Longitudinal Analysis of the Relationship Between Internalized HIV Stigma, Perceived Social Support, Resilience, and Depressive Symptoms Among People Living with HIV in China: A Four-Wave Model.

Depression is one of the most common mental health problems among people living with HIV (PLWH). However, the longitudinal psychological mechanism underlying the link of internalized HIV stigma and depressive symptoms remains a research gap. This study attempted to articulate how and to what extent perceived social support and resilience mediate the longitudinal associations between internalized HIV stigma and depressive symptoms. A sample consisting of 1,098 Chinese PLWH (Mage = 38.63, SD = 9.20; 63.9% male) with a six-month interval and four waves of follow-up was used in the current study. Participants were asked to complete self-report questionnaires. The associations among main study variables were examined via a complete longitudinal mediation approach. Results indicated that the linkage between internalized HIV stigma at T1 and depressive symptoms at T4 was serially mediated by perceived social support at T2 and resilience at T3, and perceived social support at T2 and depressive symptoms at T3 serially mediated the relationship between resilience at T1 and internalized HIV stigma at T4. Depressive symptoms at a previous time point consistently predicted the levels of internalized HIV stigma at subsequent time points. The study highlights the complex interplay between internalized HIV stigma, mental health problems, and protective factors in a longitudinal context. The findings suggest the need to incorporate interventions aimed at enhancing social support and resilience in mental health programs for PLWH, as these factors may interrupt the pathway from internalized HIV stigma to depressive symptoms and potentially improve the overall psychological well-being of this population.

Lower rate of mpox vaccination hesitancy and medical consultation among Chinese men who have sex with men living with HIV in comparison with those living without HIV: A national observational study

ABSTRACT This anonymous cross-sectional study aimed to investigate the relationships between HIV infection and mpox-related focus issues among Chinese men who have sex with men (MSM). This study involved in 27 MSM social organizations and was conducted from July 31 to August 4, 2023. Mpox vaccination hesitancy was defined as the proportion of participants who expressed unwillingness to receive self-funded and free vaccines. Logistic regression models were employed to estimate odds ratios (OR) and 95% confidence interval (95%CI). Of 7196 MSMs, the prevalence of mpox differed between people living with HIV (PLWH) (1.04%, 20/1920) and people living without HIV (PLWoH) (0.55%, 29/5276) (P = .037). However, after adjusting for all covariates, there was no significant association between HIV status and mpox (aOR = 1.17; 95%CI = 0.58, 2.39; P = .658). Furthermore, the crude rates of vaccination hesitation (PLWoH: 5.91%, PLWH: 4.11%; P = .004) and consultation hesitation (PLWoH: 16.22%, PLWH: 10.78%; P < .001) were both lower in the PLWH. Compared with PLWoH, PLWH had lower odds ratios of vaccination hesitation (aOR = 0.70; 95%CI = 0.53, 0.92; P = .011) and consultation hesitation (aOR = 0.74; 95%CI = 0.60, 0.90; P = .003) among MSM. The estimate of association between HIV status and consultation hesitation was even smaller among MSM who reported hepatitis C infection or uncertainty (aOR = 0.30; 95%CI = 0.15, 0.56), compared with those without hepatitis C (aOR = 0.73; 95%CI = 0.60, 0.89) (P for interaction = .037). MSM living with HIV in China demonstrated a greater willingness to accept mpox vaccination and medical consultation. In the future, it is recommended that medical institutions establish good medical environment to control the mpox epidemic, especially for PLWH.

Psychological Mechanisms of Internalized HIV Stigma Affect Sleep Impairment among People Living with HIV in China: A follow-up Study.

Prior studies have demonstrated that HIV-related stigma (e.g., internalized HIV stigma) is detrimental to the physical and mental health (e.g., sleep impairment and depressive symptoms) of people living with HIV (PLWH). However, follow-up data are limited regarding the longitudinal relationships between internalized HIV stigma, future orientation, self-esteem, depressive symptoms, and sleep impairment. The present study attempted to examine a mediation model involving these variables among Chinese PLWH. A two-wave follow-up design (6 months intervals) was employed in a final sample of 1,140 Chinese PLWH (Mage = 41.63, SD = 9.29, age range: 21-67 years; 64.6% men). Participants completed Internalized HIV Stigma Scale, Optimism About the Future Scale, Rosenberg Self-Esteem Scale, Center of Epidemiological Studies Depression Scale, and an adapted version of Pittsburgh Sleep Quality Index. Results revealed that internalized HIV stigma at baseline had a significant direct relationship with sleep impairment over time, and a significant indirect relationship with increased sleep impairment over time via future orientation and depressive symptoms. Furthermore, the linkage between internalized HIV stigma and sleep impairment was serially mediated via self-esteem and depressive symptoms. This study highlights the deleterious effects of internalized HIV stigma on the physical and psychological health of PLWH. The findings suggest that interventions targeting internalized HIV stigma and related factors such as future orientation, self-esteem, and depressive symptoms may facilitate improvements in sleep quality and overall well-being among PLWH.

