants underwent structured diagnostic assessments including child-report measures and subsequently reported on their negative affect and somatic symptoms over the course of 1 week. Children also completed 1 night of polysomnography. Among children with generalized anxiety disorder only, greater amounts of slow wave sleep corresponded with less negative affect, and greater amounts of rapid eye movement sleep was related to more somatic complaints across the week. Similarly, for trait-like measures, more rapid eye movement sleep and shorter latency to rapid eye movement sleep were related to greater depressive symptoms in the anxious group only. The current findings suggest that physiologic sleep characteristics may contribute in direct ways to the symptom profiles of clinically anxious children. The functional relevance of such findings (e.g., how specific sleep characteristics serve to either increase or reduce long-term risk) is a vital direction for future research.

Many methods computing heart rate variability (HRV) have been applied in studies in children. Not all of these methods have a comprehensive physiological interpretation, and not all of studies are in agreement with the Task Force Standards on HRV from 1996, and the New Joint Position Statement on the advances of HRV from 2015. The study aim was to analyse HRV in the 24-h ECGs of healthy children by the Poincare plots and Lomb-Scargle periodograms, and to follow proper HRV recommendations. Additionally, we investigated the associations between age, children's sex and measured HRV indices. One hundred healthy children, aged 3–18 underwent 24-h ECG Holter monitoring. HRV was analyzed by the Poincaré plots and spectral by Lomb-Scargle periodograms of RR intervals. The Mann-Whitney test was used to compare sex differences in HRV, the van Elteren's test was used to correct for the age-gender interaction, and non-parametric Spearman correlation was applied to analyse the association between age and HRV indices. None of the HRV measures differed significantly between boys and girls. None of the HRV indices was modified by the age-gender interaction. There were statistically significant associations of age with measures of ultra-low (rho = 0.42; p < 0.0001), very low (rho = 0.35; p = 00004) and low (rho = 0.30; p = 0.0028) frequency powers, the ratio of the low to high frequency power (rho = 0.38; p = 0.0001), indices of long-term (SD2; rho = 0.37; p = 0.0002) and total (SDNN; rho = 0.33; p = 0.0008) HRV, and the contribution of the long-term HRV to total HRV (CL; rho = 0.32; p = 0.0012). In general, HRV parameters derived from the analyses of Poincaré plots and Lomb-Scargle periodograms appear not to be affected by gender, however, most of them increase with age in the 24-h ECG recordings in healthy children.

Growth retardation is common among children with epilepsy, and poor dietary intake may be one of the causes. The goal of this cross-sectional study was to compare the nutrient intake of children 1 to 8 years of age with intractable epilepsy to healthy children of the same age from the National Health and Nutrition Examination Survey 2001 to 2002 (N=1,718) and with the Dietary Reference Intakes. Children with intractable epilepsy were divided into two age groups: 1.0 to 3.9 and 4.0 to 8.9 years, to correspond with the Dietary Reference Intakes. Forty-three children with intractable epilepsy, mean age=4.7+/-2.2 years, had significantly lower intakes (P<0.05) of total energy; protein; carbohydrate; fat; dietary fiber; vitamins A, E, B-6, and B-12; riboflavin; niacin; folate; calcium; phosphorus; magnesium; zinc; copper; and selenium compared with healthy children. Thirty percent or more of the children with intractable epilepsy in both age groups had intakes below the Recommended Dietary Allowance or Adequate Intake for vitamins D, E, and K; folate; calcium; linoleic acid; and alpha-linolenic acid. Health care professionals caring for children with intractable epilepsy should be aware of this pattern of decreased nutrient intake and educate families to provide an adequate diet and/or consider vitamin/mineral supplementation.

Healthy children's perceptions of medicines: a review.

2008-06-01

Chronically ill children's perceptions of medicines have been widely studied, but healthy children's less often. However, information on healthy children's beliefs and attitudes about medicine use is needed to be able to target health education messages about medicines appropriately. A literature review was performed to determine schoolchildren's attitudes, beliefs, and knowledge about medicines; autonomy in using medicines; expectations of using medicines; and questions about medicines, so as to guide the development of a medicine education curriculum and to inform health care professionals who communicate with children. This study was a review of literature from 17 countries. The review indicated that children of school age tend to view medicines cautiously. Although age is a factor, children have very limited ideas about how medicines work and issues around medicine efficacy are confusing to them. Even young children recognize that medicines may have harmful effects and, children of all ages and cultures studied want to learn more about medicines. Autonomy in medicine use is surprisingly high and disturbing given that knowledge of medicines is poor. Primary conclusions drawn are (1) children of the same age in different cultures appear similar in their attitudes, beliefs, behaviors, and desires to learn about medicines; (2) children lack information about medicines, especially in view of their levels of autonomy; and (3) health educators and health care professionals should educate children about rational medicine use, at appropriate cognitive development levels, before the children become independent medicine users.

the aim of this study was to determine neuropsychological performance (possibly predictive of academic difficulties) and its relationship with cognitive development and maternal education in healthy preterm children of preschool age and age-matched comparison children born at term. a total of 35 infants who were born at less than 33 weeks' gestational age and who were free from major neurosensory disability (16 males, 19 females; mean gestational age 29.4wk, SD 2.2wk; mean birthweight 1257g, SD 327g) and 50 term-born comparison children (25 males, 25 females; mean birthweight 3459g, SD 585g) were assessed at 4 years of age. Cognition was measured using the Griffiths Mental Development scales while neuropsychological abilities (language, short-term memory, visual-motor and constructive spatial abilities, and visual processing) were assessed using standardized tests. Multivariable regression analysis was used to explore the effects of preterm birth and sociodemographic factors on cognition, and to adjust neuropsychological scores for cognitive level and maternal education. the mean total Griffiths score was significantly lower in preterm than in term children (97.4 vs 103.4; p<0.001). Factors associated with higher Griffiths score were maternal university education (β=6.2; 95% confidence interval [CI] 0.7-11.7) and having older siblings or a twin (β=4.0; 95% CI 0.5-7.6). At neuropsychological assessment, preterm children scored significantly lower than term comparison children in all tests except lexical production (Boston Naming Test) and visual-processing accuracy. After adjustment for cognitive level and maternal education, differences remained statistically significant for verbal fluency (p<0.05) and comprehension, short-term memory, and spatial abilities (p<0.01). neuropsychological follow-up is also recommended for healthy very preterm children to identify strengths and challenges before school entry, and to plan interventions aimed at maximizing academic

Little has been studied regarding the diets of children following LTX. The study aim was to assess and compare dietary intake and DQ of healthy children and children post-LTX. Children and adolescents (2-18 years) post-LTX (n=27) and healthy children (n=28) were studied. Anthropometric and demographic data and two 24-hour recalls (one weekend; one weekday) were collected. Intake of added sugar, HFCS, fructose, GI, and GL was calculated. DQ was measured using three validated DQ indices: the HEI-C, the DGI-CA, and the DQI-I. Although no differences in weight-for-age z-scores were observed between groups, children post-LTX had lower height-for-age z-scores than healthy children (P<.01). With the exception of vitamin B12, no significant differences in energy and macronutrient (protein, carbohydrate, and fat), added sugar, HFCS, fructose, GI, GL, and micronutrient intakes and DQ indices (HEI-C, DGI-CA, and DQI-I) between groups were observed (P>.05). The majority of children in both groups (>40%) had low DQ scores. No significant interrelationships between dietary intake, anthropometric, and demographic were found (P>.05). Both healthy and children post-LTX consume diets with poor DQ. This has implications for risk of obesity and metabolic dysregulation, particularly in transplant populations on immunosuppressive therapies. © 2017 John Wiley & Sons A/S.

Do patients with bi- or trimalleolar ankle injury show differences in motor skills and safety in comparison with healthy, active, age-matched control subjects? Prospective controlled cross-sectional study. Inclusion of 17 patients with bi- or trimalleolar ankle injury (mean 1.5 years postsurgery) and 23 healthy, active subjects of comparable age (fitness studio). Measurement instruments: motor test procedures and questionnaires. Comparison of patients and control subjects by routine daily motor function: patients < controls with the "timed 'Up & Go' test" (TUG, p = 0.011), the chair rising test and a coordination test using a gymnastic hoop (CRT and GR p > 0.05), fear of falling: patients > controls (p = 0.003) and physical activity: patients < controls (p = 0.032). There were no significant motor deficits in activities of daily life between the patients and controls, only tendencies; however, the patients showed definite limitations with an increased fear of falling and a reduced physical activity compared with the healthy control group. The resulting differences should be positively influenced by appropriate enhancement of training or participation in sports courses. The aim is to achieve a similar quality of life by a perception of safety and trust in one's own motor skills.

Mexico has the highest and most alarming rates of childhood obesity worldwide. A study conducted in the State of Mexico revealed that one of every three children presents overweight or obesity. The objective of this paper is to provide a step-by-step description of the design and implementation of an educational intervention to promote healthy eating and physical activity called "Healthy Recess". The educational intervention was designed using the six stages of the Health Communication Process. This methodological model allowed identifying the needs of school-age children on information and participation in activities. In order to improve the strategy, adjustments were made to the print and audiovisual materials as well as to assessment tools. Typography was modified as well as the color of the images in student's workbook and facilitator's; special effects of the videos were increased; the narration of the radio spots was improved and common words and phrases were included. The Health Communication Process is an effective tool for program planners to design interventions aimed at managing prevalent health problems such as overweight and obesity in school-age children.

This cross sectional study was performed to evaluate dental ages and incidence of dental anomalies in children treated for acute lymphoblastic leukemia (ALL). A total of 25 ALL patient who passed at least 2 years of chemotherapy and 25 healthy sex and age matched children were evaluated. Dental age as well as dental anomalies in shape, size, number, and structure was recorded based on their panoramic radiographies which were taken for dental purposes. The number of dental anomalies significantly increased in ALL treated children. Seven ALL cases (28%) in compression to only one (4%) in control group had at least one dental anomaly. However, there was neither statistically significant differences between the mean of dental (p=0.32) and chronologic age (p=0.12) in both groups, nor between dental age of cases and control group (p=0.62).The age at the onset of treatment as well as treatment durations has not affected dental age and the incidence of dental anomalies significantly (p<0.05). Chemotherapy in children results in emergence of dental anomaly. Dental age, maturity, and development process however seems to be independent from chemotherapy.

2016-01-01

Whereas research has indicated that children with Down syndrome (DS) imitate demonstrated actions over short delays, it is presently unknown whether children with DS recall information over lengthy delays at levels comparable with typically developing (TD) children matched on developmental age. In the present research, 10 children with DS and 10 TD children participated in a two-session study to examine basic processes associated with hippocampus-dependent recall memory. At the first session, the researcher demonstrated how to complete a three-step action sequence with novel stimuli; immediate imitation was permitted as an index of encoding. At the second session, recall memory was assessed for previously modelled sequences; children were also presented with two novel three-step control sequences. The results indicated that group differences were not apparent in the encoding of the events or the forgetting of information over time. Group differences were also not observed when considering the recall of individual target actions at the 1-month delay, although TD children produced more target actions overall at the second session relative to children with DS. Group differences were found when considering memory for temporal order information, such that TD children evidenced recall relative to novel control sequences, whereas children with DS did not. These findings suggest that children with DS may have difficulty with mnemonic processes associated with consolidation/storage and/or retrieval processes relative to TD children. © 2015 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

Although rotavirus and norovirus cause nearly 40% of severe endemic acute gastroenteritis (AGE) in children <5 years of age in the United States, there are limited data on the etiologic role of other enteric viruses in this age group. We conducted active population-based surveillance in children presenting with AGE to hospitals, emergency departments, and primary care clinics in 3 US counties. Stool specimens from these children and from age-matched healthy controls collected between October 2008 and September 2009 were tested for enteric adenovirus, astrovirus, sapovirus, parechovirus, bocavirus, and aichivirus. Typing was performed by sequencing and phylogenetic analysis. Adenovirus, astrovirus, sapovirus, parechovirus, bocavirus, and aichivirus were detected in the stool specimens of 11.8%, 4.9%, 5.4%, 4.8%, 1.4%, and 0.2% of patients with AGE and 1.8%, 3.0%, 4.2%, 4.4%, 2.4%, and 0% of healthy controls, respectively. Adenovirus (type 41), astrovirus (types 1, 2, 3, 4, and 8), sapovirus (genogroups I and II), parechovirus (types 1, 3, 4, and 5), and bocavirus (types 1, 2, and 3) were found cocirculating. Adenovirus, astrovirus, and sapovirus infections were detected in 22.1% of the specimens from children <5 years of age who had medical visits for AGE and tested negative for rotavirus and norovirus. No causal role for parechovirus and bocavirus was found.

Diet qualities: healthy and unhealthy aspects of diet quality in preschool children.

Diet quality indexes combine the healthy and unhealthy aspects of diet within a single construct, but few studies have evaluated their association. Emerging evidence suggests that predictors differ for the more and less healthy components of children's diets. Our objectives were to determine whether preschool-aged children's frequency of eating healthy foods was inversely related to their intake of unhealthy foods and to determine whether this differed by household income, maternal education, or child race-ethnicity. We analyzed data from a representative sample of 8900 US children (mean age: 52.5 mo) who were born in 2001 and participated in the Early Childhood Longitudinal Study-Birth Cohort. Primary caregivers reported the frequency with which children consumed fruit, vegetables, milk, juice, sugar-sweetened beverages (SSBs), fast food, sweets, and salty snacks in the past week. Response options ranged from none to ≥4 times/d. We created healthy (fruit, vegetables, milk) and unhealthy (SSBs, fast food, sweets, salty snacks) diet scores. Healthy diet behaviors were defined as ≥2 daily servings of fruit, vegetables, and milk. The prevalence of consuming fruit, vegetables, and milk ≥2 times/d (i.e., having 3 healthy diet behaviors) was 18.5%, and a similar proportion (17.6%) of children had none of these healthy behaviors. Contrary to our hypotheses, children with more healthy diet behaviors did not have lower unhealthy diet scores. The intake of healthy foods was not inversely associated with unhealthy foods overall or within any subgroup. Overall, the Spearman rank correlation between healthy and unhealthy diet scores was positive (r = 0.09). From the lowest to the highest strata of household income, these correlations were 0.12, 0.14, 0.14, 0.05, and 0.00, respectively. No evidence was found in US preschool-aged children of an inverse association between eating healthy and unhealthy foods. The implications of combining healthy and unhealthy aspects of diet

Decreased information processing speed (IPS) is frequently reported in pediatric multiple sclerosis (MS) patients. The computerized version of the Symbol Digit Modalities Test (c-SDMT) measures IPS over eight consecutive trials per session and additionally captures changes in performance within the session. Here, we establish normative c-SDMT performance and test-retest reliability in healthy children (HC) and explore differences in the overall c-SDMT-performance between HC and MS patients. This cross-sectional study included 478 HC (237 female, 49.5%) divided into five age groups (2 years each), and 27 MS patients (22 female, 81.5%) aged 8-18 years. The average time to complete the c-SDMT increased with age (|r| 0.70, 95% CI -0.74, -0.64). Test-retest reliability was high (ICC = 0.91) in HC. The total time to complete the c-SDMT did not differ between children with MS and sex- and age- matched HC (p = 0.23). However, MS patients were less likely to show faster performance across all the successive eight trials compared to HC (p = 0.0001). Healthy children demonstrate faster IPS with increasing age, as well as during successive trials of the c-SDMT. The inability of pediatric MS patients to maintain the increase in processing speed over successive trials suggests a reduced capacity for procedural learning, possibly resulting from cognitive fatigue.

Mother-child language style matching predicts children's and mothers' emotion reactivity.

Co-regulation of behavior occurring within parent-child attachment relationships is thought to be the primary means through which children develop the capacity to regulate emotion, an ability that is protective across development. Existing research on parent-child co-regulation focuses predominantly on parent-infant dyads, and operationalizes co-regulation as the matching of facial expressions; however, matching can occur on other behaviors, including vocal tone, body movement, and language. Studies with young children find that greater matching is associated with children's lower emotion reactivity, but with unknown impacts on parents. In this study we examine a recently-developed metric of behavioral matching, language style matching (LSM), a composite measure of the similarity of function word use in spoken or written language between two or more people. We test whether LSM between mothers and their school-aged children is associated with children's and mothers' physiological and subjective emotion reactivity. Children completed a standardized stressor task while their mothers observed; children's and mother's cortisol and cardiovascular reactivity were assessed, as were their subjective reports of emotion reactivity. Following the stressor, children and mothers completed independent interviews about the experience, later assessed for LSM. Higher mother-child LSM was associated with lower emotion reactivity (lower cortisol reactivity, lower reports of negative emotion) for children, and with higher maternal cardiovascular but not cortisol or subjective reactivity. Further, higher LSM was more strongly associated with lower child cortisol reactivity when mothers were more reactive themselves. We conclude that mother-child LSM, thought to reflect a history of co-regulated interaction, confers protective benefits for children, but heightened reactivity for mothers.

The fast food industry has been increasingly criticized for creating brand loyalty in young consumers. Food marketers are well versed in reaching children and youth given the importance of brand loyalty on future food purchasing behavior. In addition, food marketers are increasingly targeting the Hispanic population given their growing spending power. The fast food industry is among the leaders in reaching youth and ethnic minorities through their marketing efforts. The primary objective of this study was to determine if young children recognized fast food restaurant logos at a higher rate than other food brands. Methods Children (n = 155; 53% male; 87% Hispanic) ages 4-8 years were recruited from elementary schools and asked to match 10 logo cards to products depicted on a game board. Parents completed a survey assessing demographic and psychosocial characteristics associated with a healthy lifestyle in the home. Results Older children and children who were overweight were significantly more likely to recognize fast food restaurant logos than other food logos. Moreover, parents' psychosocial and socio-demographic characteristics were associated with the type of food logo recognized by the children. Conclusions Children's high recognition of fast food restaurant logos may reflect greater exposure to fast food advertisements. Families' socio-demographic characteristics play a role in children's recognition of food logos.

The objective of this study is to assess the autonomic nerve heart rate regulation system at rest and its immediate response to paced breathing among patients with complex regional pain syndrome (CRPS) as compared with age-matched healthy controls. Quasiexperimental. Outpatient clinic. Ten patients with CRPS and 10 age- and sex-matched controls. Participants underwent Holter ECG (NorthEast Monitoring, Inc., Maynard, MA, USA) recording during rest and biofeedback-paced breathing session. Heart rate variability (HRV), time, and frequency measures were assessed. HRV and time domain values were significantly lower at rest among patients with CRPS as compared with controls. A significant association was noted between pain rank and HRV frequency measures at rest and during paced breathing; although both groups reduced breathing rate significantly during paced breathing, HRV time domain parameters increased only among the control group. The increased heart rate and decreased HRV at rest in patients with CRPS suggest a general autonomic imbalance. The inability of the patients to increase HRV time domain values during paced breathing may suggest that these patients have sustained stress response with minimal changeability in response to slow-paced breathing stimuli.

In healthy children, there is a paucity of information on the growth of the brainstem and thalamus measured by anatomical magnetic resonance imaging. The relationships of age, gender, and age by gender with brainstem and thalamus volumes were analyzed from magnetic resonance brain images of 122 healthy children and adolescents (62 males, 60 females; ages four to seventeen). Results showed that age is a significant predictor of brainstem and thalamus volumes. The volume of the brainstem increases with age, while thalamus volume declines with age. The volumes of right thalami are significantly larger than that of left in both genders with greater rightward asymmetry and greater thalamus/grey matter ratio in females. Males have larger brainstems, but these differences are not significant when covarying for cerebral volumes. Larger thalami were associated with higher verbal IQ. This normative pediatric data is of value to researchers who study these regions in neurodevelopmental disorders. PMID:21954432

In this study, the authors' goal was to compare head circumference in hydrocephalic children during the first 4 years of ventriculoperitoneal (VP) shunt treatment with data on healthy children and to investigate predictors of skull growth in children with a VP shunt. Children from western Sweden treated for hydrocephalus with an initial VP shunt insertion performed between 2001 and 2006 who were younger than 12 months of age at the time of surgery were included. Children with major brain malformations, craniofacial syndromes, large cysts, and tumors were excluded. Head circumference, weight, and height at 9 defined ages up to 4 years were obtained and compared with data from a reference population of 3650 healthy children using the standard deviation score (SDS). Predictors (length, weight, etiology of hydrocephalus, valve type, number of revisions, valve setting, number of adjustments, and time of first surgery) for head circumference SDS and changes in head circumference SDS from shunt insertion at 1 year to last measurement were analyzed using bivariate and multiple linear regression analysis. Fifty children were included. The mean SDSs for head circumference in shunt-treated compared with healthy children were 1.95 ± 2.50 at shunt insertion (p < 0.001, n = 44), 0.38 ± 1.97 at 1 year (p = 0.27, n = 33), -0.96 ± 2.05 at 2 years (p = 0.046, n = 21), -1.39 ± 2.25 at 3 years (p = 0.026, n = 16), and 0.63 ± 3.34 at 4 years (p = 0.73, n = 4). Significant predictors for low head circumference SDS at 1 year of age were low weight (p = 0.002) and short height (p = 0.022) and at last measurement low weight (p < 0.0001), short height (p = 0.002), and 1-4 shunt revisions (p = 0.034). A significant predictor for change in head circumference SDS from shunt insertion to 1 year of age was the number of shunt valve revisions (p = 0.04) and at last measurement an etiology of intraventricular hemorrhage (p = 0.0058). Shunt-treated children have smaller head circumferences at

2016-01-01

Brain activity is complex; a reflection of its structural and functional organization. Among other measures of complexity, the fractal dimension is emerging as being sensitive to neuronal damage secondary to neurological and psychiatric diseases. Here, we calculated Higuchi’s fractal dimension (HFD) in resting-state eyes-closed electroencephalography (EEG) recordings from 41 healthy controls (age: 20–89 years) and 67 Alzheimer’s Disease (AD) patients (age: 50–88 years), to investigate whether HFD is sensitive to brain activity changes typical in healthy aging and in AD. Additionally, we considered whether AD-accelerating effects of the copper fraction not bound to ceruloplasmin (also called “free” copper) are reflected in HFD fluctuations. The HFD measure showed an inverted U-shaped relationship with age in healthy people (R2 = .575, p < .001). Onset of HFD decline appeared around the age of 60, and was most evident in central-parietal regions. In this region, HFD decreased with aging stronger in the right than in the left hemisphere (p = .006). AD patients demonstrated reduced HFD compared to age- and education-matched healthy controls, especially in temporal-occipital regions. This was associated with decreasing cognitive status as assessed by mini-mental state examination, and with higher levels of non-ceruloplasmin copper. Taken together, our findings show that resting-state EEG complexity increases from youth to maturity and declines in healthy, aging individuals. In AD, brain activity complexity is further reduced in correlation with cognitive impairment. In addition, elevated levels of non-ceruloplasmin copper appear to accelerate the reduction of neural activity complexity. Overall, HDF appears to be a proper indicator for monitoring EEG-derived brain activity complexity in healthy and pathological aging. PMID:26872349

Recent studies have demonstrated developmental changes of functional brain networks derived from functional connectivity using graph theoretical analysis, which has been rapidly translated to studies of brain network organization. However, little is known about sex- and IQ-related differences in the topological organization of functional brain networks during development. In this study, resting-state fMRI (rs-fMRI) was used to map the functional brain networks in 51 healthy children. We then investigated the effects of age, sex, and IQ on economic small-world properties and regional nodal properties of the functional brain networks. At a global level of whole networks, we found significant age-related increases in the small-worldness and local efficiency, significant higher values of the global efficiency in boys compared with girls, and no significant IQ-related difference. Age-related increases in the regional nodal properties were found predominately in the frontal brain regions, whereas the parietal, temporal, and occipital brain regions showed age-related decreases. Significant sex-related differences in the regional nodal properties were found in various brain regions, primarily related to the default mode, language, and vision systems. Positive correlations between IQ and the regional nodal properties were found in several brain regions related to the attention system, whereas negative correlations were found in various brain regions primarily involved in the default mode, emotion, and language systems. Together, our findings of the network topology of the functional brain networks in healthy children and its relationship with age, sex, and IQ bring new insights into the understanding of brain maturation and cognitive development during childhood and adolescence.

Children with specific language impairment often present with multiple comorbidities, which may adversely affect both participation in play and academic performance, potentially impacting a child's health-related quality of life. This study 1) explored the suitability of the Pediatric Quality of Life Inventory™ Version 4.0 Generic Core Scales (PedsQL™) for use with a typically developing Australian control group, and 2) compared the health-related quality of life between a control group and Australian children with severe specific language impairment. Health-related quality of life data collected as part of a broader study of 43 children with severe specific language impairment (males = 35, age range 5-16, mean age = 8.79+/- 2.92) enrolled at a special school were used to explore previously unreported findings. Typically developing gender and age matched (+/- 3 months) peers were recruited from local schools. The PedsQL™ child self-report and proxy-report were individually or interviewer-administered to the control group as required, and then compared to the group with specific language impairment. The PedsQL™ was reliable and feasible for use with the control group (N = 43, males = 35, age range = 5-16 years, mean age = 8.74+/- 2.94 years). Control group performance was as expected as per the manual. Parents of the control group scored their children significantly higher than did the children themselves on all scales except the emotional functioning scale. Both the control group children and their parents scored themselves significantly higher on all scales, compared to children with severe specific language impairment and their parents. The PedsQL™ was suitable for use with the control group. Further, the recruitment of a control group provided additional clarity on the extent a severe specific language impairment impacts on an Australian child's perceived health-related quality of life, compared to the manual cut

The aim of this study was to compare ambulatory blood pressure monitoring (ABPM) parameters in offspring with at least one hypertensive parent (HP) to offspring with normotensive parents (NP) and to determine whether gender of parent or child might influence the association between parental hypertension and blood pressure (BP). Eighty-nine healthy children (mean age 11.1 +/- 3.9 years) with HP and 90 controls (mean age 10.5 +/- 3.1 years) with NP were recruited. Age, gender, and height did not differ between the two groups, whereas children of HP had higher weight, body mass index (BMI), and waist circumference compared with healthy controls. No difference was found in casual BP between the two groups. In contrast, during ABPM daytime and nighttime mean systolic and diastolic BP and mean arterial pressure (MAP) standard deviation scores (SDS) were significantly elevated in children with HP. The mean percentage of nocturnal BP decline (dipping) was not significantly different between the two groups. Children with hypertensive mothers had higher daytime systolic and MAP SDS than controls; no such difference was detected for children with hypertensive fathers. Daytime systolic and MAP SDS were significantly elevated in boys with HP compared with boys with NP but failed to be significant in girls. Multiple linear regression analysis showed that parental history of hypertension (B = 0.29) and BMI (B = 0.03) were independently correlated with increase of daytime MAP SDS. Early changes in ambulatory BP parameters were present in healthy children of HP. BP in HP offspring was influenced by the gender of the affected parent and the offspring.

This was to examine healthy children and adolescents treated under general anaesthesia (GA) and a matched control group not receiving GA to compare treatment and preventive care received prior to GA treatment. This retrospective cohort study included 71 healthy subjects and 213 age- and gender-matched control subjects. The treatment group had been consecutively referred from the Public Dental Health Service (PDS) in Stockholm to the Department of Paediatric Dentistry, Eastman Institute, Stockholm during 2006-2007. Data was extracted from the patient records at the PDS, including variables such as number of dental visits, treatment/prophylaxis prior to GA, number of missed and cancelled appointments, and number of decayed teeth. On average, the treatment group had significantly more decayed teeth (p < 0.001) than the control group. Furthermore, the treatment group had significantly more restorations (p < 0.01), had visited the dentist significantly more often (p < 0.001), and had undergone significantly more behaviour management treatment and preventive treatment (p < 0.001). In the treatment group 65% of the children and adolescents, had received no behaviour management treatment and 48%, no preventive treatment. In the Stockholm PDS, over half of the children and adolescents referred by general dentists to paediatric specialists had no behaviour management treatment and nearly half, no preventive treatment, despite receiving significantly more operative treatment compared with matched controls. General dentists should target high caries-risk patients for additional behaviour management and preventive care to reduce the need for treatment under GA.

To determine whether the relationship of gestational age (GA) with brain volumes and cognitive functions is linear or whether it follows a threshold model in preterm and term born children during school-age. We studied 106 children (M = 10 years 1 month, SD = 16 months; 40 females) enrolled in primary school: 57 were healthy very preterm children (10 children born 24-27 completed weeks' gestation (extremely preterm), 14 children born 28-29 completed weeks' gestation, 19 children born 30-31 completed weeks' gestation (very preterm), and 14 born 32 completed weeks' gestation (moderately preterm)) all born appropriate for GA (AGA) and 49 term-born children. Neuroimaging involved voxel-based morphometry with the statistical parametric mapping software. Cognitive functions were assessed with the WISC-IV. General Linear Models and multiple regressions were conducted controlling age, sex, and maternal education. Compared to groups of children born 30 completed weeks' gestation and later, children born <28 completed weeks' gestation had less gray matter volume (GMV) and white matter volume (WMV) and poorer cognitive functions including decreased full scale IQ, and processing speed. Differences in GMV partially mediated the relationship between GA and full scale IQ in preterm born children. In preterm children who are born AGA and without major complications GA is associated with brain volume and cognitive functions. In particular, decreased brain volume becomes evident in the extremely preterm group (born <28 completed weeks' gestation). In preterm children born 30 completed weeks' gestation and later the relationship of GA with brain volume and cognitive functions may be less strong as previously thought.

Developmental pattern of tibiofemoral angle in healthy north-east Indian children.

Physiological range of tibiofemoral angle (TFA) is poorly defined and may lead to unnecessary therapeutic interventions. Studies on TFA developmental pattern suggest that racial and ethnic differences are present; children in north-east India who have not yet been studied need to be evaluated. Cross-sectional study of clinical TFA, intermalleolar distance and intercondylar distance in 1020 healthy north-east Indian children aged from 2 to 18 years was done. Height, weight and body mass index were also recorded. At two years of age the mean TFA was valgus. The values reached a peak of 8.55° (standard deviation (SD) 1.01) valgus at seven years of age. The TFA then gradually stabilised to 3.18° (SD 1.18) valgus by 18 years of age. There was no significant difference in TFA between male and female patients. The present study is the largest and only the third such study on Indian children and the first on healthy northeast Indian children. By the end of two years most children had valgus angulation. This, along with the peak angulation observed, was similar to most of the other studies. The age at peak angulation and subsequent stabilisation of valgus angulation varied greatly among children of different origins, especially non-Indian children. Data can be used to identify children who require further follow-up/evaluation and can serve as guidelines during deformity correction and future studies. The development of TFA in this cohort is not different from other children of India but differs from children of other ethnic origins.

Position of the Academy of Nutrition and Dietetics: nutrition guidance for healthy children ages 2 to 11 years.

Ogata, Beth N; Hayes, Dayle

2014-08-01

It is the position of the Academy of Nutrition and Dietetics that children ages 2 to 11 years should achieve optimal physical and cognitive development, maintain healthy weights, enjoy food, and reduce the risk of chronic disease through appropriate eating habits and participation in regular physical activity. Rapid increases in the prevalence of childhood obesity during the 1980s and 1990s focused attention on young children's overconsumption of energy-dense, nutrient-poor foods and beverages and lack of physical activity. While recent data suggest a stabilization of obesity rates, several public health concerns remain. These include the most effective ways to promote healthy weights, the number of children living in food insecurity, the under-consumption of key nutrients, and the early development of diet-related risks for chronic diseases, such as cardiovascular disease, type 2 diabetes, cancer, obesity, and osteoporosis. This Position Paper reviews what children 2 to 11 years old in the United States are reportedly eating, explores trends in food and nutrient intakes, and examines the impact of federal nutrition programs on child nutrition. Current dietary recommendations and guidelines for physical activity are also discussed. The roles of parents and caregivers in influencing the development of life-long healthy eating behaviors are highlighted. The Academy of Nutrition and Dietetics works with other allied health and food industry professionals to translate dietary recommendations and guidelines into positive, practical health messages. Specific recommendations and sources of science-based nutrition messages to improve the nutritional well-being of children are provided for food and nutrition practitioners.

Adults and adolescents with major depressive disorder (MDD) show a blunted neural response to rewards. Depression has been validated in children as young as age 3; however, it remains unclear whether blunted response to reward is also a core feature of preschool-onset depression. If so, this would provide further validation for the continuity of the neural correlates of depression across the life span and would identify a potential target for treatment in young children. Fifty-three 4- to 7-year-old children with depression and 25 psychiatrically healthy 4- to 7-year-old children completed a simple guessing task in which points could be won or lost on each trial while event-related potentials (ERPs) were recorded. Psychiatric diagnosis was established using a preschool version of the Kiddie Schedule for Affective Disorders and Depression. Young children with depression showed a reduced differentiation between response to gains and losses, and this finding was driven by a blunted response to reward (i.e., the reward positivity [RewP]). These findings held even when controlling for co-occurring attention-deficit/hyperactivity disorder, oppositional defiant disorder, and generalized anxiety disorder. The RewP did not vary as a function of depression severity within the group with depression. Similar to adults and adolescents with depression, preschoolers with depression display reductions in responsivity to rewards as indexed by the RewP. These findings provide further evidence for continuity in the neural mechanisms associated with depression across the lifespan, and point to altered reward sensitivity as an early-emerging potential target for intervention in preschool-onset depression.

We examined linear and curvilinear correlations of gray matter volume and density in cortical and subcortical gray matter with age using magnetic resonance images (MRI) in a large number of healthy children. We applied voxel-based morphometry (VBM) and region-of-interest (ROI) analyses with the Akaike information criterion (AIC), which was used to determine the best-fit model by selecting which predictor terms should be included. We collected data on brain structural MRI in 291 healthy children aged 5-18 years. Structural MRI data were segmented and normalized using a custom template by applying the diffeomorphic anatomical registration using exponentiated lie algebra (DARTEL) procedure. Next, we analyzed the correlations of gray matter volume and density with age in VBM with AIC by estimating linear, quadratic, and cubic polynomial functions. Several regions such as the prefrontal cortex, the precentral gyrus, and cerebellum showed significant linear or curvilinear correlations between gray matter volume and age on an increasing trajectory, and between gray matter density and age on a decreasing trajectory in VBM and ROI analyses with AIC. Because the trajectory of gray matter volume and density with age suggests the progress of brain maturation, our results may contribute to clarifying brain maturation in healthy children from the viewpoint of brain structure.

Hermansen, R; Waksvik, H; Fønnebø, V

1991-03-01

The low risk of cancer in Seventh-Day Adventists (SDAs) has been suggested to be due to genetic selection. To investigate this claim we examined the sister chromatid exchange (SCE) frequency in peripheral blood lymphocytes in 16 SDA children in Tromsø, all aged 0.5-8 years and 16 controls matched for sex and age. In 12 of 16 pairs, the SDA children had a lower SCE frequency than the controls. The mean difference was 4.06 (95% confidence interval -17.02-8.89, P = 0.51). There was no sex difference, and no correlation between age and SCE frequency. The genetic starting point with regard to SCE frequency seems to be the same for SDA children and controls.

