Abstract

Background

This project aimed to assess the impact of yoga on stress, metabolic parameters and cognition (attention & concentration) in adolescents, aged 13–15 years from public and private schools in two cities (Chennai and New Delhi) in India.

Methods

The study recruited 2000 adolescents from 24 schools in a cluster randomized controlled trial design. The yoga group participants underwent 17 yoga sessions, which included: pranayama, basic asanas, meditation and relaxation exercises. Yoga sessions, were held in the school premises once a week. A total of five awareness talks on healthy lifestyle were delivered once a month to the education group. ADOlescence Stress Scale (ADOSS), salivary cortisol, metabolic and clinical parameters and Letter Cancellation Test (LCT) score were measured at baseline and post-intervention (5–6 months).

Results

The yoga group showed statistically significant differences in the mean ADOSS score, metabolic parameters, salivary cortisol, and LCT scores compared to the education group. In the intention- to- treat analysis, a significant reduction [5.11, 95% CI (4.78, 5.36), p = 0.001] in ADOSS score was seen in the yoga group compared to education.

Conclusion

Implementation of a 17-week standardized yoga program at the school level significantly decreased stress, improved attention and concentration, metabolic and clinical parameters in Indian adolescents.

Trial registration

This trial was registered at Clinical Trials Registry, India (CTRI/2017/08/009203).

瑜伽对印度青少年压力、代谢参数和认知的影响:一项随机对照试验

背景该项目旨在评估瑜伽对印度两个城市（金奈和新德里）公立和私立学校13-15岁青少年的压力、代谢参数和认知（注意力和注意力）的影响。方法采用整群随机对照试验设计，从24所学校招募2000名青少年。瑜伽组参与者接受了17次瑜伽训练，其中包括：调息、基本体式、冥想和放松练习。瑜伽课程，每周在学校举行一次。每月向教育小组进行一次关于健康生活方式的宣传讲座，共五次。在基线和干预后（5-6个月）测量青春期应激量表（ADOSS）、唾液皮质醇、代谢和临床参数以及字母消除测试（LCT）评分。结果与教育组相比，瑜伽组在ADOSS平均得分、代谢参数、唾液皮质醇和LCT得分方面存在统计学显著差异。在意向治疗分析中，与教育相比，瑜伽组的ADOSS评分显著降低[5.11，95%CI（4.78，5.36），p=0.001]。结论在学校实施为期17周的标准化瑜伽项目显著降低了印度青少年的压力，提高了他们的注意力和专注力、代谢和临床参数。试验注册本试验在印度临床试验注册中心注册（CTRI/2017/08/009203）。
