来自危地马拉4个村庄的妇女和儿童参加了一项为期7年的自愿食品补充计划。在其中2个村庄，他们获得了维生素和矿物质强化的高蛋白卡路里补充剂。在另外两个村庄，维生素矿物质强化补充剂不含蛋白质和相对少量的卡路里。定期对3-7岁的儿童进行认知测试，并进行人体测量。在几个时间点收集了家庭社会环境的测量值。多元回归分析表明，营养和社会环境措施与认知能力的各个维度有关。营养摄入与社会因素无关，对认知发展有明显影响。有一些证据表明，接受高蛋白卡路里补充剂的儿童（其母亲在怀孕和哺乳期间接受了高蛋白卡路里补充剂）更有可能在认知表现上取得高分。这些结果，虽然没有减少社会环境对认知功能差异的解释，但表明营养干预计划在欠发达国家的农村地区有益。
Women and children from 4 Guatemalan villages participated in a voluntary food supplementation program for 7 yr. In 2 of the villages they received a vitamin and mineral fortified, high-protein calorie supplement. In the other 2 villages, the vitamin-mineral fortified supplement contained no protein and a relatively small number of calories. Cognitive tests were administered regularly to children ages 3-7, and anthropometric measures obtained. Measures of families'' social milieu were collected at several points in time. Multiple regresssion analysis shows that nutritional and social environmental measures are related to various dimensions of cognitive competence. Nutritional intake, independent of social factors, evidently affects cognitive development. There is some evidence that the children who receive the high-protein calorie supplement (and whose mothers received it during pregnancy and lactation) are more likely to score high in cognitive performance These results, while not diminishing social environmental explanations of differences in cognitive function suggest benefits from nutrition intervention programs in rural areas of lesser-developed countries.
