Universalism, as defined in Schwartz’s theory of basic human values, reflects a motivational orientation toward understanding, appreciation, and protection of all people and nature. This study examines the psychological foundations of ethical concern and ecological sensitivity among university students, focusing on the role of transcendence strengths. A cross-sectional correlational design was employed and a total of 1240 students from five Spanish universities participated in the study, completing validated instruments designed to assess both transcendence strengths—spirituality, gratitude, hope/optimism, humor, and appreciation of beauty—and universalism. Stepwise regression analysis identified four strengths—gratitude, appreciation of beauty, hope/optimism, and spirituality—as significant predictors of ethical concern for others and nature, explaining 20.1% of the variance. These findings contribute to the growing body of research linking positive psychological traits with ethical engagement and environmental responsibility. They also suggest that fostering transcendence-related strengths in educational settings may enhance students’ capacity for global empathy and moral development. Moreover, rather than functioning in isolation, spirituality interacts dynamically with other transcendence strengths. The study highlights the importance of integrating transcendental dimensions into sustainability discourse. Future research should explore these relationships across cultures and developmental stages to inform policy and educational practice. Full article

Background: Musculoskeletal disorders (MSDs) are a prevalent health concern among athletes, particularly female university students, who may face sport-specific, physiological, and biomechanical risk factors. In Saudi Arabia, the increasing participation of women in organized sports underscores the need to examine the burden of MSDs in this under-researched population. Objectives: This study aimed to (1) determine the prevalence of MSDs among female university student athletes, (2) identify the most commonly affected body regions, and (3) investigate associations between MSD occurrence and risk factors including sport type, warm-up practices, weekly training frequency, and history of previous injuries. Methods: A cross-sectional study was conducted among 407 physically active female university students aged 16–25 years from multiple Saudi universities. Data were collected using the validated Arabic version of the Nordic Musculoskeletal Questionnaire (NMQ) and a structured risk factor survey. Descriptive statistics, chi-square tests, and logistic regression analyses were used to examine prevalence and associated factors. Results: Among 407 participants, 65.8% reported at least one MSD in the past 12 months. The most commonly affected regions were the shoulders (43.2%), neck (41.8%), and lower back (32.2%). However, multivariate logistic regression revealed that previous injury history (OR = 2.44, 95% CI: 1.47–4.06, p = 0.001) and higher weekly training frequency (OR = 1.23, 95% CI: 1.02–1.49, p = 0.034) were significant independent predictors of MSD occurrence, while participation in team sports showed a borderline association (OR = 1.59, 95% CI: 0.95–2.67, p = 0.079). Conclusions: MSDs are highly prevalent among female university student athletes in Saudi Arabia, particularly affecting the shoulders, neck, and lower back. A history of previous injury and higher weekly training frequency are identified as significant independent predictors of MSD occurrence, while team sport participation showed a borderline association that warrants further exploration. These findings highlight the need for targeted prevention strategies that emphasize rehabilitation continuity—particularly for athletes with prior injuries—and training load management for those with higher weekly training frequency to reduce the risk of MSDs and promote long-term musculoskeletal health.

Objectives: Intolerance of uncertainty (IU) is a transdiagnostic factor implicated in emotional disorders and has recently been linked to maladaptive eating attitudes. Body dissatisfaction, a core risk factor for maladaptive eating, may represent a key pathway through which IU exerts its effects. This study examined whether body dissatisfaction has an indirect effect on the association between IU and disordered eating attitudes in female university students, controlling for body mass index (BMI) and trait anxiety. Methods: A cross-sectional study was conducted with 141 female psychology students aged 18–35 years (M = 21.23, SD = 2.31). Participants completed self-report measures of IU (Intolerance of Uncertainty Scale–Short Form), body dissatisfaction (Body Shape Questionnaire), disordered eating attitudes (Eating Attitudes Test-26), trait anxiety (State–Trait Anxiety Inventory), and reported weight and height to calculate BMI. Indirect effects were tested using bootstrapped mediation models. Results: IU was positively associated with body dissatisfaction (β = 1.139, p = 0.001), which in turn significantly predicted dieting (β = 0.126, p < 0.001) and bulimia/food preoccupation (β = 0.033, p < 0.001), but not oral control. Bootstrapped analyses showed significant indirect effects of IU on dieting (β = 0.144, 95% CI [0.047, 0.251]) and bulimia/food preoccupation (β = 0.037, 95% CI [0.010, 0.074]) via body dissatisfaction. Direct effects of IU on eating attitudes were not significant. Conclusions: IU to be associated with disordered eating attitudes primarily through body dissatisfaction, independently of BMI and anxiety. These findings extend evidence of IU as a cognitive vulnerability for eating-related psychopathology to non-clinical populations, highlighting the need for preventive interventions addressing both body image concerns and IU in female university students.

