Social network size and its relationship to domains of quality-of-life among older persons living with HIV.

ABSTRACT

Gerontological research suggests that social network characteristics are key elements of successful aging as they are related to a positive quality-of-life (QoL). Less is known about the social networks of persons aging with HIV. To describe social network characteristics and assess the effect of social network size on QoL, a sample of 146 OPWH (age ≥50) was recruited from an outpatient HIV clinic in Atlanta, GA. Social network size was assessed using Cohen's social network index (SNI). Domains of QoL (physical, emotional, and social) were assessed using the RAND-36. Descriptive analyses were used to determine the frequency of contact within social networks and multivariable regression models were used to assess the relationship between SNI and three domains of QoL controlling for potential covariates. Participants were predominantly male (60%), heterosexual (63%), and African American (86%). Regular contact occurred most frequently with friends (82%) and relatives (77%). Multivariable modeling revealed that SNI explained 58% of the variance in emotional QoL (R2 = 0.58, F(8, 137) = 25.48, p < .001). Findings provide basis for potential interventions focused on the specific social network to improve emotional QoL of this vulnerable population.
