Early pregnancy loss (EPL) is a global public health concern with significant physical and psychological effects on individuals and society. The specific etiology of many EPL cases is not well understood, and first trimester maternal diet may play a role in EPL occurrence. This study aimed to examine the differences in first trimester maternal nutrient intake, nutritional habits and nutritional knowledge levels between healthy pregnant women and women who experienced EPL. A single center retrospective case-control study was conducted at a public hospital in Istanbul, Turkey between May-October 2024. The case group comprised 65 women who experienced first-time pregnancy loss. The control group included 65 healthy pregnant women in the first trimester without a previous PL history, with both groups matched for age, body mass index (BMI) and parity. Data were collected from the participants regarding their general information, dietary habits, the Quantitative Food Frequency Questionnaire (QFFQ), and the Nutrition Knowledge Level Scale for Adults (NKLSA). Dietary nutrient intakes were evaluated on the basis of the Dietary Reference Intakes (DRI) values and compared between the two groups. To further investigate the link between specific dietary nutrient intakes and EPL risk, adjusted binary logistic regression models were employed. The mean age of the participants was 28.5years, and their mean BMI was 24.20kg/m2. The dietary intake of carbohydrates, dietary fiber, monounsaturated fatty acids, omega-3 fatty acids, folate, vitamin C, potassium, iodine and total minerals were statistically higher in the control group (p < 0.05). Dietary vitamin D and cholesterol intake and the omega-6/omega-3 ratio were greater in the case group without statistical significance (p > 0.05). The control group presented significantly higher proportions of dietary supplement use, regular consumption between meals, and higher daily meal number (p < 0.05). Adjusted binary logistic regression analysis revealed negative correlations between total dietary fiber intake (continuous and Q3/Q4) and EPL risk in all models, even after adjusting for all potential confounders (p < 0.05). There was no statistically difference regarding nutrition knowledge level between two groups (p > 0.05). This study contributes to the literature by showing the protective role of maternal nutritional status in the first trimester against EPL risk.

This study aimed to compare patient satisfaction and oral health impact between individuals receiving complete dentures made by digital methods and those utilizing conventional techniques. In this randomized crossover clinical trial, 23 patients aged 40 and older with completely edentulous arches were enrolled at three treatment centers. Each participant received two sets of complete dentures: one set created using conventional methods (selective pressure impression) and the other through digital techniques (mucostatic digital impression). The order of denture placement was randomized, with each set used for four weeks. A trained specialist administered treatments, alongside research tools, including a general information questionnaire, a denture satisfaction survey, and the OHIP-14 interview tool. Statistical analysis was conducted using the Mann-Whitney U Test. Participants with digital dentures reported significantly higher satisfaction regarding treatment duration, comfort, confidence, chewing ability, aesthetics, and overall satisfaction compared to those with conventional dentures. There were no significant differences in satisfaction concerning speech and pronunciation. Overall, the oral health impact on quality of life was similar between denture types, but participants indicated improved quality of life while using dentures compared to being edentulous. Patients with digital dentures exhibited greater satisfaction across various domains compared to those with conventional dentures, despite similar satisfaction levels in speech and pronunciation. The impact on quality of life was comparable between both types, as measured by the OHIP-14.

