Caffeine Consumption among Various University Students in the UAE, Exploring the Frequencies, Different Sources and Reporting Adverse Effects and Withdrawal Symptoms

Assessing well-being of university students and evaluation of its determinants

BACKGROUND

Our study aimed to examine the well-being of students studying at the three (non-medical) faculties of Semmelweis University Budapest, to analyse the relationships between well-being, stress, emotional support, sleep patterns, sport, and further variables like smoking, consumption of sleeping pills, sedatives, psychoactive agents, energy drinks, and exam anxiety.

METHODS

In our cross-sectional study, we asked 561 students of the Semmelweis University of Budapest; two internationally recognised instruments were used: the WHO-5 well-being index and the Perceived Stress Scale.

RESULTS

The mean WHO-5 well-being index was 42.62 ± 20.51 on a scale ranging from 0 to 100. We saw an inverse correlation between student well-being and years of study. The average anxiety level regarding oral exams and assessments was 7.63 ± SD = 2.04, while the mean level was lower concerning written exams and assessments 5.74 ± SD = 2.09. The result of a linear regression model indicates that the best level of explaining power by the regression model was with following variables combination: grade average + anxiety before written exam + academic year + stress.

CONCLUSION

Our data indicate that some students have poor or very poor well-being, which fluctuates over the study period. The worst state was found in the first and final academic year. The students' well-being level is positively correlated with emotional support, physical activity, and quality of sleep and correlates negatively with anxiety before exams. Our results suggest that well-being could be improved when universities play an active role, supporting influential activities and offering help regarding coping with stress, like stress management, as well as by providing information on learning methods and techniques.

Awareness of insomnia caused by coffee consumption among adults in Jazan, Saudi Arabia

The Kingdom of Saudi Arabia is the second largest country in the Arabian Peninsula and ranks 61st out of 150 countries in terms of coffee consumption. Excessive coffee consumption is associated with the risk of adverse health outcomes. This study aimed to assess awareness of the effects of coffee consumption and its relationship with insomnia among the adult population in Jazan, Saudi Arabia. A cross-sectional study was conducted with 431 adults in the Jazan region. A self-administered questionnaire was distributed to the participants using an online survey. Data were analyzed using Statistical Program for the Social Sciences, Version 24.0. Of 431 participants, 377 (87.5%) consumed coffee. Females and married women consumed more coffee than their counterparts (91.3%, P < .01; 92.8%, P < .05; respectively), while students consumed coffee (85.2%) less than both the employed and unemployed (P < .05). The proportion of consumption increased from underweight (79.7%) to normal weight (88.5%), and as high as 91.3% among overweight/obese (P < .05). More than one-third of the participants (35.5%) preferred drinking coffee at coffee shops. The most preferred coffee was Arabic coffee (40%), and the major reason for drinking coffee was to change their mood (29.7%). More than half of the participants (54.5%) reported that coffee caused insomnia (P < .01). Awareness-raising initiatives for the negative effects of excessive coffee consumption are important. Longitudinal studies are required in the next stage of research to identify trends such as the motivations and profiles of Saudi coffee drinkers.

Patterns of caffeine consumption among medical undergraduates in Secunderabad, Telangana, India

BACKGROUND

Caffeine products are increasingly found in a wide range of products that abuse of the substance may be unnoticed. Introduction of new energy drinks has led to an increase in consumption of caffeine in the last few decades. Caffeine is a cognitive booster and has physically enhancing effects, leading to its higher consumption across various age groups. The objective of this study was to determine patterns of caffeine consumption and to determine the knowledge and awareness of side effects and safety limits of caffeine consumption among medical undergraduate students.

MATERIAL AND METHODS

A cross-sectional study was conducted from December 2021 to February 2022 in the Department of Community Medicine at a tertiary care institute, Secunderabad, Telangana, India, among 560 medical undergraduate students of all academic years. A predesigned, pretested, semistructured questionnaire was administered.

