Background
As the coronavirus disease 2019 (COVID‐19) pandemic is sweeping across the globe, there is an urgent need to develop effective vaccines as the most powerful strategy to end the pandemic. ...This study aimed to examine how factors related to vaccine characteristics, their social normative influence and convenience of vaccination can affect the public's preference for the uptake of the COVID‐19 vaccine in China.
Methods
An online discrete choice experiment (DCE) survey was administered to a sample of China's general population. Participants were asked to make a series of hypothetical choices and estimate their preference for different attributes of the vaccine. A mixed logit regression model was used to analyse the DCE data. Willingness to pay for each attribute was also calculated.
Results
Data of 1236 participants who provided valid responses were included in the analysis. There was strong public preference for high effectiveness of the vaccine, followed by long protective duration, very few adverse events and being manufactured overseas. Price was the least important attribute affecting the public preference in selecting the COVID‐19 vaccine.
Conclusions
The strong public preferences detected in this study should be considered when developing COVID‐19 vaccination programme in China. The results provide useful information for policymakers to identify the individual and social values for a good vaccination strategy.
Patient or Public Contribution
The design of the experimental choices was fully based on interviews and focus group discussions participated by 26 Chinese people with diverse socio‐economic backgrounds. Without their participation, the study would not be possible.
•Refusal rate of nurses to influenza vaccine reduced during the pandemic.•A low acceptance level and high hesitancy level to COVID vaccination was observed.•A strong association between COVID-19 and ...influenza vaccine acceptance was found.•Major concern of nurses about the COVID-19 vaccine was its efficacy and safety.
Maintaining health of healthcare workers with vaccination is a major component of pandemic preparedness and acceptance of vaccinations is essential to its success. This study aimed to examine impact of the coronavirus disease 2019 (COVID-19) pandemic on change of influenza vaccination acceptance and identify factors associated with acceptance of potential COVID-19 vaccination.
A cross-sectional self-administered anonymous questionnaire survey was conducted among nurses in Hong Kong, China during 26 February and 31 March 2020. Their previous acceptance of influenza vaccination and intentions to accept influenza and COVID-19 vaccination were collected. Their relationship with work-related and other factors were examined using multiple multinomial logistic regressions.
Responses from 806 participants were retrieved. More nurses changed from vaccination refusal to hesitancy or acceptance than those changed from acceptance to vaccination hesitancy or refusal (15.5% vs 6.8% among all participants, P < 0.001). 40.0% participants intended to accept COVID-19 vaccination, and those in private sector (OR: 1.67, 95%CI: 1.11–2.51), with chronic conditions (OR: 1.83, 95%CI: 1.22–2.77), encountering with suspected or confirmed COVID-19 patients (OR: 1.63, 95%CI: 1.14–2.33), accepted influenza vaccination in 2019 (OR: 2.03, 95%CI: 1.47–2.81) had higher intentions to accept it. Reasons for refusal and hesitation for COVID-19 vaccination included “suspicion on efficacy, effectiveness and safety”, “believing it unnecessary”, and “no time to take it”.
With a low level of COVID-19 acceptance intentions and high proportion of hesitation in both influenza and COVID-19 vaccination, evidence-based planning are needed to improve the uptake of both vaccinations in advance of their implementation. Future studies are needed to explore reasons of change of influenza vaccination acceptance, look for actual behaviour patterns of COVID-19 vaccination acceptance and examine effectiveness of promotion strategies.
Infectious diseases, including COVID-19, are crucial public health issues and may lead to considerable fear among the general public and stigmatization of, and discrimination against, specific ...populations. This meta-analysis aimed to estimate the pooled prevalence of stigma in infectious disease epidemics. We systematically searched PubMed, PsycINFO, Embase, MEDLINE, Web of Science, and Cochrane databases since inception to June 08, 2021, and reported the prevalence of stigma towards people with infectious diseases including SARS, H1N1, MERS, Zika, Ebola, and COVID-19. A total of 50 eligible articles were included that contributed 51 estimates of prevalence in 92722 participants. The overall pooled prevalence of stigma across all populations was 34% 95% CI: 28-40%, including enacted stigma (36% 95% CI: 28-44%) and perceived stigma (31% 95% CI: 22-40%). The prevalence of stigma in patients, community population, and health care workers, was 38% 95% CI: 12- 65%, 36% 95% CI: 28-45%, and 30% 95% CI: 20-40%, respectively. The prevalence of stigma in participants from low- and middle-income countries was 37% 95% CI: 29-45%, which is higher than that from high-income countries (27% 95% CI: 18-36%) though this difference was not statistically significant. A similar trend of prevalence of stigma was also observed in individuals with lower education (47% 95% CI: 23-71%) compared to higher education level (33% 95% CI: 23-4%). These findings indicate that stigma is a significant public health concern, and effective and comprehensive interventions are needed to counteract the damaging effects of the infodemics during infectious disease epidemics, including COVID-19, and reduce infectious disease-related stigma.