There are no population-based studies that have examined the association between vitamin D and type 1 diabetes mellitus (T1DM) and the role of lifestyle habits and dietary factors in young children in the Arabian Gulf and Middle East region. Little data on the intake of these nutrients in Mediterranean countries exist, and predictors of their suboptimal intake are not well defined. The objective of this study was to determine the association between vitamin D status and T1DM and assess the impact of lifestyle and dietary habits on hypovitaminosis D in the young population of the State of Qatar. A matched case-control study was carried out among T1DM children and healthy subjects <16 years of age at the pediatric endocrinology outpatient clinics of the Hamad General Hospital and the primary health care clinics center. The survey was conducted over a period from 6 August to 25 December 2007. The sample included 170 cases and 170 controls matched by age, gender and ethnicity. Face to face interviews were based on a questionnaire that included variables such as sociodemographic information, assessment of non-dietary covariates, assessment of dietary intake including vitamin D, type of feeding, clinical manifestations and laboratory investigations. Their health status was assessed by medical conditions, family history, body mass index, past or present clinical manifestations, serum 25(OH) vitamin D, calcium, alkaline phosphates, phosphorus, hemoglobin A1C, parathyroid hormone, magnesium and creatinine analysis. The study revealed that the incidence of severe vitamin D deficiency was considerably higher in T1DM (28.8%) compared with healthy children (17.1%). Although the mean serum level of vitamin D was significantly lower in T1DM children (15.80+/-9.23 ng/ml), compared with nondiabetic children (18.45+/-9.56 ng/ml), both groups belonged to the mild-moderate vitamin D deficiency category. A family history of vitamin D deficiency (35.3%; p=0.012) and diabetes mellitus

This study demonstrates that infants who are born prematurely and who have experienced at least 40days of intensive or special care have increased brain neuronal responses to noxious stimuli compared to healthy newborns at the same postmenstrual age. We have measured evoked potentials generated by noxious clinically-essential heel lances in infants born at term (8 infants; born 37-40weeks) and in infants born prematurely (7 infants; born 24-32weeks) who had reached the same postmenstrual age (mean age at time of heel lance 39.2+/-1.2weeks). These noxious-evoked potentials are clearly distinguishable from shorter latency potentials evoked by non-noxious tactile sensory stimulation. While the shorter latency touch potentials are not dependent on the age of the infant at birth, the noxious-evoked potentials are significantly larger in prematurely-born infants. This enhancement is not associated with specific brain lesions but reflects a functional change in pain processing in the brain that is likely to underlie previously reported changes in pain sensitivity in older ex-preterm children. Our ability to quantify and measure experience-dependent changes in infant cortical pain processing will allow us to develop a more rational approach to pain management in neonatal intensive care.

The 'Healthy Dads, Healthy Kids' community effectiveness trial: study protocol of a community-based healthy lifestyle program for fathers and their children

PubMed Central

2011-01-01

Background The 'Healthy Dads, Healthy Kids' program was designed to help overweight fathers lose weight and positively influence the health behaviors of their children. The aim of the current study was to evaluate the previously established program in a community setting, in a large effectiveness trial. Methods/Design The Healthy Dads, Healthy Kids community trial consists of three stages: (i) Stage 1 - program refinement and resource development (ii) Stage 2 - community randomized controlled trial (iii) Stage 3 - community effectiveness trial. The program will be evaluated in five Local Government Areas in the Hunter Valley Region of NSW, Australia. For the community randomized controlled trial, 50 overweight/obese men (aged 18-65 years) from one Local Government Area with a child aged between 5-12 years of age will be recruited. Families will be randomized to either the program or a 6-month wait-list control group. Fathers and their children will be assessed at baseline, post-intervention (3-months) and 6-months. Inclusion criteria are: body mass index 25-40 kg/m2; no participation in other weight loss programs during the study; pass a health-screening questionnaire; and access to a computer with Internet facilities. In the community trial, the program will be evaluated using a non-randomized, prospective design in five Local Government Areas. The exclusion criteria is body mass index < 25 kg/m2 or lack of doctor's approval. Measures will be collected at baseline, 3-, 6- and 12-months. The program involves fathers attending seven face-to-face group sessions (three with children) over 3-months. Measures: The primary outcome is fathers' weight. Secondary outcomes for both fathers and children include: waist circumference, blood pressure, resting heart rate, physical activity, sedentary behaviors and dietary intake. Father-only measures include portion size, alcohol consumption, parenting for physical activity and nutrition and parental engagement. Process

Within the obesity literature, focus is put on the link between weight status and gross motor skills. However, research on fine motor skills in the obese (OB) childhood population is limited. Therefore, the present study focused on possible weight related differences in gross as well as fine motor skill tasks. Thirty-four OB children (12 ♀ and 22 ♂, aged 7-13 years) were recruited prior to participating in a multidisciplinary treatment program at the Zeepreventorium (De Haan, Belgium). Additionally, a control group of 34 age and gender-matched healthy-weight (HW) children was included in the study. Anthropometric measures were recorded and gross and fine motor skills were assessed using the Bruininks-Oseretsky Test of Motor Proficiency, second edition (BOT-2). Results were analyzed by independent samples t-tests, multivariate analysis of variance, and a chi-squared test. Being OB was detrimental for all subtests evaluating gross motor skill performance (i.e., upper-limb coordination, bilateral coordination, balance, running speed and agility, and strength). Furthermore, OB children performed worse in fine motor precision and a manual dexterity task, when compared to their HW peers. No group differences existed for the fine motor integration task. Our study provides evidence that lower motor competence in OB children is not limited to gross motor skills alone; OB children are also affected by fine motor skill problems. Further investigation is warranted to provide possible explanations for these differences. It is tentatively suggested that OB children experience difficulties with the integration and processing of sensory information. Future research is needed to explore whether this assumption is correct and what the underlying mechanism(s) could be. Copyright © 2013 Elsevier Ltd. All rights reserved.

2011-10-01

Caregivers often struggle with food neophobia on the part of young children. This study examined whether labeling novel healthy foods with fun names would increase children's willingness to try those foods and encourage them to eat more of those foods in a child care setting. Thirty-nine toddler and preschool age children (mean age = 3.9 years) were served each of three foods twice, once labeled with a fun name and once with a healthy name. Percentage of the food consumed by each child was recorded. Overall, children ate a greater percentage of the target foods when they were labeled with fun names. Also, a larger percentage of the children tasted the foods when they were labeled with fun names. This simple strategy could be effective for increasing consumption of healthy foods among young children.

Associations between diet, physical activity, parenting, and acculturation among Chinese-American children are understudied. Parents/caregivers of children attending child-care programs in Boston Chinatown completed a self-administered survey on demographics, child's diet, physical activities, anthropometrics, and parenting practices. Associations were evaluated in multivariable regression analysis, stratified by survey language preference, a proxy for acculturation. Responding Asian families = 132; 86.4% were immigrants; 75.8% completed the Chinese-version survey. Children (mean ± SD: 4.9 ± 1.1 years) did not eat vegetables (31.8%), or play actively outside (45.4%) daily, 64.8% watched television/screens daily; 32.6% were overweight/obese (based on parent report). Parenting practices associated with obesity were apparent. Although healthy-living behavioral outcomes were less prevalent among less acculturated parents; multivariable adjustment attenuated the observed significant differences. Findings suggest opportunities for improvement in study children's diet and healthy-living behaviors, and underscore the need for further research on acculturation, and parenting styles in this population.

In a previous study we demonstrated children with Benign Rolandic Epilepsy have normal intelligence and language ability. However, difficulties in verbal and visual memory and aspects of phonological awareness were found compared to normative data. To address the methodological limitations related to the use of normative data, we compared the same cohort of children with Benign Rolandic Epilepsy to a matched control group. Controls (n=40) matched on age and gender to the Benign Rolandic Epilepsy cohort underwent neuropsychological assessment. The life functioning of the control group was assessed using a modified version of the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE). The study confirmed the previous findings of memory and phonological awareness difficulties. In addition, the children with Benign Rolandic Epilepsy had significantly lower IQ scores than the matched control group. Paired sample t-tests showed that on 8 of 11 QOLCE scales, children with Benign Rolandic Epilepsy were rated by parents as having poorer life functioning compared to matched controls, including lower parental ratings on the subscales of memory and language. Benign Rolandic Epilepsy has an excellent seizure prognosis, but this study further emphasizes potential cognitive difficulties. Using an age and gender matched control group, the previous findings of memory and phonological awareness difficulties were validated. These problems in cognition were also identified by parents of children with Benign Rolandic Epilepsy as problematic and impacting upon the child's quality of life.

Catching-up: Children with developmental coordination disorder compared to healthy children before and after sensorimotor therapy

PubMed Central

2017-01-01

The aims of the present study were to (a) compare healthy children in terms of sensorimotor maturity to untreated children diagnosed with developmental coordination disorder (DCD) and (b) compare healthy children to diagnosed children following completed treatment with sensorimotor therapy. Participants were 298 children, 196 boys and 102 girls, distributed into a Norm group of healthy children (n = 99) and a group of children diagnosed with DCD (n = 199) with a total mean age of 8.77 years (SD = 2.88). Participants in both groups were assessed on instruments aimed to detect sensorimotor deviations. The children in the DCD group completed, during on average 36 months, sensorimotor therapy which comprised stereotypical fetal- and infant movements, vestibular stimulation, tactile stimulation, auditory stimulation, complementary play exercises, gross motor milestones, and sports-related gross motor skills. At the final visit a full assessment was once more performed. Results showed that the Norm group performed better on all sensorimotor tests as compared to the untreated children from the DCD group, with the exception of an audiometric test where both groups performed at the same level. Girls performed better on tests assessing proprioceptive and balance abilities. Results also showed, after controls for natural maturing effects, that the children from the DCD group after sensorimotor therapy did catch up with the healthy children. The concept of “catching-up” is used within developmental medicine but has not earlier been documented with regard to children and youth in connection with DCD. PMID:29020061

To study the reference ranges of six sex hormones, i.e., luteinizing hormone, follicle-stimulating hormone, progesterone, prolactin, estradiol, and testosterone, for healthy children aged 0-18 years in Shenzhen, China. Stratified cluster sampling was performed to select 2 178 healthy children aged 0-18 years in the districts of Futian, Luohu, Nanshan, Bao'an, and Longgang in Shenzhen between September 2015 and September 2016. There were 1 219 boys and 959 girls, including 81 neonates, 335 infants, 346 young children, 469 preschool children, 419 school-aged children, and 528 adolescents. The American Beckman DXI800 chemiluminescence meter was used to measure the levels of luteinizing hormone, follicle-stimulating hormone, progesterone, prolactin, estradiol, and testosterone. There were significant differences in the levels of luteinizing hormone, follicle-stimulating hormone, progesterone, prolactin, estradiol, and testosterone between different age groups (P<0.05). There were also significant differences in the levels of these sex hormones between boys and girls in the same age group (P<0.05). The reference ranges of six sex hormones were established for healthy children aged 0-18 years in Shenzhen based on the levels of these hormones in different age groups. There are significant differences in sex hormones between different age groups or sex groups. The reference ranges of six sex hormones established for different sexes or ages have great significance in the diagnosis and treatment of endocrine diseases in children.

The aim of the study was to determine whether lifelong football training may improve cardiovascular function, physical fitness, and body composition. Our subjects were 17 male veteran football players (VPG; 68.1 ± 2.1 years) and 26 healthy age-matched untrained men who served as a control group (CG; 68.2 ± 3.2 years). Examinations included measurements of cardiac function, microvascular endothelial function [reactive hyperemic index (RHI)], maximum oxygen uptake (VO2max), and body composition. In VPG, left ventricular (LV) end-diastolic volume was 20% larger (P < 0.01) and LV ejection fraction was higher (P < 0.001). Tissue Doppler imaging revealed an augmented LV longitudinal displacement, i.e., LV shortening of 21% (P < 0.001) and longitudinal 2D strain was 12% higher (P < 0.05), in VPG. In VPG, resting heart rate was lower (6 bpm, P < 0.05), and VO2max was higher (18%, P < 0.05). In addition, RHI was 21% higher (P < 0.05) in VPG. VPG also had lower body mass index (P < 0.05), body fat percentage, total body fat mass, android fat percentage, and gynoid fat percentage (all P < 0.01). Lifelong participation in football training is associated with better LV systolic function, physical fitness, microvascular function, and a healthier body composition. Overall, VPG have better cardiovascular function compared with CG, which may reduce their cardiovascular morbidity and mortality. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Since 2009, quick-service restaurant chains, or fast-food companies, have agreed to depict healthy foods in their advertising targeted at children. To determine how children interpreted depictions of milk and apples in television advertisements for children's meals by McDonald's and Burger King (BK) restaurants. Descriptive qualitative study in a rural pediatric practice setting in Northern New England. A convenience sample of 99 children (age range, 3-7 years) was shown depictions of healthy foods in fast-food advertisements that aired from July 1, 2010, through June 30, 2011. The images from McDonald's and BK showed milk and apples. Children were asked what they saw and not prompted to respond specifically to any aspect of the images. Two still images drawn from advertisements for healthy meals at McDonald's and BK. Children's responses were independently content coded to food category by 2 researchers. Among the 99 children participating, only 51 (52%) and 69 (70%) correctly identified milk from the McDonald's and BK images, respectively, with a significantly greater percentage correct (P = .02 for both) among older children. The children's recall of apples was significantly different by restaurant, with 79 (80%) mentioning apples when describing the McDonald's image and only 10 (10%) for the BK image (P < .001). The percentage correct was not associated with age in either case. Conversely, although french fries were not featured in either image, 80 children (81%) recalled french fries after viewing the BK advertisement. Of the 4 healthy food images, only depiction of apples by McDonald's was communicated adequately to the target audience. Representations of milk were inadequately communicated to preliterate children. Televised depictions of apple slices by BK misled the children in this study, although no action was taken by government or self-regulatory bodies.

Nocturnal enuresis is a common developmental disorder in children, and primary monosymptomatic nocturnal enuresis (PMNE) is the dominant subtype. This study investigated brain functional abnormalities that are specifically related to working memory in children with PMNE using function magnetic resonance imaging (fMRI) in combination with an n-back task. Twenty children with PMNE and 20 healthy children, group-matched for age and sex, participated in this experiment. Several brain regions exhibited reduced activation during the n-back task in children with PMNE, including the right precentral gyrus and the right inferior parietal lobule extending to the postcentral gyrus. Children with PMNE exhibited decreased cerebral activation in the task-positive network, increased task-related cerebral deactivation during a working memory task, and longer response times. Patients exhibited different brain response patterns to different levels of working memory and tended to compensate by greater default mode network deactivation to sustain normal working memory function. Our results suggest that children with PMNE have potential working memory dysfunction.

The study was conducted at the King Saud University College of Dentistry Interns Clinic at Darraiyah University Campus, Riyadh, Saudi Arabia, from October to December 2013, and comprised a sample of 6-to-11-year-old children and their parents. A questionnaire was used to record height/weight data, history of body weight counselling and parental opinion regarding healthy weight screening and counselling. SPSS 17 was used for data analysis. Of the 61 children, 35(57.4%) were boys and 26(42.6%) were girls. The overall mean age was 7.9±1.7 years (range: 6-11 years). Besides, 40(65.6%) children were accompanied by their fathers and 21(34.4%) by their mothers. Overall 13(21.3%) children were overweight and 7(11.5%) obese. Moreover, 54(88.5%) parents found the healthy weight screening and counselling for their children valuable, whereas 46(75.4%) endorsed the screening/counselling during the dental visit of their children. Most parents found healthy weight screening and counselling to be valuable, and endorsed its administration during dental visits for their children.

The aim of this study was to evaluate the effectiveness of the administration of the 7-valent pneumococcal conjugate vaccine in a region with an intermediate vaccination coverage. A matched case-control study was carried out in children aged 7-59 months with invasive pneumococcal disease (IPD) admitted to two university hospitals in Catalonia. Three controls matched for hospital, age, sex, date of hospitalization and underlying disease were selected for each case. Information on the vaccination status of cases and controls was obtained from the vaccination card, the child's health card, the hospital medical record or the vaccination register of the primary healthcare center where the child was attended for non-severe conditions. A conditional logistic regression analysis was made to control for the effect of possible confounding variables. The adjusted vaccination effectiveness of the complete vaccination schedule (3 doses at 2, 4 and 6 months and a fourth dose at 15 months, 2 doses at least two months apart in children aged 12-23 months or a single dose in children aged >24 months) in preventing IPD caused by vaccine serotypes was 93.7% (95% CI 51.8-99.2). It was not effective in preventing cases caused by non-vaccine serotypes. The results of this study carried out in a population with intermediate vaccination coverage confirm those of other observational studies showing high levels of effectiveness of routine 7-valent pneumococcal conjugate vaccination.

Obesity prevalence among children is high and knowledge on cognitive factors that contribute to children's reactivity to the "obesogenic" food environment could help to design effective treatment and prevention campaigns. Empirical studies in adults suggest that attention bias for food could be a risk factor for overeating. Accordingly, the current study tested if children with obesity have an elevated attention bias for food when compared to healthy-weight children. Another aim was to explore whether attention biases for food predicted weight-change after 3 and 6 months in obese children. Obese children (n = 34) were recruited from an intervention program and tested prior to the start of this intervention. Healthy-weight children (n = 36) were recruited from local schools. First, attention biases for food were compared between children with obesity (n = 30) and matched healthy-weight children (n = 30). Second, regression analyses were conducted to test if food-related attention biases predicted weight changes after 3 and 6 months in children with obesity following a weight loss lifestyle intervention. Results showed that obese children did not differ from healthy-weight children in their attention bias to food. Yet automatically directing attention toward food (i.e., initial orientation bias) was related to a reduced weight loss (R² = .14, p = .032) after 6 months in children with obesity. High palatable food is a salient stimulus for all children, irrespective of their weight status. However, automatically directing attention to food cues might facilitate further weight gain in children with obesity. (c) 2015 APA, all rights reserved).

Positive peer relationships are essential in healthy development. The prevalence of peer-relationship problems in children after acquired brain injury (ABI) has yet to be explored, although ABI does inevitably impact upon peer interactions. We aimed to explore how peer-relationships and emotional distress after ABI may differ from the levels reported by healthy children or mental health controls. Parents of 214 children (137 "healthy" children, 27 children using mental health services and 40 children with ABI) aged 9-15 years participated. A questionnaire measure of peer-relationship functioning and emotional distress was completed. Children with ABI experienced a greater degree of peer-relationship difficulties and emotional distress than healthy controls. No difference was found in reported peer relationship difficulties or emotional distress between ABI children and the children accessing mental health services. We conclude that emotional distress and co-occurring peer-relationship difficulties are as prevalent in a population of children after ABI as may be expected in a population of children under the care of mental health services, yet, unlike the latter group, appropriate intervention services are not commonly available. Interventions that aim to enhance peer relationships after childhood ABI may provide an essential resource to the benefit of outcome.

2016-01-01

Research on the relationship between aspects of language development and Theory of Mind (ToM) in children with language impairments suggests that children with language impairment show a delay in ToM development. This study aimed to examine the relationships of the syntactic, semantic, and pragmatic skills with ToM in school-age children. Twenty children with Specific Language Impairment (SLI) aged 9-12 years and two control groups, one matched for chronological age (CA) and one for language ability (LA) (aged 8-10 years) were compared on a set of language tasks tapping syntactic, semantic, and pragmatic skills and on an advanced test of ToM. Results showed that children with SLI performed poorly on the ToM task compared to the CA matches. Also, analysis showed that language skills and ToM are related and that syntactic and pragmatic abilities contributed significantly to the prediction of ToM performance in the SLI group. It is concluded that the syntax/pragmatic aspects of the language impact on ToM understanding in children with SLI. Copyright © 2016 Elsevier Inc. All rights reserved.

Away-from-home eating is an important dietary behavior with implications on diet quality. Thus, it is an important behavior to target to prevent and control childhood obesity and other chronic health conditions. Numerous studies have been conducted to improve children's dietary intake at home, in early care and education, and in schools; however, few studies have sought to modify the restaurant food environment for children. This study adds to this body of research by describing the development and launch of an innovative intervention to promote sales of healthy children's menu items in independent restaurants in Southern California, United States. This is a cluster randomized trial with eight pair-matched restaurants in San Diego, California. Restaurants were randomized to a menu-only versus menu-plus intervention condition. The menu-only intervention condition involves manager/owner collaboration on the addition of pre-determined healthy children's menu items and kitchen manager/owner collaboration to prepare and plate these items and train kitchen staff. The menu-plus intervention condition involves more extensive manager/owner collaboration and kitchen staff training to select, prepare, and plate new healthy children's menu items, and a healthy children's menu campaign that includes marketing materials and server training to promote the items. The primary outcome is sales of healthy children's menu items over an 18-week period. In addition, dining parties consisting of adults with children under 18 years of age are being observed unobtrusively while ordering and then interviewed throughout the 18-week study period to determine the impact of the intervention on ordering behaviors. Manager/owner interviews and restaurant audits provide additional evidence of impact on customers, employees, and the restaurant environment. Our process evaluation assesses dose delivered, dose received, and intervention fidelity. Successful recruitment of the restaurants has been

A forced-choice reaction-time (RT) task was used to examine voluntary visual orienting among children and adolescents with trisomy 21 Down syndrome and typically developing children matched at an MA of approximately 5.6 years, an age when the development of orienting abilities reaches optimal adult-like efficiency. Both groups displayed faster reaction times (RTs) when the target location was cued correctly than when cued incorrectly under both short and long SOA conditions, indicating intact orienting among children with Down syndrome. This finding is further evidence that the efficiency of many of the primary components of attention among persons with Down syndrome is consistent with their developmental level.

States compel children to attend school; in fact, 98% of all school-age children attend schools--irrespective of conditions. Yet the environmental conditions of decayed facilities or facilities close to hazards can damage children's health and ability to learn. At the same time, it is well documented that healthy school facilities can help…

Parents of children with autism spectrum disorder (ASD) frequently report that their children have selective eating behaviors and refuse many foods, which could result in inadequate nutrient intake. This preliminary cross-sectional descriptive study investigated dietary intake and parents' reported perception of food behaviors of 20 3- to 5-year-old children with ASD. Twenty typically developing children matched for sex, age, and ethnicity were also studied as a case-control comparison. Nutrient intake determined from 3-day food records was adjusted for day-to-day variation to determine the estimate of usual intake distribution for the two groups. This distribution was compared with the Estimated Average Requirement or Adequate Intake recommendations. The reported food behaviors and use of vitamin or mineral supplements were compared for matched pairs using the exact McNemar test. Nutrient intake was similar for both groups of children, with the majority of children consuming more than the recommended amounts for most nutrients. Nutrients least likely to be consumed in recommended amounts were vitamin A, vitamin E, fiber, and calcium. Children with ASD were more likely to consume vitamin/mineral supplements than typically developing children. Compared with parents of typically developing children, parents of children with ASD were more likely to report that their children were picky eaters and resisted trying new foods, and they were less likely to describe their children as healthy eaters or that they eat a variety of foods. Despite the similar and generally adequate nutrient intake for the 40 children in this study, parents of children with ASD had more negative perceptions of their children's dietary behaviors.

The combination of peripheral neuropathy and other treatment-associated side effects is likely related to an increased incidence of falls in cancer survivors. The purpose of this study was to quantify differences in postural stability between healthy age-matched controls and cancer survivors. Quiet standing under four conditions (eyes open/closed, rigid/compliant surface) was assessed in 34 cancer survivors (2 males, 32 females; age: 54(13) yrs., height: 1.62(0.07) m; mass: 78.5(19.5) kg) and 34 age-matched controls (5 males, 29 females; age: 54(15) yrs.; height: 1.62(0.08) m; mass: 72.8(21.1) kg). Center of pressure data were collected for 30s and the trajectories were analyzed (100Hz). Three-factor (group*surface*vision) mixed model MANOVAs with repeated measures were used to determine the effect of vision and surface on postural steadiness between groups. Cancer survivors exhibited larger mediolateral root-mean square distance and velocity of the center of pressure, as well as increased 95% confidence ellipse area (P<0.01) when compared with their age-matched counterparts. For example, when removing visual input, cancer survivors had an average increase in 95% confidence ellipse area of 91.8mm 2 while standing on a rigid surface compared to a 68.6mm 2 increase for the control group. No frequency-based center of pressure measures differed between groups. Cancer survivors exhibit decreased postural steadiness when compared with age-matched controls. For cancer survivors undergoing rehabilitation focused on existing balance deficits, a small subset of the center of pressure measures presented here can be used to track progress throughout the intervention and potentially mitigate fall risk.

To assess the level of circulating endothelial progenitor cells (CEPC) in cycling women compared with men and menopausal women. Controlled clinical study. Healthy, nonsmoking volunteers. Twelve women, aged 18-40 years, with regular menstrual cycles, 12 menopausal women, and two groups of 12 age-matched men were recruited. Women did not receive any hormone therapy. Collection of 20 mL of peripheral blood. The number of CEPC, defined as (Lin-/7AAD-/CD34+/CD133+/KDR+) cells per 10(6) mononuclear cells (MNC), was measured by flow cytometry. The number of CEPC was significantly higher in cycling women than in age-matched men and menopausal women (26.5 per 10(6) MNC vs. 10.5 per 10(6) MNC vs. 10 per 10(6) MNC, respectively). The number of CEPC was similar in menopausal women, age-matched, and young men. The number of CEPC is influenced by an age-gender interaction. This phenomenon may explain in part the better vascular repair and relative cardiovascular protection in younger women as compared with age-matched men.

Australian data indicate that 63% of children participated in sport in 2009, a 4% increase since 2000. Children's high participation in sport, and the association between sport and health, means that these settings provide an opportunity to promote other aspects of health, such as healthy eating, to children. This study aimed to determine healthy eating practices and policies at children's sports clubs. Sports clubs (n=108) for the nine most popular sports for children aged 5 to 14 were randomly sampled from three large geographical areas across one state and one territory in Australia. A purpose-designed telephone questionnaire for sports club officials was developed to determine the food and beverages sold, provided and promoted at sports clubs and the availability of healthy-eating policies. The most frequently sold item at canteens was water, followed by sports drinks, chocolate/confectionery and soft drink. Only 20% of canteens promoted healthy food. Thirty-nine per cent of clubs made recommendations on the food and beverages to be consumed during sport, mostly relating to water consumption. The majority (76%) engaged in fundraising; many in collaboration with chocolate/confectionery companies. Only three clubs had a written policy on healthy eating. Addressing the low uptake of healthy eating policies would be a useful strategy to improve the healthiness of sports clubs. Policies could seek to reduce the availability and promotion of unhealthy food and beverages through canteens, vending machines and fundraising. © 2010 The Authors.

Brazil is a country with great climatic, socioeconomic, and cultural differences that does not yet have a reference value for the 6-min walk test (6MWT) in healthy children. To avoid misinterpretation, the use of equations to predict the maximum walk distance should be established in each country. We sought to establish reference values and to develop an equation to predict the 6-min walk distance for healthy children in Brazil. This is a cross-sectional multi-center study that included 1,496 healthy children, aged 7 to 12 y, assessed across 11 research sites in all regions of Brazil, and recruited from public and private schools in their respective regions. Each child was assessed for weight and height. Walk distance was our main outcome. An open-source software environment for statistical computing was used for statistical analysis. We observed a higher average distance walked by boys (531.1 m) than by girls (506.2 m), with a difference of 24.9 m ( P < .001). We established 6MWT reference values for boys with the following equation: Distance = (16.86 × age) + (1.89 × Δ heart rate) - (0.80 × weight) + (336.91 × R1) + (360.91 × R2). For girls the equation is as follows: Distance = (13.54 × age) + (1.62 × Δ heart rate) - (1.28 × weight) + (352.33 × R1) + (394.81 × R2). Reference values were established for the 6MWT in healthy children aged 7-12 y in Brazil. Copyright © 2018 by Daedalus Enterprises.

Multisensory information boosts numerical matching abilities in young children.

PubMed

Jordan, Kerry E; Baker, Joseph

2011-03-01

This study presents the first evidence that preschool children perform more accurately in a numerical matching task when given multisensory rather than unisensory information about number. Three- to 5-year-old children learned to play a numerical matching game on a touchscreen computer, which asked them to match a sample numerosity with a numerically equivalent choice numerosity. Samples consisted of a series of visual squares on some trials, a series of auditory tones on other trials, and synchronized squares and tones on still other trials. Children performed at chance on this matching task when provided with either type of unisensory sample, but improved significantly when provided with multisensory samples. There was no speed–accuracy tradeoff between unisensory and multisensory trial types. Thus, these findings suggest that intersensory redundancy may improve young children’s abilities to match numerosities.

Learning how to make healthy eating decisions, (i.e., resisting unhealthy foods and consuming healthy foods), enhances physical development and reduces health risks in children. Although healthy eating decisions are known to be challenging for children, the mechanisms of children's food choice processes are not fully understood. The present study recorded mouse movement trajectories while eighteen children aged 8-13 years were choosing between eating and rejecting foods. Children were inclined to choose to eat rather than to reject foods, and preferred unhealthy foods over healthy foods, implying that rejecting unhealthy foods could be a demanding choice. When children rejected unhealthy foods, mouse trajectories were characterized by large curvature toward an eating choice in the beginning, late decision shifting time toward a rejecting choice, and slowed response times. These results suggested that children exercised greater cognitive efforts with longer decision times to resist unhealthy foods, providing evidence that children require dietary self-control to make healthy eating-decisions by resisting the temptation of unhealthy foods. Developmentally, older children attempted to exercise greater cognitive efforts for consuming healthy foods than younger children, suggesting that development of dietary self-control contributes to healthy eating-decisions. The study also documents that healthy weight children with higher BMIs were more likely to choose to reject healthy foods. Overall, findings have important implications for how children make healthy eating choices and the role of dietary self-control in eating decisions. Published by Elsevier Ltd.

Hypercapnic evaluation of vascular reactivity in healthy aging and acute stroke via functional MRI.

Raut, Ryan V; Nair, Veena A; Sattin, Justin A; Prabhakaran, Vivek

2016-01-01

Functional MRI (fMRI) is well-established for the study of brain function in healthy populations, although its clinical application has proven more challenging. Specifically, cerebrovascular reactivity (CVR), which allows the assessment of the vascular response that serves as the basis for fMRI, has been shown to be reduced in healthy aging as well as in a range of diseases, including chronic stroke. However, the timing of when this occurs relative to the stroke event is unclear. We used a breath-hold fMRI task to evaluate CVR across gray matter in a group of acute stroke patients (< 10 days from stroke; N = 22) to address this question. These estimates were compared with those from both age-matched (N = 22) and younger (N = 22) healthy controls. As expected, young controls had the greatest mean CVR, as indicated by magnitude and extent of fMRI activation; however, stroke patients did not differ from age-matched controls. Moreover, the ipsilesional and contralesional hemispheres of stroke patients did not differ with respect to any of these measures. These findings suggest that fMRI remains a valid tool within the first few days of a stroke, particularly for group fMRI studies in which findings are compared with healthy subjects of similar age. However, given the relatively high variability in CVR observed in our stroke sample, caution is warranted when interpreting fMRI data from individual patients or a small cohort. We conclude that a breath-hold task can be a useful addition to functional imaging protocols for stroke patients.

Quality of life in healthy children and in children with tension headaches--a comparative analysis.

Talarska, D

2005-01-01

The aim of this study was the assessment of the quality of life of children and adolescents with tension headaches in comparison with healthy peers. The study was conducted on 135 middle school and high school students in Poznań and on 86 children with tension headaches, that were treated in the out-patient clinic of The Chair and Clinic of Development Age Neurology of Karol Marcinkowski University of Medical Sciences in Poznań. The research tool for both groups was Pediatric Quality of Life Inventory, version 4.0 (PedsQL 4.0) questionnaire. In the analysed groups dominated 14- and 16-year-old children. Among children with tension headaches, the ailments usually appeared once or twice a week in 39 (45%) of them. With the use of the PedsQL 4.0 questionnaire the following fields of activity were analyzed: biological, emotional, social functioning and mood. The biggest discrepancies between the group of healthy children and those with headaches were noted in the field of emotional functioning and mood. Adolescents with tension headaches more frequently reported the feeling of fear and sleep disorders in comparison to healthy students. Children with headaches look at the future in a more pessimistic way and are less satisfied with their lives.

Objective: To obtain reference values for FEV1, FVC, FEV1% and PEFR among children aged 8-14 years in south Gujarat region of India. Materials and Methods: This cross-sectional study was conducted among 655 normal healthy school children (408 boys and 247 girls) of Surat city aged 8 to 14 years studying in V to VII standard during November 2007 to April 2008. Height, weight, body surface area were measured. All included children were tested in a sitting position with the head straight after taking written consent from parents. Spirometry was done using the spirometer “Spirolab II” MIR 010. Spirometer used in the study facilitates the total valuation of lung function including forced vital capacity (FVC), forced expiratory volume in one second (FEV1), forced expiratory volume ratio in one second (FEV1%) and peak expiratory flow rate (PEFR). Results: FVC, FEV1 and PEFR were found to be statistically significant in the study groups. For FVC and FEV1, highest correlation was found with age in girls and height in boys. For FEV1%, significant negative correlation was found with age and height in both sexes, but positive correlation was found with surface area. Similarly, PEFR showed highest correlation with surface area in boys and girls. Conclusion: Variables such as FVC, FEV1 and PEFR show good positive correlation with height, age and body surface area in both sexes. There is a need to have regional values for the prediction of normal spirometric parameters in a country like India with considerable diversity. PMID:20931033

To determine if there is an association between longer breast-feeding duration and dental caries in healthy urban children. We conducted a cross-sectional study of urban children aged 1 to 6 years recruited through The Applied Research Group for Kids (TARGet Kids!) practice-based research network between September 2011 and August 2013. The main outcome measure was parental report of dental caries. The adjusted predicted probability of dental caries was 7%, 8%, 11%, and 16% with total duration of breast-feeding duration of 12, 18, 24, and 36 months, respectively. In the adjusted logistic regression analyses, relative to breast-feeding 0 to 5 months, the odds of dental caries with total breast-feeding duration >24 months was 2.75 (95% confidence interval 1.61-4.72). Among healthy urban children, longer breast-feeding duration was associated with higher odds of dental caries. These findings support heightened awareness and enhanced anticipatory guidance for preventive dental care, particularly among children who breast-feed beyond 2 years of age.

Despite national attention to the childhood obesity epidemic, there are few US-based studies that directly ask children--especially children from low-income families and from multiple racial/ethnic groups--why they do or do not engage in healthy eating behaviors. The purpose of this study was to identify motivators of and barriers to healthy eating behaviors, as reported by black, Hispanic, and white children from low-income families. Six gender- and race/ethnicity-concordant focus groups were conducted with 37 children who were aged 9 to 12 years and from families with an annual household income of $40000 or less. Multiple strategies were used to employ a culturally sensitive approach to both data collection and data analysis (eg, a team of culturally diverse researchers utilized inductive qualitative analysis to analyze focus group transcripts). The motivators of and barriers to healthy eating behaviors most commonly reported across the 6 focus groups included social influence, taste, issues of availability, weight concerns, and the desire to be healthy. A variety of less commonly reported motivators and barriers were also discussed. Findings were generally similar across gender and race/ethnicity. Children in this age range can indeed identify a variety of motivators and barriers that influence their engagement in healthy eating behaviors. Interventions targeting obesity and eating behaviors should include an assessment of children's own perceived motivators of and barriers to healthy eating.

Endothelium-dependent control of cerebrovascular functions through age: exercise for healthy cerebrovascular aging.

PubMed

Bolduc, Virginie; Thorin-Trescases, Nathalie; Thorin, Eric

2013-09-01

Cognitive performances are tightly associated with the maximal aerobic exercise capacity, both of which decline with age. The benefits on mental health of regular exercise, which slows the age-dependent decline in maximal aerobic exercise capacity, have been established for centuries. In addition, the maintenance of an optimal cerebrovascular endothelial function through regular exercise, part of a healthy lifestyle, emerges as one of the key and primary elements of successful brain aging. Physical exercise requires the activation of specific brain areas that trigger a local increase in cerebral blood flow to match neuronal metabolic needs. In this review, we propose three ways by which exercise could maintain the cerebrovascular endothelial function, a premise to a healthy cerebrovascular function and an optimal regulation of cerebral blood flow. First, exercise increases blood flow locally and increases shear stress temporarily, a known stimulus for endothelial cell maintenance of Akt-dependent expression of endothelial nitric oxide synthase, nitric oxide generation, and the expression of antioxidant defenses. Second, the rise in circulating catecholamines during exercise not only facilitates adequate blood and nutrient delivery by stimulating heart function and mobilizing energy supplies but also enhances endothelial repair mechanisms and angiogenesis. Third, in the long term, regular exercise sustains a low resting heart rate that reduces the mechanical stress imposed to the endothelium of cerebral arteries by the cardiac cycle. Any chronic variation from a healthy environment will perturb metabolism and thus hasten endothelial damage, favoring hypoperfusion and neuronal stress.

