Inequalities and factors associated with adherence to diabetes self-care practices amongst patients at two public hospitals in Gauteng, South Africa.

BACKGROUND: Self- management is vital to the control of diabetes. This study aims to assess the diabetes self-care behaviours of patients attending two tertiary hospitals in Gauteng, South Africa. The study also seeks to estimate the inequalities in adherence to diabetes self-care practices and associated factors. METHODS: A unique health-facilities based cross-sectional survey was conducted amongst diabetes patients in 2017. Our study sample included 396 people living with diabetes. Face-to-face interviews were conducted using a structured questionnaire. Diabetes self-management practices considered in this study are dietary diversity, medication adherence, physical activity, self-monitoring of blood-glucose, avoiding smoking and limited alcohol consumption. Concentration indices (CIs) were used to estimate inequalities in adherence to diabetes self-care practices. Multiple logistic regressions were fitted to determine factors associated with diabetes self-care practices. RESULTS: Approximately 99% of the sample did not consume alcohol or consumed alcohol moderately, 92% adhered to self-monitoring of blood-glucose, 85% did not smoke tobacco, 67% adhered to their medication, 62% had a diverse diet and 9% adhered to physical activity. Self-care practices of dietary diversity (CI = 0.1512) and exercise (CI = 0.1067) were all concentrated amongst patients with higher socio-economic status as indicated by the positive CIs, whilst not smoking (CI = - 0.0994) was concentrated amongst those of lower socio-economic status as indicated by the negative CI. Dietary diversity was associated with being female, being retired and higher wealth index. Medication adherence was found to be associated with older age groups. Physical activity was found to be associated with tertiary education, being a student and those within higher wealth index. Self-monitoring of blood glucose was associated with being married. Not smoking was associated with being female and being retired. CONCLUSION: Adherence to exercising, dietary diversity and medication was found to be sub-optimal. Dietary diversity and exercise were more prevalent among patients with higher socio-economic status. Our findings suggest that efforts to improve self- management should focus on addressing socio-economic inequalities. It is critical to develop strategies that help those within low-socio-economic groups to adopt healthier diabetes self-care practices.

Incidence, socio-economic inequalities and determinants of catastrophic health expenditure and impoverishment for diabetes care in South Africa: a study at two public hospitals in Tshwane.

BACKGROUND: Direct out of pocket (OOP) payments for healthcare may cause financial hardship. For diabetic patients who require frequent visits to health centres, this is of concern as OOP payments may limit access to healthcare. This study assesses the incidence, socio-economic inequalities and determinants of catastrophic health expenditure and impoverishment amongst diabetic patients in South Africa. METHODS: Data were taken from a cross-sectional survey conducted in 2017 at two public hospitals in Tshwane, South Africa (N = 396). Healthcare costs and transport costs related to diabetes care were classified as catastrophic if they exceeded the 10% threshold of household's capacity to pay (WHO standard method) or if they exceeded a variable threshold of total household expenditure (Ataguba method). Erreygers concentration indices (CIs) were used to assess socio-economic inequalities. A multivariate logistic regression was applied to identify the determinants of catastrophic health expenditure and impoverishment. RESULTS: Transport costs contributed to over 50% of total healthcare costs. The incidence of catastrophic health expenditure was 25% when measured at a 10% threshold of capacity to pay and 13% when measured at a variable threshold of total household expenditure. Depending on the method used, the incidence of impoverishment varied from 2 to 4% and the concentration index for catastrophic health expenditure varied from - 0.2299 to - 0.1026. When measured at a 10% threshold of capacity to pay factors associated with catastrophic health expenditure were being female (Odds Ratio 1.73; Standard Error 0.51), being within the 3rd (0.49; 0.20), 4th (0.31; 0.15) and 5th wealth quintile (0.30; 0.17). When measured using a variable threshold of total household expenditure factors associated with catastrophic health expenditure were not having children (3.35; 1.82) and the 4th wealth quintile (0.32; 0.21). CONCLUSION: Financial protection of diabetic patients in public hospitals is limited. This observation suggests that health financing interventions amongst diabetic patients should target the poor and poor women in particular. There is also a need for targeted interventions to improve access to healthcare facilities for diabetic patients and to reduce the financial impact of transport costs when seeking healthcare. This is particularly important for the achievement of universal health coverage in South Africa.

