“…The studies on the incidence of WB in several countries highlight the differences in the form of capturing and measuring, as well as in the conceptualization, besides the multiplicity of defining criteria for each country (and within the same country), which signals the need for caution in interpreting data (Bradaschia, 2007;León-Pérez, Escartín and Giorgi 2019;Salin et al, 2019). Research also portrays social, cultural, and geographical differences, as well as methodological ones, in the way of conducting the studies (Agervold 2007;Bradaschia 2007;Freitas, Heloani and Barreto 2008;Geoffrion et al 2017;Guimarães, Vasconcelos, Andrade, Stephanini and Rego 2005;León-Pérez et al, 2019;Rueda, Baptista and Cardoso 2015;Salin et al, 2019).…”
