RESUMEN
Although commercial entities can contribute positively to health and society there is growing evidence that the products and practices of some commercial actors-notably the largest transnational corporations-are responsible for escalating rates of avoidable ill health, planetary damage, and social and health inequity; these problems are increasingly referred to as the commercial determinants of health. The climate emergency, the non-communicable disease epidemic, and that just four industry sectors (ie, tobacco, ultra-processed food, fossil fuel, and alcohol) already account for at least a third of global deaths illustrate the scale and huge economic cost of the problem. This paper, the first in a Series on the commercial determinants of health, explains how the shift towards market fundamentalism and increasingly powerful transnational corporations has created a pathological system in which commercial actors are increasingly enabled to cause harm and externalise the costs of doing so. Consequently, as harms to human and planetary health increase, commercial sector wealth and power increase, whereas the countervailing forces having to meet these costs (notably individuals, governments, and civil society organisations) become correspondingly impoverished and disempowered or captured by commercial interests. This power imbalance leads to policy inertia; although many policy solutions are available, they are not being implemented. Health harms are escalating, leaving health-care systems increasingly unable to cope. Governments can and must act to improve, rather than continue to threaten, the wellbeing of future generations, development, and economic growth.

BACKGROUND: Malnutrition remains a pressing public health concern for mothers and children in South Africa. Despite the government's multisectoral response, unaddressed social needs prevent some mothers getting full benefit from interventions, spanning financial planning, income stability, housing, access to government services, social support, and provision of affordable, nutritious foods. Engaging with mothers and prioritising their concerns is important if we wish to overcome obstacles to women benefiting from government nutrition interventions. This study aimed to identify the programmes that women perceived as a priority in addressing the social needs of mothers of young infants and pregnant women to enhance nutrition in a resource-constrained urban township in South Africa. METHODS: A cross-sectional study employed a quantitative preference elicitation survey, administered to 210 mothers and pregnant women from five primary healthcare facilities in Soweto. The survey tool was developed with the community to identify unmet social needs and potential solutions, which were synthesised with findings from the literature. The survey described 15 programmes, grouped into three delivery levels: clinics, community, and government. Participants were required to rank programme options in two stages. First, they selected their top two programmes within each delivery level. Subsequently, they allocated stickers to indicate the strength of their preference among the top programmes across the levels. Rankings were analysed using descriptive statistics. RESULTS: The highest priority was given to five programmes. Two delivered at the community level: Women's economic empowerment groups and Job search assistance, two at the clinic level: Social needs assessment and referral, and Prescription-based food, and one at the government level: Free quality childcare. The lowest-ranked programmes were two clinic-based programmes, specifically Maternal nutrition groups and Couple antenatal education. CONCLUSION: Women expressed strong views about which programmes should be prioritised to support mothers and pregnant women in addressing their social needs and improving nutrition. Key areas included providing support with job searching and entrepreneurship, accessing childcare and the healthy foods recommended at clinics, as well as finding information on available community and government services. Leveraging multisectoral collaboration, aligned policy objectives, efficient public financing, and strengthened implementation capacity will be pivotal in delivering these programmes.