Plastic recycling has been a challenge worldwide due to various reasons, including limited profit margins, the demand for high-quality plastic reprocessing techniques to make products comparable to those from virgin materials, and challenges in sorting and processing. This problem became particularly urgent in the small towns in the U.S., where plastic waste was shipped overseas for treatment, but now it is not accepted in some countries. This study aims to understand the plastic value chain and find the necessary factors for a circular economy model of both environmental and economic settings. In this study, an educational plastics reprocessing workspace was developed with manufacturing processes such as shredding, filament extruding, 3D printing, and injection molding. A series of products was developed to increase the value of the recycled polymers. In addition, quality control of recycled polymers such as polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), and polyethylene terephthalate glycol (PETG) was examined. By collaborating with a university manufacturing lab, this work illustrates how plastics can be collected, prepared, and reprocessed, serving as a platform for student learning and community outreach. This study contributes to the body of knowledge by presenting a case-based educational model for community-level plastic recycling and reprocessing in a college town context. Full article

This study aimed to analyze the attitudes of Toledo University students toward gender and violence, as well as their sexist beliefs, considering different sociodemographic variables, and to examine the associations between these attitudes and the expression of sexism. A descriptive cross-sectional design was employed, which was conducted in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. The study population consisted of 1176 students who completed an online survey that collected sociodemographic information and incorporated the Questionnaire of Attitudes toward Gender and Violence (CAGV), along with measures of hostile and benevolent sexism derived from the Ambivalent Sexism Inventory (ASI). A descriptive analysis, an inferential analysis and a Pearson correlation were performed for the scores of the two scales used, controlling for the influence of sex and age. Among the participants, 67.1% were women and 32.0% were men. The average age was 20.1 years, with a deviation of 2.2 years, and the age was between 18 and 26 years. This work was carried out in several Faculties of the Campus. The results highlight the significant differences between the groups of men and women in both questionnaires. In general, men have higher scores than women do, so they have higher sexist attitudes and beliefs. The correlations between both questionnaires are significant among all categories. We believe that the data analyzed call for the implementation of action plans to reduce sexist behavior in university students. Universities must establish action plans against gender violence.

Background/Objective: One of the life stages that affects the consolidation of habits and health is the university stage. This transition to adulthood is associated with a decrease in physical activity, increasing the risk of cardiovascular disease. This study describes lifestyle habits related to physical activity level, diet quality, and body composition in nursing students and analyzes cardiovascular risk using the ABSI-z index. Methods: We conducted a cross-sectional study with 296 students from the Faculty of Nursing of Albacete (Spain). Physical activity was assessed via the IPAQ-SF. Body composition was measured by bioimpedance, from which BMI and ABSI-z scores were obtained as indicators of cardiovascular risk. The eating patterns of the participants were analyzed. Results/Discussion: The active students had significantly better body composition, with greater fat-free mass and muscle mass than the sedentary students, both in men (p = 0.037 and p = 0.046, respectively) and in women (p = 0.002 and p = 0.007). These findings corroborate evidence of the protective role of physical activity in maintaining metabolic health. The analysis of the ABSI-z score revealed different patterns in the distribution of body fat. High ABSI values were associated with greater abdominal girth (p < 0.001) and visceral fat (p < 0.001) in women, confirming its usefulness as an early marker of cardiovascular risk in university students. In contrast, the fulfillment of healthy dietary criteria was low, especially in the consumption of legumes (19%) and fish (25.9%). Conclusions: Regular physical activity is a determining factor in the body composition of university students, and ABSI is a good indicator of cardiovascular risk. Full article

