1. 研究了8名营养不良儿童的补偿性或“追赶性”生长与食物摄入、食物利用效率和身体成分变化的关系。在恢复期间，生长速度是同年龄正常儿童的15倍，是同身高或体重正常儿童的5倍。快速生长与高食物摄入量有关。当达到身高的预期体重时，食物摄入量突然下降30%，增长率下降到与该身高和体重的正常儿童相当的水平。粮食转化率数字表明，在快速增长期间，粮食利用效率总体上有所提高。一旦达到身高的预期体重，体脂百分比就会增加。体重增加率与Miller-Payne方程预测的差异很难解释：讨论了与该方程相关的问题。
1. Compensatory, or ‘catch-up’, growth in eight malnourished children has been studied in relation to food intake, efficiency of food utilization and changes in body composition.2. During recovery, growth rates were fifteen times as fast as those of normal children of similar age, and five times as fast as those of normal children of a similar height or weight.3. Rapid growth was associated with a high food intake.4. When the expected weight for height was reached food intakes fell abruptly by 30% and growth rates dropped to a level comparable with those of normal children of that height and weight.5. Food conversion figures suggest an over-all increase in the efficiency of food utilization during rapid growth.6. The percentage body fat increased, once the expected weight for height was reached.7. Differences in the rates of weight gain from those predicted by the Miller-Payne equation were difficult to interpret: problems associated with the equation are discussed.
