2009 Survey on Living with Chronic Diseases, Arthritis Component
aPrevalence estimates (%) and 95 % confidence intervals (95 % CI) are based on weighted data; IADLs Instrumental Activities of Daily Living; bHigh sampling variability (the coefficient of variation is between 16.6 and 33.3 %); Statistically significantly different from those in the oldest age group (75+ years): *p < 0.05; **p < 0.01; ***p < 0.001
