Assessment of Impacts of Mobile Phone Usage on Sleep Quality and Concentration Among Undergraduate Students of Crescent University, Abeokuta
Mobile Phone Usage on Sleep Quality and Concentration
Abstract
In recent years, mobile phone usage among undergraduates has reached unprecedented levels, raising serious health and academic concerns. This study assessed the impact of mobile phone usage on sleep quality and concentration among undergraduate students of Crescent University, Abeokuta. A descriptive cross-sectional study was used to assess this study. The study population consists of 2,202 undergraduate students. Multistage sampling technique, Taro Yamane (1967) Formula, Finite Population Correction (FPC), and Undergraduate Resource-Constraint Adjustment Rule (50–60% of Yamane) were used to select 180 respondents. A validated and self-developed structured questionnaire was constructed to elicit information on research-specific objectives, and the distributed questionnaire was analyzed using SPSS 26.0 version. The result showed that, among 180 undergraduate students, most were females (61.1%), aged 20–23 years (43.3%), in Nursing (50.0%), and at the 200 level (29.4%). Sleep quality was high in 26.7%, moderate in 42.2%, and low in 31.1%. All (100%) owned smartphones, mainly Android (52.7%). Primary use was social media (70.6%), followed by assignments (57.2% always), educational clips (42.2% always), and phone use during lectures/tutorials (26.7% sometimes). The study concluded that about 120(66.7%) of the students have a high level of concentration during academic activities in relation to mobile phone usage, while 60(33.3%) have a low level of concentration respectively. The study recommended that parents and school administrators should urge students to limit social media screen time, activate Do Not Disturb mode/app blockers during classes, and enforce phone-free hours before bed to enhance concentration and sleep quality.
