Predicting VOmax in Children and Adolescents Aged between 6 and 17 Using Physiological Characteristics and Participation in Sport Activities: A Cross-Sectional Study Comparing Different Regression Models Stratified by Gender.

Background: The aim of this study is to use different regression models to capture the association between cardiorespiratory fitness VO2max (measured in mL/kg/min) and somatometric characteristics and sports activities and making better predictions. Methods: multiple linear regression (MLR), quantile regression (QR), ridge regression (RR), support vector regression (SVR) with three different kernels, artificial neural networks (ANNs), and boosted regression trees (RTs) were compared to explain and predict VO2max and to choose the best performance model. The sample consisted of 4908 children (2314 males and 2594 females) aged between 6 and 17.

Anthropometric, Lifestyle Characteristics, Adherence to the Mediterranean Diet, and COVID-19 Have a High Impact on the Greek Adolescents' Health-Related Quality of Life.

Objective: The study aimed at analyzing the relationship between anthropometric characteristics, lifestyle, and dietary habits, as well as the burden of the pandemic on the health-related quality of life among Greek pupils.

Research Methods And Procedures: On the whole, 2088 adolescents aged 12-18 years from Attica, Greece, were enlisted in this school-based cross-sectional study that took place in May-December 2021. Health-related quality of life was estimated through the KIDSCREEN-27 questionnaire, adherence to the Mediterranean diet-through the KIDMED test.

Effects of Nutrition, and Physical Activity Habits and Perceptions on Body Mass Index (BMI) in Children Aged 12-15 Years: A Cross-Sectional Study Comparing Boys and Girls.

: The aim of the present study was to examine the effects of socioeconomic status, nutrition and physical activity lifestyle habits and perceptions on Body Mass Index (BMI) in children aged 12-15 years in Greece. Furthermore, to compare the difference between the two sexes. This is a cross-sectional study conducted on a representative secondary school cohort that included 5144 subjects, aged 12 to 15 years.

Worldwide actions against plastic pollution from microbeads and microplastics in cosmetics focusing on European policies. Has the issue been handled effectively?

Microbeads are solid primary microplastics < 5 mm in diameter that are added to cosmetic products for cleansing and/or exfoliation of the skin. After use, they are discharged into the drain and end up in Wastewater Treatment Plants (WWTPs), from which they can escape into waters. Once disposed, there is no efficient method of recovery and the environmental conditions do not allow full biodegradation.

Effects of Body Mass Index (BMI), demographic and socioeconomic factors on organized physical activity (OPA) participation in children aged 6-15 years: a cross-sectional study comparing primary and secondary school children in Greece.

Background: The aim of the present study was to examine the influence of body mass index category, as well as of demographic and socioeconomic factors on the participation in organized physical activity (OPA) of schoolchildren attending primary and secondary school in Greece. Furthermore, to compare the difference between the two levels.

Methods: This is a cross-sectional study conducted on a representative elementary and secondary school cohort, derived using stratification and probability proportional to size (PPS) methodology.

Utility and applicability of the "Childhood Obesity Risk Evaluation" (CORE)-index in predicting obesity in childhood and adolescence in Greece from early life: the "National Action Plan for Public Health".

Unlabelled: Early identification of infants being at high risk to become obese at their later childhood or adolescence can be of vital importance in any obesity prevention initiative. The aim of the present study was to examine the utility and applicability of the "Childhood Obesity Risk Evaluation (CORE)" index as a screening tool for the early prediction of obesity in childhood and adolescence. Anthropometric, socio-demographic data were collected cross-sectionally and retrospectively from a representative sample of 5946 children, and adolescents and were combined for calculating the CORE-index score.

Sex differences in depression among older adults: are older women more vulnerable than men in social risk factors? The case of open care centers for older people in Greece.

This study examined depression, which, research has indicated, is the most common mental health problem affecting older people, especially women. Our objective was to estimate the prevalence of depression among older people in an urban Greek population and to investigate the covariates of depression symptoms prevalence by gender. The sample consisted of 360 individuals, 218 women and 142 men, aged 60 years or older, members of four open care centers for older people in Greece.

Comparing oil based ointment versus standard practice for the treatment of moderate burns in Greece: a trial based cost effectiveness evaluation.

Background: The local treatment of burn wounds has long been a subject of debate. The objective of this study was to compare the cost and the effectiveness of Moist Exposed Burn Ointment -MEBO versus a combination of povidone iodine plus bepanthenol cream for partial thickness burns.

Methods: The study was carried out in the Burn Center of a state hospital in Athens, Greece.

Explanatory versus pragmatic trial-based economic evaluations: application to alternative therapies for burns.

The debate concerning the adoption of a pragmatic or explanatory attitude to clinical trials as well as the exact points of distinction between the two attitudes, has lasted for more than 40 years. Recently, new methodological proposals have been given as a pragmatic-explanatory continuum indicator summary tool and mechanistic-practical framework to distinguish the two attitudes. In this review, we provide a guide to the literature concerning the debate regarding the choice between explanatory and pragmatic attitudes in trial-based economic evaluations, focusing on the therapies for burns.
