Assessing the Validity of Front-of-Pack Nutrition Labels for Evaluating the Healthiness of Mediterranean Food Choices: A Global Comparison.

In response to growing public health concerns, governments worldwide have implemented various nutrition labelling schemes to promote healthier eating habits. This study aimed to assess the consistency and effectiveness of these labels in an out-of-home context, specifically focusing on restaurant, hospitality, and institutional food service settings. In total, 178 different dishes from Spain were analysed using labels from the Mazocco method, the UK's traffic light system, the Health Star Rating (Australia), Nutri-Score (France), multiple traffic lights (Ecuador), and warning labels (Chile and Uruguay).

Factors influencing dietary inequalities among adolescents in Madrid and Bilbao: a qualitative research project.

Objective: To describe the design and methodology of a qualitative study to explore the main factors influencing dietary inequalities in adolescents in Madrid and Bilbao, Spain.

Method: The study area included six neighborhoods (three in each city) of different socioeconomic status (SES): low, medium, and high. We sampled 12 secondary schools (six in each city: two per socioeconomic level).

Correlates of eating behaviors in adolescence: a systematic review of qualitative studies.

Context: Nutrition plays a critical role in adolescence. Adolescents are vulnerable to the impact of different factors that distance them from healthy habits, increasing their risk of chronic diseases in adulthood. Qualitative methodologies allow for a better understanding of these factors.

[Factors related to sleep quality in Emergency Medical Technicians and their sleep habits during COVID-19 pandemic.].

Objective: Emergency Medical Technicians (EMTs) show a high prevalence of sleep problems. Adding to these problems, another factor appeared two years ago: the COVID-19 pandemic. The objectives of this study were to describe the sleep quality and habits in a sample of EMTs in Spain during COVID-19 pandemic considering the factors related to them.

Residents' Insights on Their Local Food Environment and Dietary Behaviors: A Cross-City Comparison Using Photovoice in Spain.

Perceptions of local food environments and the ability of citizens to engage in participatory research may vary, even if participants share similar cultural and socioeconomic contexts. In this study, we aimed to describe participants' narratives about their local food environment in two cities in Spain. We used the participatory methodology of Photovoice to engage participants in Madrid ( = 24) and Bilbao ( = 17) who took and discussed photographs about their local food environment (Madrid; = 163 and Bilbao; = 70).

Exploring the effect of two different teaching strategies on first-year nursing students' understanding of nutritional concepts: A mixed-method approach.

Aim: The aim of the study was twofold. First, to explore understanding difficulties in nutritional concepts among nursing students and second, to analyse the effect of two teaching strategies on the level of understanding.

Background: Previous studies have pointed out the need to improve the nutritional care education offered to undergraduates in health sciences.

Residents' perceptions of their local food environment in socioeconomically diverse neighborhoods: A photovoice study.

The influence of unhealthy food environments on residents' eating behaviors has been previously documented. Yet, socioeconomic differences across areas are less studied. Participatory studies provide relevant knowledge to better inform future nutrition interventions.

n-3 Fatty Acid Supplementation During 4 Weeks of Training Leads to Improved Anaerobic Endurance Capacity, but not Maximal Strength, Speed, or Power in Soccer Players.

Omega-3 fatty acid (n-3 FA) supplementation could promote adaptation to soccer-specific training. We examined the impact of a 4-week period of n-3 FA supplementation during training on adaptations in 1RM knee extensor strength, 20-m sprint speed, vertical jump power, and anaerobic endurance capacity (Yo-Yo test) in competitive soccer players. Twenty six soccer players were randomly assigned to one of two groups: n-3 FA supplementation (n-3 FA; n = 13) or placebo (n = 13).

Basketball Performance Is Related to Maturity and Relative Age in Elite Adolescent Players.

During a national championship, the anthropometric, physiological, and maturation characteristics of 13- to 14-year-old players of elite basketball teams and their association with sport performance were analyzed. Body parameters (weight, height, skinfold thicknesses, and lengths) were measured and physiological capacities assessed by sprint (20 m) and jump tests (i.e.

Relationship between the relative age effect and anthropometry, maturity and performance in young soccer players.

The presence of the relative age effect (RAE) has been widely reported; however, its underlying causes have not yet been determined. With this in mind, the present study examined if anthropometry and performance were different amongst older and younger soccer players born in the same year. Eighty-eight young soccer players participated in the study (age 9.

Influence of nutrient intake on antioxidant capacity, muscle damage and white blood cell count in female soccer players.

Background: Soccer is a form of exercise that induces inflammatory response, as well as an increase in free radicals potentially leading to muscle injury. Balanced nutritional intake provides important antioxidant vitamins, including vitamins A, C and E, which may assist in preventing exercise-related muscle damage. The purpose of the present study was to determine the effect of macro/micronutrient intake on markers of oxidative stress, muscle damage, inflammatory and immune response in female soccer players.

Metabolic impact of a soccer match on female players.

The aim of this study was to examine the metabolic effect of a female soccer match in elite and sub-elite teams. Blood samples were taken (24 h before, immediately after and 18 h after official soccer matches) to determine haematological, electrolytic and hormonal variables, as well as the levels of cell damage and oxidative stress in 14 elite and 14 sub-elite players. Our results show increases in white blood cell count (P < 0.

Cell damage, antioxidant status, and cortisol levels related to nutrition in ski mountaineering during a two-day race.

The aim of this study was to measure the effect of nutrition on cell damage, antioxidant enzymes, and cortisol during a two-day ski mountaineering competition. Twenty-one male skiers participated in the study. Creatine kinase (CK), aspartate aminotransferase (AST), alanine aminotransferase (ALT), γ-glutamyl transpeptidase (GGT), lactate dehydrogenase (LDH), alkaline phosphatase (AP), cortisol and C-reactive protein (CRP), glutathione peroxidase (GPx) and reductase activities (GR) and C-reactive protein (CRP) levels, total antioxidant status, and cortisol levels were measured in serum the day before and immediately after the race.
