Aim:
To examine the influence of body mass index, bioimpedance, and skin folds on the distribution of body interface pressure in regions with the potential to develop pressure ulcers in contact with support surfaces.
Design:
This was a descriptive and analytical study.
Methods:
Twenty healthy volunteer adults were investigated in April 2017. Body mass index, skin folds, waist circumference, bioimpedance, and interface pressure on bony prominences were investigated. Descriptive statistics and correlations were analysed.
Results:
Peak pressures in the subscapular region presented moderate and significant correlations with body mass index, waist circumference, total and extracellular body water, fat-free mass, and lean mass per body segment. The peak pressure on the right heel showed a moderate correlation with total and extracellular body water, fat-free mass, and lean mass per segment.
Conclusion:
The need for multicenter research was evident, focusing on bioimpedance assessment as a risk factor for the development of pressure ulcers.
