Bone density in third trimester: singleton vs. twin pregnancy
Part of Bones, joints & muscles, Hormones & metabolism clinical trials.
This study compares bone density in the third trimester between women pregnant with one baby versus twins. If you qualify, you'll fill out questionnaires and have a quick, non-invasive bone scan to help researchers understand how pregnancy affects bone health.
Summary written for real people, not researchers, by Clin2.
Who can take part

This study looks at simpler ways to measure bone density from routine CT scans of the lower back or abdomen. If you are already getting a CT scan, the researchers will use those images to check your bone health without extra tests or radiation.
This study measures how vitamin D levels change over about 20 days in women. It may help researchers understand vitamin D patterns in pregnancy and different body sizes, which can guide future health recommendations.
This study uses brain scans (MRI) to look at how the brain might be linked to bone health in women with osteoporosis. It compares women with osteoporosis to healthy women of the same age.
This study follows mothers and their twins from the womb through the early days after birth to learn more about twin pregnancies. By joining, you'll help doctors understand how to care for twins and their mothers.
This trial tests a new ultrasound system to see if it can take clear pictures of a single baby during pregnancy. It may help improve care for expecting mothers.
This study uses ultrasound to check the baby's thyroid during pregnancy in mothers who have thyroid problems. It aims to see how the thyroid develops and if any extra care is needed.
