摘要

儿童肥胖影响着亚利桑那州近28%的儿童，对低收入家庭的影响尤为严重，这凸显了长期营养干预的必要性。营养&；健康意识（NHA）课程是为四年级学生设计的为期五周的健康教育课程，旨在提高健康知识，自我效能，以及与体育活动，营养和慢性疾病预防有关的态度。虽然以前的研究表明干预后立即得到改善，但尚未评估健康知识的持续保留情况。目的评价NHA项目在提高小学生健康知识和态度方面的效果，并评估一年的保留情况。研究设计、设置、参与者一项前后纵向研究在艾默生小学进行，这是一所位于亚利桑那州梅萨的一级学校。112名符合条件的四年级学生每周上五次面对面的课。主题包括体育活动、营养、心脏病和糖尿病。在干预后基线、干预后1周、干预后4周和干预后1年分别对15个概念知识和12个态度问题进行双语问卷调查。可测量的结果/分析主要结果是健康知识得分从基线到随后每个时间点的变化。配对t检验评估干预前和干预后的评分差异。次要结局包括自我报告的健康行为态度。结果在67名测试前后匹配的参与者中，平均知识得分从8.3上升到10.3 (p <；0.01)，显示出显著的短期知识收益。一年后，53名参与者被重新评估，平均得分为10.0 -显示无显著下降（p = 0.15）。健康态度调查表明，采取更健康行为的信心和意愿不断提高。结论NHA课程显著提高了学生的健康知识和态度，干预后1年知识保留率保持不变。西班牙语翻译的评估报告解决了语言障碍，强调了具有文化能力的健康教育的重要性。这些发现强调了早期以学校为基础的干预在塑造终身健康行为和减轻慢性病风险方面的关键作用，强调了将全面健康教育纳入儿科外展工作的必要性。该项目显示出持久的效益，可以为改善弱势社区公共卫生结果的可扩展战略提供信息。FundingNone

An Evaluation of the Nutrition and Health Awareness (NHA) Program on the Health Knowledge and Attitudes of Elementary School Students: A One-Year Retention Study

Background

Childhood obesity affects nearly 28% of children in Arizona, disproportionately impacting low-income families and highlighting the need for long-term nutritional interventions. The Nutrition & Health Awareness (NHA) program is a five-week health education curriculum designed for fourth-grade students, aiming to improve health knowledge, self-efficacy, and attitudes related to physical activity, nutrition, and chronic disease prevention. While previous studies demonstrated immediate post-intervention improvements, sustained retention of health knowledge has not yet been evaluated.

Objective

To evaluate the effectiveness of the NHA program in enhancing health knowledge and attitudes among elementary school students and assess one-year retention.

Study Design, Settings, Participants

A pre-post longitudinal study was conducted at Emerson Elementary School, a Title I school in Mesa, Arizona. Five weekly in-person lessons were delivered to 112 eligible fourth-grade students. Topics covered physical activity, nutrition, heart disease, and diabetes. A bilingual questionnaire consisting of 15 conceptual knowledge and 12 attitude questions was administered at baseline, one week, four weeks, and one year post-intervention.

Measurable Outcome/Analysis

The primary outcome was the change in health knowledge scores from baseline to each subsequent time point. Paired t-tests assessed pre- and post-intervention score differences. Secondary outcomes included self-reported health behavior attitudes.

Results

Among 67 participants matched from pre- to post-test, average knowledge scores increased from 8.3 to 10.3 (p < 0.01), demonstrating significant short-term knowledge gains. One year later, 53 participants were reassessed, with an average score of 10.0—showing a non-significant decline (p = 0.15). Health attitude surveys indicated consistent improvements in confidence and intentions to adopt healthier behaviors.

Conclusions

The NHA curriculum significantly improved health knowledge and attitudes, with knowledge retention maintained one year post-intervention. Spanish-translated assessments addressed language barriers, emphasizing the importance of culturally competent health education. These findings underscore the critical role of early, school-based interventions in shaping lifelong health behaviors and mitigating chronic disease risk, reinforcing the necessity of integrating comprehensive health education into pediatric outreach efforts. Demonstrating lasting benefits, this program could inform scalable strategies to improve public health outcomes in vulnerable communities.

期刊介绍： The Journal of Nutrition Education and Behavior (JNEB), the official journal of the Society for Nutrition Education and Behavior, is a refereed, scientific periodical that serves as a global resource for all professionals with an interest in nutrition education; nutrition and physical activity behavior theories and intervention outcomes; complementary and alternative medicine related to nutrition behaviors; food environment; food, nutrition, and physical activity communication strategies including technology; nutrition-related economics; food safety education; and scholarship of learning related to these areas. The purpose of JNEB is to document and disseminate original research and emerging issues and practices relevant to these areas worldwide. The Journal of Nutrition Education and Behavior welcomes evidence-based manuscripts that provide new insights and useful findings related to nutrition education research, practice and policy. The content areas of JNEB reflect the diverse interests in nutrition and physical activity related to public health, nutritional sciences, education, behavioral economics, family and consumer sciences, and eHealth, including the interests of community-based nutrition-practitioners. As the Society''s official journal, JNEB also includes policy statements, issue perspectives, position papers, and member communications.