Subjective social status and inequalities in depressive symptoms: a gender-specific decomposition analysis for South Africa.

BACKGROUND: Inequalities in mental health are a notable and well documented policy concern in many countries, including South Africa. Individuals' perception of their position in the social hierarchy is strongly and negatively related to their mental health, whilst the global burden of poor mental health is greater amongst women. This paper offers a first glimpse of the factors that shape gender-based health inequalities across subjective social status. METHODS: This study employs the cross-sectional 2014 South African Social Attitudes Survey (SASAS). The prevalence of depressive symptoms is measured with the aid of the CES-D 8-item scale, with analyses disaggregated by gender. Concentration indices (CI) are used to measure inequalities in depressive symptoms related to subjective social status. The study applies the Wagstaff decomposition to determine the factors that contribute to these gender-based inequalities. RESULTS: More than 26% of the study sample had depressive symptoms (95% CI 24.92-28.07). The prevalence of depressive symptoms is significantly more pronounced in females (28.46% versus 24.38%; p = 0.011). The concentration index for depressive symptoms is - 0.276 (95% CI -0.341 - - 0.211), showing large inequalities across subjective social status. The observed SSS-related inequality in depressive symptoms however is higher for males (CI = -0.304) when compared to females (CI = -0.240) (p = 0.056). The most important contributor to SSS-related inequalities in depressive symptoms, at 61%, is subjective social status itself (contributing 82% in females versus 44% in males). Other variables that make large contributions to the inequalities in depressive symptoms at 11% each are race (contributing 2% in females versus 25% in males) and childhood conflict (contributing 17% in females versus 4% in males). CONCLUSION: Policy makers should target a reduction in the positive contribution of SSS to depression via the implementation of programmes that improve social welfare. Given the much greater contribution to inequalities among females, these policies should target women. Policies that protect children and especially the girl child from conflict can also be useful in reducing inequalities in depression related to subjective social status during adulthood. Overall, there is need for a multi-sectoral approach to address these inequalities.

Cost of diabetes mellitus in Africa: a systematic review of existing literature.

BACKGROUND: There is an increasing recognition that non communicable diseases impose large economic costs on households, societies and nations. However, not much is known about the magnitude of diabetes expenditure in African countries and to the best of our knowledge no systematic assessment of the literature on diabetes costs in Africa has been conducted. The aim of this paper is to capture the evidence on the cost of diabetes in Africa, review the methods used to calculate costs and identify areas for future research. METHODS: A desk search was conducted in Pubmed, Medline, Embase, and Science direct as well as through other databases, namely Google Scholar. The following eligibility criteria were used: peer reviewed English articles published between 2006 and 2016, articles that reported original research findings on the cost of illness in diabetes, and studies that covered at least one African country. Information was extracted using two data extraction sheets and results organized in tables. Costs presented in the studies under review are converted to 2015 international dollars prices (I$). RESULTS: Twenty six articles are included in this review. Annual national direct costs of diabetes differed between countries and ranged from I$3.5 billion to I$4.5 billion per annum. Indirect costs per patient were generally higher than the direct costs per patient of diabetes. Outpatient costs varied by study design, data source, perspective and healthcare cost categories included in the total costs calculation. The most commonly included healthcare items were drug costs, followed by diagnostic costs, medical supply or disposable costs and consultation costs. In studies that reported both drug costs and total costs, drug costs took a significant portion of the total costs per patient. The highest burden due to the costs associated with diabetes was reported in individuals within the low income group. CONCLUSION: Estimation of the costs associated with diabetes is crucial to make progress towards meeting the targets laid out in Sustainable Development Goal 3 set for 2030. The studies included in this review show that the presence of diabetes leads to elevated costs of treatment which further increase in the presence of complications. The cost of drugs generally contributed the most to total direct costs of treatment. Various methods are used in the estimation of diabetes healthcare costs and the costs estimated between countries differ significantly. There is room to improve transparency and make the methodologies used standard in order to allow for cost comparisons across studies.

Self-reported diabetes during pregnancy in the South African National Health and Nutrition Examination Survey: extent and social determinants.

