RESUMO
BACKGROUND: Health screening is undertaken to identify individuals who are deemed at higher risk of disease for further diagnostic testing so that they may possibly benefit from interventions to modify the natural course of disease. In Singapore, screening tests are widely available in the form of a package, which bundles multiple tests in one session and commonly includes non-recommended tests. There are various ethical issues associated with such testing as they may not be clinically appropriate and can result in more harm than benefit. This article describes the practice of health screening packages, identifies the ethical issues arising from such packages and discusses the implications of these ethical issues on policy and practice of screening in Singapore. METHODS: A content analysis of the websites of providers offering general health screening packages to individuals was conducted. A total of 14 health screening package providers were analysed for how packages were conducted and promoted, how clinically appropriate screening tests were, and the price range and composition of screening packages. A normative ethical analysis based on the four principles approach of beneficence, non-maleficence, autonomy and justice in biomedical ethics was used. RESULTS: Twelve of the 14 providers included non-recommended tests such as tumour markers, treadmill stress tests and MRI scans in their general health screening packages. Package prices ranged from S$26 to S$10,561, with providers charging higher when more tests were included. Health screening packages were broadly conducted in three stages: (1) the offer and selection of a health screening package; (2) medical assessment and performance of screening tests; (3) a post-screening review. While material provided by all providers was factual, there was no information on the potential risks or harms of screening. CONCLUSION: Several ethical issues were identified that should be addressed with regard to health screening packages in Singapore. A key issue was the information gap between providers and patients, which may result in patients undergoing inappropriate testing that may be more harmful than beneficial. Health screening packages can stimulate unnecessary demand for healthcare and contribute to an inequitable distribution of healthcare resources.

OBJECTIVES: Follow-up colonoscopy after a positive faecal immunochemical test (FIT) in any colorectal cancer (CRC) screening programme is integral. However, many individuals who had a positive FIT declined colonoscopy subsequently. This study aims to uncover the predictors on completion of colonoscopy using the Health Belief Model (HBM) between individuals who complete and those who did not after a positive FIT. METHODS: A mixed-method study comprising qualitative semi-structured interviews followed by a locally validated questionnaire in Singapore was prospectively administered via telephone interview to average risk individuals with positive FIT results from a cohort of the national FIT screening database referred for follow-up colonoscopic evaluation. RESULTS: A total of 394 individuals, with a median age of 66 years (range, 46-89 years), were recruited. Fifty percent completed follow-up colonoscopic evaluation and formed the "doers" group. All participants demonstrated high knowledge of symptoms of CRC and awareness and qualitative responses were aligned to the various HBM domains. Using multi-variable analysis, doers felt that medical recommendations (odds ratio [OR], 2.39, 95% confidence interval [CI]: 1.23-4.63, p = 0.01) and mainstream media publicity (OR, 2.16, 95% CI: 1.09-4.26, p = 0.026) were important. Non-doers showed positive association with perceived barriers such as cost (OR, 2.15, 95% CI: 1.10-4.20, p = 0.026) and inconvenience (OR, 3.44, 95% CI: 1.50-7.89, p = 0.004). CONCLUSIONS: Identified factors such as tackling perceived barriers, public health education and active promotion by medical physicians, family and friends could help guide subsequent interventions to improve compliance of individuals with positive FIT to undergo follow-up colonoscopy.