Vaccine hesitancy is among the major threats to the effectiveness of vaccination programmes. This study aimed to report the trend in response to willingness to accept the COVID-19 vaccine between two ...waves of the local epidemic and examine differences among occupations. Two cross-sectional surveys were conducted online during the first wave (February) and third wave (August to September) of the local epidemic in 2020. Acceptance of the COVID-19 vaccine was measured along with personal protection behaviours and occupations. A total of 2047 participants provided valid responses. The willingness to accept the COVID-19 vaccine among the participants was lower in the third wave (34.8%) than the first wave (44.2%). There were more concerns over vaccine safety in the third wave. Clerical/service/sales workers were less likely to accept the vaccine (adjusted odds ratio: 0.62, 95% confidence interval: 0.43-0.91). A high-level compliance of facemask wearing was found, and more people maintained social distancing and used alcohol hand rub in the third wave. Decreasing willingness to accept the COVID-19 vaccine may be associated with increasing concerns about vaccine safety and growing compliance of personal protection behaviours. The rush of vaccine development with higher risks of safety issues may jeopardize the public's trust and lower uptake rates. Education and favourable policy should be provided to the general working population for the vaccination, especially for those who are not professional and are frequently exposed to crowds.
During the early phase of the coronavirus disease epidemic in Hong Kong, 1,715 survey respondents reported high levels of perceived risk, mild anxiety, and adoption of personal-hygiene, ...travel-avoidance, and social-distancing measures. Widely adopted individual precautionary measures, coupled with early government actions, might slow transmission early in the outbreak.
Oral melatonin is a potential alternative treatment for hypertension and nocturnal hypertension. However, high‐quality and relevant meta‐analyses are lacking. This meta‐analysis aimed to investigate ...whether oral melatonin supplementation reduces daytime/asleep blood pressure and cardiovascular risk, improves sleep quality, and is well‐tolerated compared with placebo. Relevant articles were searched in multiple databases, including MEDLINE, EMBASE, CINAHL Complete, and the Cochrane Library, from their inception to June 2021. The included studies were randomized controlled trials recruiting patients with hypertension, using oral melatonin as the sole intervention, and investigating its effect on blood pressure. The mean out‐of‐office (including 24‐h, daytime, and asleep) systolic and diastolic blood pressures, sleep quality, and side effects were compared between the melatonin and placebo arms using pairwise random‐effect meta‐analyses. A risk of bias assessment was performed using the Cochrane risk‐of‐bias tool. Four studies were included in the analysis and only one study was considered to have a low risk of bias. No study reported on cardiovascular risk or outcomes. Only controlled‐release melatonin (not an immediate‐release preparation) reduced asleep systolic blood pressure by 3.57 mm Hg (95% confidence interval: –7.88 to .73; I2 = 0%). It also reduced asleep and awake diastolic blood pressure, but these differences were not statistically significant. Melatonin improves sleep efficacy and total sleep time and is safe and well‐tolerated. Due to the limited number of high‐quality trials, the quality of evidence was low to very low. Therefore, adequately powered randomized controlled trials on melatonin are warranted.
According to the 2015 Quality of Death Index published by the Intelligence Unit of the Economist, Hong Kong is ranked 22nd in terms of quality of palliative care in the world, behind many other major ...developed countries in Asia, including Taiwan, Singapore, Japan, and South Korea. The objectives of the present study were to describe the knowledge, attitude, and preferences of the general Hong Kong adult population across different age groups regarding end-of-life (EOL) care decisions, place of care and death, as well as advance directive (AD).
This was a population-based cross-sectional survey conducted by telephone. A total of 1067 adults over 30 years old were contacted through residential telephone lines using a random sampling method and were interviewed. Information on sociodemographic factors, general health status, chronic diseases, knowledge, attitude and preferences of advance decisions, EOL care, and place of death were collected.
