Introduction : Sleep quality is an important component in supporting the growth and
development of school-age children, while increasing the intensity of gadget use in this age
group has the potential to disrupt rest patterns and reduce sleep quality. This study aims to
analyze the relationship between the intensity of gadget use and the sleep quality of school
age children in SD Negeri 5 Manistutu. Methods: This study used a correlational descriptive
design with a cross-sectional approach and involved 69 respondents through a total sampling
technique. The research instruments used were a questionnaire on the intensity of gadget use
and the Pittsburgh Sleep Quality Index (PSQI). Relationship analysis was carried out using the
Chi-Square test. Results: The results showed that most children had a high intensity of gadget
use (69.6%) and poor sleep quality (94.2%). The Chi-Square test showed a significance value
of p < 0.001 which indicates a meaningful relationship between the intensity of gadget use and
the sleep quality of school-age children, with the distribution of data showing that children
with medium and high gadget use were all in the category of poor sleep quality. Discussion :
These results indicate that the higher the intensity of gadget use, the more likely the child is to
experience poor sleep quality. These findings can be the basis for educational efforts and
regulations on the use of healthier gadgets for school-age children.
