Abstract

Background: A smartphone is a device that is widely used by various groups, one of which is college students. The use of smartphones by college students can be seen from their needs in the learning process. Smartphones are one of the most significant sources of electromagnetic waves that, if used excessively, might affect eye health. Eye strain is a complaint to the eyes that generally occur due to excessive smartphone use. Objective: This study aimed to examine the relationship between the duration of smartphone use and undergraduate students’ eye strain risk. Methods: This study was a cross-sectional analytical observational study between September 2022 and December 2022. The 104 students in the Physiotherapy Study Program at Faculty of Medicine, Universitas Udayana, who ranged in age from 20 to 23, were the study's participants. Total sampling was used as a non-probability sampling technique. Results: The results of the study found that 16 people (15.4%) had an excellent smartphone usage duration of ≤ 4 hours and 88 people (84.6%) had a lousy smartphone usage duration of > 4 hours. The results of the Spearman Rho non-parametric analysis test showed a relationship between the time of smartphone use and eye strain complaints in students (p= 0.001) with a positive coefficient (r= 0.328). Conclusion: There was a significant relationship between the duration of smartphone use and undergraduate students’ eye strain risk.

Abstract

Background: The elderly are individuals who experience a slow ageing process that can cause a decrease in physical function and condition. A noticeable decrease in function in the elderly is a decrease in muscle mass. This study aimed to determine the relationship between leg muscle strength and functional mobility ability in the elderly. This study aimed to determine the relationship between leg muscle strength and functional mobility in the elderly. Methods: The design of this study was observational analytic with a cross-sectional study direction. At the research site at Puskesmas II Tabanan, the number of research subjects was 63 older people aged 60-69 years. A 30-second chair stand test measures leg muscle strength, while a timed up-and-go test measures functional mobility ability. Results: The results of the association test using Spearman's Rho Test obtained a correlation coefficient value (r) -0.535 with a p-value=0.000 (p<0.05), which means there is a strong significant relationship that is negative in both variables. Conclusion: There was a strong negative significant relationship between leg muscle strength and functional mobility ability in the elderly at Puskesmas II Tabanan.