RESULTS

The mean age of the study population was 19.09 years, and female preponderance (61.2%) was noted. The average self-reported caffeine consumption was 151.3 mg/day. The average caffeine consumption was found to be higher among males (174 mg/day) as compared to females (137 mg/day). The average consumption of caffeine during exam time was higher than the daily ceiling limit, >300 mg/day, in 38.1% of students, which was statistically significant (P = 0.015).

CONCLUSIONS

Caffeine consumption during times of stress increased among medical students, which is an unfavorable sign as the majority of the times, medical students in future have to deal with physically and emotionally stressful situations during work hours.

Problematic coffee use and associated factors among medical and health science students in Dilla University, Ethiopia

Objective

Coffee holds a cherished place in Ethiopian culture, its consumption among students raises concerns despite its perceived benefits for alertness and productivity. Moderate caffeine intake remains unproblematic, but exceeding 400 mg daily can trigger detrimental health effects such as fatigue, memory impairment, and even attention-deficit disorder. Research on problematic coffee use among young adults, specifically Ethiopian students, remains limited, hindering our understanding of its potential scope and impact. To address this knowledge gap, researchers at Dilla University, Ethiopia, undertook a comprehensive study in 2022, focusing on the university's student population. This investigation holds significant potential to unveil the previously obscured landscape of excessive coffee consumption in this demographic and inform future research and potential interventions.

Methodology

An institutional-based cross-sectional study design was conducted in August-July, 2022. To measure problematic coffee use, this study used the Diagnostic Statistical Manual five criteria for substance use disorder. Those who scored >2 out of 11 criteria were considered to have problematic coffee use. To measure a significant association between the outcome and independent variable, a multivariable logistic regression analysis at p < 0.05 and 95% confidence interval was employed.

Result

This study included 414 respondents. More than half of the respondents, 347 (59.7%) were male. Out of all respondents, 182 (44.0%) had a boy/girlfriend. Nearly half of the respondents, 218 (52.7%) were orthodox, Christian religion followers. According to this study's findings, 137 (33.1%) respondents were considered to have problematic coffee use. Multivariable logistic regression analysis showed that 5-10 years duration of coffee use (AOR = 4.62, 95% CI: 2.96-7.85; p = 0.001), start to use coffee before joining university (AOR = 2.977, 95% CI: 1.332-6.653; p = 0.008) and 6-9 cups of daily coffee use (AOR = 3.26, 95% CI: 2.14-5.89; p = 0.00) were associated with problematic coffee use.

Conclusion

This study showed that one-third of the respondents had problematic coffee use. The starting point, duration, and amount of use had a strong association with problematic coffee use. Hence, focusing on addressing the mental health challenges associated with problematic/excessive coffee consumption among higher education students is advisable. Additionally, promoting awareness of problematic/excessive coffee use and its potential remedies is recommended.

Coffee Consumption Behavior in Young Adults: Exploring Motivations, Frequencies, and Reporting Adverse Effects and Withdrawal Symptoms

Background

Coffee consumption by young people has increased dramatically over the last decades as there are substantial evidence of the physiological, cognitive, and emotional effects of coffee consumption. To reduce the risk of consuming related harm, it is necessary to understand the consumer's motivation for its use.

Objective

This study aimed to investigate coffee consumption behavior in young adults, assess the type of coffee consumption, explore motivation, document adverse effects and withdrawal symptoms of coffee intake.

Methods

A sample of 923 young adults were recruited voluntarily to complete a set of measures examining motivations, adverse effects, and withdrawal symptoms of coffee intake. Logistic regression analysis was performed to determine the association between coffee consumption and all independent variables. A p-value of 0.005 was considered as statistically significant.

Results

The results indicate that more than half of the participants consumed coffee. Coffee consumers were more like to be male, young adults, unmarried, poor sleep pattern (3-5 hours), and smokers. Main motivations of coffee intake were those related to reinforcing effects. The prevalence of dripper coffee consumption (85.59%) was observed to be highest with 20.1% participants consuming coffee in 2-3 times per day. Participants experienced restlessness, shaky, excited, difficulty in falling sleep, and fast heart beat as adverse effects of coffee consumption. Withdrawal symptoms such as headache, mood change, and tiredness were also noticed after consuming a high amount of coffee. Gender (p < 0.005), age (p < 0.003), family income (p < 0.004), BMI (p < 0.002) and sleeping pattern (p < 0.005) were found important variables associated with coffee intake.