BACKGROUND: Achieving universal health coverage (UHC) in the context of limited resources will require prioritising the most vulnerable and ensuring health policies and services are responsive to their needs. One way of addressing this is through the engagement of marginalised voices in the priority setting process. Public engagement approaches that enable group level deliberation as well as individual level preference capturing might be valuable in this regard, but there are limited examples of their practical application, and gaps in understanding their outcomes, especially with rural populations. OBJECTIVE: To address this gap, we implemented a modified priority setting tool (Choosing All Together-CHAT) that enables individuals and groups to make trade-offs to demonstrate the type of health services packages that may be acceptable to a rural population. The paper presents the findings from the individual choices as compared to the group choices, as well as the differences among the individual choices using this tool. METHODS: Participants worked in groups and as individuals to allocate stickers representing the available budget to different health topics and interventions using the CHAT tool. The allocations were recorded at each stage of the study. We calculated the median and interquartile range across study participants for the topic totals. To examine differences in individual choices, we performed Wilcoxon rank sum tests. RESULTS: The results show that individual interests were mostly aligned with societal ones, and there were no statistically significant differences between the individual and group choices. However, there were some statistically significant differences between individual priorities based on demographic characteristics like age. DISCUSSION: The study demonstrates that giving individuals greater control and agency in designing health services packages can increase their participation in the priority setting process, align individual and community priorities, and potentially enhance the legitimacy and acceptability of priority setting. Methods that enable group level deliberation and individual level priority setting may be necessary to reconcile plurality. The paper also highlights the importance of capturing the details of public engagement processes and transparently reporting on these details to ensure valuable outcomes. PUBLIC CONTRIBUTION: The facilitator of the CHAT groups was a member from the community and underwent training from the research team. The fieldworkers were also from the community and were trained and paid to capture the data. The participants were all members of the rural community- the study represents their priorities.
RESUMEN
BACKGROUND: In South Africa, overweight and obesity affect 17% of children aged 15-18. School food environments play a vital role in children's health, influencing dietary behaviours and resulting in high obesity rates. Interventions targeting schools can contribute to obesity prevention if evidence-based and context-specific. Evidence suggests that current government strategies are inadequate to ensure healthy school food environments. The aim of this study was to identify priority interventions to improve school food environments in urban South Africa using the Behaviour Change Wheel model. METHODS: A three-phased iterative study design was implemented. First, we identified contextual drivers of unhealthy school food environments through a secondary framework analysis of 26 interviews with primary school staff. Transcripts were deductively coded in MAXQDA software using the Behaviour Change Wheel and the Theoretical Domains Framework. Second, to identify evidence-based interventions, we utilised the NOURISHING framework and matched interventions to identified drivers. Third, interventions were prioritised using a Delphi survey administered to stakeholders (n = 38). Consensus for priority interventions was defined as an intervention identified as being 'somewhat' or 'very' important and feasible with a high level of agreement (quartile deviation ≤ 0.5). RESULTS: We identified 31 unique contextual drivers that school staff perceived to limit or facilitate a healthy school food environment. Intervention mapping yielded 21 interventions to improve school food environments; seven were considered important and feasible. Of these, the top priority interventions were to: 1) "regulate what kinds of foods can be sold at schools", 2) "train school staff through workshops and discussions to improve school food environment", and affix 3) "compulsory, child-friendly warning labels on unhealthy foods". CONCLUSION: Prioritising evidence-based, feasible and important interventions underpinned by behaviour change theories is an important step towards enhanced policy making and resource allocation to tackle South Africa's childhood obesity epidemic effectively.

BACKGROUND: Voices of under-resourced communities are recognised as important yet are often unheard in decisions about healthcare resource allocation. Deliberative public engagement can serve as an effective mechanism for involving communities in establishing nutrition priorities. This study sought to identify the priorities of community members of a South African township, Soweto, and describe the underlying values driving their prioritisation process, to improve nutrition in the first 1000 days of life. METHODS: We engaged 54 community members (28 men and 26 women aged > 18 years) from Soweto. We conducted seven group discussions to determine how to allocate limited resources for prioritising nutrition interventions. We used a modified public engagement tool: CHAT (Choosing All Together) which presented 14 nutrition intervention options and their respective costs. Participants deliberated and collectively determined their nutritional priorities. Choices were captured quantitatively, while group discussions were audio-recorded. A thematic analysis was undertaken to identify the reasons and values associated with the selected priorities. RESULTS: All groups demonstrated a preference to allocate scarce resources towards three priority interventions-school breakfast provisioning, six-months paid maternity leave, and improved food safety. All but one group selected community gardens and clubs, and five groups prioritised decreasing the price of healthy food and receiving job search assistance. Participants' allocative decisions were guided by several values implicit in their choices, such as fairness and equity, efficiency, social justice, financial resilience, relational solidarity, and human development, with a strong focus on children. Priority interventions were deemed critical to supporting children's optimal development and well-being, interrupting the intergenerational cycle of poverty and poor human development in the community. CONCLUSION: Our study demonstrates how public engagement can facilitate the incorporation of community values and programmatic preferences into nutrition priority setting, enabling a responsive approach to local community needs, especially in resource constrained contexts. Findings could guide policy makers to facilitate more appropriate decisions and to improve nutrition in the first 1000 days of life.

