Length and weight measurements obtained on 142 vegetarian and 229 nonvegetarian school children from a normative population were fitted to growth curves using the asymptotic nonlinear regression equation of Jenss and Bayley. All of the children were Caucasian and age ranged from a few weeks to 6 yr. The growth curves obtained for vegetarian children were from 0.5 to 1.0 kg and 1 to 2 cm lower, depending on age, sex, and diet, than were curves for reference populations of nonvegetarian children. Length was affected more than weight. Macrobiotic vegetarian children's curves were more depressed than those of the other vegetarian children, indicating that there was a good deal of heterogeneity in growth within vegetarians which was associated with dietary group characteristics. Measurements of females were more consistently affected than males, and their diets were also more far reaching with respect to animal food avoidances. The analysis of food records available provided evidence that energy intakes of the vegetarians were below recommended levels, whereas protein intakes did not appear to be limiting.
对来自正常人群的142名素食学童和229名非素食学童进行了身高和体重测量，并使用Jenss和Bayley的渐近非线性回归方程将其拟合到生长曲线。所有儿童均为白种人，年龄从几周至6岁不等。根据年龄、性别和饮食的不同，素食儿童的生长曲线比非素食儿童参考人群的曲线低0.5至1.0千克和1至2厘米。身高受到的影响比体重更大。长寿素食儿童的曲线比其他素食儿童的曲线更低，这表明素食儿童群体内部在生长方面存在很大的异质性，这与饮食组特征有关。女性的测量结果比男性更一致地受到影响，而且她们在避免食用动物性食物方面的饮食也更为严格。对现有食物记录的分析表明，素食者的能量摄入量低于推荐水平，而蛋白质摄入量似乎没有受到限制。
