Antiretroviral therapy (ART) is a lifelong treatment. To date, ART adherence is suboptimal for most patients in resource-poor settings. Previous research indicates that medication side effects are perceived to be a significant barrier of high ART adherence. Data regarding the role of adherence self-efficacy in mediating the relationship between side effects from ART and adherence to ART are limited; thus, this study examines this potential mediational role of self-efficacy. A cross-sectional survey of 2987 people living with HIV aged ≥18 years was conducted in 2012–2013 in Guangxi Autonomous Region (Guangxi) which has one of the fastest-growing HIV rates in China. Of the total sample, 2146 (72.1%) participants had initiated ART. Participants reported the number of days of completing the daily dose of ART in the past month; adherence was defined as completing the daily dose at least 28 days in the last month (≥90%). Side effects were significantly negatively related to adherence to ART. Mediation analyses indicated that adherence self-efficacy significantly mediated the side effects–adherence relationship. Future interventions to increase adherence self-efficacy and effective coping with side effects among HIV patients are needed in order to improve their ART adherence.

Intimate partner violence is prevalent among female sex workers (FSWs) in China, and it is significantly associated with mental health problems among FSWs. However, limited studies have explored the mechanisms/process by which violence affects mental health. The purpose of this study was to explore the relationships among partner violence, internalized stigma, and mental health problems among FSWs. Data were collected using a self-administered cross-sectional survey administered to 1,022 FSWs in the Guangxi Zhuang Autonomous Region (Guangxi), China during 2008–2009. We used structural equation modeling to test the hypothesized relationships. Results indicated that violence perpetrated by either stable sexual partners or clients was directly and positively associated with mental health problems. Violence also had an indirect relation to mental health problems through stigma. Results highlight the need for interventions on counseling and care for FSWs who have experienced violence and for interventions to increase FSWs’ coping skills and empowerment strategies.

The prevalence of HIV and syphilis among middle and high-fee female sex workers (FSWs) has been widely reported but little is known among low-fee FSWs. This study aims to determine the prevalence and associated factors of HIV and syphilis among low-fee FSWs in China.

The COVID-19 pandemic has brought immense challenges on the health system including HIV care service. Based on online survey data of 1,029 HIV care providers in Guangxi, China, we assessed their perspectives on the challenges for HIV service delivery and perceived impacts of such challenges on patient care during the COVID-19 outbreak. Multivariate regression analysis was conducted to test the association between specific challenges and patient care outcomes controlling for socio-demographics of HIV care providers. The prominent impacts of COVID-19 on patient care outcomes included “not being able to make follow-up visits on time”, “not being able to get ARV refills timely”, and “compromised ART adherence”. Patient care outcome was significantly associated with “not being able to go to work due to quarantine and traffic restriction”, “no overall arrangement”, “no guideline for HIV service”, “conflicts between HIV care and response to COVID-19”, and “clinics were overwhelmed by COVID-19 care”. In response to dual epidemics of COVID-19 and HIV, policy makers may consider the potential impact of large-scale preventive strategies (e.g., lockdowns) on HIV care, assist healthcare providers to navigate shifting tasks and resetting priorities effectively, and develop clear guidelines and clinic-level arrangements to best serve both COVID-19 and HIV patients.

The current study examined whether gender, HIV-related stigma, social support, and the interaction between gender and social support are associated with coping responses among people living with HIV and AIDS (PLWHA) in Guangxi, China. A total of 2987 PLWHA in Guangxi participated from October 2012 to August 2013. Multivariate analysis of covariance was conducted with gender and social support as main factors in the model, and stigma and other variables as covariates. After controlling for demographic variables and stigma, there were significant main effects of emotional social support (F = 1.61, p < .001), functional social support (F = 1.67, p < .001), and informational social support (F = 3.67, p < .001) on various coping strategies. The interaction between gender and informational social support (F = 1.33, p < .05), internalized stigma (F = 37.03, p < .001) and perceived stigma (F = 9.16, p < .001) were associated with various coping strategies. Findings signify the importance of HIV-related stigma and social support differences in the coping strategies among PLWHA in Guangxi, China.

Global literature indicates the burden of human immunodeficiency virus (HIV), syphilis and hepatitis C virus (HCV) has disproportionately affected cross-border migrant female sex workers (FSW). However, few studies reported the HIV risk among Vietnamese FSW at borderline areas in China. We examined five consecutive years of HIV, syphilis, and HCV prevalence and corresponding risk factors among this group in Guangxi Province of China in the current study. Demographic and behavioral data as well as test results of blood samples for HIV/syphilis/HCV testing were collected from the annual National Sentinel Surveillance (NSS) from the year of 2010 to 2014. The prevalence trends were first examined by stratified demographic and behavioral status. Predictive models with logistic regression were further employed to identify risk predictors for HIV, syphilis and HCV combined with multiple imputation for missing data as well as restricted cubic splines for key continuous covariates. Moreover, weighted prevalence using the distribution of venue types among all FSW from the NSS survey as the standardized population was also reported. The overall prevalence of HIV, syphilis and HCV across the five year period was 3.2 % (95 % CI = 2.1 %,4.3 %), 6.9 % (95 % CI = 5.3 %,8. %), and 2.6 % (95 % CI = 1.6 %,3.6 %), respectively. HIV prevalence changed from 8.2 % (95 % CI = 0.5 %,15.9 %) in 2010 to 1.7 % (95 % CI = 0.4 %,3.0 %) in 2014, and the prevalence decreased notably among FSW who were younger than 25 years old, stayed less than six months, and who participated in the HIV prevention services (P < 0.05). The syphilis prevalence also ranged from 8.2 % (95 % CI = 0.5 %,15.9 %) in 2010 to 3.9 % (95 % CI = 1.9 %,5.9 %) in 2014, and the prevalence remained relatively stable among FSW who reported inconsistent condom use with clients in the past month, those who did not participate in HIV prevention services, and had lower HIV knowledge (P > 0.05). HCV prevalence increased from 0 % in 2010 to 2.2 % (95 % CI = 0.7 %, 3.7 %) in 2014. Multivariable analyses revealed that infection with HCV increased the odds of HIV and syphilis infection. Drug use (aOR = 44.0, 95C % = 16.3,129.5) increased the odds of HCV infection. The relatively higher HIV, syphilis and HCV prevalence among Vietnamese FSW compared to their Chinese counterparts sets a challenge for health officials at both sides. To curb the epidemic among the cross-border FSW, preventive action requires bilateral cooperation and action by health authorities of China and Vietnam. A national-level response system should be launched in order to tackle the urgently ever-increasing epidemic.
