Unique Identifier : AIDSLINE ICA10/94370218 AB OBJECTIVE: To determine whether measures of social support are associated with progression of HIV disease progression in a prospective cohort of homosexual men. METHODS: 357 subjects [133 seroprevalent (SP); 64 seroincident (SI); 160 seronegative (SN)] provided demographic and social support data and laboratory specimens at two annual cycles (1992 & 1993), and were AIDS-free at the time CD4 counts were determined in 1992. Social support measures were network size (NSz) and a 26-item Instrumental-Expressive Social Support Scale (IES). IES was coded 0 (rarely/never) vs. 1 (mostly/always) for each of the 26 items, and the upper tertile of the summed IES score was used to categorize subjects as high IES (hiIES) vs. low IES (loIES). NSz below the lowest tertile differentiated between networks which were considered small (smNSz) versus large (lgNSz). hiIES and smNSz indicate low social support. ANCOVA were conducted adjusting for baseline CD4 counts and CDC stage in 1992, where the dependent variable was % of CD4 cells lost between 1992 and 1993. Chi-square tests compared progression to AIDS among subjects with hiIES vs. loIES and smNSz vs. lgNSz. RESULTS: No differences between HIV+ (N = 153) and SN (N = 160) individuals were found in change in IES score or NSz between 92 and 93 (p = 0.279, and p = 0.377, respectively). Among 197 HIV+ men at baseline in 1992, there were no significant differences between hiIES vs. loIES subjects in mean CD4 counts, but those with high IES scores had slightly more symptoms. Even after controlling for these baseline factors, hiIES subjects experienced a greater mean % CD4 loss than loIES men (-19% vs. -7%; p = 0.034). Similarly, smNSz subjects experienced a greater mean % CD4 loss than lgNSz men (-19% vs. -8%; p = 0.043). AIDS progression was also associated with hiIES. By 1993, more hiIES men developed AIDS than loIES men whether they were at CDC stage 1 at baseline (15.4% vs 6.9%) or at higher stages (30.8% vs 22.0%). CONCLUSIONS: Low social support may be associated with subsequent CD4 cell loss and HIV disease progression among homosexual men. Further prospective analyses are required to determine the direction of causality between determinants of low social support and faster progression to AIDS.
