Overcoming Barriers to Mammography Screening: A Quasi-randomised Pragmatic Trial in a Community-based Primary Care Setting

<p><b>INTRODUCTION</b>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.</p><p><b>MATERIALS AND METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>

Challenges of respondent driven sampling to assess sexual behaviour and estimate the prevalence of human immunodeficiency virus (HIV) and syphilis in men who have sex with men (MSM) in Singapore

There is a lack of representative samples to provide reliable and accurate seroprevalence of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) as well as behavioural information among men who have sex with men (MSM) in Singapore. We used respondent driven sampling (RDS) to recruit MSM. Participants completed a survey used by Asian Internet MSM Sex Survey (AIMSS) and were tested for HIV and syphilis. We compared the characteristics of the RDS participants with STI diagnosis against those who did not have any STI diagnosis in the past 6 months. We compared RDS participants with AIMSS participants. Of 72 MSM recruited, 1 was positive for HIV (1.3%) and 4 (5.5%) tested positive for syphilis. Median age was 30 years and majority was Chinese (69.4%). RDS participants who had any STI diagnosis reported to have more use of recreational drugs (P = 0.006), and lower condom use (P = 0.054). Comparing RDS participants (n = 72) with the AIMSS participants (n = 2075), RDS respondents had ≥1 male partner in the past 6 months (P = 0.003), more casual sex partners (P = 0.012) and more STI symptoms (P = 0.019). There was no difference in terms of HIV testing and recreational drug use. The HIV and syphilis seroprevalence rates from our study are similar to previous reports conducted in high-risk MSM. In contrast to other settings, RDS did not work well among MSM in Singapore. The public health implications of our study highlight the challenges in obtaining data for HIV surveillance in assessing prevalence and risk behaviours among MSM.

Do parents talk to their adolescent children about sex?--findings from a community survey in Singapore

<p><b>INTRODUCTION</b>Sexually transmitted infections have increased sharply among adolescents both locally and internationally in recent years. Parents play an important role in their children's sexual health development. An integral part of this includes effective parent-child sexuality communication.</p><p><b>MATERIALS AND METHODS</b>A nationwide cross-sectional community-based household survey was conducted in Singapore between August 2008 and March 2009 to assess parents'/caregivers' attitudes and practices regarding caregiver-child sexuality communication. With an overall response rate of 81.4%, 1169 questionnaires from parents/caregivers of children aged 10 to 17 years were analysed.</p><p><b>RESULTS</b>Almost all (94.2%) the caregivers were parents. A majority (>80%) of caregivers considered talking to their children about sexuality issues such as abstinence, consequences of premarital sex and condom use as important. However, a significantly lower percentage (about 60%) felt comfortable and confident doing so. Only 8.3% among them discussed sexual health issues with their children very often, 37.2% sometimes, 22.0% seldom/hardly ever (once or twice) and 32.5% never, in the past year. In the multivariate analysis, caregiver-child sexuality communication was significantly associated with caregivers' relationship to children, ethnicity, educational level, and their perceived levels of comfort and confidence in sexuality communication.</p><p><b>CONCLUSION</b>Caregivers generally felt it was important but were significantly much less comfortable and confident talking about sexuality issues with their children, which leads to a lower frequency of caregiver-child sexuality communication. Educational programmes on adolescent sexual health targeting parents/caregivers are needed. They must be equipped with skills and provided with resources to enable them to talk to their adolescent children about sexuality.</p>

Human immunodeficiency virus (HIV) prevention education in Singapore: challenges for the future

We reviewed the current human immunodeficiency virus (HIV) prevention education programmes in Singapore, discussed the challenges faced and proposed prevention education interventions for the future. Education programmes on HIV prevention have shown some success as seen by reduced visits to sex workers among the general adult population and a marked increase in condom use among brothel-based sex workers. However, we still face many challenges such as low awareness of HIV preventive strategies and high prevalence of HIV stigma in the general population. Voluntary HIV testing and condom use remain low among the priority groups such as men who have sex with men (MSM) and heterosexual men who buy sex. Casual sex has increased markedly from 1.1% in 1989 to 17.4% in 2007 among heterosexuals in Singapore, with the majority (84%) practising unprotected sex. Sex workers have moved from brothels to entertainment venues where sex work is mostly hidden with lack of access to sexually transmitted infections (STIs)/ HIV prevention education and treatment programmes. Education programmes promoting early voluntary testing is hampered because of poor access, high cost and stigma towards people living with HIV. It remains a challenge to promote abstinence and consistent condom use in casual and steady sexual relationships among heterosexuals and MSM. New ways to promote condom use by using a positive appeal about its pleasure enhancing effects rather than the traditional disease-oriented approach should be explored. Education programmes promoting early voluntary testing and acceptance of HIV-infected persons should be scaled up and integrated into the general preventive health services.

Public misperceptions about transmission of hepatitis B virus in Singapore

<p><b>INTRODUCTION</b>Hepatitis B virus (HBV) infection is endemic in Asia. Good public knowledge on disease transmission is one way of controlling spread of HBV. We aimed to study the general knowledge on HBV among the general public in Singapore, which is moderately prevalent with HBV.</p><p><b>MATERIALS AND METHODS</b>Before conducting a public education seminar on liver diseases, a 16-point questionnaire survey was conducted among the participants. Misperceptions (if any) were identified, and factors associated with knowledge score were analysed by multivariate analysis.</p><p><b>RESULTS</b>One hundred and ninety-two subjects completed the questionnaire. The mean age was 52 years, 78 (41%) were male, 183 (95%) were Chinese, 17 (9%) were known hepatitis B carriers and 73 (38%) had completed college education. The mean knowledge score was 10.7 (out of a maximum of 16). Most misperceptions were in the category of HBV transmission. At multivariate analysis, having college education was the only independent factor associated with a high knowledge score.</p><p><b>CONCLUSION</b>Although HBV infection is moderately prevalent in Singapore, many misperceptions existed among the general public, especially on the mode of transmission. Better education was related to better knowledge of HBV. Further public education should be targeted to clear the misperceptions identified, and be specifically targeted to the less educated.</p>
