• 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).
• Participants in Tessekere (Senegal) reported more consumption of '10. fish and shellfish' than participants in Estarreja (Portugal) and Caribbean Coast (Guadeloupe).
• 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).
• A Kruskal-Wallis test found statistically significant differences in average household size (p < 0.01), ranging from large households (over 9 individuals) in Tessekere (Senegal) to small households (2 to 3 individuals) in the Caribbean Coast (Guadeloupe) and Estarreja (Portugal).
• A Kruskal-Wallis test revealed that interviewed participants were significantly older in the Caribbean Coast (Guadeloupe) and Estarreja (Portugal) regions compared to other study sites (p < 0.01).
• 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 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 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.
• 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.
