Nursing staff suffer from various level of stress and burnout. We aimed to assess the effect of 12 weeks of structured yoga on stress and the professional quality of life among nursing staff.
An open-label, phase-II randomized clinical trial was undertaken considering a sample size of convenience was done. In service nursing staff were randomized (1:1) to intervention group and wait-list control group. Primary outcome was perceived stress which was measured by Perceived Stress Scale (PSS). Secondary measures were professional quality measured by Professional Quality of Life (ProQOL) scale, blood pressure, serum cortisol, and high-sensitive C-reactive protein. Both the per-protocol and intention to treat analysis was done.
Total 113 participants were allocated to intervention group (n = 58, mean = 35 years, SD = 7.9 years) and wait-list control group (n = 55, mean = 32.5 years, SD = 6.8 years). After 12 weeks, 19 participants of intervention group and 32 participants of wait-list control group were included in the per-protocol analysis. Follow-up mean PSS score was 15.4 (95% CI 12.6-18.2, SD 5.8) in intervention group, 20.7 (95% CI 19.7-21.7, SD 2.8) in wait-list control group (p-value < 0.0001). The other parameters didn't differ between the groups and from baseline to end line too.
The finding showed supervised structured yoga may be efficacious to reduce stress. Studies with larger sample size are needed to confirm the findings.
It was approved by the Institute Ethics Committee (Reference no: IECPG-543/20.12.2017, RT-57/31.01.2018) and was registered prospectively in the Clinical Trial Registry of India prospectively (No. CTRI/2018/02/012206).
护理人员承受着不同程度的压力和倦怠。我们旨在评估 12 周结构化瑜伽对护理人员压力和专业生活质量的影响。
考虑到方便的样本量，进行了一项开放标签、二期随机临床试验。在职护理人员按照 1:1 的比例随机分配到干预组和候补对照组。主要结局是通过感知压力量表（PSS）测量的感知压力。次要测量指标包括专业生活质量（ProQOL）量表、血压、血清皮质醇和高敏 C 反应蛋白。进行了意向治疗和符合方案分析。
共有 113 名参与者被分配到干预组（n=58，平均年龄 35 岁，标准差 7.9 岁）和候补对照组（n=55，平均年龄 32.5 岁，标准差 6.8 岁）。12 周后，干预组有 19 名参与者和候补对照组有 32 名参与者纳入符合方案分析。干预组随访时的平均 PSS 评分是 15.4（95%CI 12.6-18.2，SD 5.8），候补对照组是 20.7（95%CI 19.7-21.7，SD 2.8）（p 值<0.0001）。其他参数在组间和从基线到终点均无差异。
研究结果表明，监督结构化瑜伽可能对减轻压力有效。需要更大样本量的研究来证实这些发现。
该研究得到了机构伦理委员会的批准（参考号：IECPG-543/20.12.2017，RT-57/31.01.2018），并在印度临床试验注册处进行了前瞻性注册（注册号：CTRI/2018/02/012206）。
