Relationship between upper arm muscle index and upper arm dimensions in blood pressure measurement in symmetrical upper arms: statistical application and data mining

The objective of this study was to identify the influence of upper arm muscle index and upper arm dimensions on the measurement of blood pressure in symmetrical upper arms. Arterial hypertension (AH) is one of the most important diseases from an epidemiological and economic perspective. The diagnosis of AH is made mainly from the indirect measurement of blood pressure (BP). However, there are errors in the usual practice of the procedure and the standardized technique does not consider the differences in the body composition of the upper arm. The higher upper arm muscle index (AMI) may increase the density and overestimate the BP measurement. The relationship between these variables may contribute to the improvement on quality of BP measurement. Methodology: 489 university students aged 18 to 29 years 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: the anthropometric variables were statistically differents inter-arm, except upper arm length (AL), and upper arm circumference (AC). AL and AC showed a positive correlation with systolic blood pressure (SBP) and diastolic blood pressure (DBP). AMI presented a positive correlation with SBP and a negative correlation with DBP. Conclusion: Blood pressure values in the upper right upper arm were higher than in the left upper arm in the population of healthy young adults. AL and AC were predictors of overestimation of the indirect measurement of SBP and DBP. AMI overestimates SBP and underestimates DBP.
