Ioga na saúde do trabalhador: revisão integrativa de estudos de intervenção

Abstract

Background: Effects of yoga on physical and mental health have been investigated in several fields. Objective: To investigate and analyze results of yoga interventions in the workplace reported along 10 years after the formulation of the National Policy of Integrative and Complementary Practices. Method: We located 10 studies published from 2006 to 2015 which met the inclusion criteria, included in databases Cumulative Index of Nursing and Allied Health Literature (CINAHL), Medical Literature Analyses and Retrieval System Online (MEDLINE), Web of Science, Scopus, Cochrane and Scientific Electronic Library Online (SciELO). Analyzed variables were: publication year, authorship, title, aims, results, and conclusions. Interventions were characterized based on yoga style, practices implemented, frequency and duration of sessions, duration of intervention, measurement instruments, and additional interventions. Results: Our findings suggest that yoga has physical and psychological effects on workers from different professional categories. However, we did not find benefits for some conditions, and yoga practice does not have the same positive effects on all practitioners. Workers’ adherence to programs influences the results of research. Many studies did not clearly describe the implemented programs. Conclusion: The characteristics of interventions show substantial differences among programs, which enable a synthesis, but not comparisons.
