Postural stability and control are essential motor skills for successfully performing various activities of daily living. However, children with autism spectrum disorder (ASD) exhibit significant sensorimotor impairments. The aim of this study was to investigate the efficacy of psychomotricity training on postural control (PC) of children with ASD. We recruited thirty children (age = 8.01 ± 1.2; weight = 31.66 ± 8.1 kg; height = 129.7 ± 10.8 cm) diagnosed with ASD (intellectual quotient > 50) to participate in this study. They were divided into two groups: the experimental group (n = 16) and control group (n = 14). Children in the experimental group were trained with psychomotor activities two times a week for nine weeks. Statistic postural balance was assessed before and after intervention and on different vision conditions. The results showed that the psychomotor training significantly improved PC in standing position under different conditions when compared to the control group, in all parameters (CoPA; CoPLX; CoPLy) (p < 0.01). Our preliminary findings suggest the usefulness of the psychomotor training in children with ASD on static PC.

Background/Objectives: Despite its well-established health benefits, adherence to the Mediterranean lifestyle (MedLife) has declined globally, including in its region of origin, alongside a significant shift toward ultra-processed food consumption. Understanding the factors associated with MedLife adherence is essential for developing targeted interventions and tailored policy recommendations. As part of the MEDIET4ALL PRIMA project, this cross-sectional study aimed to comprehensively examine geo-demographic, socio-economic, psychological, behavioral, and barrier-related factors associated with and potentially contributing to MedLife adherence. Methods: Data were collected from 4010 participants aged 18 years and above across ten Mediterranean and neighboring countries using the multinational MEDIET4ALL e-survey, which included the validated MedLife index, along with various other questionnaires. Results: Results indicate that only 22% of respondents demonstrated high adherence to the Mediterranean lifestyle (MedLife), with significant variability observed across countries, age groups, education levels, and health statuses. Spain had the highest proportion of participants with high adherence (38%). Factors associated with significantly higher adherence rates include older age, living in the Mediterranean region, higher education levels, a greater awareness of MedLife principles, lower perceived barriers, normal BMI, better health status, and stable economic and marital conditions (p-values ranging from 0.04 to <0.001). Additionally, individuals with high MedLife adherence exhibited more socially and physically active lifestyles and experienced less psychological strain (p < 0.001). Regression analyses identified MedLife awareness as the strongest positive predictor of adherence (β = 0.206), followed by social participation (β = 0.194) and physical activity (β = 0.096). Additional positive contributors include life satisfaction, sleep quality, living in the Mediterranean region, age, and education (β ranging from 0.049 to 0.093). Conversely, factors that are negatively associated with adherence include sedentary behavior, living environment, and barriers such as low motivation, taste dislike, price unaffordability, limited availability, and the time-consuming nature of preparing Mediterranean food (MedFood; β ranging from −0.036 to −0.067). Conclusions: These findings indicate that fewer than one in four adults across Mediterranean and neighboring countries demonstrate high adherence to MedLife, supporting prior evidence of suboptimal adherence even within Mediterranean regions. This study identified a range of behavioral, socio-demographic, and environmental factors—both positive and negative predictors—that can help guide the design of targeted, culturally adapted interventions to promote MedLife behavior. Future research should incorporate objective measurements and longitudinal monitoring to better understand underlying mechanisms, establish causality, and develop sustainable strategies for enhancing MedLife adherence in diverse populations.

This study aimed to explore the effect of the motor game, “Clock Motor Games”, on the improvement of “Reading and Recording of Time” (RRT) in children with Grade 1 mathematical learning difficulties (MLDs). A within-school cluster-randomized intervention study was conducted with 232 children (aged 6–7 years) with limited physical education experience (0.7 ± 0.3 years). The participants were divided into two groups: a control group, which received conventional teaching on time without any additional motor activities, and an experimental group, which incorporated the concept of time with the “Clock Motor Game”, for 3 weeks. The Clock-Reading Test was administered before the intervention (T0), immediately after each session (T1), and five weeks after the intervention (T2) in both groups. The results demonstrated that the experimental group exhibited significantly greater improvements in RRT performance compared to the control group (U = 4416.5; p < 0.001; r = 0.3; medium effect). Additionally, the experimental group was more likely to show progress and less likely to experience regression or stagnation compared to the control group (25% vs. 38.4%). The findings suggest that practicing “Clock Motor Games” can positively contribute to the RRT ability in children with Grade 1 MLD.

