Abstract Background Although middle-aged and elderly users are the main group targeted by health maintenance-oriented WeChat official accounts (HM-WOAs), few studies have explored the relationship of these accounts and their users. Exploring the factors that influence the continuous adoption of WOAs is helpful to strengthen the health education of middle-aged and elderly individuals. Objective We developed a new theoretical model and explored the factors that influence middle-aged and elderly individuals' continuous usage intention for HM-WOA. Performance expectancy mediated the effects of the model in explaining continuous usage intention and introduced health literacy into the model. Methods We established a hybrid theoretical model on the basis of the unified theory of acceptance and use of technology 2 model (UTAUT2), the health belief model (BHM), protection motivation theory (PMT), and health literacy. We collected valid responses from 396 middle-aged and elderly users aged ≥ 45 years in China. To verify our hypotheses, we analyzed the data using structural equation modeling. Results Performance expectancy (β = 0.383, P < 0.001), hedonic motivation (β = 0.502, P < 0.001), social influence (β = 0.134, P = 0.049), and threat appraisal (β = 0.136, P < 0.001) positively influenced middle-aged and elderly users' continuous usage intention. Perceived health threat (β =  − 0.065, P = 0.053) did not have a significant effect on continuous usage intention. Both threat appraisal (β = 0.579, P < 0.001) and health literacy (β = 0.579, P < 0.001) positively affected performance expectancy. Threat appraisal indirectly affected continuous usage intention through performance expectancy mediation. Conclusions Our new theoretical model is useful for understanding middle-aged and elderly users' continuous usage intention for HM-WOA. Performance expectancy plays a mediation role between threat appraisal and continuous usage intention, and health literacy positively affects performance expectancy.

BACKGROUND Health maintenance-oriented WeChat official accounts, an important channel for obtaining health information, have attracted considerable attention from the social science community. However, studies on middle-aged and elderly users'sustainable usage intention of health maintenance-oriented WeChat official accounts are lacking. Increasing the sustainable usage intention of such accounts can strengthen public health education. OBJECTIVE Develop a theoretical model and explore influence factors of middle-aged and elderly users’ sustainable usage intention of health maintenance-oriented WeChat official accounts. METHODS A hybrid theoretical model was established on the basis of unified theory of acceptance and use of technology 2, health belief model, protection motivation theory, and health literacy. IBM SPSS version 24.0 was used to description statistic. IBM SPSS AMOS version 21.0 was used to construct and verify the research model. Three hundred ninety-six valid responses were collected by means of online and offline surveys. RESULTS Performance expectancy (ß=0.383, p<0.001), hedonic motivation (ß=0.502, p<0.001), social influence (ß=0.134, p=0.049), and threat appraisal (ß=0.136, p<0.001) positively influence the sustainable usage intention. Perceived health threat (ß=-0.065, p=0.053) don't has an significant effect on middle-aged and elderly users’ sustainable usage intention of official health maintenance-oriented WeChat accounts. Both threat appraisal (ß=0.579, p<0.001) and health literacy (ß=0.579, p<0.001) positively affect performance expectancy. Threat appraisal indirectly affects sustainable usage intention through performance expectancy mediation. CONCLUSIONS This study focused on middle-aged and elderly users and explored determinants of their sustainable usage intention of official health maintenance-oriented WeChat accounts. Performance expectancy, threat appraisal, social influence, and hedonic motivation are positive determinants. In addition, performance expectancy plays a mediation role between threat appraisal and continued use intention.

Hospitals have begun to provide their own apps to improve the efficiency of hospital services. This study investigated the factors influencing the adoption of medical apps by hospital patients by using a theoretical model that combines the extended unified theory of acceptance and use of technology (UTAUT) with the concept of e-health literacy and personal innovativeness (PI). Data were obtained from responses to a paper-based self-reported questionnaire issued to patients at a hospital in Taoyuan, Taiwan. Of the 650 distributed questionnaires, we received 629 completed questionnaires, yielding a response rate of 96.8%. The responses to the completed questionnaires were analyzed using structural equation modeling (SEM). Partial least squares regression was used for model and hypothesis testing. The data were analyzed using an SEM approach to test ten hypotheses; significant support was observed for five of these hypotheses. The results indicated that habit, performance expectancy, facilitating conditions, and PI had significant positive effects on the usage intention (UI) of individuals, thereby confirming that e-health literacy moderates the association between performance expectancy and UI. This research contributes to the current understanding of adoption of hospital medical apps by patients. The findings are expected to assist hospitals in deciding whether to consider medical apps when investing in information technology.

