The present study investigated the relationship between a number of anthropometric indices and behavioral development during the first 2 years of life in rural Guatemala. Length and weight were the indices most strongly correlated with behavioral development. If the effect of the infant's length and weight was statistically controlled for, none of the other anthropometric variables explained a significant proportion of the variance in behavioral development. Controlling the length (or weight) assessed at the same age as the behavioral assessment, length (or weight) for younger ages was not significantly correlated with behavioral development. Changes in length or weight over time correlated with changes in behavioral performance. We were unable to explain the association between physical growth and behavioral development by a number of variables including gestational age, nutrient intake, prevalence of disease, and familial characteristics.
本研究调查了危地马拉农村地区儿童出生后头两年内一系列人体测量指标与行为发育之间的关系。身长和体重是与行为发育相关性最强的指标。如果对婴儿身长和体重的影响进行统计学控制，其他人体测量变量均无法解释行为发育变异的很大比例。控制与行为评估年龄相同的身长（或体重）后，较年轻年龄段的身长（或体重）与行为发育无显著相关性。身长或体重随时间的变化与行为表现的变化相关。我们无法通过包括胎龄、营养摄入、疾病患病率和家庭特征在内的多个变量来解释身体生长与行为发育之间的关联。
