Objective: The study aimed to analyze the relationship between screen time (ST) duration, body weight status (BWS), and selected lifestyle behaviors in children aged 10–12. Methods: A cross-sectional study of 7763 (50.8% girls) Polish schoolchildren was conducted in 2023–2024. Data on ST, physical activity (PA), sleep duration (SD), frequency of consumption of unhealthy foods, family meals (FM), and sociodemographic data were collected using a paper questionnaire. Anthropometric data were obtained from measurements; body mass index (BMI) was used to assess BWS, and the waist-to-height ratio to measure central obesity. A logistic regression model was performed to assess the effect of unhealthy food consumption, FM, BWS, PA level, and SD on the odds of excessive ST (>2 h/day). Results: Girls were less likely to extend ST than boys (OR: 0.78; 95% CI: 0.70–0.86). Increased PA had a limiting effect on the dependent variable (moderate OR: 0.64; 95% CI: 0.53–0.77; vigorous OR: 0.37; 95% CI: 0.31–0.45). Sleeping 6–8 h per day was associated with a 41.6% increase in prolonged ST (OR: 1.42; 95% CI: 1.27–1.57). Overweight/obese individuals were 39.6% more likely to exceed ST compared to normal-weight peers (OR: 1.40; 95% CI: 1.16–1.68). Living in a village and a smaller city increased the odds of excessive ST (OR: 1.12; 95% CI: 1.07–1.41 and OR: 1.18; 95% CI: 1.03–1.34). Conclusions: Excessive body mass and unhealthy dietary habits, particularly sugary beverages, have been identified as significant risk factors for excessive ST. Optimal SD, high PA, and regular FM might have a protective effect on ST. This knowledge will contribute to designing more tailored and effective educational interventions promoting healthy lifestyles in children. Full article

Background/Objectives: Use of social media among college students is ubiquitous. Excessive use of social media has been linked to distractions, reduced academic focus, and poor mental health outcomes such as anxiety and depression. The determinants of social media use among college students are not well understood. Hence, the purpose of this study was to conduct a scoping review on the behavioral, demographic, and psychosocial determinants, explore theoretical frameworks, and suggest evidence-based recommendations. Methods: This scoping review was conducted between January 2024 and May 2025 following PRISMA-ScR guidelines, using MEDLINE (PubMed), CINAHL, and ERIC databases. Peer-reviewed studies were included if they focused on college students (ages 18–30), investigated determinants of social media use, and met predefined inclusion criteria. Results: A total of 22 studies met the inclusion criteria. Studies were conducted in Bangladesh, Canada, China, Egypt, India, Nigeria, Pakistan, Saudi Arabia, Turkey, and the United States, and the majority used cross-sectional designs (n = 20). A consistent finding across the reviewed studies was the strong association between social media overuse and symptoms of depression, anxiety, stress, and emotional dysregulation. Very few theoretical frameworks for understanding the determinants of social media were used. According to the reviewed studies, factors such as fear of missing out, sleep quality, and prolonged social media use consistently emerged as significant predictors of adverse mental health outcomes (p < 0.05). Conclusions: In this study, problematic social media use (PSMU) was linked to increased mental health issues, suggesting that students frequently engage in social comparison and experience feelings of missing out (FoMO), which exacerbate emotional distress. There is a need for integrated approaches in addressing PSMU within educational environments, particularly in fostering healthier digital habits among students. There is a need to conduct more concerted research using longitudinal designs and contemporary theoretical frameworks in this area. Full article

Background: Lipid management is a key aspect of secondary atherosclerotic cardiovascular disease (ASCVD) prevention. However, real-world studies show that ~72–88% of patients with ASCVD fail to meet their low-density lipoprotein cholesterol (LDL-C) target. Nonstatin agents are available as add-on therapies that can be utilized when maximally tolerated statins are insufficient to achieve LDL-C goals. This retrospective study aimed to evaluate the current prescribing habits of nonstatins as add-on therapy to statins for secondary ASCVD prevention at a federally qualified health center (FQHC). Methods: Patients were included if they had a history of clinical ASCVD, ≥1 lipid panel obtained during the study period, and were prescribed any intensity statin. Results: Among 398 included participants, 11.1% were prescribed nonstatin therapy and 35.9% were meeting a LDL-C target of <70 mg/dL. There was a significant association between being prescribed ezetimibe based on the type of healthcare coverage (p = 0.04) and a higher number of ASCVD qualifying indications (p < 0.01). Conclusions: Overall, nonstatins were found to be underutilized for LDL-C management in this underserved population. Future initiatives should target ways to optimize nonstatin therapy to optimize secondary ASCVD prevention. Full article

