Trial summary

Aim of the project is to validate and functionally characterize the combined impact of candidate genes and stress exposure on drinking in adolescents. Lifetime and recent stress experiences and drinking are recorded in a sample of healthy young adults who are genotyped for polymorphisms in candidate genes related to… Read more about this study

Who may be able to join

  • All 18 or 19 year old participants of the Mannheim risk children study, i.e. a longitudinal birth cohort study that started in 1986 and had the inclusion criteria given below:
  • Male and female singletons, firstborn to their mothers between February 1st, 1986 and February 28th, 1988, consecutively recruited from 2 obstetric and 4 children's hospitals of the Rhine-Neckar region, Germany.
  • with no severe physical handicaps, obvious genetic defects, or metabolic diseases.
  • with German-speaking Caucasian parents.
  • Falling into one of 3 predefined groups with absent, moderate or high pre- and perinatal risk, operationalized by low gestational age at birth, low birth weight, and severity of the following: Preterm labor, EPH-gestosis, perinatal asphyxia, seizures, respiratory distress syndrome, perinatal sepsis.
  • Falling into one of 3 predefined groups with absent, moderate or high psychosocial risk, operationalized by a family risk index measuring the presence of 11 adverse family factors covering characteristics of the parents (e.g., psychiatric disorders), the partnership (e.g., disharmony), and the family environment (e.g., overcrowding)during a period of one year prior to birth.

Who cannot join

  • Intelligence quotient or motor quotient below 70, or presence of severe neurological disorder such as infantile cerebral palsy, at age 15.
  • Women with known pregnancy.

About this study

Aim of the project is to validate and functionally characterize the combined impact of candidate genes and stress exposure on drinking in adolescents. Lifetime and recent stress experiences and drinking are recorded in a sample of healthy young adults who are genotyped for polymorphisms in candidate genes related to alcoholism. All participants undergo a standard laboratory psychosocial stress test. Our hypothesis is that specific genes can be identified which influence drinking by modulating stress response.

Questions about this trial

What is this clinical trial studying?

An observational study of Alcohol Drinking, run by Central Institute of Mental Health, Mannheim at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 May 2007. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00326742, which also lists 2 linked publications.

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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 May 2007.