Introduction &amp; Purpose: Open research data offer large potential for reuse, but also present complex challenges such as ownership, confidentiality, and data misuse which is especially important in human movement analysis. Although numerous datasets exist (Olugbade et al., 2023), insufficient metadata and poor compliance with the FAIR-principles (findable, accessible, interoperable, reusable) (Wilkinson et al., 2016) hinder effective data reuse. Hence, we aimed to develop guidelines for publishing data from human movement laboratories that can be adapted to similar contexts to promote FAIR data sharing. Methods: The guidelines were developed and refined in an iterative approach involving numerous movement laboratories. Initially, a survey was conducted among Swiss movement laboratories to assess current practices in open data sharing. A workshop was then held to refine key elements of the guidelines. Based on these inputs, a draft of the guidelines was developed, refined multiple times, validated, and published (Haas et al., 2024). Results: Choosing an appropriate license and repository is an essential step in data sharing as licenses are irrevocable and determine data use. Researchers should consider requirements from funders, institutions, and repositories. The FAIR principles and practical considerations such as file size limits, license terms, and data security can guide decisions. To enable other researchers to comprehend and make use of the deposited dataset, providing metadata is key. Metadata includes general information (e.g. data format, license) and specific information about the dataset, variables, analysis procedures, and used hard- and software. Discussion: Data itself should at least include basic statistical measures (minimum, maximum, mean, standard deviation) of all reported outcomes. Ideally, individual participant data should be made publicly available. However, this is only possible for anonymized data and encoded data when informed consent for reuse is obtained. In general, anonymizing data is recommended to support data sharing while ensuring compliance with legal and ethical standards. When reusing data, researchers must verify its quality through thorough checks. Conclusion: Data sharing should be considered early during project planning to ensure all necessary data is collected and ethical and legal requirements for publishing data are met. To remain effective and compliant, these guidelines need to be regularly updated and reviewed by the community.

Introduction Digital literacy has become a core competency for nursing professionals, enabling them to adapt to modern healthcare environments and engage effectively with emerging technologies. It is closely linked to innovative behavior, which is essential for problem solving and advancing nursing practice. Despite its importance, limited research has examined differences in digital literacy among undergraduate nursing students and how these differences influence innovation. Methods A cross-sectional study was conducted using a convenience sample of 450 undergraduate nursing students from four universities in Anhui Province, China. Participants completed a general information questionnaire, the Undergraduate Digital Literacy Scale, and the Innovative Behavior Scale. Latent profile analysis (LPA) was employed to classify students into distinct digital literacy profiles, while logistic regression and one-way ANOVA were used to explore factors influencing profile membership and the relationship between digital literacy and innovative behavior. Results Three latent profiles were identified: a “Low Digital Literacy” group (34.1%), a “Moderate Digital Literacy” group (15.9%), and a “High Digital Literacy” group (50.0%). Significant differences were observed across profiles in relation to gender, age, academic year, and frequency of artificial intelligence (AI) use in the past 6 months. Importantly, students with higher digital literacy consistently exhibited stronger innovative behavior ( p &amp;lt; 0.05), underscoring the role of digital competence in fostering creativity and adaptability. Conclusion Digital literacy among undergraduate nursing students is heterogeneous and shaped by demographic and experiential factors. Targeted educational interventions tailored to distinct literacy profiles are needed to bridge gaps, promote equity, and strengthen innovation. By integrating AI and advanced digital tools into nursing curricula, educators can enhance students’ competencies and better prepare them to thrive in an increasingly digital and intelligent healthcare landscape.

The study aimed to address the principles of circularity and sustainable development in the construction sector in the context of post-war reconstruction. General information on the classification of rubble was collected by analysing analytical reports, laws and regulatory and planning documents. The method of generalisation and systematisation was used to study the existing approaches to forming a comprehensive assessment of the efficiency of rubble processing technologies. Statistical data on the volume of destruction were processed using statistical analysis and data mining. The technical and technological analysis was used to assess the technical feasibility of sorting, crushing and further processing of construction materials. The analysis determined that as of 01.05.2024, a total of 4073 multi-apartment buildings in administrative districts in Kharkiv were destroyed. In the Saltivskyi administrative district, located in the eastern part of Kharkiv, 865 residential units were destroyed, while in the Kyivskyi district in the north-east of the city, 823 were destroyed. The study analysed the destruction in the Kharkiv region, the social and infrastructural burden in the Lviv region, and the specific environmental and transit conditions in the Zakarpattia region. The total direct economic damage caused to Ukraine since the beginning of the full-scale invasion has amounted to more than 155 billion USD. The massive destruction resulted in significant volumes of construction waste, which poses a substantial environmental threat and needs to be addressed immediately. An analysis of information from open sources and the media showed that the application of an integrated approach to the management of rubble based on the principles of the circular economy not only minimised the environmental impact of massive infrastructure destruction but also contributed to the efficient use of secondary resources in the process of restoring the affected areas. The practical significance of the study is determined by the possibility of applying the results obtained to develop effective strategies for managing construction waste in the context of post-war reconstruction, in particular through the introduction of systems for sorting, recycling and reuse of secondary materials at the national and regional levels

