Can social support mediate stigma and perceived stress in people live with human immunodeficiency virus?

Stigma has heavily impacted People Living with HIV (PLWH). Limited studies report on how social support affects HIV-related stigma and perceived stress, especially in Myanmar. During first seven months of 2020, a random sample of 248 eligible PLWH were contacted from a private, closed Facebook group with more than 18,000 Myanmar people, where 90% of the members were PLWH. Variables collected included demographics data, perceived stress, social support, and HIV stigma. After controlling for the effects of demographic variables, the path from HIV stigma to perceived stress (direct effect ß = 0.40) and though the mediation of social support was significant (indirect effect ß = 0.014). However, the mediating effect of social support was non-significant between HIV stigma and perceived stress. This exploratory study shows that social support did not have the expected effect of decreasing perceived stress in PLWH in Myanmar. Interventions to reduce HIV stigma to decrease perceived stress should consider other strategies, e.g., spirituality-based practice, to reduce perceived stress in Myanmar PLWH.

Antiretroviral therapy (ART) coverage at public and private ART facilities in Myanmar.

Myanmar's continuum of HIV care was surveyed to assess the National AIDS Control Programme's progress; according to its reports, ART coverage was 38% in 2014, 47% in 2015, and 56% in 2016. To evaluate ART coverage and gaps in care, a serial cross-sectional study used the national programme data reported between January 2014 and December 2016, including 228 public and 62 private ART facilities. ART coverage among PLHIV under 15 years old was 89% in 2014, 93% in 2015, and 88% in 2016. Retention in ART care among women was higher than among men, although women were more likely to discontinue care. PLHIV who were enrolled in ART facilities initiated ART at the rates of 60% in 2014, 68% in 2015, and 74% in 2016. Over the 3-year study period, these facilities reported that 2.5-3.7% of PLHIV taking ART had died, and that 3.3-4.8% were lost to follow-up. PLHIV who were tested for viral load were low (2.5-3%). The continuum of HIV care at ART facilities has improved, but more information about attrition and viral suppression are still needed. The reporting system for newly diagnosed PLHIV and facilities for viral load testing need to be strengthened.

Adaptation and validation of a culturally adapted HIV stigma scale in Myanmar.

BACKGROUND: HIV stigma is a common barrier to HIV prevention, testing, and treatment adherence, especially for low- and middle-income countries such as Myanmar. However, there was no validated Myanmar version of a stigma scale. Therefore, we adapted the English version of the 40-item Berger's HIV stigma scale and the 7-item Indian HIV stigma scale into a 47-item Myanmar HIV stigma scale and then evaluated the scale's psychometric properties. METHOD: From January 2020 to May 2020, using random sampling methods, 216 eligible Myanmar people living with HIV/AIDS (PLWHA) were contacted from a closed Facebook group that included more than 10,000 PLWHA. A sample of 156 Myanmar PLWHA completed the online self-reported survey. RESULTS: A six-factor structure for the scale was determined through exploratory factor analysis, explaining 68.23% of the total variance. After deleting 12 items, the 35-item HIV stigma scale achieved Cronbach 's α of 0.72 to 0.95. Construct validity of the scale was demonstrated by significant association with self-reported depression and social support levels (r = 0.60, and - 0.77, p < 0.01). In Rasch analysis, the scale achieved person reliability of 3.40 and 1.53 and a separation index of 0.92 and 0.70. The infit and outfit mean squares for each item ranged from 0.68 to 1.40. No differential item functioning across gender or educational level was found. CONCLUSIONS: The psychometric properties of the 35-item Myanmar version of the HIV stigma scale support it as a measure of stigma among PLWHA in Myanmar. This instrument could help healthcare providers to better understand how stigma operates in PLWHA and to develop tailored stigma-reduction interventions in Myanmar.

Preventive chemotherapy reverses covert, lymphatic-associated tissue change in young people with lymphatic filariasis in Myanmar.

