Asian Indian migrants have a strikingly high diabetes prevalence but prevalence in India has been considered to be relatively low. However, there have been few recent studies, especially in rural India. A house-to-house survey was undertaken in a defined area of Eluru, a small town in South India, and in four adjoining villages. A total of 9563 subjects (4729 male, 4834 female) were surveyed, of whom 5699 lived in Eluru and 3864 in the four villages. Enquiry was made for known diabetes in each household. In all, 157 known diabetic subjects (89 male, 68 female) were ascertained. The prevalence of known diabetes was 6.1% in all subjects aged 40 or over and rose to 13.3% in the age group 50-59 years. The overall crude prevalence of known diabetes was 1.6% (1.9% male, 1.4% female). The prevalence in Eluru (1.5%) was similar to that in the four villages (1.9%). The age-adjusted rates for known diabetes in the middle-aged and elderly subjects are unexpectedly high, considering the poor socio-economic circumstances, decreased health awareness and decreased access to medical facilities, and are comparable with those of similar surveys in relatively affluent Delhi, and in Southall, London. The prevalence in rural (as well as urban) India may be much higher than previously realised. Large formal prevalence studies are urgently required.
