Exploring biochar and Moringa oleifera seed proteins for greywater remediation on small farms.

This study investigated the potential of using biochar and Moringa oleifera seed proteins for sustainable greywater treatment in rural Kenya. Greywater samples from washing clothes were collected from households in the Kenyan counties of Kwale and Siaya. Two treatment methods, batch stirring and filtration, were used to assess the effectiveness of using biochar and Moringa oleifera seed protein extract together to treat greywater at a household level. Both methods achieved a significant reduction in contaminants: colour was reduced by up to 43% in Kwale and 67% in Siaya, turbidity decreased by 91-98%, and surfactant levels were lowered by 89-93%. There were increases in total organic carbon and total dissolved solids post-treatment, but both methods effectively reduced levels of phosphates, nitrates and iron. This research highlights the potential of using locally available materials for greywater treatment and provides insights into sustainable water management nature-based solutions in the Global South.

Factors Influencing Progressive Utilization of Palliative Care Services among Cancer Patients in Kenya: The Case of Nairobi Hospice.

The rising cases of non-communicable diseases, specifically cancer, have led to the integration of palliative care in their management. However, only 10% of cancer patients have access to palliative care. Healthcare utilization is an important step in disease management as it aids individuals in accessing opportunities for the prevention and treatment of diseases. The study applied the binary probit model to estimate the progressive utilization of palliative care services by cancer patients. The aim of the study was to determine factors influencing the progressive utilization of palliative care by cancer patients. A cross-sectional data survey was conducted for 169 cancer patients seeking palliative care at the Nairobi Hospice in 2013. For each patient, the predisposing, enabling, and need (PEN) factors were analyzed as key criteria for applying progressive utilization of palliative care at the Nairobi Hospice as compared to those residing in other counties in the study. Descriptive statistics showed that 27% of patients studied resided in Nairobi County, where 61% were female, 62% were married, 35% had primary education, 44% were self-employed, and 59% had medical insurance. Probit regression and marginal effects showed that employment and religion were significant in determining the progressive utilization of palliative care. Employment status and religion are consequently the main factors that both governments and health-focused non-governmental organizations need to consider increasing the probability of progressively utilizing palliative care to improve the quality of life of cancer patients.

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.

Access to Information Technologies and Consumption of Fruits and Vegetables in South Africa: Evidence from Nationally Representative Data.

Extensive evidence indicates that fruit and vegetable (F+V) consumption leads to reduced chances of diet related non-communicable diseases (NCDs). However, the F+V consumption levels remain low. This paper investigates the extent to which access to information technologies improves F+V consumption in South Africa. A nationally representative sample of 20,908 households was analysed using the Poisson and logit regression models. The study results indicated that most households do not consume sufficient F+V per day. Only 26% of the household heads consumed F+V at least five times a day. Access to mobile phones, radio, television, and internet was associated with increasing frequency of F+V consumption, and higher chances that a household would consume the minimum recommended levels. The association between the communication technologies and F+V consumption varied. Television access had the highest association with both foods, while internet was only significantly associated with vegetable consumption. Several demographic and socio-economic factors played a key role in shaping F+V consumption patterns. The results show that there is scope to disseminate nutrition awareness and education programs, through mobile phones, internet, radio and television in South Africa. The interventions to promote F+V consumption should be tailored according to the different socio-economic profiles of the population.

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.

Multi-sectoral action in non-communicable disease prevention policy development in five African countries.

BACKGROUND: The rise of non-communicable diseases (NCDs) in Africa requires a multi-sectoral action (MSA) in their prevention and control. This study aimed to generate evidence on the extent of MSA application in NCD prevention policy development in five sub-Saharan African countries (Kenya, South Africa, Cameroon, Nigeria and Malawi) focusing on policies around the major NCD risk factors. METHODS: The broader study applied a multiple case study design to capture rich descriptions of policy contents, processes and actors as well as contextual factors related to the policies around the major NCD risk factors at single- and multi-country levels. Data were collected through document reviews and key informant interviews with decision-makers and implementers in various sectors. Further consultations were conducted with NCD experts on MSA application in NCD prevention policies in the region. For this paper, we report on how MSA was applied in the policy process. RESULTS: The findings revealed some degree of application of MSA in NCD prevention policy development in these countries. However, the level of sector engagement varies across different NCD policies, from passive participation to active engagement, and by country. There was higher engagement of sectors in developing tobacco policies across the countries, followed by alcohol policies. Multi-sectoral action for tobacco and to some extent, alcohol, was enabled through established structures at national levels including inter-ministerial and parliamentary committees. More often coordination was enabled through expert or technical working groups driven by the health sectors. The main barriers to multi-sectoral action included lack of awareness by various sectors about their potential contribution, weak political will, coordination complexity and inadequate resources. CONCLUSION: MSA is possible in NCD prevention policy development in African countries. However, the findings illustrate various challenges in bringing sectors together to develop policies to address the increasing NCD burden in the region. Stronger coordination mechanisms with clear guidelines for sector engagement are required for effective MSA in NCD prevention. Such a mechanisms should include approaches for capacity building and resource generation to enable multi-sectoral action in NCD policy formulation, implementation and monitoring of outcomes.