Perspectives of Local Communities on the Impact of Chinese Aid: A Case Study of China's Aid Projects in the Education Sector in Guinea

China's re-emergence as an aid donor has attracted the attention and criticism from Western donors, academia, and the media. In contrast to traditional donors, China's aid has been portrayed as anti-poverty aid, mainly due to its combination with other instruments, such as investment, and the absence of any political or economic conditions. This paper examines the impact of Chinese aid projects in Guinea's education sector from the perspective of the beneficiaries. The author collected data from both primary (interviews) and secondary (document analysis) sources. The present study concludes that China's aid projects in the education sector have received both positive and negative feedback, mainly because the recipients' needs have not been appropriately targeted. This study contributes to the literature on China's role in Africa. More specifically, it discusses the conditions for aid effectiveness in the field of education. Moreover, in the context of the globalization of aid practices, the study proposes best practices for China to adopt in order to improve the practices of its aid delivery. The novelty of this study lies in the methodology (qualitative method) used to understand China's aid from the perspective of the beneficiaries of its aid.

A Comparison of the EU and China's Aid Policies in Africa

Since the beginning of the 21st century, the rise of African power has become a major factor influencing the international political situation, but Africa itself is still objectively lagging most parts of the world in terms of its level of development. China and the European Union, in conjunction with the UN's development programme, have become important players in supporting Africa's rise. As a long-established political and economic phenomenon in state relations, foreign aid policy is also an extension of the internal political economy of national alliances or organizations of states and is one of the most important means by which each state can safeguard its economic interests and achieve its strategic objectives. China and the EU differ in their aid policies towards Africa and have many features that can be learned from each other. By starting from the aid policies of China and the EU towards Africa and using comparative regionalism as a theoretical guide, this paper summarizes the strengths and weaknesses of the aid policies of the two parties towards Africa and will propose constructive ideas for the establishment of a new inter-aid international structure and the promotion of closer cooperation between China, the EU and Africa.

Incidence, clearance, and factors associated with anal human papilloma virus infection among men with HIV.

This study aims to estimate the incidence and persistence/clearance of anal human papilloma virus (HPV) infection and related factors among men with HIV in Taizhou, China. A prospective cohort study. Men with HIV were recruited and followed up from 2016 to 2021. Questionnaire surveys were used to collect social-demographic and behavioral characteristics, and anal swabs were collected for HPV Genotyping. A total of 675 men with HIV were recruited and followed up. After an average follow-up time of 1.75 years, HPV39 (3.8/100 person-years), HPV52 (3.6/100 person-years), HPV51 (3.1/100 person-years), HPV58 (2.5/100 person-years) and HPV16 (2.4 cases/100 person-years) in the high-risk types showed the highest incidence rate. In marriage with woman [adjusted hazard ratio (aHR) = 0.44, 95% confidence interval (CI) 0.20-0.99] showed an inverse association with HPV incidence, while bisexuality or undetermined sexual orientation (aHR = 2.62, 95% CI 1.08-6.36) showed a positive association. For those infected at baseline, the top three high-risk HPV with the lowest clearance density were HPV52 (32.2/100 person-years), HPV58 (38.1/100 person-years), and HPV16 (43.5/100 person-years). Daily consumption of 1-28 g alcohol (aHR = 0.62, 95% CI 0.41-0.95) showed an inverse association with HPV clearance, while illicit drug use (aHR = 3.24, 95% CI 1.59-6.59) showed a positive association. Anal HPV infection and clearance were both active in men with HIV in China. Marriage status and sexuality were associated with the incidence of HPV infection, while substance use including alcohol and illicit drug were associated with HPV clearance. More studies are needed to explore the risk factors of HPV persistence.

