Moderate childhood wasting is defined as having a weight-for-height Z-score (WHZ) < -2, but > or = -3. These children are typically given fortified corn/soy blended flour (CSB), but this intervention has shown limited effectiveness. Fortified spreads (FS) can be used as supplementary foods instead; they are energy-dense, lipid-based pastes with added powdered micronutrients. In this randomized clinical effectiveness trial, the recovery rates were compared among children with moderate wasting who received either milk/peanut FS, soy/peanut FS, or CSB. Children received isoenergetic quantities of food, 314 kJ x kg(-1) x d(-1), for up to 8 wk with biweekly follow-up. The primary outcome was recovery, defined as having a WHZ > -2. Time-event analysis was used to compare the recovery rate. A total of 1362 children were enrolled in the study. Children receiving soy/peanut FS had a similar recovery rate to those receiving milk/peanut FS and children in either FS group were more likely to recover than those receiving CSB (80% in both FS groups vs. 72% in the CSB group; P < 0.01). The rate of weight gain in the first 2 wk was greater among children receiving milk/peanut FS (2.6 g x kg(-1) x d(-1), n = 465) or children receiving soy/peanut FS (2.4 g x kg(-1) x d(-1), n = 450) than among children receiving CSB (2.0 g x kg(-1) x d(-1), n = 447; P < 0.05). Rates of length gain did not differ among the 3 groups. A total of 8% of children in each feeding group developed edema, indicative of severe malnutrition, while receiving supplemental feeding. We conclude that FS are superior supplementary foods to CSB for moderately wasted Malawian children.
中度儿童消瘦的定义为身高别体重Z评分(WHZ)<-2,但≥-3。这些儿童通常会被给予强化玉米/大豆混合面粉(CSB),但这种干预措施的效果有限。强化涂抹酱(FS)可用作补充食品;它们是富含能量、以脂质为基础的糊状物,并添加了微量营养素粉末。在这项随机临床疗效试验中,对接受牛奶/花生FS、大豆/花生FS或CSB的中度消瘦儿童的康复率进行了比较。儿童按等能量摄入量进食,即314 kJ×kg⁻¹×d⁻¹,持续8周,每两周进行一次随访。主要结局指标为康复,定义为WHZ>-2。采用时间-事件分析来比较康复率。共有1362名儿童参与了该研究。接受大豆/花生FS的儿童与接受牛奶/花生FS的儿童康复率相似,且任一FS组的儿童比接受CSB的儿童更有可能康复(两个FS组均为80%,CSB组为72%;P<0.01)。在最初2周内,接受牛奶/花生FS的儿童(2.6 g×kg⁻¹×d⁻¹,n = 465)或接受大豆/花生FS的儿童(2.4 g×kg⁻¹×d⁻¹,n = 450)的体重增加率高于接受CSB的儿童(2.0 g×kg⁻¹×d⁻¹,n = 447;P<0.05)。三组儿童的身长增加率没有差异。在接受补充喂养期间,每个喂养组共有8%的儿童出现水肿,这表明存在严重营养不良。我们得出结论,对于马拉维中度消瘦的儿童,FS是优于CSB的补充食品。