Water consumption in adults usually reaches lower levels than the recommendations, and evidence of the beverage consumption habits of women in the stages around menopause is scarce. The aim of this study was to assess the consumption of beverages and to determine how physical, psychological, and environmental factors modify the hydration habits of reproductive-age and postmenopausal women in the northeast of Mexico. We carried out a cross-sectional study of 40–65-year-old female (n = 690) residents in the metropolitan area of Monterrey, Nuevo León state, Mexico, who were classified as reproductive (n = 263) and postmenopausal (n = 427). Anthropometrics, including body composition, beverage consumption, physical activity, and physical, psychological, and environmental factors, were assessed. There were no differences between the BMI and waist-to-height ratio of reproductive-age and postmenopausal women. The total daily beverage consumption did not differ between reproductive-age and postmenopausal women, with an average beverage consumption of 2723–2915 g/day. A third of the women studied consumed less than 1.5 L/day, and another third—mainly the younger participants—consumed between 1.5 and 2.0 L/day. The most consumed beverage was plain water, followed by regular soda, flavored beverages, coffee, and diet soda. Consumption of regular soda, flavored beverages, and milk was higher among reproductive-age women. The postmenopausal women indicated a higher consumption of plain water and juices. Similar effects of physical and psychological factors and environmental temperature on the beverage consumption of reproductive and postmenopausal women were observed. Physical activity, maximum daily temperature, and body composition were the factors that conditioned beverage intake. Full article

The insect gut contains a complex and diverse microbial community, and the composition of the insect gut microbial community is influenced by multiple factors such as the host’s genetics, dietary habits, and the external environment. The host’s immune system maintains the stability and balance of the microbial community through a number of mechanisms. The microorganisms in this community play key roles in the nutrient metabolism, detoxification, immune regulation, development, and behaveior of insects. In recent years, the relevant literature has reported advances in the study of insect gut microbes, indicating the potential applications of insect gut microbes in several fields. The aim of this review is to provide a comprehensive overview of the current information on the structure of insect gut microbial communities and complex host–microbe–environment interactions. The diversity of insects’ gut microbial communities and the functions of their gut microbes are revealed. By studying insect gut microbial communities, we can gain insights into the functions of these microbes in the host and explore the causal relationships between them and the host’s physiology and behavior. This will not only help us to understand the mechanism of action of the microbiome, but also provide a basis for the development of innovative biotechnology based on insect gut microbes. This research has significant theoretical value in academia and also has a wide range of applications in agriculture, environmental protection, industrial production, and healthcare. Full article

One of the most common issues encountered in the rehabilitation of timber-structured buildings is the crushing of elements subjected to compression perpendicular to the grain. This crushing results in differential settlements that decrease comfort and, in some cases, compromise the habitability of the building. This study analyzed a reinforcement method involving the lateral confinement of timber members using two metallic side plates. Experimental tests were conducted with various configurations of the bolts used to fix the plates. In addition, several finite element models were developed and validated to extend the scope of the analysis virtually. An initial reinforcement proposal was examined, in which the metal plates were allowed to move vertically with the wood’s deformation. This setup achieved only a 26% reduction in deformation. Subsequently, an enhanced reinforcement system was tested, wherein the plates were anchored to the lower vertical stud, preventing their vertical movement. This configuration significantly enhanced performance, achieving maximum deformation reductions of up to 53%. Finally, in the improved reinforcement system, the load distribution among the bolts was analyzed to support their structural design. Full article

