Abstract

The objective of this study was to investigate a mediating relationship between social support and disturbed sleep in cases surviving myocardial infarction. The case-referent studies, Stockholm Heart Epidemiological Program (SHEEP) and Västernorrland Heart Epidemiological Program (VHEEP) were used comprising 6231 participants (2046 women). Referents were randomly selected. Disturbed sleep was operationalized by the Karolinska Sleep Questionnaire, network support by the Availability of Social Integration Index and emotional support by the Availability of Attachment Index. Mediating associations were tested with logistic regression. The results show that disturbed sleep may act as a mediator between low network support and myocardial infarction in women.
