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

Ergonomía de modelos anatómicos de sostén para lactancia materna: una contribución de la enfermería

ABSTRACT

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 (χ2) 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.
