Ethical aspects of obesity prevention

Perspectives of agriculture, nutrition and health researchers regarding research governance in Malawi. Using a leadership, ethics, governance and systems framework

BACKGROUND

Research ethics is intertwined with and depends on building robust and responsive research governance systems alongside researchers. Globally there has been substantial investment in agriculture, nutrition, and health (ANH) research motivated by the need to improve health outcomes, such as micronutrient deficiencies in Sub-Saharan Africa. Although there has been a notable focus on ethical issues inherent in ANH studies, there has been scanty research examining researchers' attitudes related to ANH research. This study was conducted to explore the perspectives of researchers who conducted an agronomic biofortification study in Malawi.

METHODOLOGY

In-depth interviews were conducted with a purposive sample of ten ANH researchers. Interviews were conducted online via Zoom, audio-recorded, transcribed verbatim, and thematically analysed using the Leadership, Ethics, Governance and Systems Framework.

RESULTS

Four core aspects emerged: Leadership: The relevance of building ethics leadership and ethical competence among researchers.

ETHICS

There is a need to develop a framework that operationalises core ethical values that can guide the implementation of ANH research. Governance: Research guidelines were perceived to be too generic to guide ANH research. Systems: Researchers' recommended the establishment of a specialised ANH research ethics committee.

CONCLUSIONS

The findings highlight the significance of building ethics leadership and supporting ethical competency amongst researchers. Researchers recommended the development of tailored approaches rather than utilising generic governance systems and frameworks that are drawn from medical research and thus not fit for purpose in this field. In Malawi, specialised ethics review committees are needed to guide ANH research.

Obesity, political responsibility, and the politics of needs

Since overweight and obesity have been framed as one of the main contemporary health challenges in industrialized countries, it has become a matter of public health efforts. While the belief that obese individuals are personally responsible for their body weight prevails in public opinion, evidence-based health science widely acknowledges that obesity is significantly influenced by socio-economic factors and thus that prevention requires structural changes. This constellation bears the chance of politicizing an issue formerly conceived of as private which really is dependent on societal contingencies, such as the particular availability of food. Reflecting on the prevention of obesity from an ethical point of view, therefore, requires an elaborate concept of political responsibility. The core thesis of this paper is that existing approaches within the field of obesity ethics fall short in reasonably grasping the political dimensions at play, due to the prevailing individualistic understanding of responsibility. Drawing upon Iris Marion Young's concept of political responsibility, I propose an alternative approach that emphasizes the structural determinants of obesity. By arguing this way, obesity prevention comes into view as a public endeavor that involves public discourse as well as shared action. Political responsibility then cannot be discharged merely by intrusive governmental action nor by individuals on their own, but should be considered as a task all of us share. As I will sketch in the last part of the paper, this includes contesting discourses on interpretations of need. Thereby, the paper contributes to recognizing obesity as a social instead of an individual problem.

Ethical issues in the development and implementation of nutrition-related public health policies and interventions: A scoping review

Background

The limited integration of ethics in nutrition-related public health policies and interventions is one major concern for those who have the task of implementing them. Ethical challenges that are overlooked during the development of such interventions could raise serious ethical issues during their implementation and even after. As a result, these decision makers need technical support and ethical guidance for adaptation of interventions to local (cultural, social, economic, etc.) contexts.

Aim

The goal of this scoping review is to delineate and “map” the range of ethical issues in nutrition-related public health interventions, as well as the range of the various fields in which they may arise.

Methods

A scoping review of empirical research and conceptual literature was conducted following the framework of Arksey and O’Malley. Searches using PubMed with Medical Subject Headings (MeSH) categories and Advanced Search Builder as well as in the Global Health Library were performed. The final sample consists of 169 publications.

Results

The ethics of public health prevention or treatment of obesity and non-communicable diseases is the most explicitly and frequently discussed subject. In comparison, ethical issues raised by public health interventions in the fields of undernutrition, breastfeeding, vitamin/mineral supplementation and food fortification, food security, food sustainability and food safety are addressed in a lower proportion of the sample. The results illustrate the various natures, types, and scopes of existing public health nutrition-related interventions, and the various ethical issues that may be raised by these interventions, in addition to the numerous and different contexts in which they may be implemented.

Discussion

The ethical issues faced in the development and implementation of nutrition-related public health interventions are varied and cannot be equated with, nor generalized about, when dealing with specific activities in this field. More importantly, these ethical issues cannot be managed without a careful consideration for the complexity of contexts in which nutrition-related interventions are expected to be implemented. These interventions engage a variety of actors with diverse perspectives and interests. We discuss these challenges and also comment on the importance of considering ethical impacts in the monitoring and evaluation of such interventions.

Conclusion

General ethical frameworks or recommendations–although useful–cannot be expected to provide policy makers, implementators and other public health personnel with sufficient practical ethical guidance as they cannot consider and anticipate the particularities of all specific nutrition-related public health interventions and the complexity of the contexts in which they are implemented. Further research is needed in order to develop more targeted ethical frameworks.

Ethical issues in obesity prevention for school children: a systematic qualitative review

OBJECTIVES

Planning and conducting preventive measures against obesity for school children is beset with ethical issues which should be known to make well-informed decisions. The goal of this study was to provide a comprehensive spectrum of these ethical issues by means of a systematic review. In this context, the study also assesses the value of different search strategies for ethical literature in public health.

METHODS

Literature was searched in Medline, EBSCO and others. Three different search strategies with varied scopes were applied and their output was compared. Qualitative content analysis was used for extracting and categorizing ethical issues.

RESULTS

109 publications (published from 1995 to 2015) were finally included. The qualitative analysis resulted in 60 potentially relevant ethical issues. The three search strategies showed substantial differences regarding their search results.

CONCLUSIONS

The presented spectrum provides an initial evidence base for dealing with ethical issues adequately. The findings of the study further suggest that a broader scope is more fruitful for systematic reviews on ethical issues in the field of public health.

Ethical considerations in the implementation of nutrigenetics/nutrigenomics

Awareness of ethical issues that may be raised by the implementation of nutrigenetic/nutrigenomic (NGx) testing and personalized nutrition, at an individual or a public health level, is crucial to ensure the latter's sound and effective implementation. NGx tests that are currently offered or developed have different natures and scopes. We provide an example of NGx testing on the MTHFR gene to illustrate the current challenges when it comes to grasp the meaning of the results of such testing. In addition, NGx testing is developed within an evolving landscape of new genomic technologies and occurs at a time when public health policies mainly focus on preventive and predictive healthcare, with an emphasis on increased individual responsibility. The ethical issues raised by such a context and the genetic nature of NGx testing both should be carefully evaluated.

'Please, sir, can I have some more?' Food, lifestyle, diets: respect and moral responsibility

This article is about respect for food, responsibility for lifestyle and diet and responsibility for those who suffer from lack of food. After some general reflections on food, feasts, flatulence, taboos and waste, I argue that we have a responsibility to live a healthy lifestyle, but that there are also morally good reasons for taking risks with our health as we cherish other goals and values. Then I discuss situations, using the example of obesity, in which people are not free to choose their lifestyle. Governments and doctors have responsibilities in enabling people to chose healthy eating habits, e.g. by facilitating access to healthy foods and by criticizing scientifically unfounded weight loss diets. I continue to defend that we need to respect food and those who prepare it, and that we have a moral responsibility to contribute to the solution of the food gap in the world.
