Variations in physical activity and sedentary behavior during and after hospitalization in acutely admitted older medical patients: a longitudinal study

Table 2 Number of steps, time spent in uptime and sedentary behavior during the three periods.

Test time:	Patients (N)	Steps (number per day)	Uptime (hours per day)	Sedentary behavior (hours per day)
Hospitalization	48	728 (IQR: 176;2089)	1.7 h (IQR: 1.0;2.8)	21.4 h (IQR: 20.7;22.4)
Discharge	49	2207 (IQR: 1433;3148)	4.0 h (IQR: 2.7;5.4)	19.5 h (IQR: 18.1;21.0)
Four weeks after discharge	43	2622(IQR: 1714;3865)	4.0 h (IQR: 2.8;5.8)	19.6 h (IQR: 18.0;20.8)
Change from hospitalization to discharge		204 % [CI: 149 ;271%] *	1.87 h [CI: 1.5;2.24] *	-1.89 h [CI: - 2.28; -1.50] *
DEMMI > 62	28	172 % [CI: 108; 257 %] *	1.02 h [CI: 0.83;1.22] *	-1,23 h [CI: -1.80; -0.67] *
DEMMI ≤ 62	37	242 % [CI: 157; 353 %] *	2.86 h [CI: 2-43;3.29] *	-3.10 h [CI: -3.60; -2,58] *
Change from discharge to four weeks after		28 % [CI: 10 %; 50 %] **	0.57 h [CI: 0.28;0.87] **	-0.48 h [CI: -0.79; -0,67] **
DEMMI > 62	28	62 % [CI: 34; 96 %] **	0.23 h [CI: 0.09;0.37] **	-0.69 h [CI: -1.11; -0.27] **
DEMMI ≤ 62	37	-2 % [CI: -24; 26 %]	0.28 h [CI: -0.08;0.65]	-0.09 h [CI: -0.50; -0.33] **

Table 2: Results for daily number of steps, time spent in uptime and sedentary behavior during hospitalization, after discharge and four weeks after discharge. The results for taken number of steps and time (h) spent in uptime/sedentary are expressed as medians with first and third quartile. Changes between test times are expressed as means with 95% Confidence interval (CI). relative changes are expressed as percentage for steps and absolute changes for uptime and sedentary behavior; * p<0.0001 for the difference between baseline (hospitalization) and discharge;** p<0.01 for the difference between discharge (baseline) and four weeks after discharge.
