Background: Over the past decade, the global caffeine consumption rate has increased dramatically. Coffee and tea are among the common sources, but energy drinks are becoming an important contributor to total caffeine consumption. Recommendations for daily caffeine intake is not being followed due to the perceived benefits of caffeine which include mood improvement, concentration, social factors, and energy boosting. This study was important to add to the limited data about caffeine consumption in the Gulf region and mainly in the UAE.Objectives: The objectives were to determine the prevalence of caffeinated beverage consumption among university students and perceived benefits in addition to the estimation of daily caffeine consumption (mg/day).Design: Data was collected through a self-reported questionnaire from a total of 175 participants (129 females and 46 males) who were conveniently selected from different settings at Zayed University - Dubai. Usual Caffeine intake was calculated from all caffeine containing beverages.  Results: Eighty-six percent of the 175 participants, both males and females, at Zayed University-Dubai consumed caffeinated beverages with an average intake of 249.7±235.9 mg. The intake among the 150 caffeine consumers varied from 4.2 mg/day to 932.2 mg/day. Average intake of caffeine was not significantly different between genders (P=0.125). Thirty-five percent of the population consumed more than 400 mg/day of caffeine, with no statistical difference between males and females (P=0.202). Coffee was the most commonly consumed drink among both genders, followed by tea. Most perceived benefits of caffeine consumption were not significantly different except for the relationship between caffeine and improved exercise performance (P=0.018) and caffeine in relation to weight loss (P=0.001) among males.Conclusion: The prevalence of caffeine consumption at Zayed University was high among both males and females. Further research is necessary to estimate the total caffeine intake from all dietary sources, mainly the cultural foods and beverages, and to determine the relationship between accessibility to caffeine containing beverages and caffeine consumption among University student.

Abstract Objectives Caffeine is a widely consumed stimulant on the beverage market. It is known to affect the autonomic nervous system (ANS), influencing the balance of parasympathetic versus sympathetic drive. This can be measured by heart rate variability (HRV) – fine scale changes in normal sinus rhythm. However, there has been little research done regarding the influence caffeinated drinks have on HRV in active university students. The purpose of this observational study is to examine the relationship between habitual caffeine intake and morning HRV readings in this population. It is hypothesized that higher intakes of caffeine will be associated with lower, more sympathetic HRV scores. Methods Healthy participants (N = 24, 18–25y) were drawn from two related investigations. Subjects were free of stimulant medications and recreationally active, but not part of an organized sports team. Subjects were given a daily diet log over 3–4 d to record food and drink intake, which was analyzed for caffeine (mg) using the Food Processor software (ESHA Research, Salem OR). Simultaneously, daily fasted HRV (100-scale composite score) was observed with a Holter-type sensor and software (ithlete, Southampton, UK) shortly after waking. Results Average caffeine intake did not significantly correlate with average HRV (r = 0.269; P = 0.204). Comparisons of caffeine intake with individual-day HRV measures were similarly weakly positive and non-significant with the exception of the final day of recording, which was more robust (r = 0.543; P = 0.036). Conclusions The data failed to support our hypothesis that habitual intakes of caffeine would be negatively associated with early morning, fasted HRV scores. Habitual caffeine consumption was not a significant contributor to sub-chronic sympathetic drive. Rather, the relationship tended to be positive (greater vagal tone), not negative (a more “stressed” ANS) as predicted. Future research should investigate the acute and chronic effects of specific caffeine sources on specific catecholamines and their relationship to HRV in young, physically active populations.

Purpose: To examine the sleep of rugby league athletes the night before and following an evening match and to investigate the association between caffeine intake and sleep on the night of competition. Methods: On the night prior to, night of, and night after a professional rugby league match, 15 athletes had their sleep monitored using wrist activity monitors. Additionally, saliva samples were collected 60 minutes before and 30 minutes after the competition to assess salivary caffeine concentration. Differences in sleep across the 3 nights were examined using linear mixed models, and changes were assessed using effect size (ES). Pearson correlation (r) assessed the relationship between salivary caffeine levels and sleep indices. Results: On the night of competition, athletes went to bed later than the night before (P = .00002, ES = 1.84) and night after (P = .0003, ES = 1.49) competition. Consequently, their sleep duration was reduced on the night of competition compared with the previous night (P < .0000003, ES = 2.36) and night after competition (P = .001, ES = 1.53). Postcompetition salivary caffeine concentration was substantially elevated in athletes when compared with precompetition measures (P < .00000001, ES = 4.44), and moderate, nonsignificant correlations were observed between changes in salivary caffeine concentration and delayed bedtime (r = .48, P = .07), increased sleep latency (r = .45, P = .09), decreased sleep duration (r = −.30, P = .28), and reduced sleep efficiency (r = −.34, P = .22). Conclusions: These results demonstrate that evening competition results in sleep disturbance in rugby league athletes, and caffeine supplementation prior to and during competition leads to substantial increases in postcompetition salivary caffeine concentration.

