Do challenges still exist amongst HIV/AIDS patients in managing their condition? A cross-sectional study of 297 participants in the Ethekwini Metro of KwaZulu-Natal, South Africa

Food Insecurity Is Associated With Low Tenofovir Diphosphate in Dried Blood Spots in South African Persons With HIV

Background

Food insecurity has been linked to suboptimal antiretroviral therapy (ART) adherence in persons with HIV (PWH). This association has not been evaluated using tenofovir diphosphate (TFV-DP) in dried blood spots (DBSs), a biomarker of cumulative ART adherence and exposure.

Methods

Within a prospective South African cohort of treatment-naive PWH initiating ART, a subset of participants with measured TFV-DP in DBS values was assessed for food insecurity status. Bivariate and multivariate median-based regression analysis compared the association between food insecurity and TFV-DP concentrations in DBSs adjusting for age, sex, ethnicity, medication possession ratio (MPR), and estimated glomerular filtration rate.

Results

Drug concentrations were available for 285 study participants. Overall, 62 (22%) PWH reported worrying about food insecurity and 44 (15%) reported not having enough food to eat in the last month. The crude median concentrations of TFV-DP in DBSs differed significantly between those who expressed food insecurity worry versus those who did not (599 [interquartile range {IQR}, 417-783] fmol/punch vs 716 [IQR, 453-957] fmol/punch; P = .032). In adjusted median-based regression, those with food insecurity worry had concentrations of TFV-DP that were 155 (95% confidence interval, -275 to -35; P = .012) fmol/punch lower than those who did not report food insecurity worry. Age and MPR remained significantly associated with TFV-DP.

Conclusions

In this study, food insecurity worry is associated with lower TFV-DP concentrations in South African PWH. This highlights the role of food insecurity as a social determinant of HIV outcomes including ART failure and resistance.

Age and Mental Health Symptoms Among Chinese Persons With HIV: The Mediating and Moderating Role of Perceived Discrimination

ABSTRACT

The association between age and mental health symptoms among persons with HIV (PWH) is inconsistent, and little is known about the mediators and moderators of this association. This study aimed to examine the association between age and mental health symptoms, as well as the mediators and moderators of perceived discrimination. Data were from 1,304 PWH who completed a cross-sectional survey in five areas of China. Multiple linear regressions showed that younger age was significantly associated with more severe mental health symptoms and that perceived discrimination moderated this relationship. The Sobel test showed that perceived discrimination also mediated the association between age and mental health symptoms. Our study indicates that perceived discrimination shapes the association between age and mental health symptoms among PWH and highlights the importance of designing age-tailored mental health intervention strategies for perceived discrimination among young PWH. Interventions addressing discrimination are necessary to help improve mental health, especially for young PWH.

Hepatitis A virus seroprevalence among children and adolescents in a high-burden HIV setting in urban South Africa

Hepatitis A virus (HAV) infection is one of the most important global causes of viral hepatitis. Recent reviews suggested that HAV endemicity in South Africa could shift from high to intermediate. A hospital-based HAV seroprevalence study was conducted between February 2018 and December 2019 in Pretoria, South Africa. Systematic sampling was performed on children and adolescents (1-15 years) who attended outpatient services. Participants with a known HIV status and valid HAV serology results were included. Of the 1220 participants, the median age was 7 years (IQR: 4-11), with 648 (53.11%) males and 572 (46.89%) females. Of 628 (51.48%) HIV-infected participants, most (329, 71.83%) were both immunologically and virologically controlled or had low-level viremia (74, 16.16%). Almost three-quarters (894, 73.28%) were living in formal dwellings, and just over half (688, 56.39%) had access to clean water sources inside the house. Increasing age was associated with testing HAV IgG-positive (OR 1.25; 95% CI 1.20-1.30, p < 0.001), with 19.8% of participants one year of age compared with 86.7% of participants 15 years of age. This study suggests that South Africa has an intermediate HAV seroprevalence, with rates < 90% by 10 years of age (68.6%). Increased age and informal dwellings are statistically associated with HAV seropositivity, while HIV status does not significantly influence HAV seropositivity.