Knee osteoarthritis (KOA) is a clinical disease with a high incidence rate. Early identification and treatment of KOA are of great significance. This study aims to establish a predictive model using the movement-evoked pain (MEP) test for the early diagnosis of KOA. From May to December 2018, we conducted a cross-sectional survey among 3374 residents from 12 communities in Hangzhou City, Zhejiang Province. Data collection included general demographic information, the MEP test and treatment history. The data set was randomly divided into training set and validation set at a ratio of 7:3 by computer randomization. We analyzed the prevalence of KOA based on imaging and determined the influencing factors using logistic regression. Based on these factors, we constructed a nomogram and conducted validation. Among the 6748 knees analyzed, 78.4% were diagnosed with KOA based on imaging (KL grade ≥ 2). From 13 initial variables, we identified 9 independent predictors for the nomogram: age, exercise habits, pain during squatting, stair climbing, and housework, maximum pain, and history of oral NSAIDs, physical therapy, or intra-articular injections. A nomogram was developed based on these variables. The Area Under the Curve of the training set and validation set in the model were 0.889 (95% CI: 0.878-0.902) and 0.878 (95% CI: 0.859-0.898), respectively. The Brier score of the calibration curve was 0.127 and 0.131, respectively. The decision curve showed that it could increase the net clinical benefit within the risk threshold range of 20-80%. The MEP test enables imaging-independent KOA risk stratification, offering a feasible decision-support tool for primary care.

Debunking interventions to tackle misconceptions related to scientific issues have gained momentum, especially in the context of health care. In this randomized controlled experiment, we assessed the effectiveness of tailored (i.e., contrarian information addressing participants' specific motives with an affirmation of their psychological profile) and non-tailored (i.e., general contrarian information regardless of participants' psychological profile) debunking interventions in a sample of 167 Peruvian participants with positive attitudes toward egg cleanse, a popular local alternative medicine treatment. Our debunking interventions did not significantly correct attitudinal variables related to egg cleanse, such as belief in effectiveness, future use, and preference over conventional medicine. However, exploratory analyses showed significant reductions in endorsement of usage reasons within both the tailored debunk (d = 0.50) and non-tailored debunk (d = 0.62) groups. Moreover, a comparison between the two debunking groups indicated that participants who received a tailored debunk were more satisfied with the interaction with the physician than those who received a non-tailored debunk (d = 0.73). These results suggest that debunking interventions on misinformed health beliefs could have an impact also in the Peruvian cultural context and for alternative medicine, even though more direct attitudinal variables are particularly resistant to change. Strengths and weaknesses of tailored and non-tailored approaches to health misinformation, as well as future research pathways to shed light on the impact and pitfalls of debunking interventions, are discussed.

Peripherally Inserted Central Catheters (PICCs) are widely utilized in tumor patients due to their lower risk of complications, extended indwelling duration, reduced local tissue trauma, and overall cost-effectiveness. Based on the Health Action Process Approach (HAPA) theory, this study aims to explore the current status and influencing factors of kinesiophobia in tumor patients with PICCs. The study provides reference for clarifying the mechanism of kinesiophobia and developing nursing intervention plans. Through convenience sampling, 162 tumor patients who underwent PICC maintenance in three hospitals in Jiangsu Province from December 4th, 2023, to December 31st, 2024 were selected. The patient general information questionnaire, Tampa scale of kinesiophobia, medical coping modes questionnaire, exercise self-efficacy scale, risk perception questionnaire, outcome expectation scale, exercise intention scale, and social support rating scale were used for evaluation. Tumor patients carrying PICC had a kinesiophobia score of 20.11 ± 6.94 points, and 42.59% of tumor patients with PICC had kinesiophobia. The results of multiple linear regression showed that the duration of catheter placement(t = -3.506,P = 0.001), pain(t = 2.652,P = 0.009), exercise self-efficacy(t = -3.891,P < 0.001), and risk perception(t = 3.157,P = 0.002) are the main influencing factors of kinesiophobia in tumor patients with PICC. The findings underscore a significant clinical concern regarding kinesiophobia among tumor patients with PICC. It is essential for nursing staff to implement systematic assessments and tailored interventions aimed at mitigating kinesiophobia. Addressing this issue can contribute to reducing associated adverse reactions and improving patient mobility and overall quality of life.

