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

Oral pathologies and underweight conditions among people living with HIV/AIDS in a health facility in Yaoundé, Cameroon: a study of 205 cases

BACKGROUND

Human immunodeficiency virus (HIV) infection is a public health concern worldwide. The clinical manifestations include underweight and oral lesions. The objective of this study was to assess the relationship between oral pathologies and underweight among HIV-positive patients in Yaoundé, Cameroon.

METHODS

We conducted a cross-sectional study between February 1st and 30th June 2021 at Yaoundé Central Hospital in Cameroon. A total of 205 HIV positive patients aged at least 18 years were recruited via consecutive sampling. The questionnaire consisted of sociodemographic information, anthropometric data, dietary habits, HIV history and treatment and oral examination data. The data were analysed with R software. Multivariate analysis was used to assess the risk of being underweight among HIV-positive patients with oral pathologies. A p value < 0.05 was considered to indicate statistical significance.

RESULTS

The prevalence of oral pathologies was 52.7% (95% CI: 45.6-59.6), and the main pathologies were candidiasis (40.5%, 95% CI: 33.7-47.5) and linear erythema (32.2%, 95% CI: 25.9-39.1). The prevalence of underweight was 20% (95% CI: 14.88-26.26). Binary logistic regression revealed that HIV-positive patients with oral pathologies were 10.89 (95% CI: 2.28-16.63) times more likely to be underweight than were HIV positive and AIDS patients without oral pathologies (p = 0.002).

CONCLUSION

Oral candidiasis and linear erythema were common in HIV positive and AIDS patients. HIV-positive and AIDS patients with these oral pathologies were at higher risk of being underweight than were those without oral pathologies. The effective medical care of these patients must include oral and nutritional management.

Prevalence of obesity, hypertension and diabetes among people living with HIV in South Africa: a systematic review and meta-analysis

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.

Body mass index trends and its impact of under and overweight on outcome among PLHIV on antiretroviral treatment in rural Tanzania: A prospective cohort study

INTRODUCTION

Increased body weight is an important risk factor for cardiovascular disease and is increasingly reported as a health problem in people living with HIV (PLHIV). There is limited data from rural sub-Saharan Africa, where malnutrition usually presents with both over- and undernutrition. We aimed to determine the prevalence and risk factors of underweight and overweight/obesity in PLHIV enrolled in a cohort in rural Tanzania before the introduction of integrase inhibitors.

METHODS

This nested study of the prospective Kilombero and Ulanga Antiretroviral Cohort included adults aged ≥19 years initiated on antiretroviral therapy between 01/2013 and 12/2018 with follow-up through 06/2019. Body Mass Index (BMI) was classified as underweight (<18.5 kg/m2), normal (18.5-24.9 kg/m2), or overweight/obese (≥25.0 kg/m2). Stratified piecewise linear mixed models were used to assess the association between baseline characteristics and follow-up BMI. Cox proportional hazard models were used to assess the association between time-updated BMI and death/loss to follow-up (LTFU).

RESULTS

Among 2,129 patients, 22,027 BMI measurements (median 9 measurements: interquartile range 5-15) were analysed. At baseline, 398 (19%) patients were underweight and 356 (17%) were overweight/obese. The majority of patients were female (n = 1249; 59%), and aged 35-44 years (779; 37%). During the first 9 months, for every three additional months on antiretroviral therapy, BMI increased by 2% (95% confidence interval 1-2%, p<0.0001) among patients underweight at baseline and by 0.7% (0.5-0.6%, p<0.0001) among participants with normal BMI. Over a median of 20 months of follow-up, 107 (5%) patients died and 592 (28%) were LTFU. Being underweight was associated with >2 times the hazard of death/LTFU compared to participants with normal BMI.

CONCLUSION

We found a double burden of malnutrition, with underweight being an independent predictor of mortality. Monitoring and measures to address both states of malnutrition among PLHIV should be integrated into routine HIV care.

Prevalence and characteristics of metabolic syndrome and its components among adults living with and without HIV in Nigeria: a single-center study

BACKGROUND

Persons living with HIV (PLHIV) now live longer due to effective combination antiretroviral therapy. However, emerging evidence indicates that they may be at increased risk for some cardiometabolic disorders. We compared the prevalence of metabolic syndrome (MetS) and its component disorders between persons living with and without HIV in Nigeria.

