Self-reported health and health care use in an ageing population in the Agincourt sub-district of rural South Africa.

BACKGROUND: South Africa is experiencing a demographic and epidemiological transition with an increase in population aged 50 years and older and rising prevalence of non-communicable diseases. This, coupled with high HIV and tuberculosis prevalence, puts an already weak health service under greater strain. OBJECTIVE: To measure self-reported chronic health conditions and chronic disease risk factors, including smoking and alcohol use, and to establish their association with health care use in a rural South African population aged 50 years or older. METHODS: The Study on Global Ageing and Adult Health (SAGE), in collaboration with the INDEPTH Network and the World Health Organization, was implemented in the Agincourt sub-district in rural northeast South Africa where there is a long-standing health and socio-demographic surveillance system. Household-based interviews were conducted in a random sample of people aged 50 years and older. The interview included questions on self-reported health and health care use, and some physical measurements, including blood pressure and anthropometry. RESULTS: Four hundred and twenty-five individuals aged 50 years or older participated in the study. Musculoskeletal pain was the most prevalent self-reported condition (41.7%; 95% Confidence Interval [CI] 37.0-46.6) followed by hypertension (31.2%; 95% CI 26.8-35.9) and diabetes (6.1%; 95% CI 4.1-8.9). All self-reported conditions were significantly associated with low self-reported functionality and quality of life, 57% of participants had hypertension, including 44% of those who reported normal blood pressure. A large waist circumference and current alcohol consumption were associated with high risk of hypertension in men, whereas in women, old age, high waist-hip ratio, and less than 6 years of formal education were associated with high risk of hypertension. Only 45% of all participants reported accessing health care in the last 12 months. Those who reported higher use of the health facilities also reported lower levels of functioning and quality of life. CONCLUSIONS: Self-reported chronic health conditions, especially hypertension, had a high prevalence in this population and were strongly associated with higher levels of health care use. The primary health care system in South Africa will need to provide care for people with non-communicable diseases

Evolving temporal conceptual schemas: the reification case

We study temporal conceptual schema evolutions related to reification, a typical and complex modeling construct. Various types of reification are considered. Using a previously defined framework, we specify only at conceptual level (and without descending to logical or application levels), the effects of any possible evolution related to reification, thus reducing the complexity of the management of those changes.Peer ReviewedPostprint (published version

Pensions, consumption and health: Evidence from rural South Africa

Background: Increasing numbers of older people in sub-Saharan Africa are gaining access to pension benefits and it is often claimed that these benefits promote healthy forms of consumption, which contribute to significant improvements in their health status. However, evidence to support these claims is limited. Methods: The paper uses data for 2701 people aged 60 or over who participated in a population-based study in rural north-eastern South Africa. It analyses effects of receiving a pension on reported food scarcity, body mass index and patterns of consumption. Results: The paper finds that living in a pension household is associated with a reduced risk of reported food scarcity and with higher levels of consumption of food and drink. The paper does not find that living in a pension household is associated with a higher prevalence of current smoking nor current alcohol consumption. However, the paper still finds that tobacco and alcohol make up over 40% of reported food and drink consumption, and that the correlation between reported food scarcity and body mass index status is imperfect. Conclusions: The paper does not show significant associations between pension receipt and the selected risk factors. However, the context of prevalent obesity and high shares of household spending allocated to tobacco and alcohol call into question widely-made claims that pensions enhance healthy consumption among older people in low and middle-income countries

Premarital Births and Union Formation in Rural South Africa.

CONTEXT: In rural South Africa, women often delay union formation until they are in their late 20s, though premarital first births are common. METHODS: Longitudinal data from the Agincourt Health and Socio-Demographic Surveillance System in rural South Africa were used to examine the relationship between premarital birth and union entry among 55,158 nonmigrant women aged 10-35 who took part in at least one annual census from 1993 to 2012. Discrete-time event history models were used to determine whether the likelihood of union formation differed between women who had had a premarital first birth and those who had not. Associations between single motherhood and union type (marriages or nonmarital partnerships) were identified using logistic regression. RESULTS: Forty-five percent of women had had a premarital first birth and 25% had entered a first union. Women who had had a premarital first birth were less likely than other women to have entered a first union (odds ratio, 0.6). Women who had had a premarital birth in the past year were more likely than those without a premarital birth to have entered a union (1.5), but women had reduced odds of union formation if they had had a birth 1-2 years earlier (0.9) or at least five years earlier (0.8). Unions formed within two years of a premarital birth had an elevated likelihood of being nonmarital partnerships (1.2-1.4). CONCLUSIONS: Single motherhood is common in the Agincourt HDSS, and women with a premarital first birth face challenges in establishing committed unions with partners

