Prevalence of obesity, hypertension and diabetes among people living with HIV in South Africa: a systematic review and meta-analysis. BMC Infect Dis 2023; 23:861. [PMID: 38062372 PMCID: PMC10704741 DOI: 10.1186/s12879-023-08736-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 10/23/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND HIV has become a manageable chronic condition due to the success and scale-up of antiretroviral therapy (ART). Globally, South Africa has the highest number of people living with HIV (PLHIV) and research evidence indicates that countries with the highest burden of PLHIV have a substantial burden of obesity, hypertension (HPT) and type 2 diabetes (T2D). We sought to summarize the burden of these three common NCDs among PLHIV in South Africa. METHODS In this systematic review, multiple databases were searched for articles reporting on the prevalence of obesity, HPT, and T2D among PLHIV in South Africa published since journal inception until March 2022. A meta-analysis was conducted using random-effects models to obtain pooled prevalence estimates of the three NCDs. Heterogeneity was assessed using X2 test on Cochran's Q statistic. RESULTS We included 32 studies, with 19, 22 and 18 studies reporting the prevalence of obesity, HPT, and T2D among PLHIV, respectively. The overall prevalence of obesity, HPT, and T2D was 23.2% [95% CI 17.6; 29.9], 25.5% [95% CI 15.6; 38.7], and 6.1% [95% CI 3.8; 9.7] respectively. The prevalence of obesity was significantly higher among women (P = 0.034) compared to men, however the prevalence of HPT and T2D did not differ by sex. The prevalence of each of the three NCDs did not differ significantly between rural, urban, and peri-urban areas. The prevalence of obesity and T2D was higher in studies conducted between 2013 and 2022 compared to studies conducted between 2000 and 2012, while the prevalence of HPT was higher between 2000 and 2012 compared to between 2013 and 2022. CONCLUSIONS These findings suggest that South Africa is experiencing a syndemic of NCDs among people PLHIV highlighting the need to increase cost-effective interventions and management strategies that involve integrated HIV and NCD care in the South African setting.

J Acquir Immune Defic Syndr 2022; 91:101-108. [PMID: 35972856 DOI: 10.1097/qai.0000000000003025] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Accepted: 05/16/2022] [Indexed: 11/25/2022]
Abstract
BACKGROUND Obesity is increasing worldwide including in people living with HIV (PLWH). Antiretroviral pharmacokinetic data in obesity are limited. OBJECTIVES To measure antiretroviral drug concentrations in obese and nonobese PLWH treated with the fixed-dose combination of efavirenz-tenofovir-emtricitabine. To determine pharmacokinetic differences across indicators of obesity and their associated immunovirological outcomes. METHODS We conducted a cross-sectional sample analysis of 2 cohort studies. We measured mid-dose efavirenz, 8-hydroxy-efavirenz, tenofovir, and emtricitabine concentrations. Antiretroviral drug concentrations were analyzed by body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR). RESULTS We performed a study of 213 participants: General obesity was detected in 20.4% using BMI and abdominal obesity in 53.6% using WC and 62.4% using WHR, respectively. The median concentrations of all antiretroviral drugs were lower among obese participants determined by BMI and WC, with efavirenz showing greater differences than tenofovir or emtricitabine. For BMI, results were most striking for efavirenz (1752.3 vs 2342.9 ng/mL, P = 0.002) with lower concentrations in obese participants. Using WC, efavirenz (1845.8 vs 2571.2 ng/mL, P < 0.001), tenofovir (65.8 vs 73.2 ng/mL, P = 0.036), and emtricitabine (159.5 vs 221.0 ng/mL, P = 0.005) concentrations were lower in obese participants. Eight-hydroxyefavirenz concentrations were similar in nonobese and obese participants for WC. Using WHR, the concentrations of all antiretroviral drugs were lower in the obese population, most strikingly for emtricitabine (173.5 vs 229.0 ng/mL, P = 0.015). There were no immunovirological associations. CONCLUSION We found lower antiretroviral concentrations in all obese groups, most strikingly in participants with abdominal obesity determined by WC. Lower drug concentrations had no immunovirological associations.

