A cross-sectional nutritional survey was tarried out on 350 elderly Malays
aged 60 and above from 11 randomly selected villages in a rural area on the
East Coast of Malaysia.
The findings indicated that the mean intakes of energy and all of the nutri
ents investigated were below the Malaysian Recommended Dietary Allowances,
excepts for protein and vitamin C. Nutrients most likely to be inadequate w
ere vitamin A, thiamine, riboflavin, niacin and calcium, with more than 50%
of the subjects having estimated intakes of below 2/3 of the recommendatio
ns. However, vitamin A status was adequate, with only 2 subjects being bioc
hemically deficient (plasma retinol less than or equal to 0.7 mmol/l), Appr
oximately a third of the subjects had hypoalbuminaemia (plasma albumin < 3.
3 g/dl) and anaemia (Haemoglobin < 12 g/dl for men; < 13 g/dl for women), R
iboflavin deficiency, as assessed by an erythrocyte glutathione reductase a
ctivation coefficient (EGRAC) of more than 1.35 was identified in 77% of th
e subjects. The prevalence of vitamin E deficiency (plasma alpha-tocopherol
less than or equal to 12 mmol/l) was 27%, with men being at a greater risk
.
In conclusion, the dietary intakes of these rural elderly Malays was inadeq
uate. Over three quarters of the sample were biochemically deficient in rib
oflavin, the functional consequences of which need to be further investigat
ed.