Mobile phone use among patients and health workers to enhance primary healthcare : a qualitative study in rural South Africa

Mobile phones have the potential to improve access to healthcare information and services in low-resourced settings. This study investigated the use of mobile phones among patients with chronic diseases, pregnant women, and health workers to enhance primary healthcare in rural South Africa. Qualitative research was undertaken in Mpumalanga in 2014. Semi structured in-depth interviews were conducted with 113 patients and 43 health workers from seven primary healthcare clinics and one district hospital. Data were thematically analysed. We found that some health workers and patients used their own mobile phones for healthcare, bearing the cost themselves. Patients used their mobile phones to remind themselves to take medication or attend their clinic visits, and they appreciated receiving voice call reminders. Some patients and health workers accessed websites and used social media to gather health information, but lacked web search strategies. The use of the websites and social media was intermittent due to lack of financial ability to afford airtime among these patients and health workers. Many did not know what to search for and where to search. Doctors have developed their own informal mobile health solutions in response to their work needs and lack of resources due to their rurality. Physical and social factors influence the usability of mobile phones for healthcare, and this can shape communication patterns such as poor eyesight. The bottom-up use of mobile phones has been evolving to fill the gaps to augment primary care services in South Africa; however, barriers to access remain, such as poor digital infrastructure and low digital literacy

Task shifting to improve the provision of integrated chronic care: realist evaluation of a lay health worker intervention in rural South Africa

Introduction Task shifting is a potential solution to the shortage of healthcare personnel in low/middle-income countries, but contextual factors often dilute its effectiveness. We report on a task shifting intervention using lay health workers to support clinic staff in providing chronic disease care in rural South Africa, where the HIV epidemic and an ageing population have increased demand for care. Methods We conducted a realist evaluation in a cluster randomised controlled trial. We conducted observations in clinics, focus group discussions, in-depth interviews and patient exit interviews, and wrote weekly diaries to collect data. Results All clinic managers had to cope with an increasing but variable patient load and unplanned staff shortages, insufficient space, poorly functioning equipment and erratic supply of drugs. These conditions inevitably generated tension among staff. Lay health workers relieved the staff of some of their tasks and improved care for patients, but in some cases the presence of the lay health worker generated conflict with other staff. Where managers were able to respond to the changing circumstances, and to contain tension among staff, facilities were better able to meet patient needs. This required facility managers to be flexible, consultative and willing to act on suggestions, sometimes from junior staff and patients. While all facilities experienced an erratic supply of drugs and poorly maintained equipment, facilities where there was effective management, teamwork and sufficient space had better chronic care processes and a higher proportion of patients attending on their appointed day. Conclusion Lay health workers can be valuable members of a clinic team, and an important resource for managing increasing patient demand in primary healthcare. Task shifting will only be effective if clinic managers respond to the constantly changing system and contain conflict between staff. Strengthening facility-level management and leadership skills is a priority. Trial registration number ISRCTN12128227

Pensions and Low Sodium Salt:A Qualitative Evaluation of a New Strategy for Managing Hypertension in Rural South Africa

BACKGROUND: This paper describes a pilot study to assess the feasibility of a novel intervention to improve the management of hypertension among older people in rural South Africa. Older South Africans have the highest rates of uncontrolled hypertension recorded for any country. Notably, South Africa has a widely-available old age grant (pension), which is delivered on a monthly basis to citizens living in rural villages.  METHODS: We assessed the feasibility of engaging with older people at the point of pension delivery in the Agincourt sub-district of Mpumalanga Province. This included providing information about hypertension, measuring blood pressure, referral to primary care services, and providing a monthly supply of low sodium salt. We recruited 20 people aged 60 and over to participate in the pilot intervention, which was conducted over three months in two villages. Towards the end of the intervention, we conducted focus groups with study participants and held a meeting with local stakeholders, including the district health office and the state social security agency.  RESULTS: The pilot study demonstrated (i) Sustained engagement with the original 20 participants. Of these, 19 continued to participate in the intervention during subsequent monthly pension days. (ii) A high level of acceptance of the low sodium salt product reflected in repeat usage and comments made in the focus groups. (iii) Strong support for the intervention and a willingness to collaborate with local stakeholders. (iv) A perception among participants that symptoms they associated with hypertension had abated. This is supported by blood pressure readings made over the three months of follow-up.  CONCLUSION: Though limited in scope, this pilot study provided evidence of the feasibility of the intervention and justification for it to be tested on a larger and more robust basis
