Handgrip Strength and Anthropometry in Parkinson’s Disease at Diagnosis

Table 3

Partial correlations, r value ( value), between age handgrip strength and anthropometrical indices in all patients and controls and for male and female patients separately. Adjustments were done for sex, BMI, PAL, and MNA-total score in controls and adding UPDR-III in patients.


Variables	Patients N = 75	Controls N = 24	Male patients N = 41	Female patients N = 34

HGS, left (kgf)	−0.397 (0.004)	−0.402 (0.088)	−0.352 (0.033)	−0.380 (0.038)
HGS, right (kgf)	−0.398 (0.004)	−0.492 (0.032)	−0.369 (0.025)	−0.290 (0.120)
ECW/ICW ratio	0.408 (0.003)	0.336 (0.160)	0.619 (<0.001)	0.536 (0.002)
TBW	−0.349 (0.013)	−0.515 (0.024)	−0.645 (<0.001)	−0.505 (0.004)
FFMI (kg/m²)	−0.098 (0.502)	−0.039 (0.873)	−0.482 (0.003)	−0.252 (0.178)
FM (%)	0.210 (0.152)	0.052 (0.834)	0.487 (0.002)	0.181 (0.338)

HGS = handgrip strength. ECW = extracellular water. ICW = intracellular water. TBW = total body water (ECW + ICW). FFMI = fat-free mass index (kg/m²). FM (%) = fat mass percent. The significance level is 95% CI ^∗p<0.05.
