Are you pregnant and living with arthritis? You can help advance critical research by joining the Arthritis Pregnancy Study—a remote, observational study. This means we only collect information; you’ll never be asked to take or change any medication. With over 20 years of experience, MotherToBaby Pregnancy Studies conducts research to provide essential information that helps pregnant women and their healthcare providers make informed decisions about treating chronic health conditions during pregnancy.

- At-home convenience: All participation is done virtually through phone interviews—no travel or in-person visits required.
- Your experience matters: Contribute to research that tries to understand if arthritis and its treatments impact pregnancy outcomes.
- Secure and confidential: Your information is protected, and participation fits seamlessly into your daily routine.
Who Can Join?
Pregnant women diagnosed with ankylosing spondylitis (AS), non-radiographic axial spondyloarthritis (nr-axSpA), hidradenitis suppurativa (HS), lupus (SLE or lupus nephritis), psoriatic arthritis (PsA), or other chronic inflammatory and rheumatic conditions.
