The School of Medicine is pleased to share a newly published research article by our academic staff member Dr Keresoma Leaupepe, co-authored with Fuimaono Darryl Pupi, in BMC Public Health.
“Selected food availability and sugar-related imports as indicators of dietary transition in Samoa, 2010–2023”
This research was also recently presented by Dr Leaupepe at the Pasifika Medical Association (PMA) Conference, providing an opportunity to share the findings with Pacific health professionals, researchers and colleagues and contribute to wider discussions on food systems, nutrition transition and the prevention of non-communicable diseases across the Pacific.
The study examines changes in Samoa's national food environment over a 14-year period using national food-availability and international trade data. It identifies important shifts in selected food indicators, including a substantial decline in the availability of selected traditional root crops, increasing vegetable-oil availability, persistently high sugar availability, and substantial growth in non-alcoholic beverage imports.
These findings provide contemporary evidence of changes in Samoa's food environment that are consistent with the broader nutrition transition occurring across Pacific Island countries. While the study does not measure individual dietary intake or establish causal relationships with non-communicable diseases, it highlights the importance of strengthening local food systems, promoting healthier food environments, and improving surveillance across health, agriculture and trade.
The research provides timely evidence that can contribute to ongoing discussions on nutrition policy, food systems and the prevention of diet-related non-communicable diseases in Samoa and the wider Pacific.
The article is now available online through BMC Public Health as an open-access, peer-reviewed publication.
Congratulations to Dr Leaupepe and Fuimaono Darryl Pupi on this important contribution to Pacific public health research.
