What Prevents Central Asian Migrant Workers from Accessing HIV Testing? Implications for Increasing HIV Testing Uptake in Kazakhstan

Access Barriers to Healthcare for Undocumented Migrants in Low- and Middle-Income Countries: A Qualitative Systematic Review

This review aimed to examine the barriers to accessing health systems among undocumented migrants in low- and middle-income countries (LMICs). This qualitative review study was conducted to answer the question: 'What are the tangible and intangible barriers undocumented migrants face in accessing health systems in LMICs?'. Thirty-one studies published in English, Portuguese or Spanish between 2013 and 2023 were included. As a growing body of evidence demonstrates, undocumented migrants are among the most vulnerable populations with access to healthcare services impacted by high costs, legal barriers, document requirements and unclear policy messages. This review found that these barriers are interrelated and complicated by individual and institutional discrimination, xenophobia, and perceptions that undocumented migrants are less deserving and compete for local resources. Delayed care and limited primary healthcare access with critical health consequences were described in all such cases. The review suggests that barriers to healthcare access result from the intersection of outdated legislation, economic factors, weak health systems and service provision, bureaucratic inefficiencies and cultural norms and values. As such, improving access to care for undocumented migrants require intersectoral action and policy change that needs to be guided by context-sensitive research.

A digital citizen science intervention to reduce HIV stigma and promote HIV testing: a randomized clinical trial among adolescents and young adults in Kazakhstan

Background Kazakhstan has a high HIV incidence among adolescents and young adults (AYA), and high HIV stigma contributing to low HIV testing uptake. We examined whether an AYA-developed digital crowdsourced intervention reduced HIV stigma compared with conventional public health materials among AYA in Almaty, Kazakhstan. Methods A total of 216 AYA (females:116/males:110) aged 16-24 years were recruited to the online study cohort and randomized 1:1 to the intervention or control arm. AYA were exposed to the crowdsourced intervention or control materials once a week for 5weeks, with equivalent exposures between arms. Outcomes included a total HIV stigma score assessed at baseline, immediately post-intervention and 2months post-intervention from January to August 2023. We conducted multilevel mixed models to compare changes over time by arm and sex. Results AYA in the intervention arm had significantly lower HIV testing stigma 2months post-intervention (adjusted mean change (AMC): -0.73 (-1.07, -0.39)) than AYA in the control arm (AMC: -0.06 (-0.42, 0.30); P =0.032). Female AYA in the intervention arm had significantly lower total HIV stigma immediately post-intervention (AMC: -4.91 (-7.25, -2.58)) and 2months post-intervention (AMC: -5.16 (-7.48, -2.84)) than females in the control arm (immediately post-intervention AMC: -0.03 (-2.63, 2.57) and 2-months post-intervention AMC: -0.07 (-2.70, 2.56); P =0.012, P =0.012). Conclusions The AYA-developed crowdsourced intervention decreased HIV testing stigma, although this effect was moderated by sex, and decreased total HIV stigma among female AYA. Crowdsourced interventions may be a promising way to engage communities to develop interventions to decrease HIV stigma.

Inclusion of Labor Migrants as a Potential Key Population for HIV: A Nationwide Study from Tajikistan

Key populations are particularly vulnerable to human immunodeficiency virus (HIV) infection. Nearly half of Tajikistan's gross domestic product (GDP) originates from labor migrant transfers. While not officially designated as a key population, over 300,000 migrants return to Tajikistan every year at increased risk for HIV due to absence or interruption of treatment, change in risky behaviors, and other factors. We analyzed cross-sectional data from the national registry system operated by the Tajikistan Ministry of Health and Social Protection of individuals (n = 10,700) who had been diagnosed with HIV from 1 January 2010 to 30 May 2023. Individual HIV cases resided in five regions: Districts of Republican Subordination (DRS), Dushanbe (Tajikistan's capital city), Gorno-Badakhshan Autonomous Oblast (GBAO), Khatlon, and Sughd. We developed logistic regression models to investigate the relationships between key population status and demographic characteristics. GBAO has the largest proportion of labor migrants (49.59%), which is much larger than that of the other regions (<32%). In contrast to other key populations, there was a larger proportion of HIV cases in rural areas that were labor migrants (23.25%) in comparison to urban areas (16.05%). In multivariable analysis, the odds of being a labor migrant were 6.248 (95% CI: 4.811, 8.113), 2.691 (95% CI: 2.275, 3.184), and 1.388 (95% CI: 1.155, 1.668) times larger if a case was residing in GBAO, Sughd, or DRS, compared to Dushanbe, respectively. Our research contributes to the field by proposing to expand the definition of key population to include labor migrants in Central Asia who should be emphasized as a vulnerable population at high risk of HIV. We encourage policy action to provide designated HIV funding for labor migrants, increase international attention, and promote potential modifications of national regulations and/or laws regarding prevention and treatment of HIV among non-citizen populations.