Disparities in breast cancer survival between women with and without HIV across sub-Saharan Africa (ABC-DO): a prospective, cohort study. Lancet HIV 2022; 9:e160-e171. [PMID: 35245508 PMCID: PMC9031563 DOI: 10.1016/s2352-3018(21)00326-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 11/13/2021] [Accepted: 12/07/2021] [Indexed: 12/30/2022]
Abstract
BACKGROUND Studies have shown increased mortality among women living with HIV diagnosed with breast cancer compared with HIV-negative women with breast cancer. We aimed to examine how this HIV differential varies by patient or breast tumour characteristics. METHODS The African Breast Cancer-Disparities in Outcomes (ABC-DO) study is a prospective cohort of women (aged ≥18 years) with incident breast cancer recruited consecutively at diagnosis (2014-17) from hospitals in Namibia, Nigeria, South Africa, Uganda, and Zambia. Detailed clinical and epidemiological data, including self-reported or tested HIV status, were collected at baseline. Participants were actively followed up via telephone calls every 3 months. The primary outcome was all-cause mortality, assessed in all women who had at least one updated vital status after baseline interview. Using Cox regression, we examined differences in overall survival by HIV status in the cohort, and across country and patient subgroups, adjusted for age, tumour grade, and tumour stage at cancer diagnosis. FINDINGS Between Sept 8, 2014, and Dec 31, 2017, we recruited 2154 women with primary breast cancer, 519 of whom were excluded due to their countries having small numbers of women with HIV for comparison. Among the remaining 1635 women, 313 (19%) were living with HIV, 1184 (72%) were HIV negative, and 138 (9%) had unknown HIV status. At breast cancer diagnosis, women with HIV were younger and had lower body-mass index (BMI) than their HIV-negative counterparts, but had similar tumour stage, grade, and receptor subtypes. At the end of the follow-up (Jan 1, 2019), a higher proportion of women with HIV (137 [44%] of 313) had died than had HIV-negative women (432 [37%] of 1184). Crude 3-year survival was 9% lower for women with HIV (46% [95% CI 40-53]) than for HIV-negative women (55% [52-59]; hazard ratio (HR) 1·41 [1·15-1·74]). The HIV survival differential did not differ by age, BMI, tumour subtype, or tumour grade, but was stronger in women with non-metastatic disease (3-year survival 52% HIV-positive vs 63% HIV-negative women, adjusted HR 1·65 [1·30-2·10]), whereas women with metastatic cancer had low survival, regardless of HIV status. INTERPRETATION The larger survival deficit among women with HIV with non-metastatic breast cancer calls for a better understanding of the reasons underlying this differential (eg, biological mechanisms, health behaviours, detrimental HIV-breast cancer treatment interactions, or higher HIV background mortality) to inform strategies for reducing mortality among this patient group.

Association between food intake and obesity in pregnant women living with and without HIV in Cape Town, South Africa: a prospective cohort study. BMC Public Health 2021; 21:1504. [PMID: 34348683 PMCID: PMC8335890 DOI: 10.1186/s12889-021-11566-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2020] [Accepted: 05/24/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Although global nutrition/dietary transition resulting from industrialisation and urbanisation has been identified as a major contributor to widespread trends of obesity, there is limited data in pregnant women, including those living with HIV in South Africa. We examined food-based dietary intake in pregnant women with and without HIV at first antenatal care (ANC) visit, and associations with maternal overweight/obesity and gestational weight gain (GWG). METHODS In an urban South African community, consecutive women living with (n = 479) and without (n = 510) HIV were enrolled and prospectively followed to delivery. Interviewer-administered non-quantitative food frequency questionnaire was used to assess dietary intake (starch, protein, dairy, fruits, vegetables, legumes, oils/fats) at enrolment. Associations with maternal body mass index (BMI) and GWG were examined using logistic regression models. RESULTS Among women (median age 29 years, IQR 25-34), the prevalence of obesity (BMI ≥ 30 kg/m2) at first ANC was 43% and that of excessive GWG (per IOM guidelines) was 37% overall; HIV prevalence was 48%. In women without HIV, consumption of potato (any preparation) (aOR 1.98, 95% CI 1.02-3.84) and pumpkin/butternut (aOR 2.13, 95% CI 1.29-3.49) for 1-3 days a week increased the odds of overweight/obesity compared to not consuming any; milk in tea/coffee (aOR 6.04, 95% CI 1.37-26.50) increased the odds of excessive GWG. Consumption of eggs (any) (aOR 0.52, 95% CI 0.32-0.86) for 1-3 days a week reduced the odds of overweight/obesity while peanut and nuts consumption for 4-7 days a week reduced the odds (aOR 0.34, 95% CI 0.14-0.80) of excessive GWG. In women with HIV, consumption of milk/yoghurt/maas to drink/on cereals (aOR 0.35, 95% CI 0.18-0.68), tomato (raw/cooked) (aOR 0.50, 95% CI 0.30-0.84), green beans (aOR 0.41, 95% CI 0.20-0.86), mixed vegetables (aOR 0.49, 95% CI 0.29-0.84) and legumes e.g. baked beans, lentils (aOR 0.50, 95% CI 0.28-0.86) for 4-7 days a week reduced the odds of overweight/obesity; tomato (raw/cooked) (aOR 0.48, 95% CI 0.24-0.96) and mixed vegetables (aOR 0.38, 95% CI 0.18-0.78) also reduced the odds of excessive GWG. CONCLUSIONS Diet modification may promote healthy weight in pregnant women living with and without HIV.

