The aim of our study is to determine the nutritional status and habits, nutritional knowledge, and obesity/overweight prevalence of university students staying in dormitories. The study is a cross-sectional study conducted in Bolu city center between December 2020 and February 2021, among university students who live in dormitories affiliated with the Ministry of Youth and Sports. It was carried out with the participation of 309 students. A questionnaire form including general information, health information, questions about nutrition and consumption habits, physical activity form, anthropometric measurements, food consumption frequency form, Nutrition Knowledge Level Scale for Adults (NKLSA) was applied as a data collection tool in the study. The mean age of the students is 21±0.1 years and 50.8% of them are women. 69.6% of the individuals are normal, 23.0% are overweight / obese and 7.4% are underweight. Most of the students (75.7%) did not take courses on health/nutrition. For 55% of students who miss the main meal, the most missed meal is lunch and the least skipped meal is evening meal. It has been determined that the frequency of eating dinner out of the students increases as they go to upper classes. Basic nutrition and food preference scores of female students were found higher than male students. There is no difference between the nutritional knowledge levels of the students according to BMI (Body Mass İndex) groups. The basic nutrition and food preference scores of the senior students were found to be higher than the first grade students. Food preference scores of students who took courses on nutrition/health were found to be higher. Although the nutritional knowledge level of the last year students is higher, it is seen that the frequency of eating outdoors increases as the class level increases. Therefore, it is just as important for individuals to have sufficient knowledge as well as to transform information into a way of behavior and to gain healthy eating habits. The eating habits of students who stay in dormitories for certain periods may change over time. Therefore, students should be followed in their nutritional behaviors and educations should be given regularly in order to increase the awareness of students about making the right food choice in daily life, adequate and balanced nutrition, and physical activity.