Longitudinal analysis of lifestyle risk factors, nutrition status and drivers of food choice among urban migrants in Ulaanbaatar, Mongolia, and Almaty, Kazakhstan: a formative study

OBJECTIVE

To quantify and compare concurrent within-person trends in lifestyle risks, nutrition status and drivers of food choice among urban migrants in Central Asia.

DESIGN

We collected panel data on household structure, drivers of food choice, nutrition knowledge and diverse measures of nutrition status and lifestyle risk from urban migrants at 0, 3, 6 and 9 months using harmonised methodology in two cities. Trends were analysed using mixed-effects models and qualitatively compared within and between cities.

SETTING

Ulaanbaatar, Mongolia, and Almaty, Kazakhstan.

PARTICIPANTS

200 adults (22-55 years) who migrated to these cities within the past 2 years.

RESULTS

Adjusting for age and sex, each month since migration was positively associated with fasting TAG in Almaty (0·55 mg/dl; 95 % CI: 0·13, 0·94) and BMI (0·04 kg/m2; 95 % CI: 0·01, 0·07), body fat (0·14 %; 95 % CI: 0·01, 0·26) and fasting glucose (0·04 mmol/l; 95 % CI: 0·02, 0·05) and lipids in Ulaanbaatar (P < 0·05). In Almaty, nutrition knowledge (measured using an objective 20-point scale) declined despite improvements in diet quality (measured by Prime Diet Quality Score). The influence of food availability, price and taste on food choice increased in Almaty (P < 0·05). Upon multivariable adjustment, nutrition knowledge was positively associated with diet quality in Almaty and adherence to 'acculturated' diet patterns in both cities (P < 0·05). Different trends in smoking, sleep quality and generalised anxiety were observed between cities.

CONCLUSIONS

Findings indicate heterogeneous shifts in nutrition, lifestyles and drivers of food choice among urban migrants in Central Asia and provide an evidence base for focused research and advocacy to promote healthy diets and enable nutrition-sensitive food environments.

A citizen science approach to develop a digital intervention to reduce HIV stigma and promote HIV self-testing among adolescents and young adults: a mixed methods analysis from Kazakhstan

INTRODUCTION

Kazakhstan has one of the fastest-growing HIV epidemics in the world, with increasing rates among adolescents and young adults (AYA). Innovative strategies are needed to increase HIV testing uptake and decrease HIV stigma among AYA. Citizen science, defined as the active engagement of the general public in scientific research tasks, promotes and facilitates community engagement throughout the research process. This citizen science study used crowdsourcing to engage AYA in Kazakhstan to develop a digital intervention to reduce HIV stigma and promote HIV self-testing. Our objectives in this paper are to describe the approach used, its feasibility and acceptability, and AYA motivations for and lessons learned collaborating on the study.

METHODS

From October 2021 to July 2022, in collaboration with a Community Collaborative Research Board and a Youth Advisory Board, we developed an open call requesting multimedia submissions to reduce HIV testing stigma. Eligible submissions were separated by age group (13-19 or 20-29 years) and judged by a panel composed of AYA (n = 23), healthcare professionals (n = 12), and representatives from the local government and non-governmental organizations (n = 17). Each entry was reviewed by at least four judges and ranked on a 5-point scale. The top 20 open call contestants were asked to submit self-recordings sharing their motivation for and experience participating in the contest and lessons learned. Descriptive statistics were calculated for quantitative data. Qualitative data were coded using open coding.

