The effect of gender on food insecurity among HIV-infected people receiving anti-retroviral therapy: A systematic review and meta-analysis

Food Insecurity Prevalence and Risk Factors among Persons with HIV in a Southeastern US Clinical Care Setting

Food insecurity (FI) is associated with adverse health outcomes for persons with HIV (PWH). Little is known about FI among PWH in southern or non-urban settings. We examined FI prevalence, risk factors, and access to services in a southeastern HIV clinic. Among PWH in the UNC CFAR HIV Clinical Cohort who were screened for FI as part of HIV care between 2021 and 2022, we estimated unadjusted prevalence ratios (PRs) comparing the probability of reporting FI by demographic and clinical characteristics. The 479 PWH screened for FI were 65% cisgender men, 62% non-Hispanic Black PWH, a median of 54 years old (IQR 41-62), and 93% with an HIV viral load (VL) < 200 copies/mL. FI prevalence was 36.3% (95% CI 32.3%-40.9%). Cisgender women and transgender adults were more likely to report FI than cisgender men (PRs 1.24 [95% CI 0.97-1.59] and 2.03 [1.32-3.12], respectively). Compared with White PWH, the PR was 1.71 (1.20-2.42) for Black and 2.44 (1.56-3.82) for Hispanic PWH. The PR was 1.42 (0.98-2.05) for PWH with VL ≥ 200 versus < 200 copies/mL. Having no or public versus private health insurance was also associated with FI. PWH with FI had a high prevalence of comorbidities including hypercholesterolemia (49%) and hypertension (48%), though these were not associated with FI. Almost half of PWH with FI were not accessing a food pantry or nutrition assistance program. Identifying FI in PWH is critical as FI is common and may contribute to viral non-suppression, poor comorbidity control, and gender and racial/ethnic health disparities in PWH.

Person-centred care for older adults living with HIV in sub-Saharan Africa

More than a fifth of people living with HIV in the US President's Emergency Plan for AIDS Relief-supported programmes are older individuals, defined as aged 50 years and older, yet optimal person-centred models of care for older adults with HIV in sub-Saharan Africa, including screening and treatment for geriatric syndromes and common comorbidities associated with ageing, remain undefined. This Position Paper explores the disproportionate burden of comorbidities and geriatric syndromes faced by older adults with HIV, with a special focus on women. We seek to motivate global interest in improving quality of life for older people with HIV by presenting available research and identifying research gaps for common geriatric syndromes, including frailty and cognitive decline, and multimorbidity among older people with HIV in sub-Saharan Africa. We share two successful models of holistic care for older people with HIV that are ongoing in Zimbabwe and Kenya. Lastly, we provide policy, research, and implementation considerations to best serve this growing population.

Dietary diversity and nutritional status of adults living with HIV during the COVID-19 era

BACKGROUND

The coronavirus Disease 2019 (COVID-19) pandemic has brought about unique challenges in healthcare and nutrition, particularly for people living with HIV (PLHIV). Understanding their dietary patterns and nutritional status is crucial for developing targeted interventions and improving health outcomes. Therefore, this study assessed the dietary diversity and nutritional status of PLHIV during the COVID-19 era.

METHODS

We adopted a facility-based cross-sectional study design to enroll 220 PLHIV from two hospitals in the Central Region of Ghana. Dietary intakes were assessed using 24-hour recall. Anthropometric and body composition data were collected with a stadiometer and a body composition monitor. Dietary diversity was evaluated using the FAO's Individual Dietary Diversity Score (IDDS). Data analysis was conducted with SPSS version 20. Significance level was set p-value less than 0.05.

RESULTS

A significant proportion (33.2%) of PLHIV had low dietary diversity, with the majority (55.5%) categorized as needing dietary improvement. Approximately 2 out of every 10 of the participants were identified as underweight. Participants aged 40 to 59 years were more likely to exhibit higher dietary diversity (adjusted odds ratio (AOR) = 1.966, 95% Confidence Interval (CI): 1.045-4.987). Participants who consumed meals at least three times daily were more likely to have a high IDDS (AOR = 1.641, 95% CI: 1.221, 8.879). Employed participants (public sector and private sector) were also more likely to have a high IDDS compared to unemployed participants (AOR = 1.448, 95% CI: 1.028-3.042; AOR = 1.165, 95% CI: 1.030-9.329, respectively). Factors associated with undernutrition included being female (AOR = 1.829, 95% CI: 1.294, 3.872) and first-line antiretroviral therapy ART (AOR = 1.683, 95% CI: 1.282-2.424).

