Nauru has the highest obesity rate in the world. 97 per cent of men and 93 per cent of women are overweight or obese.[6] In 2011, the average body mass index was around 34.5. Nauru's obesity rates have been attributed to overconsumption of imported ultra-processed food from an economic downturn from the end of phosphate mining in the region,[7] which also led to 80% of Nauru's land being unsuitable for agriculture.[8][9][10]

The Nauru Public Health Centre offers treatments for diabetes and other obesity-related diseases. This is the only form of specialized medical care. Patients who require additional treatment travel to Australia.[13][14]
