Item Development of evidence-based context appropriate public policy reform models that coherently promote healthy food environments and food consumption patterns in Zambia(University of the Western Cape, 2022) Mukanu, Mulenga Mary; Mchiza, Zandile June-RoseThe double burden of malnutrition is a growing concern globally. In Zambia, it is estimated that of children under five years, 35% are stunted, while 5% are either overweight or obese. In the adult population, 24% are overweight, while 90% do not meet the dietary requirement of consuming five portions of fruit a day. Evidence suggests that unhealthy dietary habits developed by children can contribute to poor health outcomes in adulthood. However, Zambia's nutrition policies are not changing rapidly enough to address the development of new challenges associated with the double burden of malnutrition. Policy reforms should be implemented to re-engineer food environments to support access to healthier food options and make these foods preferable to consumers in critical age groups like adolescence.Item Diet therapy and public health(MDPI, 2022) Mchiza, Zandile June-RoseA major threat to the achievement of the Sustainable Development Goals and Universal Health Coverage continues to be malnutrition [1,2]. The term “malnutrition” encompasses both under- and over-nutrition, both of which coexist and interact, especially in low-tomedium- income countries (LMICs) [3]. As a result, the term DBM has been coined [4] to describe this phenomenon, and this is further described as a “malnutrition syndemic” [5] if malnutrition includes micronutrient deficiencies. Research has implicated DBM and syndemic malnutrition in the development of major metabolic diseases, such as coronary heart disease, hypertension, diabetes, and cancer [6]. According to the WHO [7], at a global level, 7 of the 10 leading causes of death in 2019 were metabolic diseases.Item Exploring factors associated with diabetic retinopathy treatment compliance behaviour in Cape Town, South Africa(MPDI, 2021) Wentzel, Annalie; Mchiza, Zandile June-RoseComplete patient adherence to treatment for diabetic retinopathy (DR) is critical to limit vision loss. There is a dearth of evidence regarding the reasons why South African patients referred for suspected vision-threatening DR stay compliant to or default their treatment. The current study sought to explore factors associated with treatment compliance among patients living with diabetes who have been referred for suspected vision-threatening DR in the Northern/Tygerberg sub-Structure (NTSS) public health care system of Cape Town, South Africa. A qualitative research approach was used where semi-structured in-depth interviews were conducted with 13 adult patients living with DR, and 2 key informants who are primary eye care providers. Thematic data analysis was conducted using taguette.org. Fear of going blind was the most notable patient-related factor associated with compliance. Notable patient-related barriers reported were forgetfulness and a poor state of health. Notable institution-related barriers included suboptimal information received from health care service providers, poor referral management by the organisation delivering retinal screening services, as well as the inaccessibility of the main NTSS hospital via telephone calls. All these factors were confirmed by the key informants of the current study.Item Meals on wheels: Promoting food and nutrition security among older persons in Cape Town, South Africa(MDPI, 2023) Nkurunziza, Magnifique; Mchiza, Zandile June-Rose; Zembe, YangaFood insecurity (FI) prevails in Sub-Saharan Africa. Yet, in South Africa, although many people, including the elderly, are vulnerable to FI, little is known about the experiences of older persons (OPs) with FI and the interventions thereof. In South Africa, Meals on Wheels Community Service (MOWCS) provides readymade home meal deliveries for OPs through 209 branches across the country. Therefore, this study investigated MOWCS’ role in the promotion of food security among the OPs at the Brooklyn branch, Cape Town. The study was grounded within the food security framework and focused on the availability, accessibility, utilization, and stability of food at Brooklyn MOWCS. Using qualitative research methods, 10 semi-structured interviews and one focus group discussion (N = 5) were conducted with Brooklyn MOWCS beneficiaries, in addition to three key personnel interviews conducted with staff. Data were analysed using Open Code 4.03. The findings showed Brooklyn MOWCS as a stable source of affordable and nutritious meals to OPs.Item Mental health and physical activity: A COVID-19 viewpoint(Bentham Open, 2021) Onagbiye, Sunday O.; Mchiza, Zandile June-Rose; Ahanonu, Ezihe L.COVID-19, which has been declared a pandemic by the World Health Organisation, has become a public health emergency across the globe. It is a highly contagious disease, which elicits high levels of fear amongst the world population and is considered a threat to the world economy. As a response to this pandemic, international governments have devised unconventional measures to guard the health of their citizenry. Among these are the “new normal” country lockdown that mandates working from home, home-schooling of children, and physical/social distancing from friends and family. For the majority, this has resulted in momentary job loss and loneliness, and other psychological illnesses. Hence millions are frightened, depressed and panic easily as a result of the tension due to the uncertainty, which interferes with their job performance, livelihoods, international trade and the world economy. If not mitigated, this is likely to cause physical health deterioration, with severe mental illness being the outcome. To reduce mental health illnesses during and after the COVID-19 pandemic, evidence suggests prioritising regular participation in physical activity and exercise across lifespan. It is also important for medical experts who specialise in the care and management of mental health to recognise physical activity and exercise as a medicine that can ameliorate some mental illnesses and their associated risk factors.Item Nurturing children's development through healthy eating and active living: Time for policies to support effective interventions in the context of responsive emotional support and early learning(Health & Social Care in the Community, 2022) Mchiza, Zandile June-Rose; Skouteris, Helen; Green, Rachael; Chung, Alexandra; Bergmeier, HeidiFostering the growth, development, health, and wellbeing of children is a global priority. The early childhood period presents a critical window to influence lifelong trajectories, however urgent multisectoral action is needed to ensure that families are adequately supported to nurture their children's growth and development. With a shared vision to give every child the best start in life, thus helping them reach their full developmental potential, we have formed the International Healthy Eating Active Living Matters (HEALing Matters) Alliance. Together, we form a global network of academics and practitioners working across child health and development, and who are dedicated to improving health equity for children and their families. Our goal is to ensure that all families are free from structural inequality and oppression and are empowered to nurture their children's growth and development through healthy eating and physical activity within the context of responsive emotional support, safety and security, and opportunities for early learning. To date, there have been disparate approaches to promoting these objectives across the health, community service, and education sectors. The crucial importance of our collective work is to bring these priorities for early childhood together through multisectoral interventions, and in so doing tackle head on siloed approaches. In this Policy paper, we draw upon extensive research and call for collective action to promote equity and foster positive developmental trajectories for all children. We call for the delivery of evidence-based programs, policies, and services that are co-designed to meet the needs of all children and families and address structural and systemic inequalities. Moving beyond the “what” is needed to foster the best start to life for all children, we provide recommendations of “how” we can do this. Such collective impact will facilitate intergenerational progression that builds human capital in future generations. © 2022 The Authors.

