Pregnancy in a patient with glycogen storage disease type Ia (von Gierke disease): case report and management strategy.

Caffeine is a natural stimulant that affects the central nervous system. While it is mainly found in coffee beans, it also occurs naturally in some teas and cacao beans and is added to sodas and energy drinks (). Oral caffeine has been licensed by the US Food and Drug Administration (FDA) to help people who are tired or drowsy regain their mental alertness or wakefulness. Additionally, the FDA has authorized intravenous (IV) caffeine for the treatment of preterm apnea (; ; ). Many people, especially young adults, use caffeine to increase alertness and reduce tiredness. Among university students, caffeine use is common because of academic demands and long study hours (). In student populations, sleep problems are also common. Poor sleep quality can reduce daily functioning, impair mood, and increase the risk of depression (). Depression itself is a major concern among students, as it can affect performance, social life, and overall, well-being (). Previous studies have shown links between caffeine use, sleep disturbance, and depressive symptoms. For example, higher caffeine consumption has been associated with poorer sleep and greater psychological distress in student samples (). However, most past research has focused on the amount of caffeine consumed or on simple associations with sleep and mood. Few studies have examined why students consume caffeine, how their motives relate to psychological outcomes, or how different symptoms interconnect. Motivations for caffeine use, such as alertness enhancement, mood regulation, social reasons, weight control, or withdrawal relief, can influence consumption patterns and their effects on mental health (; ). Understanding these motives can help identify high-risk groups and inform targeted strategies for healthier consumption. Caffeine use disorder (CUD) is a condition in which individuals have difficulty controlling their caffeine intake despite negative effects. CUD has been proposed in diagnostic manuals but remains under-studied, especially in young adults (). CUD symptoms have been linked with greater emotional distress and poorer sleep in general population samples (; ). For instance, the development and validation study of caffeine use disorder and caffeine addiction scale found a significant correlation with anxiety, highlighting the importance of considering problematic use patterns when studying caffeine and mental health ().
