In addition to basic characteristics, lifestyle variables, and general health status, participants underwent assessment of oral function and respiratory function by two certified dentists.ResultsCompared to general priests (n = 23), expert chanters (n = 49) were significantly higher in peak expiratory flow (PEF), forced vital capacity (FVC), and hyoid displacement (⊿HD). In the two multiple regression analyses which include PEF and FVC as the dependent variables, expert group demonstrated significantly better function.DiscussionConsidering its historical and cultural background, the idea of using sutra chanting has potential in a healthcare program for older people at risk of declining oral and respiratory functions.
