By calculating data identifying inequalities with the Ministry of Health in random regions of Brazil, in 2012, Barufi, Haddad and Paez discovered numerous problems : ineffective due to its inaccessibility, few socio-economic improvements have prevented many poor people in Brazil from accessing any social mobility, and finally, without appropriate infrastructure, there is little that can be done to reduce the infant mortality rate (pp. 6-8). Relatedly, Narayan Sastry found, through his studies of urban and rural infant mortality in 1997, that these community characteristics have a strong impact but do not have a direct effect on infant mortality in Brazil (p. 999 -1001). In simpler terms, there are DSSs that are not examined and have greater impacts but are not implemented due to lack of studies. Although its numbers don't overtly infer it, if one community has such a large impact, imagine what the preventive care specified for each community could do to influence the IMR of those regions. As presented, infant mortality is clearly a problem, but it is often difficult to precisely identify the main contributing factor. In the following section, the causes and effects of infant mortality will be