RESULTS

We received 96 submissions from 77 youth across Kazakhstan. Roughly, three-quarters (n = 75/96) of entries met judging eligibility criteria. Of the eligible entries, over half (n = 39/75) scored 3.5 or higher on a 5-point scale (70.0%). The most frequent types of entries were video (n = 36/96, 37.5%), image (n = 28/96, 29.2%) and text (n = 24/96, 25.0%). AYA's primary motivations for collaborating on the study included a desire to improve society and help youth. The main challenges included creating content to address complex information using simple language, finding reliable information online and technological limitations.

CONCLUSIONS

Crowdsourcing was feasible and highly acceptable among AYA in Kazakhstan. Citizen science approaches hold great promise for addressing the increasingly complex health and social challenges facing communities today.

Factors impacting HIV testing among young sexually active women migrant workers in Vietnamese industrial zones

BACKGROUND

Young migrant workers living in low- and middle-income countries often experience barriers and inadequate access to HIV prevention and treatment services. This study examines the prevalence of HIV testing, associated factors, and reasons for obtaining and not obtaining HIV testing among young sexually active women migrant workers in an industrial zone in Hanoi, Vietnam.

METHODS

A cross-sectional study was conducted among 512 sexually active young women migrant workers (aged 18 to 29) working in the Thang Long industrial zone in Hanoi, Vietnam. Data was collected via a face-to-face interview from January 2020 to June 2021. Multivariable logistic regression analysis was used to explore factors associated with ever-testing for HIV among sexually active participants.

RESULTS

The study found a low level of HIV testing and high rates of unprotected sex. Among those who reported being sexually active, only 23.7% of participants (n = 126) reported having ever been tested for HIV. Among those who reported never having tested for HIV, 38.2% reported not using condoms during their most recent sexual encounter. Factors associated with engaging in HIV testing included being older (25-29 years), having greater knowledge about HIV, past use of sexual and reproductive health and HIV services, and familiarity with HIV testing locations.

CONCLUSIONS

Overall, a low level of HIV testing, high rates of unprotected sex, and low perceived risks regarding HIV among the study participants point to a need to implement targeted HIV interventions that can improve both safe sex practices and perceptions of and knowledge about risky sexual behaviors. Such interventions should use insights from this study to address factors facilitating HIV testing among industrial zones' women migrant workers.

Re-validation and cultural adaptation of the brief, standardized assessment tool for measuring HIV-related stigma in healthcare settings in Almaty, Kazakhstan

The HIV epidemic continues to grow in Kazakhstan and HIV stigma remains a major barrier to HIV prevention and treatment in the country. HIV stigma in healthcare setting may also discourage people living with HIV (PLHIV) from getting the care needed. Therefore, studying the attitudes of healthcare workers towards PLHIV is important and requires well-constructed measurement tools adapted to the specific cultural context. In our study, we aimed to adapt and re-validate a brief questionnaire on HIV stigma among healthcare workers in Almaty, Kazakhstan. We held focus group discussions to obtain input on an existing questionnaire and surveyed 448 primary healthcare providers to psychometrically evaluate the scale. The final HIV-stigma scale consisted of 15 items, 6 of them measuring negative opinions about PLHIV and the rest assessing stigmatizing health facility policies towards PLHIV. Both HIV-stigma subscales demons6trated adequate psychometric properties (with Cronbach's alpha α = 0.57 for the first and α = 0.86 for the second subscale, and with factor loadings >0.35 within each subscale). High numbers of respondents holding negative attitudes towards PLHIV, detected in this sample (87%; n = 380), may suggest the need for immediate actions addressing HIV stigma in healthcare in Kazakhstan.

Predictors for HIV testing among Chinese workers in infrastructure construction enterprises in Kenya

BACKGROUND

There are increasing Chinese migrants in sub-Saharan Africa currently. Most of them are engaged in infrastructure construction. Research has shown that they stay at particular risk of HIV and are recommended for HIV testing. However, their HIV testing behavior, and its relevant factors, have not been researched among them by now. This study describes the recent HIV testing behavior and relevant factors among Chinese migrant workers in Kenya.

METHODS

A cross-sectional survey was conducted among 110 male Chinese workers from six different Chinese infrastructure construction enterprises in Kenya. Furthermore, a two-stage cluster random sampling method was used to select participants. We used a questionnaire that included HIV testing history, demographic characteristics, and putative multilevel facilitators of HIV testing. Logistic regression was used to explore the predictors of recent HIV testing behavior among Chinese migrant workers in Kenya.

