Nutritional rehabilitation in Bangladesh--the importance of zinc

Our aim was to investigate whether zinc deficiency becomes apparent during nutritional rehabilitation and limits the rate of weight gain. Twenty-five severely malnourished children, who were admitted to the Children's Nutrition Unit in Bangladesh, were alternately allocated to two groups. Their mean dietary Zn intake was 3.7 mg/d and mean caloric intake greater than 150 kcal.kg-1.d-1; one group received a daily Zn supplement of 50 mg for 2 wk. During the first week, weight gain was similar in the two groups, but during the second week, weight gain was 73% more in the Zn-supplemented group (8.83 +/- 1.56 vs 5.09 +/- 1.62 g.kg-1.d-1). The 95% confidence limits were 0.88 less to 8.36 g.kg-1.d- 1 more gain in children receiving Zn supplements. The results strongly suggest that Zn supplements are beneficial to severely malnourished children during nutritional rehabilitation. Polymorphonuclear (PMN) cell Zn increased in the group receiving Zn supplements (p less than 0.001), confirming that the Zn content of PMN cells reflects available Zn.
