A systematic review of measures of ability to meet basic needs in older persons.

BACKGROUND: The ability of older persons to meet their basic needs (i.e. personal, financial and housing security), as well as to perform Activities of Daily Living (ADL), is crucial. It is unclear, however, whether such measures exist. This systematic review aimed to review English-language measures of the ability of older persons to meet their basic needs, and to critically review the comprehensiveness of these measures and their psychometric properties. METHODS: Fifteen electronic databases including PubMed, EBSCOhost and CINAHL were systematically searched for studies of measures that assessed the ability of older persons to meet their basic needs, as defined by the World Health Organization. Two review authors independently assessed the studies for inclusion in the review and evaluated their comprehensiveness and psychometrics. RESULTS: We found seven instruments from 62 studies that assessed multi-domain function including ADL and some elements of basic needs. The instruments varied in breadth and in reporting of key psychometric criteria. Further, no single instrument provided a comprehensive assessment of the ability of older persons to meet their basic needs. CONCLUSION: No single instrument that measures the ability to meet basic needs was identified by this review. Further research is needed to develop an instrument that assesses the ability of older persons to meet their basic needs. This measure should include an evaluation of ADL.

HIV and AIDS prevention: knowledge, attitudes, practices and health literacy of older persons in the Western Cape and KwaZulu-Natal Provinces, South Africa and in Lesotho.

BACKGROUND: Population ageing and access to anti-retroviral therapies in South Africa have resulted in ageing of the HIV/AIDS epidemic, which has implications for policy, planning and practice. Impactful interventions on HIV/AIDS for older persons require knowledge on effects of the pandemic on this population. A study was undertaken to assess knowledge, attitudes, and practices (KAP) of HIV/AIDS, as well as health literacy (HL) level of a population aged ≥ 50 years. METHODS: A cross-sectional survey was conducted at three sites in South Africa and two sites in Lesotho with an educational intervention at the South African sites. At baseline, data were collected for assessment of KAP of HIV/AIDS and HL levels. The pre- and post-intervention comprised participants at South African sites being familiarised with the contents of a specially constructed HIV/AIDS educational booklet. Participants' KAP was reassessed six weeks later. A composite score of ≥ 75% was considered adequate KAP and an adequate HL level. RESULTS: The baseline survey comprised 1163 participants. The median age was 63 years (range 50-98 years); 70% were female, and 69% had ≤ 8 years' education. HL was inadequate in 56% and the KAP score was inadequate in 64%. A high KAP score was associated with female gender (AOR = 1.6, 95% CI = 1.2-2.1), age < 65 years (AOR = 1.9, 95% CI = 1.5-2.5) and education level (Primary school: AOR = 2.2; 95% CI = 1.4-3.4); (High school: AOR = 4.4; 95% CI = 2.7-7.0); (University/college: AOR = 9.6; 95% CI = 4.7-19.7). HL was positively associated with education but no association with age or gender. The educational intervention comprised 614 (69%) participants. KAP scores increased post intervention: 65.2% of participants had adequate knowledge, versus 36% pre-intervention. Overall, younger age, being female and higher education level were associated with having adequate knowledge about HIV/AIDS, both pre- and post-intervention. CONCLUSIONS: The study population had low HL, and KAP scores regarding HIV/AIDS were poor but improved following an educational intervention. A tailored educational programme can place older people centrally in the fight against the epidemic, even in the presence of low HL. Policy and educational programmes are indicated to meet the information needs of older persons, which are commensurate with the low HL level of a large section of that population.

Dementia subtypes, cognitive decline and survival among older adults attending a memory clinic in Cape Town, South Africa: a retrospective study.

