The purpose of this study was to analyze the correlation between nutritional knowledge, nutritional intake and sleep duration with overweight indicators among Public Health female students year 2014-2016. This study used a cross-sectional design. The subjects  were 100 female students year 2014-2016 who had BMI ≥18,5 kg/m² and selected by stratified random sampling. Data were collected by interviews using structured quistionnares, physical activity recall, body fat percentage and waist circumference measurements.

The results showed that 87% of the subjects has good knowledge, 64% lack of sleep, 84% had low energy adequacy levels, 92% had excessive saturated fat, 82% had excessive unsaturated fat, 100% had simple carbohydrates excess, 32% had percentage body fat in obese category and 19% waist circumference excess. There were correlations between energy adequacy level (r = -0.3531; p = 0.001) and simple carbohydrate intake (r = 0.321; p = 0.001) with body fat percentage. There were correlation between energy adequacy level (r = -0.313; p = 0.002), saturated fat intake (r = 0.202; p = 0.044) and simple carbohydrate intake (r = 0.254; p = 0.011) with waist circumference. It is suggested for the students to reduce the fat and sweet food.