Non-communicable disease prevention policy process in five African countries.

BACKGROUND: The increasing burden of non-communicable diseases (NCDs) in sub-Saharan Africa is causing further burden to the health care systems that are least equipped to deal with the challenge. Countries are developing policies to address major NCD risk factors including tobacco use, unhealthy diets, harmful alcohol consumption and physical inactivity. This paper describes NCD prevention policy development process in five African countries (Kenya, South Africa, Cameroon, Nigeria, Malawi), including the extent to which WHO "best buy" interventions for NCD prevention have been implemented. METHODS: The study applied a multiple case study design, with each country as a separate case study. Data were collected through document reviews and key informant interviews with national-level decision-makers in various sectors. Data were coded and analyzed thematically, guided by Walt and Gilson policy analysis framework that examines the context, content, processes and actors in policy development. RESULTS: Country-level policy process has been relatively slow and uneven. Policy process for tobacco has moved faster, especially in South Africa but was delayed in others. Alcohol policy process has been slow in Nigeria and Malawi. Existing tobacco and alcohol policies address the WHO "best buy" interventions to some extent. Food-security and nutrition policies exist in almost all the countries, but the "best buy" interventions for unhealthy diet have not received adequate attention in all countries except South Africa. Physical activity policies are not well developed in any study countries. All have recently developed NCD strategic plans consistent with WHO global NCD Action Plan but these policies have not been adequately implemented due to inadequate political commitment, inadequate resources and technical capacity as well as industry influence. CONCLUSION: NCD prevention policy process in many African countries has been influenced both by global and local factors. Countries have the will to develop NCD prevention policies but they face implementation gaps and need enhanced country-level commitment to support policy NCD prevention policy development for all risk factors and establish mechanisms to attain better policy outcomes while considering other local contextual factors that may influence policy implementation such as political support, resource allocation and availability of local data for monitoring impacts.

Influence of the WHO framework convention on tobacco control on tobacco legislation and policies in sub-Saharan Africa.

BACKGROUND: The World Health Organization's Framework Convention on Tobacco Control, enforced in 2005, was a watershed international treaty that stipulated requirements for signatories to govern the production, sale, distribution, advertisement, and taxation of tobacco to reduce its impact on health. This paper describes the timelines, context, key actors, and strategies in the development and implementation of the treaty and describes how six sub-Saharan countries responded to its call for action on tobacco control. METHODS: A multi-country policy review using case study design was conducted in Cameroon, Kenya, Nigeria, Malawi, South Africa, and Togo. All documents related to the WHO Framework Convention on Tobacco Control and individual country implementation of tobacco policies were reviewed, and key informant interviews related to the countries' development and implementation of tobacco policies were conducted. RESULTS: Multiple stakeholders, including academics and activists, led a concerted effort for more than 10 years to push the WHO treaty forward despite counter-marketing from the tobacco industry. Once the treaty was enacted, Cameroon, Kenya, Nigeria, Malawi, South Africa, and Togo responded in unique ways to implement tobacco policies, with differences associated with the country's socio-economic context, priorities of country leaders, industry presence, and choice of strategies. All the study countries except Malawi have acceded to and ratified the WHO tobacco treaty and implemented tobacco control policy. CONCLUSIONS: The WHO Framework Convention on Tobacco Control provided an unprecedented opportunity for global action against the public health effects of tobacco including non-communicable diseases. Reviewing how six sub-Saharan countries responded to the treaty to mobilize resources and implement tobacco control policies has provided insight for how to utilise international regulations and commitments to accelerate policy impact on the prevention of non-communicable diseases.

The evolution of non-communicable diseases policies in post-apartheid South Africa.

BACKGROUND: Redressing structural inequality within the South African society in the post-apartheid era became the central focus of the democratic government. Policies on social and economic transformation were guided by the government's blueprint, the Reconstruction and Development Programme. The purpose of this paper is to trace the evolution of non-communicable disease (NCD) policies in South Africa and the extent to which the multi-sectoral approach was utilised, while explicating the underlying rationale for "best buy" interventions adopted to reduce and control NCDs in South Africa. The paper critically engages with the political and ideological factors that influenced design of particular NCD policies. METHODS: Through a case study design, policies targeting specific NCD risk factors (tobacco smoking, unhealthy diets, harmful use of alcohol and physical inactivity) were assessed. This involved reviewing documents and interviewing 44 key informants (2014-2016) from the health and non-health sectors. Thematic analysis was used to draw out the key themes that emerged from the key informant interviews and the documents reviewed. RESULTS: South Africa had comprehensive policies covering all the major NCD risk factors starting from the early 1990's, long before the global drive to tackle NCDs. The plethora of NCD policies is attributable to the political climate in post-apartheid South Africa that set a different trajectory for the state that was mandated to tackle entrenched inequalities. However, there has been an increase in prevalence of NCD risk factors within the general population. About 60% of women and 30% of men are overweight or obese. While a multi-sectoral approach is part of public policy discourse, its application in the implementation of NCD policies and programmes is a challenge. CONCLUSIONS: NCD prevalence remains high in South Africa. There is need to adopt the multi-sectoral approach in the implementation of NCD policies and programmes.