BACKGROUND: There are no published longitudinal studies from Africa of people with dementia seen in memory clinics. The aim of this study was to determine the proportions of the different dementia subtypes, rates of cognitive decline, and predictors of survival in patients diagnosed with dementia and seen in a memory clinic. METHODS: Data were collected retrospectively from clinic records of patients aged ≥ 60 seen in the memory clinic at Groote Schuur Hospital, Cape Town, South Africa over a 10-year period. Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria were used to identify patients with Major Neurocognitive Disorders (dementia). Additional diagnostic criteria were used to determine the specific subtypes of dementia. Linear regression analysis was used to determine crude rates of cognitive decline, expressed as mini-mental state examination (MMSE) points lost per year. Changes in MMSE scores were derived using mixed effects modelling to curvilinear models of cognitive change, with time as the dependent variable. Multivariable cox survival analysis was used to determine factors at baseline that predicted mortality. RESULTS: Of the 165 patients who met inclusion criteria, 117(70.9%) had Major Neurocognitive Disorder due to Alzheimer's disease (AD), 24(14.6%) Vascular Neurocognitive Disorder (VND), 6(3.6%) Dementia with Lewy Bodies (DLB), 5(3%) Parkinson disease-associated dementia (PDD), 3(1.8%) fronto-temporal dementia, 4(2.4%) mixed dementia and 6(3.6%) other types of dementia. The average annual decline in MMSE points was 2.2(DLB/PDD), 2.1(AD) and 1.3(VND). Cognitive scores at baseline were significantly lower in patients with 8 compared to 13 years of education and in those with VND compared with AD. Factors associated with shorter survival included age at onset greater than 65 (HR = 1.82, 95% C.I. 1.11, 2.99, p = 0.017), lower baseline MMSE (HR = 1.05, 95% C.I. 1.01, 1.10, p = 0.029), Charlson's comorbidity scores of 3 to 4 (HR = 1.88, 95% C.I. 1.14, 3.10, p = 0.014), scores of 5 or more (HR = 1.97, 95% C.I. 1.16, 3.34, p = 0.012) and DLB/PDD (HR = 3.07, 95% C.I. 1.50, 6.29, p = 0.002). Being female (HR = 0.59, 95% C.I.0.36, 0.95, p = 0.029) was associated with longer survival. CONCLUSIONS: Knowledge of dementia subtypes, the rate and factors affecting cognitive decline and survival outcomes will help inform decisions about patient selection for potential future therapies and for planning dementia services in resource-poor settings.

Understanding factors associated with sarcopenic obesity in older African women from a low-income setting: a cross-sectional analysis.

BACKGROUND: High rates of food insecurity, obesity and obesity-related comorbidities in ageing South African (SA) women may amplify the risk of developing sarcopenic obesity. This study aimed to investigate the prevalence and correlates of sarcopenic obesity and its diagnostic components [grip strength, appendicular skeletal muscle mass (ASM) and body mass index (BMI)] in older SA women from a low-income setting. METHODS: This cross-sectional study recruited black SA women between the ages of 60-85 years (n = 122) from a low-income community. Testing included a fasting blood sample (markers of cardiometabolic risk, HIV), whole body and regional muscle and fat mass (dual-energy absorptiometry x-ray), anthropometry, blood pressure, functional movement tests, current medication use, demographic and health questionnaires, physical activity (PA; accelerometery), household food insecurity access scale, and a one-week quantified food frequency questionnaire. Foundation for the National Institutes of Health (FNIH) criteria (grip strength and ASM, adjusted for BMI) were used to classify sarcopenia. Participants with sarcopenia alongside a BMI of > 30.0 kg/m2 were classified as having sarcopenic obesity. Prevalence using other criteria (European Working Group on Sarcopenia in Older People, Asian Working Group for Sarcopenia and the International Working Group for Sarcopenia) were also explored. RESULTS: The prevalence of sarcopenia was 27.9%, which comprised of sarcopenia without obesity (3.3%) and sarcopenic obesity (24.6%). Other classification criteria showed that sarcopenia ranged from 0.8-14.7%, including 0.8-9.8% without obesity and 0-4.9% with sarcopenic obesity. Using multivariate-discriminant analysis (OPLS-DA) those with sarcopenic obesity presented with a descriptive profile of higher C-reactive protein, waist circumference, food security and sedentary time than women without sarcopenic obesity (p = 0.046). A similar profile described women with low BMI-adjusted grip strength (p < 0.001). CONCLUSIONS: The majority of women with sarcopenia were also obese (88%). We show a large discrepancy in the diagnostic criteria and the potential for significantly underestimating the prevalence of sarcopenia if BMI is not adjusted for. The main variables common to women with sarcopenic obesity were higher food security, lower PA and chronic inflammation. Our data highlights the importance of addressing obesity within these low-income communities to ensure the prevention of sarcopenic obesity and that quality of life is maintained with ageing.

