Association of Body Shape Index (ABSI) with Hand Grip Strength

Area of Science:

• Human health and nutrition
• Biometrics and anthropometry

Background:

• Hand grip strength is a significant indicator of muscle strength and overall health.
• The relationship between grip strength and body shape, specifically the abdominal to height ratio (ABSI) and body mass index (BMI), requires further elucidation.

Purpose of the Study:

• To investigate the correlations between hand grip strength, ABSI, and BMI.
• To assess the association of these anthropometric measures with all-cause mortality.

Main Methods:

• Utilized data from the 2011-2014 National Health and Nutrition Examination Survey (NHANES) cohorts in the United States.
• Examined grip strength, ABSI, and BMI, including their associations with mortality during follow-up.
• Analyzed the impact of logarithmic transformation and standardization on these associations.

Main Results:

• Grip strength showed a negative correlation with ABSI and a positive correlation with BMI.
• Individuals with low grip strength or high ABSI exhibited increased mortality risk.
• BMI alone was not significantly associated with mortality hazard.

Conclusions:

• Body shape, as indicated by ABSI, is inversely related to grip strength, suggesting central adiposity is linked to reduced muscle strength.
• Grip strength and ABSI are stronger predictors of mortality than BMI.
• Integrating grip strength with anthropometric indices like ABSI and BMI may enhance the identification of individuals at risk of mortality.
