Abstract

Background: One of the public health problems that requires greater attention is anemia, especially among adolescent girls, because it has the potential to reduce health status, daily productivity, and disrupt learning concentration. Sleep duration and the adequacy of iron intake are suspected to be factors influencing hemoglobin status. Objective: This study aimed to analyze the relationship between sleep duration and the adequacy of iron intake with hemoglobin levels among adolescent girls. Methodology: This analytic observational study with a cross-sectional design was conducted on 33 female students selected using a total sampling technique. The study was carried out at Sekolah Islam Terpadu Aulia Cendekia during November–December 2025. Sleep duration data were obtained from the Pittsburgh Sleep Quality Index (PSQI) questionnaire, iron intake was collected through the Semi Quantitative Food Frequency Questionnaire (SQ-FFQ), and hemoglobin levels were measured using an Hb meter. Data analysis was performed using the Chi-Square test to determine the relationship between variables with SPSS software. Results and Discussion: Most students have abnormal hemoglobin levels (66.7%), insufficient sleep duration (51.5%), and low iron intake (57.6%). The analysis shows a significant relationship between insufficient sleep duration and low hemoglobin levels (p=0.010; OR=9.643), as well as a significant correlation between inadequate iron intake and low hemoglobin levels (p=0.024; OR=7.111). Conclusion: Insufficient sleep duration and low iron intake are significantly associated with hemoglobin levels in adolescent girls; therefore, intervention through nutrition education and improvement of sleep patterns is needed as an effort to prevent anemia.

Abstract

Background: Elementary school children's nutritional knowledge remains low, potentially leading to unhealthy eating behaviors and long-term health risks. Traditional educational methods tend to be less engaging for children, necessitating an interactive approach that can enhance understanding and motivation to learn. Objective: This study aimed to evaluate the effect of online game-based nutrition education on school children's knowledge of healthy eating. Methods: The study used a quasi-experimental pre-test and post-test design with 60 students in grades 4-6 of elementary school in District X. The research instrument was a validated nutritional knowledge questionnaire consisting of 20 multiple-choice questions regarding healthy food types, balanced nutrition, and good eating habits. The intervention was conducted for 2 weeks, with each session lasting 20–30 minutes. Data were analyzed using a paired t-test with a significance level of p < 0.05. Results: The study showed a significant increase in students' nutritional knowledge scores after participating in online game-based education, with the average score increasing from 12.5 ± 3.2 to 17.8 ± 2.5 (p < 0.001). This indicates that the intervention was effective in improving children's understanding of healthy eating. Conclusion: Online game-based nutrition education has been shown to be effective in improving schoolchildren's knowledge of healthy eating. This method is recommended as a fun and interactive nutrition learning strategy, with long-term potential to shape healthy eating behaviors from an early age.