This study aimed to identify and analyse the main difficulties faced by family farmers in producing and supplying vegetables through short food supply chains. Semi-structured interviews were conducted with seven family farmers in a large city in southern Brazil. We sought to include at least one farmer supplying each of the main identified outlets: schools, restaurants, supermarkets, street markets, and consumer groups. Contacts were obtained through rural producer organisations. Data were recorded, transcribed, and analysed using thematic analysis. Three groups of difficulties emerged: (i) production—including seasonality, pest, and disease management, climate-related losses, and limited technical support; (ii) sales—such as price competition, logistical challenges, and inconsistent demand; and (iii) consumption—particularly low consumer habits regarding vegetable purchase and preparation, and preference for non-seasonal products. The study concludes that the main challenges to strengthening short food supply chains are the limited engagement of young people in farming, lack of specialised technical assistance, climate-related risks, bureaucratic barriers, and the high costs of organic certification. Farmers also reported logistic difficulties and constraints in supplying restaurants due to demand for a narrow range of products disregarding seasonality. At the consumer level, habits shaped by conventional food systems emerged as obstacles. Strategies such as alternative markets, farmer organisations, supportive public policies, and initiatives to promote cooking skills and consumer awareness are key to enhancing resilience and expanding the supply of healthy foods.

Irritable Bowel Syndrome (IBS) and Metabolic dysfunction-associated fatty liver disease (MAFLD) have traditionally been viewed as disorders of distinct organ systems. IBS is a gut–brain axis disorder characterized by abdominal pain, altered bowel habits, and psychological comorbidities. MAFLD, recently redefined to emphasize its metabolic underpinnings, is the hepatic manifestation of systemic metabolic dysfunction. Growing evidence suggests that these conditions share overlapping pathophysiological mechanisms linked through disruption of the gut–liver–brain axis (GLBA), including psychological stress, gut dysbiosis, impaired intestinal permeability, systemic inflammation, and altered neuroendocrine signaling. Neuroimaging studies further reveal functional alterations in brain regions responsible for interoception, emotional regulation, and stress responsiveness in both disorders. This narrative review explores how psychological distress influences the onset and progression of IBS and MAFLD via GLBA dysfunction and stress-induced epigenetic reprogramming. A targeted literature search of major biomedical databases, supplemented by manual screening, identified relevant observational, clinical, neuroimaging, and molecular studies. Findings indicate that chronic psychological distress activates the hypothalamic–pituitary–adrenal (HPA) axis, elevates cortisol, disrupts gut microbiota, and reduces vagal tone; amplifying intestinal permeability and microbial translocation. These changes promote hepatic inflammation and gastrointestinal symptoms. Stress-related epigenetic modifications further impair GLBA communication, while psychological and lifestyle interventions may reverse some of these molecular imprints. Recognizing the shared neuromodulation and epigenetic mechanisms that link IBS and MAFLD opens promising avenues for integrated therapeutic strategies targeting the GLBA to improve outcomes across both conditions.

This study develops and operationalizes a multi-dimensional framework for sustainable building retrofit that aligns with national 2050 net-zero objectives. First, we conduct a scoping review of international standards (e.g., ISO), sustainability reporting guidelines (GRI G4), and peer-reviewed studies to define an indicator system spanning three pillars—environmental (carbon neutrality, resource circulation, pollution management), social (habitability, durability/safety, regional impact), and economic (direct support, deregulation). Building on this structure, we propose a transparent 0–3 rubric at the sub-indicator level and introduce the Sustainable Building Retrofit Index (SRI) to enable cross-case comparability and over-time monitoring. We then apply the framework to seven countries (United States, Canada, United Kingdom, France, Germany, Japan, and South Korea), score their retrofit systems/policies, and synthesize results through radar plots and a composite SRI. The analysis shows broad emphasis on carbon neutrality and habitability but persistent gaps in resource circulation, pollution management, regional impacts, and deregulatory mechanisms. For South Korea, policies remain energy-centric, with relatively limited treatment of resource/pollution issues and place-based social outcomes; economic instruments predominantly favor direct financial support. To address these gaps, we propose (i) life-cycle assessment (LCA)–based reporting that covers greenhouse gas and six additional impact categories for retrofit projects; (ii) a support program requiring community and ecosystem-impact reporting with performance-linked incentives; and (iii) targeted deregulation to reduce uptake barriers. The paper’s novelty lies in translating diffuse sustainability principles into a replicable, quantitative index (SRI) that supports benchmarking, policy revision, and longitudinal tracking across jurisdictions. The framework offers actionable guidance for policymakers and a foundation for future extensions (e.g., additional countries, legal/municipal instruments, refined weights). Full article