Abstract
BACKGROUND Obesity is common among people living with HIV (PLWH) and early-stage infection, yet associations with combination antiretroviral (cART) adherence are unclear. METHODS Among PLWH initiating cART in Uganda and South Africa, body mass index (BMI) was assessed at cART initiation, and cART adherence was monitored in real-time over 12 months. The association of obesity (BMI ≥ 30 kg/m2) with adherence was assessed among nonpregnant participants with CD4 > 350 cells/mm3 using fractional regression modeling. RESULTS Among 322 participants, median age was 32 years, 70% were female, and 54% were from Uganda. Prevalence of obesity was 12% in Uganda and 28% in South Africa. Mean overall cART adherence was 83% in Uganda and 66% in South Africa. Participants with obesity had higher adherence than those without obesity: +3.6% (p = 0.44) in Uganda and +11.4% (p = 0.02) in South Africa. CONCLUSION Obesity at cART initiation was common and associated with higher adherence, although only significantly in South Africa.

Abstract
PURPOSE OF REVIEW The present review aims to decipher common co-morbidities faced by people living with HIV in low- to middle-income countries, and in particular the sub-Saharan region, which hosts the majority of the HIV burden worldwide. RECENT FINDINGS Well-controlled chronic HIV disease is strongly associated with an increased risk of developing cardiovascular disease. This is partly due to the natural aging process, however recent studies show that using antiretroviral therapy as well as the HIV disease itself may be predisposing factors to the development of cardiovascular diseases, creating a new burden for healthcare facilities in the region. Furthermore, newly completed studies assessing inflammation marker albuminuria and age-related syndrome frailty have been found in a higher prevalence than in non-HIV people, with increased morbidity and mortality. SUMMARY As antiretroviral medication continues to be well supplied in the region and well tolerated by patients living with HIV, this group is now reckoning with cardiovascular ailments faced by all ageing population therefore there is a need for cardiovascular care systems to be better integrated within the existing, well-performing HIV care cascade to address this burden.

Abstract
BACKGROUND The deleterious effects of hypoalbuminaemia in the peri-operative period are well documented. We aimed to review serum albumin levels in a cohort of orthopaedic trauma patients to determine the prevalence of hypoalbuminaemia. Secondarily, we aimed to identify factors associated with an increased risk of hypoalbuminaemia. METHODS A retrospective cross-sectional study was performed of data collected prospectively at a regional hospital serving primarily a rural population in South Africa. RESULTS Two hundred ninety-five patients were included in the study. Twenty-nine per cent of the cohort was found to have hypoalbuminaemia. Femur neck fractures (p < 0.001), intertrochanteric fractures (p = 0.004), tibial plateau fractures (p = 0.034) and polytrauma (p = 0.013) were associated with hypoalbuminaemia. The mean albumin level was lower in HIV-positive patients when compared to HIV-negative patients (35.7 g/L vs 37.5 g/L, p = 0.007). The presence of comorbidities other than HIV, like diabetes mellitus (p = 0.001), previous pulmonary tuberculosis (p = 0.034) and chronic renal failure (p = 0.007) was associated with hypoalbuminaemia. CONCLUSION In this cohort of orthopaedic trauma patients from rural South Africa, we found a 29% prevalence of hypoalbuminaemia at the time of presentation. High-risk subgroups include patients with pre-existing comorbidities and increased age, as well as patients presenting with polytrauma, femoral neck, intertrochanteric femur or tibial plateau fractures.