BACKGROUND: Diabetes is a serious and growing public health concern in South Africa, but its prevalence and distribution in pregnant women is not well known. Women diagnosed with diabetes during pregnancy have a substantially greater risk of adverse health outcomes for both mother and child. This study aims to determine the prevalence and social determinants of diabetes during pregnancy in South Africa. METHODS: Data used in this study were from the 2012 South African National Nutrition and Health Examination Survey; a nationally representative cross-sectional household survey. The analysis was restricted to girls and women between the ages of 15 to 49 years who self-reported ever being pregnant (n = 4261) Logistic regression models were constructed to analyse the relationship between diabetes during pregnancy and several indicators including race, family history of diabetes, household income, area of residence and obesity. RESULTS: The prevalence of diabetes during pregnancy in South Africa was 3% (144 women) of all women who reported ever being pregnant. The majority of the women who had ever had diabetes were African (70%), 51% were unemployed and 76% lived in rural areas. Factors strongly associated with diabetes during pregnancy were age (1.04 [Odds Ratio], 0.01 [Standard Error]), family history of diabetes (3.04; 0.8) and race (1.91; 0.53). CONCLUSION: The analysis will contribute to an understanding of the prevalence of diabetes during pregnancy and its social determinants. This will help in the development of effective interventions targeted at improving maternal and child health for mothers at high risk.

The extent and determinants of diabetes and cardiovascular disease comorbidity in South Africa - results from the South African National Health and Nutrition Examination Survey (SANHANES-1).

BACKGROUND: Diabetes is a major health problem and cause of death worldwide. It is predicted that the prevalence of diabetes will increase from 415 million in 2015 to 642 million in 2040. However, the burden of diabetes in low- and middle-income countries is not clearly understood, particularly its interaction with other chronic illnesses. This study investigates the self-reported prevalence of and factors associated with diabetes and cardiovascular comorbidity in South Africa. METHODS: Data used in this study are from the 2012 South African National Health and Nutrition Examination Survey; a nationally representative cross-sectional household survey (N = 25,532). Diabetes and cardiovascular disease comorbidity was defined as the coexistence of diabetes plus one or more cardiovascular diseases reported at the time of the survey. This study makes use of multinomial logistic regression models to analyse the relationship between diabetes - cardiovascular disease comorbidity and several predictors including race, income, socio-economic status and obesity. RESULTS: According to the survey data we analysed, 5% of South Africans aged 15 and above had self-reported diabetes in 2011-2012. Among those with self-reported diabetes, 73% had at least one additional cardiovascular chronic illness. Diabetes and its cardiovascular disease comorbidity was more prevalent in Africans (66%), females (66%), those who lived in urban areas (75%), had secondary education (44%) and were unemployed (62%). Factors strongly associated with diabetes - cardiovascular disease comorbidity were older age (Odds ratio [OR] 1.09; 95% Confidence Interval [CI] 1.06-1.12), high household income (0.27; 0.10-0.76) versus low income, moderate (0.33; 0.11-0.96) and good self-rated health (0.24; 0.08-0.68) versus bad self-rated health, occasional (0.29; 0.10-0.88) and regular smokers (0.25; 0.12-0.53) versus non-smokers and physical activity (0.15; 0.03-0.68) versus no physical activity. CONCLUSION: The study provides insight into the factors associated with cardiovascular disease comorbidity in diabetic individuals. The findings indicate that there are differences in the factors associated with diabetes and those associated with diabetes - cardiovascular disease comorbidity. This provides information, which can be used to design programmes that encourage healthy lifestyles in people living with diabetes.

A randomized trial of 'fresh start' text messaging to improve return to care in people with HIV who missed appointments in South Africa.