RESULT

Of the 110 participants, 30 (27.27%) were tested for HIV in the recent year. All participants were male, and the majority were married (73.2%). The mean age was 37.49 years (SD = 9.73; range: 23 to 63), and a considerable proportion refused to answer questions about transactional sexual behaviors in the last year. Most were able to obtain HIV-related information (91.8%) and were exposed to HIV-related information in the last year (68.2%), but only 47.6% had sufficient HIV knowledge. Nearly one-fifth of them believed that selling sex and paying for sex is acceptable. Multiple logistic regression analysis indicated that participants who could accept the 'pay for sex' (OR: 2.74; 95% CI: 1.02, 7.36) and exposed to HIV related information (OR: 4.75; 95% CI: 1.29, 17.44) were more likely to test for HIV in the recent 1 year.

CONCLUSION

Higher current HIV test rates were associated with a more open sexual attitude towards paying for sex and being exposed to HIV-related information in the last year among Chinese workers in Kenya. More specific attention to HIV should be attached to this population to increase the rate of HIV testing among them.

Legal status as a life course determinant of health: parent status, adjudication stages, and HIV knowledge among highlanders in Thailand

BACKGROUND

Rising nativism and political volatility worldwide threaten to undermine hard-won achievements in human rights and public health. Risks are particularly acute for hundreds of millions of migrants, minorities, and Indigenous peoples, who face disproportionately high health burdens, including HIV/AIDS, and precarious legal status (LS). While LS is receiving increasing attention as a social determinant of health and HIV, understandings are still limited to select immigrant communities. Its effects on health among stateless communities, particularly in the Global South, remain largely unknown. Moreover, widespread limitations in census measures of LS reduce its complexity to a simplistic citizen/non-citizen binary or insufficient proxies. Thailand's ethnolinguistically diverse highlander population experiences disproportionately high HIV prevalence and comprises one of the world's largest and most protracted cases of statelessness, an acute condition of precarious LS. As such, analysis of LS and health outcomes among highlanders is both critically warranted, and useful as a case study outside of the migration paradigm.

METHODS

Drawing on the UNESCO Highland Peoples Survey II (2010), an unprecedented and unique cross-sectional census of highlanders in Thailand, we mobilize complex measures of LS in adjusted ordinal logistic regression models to assess how parent citizenship and LS adjudication over the early life course condition adult HIV knowledge-a key protective factor against transmission (n = 8079).

RESULTS

Adjusted ordinal logistic regression on knowledge scores reveal that parent citizenship predicts odds of greater knowledge by 1.4- to 2.2-fold, depending on ethnic group. This is partially explained by divergent stages of LS adjudication between birth and adulthood, including successful birth registration and adult citizenship acquisition, along with secondary school completion. Precisely how these factors contribute to HIV knowledge varies by ethnic group.

CONCLUSIONS

This study advances knowledge of LS outside of the migration paradigm, reveals heretofore unexamined connections between LS and access to public health information, and elucidates how instabilities in LS adjudication stages underlie health inequalities over the life course. Findings indicate that securing success in public health and human rights agendas requires attention to how states adjudicate and deploy LS in multiple stages across the life course to structure access and exclusion among migrant and non-migrant communities alike.

Gaps in the HIV diagnosis and care cascade for migrants in Australia, 2013-2017: A cross-sectional study

BACKGROUND

Globally, few studies compare progress toward the Joint United Nations Program on HIV/AIDS (UNAIDS) Fast-Track targets among migrant populations. Fast-Track targets are aligned to the HIV diagnosis and care cascade and entail achieving 90-90-90 (90% of people living with HIV [PLHIV] diagnosed, 90% of those diagnosed on treatment, and 90% of those on treatment with viral suppression [VS]) by 2020 and 95-95-95 by 2030. We compared cascades between migrant and nonmigrant populations in Australia.

