Effects of a T'ai Chi -Based Health Promotion Program on Metabolic Syndrome Markers,Health Behaviors,and Quality of Life in Middle-Aged Male Office Workers: A Randomized Trial

Abstract

Objectives:

To determine the effects of a t'ai chi-applied worksite health promotion program on metabolic syndrome markers, health behaviors, and quality of life in middle-aged male office workers at a high risk of metabolic syndrome.

Design:

A prospective randomized controlled study.

Setting:

Health center of a government office building in Korea.

Subjects:

Forty-three male office workers with two or more metabolic syndrome markers.

Interventions:

The office workers were randomly assigned either to an experimental group that received t'ai chi combined with health education twice weekly for 12 weeks, or to a control group that received health education only.

Outcome measures:

Blood sampling for metabolic syndrome markers and structured questionnaires for health behaviors and quality of life.

Results:

The experimental group showed significant reductions in systolic (t = −3.103, p = 0.003) and diastolic (t = −2.159, p = 0.037) blood pressures and the triglyceride level (t = −2.451, p = 0.019) compared with the control group. Those in the experimental group also performed health behaviors more frequently (t = 4.047, p < 0.001) and reported a significantly better quality of life (t = 3.193, p = 0.003) than those in the control group.

Conclusion:

The study findings show that t'ai chi was an effective adjunctive intervention in a worksite health promotion program for middle-aged office workers at a high risk of metabolic syndrome. Future studies should examine the long-term effects of t'ai chi-applied worksite health promotion programs in individuals with confirmed metabolic syndrome.
