Keywords:
sedentary lifestyle, nutritional status, nutrition knowledgeAbstract
Background: Adolescence is a growth period requiring adequate nutrition and physical activity for optimal development. However, increasing sedentary behavior and low understanding of balanced nutrition are suspected to influence the nutritional status of adolescents. Purpose: This study aimed to analyze the relationship between sedentary lifestyle, the level of knowledge regarding balanced nutrition, and nutritional status among adolescents at SMPN 1 Solokuro, Lamongan. Methods: The study employed a quantitative approach using an analytic observational method and a cross-sectional design. A total of 60 students from grades VII–IX were selected as respondents using total sampling. Nutritional status was determined based on the Body Mass Index-for-Age (BMI-for-Age) index, sedentary behavior was measured using the Adolescent Sedentary Activity Questionnaire (ASAQ), and the level of knowledge regarding balanced nutrition was assessed via a test instrument. Analysis of the relationships between variables was conducted using the Spearman Rank Test with a significance level of α=0.05. Result: The results showed that 60% of respondents had good nutritional status, 66.7% fell into the moderate sedentary lifestyle category, and 50% had a sufficient level of knowledge regarding balanced nutrition. Statistical analysis revealed no significant relationship between sedentary lifestyle and nutritional status (p=0.187), nor between the level of knowledge regarding balanced nutrition and nutritional status (p=0.542). Conclusion: Adolescent nutritional status is likely influenced more by other factors, such as dietary intake, socioeconomic conditions, and geographical factors. Therefore, schools need to strengthen education on balanced
nutrition and encourage the adoption of an active lifestyle to support adolescent health.
