International survey for assessing COVID-19’s impact on fear and health: study protocol
Introduction COVID-19, caused by the SARS-CoV-2, has been one of the most highly contagious and rapidly spreading virus outbreak. The pandemic not only has catastrophic impacts on physical health and economy around the world, but also the psychological well-being of individuals, communities and society. The psychological and social impacts of the COVID-19 pandemic internationally have not been well described. There is a lack of international study assessing health-related impacts of the COVID-19 pandemic, especially on the degree to which individuals are fearful of the pandemic. Therefore, this study aims to (1) assess the health-related impact of the COVID-19 pandemic in community-dwelling individuals around the world; (2) determine the extent various communities are fearful of COVID-19 and (3) identify perceived needs of the population to prepare for potential future pandemics.
Methods and analysis This global study involves 30 countries. For each country, we target at least 500 subjects aged 18 years or above. The questionnaires will be available online and in local languages. The questionnaires include assessment of the health impacts of COVID-19, perceived importance of future preparation for the pandemic, fear, lifestyles, sociodemographics, COVID-19-related knowledge, e-health literacy, out-of-control scale and the Patient Health Questionnaire-4. Descriptive statistics will be used to describe participants’ characteristics, perceptions on the health-related impacts of COVID-19, fear, anxiety and depression, lifestyles, COVID-19 knowledge, e-health literacy and other measures. Univariable and multivariable regression models will be used to assess the associations of covariates on the outcomes.
Ethics and dissemination The study has been reviewed and approved by the local ethics committees in participating countries, where local ethics approval is needed. The results will be actively disseminated. This study aims to map an international perspective and comparison for future preparation in a pandemic
Mental health and health-related quality of life of Chinese college students who were the victims of dating violence
© 2016, Springer International Publishing Switzerland. Purpose: The aim of the study is to evaluate the mental health and health-related quality of life (HRQOL) of Chinese college students who were the victims of dating violence. Methods: Six hundred and fifty-two subjects were included in the data analysis. Subjects completed a structured questionnaire containing the Woman Abuse Screening tool, the Hospital Anxiety and Depression Scale, the 10-item version of the Perceived Stress Scale (PSS-10) and the World Health Organization Quality of Life-BREF Instrument (WHOQOL-BREF). Results: Analysis by independent t test suggested that victims of dating violence had more severe depressive, anxiety and stress symptoms and poorer HRQOL than non-victims. Multiple linear regression models found that more severe dating violence victimization was associated with more severe depressive, anxiety and stress symptoms. The mediation analysis found that after simultaneously controlling for the degree of depressive, anxiety and stress symptoms, the direct effect between dating violence severity and HRQOL, as measured by overall HRQOL and the global health, physical and environment domains of the WHOQOL-BREF, was statistically insignificant, supporting a full-mediation model. The relationship between dating violence severity and the social domain of HRQOL was partially mediated by the degree of depressive, anxiety and stress symptoms. Conclusion: Victims of dating violence had poorer mental health and HRQOL than non-victims. The study findings affirm the importance of assessing depressive, anxiety and stress symptoms in victims and the need to improve their depressive, anxiety and stress symptoms to diminish the negative effects of dating violence, which are apparent in their HRQOL.Link_to_subscribed_fulltex
Association Between Using Smartphone Dating Applications and Alcohol and Recreational Drug Use in Conjunction With Sexual Activities in College Students
© 2017 Taylor & Francis Group, LLC. Background: The association between using smartphone dating applications (apps) and substance use in conjunction with sexual activities was only examined in homosexual men. This association was poorly understood in heterosexual samples. Objective: To explore the association between using dating apps and alcohol, and use of recreational drug in conjunction with sexual activities in college students. Design: 666 students from four universities in Hong Kong were recruited in this cross-sectional study in the year 2015. Outcome measures included the use of dating apps, sexual history, and drug and alcohol use. Multivariable logistic regressions were employed. Results: The use of dating apps for more than 1 year was found to be associated with recreational drug use in conjunction with sexual activities (adjusted odds ratio: 7.23). Other risk factors of recreational drug use in conjunction with sexual activities included being bisexual/homosexual male, a smoker, and having one's first sexual intercourse at the age of less than 16 years. The use of dating apps was not a risk factor for alcohol consumption in conjunction with sexual activities. Risk factors for alcohol consumption in conjunction with sexual activities included being older, having monthly income more than HKD5,000, and a smoker. Furthermore, risk factors for alcohol consumption in conjunction with the last sexual activity included currently being in a dating relationship, a smoker, and having sex with a casual partner. Conclusions: Using dating apps is an emerging risk factor of drug misuse. Interventions for practising safe sex and preventing drug use should be targeted at dating app users.Link_to_subscribed_fulltex
The association between smartphone dating applications and college students' casual sex encounters and condom use