CONCLUSION

The study emphasizes the need for nutritional interventions for PLHIV, particularly during crises. It advocates for a policy collaboration to address food insecurity and promote resilient health outcomes.

Association of Body Mass Index with Risk of Household Catastrophic Health Expenditure in China: A Population-Based Cohort Study

Catastrophic health expenditure (CHE) is a major obstacle to achieving universal health coverage, and body mass index (BMI) is linked to both health and economy. We aimed to explore the association of BMI with the risk of CHE to provide advice for reducing CHE. We used national cohort data from the China Family Panel Studies, which comprised 33,598 individuals (14,607 households) from 25 provinces between 2010 to 2018. We used multivariate Cox proportional hazard models to estimate adjusted hazard ratios (aHRs) and 95% confident interval (CI) for CHE in participants at underweight, overweight, and obesity, compared with those at normal weight. Restricted cubic splines were employed to model the association of continuous BMI scale with risk of CHE. We found that families with female household heads at underweight had a 42% higher risk of CHE (aHR = 1.42, 95%CI: 1.16-1.75), and those at overweight had a 26% increased risk of CHE (aHR = 1.26, 95%CI: 1.09-1.47), compared with those at normal weight. A weak U-shaped curve for the association of continuous BMI with risk of CHE in female-headed households (p for non-linear = 0.0008) was observed, which was not significant in male-headed households (p for non-linear = 0.8725). In female-headed households, underweight and overweight BMI are connected with a higher risk of CHE. Concerted efforts should be made to keep a normal BMI to prevent CHE.

The role of material deprivations in determining ART adherence: Evidence from a conjoint analysis among HIV-positive adults in Uganda

Despite sustained global scale-up of antiretroviral therapy (ART), adherence to ART remains low. Less than half of those in HIV care in Uganda achieve 85% adherence to their ART medication required for clinically meaningful viral suppression, leaving them at higher risk of transmission. Key barriers to ART adherence include poverty-related structural barriers that are inter-connected and occur simultaneously, making it challenging to examine and disentangle them empirically and in turn design effective interventions. Many people living with HIV (PLWH) make tradeoffs between these various barriers (e.g., between expenses for food or transportation) and these can influence long-term health behavior such as adherence to ART. To be able to estimate the distinct influence of key structural barriers related to poverty, we administered a conjoint analysis (CA) to 320 HIV-positive adults currently taking ART at an urban clinic in Uganda between July 2019 and September 2020. We varied the levels of four poverty-related attributes (food security, sleep deprivation, monthly income, and physical pain) that occur simultaneously and asked respondents how they would adhere to their medication under different combinations of attribute levels. This allows us to disentangle the effect of each attribute from one another and to assess their relative importance. We used regression analysis to estimate the effects of each attribute level and found that food security impacts expected adherence the most (treatment effect = 1.3; 95% CI 1.11-1.49, p<0.001), followed by income (treatment effect = 0.99; 95% CI 0.88-1.10, p<0.001. Sleep and pain also impact adherence, although by a smaller magnitude. Sub-group analyses conducted via regression analysis examine heterogeneity in results and suggest that the effects of material deprivations on expected adherence are greater among those with high levels of existing food insecurity. Results from this CA indicate that external factors inherent in the lives of the poor and unrelated to direct ART access can be important barriers to ART adherence. This study applies a CA (typically administered in marketing applications) among PLWH to better understand individual-level perceptions relating to poverty that often occur simultaneously. Policy interventions should address food insecurity and income to improve adherence among HIV-positive adults.

Interpersonal violence and other social-structural barriers associated with needing HIV treatment support for women living with HIV