METHODS AND FINDINGS

We conducted a serial cross-sectional survey for HIV diagnosis and care cascades using modelling estimates for proportions diagnosed combined with a clinical database for proportions on treatment and VS between 2013-2017. We estimated the number of PLHIV and number diagnosed using New South Wales (NSW) and Victorian (VIC) data from the Australian National HIV Registry. Cascades were stratified by migration status, sex, HIV exposure, and eligibility for subsidised healthcare in Australia (reciprocal healthcare agreement [RHCA]). We found that in 2017, 17,760 PLHIV were estimated in NSW and VIC, and 90% of them were males. In total, 90% of estimated PLHIV were diagnosed. Of the 9,391 who were diagnosed and retained in care, most (85%; n = 8,015) were males. We excluded 38% of PLHIV with missing data for country of birth, and 41% (n = 2,408) of eligible retained PLHIV were migrants. Most migrants were from Southeast Asia (SEA; 28%), northern Europe (12%), and eastern Asia (11%). Most of the migrants and nonmigrants were males (72% and 83%, respectively). We found that among those retained in care, 90% were on antiretroviral therapy (ART), and 95% of those on ART had VS (i.e., 90-90-95). Migrants had larger gaps in their HIV diagnosis and care cascade (85-85-93) compared with nonmigrants (94-90-96). Similarly, there were larger gaps among migrants reporting male-to-male HIV exposure (84-83-93) compared with nonmigrants reporting male-to-male HIV exposure (96-92-96). Large gaps were also found among migrants from SEA (72-87-93) and sub-Saharan Africa (SSA; 89-93-91). Migrants from countries ineligible for RHCA had lower cascade estimates (83-85-92) than RHCA-eligible migrants (96-86-95). Trends in the HIV diagnosis and care cascades improved over time (2013 and 2017). However, there was no significant increase in ART coverage among migrant females (incidence rate ratio [IRR]: 1.03; 95% CI 0.99-1.08; p = 0.154), nonmigrant females (IRR: 1.01; 95% CI 0.95-1.07; p = 0.71), and migrants from SEA (IRR: 1.03; 95% CI 0.99-1.07; p = 0.06) and SSA (IRR: 1.03; 95% CI 0.99-1.08; p = 0.11). Additionally, there was no significant increase in VS among migrants reporting male-to-male HIV exposure (IRR: 1.02; 95% CI 0.99-1.04; p = 0.08). The major limitation of our study was a high proportion of individuals missing data for country of birth, thereby limiting migrant status categorisation. Additionally, we used a cross-sectional instead of a longitudinal study design to develop the cascades and used the number retained as opposed to using all individuals diagnosed to calculate the proportions on ART.

CONCLUSIONS

HIV diagnosis and care cascades improved overall between 2013 and 2017 in NSW and VIC. Cascades for migrants had larger gaps compared with nonmigrants, particularly among key migrant populations. Tracking subpopulation cascades enables gaps to be identified and addressed early to facilitate achievement of Fast-Track targets.

Barriers and Facilitators of Rapid HIV and Syphilis Testing Uptake Among Filipino Transnational Migrants in China

Transnational migrant workers are known to be at high risk for HIV/STIs. This study estimated the point prevalence of HIV/syphilis and examined correlates of HIV/syphilis testing uptake among female migrant domestic workers in Macao, China. Data was obtained from 1363 female Filipino domestic workers who were offered free rapid HIV and syphilis testing. A mixed methods analysis was undertaken to examine correlates of testing and themes about reasons for not testing. Among 1164 women tested, there were no cases of HIV/syphilis observed and 199 (14.6%) refused HIV/syphilis testing. Greater social integration (aOR 1.12; 95% CI 1.02-1.24), having more than one sexual partner (aOR 1.65; 95% CI 1.02-2.65), and longer working hours on the testing day (aOR 0.97; 95% CI 0.94-1.00), were associated with testing uptake. Among those who tested, the majority (> 70%) had never tested before, suggesting the need to improve testing outreach. Qualitative themes about reasons for not testing included low perceived need and insufficient time. Individual and structural testing barriers should be reduced to optimize HIV/STI testing in migrant populations.

Migrant Workers and Their Occupational Health and Safety

In 2015, approximately 244 million people were transnational migrants, approximately half of whom were workers, often engaged in jobs that are hazardous to their health. They work for less pay, for longer hours, and in worse conditions than do nonmigrants and are often subject to human rights violations, abuse, human trafficking, and violence. Worldwide, immigrant workers have higher rates of adverse occupational exposures and working conditions, which lead to poor health outcomes, workplace injuries, and occupational fatalities. Health disparities of immigrant workers are related to environmental and occupational exposures and are a result of language/cultural barriers, access to health care, documentation status, and the political climate of the host country. Recommendations on global and local scales are offered as potential solutions to improving the health of immigrant workers.
