In large transdisciplinary research teams finding the balance between using the most appropriate and needed measures for data collection and minimising participant burden is often a significant challenge. This paper aims to describe the development process for selecting a set of determinants of physical activity behaviours in 9-12 years old children. An internal small group ( = 8) worked iteratively with an external large group of experts and stakeholders ( = 30-50) in three steps: 1) External input - Identification through expert opinion; 2) Internal input - Identification and selection via a systematized approach; 3) External validation of the selected measures.

Objective: This study aimed to explore the utility of a high-intensity interval training (HIIT) app as a remote exercise support strategy in children with obesity through assessing adherence, possible effects on obesity-related outcomes, and perceptions of its use to support counseling and improve the treatment of children with obesity.

Methods: Thirty-seven children (94.6% with obesity; 45.

Article Synopsis
  • The 24-hour Movement Questionnaire (QMov24h) was developed to effectively measure sleep, sedentary behaviour, and physical activity, aiming to comply with WHO guidelines.
  • The development process involved input from end-users and experts, as well as comparisons to existing measures for validation, resulting in a significant testing sample of 117 participants.
  • Results indicated that the QMov24h has strong validity for measuring various movement behaviours and shows considerable reliability, making it a suitable tool for evaluating compliance with physical activity guidelines in adults.

Purpose: The present study aimed to explore the influence of diet and physical activity (PA) changes on bone mineral content (BMC) and density (BMD) alterations in adolescents with obesity undergoing a weight loss program.

Methods: Six-month longitudinal data from 71 adolescents (aged 15.1 [± 1.

With Europe's ageing population and rising demand for palliative care, it is crucial to examine the use of palliative care among older adults during their last years of life and understand the factors influencing their access and end-of-life circumstances. This study employed a cohort of SHARE participants aged 65 years or older who had passed away between Wave 6 (2015) and Wave 7 (2017). Information on death circumstances, palliative care utilization, and associated variables were analysed.

Background: Recognizing the need for palliative care (PC) and referral to PC teams improves patients' quality of life. However, in patients with moderate/severe clinical complexity, early recognition of the need for PC may not correspond to referral to specialized PC services. The definition for clinical complexity is still underexplored, as well as the instruments available to assess complexity.

Carotid intima-media thickness (cIMT) is a subclinical marker of atherosclerotic development, which is impaired in adolescents with obesity. This study aimed to analyze the impact of physical activity (PA), cardiorespiratory fitness (CRF), body mass index (BMI), and body composition changes on the cIMT of adolescents with obesity. Longitudinal data (6 months) from adolescents aged 12-18 years, with a BMI ≥97th percentile, previously recruited for the non-randomized controlled trial PAC-MAnO (Clinicaltrials.

Individual variability may contribute to the modest and inconsistent results reported in obesity-management interventions. This study aimed to investigate the impact of non-modifiable as well as modifiable factors on body mass index (BMI) and body fat variance in adolescents with obesity followed in a clinical obesity-management programme, in order to better understand individual variability. Non-modifiable factors (i.

Effective and safe exercise protocols for obesity management in adolescents are imperative. This study aimed to analyse compliance, efficacy, and safety of combined high-intensity interval training circuit (HIIT) in the management of obesity (including overweight) in adolescents, compared to traditional training (TT). Data from 55 adolescents (47.

The value of physical activity (PA) counselling and its impact on PA behaviour and weight management have been in question. The main aim of this study was to analyse 6 and 12-month effects of a PA consultation (PAC-a structured form of PA counselling) with and without the inclusion of structured exercise, on body mass index (BMI) z-score, body composition and PA levels of adolescents with excess weight (BMI ≥p85), as part of a clinical multicomponent weight management program. Participants were allocated at baseline into a control (CG-standard care, including paediatric and nutrition consultations) and two experimental groups (EGI and EGII).

Purpose: In adolescents, the definition and clinical implications of metabolically healthy overweight (MHO) status have not been established. This study aimed to investigate the prevalence of MHO according to its most widespread definition, which is based on metabolic syndrome (MS), and to explore further metabolic indicators such as Homeostatic Model Assessment of Insulin Resistance, total cholesterol, low-density lipoprotein cholesterol, alanine aminotransferase, and C-reactive protein levels, together with metabolic health predictors in a sample of adolescents attending a pediatric obesity clinic.

Methods: Data from 487 adolescents categorized as overweight (52.

Background: Investigating life-stage factors associated with overweight may be useful in the prevention of excessive BMI increase. The main aim of this study was to investigate the influence of the route of delivery, birth weight and overweight onset on overweight severity in a sample of overweight adolescents followed at a Pediatric Obesity Clinic.

Methods: Clinical data from 412 adolescents with overweight (BMI ≥ p85), aged 10-18 were retrospectively collected and analyzed.

Purpose: Acanthosis nigricans (AN) is a hyperpigmented dermatosis associated with obesity and insulin resistance (IR). There is no consensus whether AN extension scoring offers added value to the clinical estimation of IR. In this study we aimed to assess and score AN using both a short and an extended version of the scale proposed by Burke et al.

Background: Adolescent overweight is a major public health concern, as it is associated with several short-run and long-run adverse health outcomes. Inappropriate health behaviours may be at the front of this epidemic. There is widespread need for new strategies that may positively influence dietary and physical activity behaviours.

Unlabelled: Physical activity (PA) is recognized as having many health benefits. Despite of all the efforts, the majority of the overweight adolescents still present low levels of PA. PA consultation can be a cost-effective way of enhancing PA and improve weight status among overweight adolescents.