To assess thiamine and related metabolite status by analysis of plasma and urine in autistic children and healthy controls, correlations to clinical characteristics and link to plasma protein markers of oxidative damage. 27 children with autism (21 males and 6 females) and 21 (15 males and 6 females) age-matched healthy control children were recruited. The concentration of thiamine and related phosphorylated metabolites in plasma and urine and plasma protein content of dityrosine, N-formylkynurenine and 3-nitrotyrosine was determined. Plasma thiamine and thiamine monophosphate concentrations were similar in both study groups (median [lower-upper quartile]): autistic children - 6.60 nM (4.48-8.91) and 7.00 nM (5.51-8.55), and healthy controls - 6.82 nM (4.47-7.02) and 6.82 nM (5.84-8.91), respectively. Thiamine pyrophosphate (TPP) was decreased 24% in autistic children compared to healthy controls: 6.82 nM (5.81-8.52) versus 9.00 nM (8.41-10.71), p < .01. Urinary excretion of thiamine and fractional renal clearance of thiamine did not change between the groups. No correlation was observed between clinical markers and the plasma and urine thiamine concentration. Plasma protein dityrosine content was increased 88% in ASD. Other oxidative markers were unchanged. Autistic children had normal plasma and urinary thiamine levels whereas plasma TPP concentration was decreased. The latter may be linked to abnormal tissue handling and/or absorption from gut microbiota of TPP which warrants further investigation. Increased plasma protein dityrosine may reflect increased dual oxidase activity in response to change in mucosal immunity and host-microbe homeostasis.

In Thailand, family nurses are expected to provide support for older persons and their family members to promote healthy aging. Family bonds are strong, and relatives are expected to take care of their older family members. However, there is limited research on how older persons' family members perceive healthy aging. This study aimed to describe the conceptions of healthy aging held by the children and grandchildren of older persons in northeast Thailand. In a phenomenographic study, 14 interviews were performed to qualitatively analyze different conceptions of healthy aging. Four descriptive categories emerged: being independent, not being afflicted by diseases or illnesses, being a giver and a receiver, and being wise. The conceptions of healthy aging entail both autonomy and interdependence. The relative's perspective needs to be considered when policies relating to healthy aging are implemented in the community and when family nurses provide support to families to promote healthy aging.

Increasing evidence demonstrates that risk factors for chronic diseases are established during childhood and adolescence. Consensus about the need to increase prevention efforts makes the adoption of a healthy lifestyle seem desirable from early childhood onwards. After reviewing educational tools for children and adolescents aimed at promoting a healthy lifestyle, it was recognized that there was a need to develop a simple educational tool specifically designed for these age groups. Development of the healthy lifestyle pyramid for children and adolescents. We propose a three-dimensional, truncated and staggered pyramid with 4 faces and a base, which introduces a completely new concept that goes beyond other published pyramids. Each of the faces is oriented towards achieving a different goal. Two faces (faces 1 and 2) are formulated around achieving a goal on a daily basis (daily food intake, face 1, and daily activities, face 2). Face 3 is an adaptation of the traditional food guide pyramid, adapted to children's energy, nutritional and hydration needs. Face 4 deals with both daily and life-long habits. On the base of the pyramid, there is advice about adequate nutrition alternating with advice about physical activity and sports. The Healthy Lifestyle Pyramid is specifically developed for children and adolescents according to current scientific knowledge and evidence-based data and includes easy-to-follow advice and full colour pictures. Following these guidelines should improve health and reduce risk factors, promoting enjoyable and appropriate development towards adulthood.

To evaluate the effectiveness of the 'Healthy Dads, Healthy Kids (HDHK)' program when delivered by trained facilitators in community settings. A two-arm randomized controlled trial of 93 overweight/obese fathers (mean [SD] age=40.3 [5.3] years; BMI=32.5 [3.8] kg/m(2)) and their primary school-aged children (n=132) from the Hunter Region, Australia. In 2010-2011, families were randomized to either: (i) HDHK intervention (n=48 fathers, n=72 children) or (ii) wait-list control group. The 7-week intervention included seven sessions and resources (booklets, pedometers). Assessments were held at baseline and 14-weeks with fathers' weight (kg) as the primary outcome. Secondary outcomes for fathers and children included waist, BMI, blood pressure, resting heart rate, physical activity (pedometry), and self-reported dietary intake and sedentary behaviors. Linear mixed models (intention-to-treat) revealed significant between-group differences for fathers' weight (P<.001, d=0.24), with HDHK fathers losing more weight (-3.3 kg; 95%CI, -4.3, -2.4) than control fathers (0.1 kg; 95%CI, -0.9,1.0). Significant treatment effects (P<.05) were also found for fathers' waist (d=0.41), BMI (d=0.26), resting heart rate (d=0.59), energy intake (d=0.49) and physical activity (d=0.46) and for children's physical activity (d=0.50) and adiposity (d=0.07). HDHK significantly improved health outcomes and behaviors in fathers and children, providing evidence for program effectiveness when delivered in a community setting. Copyright © 2013.

Increasing prevalence of childhood obesity calls for comprehensive and cost-effective educative measures in developing countries such as India. School-based educative programmes greatly influence children's behaviour towards healthy living. We aimed to evaluate the impact of a school-based health and nutritional education programme on knowledge and behaviour of urban Asian Indian school children. Benchmark assessment of parents and teachers was also done. We educated 40 196 children (aged 8-18 years), 25 000 parents and 1500 teachers about health, nutrition, physical activity, non-communicable diseases and healthy cooking practices in three cities of North India. A pre-tested questionnaire was used to assess randomly selected 3128 children, 2241 parents and 841 teachers before intervention and 2329 children after intervention. Low baseline knowledge and behaviour scores were reported in 75-94 % government and 48-78 % private school children, across all age groups. A small proportion of government school children gave correct answers about protein (14-17 %), carbohydrates (25-27 %) and saturated fats (18-32 %). Private school children, parents and teachers performed significantly better than government school subjects (P < 0.05). Following the intervention, scores improved in all children irrespective of the type of school (P < 0.001). A significantly higher improvement was observed in younger children (aged 8-11 years) as compared with those aged 12-18 years, in females compared with males and in government schools compared with private schools (P < 0.05 for all). Major gaps exist in health and nutrition-related knowledge and behaviour of urban Asian Indian children, parents and teachers. This successful and comprehensive educative intervention could be incorporated in future school-based health and nutritional education programmes.

Plasma norepinephrine and epinephrine in vibration syndrome subjects and age-matched healthy controls were measured for the purpose of estimating the responsibility of the sympathetic nervous system to cold exposure. In preliminary experiment, it was confirmed that cold air exposure of the whole body was more suitable than one-hand immersion in cold water. In the main experiment, 195 subjects were examined. Sixty-five subjects had vibration syndrome with vibration-induced white finger (VWF + group) and 65 subjects had vibration syndrome without VWF (VWF- group) and 65 controls had no symptoms (control group). In the three groups, plasma norepinephrine levels increased during cold air exposure of whole body at 7 degrees +/- 1.5 degrees C. Blood pressure increased and skin temperature decreased during cold exposure. Percent increase of norepinephrine in the VWF+ group was the highest while that in VWF- group followed and that in the control group was the lowest. This whole-body response of the sympathetic nervous system to cold conditions reflected the VWF which are characteristic symptoms of vibration syndrome. Excluding the effects of shivering and a cold feeling under cold conditions, it was confirmed that the sympathetic nervous system in vibration syndrome is activated more than in the controls. These results suggest that vibration exposure to hand and arm affects the sympathetic nervous system.

Many features of fibromyalgia and hypothyroidism are virtually the same, and thyroid hormone treatment trials have reduced or eliminated fibromyalgia symptoms. These findings led the authors to test the hypothesis that fibromyalgia patients are hypometabolic compared to matched controls. Resting metabolic rate (RMR) was measured by indirect calorimetry and body composition by bioelectrical impedance for 15 fibromyalgia patients and 15 healthy matched controls. Measured resting metabolic rate (mRMR) was compared to percentages of predicted RMR (pRMR) by fat-free weight (FFW) (Sterling-Passmore: SP) and by sex, age, height, and weight (Harris-Benedict: HB). Patients had a lower mRMR (4,306.31+/-1077.66 kJ vs 5,411.59+/-695.95 kJ, p=0.0028) and lower percentages of pRMRs (SP: -28.42+/-15.82% vs -6.83+/-12.55%, p<0.0001. HB: -29.20+/-17.43% vs -9.13+/-9.51%, p=0.0008). Whereas FFW, age, weight, and body mass index (BMI) best accounted for variability in controls' RMRs, age and fat weight (FW) did for patients. In the patient group, TSH level accounted for 28% of the variance in pain distribution, and free T3 (FT3) accounted for 30% of the variance in pressure-pain threshold. Patients had lower mRMR and percentages of pRMRs. The lower RMRs were not due to calorie restriction or low FFW. Patients' normal FFW argues against low physical activity as the mechanism. TSH, FT4, and FT3 levels did not correlate with RMRs in either group. This does not rule out inadequate thyroid hormone regulation because studies show these laboratory values do not reliably predict RMR.

To assess nutrient intake, growth and nutritional status of infants with cow's milk allergy (CMA) who follow a therapeutic elimination diet since the first few months of life. Sixty infants younger than four months of age with challenge-proven CMA and 60 healthy age-matched children were investigated. Anthropometric and body composition (BC) were assessed up to 24 months. Dietary intake was recorded by the parents for three consecutive days before visits at 6, 12, 18 and 24 months. Blood albumin, prealbumin, retinol binding protein and metabolic-related hormones were examined at 24 months. The average age at enrolment was 2.9 ± 1.0 months. At the end of the follow-up, there were no differences in daily milk consumption, nutrient intake, weight and height z scores or BC measures between the groups; however, the plasma leptin level was lower in infants with CMA (1.67 ± 1.03 vs 2.05 ± 1.48) (ng/mL) (p < 0.05) compared to healthy children. Children with CMA who followed an elimination diet could achieve a normal nutritional status, except for relatively lower plasma leptin levels, at the age of 2. Further studies with larger cohorts and research on the long-term consequences of these early differences are needed. ©2018 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

Conceptions of Healthy Aging Held by Relatives of Older Persons in Isan-Thai Culture: A Phenomenographic Study

In Thailand, family nurses are expected to provide support for older persons and their family members to promote healthy aging. Family bonds are strong, and relatives are expected to take care of their older family members. However, there is limited research on how older persons' family members perceive healthy aging. This study aimed to describe the conceptions of healthy aging held by the children and grandchildren of older persons in northeast Thailand. In a phenomenographic study, 14 interviews were performed to qualitatively analyze different conceptions of healthy aging. Four descriptive categories emerged: being independent, not being afflicted by diseases or illnesses, being a giver and a receiver, and being wise. The conceptions of healthy aging entail both autonomy and interdependence. The relative's perspective needs to be considered when policies relating to healthy aging are implemented in the community and when family nurses provide support to families to promote healthy aging.

Although the etiology and pathology of autism spectrum disorder (ASD) is still poorly understood, a number of environmental, anthropological, neurobiological and genetic factors have been related to the pathophysiology of ASD, even the impact of oxidative stress response related to the environment and nutrition intake. Usual recommended dietary habits are based on the combination of behavioral and dietary or nutraceutical interventions together with pharmacotherapy. Investigations about a reliable relationship between diet and ASD are still lacking. The present study aimed at comparing dietary regimens and habits of normally developing apparently healthy children, without diagnosed ASD, with a pediatric population of individuals affected by autistic disorder. Assessments of nutritional and anthropometric data, in addition to biochemical evaluation for nutrient deficiencies, were performed. A total of 80 children with autistic disorder and 80 healthy, normally developing pediatric individuals were enrolled in the study. Parents were asked to complete the standardized questionnaire regarding the different types of food and the proportion of a serving for their children. Biochemical analysis of micro- and macronutrients were also done. Plotting on the Egyptian sex-specific anthropometric growth (auximetric) chart, absolute weights as well as weight-related for age classes, were significantly higher in cases than healthy controls. No differences between groups were observed in regard to total kilocalories (kcal), carbohydrates, and fat intake. A total of 23.8% of children with autistic disorder vs. 11.3% in the healthy control group had a nutrient intake with features below the Recommended Dietary Allowance (RDA) of protein. Children with autistic disorder showed low dietary intake of some micronutrients; calcium (Ca), magnesium (Mg), iron (Fe), selenium (Se) and sodium (Na), also they had significantly high intake of potassium (K) and vitamin C compared to healthy

To describe the immunogenicity and side effects of immunisation against hepatitis A virus (HAV) in JIA patients on methotrexate treatment, who have not been previously exposed to HAV. Case-control study performed in JIA patients and healthy controls matched on age and gender. The subjects received two doses of inactivated anti-HAV vaccine (720 mIU/ml) intramuscularly at 0 and 6 months. Seroconversion, seroprotection rates and anti-HAV-IgG titres were measured at 1, 7 and 18 months. Children were monitored for adverse events. 83 JIA patients and 76 controls were enrolled in the study. At one month, seroprotection rates were lower in children with, as compared to those without JIA (48.2% vs. 65%; p=0.05). At 7 and 18 months, rates of seroprotection rose significantly and were similar in both groups. The titre of anti-HAV-IgG was lower in children with JIA than healthy children at all time points (p<0.001). Vaccines were well tolerated. Two doses of inactivated HAV vaccine were well tolerated and immunogenic in most immunosuppressed children with JIA; however, a single dose of HAV vaccine was insufficient to induce seroprotection in half of the patients. Further studies are required to analyse the long-term immunity against HAV in this population and optimal HAV immunisation regimen.

Introduction Our aim was to estimate the longitudinal effect of Socioeconomic status (SES) on lung function growth of Mexican children and adolescents. Materials and Methods A cohort of Mexican children in third grade of primary school was followed with spirometry twice a year for 6 years through secondary school. Multilevel mixed-effects lineal models were fitted for the spirometric variables of 2,641 respiratory-healthy Mexican children. Monthly family income (in 2002 U.S. dollars [USD]) and parents’ years completed at school were used as proxies of SES. Results Individuals with higher SES tended to have greater height for age, and smaller sitting height/standing height and crude lung function. For each 1-year increase of parents’ schooling, Forced expiratory volume in 1 sec (FEV1) and Forced vital capacity (FVC) increased 8.5 (0.4%) and 10.6 mL (0.4%), respectively (p <0.05) when models were adjusted for gender. Impact of education on lung function was reduced drastically or abolished on adjusting by anthropometric variables and ozone. Conclusions Higher parental schooling and higher monthly family income were associated with higher lung function in healthy Mexican children, with the majority of the effect likely due to the increase in height-for-age.

Muscle synergies are hypothesized to represent motor modules recruited by the nervous system to flexibly perform subtasks necessary to achieve movement. Muscle synergy analysis may offer a better view of the neural structure underlying motor behaviors and how they change in motor deficits and rehabilitation. The aim of this study is to investigate if muscle synergies are able to encode regularities in the musculoskeletal system organization and dynamic behavior of patients with dystonia, or if they are altered as a consequence of the nervous system dysfunction in dystonia. To do so, we applied muscle synergies analysis to muscle activity recorded during the execution of upper limb writing tasks in 10 children with dystonia and 9 age-matched healthy controls. We show that, although children with dystonia present movement abnormalities compared to control subjects, the muscle synergies extracted from the two groups are very similar, and that the two groups share a significant number of motor modules. Our finding therefore suggests that a regular modular organization of upper limb muscle coordination is preserved for childhood dystonia.

A Parental Health Education Model of Children's Food Consumption: Influence on Children's Attitudes, Intention, and Consumption of Healthy and Unhealthy Foods.

2017-05-01

This study proposes that parental mediation of television advertising and parental guidance of food consumption differentially influence children's attitude, intention, and behavior toward the consumption of healthy and unhealthy foods. Structural equation modeling based on a survey of 1,119 children aged 9-12 supported our model, revealing that parental education strategies influence children's food consumption in a complex manner that is highly context-dependent. Parental guidance of food consumption enhanced children's healthy food attitude and intention to consume, while reducing the intention to consume unhealthy food. However, parental mediation of television advertising influenced unhealthy food attitude to a greater extent than healthy food attitude. Implications for health promotion and education, as well as parents and policy makers are discussed.

This study examines explicit memory bias for emotional information in children and adolescents with major depressive disorder (MDD). Participants were a convenient sample of 28 children and adolescents of mothers with MDD, 28 children and adolescents with MDD, and 29 healthy controls. Their age range was 11-17 years old. The groups were matched for gender ratio, mean age, and the years of educational level. They were assessed by the Recall Task. Emotional stimuli consisted of three sets of words namely sad, happy, and neutral words. Children and adolescents of mothers with MDD similar to children and adolescents with MDD recalled more sadness stimuli in comparison with the controls. In other words, they showed an explicit memory bias towards sad stimuli. Also, healthy children significantly recalled more happy words than the other two groups. There was no significant difference among the three groups for the recall of neutral stimuli. Current findings support that there is a recall memory bias for emotional information in children with MDD. These children more than healthy children recall sad words. Moreover, healthy children recall happy words more than children with MDD. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Unsuitable footwear worn in childhood may cause some foot problems by interfering normal development of foot. To compare footwear suitability rate of indoor and outdoor footwear at all points in preschool children and investigate factors which could affect footwear suitability. A cross-sectional survey study. A total of 1000 healthy preschool children (4-6 years old) participated in this study. Indoor and outdoor footwear of children were evaluated through Turkish version of Footwear Assessment Score. Effect of factors like age, sex, number of siblings, educational and occupational situation of parents, and behavior of school management about selecting footwear was investigated. Children got better footwear score for outdoor than indoor ones (p < 0.001). Boys got statistically better footwear score for both indoor and outdoor ones than girls (p < 0.001). Also significant difference in footwear score was found in favor of children who were going to schools that gave guidance about selecting footwear for both indoor and outdoor in comparison to children going to other schools (p < 0.001). For healthy foot development, parents need an education about suitable footwear for their children. Performing education programs and investigation of their effect with comprehensive follow-up studies in future is essential. This study reflects footwear habits of Turkish preschool children and factors affecting this issue. Results may give way to education programs about suitable footwear worn in childhood for healthy foot development. © The International Society for Prosthetics and Orthotics 2013.

Aim To determine the age of development of bladder and bowel control and the frequency of enuresis, encopresis, and urinary infections in children with cerebral palsy. Methods The study included 45 children with cerebral palsy who regularly attended a rehabilitation center in Isparta, Turkey, and two groups of age- and sex-matched children, 37 siblings of the children with cerebral palsy and 37 healthy children. Demographic data and information on the age of development of total bladder and bowel control and presence of possible urinary symptoms in children were collected from their caregivers by use of a questionnaire. Frequency of enuresis and encopresis was estimated among the children aged ≥5 years. A mid-way urinary sample was obtained from 40, 22, and 21 children in the cerebral palsy, siblings, and healthy children, respectively. Results The mean age of nighttime bladder and bowel control development was 47 months (95% confidence interval [CI], 35-58) and 45 (36-55) months, respectively, for the children with cerebral palsy, 35 months (95% CI, 24-46) and 26 months (95% CI, 24-28), respectively, for their siblings, and 27 months (95% CI, 22-33) and 25 months (95% CI, 23-27) months, respectively, for the healthy children. Among the children aged ≥5 years, enuresis was present in 11 of 34 children with cerebral palsy, 7 of 30 siblings, and 4 of 30 healthy children (P = 0.200), whereas encopresis was present in 5 children with cerebral palsy, one sibling, and one healthy child. Constipation was significantly more present in chidlren with cerebral palsy than in other two groups (P<0.001). Urine culture was positive in 13 children with cerebral palsy, 1 sibling, and 2 healthy chidlren (P = 0.024). There were no significant differences in other urinary symptoms and laboratory findings among the three groups. Conclusion The children with cerebral palsy gained bladder and bowel control at older age in comparison with their siblings and healthy children

The purpose of this study was to establish normative reference values for spatiotemporal and plantar pressure parameters, and to investigate the influence of demographic, anthropometric and physical characteristics. In 1000 healthy males and females aged 3-101 years, spatiotemporal and plantar pressure data were collected barefoot with the Zeno™ walkway and Emed ® platform. Correlograms were developed to visualise the relationships between widely reported spatiotemporal and pressure variables with demographic (age, gender), anthropometric (height, mass, waist circumference) and physical characteristics (ankle strength, ankle range of motion, vibration perception) in children aged 3-9 years, adolescents aged 10-19 years, adults aged 20-59 years and older adults aged over 60 years. A comprehensive catalogue of 31 spatiotemporal and pressure variables were generated from 1000 healthy individuals. The key findings were that gait velocity was stable during adolescence and adulthood, while children and older adults walked at a comparable slower speed. Peak pressures increased during childhood to older adulthood. Children demonstrated highest peak pressures beneath the rearfoot whilst adolescents, adults and older adults demonstrated highest pressures at the forefoot. Main factors influencing spatiotemporal and pressure parameters were: increased age, height, body mass and waist circumference, as well as ankle dorsiflexion and plantarflexion strength. This study has established whole of life normative reference values of widely used spatiotemporal and plantar pressure parameters, and revealed changes to be expected across the lifespan.

Young children's knowledge about healthy food may influence the formation of their eating behaviours, and parents have a major influence on the development of children's knowledge in the early years. We investigated the extent to which parental nutrition knowledge and attitudes around food predicted young children's knowledge of healthy foods, controlling for other influences such as socio-economic status (SES) and parent education levels in a cross-sectional research design. Children were given a healthy food knowledge activity and parents completed questionnaires. Twenty primary schools in Adelaide, Australia, stratified by SES. We recruited 192 children aged 5-6 years and their parents. Structural equation modelling showed that parent nutrition knowledge predicted children's nutrition knowledge (r = 0·30, P < 0·001) independently of attitudes, SES and education level. Nutrition education for parents, targeted at low-SES areas at higher risk for obesity, may contribute to the development of healthy food knowledge in young children.

Abnormalities of humoral and cell-mediated immunity have been described in Down syndrome but reported findings have been inconsistent. Confounding factors have included age, institutional versus home life, hepatitis B antigenemia, and zinc deficiency. To clarify this problem, we studied 64 children with Down syndrome (DS) compared with an age-matched control group. All children had always lived at home. All the DS children were negative for hepatitis B surface antigen. Serum zinc concentration in the DS group was on average 12 micrograms/dl lower than age-matched control children. They also had significantly lower levels of immunoglobulin M, total lymphocyte count, T and B lymphocytes, and T helper and suppressor cells. In vitro lymphocyte response to phytohemagglutinin and concanavalin A was significantly reduced at all ages in the DS group. Lymphocyte response to pokeweed mitogen increased with age in control children but decreased in the DS children. By 18 yr, the mean response for DS was 60000 cpm lower than controls. The DS group had significantly higher concentrations of immunoglobulins A and G than controls and the difference increased with age. Complement fractions C3 and C4 were also higher in the DS group at all ages. The number of HNK-1 positive cells was higher in the DS group than controls at all ages. When hepatitis and institutionalization are excluded as confounding factors, DS children still differ in both humoral and cell-mediated immunity from an age-matched control group.

Focusing on relevant information while suppressing the irrelevant one are critical abilities for different cognitive processes. However, their functioning has been scarcely investigated in the working memory (WM) domain, in both healthy and pathological conditions. The present research aimed to study these abilities in aging and Parkinson's disease (PD), testing three groups of healthy participants (young, older and elderly) and one of PD patients, employing a new experimental paradigm. Results showed that the transient storing of irrelevant information in WM causes substantial interference effects, which were remarkable in elderly individuals on both response latency and accuracy. Interestingly, PD patients responded faster and were equally accurate compared to a matched control group. Taken together, findings confirm the existence of similar mechanisms for orienting attention inwards to WM contents or outwards to perceptual stimuli, and suggest the suitability of our task to assess WM functioning in both healthy aging and PD.

The public health policy agenda oriented towards healthy ageing becomes the highest priority for the European countries. The article discusses the healthy ageing concept and its possible determinants with an aim to identify behavioral patterns related to healthy ageing in selected European countries. The healthy ageing is assessed based on a composite indicator of self-assessed health, functional capabilities and life meaningfulness. The logistic regression models are used to assess the impact of the healthy lifestyle index, psycho-social index and socio-economic status on the probability of healthy ageing (i.e. being healthy at older age). The lifestyle and psychosocial indexes are created as a sum of behaviors that might be important for healthy ageing. Models are analyzed for three age groups of older people: 60-67, 68-79 and 80+ as well as for three groups of countries representing Western, Southern and Central-Eastern Europe. The lifestyle index covering vigorous and moderate physical activity, consumption of vegetables and fruits, regular consumption of meals and adequate consumption of liquids is positively related to healthy ageing, increasing the likelihood of being healthy at older age with each of the items specified in the index. The score of the index is found to be significantly higher (on average by 1 point for men and 1.1 for women) for individuals ageing healthily. The psychosocial index covering employment, outdoor social participation, indoor activities and life satisfaction is also found to be significantly related to health increasing the likelihood of healthy ageing with each point of the index score. There is an educational gradient in healthy ageing in the population below the age of 68 and in Southern and Central-Eastern European countries. In Western European countries, income is positively related to healthy ageing for females. Stimulation physical activity and adequate nutrition are crucial domains for a well-defined public health policy

Healthy mental ageing.

Flicker, Leon; Lautenschlager, Nicola T; Almeida, Osvaldo P

2006-09-01

Healthy mental ageing may be defined as the absence of the common disabling mental health problems of older people, especially cognitive decline and depression, accompanied by the perception of a positive quality of life. Older people are particularly prone to negative effects on mental health due to poor physical health. Modifiable aspects of lifestyle have been shown to be associated with healthy mental ageing. These include increased physical activity, intellectual stimulation (including education), avoidance of smoking and various aspects of diet. There is reasonably strong evidence that the treatment of hypertension will decrease the risk of cognitive impairment, and moderate alcohol intake may also have some benefits on cognition. These modifiable lifestyle factors may benefit from deliberate individual and population health promotion strategies to maximize mental health in old age, although to date intervention trials have not been performed to support the evidence obtained from observational studies.

Diagnostics of the human ageing process may help predict future healthcare needs or guide preventative measures for tackling diseases of older age. We take a transcriptomics approach to build the first reproducible multi-tissue RNA expression signature by gene-chip profiling tissue from sedentary normal subjects who reached 65 years of age in good health. One hundred and fifty probe-sets form an accurate classifier of young versus older muscle tissue and this healthy ageing RNA classifier performed consistently in independent cohorts of human muscle, skin and brain tissue (n = 594, AUC = 0.83-0.96) and thus represents a biomarker for biological age. Using the Uppsala Longitudinal Study of Adult Men birth-cohort (n = 108) we demonstrate that the RNA classifier is insensitive to confounding lifestyle biomarkers, while greater gene score at age 70 years is independently associated with better renal function at age 82 years and longevity. The gene score is 'up-regulated' in healthy human hippocampus with age, and when applied to blood RNA profiles from two large independent age-matched dementia case-control data sets (n = 717) the healthy controls have significantly greater gene scores than those with cognitive impairment. Alone, or when combined with our previously described prototype Alzheimer disease (AD) RNA 'disease signature', the healthy ageing RNA classifier is diagnostic for AD. We identify a novel and statistically robust multi-tissue RNA signature of human healthy ageing that can act as a diagnostic of future health, using only a peripheral blood sample. This RNA signature has great potential to assist research aimed at finding treatments for and/or management of AD and other ageing-related conditions.

Survival prospects for adults with repaired tetralogy of Fallot (TOF) are now excellent. Attention should therefore shift to assessing and improving functional health status and quality of life. We aimed to assess late functional health status of adults surviving TOF repair by matched comparison to their healthy siblings. All 1,693 TOF repairs performed at our institution between 1946 and 1990 were reviewed. A matched comparison was undertaken whereby presumed survivors and their healthy sibling were contacted and asked to complete the Ontario Health Survey 1990 and the 36-Item Short Form Health Survey (SF-36) questionnaire. Both questionnaires were completed by 224 adult survivors and their sibling closest in age. Adults with repaired TOF had lower scores for self-perceived general health status (p < 0.001), were less likely to rate their health as good or excellent (p < 0.001), and had lower SF-36 scores for physical functioning and general health (p = 0.001) than their siblings. However, patients reported similar satisfaction with their lives, similar levels of social participation and support, and were as likely to be in long-term partnerships. Worse physical and mental health scores were associated with older age at surgery and at time of questionnaire completion and recent requirement for noncardiac medication. Although reporting lower functional health status then their siblings, quality of life and life satisfaction for adults who underwent surgery for TOF during childhood is comparable to that of their siblings without heart defects. Follow-up of younger adults is required to understand current health outcomes attributable to improvements in the management of TOF. Copyright © 2012 The Society of Thoracic Surgeons.

Additionally, intelligence has been associated with the volume of gray matter in the brains of children. Based on these correlations, we analyzed the correlation among height, full-scale intelligence quotient (IQ) and gray matter volume applying voxel-based morphometry using data from the brain magnetic resonance images of 160 healthy children aged 5-18 years of age. As a result, body height was significantly positively correlated with brain gray matter volume. Additionally, the regional gray matter volume of several regions such as the bilateral prefrontal cortices, temporoparietal region, and cerebellum was significantly positively correlated with body height and that the gray matter volume of several of these regions was also significantly positively correlated with full-scale intelligence quotient (IQ) scores after adjusting for age, sex, and socioeconomic status. Our results demonstrate that gray and white matter volume may mediate the correlation between body height and intelligence in healthy children. Additionally, the correlations among gray and white matter volume, height, and intelligence may be at least partially explained by the effect of insulin-like growth factor-1 and growth hormones. Given the importance of the effect of environmental factors, especially nutrition, on height, IQ, and gray matter volume, the present results stress the importance of nutrition during childhood for the healthy maturation of body and brain.

The UK commenced an extension to the seasonal influenza vaccination policy in autumn 2014 that will eventually see all healthy children between the ages of 2-16 years offered annual influenza vaccination. Models suggest that the new policy will be both highly effective at reducing the burden of influenza as well as cost-effective. We explore whether targeting vaccination at either primary or secondary schools would be more effective and/or cost-effective than the current strategy. An age-structured deterministic transmission dynamic SEIR-type mathematical model was used to simulate a national influenza outbreak in England. Costs including GP consultations, hospitalisations due to influenza and vaccinations were compared to potential gains in quality-adjusted life years achieved through vaccinating healthy children. Costs and benefits of the new JCVI vaccination policy were estimated over a single season, and compared to the hypothesised new policies of targeted and heterogeneous vaccination. All potential vaccination policies were highly cost-effective. Influenza transmission can be eliminated for a particular season by vaccinating both primary and secondary school children, but not by vaccinating only one group. The most cost-effective policy overall is heterogeneous vaccination coverage with 48% uptake in primary schools and 34% in secondary schools. The Joint Committee on Vaccination and Immunisation can consider a modification to their policy of offering seasonal influenza vaccinations to all healthy children of ages 2-16 years.

Whyatt, Caroline P; Craig, Cathy M

2012-09-01

This study used the Movement Assessment Battery for Children (M-ABC2) to assess motor skills in children aged 7-10 years with autism (n = 18) in comparison to two groups of age-matched typically developing children; a receptive vocabulary matched group (n = 19) and a nonverbal IQ matched group (n = 22). The results supported previous work, as indicated by a significant general motor impairment in the group with autism. However, sub-analysis of the M-ABC2 revealed that there were only 2 out of 8 subcomponent skills which showed universal significant specific deficits for the autism group; i.e. catching a ball and static balance. These results suggest that motor skill deficits associated with autism may not be pervasive but more apparent in activities demanding complex, interceptive actions or core balance ability.

Apparently healthy preschool children (46 boys, 52 girls) aged 27-50 mo from low socioeconomic conditions who attended daycare centers in Santiago participated in a 14-mo long double-blind zinc supplementation trial. Unlike most previous studies, no additional inclusion criteria such as short stature or slow growth rate were considered. Subjects were pair matched according to sex and age and randomly assigned to two experimental groups: the supplemented group, which received 10 mg Zn/d, and the placebo group. Selected anthropometric, clinical, dietary, biochemical, and functional indexes were determined at the beginning of the study and after 6 and 14 mo of intervention. Actual dietary zinc intake was 66% of the recommended dietary allowance. Height gain after 14 mo was on average 0.5 cm higher in the supplemented group (P = 0.10). The response, however, was different between sexes. Boys from the supplemented group gained 0.9 cm more than those in the placebo group (P = 0.045). No effect was seen in girls. Although no significant differences were observed in the rest of the variables studied, trends (0.05 < P < 0.10) in the supplemented group compared with the placebo group for increased midarm muscle area in boys, improved response to tuberculin, and reduced rates of parasite reinfestation were noted. We conclude that in preschool children of low socioeconomic status, zinc is a limiting factor in the expression of growth potential.

Quantitative ultrasound measurements and bone metabolic markers can help to monitor bone health and to detect impaired skeletal development. Population-based reference values for children may serve as a basis for preventive measures to reduce the risk of osteoporosis and osteoporotic fractures in later life. This is the first paper providing age-, sex- and height-specific reference values for bone stiffness index (SI) and serum carboxy-terminal cross-linking telopeptide of type I collagen (CTX) in healthy, apparently prepubertal children. In the population-based IDEFICS baseline survey (2007-2008) and follow-up (2009-2010), 18,745 children from eight European countries were newly recruited. A total of 10,791 2-10.9-year-old and 1646 3-8.9-year-old healthy children provided data on SI of the right and left calcaneus and serum CTX, respectively. Furthermore, height and weight were measured. Percentile curves were calculated using the General Additive Model for Location Scale and Shape (GAMLSS) to model the distribution of SI and CTX depending on multiple covariates while accounting for dispersion, skewness, and the kurtosis of this distribution. SI was negatively associated with age and height in children aged 2-5 years, whereas a positive association was observed in children aged 6-10 years. The dip in SI occurred at older age for higher SI percentiles and was observed earlier in taller children than in smaller children. The CTX reference curves showed a linear-positive association with age and height. No major sex differences were observed for the SI and CTX reference values. These reference data lay the ground to evaluate bone growth and metabolism in prepubertal children in epidemiological and clinical settings. They may also inform clinical practice to monitor skeletal development and to assess adverse drug reactions during medical treatments.

Recent research has shown that the Fitkids Treadmill Test (FTT) is a valid and reproducible exercise test for the assessment of aerobic exercise capacity in children and adolescents who are healthy. The study objective was to provide sex- and age-related normative values for FTT performance in children and adolescents who were healthy, developing typically, and 6 to 18 years of age. This was a cross-sectional, observational study. Three hundred fifty-six children and adolescents who were healthy (174 boys and 182 girls; mean age=12.9 years, SD=3.7) performed the FTT to their maximal effort to assess time to exhaustion (TTE). The least-mean-square method was used to generate sex- and age-related centile charts (P3, P10, P25, P50, P75, P90, and P97) for TTE on the FTT. In boys, the reference curve (P50) showed an almost linear increase in TTE with age, from 8.8 minutes at 6 years of age to 16.1 minutes at 18 years of age. In girls, the P50 values for TTE increased from 8.8 minutes at 6 years of age to 12.5 minutes at 18 years of age, with a plateau in TTE starting at approximately 10 years of age. Youth who were not white were underrepresented in this study. This study describes sex- and age-related normative values for FTT performance in children and adolescents who were healthy, developing typically, and 6 to 18 years of age. These age- and sex-related normative values will increase the usefulness of the FTT in clinical practice. © 2016 American Physical Therapy Association.

Changing course in ageing research: The healthy ageing phenotype.

Ageing is often associated with the aged and the diseased, nevertheless ageing is a process that starts in-uterus and is characterised by a progressive functional loss but not necessarily by the presence of disease and poor quality of life. How to meander through life without crossing the confines of major chronic disease and cognitive and physical impairment remains one of the most relevant challenges for science and humankind. Delimiting that 'immaculate' trajectory - that we dub as the 'Healthy Ageing Phenotype' - and exploring solutions to help the population to stay or return to this trajectory should constitute the core focus of scientific research. Nevertheless, current efforts on ageing research are mainly focused on developing animal models to disentangle the human ageing process, and on age-related disorders often providing merely palliative solutions. Therefore, to identify alternative perspectives in ageing research, Unilever and the Medical Research Council (MRC) UK convened a Spark workshop entitled 'The Healthy Ageing Phenotype'. In this meeting, international specialists from complementary areas related to ageing research, gathered to find clear attributes and definitions of the 'Healthy Ageing Phenotype', to identify potential mechanisms and interventions to improve healthy life expectancy of the population; and to highlight areas within ageing research that should be prioritised in the future. General agreement was reached in recognising ageing research as a disaggregated field with little communication between basic, epidemiological and clinical areas of research and limited translation to society. A more holistic, multi-disciplinary approach emanating from a better understanding of healthy ageing trajectories and centred along human biological resilience, its maintenance and the reversibility from early deviations into pathological trajectories, is urgently required. Future research should concentrate on understanding the mechanisms that permit

Determinants of healthy eating in children and youth.

