“…There are studies reporting a change towards higher age in RA patients at disease onset in recent years, which could support the results in this study [23,24]. The higher rate of RF positive women included in the 2000s could be due to their higher age, since the rate of RF positive patients increases with age [25,26] and could also be due to more smokers in that group [27].…”

Abstract:The objective of the study was to compare disease characteristics over the first 5 years of disease in patients with RA, with disease onset in 1990s and 2000s, respectively.Methods: All 2235 patients with early RA (disease duration ≤12 months) were recruited from the BARFOT prospective observational study. These patients were divided into group 1 included 1992 to 1999 (N=1084, 66% women) and group 2 included 2000 to 2006 (N=1151, 69% women). Disease Activity Score (DAS28), VAS pain and Health Assessment Questionnaire (HAQ) were assessed during 5 years. Remission was defined as DAS28 <2.6.Results: At inclusion, both women and men in group 2 had higher mean DAS28 (SD) than group 1, 5.42 (1.22) vs 5.26 (1.19), p=0.004 and 5.28 (1.22) vs 5.00 (1.27), p=0.004, respectively, mainly dependant on pain and not on inflammatory related measures. Over time DAS28 decreased and was in both genders, from 6 months to the 5-year follow-up, significantly lower in group 2. At 5-year, both women and men in group 2 had higher rate of remission than women and men in group 1. However, despite reduction of VAS pain and HAQ there were no differences in pain and HAQ between groups at any time point. Conclusion:Patients included in the 2000s achieved higher frequency of remission at the 5 year follow-up compared with those included in the 1990s, suggested to reflect the more active medical treatment. Interestingly, however, improvement in pain and HAQ did not differ between the two patient cohorts.

“…Conflicting data also exist with regard to secular trends in incidence, with some studies showing a rising incidence (12) and others showing a declining incidence (7,9,13,14). Some authors have reported a shift toward a more elderly age at onset (15,16), but such shifts have not been observed by all (17). Further, given the relatively low prevalence of RA, study populations must be sufficiently large to obtain robust estimates, particularly when stratifying by age and sex.…”

Objective. Epidemiologic assessments of sufficiently large populations are required in order to obtain robust estimates of disease prevalence and incidence, particularly when exploring the influence of various factors (age, sex, calendar time). We undertook this study to describe the epidemiology of rheumatoid arthritis (RA) over the past 15 years.Methods. We used the Ontario Rheumatoid Arthritis administrative Database (ORAD), a validated population-based research database of all Ontarians with RA. The ORAD records were linked with census data to calculate crude and age and sex-standardized prevalence and incidence rates from 1996 to 2010. Vital statistics were used to estimate annual all-cause mortality during the study period.Results Conclusion. Over a 15-year period, we observed an increase in RA prevalence over time. This rise may be attributed to the increasing time to ascertain cases (which may have been latent in the population during earlier years of the study), increasing survival, and/or an increase in the aging background population. Incidence appears to be stable.

“…The occurrence of RA is not static and over the past few decades studies have suggested that the incidence may be decreasing [3,[16][17][18][19][20]. In the light of the changing occurrence of RA, current estimates of the incidence are of general interest to doctors, epidemiologists, and health care planners.…”

Abstract:We estimated the incidence of rheumatoid arthritis in the southern part of Denmark from 1995 to 2001. At a rheumatology hospital serving a population of about 200 000 people over the age of 15, medical records were scrutinized. As case definition we used the tree and list format of 1987 American College of Rheumatology criteria for rheumatoid arthritis. The mean annual incidence rate per 100 000 person years was 40 in females, 21 in males, and 31 in females and males combined. The incidence of rheumatoid arthritis in Denmark is in accordance with recent studies from North America, the UK, and Northern European countries. The aetiology of rheumatoid arthritis is unknown but this study indicates that in these populations the exposure to non-genetic host and environmental aetiological factors is similar.
