Read the detailed description

Population: The RDCRN BBD Contact Registry helps researchers identify and recruit patients who are eligible for participation in future research studies. People eligible for enrollment in the RDCRN BBD Contact Registry include patients and parents of patients with Brittle Bone Disorders. All patients with BBD from the United States and around the world are encouraged to join.

Survey Administration: The investigators will administer a review of pregnancy outcomes survey and delineate the outcomes in pregnancies complicated by varying forms of OI. Patients will be sent an email invitation describing the study. If the participant wants to participate and is eligible, she will follow the survey link in the email message, which directs her to an IRB-approved online consent form. A unique survey link will be generated for each participant and included in the survey invitation, which is a customized email message. This link will allow the investigators to determine who completed the survey. The investigators will send repeat email invitations every two months (total of 3 invitations) to those invitees who have not yet participated. The investigators will allow approximately 6 months for enrollment and survey completion and expect that the study will close soon thereafter.

Data: The survey data will be collected and stored at the Rare Diseases Clinical Research Network's Data Management and Coordinating Center (DMCC) at the University of South Florida. All data collected will be sent to the database of Genotypes and Phenotypes (dbGaP) to be stored indefinitely.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pregnancy in OI Assessment

    The goal of this survey is to characterize the course and outcome of pregnancy in individuals with OI. This is a self-report survey that will review pregnancy outcomes (maternal and fetal). Measures of pregnancy outcome will include 1) length of gestation, 2) mode of delivery, 3) neonatal outcomes including birth weight and length, 4) history of back pain or hip pain and or fractures during pregnancy or postpartum 5) number of maternal hospital admissions 6) calcium and vitamin D intake, 7) neonatal complications and 8) OI status in the fetus. One survey will be completed for each gestation (pregnancy).

    Measured: 1 year
