Anthropometric survey on children with Down syndrome

2017

Abstract Objective Study of anthropometric values in the medical records of a representative group of paediatric patients with Down syndrome, from the Down syndrome Unit of the Paediatric Department of Valencia's Hospital Clinico Universitario, from 2000 to 2014. Patients and methods Descriptive observational study in a group of 140 patients between 1 and 13 years. The group was configured based on the inclusion and exclusion criteria. We extracted data about birth from their first visit, and subsequently patient data at the time of each visit (643 measurements). Results 103 patients with regular trisomy of Down syndrome were recorded and studied. There were 59 (57%) boys and 44 (43%) girls…

Anthropometric measures of Spanish children with autism spectrum disorder

2015

Abstract We aimed to compare body mass index (BMI) and healthy eating index (HEI) in children with autism spectrum disorder (ASD, n  = 105) and typically developing (TD, n  = 495) children. They were aged 6–9 years, lived in Valencia (Spain) and came from similar cultural and socio-economic backgrounds. In this case–control study, the weight, height and BMI were measured for both groups. Three-day food records were used to assess dietary intake. Although the differences between children with ASD and TD children in raw BMI ( p  = 0.44), BMI z -score ( p  = 0.37), HEI ( p  = 0.43) and total energy intake ( p  = 0.86) were not significant, children with ASD and the boys subgroup were shorter (…

Transient suppression of atopy in early childhood is associated with high vaccination coverage.

2003

Objective. To analyze prevalences of allergic sensitization and atopic disease in relation to vaccination coverage. Methods. A German atopy risk-enhanced birth cohort of 1314 neonates who were born in 1990 in 5 German cities was studied. A total of 943 children participated in the follow-up visit at 5 years of age. Atopic symptoms and diagnoses (derived from structured interviews), total serum immunoglobulin E, and specific immunoglobulin E against 9 common allergens (CAP Radio-Allergo-Sorbent Test Fluoro-Enzyme Immunoassay) were evaluated. Children were grouped into dose percentiles according to cumulative doses of any vaccine given up to 5 years of age (<10%, 0–11 doses; 10%–50%, 1…

The aim of the present study was to extend the previous intervention research in math by examining whether elementary school children with poor calculation fluency benefit from strategy training focusing on derived fact strategies and following an integrative framework, i.e., integrating factual, conceptual, and procedural arithmetic knowledge. It was also examined what kind of changes can be found in frequency of using different strategies. A quasi-experimental design was applied, and the study was carried out within the context of the school and its schedules and resources. Twenty schools in Finland volunteered to participate, and 1376 children were screened in for calculation fluency pro…

Maternal body mass index, change in weight status from childhood to late adulthood and physical activity in older age

2021

This study aimed to examine the longitudinal associations of maternal body mass index (BMI), weight status in childhood and late adulthood and device-measured total physical activity (TPA) in older age. The study involves 552 participants from Helsinki Birth Cohort Study who were born in Helsinki, Finland, in 1934-1944. TPA was measured with a multisensory body monitor at a mean age of 70 years and expressed in metabolic equivalent of task hours/day (METh/d). Childhood overweight (BMI > 85th percentile) was based on school health records at 6-7 years of age, and late adulthood overweight (BMI >= 25 kg/m(2)) was based on clinical measurements at the mean age of 61 years. Childhood overweight…

Facetten der Körperbildstörung: eine differenzielle Analyse des TEK-KJ (Test zur Erfassung der Körperbildstörung bei Kindern und Jugendlichen) zur di…

2018

Zusammenfassung. Zur Erfassung der haptisch-perzeptiven Komponente der Körperbildstörung – einem Kernkriterium der Essstörungen Anorexia nervosa und Bulimia nervosa – stehen nur sehr wenige gut evaluierte Verfahren zur Verfügung. In der vorliegenden Arbeit werden differenzielle Analysen zum Test zur Erfassung der Körperbildstörung bei Kindern und Jugendlichen (TEK-KJ) anhand einer großen Kinder- und Jugendlichenstichprobe dargestellt und zum ersten Mal Daten für männliche Kinder und Jugendliche ausgewertet. Dies beinhaltet die Prüfung der konvergenten Validität im Vergleich zur Contour Drawing Rating Scale (CDRS) und die Analyse von Unterschieden zwischen Kindern und Jugendlichen verschied…

A statistical study of the quality of surface water intended for human consumption near Valencia (Spain)

2007

Water quality in the European Union is subject to legislation through directives that are applicable in all Member States. The directives specify a set of physical and chemical parameters that should be regularly controlled using a network of sampling points, with sampling based on the intended use of the water. This paper presents the results of a statistical comparison of the quality of water intended for human consumption at two different locations (the Canal de Benagéber and the Canal Júcar-Turia) near the town of Valencia (Spain). These are currently the only canals that could supply Valencia and other nearby towns with drinking water. The parameters considered in this paper are the on…

Exposure and Risk Assessment of Hg, Cd, As, Tl, Se, and Mo in Women of Reproductive Age Using Urinary Biomonitoring

2021

The present study analyzed the exposure and risk assessment of 4 toxic (Hg, Cd, As, Tl) and 2 essential (Se, Mo) elements in 119 Spanish women of reproductive age. The focus was on the elements for which risk-based benchmark, biomonitoring equivalents, or health-related human biomonitoring values have already been established. All elements presented frequencies of detection of 100% (greater than the limit of detection), except for Cd (99%). The 95th percentile concentrations were, for the toxic metals, 358.37 µg/L (total As), 1.10 µg/L (Cd), 0.41 µg/L (Tl), and 3.03 µg/L (total Hg) and, for the essential elements, 68.95 µg/L (total Se) and 154.67 (Mo). We examined sociodemographic factors a…

549 Prevention of Obesity Through Healthy Nutrition in the First Year of Life

2012

Background Obesity, defined as excess body fat can be diagnosed at 6 months. In children, BMI percentiles are used, defining the overweight between 85–95 and obesity >95. The main predictors of primary obesity in infancy are high birthweight, parental obesity, low total energy expenditure and energy intake (EI). Aim Calculation of optimal EI in infants. Method Calculation of estimated energy requirements (EER) for infants was made according to the formulas: [(89×Gkg)-100]+175 between 0–3 months, [(89×Gkg)-100]+56, between 4–6 months, [(89×Gkg)-100]+22, between 7–12 months. Calculation of fluid requirements was made according to Apert formula: G g /10+200(300). Results Were studied 11 infant…