BACKGROUND: In South Africa, an estimated 85% of the population relies on the public sector for oral health services. With poor infrastructure and inadequate personnel, over 80% of children with dental caries remain untreated. To reduce this burden of disease, one key goal is to promote good oral health and address oral diseases through prevention, screening, and treatment among children. While all policies have been proven to be effective in the control and prevention of dental caries, it is unclear which of those strategies provide value for money. This study evaluated five caries preventative strategies in terms of the cost and benefits among South African school children. METHODS: The study uses a hypothetical South African population of school aged learners aged 5-15. The context and insights of the strategies utilized at the schools were informed by data from both grey and published literature. Using Markov modeling techniques, we conducted a cost-effectiveness analysis of Acidulated Phosphate Fluoride (APF) application, atraumatic restorative treatment (ART), sugar-reduction and fissure sealants. Markov model was used to depict the movement of a hypothetical patient cohort between different health states over time. We assessed both health outcomes and costs of various interventions. The health outcome metric was measured as the number of Decayed, Missing, Filled Tooth (DMFT). The net monetary benefit was then used to determine which intervention was most cost-effective. RESULTS: The results showed that school-based caries prevention strategies are cost-effective compared to the status quo of doing nothing. The average cost per learner over the 10-year period ranged from ZAR4380 to approx. ZAR7300 for the interventions considered. The total costs (including screening) associated with the interventions and health outcome (DMFT averted) were: sugar reduction (ZAR91,380, DFMT: 63,762), APF-Gel (ZAR54 million, DMFT: 42,010), tooth brushing (ZAR72.8 million, DMFT: 74,018), fissure sealant (ZAR44.63 million, DMFT: 100,024), and ART (ZAR45 million, DMFT: 144,035). The net monetary benefits achieved for APF-Gel, sugar reduction, tooth brushing, fissure sealant and ART programs were ZAR1.56, ZAR2.45, ZAR2.78, ZAR3.81, and ZAR5.55 billion, respectively. CONCLUSION: Based on the net monetary benefit, ART, fissure sealant and sugar-reduction appear to be the most cost-effective strategies for preventing caries in South Africa. In a resource-scarce setting such as South Africa, where there is no fluoridation of drinking water, this analysis can inform decisions about service packages for oral health.

OBJECTIVES: While ethics has been identified as a core component of health technology assessment (HTA), there are few examples of practical, systematic inclusion of ethics analysis in HTA. Some attribute the scarcity of ethics analysis in HTA to debates about appropriate methodology and the need for ethics frameworks that are relevant to local social values. The "South African Values and Ethics for Universal Health Coverage" (SAVE-UHC) project models an approach that countries can use to develop HTA ethics frameworks that are specific to their national contexts. METHODS: The SAVE-UHC approach consisted of two phases. In Phase I, the research team convened and facilitated a national multistakeholder working group to develop a provisional ethics framework through a collaborative, engagement-driven process. In Phase II, the research team refined the model framework by piloting it through three simulated HTA appraisal committee meetings. Each simulated committee reviewed two case studies of sample health interventions: opioid substitution therapy and either a novel contraceptive implant or seasonal influenza immunization for children under five. RESULTS: The methodology was fit-for-purpose, resulting in a context-specified ethics framework and producing relevant findings to inform application of the framework for the given HTA context. CONCLUSIONS: The SAVE-UHC approach provides a model for developing, piloting, and refining an ethics framework for health priority-setting that is responsive to national social values. This approach also helps identify key facilitators and challenges for integrating ethics analysis into HTA processes.