We evaluated the impact of the coronavirus disease (COVID-19) on the sex work industry and assessed how it has impacted the health and social conditions of sex workers in Singapore. We conducted a sequential exploratory mixed methods study amidst the COVID-19 pandemic from April to October 2020, including in-depth interviews with 24 stakeholders from the sex work industry and surveyor-administered structured surveys with 171 sex workers. COVID-19 had a substantial impact on sex workers' income. The illegality of sex work, stigma, and the lack of work documentation were cited as exclusionary factors for access to alternative jobs or government relief. Sex workers had experienced an increase in food insecurity (57.3%), housing insecurity (32.8%), and sexual compromise (8.2%), as well as a decrease in access to medical services (16.4%). Being transgender female was positively associated with increased food insecurity (aPR = 1.23, 95% CI [1.08, 1.41]), housing insecurity (aPR = 1.28, 95% CI [1.03, 1.60]), and decreased access to medical services (aPR = 1.74, 95% CI [1.23, 2.46]); being a venue-based sex worker was positively associated with increased food insecurity (aPR = 1.46, 95% CI [1.00, 2.13]), and being a non-Singaporean citizen or permanent resident was positively associated with increased housing insecurity (aPR = 2.59, 95% CI [1.73, 3.85]). Our findings suggest that COVID-19 has led to a loss of income for sex workers, greater food and housing insecurity, increased sexual compromise, and reduced access to medical services for sex workers. A lack of access to government relief among sex workers exacerbated such conditions. Efforts to address such population health inequities should be implemented.

BACKGROUND: Primary care patients with prediabetes is a priority group in the clinical, organisational and policy contexts. Engaging in regular physical activity is crucial to prevent diabetes for this group. The objectives of the study were to assess factors associated with meeting the recommendation of at least 150 min of moderate/vigorous physical activity weekly, and to explore facilitators and barriers related to the behaviour among primary care patients with prediabetes in Singapore. METHODS: This was a mixed methods study, consisting of a cross-sectional survey involving 433 participants from 8 polyclinics, and in-depth interviews with 48 of them. Adjusted prevalence ratios (aPR) were obtained by mixed effects Poisson regression model. The socio-ecological model (SEM) was applied, and thematic analysis performed. RESULTS: The prevalence of meeting the recommendation was 65.8%. This was positively associated with being male (aPR 1.21, 95%CI 1.09-1.34), living in 4-5 room public housing (aPR 1.19, 95%CI 1.07-1.31), living in executive flat/private housing (aPR 1.26, 95%CI 1.06-1.50), having family members/friends to exercise with (aPR 1.57, 95%CI 1.38-1.78); and negatively associated with a personal history of osteoarthritis (aPR 0.75, 95%CI 0.59-0.96), as well as time spent sitting or reclining daily (aPR 0.96, 95%CI 0.94-0.98). The recurrent themes for not meeting the recommendation included lacking companionship from family members/friends, medical conditions hindering physical activity (particularly osteoarthritis), lacking knowledge/skills to exercise properly, "no time" to exercise and barriers pertaining to exercise facilities in the neighbourhood. The recurrent themes for meeting the recommendation included family/peer influence, health/well-being concerns and education by healthcare professionals. CONCLUSIONS: Much more remains to be done to promote physical activity among primary care patients with prediabetes in Singapore. Participants reported facilitators and barriers to physical activity at different levels of the SEM. Apart from the individual and interpersonal levels, practitioners and policy makers need to work together to address the organisational, community and policy barriers to physical activity.

AIMS: To assess factors associated with ever receiving prediabetes education, and to explore the health education and communication needs among primary care patients with prediabetes in Singapore. METHODS: A mixed methods study, consisting of a cross-sectional survey involving 433 patients with prediabetes aged 21-79, and in-depth interviews (IDIs) with 48. Multivariable regression was used to analyse the survey results, while thematic analysis was used to analyse the IDIs. RESULTS: The prevalence of ever receiving prediabetes education was 26.6%. This was positively associated with school education, impaired glucose tolerance, number of co-morbidities, having family or peer with diabetes, having support to reduce diabetes risk, confidence to self-manage prediabetes, and negatively associated with age. A common reason among those not receiving such education was not being referred by doctors. The preferred content of health communication messages were to focus on risk and prevention of diabetes, health and family, and to avoid the term 'prediabetes' in messages. The top 2 preferred education components were healthy eating and physical activity, and the most desired setting was the community centre. CONCLUSIONS: More efforts are needed to increase the take-up rate of prediabetes education. Polyclinic healthcare professionals could provide preliminary advice, and subsequently refer patients to community-based programmes or resources.

