Testing a family system-based intervention (ENTREN-F Programme) for a paediatric obesity sample by a randomized controlled trial.

This study evaluated the effectiveness of 'ENTREN-F' -a multi-component, family system-based intervention-for managing paediatric obesity at National Health Primary Care. A 3-arm, parallel-design, single-blinded randomized controlled trial (RCT), 165 families were randomized: Arm 1) ENTREN-F(n = 62) is a 12-week cognitive-behavioural intervention (CBT) family system-based programme, addressing lifestyle changes, children's emotional and social development and the family system, Arm 2) 'ENTREN' (n = 52) is a CBT family-based programme for children and parents, not addressing the family system, and Arm 3) Control group (CG) (n = 51) covers individual behavioural monitoring. All children were clinical interviewed to assess a diagnosis.

Beyond femininity or masculinity: gender typologies and healthy eating in early adulthood.

Purpose: In the field of health sciences gender is often confused with biological sex (male/female) or reduced to a dichotomous classification (masculinity/femininity). The concepts of sex and gender interact with each other, but they are not equivalent. According to Sandra Bem four gender typologies can be established (androgynous, masculine, feminine and undifferentiated).

European fitness landscape for children and adolescents: updated reference values, fitness maps and country rankings based on nearly 8 million test results from 34 countries gathered by the FitBack network.

Objectives: (1) To develop reference values for health-related fitness in European children and adolescents aged 6-18 years that are the foundation for the web-based, open-access and multilanguage fitness platform (FitBack); (2) to provide comparisons across European countries.

Methods: This study builds on a previous large fitness reference study in European youth by (1) widening the age demographic, (2) identifying the most recent and representative country-level data and (3) including national data from existing fitness surveillance and monitoring systems. We used the Assessing Levels of PHysical Activity and fitness at population level (ALPHA) test battery as it comprises tests with the highest test-retest reliability, criterion/construct validity and health-related predictive validity: the 20 m shuttle run (cardiorespiratory fitness); handgrip strength and standing long jump (muscular strength); and body height, body mass, body mass index and waist circumference (anthropometry).

Fitness, body composition, and metabolic risk scores in children and adolescents: the UP&DOWN study.

We aimed to analyse the longitudinal association between physical fitness (PF) and body composition (BC) with a metabolic risk score (Met4) in children and adolescents and to elucidate whether the association between PF and Met4 differs when using relativized or absolute fitness variables. A total of 188 children (86 females) and 195 adolescents (97 females) were included. Cardiorespiratory fitness (CRF) was determined by the 20-m shuttle run test, and muscular fitness (MF) was determined by hand grip and standing long jump tests.

Comparison of Adherence to Mediterranean Diet between Spanish and German School-Children and Influence of Gender, Overweight, and Physical Activity.

Background: Poor dietary habits and low levels of physical activity (PA) have a strong tendency to track from childhood into adulthood. The Mediterranean Diet (MD) is known to be extremely healthy, associated with lower BMI and a lower risk of obesity in children and adolescents. Therefore, adherence to the MD was compared between Spanish ( = 182) and German ( = 152) children aged 10 to 13 years to examine a possible more "westernized" diet in Spain with a non-Mediterranean country, that traditionally prefers a "Western diet" and to determine the association between adherence to the MD and gender, body composition, and PA levels.

ENTREN-F family-system based intervention for managing childhood obesity: Study protocol for a randomized controlled trial at primary care.

Background: Pediatric obesity is a primary public health concern, and designing effective programs for managing it is of the utmost importance. The objective of this study was to describe the protocol study of a three-arm, parallel, randomized controlled trial aimed at assessing the efficacy of a family-system-based intervention ("ENTREN-F" program) for managing childhood obesity, compared to the "ENTREN" program (no "F" - without specific family-system-based workshop) and a control group (behavioral monitoring).

Methods/design: The ENTREN-F program was a multicomponent family-system-based intervention carried out by a multidisciplinary team in the primary health care setting.

Family-reported barriers and predictors of short-term attendance in a multidisciplinary intervention for managing childhood obesity: A psycho-family-system based randomised controlled trial (ENTREN-F).

Objective: This study was aimed to examine patient enrolment in the pre-intervention stage, family-reported barriers, attendance rates and underlying predictors of short-term attendance in a family-system-based randomised controlled trial for managing childhood obesity in children aged 8-12-years-old (ENTREN-F).

Method: Psychosocial and anthropometric measures were collected through primary health referral. The data were used for descriptive analyses of sample characteristics and linear regression analyses.

Objectively measured physical activity and academic performance in school-aged youth: The UP&DOWN longitudinal study.

Prospective Associations of Physical Activity and Health-Related Physical Fitness in Adolescents with Down Syndrome: The UP&DOWN Longitudinal Study.

(1) Background: Numerous studies have focused on examining the association between PA levels and health-related physical fitness components in children or adolescents without disabilities. However, research on the association between PA and health-related physical fitness in adolescents with DS (Down syndrome) is limited, and most of the previous studies have been developed with a cross-sectional perspective. Therefore, the aim of the present study was to assess the prospective association of accelerometer-based PA at baseline with health-related physical fitness at a 2-year follow-up in a relatively large sample of adolescents with DS from the UP&DOWN study.

Fitness, waist circumference and their association with future blood pressure in youth: The UP&DOWN Longitudinal Study.

Objectives: The aim was to determine the independent associations of muscular fitness (MF), cardiorespiratory fitness (CRF) and waist circumference (WC) with blood pressure (BP) levels over 2 years in children and adolescents.

Methods: 1089 children (517 females) and 787 adolescents (378 females) with complete data on fitness, WC and BP (systolic [SBP] and diastolic [DBP]) were included. Upper MF was assessed through the handgrip strength test, and lower MF using the standing long jump test.

A longitudinal gender perspective of well-being and health in spanish youth: the UP&DOWN study.

Previous studies have observed a link between gender and well-being and health in young populations. The purpose of this research was twofold: (1) to analyse the cross-sectional relationship between gender status with well-being indicators and self-perceived health in adolescents at baseline and at 2-year follow-up and (2) to evaluate the prospective associations between gender at baseline and well-being indicators/self-perceived health assessed at 2-year follow-up. Well-being was measured using the KIDSCREEN-10 questionnaire (as a measure of health-related quality of life (HR-QoL)), the Children's Hope Scale and the Positive and Negative Affect Schedule.

Correlates of dual trajectories of physical activity and sedentary time in youth: The UP & DOWN longitudinal study.

Trajectories of physical activity and sedentary time (SED) may differ between subgroups of youth. The aim of this study was to identify group-based dual trajectories of physical activity and SED and explore individual, social, and environmental correlates of these trajectories. Longitudinal data (three time points, baseline 2011-2012) of Spanish youth (n = 1597, mean age = 11.

Longitudinal associations of physical fitness and body mass index with academic performance.

No studies have analyzed the longitudinal associations of change in physical fitness components and obesity with academic performance. The aim of the study was to examine longitudinal associations of changes in physical fitness components and body mass index with academic performance among youth, and whether the physical fitness components are moderators of the longitudinal association between obesity and academic performance in youth. Longitudinal analyses (2 years) included 1802 youths.
