In their attempt to achieve the optimum weight or body shape for their activity, athletes frequently use harmful weight-control practices that may lead to the development of disordered eating or eating disorders. These practices are linked to several medical and mental consequences that may be more serious in adolescent athletes, as their bodies must meet both intensive growth demands and training requirements at the same time. Among other consequences, adolescent athletes may be at nutritional risk, due to their high nutrient needs and unhealthy eating behaviors. A literature review was conducted to examine the main nutritional risks and malnutrition issues faced by adolescent athletes that present disordered eating attitudes or eating disorders. Most studies refer to adult elite athletes, however research on adolescent athletes also indicates that the most common nutritional risks that may arise due to disordered eating include energy, macronutrient and micronutrient deficiencies, dehydration and electrolyte imbalances and changes in body composition that may lead to menstrual abnormalities, and decreased bone mass density. Educational programs and early detection of disordered eating and eating disorders are crucial to avoid the emergence and ensure timely management of nutrition-related problems in the vulnerable group of adolescent athletes.

This study examined the weight pressures within the gymnastics environment and explored associations between these pressures and eating disorder (ED) symptoms in adolescent female gymnasts. One hundred and forty-seven competitive gymnasts and 122 recreational-level gymnasts (11–17 years old) completed the Eating Attitudes Test (EAT-26), the Weight-Pressures in Sport-Females (WPS-F), the Social Desirability Scale (SDS) and provided information on their training. It was found that 16.3% of competitive gymnasts and 7.4% of non-competitive gymnasts scored ≥20 in EAT-26, indicating disordered eating behavior. Competitive gymnasts scored higher than non-competitive in the total score of EAT-26 (p = 0.027), as well as in the total score of WPS-F, the sport and coaches weight pressures sub-scale and the appearance and performance weight pressures sub-scale (p < 0.001). Multiple regression analyses indicated that sport and coaches weight pressures, appearance and performance weight pressures and body mass index accounted for 30.3% of the variance of EAT-26 in competitive gymnasts, while the appearance and performance weight pressures sub-scale accounted for 16.3% of the variance of EAT-26 in non-competitive gymnasts. Sport and coaches weight pressures are associated with ED in competitive gymnasts, while body appearance and performance demands correlate with ED in female gymnasts irrespective of competitive level.

Chronic kidney disease (CKD) is a serious public health problem that, in recent decades, has taken on significant dimensions with serious effects on the quality of life (QoL) of patients. The purpose of this cross-sectional study is to evaluate the QoL of a sample of hemodialysis patients in Greece and the possible correlations with socio-economic and anthropometric factors, as well as with adherence to the Mediterranean Diet (MD). During September–November 2019, one-hundred and five (n = 105) patients with end-stage CKD (63.4 ± 13.09 years of age) who were regularly monitored in five public and private hemodialysis units in the region of Attica, completed a demographic questionnaire, the MedDietScore questionnaire, and the KDQOL-SF questionnaire. Females presented worse QoL than males (p < 0.05), and older patients presented worse QoL than younger patients (p < 0.01). Patients of higher educational status presented better QoL scores than those of lower educational status (p < 0.01), while those with low financial status presented lower QoL scores than patients of middle and high financial status (p < 0.01). Obese patients had lower QoL scores than overweight patients (p < 0.05), and overweight males scored higher than normal weight males (p < 0.05). Age was negatively correlated to the total and most of the scales of QoL (p < 0.01). A majority of the patients (90.5%) showed a moderate adherence to MD, although “work status” was the only QoL scale that was correlated to MD. Age, educational status and financial status accounted for 28.1% of the variance in the KDQOL-SF total score. Hemodialysis patients need support in various levels, such as social, financial and educational, as well as nutritional counseling to adopt a balanced diet and maintain a healthy weight, in order to achieve a better quality of life.

Background: Despite the well‐known benefits of the Mediterranean diet (MD), low adherence is observed globally, highlighting the need to investigate the underlying causes of this trend. Large‐scale, periodically repeated surveys, such as the European Health Interview Survey (EHIS), could be useful for the investigation of the factors that influence adherence to healthy dietary patterns. National EHIS‐3 in Greece was designed to collect data on the consumption of all food groups, making it possible to determine adherence to MD.Methodology: This study aimed to investigate the socioeconomic factors that influence MD adherence by conducting a secondary data analysis from 7706 participants aged 15–85 years who participated in the 2019 national EHIS. MD adherence was evaluated by MedDietScore. Bivariate comparisons between the score tertiles and socioeconomic groups were performed. Logistic regression analyses were used to estimate the association between MedDietScore tertiles and demographic and socioeconomic factors, using high adherence as the reference category. Finally, cluster analysis was applied to identify the most significant factors in relation to the classification of the participants in MD adherence groups.Results: Educational level, followed by income status, emerged as the most significant factor associated with adherence to MD. Individuals who have attained only primary education had a 3.80 times higher likelihood of presenting low MD adherence instead of high MD adherence compared to persons with tertiary education. Individuals in the lower income group had 2.53 times higher odds of being in the low MD adherence instead of high MD adherence than individuals in the higher income group. These relationships remained statistically significant after adjusting for confounding factors. The group that most frequently adhered to high MD (53.4%) comprised individuals who had tertiary education, higher income, and were couples without children. Conversely, those with primary or secondary education who are single parents or live in one‐person households and fall into the lower and medium income groups are most likely to have low MD adherence (44.8%).Conclusions: Public policies to promote MD adherence should consider socioeconomic factors. Integrating questions to evaluate adherence to dietary patterns into EHIS would allow for future intercountry and longitudinal comparisons.

Food insecurity comprises a major global public health threat, as its effects are detrimental to the mental, physical, and social aspects of the health and well-being of those experiencing it. We performed a narrative literature review on the magnitude of global food insecurity with a special emphasis on Greece and analyzed the major factors driving food insecurity, taking into consideration also the effect of the COVID-19 pandemic. An electronic search of international literature was conducted in three databases. More than 900 million people worldwide experience severe food insecurity, with future projections showing increasing trends. Within Europe, Eastern and Southern European countries display the highest food insecurity prevalence rates, with Greece reporting a prevalence of moderate or severe food insecurity ranging between 6.6% and 8% for the period 2019–2022. Climate change, war, armed conflicts and economic crises are major underlying drivers of food insecurity. Amidst these drivers, the COVID-19 pandemic had a profound impact on food insecurity levels around the globe, through halting economic growth, disrupting food supply chains and increasing unemployment and poverty. Tackling food insecurity through addressing its key drivers is essential to any progress towards succeeding the Sustainable Development Goal of “Zero Hunger”.

Recently, besides the focus on the medical diagnosis and therapeutic interventions for food allergy (FA), the psychosocial aspects of this frequent condition have also been investigated. The current systematic review aimed to explore and synthesize the scientific evidence published from January 2015 to April 2022 on Health-Related Quality of Life (HRQoL) among children and adolescents with FAs. Twenty-eight research studies were included in the review, which was conducted on three databases (PubMed, Scopus and Cochrane Library). In most studies, the scores indicate an average level of HRQoL for children and adolescents with FAs, with girls and older children being more negatively affected than boys and younger ones, respectively. Few studies compared HRQoL between children with FA and healthy children, with 3 of them showing worse HRQoL for children with FAs. Immunotherapy has been found to improve the QoL of children with FAs. Anaphylaxis history, number of FAs, additional allergies, number and severity of symptoms were identified as the main factors with a negative impact on QoL. More comparative studies on the HRQoL of children and adolescents with FAs and healthy populations or children with other chronic diseases are required in order to improve QoL of children with FAs.