The five viscera score (FVS) is a diagnostic scale for traditional Chinese medicine (TCM). The purposes of current study are to elucidate the characteristics of FVS obtained from middle-aged to elderly individuals and to investigate the validity of FVS using biological medical data of middle-aged and elderly individuals. Structural equation modeling (SEM) was used to conduct assessments between FVS and medical data. Eighty men and 99 women participated in this study, whose mean ages (SD) were 58 ± 7 years in both genders showing no significant difference. FVS of women was significantly higher than that of men in the spleen of the 50s (P=0.019) and liver of the 60s age group (P=0.030). By SEM, the following biomedical factors were found to influence viscera: gender, diastolic blood pressure, and HDL-C for the liver; GLU, GOT, andγ-GTP for the spleen; age, BMI, and HCRP for the lungs; and HbA1c and creatinine clearance for the kidneys. These results provide objective evidence that FVS can be used for TCM diagnosis in middle-aged and elderly individuals.

Abstract Opioid overdose risk is particularly high in immigrant communities partly due to limited English proficiency (Guarino et al., 2015). Previous studies reported that social determinants of health (SDH) have been associated with risk for opioid overdose (Dasgupta et al., 2018). The current study examines the association between SDH and literacy of opioid overdose risk among the immigrant population living in a rural area. Specifically, we examine the association in various age groups including young adults (aged 20 to 34), middle-aged (aged 35 to 49), and older adults (ages 50 to 75). Data were drawn from a sample of Korean American immigrants residing in rural Alabama (N=225). The participants administered the Brief Opioid Knowledge (BOOK) Questionnaire (Dunn et al., 2016). Multiple regression analyses were conducted for three age groups to identify predictors of opioid literacy. Overall, older adults had lower levels of opioid literacy relative to their younger counterparts. Among young adults, low English proficiency, more chronic conditions, and greater depressive symptoms were significant predictors of limited opioid literacy. For the middle-aged adults, lower levels of health literacy and more pain symptoms were associated with limited opioid literacy. Among older adults, women, those with higher English proficiency, and lower health literacy had lower levels of opioid literacy. The findings demonstrated a greater vulnerability of older immigrants to limited opioid literacy. Different predictors based on SDH of limited opioid literacy across age groups have implications for tailored health promotion strategies to reduce opioid overdose risk.

The Impact

Due to the outbreak of COVID-19, many people have to accept remote working. However, as COVID-19 has been effectively controlled in China, remote office services provided by enterprise social networks (ESNs) is no longer a necessary choice of users. There has not yet been any referential research for ESN enterprises concerning how to encourage users willing to use ESNs continuously. Therefore, the purpose of this research is to identify the critical factors of ESN continuous usage intention to make up the research gap of ESN continuous usage intention and to help enterprises address the issue of sustained growth. This research combines elements of the task technology fit (TTF) model and D&M information systems success (ISS) model, explaining the continuous usage intention of ESN users. The empirical analysis results are based on the sample data of 668 Chinese respondents with experience in ESNs use and analyzed using structural equation modeling (SEM). Results show that task technology fit, performance expectancy and the satisfaction degree have a significant influence on continuous usage intention of ESNs. The research findings can provide the theoretical basis for sustained development and follow-up research of the ESN industry.

Abstract Background The floating population in China consists primarily of internal immigrants and represents a typical health vulnerable group. Poor health literacy has recently become an obstacle in the accessibility and utilization of health services for the vulnerable population, leading to adverse health outcomes. This study aimed to examine whether health literacy affected health outcomes in China’s floating population and whether health service utilization had a mediating effect between health literacy and health outcomes. Method The current study utilized a cross-sectional stratified, multistage, proportional to scale (PPS) study in Zhejiang Province, China, in November and December 2019. In total, 657 valid self-reported questionnaires were recovered and used for data collection. Questionnaires included questions regarding sociodemographic characteristics, health literacy, health outcomes, and health service utilization. Confirmatory factor analysis was used to test questionnaire validity; descriptive statistics were used to understand the demographic characteristics of the floating population; and structural equation modeling was used to determine whether health service utilization mediated health literacy and health outcomes. Results We report positive correlations between health literacy, health service utilization, and health outcomes. Mediation analysis demonstrated that health service utilization had partial mediating effects between health literacy and health outcomes. In the relationship between health literacy and health outcomes, the indirect effects of health service utilization accounted for 6.6–8.7% of the total effects. Conclusion Complete health literacy, through health care literacy and health promotion literacy, affects the mobile population’s initiative to use health services, which, in turn, affects health outcomes. Thus, improving the health literacy of the floating population will help to improve health outcomes. Furthermore, health service providers should enhance the diversity of health service supply to ensure that the floating population has the external resources to improve personal health literacy.

This study investigated the factors that influence Ghanaian entrepreneurs to adopt e-commerce. Cross-sectional data was gathered from 520 entrepreneurs in the most populous and industrious regions in Ghana. The unified theory of acceptance and use of technology (UTAUT) was employed to effectively understand the unexplored phenomenon of e-commerce adoption among Ghanaian entrepreneurs. Partial Least Square-Structural Equation Modeling (PLS-SEM) was used to test the hypothesized relationships. The findings indicate that performance expectancy, effort expectancy, and social influence (SI) positively and significantly influenced the behavioral intention (BI) to adopt e-commerce. Facilitating conditions (FC) and BI had a significant positive relationship with the adoption of e-commerce.
