This article explores the disease-associated stigma attached to the SARS victims in the post-SARS era of Hong Kong. I argue that the SARS-associated stigma did not decrease over time. Based on the ethnographic data obtained from 16 months of participant observation in a SARS victims' self-help group and semistructured interviews, I argue that the SARS-associated stigma was maintained, revived, and reconstructed by the biomedical encounters, government institutions, and public perception. I also provide new insight on how the SARS-associated stigma could create problems for public health development in Hong Kong. As communicable diseases will be a continuing threat for the human society, understanding how the disease-associated stigma affects the outcomes of epidemic control measures will be crucial in developing a more responsive public health policy as well as medical follow-up and social support service to the diseased social groups of future epidemic outbreaks.

Background: COVID-19 vaccination is recommended for older adults by the World Health Organization. However, by July 15, 2021, only 26% of individuals over 60 years old in Hong Kong had received a first dose of the vaccine. The health belief model and the theory of planned behavior have been used to understand the determinants for COVID-19 vaccination in past literature. However, vaccination determinants can be complex and involve social and cultural factors that cannot be explained by micro-individual factors alone; hence, the health belief model and the theory of planned behavior cannot provide a complete understanding of vaccine hesitancy. Few studies on the barriers to, hesitancy toward, and motivations for COVID-19 vaccination among older Chinese adults have been performed. The aim of this study is to fill this gap by conducting a comprehensive analysis of this subject using the critical medical anthropology framework, extending the health belief model and the theory of planned behavior in understanding vaccination determinants among the older adult population. Methods: Between November 2020 and February 2021, 31 adults (24 women and 7 men) over the age of 65 took part in semi-structured, one-on-one interviews. The data we gathered were then analyzed through a phenomenological approach. Results: Two major themes in the data were examined: barriers to vaccination and motivations for vaccination. The participants’ perceptions of and hesitancy toward vaccination demonstrated a confluence of factors at the individual (trust, confidence, and social support networks), microsocial (stigma toward health care workers), intermediate-social (government), and macrosocial (cultural stereotypes, civic and collective responsibility, and economic considerations) levels according to the critical medical anthropology framework. Conclusions: The decision to receive a COVID-19 vaccination is a complex consideration for older adults of low socioeconomic status in Hong Kong. Using the critical medical anthropology framework, the decision-making experience is a reflection of the interaction of factors at different layers of social levels. The findings of this study extend the health belief model and the theory of planned behavior regarding the understanding of vaccination perceptions and relevant behaviors in an older adult population.

(1) Background: Environment is an independent factor that affects one’s quality of life (QoL), where studies suggest that health behaviours also affect one’s quality of life. The purpose of the present study was to examine the association between environmental conditions and QoL and how individual health behaviours affect this association. (2) Methods: Participants aged 20 or above were recruited from 11 tertiary planning units in the central part of Kowloon. These tertiary planning units were selected as they represented the overall living environment in Hong Kong, with a mix of the poorer urban areas alongside relatively affluent districts. A mediation analysis was implemented using multiple linear regressions to examine the effects of environmental conditions on QoL. (3) Results: Of the 607 eligible participants included for analysis, 390 were female and 217 were male, with a mean age of 47.4 years. Living within 500 m of a green space area had benefits on the physical aspect of QoL and physical activity but no effect on the psychological aspect of QoL. Moderate satisfaction with public spaces affected QoL positively. In contrast, less satisfaction with public spaces affected QoL negatively in both physical and psychological aspects through the mediating effect of stress. Poor environmental quality affected all domains of QoL negatively through the mediating effects of increased stress and poor sleep. (4) Conclusions: Environment is an important factor that affects individuals’ overall well-being. The interaction between environmental conditions and individual variables, especially perceived stress and sleep, is extremely important when assessing its impact on QoL. The findings of this study support the importance of individual stress and sleep in mediating the relationship between the environment and QoL for health. Further studies should be conducted to include objective measurements, such as those of cortisol levels for stress and physical fitness tests.