OBJECTIVE: Treatment interruptions are a barrier to successful antiretroviral therapy (ART). 'Fresh start messages', which leverage significant days on the calendar (e.g., new year, public holiday) in order to prompt action, have the potential to encourage people with HIV (PWH) to return to care. We evaluated a 'fresh start' intervention (text messages) to increase return to care in PWH who had missed their last appointment. DESIGN: A three arm 1 : 1:1 individual randomised controlled trial. METHODS: We randomized adults in Capricorn District who had missed ART appointments by >28 days to: no text message; unframed messages (fresh start not mentioned); or framed messages (fresh start mentioned). Randomization was stratified by treatment interruption duration and across two holidays (Youth Day, Mandela Day). The primary outcome was an ART-related clinic visit at ≤45 days of the first message. RESULTS: 9143 participants were randomised. For Youth Day, 1474 and 1468 were sent unframed and framed messages respectively, with 13.4% sent these messages having an ART visit vs. 11.9% not sent a message [adjusted odds ratio (aOR) 1.2; 95% confidence interval (CI): 1.0-1.4, P -value = 0.075]. For Mandela Day, 1336 and 1334 were sent unframed and framed messages respectively, with 6.7% sent these messages having an ART-related clinic visit vs. 5.4% not sent a message (aOR 1.2; 95% CI: 1.0-1.6; P -value = 0.100). CONCLUSIONS: Low-cost text messages sent around a 'fresh start' date may increase the likelihood that patients who miss appointments return to care. This study suggests the potential of text messaging for motivating return to care.

Determinants of Deteriorated Self-Perceived Health Status among Informal Settlement Dwellers in South Africa.

Self-perceived health (SPH) is a widely used measure of health amongst individuals that indicates an individual's overall subjective perception of their physical or mental health status. As rural to urban migration increases, the health of individuals within informal settlements becomes an increasing concern as these people are at high health and safety risk due to poor housing structures, overcrowding, poor sanitation and lack of services. This paper aimed to explore factors related to deteriorated SPH status among informal settlement dwellers in South Africa. This study used data from the first national representative Informal Settlements Survey in South Africa conducted by the Human Sciences Research Council (HSRC) in 2015. Stratified random sampling was applied to select informal settlements and households to participate in the study. Multivariate logistic regression and multinomial logistic regression analyses were performed to assess factors affecting deteriorated SPH among the informal settlement dwellers in South Africa. Informal settlement dwellers aged 30 to 39 years old (OR = 0.332 95%CI [0.131-0.840], p < 0.05), those with ZAR 5501 and more household income per month (OR = 0.365 95%CI [0.144-0.922], p < 0.05) and those who reported using drugs (OR = 0.069 95%CI [0.020-0.240], p < 0.001) were significantly less likely to believe that their SPH status had deteriorated compared to the year preceding the survey than their counterparts. Those who reported always running out of food (OR = 3.120 95%CI [1.258-7.737], p < 0.05) and those who reported having suffered from illness or injury in the past month preceding the survey (OR = 3.645 95%CI [2.147-6.186], p < 0.001) were significantly more likely to believe that their SPH status had deteriorated compared to the year preceding the survey than their counterparts. In addition, those who were employed were significantly (OR = 1.830 95%CI [1.001-3.347], p = 0.05) more likely to believe that their SPH status had deteriorated compared to the year preceding the survey than those who were unemployed with neutral SPH as a base category. Overall, the results from this study point to the importance of age, employment, income, lack of food, drug use and injury or illness as key determinants of SPH amongst informal settlement dwellers in South Africa. Given the rapid increasing number of informal settlements in the country, our findings do have implications for better understanding the drivers of deteriorating health in informal settlements. It is therefore recommended that these key factors be incorporated into future planning and policy development aimed at improving the standard of living and health of these vulnerable residents.

Outcomes of a model integrating tuberculosis testing into COVID-19 services in South Africa.

The coronavirus disease 2019 (COVID-19) pandemic led to a reordering of healthcare priorities. Health resources were turned to the screening and diagnosis of COVID-19, leading to a reduction in tuberculosis (TB) testing and treatment initiation. An innovative model that integrated TB and COVID-19 services was adopted at primary care facilities in Johannesburg Health District, Gauteng. This short report illustrates results from this model's implementation in two facilities. Patients were screened for COVID-19 at a single point of entry and separated according to screening result. Self-reported human immunodeficiency virus (HIV) status, symptom, and symptom duration were then used to determine TB risk amongst those screening positive for COVID-19. Data from clinical records were extracted. Approximately 9% of patients with a positive symptom screen (n = 76) were sent for a TB test and 84% were sent for a COVID-19 test. Amongst those sent for a TB test, 8% (n = 6) had TB detected, and amongst those sent for a COVID-19 test, 18% (n = 128) were positive. Amongst those with COVID-19-related symptoms, 15% (n = 130) presented with a cough or fever and were known HIV positive and 121 (93%) of these were sent for a COVID-19 test and 31 (24%) were sent for a TB test. Given the HIV prevalence and symptoms in our study, our results show lower-than-expected TB tests conducted.Contribution: Our study documents the outcomes of an innovative way to combine operational workflows for TB and COVID-19. This provides a starting point for countries seeking to integrate TB and COVID-19 screening and testing.