Chronic Noncommunicable Diseases in 6 Low- and Middle-Income Countries: Findings From Wave 1 of the World Health Organization's Study on Global Ageing and Adult Health (SAGE).

In this paper, we examine patterns of self-reported diagnosis of noncommunicable diseases (NCDs) and prevalences of algorithm/measured test-based, undiagnosed, and untreated NCDs in China, Ghana, India, Mexico, Russia, and South Africa. Nationally representative samples of older adults aged ≥50 years were analyzed from wave 1 of the World Health Organization's Study on Global Ageing and Adult Health (2007-2010; n = 34,149). Analyses focused on 6 conditions: angina, arthritis, asthma, chronic lung disease, depression, and hypertension. Outcomes for these NCDs were: 1) self-reported disease, 2) algorithm/measured test-based disease, 3) undiagnosed disease, and 4) untreated disease. Algorithm/measured test-based prevalence of NCDs was much higher than self-reported prevalence in all 6 countries, indicating underestimation of NCD prevalence in low- and middle-income countries. Undiagnosed prevalence of NCDs was highest for hypertension, ranging from 19.7% (95% confidence interval (CI): 18.1, 21.3) in India to 49.6% (95% CI: 46.2, 53.0) in South Africa. The proportion untreated among all diseases was highest for depression, ranging from 69.5% (95% CI: 57.1, 81.9) in South Africa to 93.2% (95% CI: 90.1, 95.7) in India. Higher levels of education and wealth significantly reduced the odds of an undiagnosed condition and untreated morbidity. A high prevalence of undiagnosed NCDs and an even higher proportion of untreated NCDs highlights the inadequacies in diagnosis and management of NCDs in local health-care systems.

Risk factors for falls in older adults in a South African Urban Community.

BACKGROUND: Studies on falls in older adults have mainly been conducted in high income countries. Scant, if any, information exists on risk factors for falls in the older population of sub-Saharan African countries. METHODS: A cross-sectional survey and a 12-month follow-up study were conducted to determine risk factors for falls in a representative multi-ethnic sample of 837 randomly selected ambulant community-dwelling subjects aged ≥65 years in three suburbs of Cape Town, South Africa. Logistic regression models were fitted to determine the association between (1) falls and (2) recurrent falls occurring during follow-up and their potential socio-demographic, self-reported medical conditions and physical assessment predictors. RESULTS: Prevalence rates of 26.4 % for falls and 11 % for recurrent falls at baseline and 21.9 % for falls and 6.3 % for recurrent falls during follow-up. In both prospective analyses of falls and recurrent falls, history of previous falls, dizziness/vertigo, ethnicity (white or mixed ancestry vs black African) were significant predictors. However, poor cognitive score was a significant predictor in the falls analysis, and marital status (unmarried vs married) and increased time to perform the timed Up and Go test in the recurrent fall analysis but not in both. Other than the timed Up and Go test in recurrent falls analysis, physical assessment test outcomes were not significant predictors of falls. CONCLUSION: Our study provides simple criteria based on demographic characteristics, medical and physical assessments to identify older persons at increased risk of falls. History taking remains an important part of medical practice in the determination of a risk of falls in older patients. Physical assessment using tools validated in developed country populations may not produce results needed to predict a risk of falls in a different setting.

A Delphi study to guide the development of a clinical indicator tool for palliative care in South Africa.

