[Does breastfeeding position influence the onset of nipple trauma?].

The aim of the study was to identify the breast feeding position and holding variables related to nipple trauma. This case-control study assessed the onset of nipple trauma among women hospitalized at a University Hospital in the city of São Paulo, in 2004 and 2005. Subjects were puerperae diagnosed with unilateral or bilateral nipple trauma. Data analysis was performed using chi-square, Student's t, and odds ratio tests (CI = 95%) and correspondence analysis. Participants were 146 puerperal women and their newborns, being 73 cases and 73 controls. Statistically significant position and holding variables for causing lesions were the following: newborns with their necks bent/contorted, chin away from the breast and lip-related defect (turned inward). Trauma prevention at the beginning of breast feeding is crucial for continuing this practice. Following adequate positioning is decisive for establishing effective and prolonged breast feeding.