OBJECTIVES: This longitudinal comparative study investigated the effect of preventive chemotherapy (PC) on covert tissue changes associated with lymphatic filariasis (LF) among young people living in an LF-endemic area in Myanmar. METHODS: Tissue compressibility and extracellular free fluid in the lower limbs of people aged 10-21 years were measured using indurometry and bioimpedance spectroscopy (BIS). Baseline measures were taken in October 2014, annual mass drug administration (MDA) of PC was delivered in December, and in March 2015 further PC was offered to LF-positive cases who had missed MDA. Follow-up measures were taken in February and June 2015. RESULTS: A total of 50 antigen-positive cases and 46 antigen-negative controls were included. Self-reported PC consumption was 60.1% during 2014 MDA and 66.2% overall. At second follow-up, 24 of 34 cases and 27 of 43 controls had consumed PC. Significant and clinically relevant between-group differences at baseline were not found post-PC. Bayesian linear mixed models showed a significant change in indurometer scores at both calves for antigen-positive cases who consumed any PC (dominant calf: -0.30 [95% CI -0.52, -0.07], P < 0.05 and non-dominant calf: -0.35 [95% CI -0.58, -0.12], P < 0.01). Changes in antigen-negative participants or those not consuming PC were not significant. CONCLUSION: This study is the first attempt to use simple field-friendly tools to track fluid and tissue changes after treatment of asymptomatic people infected with LF. Results suggested that PC alone is sufficient to reverse covert lymphatic disturbance. Longer follow-up of larger cohorts is required to confirm these improvements and whether they persist over time. These findings should prompt increased efforts to overcome low PC coverage, which misses many infected young people, particularly males, who are unaware of their infection status, unmotivated to take PC and at risk of developing lymphoedema. Indurometry and BIS should be considered in assessment of lymphatic filariasis-related lymphedema.

OBJECTIFS: Cette étude comparative longitudinale a investigué l'effet de la chimiothérapie préventive (CP) sur les modifications tissulaires cachées associées à la filariose lymphatique (FL) chez les jeunes vivant dans une zone d'endémie pour la FL au Myanmar. MÉTHODES: La compressibilité des tissus et le liquide libre extracellulaire dans les membres inférieurs des personnes âgées de 10 à 21 ans ont été mesurés par indurométrie et spectroscopie de bioimpédance (BIS). Les mesures de base ont été prises en octobre 2014, la distribution en masse de médicament (DMM) annuelle a été administrée en décembre et en mars 2015, et une CP additionnelle a été offerte aux cas positifs pour la FL qui avaient manqué la DMM. Des mesures de suivi ont été prises en février et juin 2015. RÉSULTATS: 50 cas positifs pour l'antigène et 46 témoins négatifs ont été inclus. L'administration de CP auto-déclarée était de 60,1% durant la DMM de 2014 et de 66,2% au total. Au deuxième suivi, 24 des 34 cas et 27 des 43 témoins avaient pris la CP. Des différences significatives et cliniquement pertinentes entre les groupes au départ n'ont pas été trouvées après la CP. Les modèles mixtes linéaires bayésiens ont montré un changement significatif des scores d'indurometrie aux deux mollets pour les cas positifs pour l'antigène qui prenaient une CP (mollet dominant: -0,30 [IC95%: -0,52, -0,07], p <0,05, mollet non dominant: - 0,35 [IC95%: -0,58, -0,12], p <0,01). Les changements chez les participants négatifs pour l'antigène ou ceux qui ne prenaient pas de CP n'étaient pas significatifs. CONCLUSION: Cette étude est la première tentative d'utilisation d'outils simples, conviviaux sur le terrain, pour suivre les modifications du tissu conjonctif après le traitement de personnes asymptomatiques infectées par la FL. Les résultats suggèrent que la CP seule est suffisante pour inverser les modifications lymphatiques cachées. Un suivi plus long de plus grandes cohortes est nécessaire pour confirmer ces améliorations et déterminer si elles persistent ou non. Ces résultats devraient inciter à redoubler d'efforts pour surmonter la faible couverture en CP, qui rate beaucoup de jeunes infectés, en particulier les hommes, qui ne sont pas au courant de leur statut d'infection, qui ne sont pas motivés pour prendre une CP et risquent de développer un lymphœdème. L'indurométrie et la BIS devraient être considérées dans l'évaluation du lymphoedème associé à la filariose lymphatique.

