Abstract

Introduction: Caffeine is one of the many stimulants found in popular foods and beverages consumed bythe global population. Caffeine has many benefits if it is consumed in accordance with recommended daily doses, such as reducing fatigue and facilitating activity. Caffeine consumption in excess is detrimental to the body, particularly the quality of sleep. Numerous students consume caffeine with the intention of enhancing daytime performance, but they disregard its negative effects, particularly on sleep quality. Methods: This is a cross-sectional study using data collected with the Pittsburgh Sleep Quality Index (PSQI) and a questionnaire for caffeine content based on BPOM for active students at the Faculty of Medicine and Health Sciences, Atma Jaya Catholic University, classes of 2019–2021. The Spearman test was performed to determine the relationship between the independent variable (caffeine intake) and the dependent variable (sleep quality levels). Results: There were forty respondents who satisfied the inclusion criteria. 20% of respondents had good sleep quality, whereas 80% of respondents had poor sleep quality. 60% of respondents consumed low amounts of caffeine or none at all (<32 mg), while 40% consumed high amounts of caffeine (>151mg). The analysis utilizing the Spearman test revealed that some outcomes had no effect (p = 0.876) while others did (r = 0.026). Conclusions: There is no correlation between caffeine consumption and sleep quality among active students at Atma Jaya Catholic University's School of Medicine and Health Sciences.

Abstract

Clean and Healthy Living Behavior (CHLB) is an essential indicator for creating a healthy school environment and preventing environment-related diseases among elementary school children. Preliminary observations at SDIT Masyarul Huda revealed that students' implementation of CHLB indicators was not yet optimal, particularly regarding proper handwashing with soap, personal hygiene practices, and awareness of the importance of maintaining healthy behaviors within the school environment. These findings served as the basis for implementing an interactive educational program aimed at improving students' knowledge of CHLB indicators. This community service program aimed to improve elementary school students' knowledge of Clean and Healthy Living Behavior (CHLB) indicators in the school setting through an interactive educational approach. The program involved 87 students and employed a one-group pretest–posttest design. Students' knowledge was assessed using a pretest–posttest questionnaire administered before and after the intervention. The educational activities consisted of interactive lectures, group discussions, and handwashing demonstrations. Data were analyzed using the Wilcoxon signed-rank test. The results demonstrated that the proportion of students with good knowledge increased from 33.33% during the pretest to 73.56% during the posttest. The normality test indicated that the data were not normally distributed (p < 0.005); therefore, the Wilcoxon signed-rank test was applied, revealing a statistically significant difference between pretest and posttest knowledge scores (p < 0.005). These findings indicate that interactive education effectively improved students' knowledge of CHLB indicators in the school environment. Furthermore, this approach has the potential to serve as a sustainable school-based health promotion model for fostering clean and healthy living behaviors among elementary school students
