Abstract

Introduction: Faculty of Medicine students frequently experience academic pressure and commonly consume coffee to improve alertness. Excessive coffee consumption or consumption at inappropriate times can result in sleep difficulties, disrupt deep sleep stages, and negatively impact the overall quality of nightly rest. Methods: This study investigates the impact of coffee consumption on sleep quality among students. This research employs a cross-sectional design utilizing categorical comparison. Medical students with no history of sleep disorders were included in the study. Data collected include demographic data, Perceived Stress Scale (PSS-10) questionnaire, Pittsburgh Sleep Quality Index (PSQI), and coffee consumption habits questionnaire. Results: Analysis of 96 samples revealed that in the low coffee consumption group, 35 respondents (36.5%) exhibited mild sleep disturbance, while 17 respondents (17.7%) demonstrated moderate-heavy sleep disturbance. In the moderate-high coffee consumption group, 22 respondents (22.9%) presented with mild sleep disturbance, and an equal number showed moderate-heavy sleep disturbance. There were no association between coffee consumption and sleep quality (p =0.131). Conclusions: There were no significant association between coffee consumption and sleep quality in medical students.Keywords: Coffee consumption, sleep quality, medical students

Abstract

Introduction: Carpal Tunnel Syndrome (CTS) is one of the most common entrapment neuropathies, though its exact cause remains unclear.  Obesity has been identified as a potential risk factor, but previous studies have reported inconsistent findings.  This study aimed to analyze the association between Body Mass Index (BMI) and CTS among pre-clinical medical students at Universitas Pelita Harapan. Methods: This cross-sectional study utilized the Boston Carpal Tunnel Syndrome Questionnaire (BCTQ) to assess symptom severity and functional status.  Body weight and height were self-reported via questionnaire to calculate BMI. Bivariate analyses are used to examine the association statistically, followed by stratified analyses to assess potential confounding factors. Results: A total of 201 participants met the inclusion and exclusion criteria for this study. Among them, 7.5% of the subjects presented with symptoms of CTS, and 5.0% experienced functional impairment. The association between BMI and CTS based on the severity of symptoms and functional status impairment was found to be significant (p = 0.004 and 0.049, respectively). Conclusion: Higher BMI was significantly associated with an increased likelihood of CTS symptoms and functional impairment. Gender and a history of diabetes mellitus were identified as potential confounding factors. Keywords: Carpal Tunnel Syndrome, Body Mass Index, Obesity
