Organizational health literacy (OHL) is essential for reducing adverse outcomes associated with limited health literacy, including medication errors, incre

This study aimed to examine the association between the cardiometabolic index (CMI) and intrinsic capacity (IC) and its domains among older adults in China using data from the China Health and Retirement Longitudinal Study (CHARLS). Using data from 7,058 participants aged 60-80 years from the 2011-2020 waves of CHARLS, this cross-sectional study examined the association between CMI and IC and its domains. The total IC score was derived from five standardized domains: cognitive, psychological, vitality, locomotion, and sensory. Multiple linear regression models were used to assess the associations between CMI and IC_total as well as its domains. Stratified analyses by sex, age group, and chronic disease status were conducted to examine the robustness of the findings. In addition, an exploratory mediation analysis was performed to assess whether the observed association between CMI and IC was statistically consistent with an indirect association through vitality. In the crude model, higher CMI was significantly associated with lower IC_total scores (β = -0.049, P < 0.001). In the age- and sex-adjusted model, CMI was positively associated with the cognitive domain (β = 0.084, P < 0.001) and the psychological domain (β = 0.036, P = 0.002), and inversely associated with vitality (β = -0.128, P < 0.001), while no significant association was observed with IC_total. After further adjustment for available sociodemographic and health-related covariates, higher CMI was significantly associated with lower IC_total (β = -0.060, 95% CI: -0.084 to -0.037, P < 0.001) and lower vitality (β = -0.144, 95% CI: -0.167 to -0.121, P < 0.001), whereas the associations with the cognitive, psychological, locomotion, and sensory domains were no longer statistically significant. Mediation analysis suggested that the observed association between CMI and IC was statistically consistent with an indirect association through vitality; however, this finding should be interpreted cautiously given the cross-sectional design. Among older Chinese adults, higher CMI was independently associated with lower overall intrinsic capacity and lower vitality after adjustment for available covariates. The positive associations with the cognitive and psychological domains observed in simpler models were attenuated after fuller adjustment, suggesting that these associations may be partly explained by confounding. Overall, vitality appears to be the IC domain most consistently associated with cardiometabolic burden in later life.

Objective: This study aims to quantitatively and comprehensively evaluate the association between digital addiction (DA) and subjective well-being (SWB) in adolescents. Methods: A comprehensive search was conducted across multiple electronic databases, including PubMed, Web of Science, Embase, EBSCO, Cochrane Library, CNKI, Wanfang, and VIP, to identify studies examining the correlation between DA and SWB in adolescents. Subgroup and sensitivity analyses were conducted to explore sources of heterogeneity and assess the robustness of the pooled estimates. Publication bias was evaluated using funnel plots, Begg’s and Egger’s tests, the PET–PEESE approach, and the trim-and-fill method. Results: This study was registered in PROSPERO (registration number: CRD420251014128). The meta-analysis included 17 studies comprising a total of 30,915 adolescents. A random-effects model was employed for the pooled analysis, which revealed a significant negative correlation between DA and SWB (Fisher’s Z = –0.30, 95% CI [−0.34, −0.27]). A high level of heterogeneity was observed ( I ² = 86.6%). Subgroup analyses indicated that the association between DA and SWB was moderated by region and study quality, but not by sample size, publication year, DA subtype, or participant age. Conclusion: DA is negatively correlated with SWB. Therefore, it is essential to establish a comprehensive intervention framework that integrates family, school, societal, and individual efforts. This can be accomplished through transforming parenting practices within families, enhancing digital health literacy and psychological screening in schools, strengthening online supervision and accountability in society, and fostering self-directed learning skills among adolescents, ultimately improving their SWB.

To quantitatively analyze China’s fertility-friendly policies issued from 2016 to 2025, examine their structural characteristics and evolution, and provide evidence for policy optimization. A two-dimensional framework of “policy tools–policy objectives” was constructed. Content analysis, word frequency analysis, and semantic network analysis were applied to 46 central-level fertility-friendly policy texts. The number of fertility-friendly policies showed an overall upward trend with clear phased features. The policy system demonstrated service orientation, system coordination, and multi-level advancement. Environmental, supply, and demand policy tools accounted for 40.65%, 40.29%, and 19.06%, respectively, indicating an imbalanced distribution of policy tools at the central-government level. In terms of policy obectives, service-friendly, cultural and social-friendly, and interpersonal-friendly goals accounted for 73.14%, 24.32%, and 2.54%, respectively, revealing an uneven goal hierarchy. The alignment between policy tools and policy objectives was insufficient, and system coordination remained weak. China’s fertility-friendly policy system has shifted from initial exploration to systematic development, forming a relatively diversified but still structurally unbalanced policy structure. Future policies should increase direct financial subsidies, expand paid parental leave, and strengthen employer responsibility-sharing mechanisms, while enhancing coordination between service provision and interpersonal support systems and promoting the construction of a multi-level fertility support network involving government, society, communities, and families to improve overall policy effectiveness.