Background: HPV vaccine is a prophylactic vaccine to prevent HPV infections. Recommended by the World Health Organization, this vaccine is clinically proven to be one of the most effective preventive measures against the prevalence of cervical cancer and other HPV-associated cancers and chronic genital conditions. However, its uptake rate among women in Hong Kong is insignificant—only approximately 2.9% adolescent girls and 9.7% female university students received HPV vaccination in 2014. With the notion of Critical Medical Anthropology, we aimed to identify if different influential factors, ranging from individual, societal, and cultural, are involved in the decision-making process of whether to receive HPV vaccination.Methods: We adopted a qualitative approach and conducted in-depth individual semistructured interviews with 40 women in Hong Kong between May and August 2017.Results: We noted that the following factors intertwined to influence the decision-making process: perceptions of HPV and HPV vaccine; perceived worthiness of HPV vaccines, which was in turn influenced by vaccine cost, marriage plans, and experiences of sexual activities; history of experiencing gynecological conditions, stigma associated with HPV vaccination, acquisition of information on HPV vaccines, distrust on HPV vaccines, and absence of preventive care in the healthcare practice.Conclusions: HPV vaccination is promoted in a manner that is “feminized” and “moralized” under the patriarchal value system, further imposing the burden of disease on women, and leading to health inequality of women in pursuing the vaccination as a preventive health behaviour as a result. We believe that this ultimately results in an incomplete understanding of HPV, consequently influencing the decision-making process. The “mixed-economy” medical system adopting capitalist logic also molds a weak doctor–patient relationship, leading to distrust in private practice medical system, which affects the accessibility of information regarding HPV vaccination for participants to make the decision.

Health inequality creates conditions for the transmission of infectious diseases, and existing health disparities can contribute to unequal burdens of morbidity and mortality. In Hong Kong, low socioeconomic districts were the epicentres of third‐wave outbreak of COVID‐19 in July and August 2020, suggesting that people from low socioeconomic class are vulnerable groups. Socially disadvantaged people are relatively more vulnerable to the physical, mental, and social impacts of infectious diseases. To achieve more effective infection control, the social determinants of health and existing health inequalities should be identified, and understanding the experiences of socially disadvantaged groups in the COVID‐19 outbreak will be beneficial to health authorities in formulating a responsive infection control policy targeting the needs of the socially disadvantaged. This article investigates the experiences of economically disadvantaged groups during the COVID‐19 outbreak and examines how they were further disadvantaged in the outbreak by delineating how health inequality intersected with social inequality. In‐depth, semistructured interviews were conducted from February to April 2020 with 35 participants from the poverty class in Hong Kong. The high prices of surgical face masks and disinfecting products as well as the economic impacts induced by COVID‐19‐related social distancing policies imposed severe economic burden on the participants. In addition to economic and housing deprivation, social inequality was closely associated with health inequality, which made the participants more vulnerable to infection. Social inequality is associated with and can worsen health inequality. Here, the participants, who were of low socioeconomic status were more disadvantaged in health and in the attainment of social resources such as employment, education, face masks, disinfection products and right to use public facilities, during the COVID‐19 outbreak. All these elements may have interrelated effects and in turn limit accessibility to healthcare and lead to less positive health outcomes and consequently to health inequality.

Objectives This study aimed to (1) determine the knowledge level of young adults towards blood donation, and (2) to understand their donor identity and the meanings of blood donation to them. Design A questionnaire-based cross-sectional survey. Setting and participants Undergraduate students of a university in Hong Kong recruited by convenience sampling, at public facilities in campus such as student canteens and the Campus Blood Donor Centre of the university. Outcome measures The questionnaire which consisted of three parts was used for data collection. Part 1 collected sociodemographic information and items associated with blood donation; part 2 related to knowledge on blood donation and part 3 focused on blood donor identity. Univariate and multivariate logistic regression analyses were conducted to determine the OR and identify the predictors for blood donation. Results Among the 542 respondents, 274 were non-blood donors and 268 were blood donors. Blood donors generally have a better knowledge towards blood donation than non-blood donors. The results of univariate analyses indicated that being a female (OR=1.99, p<0.001), aged 22 years or above (OR=234, p<0.001), studying at year 4 or 5 (OR=2.12, p=0.003), studying health-related programmes (OR=1.96, p<0.001), being registered as an organ donor (OR=6.59, p<0.001), had prior experience of receiving blood (OR=7.60, p<0.001) or prior experience of being refused for blood donation (OR=5.14, p<0.001) were significantly associated with being a blood donor. Having prior experience of receiving blood was the strongest predictor for being a blood donor, followed by being registered as an organ donor, after controlling for all other factors in the logistic regression model. Conclusions The findings are consistent with self-determination theory, which hypothesises that people are more likely to abide with blood donation behaviours that are internally rather than externally motivated.