Adaptation and Validation of the Cognitive and Affective Mindfulness Scale-Revised (CAMS-R) in People Living with HIV in Myanmar.

Objectives: Valid and reliable instruments for the measurement of mindfulness are crucial for people living with HIV. However, there was no Myanmar version of such an instrument. Methods: We adapted the English version of the 12-item Cognitive and Affective Mindfulness Scale-Revised (CAMS-R) based on standard cross-cultural procedures. By randomly sampling methods, a sample of 248 eligible people living with HIV was contacted from a closed Myanmar Facebook group; 159 PLHIV completed the initial 12-item version of the adapted survey. Results: Three items were removed due to low item-to-total correlations of the corrected item-total correlation as well as having infit and outfit mean squares outside the range of 0.6 to 1.4. After deleting the 3 items, the three-factor structure was confirmed by confirmatory factor analysis, which indicated good model fit. The resultant 9-item CAMS-R in Myanmar (CAMS-R-M-2) achieved good internal reliability (Cronbach's α of 0.75 to 0.87, and the corrected item-total correlation ranged from 0.44 to 0.81). Construct validity of the scale was demonstrated by significant association with self-reported HIV stigma and social support levels (r = 0.63, and - 0.53). In Rasch analysis, the infit and outfit mean squares for each item ranged from 0.49 to 1.24, and the person reliability was 2.17 and the separation index was 0.83. Conclusions: The 9-item CAMS-R-M-2 with a three-factor structure has good reliability and validity. Higher total scores and subscale score reflected greater mindfulness qualities in people living with HIV in Myanmar.

The Mediating Effects of Mindfulness on Perceived Stress From HIV Stigma in People Living With HIV in Myanmar: A Cross-sectional Study.

ABSTRACT: HIV is a highly stigmatized and stressful condition for people with HIV (PWH). As a country heavily influenced by religion, especially Buddhism, we explore how the perceived stress from HIV stigma interacts with the mediator of mindfulness on PWH in Myanmar. From January to July 2020, a sample of 248 eligible PWH was recruited by quasi-random sampling methods from a private Facebook group in Myanmar. Data on demographics, HIV stigma, mindfulness, and perceived stress were collected. The bias-corrected percentile bootstrap method was used to test multiple mediation analyses. The path from perceived HIV stigma to perceived stress (direct effect ß = 0.16) and the mediating effect of mindfulness on that stress were significant (indirect effect accounts for 45.15% of total effect). The findings indicate that interventions enhancing mindfulness-based practice should be considered to reduce HIV stigma and, therefore, lower perceived stress among PWH in Myanmar.

Translation, Adaption, and Psychometric Testing of the Myanmar Version of the Medical Outcomes Study Social Support Survey for People Living With HIV/AIDS.

Introduction: Valid and reliable instruments are crucial for measuring perceived social support among people living with HIV (PLHIV). We aimed to investigate the psychometric properties of the English version of the 19-item Medical Outcomes Study Social Support Survey (MOS-SSS) adapted for PLHIV in Myanmar. Methods: Based on a standard cross-cultural procedure, we adapted the MOS-SSS and formed a Myanmar version of the scale (MOS-SSS-M), and then tested its validity and reliability. A sample of 250 eligible PLHIV was collected from a closed Facebook group that included more than 10,000 Myanmars, most of whom were PLHIV. Results: The MOS-SSS-M achieved a Cronbach's α of 0.82-0.95. Confirmatory factor analysis revealed an acceptable fit index for the four-factor structure. Construct validity was demonstrated by significant association with self-reported HIV stigma and stress levels, and further confirmed by the findings of Rasch analysis. Conclusion: The MOS-SSS-M with a four-factor structure can be used to measure the level and categories of perceived social support among PLHIV in Myanmar.

Risk factors for lymphatic filariasis and mass drug administration non-participation in Mandalay Region, Myanmar.