Children are more vulnerable to the adverse effects of pesticides due to physiological factors and behavioral habits. This study aimed to evaluate the impact of pesticide exposure on telomere length (TL) and the enzymatic activity of acetylcholinesterase (AChE), butyrylcholinesterase (BuChE), and β-glucuronidase (β-Glu) in children ages 6 to 12 from an agricultural area in Mexico. A cross-sectional, descriptive, and analytical study was conducted involving 471 children. Blood samples were collected to assess TL through qPCR and enzymatic activity using established protocols. A pesticide exposure index (PEI) was developed incorporating biomarker levels, urinary dialkylphosphates (DAP), and proximity to farmland. No significant differences were observed in AChE activity across communities; however, BuChE activity was significantly higher in agricultural communities, while β-Glu activity varied among communities. Notably, children aged 6 in agricultural areas showed TL values similar to 12-year-old children in the reference community. Adjusted regression models revealed significantly shorter TL in children from agricultural communities and in children with moderate to high PEI. The findings indicate that chronic pesticide exposure was associated with telomere shortening in children, suggesting accelerated biological aging and potential genomic instability during critical developmental periods.

Background/Objectives: Water-soluble vitamins are essential micronutrients requiring regular dietary replenishment due to minimal body storage capacity. Medical students.; despite their health knowledge, may be at risk for subclinical deficiencies due to academic stress and life-style factors. This study assessed water-soluble vitamin status to evaluate screening needs in this educated population. Methods: A cross-sectional study was conducted among 91 healthy medical students (age 18–23 years) at UAE University from September 2023 to January 2024. Serum levels of folate (B9), cobalamin (B12), and ascorbic acid (Vitamin C) were measured using validated high-performance chemiluminescent immunoassays. Demographic, anthropometric, dietary, and lifestyle data were collected via structured questionnaires. Statistical analyses included multivariate logistic regres-sion, correlation analyses, and receiver operating characteristic (ROC) curves. Results: Among the participants (70.3% female; mean age 19.8 ± 1.4 years; BMI 23.2 ± 2.9 kg/m²), vita-min C showed the highest prevalence of suboptimal levels at 7.7% (7/91 participants), comprising 2.2% with deficiency (<28 µmol/L, n = 2) and 5.5% with insufficiency (28–40 µmol/L, n = 5). Mean vitamin C was 56.7 ± 14.8 µmol/L. Vitamin B12 insufficiency (200–300 pg/mL) affected 9.0% (8/89) of students, with a mean of 485.3 ± 165.0 pg/mL. A non-significant trend toward higher insufficiency rates was observed among female students. No deficiencies were observed for folate (mean 14.1 ± 4.9 ng/mL). Multivariate analysis identified low fruit/vegetable intake (OR 4.8; 95% CI: 1.3–17.6; p = 0.018); high stress scores (OR 3.2; 95% CI: 1.1–9.4; p = 0.033); and female gender (OR 2.9; 95% CI: 0.9–9.1; p = 0.071) as predictors of suboptimal vitamin C. Vitamin C levels correlated positively with dietary quality (r = 0.412; p < 0.001) and negatively with stress scores (r = −0.241; p = 0.031). Despite being a health-educated population, nearly 10% of medical students demonstrated suboptimal water-soluble vitamin levels, particularly vitamins C and B12. Conclusions: These findings support implementing targeted screening programs focusing on high-risk groups, including students with poor dietary habits, high stress levels, or specific gender-based risks.

The transition to university is a critical period for establishing lifelong health habits, particularly in Saudi Arabia, where non-communicable diseases linked to lifestyle are increasingly prevalent. To address this, our study sought to comprehensively assess lifestyle behaviors, mental health status, and their combined impact on health-related quality of life (HRQoL) among students at King Khalid University. We conducted a cross-sectional study between September 2024 and February 2025, recruiting 865 undergraduates via a two-stage stratified random sampling technique. Data were collected using a validated online questionnaire that included the FANTASTIC lifestyle and EuroQol 5-Dimension 3-Level (EQ-5D-3L) instruments. Our study population exhibited a significant health burden; 37.6% were overweight or obese, 55.9% reported anxiety or depression, and 36.1% experienced pain or discomfort. Although the mean lifestyle score was generally positive, regression analysis revealed that anxiety/depression was the strongest predictor of a poorer lifestyle (OR = 2.94, 95% CI: 2.02–4.28). This study concludes that a profound negative association exists between mental health, lifestyle, and overall HRQoL, highlighting the urgent need for integrated wellness policies and support systems within the university setting to address these interconnected challenges.

