RESUMO

Physical activity is beneficial for children's well-being. The effect of dietary supplementation on children's physical activity in food-insecure areas remains little studied. We examined the effects of a lipid-based nutrient supplement (LNS) on children's objectively measured physical activity in a randomised, controlled, outcome-assessor-blinded trial. Mothers of the children received one capsule daily of Fe-folic acid (IFA), one capsule containing eighteen micronutrients (MMN) or one 20 g sachet of LNS (containing twenty-two MMN, protein, carbohydrates, essential fatty acids and 494 kJ (118 kcal)) during pregnancy and for 6 months thereafter. Children in the IFA and MMN groups received no supplementation, and these groups were collapsed into a single control group; children in the LNS group received 20 g LNS from 6 to 18 months. We measured physical activity with accelerometers over 1 week at 18 months. The main outcome was mean vector magnitude counts/15 s. Of the 728 children at the beginning of child intervention at 6 months, 570 (78 %) provided sufficient data for analysis. The mean accelerometer counts for the 190 children in the LNS group and for the 380 children in the control group were 303 (sd 59) and 301 (sd 56), respectively (P for difference=0·65). LNS, given to mothers during pregnancy and 6 months postpartum and to their infants from 6 to 18 months of age, did not increase physical activity among 18-month-old children.

RESUMO

BACKGROUND AND OBJECTIVES: Severe anaemia is an important cause of mortality in developing countries. However, few studies have explored the use of and possibilities for blood transfusion services. The aims of this study are to explore the use of blood transfusion services at a hospital in sub-Saharan Africa and to assess the quality of the transfusion services according to WHO guidelines. MATERIALS AND METHODS: Patient age, gender, haemoglobin (Hb) level, diagnosis, hospital department and replacement donations were recorded for all blood transfusions administered at a district hospital in Malawi in January 2010. The laboratory equipment and procedures were scored according to WHO guidelines. RESULTS: The mean Hb of transfused patients was 4·8 g/dl. Fifty-seven per cent (59/104) of the transfusions were given to children diagnosed with malaria, and 17% (18/104) were given to pregnant women. During the study period, blood was in stock and available for transfusion within 1 h of requisition. The equipment and procedures at this hospital met the main criteria for an adequate WHO stage of development. CONCLUSION: In contrast to the advanced transfusion medicine in developed nations, our findings highlight the persistent and urgent need for life-saving blood transfusions in especially young children and pregnant women in Africa. The results indicate that blood transfusion services adapted to local conditions may be a realistic solution for providing safe blood products in developing countries. Serious challenges, such as HIV transmission and sustainable organization of low-risk blood donations should be addressed to assure access to safe blood products.