OBJECTIVE: Malays, with majority of the individuals being Muslim, form the largest ethnic group in Southeast Asia. This region is experiencing a rising incidence of HIV infections. Due to circumcision and prohibition of sex outside marriage, being Muslim was argued to be a protective factor against sexually transmitted infections (STI) and Human Immunodeficiency Virus (HIV). However, Malay adolescents were found to be more likely to contract chlamydia and gonorrhea than non-Malay adolescents in Singapore. DESIGN: Using a cross-sectional survey, we examined and compared safer sex knowledge, attitudes and self-efficacy, and sexual behaviors of 248 sexually active Malay adolescents with 384 Chinese adolescents aged 16-19 years in Singapore. Poisson regression, adjusted for socio-demographic characteristics, was used for modeling each dependent variable. Adjusted prevalence ratios (aPR) with 95% confidence intervals (CI) were obtained. RESULTS: On multivariate analysis, Malay adolescents were more likely to report marginally unfavorable attitude towards condom use (aPR 1.21 CI 1.00-1.48) and significantly lower confidence in using condoms correctly (aPR 1.24 CI 1.05-1.47) than Chinese adolescents. They were also more likely to report significantly younger first sex age (aPR 0.98 CI 0.96-1.00), never use of condoms for vaginal sex (aPR 1.32 CI 1.16-1.49) and anal sex (aPR 1.75 CI 1.11-2.76) and non-use of contraceptives at last sex (aPR 1.30 CI 1.17-1.45) than Chinese respondents. Malay males were less likely to buy sex (aPR 0.56 CI 0.37-0.85), but they reported higher likelihood of inconsistent condom use with female sex workers (aPR 2.24 CI 1.30-3.87). CONCLUSION: Malay ethnicity was associated with unfavorable condom use attitude and lower self-efficacy in using condoms, which was consistent with risky sexual behaviors such as non-use of condoms. Future research should use mixed methods to explore and identify cultural influences to these behaviors.

BACKGROUND: We assessed the efficacy of a multi-component sexual health promotion program on condom use and human immunodeficiency virus (HIV)/sexually transmitted infection (STI) testing among heterosexual men (HSM) patronizing entertainment establishments who engaged in casual or paid sex in Singapore. METHODS: This was a quasi-experimental trial with a comparison group using cross-sectional surveys at baseline and 6 months postintervention. A locality patronized by local HSM was assigned the intervention, a comparable and distant area served as the comparison site. Using time location sampling, cross-sectional samples of these men were assessed on sexual behaviors using an anonymous questionnaire at baseline (n = 604) and 6 months postintervention (n = 360) in both groups. The coprimary outcomes were condom use at last vaginal and oral sex with casual partner respectively. Mixed effects Poisson regression model accounting for clustering by establishment was used to compute the adjusted prevalence ratio (aPR) of the outcomes postintervention. RESULTS: At postintervention, the intervention group was more likely than the comparison group to report condom use at last vaginal (aPR, 1.41; 95% confidence interval [CI], 1.05-1.89) and oral (aPR, 1.70; 95% CI. 1.11-2.61) sex, respectively, with casual partner. Similar findings were found for consistent condom use in the last 6 months for vaginal (aPR, 1.67; 95% CI, 1.13-2.48) and oral (aPR, 1.97; 95% CI, 1.16-3.32) sex, respectively, with casual partner. The HIV/STI testing was not significantly higher in the intervention than the comparison group (aPR, 1.43; 95% CI, 0.98-2.09). CONCLUSIONS: This trial was effective in promoting condom use with casual partners but not HIV/STI testing among HSM in Singapore.