Objective This study aims to assess the current level of electronic health literacy (eHL) among individuals diagnosed with colorectal cancer (CRC) and to identify associated factors that may inform the development of targeted interventions to support patient-centered health management. Methods A cross-sectional study was conducted involving 258 individuals with CRC, recruited using a convenience sampling method from a Class A tertiary hospital in Jiangsu Province, China. Data were collected using a general information questionnaire, the Chinese version of the eHealth Literacy Scale (eHEALS), the Multidimensional Scale of Perceived Social Support (MSPSS), the General Self-Efficacy Scale (GSES), and the European Quality of Life Five-Dimensions Questionnaire (EQ-5D). Univariate analyses and multiple linear regression were conducted to explore factors associated with eHL. Results The mean eHEALS score was 19.71 ± 8.97, indicating a generally low level of eHL among participants. Pearson correlation analysis demonstrated significant positive correlations between eHL and scores on the GSES, MSPSS, and EQ-5D ( p &amp;lt; 0.01). Multiple stepwise linear regression identified higher educational attainment, unmarried status, cohabitation with friends, presence of two or more chronic comorbidities, GSES scores, and EQ-5D scores as significant predictors of eHL ( R 2 = 0.658, F = 59.78, p &amp;lt; 0.05). Conclusion eHL remains suboptimal among individuals with CRC in China. Interventions should focus on populations at elevated risk of low eHL, with an emphasis on enhancing self-efficacy and improving health-related quality of life to facilitate more effective engagement with electronic health resources and improve clinical outcomes.

To investigate the clinical characteristics and imaging features of patients with spontaneous pneumomediastinum (SPM) and conduct a literature review to provide reference strategies for the diagnosis and treatment of the affected population. A retrospective analysis was conducted on patients diagnosed with SPM via chest computed tomography (CT) at our Hospital from January 2022 to December 2023. General information, clinical manifestations, and imaging findings were collected and analyzed. Relevant domestic and international literature was reviewed, and a comparative analysis was performed. A total of 40 patients were included in this study. Acute retrosternal pain was the most common symptom (45.0%), followed by varying degrees of dyspnea, shortness of breath, and chest tightness (25.0%), persistent coughing (17.5%), and discomfort or pain in the neck and throat (5%). The Macklin effect was observed in 38 patients, characterized by varying degrees of gas accumulation around the mediastinum near the pulmonary hilum. After three days of treatment, the symptoms resolved, and follow-up chest CT scans indicated absorption of mediastinal gas. Patients showed improvement and were discharged. The clinical manifestations of SPM are complex and diverse, making it prone to clinical misdiagnosis or delayed diagnosis, which may hinder timely treatment. Chest CT is instrumental in the accurate diagnosis of mild mediastinal emphysema. A comprehensive evaluation, incorporating patient complaints and clinical symptoms with chest CT findings, is essential for accurate diagnosis.

