A systematic review of the impact of psychosocial factors on immunity: Implications for enhancing BCG response against tuberculosis.

Background: Tuberculosis (TB) remains an urgent global public health priority, causing 1.5 million deaths worldwide in 2018. There is evidence that psychosocial factors modulate immune function; however, how this may influence TB risk or BCG vaccine response, and whether this pathway can be modified through social protection, has not been investigated. This paper aims to: a) systematically review evidence of how psychosocial factors influence the expression of biomarkers of immunity, and b) apply this general evidence to propose plausible TB-specific pathways for future study. Methods: Papers reporting on the impact of psychosocial stressors on immune biomarkers in relation to infectious disease risk were identified through a search of the databases MEDLINE, PsycINFO, Global Health and PsycEXTRA alongside reference list and citation searching of key papers. Data extraction and critical appraisal were carried out using a standardised form. The findings were tabulated and synthesised narratively by infectious disease category, and used to propose plausible mechanisms for how psychosocial exposures might influence immune outcomes relevant to TB and BCG response. Results: 27,026 citations were identified, of which 51 met the inclusion criteria. The literature provides evidence of a relationship between psychosocial factors and immune biomarkers. While the direction and strength of associations is heterogenous, some overarching patterns emerged: adverse psychosocial factors (e.g. stress) were generally associated with compromised vaccine response and higher antibody titres to herpesviruses, and vice versa for positive psychosocial factors (e.g. social support). Conclusions: The evidence identifies pathways linking psychosocial factors and immune response: co-viral infection and immune suppression, both of which are potentially relevant to TB and BCG response. However, the heterogeneity in the strength and nature of the impact of psychosocial factors on immune function, and lack of research on the implications of this relationship for TB, underscore the need for TB-specific research

College Students’ Perceptions of and Behaviors Regarding Facebook© Advertising: An Exploratory Study

The recent boom of social media has given marketers new opportunities to advertise to a targeted demographic -- specifically, tech-savvy young adults and students. This study examines the perceptions of and attitudes toward advertisements on one of the most popular social networking sites today, Facebook©. Results of an exploratory study show that while most college students are active Facebook© users, they are unlikely to click on Facebook© advertising or engage in purchase behaviors

Stress, health and quality of life of female migrant domestic workers in Singapore: a cross-sectional study.

Abstract Background: There is a global increase in migrant workers. In Singapore, there are over 230,000 migrant domestic workers (MDWs). Female MDWs may experience high levels of stress and social isolation, which may negatively impact on their health and quality of life. There have also been documented cases of abuse and exploitation. However, there is a lack of empirical research with this population. This study aimed to investigate factors impacting on the health and quality of life of female MDWs in Singapore, including socio-demographic and job related characteristics, stress, social isolation, and working management style. Methods: A cross-sectional survey was carried out with 182 female MDWs in Singapore. The survey examined health and quality of life (WHOQoL-Bréf), social connectedness (the Friendship Scale), and preferred and experienced working management style (the Theory X and Theory Y Questionnaire). Descriptive analyses were carried out in addition to ANOVA, t-tests, and chi-square tests, followed by a multivariate analysis using linear regression. Results: Participants were found to have good overall quality of life and satisfaction with health. Age and working experience were found to be significantly (p < 0.05) associated with overall quality of life and three domains (psychological, social, and environmental health). Agreement between experienced and preferred working management style was also found to be associated with higher quality of life scores (with the exception of the social relationships domain). Though women reported relatively good overall quality of life, more than half of participants reported feeling stressed. In addition, nearly 20% of participants reported being isolated or very isolated. Stress was identified to be associated with isolation. In the multivariate analysis, stress was found to contribute to worse quality of life in all domains except social relationships, after adjusting for confounders. Social connectedness was positively associated with all domains of quality of life, and agreement of working management style was positively associated with physical health, psychological health and environmental quality of life. Conclusions: The findings serve as an evidence-base pointing to the need for policies aimed at decreasing stress and social isolation among female MDWs in order to improve their health and quality of life

Challenges in researching migration status, health and health service use: an intersectional analysis of a South London community.

OBJECTIVES: This study aimed to investigate the associations between migration status and health-related outcomes and to examine whether and how the effect of migration status changes when it is disaggregated by length of residence, first language, reason for migration and combined with ethnicity. DESIGN: A total of 1698 adults were interviewed from 1076 randomly selected households in two South London boroughs. We described the socio-demographic and socio-economic differences between migrants and non-migrants and compared the prevalence of health-related outcomes by migration status, length of residence, first language, reason for migration and migration status within ethnic groups. Unadjusted models and models adjusted for socio-demographic and socio-economic indicators are presented. RESULTS: Migrants were disadvantaged in terms of socio-economic status but few differences were found between migrant and non-migrants regarding health or health service use indicators; migration status was associated with decreased hazardous alcohol use, functional limitations due to poor mental health and not being registered with a general practitioner. Important differences emerged when migration status was disaggregated by length of residence in the UK, first language, reason for migration and intersected with ethnicity. The association between migration status and functional limitations due to poor mental health was only seen in White migrants, migrants whose first language was not English and migrants who had moved to the UK for work or a better life or for asylum or political reasons. There was no association between migration status and self-rated health overall, but Black African migrants had decreased odds for reporting poor health compared to their non-migrant counterparts [odds ratio = 0.15 (0.05-0.48), p < 0.01]. CONCLUSIONS: Disaggregating migration status by length of residence, first language and reason for migration as well as intersecting it with ethnicity leads to better understanding of the effect migration status has on health and health service use

Perceived stressors and coping mechanisms of female migrant domestic workers in Singapore.

INTRODUCTION: Worldwide, there are between 50-67 million migrant domestic workers, the majority of whom are women. In many countries, provisions are not in place to protect female migrant domestic workers. These women may be at risk of occupational and social stressors, including exploitation and abuse, which may negatively impact on their quality of life, including psychological health. Research examining the occupational, social, and psychological needs of FMDWs from a public health perspective is critical to guide the development of policies which ensure wellbeing, prevent abuse, and align with international priorities to improve population health. Though there have been a number of high-profile incidents of exploitation and abuse, there has been limited research on the stressors experienced by these communities, their perceived impact, or coping mechanisms. MATERIALS AND METHODS: Thematic analysis was used to analyse qualitative free-text written responses collected as part of a cross-sectional survey on the relationship between social and occupational stressors and the health and quality of life of FMDWs in Singapore. Responses correspond to open-ended questions in the qualitative component of the survey examining three domains: causes of stress, coping strategies, and what people can do to help with stress. RESULTS: Responses from 182 FMDWs were analysed. Key themes were identified around causes of stress (including 'work and agency', 'the pervasiveness of financial need', and 'family and obligation'), coping strategies, and social support. Each theme describes key factors which contribute to the occupational and social stressors experienced and reported by FMDWs. DISCUSSION: This research highlights the stressors FMDWs in Singapore experience, as well as key coping mechanisms. There is a clear need for policies which facilitate FMDWs' ability to utilise these coping resources, and which protect against coercive or exploitative employment conditions. Strategies are also needed to monitor and evaluate policies intended to protect FMDWs, and to strengthen the implementation of global frameworks targeted at improving workplace conditions and workers' rights