BACKGROUND: Myanmar commenced a lymphatic filariasis (LF) elimination programme in 2000. Whilst the country has made considerable progress since then, a number of districts have demonstrated persistent transmission after many rounds of mass drug administration (MDA). The causes of unsuccessful MDA have been examined elsewhere; however, there remains little information on the factors that contribute in Myanmar. METHODS: We conducted an analysis of factors associated with persistent infection, LF-related hydrocoele and MDA participation in an area with ongoing transmission in 2015. A cross-sectional household survey was undertaken in 24 villages across four townships of Mandalay Region. Participants were screened for circulating filarial antigen (CFA) using immunochromatographic tests and, if positive, for microfilaria by night-time thick blood slide. Individuals 15 year and older were assessed for filariasis morbidity (lymphoedema and, if male, hydrocoele) by ultrasound-assisted clinical examination. A pre-coded questionnaire was used to assess risk factors for LF and for non-participation (never taking MDA). Significant variables identified in univariate analyses were included in separate step-wise multivariate logistic regressions for each outcome. RESULTS: After adjustment for covariates and survey design, being CFA positive was significantly associated with age [odds ratio (OR) 1.03, 95% CI 1.01-1.06), per year], male gender (OR 3.14, 1.27-7.76), elevation (OR 0.96, 0.94-0.99, per metre) and the density of people per household room (OR 1.59, 1.31-1.92). LF-related hydrocoele was associated with age (OR 1.06, 1.03-1.09, per year) and residing in Amarapura Township (OR 8.93, 1.37-58.32). Never taking MDA was associated with male gender [OR 6.89 (2.13-22.28)] and age, particularly in females, with a significant interaction term. Overall, compared to those aged 30-44 years, the proportion never taking MDA was higher in all age groups (OR highest in those < 5 years and > 60 years, ranging from 3.37 to 12.82). Never taking MDA was also associated with residing in Amarapura township (OR 2.48, 1.15-5.31), moving to one's current village from another (OR 2.62, 1.12-6.11) and ever having declined medication (OR 11.82, 4.25-32.91). Decreased likelihood of never taking MDA was associated with a higher proportion of household members being present during the last MDA round (OR 0.16, 0.03-0.74) and the number visits by the MDA programme (OR 0.69, 0.48-1.00). CONCLUSIONS: These results contribute to the understanding of LF and MDA participation-related risk factors and will assist Myanmar to improve its elimination and morbidity management programmes.

HIV Care Cascade among Prisoners of the Mandalay Central Prison in Myanmar: 2011-2018.

Prisoners have a higher HIV prevalence and higher rates of attrition from care as compared with the general population. There is no published evidence on this issue from Myanmar. We assessed (1) HIV test uptake, HIV positivity, and enrollment in care among newly admitted prisoners between 2017 and 18 (2) Treatment outcomes among HIV-positive prisoners enrolled in care between 2011 and 18. This was a cohort study involving secondary analysis of program data. Among 26,767 prisoners admitted to the Mandalay Central Prison between 2017 and 2018, 10,421 (39%) were HIV-tested, 547 (5%) were HIV-positive, and 376 (69%) were enrolled in care. Among the 1288 HIV-positive prisoners enrolled in care between 2011 and 2018, 1178 (92%) were started on antiretroviral therapy. A total of 883 (69%) were transferred out (post-release) to other health facilities, and among these, only 369 (42%) reached their destination health facilities. The final outcomes (censored on 30 June 2019) included the following: (i) Alive and in care 495 (38%), (ii) death 138 (11%), (iii) loss to follow-up 596 (46%), and (iv) transferred out after reaching the health facilities 59 (5%). We found major gaps at every step of the HIV care cascade among prisoners, both inside and outside the prison. Future research should focus on understanding the reasons for these gaps and designing appropriate interventions to fill these gaps.

The prevalence of lymphatic filariasis infection and disease following six rounds of mass drug administration in Mandalay Region, Myanmar.

