Nine of the ten most obese countries on Earth are in the Pacific
In short: A recent Lancet analysis reveals a staggering reality: Pacific island nations dominate the global rankings for obesity. This is not merely a health crisis, but a complex intersection of climate change, shifting colonial legacies, and the rising cost of nutrition.
New data from 2022 shows that over 1 billion people globally are living with obesity, with adult rates worldwide having more than doubled since 1990. However, the scale of the crisis is most acute in the Pacific. Analysis published in the Lancet found that Pacific island countries account for nine out of the ten nations with the highest prevalence of obesity among men and women aged 20 and above. In some regions, the impact is visible in the rising frequency of strokes among Fijian patients in their 20s and 30s, a phenomenon previously rare in those under 70.
The drivers of this epidemic are deeply structural. Dr. Mark Jacobs of the WHO notes that while unhealthy foods are often cheap and heavily advertised, accessing healthy alternatives is becoming increasingly difficult due to droughts, floods, and rising seas caused by climate change. This is compounded by a historical shift in diet; in places like Fiji, the rise in average BMI correlates with an increase in processed food imports. In Nauru, historical interventions by colonial powers in the 1910s to mitigate famine introduced new foods, and by the 1920s, missionary influence even changed cooking methods, such as frying fish rather than eating it raw.
Cultural perceptions also play a role. In Nauru, obesity has historically been viewed as a sign of wealth, and the Nauruan term for feeling healthy, *pweda*, is synonymous with fullness or distension. In the Cook Islands, food habits are tied to social hierarchy. Addressing this requires more than just medical intervention; health leaders at the Fifteenth Pacific Health Ministers Meeting in Tonga committed to a multi-sectoral approach, involving ministries of trade, agriculture, and environment to tackle the complex economic and environmental roots of the epidemic.