Enhancing Mental Health and Medication Adherence Among Men Who Have Sex With Men Recently Diagnosed With HIV With a Dialectical Behavior Therapy-Informed Intervention Incorporating mHealth, Online Skills Training, and Phone Coaching: Development Study Using Human-Centered Design Approach.

Mental health problems are common among men who have sex with men (MSM) living with HIV and may negatively affect medication adherence. Psychosocial interventions designed to address these urgent needs are scarce in China. Incorporating behavioral health theories into intervention development strengthens the effectiveness of these interventions. The absence of a robust theoretical basis for interventions may also present challenges to identify active intervention ingredients. This study aims to systematically describe the development of a mobile health-based intervention for MSM recently diagnosed with HIV in China, including the theoretical basis for the content and the considerations for its technological delivery. We used intervention mapping (IM) to guide overall intervention development, a behavioral intervention technology model for technological delivery design, and a human-centered design and cultural adaptation model for intervention tailoring throughout all steps of IM. The dialectical behavior therapy (DBT)-informed intervention, Turning to Sunshine, comprised 3 components: app-based individual skills learning, group-based skills training, and on-demand phone coaching. The theoretical basis for the intervention content is based on the DBT model of emotions, which fits our conceptualization of the intervention user's mental health needs. The intervention aims to help MSM recently diagnosed with HIV (1) survive moments of high emotional intensity and strong action urges, (2) change emotional expression to regulate emotions, and (3) reduce emotional vulnerability, as well as (4) augment community resources for mental health services. Technological delivery considerations included rationale of the medium, complexity, and esthetics of information delivery; data logs; data visualization; notifications; and passive data collection. This study laid out the steps for the development of a DBT-informed mobile health intervention that integrated app-based individual learning, group-based skills training, and phone coaching. This intervention, Turning to Sunshine, aims to improve mental health outcomes for MSM newly diagnosed with HIV in China. The IM framework informed by human-centered design principles and cultural adaptation considerations offered a systematic approach to develop the current intervention and tailor it to the target intervention users. The behavioral intervention technology model facilitated the translation of behavioral intervention strategies into technological delivery components. The systematic development and reporting of the current intervention can serve as a guide for similar intervention studies. The content of the current intervention could be adapted for a broader population with similar emotional struggles to improve their mental health outcomes.

Psychosocial Factors Predicting HIV Disclosure Stage Transitions: An Evaluation of A Theory-Based Parental HIV Disclosure Intervention among Parents Living with HIV in China.

Appropriate parental HIV disclosures (i.e., parents living with HIV [PLH] tell their HIV diagnosis to their children) benefit parents, children, and family relations. Psychosocial factors could influence the decision-making process of parental HIV disclosure. Using the Health Action Process Approach to frame stages (pre-intention, intention, and action) in the decision-making process, this study aimed to investigate how psychosocial factors predict HIV disclosure stage transitions among PLH in China. Data were collected from a randomized clinical trial of a theory-based parental HIV disclosure intervention among 791 PLH. The predictive effects of psychosocial factors on disclosure stage transitions were examined using a Markov chain model matrix. Results showed that action self-efficacy and action planning were significant predictors of parental HIV disclosure stage transitions. Considering stage-specific psychosocial predictors may contribute to effective interventions to promote appropriate HIV disclosure among PLH in China.

Chinese aid and corruption in African local governments

AbstractDoes foreign aid reshape citizen views on governments? How does Chinese aid relate to corruption perception in African local governments? Studying 33 African countries from 2000 to 2014 (175 590 respondents), Chinese aid heightens perceived corruption in local councillors and officials. Corruption scandals likely contribute to negative views of both China and local governance. Control variables like World Bank aid and Confucius Institutes disprove alternate theories. Heterogeneous effects demonstrate that China's aid is unwelcome among low‐skilled individuals who feel threatened by its expansion, magnifying corruption perception. This suggests that Chinese aid's unfavourable image fosters scepticism among African citizens and undermines collaborating local governments.