Conclusion

The association reported in this study may allow for the implementation of appropriate strategies to address behaviors towards excessive coffee consumption and its link to an increased risk of poor health.

The Indicator of Emotional Eating and Its Effects on Dietary Patterns among Female Students at Qassim University

Emotional eating (EE) is considered as the inclination to eat in response to emotions and is associated with certain syndromes. In this sense, we explored the indices of EE and its association with dietary patterns among female students at Qassim University in Saudi Arabia. A cross-sectional study of 380 participants (aged 18-29 years, female students) was performed. Anthropometric measurements of the participants were taken, such as height, body mass index, fat mass and hip-waist circumference as well as the Emotional Eating Scale (EES). The classification of the ESS included the thresholds of 44.7, 43.9 and 11.3% for low, moderate and high EE, respectively. Linear regression after adjustment showed that fat intake was a significant predictor of EE (p = 0.031) as well as feelings of enthusiasm. We also observed an interesting indication: fat intake (p = 0.011) and educational level (p < 0.05) were significantly associated with, and could be significant predictors of, EE. The results highlight the importance of emotional eating, its relationship with the consumption of foods that contain fat and understanding how it develops by raising awareness of the importance of healthy food for a healthy lifestyle.

Assessment of caffeine consumption behavior among Jazan University students in the south of Saudi Arabia: A cross-sectional study

Caffeine is a central nervous system stimulant. High consumption levels of caffeine can lead to intoxication and serious side effects. Saudi Arabia is witnessing a rise in the commercialization and consumption of caffeine. Young adults such as university students may exhibit high levels of caffeine consumption. This investigation aims to assess caffeine consumption habits among a sample of Jazan University students in the south of Saudi Arabia. This study was a cross-sectional investigation that utilized multistage sampling to recruit the students. Data was collected via a self-administered questionnaire that measured student demographics, their frequency of consuming caffeine-containing food, portion sizes, and patterns of consumption during different times of the day. Caffeine consumption levels were estimated based on a cutoff point of 400 mg per day. A chi-squared test was used to investigate the association between levels of caffeine consumption and measured study characteristics. A sample of 964 students was recruited with a mean age of 21.8 years. The most frequently consumed product among the recruited students was coffee (32%), followed by chocolate bars (16%) and soft drinks (12%). The median total consumed caffeine amount was 185 mg per day. 194 (20%) students of the sample exceeded the recommended level of daily caffeine consumption (>400 mg/day). Among the measured demographics, only the year of study was associated with caffeine consumption (P value of .003), suggesting that students in their earlier years of university are likely to exceed the recommended daily consumption of caffeine in comparison with those who are in their later years of study. Our investigation identified high levels of caffeine consumption among some students. The findings imply the need to enhance the awareness of students who exceed the recommended daily intake of caffeine regarding the harmful impacts of caffeine toxicity.

Fermented Black Tea and Its Relationship with Gut Microbiota and Obesity: A Mini Review

Fermentation is one of the world’s oldest techniques for food preservation, nutrient enhancement, and alcohol manufacturing. During fermentation, carbohydrates such as glucose and starch are converted into other molecules, such as alcohol and acid, anaerobically through enzymatic action while generating energy for the microorganism or cells involved. Black tea is among the most popular fermented beverages; it is made from the dried tea leaves of the evergreen shrub plant known as Camellia sinensis. The adequate consumption of black tea is beneficial to health as it contains high levels of flavanols, also known as catechins, which act as effective antioxidants and are responsible for protecting the body against the development of illnesses, such as inflammation, diabetes, hypertension, cancer, and obesity. The prevalence of obesity is a severe public health concern associated with the incidence of various serious diseases and is now increasing, including in Malaysia. Advances in ‘omic’ research have allowed researchers to identify the pivotal role of the gut microbiota in the development of obesity. This review explores fermented black tea and its correlation with the regulation of the gut microbiota and obesity.
