这是对INCAP纵向研究（1969-77）及其后续研究（1988-89）的设计和方法的概述。第一项研究的目的是评估宫内和学龄前营养不良对生长和智力发育的影响。为了实现这一目标，向居住在危地马拉四个村庄的孕妇和幼儿提供了食物补充剂。两个村庄提供高蛋白高能量饮料，另两个村庄提供无蛋白低能量饮料，两种补充剂都含有维生素和矿物质。在出生后的头7年里，收集了关于身体发育、智力发育、补品的出席和消费、家庭饮食、发病率以及家庭特征的纵向信息，还收集了母亲的健康和营养数据。INCAP后续研究是对第一次研究的前参与者进行的横断面评估，并在受试者11-27岁时进行。INCAP后续研究的假设是，儿童早期营养的改善会促进青少年和成人人力资本的形成，收集了有关身体发育和身体组成、成熟度、工作能力、智力表现和学业成绩的数据。
This is an overview of the design and methods of the INCAP longitudinal study (1969-77) and its follow-up study (1988-89), The first study had the objective of assessing the effects of intrauterine and preschool malnutrition on growth and mental development, To achieve this, food supplements were provided to pregnant women and young children residing in four Guatemalan villages. Two villages were given a high-protein, high-energy drink and two were provided a no-protein, low-energy drink, Both supplements contained vitamins and minerals. Longitudinal information was collected during the first seven years of life on physical growth, mental development, attendance and consumption of supplement, home diet, morbidity and on characteristics of the family, Health and nutrition data on mothers also were collected. The INCAP followup study was a cross-sectional evaluation of former participants of the first study and was carried out when the subjects were 11-27 y old. The hypothesis of the INCAP follow-up study was that improved nutrition in early childhood leads to enhanced human capital formation in adolescents and adults, Data were collected on physical growth and body composition, maturation, work capacity, intellectual performance and school achievement.