Women living with HIV (WLWH), experience disproportionate rates of violence, along with suboptimal HIV health outcomes, despite recent advancements in HIV treatment, known as antiretroviral therapy (ART). The objectives of this study were to: (a) describe different types of support needed to take ART and (b) investigate the social and structural correlates associated with needing support for ART adherence among WLWH. Data are drawn from Sexual health and HIV/AIDS: Women's Longitudinal Needs Assessment, a community-based open research cohort with cisgender and transgender WLWH, aged 14+ who live or access HIV services in Metro Vancouver, Canada (2014-present). Baseline and semi-annual questionnaires are administered by community interviewers alongside a clinical visit with a sexual health research nurse. Bivariate and multivariable logistic regression using generalized estimating equations and an exchangeable working correlation matrix was used to model factors associated with needing supports for ART adherence. Among 276 WLWH, 51% (n = 142) reported needing support for ART adherence; 95% of participants reported lifetime gender-based violence and identified many interpersonal, structural, community, and clinical supports that would facilitate and support ART adherence. In multivariable logistic regression, participants who were Indigenous (adjusted odds ratio [AOR]: 1.70, 95% confidence intervals [CI]: 1.07-2.72), or otherwise racialized (AOR: 2.36, 95% CI : 1.09-5.12) versus white, experienced recent gender-based physical violence (AOR : 1.54, 95% CI : 1.03-2.31), lifetime post-traumatic stress disorder (AOR : 1.97, 95% CI : 1.22-3.18), and recent illicit drug use (AOR : 2.15, 95% CI : 1.43-3.22), had increased odds of needing support for ART adherence. This research suggests a need for trauma-informed, culturally safe and culturally responsive practice and services for WLWH along the HIV care continuum to support ART adherence. All services should be developed by, with, and for WLWH and tailored according to gender identity, taking into account history, culture, and trauma, including the negative impacts of settler colonialism for Indigenous people.

Prevalence and predictors of food insecurity among people living with and without HIV in the African Cohort Study

OBJECTIVE

We determined the prevalence and identified predictors of food insecurity in four African countries.

DESIGN

Cross-sectional analyses at study enrolment.

SETTING

From January 2013 to March 2020, people living with HIV (PLWH) and without HIV were enrolled at twelve clinics in Kenya, Uganda, Tanzania and Nigeria.

PARTICIPANTS

Participants reporting not having enough food to eat over the past 12 months or receiving <3 meals/d were defined as food insecure. Robust Poisson regression models were used to estimate unadjusted and adjusted prevalence ratios (aPR) and 95 % CI for predictors of food insecurity among all participants and separately among PLWH.

RESULTS

1694/3496 participants (48·5 %) reported food insecurity at enrolment, with no difference by HIV status. Food insecurity was more common among older participants (50+ v. 18-24 years aPR 1·35, 95 % CI 1·15, 1·59). Having 2-5 (aPR 1·14, 95 % CI 1·01, 1·30) or >5 dependents (aPR 1·17, 95 % CI 1·02, 1·35), and residing in Kisumu West, Kenya (aPR 1·63, 95 % CI 1·42, 1·87) or Nigeria (aPR 1·20, 95 % CI 1·01, 1·41) was associated with food insecurity. Residing in Tanzania (aPR 0·65, 95 % CI 0·53, 0·80) and increasing education (secondary/above education v. none/some primary education aPR 0·73, 95 % CI 0·66, 0·81) was protective against food insecurity. Antiretroviral therapy (ART)-experienced PLWH were more likely to be food secure irrespective of viral load.

CONCLUSION

Food insecurity was highly prevalent in our cohort though not significantly associated with HIV. Policies aimed at promoting education, elderly care, ART access in PLWH and financial independence could potentially improve food security in Africa.

Weight change after antiretroviral therapy initiation among adults living with HIV in Northwest Ethiopia: a longitudinal data analysis

OBJECTIVES

The first objective was to explore weight change in the first 2 years after antiretroviral therapy (ART) initiation in adults living with HIV. The second objective was to identify the predictors of weight change over time among adults living with HIV on ART.

DESIGN

An institution-based retrospective longitudinal study was conducted.

SETTING

The study was conducted at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia.

PARTICIPANTS

The study included 848 randomly selected medical charts of adults living with HIV receiving ART between June 2014 and June 2020.

PRIMARY AND SECONDARY OUTCOMES

The primary outcome was weight change in the first 2 years after ART initiation. The secondary outcome was to identify predictors of weight change. Association between predictor variables and weight change was assessed using an LMM. Variables with p values <0.05 in the final model were considered as statistically significant predictors of weight change.

RESULTS

Of 844 study participants, more than half (n=499; 58.8%) were female. Participants' mean weight increased from 54.2 kg (SD ±9.6 kg) at baseline to 59.5 kg (SD ±10.7 kg) at the end of follow-up. Duration of time on ART, sex, WHO clinical disease staging, functional status, nutritional status and presence of opportunistic infections were significant predictors of weight change at ART initiation. Significant interaction effects were observed between time and sex, WHO clinical disease staging, functional status, isoniazid preventive therapy and nutritional status.