BACKGROUND:  The South African National Policy Framework and Strategy on Palliative Care (NPFSPC) recommends that when integrating palliative care (PC) into the health system, a PC indicators tool should be used to guide clinicians to recognise a patient who should receive PC. The policy document recommends 'a simple screening tool developed for use in South Africa that would assist healthcare professionals (HCPs) to recognise patients who may have unmet palliative care needs'. AIM:  This research study sought to develop South African consensus on indicators for PC to assist clinicians to recognise a patient in need of PC. SETTING:  The South African healthcare setting. METHODS:  A Delphi study was considered suitable as a methodology to develop consensus. The methodology was based on the Conducting and REporting of DElphi studies (CREDES) guidance on Delphi studies to ensure rigour and transparency in conducting and reporting. Six different Delphi rounds were used to develop consensus. Each round allowed participants to anonymously rate statements with predefined rating scales. RESULTS:  Cognisant of the disparities in healthcare provision and access to equitable healthcare in South Africa, the expert advisory group recommended, especially for South Africa, that 'this tool is for deteriorating patients with an advanced life-limiting illness where all available and appropriate management for underlying illnesses and reversible complications has been offered'. The expert advisory group felt that disease-specific indicators should be described before the general indicators in the South African indicators tool, so all users of the tool orientate themselves to the disease categories first. This study included three new domains to address the South African context: trauma, infectious diseases and haematological diseases. General indicators for PC aligned with the original Supportive and Palliative Care Indicators Tool (SPICT) tool. CONCLUSION:  The Supportive and Palliative Care Indicators Tool for South Africa (SPICTTM-SA) is a simple screening tool for South Africa that may assist HCPs to recognise patients who may have unmet PC needs.

Societal Need for Interdisciplinary Ageing Research: An International Alliance of Research Universities "Ageing, Longevity and Health" Stream (IARU-ALH) Position Statement.

Ageing is a global concern with major social, health, and economic implications. While individual countries seek to develop responses to immediate, pressing needs, international attention and collaboration is required to most effectively address the multifaceted challenges and opportunities an ageing global population presents in the longer term. The Ageing, Longevity and Health stream of the International Alliance of Research Universities (IARU-ALH) was built on a solid foundation of first-class interdisciplinary research and on innovative outreach and communication centres. This interdisciplinary network conducts projects that span biology, medicine, social sciences, epidemiology, public health, policy, and demography, and actively engages with the public and other societal stakeholders. Here we posit that such international interdisciplinary networks are needed and uniquely placed to address major challenges related to health and ageing and ultimately will produce new understanding and knowledge to promote the awareness of healthy ageing and encourage societal change via novel, science-informed interventions. Global interdisciplinary research presents great potential and opportunities to accelerate our understanding of human ageing and to produce new, more effective solutions to a pressing, complex problem. However, more focused, strategic efforts and investments are required in order to deliver on these potentials and reap maximum benefits for individuals and societies. IARU-ALH members are determined to contribute, in collaboration with others, to delivering on this vision.

Sarcopenic Obesity in Africa: A Call for Diagnostic Methods and Appropriate Interventions.

This perspective aims to highlight the lack of current knowledge on sarcopenic obesity in Africa and to call for diagnostic methods and appropriate interventions. Sarcopenic obesity has been defined as obesity that occurs in combination with low muscle mass and function, which is typically evident in older adults. However, there has been no clear consensus on population-specific diagnostic criterion, which includes both gold-standard measures that can be used in a more advanced health care system, and surrogate measures that can be used in low-income settings with limited resources and funding. Importantly, low and middle-income countries (LMICs) across Africa are in an ongoing state of economic and social transition, which has contributed to an increase in the aging population, alongside the added burden of poverty, obesity, and associated co-morbidities. It is anticipated that alongside the increased prevalence of obesity, these countries will further experience an increase in age-related musculoskeletal diseases such as sarcopenia. The developmental origins of health and disease (DOHaD) approach will allow clinicians and researchers to consider developmental trajectories, and the influence of the environment, for targeting high-risk individuals and communities for treatment and/or prevention-based interventions that are implemented throughout all stages of the life course. Once a valid and reliable diagnostic criterion is developed, we can firstly assess the prevalence and burden of sarcopenic obesity in LMICs in Africa, and secondly, develop appropriate and sustainable interventions that target improved dietary and physical activity behaviors throughout the life course.

Does social support effect knowledge and diabetes self-management practices in older persons with Type 2 diabetes attending primary care clinics in Cape Town, South Africa?

