In the last few years, reports have shown an indication that the lack of thiamin(Vitamin B1) in female university students has been influenced by diet orientation, missing meals and eating out etc. In this study, we conducted an accurate condition survey of the total thiamin concentration in the blood among female university students as a means of nutritional assessment and through this we can acknowledge the accurate conditions of the current deficiency conditions and consider the relationship between these deficiency conditions and physical status, food intake conditions and lifestyle habits etc. The participants were 418 female university students aged between 18-20 years old. We conducted the following tests ; anthropometric measurement, a blood examination including total thiamin levels, an investigation into the quantity of food intake according to food group and the quantity of nutritional intake and a survey relating to diet and thiamin. Results showed the average ± standard deviation of total thiamin concentration in the blood was 40.3±9.5 ng/ml and there was almost a normal distribution. The number of individuals who had a lower concentration level of thiamin than 30ng/ml was 58 (approximately 14% of the total). According to the relationship to resident status, the percentage of those living on their own was significantly high among the individuals who had a low level of thiamin concentration. For all of these reasons, it can be surmised that latent thiamin deficiency exists among female university students.
