回顾性地确定了 19 名因 .gtoreq 而选择的肥胖儿童在减肥之前和期间的身高变化速度。体重相对于身高下降 10%。减重期的平均持续时间为 9.7 个月。所有儿童均接受均衡热量缺乏饮食，每天每公斤理想体重含有 1.5-2.0 克蛋白质。通过计算每个人的 Z 分数来标准化高度速度。体重减轻之前，身高速度的平均 (.+-.SD) Z 得分为 2.32 .+-。 2.47 U.11名患者为.gtoreq。 2 SD 高于年龄和性别的平均身高速度。在减重过程中，身高速度的平均 Z 得分显着下降至 0.62 .+/-。 2.37 U. 减肥前和减肥期间 Z 分数的变化与体重变化显着相关，但与体重身高变化无关。即使是中等限制性饮食也可能与线性生长速度的降低有关。这些观察结果对减肥带来的其他不良后果的风险的影响尚不清楚。讨论了在轻度限制性饮食治疗期间仔细监测肥胖儿童的重要性。
Height velocities prior to and during weight reduction were determined retrospectively in 19 obese children selected because of a .gtoreq. 10% fall in weight for height. Mean duration of the weight reduction period was 9.7 mo. All children were treated with a balanced calorie-deficit diet containing 1.5-2.0 g of protein/kg of ideal body weight per day. Height velocities were normalized by calculating the Z score for each one. Prior to weight reduction, the mean (.+-. SD) Z score for height velocity was 2.32 .+-. 2.47 U. Eleven patients were .gtoreq. 2 SD above the mean height velocity for age and sex. During weight reduction, the mean Z score for height velocity decreased significantly to 0.62 .+-. 2.37 U. The change in Z score before and during weight reduction was significantly correlated with the change in weight but not with the change in weight for height. Even midly restrictive diets may be associated with a reduction in linear growth velocity. The implications of these observations for the risk of other adverse consequences of weight reduction are not clear. The importance of careful monitoring of obese children during mildly restrictive dietary therapy is discussed.
