Comparison of three intervention models for promoting circumcision among migrant workers in western China to reduce local sexual transmission of HIV

Promoting labour migrant health equity through action on the structural determinants: a systematic review

Background

Labour migrants, who represent over sixty per cent of international migrants globally, frequently have poorer health status than the population of host countries. These health inequities are determined in a large part by structural drivers including political, commercial, economic, normative and social factors, including living and working conditions. Achieving health equity for migrant workers requires structural-level interventions to address these determinants.

Methods

We undertook a systematic review of peer-reviewed literature designed to answer the question “what is the evidence for the effectiveness of interventions to address the structural determinants of health for labour migrants?” using the Ovid Medline electronic database.

Findings

We found only two papers that evaluated structural interventions to improve the health of labour migrants. Both papers evaluated the impact of insurance – health or social. In contrast, we found 19 evaluations of more proximal, small-scale interventions focused on changing the knowledge, attitudes and behaviours of labour migrants.

Interpretation

Despite the rise in international migration, including for work, and evidence that labour migrants have some higher health risks, there is a paucity of research addressing the structural determinants of health inequities in labour migrants. The research community (including funders and academic institutions) needs to pay greater attention to the structural determinants of health – which generally requires working across disciplines and sectors and thinking more politically about health and health inequities.

Health and well-being issues of Nepalese migrant workers in the Gulf Cooperation Council countries and Malaysia: a systematic review

OBJECTIVE

To summarise the evidence on health and well-being of Nepalese migrant workers in the Gulf Cooperation Council (GCC) countries and Malaysia.

DESIGN

Systematic review.

DATA SOURCES

EMBASE, MEDLINE, Scopus and Global Health databases.

ELIGIBILITY CRITERIA

Studies were eligible if they: (1) included Nepalese migrant workers aged 18 or older working in the GCC countries or Malaysia or returnee migrant workers from these countries; (2) were primary studies that investigated health and well-being status/issues; and (3) were published in English language before 8 May 2020.

STUDY APPRAISAL

All included studies were critically appraised using Joanna Briggs Institute study specific tools.

RESULTS

A total of 33 studies were eligible for inclusion; 12 studies were conducted in Qatar, 8 in Malaysia, 9 in Nepal, 2 in Saudi Arabia and 1 each in UAE and Kuwait. In majority of the studies, there was a lack of disaggregated data on demographic characteristics of Nepalese migrant workers. Nearly half of the studies (n=16) scored as 'high' quality and the rest (n=17) as 'moderate' quality. Five key health and well-being related issues were identified in this population: (1) occupational hazards; (2) sexual health; (3) mental health; (4) healthcare access and (5) infectious diseases.

CONCLUSION

To our knowledge, this is the most comprehensive review of the health and well-being of Nepalese migrant workers in the GCC countries and Malaysia. This review highlights an urgent need to identify and implement policies and practices across Nepal and destination countries to protect the health and well-being of migrant workers.

A Randomized Controlled Trial Evaluating Efficacy of a Brief Setting-Based and Theory-Based Intervention Promoting Voluntary Medical Male Circumcision Among Heterosexual Male Sexually Transmitted Disease Patients in China

Voluntary medical male circumcision (VMMC) is an evidence-based biomedical HIV prevention but under-utilized by male sexually transmitted diseases patients (MSTDP) in China. A parallel-group, non-blinded randomized controlled trial was conducted. Participants were uncircumcised heterosexual MSTDP attending four sexually transmitted diseases (STD) clinics in three Chinese cities. A total of 244 MSTDP were randomized 1:1 into the intervention group (n = 108) and the control group (n = 136). In addition to the education booklet received by the control group, the intervention group watched a 10-min video clip and received a brief counseling delivered by clinicians in the STD clinics. The interventions were developed based on the Health Belief Model and the Theory of Planned Behavior. At Month 6, participants in the intervention group reported significantly higher uptake of VMMC (14.8% versus 2.9%; RR 5.03, 95% CI 1.73, 14.62, p = 0.001). The brief STD clinic-based intervention was effective in increasing VMMC uptake among MSTDP in China.Trial registry: This study is registered at ClinicalTrials.gov, number NCT03414710. https://clinicaltrials.gov/ct2/show/NCT03414710 .