Immediate and long-term outcomes after treat-all among people living with HIV in China: an interrupted time series analysis

BackgroundIn 2003, China implemented free antiretroviral therapy (ART) for people living with HIV (PLHIV), establishing an eligibility threshold of CD4 < 200 cells/μl. Subsequently, the entry criteria were revised in 2012 (eligibility threshold: CD4 ≤ 350 cells/μl), 2014 (CD4 ≤ 500 cells/μl), and 2016 (treat-all). However, the impact of treat-all policy on HIV care and treatment indicators in China is unknown. We aimed to elucidate the immediate and long-term impact of the implementation of treat-all policy in China.MethodsAnonymized programmatic data on ART initiation and collection in PLHIV who newly started ART were retrieved between 1 January 2015 and 31 December 2019, from two provincial and municipal Centers for Disease Control and Prevention and ten major infectious disease hospitals specialized in HIV care in China. We used Poisson and quasi-Poisson segmented regression models to estimate the immediate and long-term impact of treat-all on three key indicators: monthly proportion of 30-day ART initiation, mean CD4 counts (cells/μl) at ART initiation, and mean estimated time from infection to diagnosis (year). We built separate models according to gender, age, route of transmission and region.ResultsMonthly data on ART initiation and collection were available for 75,516 individuals [gender: 83.8% males; age: median 39 years, interquartile range (IQR): 28–53; region: 18.5% Northern China, 10.9% Northeastern China, 17.5% Southern China, 49.2% Southwestern China]. In the first month of treat-all, compared with the contemporaneous counterfactual, there was a significant increase in proportion of 30-day ART initiation [+ 12.6%, incidence rate ratio (IRR) = 1.126, 95% CI: 1.033–1.229; P = 0.007] and mean estimated time from infection to diagnosis (+ 7.0%, IRR = 1.070, 95% CI: 1.021–1.120; P = 0.004), while there was no significant change in mean CD4 at ART initiation (IRR = 0.990, 95% CI: 0.956–1.026; P = 0.585). By December 2019, the three outcomes were not significantly different from expected levels. In the stratified analysis, compared with the contemporaneous counterfactual, mean CD4 at ART initiation showed significant increases in Northern China (+ 3.3%, IRR = 1.033, 95% CI: 1.001–1.065; P = 0.041) and Northeastern China (+ 8.0%, IRR = 1.080, 95% CI: 1.003–1.164; P = 0.042) in the first month of treat-all; mean estimated time from infection to diagnosis showed significant increases in male (+ 5.6%, IRR = 1.056, 95% CI: 1.010–1.104; P = 0.016), female (+ 14.8%, IRR = 1.148, 95% CI: 1.062–1.240; P < 0.001), aged 26–35 (+ 5.3%, IRR = 1.053, 95% CI: 1.001–1.109; P = 0.048) and > 50 (+ 7.8%, IRR = 1.078, 95% CI: 1.000–1.161; P = 0.046), heterosexual transmission (+ 12.4%, IRR = 1.124, 95% CI: 1.042–1.213; P = 0.002) and Southwestern China (+ 12.9%, IRR = 1.129, 95% CI: 1.055–1.208; P < 0.001) in the first month of treat-all.ConclusionsThe implementation of treat-all policy in China was associated with a positive effect on HIV care and treatment outcomes. To advance the work of rapid ART, efforts should be made to streamline the testing and ART initiation process, provide comprehensive support services, and address the issue of uneven distribution of medical resources.

Perceived social support and depression among people living with HIV in China: roles of stigma and adherence self-efficacy

IntroductionPeople living with HIV (PLHIV) are a high-risk group for depression. In particular, the prevalence and burden of depression is higher and more severe among PLHIV in developing and less-developed countries. There is evidence that perceived social support has a positive impact on reducing the occurrence of depression, and high stigma and low adherence self-efficacy are barriers to the effectiveness of social support for depressed PLHIV. However, how these risks affect the effect of social support on depression still needs further identification.MethodsBetween 2017 and 2018, a total of 1139 Chinese PLHIV (74.36% male, mean age = 43.91 years) from three provinces (Shanghai, Zhejiang and Henan) in China were enrolled in the study. Data were analyzed by multiple regression, mediation model, and moderation model.ResultsA total of 43.99% of PLHIV had mild to severe depression. There was a significant negative association between perceived social support and depression (B = -0.049, P < 0.05). Stigma and adherence self-efficacy played a chain mediating role (B = -0.058, 95% CI: -0.078 ~ 0.039) and a moderating role in the effect of perceived social support on depression (stigma: B = -0.003, P < 0.05; adherence self-efficacy: B = 0.004, P < 0.05).ConclusionStigma and adherence self-efficacy indirectly predicted depression, and perceived social support was more effective in reducing depression among PLHIV with high stigma or low adherence self-efficacy. Enhancing multiple social support resources for PLHIV may reduce their risk of depression. Moreover, the need for social support is greater for those with high stigma or low adherence self-efficacy.

