Compliance with care and poor sleep quality among hypertensive adults in a mountainous area of Hubei Province, People's Republic of China.

Abstract

BackgroundLittle information is available concerning the relationship between compliance with hypertensive care and poor quality of sleep among Chinese adults in rural areas. This study aimed to evaluate the association between the compliance with hypertensive care and sleep quality for hypertension of adults in a mountainous area in People's Republic of China.MethodsA total of 551 hypertensive patients (30–96 years of age) living in a remote mountainous area were recruited. Poor sleep quality was assessed using the standard Pittsburgh Sleep Quality Index (PSQI), and compliance with care was measured based on the Compliance of Hypertensive Patients Scale (CHPS). Hypertension was defined as blood pressure ≥140/90 mmHg or treated with antihypertensive medication. The associations between sleep quality and compliance variables were examined using Pearson’s correlation. Multiple linear regressions were established to verify significant variables associated with respondents’ compliance with care and poor sleep quality.ResultsThe average age of the sample was 67.15 years (SD=10.20), and 56.44% of the participants were female. The mean CHPS total score was 41.97 (SD=5.91), and the PSQI total score was 7.91 on average (SD=4.10). Correlation analysis revealed that patients with higher intention, healthier lifestyle, positive attitude and total compliance were more likely to have an increased risk of poor sleep quality. According to the results of multiple linear regression analyses, hypertension compliance was significantly associated with being female, married, non-rural residence and years of hypertension, while poor sleep quality had a significant association with living in rural areas, having concomitant disease and poor hypertension compliance.ConclusionsThere is a significant association between hypertension compliance and poor sleep quality. Future intervention programs should focus on improving compliance behavior as a modifiable background factor for sleep quality.