METHODS

This was a cross-sectional analysis of baseline data from a prospective cohort study of non-communicable diseases among PLHIV along with age- and sex-matched persons without HIV (PWoH) at the University of Abuja Teaching Hospital Nigeria. We collected sociodemographic and clinical data, including anthropometric measures and results of relevant laboratory tests. MetS was defined using a modification of the third report of the National Cholesterol Education Program Adult Treatment Panel (NCEP ATP III) criteria.

RESULTS

Of the 440 PLHIV and 232 PWoH, women constituted 50.5% and 51.3% respectively. The median age of the PLHIV was 45 years while that of the PWoH was 40 years. The prevalence of MetS was 30.7% (95% CI: 26.4%, 35.2%) and 22.8% (95% CI: 17.6%, 28.8%) among the PLHIV and PWoH respectively (P = 0.026). Independent associations were found for older age (P < 0.001), female sex (P < 0.001), family history of diabetes (P < 0.001), family history of hypertension (P = 0.013) and alcohol use (P = 0.015). The prevalence of component disorders for PLHIV versus PWoH were as follows: high blood pressure (22.3% vs 20.3%), prediabetes (33.8% vs 21.1%), diabetes (20.5% vs 8.2%), high triglycerides (24.5% vs 17.2%), low HDL-Cholesterol (51.1% vs 41.4%), and abdominal obesity (38.4% vs 37.1%). Adjusting for age and sex, prediabetes, diabetes, and low HDL-Cholesterol were significantly associated with HIV status. Duration on antiretroviral therapy, protease inhibitor-based regimen, CD4 count, and viral load were associated with some of the disorders mostly in unadjusted analyses.

CONCLUSION

We found a high burden of MetS and its component disorders, with significantly higher prevalence of dysglycemia and dyslipidemia among PLHIV as compared to PWoH. Integration of strategies for the prevention and management of MetS disorders is needed in HIV treatment settings.

Association Between Overweight/Obesity and ART Drug Regimen Among Adult HIV Patients in Gamo Zone Public Health Facilities Southern Ethiopia

Introduction

Overweight/obesity is an emerging public health problem in low income countries. Currently sub-Saharan African countries are facing a double burden of malnutrition. Evidence has shown that overweight/obesity is becoming a problem for people living with HIV. But little is known in our setting. Thus, this study is designed to assess the association between overweight/obesity and ART drug regimen among adult HIV patients in Gamo zone public health facilities southern Ethiopia.

Objective

To assess the association between overweight/obesity and ART drug regimen among adult HIV patients in Gamo zone public health facilities southern Ethiopia.

Methods

Institution-based cross-sectional study was conducted from April 10 to May 10, 2022, among systematically selected adult HIV patients. The data were collected by using a structured interviewer-administered questionnaire, patient record review, and physical measurements. Multivariate logistic regression model was used to assess the association between dependent and independent variables. A p-value <0.05 with its 95% CI was considered as a statistically significant and interpreted accordingly.

Results

The magnitude of overweight/obesity were 13.5% (95% CI:(10.4-17.2)). Being male (2.484(1.308, 4.716)), duration on ART (took for ≥5 years) ((2.249(1.218, 4.152)), and ART drug regime (3.789(1.965, 7.304)) were significantly associated with overweight/obesity.

Conclusion

Overweight/obesity is significantly associated to ART drug regimen type among adult HIV patients. Furthermore, sex and duration on ART drug were found significantly associated with overweight/obesity of adult HIV patients.

