项目摘要

DESCRIPTION (provided by applicant): Rapid Weight Gain among Infants of Low Income Hispanic Immigrant Mothers In the US, the number of children who are overweight or obese has tripled since the 1980's. Children from low income Hispanic families have disproportionately high rates of obesity. Recent research provides evidence that rapid weight gain in the first year of life is associated with sharply increased risk of obesity at 3 years of age. Further, early childhood obesity persists through later development with untoward health consequences over a lifetime, including diabetes and cardiovascular disease. The Institute of Medicine (IOM) report, Early Childhood Obesity Prevention Policies, refutes the long held notion that infants outgrow "baby fat" and has made recommendations for the prevention of rapid infant weight gain that leads to later obesity. However, childhood obesity research to date has focused predominantly on school age children with almost no attention to risk factors that begin in infancy. The proposed project addresses this gap by focusing on a sector of the US population at high risk for obesogenic morbidities, namely, infants of low income Hispanic immigrant mothers. Today, more than one-fourth of the nation's population under 1 year of age is Hispanic and most mothers of these children were born outside the US. Guided by the Life Course Health Development model and the IOM's early infancy obesity prevention recommendations, the proposed study will examine the influence of early infant feeding practices, physical activity opportunity, and sleep duration on rapid weight gain. Perception of a healthy child weight and food security will be tested for their influence on early feeding practices and subsequent infant weight gain. Using a prospective infancy cohort design, data will be gathered through interviews with 300 Hispanic mothers and medical chart review. Our overall purpose is to examine the IOM obesity-prevention recommendations for early infant feeding practices, physical activity opportunity, and sleep duration in relation to risk for rapid weight gain among infants of low income Hispanic immigrant mothers. Specific Aim 1 will explore the influences of infant feedng practices, perception of healthy child weight and food security in the first 6 months of life on rapid weight gain by 12 months of age. Specific Aim 2 will explore the added contribution of physical activity opportunity and sleep duration during the first 6 months to rapid weight gain by 12 months of age, after controlling for early feeding practices, perception of healthy child weight and food security. The study will be conducted in a large pediatric primary care setting that serves low income Hispanic immigrant families in Virginia. Results will inform the prevention of rapid infant weight gain with evidence that can be translated into clinical practice. Specific Aim will implement a mentorship program, Mason's Maternal-Child Health Equity Scholars, to expose undergraduate nursing students from disadvantaged backgrounds and/or racial and ethnic groups underrepresented in biobehavioral research to maternal-child health equity research. Student learning and satisfaction will be assessed with measures from the university's Students as Scholars program and adapted for this BRITE initiative.

描述（由申请人提供）：低收入西班牙裔移民母亲的婴儿体重快速增加在美国，自 20 世纪 80 年代以来，超重或肥胖儿童的数量增加了两倍。来自低收入西班牙裔家庭的儿童肥胖率异常高。最近的研究提供的证据表明，出生第一年体重快速增加与三岁时肥胖风险急剧增加相关。此外，儿童早期肥胖症在以后的发展中持续存在，并在一生中造成不良的健康后果，包括糖尿病和心血管疾病。美国医学研究所 (IOM) 的报告《儿童早期肥胖预防政策》驳斥了长期以来婴儿长大后会不再出现“婴儿肥”的观点，并提出了预防婴儿体重快速增加导致日后肥胖的建议。然而，迄今为止，儿童肥胖研究主要集中在学龄儿童，几乎没有关注婴儿期开始的危险因素。拟议的项目通过关注美国肥胖发病高危人群（即低收入西班牙裔移民母亲的婴儿）来解决这一差距。如今，全国超过四分之一的 1 岁以下人口是西班牙裔，这些孩子的大多数母亲都出生在美国境外。在生命全程健康发展模型和国际移民组织的婴儿早期肥胖预防建议的指导下，拟议的研究将研究早期婴儿喂养方式、体力活动机会和睡眠时间对体重快速增加的影响。将测试对健康儿童体重和食品安全的看法，以了解其对早期喂养方法和随后婴儿体重增加的影响。采用前瞻性婴儿队列设计，通过对 300 名西班牙裔母亲的访谈和医疗图表审查来收集数据。我们的总体目的是检查 IOM 针对早期婴儿喂养方式、体力活动机会和睡眠时间的肥胖预防建议，以及低收入西班牙裔移民母亲的婴儿体重快速增加的风险。具体目标 1 将探讨婴儿喂养方式、对健康儿童体重的认知以及出生后 6 个月内的食品安全对 12 个月龄时体重快速增加的影响。具体目标 2 将探讨在控制早期喂养习惯、对健康儿童体重的认知和食品安全后，前 6 个月内的体力活动机会和睡眠时间对 12 个月大时体重快速增加的额外贡献。该研究将在一个大型儿科初级保健机构中进行，该机构为弗吉尼亚州的低收入西班牙裔移民家庭提供服务。结果将为预防婴儿体重快速增加提供信息，并提供可转化为临床实践的证据。具体目标将实施一项导师计划，即梅森母婴健康公平学者计划，让来自弱势背景和/或在生物行为研究中代表性不足的种族和民族群体的本科护生接触母婴健康公平研究。学生的学习和满意度将根据大学学生学者计划的衡量标准进行评估，并根据 BRITE 计划进行调整。
