Relationship Between Upper Arm Muscle Index and Upper Arm Dimensions in Blood Pressure Measurement in Symmetrical Upper Arms: Statistical and Classification and Regression Tree Analysis

摘要

Objective: to identify the influence of upper arm muscle index (AMI) and upper arm dimensions on the measurement of blood pressure (BP). Methodology: 489 university students were evaluated in Divinópolis, Brazil and data were collected on anthropometric and BP measurements and elaborated multiple linear regression and regression tree models using data mining techniques. Results: length arm (AL) and arm circumference (AC) showed positive correlation with systolic blood pressure (SBP) and diastolic blood pressure (DBP). The AMI presented positive correlation with SBP and negative correlation with DBP. The regression tree showed interactions between BP and AL, AC and AMI. Conclusion: BP values in the upper right upper arm were higher than in the left upper arm in population of healthy young adults. AL and AC were predictors of overestimation of indirect measurement of SBP and DBP. AMI overestimates SBP and underestimates DBP. There were interactions between arm dimensions and BP.