Self-Management of Diabetes and Associated Factors among Patients Seeking Chronic Care in Tshwane, South Africa: A Facility-Based Study

The burden of diabetes continues to increase in South Africa and a significant number of diabetes patients present at public primary healthcare facilities with uncontrolled glucose. We conducted a facility-based cross-sectional study to determine the diabetes self-management practices and associated factors among out-patients in Tshwane, South Africa. An adapted validated questionnaire was used to collect data on sociodemography, diabetes knowledge, and summaries of diabetes self-management activities measured in the previous seven days, and over the last eight weeks. Data were analysed using STATA 17. A final sample of 402 diabetes out-patients was obtained (mean age: 43 ± 12 years) and over half of them were living in poor households. The mean total diabetes self-management of score was 41.5 ± 8.2, with a range of 21 to 71. Almost two thirds of patients had average self-management of diabetes, and 55% had average diabetes knowledge. Twenty-two percent of patients had uncontrolled glucose, hypertension (24%) was the common comorbidity, and diabetic neuropathy (22%) was the most common complication. Sex [male: AOR = 0.55, 95% CI: 0.34-0.90], race [Coloured: AOR = 2.84, 95% CI: 1.69-4.77 and White: AOR = 3.84, 95% CI: 1.46-10.1], marital status [divorced: AOR = 3.41, 95% CI: 1.13-10.29], social support [average: AOR = 2.51, 95% CI: 1.05-6.00 and good: AOR = 4.49, 95% CI: 1.61-7.57], body mass index [obesity: AOR = 0.31, 95% CI: 0.10-0.95], diabetes knowledge [average: AOR = 0.58, 95% CI: 0.33-0.10 and good: AOR = 1.86, 95% CI: 0.71-4.91], and uncontrolled glucose [AOR = 2.97, 95% CI: 1.47-5.98] were factors independently predictive of diabetes self-management. This study emphasizes that the self-management of diabetes was mostly on average among patients and was associated with the aforementioned factors. Innovative approaches are perhaps needed to make diabetes education more effective. Face-to-face sessions delivered generally during clinic visits should be better tailored to the individual circumstances of diabetes patients. Considerations should be given to the options of leveraging information technology to ensure the continuity of diabetes education beyond clinic visits. Additional effort is also needed to meet the self-care needs of all patients.

Retrospective Analysis of the Outcome of Hospitalized COVID-19 Patients with Coexisting Metabolic Syndrome and HIV Using Multinomial Logistic Regression

Globally, the coexistence of metabolic syndrome (MetS) and HIV has become an important public health problem, putting coronavirus disease 19 (COVID-19) hospitalized patients at risk for severe manifestations and higher mortality. A retrospective cross-sectional analysis was conducted to identify factors and determine their relationships with hospitalization outcomes for COVID-19 patients using secondary data from the Department of Health in Limpopo Province, South Africa. The study included 15,151 patient clinical records of laboratory-confirmed COVID-19 cases. Data on MetS was extracted in the form of a cluster of metabolic factors. These included abdominal obesity, high blood pressure, and impaired fasting glucose captured on an information sheet. Spatial distribution of mortality among patients was observed; overall (21-33%), hypertension (32-43%), diabetes (34-47%), and HIV (31-45%). A multinomial logistic regression model was applied to identify factors and determine their relationships with hospitalization outcomes for COVID-19 patients. Mortality among COVID-19 patients was associated with being older (≥50+ years), male, and HIV positive. Having hypertension and diabetes reduced the duration from admission to death. Being transferred from a primary health facility (PHC) to a referral hospital among COVID-19 patients was associated with ventilation and less chance of being transferred to another health facility when having HIV plus MetS. Patients with MetS had a higher mortality rate within seven days of hospitalization, followed by those with obesity as an individual component. MetS and its components such as hypertension, diabetes, and obesity should be considered a composite predictor of COVID-19 fatal outcomes, mostly, increased risk of mortality. The study increases our understanding of the common contributing variables to severe manifestations and a greater mortality risk among COVID-19 hospitalized patients by investigating the influence of MetS, its components, and HIV coexistence. Prevention remains the mainstay for both communicable and non-communicable diseases. The findings underscore the need for improvement of critical care resources across South Africa.

