To examine the proportion of participants with poor sleep quality, evaluate the associations between sleep quality and anthropometric and cardiometabolic health markers, and evaluate the effect of high intensity interval training (HIIT) and continuous aerobic exercise training (CAET) on sleep quality in polycystic ovary syndrome (PCOS).
Secondary analysis of a pilot randomized controlled trial.
Women with PCOS aged 18-40 years.
The Pittsburgh Sleep Quality Index (PSQI) was measured at baseline and following a 6-month exercise intervention. A PSQI score >5 indicates poor sleep. Linear regression was used to evaluate the associations between PSQI score and anthropometric and cardiometabolic health markers, and the effect of exercise training on these associations.
Thirty-four participants completed the PSQI at baseline, and 29 postintervention: no-exercise control (n = 9), HIIT (n = 12) and CAET (n = 8). At baseline, 79% had poor sleep quality. Baseline PSQI score was positively correlated with body mass index, waist circumference, body weight, haemoglobin A1c and insulin resistance. Mean PSQI score changes were -0.4 (SD 1.1), -0.7 (SD 0.6) and -0.5 (SD 0.9) for control, HIIT and CAET, respectively. For HIIT participants, change in PSQI score was associated with changes in body weight (B = .27, 95% CI 0.10-0.45) and waist circumference (B = .09, 95% CI 0.02-0.17).
Most participants had poor sleep quality which was associated with poorer anthropometric and cardiometabolic health markers. There were no statistically significant changes in PSQI score with exercise training. With HIIT training, decreases in the sleep efficiency score were associated with reductions in body weight and waist circumference. Further studies are needed to determine the effect of exercise training on sleep quality.
研究睡眠质量差的参与者比例，评估睡眠质量与人体测量指标及心脏代谢健康标志物之间的关联，并评估高强度间歇训练（HIIT）和持续有氧运动训练（CAET）对多囊卵巢综合征（PCOS）患者睡眠质量的影响。
一项试点随机对照试验的二次分析。
年龄在18 - 40岁的PCOS女性。
在基线和为期6个月的运动干预后，使用匹兹堡睡眠质量指数（PSQI）进行测量。PSQI评分>5表明睡眠质量差。采用线性回归评估PSQI评分与人体测量指标及心脏代谢健康标志物之间的关联，以及运动训练对这些关联的影响。
34名参与者在基线时完成了PSQI测量，干预后有29人完成：无运动对照组（n = 9）、HIIT组（n = 12）和CAET组（n = 8）。基线时，79%的参与者睡眠质量差。基线PSQI评分与体重指数、腰围、体重、糖化血红蛋白和胰岛素抵抗呈正相关。对照组、HIIT组和CAET组的PSQI评分平均变化分别为-0.4（标准差1.1）、-0.7（标准差0.6）和-0.5（标准差0.9）。对于HIIT组参与者，PSQI评分的变化与体重变化（B = 0.27，95%置信区间0.10 - 0.45）和腰围变化（B = 0.09，95%置信区间0.02 - 0.17）相关。
大多数参与者睡眠质量差，这与较差的人体测量指标及心脏代谢健康标志物相关。运动训练后PSQI评分无统计学显著变化。在HIIT训练中，睡眠效率评分的降低与体重和腰围的减少相关。需要进一步研究以确定运动训练对睡眠质量的影响。
