“…Since FC was first introduced, studies of acceptability and usage have been widely conducted among sex workers (Witte, El-Bassel, Wada, Gray, & Wallace, 1999; Jivasak-Apimas et al, 2001; Cheng et al, 2002; Zachariah, Harries, Buhendwa, Spielman, Chantulo, & Bakali, 2003; Thomsen et al, 2006; Hoke et al, 2007; Lara, Grossman, Munoz, Rosario, Gomez, & Garcia, 2009; Mack, Grey, Amsterdam, Matta, & Williamson, 2010; Liao et al, 2011a; Liao et al, 2011b), couples (Musaba, Morrison, Sunkutu, & Wong, 1998; Lawson et al, 2003; Smita et al, 2005; Lameiras Fernandez, Failde Garrido, Castro, Nunez Mangana, Carrera Fernandez, & Foltz, 2008), patients from clinics (Artz et al, 2000; Hoffman, Exner, Leu, Ehrhardt, & Stein, 2003; Kulczycki, Kim, Duerr, Jamieson, & Macaluso, 2004), and volunteers (Barbosa, Kalckmann, Berquo, & Stein, 2007). Despite numerous studies demonstrating high acceptability of FC among various populations, its use remains low and a large proportion of women who initially tried it did not sustain its use (Hoffman et al, 2004; Gallo, Kilbourne-Brook, & Coffey, 2012).…”