Prediction errors arising from contextual violations play a fundamental role in learning and memory, yet their effects remain controversial. While some research suggests prediction errors enhance memory for incongruent information, other evidence shows that schema-congruent events are better remembered. This study investigates how contextual congruency during encoding affects both recognition memory and retrieval of fine-grained perceptual details. Using object-scene pairings, we examined whether predictions based on memory schemas differentially influence the encoding of congruent versus incongruent information. The Mnemonic Similarity Task (MST) was adapted to incorporate naturalistic scene contexts. Participants viewed indoor scenes with contextually congruent or incongruent objects during encoding, then classified single objects as "old" (previously encountered at the encoding phase), "similar" (objects perceptually similar to previously encountered), or "new". Memory was assessed using the Corrected Recognition score (REC) for recognition accuracy, the Lure Discrimination Index (LDI) for fine-grained perceptual detail retrieval and discrimination, and the Rate of Correct Scores (RCS) for processing efficiency. Contextually congruent objects yielded significantly higher recognition accuracy and processing efficiency compared to incongruent objects. However, no congruency advantage was found for the retrieval of fine-grained perceptual details, with equivalent performance across conditions. These findings suggest that predictions based on memory schemas enhance encoding and retrieval of general item information, facilitating recognition and reducing cognitive demands. In contrast, encoding of fine-grained perceptual details appears unaffected by contextual congruency. These differential effects between recognition and retrieval of perceptual details offer important insights into how predictions influence distinct aspects of memory encoding.

Effectiveness and acceptance of tailored web-based psychoeducation for adolescents with major depression.

To explore the level of patient activation (PA) and its subgroups among postoperative breast cancer patients, and to analyze the differences and influencing factors across these subgroups. A cross-sectional study was conducted from May to December 2024 using convenience sampling. A total of 230 postoperative breast cancer patients from a tertiary hospital in China completed questionnaires including general information, the Patient Activation Measure, the Posttraumatic Growth Inventory, the Social Impact Scale (for stigma), and the Perceived Social Support Scale. Latent profile analysis was used to identify PA subgroups. Differences among subgroups were analyzed using ANOVA, Kruskal-Wallis, or chi-square tests, followed by multinomial logistic regression to determine influencing factors. The average PA score was 51.0 ± 11.5, indicating that patients recognize their important role in disease management but lack the confidence and knowledge to take action. Three PA subgroups were identified: high PA-relatively proactive type (30.4%), moderate PA-knowledge deficient type (46.1%), and low PA-passive dependent type (23.5%). Protective factors for higher PA included urban residence, being employed, higher posttraumatic growth, and monthly family income ≥ 3000 yuan (all P < 0.05). Obstructive factors included not undergoing breast-conserving surgery and higher perceived stigma (both P < 0.05). The PA score of postoperative breast cancer patients is classified at the second level, revealing three distinct categories with clear classification characteristics. Clinicians can identify patients exhibiting varying PA traits based on readily available demographic and disease-related data in clinical practice. This enables them to implement targeted interventions tailored to the specific characteristics and influencing factors of each group, ultimately enhancing PA levels.

To explore the relationship between the expression of cystatin C (CysC), tissue inhibitor of metalloproteinases-1 (TIMP-1), and secret fuzzed-related protein 5 (SFRP-5) in peripheral blood and cardiac remodeling and prognosis in chronic heart failure (CHF). It recruited 180 CHF patients and 60 healthy volunteers for comparison. Patients were divided into grade IV, III, and II groups based on cardiac function grading. Blood levels of N-terminal pro B-type natriuretic peptide (NT proBNP), CysC, chromogranin A (CgA), and echocardiography were analyzed. Treatment effects on cardiac function and quality of life were assessed using Minnesota Living with Heart Failure Questionnaire scale. Correlation between CysC, TIMP-1, SFRP-5 levels, and cardiac function was analyzed. No significant difference in general information among patients in each group. Patients with CHF had higher levels of CysC, CgA, and SFRP-5 compared to controls. NT proBNP, CysC, CgA, and SFRP-5 levels increased with worsening cardiac function. Left ventricular parameters worsened with increasing cardiac function level. Minnesota Living with Heart Failure Questionnaire score and levels of CgA, CysC, and SFRP-5 were positively correlated. CgA, CysC, and SFRP-5 levels were negatively correlated with left ventricular ejection fraction but positively correlated with NT proBNP and left ventricular mass index. Serum CgA and CysC levels in patients with CHF are correlated with cardiac function grade and ventricular remodeling, and SFRP-5 is one of the potential biomarkers of CHF.

