项目摘要

DESCRIPTION (Provided by Applicant): The general aims of this study are to evaluate the interaction of temperament and feeding in infants to determine its impact on infant weight gain. The problem of pediatric obesity is cause for serious concern, as some 6 million American children are fat enough to signal a real public health problem. The health implications are sobering, as diabetes, fatty liver, and obstructive sleep apnea in childhood may foreshadow coronary heart disease or even cancer in adulthood. In recent years, rates of overweight in infancy have increased across all ethnicities, exceeding those of preschool-aged children. While persistent overfeeding or low physical activity might seem to be the explanation for excessive early weight gain, studies of energy intake and expenditure in infancy have reported conflicting results. Because low-income, minority children who are formula-fed appear to be a population at particular risk for obesity, yet little investigated in infancy, this study will enroll an urban sample of 50 black and 50 Hispanic mother-infant dyads. Mothers will be enrolled in the study a day after giving birth, with some maternal and infant data collected at that time, and when the infants are approximately 3-, 6-, and 12-months or age. Data collected will consist of health records, maternal reports of feeding and ratings of infant irritability, mechanical measures of motor activity, and observations of a feeding. The specific aims of the proposed project are to assess maternal feeding in response to infant temperament; to determine how infant temperament contributes to infant weight gain; and to evaluate the independent impact of activity, irritability, and feeding patterns on infant weight gain using a multivariate model.

描述（由申请人提供）：本研究的总体目标是评估婴儿气质和喂养的相互作用以确定它对婴儿体重增加的影响。小儿肥胖问题的根源引起严重关注，因为大约 600 万美国儿童肥胖得足以标志着一个真正的公共卫生问题。对健康的影响是发人深省的，因为儿童期糖尿病、脂肪肝和阻塞性睡眠呼吸暂停可能预示成年后患冠心病甚至癌症。近年来，比率所有种族的婴儿期超重人数均有所增加，超过了学龄前儿童。当持续过量喂食或体力低下时活动似乎是早期体重过度增加的原因，关于婴儿期能量摄入和消耗的研究报告了相互矛盾的情况结果。因为配方奶喂养的低收入少数民族儿童似乎是肥胖风险特别高的人群，但在这方面的研究却很少在婴儿期，这项研究将招募 50 名黑人和 50 名西班牙裔城市样本母婴二元体。母亲将在给予一天后参加该研究出生时收集了一些母婴数据，以及当婴儿大约为 3 个月、6 个月和 12 个月或年龄。收集的数据将包括健康记录、母亲喂养报告和婴儿评级烦躁、运动活动的机械测量以及对喂养。拟议项目的具体目标是评估孕产妇根据婴儿的性情喂养；如何判断婴儿的气质有助于婴儿体重增加；并评估独立影响活动、烦躁和喂养方式对婴儿体重增加的影响多元模型。
