Q4Abstract
Introduction: Chronic Energy Deficiency (CED) among adolescent girls remains a major nutritional problem in Indonesia and may affect growth, reproductive health, and future pregnancy outcomes. Nutrition education through video-based media is considered an effective strategy to improve nutrition knowledge and dietary behavior among adolescents. Objective: This study aimed to determine the effect of video-based nutrition education on nutrition knowledge, energy intake, protein intake, and nutritional status among adolescent girls with CED. Methods: A quasi-experimental study with a pretest-posttest control group design was conducted among 88 adolescent girls with CED at SMA Negeri 3 Wajo, Indonesia. Participants were divided into an intervention group (n=44) and a control group (n=44). The intervention group received video-based nutrition education for eight weeks. Nutrition knowledge was assessed using a structured questionnaire, dietary intake was measured using a 24-hour food recall, and nutritional status was evaluated using Mid-Upper Arm Circumference (MUAC). Data were analyzed using non-parametric statistical tests with a significance level of p<0.05 Results: The intervention significantly improved nutrition knowledge (p<0.001) and energy intake (p=0.035). Protein intake increased after the intervention, although the difference was not statistically significant (p=0.052). Improvements in nutritional status were also observed, with 31.8% of participants in the intervention group changing from CED to normal nutritional status. Food security was identified as the most influential factor associated with nutritional status improvement (OR=7.188; p=0.022). Conclusions: Video based nutrition education effectively improves nutrition knowledge, energy intake, and nutritional status among adolescent girls with CED and can be considered a practical strategy for preventing and reducing CED among adolescents.
