Abstract: Aims and objectives. To explore which sociodemographic and clinical factors could interfere in the parameters of ambulatory blood pressure monitoring and determine the affecting factors of Ambulatory Arterial Stiffness Index. Background. Although the clinical relevance of ambulatory blood pressure monitoring and Ambulatory Arterial Stiffness Index have been studied, the explanation of their role and related interfering factors remains controversial in patients with different disease or age, etc. Design. Cross‐sectional study. Methods. The study was carried out between October 2008–October 2009. A convenience sample of hypertensive patients over 60 years old was recruited in China. Twenty‐four hour ambulatory blood pressure monitoring was carried out on the non‐dominant arm using an oscillometric device. Results. (1) All 95 patients completed the study and their ages ranged from 60–76 years. (2) There were statistical differences for certain parameters of ambulatory blood pressure monitoring between different characteristics of patients. Financial status was an important factor interfering in patients’ BP fluctuation, especially daytime and 24 hours systolic pressure. The higher body mass index the patients had, the higher the pressure was. (3) Multiple variants logistic analysis of Ambulatory Arterial Stiffness Index showed statistical differences only in coefficient variation of 24‐hour diastolic pressure and daytime systolic blood pressure. Conclusions. There are more factors that interfered with systolic pressure and diastolic pressure during the day than nigh. Patients who have less nocturnal dipping may have a higher night time systolic pressure and diastolic pressure. The coefficient of variation of 24 hours diastolic pressure and daytime systolic pressure contribute more to Ambulatory Arterial Stiffness Index which should arouse practitioners’ attention. Relevance to clinical practice. Ambulatory blood pressure monitoring should be used as a routine procedure, as well as Ambulatory Arterial Stiffness Index calculated for older hypertensive patients. The findings may be used to guide community health providers to pay more attention to the factors that may influence BP fluctuation and Ambulatory Arterial Stiffness Index according to individual’s characteristics.