BACKGROUND: In South Africa with one of the most rapidly ageing populations in Africa despite the demographic impact of the HIV/AIDS epidemic, diabetes is a major cause of morbidity and mortality. Self-management is challenging for all those with the condition but is likely to create a higher demand for those who may have existing co-morbidities associated with age, and long-standing chronic diseases. OBJECTIVE: To determine the relationship of social support, especially that of family and friends with their self-management. METHODS: This cross-sectional study was undertaken in the Cape Town metropole primary care clinics. The sample comprised 406 people drawn from four community health centres (CHC) that are served by Groote Schuur Hospital at the tertiary level. RESULTS: Of the 406 participants, 68.5% were females, 60.5% were living with a family member, and almost half were married. The mean duration of diabetes from diagnosis was eight years. More than half (57.4%) had no or only primary education. Half the participants (50.2%) had poor knowledge level in relation to symptoms and complications of diabetes. Multivariable linear regression showed older age was associated with poor knowledge (®: -1.893, 95% CI-3.754; -0.031) and higher income was associated with self-management practice (®: 3.434, 95% CI 0.797; 6.070). Most participants received family support to follow aspects of diabetes self-management. The ordinal logistic regression indicated that family support was positively associated with the self-management practice score for following a diabetic meal plan, taking care of feet, physical activity, testing blood sugar and handling participants' feelings about being diabetic, but not for taking medication. CONCLUSIONS: Consideration needs to be given to developing and testing education programmes that focus on needs of older people with diabetes and emphases the role of family and friends.

Older persons' experience with health care at two primary level clinics in Cape Town, South Africa: a qualitative assessment.

BACKGROUND: Efficient methods of assessing older persons' healthcare needs are required in busy public sector primary healthcare clinics in South Africa. These clinics are the main points of entry into the healthcare system. This study was part of a larger study to test the local applicability and adaptability of the World Health Organization's (WHO) Age Friendly Primary Care Toolkit for assessing and managing chronic diseases and common geriatric syndromes. AIM: To assess how older persons experience healthcare delivery at two primary healthcare clinics, and identify perceived gaps in health care to older people. DESIGN & SETTING: A qualitative study at two primary healthcare sites in the suburbs of Cape Town, South Africa. METHOD: Focus group discussions (two at each facility) using an interview guide. RESULTS: Analysed data were categorised into five themes: 'despite the challenges, there is overall good care'; 'communication gaps and the frustration of feeling unheard'; 'the health service is experienced as being unreliable, stretched, and is difficult to access'; 'there is a perception of pervasive structural ageism in the clinics'; and 'there is a perception that the quality of care received is related to the profession of the healthcare provider'. CONCLUSION: Challenges of access and care for older clients at primary care clinics are linked to their age-specific holistic needs, which are not fully met by the current age-friendly arrangements. Measures should be taken at the clinics to complement the perceived good clinical care received, by improving access to care, making care appropriate to the need, reducing waiting times, and creating opportunities for older persons to feel respected and heard.

The effectiveness of peer and community health worker-led self-management support programs for improving diabetes health-related outcomes in adults in low- and-middle-income countries: a systematic review.

OBJECTIVE: Community-based peer and community health worker-led diabetes self-management programs (COMP-DSMP) can benefit diabetes care, but the supporting evidence has been inadequately assessed. This systematic review explores the nature of COMP-DSMP in low- and middle-income countries' (LMIC) primary care settings and evaluates implementation strategies and diabetes-related health outcomes. METHODS: We searched the Cochrane Library, PubMed-MEDLINE, SCOPUS, CINAHL PsycINFO Database, International Clinical Trials Registry Platform, Clinicaltrials.gov, Pan African Clinical Trials Registry (PACTR), and HINARI (Health InterNetwork Access to Research Initiative) for studies that evaluated a COMP-DSMP in adults with either type 1 or type 2 diabetes in World Bank-defined LMIC from January 2000 to December 2019. Randomised and non-randomised controlled trials with at least 3 months follow-up and reporting on a behavioural, a primary psychological, and/or a clinical outcome were included. Implementation strategies were analysed using the standardised implementation framework by Proctor et al. Heterogeneity in study designs, outcomes, the scale of measurements, and measurement times precluded meta-analysis; thus, a narrative description of studies is provided. RESULTS: Of the 702 records identified, eleven studies with 6090 participants were included. COMP-DSMPs were inconsistently associated with improvements in clinical, behavioural, and psychological outcomes. Many of the included studies were evaluated as being of low quality, most had a substantial risk of bias, and there was a significant heterogeneity of the intervention characteristics (for example, peer definition, selection, recruitment, training and type, dose, and duration of delivered intervention), such that generalisation was not possible. CONCLUSIONS: The level of evidence of this systematic review was considered low according to the GRADE criteria. The existing evidence however does show some improvements in outcomes. We recommend ongoing, but well-designed studies using a framework such as the MRC framework for the development and evaluation of complex interventions to inform the evidence base on the contribution of COMP-DSMP in LMIC.

