Objective: To describe the relationship between mobile phone use and sleep quality among medical students. Methodology: This integrative review was conducted in April 2023 using the BVS and PubMed databases. The descriptors sleep, sleep quality, and medical students were combined with the boolean operator AND. Inclusion criteria comprised original, full-text, free articles published in the last five years, in Portuguese or English. Duplicates and review studies were excluded. The search yielded 2,443 publications; after title and abstract screening, 21 articles were selected, of which 12 composed the final sample. Results: Mobile phone use, particularly at night, was associated with increased sleep latency, reduced sleep duration, and greater sleep inefficiency. Excessive use of the device was also linked to increased consumption of sleep medications, daytime sleepiness, impairment in daily activities, insomnia, and anxiety. These disturbances were more frequent among students classified as smartphone-dependent according to the Smartphone Addiction Scale–Short Version (SAS-SV), which includes ten items rated on a six-point Likert scale, with cutoff scores of 31 for men and 33 for women. Conclusion: Smartphone use has a significant negative impact on sleep quality among medical students.