Correlates of Sexual Lifestyles Among Older Adults Living With HIV in China: Findings From the Sexual Well-being (SWELL) Study

Abstract Sexual lifestyles are closely related to overall human health and well-being. Few studies have focused on sexual lifestyles among older adults living with HIV (OALHIV), especially in low- and middle-income countries. This study is a part of the sexual well-being among older adults in China (SWELL) study, which is a multi-centre cross-sectional study focused on sexual health among older adults aged 50 years and older. Participants were 680 OALHIV (≥ 50 years old) from the SWELL study conducted from June 2020 to December 2022. Data were collected through one-on-one interviews. We used logistic regression to assess the correlates of sexual activity and sexual satisfaction. Among all participants, 37.1% were sexually active. Being older, male, in a steady relationship, and employed were associated with being sexually active. The prevalence of sexual satisfaction was 69.8% among sexually active OALHIV. Being homosexual and reporting a better general health status were associated with sexual satisfaction. OALHIV who have depressive symptoms were less likely to report sexual satisfaction. To support holistic healthy ageing among OALHIV, it is important for healthcare providers to be educated about the importance of enquiring about sexual activity, satisfaction and problems, and addressing concerns whilst conveying sex-positive attitudes during clinical reviews, as these are still critical aspects of their health and well-being.

Associations Between Internalized and Anticipated HIV Stigma and Depression Symptoms Among People Living with HIV in China: A four-wave Longitudinal Model.

Previous research has documented that HIV-related stigma (e.g., internalized and anticipated stigma) is detrimental to the mental health of people living with HIV (PLWH). However, longitudinal data on the bidirectional relationship between HIV-related stigma and depression symptoms are limited. The purpose of this study was to examine the bidirectional association among internalized and anticipated HIV stigma and depression symptoms among Chinese PLWH. A four-wave longitudinal design (6 months intervals) was employed among 1,111 Chinese PLWH (Mage = 38.58, SD = 9.16, age range: 18-60 years; 64.1% men). The bidirectional model was examined using a random-intercept cross-lagged panel model (RI-CLPM), which evaluated the within- and between-person effects of study variables. At the within-person level, results indicated that depression symptoms at T2 mediated the linkage between internalized HIV stigma at T1 and anticipated HIV stigma at T3, and that anticipated HIV stigma at both T2 and T3 mediated the relationship between depression symptoms at the previous time point and internalized HIV stigma at the subsequent time point. Furthermore, a bidirectional association was found between anticipated HIV stigma and depression symptoms across four waves. At the between-person level, internalized and anticipated HIV stigma were significantly associated with depression symptoms. This study highlights the complex interplay between different forms of HIV-related stigma and mental health problems among PLWH and underscores the importance of considering the bidirectional relationship between the development of psychopathology and stigmatization process in clinical practice.

Preoperative Biomarkers and Survival in Chinese Breast Cancer Patients with HIV: A Propensity-Score-Matched-Cohort Study.

China initiated its national free antiretroviral therapy program in 2004 and saw a dramatic decline in mortality among the population with HIV. However, the morbidity of non-AIDS-defining cancers such as breast cancer is steadily growing as life expectancy improves. The aim of this study was to investigate the clinical characteristics and prognosis of breast cancer patients with HIV in China. Data from 21 breast cancer patients with HIV and 396 breast cancer patients without HIV treated at the Shanghai public health clinical center from 2014-2022 was collected. After propensity score matching, 21 paired patients in the two groups were obtained and compared. The optimal cut-off value of preoperative biomarkers for recurrence was determined via maximally selected log-rank statistics. Preoperative biomarkers were categorized into high and low groups, based on the best cut-off values and compared using Kaplan-Meier survival curves and the log-rank test. The Cox proportional hazards regression model was used to perform univariate and multivariate analyses. The median follow-up time was 38 months (IQR: 20-68 months) for the propensity-score-matching cohort. The progression-free survival at 1, 2 and 3 years for patients with and without HIV were 74.51%, 67.74%, and 37.63% and 95.24%, 95.24%, and 90.48%, respectively. The overall survival for patients with HIV at 1, 2 and 3 years were 94.44%, 76.74%, and 42.63%. After multivariate analysis, Only HIV status (hazard ratios (HRs) = 6.83, 95% [confidence intervals (CI)] 1.22-38.12) were associated with progression-free survival. Based on the best cut-off value, CD8 showed discriminative value for overall survival (p = 0.04), whereas four variables, the lymphocyte-to-monocyte ratio (p = 0.02), platelet-to-lymphocyte ratio (p = 0.03), CD3 (p = 0.01) and CD8 (p < 0.01) were suggested be significant for progression-free survival. The univariate analysis suggested that CD3 (HRs = 0.10, 95% [CI] 0.01-0.90) and lymphocyte-to-monocyte ratio (HRs = 0.22, 95% [CI] 0.05-0.93) were identified as significant predictors for progression-free survival. In this study, breast cancer in patients with HIV in China reflected a more aggressive nature with a more advanced diagnostic stage and worse prognosis. Moreover, preoperative immune and inflammatory biomarkers might play a role in the prognosis of breast cancer patients with HIV.

