Abstract
Although sleep problems are common among patients with coronary heart disease (CHD), there is a lack of prospective research examining its influence on health consequences over time. This study investigated whether poor sleep quality predicted patients' decline in physical health functioning over 6 months and whether social support buffered its detrimental effect. Participants were 185 patients with CHD, who completed measures of sleep, psychosocial characteristics, and physical health functioning at baseline and 6 months. Hierarchical regression analyses were conducted to examine whether global sleep index and its subscales, including sleep efficiency, perceived sleep quality, and daily disturbances (sleep disturbances and daytime dysfunction), predicted the decline of physical health functioning at 6 months. Social support was examined for its moderating effect in buffering the negative influence of poor sleep quality on physical health functioning over 6 months. Findings showed that poorer global sleep index, especially subscales of daily disturbances and lower sleep efficiency, significantly predicted greater decline of physical health functioning at 6 months, even after adjusting for covariates, including baseline functioning and depression. Moreover, social support was found to buffer the detrimental impact of poor sleep quality, especially low sleep efficiency, on 6-month physical health functioning. Findings suggest that improving sleep quality for patients with CHD may be promising to facilitate their long-term health maintenance.
期刊介绍:
Behavioral Medicine is a multidisciplinary peer-reviewed journal, which fosters and promotes the exchange of knowledge and the advancement of theory in the field of behavioral medicine, including but not limited to understandings of disease prevention, health promotion, health disparities, identification of health risk factors, and interventions designed to reduce health risks, ameliorate health disparities, enhancing all aspects of health. The journal seeks to advance knowledge and theory in these domains in all segments of the population and across the lifespan, in local, national, and global contexts, and with an emphasis on the synergies that exist between biological, psychological, psychosocial, and structural factors as they related to these areas of study and across health states.
Behavioral Medicine publishes original empirical studies (experimental and observational research studies, quantitative and qualitative studies, evaluation studies) as well as clinical/case studies. The journal also publishes review articles, which provide systematic evaluations of the literature and propose alternative and innovative theoretical paradigms, as well as brief reports and responses to articles previously published in Behavioral Medicine.