2005-01-01

This review outlines the state of knowledge and research gaps in the area of determinants of healthy eating among children and youth. The article is structured around individual and collective determinants that affect healthy eating in children and youth. We defined healthy eating as "eating practices and behaviours that are consistent with improving, maintaining and/or enhancing health." Relevant databases were searched for papers published between January 1992 and March 2003 that focussed on children or youth and reported at least one factor relevant to healthy eating. Among collective factors, familial factors and the nature of foods available in the physical environment, including at home, schools and in fast-food establishments, stand out as significant influences on healthy eating in children and youth. The media, particularly television, also have an enormous potential influence and can overshadow familial influences. Individual factors identified include knowledge, attitudes and food preferences; only the latter have been identified as a strong determinant of healthy eating in both children and adolescents. The results of the review identified a significant body of literature in the area of determinants of healthy eating in children and youth; however, very little of this research has taken place in Canada. Only a few determinants, such as economic factors and food security, the content of media nutritional messages, and the issue of flavours, neophobia and food preferences, have undergone some examination by Canadian researchers. Research priorities for Canada in the area of determinants of healthy eating and surveillance of eating behaviours are identified.

Ferdows, Nasim B; Jensen, Gail A; Tarraf, Wassim

This article examines the determinants of healthy aging using Grossman's framework of a health production function. Healthy aging, sometimes described as successful aging, is produced using a variety of inputs, determined in early life, young adulthood, midlife, and later life. A healthy aging production function is estimated using nationally representative data from the 2010 and 2012 Health and Retirement Study on 7,355 noninstitutionalized seniors. Using a simultaneous equation mediation model, we quantify how childhood factors contribute to healthy aging, both directly and indirectly through their effects on mediating adult outcomes. We find that favorable childhood conditions significantly improve healthy aging scores, both directly and indirectly, mediated through education, income, and wealth. We also find that good health habits have positive effects on healthy aging that are larger in magnitude than the effects of childhood factors. Our findings suggest that exercising, maintaining proper weight, and not smoking are likely to translate into healthier aging.

The diagnosis of Legg-Calvé-Perthes disease (LCPD) has a considerable influence on the daily life of the patients with restrictions in their leisure time activities. This might influence their mood. Until now this aspect of the disease has been neglected. Therefore the objective of the study was to evaluate the health related quality of life (HRQoL) of children with severe LCPD who had an extensive surgery with pelvic/femoral osteotomy. The KIDSCREEN-10 and the modified Modified Harris Hip Score (mHHS) -questionnaire were administered to 17 children (16 boys and 1 girl) aged 5 to 11 years at the time of surgery. Analyses of mHHS were made preoperatively and at the time of the follow-up examination at least 2 years postoperatively. KIDSCREEN-analyses were made postoperatively. The follow-up results were compared to an age-matched normal control group. Correlations were computed between KIDSCREEN-10 and mHHS pre- and post-operatively. The postoperative calculated KIDSCREEN-10-T-value [70.2 (SD 12.7)] was higher than the mean T-value of the control-group [56.6 (SD 10.4)]. The mHHS improved from 54.4 (SD 19.9) to a score of 99.5 (SD 1.5) postoperatively. A strong correlation was found between the preoperative mHHS and the postoperative KIDSCREEN-10-T-value (Spearman’s-rho 0.67, P=0.003). After containment improving surgery and a mean follow-up period of 4.2 years the HRQoL-status is even better compared with a healthy age-matched control group. As well an excellent clinical function could be achieved. PMID:25568729

To investigate the association between indices of sleep spindle activity and cognitive performance in a sample of healthy children. Correlational. Intelligence (Stanford-Binet) and neurocognitive functioning (NEPSY) were assessed, with sleep variables being measured during overnight polysomnography. Hospital sleep laboratory. Twenty-seven healthy children (mean age 8.19 y; 14 female, 13 male). N/A. Participants underwent a single night of overnight polysomnography after completing measures of intelligence and neurocognitive functioning. Sleep spindles were visually identified by an experienced sleep scoring technician and separated algorithmically into fast (> 13 Hz) and slow spindle (< 13 Hz) categories. The number of fast spindles was significantly correlated with narrative memory (r(s) = 0.38) and sensorimotor functioning (-0.43). Mean central frequency of spindles was also significantly correlated with sensorimotor functioning (-0.41), planning ability (-0.41), and working memory (-0.54). Basal sleep spindle activity is associated with different aspects of cognitive performance in children. To the extent that these associations in a pediatric population are different from what is known in adult sleep may play an important role in development.

Children identify liking and healthiness of foods as factors influencing their food choices. However, the food decision making process is also influenced by both personal characteristics and food contexts. The present study explored the influence of liking and perceived healthiness of foods in normal- and overweight children's food choices intentions in a pleasure-oriented social eating context and a health-oriented social eating context. Children aged from 6 to 11 years old (n = 63; 34 children who were of normal weight and 29 who were overweight) were asked to select 5 foods among 10, based on food pictures, to make up a snack that would be suitable for their birthday party or a nutrition class. In addition, they rated their liking and healthiness perception of the foods. No significant difference in food choices was found between children who were of normal weight and children who were overweight. Both groups of children chose more healthy food items in a health-oriented social context (i.e., a fictive nutrition class) than in a pleasure-oriented social context (i.e., a fictive birthday party). Moreover, only liking significantly predicted food choices in the pleasure-oriented social context whereas both healthiness and liking significantly predicted food choices in the health-oriented social context. Overall these results advance our understanding on how children make food decisions and inform strategies that may help children to adopt a healthy diet. Because liking predicted children's food choices in both eating contexts, emphasizing the "good" taste of healthy foods and providing children with healthy foods they like could be efficient strategies to promote healthy eating habits in children.

Parents' childhood experiences of trauma may influence their reports of their children's behavior, and this may be particularly true when children are also traumatized. The present study proposed and tested a matched trauma hypothesis, positing that compared to parents without a childhood history of witnessing domestic violence (DV), parents with a childhood history of witnessing DV may report their children's trauma-related symptomatology differently following children's exposure to DV. Of 137 included parents (M age = 32 years; 93% mothers), 81 reported witnessing childhood DV (matched group), whereas 56 reported no childhood DV exposure (nonmatched comparison group). All parents reported on their 3- to 6-year-old children's dissociation and posttraumatic stress symptoms following children's DV exposure. An analysis of covariance controlling for parental life stress, dissociation symptoms, and other childhood traumatic events revealed that parents who witnessed childhood DV reported significantly fewer child dissociation symptoms than comparison parents. No difference was found for parents' reports of children's posttraumatic stress symptoms. Exploratory analyses on a subsample of children with teacher reports of child dissociation symptoms (n = 75) revealed that the strength of the association between parent and teacher reports of dissociation symptoms was moderated by matched versus nonmatched group membership. Findings suggest the importance of considering a parent's history of trauma when using parents as informants for children's trauma symptoms.

Exhaled breath analysis is a potential non-invasive tool for diagnosing and monitoring airway diseases. Gas chromatography-mass spectrometry and electrochemical sensor arrays are the main techniques to detect volatile organic compounds (VOC) in exhaled breath. We developed a broadband quantum cascade laser spectroscopy technique for VOC detection and identification. The objective of this study was to assess the repeatability of exhaled breath profiling with broadband quantum cascade laser-based spectroscopy and to explore the clinical applicability by comparing exhaled breath samples from healthy children with those from children with asthma or cystic fibrosis (CF). Healthy children and children with stable asthma or stable CF, aged 6-18 years, were included. Two to four exhaled breath samples were collected in Tedlar bags and analyzed by quantum cascade laser spectroscopy to detect VOCs with an absorption profile in the wavenumber region between 832 and 1262.55 cm(-1). We included 35 healthy children, 39 children with asthma and 15 with CF. Exhaled breath VOC profiles showed poor repeatability (Spearman's rho  =  0.36 to 0.46) and agreement of the complete profiles. However, we were able to discriminate healthy children from children with stable asthma or stable CF and identified VOCs that were responsible for this discrimination. Broadband quantum cascade laser-based spectroscopy detected differences in VOC profiles in exhaled breath samples between healthy children and children with asthma or CF. The combination of a relatively easy and fast method and the possibility of molecule identification makes broadband quantum cascade laser-based spectroscopy attractive to investigate the diagnostic and prognostic potential of volatiles in exhaled breath.

Peak Expiratory Flow (PEF) has never been characterised among healthy Moroccan school children. To study the relationship between PEF and anthropometric parameters (sex, age, height and weight) in healthy Moroccan school children, to establish predictive equations of PEF; and to compare flowmetric and spirometric PEF with Forced Expiratory Volume in 1 second (FEV1). This cross-sectional study was conducted between April, 2016 and May, 2016. It involved 222 (122 boys and 100 girls) healthy school children living in Ksar el-Kebir, Morocco. We used mobile equipments for realisation of spirometry and peak expiratory flow measurements. SPSS (Version 22.0) was used to calculate Student's t-test, Pearson's correlation coefficient and linear regression. Significant linear correlation was seen between PEF, age and height in boys and girls. The equation for prediction of flowmetric PEF in boys was calculated as 'F-PEF = -187+ 24.4 Age + 1.61 Height' (p-value<0.001, r=0.86), and for girls as 'F-PEF = -151 + 17Age + 1.59Height' (p-value<0.001, r=0.86). The equation for prediction of spirometric PEF in boys was calculated as 'S-PEF = -199+ 9.8Age + 2.67Height' (p-value<0.05, r=0.77), and for girls as 'S-PEF = -181 + 8.5Age + 2.5Height' (p-value<0.001, r=0.83). The boys had higher values than the girls. The performance of the Mini Wright Peak Flow Meter was lower than that of a spirometer. Our study established PEF predictive equations in Moroccan children. Our results appeared to be reliable, as evident by the high correlation coefficient in this sample. PEF can be an alternative of FEV1 in centers without spirometry.

Prader-Willi syndrome (PWS) is a rare genetic neurodevelopmental disorder associated with maladaptive social behavior, hyperphagia and morbid obesity. Orexin A is a hypothalamic neuropeptide important as a homeostatic regulator of feeding behavior and in energy metabolism through actions in the lateral hypothalamus. Dysregulation of orexin signaling may contribute to behavioral problems and hyperphagia seen in PWS and we sought to assess orexin A levels in PWS relative to controls children. Morning fasting plasma orexin A levels were analyzed in 23 children (aged 5-11 years) with genetically confirmed PWS and 18 age and gender matched healthy unrelated siblings without PWS. Multiplex immune assays utilized the Milliplex Human Neuropeptide Magnetic panel and the Luminex platform. Natural log-transformed orexin A data were analyzed using general linear model adjusting for diagnosis, gender, age, total body fat, and body mass index (BMI). Plasma orexin A levels were significantly higher (P < 0.006) in children with PWS (average ±SD = 1,028 pg/ml ± 358) compared with unrelated siblings (average ±SD = 609 pg/ml ± 351; P < 0.001). Orexin A levels correlated with age in females and were significantly elevated in PWS even after these effects were controlled. These findings support the hypothesis that dysregulation of orexin signaling may contribute to behavioral problems and hyperphagia in PWS. Further studies are warranted to better understand the complex relationship between orexin A levels and the problematic behaviors consistently found in individuals with PWS. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

The impact of a healthy media use intervention on sleep in preschool children.

Garrison, Michelle M; Christakis, Dimitri A

2012-09-01

Although observational studies have consistently reported an association between media use and child sleep problems, it is unclear whether the relationship is causal or if an intervention targeting healthy media use can improve sleep in preschool-aged children. We conducted a randomized controlled trial of a healthy media use intervention in families of children aged 3 to 5 years. The intervention encouraged families to replace violent or age-inappropriate media content with quality educational and prosocial content, through an initial home visit and follow-up telephone calls over 6 months. Sleep measures were derived from the Child Sleep Habits Questionnaire and were collected at 6, 12, and 18 months after baseline; repeated-measures regression analyses were used. Among the 565 children analyzed, the most common sleep problem was delayed sleep-onset latency (38%). Children in the intervention group had significantly lower odds of "any sleep problem" at follow-up in the repeated-measures analysis (odds ratio = 0.36; 95% confidence interval: 0.16 to 0.83), with a trend toward a decrease in intervention effect over time (P = .07). Although there was no significant effect modification detected by baseline sleep or behavior problems, gender, or low-income status, there was a trend (P = .096) toward an increased effect among those with high levels of violence exposure at baseline. The significant effects of a healthy media use intervention on child sleep problems in the context of a randomized controlled trial suggest that the previously reported relationship between media use and child sleep problems is indeed causal in nature.

Objective: The purpose of this study was to explore the age-related brain activation changes during a word-matching semantic-category-based task, which required either repeating or changing a semantic rule to be applied. In order to do so, a word-semantic rule-based task was adapted from the Wisconsin Sorting Card Test, involving the repeated feedback-driven selection of given pairs of words based on semantic category-based criteria. Method: Forty healthy adults (20 younger and 20 older) performed a word-matching task while undergoing a fMRI scan in which they were required to pair a target word with another word from a group of three words. The required pairing is based on three word-pair semantic rules which correspond to different levels of semantic control demands: functional relatedness, moderately typical-relatedness (which were considered as low control demands), and atypical-relatedness (high control demands). The sorting period consisted of a continuous execution of the same sorting rule and an inferred trial-by-trial feedback was given. Results: Behavioral performance revealed increases in response times and decreases of correct responses according to the level of semantic control demands (functional vs. typical vs. atypical) for both age groups (younger and older) reflecting graded differences in the repetition of the application of a given semantic rule. Neuroimaging findings of significant brain activation showed two main results: (1) Greater task-related activation changes for the repetition of the application of atypical rules relative to typical and functional rules, and (2) Changes (older > younger) in the inferior prefrontal regions for functional rules and more extensive and bilateral activations for typical and atypical rules. Regarding the inter-semantic rules comparison, only task-related activation differences were observed for functional > typical (e.g., inferior parietal and temporal regions bilaterally) and atypical > typical (e

Healthy habits are influenced by several factors such as geographical location. The aims of this study were to describe and compare healthy habits within two populations of sixth-grade primary school children (aged 11-12 years) from northern and southern Spain. A cross-sectional study using two representative samples of school children was conducted. Participants came from Logroño ( n  = 329) in the north and Granada ( n  = 284) in the south of Spain. Socio-demographic and anthropometric variables, adherence to the Mediterranean diet, aerobic fitness, and healthy lifestyles were recorded. Boys reported a higher level of physical activity and aerobic fitness than girls ( p  = 0.000). Southern school children reported significantly higher adherence to the Mediterranean diet (♀: p  = 0.041; ♂: p  = 0.008), lower aerobic fitness (♀: p  = 0.000; ♂: p  = 0.042) and hours of nightly sleep (♀: p  = 0.008, ♂: p  = 0.007) than northern school children. Southern boys also reported lower levels of physical activity ( p  = 0.013). There were slight or moderate correlations among all habits measured (physical activity, diet, screen and sleep time). Additionally, the physical activity level was inversely related to weight status. Overweight and obese northern boys reported less physical activity than healthy-weight northern boys ( p  = 0.020) and overweight and obese southern girls reported less physical activity than healthy-weight southern girls ( p  = 0.024). Results showed differences in physical activity, eating and sleep habits, and aerobic fitness according to geographical location. The relationships found among lifestyle habits indicate the need for health promotion interventions nationally and considering the differences discussed here.

Magazine adverts for healthy and less healthy foods: effects on recall but not hunger or food choice by pre-adolescent children.

The marketing of foods to children has been criticised by parents and academics alike and the control of such advertising is being considered by politicians. Much of the current research focuses on TV advertising. This study aimed to investigate the effects of exposure to printed advertisements for healthy, less healthy and non-food products on children's mood, hunger, food choice and product recall. Accordingly, 309 children (mean age 9.7 years) received booklets in a quasi-random order. Each booklet contained one of the three types of adverts, ratings of current self-perception and a food choice measure. The booklets were presented as a school-based media literacy exercise. Body weight, height and body satisfaction were assessed 1 week later. The three groups did not differ in the effect on current state or end of session food choice. However, children recalled more of the less healthy food products, even when accounting for recent exposure. Greater product recall of less healthy foods is relevant to future consumption but has a number of possible interpretations. The further exploration of non-TV food marketing is warranted at a time when marketing through these channels is increasing, not least as a result of greater TV advertising regulations.

The purpose of this study was to examine differences in heart rate recovery (HRRec) and oxygen consumption recovery (VO 2 recovery) between young healthy-weight children and children with obesity following a maximal volitional graded exercise test (GXTmax). Twenty healthy-weight children and 13 children with obesity completed body composition testing and performed a GXTmax. Immediately after the GXTmax, HRRec and VO 2 recovery were measured each minute for 5 consecutive minutes. There were no statistically significant group differences in HRRec for the 5 min following maximal exercise, Wilks's Lambda = .885, F(4, 28) = 0.911, p = .471, between the healthy-weight children and children with obesity despite statistically significant differences in body fat percentage (BF%; healthy-weight children, 18.5 ± 6.1%; children with obesity, 41.1 ± 6.9%, p < .001) and aerobic capacity relative to body mass (VO 2 peak; healthy-weight children, 46.8 ± 8.2 mL/kg/min; children with obesity, 31.9 ± 4.7 mL/kg/min, p < .001). There were statistically significant differences in VO 2 recovery for the 5 min following exercise, Wilks's Lambda = .676, F(4, 26) = 3.117, p = .032. There were no statistically significant correlations between HRRec and body mass index (BMI), BF%, VO 2 peak, or physical activity. In a healthy pediatric population, obesity alone does not seem to significantly impact HRRec, and because HRRec was not related to obesity status, BMI, or BF%, it should not be used as the sole indicator of aerobic capacity or health status in children. Using more than one recovery variable (i.e., HRRec and VO 2 recovery) may provide greater insight into cardiorespiratory fitness in this population.

This study examined potential parenting-related mediators of children's physical activity and dietary behavior change in the Healthy Dads, Healthy Kids (HDHK) community program. A randomized controlled trial was conducted with 45 overweight/obese (mean [SD] age = 39.8 [5.4] years; BMI = 32.4 [3.8]) fathers and their children (n = 77; 58% boys; mean [SD] age = 7.7 [2.5] years). Families were randomized to either the HDHK program or wait-list control group. The program involved 7 sessions. Fathers and their children were assessed at baseline and at 14 weeks for physical activity (pedometery) and core food intake (Questionnaire). Fathers' lifestyle-related parenting practices included; self-efficacy, beliefs, modeling, logistic support, rules, cophysical activity, shared mealtime frequency and intentions. Significant intervention effects were found for cophysical activity and modeling physical activity. Cophysical activity mediated children's physical activity in the intervention ('mediated effect,' AB = 653, 95% CI = 4-2050) and was responsible for 59.5% of the intervention effect. Fathers' beliefs mediated children's percent energy from core foods (AB = 1.51, 95% CI = 0.05-5.55) and accounted for 72.9% of the intervention effect. Participation in the HDHK program positively impacted on fathers' cophysical activity with their child and beliefs about healthy eating which mediated changes in children's diet and physical activity behaviors.

Background: Adult height has shown directionally diverse associations with several age-related disorders, including cardiovascular disease, cancer, decline in cognitive function, and mortality. Objective: We investigated the associations of adult height with healthy aging measured by a full spectrum of health outcomes, including incidence of chronic diseases, memory, physical functioning, and mental health, among populations who have survived to older age, and whether lifestyle factors modified such relations. Design: We included 52,135 women (mean age: 44.2 y) from the Nurses' Health Study without chronic diseases in 1980 and whose health status was available in 2012. Healthy aging was defined as being free of 11 major chronic diseases and having no reported impairment of subjective memory, physical impairment, or mental health limitations. Results: Of all eligible study participants, 6877 (13.2%) were classified as healthy agers. After adjustment for demographic and lifestyle factors, we observed an 8% (95% CI: 6%, 11%) decrease in the odds of healthy aging per SD (0.062 m) increase in height. Compared with the lowest category of height (≤1.57 m), the OR of achieving healthy aging in the highest category (≥1.70 m) was 0.80 (95% CI: 0.73, 0.87; P -trend < 0.001). In addition, we found a significant interaction of height with a prudent dietary pattern in relation to healthy aging ( P -interaction = 0.005), and among the individual dietary factors characterizing the prudent dietary pattern, fruit and vegetable intake showed the strongest effect modification ( P -interaction = 0.01). The association of greater height with reduced odds of healthy aging appeared to be more evident among women with higher adherence to the prudent dietary pattern rich in vegetable and fruit intake. Conclusions: Greater height was associated with a modest decrease in the likelihood of healthy aging. A prudent diet rich in fruit and vegetables might modify the relation. © 2017

The link between brain structure and intelligence is a well-investigated topic, but existing analyses have mainly focused on adult samples. Studies in healthy children and adolescents are rare, and normative data specifically addressing the association between corpus callosum morphology and intellectual abilities is quite limited. To advance this field of research, we mapped the correlations between standardized intelligence measures and callosal thickness based on high-resolution magnetic resonance imaging (MRI) data. Our large and well-matched sample included 200 normally developing subjects (100 males, 100 females) ranging from 6 to 17 years of age. Although the strongest correlations were negative and confined to the splenium, the strength and the direction of intelligence-callosal thickness associations varied considerably with respect to age and sex. While significant correlations in females were mainly positive, significant correlations in males were exclusively negative. However, only the negative correlations in the overall sample (i.e., males and females combined) remained significant when controlling for multiple comparisons. The observed negative correlations between callosal thickness and intelligence in children and adolescents contrast with the positive correlations typically reported in adult samples. However, negative correlations are in line with reports from other pediatric studies relating cognitive measures to other brain attributes such as cortical thickness, gray matter volume, and gray matter density. Altogether, these findings suggest that relationships between callosal morphology and cognition are highly dynamic during brain maturation. Sex effects on links between callosal thickness and intelligence during childhood and adolescence are present but appear rather weak in general. PMID:20932920

Omega-3 fatty acids are dietary essentials, and the current low intakes in most modern developed countries are believed to contribute to a wide variety of physical and mental health problems. Evidence from clinical trials indicates that dietary supplementation with long-chain omega-3 may improve child behavior and learning, although most previous trials have involved children with neurodevelopmental disorders such as attention-deficit/hyperactivity disorder (ADHD) or developmental coordination disorder (DCD). Here we investigated whether such benefits might extend to the general child population. To determine the effects of dietary supplementation with the long-chain omega-3 docosahexaenoic acid (DHA) on the reading, working memory, and behavior of healthy schoolchildren. Parallel group, fixed-dose, randomized, double-blind, placebo-controlled trial (RCT). Mainstream primary schools in Oxfordshire, UK (n = 74). Healthy children aged 7-9 years initially underperforming in reading (≤ 33(rd) centile). 1376 invited, 362 met study criteria. 600 mg/day DHA (from algal oil), or taste/color matched corn/soybean oil placebo. Age-standardized measures of reading, working memory, and parent- and teacher-rated behavior. ITT analyses showed no effect of DHA on reading in the full sample, but significant effects in the pre-planned subgroup of 224 children whose initial reading performance was ≤ 20(th) centile (the target population in our original study design). Parent-rated behavior problems (ADHD-type symptoms) were significantly reduced by active treatment, but little or no effects were seen for either teacher-rated behaviour or working memory. DHA supplementation appears to offer a safe and effective way to improve reading and behavior in healthy but underperforming children from mainstream schools. Replication studies are clearly warranted, as such children are known to be at risk of low educational and occupational outcomes in later life. ClinicalTrials.gov NCT01066182

Body perception has been mainly studied in adolescents and adults in relation to eating disorders and obesity because such conditions are usually associated with distortion in the perception of body size. The development of body perception in children was rather neglected despite the relevance of this issue in understanding the aetiology of health eating problems. The main aim of this study was to investigate body weight and body height perception in children by gender, age and body mass index (BMI), taking into account differences among underweight, healthy weight, overweight and obese children. A school-based sample of 572 Italian children (49% boys) aged 6-10 were involved in a cross-sectional survey. Current weight and height were measured by standard protocols, and BMI was calculated and converted in centile categories using the Italian growth curves for children. Perceived weight and height were assessed using visual methods (figures representing children of different weight and height). About a third of the children do not show to have an accurate perception of their weight and height (weight: 36%; height: 32%): as for weight, an error of underestimation prevails and as for height, an error of overestimation prevails. In general, children who have different weight and height from the average tend to perceive their physical characteristics closer to average. However, overweight children underestimate their weight much more than obese children. Distortions in the perception of their physical features, weight and height, appear to be related to the aesthetic models of Western culture. The tendency to underestimate weight, particularly in overweight children, has implications in interventions for health promotion and healthy lifestyle in school-aged children. © 2014 John Wiley & Sons Ltd.

The structural isomer of asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA), is eliminated almost entirely by urinary excretion and considered a sensitive index of glomerular filtration rate (GFR). However, reports on this relationship in healthy subjects younger than 18 years of age are rare. Therefore, our aim was to investigate relations between endogenous dimethylarginines and renal function indices in healthy children and adolescents. We studied 40 subjects aged 3–18 years free of coexistent diseases or subclinical carotid atherosclerosis. A serum creatinine-derived estimated GFR (eGFR) was calculated by the revised bedside Schwartz equation. L-arginine, ADMA and SDMA were measured by liquid chromatography-tandem mass spectrometry. Mean eGFR was 122 ± 22 (SD) mL/min per 1.73 m2. Creatinine and eGFR exhibited closer correlations with the SDMA/ADMA ratio (r = 0.64, p < 0.0001; r = −0.63, p < 0.0001, respectively) than with SDMA (r = 0.31, p = 0.05; r = −0.35, p = 0.03). Neither creatinine nor eGFR correlated with ADMA or L-arginine. Adjustment for age or height only slightly attenuated the associations between the SDMA/ADMA ratio and eGFR or creatinine. Our findings suggest the superiority of the SDMA/ADMA ratio over SDMA as a renal function index in healthy children. Thus, further studies are warranted to verify our preliminary results in a larger group of subjects below 18 years of age.

Childhood obesity is a growing concern for public health. Given a majority of children in many countries spend approximately 30 h per week in early childcare centers, this environment represents a promising setting for implementing strategies to foster healthy behaviours for preventing and controlling childhood obesity. Healthy Start-Départ Santé was designed to promote physical activity, physical literacy, and healthy eating among preschoolers. The objectives of this study are to assess the effectiveness of the Healthy Start-Départ Santé intervention in improving physical activity levels, physical literacy, and healthy eating among preschoolers attending early childcare centers. This study follows a cluster randomized controlled trial design in which the childcare centers are randomly assigned to receive the intervention or serve as usual care controls. The Healthy Start-Départ Santé intervention is comprised of interlinked components aiming to enable families and educators to integrate physical activity and healthy eating in the daily lives of young children by influencing factors at the intrapersonal, interpersonal, organizational, community, physical environment and policy levels. The intervention period, spanning 6-8 months, is preceded and followed by data collections. Participants are recruited from 61 childcare centers in two Canadian provinces, New Brunswick and Saskatchewan. Centers eligible for this study have to prepare and provide meals for lunch and have at least 20 children between the ages of 3 and 5. Centers are excluded if they have previously received a physical activity or nutrition promoting intervention. Eligible centers are stratified by province, geographical location (urban or rural) and language (English or French), then recruited and randomized using a one to one protocol for each stratum. Data collection is ongoing. The primary study outcomes are assessed using accelerometers (physical activity levels), the Test of Gross Motor

Background: As medication does not normalize outcomes of children with attention deficit hyperactivity disorder (ADHD), especially in real-life functioning, nonpharmacological methods are important to target this field. This randomized controlled clinical trial was designed to evaluate the effects of a comprehensive executive skill training program for school-aged children with ADHD in a relatively large sample. Methods: The children (aged 6–12 years) with ADHD were randomized to the intervention or waitlist groups. A healthy control group was composed of gender- and age-matched healthy children. The intervention group received a 12-session training program for multiple executive skills. Executive function (EF), ADHD symptoms, and social functioning in the intervention and waitlist groups were evaluated at baseline and the end of the final training session. The healthy controls (HCs) were only assessed once at baseline. Repeated measures analyses of variance were used to compare EF, ADHD symptoms, and social function between intervention and waitlist groups. Results: Thirty-eight children with ADHD in intervention group, 30 in waitlist group, and 23 healthy children in healthy control group were included in final analysis. At posttreatment, intervention group showed significantly lower Behavior Rating Inventory of Executive Function (BRIEF) total score (135.89 ± 16.80 vs. 146.09 ± 23.92, P = 0.04) and monitoring score (18.05 ± 2.67 vs. 19.77 ± 3.10, P = 0.02), ADHD-IV overall score (41.11 ± 7.48 vs. 47.20 ± 8.47, P < 0.01), hyperactivity-impulsivity (HI) subscale score (18.92 ± 5.09 vs. 21.93 ± 4.93, P = 0.02), and inattentive subscale score (22.18 ± 3.56 vs. 25.27 ± 5.06, P < 0.01), compared with the waitlist group. Repeated measures analyses of variance revealed significant interactions between time and group on the BRIEF inhibition subscale (F = 5.06, P = 0.03), working memory (F = 4.48, P = 0.04), ADHD-IV overall score (F = 21.72, P < 0.01), HI

To evaluate the outcomes among critically ill young children with Down syndrome using propensity score matching from a national database. Patients in the age group from one day through 24 months admitted to an intensive care unit during their hospital stay at a Pediatric Health Information System (PHIS)-participating hospital (2004-2013) were included. Of the 293,697 patients who qualified for inclusion, 12,282 (4%) were classified in the Down syndrome group. Using propensity score matching, 10,477 patients with Down syndrome were matched one to one to patients without Down syndrome. Prior to matching, the mortality was significantly lower among the patients with Down syndrome (with vs. without Down syndrome, odds ratio (OR), 0.74; 95% confidence interval (CI), 0.69-0.79; p < 0.001). After matching, the mortality was similar in both groups (OR, 0.96; 95% CI, 0.87-1.07; p = 0.51). The mortality risk increased among the Down syndrome patients with increasing hospital length of stay (LOS). In this large, contemporary cohort, Down syndrome did not confer a significantly higher mortality risk among children with critical illness. However, children with Down syndrome followed a time-dependent, differential mortality risk with increased risk noted in relation to increasing hospital LOS. ©2015 Foundation Acta Paediatrica.

Quality of life (QoL) as it is related with growth hormone deficiency (GHD) is a matter of controversy. We analyzed QoL in 95 children aged 8-18 years with isolated GHD (72% male) treated with growth hormone (GH). These children were compared to 190 age- and gender-matched healthy children with similar height [height <10th percentile; control group 1 (CG1)] and age- and gender-matched 285 healthy children of normal stature (control group 2: CG2). QoL was measured by the KINDL® questionnaire referring to six domains (physical well-being, emotional well-being, self-esteem, family, friends, and school). QoL was significantly reduced in CG1 (effect-size 0.21) compared to CG2, while QoL was not significantly altered in children with GHD. In multiple linear regression analyses adjusted to age, gender, BMI, migration background, and socioeconomic status, decreasing height-SDS was associated with poorer QoL (especially emotional well-being), and treatment with GH was related significantly to better self-esteem. Increase of height-SDS in children treated with GH was associated positively with QoL and all its subscales except family and school. These findings suggest psychological consequences of short stature in children and an improvement of QoL in children treated with GH with the focus on self-esteem and emotional well-being.

Studies of long-lived individuals have revealed few genetic mechanisms for protection against age-associated disease. Therefore, we pursued genome sequencing of a related phenotype-healthy aging-to understand the genetics of disease-free aging without medical intervention. In contrast with studies of exceptional longevity, usually focused on centenarians, healthy aging is not associated with known longevity variants, but is associated with reduced genetic susceptibility to Alzheimer and coronary artery disease. Additionally, healthy aging is not associated with a decreased rate of rare pathogenic variants, potentially indicating the presence of disease-resistance factors. In keeping with this possibility, we identify suggestive common and rare variant genetic associations implying that protection against cognitive decline is a genetic component of healthy aging. These findings, based on a relatively small cohort, require independent replication. Overall, our results suggest healthy aging is an overlapping but distinct phenotype from exceptional longevity that may be enriched with disease-protective genetic factors. VIDEO ABSTRACT.

The cost of community-managed viral respiratory illnesses in a cohort of healthy preschool-aged children

PubMed Central

Lambert, Stephen B; Allen, Kelly M; Carter, Robert C; Nolan, Terence M

2008-01-01

Background Acute respiratory illnesses (ARIs) during childhood are often caused by respiratory viruses, result in significant morbidity, and have associated costs for families and society. Despite their ubiquity, there is a lack of interdisciplinary epidemiologic and economic research that has collected primary impact data, particularly associated with indirect costs, from families during ARIs in children. Methods We conducted a 12-month cohort study in 234 preschool children with impact diary recording and PCR testing of nose-throat swabs for viruses during an ARI. We used applied values to estimate a virus-specific mean cost of ARIs. Results Impact diaries were available for 72% (523/725) of community-managed illnesses between January 2003 and January 2004. The mean cost of ARIs was AU$309 (95% confidence interval $263 to $354). Influenza illnesses had a mean cost of $904, compared with RSV, $304, the next most expensive single-virus illness, although confidence intervals overlapped. Mean carer time away from usual activity per day was two hours for influenza ARIs and between 30 and 45 minutes for all other ARI categories. Conclusion From a societal perspective, community-managed ARIs are a significant cost burden on families and society. The point estimate of the mean cost of community-managed influenza illnesses in healthy preschool aged children is three times greater than those illnesses caused by RSV and other respiratory viruses. Indirect costs, particularly carer time away from usual activity, are the key cost drivers for ARIs in children. The use of parent-collected specimens may enhance ARI surveillance and reduce any potential Hawthorne effect caused by compliance with study procedures. These findings reinforce the need for further integrated epidemiologic and economic research of ARIs in children to allow for comprehensive cost-effectiveness assessments of preventive and therapeutic options.

Objectives To evaluate pedestrian behavior, including reaction time, impulsivity, risk-taking, attention, and decision-making, in children with obstructive sleep apnea syndrome (OSAS) compared with healthy controls. Study design Using a case control design, sixty 8- to 16-year-olds with newly diagnosed and untreated OSAS engaged in a virtual reality pedestrian environment. Sixty-one healthy children matched using a yoke-control procedure by age, race, gender and household income served as controls. Results Children with OSAS were riskier pedestrians than healthy children of the same age, race, and sex. Children with OSAS waited less time to cross (p<.01). The groups did not differ in looking at oncoming traffic or taking longer to decide to cross. Conclusions Results suggest OSAS may have significant consequences on children’s daytime functioning in a critical domain of personal safety, pedestrian skills. Children with OSAS appeared to have greater impulsivity when crossing streets. Results highlight the need for heightened awareness of the consequences of untreated sleep disorders and identify a possible target for pediatric injury prevention. PMID:25444002

To assess whether exposure to high altitude induces cognitive dysfunction in young healthy European children and adolescents during acute, short-term exposure to an altitude of 3450 m and in an age-matched European population permanently living at this altitude. We tested executive function (inhibition, shifting, and working memory), memory (verbal, short-term visuospatial, and verbal episodic memory), and speed processing ability in: (1) 48 healthy nonacclimatized European children and adolescents, 24 hours after arrival at high altitude and 3 months after return to low altitude; (2) 21 matched European subjects permanently living at high altitude; and (3) a matched control group tested twice at low altitude. Short-term hypoxia significantly impaired all but 2 (visuospatial memory and processing speed) of the neuropsychological abilities that were tested. These impairments were even more severe in the children permanently living at high altitude. Three months after return to low altitude, the neuropsychological performances significantly improved and were comparable with those observed in the control group tested only at low altitude. Acute short-term exposure to an altitude at which major tourist destinations are located induces marked executive and memory deficits in healthy children. These deficits are equally marked or more severe in children permanently living at high altitude and are expected to impair their learning abilities. Copyright © 2016 Elsevier Inc.