The purpose of the present study was to determine relationships between obesity, physical activity, sleep patterns and beverage consumption among black South African women in a rural village in the Limpopo province. Methods: A cross-sectional study was conducted among 200 rural-dwelling African women. Data were collected on beverage consumption, sociodemographic information, sleep patterns and anthropometry using self-reported questionnaires. Results: The mean body mass index (BMI) was 28.5±7.3 kg/m2, with 40% being classified as obese (BMI ≥30 kg/m2) and the mean sleep score was 4.68±2.51. Participants with very bad habitual sleeping patterns consumed significantly more sugar-sweetened beverages and alcohol than those with very good sleeping patterns. We also observed that when total coffee with sugar, fruit juice, total sugar-sweetened beverages and weight decreased the number of hours participants slept increased. Conclusions: The study identified significant associations between body weight, sleep duration and sugar-sweetened beverage consumption among rural black South African women. This underscores a need to address unhealthy lifestyle behaviours to lower incidences of non-communicable diseases in rural-dwelling women.Item Policy implementation and recommendations to address the double burden of malnutrition in South Africa: expert assessment using the expanded Healthy Food Environment Policy Index (Food-EPI)(BioMed Central Ltd, 2025) Mchiza, Zandile June-Rose; Holliday, Nicole; Delobelle, PeterBackground: South Africa faces a double burden of malnutrition (DBM), the coexistence and interaction of multiple forms of malnutrition (undernutrition, micronutrient deficiencies, and overweight/obesity) within individuals and households and across the life course. A healthy food environment is necessary to reduce this DBM. The Healthy Food Environment Policy Index (Food-EPI) can be used to evaluate the implementation of public nutrition and food environment policies in comparison with international best practices. The aim of this study was to assess the extent of implementation of healthy food environment policies in South Africa using an expanded DBM Food-EPI framework, benchmark policies against international best practices, develop priority policy recommendations, and compare implementation progress since the 2016 South African Food-EPI assessment. Methods: From October 2023 to March 2024, a panel of 23 national experts from different tiers of government (Department of Health), academia, and civil society was invited to participate in the Food-EPI assessment. Through two workshops and online feedback, experts evaluated the implementation of food environment policies across 60 indicators, compared these policies to international best practices, and proposed and prioritized a list of policy actions based on perceived implementation gaps. Results: Of the 23 invited experts, 13 participated in the benchmarking workshop in which about 70% of indicators were rated at very low to low levels of implementation. Overall, of the 48 original indicators, the mean level of implementation improved from 2016 to 2024. Of the 12 indicators that addressed the DBM, eight were rated at very low to low levels of implementation. The experts (original panel plus four additional participants) then proposed ten priority actions, mainly across the domains of Food Promotion, Food Prices, Funding, and Platforms for Interaction. Conclusions: Application of the expanded Food-EPI in South Africa showed improvements for the original indicators compared with 2016 and highlights the need for additional policy efforts to improve public nutrition policy and address the DBM.Item Social and psychological predictors of body mass index among South Africans 15 years and older: Sanhanes-1(MPDI, 2019) Mchiza, Zandile June-Rose; Parker, Whadi-Ah; Hossin, Muhammad ZakirThis study investigated how psychological distress and the proxies for social position combine to influence the risk of both underweight and overweight in South Africans aged 15 years and older. This was a cross-sectional study that included 2254 men and 4170 women participating in the first South African National Health and Nutrition Examination Survey (SANHANES-1). An analysis exploring the associations of social and mental health characteristics with body mass index (BMI) was conducted using binary and multinomial logistic regressions. Results suggested that, overall, women had a higher risk of overweight/obesity compared to men (age-adjusted odds ratio [AOR] 4.65; 95% confidence intervals [CI] 3.94–5.50). The gender effect on BMI was smaller in non-African participants (AOR 3.02; 95% CI 2.41–3.79; p-value for interaction = 0.004). Being employed and having a higher level of education were associated with higher risks of overweight and obesity and a lower risk of underweight. Being single or without a spouse and poor mental health were found to increase the odds of being underweight, especially in men. To conclude, there are strong social gradients and important gender and ethnic differences in how BMI is distributed in the South African population.
