“…Socioeconomic factors can be divided into those factors related to social or environmental variables, economic factors, and those related to the lifestyle of patients. Among the studies analysed, we identified four studies that showed a significant effect of social or environmental factors (i.e., social interaction and support networks) on treatment adherence (Siregar & Andayani, 2020;Zullig et al, 2015;Reddy et al, 2017;Park et al, 2015). Concerning the set of economic factors, several studies reported a significant association between adherence to treatment and financial status (Wooldrich et al, 2015;Crowley et al, 2012;McAlister et al, 2019;Shankari, 2020), education and literacy (Siregar and Andayani, 2020;Crowley et al, 2012;Al-Haj Mohd et al, 2016), employment (Sieben et al, 2021;Zullig et al, 2015;Crowley et al, 2012), and living condition of patients (Meggetto et al, 2017;Tola et al, 2016;Wooldrich et al, 2015).…”
