Pacific Island Nations Had the World's Highest Obesity Rates in 2021

Several Pacific Island nations have the highest rates of obesity in the world. According to 2021 data from the World Population Review, Nauru has the highest rate at 61%, meaning 61% of its population suffers from morbid obesity.

Cook Islands holds the second position with an obesity rate of 55.9%, followed by Palau and the Marshall Islands at 55.3% and 52.9% respectively.

The Marshall Islands' obesity rate is recorded at 52.9%, while Tuvalu's is at 51.6%.

Research from Oxford University indicates that the high obesity rates in many Pacific Island nations are due to a shift in dietary habits following World War II. Previously, the populations of these nations consumed large amounts of fish, meat, and locally grown fruits and vegetables. These have been largely replaced by rice, sugar, flour, canned meats, and beer.

Furthermore, obesity in Pacific Island nations is influenced by cultural factors, and public education on diet and obesity reduction remains low.

For information, obesity is a chronic condition resulting from an excessive accumulation of body fat. It is triggered by lifestyle changes, increased consumption of processed foods, and high-calorie diets.

Obesity is also linked to increased mortality rates from heart disease, diabetes, and various cancers. The number of deaths among obese individuals with these comorbidities is higher than among those with normal weight.
