“…During a 6month period of observation on children undergoing CAPD there was no significant fall in serum zinc or copper levels (A. R. Watson, unpublished observations). However serum levels do not reflect total body status of these trace elements and recommended intakes do not take account of the possible increased requirements during disease (Aggett & Davies, 1983).…”

This study was initiated to assess the dietary intakes of particular vitamins (A,D,B,2) and trace minerals [iron, zinc and copper) which we do not routinely supplement in children undergoing chronic peritoneal dialysis. Eight children were studied and all were receiving protein and energy supplements. The mean dietary intakes of the above micronutrients with the exception of Vitamins A and BIZ were below UK RDA values for chronological age but all were comparable to age and sex matched controls. No clinical deficiencies were detected in the short term but patients on long-term dialysis may require a more comprehensive vitamin and trace mineral supplement.

“…In children with or without diabetes a high intake of unrefined cereal carbohydrate in the first years of life dilutes energy concentration and could lead to undernutrition if energy supply is marginal (Rutishauser & Whitehead, 1972). The associated high phytate intake may theoretically compromise absorption of calcium, iron and zinc (Aggett & Davies, 1983;Francis, 1984;Bindra, 1985;Davies & Warrington, 1986).…”

Dietary advice for diabetes has changed significantly over the last ten years, the emphasis being on a total energy intake matched to individual requirements and on the physical as well as chemical structure of food and meals. It is recommended that energy intake is still distributed through the day as regular meals and snacks using a carbohydrate exchange system, but with 50% of dietary energy being derived from carbohydrate sources mainly in complex and unrefined form. This paper considers how far the dietary recommendations for adults can be applied to children.

“…There are potentially toxic elements with possible essential functions in low doses including lead, cadmium, mercury, arsenic, lithium, tin, aluminium [7]. Although these trace elements constitute a relatively small amount of the total body tissues, they are essential for many vital processes.…”

Background: Contraceptives are devices or techniques that permit sexual union without resultant pregnancy. Women on different contraceptive methods have been linked with the development of various diseases including changes in serum trace element levels. Therefore, the relationship between contraceptive use and trace elements needs to be investigated. This was a cohort study designed to determine the possible variations in serum concentrations of lead, copper, zinc and selenium in women practicing different contraceptive methods and attending family planning clinic at Abia State University Teaching Hospital, Aba, Southeast, Nigeria. Methods:Two hundred and forty (240) women within their reproductive age of 18-45 years were recruited for the study. sixty (60) women were on implants, sixty (60) were on intra uterine contraceptive device (IUCD) while sixty (60) were on combined oral contraceptive pills (COCP), the remaining sixty (60) women who were not on any contraceptive methods were recruited among the staff of the hospital and used as control group. 5 ml of venous blood sample was collected and dispensed into plain containers. Serum was processed and stored at -20˚C until assayed for lead, copper, selenium and zinc using atomic absorption spectrophotometer (AAS). Results:The result shows that the mean serum level of copper was significantly higher in women on all the contraceptive methods (Implants, IUCD and COCP) when compared with control group (p<0.05 respectively). However, the mean serum levels of selenium and zinc were significantly lower in women on different contraceptive methods when compared with control group (p<0.05 respectively). The mean serum copper (mg/dl) in women on implant and IUCD were significantly higher when compared with women on COCP (p<0.05 in each case) and significantly lower in implant than IUCD participants (p<0.05). The mean serum level of zinc (mg/dl) was significantly higher in women on COCP and IUCD compared with women on implant and significantly lower in COCP compared with women on IUCD (p<0.05 in each case). The mean serum level of selenium in women on COCP was significantly higher compared with women on implant and IUCD (p<0.05) and significantly lower in participants on implants than those on IUCD (p<0.05). Conclusion:The present study established a significant reduction in trace elements degrees suggesting possible deficiency of these minerals while significantly higher level of copper observed in women on all the contraceptive methods suggests potential risk of cardiovascular problems and oxidative stress in the affected women. It is therefore suggested that routine assessment of trace elements be recommended for women practicing various contraceptive methods in order to improve their quality of lives and easy management. have been associated with the use of contraceptives [4]. Some of these trace elements, for example zinc, selenium and manganese, are potent antioxidants known to be involved in preventing free radical induced damage. These antioxidants are invo...