A survey of trainee specialists experiences at the University of Cape Town (UCT): impacts of race and gender.

BACKGROUND: Efforts to redress racial and gender inequalities in the training of medical specialists has been a central part of a dedicated programme in the Faculty of Health Sciences at the University of Cape Town (UCT). This study aimed to describe trends in race and gender profiles of postgraduate students in medical specialties (registrars) from 1999 to 2006 and to identify factors affecting recruitment and retention of black and female trainees. METHOD: Review of faculty databases for race and gender data from 1999 to 2006. Distribution of an anonymous self-administered questionnaire to all registrars in 2005/2006. RESULTS: The percentage of African registrars doubled from 10% to 19% from 1999 to beyond 2002. The percentages of Africans, Coloureds and Indians rose steadily from 26% to 46% from 1999 to 2005, as did that of women from 27% to 44%. The institution's perceived good reputation, being an alumnus and originating from Cape Town were common reasons for choosing UCT for training. A quarter of respondents reported knowledge of a friend who decided against studying at UCT for reasons which included anticipated racial discrimination. Black respondents (23%), particularly African (50%), were more likely to describe registrarship at UCT as unwelcoming than white respondents (12%). Specific instances of personal experience of discrimination were uncommon and not associated with respondents' race or gender. Registrars who had had a child during registrarship and those reporting discrimination were more likely to rate the learning and research environment as poor (Odds Ratio, 4.01; 95% CI 0.98 - 16.47 and 1.99 95% CI 0.57 - 6.97, respectively). CONCLUSION: The proportion of black and female registrars at the University of Cape Town has increased steadily from 1999 to 2006, most likely a result of systematic equity policies and procedures adopted in the faculty during this period. The data point to a need for policies to make the institution more welcoming to diversity and for strategies to address institutional culture and mentorship, with an aim to develop examples of best practices to share within and between institutions.

Current policies and practices for the provision of diabetes care and self-management support programmes for older South Africans.

BACKGROUND: One of the most important primary health challenges currently affecting older people in South Africa (SA) is the increasing prevalence of non-communicable disease (NCD). Research is needed to investigate the current state of care and self-management support available to older diabetic patients in SA and the potential for interventions promoting self-management and community involvement. AIM: This study aimed to review current policies, programmes and any other interventions as they relate to older people with diabetes with a view to assess the potential for the development of a self-management programme for older persons attending public sector primary health care services in Cape Town, South Africa. SETTING: Eighteen community health centres (CHCs) formed the sampling frame for the study. METHODS: This study aimed to review current policies and programmes as they relate to older people with diabetes. It involved a documentary review and qualitative individual interviews with key informants in the health services and Department of Health. RESULTS: Several national initiatives have sought to advance the health of older people, but they have only been partially successful. There are however multiple efforts to re-orientate the health-care system to focus more effectively on NCDs, which benefit older patients with diabetes. The establishment of community-based services to provide self-management support, promote health and ease access to medicine helps overcome many of the commonly cited barriers to care experienced by older patients. What may be equally important is that practitioners gain the communication skills and educational resources to effectively educate and counsel patients on lifestyle behaviour change and self-care management. CONCLUSION: This article alerts policy-makers and clinicians to some of the specific issues considered to be pertinent and important in the care and management of older diabetic patients. Many of these would also be applicable to older patients with other chronic conditions.

Diabetes in South African older adults: prevalence and impact on quality of life and functional disability - as assessed using SAGE Wave 1 data.

