Nutritional health requires nutritional literacy. In order to increase it, appropriate educational programs are needed. Therefore,this study was conducted to determine the effect of nutrition on nutritional literacy and body mass index (BMI).

In this analytical study, 228 medical students were selected and then divided into two groups that had passed the nutrition unit (n =114) and the group that had not yet passed this course unit (n = 114). Data collection tools included Personal information,nutrition literacy questionnaire and BMI calculation.The date were analyzed by SPSS version 19 for analyzing the data, descriptive(frequency, mean and standard deviation) and inferential (Chi-square, IndependentT,one-way ANOVA, Pearson and Binary logistic regression) statistical methods were used.

There was no significant difference between BMI classification and the nutritional literacy mean between the two groups. There was a significant difference between the levels of nutrition literacy (low, medium, high) in the two groups (p value = 0.015). There was no significant relationship between BMI score with passing the nutrition course and nutrition literacy score in both groups. Also, binary logistic regression test showed that passing the nutrition course, could increase nutrition literacy by 0.52 times in students who passed the course than who did not (p value = 0.02).

The findings of this study showed a higher level of nutrition literacy in students who had passed the nutrition course. Therefore, it may be possible to increase nutrition literacy and promote nutritional health by emphasizing more on the mentioned academic unit.

This study aimed to assess the relationship between nutrition literacy and diet with obesity. Obesity is believed to be the most common health problem worldwide. This was a cross-sectional study. The population included 20-30 years old women and men in Tabriz, Iran. The data collected on nutrition literacy, diet and obesity as appropriate. Then, the relationship between dependent variable (obesity) and independent variables including nutrition literacy and diet was examined using logistic regression analysis. A sample of 400 individual participated in the study. The findings indicated that the prevalence of obesity among women was 72.2% and in men it was 27.8%. The diet had an inverse relationship with obesity and nutritional literacy was directly related to obesity. Also, the results obtained from logistic regression analysis showed that nutrition literacy and diet can significantly predict the obesity. These variables explained 52% of the variance of dependent variable (obesity). The findings confirmed that healthy lifestyle, especially appropriate diet could play an important role in preventing obesity and its consequences.