Given the nexus between food insecurity and body dissatisfaction, a deeper understanding of this complex relationship in college students is needed. The purpose of this cross-sectional study, using the American College Health Association—National College and Health Assessment 2021 (n = 2003) at a large public university, was to explore the associations between food insecurity, personal appearance distress, and compensatory behaviors associated with body dissatisfaction. An analysis of variance with Tukey’s post hoc comparisons was performed to assess the relationship of outcomes associated with personal appearance distress by food security status. Structural equation modeling, using multivariable logistic and ordinal regression, were constructed to explore the impact of personal appearance distress, perception of body weight, weight control attempts, and dietary behaviors, adjusting for age, sex, race/ethnicity, body mass index, and food security status. Food insecurity was associated with lower grade point average, higher overall stress, and personal appearance distress. Personal appearance distress was associated with fewer servings of vegetables (p = 0.006) and fruits (p = 0.01), higher perceived body weight (p < 0.001), and more weight modification attempts (p < 0.05). The associations between food insecurity, personal appearance distress, and compensatory behaviors could extend to disordered eating behaviors, necessitating awareness and interventions from college campus programming and administration.

Introduction: Unhealthy eating habits combined with low levels of physical activity and cardiorespiratory fitness pose a serious threat to the health of young people. The aim of this research was to determine the relationship between selected components of body composition, the occurrence of eating disorders, and cardiorespiratory fitness (CRF) and physical activity levels among university students. Material and Methods: This study was conducted among 254 students at a university in Poland. It included the measurements of body height, body composition analysis using bioelectrical impedance analysis (BIA), and assessment of cardiorespiratory fitness (CRF). This research also employed the My Eating Habits (MEH) questionnaire and the short version of the International Physical Activity Questionnaire (IPAQ-SF). Results: Based on body fat percentage (BF%), nearly one-fifth (19.69%) of participants were classified as obese. According to the body mass index (BMI), over one-third had excess body weight (overweight 24.02%, obesity 10.24%), while 6.7% were underweight. Eating disorders were significantly more prevalent in women (p = 0.0002). A significant relationship was observed between eating disorders and BMI, muscle mass (MM%), skeletal muscle mass (SMM%), body fat (BF%), and visceral fat (VFATL). Higher BMI, BF%, and VFATL were associated with a greater risk of developing eating disorders. Emotional overeating was significantly less common among individuals with normal body weight compared to those who were underweight or overweight. No statistically significant associations were found between students’ physical activity levels and eating habits. However, cardiorespiratory fitness (CRF) was significantly negatively correlated with the presence of eating disorders. Conclusions: Understanding the relationship between components of body composition, eating disorders, physical activity levels, and cardiorespiratory fitness is crucial for designing effective interventions that promote a healthier lifestyle and psychological well-being among university students.

Aim: This study analyzed the concurrent validity of the Optojump infrared photocell system for estimating lower limb peak power by comparing it with the 15 s Wingate anaerobic test (WAnT) and examining relationships with sprint performance indicators. Methods: Twelve physically active university students (ten males, two females; age: 23.39 ± 1.47 years; body mass: 73.08 ± 9.19 kg; height: 173.67 ± 6.97 cm; BMI: 24.17 ± 1.48 kg·m⁻²) completed a cross-sectional validation protocol. Participants performed WAnT on a calibrated Monark ergometer (7.5% body weight for males, 5.5% for females), 30 s continuous jump tests using the Optojump system (Microgate, Italy), and 30 m sprint assessments with 10 m and 20 m split times. Peak power was expressed in absolute (W), relative (W·kg⁻¹), and allometric (W·kg^−0.67) terms. Results: Thirty-second continuous jump testing produced systematically higher peak power values across all metrics (p < 0.001). Mean differences indicated large effect sizes: relative power (Cohen’s d = 0.99; 18.263 ± 4.243 vs. 10.99 ± 1.58 W·kg⁻¹), absolute power (d = 0.86; 1381.71 ± 393.44 vs. 807.28 ± 175.45 W), and allometric power (d = 0.79). Strong correlations emerged between protocols, with absolute power showing the strongest association (r = 0.842, p < 0.001). Linear regression analysis revealed that 30 s continuous jump-derived measurements explained 71% of the variance in Wingate outcomes (R² = 0.710, p < 0.001). Sprint performance showed equivalent predictive capacity for both tests (Wingate: R² = 0.66; 30 s continuous jump: R² = 0.67). Conclusions: The Optojump infrared photocell system provides a valid and practical alternative to laboratory-based ergometry for assessing lower limb anaerobic power. While it systematically overestimates absolute values compared with the Wingate anaerobic test, its strong concurrent validity (r > 0.80), large effect sizes, and equivalent predictive ability for sprint performance (R² = 0.66–0.71) confirm its reliability as a field-based assessment tool. These findings underscore the importance of sport-specific, weight-bearing assessment technologies in modern sports biomechanics, providing coaches, practitioners, and clinicians with a feasible method for monitoring performance, talent identification, and training optimization. The results further suggest that Optojump-based protocols can bridge the gap between laboratory precision and ecological validity, supporting both athletic performance enhancement and injury prevention strategies.

