The Suggested Formula for Estimating Grip Strength.

Right Hand Grip	2.71 + 11.94 × (gender) + (age) + (hand preference) + (occupation) + 0.25 × HBP + 0.67 × OA − 0.45 × DM+0.11 × height + 0.32 × weight − 0.23 × (waist circumference) (R = 0.85)
Functional constant	(gender) male = 1, female = 0 (age) 10–19 age level = 1.926, 20–29 age level = 3.382, 30–39 age level = 6.004, 40–49 age level = 5.858, 50–59 age level = 4.886, 60–69 age level = 3.484, over 70 age = 0 (hand preference) right hand preference = −0.05, left hand preference = −1.47, ambidexterity = 0 (occupation): heavy = 1.3, medium = −0.001, light = 0 (HBP) HBP = 1, normal = 0; (OA) OA = 1, no OA = 0; (DM) DM = 1, no DM = 0
Left Hand Grip	5.43 + 11.79 × (gender) + (age) + (hand preference) + (occupation) + 0.42 × HBP + 0.474 × OA − 0.937 × DM + 0.091 × height+0.336 × weight − 0.25 × (waist circumference) (R = 0.85)
Functional constant	(gender) male = 1, female = 0 (age) 10–19 age level = 0.916, 20–29 age level = 2.574, 30–39 age level = 5.25, 40–49 age level = 5.281, 50–59 age level = 4.308, 60–69 age level = 2.918, over 70 age = 0 (hand preference) right hand preference = −1.114, left hand preference = 0.589, ambidexterity = 0 (occupation): heavy = 1.25, medium = −0.047, light = 0 (HBP) HBP = 1, normal = 0; (OA) OA = 1, no OA = 0; (DM) DM = 1, no DM = 0
