Ergonomics of anatomical bra models for breastfeeding: a contribution of nursing

Objectives: to analyze the ergonomics of two models of breastfeeding bras. Methods: descriptive study carried out with 152 infants in a Brazilian university hospital.The prototypes were separated into two groups (A and B). To compare the two bra models, the Odds Ratio (OR) was used as a measure of the strength of the association. In subjective perceptions, the Modified Borg Scale, and the chi-square test of independence (chi 2) were used. To compare the two prototypes, the Z test and logistic regression analysis were performed. A significance level of 5% was considered. Results: the bra in group B was more suitable for ergonomics of physical and psycho-aesthetic comfort than the bra in group A (p < 0.0001), according to the logistic regression tests. Conclusions: modeling B was ergonomically adequate, with usability and evaluation criteria centered on breastfeeding women.

Automated summary

The study compared the ergonomics of two models of breastfeeding bras, with results showing that the bra in group B performed better in terms of physical and psycho-aesthetic comfort, meeting the needs of breastfeeding women.