A Systematic Review and Meta-Analysis on the Impact of Statin Treatment in HIV Patients on Antiretroviral Therapy

The rate of new human immunodeficiency virus (HIV) infections globally is alarming. Although antiretroviral therapy (ART) improves the quality of life among this group of patients, ARTs are associated with risk of cardiovascular diseases (CVD). Moreover, virally suppressed patients still experience immune activation associated with HIV migration from reservoir sites. Statins are widely recommended as therapeutic agents to control ART-related CVD; however, their impacts on the cluster of differentiation (CD)4 count and viral load are inconsistent. To assess the effect of statins on markers of HIV infections, immune activation and cholesterol, we thoroughly reviewed evidence from randomised controlled trials. We found 20 relevant trials from three databases with 1802 people living with HIV (PLHIV) on statin-placebo treatment. Our evidence showed no significant effect on CD4 T-cell count standardised mean difference (SMD): (-0.59, 95% confidence intervals (CI): (-1.38, 0.19), p = 0.14) following statin intervention in PLHIV on ART. We also found no significant difference in baseline CD4 T-cell count (SD: (-0.01, 95%CI: (-0.25, 0.23), p = 0.95). Our findings revealed no significant association between statins and risk of viral rebound in PLHIV with undetectable viral load risk ratio (RR): (1.01, 95% CI: (0.98, 1.04), p = 0.65). Additionally, we found a significant increase in CD8⁺CD38⁺HLA-DR⁺ T-cells (SMD (1.10, 95% CI: (0.93, 1.28), p < 0.00001) and CD4⁺CD38⁺HLA-DR⁺ T-cells (SMD (0.92, 95% CI: (0.32, 1.52), p = 0.003). Finally, compared to placebo, statins significantly reduced total cholesterol (SMD: (-2.87, 95% CI: (-4.08, -1.65), p < 0.0001)). Our results suggest that the statin lipid-lowering effect in PLHIV on ART may elevate immune activation without influencing the viral load and CD4 count. However, due to the limited evidence synthesised in this meta-analysis, we recommend that future powered trials with sufficient sample sizes evaluate statins' effect on CD4 count and viral load, especially in virally suppressed patients.

Development of Hypertension and Diabetes Mellitus, and Associated Factors, Among Adult HIV Patients in Ethiopia

Background

Medical improvements and increased access to treatment have turned HIV from a highly fatal disease into a treatable and controllable disease. With the improvement in lifespan, HIV patients face increasing morbidity and mortality from chronic comorbidities (hypertension and diabetes mellitus). There is, nevertheless, a paucity of information on the scale of HIV noncommunicable disease comorbidity and its associated factors. This study aimed to investigate the incidence and predictors of chronic comorbidity in HIV patients in a resource-limited setting.

Methods

A prospective cohort study was conducted from 2019 to 2021. We included 520 HIV patients at baseline. Patients without hypertension or diabetes were followed for two years to determine the incidence of developing comorbidities. Nine trained nurses used a pre-tested structured questionnaire to collect data during routine care consultations in three hospitals in southern Ethiopia. To find predictors of these chronic comorbidities, a multivariable logistic regression analysis was used.

Results

After two years, 54 out of 377 participants, or 14%, had chronic comorbidity, which is defined as having diabetes and/or hypertension. Hypertension (12%) and diabetes (4%), respectively, were observed. When compared to those who were not overweight, the risk of developing chronic comorbidity was three times higher in overweight people [AOR = 3.45, 95% CI: (1.04, 11.45), P = 0.045]. Older participants were about 6 times more likely than younger participants to have chronic comorbidity [AOR = 4.93, 95% CI: (1.56, 15.57), P = 0.007]. Those who did not engage in regular physical activity were twice as likely to develop chronic comorbidity [AOR = 2.16, 95% CI: (1.09, 4.29), P = 0.027].

Conclusion

The incidence of chronic comorbidity was high in the study population. Targeted screening for early signs of chronic comorbidity, nutritional counseling, and awareness creation in regular physical activity programs should be integrated into HIV care to prevent and control chronic comorbidity in resource-limited settings.

Patient-centred care: reality or rhetoric—patients’ experiences at ARV clinics located in public hospitals in KwaZulu-Natal, South Africa

Background

The South African public antiretroviral therapy (ART) programme is considered one of the largest and most successful ART programmes worldwide. Hence, a study exploring the patients’ experiences of the public antiretroviral therapy (ART) programme in the second decade of the programme is relevant as no study has been published on patients’ experiences at these sites.

Objectives

To explore patients’ experiences of care in the public ART programme at four ARV clinics within the eThekwini District, KwaZulu-Natal.