Background: The frailty syndrome is among the most prevalent geriatric syndromes, while social media has become a pivotal place for retrieving health information. Objective: The objectives of this study are to investigate the quality of frailty-related videos on major Chinese social media platforms and examine the correlation of the quality with user engagement. Methods: Collect the videos about frailty from TikTok, Bilibili, and Xiaohongshu. Document the general characteristics, uploader information, and content features of each video. Evaluate the quality of each video with the Journal of the American Medical Association (JAMA) benchmark criteria, the Global Quality Score (GQS), modified DISCERN (mDISCERN), and the Patient Education Materials Assessment Tool for Audiovisual Materials (PEMAT-A/V). Results: We examined 126 videos in current study. Overall, quality was not promising with a mean JAMA score of 1.1 (SD=0.8), GQS of 2.8 (SD=1.0), mDISCERN of 3.0 (SD=0.8), PEMAT-understandability of 76.5% (SD=15.6%), and PEMAT-actionability of 49.7% (SD=40.2%). Among the platforms, Bilibili had the highest quality videos, and Xiaohongshu had the lowest videos quality. Videos produced by organizations, non-profit groups, medical-related personnel, certified authors, expert monologue, and question & answer is better. The correlation between video quality and user engagement metrics was negligible. Conclusions: The video quality on social media platforms remains inadequate, offering limited utility to users. Frequently, the viewers cannot precisely determine if content from videos is valid or not. First, uploaders need to optimize video quality and second the oversight of platforms should be strengthened to improve public health literacy and raise awareness.

The latest evidence on health literacy in China revealed that only 8% of individuals aged 65–69 years, a segment of the geriatric population, possess adequate health literacy levels, indicating a low level in China. Studies have demonstrated that improving the organizational health literacy of healthcare institutions is a crucial approach to addressing low health literacy among older patients. To explore the obstacles hindering the advancement of organizational health literacy in healthcare institutions in meeting the needs of older patients. A mixed-methods approach was employed to investigate both the status and barriers to the establishment of organizational health literacy within two healthcare institutions. Participants included older individuals aged over 60, clinical staff, and managerial personnel from these two health institutions. This research utilized the social-ecological model as its theoretical foundation and utilized a mixed-methods approach to examine the current status and challenges in developing organizational health literacy within healthcare institutions. Initially, a survey using a questionnaire (n = 178) was conducted among older patients to evaluate the establishment of organizational health literacy from their perspective. Following this, interviews (n = 22) were carried out with administrators, clinical personnel, and elderly patients to identify the barriers hindering the development of organizational health literacy within healthcare institutions. Quantitative research indicates that health institutions have been less accommodating to the requirements of older patients, with health information dissemination and communication emerging as the weakest areas. Qualitative investigations revealed three key influencing factors: patient-related factors, including physiological and cognitive decline, as well as low educational attainment among older patients; organizational factors, including inadequate clinical staff numbers, deficient long-term systematic training, and a digital divide resulting from health institutions’ digital advancements; and policy-related factors indicating a lack of regulations governing the establishment of organizational health literacy within healthcare institutions. The two most vulnerable aspects of OHL in medical institutions regarding the needs of older patients are health information and communication. The factors influencing the construction of OHL in medical institutions are multifaceted, encompassing micro, meso, and macro levels. At the macro level, it is essential for medical institutions to enhance leadership awareness of OHL and to incorporate its development into institutional strategic plans. At the meso-level, medical institutions should be made to optimize the medical environment for elderly patients and to prioritize health literacy training for medical staff. At the micro level, attention must be given to the characteristics and needs of elderly patients. Ultimately, by implementing a comprehensive construction of intervention strategies, the response ability of medical institutions to the needs of elderly patients can be enhanced.
