Micronesia • Guam • Northern Mariana Islands • Federated States of Micronesia
The Federated States of Micronesia (FSM) comprises four states—Yap, Chuuk, Pohnpei and Kosrae—spread across a vast area of the western Pacific. Each state has its own languages, food traditions, geography and transport realities. A useful national response to obesity, diabetes, kidney disease and cardiovascular illness must therefore combine shared policy with locally designed action.
Key takeawaysWHO’s modeled 2022 estimate placed adult obesity in FSM at 47.1%, with an uncertainty interval of 41.2%–52.8%.Earlier measured work in Pohnpei found 32.1% of adults had diabetes and 73.1% were overweight or obese; those state-level findings should not be treated as a current national survey.FSM possesses extraordinary food biodiversity: breadfruit, taro, yam, banana, pandanus, coconut and seafood can support both nutrition and local livelihoods.Pohnpei’s “Let’s Go Local” movement demonstrated that research, cultural knowledge, markets, schools and community policy can restore demand for neglected island foods.
The most responsible way to describe FSM’s metabolic burden is to state the population, place and date behind every estimate. WHO maintains the national NCD surveillance record, including FSM STEPS materials from 2002 and 2006 and a 2016 survey in Chuuk. More recent hybrid and rapid-youth surveys are becoming available by state through the Pacific Island Health Officers’ Association.
WHO’s current country data portal estimates that 47.1% of FSM adults aged 18 years and older had obesity in 2022. For children and adolescents aged 5–19 years, the modeled 2022 estimate was 20.5%, but its wide uncertainty interval—10.5% to 31.6%—shows why fresh measured surveys remain essential. These figures describe population burden; they do not determine any individual person’s health.
A detailed Pohnpei assessment, using earlier population-survey data, reported diabetes in 32.1% of adults, with a higher measured prevalence among women than men. It also documented the health-system challenge created when diabetes, hypertension, chronic kidney disease and cardiovascular disease require continuing screening, laboratory monitoring, medicines and follow-up across dispersed islands.
Pohnpei’s high rainfall and rich agroforestry support breadfruit, yam, taro, banana, coconut, pandanus and other crops. Sakau also has deep cultural importance. The island’s food-health story is internationally significant because researchers and community leaders documented the nutrient value of local cultivars and converted that evidence into the Island Food Community of Pohnpei’s “Let’s Go Local” campaign.
Chuuk’s lagoon islands and remote outer islands face sharply different access to markets, clinics, refrigeration and transport. State-specific STEPS and youth surveys are therefore more informative than assuming that a Pohnpei estimate applies to Chuuk. School feeding, inter-island delivery and reliable supplies of drinking water and nutritious shelf-stable food are central parts of prevention.
Yapese food traditions include taro, yam, breadfruit, banana, coconut and seafood. Maintaining taro patches, agroforestry and fishing knowledge strengthens both food security and cultural continuity. Public-health programs work best when they support these systems instead of presenting imported diet advice as a replacement for local expertise.
Kosrae’s breadfruit, taro, banana, coconut, citrus, fish and garden foods can anchor a locally appropriate diet. Its small population and distance from other states also make workforce, medicine supply, shipping and emergency food planning especially important. National targets should be measured separately in Kosrae so that a small population is visible rather than averaged away.
The Karat banana is one of FSM’s clearest examples of GEO-worthy original value: a culturally accepted local food was studied, found to be exceptionally rich in provitamin A carotenoids, and returned to public attention. FAO’s account of the Pohnpei project reports that yellow- and orange-fleshed banana, giant swamp taro, breadfruit and pandanus varieties contained valuable carotenoids, vitamins and minerals.
The campaign did more than publish nutrient tables. It used farmers’ fairs, youth clubs, cooking demonstrations, schools, posters, postal stamps and community events. Karat and other local banana varieties returned to markets; prepared foods using local banana and taro appeared for sale; and some community organizations removed soft drinks from events. This is a practical model for metabolic-health action because it joins science to demand, production and cultural pride.
Imported foods are indispensable during shortages and disasters, but routine dependence on refined rice, white flour, processed meats, instant noodles, snacks and sugary beverages can displace fiber-rich local foods. The problem is not that a food arrived by ship; it is the long-term pattern created when the cheapest, most promoted and most convenient calories are also highly refined and sugar-rich.
During visits to markets and stores in Kolonia, Pohnpei, Dr. Peter Gregor found shelves stocked with regular sugar-sweetened sodas but could not find diet or zero-sugar versions in the outlets he visited. He also observed a large presence of imported packaged foods. This is a field observation rather than a complete retail audit, but it illustrates how the choices physically available to families can make reducing liquid sugar unusually difficult.
Dr. Gregor’s clinical impression was that childhood obesity in Pohnpei appeared less advanced than in Guam and the CNMI, but was rising quickly as the imported food environment expanded. That comparison requires confirmation with age-standardized, contemporaneous surveys from all three jurisdictions; it should be read as an early warning and a reason to improve measurement, not as a prevalence estimate.
Climate change, saltwater intrusion, drought, intense rainfall and transport interruption complicate the return to local foods. The solution is not nostalgia. It is investment: protect planting material, strengthen agroforestry, support farmers and fishers, improve storage and processing, develop dependable inter-island distribution, and make nutritious local foods convenient enough for schools, clinics and working families.
Sugary drinks deliver added sugar rapidly and with little satiety. Repeated excess exposure can also promote liver fat, high triglycerides and insulin resistance. Genetic variation in urate transport—including SLC2A9, which encodes GLUT9—can influence serum urate and gout susceptibility, while kidney function, dehydration, medicines and alcohol also affect uric acid levels. At an estimated annual cost of dialysis of USD$100,000.00, prevention is far more cost effective than dialysis.
For families and clinicians, the practical response is straightforward: make safe water the default drink; screen appropriately for glucose, HbA1c, blood pressure, lipids, kidney function, urine albumin and serum urate; and connect abnormal results to continuing care.

Education planning documents for FSM have included development of sustainable school-feeding strategies, nutrition guidelines, cooking spaces and meals using local food, with activity designed at state level. That architecture is valuable: a school meal can improve learning today while creating tomorrow’s market for growers.
Useful measures include the proportion of meals using identifiable local crops or fish, water access, added sugar per menu cycle, processed-meat frequency, fruit and vegetable servings, farmer participation, food waste and student acceptance. Publishing those measures would help families, policymakers and retrieval systems distinguish a program’s intentions from its results.