Results of a Cluster Randomized Controlled Trial to Promote the Use of Respiratory Protective Equipment among Migrant Workers Exposed to Organic Solvents in Small and Medium-Sized Enterprises

Background: Existing evidence shows an urgent need to improve respiratory protective equipment (RPE) use, and more so among migrant workers in small and medium-sized enterprises (SMEs). The study aimed to assess the effectiveness of a behavioral intervention in promoting the appropriate use of RPE among internal migrant workers (IMWs) exposed to organic solvents in SMEs. Methods: A cluster randomized controlled trial was conducted among 1211 IMWs from 60 SMEs in Baiyun district in Guangzhou, China. SMEs were deemed eligible if organic solvents were constantly used in the production process and provided workers with RPE. There were 60 SMEs randomized to three interventions on a 1:1:1 ratio, namely a top-down intervention (TDI), a comprehensive intervention, and a control group which did not receive any intervention. IMWs in the comprehensive intervention received a module encompassing three intervention activities: An occupational health education and training component (lectures and leaflets/posters), an mHealth component in the form of messages illustrative pictures and short videos, and a peer education component. The TDI incorporated two intervention activities, namely the mHealth and occupational health education and training components. The primary outcome was the self-reported appropriate RPE use among IMWs, defined as using an appropriate RPE against organic solvents at all times during the last week before measurement. Secondary outcomes included IMWs' occupational health knowledge, attitude towards RPE use, and participation in occupational health check-ups. Data were collected and assessed at baseline, and three and six months of the intervention. Generalized linear mixed models were performed to evaluate the effectiveness of the trial. Results: Between 3 August 2015 and 29 January 2016, 20 SMEs with 368 IMWs, 20 SMEs with 390 IMWs, and 20 SMEs with 453 IMWs were assigned to the comprehensive intervention, the TDI, and the control group, respectively. At three months, there were no significant differences in the primary and secondary outcomes among the three groups. At six months, IMWs in both intervention groups were more likely to appropriately use RPE than the control group (comprehensive intervention: Adjusted odds ratio: 2.99, 95% CI: 1.75-5.10, p < 0.001; TDI: 1.91, 95% CI: 1.17-3.11, and p = 0.009). Additionally, compared with the control group, the comprehensive intervention also improved all three secondary outcomes. Conclusions: Both comprehensive and top-down interventions were effective in promoting the appropriate use of RPE among IMWs in SMEs. The comprehensive intervention also enhanced IMWs' occupational health knowledge, attitude, and practice. Trial registration: ChiCTR-IOR-15006929. Registered on 15 August 2015.

Migrant Workers and Physical Health: An Umbrella Review

Migrants are mainly employed in “3D jobs” which are dirty, dangerous, and difficult, are characterized by monotony and intense rhythms, and are found in sectors with higher risks such as construction, heavy industry, and agriculture. The aim of this study is to construct a systematic review in order to identify the main occupational risks and occupational diseases of this category. Research included articles published from 2013 to 2018 on major online databases (PubMed, Cochrane Library, and Scopus), which were obtained using a combination of keywords (migrant workers, expatriates, physical health, diseases, illnesses, travel, travelers, work, and occupational medicine). The online search included 1109 references. We excluded 977 studies because they were unrelated to physical health and another 64 due to duplication. There were 68 articles which were analyzed, including six reviews and 62 original articles. The main risks which emerged are developing infectious diseases, metabolic cardiovascular diseases and manifesting a lower quality of life, in particular due to difficulties in accessing local health services. It will be crucial to implement the role of occupational medicine in order to introduce multilevel interventions designed to prevent work-related injuries and illnesses, and to promote healthier working environments.

Impact of Educational Interventions on Acceptance and Uptake of Male Circumcision in the General Population of Western China: A Multicenter Cohort Study

To compare different intervention models for promoting male circumcision (MC) to prevent HIV transmission in Western China. A total of 1690 male participants from multiple study sites were cluster randomly allocated to three-stage (Model A), two-stage (Model B), and one-stage (Model C) educational interventions. In all three interventions models, knowledge about MC significantly increased and the reported willingness to accept MC increased to 52.6% (255/485), 67.0% (353/527), and 45.5% (219/481) after intervention, respectively (P < 0.05). Rate of MC surgery uptake was highest (23.7%; 115/485) among those who received Model A intervention, compared to those who received Model B (17.1%; 90/527) or Model C (9.4%; 45/481) interventions (P < 0.05). Multivariable Cox regression analysis identified that Model A or Model B had twice the effect of Model C on MC uptake, with relative risks of 2.4 (95%CI, 1.5-3.8) and 2.2 (95%CI, 1.3-3.6), respectively. Model B was the most effective model for improving participants' willingness to accept MC, while Model A was most successful at increasing uptake of MC surgery. Self-reported attitude towards MC uptake was not strongly correlated with actual behavior in this study focusing on the general male population in Western China.

