Exposure to light at night (LAN) and risk of overweight/obesity, hypertension, and diabetes: a systematic review and meta-analysis.

Current studies have presented conflicting findings regarding the associations between light at night (LAN) exposure and the risk of overweight/obesity, hypertension, and diabetes. Our study systematically summarized the evidence of the association between LAN exposure and the risk of overweight/obesity, hypertension, and diabetes. We searched five databases (PubMed, Web of Science, Embase, Scopus, and Cochrane) for observational studies published up to 1 August 2023. The pooled odds ratio (ORs) and 95% confidence intervals (CIs) were estimated by random-effects models for the association. Eighteen studies were included in the meta-analysis. Compared with the group with the lowest level of LAN, the group with the highest level of LAN is associated with an increased risk of overweight/obesity (pooled OR = 1.19, 95%CI: 1.13-1.26), hypertension (pooled OR: 1.86, 95% CI:1.28-2.72), and diabetes (pooled OR = 1.21, 95%CI: 1.07-1.31). Our meta-analysis demonstrated LAN exposure is associated with increased risk of overweight/obesity, hypertension, and diabetes.

Barriers and facilitators to technology acceptance of socially assistive robots in older adults - A qualitative study based on the capability, opportunity, and motivation behavior model (COM-B) and stakeholder perspectives.

This study aimed to identify barriers and facilitators to older adults' acceptance of socially assistive robots from a stakeholder perspective. We enlisted 36 distinct stakeholders, including older adult, nurses, retirement home managers, and employees from robotics companies. Data collection was conducted through semi-structured interviews. The research findings were mapped onto the Capability, Opportunity, Motivation-Behavior (COM-B) model. We obtained a total of 14 facilitators and barriers. (1) Capability: High technological familiarity (Facilitator); insufficient technical experience and low level of education (Barriers). (2) Motivation: Strong interest in new things, perceived convenience usefulness, and emotional support (Facilitators); concerns about technical reliability, perceived lack of ease of use, inability to establish emotional connection, and low level of need (Barriers). (3) Opportunity: Insufficient policy support and economic capacity, robotics technical problems (Barriers). Collaborative efforts among stakeholders are vital for fostering an environment conducive to socially assistive robot adoption, maximizing its potential to improve older adults' well-being.

Death anxiety, sense of meaning in life, and willingness to body donation among nursing students in anatomy course: An explanatory sequential mixed study.

BACKGROUND: Anatomy education is a fundamental part of clinical nursing, but anatomy courses may lead to a range of psychological changes, such as death anxiety and sense of meaning in life. Such experiences and changes may influence student's willingness to donate their body. There is insufficient evidence on whether anatomy courses bring about these changes, and the reasons behind experiences are unclear. Focusing on these changes is essential to improve anatomy education in nursing and to promote the mental health of students in the nursing field. OBJECTIVES: To explore changes and underlying reasons for death anxiety, sense of meaning in life, and the willingness to donate a body before and after anatomy courses. DESIGN: An explanatory sequential explanatory mixed-methods study. PARTICIPANTS: A total of 60 students completed quantitative surveys and 16 students from the sub-samples of the quantitative stage were included in the qualitative interviews. All students were from a comprehensive university in Changsha, Hunan Province, China. METHODS: Data were collected from September 2022 to April 2023, including two rounds of questionnaire surveys and one interview. The questionnaires included sociodemographic data, the Death Anxiety Scale (CT-DAS), the Meaning of Life Scale (MLQ), and a body donation willingness question. Interviews were conducted based on the research objectives. The statistical methods included descriptive statistics, z-tests, and thematic analysis. RESULTS: Quantitative results showed a decrease in emotional dimension of death anxiety (z = -2.534, P < 0.05) and an increase in body donation willingness (z = -3.183, P < 0.05). Qualitative analysis revealed cognitive experience and value assessment may relate to the changes. Based on the two themes, the reduction of death anxiety in emotional dimension can be further attributed to four factors: demystification, instrumentalization, desensitization, and respect and gratitude towards donors. The increase in willingness to donate bodies can be further attributed to two aspects: increase in knowledge of body donation and the affirmation of the value of donation. CONCLUSION: The study found that students experience a decrease in death anxiety in the emotional dimension and an increased inclination to donate their bodies after anatomy courses, which may be related to cognitive experience and value assessment. Future nursing anatomy education could delve deeper into these two perspectives and support students to positively cope with death anxiety and rethink body donation through enriching death education activities such as donor memorial ceremonies. These results provide a basis for designing anatomy courses and improving the psychological well-being and professional competence of nursing students.

Technology Acceptance of Socially Assistive Robots Among Older Adults and the Factors Influencing It: A Meta-Analysis.

The purpose of this study was to deeply understand older adults' acceptance of socially assistive robots and their influencing factors and to compare the strength of the correlation between each influencing factor variable and the acceptance. The literature search was performed in five databases from their inception to January 17, 2023. The meta-analysis was performed using Review Manager 5.4 and Stata 16.0 software. Thirteen papers were included in this study. The mean value of acceptability after using the inverse variance method was 3.68. Education level is strongly related to technology acceptance; perceived ease of use, perceived usefulness, technology experience, technology attitude, perceived hedonism, and convenience are moderately related; anxiety is only weakly related.

The relationship between body donation and attitudes toward death and altruism in Changsha City in China.

In recent years, China has been facing a shortage of cadavers for teaching medical students. A better comprehension of the attitudes and factors influencing the general public's opinion toward body donation would be invaluable for planning and implementing body donation programs. Although altruistic attitude and attitudes toward death have received considerable attention in recent years globally, they have been largely understudied in China. Herein, the potential relationship between attitudes toward altruism and death, and willingness toward whole-body donation in a sample of university students in Changsha City in China were analyzed. A multi-stage sampling method was adopted to recruit 478 Chinese college students from two universities: the Medical College of Hunan Normal University (n = 272) and the College of Civil engineering of Hunan University (n = 206). The study participants were assessed by a sociodemographic questionnaire, the Death Attitude Profile-Revised (DAP-R-C) questionnaire, and the altruism scale. Moreover, Chinese University students demonstrated moderate willingness to donate their bodies. The mean score of the willingness of study participants to donate their bodies was 3.138 ± 0.933 (5-point Likert scale). Acceptance toward death, gender, and type of university were positive factors, whereas fear of death negatively affected willingness toward body donation. Regression analysis showed that factors, including gender (ß = 0.237), type of university (ß = 0.193), natural acceptance (ß = 0.177), and fear of death (ß = -0.160) influenced willingness toward body donation. Overall, the present study provides hitherto undocumented evidence on factors influencing willingness toward body donation among Chinese university students, which can assist in designing public awareness programs for encouraging body donation.
