简要总结
The goal of this study is to evaluate the effectiveness of a nutrition health education intervention among ethnic minority children aged 5-16 years in Tra Vinh Province, Vietnam. It will also assess factors associated with nutritional status in this population.
The main questions it aims to answer are:
Does the nutrition health education intervention improve nutritional status? Does the intervention improve nutrition-related knowledge, attitudes, and practices (KAP)? Does the intervention improve diet quality and physical activity levels among participants?
Researchers will compare participants receiving the nutrition education intervention with control group to evaluate the effectiveness of the intervention.
Participants in intervention group will:
Participate in a structured nutrition education program delivered monthly for 4 months through interactive lessons, videos, and educational materials Receive ongoing support and reinforcement activities for an additional 2 months Attend baseline and follow-up assessments including anthropometric measurements and interviews Complete questionnaires on nutrition knowledge, dietary practices, and physical activity

研究组 & 干预措施
intervention group
Participants receive a structured nutrition health education intervention delivered through community-based and school-based models. The program includes four monthly educational sessions using presentations and videos, supported by interactive posters, nutrition leaflets, and dietary and physical activity diaries. The intervention is implemented over four months, followed by a two-month maintenance phase with reinforcement activities involving community health workers, school staff, and family engagement.
干预措施: Nutrition Health Education (Behavioral)
control group
Participants do not receive the structured nutrition education intervention. They continue to receive routine health and nutrition education activities available at local community health centers and schools without additional intervention from the study.
