“…Other studies from resource-limited settings suggest that parents' social class (Mukhtar-Yola et al, 2006) and available social support (Nabukeera-Barungi et al, 2007) are not significantly associated with adherence. Orphan status has also been associated with ART nonadherence in some studies (Cupsa et al, 2000;Vreeman, Wiehe, Ayaya, et al, 2008;Wachholz & Ferreira, 2007), but not in others (Hansudewechakul, Jourdain, Plangraun, & Team, 2006;Nabukeera-Barungi et al, 2007;Nyandiko et al, 2006;Safreed-Harmon et al, 2007), and this association differs by type of caregiver (Wachholz & Ferreira, 2007). The existing literature argues that the child's socioeconomic context plays a key role in adherence, but differences in the findings suggest we do not understand how these factors interact or which factors should be measured (Sankar, Golin, Simoni, Luborsky, & Pearson, 2006).…”
