• The PC1 gradient distinguishes the dietary patterns of Tessekere (Senegal) from those of the Caribbean Coast (Guadeloupe) and Oyapock (French Guiana).
• Participants are incrementally less likely to declare bad health when residing in Oyapock (French Guiana), Estarreja (Portugal), or the Caribbean Coast (Guadeloupe) as opposed to Tessekere (Senegal).
• The study titled 'Associations between dietary diversity and self-rated health in a transverse study of four local food systems (French Guiana, Guadeloupe, Portugal and Senegal)' was published in BMC Public Health in 2025.
• The study was conducted across four Human-Environment Observatories (OHM): OHMi-Tessekere (Senegal), OHMi-Estarreja (Portugal), OHM-Littoral Caraïbe (Guadeloupe), and OHM-Oyapock (French Guiana).
• The superposition of participants from Oyapock (French Guiana) with those from the Caribbean Coast (Guadeloupe) in the study suggests that Oyapock may be experiencing a dietary transition similar to that of the Caribbean Coast.
• The prevalence of diabetes and obesity is higher in French Guiana and Guadeloupe compared to northern Portugal and the Ferlo region of Senegal, and these rates are among the highest in all of France.
• In the study, the Dietary Diversity Score (DDS) for Estarreja, Portugal, was comparable to those for the Caribbean Coast (Guadeloupe) and the Oyapock River (French Guiana).
• The Caribbean Coast (Guadeloupe) and the Oyapock River region (French Guiana) exhibit similar and high Dietary Diversity Scores (DDS), with meat consumption serving as a key indicator of their dietary typology.
• In Guadeloupe and French Guiana, indigenous and introduced foods coexist, interact, and may hybridize, while ultra-processed foods are common and their impact on health aligns with Popkin’s nutrition transition model.
• The study 'Associations between dietary diversity and self-rated health in a transverse study of four local food systems (French Guiana, Guadeloupe, Portugal and Senegal)' examines dietary diversity and self-rated health across four specific local food systems: French Guiana, Guadeloupe, Portugal, and Senegal.
• The study aimed to evaluate the relationship between food consumption and subjective health across four distinct socio-ecosystems in Portugal, Senegal, French Guiana, and Guadeloupe.
• The study interviewed 465 individuals aged 18 years and older from Senegal, French Guiana, Guadeloupe, and Portugal using 24-hour dietary recalls and non-probability sampling methods.
• The French overseas territories of Guadeloupe and French Guiana exhibit high prevalence of chronic non-communicable diseases like diabetes, overweight, and obesity, which corresponds to the fourth nutritional transition model (degenerative diseases) defined by Popkin.
• The article 'Associations between dietary diversity and self-rated health in a transverse study of four local food systems (French Guiana, Guadeloupe, Portugal and Senegal)' is identified by the DOI https://doi.org/10.1186/s12889-025-21872-8.
• Dietary patterns of participants from Caribbean Coast (Guadeloupe) and Oyapock (French Guiana) are characterized by food groups ‘7. meat’, ‘8. processed meat’, ‘9. eggs’, ‘5. ripe fruits’ and ‘2. roots, tubers and other starchy foods’, a pattern labeled “animal protein of terrestrial origin and high starch”.
• The study conducted a transverse comparison of foods consumed in four local socio-ecosystems: French Guiana, Guadeloupe, Portugal, and Senegal, using 24-hour dietary recalls.
• The study authors conducted data collection and analysis in specific geographic fields: PD, AK, and EM in Senegal; RR, PJL, and MR in Guadeloupe; DD and JL in French Guiana; and JPB, EFS, NED, and MR in Portugal.
• The ranking of mean Dietary Diversity Scores by region, from highest to lowest, is Caribbean Coast (Guadeloupe), Oyapock (French Guiana), Estarreja (Portugal), and Tessekere (Senegal).
• The study conducted interviews and dietary assessments at four specific locations during 2023: OHMi Tessekere (Senegal) from 26/05/2023 to 20/07/2023; OHMi Estarreja (Portugal) from 23/03/2023 to 15/10/2023; OHM Littoral-Caraïbe (Guadeloupe) from 19/03/2023 to 27/09/2023; and OHM Oyapock (French Guiana) from 04/04/2023 to 21/06/2023.
