Effect of a home-based simple yoga program in child-care workers: a randomized controlled trial.

Abstract Objectives: This study investigated the effect of a brief, simple, home-based yoga program on body pain and health status in child-care workers. Design: This was a randomized, controlled trial comparing a home-based yoga group and a control group. Participants: The trial comprised 98 healthy female nursery school and kindergarten teachers. Interventions: A DVD of a simple home-based yoga program was provided for a period of 2 weeks. Outcome measures: The primary outcome measure was the reported change in body pain at 2 weeks (after intervention) and 4 weeks (follow-up). The secondary outcome measure was the 30-item General Health Questionnaire (GHQ30) score and physical function. Results: The 67 yoga group participants reported improved menstrual pain at 4 weeks; menstrual pain was reduced from 57.0±27.8 to 37.8±26.7 in the yoga group, versus 52.4±36.5 to 46.9±32.1 in the control group (change from baseline in the yoga group versus change from baseline in the control group, −15.3 points; p=0.044)...
