Contextual factors associated with consistent condom use and condom self-efficacy amongst African asylum seekers and refugees in Hong Kong.

BACKGROUND: Hong Kong has no systematic domestic policies committed to the rights of asylum-seekers and refugees (ASRs). This study explores the sexual health behaviours and social inequities amongst African ASRs in Hong Kong. METHODS: A cross-sectional survey of African ASRs was conducted through three local non-governmental organizations in 2013. A logistic model was used to test the interactions and relationship between the respondents' consistent condom use and contextual antecedents, socio-demographic factors, psychosocial factors and condom self-efficacy (CSE) score. RESULTS: 371 adult African ASRs were recruited. In the previous month, 35% and 38% of participants consistently had used condoms with regular and casual sexual partners respectively. However, less than 50% perceived no risk of HIV/STIs and less than 60% reported not knowing how to access sexual health screening. Consistent condom use was less likely among African ASRs who were married (adjusted odds ratio (aOR) = 0.10), used recreational drugs (aOR = 0.11) or were unsure of their sexual orientation (aOR = 0.05) and was positively associated with higher CSE scores (aOR = 1.09) Pre-migration determinants and lifestyle determinants accounted for most of the variance in the model. CONCLUSION: The inconsistent condom use makes African ASRs vulnerable to HIV/STIs. Tailored interventions are needed to address the associated determinants and inequities amongst African ASRs living in Hong Kong.

Assessing Participation and Effectiveness of the Peer-Led Approach in Youth Sexual Health Education: Systematic Review and Meta-Analysis in More Developed Countries.

Sexual health education for young people is crucial not only for development of norms but also for protection against vulnerabilities during this stage in life. Although several systematic reviews have examined the effectiveness of peer-led sex education, none have focused on the extent of peer participation. The purpose of this review was to evaluate peer-led sexual health education interventions in more developed countries (MDCs). Electronic and manual searches across five social science, education, and medical databases were conducted. Fifteen articles were selected in total. Most (10 of 15) studies gave low or no responsibility to peers. The majority of articles found improvements in sexual health knowledge (13 of 14) and attitudes (11 of 15) at postintervention stages. Two studies showed improved self-efficacy, and three showed behavioral changes. A preliminary synthesis of effectiveness and level of participation was done. Meta-analysis revealed a large effect on knowledge change (Hedges' g = 0.84, 95% confidence interval [CI]: 0.43 to 1.25) and a medium effect on attitude change (Hedges' g = 0.49, 95% CI: 0.19 to 0.80). Peer-led interventions could be a powerful tool. This review shows that this approach is effective in changing knowledge and attitudes but not behaviors. Further research and action are needed to understand optimal implementation.

Prevalence and risk factors of chlamydia infection in Hong Kong: A population-based geospatial household survey and testing.

BACKGROUND: Chlamydia causes infertility and increases risk of HIV infection, and population-based studies provide essential information for effective infection control and prevention. This study examined Chlamydia trachomatis prevalence and risk factors among a representative sample of 18-49-year-old residents in Hong Kong. METHODS: Census boundary map of 412 constituency areas was used as primary sampling units to construct the sampling frame and, residential buildings and units were randomly selected using geospatial modelling. A questionnaire on sexual practice and health was conducted, and polymerase chain reaction was used to test the urine for genital chlamydial infection. Invitation letters were sent to the selected households and a team of interviewers were sent to recruit one subject per household. Prevalence data was weighted according to the 2011 census and risk factors identified through logistic regression. RESULTS: Among 881 participants (response rate of 24.5%), the overall Chlamydia trachomatis prevalence was low at 1.4% (95%CI 0.8-2.5%) but sexually active young (18-26 years) women had relatively high prevalence (5.8%, 95%CI 1.7-18.2%) in Hong Kong. A unique U-shape disease burden was observed with peaks in younger and older (40-49 years) women. Amongst the sexually active women, the risk factors of Chlamydia trachomatis infection were: younger age (aOR = 25.4, 95% CI 2.81-230); living alone (aOR = 8.99, 95% CI 1.46-55.40); and, among all the sexually active participants, males (including the male partners of the female participants) who had travelled out of Hong Kong in the previous 12 months had higher risks of infection (aOR = 5.35; 95% CI 1.25-22.8). A core-peripheral geographical distribution of Chlamydia trachomatis prevalence was also observed. CONCLUSION: Young and older sexually active women in Hong Kong have high prevalence of chlamydia. Routine screening for sexually active women and young men should be considered. Further research on testing feasibility and linkage-to-care are urgently needed to control the infection.

