Social network factors associated with perceived quality of life. The San Luis Valley Health and Aging Study.

Demographic and social network factors associations with perceived quality of life (PQOL) were examined in a sample of rural Hispanic and non-Hispanic White (NHW) elderly. A 20-item PQOL scale measured participants' satisfaction with multiple facets of their lives. Age, gender, marital status, and living alone were not associated with this outcome. Hispanic persons with higher incomes had consistently higher ratings of quality of life compared to NHWs. More education was associated with a higher PQOL rating only among NHWs. More close friends and relatives, visiting in homes, and participation in outside activities were all independently related to PQOL. Interaction tests showed that the impact of social networks was stronger in NHWs. These findings suggest that network size and contact are important social factors that can improve quality of life for both ethnic groups. However, differences may need to be examined when judging the magnitude of these associations and when planning interventions.
