Adolescents are a vulnerable group to nutritional problems due to rapid growth requiring adequate nutrient intake. This study aimed to analyze the relationship between nutritional knowledge, eating habits, and micronutrient intake with the nutritional status of high school students in Kendari City. A cross-sectional design was applied with 345 students selected through proportional random sampling. Data were collected using a nutrition knowledge questionnaire, 24-hour dietary recall for micronutrient intake, and anthropometric measurements (BMI-for-age). Data were analyzed using chi-square tests and logistic regression. Results showed that most students had normal nutritional status (72.75%), while 9.28% were underweight, 12.17% overweight, and 5.80% obese. The majority had poor nutritional knowledge (67.54%) and unhealthy eating habits (67.2%). Micronutrient deficiencies were prevalent, particularly in vitamin A (83.19%), vitamin C (93.91%), vitamin D (85.22%), iron (68.70%), and calcium (97.39%). Statistical analysis revealed no significant relationship between nutritional knowledge or eating habits and nutritional status (p>0.05). However, vitamin A (p=0.003) and iron intake (p=0.004) were significantly associated with nutritional status. The findings suggest that biological factors, specifically micronutrient adequacy, play a more critical role in determining nutritional status than knowledge and dietary behavior