Primary healthcare systems are central to achieving universal healthcare coverage. However, in many low- and middle-income country settings, primary care quality is challenged by inadequate facility infrastructure and equipment, limited human resources, and poor provider process. We study the effects of a recent large-scale quality improvement policy in South Africa, the Ideal Clinics Realization and Maintenance Program (ICRMP). The ICRMP introduced a set of standards for facilities and a quality improvement process involving manuals, district-based support, and external assessment. Exploiting differential prioritization of facilities for the ICRMP's quality improvement process, we apply differences-in-differences methods to identify the effects of the program's efforts on standards scores and primary care quality indicators over the first 12 months of implementation. We find large and statistically significant increases in standards scores, but mixed effects on care outcomes-a small magnitude improvement in early antenatal care usage, null effects on childhood immunization and cervical cancer screening, and small negative effect of human immunodeficiency virus (HIV) care. While the ICRMP process has led to significant improvements in facilities' satisfaction of the program's standards, we were unable to detect meaningful change in care quality indicators.

OBJECTIVE: To provide insight into the context and public health implications of the South African sugar-sweetened beverage (SSB) tax (Health Promotion Levy; HPL) by describing SSB and added sugar intakes, as well as BMI, 1 year prior to, at the time of and 1 year after implementation of the HPL. DESIGN: Longitudinal dietary intake was assessed using a quantitative food frequency questionnaire (QFFQ) and BMI was measured via anthropometry. SETTING: Soweto, Johannesburg, South Africa. PARTICIPANTS: Adolescents, young adults and middle-aged adults (n 617). RESULTS: At baseline, median SSB intakes were 36 ml/d, 214 ml/d and 750 ml/d for those in low, medium and high consumption tertiles, respectively. SSB intake decreased by two times/week in medium consumers and seven times/week in high consumers between baseline and 12 months, equivalent to 107 ml/d and 536 ml/d reductions, respectively. These reduced levels were maintained in the following year (i.e. to 24 months). There was an overall decrease in the amount of energy consumed as added sugar in the low (-48 kJ/d), medium (-153 kJ/d) and high (-106 kJ/d) SSB consumption groups between baseline and 24 months; however, the percentage of total energy consumed as added sugar remained relatively consistent (between 10 and 11 %). There were small overall increases in BMI across low (0·6 kg/m2), medium (0·9 kg/m2) and high (1·0 kg/m2) SSB tertiles between baseline and 24 months. CONCLUSIONS: These findings suggest reductions in SSB and added sugar consumption contemporaneous to the introduction of the HPL - particularly for those with higher baseline intakes.

OBJECTIVE: To obtain a community perspective on key nutrition-specific problems and solutions for mothers and children. DESIGN: A qualitative study comprising nine focus group discussions (FGD) following a semi-structured interview guide. SETTING: The township of Soweto in South Africa with a rising prevalence of double burden of malnutrition. PARTICIPANTS: Men and women aged ≥18 years (n 66). Three FGD held with men, six with women. RESULTS: Despite participants perceived healthy diet to be important, they felt their ability to maintain a healthy diet was limited. Inexpensive, unhealthy food was easier to access in Soweto than healthier alternatives. Factors such as land use, hygiene and low income played a fundamental role in shaping access to foods and decisions about what to eat. Participants suggested four broad areas for change: health sector, social protection, the food system and food environment. Their solutions ranged from improved nutrition education for women at clinic visits, communal vegetable gardens and government provision of food parcels to regulatory measures to improve the healthiness of their food environment. CONCLUSIONS: South Africa's current nutrition policy environment does not adequately address community-level needs that are often linked to structural factors beyond the health sector. Our findings suggest that to successfully address the double burden of malnutrition among women and children, a multifaceted approach is needed combining action on the ground with coherent policies that address upstream factors, including poverty. Further, there is a need for public engagement and integration of community perspectives and priorities in developing and implementing double-duty actions to improve nutrition.