This study examines the cognitive functioning of parents of children with disabilities, specifically, whether there is an evidence of accelerated cognitive aging among these parents. In addition, the study investigates the moderating influences of two variables: parents' gender and stress from negative parenting experience. The analyses utilize data from the National Survey of Midlife in the United States (2005). The analytic sample consisted of two groups of parents, who completed the cognitive battery, the interview, and the mail-back survey: 128 parents who had children with childhood-onset disabilities and 512 matched comparison parents who had only nondisabled children. Age differences in episodic memory were more pronounced among mothers of children with disabilities than among mothers with nondisabled children, especially among mothers with higher levels of negative parenting experience. In contrast, there were no interaction effects of parenting status, age, and negative parenting experience among fathers. The results show that parenting children with disabilities over a prolonged period of time jeopardizes cognitive function (especially memory) among older mothers, possibly via the mechanism of heightened parenting stress due to higher levels of negative parenting experience. © The Author 2015.

To present a method for age-matched deviation mapping in the assessment of disease-related changes to the radial peripapillary capillaries (RPCs). We reviewed 4.5x4.5mm en face peripapillary OCT-A scans of 133 healthy control eyes (133 subjects, mean 41.5 yrs, range 11-82 yrs) and 4 eyes with distinct retinal pathologies, obtained using spectral-domain optical coherence tomography angiography. Statistical analysis was performed to evaluate the impact of age on RPC perfusion densities. RPC density group mean and standard deviation maps were generated for each decade of life. Deviation maps were created for the diseased eyes based on these maps. Large peripapillary vessel (LPV; noncapillary vessel) perfusion density was also studied for impact of age. Average healthy RPC density was 42.5±1.47%. ANOVA and pairwise Tukey-Kramer tests showed that RPC density in the ≥60yr group was significantly lower compared to RPC density in all younger decades of life (p<0.01). Average healthy LPV density was 21.5±3.07%. Linear regression models indicated that LPV density decreased with age, however ANOVA and pairwise Tukey-Kramer tests did not reach statistical significance. Deviation mapping enabled us to quantitatively and visually elucidate the significance of RPC density changes in disease. It is important to consider changes that occur with aging when analyzing RPC and LPV density changes in disease. RPC density, coupled with age-matched deviation mapping techniques, represents a potentially clinically useful method in detecting changes to peripapillary perfusion in disease.

This study aimed to use bioelectrical impedance analysis (BIA) to generate a new muscle density index (MDI), the MDI_BIA, to evaluate muscle development, and to demonstrate the changes that occur in the BIA-based muscle cross-sectional area index (MCAI_BIA) that accompany growth. We also sought to determine the traceability of chronological changes in the MDI_BIA and MCAI_BIA. Healthy children (n=112) aged 8.68±3.16years (0.33-14.00years) underwent bioelectrical impedance (BI) measurements of their upper arms, thighs, and lower legs. The MDI_BIA and MCAI_BIA were calculated, and cross-sectional investigations were conducted into the changes in these indices that accompanied growth. Data collected after 1.10±0.08years from 45 participants determined the traceability of the chronological changes in the MDI_BIA and MCAI_BIA. The MDI_BIA and MCAI_BIA were significantly positively correlated with age and height at all locations (P<0.01). The relationships between the locations and the MDI_BIA and MCAI_BIA differed, indicating that these indices evaluated the muscles from different perspectives. Except for the upper arm MDI_BIA, both indices at all locations regardless of age, showed significant chronological increases after an average period of 1.10years. The MDI_BIA and MCAI_BIA were significantly correlated with age and height in healthy children, and they showed significant chronological increases. Hence, these indices could be used to represent muscle development and muscle mass increases. BIA is non-invasive, convenient, and economical and it may be useful in evaluating muscle development and muscle cross-sectional areas in children.

It is critical to promote healthy eating early in life. The aim of this study was to examine diet quality and its predictors among Australian preschool-aged children. Diet was assessed at age 3.5 years using multiple 24-hour recalls. Diet quality was assessed using an adapted version of the Revised Children's Diet Quality Index (RC-DQI). Potential predictors of diet quality were from questionnaires at age 3, 9, and 18 months and informed by the ecologic model of childhood overweight. Potential predictors included child's sex, age of introduction to solid foods, breastfeeding status, food acceptance, maternal nutrition knowledge, modeling of healthy eating, self-efficacy, education, and home food availability. Data from 244 children participating in the Melbourne Infant Feeding, Activity, and Nutrition Trial in 2008-2010 and follow-up data collection in 2011-2013 were examined. Diet quality at age 3.5 years. Bivariate logistic regression was performed to assess the relationship between diet quality and each predictor. A multivariable logistic regression model accounting for influences of covariates, treatment arm, and clustering by group tested associations between diet quality and significant predictors from bivariate analyses. RC-DQI scores had a mean±standard deviation score of 62.8±8.3 points out of a maximum of 85 points. Breastfeeding status (odds ratio [OR] 2.34, 95% CI 1.33 to 4.10) and maternal modeling of healthy eating (OR 1.75, 95% CI 1.01 to 3.03) were positively associated with RC-DQI scores. Both breastfeeding status (OR 3.09, 95% CI 1.63 to 5.85) and modeling (OR 2.01, 95% CI 1.04 to 3.88) remained positively associated with diet quality after adjustment for child age, body mass index z score, energy intake, treatment arm, and clustering. Breastfeeding status and modeling of healthy eating were independently associated with children's diet quality. Early intervention could assist mothers to practice these behaviors to provide support for improving

Age-related reference intervals (RIs) of aortic pulse wave velocity (Ao-PWV) obtained from a large healthy population are lacking in South America. The aims of this study were to determine Ao-PWV RIs in a cohort of healthy children and adolescents from Argentina and to generate year-to-year percentile curves. Ao-PWV was measured in 1000 healthy subjects non-exposed to traditional cardiovascular risk factors (Age: 10-22 y. o., 56% males). First, we evaluated if RIs for males and females were necessaries (correlation and covariate analysis). Second, mean (M) and standard deviation (SD) age-related equations were obtained for cf-PWV, using parametric regression methods based on fractional polynomials. Third, age-specific (year to year) percentiles curves (for all, males and females children and adolescents) were generated using the standard normal distribution. They were, age-specific 1st, 2.5th, 5th, 10th, 25th, 50th, 75th, 90th, 95th, 97.5th and 99th percentile curves and values. After covariate analysis (i.e., adjusting by age, jugulum-symphysis distance, body weight and height), specific RIs for males and females of children and adolescents were evidenced as necessaries. The equations were For all subjects: Ao-PWV_Mean = 4.98 + 12.86x10 -5 Age 3 . Ao-PWV_SD = 0.47 + 21.00x10 -6 Age 3 . For girls: Ao-PWV_Mean = 5.07 + 10.23x10 -5 Age 3 . Ao-PWV_SD = 0.50 + 10.00x10 -6 Age 3 . For boys: Ao-PWV_Mean = 4.87 + 15.81x10 -5 Age 3 . Ao-PWV_SD = 0.46 + 22.34x10 -6 Age 3 . Our study provides the largest database to-date concerning Ao-PWV in healthy children and adolescents in Argentina. Age-related equations (M and SD values) for Ao-PWV are reported by the first time. Specific RIs and percentiles of Ao-PWV are now available according to age and sex for an Argentinian population.

To describe the distribution of hs-cTnI in a large cohort of healthy children. As part of the LOOK study, blood was collected from a large cohort of healthy children on 3 separate occasions when the children were aged 8, 10 and 12years. Samples were stored at -80°C after collection and assayed after 1 freeze-thaw cycle using a pre-commercial release hs-cTnI assay from Abbott Diagnostics. More than 98% of the 12year-old children had cTnI above the LoD of 1.0ng/L. For the 212 boys the central 95% of results was distributed in a Gaussian fashion. For the 237 girls, the initial analysis was non-Gaussian, but after the elimination of 2 results, the pattern for girls was also Gaussian. In healthy children, cTnI is present in a Gaussian distribution. Even minor illnesses can cause some troponin release, distorting this Gaussian distribution. Copyright © 2012 Elsevier B.V.

To examine the relationship between acquisition of fine motor skills in childhood and development of the motor cortex. We measured finger tapping speed and mirror movements in 43 healthy right-handed subjects (6-26 years of age). While recording surface electromyographic activity from right and left first dorsal interosseus, we delivered focal transcranial magnetic stimulation (TMS) over the hand areas of each motor cortex. We measured motor evoked potential (MEP) threshold, and ipsilateral (iSP) and contralateral (CSP) silent periods. As children got older, finger speeds got faster, MEP threshold decreased, iSP duration increased and latency decreased. Finger tapping speed got faster as motor thresholds and iSP latency decreased, but was unrelated to CSP duration. In all subjects right hemisphere MEP thresholds were higher than those on the left and duration of right hemisphere CSP was longer than that on the left. Children under 10 years of age had higher left hand mirror movement scores, and fewer left hemisphere iSPs which were of longer duration. Maturation of finger tapping skills is closely related to developmental changes in the motor threshold and iSP latency. Studies are warranted to explore the relationship between these measures and other neuromotor skills in children with motor disorders. TMS can provide important insights into certain functional aspects of neurodevelopment in children.

In children who are born small for gestational age (SGA), an adverse intrauterine environment has led to underdevelopment of both the body and the brain. The delay in body growth is (partially) restored during the first two years in a majority of these children. In addition to a negative influence on these physical parameters, decreased levels of intelligence and cognitive impairments have been described in children born SGA. In this study, we used magnetic resonance imaging to examine brain anatomy in 4- to 7-year-old SGA children with and without complete bodily catch-up growth and compared them to healthy children born appropriate for gestational age. Our findings demonstrate that these children strongly differ on brain organisation when compared with healthy controls relating to both global and regional anatomical differences. Children born SGA displayed reduced cerebral and cerebellar grey and white matter volumes, smaller volumes of subcortical structures and reduced cortical surface area. Regional differences in prefrontal cortical thickness suggest a different development of the cerebral cortex. SGA children with bodily catch-up growth constitute an intermediate between those children without catch-up growth and healthy controls. Therefore, bodily catch-up growth in children born SGA does not implicate full catch-up growth of the brain. PMID:21931650

Numerous studies show higher cough reflex sensitivity (CRS) and cough outcomes in children compared to adults and in females compared to males. Despite close link that exists between cough and environment the potential influence of environmental air pollution on age- and gender -related differences in cough has not been studied yet. The purpose of our study was to analyse whether the effects of exposure to environmental tobacco smoke (ETS) from parental smoking and PM10 from living in urban area are implied in age- and gender-related differences in cough outcomes of healthy, non-asthmatic children. Assessment of CRS using capsaicin and incidence of dry and wet cough was performed in 290 children (mean age 13.3 ± 2.6 years (138 females/152 males). CRS was significantly higher in girls exposed to ETS [22.3 μmol/l (9.8-50.2 μmol/l)] compared to not exposed girls [79.9 μmol/l (56.4-112.2 μmol/l), p = 0.02] as well as compared to exposed boys [121.4 μmol/l (58.2-253.1 μmol/l), p = 0.01]. Incidence of dry cough lasting more than 3 weeks was significantly higher in exposed compared to not exposed girls. CRS was significantly higher in school-aged girls living in urban area [22.0 μmol/l (10.6-45.6 μmol/l)] compared to school-aged girls living in rural area [215.9 μmol/l (87.3-533.4 μmol/l); p = 0.003], as well as compared to teenage girls living in urban area [108.8 μmol/l (68.7-172.9 μmol/l); p = 0.007]. No CRS differences were found between urban and rural boys when controlled for age group. No CRS differences were found between school-aged and teenage boys when controlled for living area. Our results have shown that the effect of ETS on CRS was gender specific, linked to female gender and the effect of PM10 on CRS was both gender and age specific, related to female gender and school-age. We suggest that age and gender related differences in incidence of cough and CRS might be, at least partially, ascribed to the effect of environmental pollutants. The role

Micronutrients are important in physical work capacity and therefore performance. The impact of a multi-micronutrient-fortified nutritional beverage on physical performance measures among clinically healthy school-age children was assessed in a double-blind (for test and placebo groups), placebo-controlled, randomized trial in children aged between 7 and 10.5 y (n = 300). The participants with height- and weight-for-age Z-scores between 0 and ≥ -3 were randomized to 1 of 3 study arms: fortified choco-malt beverage powder (F), matched energy equivalent unfortified placebo (U), and untreated control (C). Participants in the F and C groups were given 40 g fortified (19 key vitamins and minerals) and unfortified choco-malt beverage, respectively, daily for 120 d. Primary efficacy outcomes included endurance and aerobic capacity using a 20-m shuttle test and step test. Other physical performance measures included speed (40-m sprint), visual reaction time, maximal hand grip, and forearm static endurance. Micronutrient status included thiamin, riboflavin, folate, niacin, iron, pyridoxal phosphate, and vitamins B-12 and C. All measurements were made at baseline and the end of the intervention. There was a within-subject increase in aerobic capacity and whole body endurance (P < 0.05) accompanied by a significant improvement in the status of iron thiamin, riboflavin, pyridoxal phosphate, folate, and vitamins C and B-12 in the F group compared to the within-subject changes in the other 2 groups (P < 0.05). The study suggests that multiple micronutrient supplementation in similar populations may be beneficial in improving micronutrient status and enhancing aerobic capacity and endurance in children.

This exploratory study aims at investigating the effects of terrorism on children's ability to recognize emotions. A sample of 101 exposed and 102 nonexposed children (mean age = 11 years), balanced for age and gender, were assessed 20 months after a terrorist attack in Beslan, Russia. Two trials controlled for children's ability to match a facial emotional stimulus with an emotional label and their ability to match an emotional label with an emotional context. The experimental trial evaluated the relation between exposure to terrorism and children's free labeling of mixed emotion facial stimuli created by morphing between 2 prototypical emotions. Repeated measures analyses of covariance revealed that exposed children correctly recognized pure emotions. Four log-linear models were performed to explore the association between exposure group and category of answer given in response to different mixed emotion facial stimuli. Model parameters indicated that, compared with nonexposed children, exposed children (a) labeled facial expressions containing anger and sadness significantly more often than expected as anger, and (b) produced fewer correct answers in response to stimuli containing sadness as a target emotion.

Limited evidence suggests that female breast tissue ages faster than other parts of the body according to an epigenetic biomarker of aging known as the "epigenetic clock." However, it is unknown whether breast tissue samples from healthy women show a similar accelerated aging effect relative to other tissues, and what could drive this acceleration. The goal of this study is to validate our initial finding of advanced DNA methylation (DNAm) age in breast tissue, by directly comparing it to that of peripheral blood tissue from the same individuals, and to do a preliminary assessment of hormonal factors that could explain the difference. We utilized n = 80 breast and 80 matching blood tissue samples collected from 40 healthy female participants of the Susan G. Komen Tissue Bank at the Indiana University Simon Cancer Center who donated these samples at two time points spaced at least a year apart. DNA methylation levels (Illumina 450K platform) were used to estimate the DNAm age. DNAm age was highly correlated with chronological age in both peripheral blood (r = 0.94, p < 0.0001) and breast tissues (r = 0.86, p < 0.0001). A measure of epigenetic age acceleration (age-adjusted DNAm Age) was substantially increased in breast relative to peripheral blood tissue (p = 1.6 × 10 -11 ). The difference between DNAm age of breast and blood decreased with advancing chronologic age (r = -0.53, p = 4.4 × 10 -4 ). Our data clearly demonstrate that female breast tissue has a higher epigenetic age than blood collected from the same subject. We also observe that the degree of elevation in breast diminishes with advancing age. Future larger studies will be needed to examine associations between epigenetic age acceleration and cumulative hormone exposure.

We determined flow rates and generated flow rate-voided volume nomograms based on healthy children 5 to 15 years old voiding spontaneously in their natural environment. A total of 824 healthy school children of both genders were enrolled. A single uroflow record from each child was evaluated. A total of 103 children with a voided volume of less than 50 ml and/or a staccato/interrupted uroflow pattern were excluded, and 721 records were analyzed. Data were evaluated using several mathematical formulas and goodness of fit was determined. Linear regression analysis was used to generate nomograms. Flow rates and voided volumes increased with increasing age, with the effect being more pronounced in girls. No significant difference was noted in uroflow rates from 5 to 10 years, but significant differences (p <0.001) started appearing at 11 to 15 years. Also no significant difference was noted in uroflow rates among children 11 to 15 years. Therefore, 2 age groups were designated, with group 1 consisting of patients 5 to 10 years old and group 2 consisting of patients 11 to 15 years old. There were 222 boys and 122 girls in group 1 and 240 boys and 137 girls in group 2. In group 1 the maximum and average ± SD flow rates were 15.26 ± 4.54 ml per second and 7.68 ± 3.26 ml per second, respectively, for boys and 17.98 ± 6.06 ml per second and 9.19 ± 4.23 ml per second, respectively, for girls. In group 2 these rates were 22.50 ± 7.24 ml per second and 10.78 ± 4.03 ml per second, respectively, for boys and 27.16 ± 9.37 ml per second and 13.48 ± 5.21 ml per second, respectively, for girls. This large study, which expands the scant existing literature on uroflow parameters in healthy children, will hopefully promote wider application of uroflowmetry testing in the pediatric population.

To evaluate the impact of a family-oriented inpatient rehabilitation programme on behavioural and emotional problems in healthy siblings of chronically ill children and to assess the association between these problems and quality of life. A total of 259 healthy children (4-16 years, M = 8.6 years, SD = 3.3) with a chronically ill sibling were enrolled in the study. Parents filled in the Strengths and Difficulties Questionnaire, while the children answered a self-report quality of life instrument (LQ-KID) at the time of admission and discharge from the clinic and at a 6-month follow-up. Comparisons were performed with a matched control group from the German general population (n= 777). Significant behavioural or emotional symptoms were found in 30.5% of the healthy siblings, the relative risk of having elevated scores being 2.2 compared with the control group. Symptoms were inversely correlated with quality of life (r=-0.42). During the inpatient rehabilitation, symptoms decreased significantly to a normal level. Similarly, quality of life significantly improved, except in the dimension family relations. Family-oriented inpatient rehabilitation is a promising approach to improve the mental health of children with a chronically ill sibling.

Being severely overweight is a distinctive clinical feature of Prader-Willi Syndrome (PWS). PWS is a complex multisystem disorder, representing the most common form of genetic obesity. The aim of this study was the analysis of the gait pattern of adult subjects with PWS by using three-Dimensional Gait Analysis. The results were compared with those obtained in a group of obese patients and in a group of healthy subjects. Cross-sectional, comparative study: 19 patients with PWS (11 males and 8 females, age: 18-40 years, BMI: 29.3-50.3 kg/m2); 14 obese matched patients (5 males and 9 females, age: 18-40 years, BMI: 34.3-45.2 kg/m2); 20 healthy subjects (10 males and 10 females, age: 21-41 years, BMI: 19.3-25.4 kg/m2). Kinematic and kinetic parameters during walking were assessed by an optoelectronic system and two force platforms. PWS adult patients walked slower, had a shorter stride length, a lower cadence and a longer stance phase compared with both matched obese, and healthy subjects. Obese matched patients showed spatio-temporal parameters significantly different from healthy subjects.Furthermore, Range Of Motion (ROM) at knee and ankle, and plantaflexor activity of PWS patients were significantly different between obese and healthy subjects. Obese subjects revealed kinematic and kinetic data similar to healthy subjects. PWS subjects had a gait pattern significantly different from obese patients. Despite that, both groups had a similar BMI. We suggest that PWS gait abnormalities may be related to abnormalities in the development of motor skills in childhood, due to precocious obesity. A tailored rehabilitation program in early childhood of PWS patients could prevent gait pattern changes.

The present study describes a tactual object matching task based on the study of Lederman and Klatzky (1987) for the dimensions Exact shape, Weight, Volume and Texture. Participants were congenitally blind children and their sighted classmates, congenitally blind adults and sighted adults. To study a possible effect of familiarity the task was performed four times. Based on Millar's CAPIN (Convergent Active Processes in Interrelated Networks) model of spatial processing (Millar, 1994) it was thought that this manipulation would add redundant information to the experiment from which the children and blind participants could benefit. The results showed that accuracy was affected more by age than visual status, especially for the dimension Exact Shape. With regard to response times, children were in most cases faster than adults, especially the sighted adults. Familiarization had a significant effect on response times for all dimensions. Extra exercise only increased accuracy for the dimension Texture. These results were generally in line with the CAPIN model. Copyright © 2011 Elsevier B.V. All rights reserved.

Do parents of obese children use ineffective parenting strategies?

PubMed

Morawska, Alina; West, Felicity

2013-12-01

Research has shown mixed findings about the relationship between parenting style and child lifestyle outcomes. This paper describes a cross-sectional study that aimed to clarify the relationship between ineffective parenting and childhood obesity by using multiple measures of child and family functioning. Sixty-two families with an obese child (aged four to 11 years) were matched with 62 families with a healthy weight child on key sociodemographic variables. Significant differences were found on several measures, including general parenting style, domain-specific parenting practices, and parenting self-efficacy (d = .53 to 1.96). Parents of obese children were more likely to use permissive and coercive discipline techniques, and to lack confidence in managing children's lifestyle behaviour. In contrast, parents of healthy weight children were more likely to implement specific strategies for promoting a healthy lifestyle.

Low serum 25-hydroxyvitamin D [25(OH)D] has been associated with unfavorable cardiometabolic risk profiles in many observational studies in children, but very few randomized controlled trials have investigated this. We explored the effect of winter-time cholecalciferol (vitamin D3) supplementation on cardiometabolic risk markers in young, white, 4- to 8-y-old healthy Danish children (55°N) as part of the pan-European ODIN project. In the ODIN Junior double-blind, placebo-controlled, dose-response trial, 119 children (mean ± SD age: 6.7 ± 1.5 y; 36% male; 82% normal weight) were randomly allocated to 0, 10 or 20 µg/d of vitamin D3 for 20 wk (October-March). Cardiometabolic risk markers including BMI-for-age z score (BMIz), waist circumference, systolic and diastolic blood pressure, serum triglycerides and cholesterol (total, LDL, HDL, and total:HDL), plasma glucose and insulin, and whole-blood glycated hemoglobin were measured at baseline and endpoint as secondary outcomes together with serum 25(OH)D. Intervention effects were evaluated in linear regression models as between-group differences at endpoint adjusted for baseline value of the outcome, and additionally for age, sex, baseline serum 25(OH)D, BMIz, time since breakfast, and breakfast content. Mean ± SD serum 25(OH)D was 56.7 ± 12.3 nmol/L at baseline and differed between groups at endpoint with concentrations of 31.1 ± 7.5, 61.8 ± 10.6, and 75.8 ± 11.5 nmol/L in the 0-, 10-, and 20 µg/d groups, respectively (P < 0.0001). Vitamin D3 supplementation had no effect on any of the cardiometabolic risk markers in analyses adjusted for baseline value of the outcome (all P ≥ 0.05), and additional covariate adjustment did not change the results notably. Preventing the winter decline in serum 25(OH)D with daily vitamin D3 supplementation of 10 or 20 µg had no cardiometabolic effects in healthy 4- to 8-y-old Danish children. This trial was registered at www.clinicaltrials.gov as NCT02145195.

Previous studies have shown that children learning alphabetic writing systems who have language impairment or dyslexia exhibit speech perception deficits. However, whether such deficits exist in children learning logographic writing systems who have poor reading comprehension remains uncertain. To further explore this issue, the present study examined speech perception deficits in Mandarin-speaking children with poor reading comprehension. Two self-designed tasks, consonant categorical perception task and lexical tone discrimination task were used to compare speech perception performance in children (n = 31, age range = 7;4–10;2) with poor reading comprehension and an age-matched typically developing group (n = 31, age range = 7;7–9;10). Results showed that the children with poor reading comprehension were less accurate in consonant and lexical tone discrimination tasks and perceived speech contrasts less categorically than the matched group. The correlations between speech perception skills (i.e., consonant and lexical tone discrimination sensitivities and slope of consonant identification curve) and individuals’ oral language and reading comprehension were stronger than the correlations between speech perception ability and word recognition ability. In conclusion, the results revealed that Mandarin-speaking children with poor reading comprehension exhibit less-categorized speech perception, suggesting that imprecise speech perception, especially lexical tone perception, is essential to account for reading learning difficulties in Mandarin-speaking children.

McPherson, Amy C; Lindsay, Sally

2012-07-01

Childhood obesity is one of the greatest health problems of the 21st Century. Compared with their non-disabled peers, children with disabilities have been shown to be at higher risk of obesity and associated secondary conditions which can hinder independence and community participation. Health promotion initiatives for children are rarely tailored to those with disabilities, and children may have different perceptions of health and well-being than those without disabilities. These need to be understood for future health promotion programs to be effective. This pilot study explored how children with disabilities perceive health and well-being and involved four discussion groups with children who were currently inpatients at a children's rehabilitation hospital. Descriptive thematic analysis was used. Fourteen children (eight girls, six boys; aged 8-13 years) with a range of congenital and acquired conditions participated in one of four discussion groups. There was an awareness of "healthy living" behaviors, nutrition and exercise examples being most commonly cited, although participants particularly discussed "unhealthy" food preferences. Physical capabilities, both before their hospital stay and their expectations for future activities, were also prominent. Although children in this study had some basic understanding of healthy nutrition, it was not easily translated to their own food choices. Children may need assistance to engage in rewarding physical activities within the constraints of their disability. Copyright © 2012 Elsevier Inc. All rights reserved.

B12 absorption was investigated in 47 healthy children aged 7 months to 15.8 years (median 4.9 years). The patients had either recovered from giardiasis, the post-gastroenteritis syndrome, or had celiac disease in remission (treated with a gluten-free diet). The B12 absorption was measured by a double-isotope technique using /sup 57/CoB12 and /sup 51/CrCl/sub 3/, the latter being the inabsorbable marker. The radiation dose was minimal. The results were presented as fractional absorption of B12 (FAB12). Within the different age groups, the absorption test was performed by means of the following oral amounts of B12: 0- less than 1 year, 0.5more » microgram; 1-3 years: 1.7 micrograms, 4-6 years, 2.5 micrograms; 7-10 years; 3.3 micrograms; and 11-15 years, 4.5 micrograms. When using these oral amounts of B12, the medians (and ranges) of FAB12 were found to be: 1-3 years (n = 18), 37% (16-80%); 4-6 years (n = 10), 27% (19-40%); 7-10 years (n = 9), 32% (21-44%); and 11-15 years (n = 8), 27% (19-59%). The FAB12 in two children aged 7 and 11 months was 31% and 32%, respectively. These results may be interpretated as reference values for B12 absorption in children. Further absorption tests were performed in seven children representing the four age groups from 1 to 15 years. When a high oral amount of B12 was given (i.e., three times the saturation dose), the FAB12 ranged from 0 to 20% (median 9%), whereas a low amount (i.e., one-ninth of the saturation dose) produced fractional absorptions from 65 to 82% (median 74%).« less

Sickle cell disease (SCD) is an inherited blood disorder associated with significant morbidity, which includes severe episodic pain, and, often, chronic pain. Compared to healthy individuals, patients with SCD report enhanced sensitivity to thermal detection and pain thresholds and have altered inflammatory profiles, yet no studies to date have examined biomarker reactivity after laboratory-induced pain. We sought to examine this relationship in patients with SCD compared to healthy control participants. We completed quantitative sensory testing in 83 patients with SCD and sequential blood sampling in 27 of them, whom we matched (sex, age, race, body mass index, and education) to 27 healthy controls. Surprisingly, few quantitative sensory testing differences emerged between groups. Heat pain tolerance, pressure pain threshold at the trapezius, thumb, and quadriceps, and thermal temporal summation at 45°C differed between groups in the expected direction, whereas conditioned pain modulation and pain ratings to hot water hand immersion were counterintuitive, possibly because of tailoring the water temperature to a perceptual level; patients with SCD received milder temperatures. In the matched subsample, group differences and group-by-time interactions were observed in biomarkers including tumor necrosis factor alpha, interleukin-1ß, interleukin-4, and neuropeptide Y. These findings highlight the utility of laboratory pain testing methods for understanding individual differences in inflammatory cytokines. Our findings suggest amplified pain-evoked proinflammatory cytokine reactivity among patients with SCD relative to carefully matched controls. Future research is warranted to evaluate the impact of enhanced pain-related cytokine response and whether it is predictive of clinical characteristics and the frequency/severity of pain crises in patients with SCD.

To study the visual acuity deficits and maturation in the fellow eyes of children with unilateral amblyopia who were treated with patching. Medical records of patients aged 4-13 years visiting a tertiary eye care center between January 2003 and December 2007 who were diagnosed for the first time with unilateral amblyopia were reviewed. Subjects included in the study were followed through April 2009. The baseline visual acuity in the fellow eye of amblyopic subjects was compared with that of age-matched healthy subjects. Changes in visual acuity in the amblyopic and fellow eyes during subsequent visits were analyzed. A total of 112 children with amblyopia were included (strabismic, 14; anisometropic, 51; combined mechanism, 47). Baseline visual acuity in the fellow eye of these children differed significantly from that of age-matched controls up to 8 years of age. Average logMAR acuity reached 0.0 at age 5 years in controls versus age 9 years in patients. Although the mean visual acuity of the fellow eyes improved during treatment, 21% developed temporary occlusion amblyopia. Full-time patching had no additional benefit when compared with part-time patching. Visual acuity in the fellow eye of children with unilateral amblyopia is reduced at baseline and matures more slowly than in healthy control patients. The risk for temporary occlusion amblyopia in the fellow eye is similar what has been previously reported. Copyright © 2012 American Association for Pediatric Ophthalmology and Strabismus.

Cerebrovascular reactivity (CVR) reflects the vasodilatory reserve of cerebral resistance vessels. Normal development in children is associated with significant changes in blood pressure, cerebral blood flow (CBF) and cerebral oxygen metabolism. Therefore, it stands to reason that CVR will also undergo changes during this period. The study acquired magnetic resonance imaging measures of CVR and CBF in healthy children and young adults to trace their changes with age. We found that CVR changes in two phases, increasing with age until the mid-teens, followed by a decrease. Baseline CBF declined steadily with age. We conclude that CVR varies with age during childhood, which prompts future CVR studies involving children to take into account the effect of development. Cerebrovascular reactivity (CVR) reflects the vasculature's ability to accommodate changes in blood flow demand thereby serving as a critical imaging tool for mapping vascular reserve. Normal development is associated with extensive physiological changes in blood pressure, cerebral blood flow and cerebral metabolic rate of oxygen, all of which can affect CVR. Moreover, the evolution of these physiological parameters is most prominent during childhood. Therefore, the aim of this study was to use non-invasive magnetic resonance imaging (MRI) to characterize the developmental trajectories of CVR in healthy children and young adults, and relate them to changes in cerebral blood flow (CBF). Thirty-four healthy subjects (17 males, 17 females; age 9-30 years) underwent CVR assessment using blood oxygen level-dependent MRI in combination with a computer controlled CO2 stimulus. In addition, baseline CBF was measured with a pulsed arterial spin labelling sequence. CVR exhibited a gradual increase with age in both grey and white matter up to 14.7 years. After this break point, a negative correlation with age was detected. Baseline CBF maintained a consistent negative linear correlation across the entire age range

To investigate the relationship between lens power and age as well as the relationship between lens power and axial length (AL) in Chinese children and adolescents. The participants underwent a comprehensive ophthalmic examination that included AL, cycloplegic refraction, and Pentacam measurements. The crystalline lens power was calculated using Bennett's formula and then compared among the children of different age groups, refractive statuses, and AL categories. The association of lens power and AL was analyzed using multiple regression. A total of 1992 children and adolescents aged 6- to 18-years old were included. The difference in lens power was greater before 10-years old, followed by a relatively smaller difference in children aged 10 to 14 years and the difference in lens power came to a near plateau in adolescents after 14-years old. The negative association between lens power and AL was found to be more evident in nonmyopes than in myopes irrespective of age (younger than 10 years: nonmyopes: β = -1.499, myopes: β = -0.872; older than 10 years: nonmyopes: β = -1.288, myopes: β = -0.390, all P < 0.001). The lens power in children and adolescents aged 6 to 18 years exhibited three stages. The association between lens power and AL differed between the nonmyopes and myopes. These findings suggested that less reduction in lens power might be associated with both growing age and increasing AL in myopes.

We have completed a genome-wide linkage scan for healthy aging using data collected from a family study, followed by fine-mapping by association in a separate population, the first such attempt reported. The family cohort consisted of parents of age 90 or above and their children ranging in age from 50 to 80. As a quantitative measure of healthy aging, we used a frailty index, called FI34, based on 34 health and function variables. The linkage scan found a single significant linkage peak on chromosome 12. Using an independent cohort of unrelated nonagenarians, we carried out a fine-scale association mapping of the region suggestive of linkage and identified three sites associated with healthy aging. These healthy-aging sites (HASs) are located in intergenic regions at 12q13-14. HAS-1 has been previously associated with multiple diseases, and an enhancer was recently mapped and experimentally validated within the site. HAS-2 is a previously uncharacterized site possessing genomic features suggestive of enhancer activity. HAS-3 contains features associated with Polycomb repression. The HASs also contain variants associated with exceptional longevity, based on a separate analysis. Our results provide insight into functional genomic networks involving non-coding regulatory elements that are involved in healthy aging and longevity.

Healthy Start is a 3-year demonstration and education research project designed to evaluate the effectiveness of a multidimensional cardiovascular (CV) risk reduction intervention in preschool centers over a 3-year period of time. Two primary interventions are employed. The first is the preschool food service intervention program designed to reduce the total fat in preschool meals and snacks to less than 30% of calories and reduce the saturated fat to less than 10% of calories. The second major intervention is a comprehensive preschool health education curriculum, focused heavily on nutrition. Effectiveness of the intervention will be determined through evaluation of changes in dietary intake of preschool children at school meals and snacks, especially with respect to intake of total and saturated fat. Evaluation of the education component will include assessment of program implementation by teachers, assessment of changes in nutrition knowledge by preschool children, and assessment of changes in home meals that children consume (total and saturated fat content). Blood cholesterol will be evaluated semiannually to evaluate changes that may be due to modification of dietary intake. Growth and body fatness will also be assessed. While substantial efforts have targeted CV risk reduction and health education for elementary school children, similar efforts aimed at preschool children have been lacking. The rationale for beginning CV risk reduction programs for preschool children is based upon the premise that risk factors for heart disease are prevalent by 3 years of age and tend to track over time, most commonly hypercholesterolemia and obesity, both related to nutrition. Since the behavioral antecedents for nutritional risk factors begin to be established very early in life, it is important to develop and evaluate new educational initiatives such as Healthy Start, aimed at the primary prevention of cardiovascular risk factors in preschool children.

To determine the relationship between healthy lifestyle behaviours of mothers and obesity in their pre-school children. The cross-sectional study was performed in a district of Istanbul, Turkey, between April and June 2011, and comprised children aged 4-6 years attending public pre-schools and their mothers.. Data was obtained using a questionnaire and Healthy Lifestyle Behaviours Scale-II. Number Cruncher Statistical System 2007 was used for statistical analysis. Of the 531 children in the study, 246(46.3%) were girls. Overall prevalence of overweight was 136(25.6%), obesity 77(14.5%)Overweight mothers were 126(23.7%), and obese mothers were 31(5.8%). The mothers of obese children obtained lower scores in the physical activity (p<0.05) and nutrition (p=0.001) subscales, and their total score was also lower (p<0.05).. Lifestyle behaviours of mothers, especially with respect to nutrition and physical activity, may influence obesity among preschool children. Strategies should be developed to improve the physical activity and eating habits of mothers.

