Abstract
Introduction:
Caffeine is widely used as a cognitive, physical, and psychomotor booster. Recent studies have suggested worrying trends of overconsumption of caffeine, accompanied by higher risk for multiple diseases, including diabetes mellitus type 2. There's a general lack of research in the middle east regarding caffeine consumption patterns. The aim of this study is to assess caffeine consumption levels among the United Arab Emirates (UAE) adult population, as well as the population general knowledge and attitude regarding its health implications.
Methods:
A cross-sectional study was conducted from July to August 2016 on 403 randomly chosen people from five emirates in the UAE. Self-administered questionnaires were distributed through a nonprobability sampling method. The number of participants selected from each emirate was proportionate to the population size of each city.
Results:
The mean total caffeine consumed per day was 316.7 mg, close to the acceptable daily intake of 400 mg/day. More than 98.5% of the study participants were caffeine consumers, with 31% reported being addicted to caffeine. Caffeine consumption was significantly associated with smoking and people with heart problems. The mean level of knowledge about caffeine was less than 33%. Younger participants (p = 0.008) and those who work in healthcare & education (p < 0.001) were significantly more knowledgeable.
Conclusion:
Caffeine consumption is very prevalent among UAE population, which ranks high among other countries. There is a lack of accurate knowledge regarding the effects of caffeine on health and well-being. Healthy consumption behaviors need to be promoted through a better awareness and transparent environment.
