An Emergent Framework of the Market Food Environment in Low- and Middle-Income Countries.

ABSTRACT:

Background

Food systems are increasingly recognized as critical for advancing nutrition, and the food environment is viewed as the nexus between those systems and dietary consumption. Developing a measurement framework of the market food environment is a research priority, particularly for low- and middle-income countries (LMICs), which face rapid shifts in markets, dietary patterns, and nutrition outcomes.

Objectives

In this study, we sought to assess current conceptions and measures of the market food environment that could be adapted for use in LMICs.

Methods

We conducted a narrative review of the literature to identify measures of the market food environment in recent use. First, we identified and reviewed frameworks of the food environment for LMICs with a specific focus on the market food environment. Second, we compiled 141 unique measures of the market food environment from 20 articles into a list that was pile-sorted by 5 nutrition experts into domains. We then categorized the measures based on percentage agreement across all sorts. Finally, we compared measured and conceptual domains of the market food environment to identify measurement gaps and needed adaptations.

Results

Conceptual frameworks provide differing definitions of the market food environment but conform in their definitions of food availability, price, marketing, and product characteristics. Greater clarity is needed in defining relevant vendor and product characteristics. Eight measured domains of the market food environment emerged from the literature review, with significant overlap among conceptual domains. Measurement gaps exist for food quality, safety, packaging, desirability, and convenience. Personal characteristics also emerged as measured domains, although these are not part of the food environment per se.

Conclusions

These results are a step toward elucidating how, why, and where we measure the market food environment in LMICs. Future research should focus on prioritizing the most meaningful methods and metrics and on developing new measures where gaps exist.

Project description:BackgroundConducting health impact assessments (HIAs) is a growing practice in various organizations and countries, yet scholarly interest in HIAs has primarily focused on the synergies between exposure and health outcomes. This limits our understanding of what factors influence HIAs and the uptake of their outcomes. This paper presents a framework for conducting participatory quantitative HIA (PQHIA) in low- and middle-income countries (LMICs), including integrating the outcomes back into society after an HIA is conducted. The study responds to the question: what are the different components of a participatory quantitative model that can influence HIA implementation in LMICs?MethodsTo build the framework, we used a case study from a PQHIA fieldwork model developed in Port Louis (Mauritius). To explore thinking on the participatory components of the framework, we extract and analyze data from ethnographic material including fieldnotes, interviews, focus group discussions and feedback exercises with 14 stakeholders from the same case study. We confirm the validity of the ethnographic data using five quality criteria: credibility, transferability, dependability, confirmability, and authenticity. We build the PQHIA framework connecting the main HIA steps with factors influencing HIAs.ResultsThe final framework depicts the five standard HIA stages and summarizes participatory activities and outcomes. It also reflects key factors influencing PQHIA practice and uptake of HIA outcomes: costs for participation, HIA knowledge and interest of stakeholders, social responsibility of policymakers, existing policies, data availability, citizen participation, multi-level stakeholder engagement and multisectoral coordination. The framework suggests that factors necessary to complete a participatory HIA are the same needed to re-integrate HIA results back into the society. There are three different areas that can act as facilitators to PQHIAs: good governance, evidence-based policy making, and access to resources.ConclusionsThe framework has several implications for research and practice. It underlines the importance of applying participatory approaches critically while providing a blueprint for methods to engage local stakeholders. Participatory approaches in quantitative HIAs are complex and demand a nuanced understanding of the context. Therefore, the political and cultural contexts in which HIA is conducted will define how the framework is applied. Finally, the framework underlines that participation in HIA does not need to be expensive or time consuming for the assessor or the participant. Yet, participatory quantitative models need to be contextually developed and integrated if they are to provide health benefits and be beneficial for the participants. This integration can be facilitated by investing in opportunities that fuel good governance and evidence-based policy making.

Project description:BackgroundNigeria is a significant tobacco market and influential country in Africa. Nigeria ratified the WHO Framework Convention on Tobacco Control (FCTC) in 2005. We reviewed Nigeria's tobacco control legislation since 2000 and compliance of the National Tobacco Control Act (NTCA) 2015 with the FCTC.MethodsWe reviewed the National Tobacco Control Bills 2011 (proposed by legislature) and 2014 (proposed by Executive), the NTCA 2015, and media stories on tobacco control from 2008 to 2017.ResultsThe NTCA, despite being more comprehensive than Nigeria's first Tobacco Smoking (Control) law of 1990, maintained provisions promoted by the tobacco industry, for example: allowing designated smoking areas in hospitality venues, higher educational institutions, and transportation venues; a loophole in the advertising restrictions allowing communications with consenting adults; and having the Manufacturers Association of Nigeria (MAN) (which includes tobacco companies) on the National Tobacco Control Committee charged with working with the Ministry of Health to implement the law. The industry is also directly involved with the Standards Organisation of Nigeria (SON) in preparing regulations on cigarette constituents and emissions. In an unprecedented step globally, the law requires that implementing regulations be approved by the National Assembly, giving the industry another opportunity to weaken this law further by lobbying the legislators to favor the industry. As of January 2018, the law was still not being enforced.ConclusionThe NTCA can be strengthened through implementation guidelines still being developed. The industry should be prevented from interfering with through MAN and SON, as required by FCTC Article 5.3.ImplicationsThe tobacco industry works to block Framework Convention on Tobacco Control implementation even after a country ratifies the treaty. The Nigerian case illustrates that it is essential for health authorities to remain vigilant and ensure that the tobacco industry does not play a decision-making role in the process of tobacco legislation and regulation either directly or indirectly. The unprecedented step of requiring approval of implementing regulations for the Nigerian law should not be allowed to become a precedent in other countries.