Method

A mixed-methods study design with 12 in-depth patient interviews, non-participatory observation, and a stratified random sample of 400 patients completed questionnaires. Qualitative data were thematically analysed. Quantitative data were analysed using a SPSS 24 package to determine frequencies and differences in patients’ responses (p < 0.05). The socio-ecological model framed the study.

Results

All 412 patients reported valuing the provision of free ARVs. Patients’ positive experiences included: routine blood results mostly being available, most staff greeted patients, there were sufficient nurses, patients were satisfied with the time that they spent with doctors, clean clinics, and private and safe counselling areas. The negative experiences included: poor relationships with nurses, negative staff attitudes, disrespectful staff, information was lacking, inadequate counselling at times, varying and inflexible appointments, challenges with data capture and registration systems; varying ARV collection frequencies, routine health tests and processes per site, and the absence of patient committees and representatives.

Conclusion

The results reflected positive and negative experiences which varied between the facilities, as processes and systems differed at each site. Innovative patient-centred processes and programmes could be implemented to ensure patients have mostly positive experiences. As part of continuous improvement, patients’ experiences should be regularly explored to ensure that the ART programme meets their needs and expectations.

Time to Nutritional Recovery and Its Predictors Among Undernourished Adult Patients Living with Human Immune Deficiency Virus Attending Anti-Retroviral Therapy at Public Health Facilities in Southwest Ethiopia. A Multicenter Study

Background

Infection with the human immunodeficiency virus is one of the factors that contribute to malnutrition. Several initiatives have been launched in Ethiopia to improve HIV patients’ nutritional status and achieve early recovery when malnourished patients are found. Despite these efforts, adult HIV patients’ malnutrition recovery remains poor.

Objective

The objective of this study was to assess the time to recovery from undernutrition and associated factors among adult HIV patients on ART at public health facilities in Ilu Aba Bor zone, Southwest Ethiopia, 2021.

Methods

An institution-based retrospective cohort study of 374 adult HIV patients with undernutrition receiving ART at public health institutions in Southwest Ethiopia was conducted. Data were extracted from the patient’s record and entered into Epi-Data version 3.1 before being exported to STATA version 14. The Kaplan–Meier method was used to estimate the time to recovery, and the difference in survival time between predictor variables was tested using the Log rank test. Weibull regression models, both bivariable and multivariable, were fitted. A p-value of 0.05 was declared statistically significant.

Results

The recovery rate was 67.7% and the median recovery time was 65 days (95% CI = 61.6–68.4) and 145 days (95% CI = 130.7–159) for MAM and SAM, respectively. Marital status (Married) (AHR = 0.61; CI = (0.43,0.86)), ART status (pre ART) AHR = 0.492; CI = (0.305,0.793), CD4 (200-350c/m3, AHR = 2.116;CI = (1.447,3.21), type of malnutrition (AHR = 0.22; CI= (0.156,0.307)), ART adherence level (AHR = 3.33, CI = (1.997,5.56)) WHO clinical staging (AHR = 0.685, CI = (0.485,0.948)), sex (male), (AHR = 0.678; CI = (0.509,0.901)) and age (35–54), (AHR = 1.86; CI = (1.408,2.47)) were predictors of recovery time.

Conclusion

Compared to previous studies, the recovery rate was high. SAM, advanced clinical stage, sex, and marital status were all negatively associated with nutritional recovery time, whereas ART adherence, CD4 count, and age were predictors. As a result, a therapeutic feeding program should focus on factors that slow recovery time.

Utility of Obesity Indicators for Predicting Hypertension among Older Persons in Limpopo Province, South Africa