Sexual Risk Behavior and Satisfaction Among Men Who Have Sex With Men Living With Detectable HIV Viral Loads: A Nationwide Online Survey in China

Abstract Little is known about sexual behavior and satisfaction among men who have sex with men (MSM) with detectable HIV viral loads (VL) in China. This study aims to investigate sexual risk behavior and sexual satisfaction among MSM living with HIV in China, as well as potential predictors. This cross-sectional study was conducted in February 2021 using an anonymous online survey based on WeChat. Data were collected on sociodemographics, sexual behavior, HIV clinical information, sexual satisfaction and mental health. Descriptive statistics, logistic regression and multivariable logistic regression were performed. MSM with detectable HIV VL (VL+) or VL not sure were more likely to report inconsistent condom use, even with HIV-negative/unknown-status regular male partners. Having an HIV-positive regular partner and recreational drug use were positively associated with inconsistent condom use during anal sex among MSM with undetectable VL (VL−). Alcohol use before or during sexual activities was positively associated with inconsistent condom use during anal sex among VL+ or VL not sure MSM. A total of 58.3% of participants reported being sexually satisfied. MSM living with HIV who were currently employed, had experienced anal sex in the prior 6 months, had VL− HIV status, or had more frequent ejaculation during sex/masturbation were more likely to report sexual satisfaction. The development of targeted education and interventions to minimize sexual risk behavior among MSM living with HIV is in dire need. Treating sexual dysfunction and developing a reasonable antiretroviral therapy regimen to achieve viral suppression can help promote sexual satisfaction in MSM living with HIV.

Fear of COVID and Physical Health Among People Living with HIV in China: Mediation Effects of HIV Stigma, Social Support, and Substance Use

The COVID-19 pandemic has uniquely impacted people living with HIV (PLWH) worldwide. The negative impacts on PLWH’s mental health from fear of COVID-19 are labeled as “a double stress.” The association between fear of COVID-19 and HIV (internalized) stigma has been found among PLWH. Studies that explore the relationships between fear of COVID-19 and physical health outcomes are few, especially among PLWH. In this study, we explored the relationship between fear of COVID-19 and physical health among PLWH and the mediated effects of HIV stigma, social support, and substance use. A cross-sectional online survey of PLWH (n = 201) from November 2021 to May 2022 was carried out in Shanghai, China. The data on socio-demographics, fear of COVID-19, physical health, HIV-related perceived stigma, social support, and substance use were gathered and analyzed by structure equation modeling (SEM). In SEM analysis, fear of COVID-19 showed a significant and indirect effect on physical health (β=-0.085) which was primarily mediated by HIV stigma. In SEM analysis, the final model had a good fit. Fear of COVID-19 showed a significant effect on HIV stigma (β = 0.223) with the majority being direct effects (β = 0.262) and a small indirect effect via substance use (β=-0.039). Furthermore, HIV stigma showed a significant effect on physical health (β=-0.382), the majority of which was direct (β=-0.340), and a small indirect effect via social support (β=-0.042). This is one of the first studies to explore how fear of contracting COVID-19 can affect PLWH’s coping behaviors (e.g., using substances and obtaining social support) used to combat HIV stigma as well as to achieve better physical health in China.

Safety and Immunogenicity of the Inactivated COVID-19 Vaccine Booster in People Living with HIV in China.

