Can platform use patterns be an indicator of HIV-related risk and sub-group heterogeneity among men who have sex with men in Singapore
Introduction Low-level HIV epidemic settings like Singapore face the challenge of reaching men at-risk who have less contact with programmes. We investigated patterns of meeting platform use by men seeking male sexual partners (MSM) as potential marker of risk to differentiate sub-groups for interventions. Methods Latent Class Analysis (LCA) was applied to a survey sample of MSM recruited from bars/clubs, saunas and a smartphone application, usin…
Prevalence, drivers and surveillance of antibiotic resistance and antibiotic use in rural China
This study aimed to characterise antibiotic prescribing and dispensing patterns in rural health facilities in China and determine the community prevalence of antibiotic resistance. We investigated patterns and drivers of antibiotic use for common respiratory and urinary tract infections (RTI/UTI) in community settings, examined relationships between presenting symptoms, clinical diagnosis and microbiological results in rural outpatient clinics, a…
Mental health and resilience after the covid-19 pandemic
Our study joins a body of work measuring the longitudinal effects of COVID-19 on population mental health and resilience. While, the magnitude of the effect related to resilience decline is small, our findings indicate that particular attention should be given to ongoing population surveillance, with the aim of maintaining good health and well-being
Seroprevalence of IgG antibodies against diphtheria antitoxin among migrant workers in Singapore, 2016–2019
The proportions having at least basic protection against diphtheria in migrant workers from five out of seven Asian countries (India, Indonesia, Malaysia, Myanmar and the Philippines) were higher than 85%, the threshold for diphtheria herd immunity. Seroprevalence surveys should be conducted periodically to assess the level of immunity against diphtheria and other vaccine preventable diseases in migrant worker population, so that appropriate inte…
Exploring theory-based behavioral interventions promoting Covid-19 prevention and healthcare-seeking for migrant worker men in Singapore
Overall, the findings showed that the conception of the Four Ss helped inform intervention strategies. Anchoring these towards optimal use of technology and harnessing of interpersonal communication for prevention and promotion of healthcare seeking in the planning of future Infectious Disease outbreaks in closed institutional settings is recommended
Individual, interpersonal, and situational factors influencing HIV and other STI risk perception among gay, bisexual, and other men who have sex with men
Gay, bisexual, and other men who have sex with men (GBMSM) are disproportionately affected by HIV and other sexually transmitted infections (STI). While levels of self-perceived risk of HIV or other STI acquisition has been well-established as a factor that is positively associated with HIV or other STI testing, less effort has been made to identify the processes through which GBMSM assess their perceived risk of HIV or other STI acquisition. We …
Clinics as spaces of costly disclosure
Gay, bisexual and queer men in Singapore are disproportionately represented in prevalent HIV infections, relative to the general population. While anticipated stigma has been found to be a barrier to HIV/STI testing among gay, bisexual and queer men, little effort has been made to contextualise such stigma within the broader sociocultural milieu. We conducted 35 in-depth interviews with a purposively recruited sample of men in Singapore with a fo…
Developing a Typology of HIV/STI Testing Patterns Among Gay, Bisexual, and Queer Men
Although factors associated with HIV/sexually transmitted infection (STI) testing among gay, bisexual, and queer (GBQ) men are well-established in the literature, few studies have attempted to delineate the processes underlying different patterns of testing. We conducted a qualitative study involving 35 semistructured interviews with a purposive sample of GBQ men in Singapore from October 2017 to July 2018. Topics explored included formative sexu…
Adequacy of public health communications on H7N9 and Mers in Singapore
Heightening education of infectious outbreaks through appropriate media to the young and less educated could increase awareness
Chemsex among gay, bisexual, and other men who have sex with men in Singapore and the challenges ahead
This study highlights the complexities behind chemsex use among GBMSM in Singapore, and the range of individual to institutional factors to be addressed. We recommend that community-based organisations and policy-makers find ways to destigmatise discussion of chemsex and provide safe spaces to seek help for drug use
Reproductive health services for refugees by refugees in Guinea I
This refugee self-help model appeared largely effective and could be considered for reproductive health needs in similar settings. Having any formal education appeared a major determinant of FP knowledge for men, while this was less noticeable for women. Thus, FP communication strategies for refugees should consider gender-specific messages and channels
Reproductive health for refugees by refugees in Guinea II
Our study revealed a high prevalence of STI symptoms, and gaps in sexual health knowledge in this displaced population. Learning about STIs from RHG health facilitators was associated with better knowledge. RHG's model could be considered in other complex emergency settings
Consequences of Automatic Evaluation
Research on automatic attitude activation has documented a pervasive tendency to nonconsciously classify most if not all incoming stimuli as either good or bad. Two experiments tested a functional explanation for this effect. The authors hypothesized that automatic evaluation results directly in behavioral predispositions toward the stimulus, such that positive evaluations produce immediate approach tendencies, and negative evaluations produce im…
Nonconscious Behavioral Confirmation Processes
It is now well-established that stereotypes can become activated unintentionally and outside of awareness by the presence of the relevant group features. There is also a long tradition of theory and evidence that perceptual and behavioral processes are intimately related (e.g., Berkowitz, 1984; James, 1890; Piaget, 1948). Considering these two phenomena together suggests that stereotype activation can cause the perceiver to act in stereotype-cons…
