A quasi-experimental study. main the leading cause of morbidity Setting. A community in Taipei City, Taixuan. and mortality worldwide and constitute Subjects. One hundred thirty-three adults aged 55 years and older. a major problem to medical science and Intervention.

Analysis. Generalized estimjiting equations were used to evaluate the changes.Results. Participants showed a greater drop in anxiety levels (ß = -2.57, p= .001) and DBP (ß = -7.02, p < .001) at the 12-week follow-up than did the controls. SBP significantly decreased in the 6-week follow-up and 12-week folloxo-up tests. The participants in the intervention achieved a greater drop in BMJ at the 6-week and 12-zueek follow-up visits than the controls. The interventions demonstrated decreased average WC at the 6-week and 12-week folhw-up visits as compared to tlie controls. Conclusion. The results highlight the long-term benefits of a TCC program in facilitating health promotion by reducing anxiety and risk factors for cardiovascular diseases. (Am f Health Promot 201328[l]:16-22.)
