Metabolic parameters and adipokine profile during GH replacement therapy in children with GH deficiency
2007
Objective: GH replacement therapy in children with GH deficiency (GHD) mainly promotes linear growth. Not only have very few studies fully analyzed the metabolic consequences of GH therapy, but also the question as to whether GH may affect adipokine secretion has been insufficiently investigated. Our aim was to study the effects of GH replacement therapy on auxological data, lipid and glycemic profiles, insulin homeostasis (HOMA-IR) and serum adipokines in children. Methods: This was a 1-year prospective study. Thirty-four GHD children (11.6 ± 2.6 years) and thirty healthy matched controls were enrolled. Children affected by GHD were studied both before beginning continuous GH replacement t…
Prenatal ambient air pollution exposure, infant growth and placental mitochondrial DNA content in the INMA birth cohort
2017
Background: The association between prenatal air pollution exposure and postnatal growth has hardly been explored. Mitochondrial DNA (mtDNA), as a marker of oxidative stress, and growth at birth can play an intermediate role in this association. Objective: In a subset of the Spanish birth cohort INMA we assessed first whether prenatal nitrogen dioxide (NO2) exposure is associated with infant growth. Secondly, we evaluated whether growth at birth (length and weight) could play a mediating role in this association. Finally, the mediation role of placental mitochondrial DNA content in this association was assessed. Methods: In 336 INMA children, relative placental mtDNA content was measured. L…
Calcium Intake and Nutritional Adequacy in Spanish Children: The ANIVA Study
2017
Calcium is an important nutrient for child development. The main objective of this study was to assess calcium intake and its adequacy with dietary reference intake (DRI) in Spanish children. The ANIVA (Antropometría y Nutrición Infantil de Valencia) study is a descriptive cross-sectional study. During two academic years 2013–2014 and 2014–2015, 1176 schoolchildren aged 6–9 years were selected from 14 primary schools in Valencia (Spain). Three-day food records were used to assess dietary intake, completed by parents/guardian. Anthropometric data (weight and height) were evaluated in all subjects. Nutritional intake was compared to estimated average requirements (EARs) and adequate intake (A…
Fundamental movement skills in adolescents : secular trends from 2003 to 2010 and associations with physical activity and BMI
2018
The aim of this study was to examine the secular trends in fundamental movement skills (FMS) among 15- to 16-year-old adolescents at 2 assessment points scheduled in 2003 and 2010 and to investigate the associations between FMS, physical activity (PA), and body mass index (BMI). In 2003, self-reported PA, weight and height, and objective FMS scores were collected from 2390 students, and in 2010, similar data were generated from a second sample of 1346 students. FMS were assessed during both assessment phases using 3 identical objective FMS tests that were figure 8 dribbling, jumping laterally, and coordination track tests. This study indicated that the sum index of FMS did not change among …
Resting energy expenditure and body composition in morbidly obese, obese and control subjects
1994
Resting energy expenditure (REE) was investigated by indirect calorimetry in relation to body composition and to different degrees of obesity in order to assess if a defective energy expenditure contributes to extra body fat accumulation. Differences were found between control subjects (group C; BMI 23 +/- 0.5 kg/m2, REE 5890 +/- 218 kJ/day; mean +/- SEM) and obese subjects (group O; BMI 34.2 +/- 0.9 kg/m2, REE 7447 +/- 360 kJ/day; P0.0001) and between group C and morbidly obese subjects (group MO; BMI 49.9 +/- 1.6 kg/m2, REE 8330 +/- 360 kJ/day; P0.0001); REE was not significantly different between groups O and MO. Body composition data were obtained by means of body impedance analysis. Ev…
Vertical jumping height and horizontal overhead throwing velocity in young male athletes
1992
The purpose of this study was to examine the effects of calendar and skeletal age, anthropometric dimensions, training history and their interactions on vertical jumping height and horizontal overhead throwing velocity in a cross-section of 318 young male athletes (age range 9-16 years) participating in cross-country skiing (n = 70), basketball (n = 40), apparatus gymnastics (n = 19), ice hockey (n = 50), track and field (n = 89) and wrestling (n = 50). Vertical jumping height was measured with four different loads held on the shoulders and then interpolated for loads representing 0 and 40% body mass. Horizontal overhead throwing velocity using both hands was determined for seven balls of d…
Associations of age, body size, and maturation with physical activity intensity in different laboratory tasks in children.
2021
We investigated the associations of age, sex, body size, body composition, and maturity with measures of physical activity (PA) intensity in children. PA intensity was assessed using VO2 as % of VO...
Functional Inactivation of the Genome-Wide Association Study Obesity Gene Neuronal Growth Regulator 1 in Mice Causes a Body Mass Phenotype
2012
To date, genome-wide association studies (GWAS) have identified at least 32 novel loci for obesity and body mass-related traits. However, the causal genetic variant and molecular mechanisms of specific susceptibility genes in relation to obesity are yet to be fully confirmed and characterised. Here, we examined whether the candidate gene NEGR1 encoding the neuronal growth regulator 1, also termed neurotractin or Kilon, accounts for the obesity association. To characterise the function of NEGR1 for body weight control in vivo, we generated two novel mutant mouse lines, including a constitutive NEGR1-deficient mouse line as well as an ENU-mutagenised line carrying a loss-of-function mutation …
Does school physical education really contribute to accelerometer-measured daily physical activity and non sedentary behaviour in high school student…
2018
Physical education has been highlighted as an important environment for physical activity promotion, however, to our knowledge there are no previous studies examining the contribution of physical education to daily accelerometer-measured physical activity and non sedentary behaviour. The purpose was to compare the accelerometer-measured physical activity and sedentary behaviour between physical education, non-physical education and weekend days in adolescents. Of the 394 students from a Spanish high school that were invited to participate, 158 students (83 boys and 75 girls) aged 13-16 years were analyzed (wear time ≥ 600 min). Participants' physical activity and sedentary behaviour were ob…
Differences in Weight Status and Energy-Balance Related Behaviors among Schoolchildren across Europe: The ENERGY-Project
2012
Published version of an article published in the journal: PLoS ONE. Also available from the publisher at: http://dx.doi.org/10.1371/journal.pone.0034742 Background: Current data on the prevalence of overweight and energy-balance behaviors among European children is necessary to inform overweight prevention interventions. Methodology/Principal Findings: A school-based survey among 10–12 year old children was conducted in seven European countries using a standardized protocol. Weight, height, and waist circumference were measured; Engagement in physical activity, sedentary and dietary behaviors, and sleep duration were self-reported. Descriptive analyses were conducted, looking at differences…
