PROJECT SUMMARY/ABSTRACT Children in low-income families and who are racial/ethnic minorities are disproportionately affected by risk factors for obesity in the first 24 months of life, such as lower rates of exclusive breastfeeding and higher rates of food insecurity. Reaching over 7 million low-income, racially diverse participants, the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) is in an important position to improve dietary patterns in early childhood, a critical developmental period for establishing lifelong eating habits. A federal requirement of WIC is to identify nutritional risk of children and provide nutrition education to all low-income families served by the program. The effectiveness of this counseling is directly related to the effectiveness of nutrition screening measures. Currently, WIC programs around the country use nutrition questionnaires to assess nutrition risk of all infants and young children and use results to determine counseling services based on these assessments. Few of these questionnaires are validated, however, and none have proven predictive validity to identify obesity and diet quality at 24 months of age. Our long-term goal is to identify effective dietary strategies to prevent obesity and reduce disparities in low-income infants and toddlers. The overall objective of this proposed study is to better understand how diet patterns during a critical time period during infancy are associated with risk for obesity in the first 24 months of life. This work is relevant to my K01 award because my research with school-aged children has led me to identify ways to improve nutrition earlier in life. Children as early as 24 months have already established dietary habits that can impact long-term weight and health. We will use data from the first-ever national cohort of WIC-enrolled children followed longitudinally from ages 0 to 24 months in the USDA’s WIC Infant and Toddler Feeding Practices Study-2 (WIC ITFPS-2). WIC ITFPS-2 collects extensive data on diet, feeding behaviors, and anthropometry from the largest, most diverse cohort of WIC participants studied to date. Finally, this study will provide the preliminary evidence for a R01 proposal to conduct a randomized controlled trial to test if targeting nutritionally at-risk infants for more specific WIC nutrition education services compared to providing standard education services reduces obesity disparities in a low-income population.

项目摘要/摘要 低收入家庭和种族/族裔少数民族的儿童受风险的影响不成比例 肥胖的因素在生命的前24个月中，例如较低的独家母乳喂养率和较高的比率 粮食不安全。特殊补充有超过700万低收入，大致多样化的参与者 妇女，婴儿和儿童（WIC）的营养计划是改善饮食的重要位置 幼儿时期的模式，这是建立终身饮食习惯的关键发展时期。联邦 WIC的要求是确定儿童的营养风险，并为所有低收入提供营养教育 该计划服务的家庭。这项咨询的有效性与 营养筛查措施。目前，全国各地的WIC计划都使用营养问卷 评估所有婴儿和幼儿的营养风险，并使用结果来确定基于咨询服务 在这些评估中。但是，这些问卷中很少有验证，但没有证明的预测性 有效性以确定24个月大的肥胖和饮食质量。我们的长期目标是确定有效的饮食 预防肥胖和减少低收入婴儿和幼儿的分布的策略。总体目标 这项拟议的研究是更好地了解婴儿期关键时期的饮食模式如何 在生命的头24个月中与肥胖风险有关。这项工作与我的K01奖有关，因为我的 与学龄儿童的研究使我确定了早期改善营养的方法。儿童为 早在24个月就已经建立了可能影响长期体重和健康的饮食习惯。我们 将使用有史以来第一个全国WIC注册儿童的数据，从0岁到0岁 在USDA的WIC婴儿和幼儿喂养实践研究2（WIC ITFPS-2）中24个月。 WIC ITFPS-2 收集有关饮食，喂养行为和人体测量法的广泛数据 WIC参与者迄今为止研究了。最后，这项研究将为R01提案提供初步证据 进行一项随机对照试验，以测试是否针对营养处于危险中的婴儿使用更具体的WIC 与提供标准教育服务相比，营养教育服务减少了肥胖 低收入人群。
