Abstract(s)
Grip strength (GS) is an indicator of health and vulnerability and inversely associated with depressive
symptoms. The aim of this study was to explore GS discrimination capacity for depression; and
possible GS cut-of values for depression by sex and age group. Data from 2011 and 2015 on 20,598
(10,416 women) middle-aged and older adults from 14 European countries was analysed. GS was
assessed by dynamometer, and depressive symptoms using the EURO-D scale. GS cut-of values
for depression were calculated and logistic regression models were used to quantify the odds of
having depression in 2011 and in 2015 according to being bellow or above the cut-of value. GS had
a weak discriminant capacity for depression, with the area under the curve varying between 0.54
and 0.60 (p < 0.001). Sensitivity varied between 0.57 and 0.74; specifcity varied between 0.46 and
0.66. GS cut-of values for discriminating depression were 43.5 kg for men and 29.5 kg for women
aged 50–64 years, 39.5 kg for men and 22.5 kg for women aged≥ 65 years. Having GS above the
cut-of represents signifcant lower odds of depression in 2011 and 4 years later, in 2015. Healthcare
practitioners and epidemiologic researchers may consider the low GS cut-of values to screen for
potential depression risk. However, due to its weak discriminant values these cut-ofs should not be
used to identify depression.
