Abstract only Background: Frailty is associated with higher risk of cardiovascular disease (CVD). Recently, oral hypofunction, a disease in which the oral function is complexly reduced not only by ageing but also by a variety of factors, is regarded as a risk factor for frailty. Also, locomotive syndrome, which is defined as reduced mobility due to impaired locomotive organs, is reported to have close association with frailty and oral hypofunction. However, no studies evaluated the association of oral hypofunction / locomotive syndrome and arterial stiffness, a marker of CVD. The objective of this study is to evaluate the association of oral hypofunction / locomotive syndrome and arterial stiffness. Hypothesis: We hypothesized that subjects with oral hypofunction or locomotive syndrome have increased arterial stiffness compared to those without oral hypofunction and locomotive syndrome. Methods: Japanese Subjects above 50 years old who underwent annual health-checkup were enrolled in this cross-sectional study. Subjects with history of CVD and dementia were excluded. Arterial stiffness was evaluated by brachial-ankle pulse wave velocity (baPWV). Oral hypofunction was evaluated the methods based on the guidance by the Japanese Association for Dental Science. Seven oral factors, oral hygiene, oral moisture, occlusal force, tongue-lip motor function, tongue pressure, masticatory function, and swallowing function were assessed. Oral hypofunction was diagnosed if more than 3 factors showed deterioration. Locomotive syndrome was evaluated by the questionnaires (GLFS-25) and physical performance tests consisted of those for quadriceps muscle strength, a two-step test, and a stand-up test according to the guidance by the Japanese Orthopedic Association. The association of oral hypofunction / locomotive syndrome and baPWV was assessed by multivariable linear regression analysis adjusted for conventional CVD risk factors. Results: Among 148 subjects (mean age: 59±7 years), 82 subjects (55%) had either oral hypofunction or locomotive syndrome (oral hypofunction: 33 subjects, locomotive syndrome: 65 subjects). BaPWV in subjects with either oral hypofunction or locomotive syndrome was significantly higher than subjects with none of them (mean baPWV: 1501±292 v.s. 1368±238cm/sec, p=0.003). Multivariable linear regression analysis revealed that the existence of either oral hypofunction or locomotive syndrome was significantly associated with increased arterial stiffness