Background/Objectives: Developmental Coordination Disorder (DCD) affects approximately 5% of children globally and is characterized by motor difficulties that can negatively impact physical activity levels and increase the risk of obesity. Understanding the behavioral and physiological profiles of children with DCD is essential for early intervention. This cross-sectional study compared physical activity, dietary habits, and obesity indicators between children with DCD and their typically developing (TD) peers. Methods: A total of 243 children (134 boys, 109 girls) aged 6.65 to 11.65 years (M = 9.50, SD = 1.38) from two mainstream schools in the Chartered Community of Navarre, Spain, participated in the study. Children with conditions that could explain poor motor development were excluded based on DSM-5 Criterion D. Motor competence was evaluated using the FUNMOVES (n = 243) and MABC-2 tools (n = 49). Physical activity was assessed using the Physical Activity Questionnaire for Children (PAQ-C), dietary habits with the Krece Plus questionnaire, and obesity indicators through bioimpedance analysis (Body Mass Index and body fat percentage). Regression analyses were adjusted for age and sex. Results: Children classified with probable DCD (pDCD) using FUNMOVES showed significantly higher BMI (95% CI: 0.96 to 4.30 kg/m²) and body fat percentage (95% CI: 3.99 to 10.24%) than TD peers. Differences in physical activity were not statistically significant between DCD and TD (95% CI: −0.68 to 0.01. No significant differences were found in dietary quality. When assessing motor development with MABC-2, the results followed similar trends but lacked statistical significance. Conclusions: Children with DCD are at increased risk of overweight and obesity, primarily due to lower physical activity rather than dietary differences. Early identification and targeted interventions are essential to promote healthier lifestyles in this population. Full article

For aquaculture systems, maximizing feed efficiency is a major challenge since it directly affects growth rates and economic sustainability. Feed is one of the largest costs in aquaculture, and feed waste is a significant environmental issue that requires effective management strategies. This paper suggests a novel approach for optimal fish feeding in pond aquaculture systems that integrates vision language models (VLMs), optical flow, and advanced image processing techniques to enhance feed management strategies. The system allows for the precise assessment of fish needs in connection to their feeding habits by integrating real-time data on biomass estimates and water quality conditions. By combining these data sources, the system makes informed decisions about when to activate automated feeders, optimizing feed distribution and cutting waste. A case study was conducted at a profit-driven tilapia farm where the system had been operational for over half a year. The results indicate significant improvements in feed conversion ratios (FCR) and a 28% reduction in feed waste. Our study found that, under controlled conditions, an average of 135 kg of feed was saved daily, resulting in a cost savings of approximately $1800 over the course of the study. The VLM-based fish feeding behavior recognition system proved effective in recognizing a range of feeding behaviors within a complex dataset in a series of tests conducted in a controlled pond aquaculture setting, with an F1-score of 0.95, accuracy of 92%, precision of 0.90, and recall of 0.85. Because it offers a scalable framework for enhancing aquaculture resource use and promoting sustainable practices, this study has significant implications. Our study demonstrates how combining language models and image processing could transform feeding practices, ultimately improving aquaculture’s environmental stewardship and profitability.

In sport, pain is often normalized, leading athletes to train or compete despite discomfort. This can shape their response to pain, with catastrophizing potentially triggering fear of movement, avoidance behaviors, and increased pain. While previous research has examined the relationship between pain and catastrophizing in individuals with chronic pain, few studies have explored these effects in the sports population. This study investigated the effects of a pain neuroscience educational program on catastrophizing and injury rates in youth female and male athletes. This parallel randomized trial included an intervention group (IG) and a control group (CG), both undergoing a 12-week program on healthy habits in sport. The IG received additional pain neuroscience information. Catastrophizing levels were collected before and after using the Pain Catastrophizing Scale. Injury rates were registered during the study. The results revealed a decrease in catastrophizing levels in the IG compared to baseline (p = 0.028, d = 0.32, 95%CI [0.03, 0.61]). In the IG, only males showed improvements (p = 0.041, d = 0.47, 95%CI [0.08, 0.86]). Injury rates were similar between groups (CG = 26.2%, IG = 27.8%; p > 0.05). Pain education may reduce catastrophizing in youth athletes, particularly males, although effects may vary by sex and context. Full article
