Understanding Structure and Agency as Commercial Determinants of Health Comment on "How Neoliberalism Is Shaping the Supply of Unhealthy Commodities and What This Means for NCD Prevention"

Assessing the determinants of unhealthy dietary habits among a sample of survey participants in Jamaica

Objective.

To identify and assess the determinants of unhealthy dietary habits among a sample of survey participants in Jamaica.

Methods.

Because of resource constraints, this cross-sectional assessment is based on a three-stage non-probability sample of 374 survey respondents in Jamaica aged ≥18 years. Firstly, three administrative areas (parishes) were randomly selected. Secondly, the main commercial areas within the selected parishes were identified, from which a non-probability sample of establishments was drawn. A broad selection of establishments covering public, private, and nongovernmental organizations was chosen. This array of establishments was selected to capture a sample of respondents that was as representative as possible. Patrons and employees in the selected establishments were asked to complete a questionnaire.

Results.

Respondents’ self-assessment of their general consumption revealed that 48.4% were unhealthy eaters. Among these, the top reasons for generally unhealthy dietary choices were greater accessibility of unhealthy foods (63.5%) and limited time to prepare healthy meals (61.3%). Additionally, 52.5% indicated “unhealthy foods cost less,” and 47.0% identified affordability as the main factor in the food choice equation. Findings revealed that the determinants of eating unhealthily tended to vary across income, age, and gender. Female, younger, and lower-income respondents have a higher likelihood of being impacted by the factors.

Conclusions.

The largest proportions of the sample identified limited time to prepare healthy meals and the ease of access to unhealthy foods as the foremost determinants of unhealthy eating habits. These barriers to healthy eating are more likely to impact survey participants in the 18–34 age group.

Health Taxes on Tobacco, Alcohol, Food and Drinks in Low- and Middle-Income Countries: A Scoping Review of Policy Content, Actors, Process and Context

BACKGROUND

Taxation of tobacco, food, alcohol and other beverages has gained renewed attention in responding to non-communicable diseases (NCDs). While largely built on evidence from high-income countries (HICs), the projected economic and health benefits of these measures have increased calls for their use in price-sensitive low- and middle-income countries (LMICs). However, uptake has been sporadic and there remains little research on why and how LMICs utilise fiscal measures in response to NCDs.

METHODS

This scoping review analyses factors influencing the design and implementation of health-related fiscal measures in LMICs. Utilising Arksey and O'Malley's scoping review methodology and Walt and Gilson's policy triangle, we considered the contextual, procedural, content and stakeholder-related factors that influenced measures.

RESULTS

We identified 75 papers focussing on health-related fiscal measures, with 47 (63%) focused on tobacco, 5 on alcohol, 6 on soft drink and 4 studies on food-related fiscal regulation. Thirteen papers analysed multiple measures and most papers (n = 66, 88%) were less than a decade old. Key factors enabling the design and implementation of measures included localised health and economic evidence, policy championing, inter-ministerial support, and global or regional momentum. Impeding factors encompassed negative framing and retaliation by industry, vested interests and governmental policy disjuncture. Aligning with theoretic insights from the policy triangle, findings consistently demonstrated that the interplay between factors - rather than the presence or absence of particular factors - has the most profound impact on policy implementation.

CONCLUSION

Given the growing urgency to address NCDs in LMICs, this review highlights the need for recognition and rigorous exploration of political economy factors influencing the design and implementation of fiscal measures. Broader LMIC-specific empirical research is needed to overcome an implication noted in much of the literature: that mechanisms used to enact tobacco taxation are universally applicable to measures targeting foods, alcohol and other beverages.

Measuring the Commercial Determinants of Health and Disease: A Proposed Framework

The commercial determinants of health (CDoH) describe the adverse health effects associated with for-profit actors and their actions. Despite efforts to advance the definition, conceptualization, and empirical analyses of CDoH, the term's practical application to mitigate these effects requires the capacity to measure the influences of specific components of CDoH and the cumulative impacts of CDoH on the health and well-being of specific populations. Building on the Global Burden of Disease Study, we begin by conceptualizing CDoH as risk factor exposures that span agency and structural influences. We identify 6 components of these influences and propose an initial set of indicators and datasets to rank exposures as high, medium, or low. These are combined into a commercial determinants of health index (CDoHi) and illustrated by 3 countries. Although now a proof of concept, comparative analysis of CDoH exposures by population, over time and space, and their associated health outcomes will become possible with further development of indicators and datasets. Expansion of the CDoHi and application to varied populations groups will enable finer targeting of interventions to reduce health harms. The measurement of improvements to health and wellness from such interventions will, in turn, inform overall efforts to address the CDoH.

Climate change and socioeconomic determinants are structural constraints to agency in diet-related non-communicable disease prevention in Vanuatu: a qualitative study

Background

Pacific Island countries, many of which are low- and middle-income countries, have some of the highest rates of diet-related non-communicable diseases (DR-NCDs) globally. These countries also face some of the earliest and most significant impacts of climate change. Several pathways between climate change and DR-NCDs have been described in the literature; however, the scope is broad and lacks context specificity. This paper uses a case study of one Pacific Island country, Vanuatu, to investigate links between climate change and DR-NCDs.

Methods

An ethnographic qualitative research approach was used to share the lived experiences of community participants and to explore and contrast these with the perspectives of key informants at the national level. Data collection comprised thirty-two semi-structured interviews and community fieldwork in two villages using a mix of methods, including group workshops, informal conversations, and observations. Reflexive thematic analysis was conducted on both data sets.

Results

This study found that DR-NCDs are a prominent health concern for ni-Vanuatu people and that structural determinants, including climate change, are the main driving forces for increased DR-NCD risk in the country. However, there was a lack of understanding of the links between climate change and DR-NCDs both at the community and national levels. Structural factors, such as social determinants and climate change, constrained individual and community agency in making optimal food and health choices and promoted the nutrition transition in Vanuatu. Despite the critical role of social determinants and climate change in driving DR-NCD risk, the responsibility for prevention and treatment was considered to rest mainly with the individual. A systems approach is advocated to grasp the complexity and interrelatedness of the causes of DR-NCD risk.

Conclusions

The interaction of structural determinants creates food and health environments that amplify the risk, burden, and consequences of DR-NCDs. It is recommended that the DR-NCD narrative in Vanuatu be re-framed with an emphasis on the range of structural determinants of DR-NCD risk. This will serve to enhance individual and collective agency to not only make healthy food and other behavioural choices but also to exercise agency to transform the structures in a culturally appropriate way.
