This study aimed to examine the relationship between fast food diet and body mass index in vocational students at Universitas Respati, Yogyakarta.

Subjects and Method: This was an analytic observational study with cross-sectional design conducted at Universitas Respati, Yogyakarta. A total of 151 students from batch of 2017-2018 midwifery academy was selected for this study. The dependent variable was Body Mass Index (BMI). The independent variable was fast food consumption. The study subjects were selected by simple random sampling method. Data for dependent variable was measured by weight scale and microtoise. Data for independent variable was collected by Food Frequency Questionnaires (FFQ). The data were analyzed by Spearman rank correlation.

Results: A total of 81 normal-weight female students with an average BMI of 21 kg/ m2 had a habit of consuming 0 to 57 types of fast-food. Frequency of fast-food consumption per week among female students were 0 to 27 times for nine underweight students (BMI <18 kg/m2), o to 31 times for nine overweight students (BMI rang 25 to 30 kg/ m2), 0 to 57 times for eleven obese students (BMI ≥30 kg/ m2). BMI was associated with frequency of fast-food consumption, but it was not statistically significant (p= 0.302).

Conclusion: BMI was associated with frequency of fast-food consumption, but it was not statistically significant.