This study assessed the accuracy and repeatability of the orthodontics-related information generated by Chat Generative Pre-trained Transformer (ChatGPT, model GPT-4o, 18July 2024, OpenAI, San Francisco, CA, USA) and evaluated its usefulness for patient education by comparing artificial intelligence (AI)-generated responses to questions that patients frequently search for with responses from two orthodontic specialists. In January and February 2025, 30 descriptive questions (15 on basic orthodontics and 15 on clinically advanced orthodontics) on nondecision, informational content in patient education were assessed, including a"briefly summarize within 500 characters" condition. Accuracy was defined as aresponse match between ChatGPT and the orthodontist, repeatability was the consistency of ChatGPT output over two iterations. Evaluations used a5-point Likert scale for accuracy and a5-point Global Quality Score (GQS) for repeatability. Data were analyzed using R, Wilcoxon signed-rank test and the Mann-WhitneyU test. Repeated responses from ChatGPT showed high repeatability with consistent overall accuracy. For basic orthodontics questions, accuracy increased slightly from 4.27 ± 1.03 to 4.53 ± 0.83 (p = 0.203). For clinically advanced orthodontics questions, accuracy remained stable (first: 3.67 ± 1.05, second: 3.73 ± 0.46, p = 0.850). In terms of repeatability and quality assessed by GQS, basic orthodontic questions scored moderately (first: 3.13 ± 0.83, second: 3.27 ± 0.70, p = 0.580), whereas clinically advanced orthodontics questions received higher GQS scores (first: 4.20 ± 0.77, second: 3.80 ± 0.56, p = 0.095), indicating potential applicability in patient education contexts. The accuracy and repeatability of ChatGPT's responses varied by question type: basic questions were more accurate, while clinically advanced orthodontic questions resulted in higher repeatability and quality. As these findings are limited to patient education and general information delivery, ChatGPT should not be considered areplacement for professional orthodontic expertise.

Objectives Occupational stress in nursing is a critical issue that can have significant implications for both workforce stability and personal health. This study aimed to identify subgroups of occupational stress among Chinese female clinical nurses using latent profile analysis, compare sociodemographic differences across these subgroups, and examine their associations with premenstrual syndrome (PMS). Methods A cross-sectional study was conducted among female nurses in tertiary hospitals in Huai’an City, Jiangsu Province, China, from November to December 2023. We recruited participants via convenience sampling, and 400 valid questionnaires were collected. Data were collected using a researcher-developed general information questionnaire, the standardized Chinese Nurses Stressor Scale (35 items), and the Premenstrual Syndrome Scale. Latent profile analysis (LPA) was performed with Mplus 8.0 to identify occupational stress subtypes. Sociodemographic predictors of these subtypes were explored using chi-square tests and multivariate logistic regression in SPSS 25.0. The association between stress subtypes and PMS symptoms was assessed using ANOVA. A p -value of &amp;lt; 0.05 was considered statistically significant for all analyses. Results Three clinical female nurse occupational stress subtypes were identified: overall low-stress (38.3%, n = 153), moderate stress–slight overload care (38.5%, n = 154), and high stress–overload nursing and career development challenge (23.2%, n = 93). Age, years of work experience, and monthly night shifts were key influencing factors. The results revealed a statistically significant difference in PMS scores across the stress groups ( p &amp;lt; 0.001). Specifically, nurses in the high stress–overload nursing and career development challenge group faced a significantly higher risk for PMS, whereas those in the overall low-stress group exhibited the fewest related symptoms. Conclusion This study identified significant heterogeneity in occupational stress among clinical female nurses, categorized into three distinct subtypes differing in stress levels and demographic characteristics. These findings highlight the importance of considering individual differences when developing interventions to address occupational stress. The study advocates for the implementation of intervention strategies targeting different types of stress in nursing education and organizational reform to better support nurses in fulfilling their responsibilities.