A total of 85.7% had not heard of AD, but 60.9% would prefer to make their own AD if legislated after explanation; and for those who did not prefer to have an AD, the predominant concern was the possible change of mind afterward. Adjusted logistic regression suggested that female participants were less willing to make an AD, whereas those with prior knowledge of do-not-attempt-cardiopulmonary-resuscitation significantly increased the chance of making an AD. In terms of life-sustaining treatments, a predominant 87.6% preferred to receive appropriate palliative care that gives comfort rather than to prolong life if being diagnosed to be terminally ill; 43% disagreed that doctors should generally try to keep patients alive for as long as possible; and 86.2% agreed that the patient's own wishes should determine what treatment he/she should receive. Adjusted logistic regression showed that palliative care was more preferred by age groups 50 years or above but was less preferred by those who did not care for their family members with chronic diseases. Regarding place of death, 31.2% of the participants would choose to die at home, and among those, 19.5% would still prefer to die at home even if they did not have sufficient support. Adjusted logistic regression showed a decreased trend for all older age groups from 40-49 years to 80+ years, as well as having poor self-rated health, to prefer to die at home. Being a female participant and having education level of tertiary or above, however, had higher preference for death at home.
This is the first population-representative survey of the general Hong Kong adult population on the knowledge, attitude, and preferences of AD, EOL care, and place of care/death. The main implication of this study was that preferences to have autonomy over own EOL care, to receive palliative care, and to die at home were greater than the actual practice currently, highlighting the service gaps for better EOL care in the future.
To investigate the effect of a modified mindfulness-based stress reduction (mMBSR) program on mental well-being and cognitive function of older adults.
Two hundred and fourty-six participants were ...randomly assigned to mMBSR (n = 120) group or waitlist control group which received mMBSR at 2-month (n = 123). Data collected at baseline, 2 and 4 months after recruitment.
mental well-being: Short Warwick-Edinburgh Mental Well-being Scale (SWEMWBS).
Five Facet Mindfulness Questionnaire Short Form, Montreal Cognitive Assessment (MOCA), Verbal Fluency Test (VFT), international shopping list test, self-compassion scale, peace of mind scale, geriatric depression scale (GDS), and Pittsburgh sleep quality index (PSQI). In modified-intention-to-treat analysis, paired t-test for within group comparison, and ANCOVA to compare group differences at 2-months with adjustment of baseline values.
Most participants were female (83.7%), living with others (67.0%), and married (50.7%). No significant difference of baseline characteristics except sleep quality. At 2 months, intervention group reported better mental well-being (0.9, 95%CI: 0.1-1.8, p = 0.025) and less depressive symptoms (-1.0; 95%CI: -1.7 to -0.3, p = 0.004). Within group at 2 months, intervention group had improvement in: mental well-being (SWEMWBS: 22.5-23.4, p = 0.011), cognitive function (MOCA: 24.6-25.8, p < 0.001; VFT: 38.7-42.1, p < 0.001), depressive symptoms (GDS: 4.1-3.1, p < 0.001), and sleep quality (PSQI: 8.3-6.7, p < 0.001). All these changes, except mental well-being, were sustained at 4 months.
Attrition rate was 14% and mindfulness intervention was found to be feasible and acceptable in older adults. Major limitation of the study was the absence of an active control group to control for non-specific effect.
Little is known about how multisystemic childhood exposures predict adult depression. This study aims to examine the effects of multisystemic childhood exposures on the onset and remission of adult ...depression.
Data were drawn from the China Health and Retirement Longitudinal Survey (CHARLS) (wave 1–4), which is a nationally representative longitudinal survey of people 45 years of age or older in China. Childhood family relationships (CFR), childhood peer friendships (CPF), and childhood neighborhood quality (CNQ) scores were recoded into binary (No = 0, Yes = 1) according to the first quantile value. Participants were divided into four groups based on the total number of poor childhood exposures (group 0–3). The generalized linear mixed model was used to test the longitudinal relationship between combined poor childhood exposures and adult depression.
Of the 4696 participants (55.1 % males), 22.5 % suffered from depression at baseline. The incidence of depression increased from group0 to group3 in four waves, reaching the peak in wave 2018 (incidence of group0 to group3: 14.1 %, 18.5 %, 22.8 %, 27.4 %, p < 0.001), with declining remission rates that reached its lowest in wave 2018 (50.8 %, 41.3 %, 34.3 %, 31.7 %, p < 0.001). The persistent depression rate increased from group0 to group3 (2.7 %, 5.0 %, 8.1 %, 13.0 %, p < 0.001). The risk of depression in group1 (AOR = 1.50, 95%CI: 1.27–1.77), group2 (AOR = 2.43, 95%CI: 2.01–2.94) and group3 (AOR = 4.24, 95%CI: 3.25–5.54) were significantly higher than that in group0.
Childhood histories were collected via self-reported questionnaires, and thus recall bias was inevitable.
Multisystem poor childhood exposures jointly increased the onset and persistence of adult depression, as well as reduced the remission rate of depression.
•Poor childhood exposures in family, friends and neighbors are positively correlated.•Multisystemic exposures predict high onset and persistence of adult depression.•Multisystemic exposures predict a lower remission rate of adult depression.
