Selenium intakes of children from rural Malawi and Papua New Guinea (PNG)
- Univ. of Guelph, Ontario (Canada) Papua New Guinea Inst. of Medical Research, Medang (Papua New Guinea)
Selenium intakes of 66 rural Malawian children aged 4-6 y consuming maize-based diets were compared with those of 67 Papua New Guinea (PNG) children aged 6-10 y with diets based on bananas, sweet potatoes, and sago. Representative samples of all staple foods consumed were collected, dried, ground and subsequently analyzed for Se by instrumental neutron activation analysis using {sup 77}Se. Median Se intakes for the Malawian children determined by weighed 3-day records at 3 seasons of the year were: harvest 20 {mu}g/d, 1.24 {mu}g/kg; postharvest 21 {mu}g/d, 1.24 {mu}g/kg; preharvest 15 {mu}g/d, 0.96 {mu}g/kg. For the PNG children the median intake during the rainy season, assessed from two 24 hr interactive recalls, was 20 {mu}g/d, 0.89 {mu}g/kg. Four food groups contributed to {ge}95% of the total Se intake for both the Malawian and the PNG children. Of the children, 55% of the Malawian and 87% of the PNG had average Se intakes {lt} US Recommended Dietary Allowances (RDA); 16% and 48% respectively, had intakes {lt}66% US RDA. Average Se intakes were below those reported for US and Australian children but above those of children from New Zealand where Se intakes are low.