To assess the effectiveness of a child care center-based parent and teacher healthy lifestyle role-modeling program on child nutrition and physical activity outcomes. Child care centers (N = 28) serving low-income families were randomized to intervention or control arms. Intervention centers (N = 12) implemented (1) menu modifications, (2) a child's healthy lifestyle curriculum, and (3) an adult (teacher- and parent-focused) healthy lifestyle role-modeling curriculum. Control centers (N = 16) received an attention control safety curriculum. Nutrition and physical activity data were collected at the beginning (T1) and at the end (T2) of the school year. Exploratory factor analysis identified positive and negative nutrition and physical activity practices by children, parents, and teachers. Intervention parents' baseline (β = .52, p < .0001) and school year consumption (β = .47, p < .0001) of fruits/vegetables significantly increased their children's consumption of fruits/vegetables from T1 to T2. Intervention parents significantly influenced a decrease in children's junk food consumption (β = -.04, p < .05), whereas control parents significantly influenced an increase in their children's junk food consumption (β = .60, p < .001) from T1 to T2. Control children showed a significant increase in junk food consumption (β = .11, p = .01) and sedentary behavior (β = .09, p < .005) from T1 to T2. Teachers did not significantly influence preschool-age children's nutrition or physical activity patterns from T1 to T2. Parent nutrition and physical activity patterns significantly influence their preschool-age children's consumption of fruits/vegetables, junk food, and level of sedentary behavior. Future obesity prevention intervention efforts targeting this age group should include parents as healthy lifestyle role models for their children.

We evaluate the value of an internet-based educational animated video designed to prepare children for MRI scans, and whether this video reduces scan-related anxiety in children with a neurological disorder, and healthy controls. Participants completed a pre- and post-scan questionnaire evaluating participant online viewing behaviour, understanding of the MRI procedure, anxiety regarding the MRI, impact of animation in preparing the child and whether the child's expectation of the MRI scan matched their experience. 21 children were recruited (12 healthy controls) ranging in age from 6.5 to 11.5 years. The animation was successfully accessed by participants on a range of digital devices and had high levels of approval. Children who viewed the animation had a good understanding of the MRI procedure and low anxiety levels prior to the scan, and reported that their expectations broadly matched the real-life MRI experience. Children reported that the animation positively impacted on their preparation with similar ratings before and after the scan, and the impact on preparation was rated greater by younger children. There were no group differences between healthy children and those with the neurological disorder for ratings of anxiety, impact on preparation and expectation of the experience. This evaluation demonstrates accessibility, acceptability and relevance of internet-based educational animation for typically developing children, and children with a neurodisability aged 6 to 11 years, with positive impact on preparation for MRI. Advances in knowledge: The internet-based educational animation provides a widely accessible tool to support preparation of children for non-sedated MRI.

The aims of this study were to determine if quality of life (QOL) among Arab Muslim hematopoietic stem cell transplantation (HSCT) survivors differs from that of a healthy matched comparison group and to examine the relationships of demographic and medical variables and perceived social support with post-HSCT QOL. HSCT survivors (n = 63) were recruited from the King Hussein Cancer Center outpatient clinic. A matched (age, gender, education), healthy comparison group (n = 63) was recruited through public advertisements. Participants completed the EORTC-30 QOL scale and the Medical Outcomes Study Social Support Survey. Differences were found between the Arab Muslim HSCT survivor and healthy comparison groups for physical functioning (p < .0001), role functioning (p < .01), social functioning (p < .0001) QOL domains, and an overall symptom score (p = .003) with the HSCT group reporting poorer status than the healthy comparison group. Effect sizes for the three QOL domains ranged from .50 (role functioning) to 1.20 (social functioning). No significant difference was noted between the Arab Muslim HSCT and comparison groups in emotional and cognitive QOL domains. Higher overall symptom scores were significantly associated with poorer QOL across all QOL domains. Similar to prior research with HSCT survivors, results suggest that HSCT has a significant negative impact on QOL. However, despite this general similarity, results suggest that the needs and experience of Muslim Arab HSCT survivors might differ from those of Western HSCT survivors in the social and emotional QOL domains. Given growing numbers of Arab and Muslim cancer survivors in the USA and other Western countries, future research is warranted.

Understanding risk factors that may vary culturally can help improve preventive strategies for obesity. This is the first cross-sectional study aimed to determine the risk factors for overweight/obesity in children aged 2-6 years in a central Anatolian city in Turkey. A total of 1582 children (1351 healthy, 231 overweight/obese) aged 2-6 years were included from the Anthropometry of Turkish Children aged 0-6 years database. Age, gender, birth weight, birth order, mother's age, mother's body mass index (BMI), weight gain of mothers during pregnancy, presence of gestational diabetes, breastfeeding duration, history of formula feeding, mother's and father's education, mother's job, monthly income, smoking at home and physical activity, sleep duration and duration of television (TV) watching of the children were evaluated as independent risk factors. Logistic regression analyses were performed to investigate risk factors for overweight/obesity. Having a high family income compared to bad [odds ratio (OR)=1.96; 95% confidence interval (CI): 1.237-3.106], increased the time of watching TV during the weekend (OR=1.094; 95% CI: 1.032-1.159), and similar physical activity level according to their peers compared to less (OR=2.957; 95% CI: 1.056-8.282) were found to be significantly associated with a higher risk of overweight/obesity in children aged 2-6 years old. The early childhood period seems to be important in the establishment of healthy behavioral patterns, especially limitation of TV watching and encouragement of physical activity. Obesogenic environment in families with high incomes need to be revealed.

2008-01-01

Ecological validity of neuropsychological assessment includes the ability of tests to predict real-world functioning and/or covary with brain structures. Studies have examined the relationship between adaptive skills and test performance, with less focus on the association between regional brain volumes and neurobehavioral function in healthy children. The present study examined the relationship between temporal lobe gray matter volumes and performance on two neuropsychological tests hypothesized to measure temporal lobe functioning (Visual Perception-VP; Peabody Picture Vocabulary Test, Third Edition-PPVT-III) in 48 healthy children ages 5-18 years. After controlling for age and gender, left and right temporal and left occipital volumes were significant predictors of VP. Left and right frontal and temporal volumes were significant predictors of PPVT-III. Temporal volume emerged as the strongest lobar correlate with both tests. These results provide convergent and discriminant validity supporting VP as a measure of the “what” system; but suggest the PPVT-III as a complex measure of receptive vocabulary, potentially involving executive function demands.

2008-07-01

We set out to evaluate the friendships and social behaviour of school-aged children with migraine. Concern exists regarding the impact of paediatric migraine on daily activities and quality of life. We hypothesized that children with migraine would have fewer friends and be identified as more socially sensitive and isolated than comparison peers. Sixty-nine children with migraine participated in a school-based study of social functioning. A comparison sample without migraine included classmates matched for gender, race and age. Children with migraine had fewer friends at school; however, this effect was limited to those in elementary school. Behavioural difficulties were not found. Middle-school students with migraine were identified by peers as displaying higher levels of leadership and popularity than comparison peers. Concern may be warranted about the social functioning of pre-adolescent children with migraine; however, older children with migraine may function as well as or better than their peers.

This study explored whether a cartoon show with healthy eating messages positively affected children's food choices and food preferences. Experimental between-subjects design. Four elementary schools in Portugal were investigated. Children (aged 4-8 years; n = 142) were randomly assigned to 1 of 2 groups: a comparison group (n = 73) was exposed to cartoons with no reference to food and an intervention group (n = 69) was exposed to cartoons with healthy eating messages. After viewing, each child was given the opportunity to eat ad libitum for 10 minutes from a small selection of snack foods. Number of healthy and unhealthy food items chosen. Food preferences were measured using an adapted version of the Leeds Food Preference Checklist. Generalized linear models were used to test for differences between groups. Results were considered significant at P ≤ .05. Children in the experimental group chose significantly more healthy food items than did those in the comparison group (B = -.600; SE = .19; P < .05). Future studies may address the effect of prolonged exposure to healthy eating cartoons. Cartoons can be used to promote healthy food choices and can be a part of health promotion campaigns.

Background: Dietary habits are established in childhood and will persist until adulthood, being one of the human health pillars. Many diseases of humans have roots in the individuals’ diet, of which dental caries are one of the common infectious diseases. Diabetes Mellitus is also considered as the most common metabolic disorder in children. Objectives: The purpose of this study was to compare the dietary patterns of children with type I Diabetes Mellitus with that of non-diabetic children, in relation to dental caries. Materials/Patients and Methods: In this study, 31 patients (13 boys and 18 girls, mean age of 11 ± 5.4 years) with type I Diabetes Mellitus referred to the Diabetes Mellitus Center and university hospitals were selected. Controls were 31 healthy students matched for age and sex. The study was based on the data obtained from the questionnaire containing information about dietary patterns and oral hygiene habits, social class and decayed/missing/filled teeth (DMFT) index. Dietary patterns were assessed using a food frequency questionnaire developed on the basis of caries preventing or inducing foods and then scored. Data were analyzed by using the t-test and McNamara’s test. Results: Diabetic children had less frequent cariogenic snacks than their controls. The mean diet scores for diabetic and healthy subjects were 7.65 ± 3.27 and 11.9 ± 2.03 (P < 0.05), respectively. There was no significant difference in DMFT between the diabetics and controls (3.71 ± 2.48 vs. 4.35 ± 2.74, respectively). There were also no differences in frequency of tooth brushing and use of mouth washes. However, more diabetics reported that they have never used dental floss compared to controls (42.2% vs. 71%, P < 0.05). Having cheese with bread as snack was more prevalent in diabetics (P < 0.05).There was a positive correlation between DMFT and dietary scores (r = 0.3, P < 0.05). Conclusions: Controls scored higher in their dietary habits and dental flossing but lower

Objective Children with attention-deficit/hyperactivity disorder (ADHD) have delayed cortical maturation, evidenced by regionally specific slower cortical thinning. However, the relationship between cortical maturation and attention capacities in typically developing children is unknown. This study examines cortical thickness correlates of inattention symptoms in a large sample of healthy children. Method Data from 357 healthy subjects (6.0–18.4 years of age) were obtained from the NIH MRI Study of Normal Brain Development. In cross-sectional analysis (first visit, n = 257), Child Behavior Checklist Attention Problems (AP) scores were linearly regressed against cortical thickness, controlling for age, gender, total brain volume, and site. For longitudinal data (up to three visits, n = 357/672 scans), similar analyses were performed using mixed-effects linear regressions. Interactions of AP with age and gender were tested. Results A cross-sectional “AP by age” interaction was found in bilateral orbito-frontal cortex, right inferior frontal cortex, bilateral ventromedial prefrontal cortex, bilateral dorsolateral prefrontal cortex, and several additional attention network regions. The interaction was due to negative associations between AP and thickness in younger subjects (6–10 years of age) that gradually disappeared over time secondary to slower cortical thinning. Similar trends were present in longitudinal analyses. Conclusions Higher AP scores were associated with thinner cortex at baseline and slower cortical thinning with aging in multiple areas involved in attention processes. Similar patterns have been identified in ADHD, suggesting a dimensional component to the link between attention and cortical maturation. The identified association between cortical maturation and attention in healthy development will help to inform studies of neuroimaging biomarkers of ADHD. PMID:22176936

There is increasing evidence that community acquired S. aureus infections are spreading among healthy children. Nasal colonization with S. aureus plays pivotal role in the increasing prevalence of resistant community acquired S. aureus infections worldwide. A regular surveillance system is important in ensuring quality of patient care. The aim of the study was to assess the prevalence of and the factors associated with nasal carriage of S. aureus and its antibiotic sensitivity pattern among healthy children in Ujjain, India. A prospective study was done in paediatric outpatient clinics of R.D. Gardi medical college Ujjain, India. Healthy children from 1 month to 59 months of age were included. Information on previously known risk factors for nasal colonization was collected using a pre-tested questionnaire. Swabs from anterior nares were collected and transported in Amies transport media with charcoal and cultured on 5% sheep blood agar. Antibiotic sensitivity tests were performed using Kirby Bauer's disc diffusion method according to performance standards of Clinical and Laboratory Standard Institute guidelines. Of the 1,562 children from 1-month up-to five years of age included in the study 98 children tested positive for nasal carriage of S. aureus. The prevalence of nasal carriage of S. aureus was 6.3% (95% CI 5.1-7.5) out of which 16.3% (95% CI 8.9-23.8) were methicillin-resistant S. aureus (MRSA). The factors associated with nasal carriage were "child attending preschool" (OR 4.26, 95% CI 2.25-8.03; P = 0.007) or "school" (OR 3.02, 95% CI 1.27-7.18; P < 0.001) and "family size more than 10 members" (OR 2.76 95% CI 1.06-7.15; P = 0.03). The sensitivity pattern of isolated S. aureus showed resistance to commonly used oral antibiotics while resistance to glycopeptides was not noted. We found a relatively low rate of nasal carriage of S. aureus in children below five years when compared to children of older age groups in India. Yet, prevalence of MRSA was

Background: Group A streptococcus (GAS) is the commonest bacterial cause of pharyngitis. Children in the age group of 5–15 years are most commonly affected. It can also colonize throats of healthy children in this age group. Both cases and carriers can transmit it in the community. Methods: Throat swab samples were collected from 1849 asymptomatic and 371 symptomatic children. Results: The rate of isolation of GAS was 1.41% among the asymptomatic group and 7.55% among the symptomatic group. Nine different emm types were encountered in the asymptomatic children and 14 among the symptomatic children. Conclusion: Throat swab cultures must be used in all cases of pharyngitis. Early and appropriate antibiotic therapy will prevent complications. Asymptomatic throat carriage of GAS in children was low in our study. However, they can still act as reservoirs. Emm typing helps in understanding epidemiology and finding new types. PMID:26743337

There are limited data regarding the prevalence and risk factors relating to hypovitaminosis D in children of Thailand, a tropical country with abundant sunlight. The objective of this study was to assess the prevalence of hypovitaminosis D and examine factors associated with hypovitaminosis D in school-aged children in Bangkok, Thailand - a centrally located capital city. This cross-sectional study evaluated 159 healthy children (33.3% boys and 66.7% girls), aged 6 to 12 years, in Bangkok, Thailand (located at 13.45°N). Fasting plasma samples were examined for total 25-hydroxyvitamin D [25(OH)D] using electrochemiluminescence immunoassay. Demographic characteristics (age, sex, household income), past medical history (birth weight, allergic diseases, hospitalization), amount of sun exposure, anthropometric data, and selected biochemical tests were used to investigate for factors associated with hypovitaminosis D. Overall, the mean ± SD level of plasma 25(OH)D was 64.0 ± 15.1 nmol/L. Hypovitaminosis D (< 75 nmol/L) was presented in 79.2% of subjects. Of these, the prevalence of vitamin D insufficiency and vitamin D deficiency were 59.7% and 19.5%, respectively. In univariate analysis, children with hypovitaminosis D (< 75 nmol/L) had a higher mean body mass index (BMI) percentile than the vitamin D-sufficient group (56.7 ± 33.9 vs. 42.6 ± 36.0; P-value = 0.04). Plasma PTH levels in the children with hypovitaminosis D were significantly higher than in the children with normal levels of vitamin D (4.34 ± 1.38 vs 3.78 ± 1.25 pmol/L; P-value = 0.04). In multivariate analysis, high BMI percentile and high PTH concentration were the parameters associated with 25(OH)D level < 75 nmol/L. The prevalence of hypovitaminosis D in healthy Thai children is very high, despite their exposure to sunlight, and that prevalence increases in children with a high BMI percentile. As a result, a formal recommendation for vitamin D

Human constitutional types are genetically predetermined and remains constant in their basic features. The type could be changed to a certain extent by environmental factors, diseases and some other factors. To define the somatotype of children with type 1 diabetes mellitus and compare it to the somatotype of healthy children. An anthropometrical study was performed in 71 boys and 69 girls with type 1 diabetes. The anthropometric measures including weight, height, corrected contracted arm girth, medial calf girth, triceps brachii, subscapular and suprailiac skinfolds, biepicondylar humerus breadth and biepicondylar femur breadth were taken to determine the somatotype. The somatotypes were determined according to Heath-Carter method (1967). The sample was divided into two age groups for both sexes: from 7 to 12 and from 12 to 18 years. One hundred healthy age-matched boys and girls were used as a control sample in the study. The diabetic boys aged 7 - 12 years presented with balanced mesomorph somatotype (endo 2.7-meso 4.8-ecto 2.3), while the healthy boys were with endomorphic mesomorph somatotype (3.4-5.2-2.7). Both the diabetic and healthy boys aged 12-18 years presented with balanced mesomorph somatotype (3.1-4.2-3.5 and 3.4-5.0-3.2, respectively). The somatotype of the diabetic girls aged 7-12 years was balanced mesomorph (3.0-4.2-2.8). The healthy girls of the same age presented with the endomorphic mesomorph (3.7-4.9-2.7). The diabetic girls aged 12-18 years were with mesomorphic endomorph somatotype (4.9-3.7-2.5) and the somatotype of the healthy girls was mesomorph endomorph (4.5-4.1-2.9). Mesomorphy was dominant in the diabetic and healthy boys. Mesomorphy was dominant in the diabetic and healthy girls aged 7-12 years. In the 12-18 age group endomorphy increased becoming dominant in the diabetic children and equal to mesomorphy in the healthy ones.

To explore association between medically unexplained symptoms in children in Pakistan with emotional difficulties and functional impairments. We conducted a matched three-group case-control study of 186 children aged 8-16 years in Lahore, Pakistan. Cases were 62 children with chronic somatic symptoms for which no organic cause was identified after investigations. Two control groups of 62 children with chronic medical paediatric conditions, and 62 healthy children were identified. Cases and controls were matched for gender, age, and school class. Somatisation was measured with the Children's Somatisation Inventory (CSI-24) while anxiety and depression were measured with the Spencer Children's Anxiety Scale and the Short Mood and Feelings Questionnaire respectively. All questionnaires were translated into Urdu. Mean age was 11.7 years (SD=2.1). Cases scored significantly higher on somatisation (CSI-24), anxiety and depression than both control groups. Paediatric controls scored significantly higher than healthy controls on all three measures. Two hierarchical linear regression models were used to explore if somatisation predicted depression and anxiety while controlling for several confounders. Somatisation (higher CSI-24 scores) independently and significantly predicted higher anxiety (β=.37, p=.0001) and depression (β=.41, p=.0001) scores. This is the first study to show an association between medically unexplained symptoms and anxiety and depression in Pakistani children. This highlights the importance of screening for emotional difficulties in children presenting with unexplained somatic symptoms in this region. Copyright © 2013 Elsevier Inc. All rights reserved.

Fronto-amygdalar networks are implicated in childhood psychiatric disorders characterized by high rates of externalizing (aggressive, noncompliant, oppositional) behavior. Although externalizing behaviors are distributed continuously across clinical and nonclinical samples, little is known about how brain variations may confer risk for problematic behavior. Here, we studied cortical thickness, amygdala volume, and cortico-amygdalar network correlates of externalizing behavior in a large sample of healthy children. Two hundred ninety-seven healthy children (6-18 years; mean = 12 ± 3 years), with 517 magnetic resonance imaging scans, from the National Institutes of Health Magnetic Resonance Imaging Study of Normal Brain Development, were studied. Relationships between externalizing behaviors (measured with the Child Behavior Checklist) and cortical thickness, amygdala volume, and cortico-amygdalar structural networks were examined using first-order linear mixed-effects models, after controlling for age, sex, scanner, and total brain volume. Results significant at p ≤ .05, following multiple comparison correction, are reported. Left orbitofrontal, right retrosplenial cingulate, and medial temporal cortex thickness were negatively correlated with externalizing behaviors. Although amygdala volume alone was not correlated with externalizing behaviors, an orbitofrontal cortex-amygdala network predicted rates of externalizing behavior. Children with lower levels of externalizing behaviors exhibited positive correlations between orbitofrontal cortex and amygdala structure, while these regions were not correlated in children with higher levels of externalizing behavior. Our findings identify key cortical nodes in frontal, cingulate, and temporal cortex associated with externalizing behaviors in children; and indicate that orbitofrontal-amygdala network properties may influence externalizing behaviors, along a continuum and across healthy and clinical samples.

There are aging- and stroke-induced changes on sensorimotor control in daily activities, but their mechanisms have not been well investigated. This study explored speed-, aging-, and stroke-induced changes on sensorimotor control. Eleven stroke patients (affected sides and unaffected sides) and 20 control subjects (10 young and 10 age-matched individuals) were enrolled to perform elbow tracking tasks using sinusoidal trajectories, which included 6 target speeds (15.7, 31.4, 47.1, 62.8, 78.5, and 94.2 deg/s). The actual elbow angle was recorded and displayed on a screen as visual feedback, and three indicators, the root mean square error (RMSE), normalized integrated jerk (NIJ) and integral of the power spectrum density of normalized speed (IPNS), were used to investigate the strategy of sensorimotor control. Both NIJ and IPNS had significant differences among the four groups (P<0.01), and the values were ranked in the following order: young controls < age-matched controls aging-induced increase in reliance on feedback control. The RMSE increased with the increase in the target speed and the NIJ and IPNS initially declined and then remained steady for all four groups, which indicated a shift from feedback to feedforward control as the target speed increased. The feedback-feedforward trade-off induced by stroke, aging and speed might be explained by a change in the transmission delay and neuromotor noise. The findings in this study improve our understanding of the mechanism underlying the sensorimotor control and neurological changes caused by stroke and aging. PMID:26030289

Genetics of healthy aging and longevity.

PubMed

Brooks-Wilson, Angela R

2013-12-01

Longevity and healthy aging are among the most complex phenotypes studied to date. The heritability of age at death in adulthood is approximately 25 %. Studies of exceptionally long-lived individuals show that heritability is greatest at the oldest ages. Linkage studies of exceptionally long-lived families now support a longevity locus on chromosome 3; other putative longevity loci differ between studies. Candidate gene studies have identified variants at APOE and FOXO3A associated with longevity; other genes show inconsistent results. Genome-wide association scans (GWAS) of centenarians vs. younger controls reveal only APOE as achieving genome-wide significance (GWS); however, analyses of combinations of SNPs or genes represented among associations that do not reach GWS have identified pathways and signatures that converge upon genes and biological processes related to aging. The impact of these SNPs, which may exert joint effects, may be obscured by gene-environment interactions or inter-ethnic differences. GWAS and whole genome sequencing data both show that the risk alleles defined by GWAS of common complex diseases are, perhaps surprisingly, found in long-lived individuals, who may tolerate them by means of protective genetic factors. Such protective factors may 'buffer' the effects of specific risk alleles. Rare alleles are also likely to contribute to healthy aging and longevity. Epigenetics is quickly emerging as a critical aspect of aging and longevity. Centenarians delay age-related methylation changes, and they can pass this methylation preservation ability on to their offspring. Non-genetic factors, particularly lifestyle, clearly affect the development of age-related diseases and affect health and lifespan in the general population. To fully understand the desirable phenotypes of healthy aging and longevity, it will be necessary to examine whole genome data from large numbers of healthy long-lived individuals to look simultaneously at both common and

Objective To examine autonomy-promoting parenting and independent problem-solving in children with food allergy. Methods 66 children with food allergy, aged 3–6 years, and 67 age-matched healthy peers and their mothers were videotaped while completing easy and difficult puzzles. Coders recorded time to puzzle completion, children’s direct and indirect requests for help, and maternal help-giving behaviors. Results Compared with healthy peers, younger (3- to 4-year-old) children with food allergy made more indirect requests for help during the easy puzzle, and their mothers were more likely to provide unnecessary help (i.e., explain where to place a puzzle piece). Differences were not found for older children. Conclusions The results suggest that highly involved parenting practices that are medically necessary to manage food allergy may spill over into settings where high levels of involvement are not needed, and that young children with food allergy may be at increased risk for difficulties in autonomy development.

Background: Numerous studies show higher cough reflex sensitivity (CRS) and cough outcomes in children compared to adults and in females compared to males. Despite close link that exists between cough and environment the potential influence of environmental air pollution on age- and gender -related differences in cough has not been studied yet. Purpose: The purpose of our study was to analyse whether the effects of exposure to environmental tobacco smoke (ETS) from parental smoking and PM10 from living in urban area are implied in age- and gender-related differences in cough outcomes of healthy, non-asthmatic children. Assessment of CRS using capsaicin and incidence of dry and wet cough was performed in 290 children (mean age 13.3 ± 2.6 years (138 females/152 males). Results: CRS was significantly higher in girls exposed to ETS [22.3 μmol/l (9.8–50.2 μmol/l)] compared to not exposed girls [79.9 μmol/l (56.4–112.2 μmol/l), p = 0.02] as well as compared to exposed boys [121.4 μmol/l (58.2–253.1 μmol/l), p = 0.01]. Incidence of dry cough lasting more than 3 weeks was significantly higher in exposed compared to not exposed girls. CRS was significantly higher in school-aged girls living in urban area [22.0 μmol/l (10.6–45.6 μmol/l)] compared to school-aged girls living in rural area [215.9 μmol/l (87.3–533.4 μmol/l); p = 0.003], as well as compared to teenage girls living in urban area [108.8 μmol/l (68.7–172.9 μmol/l); p = 0.007]. No CRS differences were found between urban and rural boys when controlled for age group. No CRS differences were found between school-aged and teenage boys when controlled for living area. Conclusions: Our results have shown that the effect of ETS on CRS was gender specific, linked to female gender and the effect of PM10 on CRS was both gender and age specific, related to female gender and school-age. We suggest that age and gender related differences in incidence of cough and CRS might be, at least partially

To investigate the prevalence of nutritional parameters of risk for cardiovascular disease (CVD) and kidney diseases in healthy preschool children. This is an observational cross-sectional study with 60 healthy children, of both genders, aged two to six years old and 56 mothers, in Belo Horizonte, Minas Gerais, Brazil. Preschool children and their families with regular activities at public schools were invited to paticipate in the study. The following characteristics were assessed: Socio-demographic condictions, clinical health, anthropometric, biochemical, lifestyle and data on food consumption. The 56 healthy children were divided into two groups, overweight (C1) and non-overweight (C2), as well as their mothers, respectively, in overweight (M1) and non-overweight (M2). Nutritional status was defined according to results obtained through the Anthro ® Software for nutritional analysis. Thirty-five children were male, with mean age of 4.44 ± 1.0 years old. Eighty-nine percent of them were eutrophic, 86.7% were sedentary and they had five meals a day. Body mass index (BMI) for age and total cholesterol (TC) was higher on C1 ( P = 0.0001) and high density lipoprotein cholesterol (HDL-c) was higher on C2. Mothers were 32.5 ± 7.1 years old, mostly married and employed. Eighty-six percent of them were sedentary and 62.5% were overweight with BMI = 26.38 ± 5.07 kg/m 2 . Eighteen percent of the overweight mothers had isolated total hypercholesterolemia (TC levels elevated) and 12.5% had low HDL-c levels. The present study showed an association between overweight and obesity during the preschool years and the correspondent mothers' nutritional status of overweight and obesity (OR = 4.96; 95%CI: 0.558-44.17). There was a positive correlation between the food risk associated with CVD by children and mothers when their consumption was 4 times/wk ( P = 0.049; r = 0.516) or daily ( P = 0.000008; r = 0.892).

The aim of the present study was to evaluate any possible negative effect of diabetes on the self-esteem of children and adolescents with diabetes. Self-esteem was evaluated using the Culture-Free Self-Esteem Inventory (CFSEI-2) in 144 patients with Type 1 diabetes mellitus (T1DM; 7-18 years of age) treated in a diabetes center and compared against that of 136 healthy children and adolescents. Self-esteem was correlated with age (P = 0.017), but not with diabetes (P = 0.886). The median CFSEI-2 score for both healthy and diabetic children was 22. There was no significant correlation between self-esteem and sex, body mass index (BMI), physical exercise, HbA1c or parental educational level. According to Spearman's rank correlation coefficient (r(s)), there was a significant association between age and self-esteem (r(s) = -0.15). Conversely, although BMI (r(s) = -0.09) and treatment duration (r(s) = -0.107) had a slight negative effect on self-esteem and the duration of physical exercise (r(s) = 0.11) and parental education (r(s) = 0.07) seemed to have a positive effect, the associations did not reach statistical significance. Self-esteem in diabetic children is mainly affected by their age, level of physical activity and level of family support. These findings emphasize the need to discriminate between glycemic control and diabetic adjustment. © 2010 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Blackwell Publishing Asia Pty Ltd.

Co-Sleeping among School-Aged Anxious and Non-Anxious Children: Associations with Sleep Variability and Timing.

Little is known about the co-sleeping behaviors of school-aged children, particularly among anxious youth who commonly present for the treatment of sleep problems. The current study examined the occurrence of co-sleeping in both healthy and clinically anxious children and its associated sleep patterns. A total of 113 children (ages 6-12), 75 with primary generalized anxiety disorder and 38 healthy controls, participated along with their primary caregiver. Families completed structured diagnostic assessments, and parents reported on their child's co-sleeping behaviors and anxiety severity. Children provided reports of anxiety severity and completed one week of wrist-based actigraphy to assess objective sleep patterns. A significantly greater proportion of anxious youth compared to healthy children co-slept, and greater anxiety severity was related to more frequent co-sleeping. Co-sleeping in anxious youth was associated with a delay in sleep timing and with greater sleep variability (i.e., more variable nightly sleep duration). All analyses controlled for child age, race/ethnicity, family income, and parental marital status. Co-sleeping is highly common in anxious school-aged children, with more than 1 in 3 found to co-sleep at least sometimes (2-4 times a week). Co-sleeping was even more common for youth with greater anxiety severity. Increased dependence on others to initiate and maintain sleep may contribute to poorer sleep in this population via shifted schedules and more variable sleep patterns.

Many changes happen during growth and development in an organism as a result of important hormon changes, especially biohumoral ones. These changes make a problem when interpreting biochemical results in pediatric population. The most important changes are intensive calcium and phosphorus metabolic turnover in bone tissue with changes in alkaline phosphatase activity as a result of osteoblast activity. The aim of this study was to follow the serum calcium and phosphorus concentration and alkaline phosphatase activity in children 1-15 years old in different growth and development period and of different sexes and to fortify the influence of growth and development dynamics on biohumoral status in healthy male and female children. We evaluated 117 healthy children of both sexes from 1-15 years of age and divided them into three age groups: 1-5, 6-10 and 11-15 years. We followed the serum calcium and phosphorus concentration and alkaline phosphatase activity in different groups and in different sexes. Our investigation found significantly higher values of serum calcium in boys than in girls with no important changes between the age groups and significantly higher values of serum phosphorus in the youngest age group in all children and in different sexes with no important sex differences. Alkaline phosphatase activity followed the growth spurt and was the biggest in 6-10 years group in girls and in 11-15 years group in boys.

The prevalence of IgG subclass deficiency in asthma is still controversial. Earlier studies often included patients receiving treatment with systemic steroids which can induce hypogammaglobulinaemia. Concentrations of IgG subclasses were studies in 200 children (aged 2-17 years) with asthma (mean asthma severity score (ASS) 2, range 1-4) who had not received systemic steroids for at least six weeks before investigation, and in 226 healthy age matched controls. The mean concentrations of IgG subclasses in children with asthma were within the 1SD range of those of the control group. In the group with asthma there was a trend towards higher levels of IgG1 and IgG4, whereas the number of children with low concentrations of IgG2 (< 2 SD of control serum samples; absolute concentrations 0.08-1.25 g/l) was slightly greater than in the group who did not have asthma (4.5 v 2.2%). Patients with subnormal concentrations of IgG2 could not be distinguished clinically or on the basis of case history and additional immunological studies did not show further abnormalities. Patients with severe asthma (ASS 3-4) had significantly higher concentrations of IgG4 (mean (SE) 0.53 (0.09) v 0.26 (0.04) g/l) than patients with mild asthma (ASS 1). No significant difference in subclass concentration was found between patients with atopic and those with non-atopic asthma. It is concluded that in an unselected group of children with asthma the mean IgG subclass concentrations do not differ significantly from a group of healthy age matched controls.

The Healthy Fitness Zone Continuum Score as a Measure of Change in Body Mass Index of School-Aged Children and Adolescents, Georgia, 2012-2014.

Saint-Maurice, Pedro F; Welk, Gregory J; Bai, Yang

The FitnessGram Healthy Fitness Zone continuum (HFZc) score reflects the relative difference of a person's body mass index (BMI) from the established FitnessGram standard. As such, it may provide added utility for public health programming and research on obesity among school-aged children and adolescents. We used the standard BMI Z (BMIz) score and the alternative HFZc score to describe changes in BMI of school-aged children and adolescents in Georgia over time. We compiled 2012-2014 BMI data from the Georgia FitnessGram database. The sample included 162 992 boys and 141 711 girls enrolled in 239 schools from a large urban district in Georgia. We analyzed trends in BMIz and HFZc scores separately for normal-weight, overweight, and obese categories for school-aged children and adolescents using hierarchical linear models. From 2012 to 2014, the BMIz score shifted favorably in up to 40.7% (2052/5047) of normal-weight, 51.0% (758/1485) of overweight, and 52.8% (5430/10 279) of obese students. We also found favorable shifts in HFZc score in up to 69.8% (105 831/151 739) of normal-weight, 78.3% (3605/4603) of overweight, and 80.8% (8305/10 279) of obese students. Compared with the BMIz score, the HFZc score may be a better indicator of favorable changes in BMI over time among school-aged children and adolescents with different baseline BMI levels, making it potentially valuable for use in individualized assessments, school programs, obesity research, and public health curriculum and policy development.

Healthy aging includes physical, psychological, social, and spiritual well-being in later years. The purpose of this study is to identify the psychosocial factors influencing healthy aging and examining their socio-demographic characteristics. Perceived health status, depression, self-esteem, self-achievement, ego-integrity, participation in leisure activities, and loneliness were identified as influential factors in healthy aging. 171 Korean adults aged between 45 and 77 years-old participated in the study. Self-reporting questionnaires were used, followed by descriptive statistics and multiple regressions as inferential statistical analyses. There were significant differences between participants' general characteristics: age, education, religion, housing, hobby, and economic status. The factors related to healthy aging had positive correlation with perceived health status, self-esteem, self-achievements, and leisure activities, and negative correlation with depression and loneliness. The factors influencing healthy aging were depression, leisure activities, perceived health status, ego integrity, and self-achievements. These factors were able to explain 51.9%. According to the results, depression is the factor with the greatest influence on healthy aging. Perceived health status, ego integrity, self-achievement, self-esteem, participation of leisure activities were also influential on healthy aging as beneficial factors.

Although the concept of healthy ageing has stimulated considerable interest, no generally accepted definition has been developed nor has its biological basis been determined. To develop a definition of healthy ageing and investigate its association with longevity and neuropathology. Analyses were based on cognitive, physical, and post-mortem assessments from 1991 to 1998 in the Nun Study, a longitudinal study of ageing in participants 75+ years at baseline. We defined three mutually exclusive levels of healthy ageing (excellent, very good, and good) based on measures of global cognitive function, short-term memory, basic and instrumental activities of daily living, and self-rated function. Mortality analyses were based on 636 participants; neuropathologic analyses were restricted to 221 who had died and were autopsied. Only 11% of those meeting criteria for the excellent level of healthy ageing at baseline subsequently died, compared with 24% for the very good, 39% for the good, and 60% for the remaining participants. Survival curves showed significantly greater longevity with higher levels of healthy ageing. The risk of not attaining healthy ageing, adjusted for age, increased two-fold in participants with brain infarcts alone, six-fold in those with Alzheimer neuropathology alone, and more than thirteen-fold in those with both brain infarcts and Alzheimer neuropathology. The biological validity of our definition of healthy ageing is supported by its strong association with mortality and longevity. Avoiding Alzheimer and stroke neuropathology is critical to the maintenance of healthy ageing, and the presence of both pathologies dramatically decreases the likelihood of healthy ageing.

Social participation becomes particularly important in middle childhood, as it contributes towards the acquisition and development of critical life skills such as developing friendships and a sense of belonging. However, only limited literature is available on the impact of communication difficulties on social participation in middle childhood. This study compared the participation patterns of school-age children with and without physical disabilities and complex communication needs in extracurricular activities. Participants included five children between 6-9 years of age with moderate-severe physical disability and complex communication needs, and five matched peers. Findings showed that children with physical disability and complex communication needs engaged in activities with reduced variety, lower frequency, fewer partners and in limited venues, but reported higher levels of enjoyment and preference for activity participation, than their matched peers. These children also had fewer same-aged friends, but more paid workers in their social circle. This small-scale descriptive study provides some preliminary evidence about the impact of severe communication difficulties on participation and socialization.