OBJECTIVE: To explore community perceptions on maternal and child nutrition issues in Sub-Saharan Africa. DESIGN: Thirty focus groups with men and women from three communities facilitated by local researchers. SETTING: One urban (Soweto, South Africa) and two rural settings (Navrongo, Ghana and Nanoro, Burkina Faso) at different stages of economic transition. PARTICIPANTS: Two hundred thirty-seven men and women aged 18-55 years, mostly subsistence farmers in Navrongo and Nanoro and low income in Soweto. RESULTS: Differences in community concerns about maternal and child health and nutrition reflected the transitional stage of the country. Community priorities revolved around poor nutrition and hunger caused by poverty, lack of economic opportunity and traditional gender roles. Men and women felt they had limited control over food and other resources. Women wanted men to take more responsibility for domestic chores, including food provision, while men wanted more involvement in their families but felt unable to provide for them. Solutions suggested focusing on ways of increasing control over economic production, family life and domestic food supplies. Rural communities sought agricultural support, while the urban community wanted regulation of the food environment. CONCLUSIONS: To be acceptable and effective, interventions to improve maternal and child nutrition need to take account of communities' perceptions of their needs and address wider determinants of nutritional status and differences in access to food reflecting the stage of the country's economic transition. Findings suggest that education and knowledge are necessary but not sufficient to support improvements in women's and children's nutritional status.

BACKGROUND: Evidence-informed clinical practice guidelines (CPGs) are useful tools to inform transparent healthcare decision-making. Consideration of health economic evidence (HEE) during CPG development in a structured manner remains a challenge globally and locally. This study explored the views, current practice, training needs and challenges faced by CPG developers in the production and use of HEE for CPGs in South Africa. METHODS: This mixed-methods study comprised an online survey and a focus group discussion. The survey was piloted and subsequently sent to CPG role players - evidence reviewers, CPG panellists, academics involved with training in relevant disciplines like health economics and public health, implementers and funders. The focus group participants hold strategic roles in CPG development and health economic activities nationally. The survey evaluated mean values, measures of variability, and percentages for Likert scales, while narrative components were thematically analysed. Focus group data were manually coded, thematically analysed and verified. RESULTS: The survey (n = 55 respondents to 245 surveys distributed) and one focus group (n = 5 participants from 10 people invited) occurred between October 2018 and February 2019. We found the most consistent reason why HEE should inform CPG decisions was 'making more efficient use of limited financial resources'. This was explained by numerous context and methodological barriers. Focus groups participants noted that consideration of complex HEE are not achievable without bolstering skills in applying evidence-based medicine principles. Further concerns include lack of clarity of standard methods; inequitable and opaque topic selection across private and public sectors; inadequate skills of CPG panel members to use HEE; and the ability of health economists to communicate results in accessible ways. Overall, in the absence of clarity about process and methods, politics and interests may drive CPG decisions about which interventions to implement. CONCLUSIONS: HEE should ideally be considered in CPG decisions in South Africa. However, this will remain hampered until the CPG community agree on methods and processes for using HEE in CPGs. Focused investment by national government to address the challenges identified by the study is imperative for a better return on investment as National Health Insurance moves forward.

Industrialization and urbanization processes have challenged deeply held traditional gender norms and facilitated the emergence of modern ideologies in South Africa. This paper seeks to explore the gendered roles of family members on maternal and child nutrition and investigate indications of perceived change in related practices. A qualitative secondary analysis was conducted of data from nine focus group discussions (FGDs) held with men (n = 3) and women (n = 6) aged ≥18. Data from the FGD were coded and thematic analysis conducted. We found that elderly women seem to have a central advisory role with respect to maternal and child nutrition and that men and elderly women upheld patriarchal gender divisions of labour, which entrust mothers with the primarily responsibility for young children's nutrition. Young mothers relied on elderly women for provision of childcare and nutritious foods for children; however, they demonstrated some resistance to traditionally feminized forms of food preparation. We found that men's involvement in children's nutrition was limited, though they expressed a preference to be more involved in maternal and child nutrition and care practices. A gender transformative approach to policy development, which includes elderly women and men, has the potential to promote more gender-equitable nutrition practices, increase young women's self-efficacy and support them to overcome barriers that could be limiting their decision making power in achieving optimal nutrition for themselves and their children.

