Abstract

Adolescent nutrition is a critical issue in the development of national health. Factors such as physical activity, dietary patterns, and nutrition education significantly influence nutritional status. This study aims to examine the relationship between nutritional knowledge, the consumption of sugar-sweetened beverages, and physical activity with the nutritional status of eighth-grade students at SMP Nawa Kartika, Tegal Regency. The research employed a quantitative cross-sectional design. The sample consisted of 50 eighth-grade students selected through total sampling. Primary data were collected using three instruments: a nutritional knowledge questionnaire, a beverage consumption questionnaire, and a physical activity questionnaire. Data were analyzed using the Chi-Square test. The findings reveal that there is no significant correlation between nutritional status and nutrition knowledge (p = 0.181). However, a significant correlation was found between nutritional status and physical activity (p = 0.05), as well as with the habit of consuming sugar-sweetened beverages (p = 0.01). These results indicate that dietary patterns and physical activity play an essential role in determining students’ nutritional status. The study highlights the importance of promoting healthier consumption habits and increasing physical activity levels among adolescents as part of public health strategies.
