To examine the relationships between Ramadan fasting observance (RFO) and sleep-wake patterns, daytime sleepiness, and insomnia levels in student-athletes.
Sleep was measured using wrist-actigraphy in 25 semi-professional student-athletes (mean ± SD; age = 22 ± 2 years, height = 182.0 ± 5.8 cm, body mass = 81.3 ± 15.2 kg) during seven nights before RFO (academic study period), during the first half of RFO (14 nights, holiday period), and the second half of RFO (14 nights, academic study period). Additionally, participants completed the Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI) questionnaires seven days before RFO and on the last day of RFO.
Actigraphy results indicated RFO was associated with significant decreases in sleep duration during the second half of RFO vs. before and during the first half of RFO (p < 0.001). However, the first half of RFO was associated with a delay of ⁓ 2.5 h in sleep onset compared to before RFO; this delay persisted during the second half of RFO (p < 0.001). The total PSQI score before RFO (6.6 ± 2.3 AU) and during RFO (8.2 ± 2.3 AU) suggested poor overall sleep quality. ISI and ESS scores were greater during than before RFO (p = 0.002 and p = 0.041, respectively).
The second half of RFO was associated with decreases in objectively assessed sleep duration among student-athletes. RFO was also associated with impaired sleep quality, excessive daytime sleepiness, and increased insomnia symptoms. Personalized interventions to address sleep-related issues in student-athletes during RFO are warranted.
研究斋月封斋（RFO）与学生运动员的睡眠-觉醒模式、日间嗜睡和失眠水平之间的关系。
在 RFO 前（学术研究期）、RFO 前半段（14 晚，假期）和 RFO 后半段（14 晚，学术研究期）的七个晚上，使用腕动仪测量 25 名半职业学生运动员（平均±标准差；年龄 22±2 岁，身高 182.0±5.8cm，体重 81.3±15.2kg）的睡眠情况。此外，参与者在 RFO 前七天和 RFO 最后一天完成了 Epworth 嗜睡量表（ESS）、失眠严重程度指数（ISI）和匹兹堡睡眠质量指数（PSQI）问卷。
腕动仪结果表明，RFO 与 RFO 后半段的睡眠时间明显减少有关，与 RFO 前半段和 RFO 前相比（p<0.001）。然而，RFO 前半段与 RFO 前相比，入睡时间延迟了 ⁓ 2.5 小时；这种延迟在 RFO 后半段仍持续存在（p<0.001）。RFO 前（6.6±2.3 AU）和 RFO 期间（8.2±2.3 AU）的总 PSQI 评分表明整体睡眠质量较差。ISI 和 ESS 评分在 RFO 期间高于 RFO 前（p=0.002 和 p=0.041）。
RFO 后半段与学生运动员客观评估的睡眠时间减少有关。RFO 还与睡眠质量受损、日间嗜睡增加和失眠症状加重有关。在 RFO 期间，有必要针对学生运动员的睡眠相关问题进行个性化干预。