Subclinical obsessive-compulsive (OC) symptoms are frequently observed in children and have been reported to predict a subsequent diagnosis of OC disorder (OCD). Therefore, identifying the putative neurobiological signatures of such risk is crucial, because it would allow for the characterization of the underpinnings of OCD without the interfering effects of chronicity, medication, or comorbidities, especially when interpreted within the context of OCD clinical heterogeneity and taking into account normal neurodevelopmental changes. The present study aimed to identify the brain volumetric features associated with subclinical OC symptoms and the potential modulatory effects of sex and age in a large sample of healthy children. Two hundred fifty-five healthy children were assessed using the Obsessive-Compulsive Inventory-Child Version and underwent a brain structural magnetic resonance examination. The relation between total and symptom-specific scores and regional gray and white matter (GM and WM) volumes was evaluated. Participants were grouped according to sex and age (younger versus older) to assess the effect of these factors on symptom-brain morphometry associations. Ordering symptoms were negatively related to GM volumes in the ventral caudate. Hoarding symptoms were positively associated with GM and WM volumes in the left inferior frontal gyrus, and obsessing symptoms correlated negatively with GM and WM volumes in the right temporal pole. Doubt-checking symptoms correlated positively with WM volumes in the right inferior fronto-occipital fasciculus and the corpus callosum. Sex and age modulated some of these associations. Subclinical OC symptoms are associated with specific brain volumetric features, which could be considered potential neural signatures of increased risk for OCD.

Both selective attention and response inhibition can be assessed through the Stroop task and the Go/NoGo task (Go/NoGo). The color-word matching Stroop task (cwmStroop) differs from the traditional Stroop task in ways that make it easy to administer, and it enables the examiners to analyze reaction time. It is expected that the cwmStroop and Go/NoGo tasks will be useful as clinical assessments for children with developmental disorders and in combination with functional magnetic resonance imaging studies. The objectives of this study were to elucidate the pattern of developmental change in cwmStroop scores and Go/NoGo scores and to determine whether and how cwmStroop scores are related to Go/NoGo scores. The subjects consisted of 108 healthy Japanese children aged 6-14 years. We found that cwmStroop and Go/NoGo scores displayed clear developmental changes between 6 and 14 years of age. The children's scores on the 2 tasks followed different developmental courses, however, and the correlation between scores on the two tasks was weak on the whole. These results indicate that the cwmStroop and Go/NoGo tasks tap different aspects of selective attention and response inhibition. Therefore it is expected that the combination of both tests will be useful in the multifaceted assessment of selective attention and response inhibition in childhood.

Group A streptococcus (GAS) is the commonest bacterial cause of pharyngitis. Children in the age group of 5-15 years are most commonly affected. It can also colonize throats of healthy children in this age group. Both cases and carriers can transmit it in the community. Throat swab samples were collected from 1849 asymptomatic and 371 symptomatic children. The rate of isolation of GAS was 1.41% among the asymptomatic group and 7.55% among the symptomatic group. Nine different emm types were encountered in the asymptomatic children and 14 among the symptomatic children. Throat swab cultures must be used in all cases of pharyngitis. Early and appropriate antibiotic therapy will prevent complications. Asymptomatic throat carriage of GAS in children was low in our study. However, they can still act as reservoirs. Emm typing helps in understanding epidemiology and finding new types. © The Author [2016]. Published by Oxford University Press. All rights reserved.

2016-03-01

Prader-Willi syndrome (PWS) is a rare genetic disorder associated with distinct abnormal behaviors including hyperphagia, profound social deficits, and obsessive-compulsive tendencies. PWS males showed reduced oxytocin receptor (OTR) gene expression and density in the hypothalamic paraventricular nucleus that may play a role in PWS psychopathology. Oxytocin is an anorexigenic neuropeptide similar to vasopressin that is associated with social cognition and obsessive-compulsive behavior. To evaluate oxytocin biology in PWS, we examined overnight fasting plasma oxytocin levels in 23 children with PWS (mean ± SD age: 8.2 ± 2.0 year) having genetic confirmation and 18 age matched healthy unrelated siblings without PWS (mean ± SD age: 8.2 ± 2.3 year) and a similar gender ratio under the same clinical assessments, specimen processing and laboratory conditions. Multiplex immune assays were carried out using the Milliplex Human Neuropeptide Magnetic panel and the Luminex system. Natural log-transformed oxytocin levels were analyzed using general linear model adjusting for diagnosis, gender, age and body mass index (BMI). Oxytocin plasma levels were significantly elevated in children with PWS (168 ± 121 pg/ml) compared with unrelated and unaffected siblings without the diagnosis of PWS (64.8 ± 83.8 pg/ml, F = 8.8, P < 0.01) and the diagnosis of PWS predicted oxytocin level (F = 9.5, P < 0.003) in controlled regression analysis with an overall model fit R(2) = 0.33 (P < 0.01). The symptoms of hyperphagia, anxiety and repetitive behaviors classically seen in PWS may be related to the disruption of oxytocin responsivity or feedback in the hypothalamic paraventricular nucleus possibly influencing vasopressin signaling. Further study is needed to characterize oxytocin function in PWS. © 2015 Wiley Periodicals, Inc.

Maximal mouth opening (MMO) is used as a marker of masticatory pathology. However, MMO among children varies considerably with their age, height, sex, and race. While accurate percentile of normal mouth opening and relationship with anthropometric measurement are not precisely defined for the Indian population, we designed prospective, observational study to define the percentiles for normal MMO in our children. A total of 985 children, 560 males and 425 females, in the age range of 5-18 years attending the pediatric clinic in a tertiary care center in Western India were studied. In addition to the basic demographic data, MMO was measured in these children. The children were asked to open their mouth maximally until no further opening was possible. The distance from the incisal edge of the upper incisor teeth to the incisal edge of the lower incisor teeth was measured using a calibrated fiber ruler. Statistical analysis was performed to assess the impact of other anthropometric measures such as age, gender, and height on MMO. The mean MMO for males was 44.24 (±5.84) mm and for females was 43.5 (±5.19) mm. Age- and height-related percentiles were created for girls and boys separately, showing the 5 th , 10 th , 25 th , 50 th , 75 th , 90 th , and 95 th percentiles from 5 through 18 years of age with 86-185 cm height. The MMO percentile range for different age and height groups is established for the normal children. The mouth opening seems to increase with the age and especially with the height as per the skeletal growth. Height affects mouth opening more than the age.

Forensic document examiners (FDE) called upon to distinguish a genuine from a forged signature of an elderly person are often required to consider the question of age-related deterioration and whether the available exemplars reliably capture the natural effects of aging of the original writer. An understanding of the statistical relationship between advanced age and handwriting movements can reduce the uncertainty that may exist in an examiner’s approach to questioned signatures formed by elderly writers. The primary purpose of this study was to systematically examine age-related changes in signature kinematics in healthy writers. Forty-two healthy subjects between the ages of 60–91 years participated in this study. Signatures were recorded using a digitizing tablet and commercial software was used to examine the temporal and spatial stroke kinematics and pen pressure. Results indicated that vertical stroke duration and dysfluency increased with age, whereas vertical stroke amplitude and velocity decreased with age. Pen pressure decreased with age. We found that a linear model characterized the best-fit relationship between advanced age and handwriting movement parameters for signature formation. Male writers exhibited stronger age effects than female writers, especially for pen pressure and stroke dysfluency. The present study contributes to an understanding of how advanced age alters signature formation in otherwise healthy adults. PMID:24673648

The objective of the present study was to determine the factors associated with low concentrations of 25-hydroxy vitamin D (vitamin D deficiency) in healthy children in Qatar. The survey was a cross-sectional study conducted at the Primary Health Care Clinics over the period from August 2007 to March 2008. Subjects The study was carried out among healthy Qatari nationals, male and female, aged below 16 years. A random sample of 650 healthy subjects who visited the Primary Health Care Centers for any reason other than acute or chronic disease were approached and 458 subjects gave consent; a response rate of 70.5%. Face-to-face interviews were based on a questionnaire that included variables such as socio-demographic information, assessment of non-dietary covariates, assessment of dietary intake, vitamin D intake, type of feeding, clinical manifestations and laboratory investigations. The subjects' health status was assessed by medical conditions, family history, body mass index, past or present clinical manifestations, 25-hydroxy vitamin D, calcium, alkaline phosphates, phosphorus, HbA1C, Parathyroid Hormone (PTH), magnesium and creatinine analysis. The study revealed that vitamin D deficiency was highly prevalent in Qatari adolescents (11-16 years old; 61.6%), followed by the 5-10 year olds (28.9%) and those below 5 years old (9.5%). Vitamin D deficiency increased with age and there was a significant difference between vitamin D-deficient and normal children in their age groups (P =0.013). The body mass index was significantly lower in vitamin D-deficient children (19.6+/-3.6; P =0.019). A family history of vitamin D deficiency was more frequent in children with vitamin D deficiency (33.7%) than in normal children (24.5%). Most of the vitamin D-deficient children had no physical activity (60.6%) and no exposure to sunlight (57.5%). There was a significant difference between both groups in terms of family history of vitamin D deficiency, physical activity, exposure

To study the relationship of gamma glutamyl transferase (GGT) with insulin resistance markers [fasting insulin and Homeostasis Model Assessment of-insulin resistance (HOMA-IR)] and to assess the role of GGT as a determinant of insulin resistance in healthy obese children. Fifty healthy obese children (boys and girls with mean age 9.2 +/- 0.73 and 8.8 +/- 0.74 years) born to diabetic mothers were studied. In all the subjects, anthropometric measurements viz, BMI and body weight were studied. The biochemical parameters analysed in fasting samples of subjects were plasma glucose, plasma insulin, serum GGT and calculation of HOMA-IR. The fifty studied subjects belonged to age group 8 to12 years. The difference in mean age of boys and girls was not significant (p = 0.09). Body weight values in all subjects ranged from 20 to 78 kgs and BMI values ranged from 14.5 to 42.1 Kg/m2. No significant difference was observed between body weight and BMI values when compared between boys and girls. A similar trend was observed in the values of biochemical parameters viz, fasting glucose, fasting insulin and HOMA-IR levels when compared between boys and girls (p = 0.72, p = 0.80, p = 0.59). Serum GGT correlated significantly with age, body weight, BMI, fasting insulin and HOMA-IR levels. HOMA-IR values also showed significant correlation with body weight, BMI, fasting glucose and fasting insulin levels. The association of GGT with fasting insulin and HOMA-IR levels was considerably significant compared to its association with other variables. The serum activity of GGT remained correlated with HOMA-IR even after removing the effect of BMI, weight and age on GGT values. The results showed that GGT is a determinant of HOMA-IR independently of age, BMI and weight. A correlation exists between GGT and insulin resistance markers. The observed correlation indicates that monitoring GGT and fasting insulin levels in obese children might serve to help prevent the development of diabetes in

Using an operational continuum of healthy aging developed by U.S. researchers, we sought to estimate the prevalence of healthy aging among older Spaniards, inform the development of a definition of healthy aging in Spain, and foster cross-national research on healthy aging. The ELES pilot study is a nationwide, cross-sectional survey of community-dwelling Spaniards 50 years and older. The prevalence of healthy aging was calculated for the 65 and over population using varying definitions. To evaluate their validity, we examined the association of healthy aging with the 8 foot up & go test, quality of life scores and self-perceived health using multiple linear and logistic regression. The estimated prevalence of healthy aging varied across the operational continuum, from 4.5% to 49.2%. Prevalence figures were greater for men and those aged 65 to 79 years and were higher than in the United States. Predicted mean physical performance scores were similar for 3 of the 4 definitions, suggesting that stringent definitions of healthy aging offer little advantage over a more moderate one. Similar to U.S. researchers, we recommend a definition of healthy aging that incorporates measures of functional health and limiting disease as opposed to definitions requiring the absence of all disease in studies designed to assess the effect of policy initiatives on healthy aging.

Cerebral palsy (CP) is the most common motor disorder in children. Currently available neuroimaging techniques require complete body confinement and steadiness and thus are extremely difficult for pediatric patients. Here, we report the use and quantification of functional near infrared spectroscopy (fNIRS) to investigate the functional reorganization of the sensorimotor cortex in children with hemiparetic CP. Ten of sixteen children with congenital hemiparesis were measured during finger tapping tasks and compared with eight of sixteen age-matched healthy children, with an overall measurement success rate of 60%. Spatiotemporal analysis was introduced to quantify the motor activation and brain laterality. Such a quantitative approach reveals a consistent, contralateral motor activation in healthy children at 7 years of age or older. In sharp contrast, children with congenital hemiparesis exhibit all three of contralateral, bilateral and ipsilateral motor activations, depending on specific ages of the pediatric subjects. This study clearly demonstrates the feasibility of fNIRS to be utilized for investigating cortical reorganization in children with CP or other cortical disorders. PMID:21164944

Sleep Promotes Consolidation of Emotional Memory in Healthy Children but Not in Children with Attention-Deficit Hyperactivity Disorder

Fronto-limbic brain activity during sleep is believed to support the consolidation of emotional memories in healthy adults. Attention deficit-hyperactivity disorder (ADHD) is accompanied by emotional deficits coincidently caused by dysfunctional interplay of fronto-limbic circuits. This study aimed to examine the role of sleep in the consolidation of emotional memory in ADHD in the context of healthy development. 16 children with ADHD, 16 healthy children, and 20 healthy adults participated in this study. Participants completed an emotional picture recognition paradigm in sleep and wake control conditions. Each condition had an immediate (baseline) and delayed (target) retrieval session. The emotional memory bias was baseline–corrected, and groups were compared in terms of sleep-dependent memory consolidation (sleep vs. wake). We observed an increased sleep-dependent emotional memory bias in healthy children compared to children with ADHD and healthy adults. Frontal oscillatory EEG activity (slow oscillations, theta) during sleep correlated negatively with emotional memory performance in children with ADHD. When combining data of healthy children and adults, correlation coefficients were positive and differed from those in children with ADHD. Since children displayed a higher frontal EEG activity than adults these data indicate a decline in sleep-related consolidation of emotional memory in healthy development. In addition, it is suggested that deficits in sleep-related selection between emotional and non-emotional memories in ADHD exacerbate emotional problems during daytime as they are often reported in ADHD.

To determine normal values for Doppler parameters of left ventricular function, ascending aortic blood flow velocity was measured by pulsed wave Doppler echocardiography in 63 healthy children with body surface area (BSA) < 1 m(2) (age < 10 yr). Peak velocity was independent of sex, but increased with body size. Mean acceleration was related to peak velocity (r = 0.75, p < 0.0001). Both stroke distance and ejection time had strong negative correlations with heart rate and positive correlations with BSA, suggesting that these parameters should be evaluated in relation to heart rate and body size. Mean intra- and interobserver variability for peak velocity, ejection time, stroke and minute distance ranged from 3 to 7%, whereas variability for acceleration time was 9 to 13%. These data may be used as reference values for the assessment of hemodynamic states in young children with cardiac disease. PMID:11306737

We carried out a matched case-control study to analyze the possible association between exposure to the children and the risk of suffering herpes-zoster in adulthood. Cases of herpes zoster in immunocompetent healthy patients aged ≥ 25 years seen in the dermatology department of the Sagrado Corazón Hospital in 2007-2008 were matched with four controls. Data were analyzed using conditional logistic regression. 153 cases and 604 matched controls were included. Contacts with children were significantly associated with a reduction in the risk of suffering herpes zoster in adulthood (adjusted OR 0.56 [0.37-0.85]). Herpes-zoster vaccination in immunocompetent people aged ≥ 50 years could counteract the possible negative effects of mass varicella vaccination in childhood on the epidemiology of herpes zoster in adults.

Approximately one-half of all children will sustain a fracture before adulthood. Understanding the factors that place a child at increased risk of fracture is necessary to inform effective injury prevention strategies. The purpose of this study was to examine the association between temperament and fracture risk in preschool-aged children. Children aged 3 to 6 years who were diagnosed with a fracture were recruited from the Hospital for Sick Children Fracture Clinic. Using a retrospective case-control study design, the 148 cases were frequency-matched by age and sex to 426 controls from the TARGet Kids primary care paediatric cohort. The Childhood Behaviour Questionnaire, a 36-item caregiver response questionnaire was used to assess three of the following temperament factors: surgency (e.g., high activity level), negative affect (e.g., anger, fear, discomfort) and effortful control (e.g., attentional focusing). Unadjusted logistic models demonstrated no association between children with previous fracture and higher scores of surgency (unadjusted odds ratio [OR]=1.06, 95% confidence interval [CI]: 0.84, 1.34), negative affect (unadjusted OR=1.15, 95% CI: 0.93, 1.42) or effortful control (unadjusted OR=0.80, 95% CI: 0.63, 1.03). Further, models adjusted for covariates also demonstrated no significant association with surgency (1.00, 95% CI: 0.78, 1.29), negative affect (1.09, 95% CI: 0.86, 1.37) and effortful control (0.80, 95% CI: 0.61, 1.05). None of the three main temperament types identified by the Childhood Behaviour Questionnaire were associated with an increase in fracture risk.

There is little information regarding age-related reference intervals (RIs) of carotid-femoral pulse wave velocity (cfPWV) for large healthy populations in South America. The aims of this study were to determine cfPWV RIs and percentiles in a cohort of healthy children, adolescents, and adults and to generate year-to-year percentile curves and body-height percentile curves for children and adolescents. cfPWV was measured in 1722 healthy participants with no cardiovascular risk factors (9-87 years, 60% men). First, RIs were evaluated for males and females through correlation and covariate analysis. Then, mean and standard deviation age-related equations were obtained for cfPWV using parametric regression methods based on fractional polynomials and age-specific (year-to-year) percentile curves that were defined using the standard normal distribution. Age-specific first, 2.5th, 5th, 10th, 25th, 50th, 75th, 90th, 95th, 97.5th, and 99th percentile curves were calculated. Finally, height-related cfPWV percentile curves for children and adolescents (<21 years) were established. After adjusting for age and blood pressure differences with respect to females, males showed higher cfPWV levels (6.60 vs 6.45 m/s; P < .01). Thus, specific RIs for males and females were reported. The study provides the largest database to date concerning cfPWV in healthy people from Argentina. Specific RIs and percentiles of cfPWV are now available according to age and sex. Specific percentiles of cfPWV according to body height were reported for people younger than 21 years. ©2018 Wiley Periodicals, Inc.

To compare the optic disc topography parameters of children with juvenile diabetes mellitus and normal children using the Heidelberg Retinal Tomograph (HRT III) (Heidelberg Engineering, Heidelberg, Germany). The topographic optic disc parameters (cup volume, cup area, rim volume, rim area, disc area, mean cup-to-disc ratio, and mean cup depth) of 28 non-glaucomatous eyes of 28 children with type 1 diabetes mellitus and 28 eyes of 28 age-matched healthy children were compared using the nonparametric Mann-Whitney U test. No statistically significant differences were found between cup volume (P = .782), cup area (P = .878), rim volume (P = .853), disc area (P = .452), mean cup-to-disc ratio (P = .852), and mean cup depth (P = .711) of eyes of cases with diabetes mellitus and normal subjects. This result suggests that non-glaucomatous eyes of children with type 1 diabetes mellitus and healthy subjects have similar topographic optic disc characteristics.

Alpha-Klotho (alphaKl) regulates mineral metabolism such as calcium ion (Ca(2+)) and inorganic phosphate (Pi) in circulation. Defects in mice result in clinical features resembling disorders found in human aging. Although the importance of transmembrane-type alphaKl has been demonstrated, less is known regarding the physiological importance of soluble-type alphaKl (salphaKl) in circulation. The aims of this study were: (1) to establish a sandwich ELISA system enabling detection of circulating serum salphaKl, and (2) to determine reference values for salphaKl serum levels and relationship to indices of renal function, mineral metabolism, age and sex in healthy subjects. We successively developed an ELISA to measure serum salphaKl in healthy volunteers (n=142, males 66) of ages (61.1+/-18.5year). The levels (mean+/-SD) in these healthy control adults were as follows: total calcium (Ca; 9.46+/-0.41mg/dL), Pi (3.63+/-0.51mg/dL), blood urea nitrogen (BUN; 15.7+/-4.3mg/dL), creatinine (Cre; 0.69+/-0.14mg/dL), 1,25 dihydroxyvitamin D (1,25(OH)(2)D; 54.8+/-17.7pg/mL), intact parathyroid hormone (iPTH; 49.2+/-20.6pg/mL), calcitonin (26.0+/-12.3pg/mL) and intact fibroblast growth factor (FGF23; 43.8+/-17.6pg/mL). Serum levels of salphaKl ranged from 239 to 1266pg/mL (mean+/-SD; 562+/-146pg/mL) in normal adults. Although salphaKl levels were not modified by gender or indices of mineral metabolism, salphaKl levels were inversely related to Cre and age. However, salphaKl levels in normal children (n=39, males 23, mean+/-SD; 7.1+/-4.8years) were significantly higher (mean+/-SD; 952+/-282pg/mL) than those in adults (mean+/-SD; 562+/-146, P<0.001). A multivariate linear regression analysis including children and adults in this study demonstrated that salphaKl correlated negatively with age and Ca, and positively with Pi. Finally, we measured a serum salphaKl from a patient with severe tumoral calcinosis derived from a homozygous missense mutation of alpha-klotho gene. In this

In order to mitigate childhood obesity, evidence on what influences children's health behaviours is needed to inform new health promotion strategies. The present study investigated the association between parental practices and their child's diet and body weight status. Grade 5 students and their parents completed health surveys. Parents were asked how much they 'encourage their child to eat healthy foods' and how much they 'personally care about healthy eating'. Children's diet quality and vegetable and fruit intake were assessed using an FFQ. Children's heights and weights were measured to determine body weight status. Mixed-effects regression models were used to determine the influence of parental responses on the outcomes of interest. Elementary schools across the province of Alberta, Canada. Grade 5 students (aged 10 and 11 years; n 8388) and their parent(s). Most parents reported caring about healthy eating and encouraging their child to eat healthy foods at least quite a lot. Children whose parents who cared or encouraged 'very much' compared with 'quite a lot' were more likely have better diet quality and were less likely to be overweight. Children whose parents both cared and encouraged 'very much' compared with 'quite a lot' scored an average of 2·06 points higher on the diet quality index (β=2·06; 95 % CI 1·45, 2·66). Health promotion strategies that aim for a high level of parental interest and encouragement of their children to eat healthy foods may improve diet quality and prevent overweight among children.

In this qualitative study, we provide an in-depth understanding of the views of healthy aging among Thai elderly and explore the ways that contribute to healthy aging. Data were collected using focus groups and in-depth interviews in four selected provinces of Thailand, and were analyzed using content analysis. The results revealed that Thai elderly described being healthy as the result of multiple components involving physical, mental, and social well-being. Healthy aging was viewed as an absence of serious diseases, having functional independence, a positive psycho-emotional outlook, and making a social contribution. The factors considered to contribute to healthy aging included activities promoting physical and psychological health, as well as active engagement in social activities. Understanding how the elderly define healthy aging and identifying the most important components and factors that contribute to being healthy provides insight into possible policy implications and interventions to promote health and well-being among Thai elderly. © 2012 Wiley Publishing Asia Pty Ltd.

Does excessive daytime sleepiness affect children's pedestrian safety?

PubMed

Avis, Kristin T; Gamble, Karen L; Schwebel, David C

2014-02-01

Many cognitive factors contribute to unintentional pedestrian injury, including reaction time, impulsivity, risk-taking, attention, and decision-making. These same factors are negatively influenced by excessive daytime sleepiness (EDS), which may place children with EDS at greater risk for pedestrian injury. Using a case-control design, 33 children age 8 to 16 y with EDS from an established diagnosis of narcolepsy or idiopathic hypersomnia (IHS) engaged in a virtual reality pedestrian environment while unmedicated. Thirty-three healthy children matched by age, race, sex, and household income served as controls. Children with EDS were riskier pedestrians than healthy children. They were twice as likely to be struck by a virtual vehicle in the virtual pedestrian environment than healthy controls. Attentional skills of looking at oncoming traffic were not impaired among children with EDS, but decision-making for when to cross the street safely was significantly impaired. Results suggest excessive daytime sleepiness (EDS) from the clinical sleep disorders known as the hypersomnias of central origin may have significant consequences on children's daytime functioning in a critical domain of personal safety, pedestrian skills. Cognitive processes involved in safe pedestrian crossings may be impaired in children with EDS. In the pedestrian simulation, children with EDS appeared to show a pattern consistent with inattentional blindness, in that they "looked but did not process" information in their pedestrian environment. Results highlight the need for heightened awareness of potentially irreversible consequences of untreated sleep disorders and identify a possible target for pediatric injury prevention.

The consequences of influenza in children and adults are mainly absenteeism from school and work. However, the risk of complications is greatest in children and people over 65 years of age. This is an update of a review published in 2011. Future updates of this review will be made only when new trials or vaccines become available. Observational data included in previous versions of the review have been retained for historical reasons but have not been updated because of their lack of influence on the review conclusions. To assess the effects (efficacy, effectiveness, and harm) of vaccines against influenza in healthy children. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2016, Issue 12), which includes the Cochrane Acute Respiratory Infections Group Specialised Register, MEDLINE (1966 to 31 December 2016), Embase (1974 to 31 December 2016), WHO International Clinical Trials Registry Platform (ICTRP; 1 July 2017), and ClinicalTrials.gov (1 July 2017). Randomised controlled trials comparing influenza vaccines with placebo or no intervention in naturally occurring influenza in healthy children under 16 years. Previous versions of this review included 19 cohort and 11 case-control studies. We are no longer updating the searches for these study designs but have retained the observational studies for historical purposes. Review authors independently assessed risk of bias and extracted data. We used GRADE to rate the certainty of evidence for the key outcomes of influenza, influenza-like illness (ILI), complications (hospitalisation, ear infection), and adverse events. Due to variation in control group risks for influenza and ILI, absolute effects are reported as the median control group risk, and numbers needed to vaccinate (NNVs) are reported accordingly. For other outcomes aggregate control group risks are used. We included 41 clinical trials (> 200,000 children). Most of the studies were conducted in children over the

Perceptions of competence: age moderates views of healthy aging and Alzheimer's disease.

BACKGROUND/STUDY CONTEXT: Older adults have more complex and differentiated views of aging than do younger adults, but less is known about age-related perceptions of Alzheimer's disease. This study investigated age-related perceptions of competence of an older adult labeled as "in good health" (healthy) or "has Alzheimer's disease" (AD), using a person-perception paradigm. It was predicted that older adults would provide more differentiated assessments of the two targets than would younger adults. Younger (n=86; 18-36 years) and older (n=66; 61-95 years) adults rated activities of daily living (ADL), instrumental activities of daily living (IADL), and memory abilities of a female target aged 75 years, described as healthy or with AD. Data on anxiety about aging, knowledge of and experience with aging and AD, knowledge of memory aging, and positive and negative biases toward aging and AD were also collected. Older adults perceived the healthy target as more capable of cognitively effortful activities (e.g., managing finances) and as possessing better memory abilities than the AD target. As predicted, these differences were greater than differences between targets perceived by younger adults. The interaction effect remained significant after statistically controlling for relevant variables, including education and gender. Additionally, exploratory analyses revealed that older adults held less positively biased views of AD than younger adults, but negatively biased views were equivalent between age groups. The results demonstrate that mere labels of "healthy" and "Alzheimer's disease" produce significant and subtle age differences in perceived competencies of older adults, and that biases towards AD vary by age group and valence. Our findings extend the person-perception paradigm to an integrative analysis of aging and AD, are consistent with models of adult development, and complement current research and theory on stereotypes of aging.

The sleep of children with attention deficit hyperactivity disorder on and off methylphenidate: a matched case-control study.

PubMed

Galland, Barbara C; Tripp, E Gail; Taylor, Barry J

2010-06-01

In the present study, we assessed the effects of regular use of methylphenidate medication in children diagnosed with attention deficit hyperactivity disorder (ADHD) on sleep timing, duration and sleep architecture. Twenty-seven children aged 6-12 years meeting diagnostic criteria for Diagnostic and Statistical Manual version IV ADHD and 27 control children matched for age (+/-3 months) and gender. Two nights of standard polysomnographic (PSG) recordings were conducted. ADHD children were allocated randomly to an on- or 48 h off-methylphenidate protocol for first or second recordings. Control children's recordings were matched for night, but no medication was used. Mixed modelling was employed in the analyses so that the full data set was used to determine the degree of medication effects. Methylphenidate in ADHD children prolonged sleep onset by an average of 29 min [confidence interval (CI) 11.6, 46.7], reduced sleep efficiency by 6.5% (CI 2.6, 10.3) and shortened sleep by 1.2 h (CI 0.65, 1.9). Arousal indices were preserved. Relative amounts of stages 1, 2 and slow wave sleep were unchanged by medication. Rapid eye movement sleep was reduced (-2.4%) on the medication night, an effect that became non-significant when control data were incorporated in the analyses. PSG data from ADHD children off-medication were similar to control data. Our findings suggest that methylphenidate reduces sleep quantity but does not alter sleep architecture in children diagnosed with ADHD. An adequate amount of sleep is integral to good daytime functioning, thus the sleep side effects of methylphenidate may affect adversely the daytime symptoms the drug is targeted to control.

To examine autonomy-promoting parenting and independent problem-solving in children with food allergy. 66 children with food allergy, aged 3-6 years, and 67 age-matched healthy peers and their mothers were videotaped while completing easy and difficult puzzles. Coders recorded time to puzzle completion, children's direct and indirect requests for help, and maternal help-giving behaviors. Compared with healthy peers, younger (3- to 4-year-old) children with food allergy made more indirect requests for help during the easy puzzle, and their mothers were more likely to provide unnecessary help (i.e., explain where to place a puzzle piece). Differences were not found for older children. The results suggest that highly involved parenting practices that are medically necessary to manage food allergy may spill over into settings where high levels of involvement are not needed, and that young children with food allergy may be at increased risk for difficulties in autonomy development. © The Author 2014.

A treat for the eyes. An eye-tracking study on children's attention to unhealthy and healthy food cues in media content.

Spielvogel, Ines; Matthes, Jörg; Naderer, Brigitte; Karsay, Kathrin

2018-06-01

Based on cue reactivity theory, food cues embedded in media content can lead to physiological and psychological responses in children. Research suggests that unhealthy food cues are represented more extensively and interactively in children's media environments than healthy ones. However, it is not clear to this date whether children react differently to unhealthy compared to healthy food cues. In an experimental study with 56 children (55.4% girls; M age  = 8.00, SD = 1.58), we used eye-tracking to determine children's attention to unhealthy and healthy food cues embedded in a narrative cartoon movie. Besides varying the food type (i.e., healthy vs. unhealthy), we also manipulated the integration levels of food cues with characters (i.e., level of food integration; no interaction vs. handling vs. consumption), and we assessed children's individual susceptibility factors by measuring the impact of their hunger level. Our results indicated that unhealthy food cues attract children's visual attention to a larger extent than healthy cues. However, their initial visual interest did not differ between unhealthy and healthy food cues. Furthermore, an increase in the level of food integration led to an increase in visual attention. Our findings showed no moderating impact of hunger. We conclude that especially unhealthy food cues with an interactive connection trigger cue reactivity in children. Copyright © 2018 Elsevier Ltd.

2009-11-01

Lead poisoning is a potentially devastating problem among young children. Chronic low level lead exposure can lead to learning disabilities and behavior changes such as colic, insomnia, hyperactivity, impaired growth, hearing loss and upper extremity weakness. The purpose of this cross sectional study was to determine the blood lead level in children with neurological disorders in comparison with healthy controls. Blood lead concentrations were measured by flame atomic absorption spectrometry in 100 children aged 1-10 years and suffering from various neurological disorders. One hundred age and sex-matched healthy children served as controls. The mean blood lead concentration was higher in children with neurological disorders than in controls (113.2 + or - 47.5 microg/L vs 84.7 + or - 38.0 microg/L; p<0.01). Overall, 44% of children with neurological disorders and 19% of controls were found to have increased blood lead levels, i.e.>100 microg/L. An increase in blood lead level in children might be related to neurological disorders. The measurement of blood lead level might be included in diagnostic eveluation of children with neurological disorders.

Abstract Schult, Sandra, and Carlos Canelo-Aybar. Oxygen saturation in healthy chidren aged 5 to 6 years residing in Huayllay, Peru, at 4340 m. High Alt. Med. Biol. 12:89–92, 2011.—Hypoxemia is a major life-threatening complication of childhood pneumonia. The threshold points for hypoxemia vary with altitude. However, few published data describe that normal range of variation. The purpose of this study was to establish reference values of normal mean Sao2 levels and an approximate cutoff point to define hypoxemia for clinical purposes above 4300 meters above sea level (masl). Children aged 5 to 16 yr were examined during primary care visits at the Huayllay Health Center. Huayllay is a rural community located at 4340 m in the province of Pasco in the Peruvian Andes. We collected basic sociodemographic data and evaluated three outcomes: arterial oxygen saturation (Sao2) with a pulse oximeter, heart rate, and respiratory rate. Comparisons of main outcomes among age groups (5–6, 7–8, 9–10, 11–12, 13–14, and 15–16 yr) and sex were performed using linear regression models. The correlation of Sao2 with heart rate and respiration rate was established by Pearson's correlation test. We evaluated 583 children, of whom 386 were included in the study. The average age was 10.3 yr; 55.7% were female. The average Sao2, heart rate, and respiratory rate were 85.7% (95% CI: 85.2–86.2), 80.4/min (95% CI: 79.0–81.9), and 19.9/min (95% CI: 19.6–20.2), respectively. Sao2 increased with age (p < 0.001). No differences by sex were observed. The mean minus two standard deviations of Sao2 (threshold point for hypoxemia) ranged from 73.8% to 81.8% by age group. At 4300 m, the reference values for hypoxemia may be 14.2% lower than at sea level. This difference must be considered when diagnosing hypoxemia or deciding oxygen supplementation at high altitude. Other studies are needed to determine whether this reference value is appropriate for clinical use. PMID

Mastery motivation is a precursor of future developmental outcomes. Evidence about whether toddlers with motor delay have lower mastery motivation is inconclusive. The purpose of this study was to examine differences between mental age-matched toddlers with and without motor delay on various mastery motivation indicators. A mental age- and sex-matched case-control study was performed. Twenty-two children with motor delay, aged 23 to 47 months, and 22 children who were developing typically, aged 15 to 29 months, were recruited. Persistence and mastery pleasure were measured with behavioral tasks that were moderately challenging for each child and with maternal ratings using the Dimensions of Mastery Questionnaire (DMQ). The DMQ was rated by each child's mother based on her perception of her child's motivation. Two types of structured tasks (a puzzle and a cause-effect toy selected to be moderately challenging for each child) were administered in a laboratory setting and recorded on videos. Paired t tests or Wilcoxon signed rank tests were used to examine group differences in persistence and mastery pleasure (α=.007, 2-tailed). Children with motor delay were rated lower on DMQ persistence than the typically developing group, but they did not show significantly lower persistence on the structured tasks. There were no significant differences in mastery pleasure between the 2 groups on either measure. Large within-sample variability on the tasks and small sample size makes subgroup analysis (eg, different severities) difficult. Toddlers with motor delay did not show lower persistence and pleasure when given tasks that were moderately challenging; however, their mothers tended to view them as having lower motivation. Clinicians and parents should provide appropriately challenging tasks to increase children's success and motivation.

The Healthy Aging Research Network: Modeling Collaboration for Community Impact.

As the first Centers for Disease Control and Prevention (CDC) Prevention Research Centers Program thematic network, the Healthy Aging Research Network was established to better understand the determinants of healthy aging within older adult populations, identify interventions that promote healthy aging, and assist in translating research into sustainable community-based programs throughout the nation. To achieve these goals requires concerted efforts of a collaborative network of academic, community, and public health organizational partnerships. For the 2001-2014 Prevention Research Center funding cycles, the Healthy Aging Research Network conducted prevention research and promoted the wide use of practices known to foster optimal health. Organized around components necessary for successful collaborations (i.e., governance and infrastructure, shaping focus, community involvement, and evaluation and improvement), this commentary highlights exemplars that demonstrate the Healthy Aging Research Network's unique contributions to the field. The Healthy Aging Research Network's collaboration provided a means to collectively build capacity for practice and policy, reduce fragmentation and duplication in health promotion and aging research efforts, maximize the efficient use of existing resources and generate additional resources, and ultimately, create synergies for advancing the healthy aging agenda. This collaborative model was built upon a backbone organization (coordinating center); setting of common agendas and mutually reinforcing activities; and continuous communications. Given its successes, the Healthy Aging Research Network model could be used to create new and evaluate existing thematic networks to guide the translation of research into policy and practice.