Background/Objectives: Physical activity and sedentary behaviour represent related yet distinct movement behaviours with potentially different behavioural, psychosocial, and lifestyle correlates. However, multinational evidence examining these behaviours within the Mediterranean lifestyle framework remains limited. This study investigated correlates of physical activity and sedentary behaviour among adults from Mediterranean and neighbouring countries participating in the MEDIET4ALL survey. Methods: Data were collected from 4010 adults (37.2 ± 15.4 years; 59.5% female) across 10 Mediterranean and neighbouring countries using a standardized multilingual e-survey. Physical activity was assessed using the short International Physical Activity Questionnaire (IPAQ-SF; MET-min/week), and sedentary behaviour was assessed by daily sitting time. Hierarchical multiple linear regression analyses were conducted separately for physical activity and sedentary behaviour. Exploratory bootstrapped mediation analyses examined whether life satisfaction (SLSQ) or social participation (SSPQ) mediated associations between MEDLIFE dietary dimensions and sitting time. Results: Higher physical activity was associated with more rural living environments, lower body mass index, more favourable smoking status, higher alcohol consumption, stronger adherence to Mediterranean dietary habits, longer sleep latency, higher stress, and greater social participation (β ≈ 0.05–0.11), whereas female sex, longer sleep duration, and higher anxiety were associated with lower physical activity (β = −0.04 to −0.23); the positive association with alcohol consumption should be interpreted cautiously in light of potential residual confounding. By contrast, sedentary behaviour was positively associated with higher education, higher body mass index, and more favourable smoking-status (β ≈ 0.04–0.09) and inversely associated with better self-reported health status, Mediterranean dietary consumption patterns, life satisfaction, and social participation (β = −0.04 to −0.07). Mediation analyses showed significant but small-magnitude indirect effects for the pathways linking MEDLIFE dietary consumption patterns and MEDLIFE dietary habits with sitting time through social participation (indirect β = −0.0032 and −0.0045, respectively), which should be interpreted with caution, whereas no significant indirect effects were observed through life satisfaction. Conclusions: Physical activity and sedentary behaviour are associated with different, though partially overlapping, lifestyle and psychosocial correlates within the MEDIET4ALL framework. Social participation may represent a modest behavioural pathway linking Mediterranean dietary dimensions with lower sitting time. Given the cross-sectional design, these findings should be interpreted as associative rather than causal, but they nonetheless reinforce the importance of integrated and context-sensitive lifestyle promotion strategies.

This study evaluates the "Did You Know?" (DYK) blended learning model, a pedagogical approach combining interactive Facebook posts with traditional in-person teaching to enhance gymnastics teaching in secondary school Physical Education (PE). Forty-four secondary school students (17.20 ± 0.40 years) from a public school in Tunisia were quasi-randomly assigned to either a DYK group (n = 21) or a traditional approach (TA) group (n = 23). Over a six-week intervention, the DYK group received hybrid instruction (asynchronous online content via DYK images + in-person classes), while the TA group followed a fully in-person teaching approach. Pre- and post-tests assessed motor learning (gymnastics routine performance), knowledge retention (written test), and situational motivation (Situational Motivation Scale - SIMS). The results demonstrated that the DYK group significantly outperformed the TA group in both motor learning (p < 0.001) and knowledge retention (p < 0.001). Furthermore, the DYK group exhibited a significant increase in autonomous motivation (p < 0.001) and a decrease in controlled motivation (p < 0.05), whereas the TA group displayed opposite trends. These findings highlight the efficacy of the DYK model in improving motor, cognitive, and affective learning outcomes in gymnastics. The study advocates for the integration of structured, theory-driven blended learning strategies into PE curricula to optimize student engagement and performance.

Sleep is a multidimensional health domain influenced by behavioural, psychological, and lifestyle factors. However, multinational evidence integrating insomnia severity and multiple sleep outcomes within the Mediterranean lifestyle framework remains limited. This study examined correlates of insomnia severity and key sleep outcomes in adults from Mediterranean and neighbouring countries participating in the MEDIET4ALL survey. Data were collected from 4010 adults (59.5% female) across 10 countries using a standardized multilingual e-survey. Insomnia severity was assessed as primary outcome using the Insomnia Severity Index (ISI), while sleep characteristics were assessed using sleep duration, sleep latency, sleep efficiency, and subjective sleep quality. Regression analyses examined sociodemographic, health-related, Mediterranean dietary, movement-related, psychological, and social correlates. Exploratory statistical indirect association analyses involving life satisfaction were also conducted. Insomnia severity showed the highest explained variance among sleep outcomes (adjusted R2 ≈ 0.29). Higher insomnia severity was associated with female sex, higher body mass index, and greater depression, anxiety, and stress (β ≈ 0.15–0.17), whereas lower insomnia severity was associated with older age, better self-reported health status, higher life satisfaction, and greater adherence to Mediterranean dietary consumption patterns (β ≈ −0.04 to −0.11). Models for secondary sleep outcomes explained more modest variance and should be interpreted as exploratory. Across these outcomes, psychological well-being and distress showed the most consistent associations, while Mediterranean dietary dimensions and social participation showed smaller and outcome-specific associations. Exploratory indirect association analyses showed small but statistically significant indirect associations involving life satisfaction between Mediterranean dietary dimensions, social participation, and selected sleep outcomes, particularly sleep quality and insomnia severity. The findings confirm and contextualize established associations between sleep, psychological well-being, distress, Mediterranean lifestyle-related behaviours, and regional context within a large multinational sample. Psychological well-being and distress emerged as the most consistent correlates. Insomnia severity was the most robustly explained sleep outcome, whereas secondary sleep dimensions reflected more modest exploratory correlational profiles.