INTRODUCTION: First degree relatives (FDR) of colorectal cancer (CRC) patients are at increased risk of CRC compared to the general population. However, screening colonoscopy rates amongst the FDRs remain dismal. The aim of the study was to explore the various issues amongst the patients and their FDR precluding their adoption of screening colonoscopy. METHODS: A qualitative study of CRC patients and their FDRs was performed. Semi-structured interviews were conducted with participants using open-ended questions until data saturation was achieved. These qualitative data were then thematically analysed. RESULTS: Fifty CRC patients and thirty-one FDRs were recruited between June 2015 and December 2015. For the patients, three main themes emerged, which include (i) poor understanding of the CRC screening guidelines for their FDRs, (ii) recommendations are lacking amongst medical professionals and (iii) numerous barriers are hindering patients from being advocates for screening colonoscopy for their FDRs. For the FDRs, three main themes emerged. These include (i) poor understanding of the exact CRC screening guidelines amongst the FDRs, (ii) the lack of health promotion efforts amongst medical professionals and (iii) barriers to the uptake of screening colonoscopy such as fear of colonoscopy, high cost of the procedure, its associated inconvenience and perceived invulnerability of the individual. CONCLUSIONS: Patients and FDRs are not aware of the increased risks of developing CRC amongst the family members. Guidelines regarding screening are also not clearly understood. The numerous barriers that are present amongst the CRC patients and their FDRs can be addressed.

OBJECTIVES: We assessed the proportion of and socio-ecological factors associated with ever having had sex with female sex workers (FSWs) among heterosexual adolescents. We also described the characteristics of the adolescents who reported inconsistent condom use with FSWs. METHODS: This is a cross-sectional study (response rate: 73%) of 300 heterosexually active male adolescents of 16 to 19 years attending a national STI clinic in Singapore between 2009 and 2014. We assessed the ecological factors (individual, parental, peer, school and medial influences) and sexual risk behaviors using a self-reported questionnaire. Poisson regression was used to obtain the adjusted prevalence ratios (aPR) and confidence intervals (CI). RESULTS: The proportion of heterosexual male adolescents who had ever had sex with FSWs was 39%. Multivariate analysis showed that significant factors associated with ever having had sex with FSWs were sex initiation before 16 years old (aPR 1.79 CI: 1.30-2.46), never had a sexually active girlfriend (aPR 1.75 CI 1.28-2.38), reported lower self-esteem score (aPR 0.96 CI: 0.93-0.98), higher rebelliousness score (aPR 1.03 CI: 1.00-1.07) and more frequent viewing of pornography (aPR 1.47 CI: 1.04-2.09). Lifetime inconsistent condom use with FSWs was 30%. CONCLUSIONS: A significant proportion of heterosexual male adolescents attending the public STI clinic had ever had sex with FSWs. A targeted intervention that addresses different levels of influence to this behavior is needed. This is even more so because a considerable proportion of adolescents reported inconsistent condom use with FSWs, who may serve as a bridge of STI transmission to the community. National surveys on adolescent health should include the assessment of frequency of commercial sex visits and condom use with FSWs for long-term monitoring and surveillance.

INTRODUCTION: Breast cancer is the leading cancer among women in Singapore. Five years after a population-wide breast cancer screening programme was introduced, screening rates remained relatively low at 41%. Studies have shown decreased screening propensity among medically underserved women typically of minority or socioeconomically disadvantaged status. We conducted a quasi-randomised pragmatic trial aimed at encouraging mammography screening among underscreened or unscreened women in a publicly funded primary care facility in Singapore. MATERIALS AND METHODS: The study was conducted from May to August 2010. Components of intervention included (1) tailored education, (2) doctor's reminder, and (3) cost reduction. Researchers administered a structured questionnaire to eligible female polyclinic attendees and patient companions aged 40 to 69 years. Individual knowledge, attitudes, beliefs, and barriers towards mammography screening were identified and educational messages tailored. Doctor's reminder and cost reduction were implemented additively. RESULTS: Overall, out of 448 participants, 87 (19.4%, 95% confidence interval (CI), 15.8% to 23.1%) completed mammography screening across 3 arms of study. Participants who received a cost reduction were more likely to attend screening compared to participants in other intervention arms (adjusted odds ratio (OR) 2.4, 95% CI, 1.2 to 4.5, P = 0.009). Cost of screening, ethnicity, prior screening history, and attitudes towards mammography screening were identified as significant factors predicting mammogram attendance. CONCLUSION: Including a cost reduction component was the most effective intervention that increased mammography screening rates. Women's underlying beliefs, attitudes, and other predisposing factors should also be considered for integration into existing breast cancer screening programmes.

