Weight Status and Differences in Mobility Performance, Pain Symptoms, and Physical Activity in Older, Knee Osteoarthritis Patients

Table 3

Adjusted means for measures of physical activity among participants of varying weight status (𝑛=79).

Variable	Normal	Overweight	Class I	Class II	Class III
PA^Mod+ (minutes)	113.4^∗±22.1	67.1^#±13.5	53.6±14.3	24.3±14.75	25.3±17.5
Weekly steps	49,505^∗±6,138	34,229^#±3,737	35,763^∧±3,959	22,103±4,096	23,175±4,851
Frequency of exercise bouts >10 minutes of duration	3.16±0.96	1.30±0.58	1.06±0.62	0.89±0.64	0.79±0.76

Values are the mean ± standard error; PA^Mod+ = exercise of moderate or greater intensity. ∗Denotes statistical difference from obese classes I, II, and III for the outcomes. #Denotes statistical difference from obese class II for the outcomes. ∧Denotes statistical difference from obese classes II and III for the outcome.
