Preterm Birth and Biomarkers for Cardiovascular Disease (BIO-PRETERM)

January 23, 2023 updated by: Uppsala University
Preterm birth is associated with maternal increased risk of cardiovascular disease later in life. In an observational case- control study, investigators want to evaluate whether women with preterm birth have increased levels of biomarkers for cardiovascular disease, to reveal potential pathophysiological mechanisms in common.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Women with spontaneous preterm birth in first pregnancy and a group of matched controls with spontaneous birth in normal time where invited to participate in the study. Participants were identified from the Biobank of Pregnant Women in Uppsala. Levels of cardiovascular biomarkers will be analyzed in plasma samples from the pregnancy and at a follow-up visit where investigators also collect information about other cardiovascular risk factors and lipid status.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

No older than 60 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Women were identified in the Uppsala Biobank of pregnant women at their first pregnancy. Investigators invited women identified as cases or controls to participate by one blood sample and a visit collecting information about cardiovascular risk factors.

Description

Inclusion Criteria:

  • Women identified as cases or controls

Exclusion Criteria:

  • System inflammatory disease
  • Smoking at the time of the pregnancy

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