In view of the epidemic proportions of obesity in South Africa and its relationship to cardiometabolic diseases, such as hypertension, a cross sectional study was conducted to investigate the utility of obesity indicators for predicting hypertension among older persons (≥60 years, n = 350) in the Limpopo Province of South Africa. The WHO STEPwise approach was used to collect data on demographic and lifestyle factors. Anthropometrics and blood pressure were measured according to the standard procedures. Receiver operating characteristic curves (ROC) were used to investigate and compare the ability of obesity indicators to predict overall hypertension and either increased systolic (SBP) or increased diastolic (DBP) blood pressure. The area under the ROC curve (AUC) was used to assess a certain indicator’s potential to predict overall hypertension and either increased SBP or increased DBP. Multivariate logistic regression analysis was used to determine the relationship of hypertension with obesity indicators. The mean age of the participants was 69 years (±SD = 7), and hypertension (46%), general obesity (36%) and abdominal obesity (57%) were prevalent among older persons. The obesity indicator body mass index (BMI) (AUC = 0.603 (0.52; 0.69)) was the best predictor of hypertension in older men. Waist circumference (WC) (AUC = 0.640 (0.56; 0.72)) and waist-to-height ratio (WHtR) (AUC = 0.605 (0.52; 0.69)) were better predictors of hypertension than BMI and waist-to-hip ratio (WHR) in older women. After adjustment for risk factors, only WC (AOR = 1.22 (1.16; 1.79)) was significantly associated with hypertension in older women, proposing WC as a screening tool for the prediction of hypertension in South African older women.

Obesity as a Risk Factor for Hypertension and Diabetes among Truck Drivers in a Logistics Company, South Africa

Despite the occupational nature of truckers predisposing them to cardiovascular diseases and risk factors, data is scarce on their prevalence of obesity and its association with developing hypertension (HBP) and diabetes in South Africa. Extracted from the original cross-sectional study of a sample of 312 employees in a logistics company, a census of 96 male truckers was used to determine the prevalence of obesity and its association with HBP and diabetes. WHO STEPwise approach was used to collect data, including systolic (SBP) and diastolic (DBP) blood pressure and anthropometry measurements. HBP is defined as SBP/DBP ≥ 140/90 mmHg, overweight/obesity as BMI ≥ 25 kg/m2, abdominal obesity by waist circumference as WC ≥ 90cm, waist-to-hip-ratio as WHR ≥ 0.90, and waist-to-height ratio as WHtR ≥ 0.5. Data were analysed using SPSS 22. The mean age of truckers was 46 years, 29% were smokers, and 57% alcohol users, while 26% were physically inactive. The prevalence of overweight (44%) and obesity (30%) were observed, while abdominal obesity was high; WC (59%), WHR (65%), and WHtR (80%). HBP (57%) was prevalent and diabetes was 14%. The odds of developing HBP were high for obese truckers by WC [AOR = 4.68; CI = 1.92–11.34)] and by WHtR [AOR = 5.49 CI = 1.74–17.27), while diabetes was associated with WHR (AOR = 1.19; CI = 1.19–31.21). This study showed an associative link between obesity, HBP, and diabetes among the truckers, which is informative for a relevant prevention programme tailored to their needs.

Multilevel Analysis of Urban-Rural Variations of Body Weights and Individual-Level Factors among Women of Childbearing Age in Nigeria and South Africa: A Cross-Sectional Survey

Background: An unhealthy body weight is an adverse effect of malnutrition associated with morbidity among women of childbearing age. While there is increasing attention being paid to the body weights of children and adolescents in Nigeria and South Africa, a major surge of unhealthy body weight in women has received less attention in both countries despite its predominance. The purpose of this study was to explore the prevalence of body weights (underweight, normal, overweight, and obese) and individual-level factors among women of childbearing age by urban-rural variations in Nigeria and South Africa. Methods: This study used the 2018 Nigeria Demographic Health Survey data (n = 41,821) and 2016 South Africa Demographic Health Survey (n = 8514). Bivariate, multilevel, and intracluster correlation coefficient analyses were used to determine individual-level factors associated with body weights across urban-rural variations. Results: The prevalence of being overweight or obese among women was 28.2% and 44.9%, respectively, in South Africa and 20.2% and 11.4% in Nigeria. A majority, 6.8%, of underweight women were rural residents in Nigeria compared to 0.8% in South Africa. The odds of being underweight were higher among women in Nigeria who were unemployed, with regional differences and according to breastfeeding status, while higher odds of being underweight were found among women from poorer households, with differences between provinces and according to cigarette smoking status in South Africa. On the other hand, significant odds of being overweight or obese among women in both Nigeria and South Africa were associated with increasing age, higher education, higher wealth index, weight above average, and traditional/modern contraceptive use. Unhealthy body weights were higher among women in clustering areas in Nigeria who were underweight (intracluster correlation coefficient (ICC = 0.0127), overweight (ICC = 0.0289), and obese (ICC = 0.1040). Similarly, women of childbearing age in clustering areas in South Africa had a lower risk of experiencing underweight (ICC = 0.0102), overweight (ICC = 0.0127), and obesity (ICC = 0.0819). Conclusions: These findings offer a deeper understanding of the close connection between body weights variations and individual factors. Addressing unhealthy body weights among women of childbearing age in Nigeria and South Africa is important in preventing disease burdens associated with body weights in promoting Sustainable Development Goal 3. Strategies for developing preventive sensitization interventions are imperative to extend the perspectives of the clustering effect of body weights on a country level when establishing social and behavioral modifications for body weight concerns in both countries.