Luther, Brenda L; Christian, Becky J

2017-01-01

To gain insight into how parents develop their beliefs of health promotion for their children with spina bifida (SB) and how they develop and promote health promotion practices for their children. Qualitative, exploratory design with semi-structured interviews of parents of children between 6 and 12 years of age diagnosed with SB was used for this study. Perceptions of health promotion were maintaining healthy bowel function and managing SB care. Good bowel function and SB management is health promotion and adequate bowel function is viewed as a marker of health. Maintaining healthy bowel function was identified by parents as the key marker of health for their children with SB. Further, the term health promotion brought up plans, concerns, and goals more related to their child's physiologic functioning and health care needs rather than promoting health and avoiding preventable disease. Nurses and healthcare providers are in unique and powerful positions for strategizing with parents on how to integrate health promotion into the lives of children with SB. Team-based, whole-person, holistic assessment and teaching inclusive of promoting healthy lifestyle behaviors in addition to providing excellent care related to their physiologic systems affected by SB can improve how we promote health for these children. © 2017 Wiley Periodicals, Inc.

Stunting remains a major public health concern worldwide. Although its global prevalence is slowly decreasing, the actual number of affected children is still rising in Sub-Saharan Africa. In the Central African Republic (CAR), about one third of all children below the age of five are stunted. Stunting is correlated with many long-term consequences, including poor cognitive development and a higher rate of morbidity and mortality, making stunting a major contributor to poverty. In CAR, little is known about the factors that contribute to stunting. This study aimed at analysing, in a cross-sectional study, the main factors associated with stunting in a group of 414 children recruited between December 2011 and November 2013, aged five years or less and living in Bangui. For all children, demographic, socio-economic and anthropometric data were recorded and asymptomatic enteropathogen carriage was assessed in stool samples using classical microbiological assays. The study group had a mean age of 14.2±10 months. Fifty-eight percent (292/414) were boys, and 36 percent (148/414) exhibited stunted growth. Of the stunted children, 51% (75/148) showed a moderate delay in linear growth for their age group [height-for-age z-score (HAZ) between -2 and -3 SD] while 49% (73/148) presented a severe delay (HAZ < -3). Factors significantly associated with stunting included gender (aOR: 1.67; 95% CI: 1.07; 2.62 for boys compared to girls) and age (aOR of 3.98 (95% CI: 2.45; 6.46) for toddlers and aOR 4.42 (95% CI: 2.36; 8.28) for children compared to infants). Most importantly, we identified being overweight [weight-for-height z-score (WHZ) > 2 SD; aOR: 3.21; 95% CI: 1.50; 6.90 of overweight compared to normal weight] as also being significantly associated with stunting. This is the first study showing that even in the poorest countries of the world there is an association of stunting with being overweight.

To determine whether motor development at 3 months of age is associated with cognitive, motor, and behavioural outcomes in healthy children at early school age. In this cohort study, we included 74 term-born, healthy children (44 males, 30 females; median gestational age 40.1 wks, range 38.0-42.6 wks). From video recordings (median 12.9 wks, range 9.3-18.6 wks), we assessed the quality of fidgety movements, and calculated a motor optimality score. At school age (median 5 y 11 mo, range 5 y 8 mo-7 y 6 mo), we performed detailed cognitive, motor, and behavioural assessments. We examined whether aspects of motor development were associated with functional outcomes. An age-adequate motor repertoire, in particular the presence of antigravity, midline leg, and manipulation movements, was related to poorer cognition, whereas variable finger postures was related to better cognition. Children with a monotonous concurrent motor repertoire had better ball skills but experienced more behavioural problems. The presence of antigravity movements tended to be associated with abnormal recognition (odds ratio [OR] 4.4, 95% confidence interval [CI], 0.9-21; R(2) =0.17; p=0.070), where the absence of variable finger postures was associated with borderline and abnormal visual-spatial perception (OR 20, 95% CI, 1.7-238; R(2) =0.39; p=0.018). Detailed aspects of motor development at 3 months of age are associated with cognition and behaviour, but not with motor outcome, in healthy children at early school age. Our findings suggest that early motor development may be the basis for later cognitive and behavioural performance. Since the associations were only moderate, possible environmental influences should be acknowledged. © 2014 Mac Keith Press.

The American Heart Association created Go Red Heart Match, a free and secure online program that enables women to connect with each other to fight heart disease either personally or as a caregiver for someone with heart disease. Through these connections, participants have an opportunity to develop a personal, private, and supportive relationship with other women; share common experiences; and motivate and encourage each other to follow a heart-healthy lifestyle. The aims of this study were to describe the demographic characteristics of the Go Red Heart Match responders and to determine whether participation in the program prompted participants to engage in heart-healthy behaviors. A secondary analysis of data collected as part of a needs assessment survey from the American Heart Association Go Red Heart Match was conducted. A total of 117 (35%) of the 334 invited women completed the survey. Most responders were female, married, and college educated. A total of 105 (90%) responders were diagnosed with a type of heart disease or stroke and 77 (73%) responders had undergone treatment. As a result of participating in the program, 75% of the responders reported the following improvements in heart-healthy behaviors: eating a more heart-healthy diet (54%), exercising more frequently (53%), losing weight (47%), and quitting smoking (10%). Responders who had a diagnosis of heart attack (n = 48) were more likely (P = .003) to quit smoking than were those with other diagnoses (n = 69). Notably, 48% of responders reported encouraging someone else in their life to speak to their doctor about their risk for heart disease. Most women who participated in Heart Match reported engaging in new heart-healthy behaviors. The findings support expanding the existing program in a more diverse population as a potentially important way to reach women and encourage cardiovascular disease risk reduction for those with heart disease and stroke.

The link between brain structure and intelligence is a well-investigated topic, but existing analyses have mainly focused on adult samples. Studies in healthy children and adolescents are rare, and normative data specifically addressing the association between corpus callosum morphology and intellectual abilities are quite limited. To advance this field of research, we mapped the correlations between standardized intelligence measures and callosal thickness based on high-resolution magnetic resonance imaging (MRI) data. Our large and well-matched sample included 200 normally developing subjects (100 males, 100 females) ranging from 6 to 17 years of age. Although the strongest correlations were negative and confined to the splenium, the strength and the direction of intelligence-callosal thickness associations varied considerably. While significant correlations in females were mainly positive, significant correlations in males were exclusively negative. However, only the negative correlations in the overall sample (i.e., males and females combined) remained significant when controlling for multiple comparisons. The observed negative correlations between callosal thickness and intelligence in children and adolescents contrast with the positive correlations typically reported in adult samples. However, negative correlations are in line with reports from other pediatric studies relating cognitive measures to other brain attributes such as cortical thickness, gray matter volume, and gray matter density. Altogether, these findings suggest that relationships between callosal morphology and cognition are highly dynamic during brain maturation. Sex effects on links between callosal thickness and intelligence during childhood and adolescence are present but appear rather weak in general. Copyright © 2010 Elsevier Inc. All rights reserved.

Laryngeal Aerodynamics in Children with Hearing Impairment versus Age and Height Matched Normal Hearing Peers.

Das, Barshapriya; Chatterjee, Indranil; Kumar, Suman

2013-01-01

Lack of proper auditory feedback in hearing-impaired subjects results in functional voice disorder. It is directly related to discoordination of intrinsic and extrinsic laryngeal muscles and disturbed contraction and relaxation of antagonistic muscles. A total of twenty children in the age range of 5-10 years were considered for the study. They were divided into two groups: normal hearing children and hearing aid user children. Results showed a significant difference in the vital capacity, maximum sustained phonation, and fast adduction abduction rate having equal variance for normal and hearing aid user children, respectively, but no significant difference was found in the peak flow value with being statistically significant. A reduced vital capacity in hearing aid user children suggests a limited use of the lung volume for speech production. It may be inferred from the study that the hearing aid user children have poor vocal proficiency which is reflected in their voice. The use of voicing component in hearing impaired subjects is seen due to improper auditory feedback. It was found that there was a significant difference in the vital capacity, maximum sustained phonation (MSP), and fast adduction abduction rate and no significant difference in the peak flow.

Children with autism spectrum disorders (ASD) often present with emotional and behavioral problems, which could change the clinical course, especially during childhood, and affect future quality of life. The aim of this study was to clarify the age- and sex-related differences of these problems in ASD. The study subjects were 173 patients with ASD (age: 4-16 years) and 173 age- and sex-matched community children (control group). The parent version of the Strengths and Difficulties Questionnaire was used for comparison of the emotional and behavioral problems between the two groups. The Strengths and Difficulties Questionnaire scores were significantly higher in children with ASD than controls at all ages. The score of total difficulties was significantly higher in girls with ASD than in boys, while the score in male controls was significantly higher than in female controls. Age-related differences in emotional and behavioral problems were observed both in children with ASD and controls, but the characteristics were different: in children with ASD, emotional symptoms and peer problems in both sexes and conduct problems in girls increased significantly with age, while none of the problems in the controls changed with age except for a decrease in the score of hyperactivity/inattention developmentally in both sexes. Prosocial behaviors of children with ASD and controls showed small changes with age. Emotional and behavioral problems are common in children with ASD and showed age- and sex-related differences. Our study emphasizes the importance of recognizing those differences among children with ASD for early intervention. © 2014 The Authors.

2016-01-01

Phonemic accuracy of children with cochlear implants (CI) is often reported to be lower in comparison with normally hearing (NH) age-matched children. In this study, we compare phonemic accuracy development in the spontaneous speech of Dutch-speaking children with CI and NH age-matched peers. A dynamic cost model of Levenshtein distance is used to compute the accuracy of each word token. We set up a longitudinal design with monthly data for comparisons up to age two and a cross-sectional design with yearly data between three and five years of age. The main finding is that phonemic accuracy steadily increases throughout the period studied. Children with CI's accuracy is lower than that of their NH age mates, but this difference is not statistically significant in the earliest stages of lexical development. But accuracy of children with CI initially improves significantly less steeply than that of NH peers. Furthermore, the number of syllables in the target word and target word's complexity influence children's accuracy, as longer and more complex target words are less accurately produced. Up to age four, children with CI are significantly less accurate than NH children with increasing word length and word complexity. This difference has disappeared at age five. Finally, hearing age is shown to influence accuracy development of children with CI, while age of implant activation is not. This article informs the reader about phonemic accuracy development in children. The reader will be able to (a) discuss different metrics to measure phonemic accuracy development, (b) discuss phonemic accuracy of children with CI up to five years of age and compare them with NH children, (c) discuss the influence of target word's complexity and target word's syllable length on phonemic accuracy, (d) discuss the influence of hearing experience and age of implantation on phonemic accuracy of children with CI.

Background Childhood falls result in considerable morbidity, mortality and health service use. Despite this, little evidence exists on protective factors or effective falls prevention interventions in young children. Objectives To estimate ORs for three types of medically attended fall injuries in young children in relation to safety equipment, safety behaviours and hazard reduction and explore differential effects by child and family factors and injury severity. Design Three multicentre case–control studies in UK hospitals with validation of parental reported exposures using home observations. Cases are aged 0–4 years with a medically attended fall injury occurring at home, matched on age and sex with community controls. Children attending hospital for other types of injury will serve as unmatched hospital controls. Matched analyses will use conditional logistic regression to adjust for potential confounding variables. Unmatched analyses will use unconditional logistic regression, adjusted for age, sex, deprivation and distance from hospital in addition to other confounders. Each study requires 496 cases and 1984 controls to detect an OR of 0.7, with 80% power, 5% significance level, a correlation between cases and controls of 0.1 and a range of exposure prevalences. Main outcome measures Falls on stairs, on one level and from furniture. Discussion As the largest in the field to date, these case control studies will adjust for potential confounders, validate measures of exposure and investigate modifiable risk factors for specific falls injury mechanisms. Findings should enhance the evidence base for falls prevention for young children. PMID:22628151

Improving self-esteem, dietary habits, and physical activity is essential for long-term success in childhood obesity prevention. The aim is to evaluate the effects of a healthy living promotion program, Healthy Kids-Houston, on BMI, dietary habits, self-esteem, and physical activity among minority children. The after-school program was implemented at community centers in low-income neighborhoods with close proximity to public schools. The program consisted of 3 6-week sessions. Each week, children attended 2 2-hour sessions. Each 2-hour session in the intervention included 90 minutes of structured physical activities and 30 minutes of nutrition and healthy habit lessons. The control group received typical enrichment programs. Outcomes were measured before the intervention and at the end of each 6-week session. We enrolled 877 children (age 10.2 ± 0.1 years (mean ± SE); body mass index z score: 1.49 ± 0.1; 52.0% boys; 72.6% Hispanic) in the program with 524 children received the intervention at 14 community centers and 353 children served as control at 10 community centers. The intervention led to no improvements in BMI z score (P = 0.78) and dietary habits (P = 0.46). Significant improvements (P ≤ 0.02) were detected in the amount of exercise that a child perceived to be required to offset a large meal and in several key self-esteem scores. No improvements were detected in physical activities (P ≥ 0.21). The improvement in some key self-esteem scores and nutrition knowledge may act as a mediator to motivate these children to adopt a healthier lifestyle in the future.

Brain-computer interfaces (BCIs) aimed at restoring communication to people with severe neuromuscular disabilities often use event-related potentials (ERPs) in scalp-recorded EEG activity. Up to the present, most research and development in this area has been done in the laboratory with young healthy control subjects. In order to facilitate the development of BCI most useful to people with disabilities, the present study set out to: (1) determine whether people with amyotrophic lateral sclerosis (ALS) and healthy, age-matched volunteers (HVs) differ in the speed and accuracy of their ERP-based BCI use; (2) compare the ERP characteristics of these two groups; and (3) identify ERP-related factors that might enable improvement in BCI performance for people with disabilities. Sixteen EEG channels were recorded while people with ALS or healthy age-matched volunteers (HVs) used a P300-based BCI. The subjects with ALS had little or no remaining useful motor control (mean ALS Functional Rating Scale-Revised 9.4 (±9.5SD) (range 0-25)). Each subject attended to a target item as the items in a 6×6 visual matrix flashed. The BCI used a stepwise linear discriminant function (SWLDA) to determine the item the user wished to select (i.e., the target item). Offline analyses assessed the latencies, amplitudes, and locations of ERPs to the target and non-target items for people with ALS and age-matched control subjects. BCI accuracy and communication rate did not differ significantly between ALS users and HVs. Although ERP morphology was similar for the two groups, their target ERPs differed significantly in the location and amplitude of the late positivity (P300), the amplitude of the early negativity (N200), and the latency of the late negativity (LN). The differences in target ERP components between people with ALS and age-matched HVs are consistent with the growing recognition that ALS may affect cortical function. The development of BCIs for use by this population may begin

Both animal and human studies have suggested that prenatal opioid exposure may be detrimental to the developing fetal brain. However, results are somewhat conflicting. Structural brain changes in children with prenatal opioid exposure have been reported in a few studies, and such changes may contribute to neuropsychological impairments observed in exposed children. To investigate the association between prenatal opioid exposure and brain morphology in school-aged children. A cross-sectional magnetic resonance imaging (MRI) study of prenatally opioid-exposed children and matched controls. A hospital-based sample (n=16) of children aged 10-14years with prenatal exposure to opioids and 1:1 sex- and age-matched unexposed controls. Automated brain volume measures obtained from T1-weighted MRI scans using FreeSurfer. Volumes of the basal ganglia, thalamus, and cerebellar white matter were reduced in the opioid-exposed group, whereas there were no statistically significant differences in global brain measures (total brain, cerebral cortex, and cerebral white matter volumes). In line with the limited findings reported in the literature to date, our study showed an association between prenatal opioid exposure and reduced regional brain volumes. Adverse effects of opioids on the developing fetal brain may explain this association. However, further research is needed to explore the causal nature and functional consequences of these findings.

We sought to combine parental and child reports in order to describe the behavior, self-perception, and emotional profile of children with a surgically corrected congenital heart disease (CHD). Forty-three children with a surgically corrected CHD were selected and compared to an age- and sex-matched healthy group. The parents of the CHD children completed a behavior rating scale, the Child Behavior Checklist. Children 8 years and older (n = 23) completed a self-report questionnaire concerning perceived competence, their anxiety level, and feelings of depression. Compared to parents of healthy children, those of CHD children report significantly lower school results (p < .01), more school problems in general (p < .01), and a higher percentage of their children repeated a school year (p < .01). They also reported more social (p < .01) and attention problems (p < .01) and more aggressive behavior (p < .05). On self-perception and state anxiety questionnaires, no significant differences were found between the patient group and the healthy group. On a depression scale, however, children with a surgically corrected CHD reported more depressive feelings than healthy controls (p < .01). Parents of children with CHD rate their child's school competence to be weaker than healthy peers, they report more attention and social problems and more aggressive behavior. Children themselves did not report differences on perceived competence or anxiety but they do indicate more depressive symptoms than healthy peers.

Little is known about the influence of advertising on very young children. We, therefore, measured product logo recognition by subjects aged 3 to 6 years. Children were instructed to match logos with one of 12 products pictured on a game board. Twenty-two logos were tested, including those representing children's products, adult products, and those for two popular cigarette brands (Camel and Marlboro). Preschools in Augusta and Atlanta, Ga. A convenience sample of 229 children attending preschool. The children demonstrated high rates of logo recognition. When analyzed by product category, the level of recognition of cigarette logos was intermediate between children's and adult products. The recognition rates of The Disney Channel logo and Old Joe (the cartoon character promoting Camel cigarettes) were highest in their respective product categories. Recognition rates increased with age. Approximately 30% of 3-year-old children correctly matched Old Joe with a picture of a cigarette compared with 91.3% of 6-year-old children. Very young children see, understand, and remember advertising. Given the serious health consequences of smoking, the exposure of children to environmental tobacco advertising may represent an important health risk and should be studied further.

Background Considerable evidence suggests that performance across a variety of cognitive tasks is effectively supported by the use of verbal and nonverbal strategies. Studies exploring the usefulness of such strategies in children with specific language impairment (SLI) are scarce and report inconsistent findings. Aim The present study examined effects of induced labelling and auditory cues on the performance of children with and without SLI during a categorization task. Methods & Procedures Sixty-six school-age children (22 with SLI, 22 age-matched controls, 22 language-matched controls) completed three versions of a computer-based categorization task: one baseline, one requiring overt labelling, and one with auditory cues (tones) on randomized trial blocks. Outcomes & Results Labelling had no effect on performance for typically developing children but resulted in lower accuracy and longer reaction time in children with SLI. The presence of tones had no effect on accuracy but resulted in faster reaction time and post-error slowing across groups. Conclusions & Implications Verbal strategy use was ineffective for typically developing children and negatively affected children with SLI. All children showed faster performance and increased performance monitoring as a result of tones. Overall, effects of strategy use in children appear to vary based on task demands, strategy domain, age, and language ability. Results suggest that children with SLI may benefit from auditory cues in their clinical intervention but that further research is needed to determine when and how verbal strategies might similarly support performance in this population.

Severe fatigue after treatment of ductal carcinoma in situ (DCIS) has not been studied before. The current study examined (i) the prevalence of severe fatigue in DCIS patients versus breast cancer survivors (BCS) and healthy controls (HC), (ii) quality of life and functioning of severely versus non-severely fatigued DCIS patients and BCS, and (iii) the association of fatigue with psychosocial and behavioral factors in DCIS patients. 89 patients treated for DCIS were matched on age and gender to 67 BCS and 178 HC (ratio 1:1:2). Fatigue was measured with the Fatigue Severity subscale of the Checklist Individual Strength. 23% of DCIS patients, 25% of BCS, and 6% of HC were severely fatigued (DCIS versus HC: p < 0.001). Severely fatigued DCIS patients had a lower quality of life and were more impaired in all domains of functioning than non-severely fatigued DCIS patients. Sleep problems, dysfunctional cognitions regarding fatigue, avoidance of activities, all-or-nothing behavior, perceived lack of social support, DCIS-related coping problems, and fear of future cancer occurrence were related to fatigue. The prevalence of severe fatigue in DCIS patients was similar to BCS, but higher than in HC. Severely fatigued DCIS patients had a lower quality of life and more functional impairments. The psychosocial and behavioral fatigue-related factors in DCIS patients are known to perpetuate fatigue in BCS. These factors can be targeted in interventions for cancer-related fatigue. Our findings suggest that the same treatment elements might be applicable to severely fatigued DCIS patients. Copyright © 2016 Elsevier Ltd. All rights reserved.

To compare MRI-based functional pulmonary and cardiac measurements in the long-term follow-up of children operated on for left-sided congenital diaphragmatic hernia (CDH) with age- and body size-matched healthy controls. Twelve children who received immediate postnatal surgery for closure of isolated left-sided CDH were included and received basic medical examinations, pulmonary function testing and echocardiography. MRI included measurement of lung volume, ventricular function assessment and velocity-encoded imaging of the pulmonary arteries and was compared with the data for 12 healthy children matched for age and body size. While patients' clinical test results were not suspicious, comparison between the MRI data for patients and those for healthy controls revealed significant differences. In patients, the volumes of the left lungs were increased and the tidal volume was larger on the right side. While the stroke volumes of both ventricles were reduced, heart rate and ejection fraction were increased. Flow, acceleration time and cross-sectional area of the left pulmonary artery were reduced. Functional MRI detected pulmonary and cardiac findings in the late follow-up of CDH children which may be missed by standard clinical methods and might be relevant for decisions regarding late outcome and treatment.

Most physical activity and nutrition interventions in children focus on the school setting; however, evidence suggests that children are less active and have greater access to unhealthy food at home. The aim of this pilot study was to examine the efficacy of a compulsory homework programme for increasing physical activity and healthy eating in children. The six-week 'Healthy Homework' programme and complementary teaching resource was developed under the guidance of an intersectoral steering group. Eight senior classes (year levels 5-6) from two diverse Auckland primary schools were randomly assigned into intervention and control groups. A total of 97 children (57 intervention, 40 control) aged 9-11 years participated in the evaluation of the intervention. Daily step counts were monitored immediately before and after the intervention using sealed multiday memory pedometers. Screen time, sports participation, active transport to and from school, and the consumption of fruits, vegetables, unhealthy foods and drinks were recorded concurrently in a 4-day food and activity diary. Healthy Homework resulted in a significant intervention effect of 2,830 steps.day-1 (95% CI: 560, 5,300, P = 0.013). This effect was consistent between sexes, schools, and day types (weekdays and weekend days). In addition, significant intervention effects were observed for vegetable consumption (0.83 servings.day-1, 95% CI: 0.24, 1.43, P = 0.007) and unhealthy food consumption (-0.56 servings.day-1, 95% CI: -1.05, -0.07, P = 0.027) on weekends but not weekdays, with no interactions with sex or school. Effects for all other variables were not statistically significant regardless of day type. Compulsory health-related homework appears to be an effective approach for increasing physical activity and improving vegetable and unhealthy food consumption in children. Further research in a larger study is required to confirm these initial results.

Increases in life expectancy make it important to remain healthy for as long as possible. Our objective was to examine the extent to which healthy behaviours in midlife, separately and in combination, predict successful aging. We used a prospective cohort design involving 5100 men and women aged 42-63 years. Participants were free of cancer, coronary artery disease and stroke when their health behaviours were assessed in 1991-1994 as part of the Whitehall II study. We defined healthy behaviours as never smoking, moderate alcohol consumption, physical activity (≥ 2.5 h/wk moderate physical activity or ≥ 1 h/wk vigorous physical activity), and eating fruits and vegetables daily. We defined successful aging, measured over a median 16.3-year follow-up, as good cognitive, physical, respiratory and cardiovascular functioning, in addition to the absence of disability, mental health problems and chronic disease (coronary artery disease, stroke, cancer and diabetes). At the end of follow-up, 549 participants had died and 953 qualified as aging successfully. Compared with participants who engaged in no healthy behaviours, participants engaging in all 4 healthy behaviours had 3.3 times greater odds of successful aging (95% confidence interval [CI] 2.1-5.1). The association with successful aging was linear, with the odds ratio (OR) per increment of healthy behaviour being 1.3 (95% CI 1.2-1.4; population-attributable risk for 1-4 v. 0 healthy behaviours 47%). When missing data were considered in the analysis, the results were similar to those of our main analysis. Although individual healthy behaviours are moderately associated with successful aging, their combined impact is substantial. We did not investigate the mechanisms underlying these associations, but we saw clear evidence of the importance of healthy behaviours for successful aging.

The purposes of this study were to examine the performance on the progressive aerobic cardiovascular endurance run (PACER) test in children with and without attention-deficit hyperactive disorder (ADHD) over the course of a school year, and also to investigate the possible influence of age, sex, school sport participation, and body mass index on results. Utilizing a repeated measures design, 892 middle school children aged 11-14 years (mean = 12.25, SD = 0.94) including 55 children with ADHD participated. While controlling for age, sex, sports participation, and body mass index, children were tested on the PACER 3 times during the school year. Procedures specified in the FITNESSGRAM test manual were explicitly followed. Hierarchical linear modeling was applied to analyze the data. Children with ADHD performed 8.6 fewer laps at intercept (baseline), than did healthy children without ADHD (t 878  = -6.20, P < .001). However, no significant differences emerged for time (slope). In addition, no significant interactions were found for ADHD with age, sex, sports participation, or body mass index. A diagnosis of ADHD, independent of selected predictor variables, explained lower PACER performance.

High Risk Children (HRC) are those with an increased risk of abnormal development due to any factor affecting neurological growth. Those factors have been the focus of most studies in this area. However, little is known about their long-term consequences over the course of child development. The goal was to study the cognitive, emotional and academic outcomes of 7-year-old children diagnosed as HRC at birth. We compared 14 HRC and 20 healthy children using the WISC-IV, BASC and Brunet-Lezine tests. HRC showed cognitive, emotional and academic deficits compared with healthy children. However, Brunet-Lezine scores obtained over the course of development (6, 12, 18 and 24 months) were not predictive of the children's' current psychological status. Long-term follow-up with HRC should be maintained until 7 years of age, at which point an appropriate treatment should be implemented.

Asymmetries in the distributions of birth dates in senior professional and youth soccer players have been interpreted as evidence for systematic discrimination against individuals born shortly before the cut-off date in assigning youth to specific age groups. This concept is known as the "relative age effect". The results of a longitudinal study of birth date distritubions of 2757 semi-professional and amateur senior soccer players in Belgium are presented. Records for competitive games were available in official statistics provided by the Royal Belgian Football Association. The chi-square statistic was used to examine differences between observed and expected birth date distributions. Regression analyses indicated a shift of bias when two different start dates were compared. Players born in the early part of the new age band (January to March) were over-represented compared with players born late in the new selection period (October to December). However, players with birthdays at the start of the old selection year (August) were still represented. In a retrospective analysis of 2138 players, variables indicative of match involvement, number of selections for matches, and time played were examined in relation to the relative age effect. The group of semi-professional and amateur senior soccer players born in the first quarter of the selected age band received more playing opportunities. Comparisons of birth date distributions (traditional approach to relative age effect) with match-related variables gave similar, though not entirely consistent, results. However, there were no differences for the mean number of selections and for playing minutes between players born at the start or the end of the selection year. Our findings suggest that match-based variables may provide a more reliable indication of the relative age effect in soccer.

Among HIV-1-infected patients, CD4+ T cell counts are well-established markers of cell-mediated immunity. Delayed-type hypersensitivity (DTH) skin tests can be used to evaluate in vivo cell-mediated immunity to common antigens. DTH responses to tuberculin purified protein derivative (PPD), sporotrichin, trichophytin, candidin and streptokinase/streptodornase antigens were assessed. Thirty-six HIV-1-infected children/adolescents and 56 age- and sex-matched HIV-1/HIV-2-seronegative participants were tested. All participants had a BCG scar. Fisher's exact test was used to evaluate significant differences between groups (p<0.05). The main characteristics of the HIV-1 patients were as follows: median age 8.1 years; 20/36 were males; 35 were vertical transmission cases; 34 were AIDS cases under antiretroviral therapy; median viral load = 3.04 log10 copies/ml; median CD4+ T cell count = 701 cells/μl. A total of 25% (9/36) and 87.5% (49/56) of HIV-1-infected and healthy participants, respectively, displayed DTH reactivity to at least one antigen (p<0.001). Among HIV-1-infected participants, reactivity to candidin predominated (8/36, 22.2%), while PPD positivity prevailed among healthy participants (40/56, 71.4%). PPD reactivity in the HIV-1-positive group was 8.3% (p<0.01). The median PPD induration was 2.5mm (range: 2-5mm) in the HIV-1 group and 6.0 mm among healthy participants (range: 3-15 mm). There was no correlation between PPD positivity and age. No correlation between CD4+ T cell counts and DTH reactivity was observed among HIV-1-infected patients. DTH skin test responses, including PPD reactivity, were significantly lower among HIV-1-infected participants compared to healthy controls, which likely reflects advanced disease and T cell depletion.

The purpose of the present study was to investigate the vascular flow density (VD) of macular superficial (SCP), deep capillary plexus (DCP), and choriocapillaris and the size of the foveal avascular zone (FAZ) area in healthy children using optical coherence tomography angiography (OCTA). The potential associations of age, sex, intraocular pressure, body mass index, spherical equivalent, and axial length with OCTA parameters were also investigated. A total of 75 eyes from 75 healthy children were included for analysis, with the mean age 11.51 ± 1.91 years (range, 8-16 years). At the level of the SCP, mean VD and mean FAZ area were, respectively, 54.29 ± 2.25% and 0.290 ± 0.109 mm 2 . At the level of the DCP and choriocapillaris, mean VD were 60.19 ± 1.76% and 66.58 ± 1.33%, respectively. After adjustment on the signal strength index, there was no significant correlation between age and all OCTA parameters. Intra-observer repeatability was 0.91, 0.82, and 0.88 in the SCP, DCP and choriocapillaris, respectively. In healthy eyes of children, only sex has a significant influence on the FAZ area. OCTA may provide a noninvasive and reliable approach for evaluating macular perfusion in children, although sex-related variations should be considered.

Since the ageing population demands a response to ensure older people remain healthy and active, we studied the dynamics of a recently proposed healthy ageing phenotype. We drew the phenotype's trajectories and tested whether their levels and rates of change are influenced by health behaviours, comorbidities and socioeconomic positions earlier in the life course. The English Longitudinal Ageing Study, a prospective, nationally representative sample of people aged ≥50 years, measured a set of eight biomarkers which make up the outcome of the healthy ageing phenotype three times over nearly a decade (N2004=5009, N2008=5301, N2013=4455). A cluster of health behaviours, comorbidities and socioeconomic positions were also measured repeatedly. We assessed the phenotype's distribution non-parametrically, then fitted linear mixed models to phenotypic change and further examined time interactions with gender and socioeconomic position. We ran additional analyses to test robustness. Women had a wider distribution of the healthy ageing phenotype than men had. The phenotype declined annually by -0.242 (95% confidence interval [CI]: -0.352, -0.131). However, there was considerable heterogeneity in the levels and rates of phenotypic change. Women started at higher levels, then declined more steeply by -0.293 (CI: -0.403, -0.183) annually, leading to crossover in the trajectories. Smoking and physical activity assessed on the Allied Dunbar scale were strongly associated with the trajectories. Though marked by secular decline, the trajectories of the healthy ageing phenotype showed distinct socioeconomic gradients. The trajectories were also susceptible to variations in health behaviours, strengthening the case for serial interventions to attain healthy and active ageing. Copyright © 2016 The Author.

Background The 13-valent pneumococcal conjugate vaccine (PCV13) was licensed based on the results of immunogenicity studies and correlates of protection derived from randomized clinical trials of the 7-valent conjugate pneumococcal vaccine. We assessed the vaccination effectiveness (VE) of the PCV13 in preventing invasive pneumococcal disease (IPD) in children aged 7–59 months in a population with suboptimal vaccination coverage of 55%. Methods The study was carried out in children with IPD admitted to three hospitals in Barcelona (Spain) and controls matched by hospital, age, sex, date of hospitalization and underlying disease. Information on the vaccination status was obtained from written medical records. Conditional logistic regression was made to estimate the adjusted VE and 95% confidence intervals (CI). Results 169 cases and 645 controls were included. The overall VE of ≥1 doses of PCV13 in preventing IPD due to vaccine serotypes was 75.8% (95% CI, 54.1–87.2) and 90% (95% CI, 63.9–97.2) when ≥2 doses before 12 months, two doses on or after 12 months or one dose on or after 24 months, were administered. The VE of ≥1 doses was 89% (95% CI, 42.7–97.9) against serotype 1 and 86.0% (95% CI, 51.2–99.7) against serotype 19A. Serotype 3 showed a non-statistically significant effectiveness (25.9%; 95% CI, -65.3 to 66.8). Conclusions The effectiveness of ≥1 doses of PCV13 in preventing IPD caused by all PCV13 serotypes in children aged 7–59 months was good and, except for serotype 3, the effectiveness of ≥1 doses against the most frequent PCV13 serotypes causing IPD was high when considered individually.

To identify potentially modifiable late-life biological, lifestyle, and sociodemographic factors associated with overall and healthy survival to age 85. Prospective longitudinal cohort study with 21 years of follow-up (1991-2012). Hawaii Lifespan Study. American men of Japanese ancestry (mean age 75.7, range 71-82) without baseline major clinical morbidity and functional impairments (N = 1,292). Overall survival and healthy survival (free from six major chronic diseases and without physical or cognitive impairment) to age 85. Factors were measured at late-life baseline examinations (1991-1993). Of 1,292 participants, 1,000 (77%) survived to 85 (34% healthy) and 309 (24%) to 95 (<1% healthy). Late-life factors associated with survival and healthy survival included biological (body mass index, ankle-brachial index, cognitive score, blood pressure, inflammatory markers), lifestyle (smoking, alcohol use, physical activity), and sociodemographic factors (education, marital status). Cumulative late-life baseline risk factor models demonstrated that age-standardized (at 70) probability of survival to 95 ranged from 27% (no factors) to 7% (≥ 5 factors); probability of survival to 100 ranged from 4% (no factors) to 0.1% (≥ 5 factors). Age-standardized (at 70) probability of healthy survival to 90 ranged from 4% (no factors) to 0.01% (≥ 5 factors). There were nine healthy survivors at 95 and one healthy survivor at 100. Several potentially modifiable risk factors in men in late life (mean age 75.7) were associated with markedly greater probability of subsequent healthy survival and longevity. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

Promotion of healthy lifestyles in children focuses predominantly on proper nutrition and physical activity, elements now widely recognised as essential for a healthy life. Systematic reviews have shown that nature-related activities also enhance general well-being as reflected in increased physical activity, a healthier diet, reduced stress and better sleep. Recent research suggests that many young children in Hong Kong between the ages of two and four in Hong Kong are more sedentary than recommended and seldom participate in active play, placing them at risk of becoming overweight or obese. The proposed project aims to investigate whether connecting families to nature positively influences physical activity (i.e., active playtime) and healthy eating routines in children aged 2 to 4. We recently conducted a pilot study in Hong Kong to develop a programme, Play & Grow, based on the most successful evidence-based international preschool interventions. In addition to adopting the healthy eating and physical activity elements of these interventions, this project will additionally include a third novel element of Connectedness to nature: discovering nature through games and awareness of sounds, touch, smells, and temperature. To test the effectiveness of this modified intervention, a randomised controlled trial (RCT) involving 240 families with children aged 2 to 4 will be conducted. Families and children will take part in weekly one-hour activity sessions for 10-weeks. Lifestyle-related habits will be assessed before and immediately after the 10-week intervention, with follow up testing at 6 and 12 months' post intervention. A novel measuring tool created specifically for assessing Connectedness to nature, Nature Relatedness Scale (NRS), will be validated and tested for reliability prior to the RCT. The results of the RCT are intended to be used to understand which components of the intervention are most effective. The objectives of this project will be achieved
