Sampling was done as a simple stratified method. Data were collected by a researcher made questionnaire and were analyzed with SPSS software.The mean age of participants was 16.2±0.9. Average of tuition and math score were 17.3±1.8 and 15.6±3.8. 72.6% of students take breakfast every day and only 2.1% went to school without it. 64.6% ate snack every day. There was no correlation between taking of breakfast with the level of attention in class and tuition, but the math score was correlated with breakfast (p=0.045, r=0.107). There wasn’t any association between math scores and level of attention with consumption of snacks (p>0.05). There is a significant relationship between taking of breakfast with BMI (p<0.001, [CI:0.001-0.010]). Eating breakfast can have a positive impact on scores of subjects, especially math score. It is essential to perform studies with control groups to achieve more accurate results. https://biomedpharmajournal.org/vol6no2/association-between-breakfast-consumption-and-math-scores-of-high-school-students-in-tehran/ Breakfast Snack Math score Body mass index Student
