The present study was conducted to determine the association between junk food consumption and personal, familial, and social characteristics considering high school students in Rasht, Iran.
Methods: This cross-sectional study was conducted on 341 students in their second year of high school in Rasht, Iran in 2017. They were selected using a two-stage cluster random sampling. Data was collected using a checklist. Data was analyzed in SPSS 16 using Mann-Whitney and Kruskal-Wallis tests at a significance level of 0.05.
