About this Research Topic

Background

Obesity has become a pandemic problem over the last 20-30 years, largely driven by the ongoing nutrition transition worldwide. Low- and Middle-Income Countries (LMICs) are experiencing this transition at a faster rate than High-Income Countries (HICs), primarily due to high urbanization rates that necessitate rapid, short-term adaptive strategies, which are often obesogenic. This transition is marked by changing dietary habits and sedentary lifestyles, particularly within rapidly urbanizing environments, leading to the development of Obesity-Related Metabolic Diseases (ORCDs) such as hypertension and type 2 diabetes. In sub-Saharan African populations, the prevalence of obesity and ORCDs is increasing more rapidly than in HICs, with an absolute annual increase of overweight/obesity at 1.3% in West African urban women. Despite the complex, multi-factorial etiology of obesity, most studies adopt a uni-disciplinary approach—psychological, sociocultural, physiological, or genetic—potentially contributing to the current failure to prevent obesity, whose prevalence has tripled since 1975 according to the WHO. The biocultural background of populations is often insufficiently considered, limiting our understanding of their adaptive capacity to new urban environments and their exposure to ORCD risks. While genetic determinants of obesity are well understood, their systemic interactions and effects on body weight regulation remain poorly explored. Additionally, the pathways predicting ORCDs between sociodemographic indirect determinants (age, sex, education, urban lifetime duration, etc.) and socio-ecological direct determinants (dietary intake and physical activity) are rarely studied, necessitating a more comprehensive approach to understanding the etiology of ORCDs.

This Research Topic aims to refocus the study of obesity from an anthropological perspective, considering the holistic characteristics of populations—both sociodemographic and socio-ecological—that influence their adaptation to obesogenic urban environments. The goal is to provide new insights for developing anthropologically relevant, targeted programs to prevent and treat obesity and ORCDs. By addressing the respective and cumulative contributions of various drivers and the multiple pathways leading to ORCDs, this Research Topic aims to explain the differences in prevalence and incidence of ORCDs between countries and better identify at-risk subgroups.

To gather further insights into the biocultural determinants of obesity-related cardiometabolic diseases, we welcome articles addressing, but not limited to, the following themes:

• Sociodemographic factors influencing obesity and ORCDs.
• Socio-ecological determinants such as dietary intake and physical activity.
• Interdisciplinary qualitative, quantitative, or mixed-methods approaches combining psychological, sociocultural, physiological, and genetic perspectives.
• Comparative studies between LMICs and HICs.
• Adaptive strategies in urban environments.
• Pathways linking sociodemographic and socio-ecological factors to ORCDs.
• Development of targeted prevention and treatment programs based on anthropological insights.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