Functioning Problems Associated with Health Conditions with Greatest Disease Burden in South Africa: A Scoping Review

A notable rise in health-related disability for which evidence-based rehabilitation is beneficial is evident in low-to-middle income countries. This scoping review aimed to systematically identify and map the most common functioning problems associated with health conditions that contribute most to disability in South Africa using the International Classification of Functioning, Disability and Health (ICF) framework. Peer-reviewed evidence published from January 2006 to December 2021 was systematically searched from five databases. Some 268 studies reporting on functioning problems (impairments, activity limitations, and participation restrictions) in South African adults (>18 years) related to 10 health conditions were included. A total of 130 different functioning problems were mapped to the ICF. The most prevalent problems (top 20) were related to mobility, pain, and mental health but spanned across several ICF domains and were mostly in patients at primary care. The high prevalence and wide range of functioning problems may be particularly burdensome on an already strained primary health care (PHC) system. This points towards targeted planning of innovative strategies towards strengthening rehabilitation service delivery at primary care to address these complexities where there is an inadequate rehabilitation workforce.

Factors associated with ART adherence among HIV-positive adherence club members in Ekurhuleni Metropolitan Municipality, South Africa: A cross-sectional study

BACKGROUND

HIV is a leading cause of morbidity and mortality in South Africa that can be managed using antiretroviral therapy (ART). Adherence clubs are interventions that have been introduced to decentralize ART to improve ART adherence and provide social support for club members. However, ART adherence can be suboptimal even among adherence club members.

AIM

This study aimed to determine the factors affecting ART adherence among people living with HIV/AIDS (PLWHA) attending adherence clubs in Ekurhuleni Metropolitan Municipality.

METHODS

A cross-sectional study was conducted. Ordinal logistic regression was used in univariable and multivariable analyses to determine factors significantly associated with adherence scores. Factors included in the final model were age, comorbidity, ART regimen and club membership duration.

RESULTS

The records of 730 participants were analysed. After adjusting for age, participants with comorbidities were half as likely to report high ART adherence scores compared to participants without comorbidities (AOR = 0.5, 95% CI: 0.3-0.8, p = 0.005). The adjusted odds of reporting high levels of adherence among participants on cART were 1.8 times those on a single tablet regimen (AOR = 1.8, 95% CI: 1.0-3.2; p = 0.033). There was a 20% reduction in the adjusted odds of reporting high ART adherence for each additional year of adherence club membership (AOR = 0.8, 95% CI: 0.8-0.9, p<0.001).

CONCLUSION

Increasing years spent as adherence club members, single tablet ART regimens and the presence of comorbidities were all significantly associated with low ART adherence among study participants. Regular assessment of the quality of counselling sessions for ART adherence club members and questionnaires for early screening of treatment fatigue have been suggested as tools for improved adherence in ART adherence club settings.

A Qualitative Study: Hypertension Stigma Among Black Women

BACKGROUND

The prevalence of hypertension (HTN) in Blacks is among the highest in the world. For Black women, 46% experience stage 2 HTN (blood pressure [BP] ≥140/90 mm Hg) as compared with 42% of Black men. Because of higher rates of stage 2 HTN, Black women have greater rates of cardiovascular disease and stroke. For reasons unknown, nonadherence to lifestyle modifications and antihypertensive medications continues. An understudied potential factor associated with poor adherence to the treatment regimen and negative health outcomes is stigma.

OBJECTIVE

The aim of this study was to gain insight and describe the psychological factor of stigma as an influence on poorly controlled HTN in Black women.

METHODS

Hypertensive Black women attending a 6-week self-management program were invited to participate in an open-ended questionnaire. Six groups were held with 62 women aged 24 to 70 years, with group size ranging from 10 to 15. Women anonymously wrote their answer to 2 questions to capture individual responses without group persuasion. Data were analyzed using thematic analysis.

RESULTS

Five themes were generated inductively from the data and included (1) desire to get control, (2) shame and embarrassment, (3) obesity characterizations, (4) stereotype threats, and lastly, (5) disrupted normality. During member checking, younger participants were more vocal about stigma, whereas older participants did not view stigma as problematic.

CONCLUSIONS

Hypertension stigma could potentially deter adherence to high BP treatment. Further research is needed to explore the prevalence of stigma in this population and its impact on behaviors that hinder BP control.
