The evolution of bioimpedance analysis: From traditional methods to wearable technology.

Body composition assessments are essential for understanding health and nutritional status. Traditional methods like deuterium oxide dilution, while accurate, are impractical due to cost and complexity. Bioimpedance analysis (BIA) has emerged as a preferred clinical and research technique.

Muscle quality index comparisons between Hispanics and non-Hispanic Caucasians using dual energy X-ray absorptiometry and handgrip strength.

Background & Aims: Muscle quality index (MQI) can be computed in various ways. Also, many studies have evaluated MQI in older adults and non-Hispanic populations. The aim of this study was to compare various muscle quality indexes between Hispanics and non-Hispanic Caucasians when stratifying grip strength and appendicular lean mass measurements.

Deuterium oxide validation of bioimpedance total body water estimates in Hispanic adults.

Background: To date, body composition assessments in Hispanics, computed via bioimpedance devices, have primarily focused on body fat percent, fat mass, and fat-free mass instead of total body water (TBW). Additionally, virtually no information is available on which type of bioimpedance device is preferred for TBW assessments in Hispanic populations.

Purpose: The purpose of this study was to validate two bioimpedance devices for the estimate of TBW in Hispanics adults when using a criterion deuterium oxide (DO) technique.