BACKGROUND: In 2016, the South African government became the first in the African region to announce the introduction of an SSB tax based on sugar content as a public health measure to reduce obesity. This tax was introduced against the backdrop of South Africa having a large sugar production and SSB manufacturing industry, as well as very high unemployment rates. The introduction of fiscal measures, such as a SSB tax, has been met with well-coordinated and funded opposition in other countries. METHODS: The aim of this study is to describe and analyse the arguments and strategies utilised by industry during policymaking processes to oppose regulatory actions in LMIC. This study analyses arguments and strategies used by the beverage and related industries during the public consultation phase of the process to adopt the South African SSB tax. RESULTS: Industry opposition to the SSB tax was comprehensive and employed several tactics. First, industry underscored its economic importance and the potential job losses and other economic harms that may arise from the tax. This argument was well-received by policymakers, and similar to industry tactics employed in other middle income countries like Mexico. Second, industry discussed self-regulation and voluntary measures as a form of policy substitution, which mirrors industry responses in the US, the Caribbean and Latin America. Third, industry misused or disputed evidence to undermine the perceived efficacy of the tax. Finally, considerations for small business and their ability to compete with multi-national corporations were a unique feature of industry response. CONCLUSIONS: Industry opposition followed both general trends, and also introduced nuanced and context-specific arguments. The industry response experienced in South Africa can be instructive for other countries contemplating the introduction of similar measures.

BACKGROUND: Non-communicable diseases (NCDs) are the leading cause of death globally. While upstream approaches to tackle NCD risk factors of poor quality diets and physical inactivity have been trialled in high income countries (HICs), there is little evidence from low and middle-income countries (LMICs) that bear a disproportionate NCD burden. Sub-Saharan Africa and the Caribbean are therefore the focus regions for a novel global health partnership to address upstream determinants of NCDs. PARTNERSHIP: The Global Diet and Activity research Network (GDAR Network) was formed in July 2017 with funding from the UK National Institute for Health Research (NIHR) Global Health Research Units and Groups Programme. We describe the GDAR Network as a case example and a potential model for research generation and capacity strengthening for others committed to addressing the upstream determinants of NCDs in LMICs. We highlight the dual equity targets of research generation and capacity strengthening in the description of the four work packages. The work packages focus on learning from the past through identifying evidence and policy gaps and priorities, understanding the present through adolescent lived experiences of healthy eating and physical activity, and co-designing future interventions with non-academic stakeholders. CONCLUSION: We present five lessons learned to date from the GDAR Network activities that can benefit other global health research partnerships. We close with a summary of the GDAR Network contribution to cultivating sustainable capacity strengthening and cutting-edge policy-relevant research as a beacon to exemplify the need for such collaborative groups.

OBJECTIVE: In the past decade, South Africa's obesity epidemic has increased in both children and adults, and being overweight is becoming the norm. Several contributing factors lead to the normalisation of obesity. One of these is the culturally entrenched likeness of larger body sizes or shapes within a milieu of easily accessible unhealthy food and beverages. This qualitative study advances knowledge about the influence of socio-cultural norms and obesogenic environments on weight under estimation and 'obesity normalisation' amongst black South Africans living in an urban setting. DESIGN: A theory-based qualitative study used focus group discussions (FGDs) with a semi-structured interview guide. FGDs were transcribed verbatim and analysed thematically using a constant comparison method. SETTING: Soweto, Johannesburg, South Africa, is a setting which has undergone rapid urbanisation and nutrition transition with ubiquitous availability of processed and fast-foods. PARTICIPANTS: Adults older than 18 years living in Soweto (n 57). RESULTS: There is a wide misperception about obesity amongst black Africans living in an urban setting in Soweto. Participants who admitted to being fat or overweight did not view themselves as such. This could be attributed to unchanging socio-cultural factors that reinforce the acceptability of bigger bodies and living in obesogenic environment. CONCLUSIONS: Without addressing socio-cultural norms that attribute bigger bodies to beauty and wealth, motivating individuals to address weight gain will prove difficult especially for populations living in obesogenic environments. A multi-faceted strategy is required to address obesity in urban South African settings.

