Undernutrition problem is still widespread in developing countries, including Indonesia. On the other hand, overnutrition which is the nutritional problem in developed country, is beginning to flourish in the developing countries. The nutrinitonal imbalances might be caused by inappropriate amount of sleep due to inhibition of appetite regulation and changes in hormone production. Some of the nutrients that affect sleep pattern are macronutrients and micronutrients such as vitamin B, calcium, magnesium, and iron. This study was aimed to find out the correlation between nutritional status and sleep disorder. This was an observational analytical survey study with a cross sectional design. This study was conducted at elementary schools at Tikala, Manado using purposive sampling method. Weight and height of the respondents were measured to obtain the nutritional status. Parents were asked to fill the SDSC questionnaire to obtain the sleep disorder status. Of 249 (100%) respondents, 1 respondent (0.4%) categorized as malnutrition; 44 respondents (17,7%) categorized as undernutrition; 129 respondents (52.8%) categorized as normal; 34 respondents (13.7%) categorized as overweight; and 41 respondents (16.5%) categorized as obese. There were 156 respondents (62.7%) had sleep disorder meanwhile 93 respondents (37.3%) had no sleep disorder. The Pearson correlation test showed no significant correlation between nutritional status and sleep disorder (P>0,05). Conclusion: There was no signicant correlation between nutritional status and sleep disorder.Keywords: sleep disturbance, SDSC questionnaire, nutritional status Abstrak: Masalah gizi kurang masih tersebar luas di negara-negara berkembang, termasuk di Indonesia namun masalah gizi lebih yang merupakan masalah gizi di negara maju mulai terlihat juga di negara-negara berkembang. Ketidakseimbangan gizi dapat disebabkan tidak sesuainya jumlah tidur dikarenakan dihambatnya regulasi nafsu makan dan perubahan produksi hormon. Beberapa nutrisi yang dikaitkan memengaruhi tidur ialah makronutrien dan mikronutrien seperti vitamin B, kalsium, magnesium, dan zat besi.
