The patient data reviewed was taken from the Swedish Inpatient Register and the Early Arthritis Register. Using the Swedish Medical Birth Register,You are not allowed to view links.

Linkage to the Medical Birth Register and the Swedish Inpatient Register provided the necessary information on maternal-, pregnancy- and birth-characteristics,You are not allowed to view links.

Researchers from the Karolinska Institute in Sweden found that infants who were hospitalised for infection before their first birthday had an increased likelihood of developing either juvenile idiopathic arthritis (JIA) or adult rheumatoid arthritis (RA) in later life.
However, other parts of the study suggested that perinatal charactertics, such as low birth weight (odds ratio =0.7, 95% confidence interval 0.5-1.0) and the duration of the gestational period may also affect arthritis risk in later life.  A longer gestational period of over 42 weeks,You are not allowed to view links.

The Swedish register-based case-control study reviewed recorded data on individuals born nationwide between 1973 and 2002, and involved 333 RA patients and 3,334 JIA patients. The analysis revealed that an increase in infections within the first 12 months is associated with an increased risk of developing JIA (odds ratio =1.9, 95% confidence interval 1.7-2.1) and sero-negative RA (odds ratio =2.6,You are not allowed to view links.