This study aimed to assess the caffeine consumption of Saudi Arabian undergraduate students and to determine if the average amount consumed is within healthful parameters. Caffeine consumption in Saudi Arabia is a major cultural and social feature. Consumption of excessive amounts of caffeine can be deleterious to the health of university students. This is a cross-sectional study. A total of 145 male undergraduate nursing students were surveyed using the Caffeine Consumption Questionnaire to assess their caffeine intake on a typical day. Among this group, 34.5% of students exceeded the 400mg daily safe levels for caffeine consumption. The average consumption of the total group, those consuming below 400mg and those exceeding 400mg were 325.1, 201.2, and 570.1 mg, respectively. Tea and coffee were the major contributors to total caffeine intake ranging from 0-8 (240ml) servings per day. Health promotion aimed at illuminating health risks of caffeine consumption exceeding safe limits may assist in modification of intake to more healthful levels.

BACKGROUND: Caffeine can affect depressive symptoms and decision-making. OBJECTIVE: This study aims to examine the relationship between caffeinated beverages consumption with depressive symptoms and decision-making styles. METHODS: This cross-sectional study was conducted with 432 adults working in office environment. The questionnaire consisting of individuals’ socio-demographic attributes, the frequency and the amount of caffeinated beverages consumption, the “Epidemiological Research Center-Depression (CES-D) Scale” and the “Decision-Making Styles Scale” were used. The frequency and amount of caffeinated beverages were determined using the food frequency questionnaire (FFQ). The participants were asked to choose which cup/mug they prefer to drink their caffeinated beverages and what amount they consume that beverage at a time. All the data were collected using online platforms. RESULTS: In the study, 76.7%of the participants were female and the mean age was 31.5±8.0 years. The average daily total caffeine intake of the participants was 425.8±461.4 mg and the total CES-D scale score was 17.7±11.2 points. It was found that as the amount of caffeine consumed increased, intuitive decision-making decreased and depressive symptoms increased (p <  0.05). In linear regression analysis, total caffeine consumption was found to be a significant predictor for the intuitive decision-making score (B: –0.151; p:0.002). When caffeine consumption is controlled, intuitive and rational decision making decreases with increasing depressive symptoms while addiction and avoidance decision making increased (p <  0.05). CONCLUSIONS: As a result, the amount of caffeine consumed daily was related to intuitive decision-making but did not effect depression. It has been observed that depressive symptoms affect decision-making styles in different ways. To our knowledge, our study is the first to examine the effects of caffeine consumption on depression and decision-making styles. Accordingly, future studies may focus on the link between caffeine consumption, depression, and decision-making styles in larger populations and the mechanisms that influence this relationship.

Abstract Introduction Excessive caffeine intake has been thought to be a contributory factor for tinnitus. However, there has been no systematic review to elucidate the causal relationship between caffeine intake and the incidence of tinnitus. Objectives We performed the current review aiming at evaluating the evidence from the current literature for the relationship between caffeine intake and the incidence of tinnitus. Data Synthesis Databases including PubMed, Scopus, and Google scholar were searched for relevant articles. A total of 142 studies were screened for eligibility, of which four articles met our inclusion criteria: two were prospective cohorts and two were cross-sectional studies. Although one study found no association between caffeine consumption and the incidence of tinnitus, an inverse relationship was reported by two population-based studies. Concerning patients with preexisting tinnitus, reduction of caffeine intake in a subset who consumed 150 ml to 300 ml/day of coffee yielded a favorable outcome in tinnitus severity. However, those with higher dose intake were less prone to have improvement in the severity of tinnitus. Conclusion Although the current review was inconclusive, it appears that the incidence of tinnitus in previously unaffected individuals might be prevented by a high dose of caffeine intake. However, in preexisting tinnitus, a high dose of caffeine may adversely interfere with the efficacy of caffeine reduction.

