Current and historic patterns of chronic disease burden are associated with physical activity and sedentary behavior in older adults: an observational study

Table 4 Comparison of sedentary behavior and physical activity between participants^e with distal vs. recent multimorbidity onset

	Recent onset (< 8 years) N = 105	Distal onset (≥ 8 years) N = 119	Adjusted difference in means Β_{Distal−Recent} (95% CI)^d
Mean Bout Duration (min)^a, mean (SD)	16.6 (6.3)	19.3 (11.0)	2.5 (-0.03, 5.0)
Steps^a, mean (SD)	6025 (3351)	4603 (2506)	-1000 (-1745, -254)*
MVPA (min)^{b, c}, mean (SD)	58 (41)	39 (32)	-12.1 (-21.0, -3.2)*

^a activPAL measures: mean sitting bout duration, daily total steps
^b ActiGraph measure: daily total MVPA
^c MVPA defined using Objective Physical Activity and Cardiovascular Health in older Women (OPACH) cutpoints, which are validated for an older adult population
^d The β_{Distal−Recent} parameter (with 95% CI) corresponds to the estimated model-adjusted difference in means of the given activity measure between participants with distal multimorbidity onset vs. recent multimorbidity onset; model adjusted for age, sex, race/ethnicity, education, BMI, depressive symptoms, and device wear time
^e Among participants with current chronic disease multimorbidity (CCI_current = 2+) and at least 10 years of historical data
Notes: CI = Confidence Interval; PA = Physical Activity; MVPA = Moderate-to-Vigorous Physical Activity
*Statistically significant associations at the p < 0.05 level