"I Feel Like More of a Man": A Mixed Methods Study of Masculinity, Sexual Performance, and Circumcision for HIV Prevention

Ethnographic studies from numerous societies have documented the central role of male circumcision in conferring masculinity and preparing boys for adult male sexuality. Despite this link between masculinity, sexuality, and circumcision, there has been little research on these dynamics among men who have been circumcised for HIV prevention. We employed a mixed methods approach with data collected from recently circumcised men in the Dominican Republic (DR) to explore this link. We analyzed survey data collected six to 12 months post-circumcision (N = 293) as well as in-depth interviews conducted with a subsample of those men (n = 30). We found that 42% of men felt more masculine post-circumcision. In multivariate analysis, feeling more masculine was associated with greater concern about being perceived as masculine (OR = 1.70, 95% CI: 1.25-2.32), feeling more potent erections post-circumcision (OR = 2.25, 95% CI: 1.26-4.03), and reporting increased ability to satisfy their partners post-circumcision (OR = 2.30, 95% CI: 1.11-4.77). In qualitative interviews, these factors were all related to masculine norms of sexually satisfying one's partner, and men's experiences of circumcision were shaped by social norms of masculinity. This study highlights that circumcision is not simply a biomedical intervention and that circumcision programs need to incorporate considerations of masculine norms and male sexuality into their programming.

Needs Assessment and Theory-Based Promotion of Voluntary Medical Male Circumcision (VMMC) Among Male Sexually Transmitted Diseases Patients (MSTDP) in China

Voluntary medical male circumcision (VMMC) is an evidence-based biomedical HIV prevention method. It is under-utilized in countries outside Africa, including China. The present single-arm, non-blinded test-of-concept trial was designed to promote VMMC among 179 male sexually transmitted diseases patients (MSTDP) in Shenzhen, China. It was based on behavioral health theories and results of a formative survey. At month 4, 45.5 % of the MSTDP responded positively to the intervention (19.9 % had taken up VMMC and 25.6 % intended to do so in the next 6 months). Adjusted analysis showed that cognitive variables measured at baseline (perceived self-efficacy, subjective norm and behavioral intention) significantly predicted adoption of VMMC during the 4-month follow-up period. Process evaluation involving clinicians of the STD clinics was positive. At month 6, 36.0 % of the circumcised participants used condom less frequently with their regular sex partner. We recommend scaling up the intervention, taking prevention of risk compensation into account.

Assessment of Different Intervention Models of Male Circumcision and Their Preliminary Effectiveness in Reducing HIV Incidence Among Drug Users in Western China

World Health Organization (WHO) and Joint United Nations Program on AIDS (UNAIDS) recommend male circumcision (MC) as an additional HIV prevention measure. This study aimed to assess three models of promoting MC and their effects on preventing HIV infection among drug users in western China. We carried out a cohort study in three provinces of western China. HIV seronegative male drug users were recruited from methadone maintenance therapy clinics and cluster randomized into three intervention models. At baseline, 6, and 9 months of follow-up, changes in MC knowledge, the acceptability of MC, MC surgery uptake, and the costs of model implementation were analyzed. Of 1,304 male drug users who were screened, 1,218 were enrolled in the study. The participants' knowledge about MC was significantly increased after interventions by all three models. The one-stage model led to the highest increase in MC acceptability and the greatest increase in MC uptake. Multivariable Cox regression analysis showed that the one-stage model was also the most effective method to promote MC uptake, compared with the two-stage model [rate ratio (RR) = 0.602; 95% confidence interval (CI), 0.420-0.862] and three-stage model (RR = 0.555; 95% CI, 0.382-0.807). The HIV incidence rate in the MC group was lower than that in the non-MC group (RR = 0.234; 95% CI, 0.056-0.974). Moreover, the one-stage model required the lowest cost per circumcision. The one-stage model is the most effective and the most cost-effective intervention to increase MC uptake among male drug users in western China and could decrease the HIV incidence rate, based on a short follow-up investigation.
