The purpose of this study was to evaluate the effects of a yoga program provided to workers in small businesses to reduce cardiovascular disease (CVD) risk factors. A nonequivalent control group pre/post-test design was used. The experimental group (n = 31) was assigned a yoga program consisting of yoga postures designed for meditation, strengthening, stretching, and balancing, given twice weekly for 12 weeks. The control group (n = 38) was given no other intervention. The mean age was 48.1 years old in the experimental group and 47.7 years old in the control group. Three trained investigators collected the questionnaires and one month after completing the 12-week yoga program, the same questionnaires that were administered at baseline were again administered. Psychosocial variables (depressive symptoms and job stress), health promotion behaviors, and body measurements (weight and waist circumference) were measured for the program evaluation. The yoga program was effective in improving waist circumference (from 81.8 to 79.2, p < 0.001) and diastolic blood pressure (from 81.0 to 79.1, p = 0.004) as compared to the control group. Furthermore, the experimental group’s job stress score decreased from 1.38 to 1.02, but it was not statistically significant (p = 0.240). A yoga program could be a useful intervention for workers with CVD risk factors, but it was not effective in psychological factors such as job stress and depression. A long-term intervention approach is important to confirm the psychosocial effect. Therefore, future research is needed to investigate the long-term outcomes of such interventions. View Full-Text