Outcomes of a Telephonic Postnatal Intervention for Mothers and Babies in Mopani District, Limpopo, South Africa.

Background: The postnatal period is a critical period for the health of both mother and infant. Studies show that postnatal care reduces neonatal mortality and other adverse mother and child health outcomes. While the World Health Organization recommends four postnatal care contacts, South African guidelines only specify three, excluding a 7-14-day post-birth contact. This study aimed to assess whether a telephonic contact at 7-14 days following delivery had any effect on use of additional postnatal services. Methods: A randomized controlled trial design was used to address the study objectives. Two groups of new mothers were randomly allocated to either receive the 7-14-day telephonic contact or not from a research nurse. Data for this study was collected at Maphutha L Malatjie Hospital (MLMH). Descriptive analysis was performed first, then a multivariable logistic regression analysis was conducted to assess the factors associated with access to other health care services. Results: A total of 882 mothers were recruited, 854 (97%) were classified as high risk, 28 (3%) were classified as low risk. 417 (49%) of the high risk received the 7-14-day call (intervention group) whilst the remainder of 437 (51%) from the high risk plus all mothers classified as low risk (28) did not receive the call (control group). 686 (78%) of all mothers received the 3 month follow up call. The call showed that 17 mothers from the control group and 10 mothers from the intervention group accessed other healthcare services. We find that hypertension (3.28; 1.06 -10.10), mental health risk (2.82; 1.25 -6.38), PV bleeding during pregnancy (18.33; 1.79-187.61), problem during labor (4.40; 1.280-15.13) were positively associated with access to other health services, with statistically significant associations (p-value < 0.05). We found statistically insignificant associations between receiving the 7-14-day call and accessing other health care services. Conclusion: The 7-14-day call had no statistically significant impact on access to other health services, however, high levels of satisfaction with the call may point to an unmet need for care at this time. It is important to investigate other innovative solutions to postnatal care improvement in South Africa.

Risk profile of postnatal women and their babies attending a rural district hospital in South Africa.

Background: Maternal and neonatal mortality remain unacceptably high and inequitably distributed in South Africa, with the postnatal period being a dangerous time for both mother and baby. The aim of this paper is to describe the risk factors for poor postnatal outcomes, including postnatal mental health disorders, in a population of postnatal women and their babies utilising rural district hospital services in Limpopo Province, with a focus on HIV. We also describe health care provider compliance with relevant guidelines. Methods: All women discharged from the postnatal ward of the district hospital who consented to participate were enrolled. A research nurse used a structured questionnaire to collect data about sociodemographic information, pregnancy and pre-existing conditions, complications during labour and birth, pregnancy outcomes and mental health risk factors. Results: The questionnaire was completed for 882 women at the time of discharge. Only 354 (40.2%) of participants had completed secondary education, and 105 (11.9%) reported formal employment. Chronic hypertension was recorded in 20 women (2.3%), with an additional 49 (5.6%) developing a hypertensive disorder during pregnancy. HIV prevalence was 22.8%. 216 women (24.5%) had a mental health risk factor, with 40 reporting more than one (4.5%). Having no income, no antenatal care, having HIV and any hypertensive disorder were significantly associated with a positive mental health risk screen in multivariable analysis. There were 31 stillbirths and early neonatal deaths (3.5%), and 119 babies (13.4%) were born at a low birth weight. Stillbirth or early neonatal death was significantly associated with no antenatal care in multivariable analysis. Conclusions: Women and babies in this study experienced multiple risk factors for poor outcomes in the postpartum period. Postnatal care should be strengthened in order to address the dominant risks to mothers and babies, including socioeconomic challenges, HIV and hypertension, and risks to mental health. Tools to identify mothers and babies at risk of postnatal complications would allow limited resources to be allocated where they are most needed.

