DESCRIPTION (provided by applicant): The aims of this study are to evaluate the interaction of temperament and dietary factors in early human development in order to determine their impact on weight gain. The increase in pediatric obesity is of great concern, as close to 6 million American children are fat enough to signal a significant public health problem. The health implications are serious, as diabetes, fatty liver and obstructive sleep apnea in children may foreshadow heart disease, or even cancer in in adulthood. In recent years, rates of overweight even among infants and young children have increased across all ethnicities, but especially minorities. While persistent overfeeding or low physical activity might seem to explain 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, this study will enroll a sample of 100 low-income black and Hispanic mother-infant dyads (30 black and 70 Hispanic dyads), to track the infants over their first 5 years of development. Mothers will be recruited at WIC in the first few weeks after giving birth. Dyads will be visited in the families' homes when the infants are approximately 3, 6, and 12 months of age, and subsequently when they are 2, 3, 4, and 5 years old. Data collected will consist of demographic information, anthropometrical measures, maternal reports of infant/child eating patterns, maternal ratings of infant/child temperament, mechanical estimates of infant/child activity, ratings of maternal regulation of feeding, and measures of child development, self-esteem, and the home environment. The specific aims of the project are to assess maternal regulation of feeding in response to temperament, to determine how activity, difficulty, and sociability contribute to infant/child weight gain, and to evaluate the interactive impact of temperament factors, maternal behavior, and energy intake on excess childhood weight gain and other outcome measures.

描述（由申请人提供）：本研究的目的是评估气质和饮食因素在人类早期发育中的相互作用，以确定它们对体重增加的影响。儿童肥胖的增加令人高度关注，因为近 600 万美国儿童的肥胖程度足以表明存在严重的公共健康问题。 对健康的影响是严重的，因为儿童的糖尿病、脂肪肝和阻塞性睡眠呼吸暂停可能预示着成年后患心脏病，甚至癌症。近年来，所有种族的婴儿和幼儿超重率都有所上升，尤其是少数族裔。虽然持续的过度喂养或体力活动不足似乎可以解释早期体重过度增加的原因，但对婴儿期能量摄入和消耗的研究却报告了相互矛盾的结果。因为低收入、少数民族儿童 配方奶喂养的人群似乎是肥胖风险特别高的人群，这项研究将招募 100 名低收入黑人和西班牙裔母婴二人组（30 名黑人和 70 名西班牙裔母婴）作为样本，以追踪婴儿的第一胎5年的发展。 WIC 将在分娩后的最初几周内招募母亲。当婴儿大约 3、6 和 12 个月大时，以及随后在他们 2、3、4 和 5 岁时，将到婴儿家中探访二人组。收集的数据将包括人口统计信息、人体测量测量、婴儿/儿童饮食模式的母亲报告、婴儿/儿童气质的母亲评级、婴儿/儿童活动的机械估计、母亲喂养调节的评级以及儿童发育、自我评估的测量。 -尊重和家庭环境。该项目的具体目标是评估母亲根据气质对喂养的调节，确定活动、难度和社交性如何影响婴儿/儿童体重增加，并评估气质因素、母亲行为和能量的相互作用影响儿童体重增加过多和其他结果指标的摄入量。
