Caffeine Consumption and Its Potential Health Effects on Saudi Adolescents in Jazan

Background Caffeine is the most popular product consumed globally in different types and amounts by various age groups. This study aimed to identify caffeine consumption patterns among adolescents in Jazan and explore related health effects. Methodology A cross-sectional study was conducted in Jazan on adolescents between 12 and 18 years of age. The consumption of coffee and caffeinated products and their potential health effects were evaluated using a self-reported online questionnaire. The data were analyzed using software for descriptive and inferential statistics. Results A total of 718 participants were enrolled in this study, with the age group of 16-18 years constituting the highest percentage (48.9%). Nearly 94% of the participants consumed coffee or caffeinated products, with 57% consuming the products infrequently. About 6.6% consumed coffee or caffeinated products more than three times daily, and about half of the participants used medium-sized cups. The most consumed type of caffeinated beverage was Arabic coffee, followed by tea, soft drinks, and Nescafe. Education level and age group showed a significant correlation with consumption patterns. The most common health effects of caffeine consumption were headaches, irregular sleep, and nausea, which were statistically related to age group, gender, and comorbid conditions. Conclusions Consumption of coffee and caffeinated beverages was relatively high among adolescents in this study. Further research on the habits of Saudi adolescent consumers, particularly across different areas of the country, is required.
