Novel and traditional anthropometric measures of obesity association with dynapenia in postmenopausal women.

OBJECTIVES

To examine the association between body mass index (BMI), Body Roundness Index (BRI), and A Body Shape Index (ABSI), with handgrip strength (HGS) and dynapenia in postmenopausal women.

METHODS

This is a cross-sectional study involving 259 postmenopausal women. Age, age at menopause, alcohol consumption, height, weight, waist circumference, and smoking status were recorded. BMI, BRI, and ABSI were separately calculated. Serum creatinine, glucose, glycated hemoglobin, and uric acid were evaluated. HGS was measured using a digital dynamometer, and physical activity was assessed by the International Physical Activity Questionnaire. Student t test, χ2 test, Pearson correlation coefficient, and multivariable linear and logistic regression models were performed for data analysis.

RESULTS

HGS was not correlated with BMI (r=-0.004, P=0.930), BRI (r=-0.080, P=0.190), and ABSI (r=-0.019, P=0.750). The multivariable linear regression models showed that HGS was not significantly associated with BMI (β= 0.01; 95% CI, -0.11 to 0.12), BRI (β= -0.04; 95% CI, -0.34 to 0.25), and ABSI (β= 43; 95% CI, -38 to 124). The multivariable logistic regression models displayed no significant association between dynapenia with BMI (OR= 1.00; 95% CI, 0.92-1.09), BRI (OR= 1.06; 95% CI, 0.84-1.34), and ABSI (OR= 0.80; 95% CI, 0.55-1.14).

CONCLUSIONS

There were no associations between BMI, BRI, and ABSI with HGS. Furthermore, in postmenopausal women, dynapenia was also not associated with these anthropometric indices of obesity.