Generative artificial intelligence (GenAI) holds significant potential to enhance university students’ learning. However, over-reliance on it to complete academic tasks poses a risk to academic achievement by potentially encouraging cognitive outsourcing. Despite this growing concern and an expanding body of research on GenAI usage, the mechanisms through which GenAI dependency and perceived teacher caring affect their academic achievement and self-efficacy remain underexplored. Based on the theory of media system dependence, this study explores the mechanisms through which university students’ dependency on GenAI affects their academic outcomes, focusing on the mediating role of self-efficacy and moderating role of perceived teacher caring. A survey was conducted with 418 university students from Chinese public universities who had used GenAI for an extended period. The results revealed that GenAI dependency positively predicts false self-efficacy and negatively predicts academic achievement, exhibiting a significant Dunning–Kruger effect. Perceived teacher caring moderates the relationship between GenAI dependency and self-efficacy. High perceived teacher caring mitigates the Dunning–Kruger effect but has a weak moderating effect on academic achievement. These findings enhance the explanatory power of the media system dependency theory in educational contexts and reveal the pathways through which GenAI dependency and teacher caring affect learning processes and outcomes. This study expands the theoretical implications of teacher caring in the digital age and provides empirical evidence to aid higher education administrators in optimising AI governance and teachers in improving instructional interventions.

Background/Objectives: This study evaluated the psychometric properties and correlates of the Screen for Disordered Eating (SDE) in the Chinese context. Eating and body image in Asian cultures differed from those in the Western context, elevating its importance in testing the validity of SDE in the Chinese context. Methods: The reliability, validity and correlates of the SDE were examined in a sample of 766 university students in Taiwan. Results: Convergent validity of the Chinese version of the SDE was demonstrated with high correlation (r = 0.664, p < 0.001) and satisfactory consistency (κ = 0.413, p < 0.001) with the Sick, Control, One Fat, and Food (SCOFF) questionnaire. Substantial factor loadings were suggested, with 52% of the variance in item responses, especially for SDE4 and SDE5. Significant correlates of disordered eating were found with sex, depressive symptoms, anxiety symptoms, and experiences of childhood trauma. Conclusions: The SDE is a reliable and valid screening instrument for disordered eating. Health and social care practitioners can utilise the SDE to screen for disordered eating behaviours in the Chinese context, so that timely interventions can be provided. Full article

Motor skills in students can be developed or improved through regular physical activity such as walking in nature, Nordic walking, hiking, cycling and swimming. This study aimed to examine the relationship between motor skills and various anthropometric and health-related factors, and to appraise any differences in motor performance and body mass index (BMI) on a sample of university students from Croatia. A total of 122 students (73 of them in health programs and 49 in non-health programs) aged 18 to 44 years participated in the study. Motor abilities were evaluated using standardized motor tests, while body composition was assessed via bioelectrical impedance analysis, which measured fat tissue, muscle and bone mass, metabolic age, degree of obesity, total body water, and BMI. While the groups were similar in terms of BMI and weight, students in non-health-related study programs had significantly higher values across a wide array of detailed body composition measures, particularly related to fat and muscle mass. Significant negative correlations were observed between body fat percentage and trunk lift performance (r = −0.55, p < 0.01), as well as between metabolic age and trunk lift performance (r = −0.44, p < 0.01) in health students. In non-health students, the strongest negative correlation was found between body fat percentage and flexibility (r = −0.47, p < 0.01). Higher muscle mass was a positive predictor of motor performance while higher fat mass and metabolic age were significant negative predictors. These findings underscore the impact of body composition on motor performance, particularly strength and flexibility, and highlight the need for targeted preventive strategies among university students. The study supports the implementation of early interventions promoting physical activity and healthy body composition to preserve motor abilities and long-term functional health in this critical age group—especially since lifestyle habits formed during university years tend to persist into adulthood.