CONCLUSION

We found a linear increment of weight over 24 months of follow-up. Rate of weight gain over time was lower in patients with advanced disease stage and working functional status, whereas weight gain rate was higher in male and underweight patients.

HIV Infections and Food Insecurity Among Pregnant Women from Low- and Middle-Income Countries: A Systematic Review and Meta-analysis

There are few studies on the occurrence of food insecurity (FI) in pregnant women living with HIV/AIDS (PrWLWHA). Our objective was to estimate the prevalence of food insecurity among PrWLWHA and to analyse the association between HIV and FI. For this we searched eight databases. We used the prevalence and prevalence ratio (PR) with a 95% confidence interval (CI) as the summary measurements for the meta-analysis. We identified 300 studies, 13 of which were eligible. The prevalence of FI was 64%, ranging between 26% (mild), 33% (moderate) and 27% (severe). People living with HIV/AIDS (PLWHA) had a 23% greater chance of facing FI (PR = 1.23, 95% CI 1.16-1.38) compared to those not living with HIV. The results revealed a high prevalence and positive association with FI among PLWHA, which suggests the need for food security assessments in HIV/AIDS clinical care.

Evidence for factors associated with diet and physical activity in African and Caribbean countries

Objective

To identify and describe summarized evidence on factors associated with diet and physical activity in low- and middle-income countries in Africa and the Caribbean by performing a scoping review of reviews.

Methods

We searched the Medline®, LILACS, Scopus, Global Health and Web of Science databases for reviews of factors associated with diet or physical activity published between 1998 and 2019. At least 25% of studies in reviews had to come from African or Caribbean countries. Factors were categorized using Dahlgren and Whitehead's social model of health. There was no quality appraisal.

Findings

We identified 25 reviews: 13 on diet, four on physical activity and eight on both. Eighteen articles were quantitative systematic reviews. In 12 reviews, 25-50% of studies were from Africa or the Caribbean. Only three included evidence from the Caribbean. Together, the 25 reviews included primary evidence published between 1926 and 2018. Little of the summarized evidence concerned associations between international health or political factors and diet or associations between any factor and physical activity across all categories of the social model of health.

Conclusion

The scoping review found a wide range of factors reported to be associated with diet and physical activity in Africa and the Caribbean, but summarized evidence that could help inform policies encouraging behaviours linked to healthy diets and physical activity in these regions were lacking. Further reviews are needed to inform policy where the evidence exists, and to establish whether additional primary research is needed.

Food Insecurity and T-cell Dysregulation in Women Living With Human Immunodeficiency Virus on Antiretroviral Therapy

BACKGROUND

Food insecurity is associated with increased morbidity and mortality in people with human immunodeficiency virus (HIV) on antiretroviral therapy, but its relationship with immune dysregulation, a hallmark of HIV infection and comorbidity, is unknown.

METHODS

In 241 women participating in the Women's Interagency HIV Study, peripheral blood mononuclear cells were characterized by flow cytometry to identify cell subsets, comprising surface markers of activation (%CD38+HLADR+), senescence (%CD57+CD28-), exhaustion (%PD-1+), and co-stimulation (%CD57- CD28+) on CD4+ and CD8+ T cells. Mixed-effects linear regression models were used to assess the relationships of food insecurity with immune outcomes, accounting for repeated measures at ≤3 study visits and adjusting for sociodemographic and clinical factors.

RESULTS

At the baseline study visit, 71% of participants identified as non-Hispanic Black, 75% were virally suppressed, and 43% experienced food insecurity. Food insecurity was associated with increased activation of CD4+ and CD8+ T cells, increased senescence of CD8+ T cells, and decreased co-stimulation of CD4+ and CD8+ T cells (all P < .05), adjusting for age, race/ethnicity, income, education, substance use, smoking, HIV viral load, and CD4 count. In stratified analyses, the association of food insecurity with CD4+ T-cell activation was more pronounced in women with uncontrolled HIV (viral load >40 copies/mL and CD4 <500 cells/mm3) but remained statistically significant in those with controlled HIV.

CONCLUSIONS

Food insecurity may contribute to the persistent immune activation and senescence in women with HIV on antiretroviral therapy, independently of HIV control. Reducing food insecurity may be important for decreasing non-AIDS-related disease risk in this population.