Lymphatic filariasis is widely endemic in Myanmar. Despite the establishment of an elimination program in 2000, knowledge of the remaining burden of disease relies predominantly on programmatic information. To assist the program, we conducted an independent cross-sectional household cluster survey to determine the prevalence of filariasis infection, morbidity and mass-drug administration coverage in four townships of the Mandalay Region: Amarapura, Patheingyi, Tada-U and Wundwin. The survey included 1014 individuals from 430 randomly selected households in 24 villages. Household members one year and older were assessed for antigenaemia using immunochromatographic test cards and if positive, microfilaraemia by night-time thick blood smear. Participants 15 years and older were assessed for filariasis morbidity by ultrasound-assisted clinical examination. The overall prevalence of infection was 2.63% by antigenaemia (95% confidence interval (CI) 1.71-4.04%) and 1.03% by microfilaraemia (95%CI 0.59-1.47%). The prevalence of hydrocoele in adult males was 2.78% (95%CI 1.23-6.15%) and of lymphoedema in both genders was 0% (95%CI 0-0.45%). These results indicate the persistence of filarial infection and transmission despite six rounds of annual mass drug administration and highlight the need for further rounds as well as the implementation of morbidity management programs in the country.

Mapping and modelling the impact of mass drug adminstration on filariasis prevalence in Myanmar.

BACKGROUND: Lymphatic filariasis (LF) is endemic in Myanmar and targeted for elimination. To highlight the National Programme to Eliminate Lymphatic Filariasis (NPELF) progress between 2000 and 2014, this paper describes the geographical distribution of LF, the scale-up and impact of mass drug administration (MDA) implementation, and the first evidence of the decline in transmission in five districts. METHODS: The LF distribution was determined by mapping historical and baseline prevalence data collected by NPELF. Data on the MDA implementation, reported coverage rates and sentinel site surveillance were summarized. A statistical model was developed from the available prevalence data to predict prevalence at township level by year of measurement. Transmission assessment survey (TAS) methods, measuring antigenemia (Ag) prevalence in children, were used to determine whether prevalence was below a level where recrudescence is unlikely to occur. RESULTS: The highest baseline LF prevalence was found in the Central Valley region. The MDA implementation activities scaled up to cover 45 districts, representing the majority of the endemic population, with drug coverage rates ranging from 60.0% to 98.5%. Challenges related to drug supply and local conflict were reported, and interrupted MDA in some districts. Overall, significant reductions in LF prevalence were found, especially after the first 2 to 3 rounds of MDA, which was supported by the corresponding model. The TAS activities in five districts found only two Ag positive children, resulting in all districts passing the critical threshold. CONCLUSION: Overall, the Myanmar NPELF has made positive steps forward in the elimination of LF despite several challenges, however, it needs to maintain momentum, drawing on international stakeholder support, to aim towards the national and global goals of elimination.

Malaria profiles and challenges in artemisinin resistance containment in Myanmar.

BACKGROUND: This study examined evolving malaria profiles from January, 2010 to December, 2014 to evaluate achievements and challenges of implementing measures to prevent and control spread of artemisinin resistance in Myanmar. METHODS: Using National Malaria Control Programme (NMCP) data, a cross-sectional descriptive study of 52 townships in artemisinin-resistant containment areas in Myanmar was conducted. Annual program data were analysed, and trends over time are graphically presented. RESULTS: In the 52 study townships populated by 8.7 million inhabitants, malaria incidence showed a decreasing trend from 10.54 per 1 000 population in 2010 to 2.53 in 2014, and malaria mortalities also decreased from 1.83 per 100 000 population in 2010 to 0.17 in 2014. The proportion of confirmed to total tested malaria cases also decreased from 6 to 1%, while identification of cases improved. All cases from all parasites species, including Plasmodium falciparum, decreased. Coverage of LLIN (long-lasting insecticidal net)/ITN (insecticide-treated mosquito nets) and indoor residual spraying (IRS) was high in targeted areas with at-risk persons, even though the total population was not covered. In addition to passive case detection (PCD), active case detection (ACD) was conducted in hard-to-reach areas and worksites where mobile migrant populations were present. ACD improved in most areas from 2012 to 2014, but continues to need to be strengthened. CONCLUSIONS: The findings provide useful data on the malaria situation in artemisinin-resistant initiative areas, which may be useful for the NMCP to meet its elimination goal. These profiles could contribute to better planning, implementation, and evaluation of intervention activities.
