Impact of a participatory research intervention based on a citizen science approach on snacking consumption in European adolescents from deprived areas: A cluster randomised control trial of the Seeds…
Improving adolescent diets requires promising interventions, best developed through participatory research like Citizen Science (CS). The present study aimed to assess the impact of a CS intervention on the consumption of healthy and unhealthy snacking choices for adolescents living in deprived areas and the influence of gender, age, and socioeconomic status (SES) in snacking behaviour. SEEDS is a cluster-randomised controlled trial (c-RCT) in fo…

A Policy‐Driven Scoping Review of the Regulatory and Operational Framework Addressing Obesity in Children in Need in Greece
Multisystem collaboration and actions are needed to tackle childhood obesity, especially in the most vulnerable. This review aimed to describe the regulatory and operational framework associated with four delivery systems (social protection, food, education and health) for obesity prevention in children in need in Greece, and to synthesise related evidence of effectiveness, implementation, barriers and facilitators. The Joanna Briggs Institute (J…
Association between Screen Time and Sociodemographic Factors, Physical Activity, and BMI among Children in Six European Countries (Feel4Diabetes): A Cross-Sectional Study
Screen time among children in most European countries is notably high and is influenced by various sociodemographic and other factors. Our study aimed to explore the associations between parents' sociodemographic characteristics, socioeconomic status, body mass index (BMI), physical activity, risk status for type 2 diabetes, and their children's BMI, physical activity, and screen time. The data were sourced from the 2016 Feel4Diabetes study, invo…
Infant BMI trajectories as early risk markers of poor psychosocial health in preadolescence
Infants with BMI growth in the high reference ranges had poorer psychosocial outcomes in preadolescence. Whilst further research is needed to replicate these findings, monitoring early infant growth trajectories may allow for early stratification of infants at risk of poor psychosocial outcomes
Longitudinal changes in preschoolers’ adiposity indicators according to compliance with 24-hour movement behavior guidelines: Results from the ToyBox-study
The change in BMI z-scores after one year is less optimal for preschoolers who do not comply with the 24-hour movement behavior guidelines compared to preschoolers who comply with the integrated guidelines, although not clinically relevant. Future studies should incorporate longer follow-up periods to observe the effects of compliance to the integrated guidelines on adiposity indicators in preschool children

Cross-sectional data from the Feel4Diabetes study for 24,562 adults residing in low socioeconomic areas wer…
Earlier Age at Menarche Is Associated with Body Fat and Negative Body Image in Adult Life
Earlier age at menarche is one of the well-documented antecedents of a range of adverse health effects in adulthood including obesity and psychopathological effects. Yet, few researchers have examined the potential association of menarcheal age with body fat distribution, self-perception, and body image. We retrospectively tested a sample (N = 392) of adult women (18-80 years) to examine the associations of age at menarche with body composition a…

Nurturing children's development through healthy eating and active living: Time for policies to support effective interventions in the context of responsive emotional support and early learning
Fostering the growth, development, health, and wellbeing of children is a global priority. The early childhood period presents a critical window to influence lifelong trajectories, however urgent multisectoral action is needed to ensure that families are adequately supported to nurture their children's growth and development. With a shared vision to give every child the best start in life, thus helping them reach their full developmental potentia…
The Influence of Parental Dietary Behaviors and Practices on Children’s Eating Habits
Poor dietary habits established during childhood might persist into adulthood, increasing the risk of developing obesity and obesity-related complications such as Type 2 Diabetes Mellitus. It has been found that early modifications in eating habits, especially during childhood, might promote health and decrease the risk of developing diseases during later life. Various studies found a great influence of parental dietary habits on dietary behavior…

Regional, demographic and national influences on attitudes and beliefs with regard to physical activity, body weight and health in a nationally representative sample in the European Union
Introduction Although the benefits of physical activity regarding body-weight gain and health in general are now widely accepted, physical activity levels remain low among citizens in the western world. This could be attributed to certain attitudes and beliefs about physical activity. Identifying and understanding these parameters would be the first step in an attempt to increase the levels of physical activity in populations generally characteri…
