Hubungan Penggunaan Gadget dengan Kualitas Tidur pada Siswa SMP IT Siti Hajar

Abstract

Background. Excessive use of gadgets among adolescents has been linked to a variety of negative effects, including sleep disturbances. Exposure to blue light emitted from gadget screens can suppress melatonin production and alter circadian rhythms, thereby potentially reducing sleep quality. Adolescents, particularly junior high school students, represent a vulnerable group to these effects due to the high frequency of gadget use for both academic and recreational purposes. Objective. This study aimed to determine the association between duration of gadget use and sleep quality among students of SMP IT Siti Hajar. Methods. This research employed a cross-sectional study design involving a total of 112 eighth-grade students selected using the total sampling technique. Data were collected through a gadget use duration questionnaire and the Pittsburgh Sleep Quality Index (PSQI). Data analysis was conducted using the Chi-square test. Results. The findings indicated that 68.8% of respondents reported moderate gadget use (4–9 hours per day), and 54.5% were categorized as having poor sleep quality. A significant association was found between the duration of gadget use and sleep quality (p < 0.001). Increased duration of gadget use was associated with poorer reported sleep quality. Conclusion. The duration of gadget use was significantly associated with sleep quality among students of SMP IT Siti Hajar.
