Self-management Among Elderly Patients With Hypertension and Its Association With Individual and Social Environmental Factors in China.

BACKGROUND: The hypertension control rate in China is much lower than that in developed countries. Self-management among elderly patients with hypertension can improve blood pressure control; thus, it is necessary to explore its association with individual and social environmental factors. OBJECTIVE: Our objective was to investigate self-management among elderly patients with hypertension in China and its association with individual and social environmental factors based on the social ecological model. METHODS: A total of 301 elderly patients with hypertension were recruited to do a questionnaire survey based on the social ecological model, which included the General Demographic Information Questionnaire, Hypertension Patients Self-Management Behavior Rating Scale, World Health Organization Well-Being Index, Family APGAR Index, and Social Support Rating Scale. RESULTS: The lowest level of self-management behaviors was in exercise management, and the highest was in medication management. The results of multiple linear regression analysis showed that well-being, family function, sex, education level, and age were pivotal individual and social environmental factors influencing self-management behaviors among elderly patients with hypertension. CONCLUSIONS: There is a need to develop and test interventions that improve self-management in elderly patients with hypertension. Specifically, individualized interventions to promote exercise among elderly persons with hypertension who are single and living alone are needed. Male patients with a lower education level, poor well-being, poor family function, and the lowest self-management levels are a key population to target.

The effect of continuous nursing intervention guided by chronotherapeutics on ambulatory blood pressure of older hypertensive patients in the community.

AIMS AND OBJECTIVES: To explore the effect of continuous nursing intervention guided by chronotherapeutics so as to provide the easy, noninvasive, effective and acceptable intervention for older hypertensive patients in the community. BACKGROUND: Many researchers studied the effect of administration at different times on blood pressure control and circadian rhythm. However, the individual administrative time was set ambiguously in previous studies. DESIGN: A semi-experimental study. METHODS: In the study, 90 eligible patients were recruited and separated into three groups randomly, which were the control group, intervention group A (behaviour and chronotherapy intervention) and intervention group B (behaviour intervention). At 6 and 12 months after the study, the intervention groups were measured 24-hour ambulatory blood pressure monitoring. RESULTS: There were significant differences in ambulatory blood pressure monitoring parameters of the two intervention groups at different measurement times, and there were interaction between measurement time and different groups. The number of patients with dipper increased and reverse dipper decreased in group A as the intervention applied. There were statistical differences between two groups. The number of patients with morning surge in group A decreased more, and there were statistical differences between two groups at six months after the intervention. CONCLUSIONS: The behaviour and chronotherapy intervention based on the patients' ambulatory blood pressure monitoring can control casual blood pressure much better and last longer, which can also improve patients' indexes of ambulatory blood pressure monitoring better than behaviour intervention only. The behaviour and chronotherapy intervention can increase patients' nocturnal blood pressure drop, increase the number of patients with dipper and decrease reverse dipper, and improve blood pressure surge in the morning. RELEVANCE TO CLINICAL PRACTICE: Nurses can use continuous nursing intervention guided by chronotherapeutics to help improve hypertension of older patients better in the community.

Pivotal factors interfering in 24-hour blood pressure fluctuation and arterial stiffness in a community of Chinese elderly hypertensive patients.

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 night. 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.
