Data on the relationship between caffeine addiction and stress among Lebanese medical students in Lebanon

Abstract

Stress continues to be a global burden. It may be thought of as necessary to human thriving; however, challenging and unfavorable functioning may take place when many significant stressors are imposed repetitively or concurrently without resolve. Research suggests that medical students perceive higher levels of stress than students in other health-related disciplines [1–3]. Since caffeine is a psychoactive substance that stimulates the central nervous system, medical students use to consume it more than other students to overcome the stress they face due to studying. The paucity of knowledge regarding the trends of caffeine consumption among medical students in developed countries and especially in Lebanon has encouraged us to examine the relationship between caffeine addiction and stress among Lebanese medical students in Lebanon. A non-experimental cross-sectional correlational design was employed to gather data from a sample of 800 medical students enrolled in different studying years in different Lebanese universities. Well-established psychometric instruments were used in primary data collection method, which are the Medical Student Stressor Questionnaire (MSSQ) and the Caffeine Consumption and Dependence Scale. The analyzed data is provided in the tables included in this article.

Caffeine improves work durability and physical performance in anaerobic exercises among active adults in Tripoli Lebanon

“…Caffeine consumption was popular among our study sample, with 92.2% indicating that they use a certain caffeinated product, most commonly coffee, soft drinks, and tea. This data is homogeneous with a study done on different university students in Lebanon indicating that 97% of 800 students use caffeine products [4]. Despite the literature showing a positive association between caffeine consumption and both aerobic and anaerobic activities [2], our results showed the absence of signi cant association between aerobic exercises and the three factors for the caffeine consumption variable: (1) caffeine as a physical performance enhancer, (2) caffeine as work durability enhancer and (3) caffeine as a productivity enhancer.…”

“…Our ndings are convergent with a double-blind, placebo-controlled randomized cross over study on anaerobic activities. Madden et al revealed that perceived effort is greater in the caffeine group compared to the placebo [9] suggesting that caffeine could increase overall physical performance in anaerobic activities. Moreover, McDaniel et al (2010) showed a 4.2 seconds enhancement in anaerobic activities in the caffeine group compared to placebo [2].…”

“…In addition, our data on caffeine consumption and exercise (aerobic and anaerobic) were collected based on past exposure and thus our ndings could be affected by recall bias. This type of bias may underestimate the measure of association and reduce the probability of nding a signi cant association [9].…”

“…Kacza et al (2020) have demonstrated that supplements including caffeine have a positive effect on anaerobic activities, especially in delaying fatigue and increasing strength [8]. Madden et al (2019) also found that the rating of perceived exertion and physical performance was higher in the group of individuals ingesting caffeine [9]. McDaniel et al's (2010) theory suggested that caffeine consumption had a direct effect on the central nervous system by increasing alertness and decreasing fatigue [2].…”

“…McDaniel et al (2010) have found that caffeine consumption increases productivity while performing aerobic and anaerobic exercises [2]. Yet, it had no effect on reducing fatigue after soccer game [11], while physical performance is only improved after caffeine consumption when performing anaerobic activities [2,9].…”
