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.
