E-coaching applications can improve people’s lifestyles; however, their impact on people from a lower socioeconomic status (low SES) is unknown. This study investigated the effectiveness of a lifestyle e-coaching application in encouraging people facing low SES disadvantages to engage in a more active lifestyle over a course of 19 weeks. In this bicountry study, 95 people with low activity level (GR: 50, NL: 45) used a mobile application linked to a wearable activity tracker. At the start and after 6 and 19 weeks, self-reported physical activity levels, attitudes, and intention towards increasing activity levels, perceived behavioral control, and wellbeing were measured. Results indicated that participants using the lifestyle e-coaching application reported significantly more often an increase in activity levels than a parallel control group. Additionally, the people using the application also more often reported increased levels of wellbeing and perceived behavioral control. Therefore, lifestyle e-coaching applications could be a cost-effective solution for promoting healthier lifestyles in low-SES populations.

The early introduction of effective nutritional educational programs is pivotal for instilling sustainable healthy behaviors. The present work aims to present a best practice example of a nutrition and overall lifestyle school-based training program, the Nutritional Adventures (“Diatrofoperipeteies”). Conducted during 2020–2022 in Greek primary schools, this synchronous, online educational initiative included two 1-school-hour activities with a nutrition instructor. Additionally, schools were randomly assigned to supplementary “at-home” supported-by-parents or “in-class” supported-by-educators educational activities. In total, n = 12,451 students of 84 primary schools participated. Parent-completed questionnaires were selected in the recruitment and post-intervention phase (40% participation rate); overall, the working sample was n = 1487 students. In the post-intervention phase, a significant increase in Mediterranean diet adherence was observed (KIDMED score: mean increment = 0.25 units; p < 0.001), particularly fruit and vegetable consumption. Time spent on physical activity increased, while screen time decreased. Students’ total quality of life significantly improved (PedsQL; mean increment = 1.35 units; p < 0.001), including on all of its subscales (physical, emotional, social, and school function). Supplementary educational activities that were supported by educators rather than parents yielded a more favorable impact on students’ lifestyle and quality of life. The Nutritional Adventures program can be regarded as a successful initiative in primary schools, yielding immediate advantages that extend beyond promoting healthy dietary habits.

Children’s dietary habits can have a key role in contributing to an improvement in their Health-Related Quality of Life (HRQoL). This study aims to assess the connection between Mediterranean diet adherence and HRQoL in a sample of Greek students, utilizing data from the DIATROFI program. The parents of 3774 students (mean age 7.8 (2.6) years) reported their children’s HRQoL and level of adherence to the Mediterranean dietary pattern at the beginning and end of the 2021–2022 school year. At baseline, most students’ adherence was characterized as moderate (55.2%) or high (25.1%). Students with moderate or high adherence tο the Mediterranean diet were less likely to report a total HRQoL below the median at baseline (OR = 0.56, 95%CI = 0.44, 0.70), along with all its dimensions (physical, emotional, social, and school functions). A one-unit improvement in KIDMED score _{(beginning–end of schoolyear)} was associated with the likelihood of an improvement in total HRQoL _{(beginning–end of schoolyear)} (OR = 1.09, 95%CI = 1.02, 1.17), emotional (OR = 1.09, 95%CI = 1.02, 1.17), and social functions (OR = 1.13, 95%CI = 1.05, 1.22), but not with physical and school functions. The health benefits of the Mediterranean diet in children may not be limited to disease prevention but also extend to their overall wellbeing.

To compare first- and second-immigrant pediatric populations with a non-immigrant pediatric population in terms of quality-of-life metrics, a cross-sectional analysis using data from the DIATROFI Program was implemented. In total, n = 2277 students (mean age: 9(4) years) from public schools in Greece participating in the 2020–2021 school year were analyzed. The students’ immigration status (first-generation/second-generation) was defined as per the standard definition. The students’ health related-quality of life (HRQoL) was assessed using a parental-perceived quality of life questionnaire. The sample included 4.8% first-generation and 21.2% second-generation immigrant students. Compared with non-immigrants, the first-generation immigrant students were more likely to have poor HRQoL (odds ratio (OR) = 2.82; 95% confidence interval (95%CI) = 11.75, 4.53), physical (OR = 1.91; 95%CI = 1.18, 3.10), social (OR = 1.94; 95%CI = 1.16, 3.22) and school function (OR = 2.52; 95%CI = 1.54, 4.13). Similar results were observed for second-generation immigrant students regarding HRQoL (OR = 1.68; 95%CI = 1.28, 2.21), physical (OR = 1.60; 95%CI = 1.23, 2.10) and school function (OR = 2.09; 95%CI = 1.58, 2.77). Children with one parent having a country of origin different that the country of residence had elevated odds of having poor emotional health (OR = 1.19; 95%CI = 0.87, 1.64). The family’s affluency level was interrelated with the connection of poor HRQoL and immigration status. The immigrant students have a poorer quality of life depending on their immigration generation and irrespective of their socioeconomic background.

During emergencies, older adults stand among the most vulnerable, facing long-lasting food insecurity and overall health issues. The “365+ Days of Care” food aid program addressed food insecurity and poor quality of life among vulnerable older adults following a devastating wildfire in Greece. Our aim was to evaluate the program’s efficiency, using a process evaluation framework and a partial cost–utility analysis. In total, n = 133 wildfire-hit residents (≥65 years) received daily tailored, pre-cooked meals and/or weekly food packages. The study outcomes were assessed from baseline to 12 months later. Focus groups and interviews (n = 30), researcher observations, and questionnaires were used to assess the beneficiaries’ perception of the initiative. Within the 12-month follow-up period, food insecurity and malnutrition risk decreased, whereas Mediterranean diet adherence; quality of life; and physical, social, and mental health were improved (p < 0.05). A one-point increase in food insecurity was positively associated with improved quality of life, general health, limitation in activities, body pain, vitality, and pain/discomfort (p’s < 0.05), and it was marginally associated with mobility, anxiety/depression, and self-evaluated health status (p’s < 0.1). Quantitative and qualitative data characterized it as successful, acceptable, beneficial, and of high quality. The partial cost–utility ratio was one QALY gained per EUR 22.608. The utilization of well-designed food aid programs during emergencies can alleviate food insecurity and improve quality of life in older adults.

Providing meals of high nutritional value should be the principal objective of large-scale school-based food aid programs. This study aimed at highlighting the nutritional value of meals distributed in the school-based food assistance DIATROFI Program by comparing them to their commercially available counterparts. For the purpose of this study, n = 13 DIATROFI meals and n = 50 commercial products from the 2016–2017 school year, and n = 12 DIATROFI meals and n = 40 commercial products from the 2022–2023 school year were selected. The protein, carbohydrate, total sugar, dietary fiber, total fat, sodium/salt content, and fatty acid methyl ester profile of DIATROFI meals were estimated through recipe simulation and national/international food databases, and verified through laboratory analyses while the relevant information was extracted from the label for commercial products. As verified by laboratory analyses and in comparison with food labels, most DIATROFI meals had lower total fat, saturated fatty acid, and sugar content, and most had higher dietary fiber content during both years. Many recipes’ nutrient profiles also improved over time. DIATROFI meals present significant advantages over available commercial products. Such tailored-made school meals can prove to be advantageous in terms of nutrition profile compared to commercially available, which have yet to be impacted by food reformulation.