Background: Time-restricted eating (TRE), a dietary strategy that confines daily food intake to specific time windows, has been shown in animal models to enhance physical performance even without exercise training. However, evidence in humans under non-exercise conditions remains limited. Objective: This study aimed to investigate the effects of early TRE (eTRE; 08:00–14:00) and delayed TRE (dTRE; 12:00–18:00) on body weight, aerobic endurance, and anaerobic power in untrained adults. Methods: In a randomized crossover trial, 28 healthy university students (mean age 23.47 ± 2.87 years; 16 women) completed two 4-week interventions, eTRE and dTRE, separated by a 2-week washout. Participants did not engage in any structured exercise during the intervention period. Body weight, aerobic endurance (cycling time to exhaustion at a fixed workload), and anaerobic power (peak power output during sprint cycling) were assessed after each phase. Results: Body weight significantly decreased after eTRE (−1.56 kg; 95% CI [−2.07, −1.05]; p < 0.001; Cohen’s $d_z$ = 1.17) and dTRE (−0.61 kg; 95% CI [−1.12, −0.10]; p = 0.022; Cohen’s $d_z$ = 0.55), with a greater reduction observed in eTRE compared to dTRE (−0.95 kg; 95% CI [−1.74, −0.16]; p = 0.020). Aerobic endurance showed no significant change across phases (all p > 0.05). Anaerobic power significantly improved after both eTRE (+21.25 W; 95% CI [12.03, 30.47]; p < 0.001; Cohen’s $d_z$ = 1.10) and dTRE (+35.43 W; 95% CI [26.21, 44.65]; p < 0.001; Cohen’s $d_z$ = 1.20), and the improvement was significantly greater in dTRE compared to eTRE (+14.18 W; 95% CI [1.79, 26.57]; p = 0.025; Cohen’s $d_z$ = 0.54). Conclusions: Both early and delayed TRE independently led to weight loss and enhanced anaerobic power in the absence of an exercise intervention. eTRE was more effective for weight reduction, whereas dTRE produced greater improvements in anaerobic performance.

Violence against women and girls (VAWG) remains a critical problem within Brazilian higher education institutions, where deep-rooted cultural norms and institutional shortcomings continue to foster unsafe environments for female students. Although national and international bodies have raised concerns, few studies have thoroughly examined the layered causes of VAWG in academic settings using comprehensive analytical methods. This study aims to explore the causal factors of VAWG within Brazilian universities by applying a structured survey and analyzing the responses using the Fuzzy Synthetic Evaluation (FSE) approach. This method allows for a nuanced interpretation of the collected data by assigning weighted values to various contributing factors. The research assessed five major dimensions—individual, interpersonal, institutional, community and societal causal factors. The findings reveal that societal and institutional causes significantly contribute to VAWG, while individual factors play a comparatively minor role. These insights point to the structural and systemic nature of VAWG in academic settings, emphasizing the need for broad reforms. Based on the results, practical recommendations, including cultural reorientation, stricter institutional policies, and gender-sensitive training are recommended. By applying FSE in this context, the study offers a novel approach to evaluating and addressing gender-based violence (GBV) in higher education, contributing to a valuable model for future research and institutional policymaking. The results offer critical insights that can guide interventions to foster safer and more inclusive university environments in Brazil. Full article

Middle Eastern males face unique eating disorder (ED) risks due to cultural transitions from traditional masculine ideals that emphasized functional strength to Western aesthetic standards. Male EDs in Middle Eastern populations constitute an emerging public health concern that has received limited systematic research attention, despite increasing clinical recognition. This systematic review synthesized available epidemiological data on ED prevalence among Middle Eastern males to examine regional patterns and associated risk factors. We conducted a systematic review following PRISMA guidelines by searching PubMed, Scopus, and Google Scholar databases for studies published between 2000 and 2023 that examined EDs in males aged 15 years and above across Middle Eastern countries. Thirteen studies encompassing 5236 male participants from 11 countries met the inclusion criteria. ED prevalence demonstrated substantial variation from 2.2% to 81.4% depending on population and assessment methodology, with Gulf Cooperation Council countries showing consistently higher rates. Age-stratified analysis revealed the highest rates among adolescents aged 15–18 years (mean: 35.0%) compared to adults over 25 years (mean: 2.1%), with university students showing intermediate levels (mean: 29.0%). Muscle dysmorphia emerged as particularly prevalent among bodybuilders (5.7–81.4%), while university students showed rates of 9.7–49.1%. Depression, body dissatisfaction, and cultural transition stress were consistently identified as correlates across multiple populations. These findings underscore late adolescence as a critical risk period and highlight the urgent need for culturally adapted diagnostic tools, healthcare provider training, and region-specific prevention strategies.