AbstractThe WHO reported that high blood pressure (BP) is one of the primary causes of death worldwide. Hypertension (HPT) is a major risk factor for CVD and related diseases as well as for diseases, leading to a considerable increase in cardiovascular risk. Since BP response could also be influenced by caffeine, which is widely consumed with coffee and other items, it is important to define the possible effects associated with caffeine intake. The most recent findings aimed at clarifying the role of caffeine consumption on BP and HPT risk/incidence are conflicting and difficult to interpret. Therefore, in the present narrative review, we aimed to examine various methodological inaccuracies/aspects and factors that make studies difficult to be compared, in order to obtain a single consensus on the effects of caffeine intake on the risk of BP and HPT. We observed that this heterogeneity in results could be due to the presence of: (i) several variables affecting BP (such as age, sex, genetic and lifestyle aspects); (ii) different caffeine content of food and beverages; and (iii) caffeine metabolism. Moreover, different methodological aspects in the evaluation of daily dietary caffeine intake and in the BP measurement could add some other bias in the interpretation of results. Therefore, it is mandatory to consider all methodological aspects and confounding factors to generate a standardised methodology in order to increase cross-study consistency and minimise confounding effects of different variables on the relationship between BP response and HPT risk/incidence after caffeine intake.

"The commercial developments lining the coasts of the Arabian Peninsula that have emerged within the past decade have various implications for the environment, economy, and society as a whole. In particular, this paper is interested in the relationship between residents’ perceptions of the coastal landscapes that are being created and the effects of such extensive developments, including their demands on water. Less than 50 years ago, this arid region consisted of a few tribes who collected water from nearby wells and springs. After the rise of the oil industry in the 1970s, however, the United Arab Emirates’ growing population and burgeoning economy introduced desalination plants to sustain the people and irrigate lush landscapes, which require significant amounts of energy and infrastructure. Located in Ras Al Khaimah, Al Jazeera Al Hamra is one of the only full standing abandoned villages in the Gulf region and carries a rich history and once critical coastal location. This paper will profile the village as a prototype for coastal developments in arid environments. Inspired by the traditional practices of the region’s inhabitants, this paper introduces a design model that integrates several factors. These include the types of visual references represented in the Gulf region, people’s contemporary lifestyles, water saving techniques, and the effects of these proposals on the surrounding environment."

Objective: Caffeine has been considered a trigger for atrial fibrillation (AF). We conducted a meta-analysis including a dose-response analysis to assess the relationship between caffeine consumed and incidence of AF. Methods: Data from selected studies represented 176,675 subjects (AF in 9,987 [5.7%]). Caffeine content varied widely, ranging from 40 to 180 mg per cup of coffee. For purposes of the calculations in this study, we assumed 140 mg of caffeine in a standard 12-oz cup of coffee. Results: No significant difference was found in AF incidence when the subjects consuming less than 2 cups of coffee per day were compared to subjects with higher consumption, 1.068 (0.937–1.216). The risk of AF was higher among subjects consuming less than 2 cups of coffee daily when compared to higher daily consumption subjects. A lower incidence of AF was found among people consuming more than 436 mg daily. Conclusion: The incidence of AF is not increased by coffee consumption. In fact, we found a lower incidence of AF when caffeine consumption exceeded 436 mg/day. Therefore, based on available evidence there is no association between caffeine intake and AF risk.

Museums and cultural developments are on the rise in the Gulf region. The United Arab Emirates is home to some of the most ambitious and extravagant museum projects in the world. In this article, I consider the example of the Louvre Abu Dhabi, exploring some of its underlying dynamics and context. I focus mainly on the relationship between branding and legitimation while placing my analysis within a wider critical debate, which includes discussions on the link between museums and identity, the legitimizing role of architecture, and the various contentious concerns and controversies surrounding the Louvre Abu Dhabi project. I conclude that the United Arab Emirates and other neighbouring countries have an excellent opportunity for innovation in the cultural field if they are willing to critically and ethically found their cultural developments on an ethos of inclusivity, openness, experimentation, non-exploitation and curatorial courage.
