Body mass index of the Kandeganvila veddas
(The Sri Lanka Medical Association. Colombo, 1994) Wikramanayake, E.R.; Wickramanayake, T.W.; Chandrasekera, M.S.
BMI was calculated from the heights and weights of 37 Veddas (18 males and 19 females) measured in 1971/73 when they were living at Kandeganvila, and of 247 veddas (109 males and 138 females) measured in 1993/94 at Hennanigala South of Mahaweli System 'C', ten years after their change of habitat. Significantly lower BMI's (p0.05) was observed in the preadolescent children, bth males and females, in 1993/94. In general in the adults too a trend towards lower BMI's judged by BMI, of the relocation of the Kandeganvila veddas has been detrimental.

The prevalence and mode of inheritance of median diastema in the Sinhalese
(University of Colombo. Colombo, 2003) Dissanayake, U.; Chandrasekera, M.S.; Wikramanayake, E.R.
Variation in blood pressure with age and sex of the Uva-Bintenne Veddas
(University of Colombo. Colombo, 2004) Wikramanayake, E.R.; Chandrasekera, M.S.
The blood pressure of 496(227 males and 269 females) Uva -Bintenne veddas in the age range 1 to 80 years were recorded at Hennanigal South and Dambana. In both males and females there is no progressive increase of pressure with age. In the females both curves are more variable with the systolic pressure higher than in the males except in the age range 31-40 and the diastolic pressure higher up to 50 years. When compared with a 1989 study of a rural breeding isolate of the sinhalese the pressures of both males and females were significantly higher in the age range 1-15 years with no steep rise of the curve from 1-18 years. The aetiology of the difference is postulated to be genetic rather than environmental.