BACKGROUND: Colorectal Cancer (CRC) is rapidly rising in Asia, but screening uptake remains poor. Although studies have reported gender differences in screening rates, there have been few studies assessing gender specific perceptions and barriers towards CRC screening, based on behavioral frameworks. We applied the Health Belief Model to identify gender-specific predictors of CRC screening in an Asian population. METHODS: A nationwide representative household survey was conducted on 2000 subjects aged 50 years and above in Singapore from 2007 to 2008. Screening behaviour, knowledge and beliefs on CRC screening were assessed by face-to-face structured interviews. The response rate was 88.2%. RESULTS: 26.7 percent had undergone current CRC screening with no gender difference in rates. Almost all agreed that CRC would lead to suffering (89.8%), death (84.6%) and would pose significant treatment cost and expense (83.1%). The majority (88.5%) agreed that screening aids early detection and cure but only 35.4% felt susceptible to CRC. Nearly three-quarters (74.3%) of the respondents recalled reading or hearing information on CRC in the print or broadcast media. However, only 22.6% were advised by their physicians to undergo screening. Significantly more women than men had feared a positive diagnosis, held embarrassment, pain and risk concerns about colonoscopy and had friends and family members who encouraged screening. On multivariate analysis, screening uptake showed a positive association with worry about contracting CRC and a physician's recommendation and a negative association with perceived pain about colonoscopy for both genders. For women only, screening was positively associated with having attended a public talk on CRC and having a family member with CRC, and was negatively associated with Malay race and perceived danger of colonoscopy. CONCLUSIONS: CRC screening remains poor despite high levels of awareness of its benefits in this Asian population. Race, worry about contracting cancer, psychological barriers, and cues from the doctor and a public talk on CRC were associated with screening with gender specific differences. Strategies to increase CRC screening uptake should consider gender specific approaches to address psychological barriers and increase disease susceptibility through public health education and active promotion by physicians.

Community health psychology provides a framework for local citizens themselves to systematically affect change in health and social inequalities, particularly through Participatory Action Research (PAR). The Cambodian NGO SiRCHESI launched a 24-month Hotel Apprenticeship Program (HAP) in 2006 to provide literacy, English, social skills, health education, hotel skills-training, work experience and a living wage to women formerly selling beer in restaurants; there they had faced workplace risks including HIV/AIDS, alcohol overuse, violence and sexual coercion. Quantitative and qualitative analyses indicate changes in health-related knowledge, behaviour, self-image and empowerment, as HAP trainees were monitored and evaluated within their new career trajectories.

BACKGROUND: Adoption of the objective structured clinical examination may be hindered by shortages of clinicians within a specialty. Clinicians from other specialties should be considered as alternative, non-expert examiners. AIMS: We assessed the inter-rater agreement between expert and non-expert clinician examiners in an integrated objective structured clinical examination for final year medical undergraduates. METHODS: Pairs of expert and non-expert clinician examiners used a rating checklist to assess students in 8 oral communication stations, representing commonly encountered scenarios from medicine, paediatrics, and surgery. These included breaking bad news, managing an angry relative, taking consent for lumbar puncture; and advising a mother on asthma and febrile fits, and an adult on medication use, lifestyle changes and post-suture care of a wound. 439 students participated in the OSCE (206 in 2005, 233 in 2006). RESULTS: There was good to very good agreement (intraclass coefficient: 0.57-0.79) between expert and non-expert clinician examiners, with 5 out of 8 stations having intraclass coefficients > or =0.70. Variation between paired examiners within stations contributed the lowest variance to student scores. CONCLUSION: These findings support the use of clinicians from other specialties, as 'non-expert' examiners, to assess communication skills, using a standardized checklist, thereby reducing the demand on clinicians' time.
