Background commentary on the Researching the Obesogenic Food Environment (ROFE) project.

OBJECTIVE: The objective of this commentary is to provide an overview of the rationale and objectives of the Researching the Obesogenic Food Environment (ROFE) project that was conducted in Ghana and South Africa. DESIGN: Narration has been used to describe the main objectives, phases as well as the methods used for the conduct of this project. SETTING: The project described in this commentary was conducted in Khayelitsha and Mount Frere in South Africa and Ahodwo and Ejuratia for Ghana. PARTICIPANT: Participants of the study described here include households in South Africa and Ghana, stakeholders and policymakers, and various actors within the food chain in both countries. RESULTS: The ROFE findings provide a good understanding of the extent of the impact of the food environment on consumption, characteristics of value chains of healthy and unhealthy foods, as well as the potential for improved governance and policy that is relevant to the region. The supplement provides the opportunity to share the extensive findings of the ROFE project. Nine papers that describe the process and findings of the three phases of the ROFE project have been presented. Some of the papers focus on phases of the ROFE, while others cut across different phases and explore the linkages between the phases. Briefly descriptions of key findings of some of the papers in the supplement are provided. CONCLUSION: Together, the findings of the ROFE study presented in this supplement have increased understanding of how communities in SA and Ghana interact with their food supplies and have led to identification of specific opportunities to improve food supply policies, in ways that create incentives for the production and consumption of healthy, relative to unhealthy foods.

Scoping review protocol exploring the relationship between food insecurity, mental health and diet intake among adolescents across the globe.

INTRODUCTION: Studies, exploring the effect of food insecurity on physical and mental health, have shown that food insecurity is associated with lower self-reports of physical and mental health. With the COVID-19 pandemic, food insecurity has increased leading to higher risks of poor mental health. Despite evidence of the negative implications of food insecurity on mental health, there is a paucity of research on these variables for adolescents specifically. The current evidence shows there is a gap in adolescent centred research linking mental health and food insecurity globally. Adolescence is a crucial period of development where habits, nutritional inadequacies linked to food insecurity and mental health problems formed due to these inadequacies can be conveyed into adulthood. The aim of this study is to systematically scope the literature exploring the relationship between mental health, food (in)security and/or diet intake of adolescents. METHODS: This review will be guided by Arksey and O'Malley's extended framework. The search strategy was developed by two of the authors and will be used to search literature from January 2012 to December 2022 in PubMed, Academic search complete, PsychARTICLES, Google, ScienceDirect, Scopus and Web of science core collection. Searching published and unpublished literature will be done in the chosen databases. References used in included literature will be reviewed for additional studies/sources. Articles will be assessed for eligibility by two reviewers, and any discrepancies reviewed by a third reviewer. The inclusion and exclusion criteria will be used for screening. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagram will be used to document the selection process. A narrative summary and descriptive analysis will be used to summarise and report the extracted data. ETHICS AND DISSEMINATION: Approval for this study has been granted by the University of the Western Cape Biomedical Research Ethics Committee (BM21/8/3). Strict measures will be followed to ensure methodological rigour.

Comparing estimates of household expenditures between pictorial diaries and surveys in three low- and middle-income countries.

In most low- and middle-income countries (LMICs), household out-of-pocket (OOP) health spending constitutes a major source of healthcare financing. Household surveys are commonly used to monitor OOP health spending, but are prone to recall bias and unable to capture seasonal variation, and may underestimate expenditure-particularly among households with long-term chronic health conditions. Household expenditure diaries have been developed as an alternative to overcome the limitations of surveys, and pictorial diaries have been proposed where literacy levels may render traditional diary approaches inappropriate. This study compares estimates for general household and chronic healthcare expenditure in South Africa, Tanzania and Zimbabwe derived using survey and pictorial diary approaches. We selected a random sub-sample of 900 households across urban and rural communities participating in the Prospective Urban and Rural Epidemiology study. For a range of general and health-specific categories, OOP expenditure estimates use cross-sectional survey data collected via standardised questionnaire, and data from these same households collected via two-week pictorial diaries repeated four times over 2016-2019. In all countries, average monthly per capita expenditure on food, non-food/non-health items, health, and consequently, total household expenditure reported by pictorial diaries was consistently higher than that reported by surveys (each p<0.001). Differences were greatest for health expenditure. The share of total household expenditure allocated to health also differed by method, accounting for 2% in each country when using survey data, and from 8-20% when using diary data. Our findings suggest that the choice of data collection method may have significant implications for estimating OOP health spending and the burden it places on households. Despite several practical challenges to their implementation, pictorial diaries offer a method to assess potential bias in surveys or triangulate data from multiple sources. We offer some practical guidance when considering the use of pictorial diaries for estimating household expenditure.

Lockdown-Associated Hunger May Be Affecting Breastfeeding: Findings from a Large SMS Survey in South Africa.

The impact that the COVID-19 pandemic has had, and will continue to have, on food security and child health is especially concerning. A rapid, Short Message Service (SMS) Maternal and Child Health survey was conducted in South Africa in June 2020 (n = 3140), with a follow-up in July 2020 (n = 2287). This was a national cross-sectional survey conducted among pregnant women and mothers registered with the MomConnect mhealth platform. Logistic regression was conducted to explore the associations between breastfeeding, maternal depressive symptoms, and hunger in the household. High breastfeeding initiation rates and the early introduction of other foods or mixed milk feeding were found. The prevalence of depressive symptoms in this survey sample was 26.95%, but there was no association between breastfeeding behaviour and depressive symptom scores (OR = 0.89; 95% CI: 0.63, 1.27). A positive correlation was found between not breastfeeding and not going to the health clinic. The odds of hungry mothers breastfeeding were significantly lower (OR = 0.66; p = 0.045). This result also holds in a multivariate framework, including covariates such as depressive symptoms, attendance of a PHC facility, and whether the infant was older than 3 months. Support for breastfeeding must include support, such as economic support, for breastfeeding mothers, to enable them to access nutritious diets. Mothers also need reassurance on the quality of their breastmilk and their ability to breastfeed and should be encouraged to continue to attend the health clinic regularly.