Background Magnesium is an important mineral that plays a role in many biochemical reactions in the body. Since it plays a role in many mechanisms of the body, it is thought that it may also have effects on stress and headaches. Methods The study was conducted with the participation of a total of 150 volunteer academic and administrative staff aged between 19 and 65. Participants were evaluated through general information, anthropometric measurements, Headache Impact Test-6 (HIT-6) and Perceived Stress Level Scale-10 (PSS-10), 3-day food consumption record and frequency of consumption of magnesium-rich foods questionnaire. Results The mean age of the participants was 31 ± 6.283 years for men and 28.55 ± 5.294 years for women. The Headache Impact Test-6 score was higher in the group with inadequate magnesium intake ( p &amp;lt; 0.05). Although the Perceived Stress Level Scale-10 score was also higher in the group with inadequate magnesium intake, the result was not significant ( p &amp;gt; 0.05). A negative correlation was found between dietary magnesium and HIT-6 and PSS-10 scores ( r = −0.183, r = −0.197, respectively; p &amp;lt; 0.05). A positive correlation was also found between the scales ( r = 0.456; p &amp;lt; 0.01). Conclusion These findings suggest that lower dietary magnesium intake is associated with higher headache impact and perceived stress in academic and administrative staff.

Objective: To understand the influence of characteristic factors of elderly care institutions on the level of self-awareness of the elderly with chronic diseases. Methods: A total of 428 elderly people with chronic diseases in elderly care institutions in Tangshan City were interviewed with the general information questionnaire, the characteristic factors questionnaire of elderly care institutions, and the Chinese version of the self-awareness scale. Results: The total score of the elderly with chronic diseases was 57.65 ± 15.09. Multiple linear regression showed that the influencing factors of the elderly with chronic diseases were household registration, income status, economic source, physical pain status, room number, family visit frequency, activity frequency, and nursing skills (P &lt; 0.05). Conclusion: The general level of self-awareness of the elderly with chronic diseases in the elderly care institutions in Tangshan is average, and there is great room for improvement. The nursing staff in institutions should pay attention to the autonomy of the elderly with chronic diseases, improve their level of self-awareness.

Recently, concerns about people's health and the environment have led to an increased tendency to consume organic and functional foods that contain health-beneficial compounds and protect the ecosystem. This research was conducted to examine the relationship between sociodemographic characteristics, health awareness, and obsession with healthy eating, as well as consumers' preferences for organic and functional foods. A total of 1022 volunteers aged 19-65 years participated in the study. General information, demographics, health information, anthropometric measurements, an organic and functional nutrition questionnaire, the Orthorexia-15 Scale (ORTO-15), and the Health Awareness Scale were applied to the participants. A total of 59.9% of the individuals were male, 60.7% were married, and 71.8% were university graduates. A slight majority of the individuals (55.5%) had a healthy body weight. The organic and functional food consumption scores of women were significantly higher than those of men (P = 0.005, P = 0.046, respectively). The organic food consumption score and health awareness score of individuals aged 31 years and above were significantly higher than those of individuals aged 19-30 years (P = 0.002, P < 0.001, respectively). Participants aged 19-30 years had higher functional food consumption than those aged 31 years or older, single participants had higher functional food consumption than married participants, and university graduates had higher functional food consumption than primary school graduates. In addition, there was correlation between health awareness and orthorexia nervosa (ON) (r = -0.229, P < 0.001), organic food consumption and ON (r = -0.080, P = 0.011), organic food consumption and health awareness (r = 0.153, P < 0.001). There was correlation between functional food consumption and ON (r = -0.125, P < 0.001), functional food consumption and health awareness (r = 0.124, P < 0.001). Health-oriented attitudes of individuals are effective in their dietary behaviours. However, it was determined that orthorexic tendencies predicted both organic and functional food consumption, while health awareness was a significant predictor only of organic food consumption. Policies aimed at improving health awareness are expected to increase demand for organic and functional foods. Comprehensive and extended-duration studies are necessary to determine the factors that influence the consumption of these foods. © 2026 Society of Chemical Industry.