Access to and Satisfaction with Basic Services in Informal Settlements: Results from a Baseline Assessment Survey.

Subjective responses of satisfaction with basic services delivery is an indicator of service delivery performance. This study provides an overview of the status of basic service delivery and determines the factors associated with service delivery satisfaction within informal settlements targeted for upgrading in South Africa. A multinomial logistic regression was used to analyze the relationship between satisfaction with basic services of water, sanitation, refuse and electricity with several predictors including individual factors, household factors, community factors and service-related factors. The most common source of drinking water, toilet facility and refuse disposal method were communal tap (55%) pit latrine (53%) and local authorities (34%), respectively. Approximately 52% of the respondents in the study reported not having access to electricity. Results also show that satisfaction in basic services delivery varies and is influenced by service-related factors. Interventions targeted at improving the quality of basic service provided are essential to meet the targets set out in the sustainable development goals.

Lifestyle and socio-economic inequalities in diabetes prevalence in South Africa: A decomposition analysis.

BACKGROUND: Inequalities in diabetes are widespread and are exacerbated by differences in lifestyle. Many studies that have estimated inequalities in diabetes make use of self-reported diabetes which is often biased by differences in access to health care and diabetes awareness. This study adds to this literature by making use of a more objective standardised measure of diabetes in South Africa. The study estimates socio-economic inequalities in undiagnosed diabetes, diagnosed diabetes (self-reported), as well as total diabetes (undiagnosed diabetics + diagnosed diabetics). The study also examines the contribution of lifestyle factors to diabetes inequalities in South Africa. METHODS: This cross sectional study uses data from the 2012 South African National Health and Nutrition Examination Survey (SANHANES-1) and applies the Erreygers Concentration Indices to assess socio-economic inequalities in diabetes. Contributions of lifestyle factors to inequalities in diabetes are assessed using a decomposition method. RESULTS: Self-reported diabetes and total diabetes (undiagnosed diabetics + diagnosed diabetics) were significantly concentrated amongst the rich (CI = 0.0746; p < 0.05 and CI = 0.0859; p < 0.05). The concentration index for undiagnosed diabetes was insignificant but pro-poor. The decomposition showed that lifestyle factors contributed 22% and 35% to socioeconomic inequalities in self-reported and total diabetes, respectively. CONCLUSION: Diabetes in South Africa is more concentrated amongst higher socio-economic groups when measured using self-reported diabetes or clinical data. Our findings also show that the extent of inequality is worse in the total diabetes outcome (undiagnosed diabetics + diagnosed diabetics) when compared to the self-reported diabetes outcome. Although in comparison to other determinants, the contribution of lifestyle factors was modest, these contributions are important in the development of policies that address socio-economic inequalities in the prevalence of diabetes.

Understanding the determinants of hemoglobin and iron status: adolescent-adult women comparisons in SANHANES-1.

The study compared hemoglobin (Hb) and serum ferritin levels between adolescent and adult women with different body mass indices, dietary intake, and sociodemography. A secondary analysis of data for 3177 South African women ⩾15 years of age who participated in the SANHANES-1 study was undertaken. Abnormal Hb (≤12 g/dL) and serum ferritin (<15 µg/mL) were based on the World Health Organization's criteria for nonpregnant women aged ⩾15 years. Data were analyzed using STATA version 11. Overall, anemia was detected in 740 (23.3%) participants. Of the individuals in the subsample (n = 1123, 15-35 years) who had serum ferritin measured, 6.0% presented with iron depletion (ID) and 10.8% presented with iron-deficiency anemia (IDA). The highest prevalences of anemia, ID, and IDA were in 15- to 18-year-olds (11.2%, 8.8%, and 20.2%, respectively). Black young adults (19-24 years) were up to 40 times more likely to present with ID compared with their non-black counterparts. While overweight adolescents were three times more likely to be anemic, overweight and obese young adults, as well as obese older adults (25-35 years), were less likely to be anemic compared with normal-weight women of all age groups. Overconsumption of dietary fat increased ID by up to 54- and 11-fold (adolescents and 25- to 35-year-olds, respectively). In South Africa, anemia is most prevalent in adolescents and black women. Anemia is also an indicator of overconsumption of dietary fat and a marker of socioeconomic disadvantage.