Undiagnosed Hypertension in a Workplace: The Case of a Logistics Company in Gauteng, South Africa

A large proportion of the population with hypertension remains undiagnosed, untreated, or inadequately treated, contributing to the rising burden of cardiovascular diseases in South Africa. A workplace may either mitigate or accentuate the risk factors for hypertension. A cross sectional study was conducted to determine the prevalence of undiagnosed hypertension and associated factors among 312 employees in a Logistics Company, South Africa. A modified, validated, self-administered WHO STEPwise questionnaire was used to collect data on demography, lifestyle factors, anthropometry and blood pressure (BP). Hypertension was defined at BP ≥ 140/90 mmHg. Data was analysed using STATA 14. Mean age of employees was 40 ± 10 years, with a 50% prevalence of undiagnosed hypertension. No significant association was observed between occupation and undiagnosed hypertension, except for high prevalence of undiagnosed hypertension among truck drivers and van assistants (43%), and general workers (27%), having higher odds of increased waist-to-height ratio. Hypertension was associated with age (OR = 2.3, 95%CI; 1.21–4.27), alcohol use (AOR = 1.8, 95%CI; 1.05–2.93), waist circumference (AOR = 2.3, 95%CI; 1.29–4.07) and waist-to-height-ratio (AOR = 3.7, 95%CI; 1.85–7.30). Improved and effective workplace health programs and policies are necessary for management of undiagnosed hypertension among employees. Longitudinal studies on mediation of occupation in association of demographic and lifestyle factors with hypertension in workplaces are needed.

Relationship between Endothelial Function, Antiretroviral Treatment and Cardiovascular Risk Factors in HIV Patients of African Descent in South Africa: A Cross-Sectional Study

Limited information on the effect of antiretroviral treatment (ART) on vascular function in South Africans of African descent living with human immunodeficiency virus (HIV) is available. The relationship between ART, vascular function and cardiovascular risk factors in South Africans of African ancestry with HIV was therefore studied. This cross-sectional study recruited 146 HIV-positive individuals on ART (HIV⁺ART⁺), 163 HIV-positive individuals not on ART (HIV⁺ART⁻) and 171 individuals without HIV (HIV⁻) in Mthatha, Eastern Cape Province of South Africa. Flow-mediated dilation (FMD) test was performed to assess endothelial function. Anthropometry and blood pressure parameters were measured. Lipid profile, glycaemic indices, serum creatinine as well as CD4 count and viral load were assayed in blood. Urinary albumin to creatinine ratio (ACR) was determined as a marker of cardiovascular risk. Obesity and albuminuria were positively associated with HIV, and HIV⁺ART⁺ participants had significantly higher HDL cholesterol. Dyslipidaemia markers were significantly higher in hypertensive HIV⁺ART⁺ participants compared with the controls (HIV⁺ART⁻ and HIV⁻ participants). FMD was not different between HIV⁺ART⁺ participants and the controls. Moreover, HIV⁺ART⁺ participants with higher FMD showed lower total cholesterol and LDL cholesterol comparable to that of HIV⁻ and HIV⁺ART⁻ participants. A positive relationship between FMD and CD4 count was observed in HIV⁺ART⁺ participants. In conclusion, antiretroviral treatment was associated with cardiovascular risk factors, particularly dyslipidaemia, in hypertensive South Africans of African ancestry with HIV. Although, ART was not associated with endothelial dysfunction, flow-mediated dilatation was positively associated with CD4 count in HIV-positive participants on ART.