OBJECTIVE: A tax on sugar-sweetened beverages (SSB) was introduced in South Africa in April 2018. Our objective was to document perceptions and attitudes among urban South Africans living in Soweto on factors that contribute to their SSB intake and on South Africa's use of a tax to reduce SSB consumption. DESIGN: We conducted six focus group discussions using a semi-structured guide. SETTING: The study was conducted in Soweto, Johannesburg, South Africa, 3 months before South Africa's SSB tax was implemented. PARTICIPANTS: Adults aged 18 years or above living in Soweto (n 57). RESULTS: Participants reported frequent SSB consumption and attributed this to habit, addiction, advertising and wide accessibility of SSB. Most of the participants were not aware of the proposed SSB tax; when made aware of the tax, their responses included both beliefs that it would and would not result in reduced SSB intake. However, participants indicated cynicism with regard to the government's stated motivation in introducing the tax for health rather than revenue reasons. CONCLUSIONS: While an SSB tax is a policy tool that could be used with other strategies to reduce people's high level of SSB consumption in Soweto, our findings suggest a need to complement the SSB tax with a multipronged behaviour change strategy. This strategy could include both environmental and individual levers to reduce SSB consumption and its associated risks.

OBJECTIVES: Health technology assessment (HTA) is a cost-effective resource allocation tool in healthcare decision-making processes; however, its use is limited in low-income settings where countries fall short on both absorptive and technical capacity. This paper describes the journey of the introduction of HTA into decision-making processes through a case study revising the National Essential Medicines List (NEMLIT) in Tanzania. It draws lessons on establishing and strengthening transparent priority-setting processes, particularly in sub-Saharan Africa. METHODS: The concept of HTA was introduced in Tanzania through revision of the NEMLIT by identifying a process for using HTA criteria and evidence-informed decision making. Training was given on using economic evidence for decision making, which was then put into practice for medicine selection for the NEMLIT. During the revision process, capacity-building workshops were held with reinforcing messages on HTA. RESULTS: Between the period 2014 and 2018, HTA was introduced in Tanzania with a formal HTA committee being established and inaugurated followed by the successful completion and adoption of HTA into the NEMLIT revision process by the end of 2017. Consequently, the country is in the process of institutionalizing HTA for decision making and priority setting. CONCLUSION: While the introduction of HTA process is country-specific, key lessons emerge that can provide an example to stakeholders in other low- and middle-income countries (LMICs) wishing to introduce priority-setting processes into health decision making.

The consumption of sugary beverages (SBs) has increasingly grown in many countries and is a significant contributor to the rise in obesity and non-communicable diseases (NCDs). In response, public health officials in multiple countries have pushed for implementing a tax on SBs in order to reduce their consumption. Today, many individuals, especially those of lower socioeconomic status, live in environments in which unhealthy foods and drinks are more accessible than healthier ones. The beverage industry has greatly contributed to the formation of these "obesogenic" environments through their extensive advertising activities and effective marketing strategies. With rising public awareness of sugar's link to obesity, the industry has heavily invested in campaigns that seek to shift the blame away from their products and has aggressively opposed legislative efforts to pass an SB tax. This perspective will focus on explaining the rationale and necessity of an SB tax by highlighting the tactics the beverage industry has employed that have contributed to the formation and maintenance of the present unhealthy food environment.

South Africa faces a severe and growing obesity epidemic. Obesity and its co-morbidities raise public and private expenditures on healthcare. Sugary beverages are heavily consumed in South Africa and are linked to the onset of overweight and obesity. Excise taxation of sugary beverages has been proposed and adopted in other settings as a means to reduce harms from their consumption. A tax on the sugar content of non-alcoholic beverages has been proposed for implementation in South Africa, however, the public health effects and revenue raising potential of this measure hinges on estimates of the targeted beverages own- and cross-price elasticities. This study applies demand system methods by combining expenditure survey data and sub-national price data to provide the first estimates of price and expenditure elasticities for categories of soft drinks that would be subject to South Africa's proposed sugary beverage tax. The results suggest that demand for these products is sufficiently price-elastic such that a significant reduction in consumption may result from a tax.
