The combined associations of social participation and support with self-rated health and dietary satisfaction in men with spinal cord injury.

Abstract

Cross-sectional study. (1) To examine the association between social participation (SP) and social support (SS) with self-rated health and dietary satisfaction and (2) to explore the joint association and interactions of SP and SS with self-rated health and dietary satisfaction in community-dwelling adult men with spinal cord injury. Members of the Spinal Injuries Japan organization. We sent questionnaires to 2731 registered members of Spinal Injuries Japan via mail. Responses from 625 men aged ⩾40 years were analyzed. Respondents were categorized into four groups: SP/sufficient SS, SP/insufficient SS, no SP/sufficient SS and no SP/insufficient SS. Logistic regression analysis was used to examine the odds ratios for self-rated health and dietary satisfaction according to the SP/SS categories. Relative to participants in the no SP/insufficient SS category, those in the SP/sufficient SS group demonstrated significantly better self-rated health and dietary satisfaction after adjusting for sociodemographic variables. There was no interaction between SP and SS in self-rated health or dietary satisfaction. SP was associated with high self-rated health without SS, and sufficient SS was associated with high dietary satisfaction without SP. Relative to other groups, participants with SP/sufficient SS demonstrated higher self-rated health and dietary satisfaction. Sufficient SS was associated with high dietary satisfaction without SP. This study suggested the importance of addressing aspects of both SP and SS using self-rated health and dietary satisfaction as outcome measures in health promotion programs.