Current knowledge regarding the long-term humoral response of people infected with human immunodeficiency virus to the third dose of inactivated coronavirus disease (COVID-19) vaccine is incomplete. As a result, concerns remain about the safety and efficacy of the vaccination. To improve our understanding of the safety and immunogenicity of the COVID-19 inactivated vaccine booster in people living with HIV (PLWH), a prospective study was conducted on participants who had not yet received a third dose of the COVID-19 inactivated vaccine, had no history of SARS-CoV-2 infection, and had received a second dose of the vaccine more than six months prior. The primary safety outcomes included the incidence of adverse reactions, changes in CD4+ T-cell count, viral load, blood routine examination, liver and kidney function examination, blood sugar, and blood lipid examination. The pseudovirus-neutralizing antibody responses to the D614G variant, Delta variant, and Omicron variants BA.5 and BF.7 were evaluated before vaccination, 14 days, 28 days, 3 months, and 6 months after vaccination to evaluate the immune response of PLWH to the injection of inactivated vaccine booster and the safety of the vaccine. In conclusion, COVID-19 vaccine booster shots were effective in PLWH, resulting in an increase in the number of CD4+ T-cells, neutralizing antibodies that lasted up to six months, and higher levels of neutralizing antibodies lasting approximately 3 months. However, the vaccine protection against the two variants of BA.5 and BF.7 was significantly lower than that of D614G and Delta.

Chinese Mothers' Intent to Disclose Their HIV Status to Their Children: The Role of Positive Outcome Expectations and Reward Responsiveness.

Objective: The current study investigated the role of positive outcome expectations and reward responsiveness in intention to disclose HIV status to children among women living with HIV in China. The moderating role of reward responsiveness was also explored. Method: A 1-year longitudinal survey was conducted. 269 women living with HIV who had at least one child aged >5years and had not yet disclosed their HIV status to their oldest child were selected from a larger sample of women living with HIV at baseline, with a total of 261 respondents completing the follow-up survey. Results: After adjusting for significant socio-demographic and medical variables, positive outcome expectations positively predicted mothers' intention to disclose HIV, while reward responsiveness had a negative effect. A moderation effect of reward responsiveness was found, with further analysis showing that reward responsiveness has strengthened the relationship between positive outcome expectations and intention to disclose HIV. Conclusion: Findings support the relevance of positive outcome expectations and reward responsiveness to intention of disclosure among women living with HIV in China.

Associated Factors and Immune Response to the Hepatitis B Vaccine with a Standard Schedule: A Prospective Study of People with HIV in China.

Hepatitis B (HB) vaccination is recommended for people with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). We aimed to assess the immune response to the HB vaccine and associated factors using the standard vaccination schedule among people with HIV (PWH) in China. A prospective study was carried out from 2016 to 2020 in Beijing, China. PWH were given three 20 μg doses of recombinant HB vaccine at 0, 1, and 6 months. Blood samples were taken within 4-6 weeks after each dose to evaluate the anti-HBs levels. A total of 312 participants completed vaccination and serologic testing. The seroconversion (anti-HBs ≥ 10 IU/L) rates following the first, second, and third doses of the vaccine were 35.6% (95% CI: 30.3-40.9%), 55.1% (95% CI: 49.6-60.7%), and 86.5% (95% CI: 82.8-90.3%), respectively, and the geometric means of the anti-HBs titers were 0.8 IU/L (95% CI: 0.5-1.6 IU/L), 15.7 IU/L (95% CI: 9.4-26.3 IU/L), and 241.0 IU/L (95% CI: 170.3-341.1 IU/L), respectively. In multivariate analysis, after three doses of vaccination, age, CD4 cell count, and HIV-RNA viral load were significantly associated with strong, moderate, and weak response, respectively. These findings confirm that these personal health conditions are related to the HB response. HB vaccination in PWH using the standard schedule was still highly effective in the context of early treatment initiation, especially among participants aged 30 years and younger.

Does China's aid boost firm performance in recipient countries?

The effectiveness of China's aid has been highly debated. Our study uses firm-level data from the WBES and Global Chinese Official Finance Dataset to explore the impact of China's aid on firm performance using an instrumental variable analysis. The results show that China's aid has a positive impact on enterprise performance. We complemented our empirical tests by investigating the potential channels. China's aid may promote firm performance through the alleviation of infrastructure constraints. And it also relaxes financing constraints for firms. This study contributes to the literature by confirming the effectiveness of China's aid and highlights its implications for policymaking.
