“…For some variables, cutoff points already established in literature were adopted, namely: "baby's birth weight," in which values below 1,500 grams (g) were considered very low weight; low birth weight, equal to or greater than 1,500 g and below 2,500 g; and adequate weight, equal to or greater than 2,500 g [24]; and; "gestational age", preterm, less than 37 weeks of gestation; term, between 37 and 41 weeks and; post-term, greater than or equal to 42 weeks [25]. For the following variables: "maternal age" [11], "lives with a partner" [9,[12][13], "maternal work" [19], "maternal parity" [9,[12][13], "prenatal service" [13,19], "delivery type" [9,[12][13]19], "smoking" [12,18] and "alcoholism" [18] the categorization we employed was utilized in studies with donor mothers of HM. For variables "child age", "donated milk amount" and "donation time", these categories were adopted in order to facilitate data analysis, as there was information in registration form frequently recorded in different and non-standard ways.…”