Assessment of the multi-sectoral approach to tobacco control policies in South Africa and Togo.

BACKGROUND: Tobacco use is the world's leading preventable cause of illness and death and the most important risk factor for non-communicable diseases (NCDs), particularly cardiovascular and chronic respiratory diseases (heart attack, stroke, congestive obstructive pulmonary disease, and lung cancer). Tobacco control is one of the World Health Organization's "best-buys" interventions to prevent NCDs. This study assessed the use of a multi-sectoral approach (MSA) in developing and implementing tobacco control policies in South Africa and Togo. METHODS: This two-country case study consisted of a document review of tobacco control policies and of key informant interviews (N = 56) about the content, context, stakeholders, and strategies employed throughout policy formulation and implementation in South Africa and Togo. To guide our analysis, we used the Comprehensive Framework for Multi-Sectoral Approach to Health Policy, which is built around four major constructs of context, content, stakeholders and strategies. RESULTS: The findings show that the formulation of tobacco control policies in both countries was driven locally by the political, historical, social and economic contexts, and globally by the adoption WHO Framework Convention on Tobacco Control (FCTC). In both countries, the health department led policy formulation and implementation. The stakeholders involved in South Africa were more diverse, proactive and dynamic than those in Togo, whereas the strategies employed were more straightforward in Togo than in South Africa. The extent of understanding and use of MSA in both countries consisted of an inter-sectoral action for health, whereby the health department strove to collaborate with other sectors within and outside the government. Consequently, information sharing was identified as the main outcome of the interactions between institutions and interest groups within and across three critical sectors of the state, namely the public (government), the private and the civil society. CONCLUSION: Tobacco control policies in South Africa and Togo were formulated and implemented from an inter-sectoral approach perspective, which relied heavily on information transfer between stakeholders and less on collaborative problem-solving approach. Incorporation of multiple stakeholders allowed both countries to formulate policies to meet FCTC goals for tobacco control and NCD reduction.

Conceptions of Contraceptive Use in Rural KwaZulu-Natal, South Africa: Lessons for Programming.

Community family planning programmes in South Africa arose from the controversial apartheid history of controlling the African population while encouraging the growth of European migrant population. Post-apartheid population policies shifted away from population control to aligning policies to the global agenda that placed emphasis on the link between population and development. The focus on population and development polices in post-apartheid South Africa is on social equality, justice and peace rather than controlling sections of the population. Given the shift, this paper interrogates the conceptions of contraceptive use among rural communities in KwaZulu-Natal. Our primary objective is to understand the dynamics surrounding access to and use of family planning services in peri-urban and rural areas of KwaZulu-Natal. Using focus group data, the findings of the study suggest that different social categories interact with the family planning programmes differently. How teenagers and married women perceive the value of family planning differs. Gender differences regarding the use of condoms are also evident. The paper attempts to grapple with the non-use of condoms despite the knowledge that these prevent pregnancy and provide protection from sexually-transmitted diseases. The contribution of this paper lies in its identification of socio-cultural factors and the political economy underlying the different attitudes towards contraceptive use in rural KwaZulu-Natal.

Perceptions of anal sex in rural South Africa.

As part of the Microbicides Development Programme, we conducted formative research to explore perceptions of anal sex at a site in rural KwaZulu-Natal. We were interested in the practice of anal sex because of its potential role in HIV transmission. Eleven focus group discussions were conducted with men and women from rural areas and in a semi-urban township. Participants were asked about their knowledge of and attitudes towards anal sex, and its practice in the local population. Findings indicate that in discussion anal sex was confused with other non-traditional sexual practices like vaginal sex 'dog-style' and with oral sex. Discussion of anal sex among those who had heard about it linked it to socially marginal groups and asymmetrical power relations.

Gender relations in the context of HIV/AIDS in rural South Africa.

As part of the Microbicides Development Programme, we conducted formative research to explore gender relations at a site in rural KwaZulu-Natal. We were interested in gender relations and in assessing their implications for emerging female initiated and controlled HIV prevention methods in the form of microbicides. Eleven focus group discussions were conducted with men and women in the community. Participants were asked about decision making about sex, family planning and the use of condoms in heterosexual relationships. Findings suggest that gender relations in the context of HIV are complex. The findings suggest that both men and women feel that the final decision about child-bearing and the use of contraceptives and rests with women since they are the ones who bear the burden of child care. This implies that it is feasible for couples to use women-initiated and controlled methods of HIV prevention.
