<![CDATA[This study sought to investigate the correlation between sleep quality and the frequency of junk food consumption with body mass index (BMI) among medical students at Universitas Muhammadiyah Yogyakarta (UMY). A quantitative cross-sectional study was executed via purposive sampling of medical students from the 2020–2022 cohorts. An online questionnaire was used to collect data on the respondents' characteristics, their self-reported weight and height (to calculate BMI), their sleep quality (using the Pittsburgh Sleep Quality Index), and how often they ate junk food (using a food frequency questionnaire). Separate correlation studies were conducted for men and women. There was no significant link between sleep quality and BMI in either males (p=0.502) or women (p=0.118). The frequency of junk food consumption did not show a significant correlation with BMI in women (p=0.292). For men, the frequency of junk food consumption had a strong positive link with BMI (r=0.490, p=0.008). In conclusion, sleep quality did not connect with BMI in either gender; nevertheless, increased junk food consumption was linked to a higher BMI exclusively among male students.]]>
