Within Berkman et al.'s (2000) framework, we examined sociodemographic correlates of social networks (SN) and social support (SS) in 155 heart patients (33 women, 122 men), who completed measures of sociodemographics, SN, and SS. Hierarchical regression analyses examined the relationship between sociodemographic factors and SN; and between sociodemographic factors, SN, and SS. Higher social status and more income were related to larger, more diverse networks and more SS. Higher social status and being married were related to more SS. Being married was related to more belonging and tangible support. Results show the complex relationship between higher level social factors and specific SS functions offering areas for future interventions to increase SS in heart patients.