BACKGROUND: Diabetes is a chronic disease with severe late complications. It is known to impact the quality of life and cause disability, which may affect an individual's capacity to manage and maintain longer-term health and well-being. OBJECTIVES: To examine the prevalence of self-report diabetes, and association between diabetes and each of health-related quality of life and disability amongst South Africa's older adults. To study both the direct relationship between diabetes and these two measures, as well as moderation effects, i.e. whether associations between other factors and these measures of well-being differed between individuals with diabetes and those without. METHODS: Secondary analyses of data on participants aged 50 years and older from the Study on global AGEing and adult health (SAGE) in South Africa Wave 1 (2007-2008) were conducted. Prevalence of self-reported diabetes was assessed. Multivariable regressions describe the relationships between each of quality of life (WHOQoL) and disability (WHODAS), and diabetes, while controlling for selected socio-demographic characteristics, health risk behaviours and co-morbid conditions. In the regression models, we also investigated whether diabetes moderates the relationships between these additional factors and WHOQoL/WHODAS. RESULTS: Self-reported diabetes prevalence was 9.2% (95% CI: 7.8,10.9) and increased with age. Having diabetes was associated with poorer WHOQoL scores (additive effect: -4.2; 95% CI: -9.2,0.9; p-value <0.001) and greater disability (multiplicative effect: 2.1; 95% CI: 1.5,2.9; p-value <0.001). Lower quality of life and greater disability were both related to not being in a relationship, lower education, less wealth, lower physical activity and a larger number of chronic conditions. CONCLUSIONS: Diabetes is associated with lower quality of life and greater disability amongst older South Africans. Attention needs to be given to enhancing the capacity of health systems to meet the changing needs of ageing populations with diabetes in SA as well as facilitating social support networks in communities.

Methodological challenges in a study on falls in an older population of Cape Town, South Africa.

BACKGROUND: Falls are a major cause of disability, morbidity and mortality in older persons, but have been under researched in developing countries. OBJECTIVE: To describe challenges encountered in a community-based study on falls in a multi-ethnic population aged ≥65 years in a low-income setting. METHODS: The study was conducted in four stages: A pilot study (n=105) to establish a sample size for the survey. An equipment validation study (n=118) to use for fall risk determination. A cross-sectional baseline (n=837) and a 12-month follow-up survey (n=632) to establish prevalence and risk factors for falls. RESULTS: Prevalence rate of 26.4% (95% CI 23.5-29.5%) and risk factors for recurrent falls: previous falls, self-reported poor mobility and dizziness were established. Adaptations to the gold standard prospective fall research study design were employed: 1) to gain access to the study population in three selected suburbs, 2) to perform assessments in a non-standardised setting, 3) to address subjects' poverty and low literacy levels, and high attrition of subjects and field workers. CONCLUSION: Studies on falls in the older population of low- to middle-income countries have methodological challenges. Adaptive strategies used in the Cape Town study and the research experience reported may be instructive for investigators planning similar studies in such settings.

Health expenditure and catastrophic spending among older adults living with HIV.

INTRODUCTION: The burden of HIV is increasing among adults aged over 50, who generally experience increased risk of cormorbid illnesses and poorer financial protection. We compared patterns of health utilisation and expenditure among HIV-positive and HIV-negative adults over 50. METHODS: Data were drawn from the Study on global AGEing and adult health in South Africa with analysis focusing on individual and household-level data of 147 HIV-positive and 2725 HIV-negative respondents. RESULTS: HIV-positive respondents reported lower utilisation of private health-care facilities (11.8%) than HIV-negative respondents (25.0%) (p = .03) and generally had more negative attitudes towards health system responsiveness than HIV-negative counterparts. Less than 10% of HIV-positive and HIV-negative respondents experienced catastrophic health expenditure (CHE). Women (OR 1.8; p < .001) and respondents from rural settings (OR 2.9; p < .01) had higher odds of CHE than men or respondents in urban settings. Over half the respondents in both groups indicated that they had received free health care. CONCLUSIONS: These findings suggest that although HIV-positive and HIV-negative older adults in South Africa are protected to some extent from CHE, inequalities still exist in access to and quality of care available at health-care services - which can inform South Africa's development of a national health insurance scheme.

Use of physical restraint in hospital patients: A descriptive study in a tertiary hospital in South Africa.

