Abstract

Degenerative processes in the central nervous system contribute to in cognitive function decline in the elderly. Physical exercise may prevent this decline. However, elderly people often require modified forms of activity to ensure both safety and effectiveness. This study aimed to investigate the the effect of chair-based exercise (CBE) on cognitive function in elderly people. This study was conducted a two nursing homes using a two-group pretest and posttest experimental design with a control group. All participants were informed about the procedures of study, provided written informed consent, and underwent an initial cognitive assessment using the mini-mental state examination (MMSE). Participants in the intervention group engaged in CBE sessions over a four-week period. Following the intervention, cognitive function was reassessed in both groups. The Wilcoxon signed-rank test was used to analyze within-group changes, while independent t-tests were used to assess between-group differences in cognitive function scores. A significant improvement in cognitive function was observed in the intervention group after the four-week CBE program (p = 0.008). Moreover, a significant between-group difference in cognitive score changes was found (p = 0.003), favoring the intervention group. In conclusion, a four-week CBE program significantly improved cognitive function among elderly participants. These findings support the use of CBE as an accessible and effective intervention to promote cognitive health in elderly people.

Abstract

The rising popularity of K-pop has attracted many teenagers and young adults. Fans tend to purchase idol merchandise as a sign of support and affection, which can lead to compulsive buying behavior. Compulsive buying behavior is one of the coping mechanisms for low self-esteem. This study aimed to investigate the relationship between self-esteem and compulsive buying behavior among undergraduate medical students in Jakarta who are fans of K-pop. A cross-sectional study was conducted involving 97 students, aged 18 to 25, from various medical schools in Jakarta who were actively engaged as members of a K-pop fan club. Data were obtained through the Revised Edwards Compulsive Buying Scale (ECBS-R) and the Rosenberg self-esteem Scale questionnaire. Among the 97 respondents, 35.1% with low self-esteem, and 51.6% with compulsive buying behavior. A significant relationship was found between self-esteem and compulsive buying behavior (p = 0.014). In conclusion, low self-esteem is associated with compulsive buying behavior among K-pop fan medical students, particularly females, which may adversely impact their academic performance.