Mental health of African asylum-seekers and refugees in Hong Kong: using the social determinants of health framework.

BACKGROUND: Hong Kong is non-signatory to the 1951 Refugee Convention and its 1967 Protocol, and has no systematic domestic policies committed to the rights of asylum-seekers and refugees (ASRs). This creates a tenuous setting for African ASRs there. This study explored how mapped social determinates of health has impacted the mental health and wellbeing of African ASR's in Hong Kong. METHODS: A cross-sectional survey was carried out with 374 African ASRs. The survey comprised of: (a) socio-demographics; (b) health status; (c) health behaviours; and, (d) social experiences. Associations between social determinants of health and depression screen were explored and multivariable regression analysis was conducted. RESULTS: Majority of participants were 18-37 years old (79.7%), male (77.2%), single (66.4%) and educated (60.9% high school and above). Over a third (36.1%) screened positive for depression. Analyses revealed that living with family reduced the odds of a positive depression screen (OR = 0.25, 95%CI = 0.07-0.88). Those perceiving their health to be "Poor" were 5.78 times as likely to be screened for depression. Additionally, those with higher scores on the discrimination scale were more likely to have positive depression screen (OR = 1.17, 95%CI = 1.10-1.24). CONCLUSION: A significant proportion of African ASRs in Hong Kong exhibits depressive symptoms. A complex interaction combining both social and perceptions of health and discrimination in the host society is likely exacerbated by their ASR status. The use of community support groups or even re-examination of the family reunification laws could improve the mental health and wellbeing of African ASRs in Hong Kong.

Translation and Validation of a Condom Self-Efficacy Scale (CSES) Chinese Version.

The English version of the Condom Self-Efficacy Scale (CSES) was translated, back-translated, and tested among a representative sample of the Hong Kong general population. It then underwent reconsolidation, confirmation, and validation following standard procedures. Construct validity was performed by exploratory factor analysis and item-scale correlation. Independent t-test and effect size were used to identify the score differences between consistent and non-consistent condom users. The factor loading scores of 14 items ranged between 0.749 and 0.884. Cronbach's alpha for the traditional Chinese version of CSES (CSES-TC) was 0.96 for the overall scale. The CSES-TC was highly correlated with self-reported condom use among the 265 participants who indicated they had been sexually active in the past 12 months. The CSES-TC demonstrated satisfactory psychometric properties in terms of validity, reliability, and sensitivity. This scale can be used as an instrument to measure condom use efficacy for condom promotion and intervention purposes.

A lost tribe in the city: health status and needs of African asylum seekers and refugees in Hong Kong.

BACKGROUND: Hong Kong's resistance to be a signatory of the 1951 Geneva Convention and lack of domestic policies in this area has resulted in restrictions on access to healthcare amongst asylum seekers and refugees (ASRs). Using social determinants of health framework this study sought to identify health practices, problems and needs of African ASRs in Hong Kong. METHODS: A cross-sectional survey comprising of six domains including health status, health-seeking behaviour and social experience targeted at adult African ASRs in Hong Kong was conducted through three local non-governmental organisations between February and April 2013. Outpatient care and inpatient care in the past 12 months were used as proxy measures of general and severe ill health respectively. Associations between the determinants of health factors with general or severe health was explored through logistic regressions. RESULTS: Majority of 374 participants were young, single, educated males having been in Hong Kong for over 5 years. A third of ARS (36.1 %) screened positive for depression. Most reported problems related to basic necessities (64.7-78.6 %) and access to health services (72.2 %). ASRs with relatively less education, health awareness or higher risk behaviours were less likely to have obtained outpatient or inpatient services. African ASRs reporting problems with case officers (aOR = 2.80; 95 % CI = 1.35-5.79) or illness in the past 30 days (aOR = 6.00; 95 % CI = 2.94-12.25) were more likely to report general ill health. Similarly, problems with the case officers (aOR = 3.76; 95 % CI = 1.97-7.18) and self-reported illness in the past 30 days (a​OR = 3.32; 95 % CI= 1.68-6.57) were also significantly associated with severe ill health. At the health system level, those who reported experiencing difficulties accessing the medical services in Hong Kong are 3.29 (95 % CI = 1.48-7.31) and 4.12 (95 % CI = 1.73-9.79) times as likely to report general and severe ill health respectively. CONCLUSION: The host government should have moral and ethical obligations to attend to the health needs of ASRs. Evidently a number of structural and health system factors have significantly impacted the health of African ASRs in Hong Kong. Changes to current policies regarding how African ASRs are handled whilst in Hong Kong but, more immediately, improvements in healthcare access are needed.