BACKGROUND: The use of physical restraint in patient management is a common and emotive issue, and has legal and ethical dimensions. OBJECTIVE: To document the prevalence of physical restraint use, patient characteristics associated with physical restraint use, and nurses' and doctors' knowledge and perceptions towards the practice. METHODS: A cross-sectional study of 572 patients, of whom 132 were physically restrained, was conducted in acute wards of a tertiary hospital. Data were collected on the 132 physically restrained patients. Fifty-nine doctors and 159 nurses completed a specially constructed questionnaire. Descriptive statistics were derived and expressed as numbers and percentages. RESULTS: Prevalence of restraint use was 23% (132/572). The distribution in acute wards was: medical 54.5%; surgical 44.7%; maternity 0.8%; psychiatry none. Mean age (SD) of the restrained patients was 49 years (20.5); 53.8% were male. The commonest types of restraints used were bed rails 93% and wrist belts 12%. Restraints were used largely to protect medical devices and as protection from harm. Less than 15% of the nurses reported having received training and 36% of the doctors reported having received some guidance on the use of restraints. Only a minority of nurses and doctors knew of a hospital policy on restraint use. Documentation on the prescription and indication for the use of restraint was poor. CONCLUSION: Prevalence of restraint use is high and poorly coordinated. A policy on the use of restraint and comprehensive guidelines should be developed to guide health care practitioners in the management of patients where restraint cannot be avoided.

Effectiveness of community-based peer-led diabetes self-management programmes (COMP-DSMP) for improving clinical outcomes and quality of life of adults with diabetes in primary care settings in low and middle-income countries (LMIC): a systematic review and meta-analysis.

INTRODUCTION: Globally, an estimated 380 million people live with diabetes today--80% in low-income and middle-income countries. The Middle East, Western Pacific, Sub-Saharan Africa and South-East Asia remain the most affected regions where economic development has transformed lifestyles, people live longer and there is an increase in the adult population. Although peer support has been used in different conditions with varied results, yet there is limited evidence to date supporting its effectiveness, particularly for individuals with diabetes. In this review, we will focus on community-based peer-led diabetes self-management programmes (COMP-DSMP) and examine the implementation strategies and diabetes-related health outcomes associated with them in LMIC primary healthcare settings. METHODS AND ANALYSIS: In accordance with reporting equity-focused systematic reviews PRISMA-P (preferred reporting items for systematic review and meta-analysis protocols 2015 checklist) guidelines, a systematic review with meta-analysis of randomised controlled trials (RCTs), non-randomised controlled trials, quasi-randomised controlled trials (CCTs) that involve contact with an individual or group of peers (paid or voluntary). Electronic searches will be performed in The Cochrane Library, MEDLINE, PubMed, SCOUPS, CINAHL and PsycINFO Database for the period January up to July 2000 along with manual searches in the reference lists of relevant papers. The analyses will be performed based on baseline data from RCTs, CCTs and preintervention and postintervention means or proportions will be reported for both intervention and control groups, and the absolute change from baseline will be calculated, together with 95% CIs. For dichotomous outcomes, the relative risk of the outcome will be presented compared to the control group. The risk difference will be calculated, which is the absolute difference in the proportions in each treatment group. ETHICS AND DISSEMINATION: Ethics is not required for this study, given that this is a protocol for a systematic review, which utilises published data. The findings of this study will be widely disseminated through peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBER: PROSPERO (2014:CRD42014007531).

Falls and fall prevention programmes in developing countries: environmental scan for the adaptation of the Canadian Falls prevention curriculum for developing countries.

PROBLEM: Falls in older persons in developing countries are poorly understood, and falls prevention and health promotion programmes for this population are largely lacking. METHODS: A systematic review was carried out of relevant literature on falls and prevention programmes, and falls prevention education, and a scan undertaken of health promotion programmes for older persons in a representative country - South Africa. RESULTS: Studies on the risk and prevalence of falls are largely retrospective and hospital-based, with varied methodology, including study period, sampling method and sample size. Falls prevalence is based largely on self-reports in studies on general trauma in all age groups. Falls incidence varies from 10.1% to 54%. No reports could be traced on sustained falls prevention or health promotion programmes. CONCLUSION: Scant research has been conducted and little preventive education offered on falls in older persons. Adaptation of the Canadian Falls Prevention Curriculum for developing countries will help to fill gaps in knowledge and practice. IMPACT ON INDUSTRY: With rapid increase in the populations of older persons in developing countries, research on age related disorders such as falls is required to guide policy and management of falls.