© 2016 Elsevier B.V. Objective: This study aims to explore the association between using smartphone dating applications (apps) and having unprotected sex with a casual sex partner. Study design: This is a cross-sectional study. Students were recruited from four university campuses in Hong Kong by convenience sampling. Main outcome measures: Subjects completed a structured questionnaire asking about the use of dating apps, sexual history and socio-demographic information. Multiple logistic regressions were used to explore the association between using dating apps and having unprotected sex with a casual sex partner. Results: Six hundred and sixty-six subjects were included in the analysis. Users of dating apps were more likely to have had unprotected sex with a casual sex partner the last time they engaged in sexual intercourse (aOR: 10.06). Using dating apps for more than 12 months was associated with having a casual sex partner in the last sexual intercourse (aOR: 3.21), as well as having unprotected sex with that casual partner (aOR: 13.56). Conclusion: We found a robust association between using dating apps and having unprotected sex with a casual sex partner, implying that using dating apps is an emerging sexual risk factor. We recommend that interventions promoting the safe use of dating apps should be implemented.Link_to_subscribed_fulltex
The safe use of dating applications among men who have sex with men:A study protocol for a randomised controlled trial to evaluate an interactive web-based intervention to reduce risky sexual behaviours
BACKGROUND: Notably, both international and local studies have found a high prevalence of sexually transmitted infections (STIs) and risky sexual behaviours, such as condomless anal sex, substance misuse in conjunction with sex ('chemsex') and group sex, among men who have sex with men (MSM) dating application (app) users. Although the use of dating apps is an emerging sexual risk factor, little effort has been expended on the promotion of safe sex and good sexual health among the users of those apps. Therefore, the aim of the proposed study is to develop and evaluate the effectiveness of an interactive web-based intervention in improving the sexual health of MSM dating app users in Hong Kong. METHODS: A two-armed randomised controlled trial will be conducted. Chinese MSM dating app users will be recruited and randomly allocated into either the intervention (n = 200) or control group (n = 200). Subjects in the intervention group will receive the web-based intervention containing interactive content that (1) encourages a positive attitude towards consistent condom use and HIV/STI testing and negative attitude towards chemsex and group sex; (2) positions condom use and regular HIV/STI testing as normative; and (3) targets improved perceived self-efficacy concerning condom use and negotiation and HIV/STI testing. The control group will receive only web-based information without sexual health components. Subjects in both groups will be evaluated at baseline and three and 6 months after baseline. The primary outcome will be the frequency of condomless anal sex in the past 3 months. DISCUSSION: The proposed study will aid development of culturally relevant health promotion programmes aimed at minimising the potential harm of dating app use and promoting the sexual health of MSM dating app users. The web-based intervention, if found successful, will have important clinical and policy implications, as it can be adopted by the government and non-governmental organisations targeting MSM. Moreover, the proposed intervention can reach many MSM at relatively low cost, and thus has the potential to check the burgeoning HIV/STI epidemic among MSM in Hong Kong in a cost-effective manner.

Analytic Eye Movement Patterns in Face Recognition are Associated with BetterPerformance and more Top-down Control of Visual Attention: an fMRI Study
Recent research has revealed two different eye movement pat-terns during face recognition: holistic and analytic. The pre-sent study investigated the neural correlates of these two pat-terns through functional magnetic resonance imaging (fMRI).A more holistic pattern was associated with more activation inthe face-selective perceptual areas, including the occipitalface area and fusiform face area. In contrast, participants us-ing a more analytic pattern demonstrated more activation inareas important for top-down control of visual attention, in-cluding the frontal eye field and intraparietal sulcus. In addi-tion, participants using the analytic patterns had better recog-nition performance than those showing holistic patterns. The-se results suggest that analytic eye movement patterns are as-sociated with more engagement of top-down control of visualattention, which may consequently enhance recognition per-formance
Personal wearable devices to measure heart rate variability: A framework of cloud platform for public health research
© 2017 Copyright is held by the owner/author(s). Background: Heart rate variability (HRV) refers to the variation in time interval between heart rates (RR-interval). Studies have demonstrated that emotional disorder is associated with lower HRV. Electrocardiography (ECG) is the conventional HRV measurement conducted by healthcare professionals. Wearable devices with HRV measurement function may be a convenient and low-cost alternative. This study aimed to evaluate the HRV results between a wearable device and ECG. Methods: Parents from disadvantaged families were recruited and requested to wear the wearable device, second generation of Microsoft Band (MS band), on their non-dominant hand and a 7-lead ECG simultaneously for 10 minutes. Mean RR-interval was used to measure the level of HRV; subject with mean RR-interval greater than 750ms was defined as normal. Sensitivity and specificity was used to quantify the consistence between the MS band and the ECG. Results: A total of 40 subjects were recruited. The mean RR-interval of ECG measurements ranged from 487.87 to 1076.5; 9 of them had abnormal RR-interval. The sensitivity and specificity of the MS band were 88.89% and 77.42% respectively. Conclusion: This study showed that wearable device was a reliable instrument for HRV measurement in static posture. Further investigations should look into the accuracy during motion.Link_to_subscribed_fulltex
