About this study
Official title: Questionnaire for the Assessment of Risk Factors Associated with Endometriosis in Adolescent Women Diagnosed with Endometriosis
A number of risk factors that may be associated with endometriosis in adolescents (medical history and symptoms) are reported in the literature, but no overall estimate of disease risk has been developed.
Providing a tool for assessing risk factors associated with endometriosis in adolescents by estimating disease risk could aid the clinician in diagnosis and reduce diagnostic delay
Read the detailed description
Although more than 60% of adult women with endometriosis report that their painful symptoms appeared before the age of 20, early diagnosis, particularly in adolescent girls, is still a challenge for doctors. The reasons for this delay include inadequate knowledge of the disease among healthcare professionals, the social and health normalisation of menstrual pain, and the peculiar aspects of the disease in adolescent patients. The adolescent patient with endometriosis presents particular anamnestic, familial and personal risk factors, as well as peculiar symptoms such as non-specific abdominal pain, acyclic pelvic pain, gastrointestinal symptoms, migraine, in addition to those classically reported in adulthood.
It may therefore be useful to identify a predictive model of the onset of endometriosis based on the risk factors currently recognised in the literature (anamnestic data) and on the results of a questionnaire to be submitted to adult women (aged between 20 and 50 years), with endometriosis (group 1) and without a diagnosis of endometriosis (group 2), concerning symptoms experienced in adolescence

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Study group | Patients with endometriosis | |
| Control group | Patients without endometriosis |
What is being measured
The primary outcome is the main question the study is designed to answer.

What does the primary outcome measure?
Predictive model of endometriosis onset risk (time frame: During the first visit after enrollment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
