“…To do this they have addressed the factors determining fertility (Bay, Del Popolo, & Ferrando, 2004), the legal protection of motherhood (Casas & Valenzuela, 2011), women's rights (Pieper Mooney, 2009), maternal health policies (Alvarado & Herrera, 2011), the tensions between motherhood, work, and health (Ansoleaga, 2011;Pemjean et al, 2011), the reconfiguration of gender relations (PNUD, 2010) and family structures (Arriagada, 2004;Salvo & Gonzálvez, 2015;Valdés, 2007), adoption and assisted reproduction (Herrera, 2011), childbirth (Murray, 2012), and the cultural mandates of women's self-identity (Montecino, 1990). The few studies that address time have described the quantitative variations of the frequency of childbearing and the timing of the transition to motherhood over time (Donoso, 2007;Fuentes, Jesam, Devoto, Angarita, Galleguillos, Torres, & Mackenna, 2010;INE, 2006;MINSAL et al, 2014;Schkolnik, 2004;SERNAM & INE, 2004). Some of these studies have also explored women's reasons and justifications behind the temporal transformations in reproductive behaviour (Cerda, 2010;Montilva, 2008;SERNAM, 2012).…”
