摘要

Pressure ulcers usually occur over the ischial tuberosity of the people bound in wheelchairs. The objective of the study is to make a comparison between age, genders, and different factors of body build, including height, weight, body mass index, body fat percentage, waist circumference, buttock circumference, and mid-upper arm circumference, on their influences upon pressure under the ischial tuberosity.
This experiment is a cross-sectional comparison study. We recruited 38 participants, including twenty-five males and thirteen females aged from 24 to 57. Our results showed that there were no differences on pressure under the ischial tuberosity among people of different age and genders. To explore the association between body build and pressure under the ischial tuberosity, Pearson correlation analysis revealed all factors of body build other than height and waist circumference were remarkably related to pressure under the ischial tuberosity. Furthermore simple linear regression to analyze the effects of weight, body mass index, body fat percentage, mid-upper arm circumference and buttock circumference on pressure under the ischial tuberosity respectively disclosed that the explanatory power (r^2=0.309) of body fat percentage was higher than those of body mass index and buttock circumference, and much higher than those of mid-upper arm circumference and weight. Finally the result of stratification of multiple linear regression showed the combination of body fat percentage, age, and gender had the highest explanatory power of 0.402, followed by the combination of body mass index, age, and gender with the explanatory power of 0.315.
The conclusion is that, among factors of body build, body fat percentage is the most influential upon pressure under the ischial tuberosity. However, the combination of body mass index, age, and gender can reach similar explanatory power to body fat percentage.
