Sir,
We carried out a detailed survey of the adult population in the remote Amerindian indigenous village (Santa Mission) Guyana, South America. The village is home to approximately 200 people of mainly Arawak descent, where there is no health care.[1] The approximately 740,000 people living in the country is made up out of Amerindians (5.3%), Blacks (30.5%), East Indians (51.4%), Chinese (0.2%), White (2.1%), and Mixed (10%).[1] Population mix of the country lends itself to anthropological, social, lifestyle, and genetic studies which may yield important information.[2]
We previously reported our pilot data in which we screened 619 people in Guyana.[3] This work was part of the SEVAK Project in Guyana and India.[4]
There were several similarities in the characteristics of the Amerindian indigenous people and the nonindigenous people. There was no difference in the age, marital status, access to clean drinking water, incidence of smoking, alcohol use, or drug abuse. None of the homes had indoor toilets while 83.6% had indoor toilets in the nonindigenous people. The prevalence of diabetes mellitus was 13.9%, and that of hypertension was 29.4% in the nonindigenous group versus 5.4% and 12.5%, respectively, in the indigenous group [Table 1].
We were intrigued by the prevalence of diabetes and hypertension in the two groups. The low incidence of these conditions could be attributed to a variety of reasons such as nomadic lifestyle, genetic, or unknown factors. The incidence of obesity between the two groups was similar. This is in contrast to the high incidence of diabetes and hypertension in the native American-Indians in the US.[5]
