aPrevalence ratios and 95 % confidence intervals (95 % CI) are adjusted for sex, body mass index, level of education, type of arthritis, multiple (≥4) painful joints, disease duration, and number of other chronic conditions and are based on weighted data; IADL Instrumental Activities of Daily Living; *p < 0.05; **p < 0.01; ***p < 0.001
