Previous research has demonstrated that chronic diseases can occur due to musculoskeletal (MS) pain and poor sleep. It is also worth noting that the caffeine in coffee can reduce overall sleep duration, efficiency, and quality. Thus, the present study examines the effects of frequent coffee drinking (two cups per day) on individuals experiencing MS pain and a lack of sleep during the COVID-19 period. This observational and cross-sectional study recruited 1615 individuals who completed the self-reported (Nordic musculoskeletal) questionnaire. Long-term, frequent coffee drinking and a sleep duration of less than 6 h per day were significantly associated with neck and shoulder pain among healthy individuals. The mediation model demonstrated that the shorter sleep duration and drinking multiple cups of coffee per day had a two-way relationship that worsened such pain over the long term. Specifically, individuals who experienced such pain frequently drank multiple cups of coffee per day, which, in turn, shortened their sleep durations. In summary, long-term coffee drinking creates a vicious cycle between MS pain and sleep duration. Therefore, the amount of coffee should be fewer than two cups per day for individuals who sleep less than 6 h per day or suffer from MS pain, especially neck and shoulder pain.
先前的研究表明，慢性疾病可能由肌肉骨骼（MS）疼痛和睡眠不佳引发。同样值得注意的是，咖啡中的咖啡因会缩短整体睡眠时间、降低睡眠效率并影响睡眠质量。因此，本研究探讨了在新冠疫情期间，频繁喝咖啡（每天两杯）对患有MS疼痛且睡眠不足的个体的影响。这项观察性横断面研究招募了1615名完成了自我报告（北欧肌肉骨骼）问卷的个体。长期频繁喝咖啡以及每天睡眠时间少于6小时与健康个体的颈部和肩部疼痛显著相关。中介模型表明，较短的睡眠时间和每天喝多杯咖啡存在双向关系，从长期来看会加重此类疼痛。具体而言，经常经历此类疼痛的个体每天会喝多杯咖啡，这反过来又缩短了他们的睡眠时间。总之，长期喝咖啡会在MS疼痛和睡眠时间之间形成恶性循环。因此，对于每天睡眠时间少于6小时或患有MS疼痛（尤其是颈部和肩部疼痛）的个体，咖啡摄入量应少于每天两杯。
