Use of social networks and sleep quality in students of basic sciences of human medicine in Cajamarca - Peru 2025

Social networks also affect different aspects, such as sleep quality, which is key to the learning process. Objective: To test the extent to which there is a relationship between sleep quality and the use of social networks among undergraduate students of human medicine at a public university in Cajamarca. Materials and methods: A quantitative, correlational, cross-sectional analysis study was conducted with 150 students (65 women and 85 men). The study used the Pittsburgh Sleep Quality Index (PSQI), which consists of nine scores on a scale of 0 to 3, with the lowest score indicating the best and the highest score indicating the worst. The total score is obtained by summing the individual scores, with higher scores indicating poorer sleep quality, with a Cronbach's alpha of 0.83. The questionnaire developed by Camahuali to measure the extent of social network use consisted of 20 Likert scale questions, with a Cronbach's coefficient of 0.81. Results: 62% of students used social media moderately and 82% had poor sleep quality. The correlation between the two variables was almost zero, but a possible relationship cannot be excluded. Conclusion: Although statistical significance was not reached, a correlation was observed between sleep quality and social media use.
