Aims/Introduction. To know the prevalence of obesity, metabolic syndrome, impaired fasting glycemia and diabetes in the population of Bali.Materials and Methods. A cross-sectional study enrolling 1840 subjects, aged 13-100 years with male-to-female ratio of 972/868, were studied at seven villages across the island of Bali.Results: The prevalence of central obesity was 35% (male, 27.5%; female, 43.4%); metabolic syndrome (MS), 18.2% (male, 16.6%; female, 20.0%); impaired fasting glycemia (IFG), 13.1% (male, 14.3%; female, 12.4%); and diabetes mellitus (DM), 5.9% (male, 6.1%; female, 5.7%). The subjects who had 1, 2, 3, 4, and 5 components of MS were 34.6%, 23.8%, 13.0%, 4.3%, and 0.9% respectively. The population in two tourist areas (Legian and Ubud) had the highest prevalence of central obesity (61.2% and 70.1%), but they did not necessarily have a higher prevalence of DM. The two tourist areas (Legian, 24.1%; and Ubud, 21%) as well as Sangsit village (23.3%) have the highest prevalence of MS.Conclusions. The prevalence of obesity, MS, IFG and DM were comparatively low. Analysis across the villages revealed that higher prevalence of central obesity was not necessarily associated with higher prevalence of DM. There is a need to further study the risk of obesity on MS and DM in tourist areas of Bali.