Abstract
Background Levels of obesity are rising in South Africa, notably among adolescent females. Excessive energy-dense diets and physical inactivity are among the factors contributing to this increase. Given that these factors are largely behavioural, understanding young people’s views of obesity can contribute to more targeted behavioural interventions. Yet little is known of how rural South African adolescents view obesity. Objectives The aim of this study was to explore rural South African adolescents’ views of obesity, including their understanding of its causes, consequences, and solutions. Methods This qualitative study took place within the MRC/Wits Rural Public Health and Health Transitions Research Unit (Agincourt) study area, in rural northeast South Africa. Three focus group discussions were held with male (n = 16) and female adolescents (n = 15), aged 14–19 years in 2018. Data were analysed using thematic analysis and the Social Cognitive Theory used to frame the findings. Results Participants presented conflicting views of obesity, with both positive and negative opinions expressed. Causes of obesity were seen to be multifactorial, including genetics, diet, lack of physical activity, and HIV treatment. Adolescents proposed medication and hospitalisation as ways to address obesity. When discussing interventions to address obesity, adolescents expressed the need for more information, suggesting that providing information to both themselves and their family members as part of interventions would be important. Conclusions Rural South African adolescents have a complex perspective of obesity, likely driven in part by the current nutrition transition underway and do not inherently see individual behaviour as a driver or mitigator of obesity. Complex interventions including the involvement of other household members are needed to change adolescents’ views on the role of the individual, and ultimately, change both individual and household behaviour to prevent obesity.

The Nutritional Status of Adult Antiretroviral Therapy Recipients with a Recent HIV Diagnosis; A Cross-Sectional Study in Primary Health Facilities in Gauteng, South Africa. Healthcare (Basel) 2020; 8:healthcare8030290. [PMID: 32846888 PMCID: PMC7551417 DOI: 10.3390/healthcare8030290] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Revised: 08/10/2020] [Accepted: 08/15/2020] [Indexed: 01/08/2023] Open
Abstract
The study determined the nutritional status of adult antiretroviral therapy (ART) recipients, and investigated the association between the duration on ART and the nutritional status. This study was based in primary health facilities in Gauteng, South Africa. The data collected included sociodemographic variables; the duration of the treatment; and the body mass index (BMI), classified as undernutrition (<18.5 kg/m2), normal (18.5–24.9 kg/m2), or overweight/obesity (≥25 kg/m2). ART recipients (n = 480) had a mean age of 35 (± 8.4SD) years. All had taken ART for six months or more (range 6–48 months). The data were analyzed using STATA 13.0. The overall prevalence of overweight/obesity was 39%, it was higher in females (46%) than in males (30%), 26% were overweight, and 13% were obese. Underweight was 13%, and was higher in males (18%) than females (9%). Being overweight was more likely in those aged ≥35 years and those in smaller households. Being obese was less likely in males, in the employed, and in those with a higher income, but was more likely in those with a longer duration on ART. Abdominal obesity was high, but less likely in males. Interventions to prevent overweight/obesity should be integrated into routine HIV care, while at the same time addressing the burden of undernutrition among ART recipients.

Magnitude of Obesity/Overweight and Its Associated Factors Among HIV/AIDS Patients on Antiretroviral Therapy in Jimma Zone Hospitals, South West Ethiopia: Hospital-Based Cross-Sectional Study. Diabetes Metab Syndr Obes 2020; 13:1251-1258. [PMID: 32368118 PMCID: PMC7183745 DOI: 10.2147/dmso.s247221] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Accepted: 04/04/2020] [Indexed: 12/21/2022] Open
Abstract
PURPOSE Obesity is on the rise worldwide, not only in the general population but also in PLWHA. Being overweight and obese are themselves risk factors for cardiovascular and other diseases. Despite this, few studies have been conducted to determine the magnitude of obesity/overweight and its associated factors among HIV/AIDS patients in Ethiopia, which necessitates this study. METHODS Hospital-based cross-sectional study was conducted from December to January 2019 at selected Jimma zone hospitals. WHO STEP-wise approach to chronic disease risk factor surveillance (STEPS) questionnaire and document review for HIV-related clinical factors was applied. Weight, height and waist circumference and hip circumference were measured. Data were analyzed using SPSS version 20. RESULTS A total of 252 participants with a response rate of 95.8% were included. The prevalence of obesity/overweight was 21%. After adjusting for these variables, age category of greater than 50 years [AOR = 0.4, 95% CI (0.2, 0.9), p = 0.03], WHO clinical stage III and above [AOR = 0.04, 95% CI (0.002, 0.6), p = 0.02], presence of mild to moderate physical activity [AOR = 1.3, 95% CI (5.5, 33.3), p ≤ 0.001)], plasma CD4 count between 351 and 500 copies/mL [AOR=0.15, 95% CI (0.04, 0.6) p=0.024], and female sex [AOR = 2.6, 95% CI (1.25, 10) p=0.03)] were significantly associated with obesity/overweight. CONCLUSION There was a high prevalence of obesity/overweight among HIV/AIDS patients. It was found that older age, female sex, early stage of the disease, lower CD4 count and presence of mild to moderate physical activity were significant predictors of obesity/overweight. Clinicians should be aware of the health consequence of obesity and consider instituting targeted weight management programs as a part of routine HIV care.
