Frequently asked questions

The Genetic variants, Early Life exposures, and Longitudinal Endometriosis symptoms Study (GELLES) is planning to look at a person’s genes and health across their life to find out more about endometriosis. To do this, GELLES needs women both with and without endometriosis to take part.

Endometriosis is a common disease where tissue similar to the lining of the uterus grows outside on other organs causing scarring and pain. Endometriosis may cause painful periods, heavy periods, and pain during sex and when going to the toilet. Some women are so severely affected by the disease that they struggle emotionally and physically with their everyday lives. Research from Women’s Health Australia shows that an estimated 1 in 9 women under the age of 45 in Australia will be diagnosed with endometriosis. This means that you likely know someone with endometriosis.

Very little is known about what causes endometriosis and who might be most at risk of developing the disease. A person’s genes, their family history, and their health and experiences during childhood and adolescence might tell us a lot about who is most likely to get endometriosis. We want to find out more about why endometriosis develops, so that women can be diagnosed earlier and have better treatments.

All women from the 1989-95 cohort of Women’s Health Australia who completed the latest survey in 2019 are being invited to participate in this research. You don’t need to have endometriosis to participate.

If you agree to participate, you will be asked to:

  1. Complete a confidential online survey, which will take approximately 30-60 minutes to complete. The survey includes questions about your health and wellbeing at different points of your life (including medical conditions and pain), your childhood (including questions about your mother’s pregnancy with you, very early childhood, and your relationship with your parents), and your family’s health. It also includes detailed questions about your menstrual cycles, including symptoms you might experience during your period.
  2. Provide a sample of your saliva for genetic analysis. If you consent to providing a saliva sample, you will be mailed a saliva collection kit and instructions.

If you choose to participate by completing the online survey, you are not obligated to provide a saliva sample.

Genes are made up of DNA – the chemical structure carrying your genetic information that determines many human characteristics, such as the colour of your eyes or hair. Researchers study genes in order to understand why some people have a certain condition, such as diabetes or asthma, and why others don’t. Understanding a person’s genes may also explain why some people respond to a treatment or experience a side effect, while others do not.

Participation in this research is entirely your choice. Only those people who give their informed consent will be included in GELLES. Whether or not you decide to participate, your decision will not disadvantage you. Your participation in Women’s Health Australia will not be affected by whether or not you decide to take part in the GELLES substudy.

If you do decide to participate and later change your mind, you can withdraw from GELLES at any time without giving a reason, by contacting Women’s Health Australia on 1800 068 081 (freecall) or emailing us at: alswh@newcastle.edu.au or info@alswh.org.au. You will also have the option to withdraw your data up until data has been provided to researchers for analysis or published.

Everyone who completes the survey by 5:00 pm AEST on Sunday May 29th 2022 will go into the GELLES prize draw, with a chance to win a $1,000 Prezzee Smart eGift Card to be used online or in-store at 100+ Australian retailers. For more details go to: https://www.prezzee.com.au/store/#gift-cards. The eGift cards will be sent via email.

Your contributions will help us to discover more about the possible causes of endometriosis. This is important because health care professionals need ways to diagnose the disease earlier and improve treatment for women.

There’s a small risk that you may find some of the survey questions uncomfortable to answer. If you start to feel uncomfortable or upset at any time, you can choose to end the survey (with the option to return later, if you want to). You can also choose to skip questions that you are uncomfortable answering. If you are feeling distressed, you may also like to discuss your feelings with someone at Lifeline (13 11 14) or 1800 Respect (1800 737 732).

Providing a saliva sample

If you provide a saliva sample, it is possible that someone could trace the coded information in a scientific database back to you and your participation in this study. Even without your name or other identifiers, your genetic information is unique to you (like a fingerprint). We think the risk of this happening is very low.

Participation in the genetic component of GELLES may have an impact on your access to health, disability, or life insurance, if information about your participation, or information collected through your participation becomes part of your medical record. This could happen if you choose to discuss your participation with your doctor. This would place the information in your medical records, an area to which insurance companies routinely have access. Insurance companies may consider participation in this genetic study “high-risk”, believe that it implies there is a family history of a genetic condition. If you are self-employed, or if you apply for a position in which the employer screens employees for health or life insurance purposes, you may have problems with access to health or life insurance. It is also possible you may be refused employment or be terminated from your current employment if the employer’s insurance carrier believes you are a high risk for certain genetic disorders.

Participants in this, or any related studies, cannot claim ownership rights to any medical or scientific product that results from research with their saliva sample. Research results about you as an individual will not be available to you or your GP, nor will it be recorded in your health records.

Lastly, it is possible that the genetic analysis may reveal information that is important for your health care. You can decide whether or not you wish to be contacted if this situation arises.

Your privacy is our number one concern. We have processes and systems in place to protect your privacy:

  • All personal, survey, and genetic information collected for GELLES remains confidential in accordance with the National Health and Medical Research Council (NHMRC) ethical guidelines and the Australian 1988 Privacy Act.
  • Your survey data will be collected using REDCap (an online survey host), with all data securely stored on servers at the Hunter Medical Research Institute in Newcastle, NSW.
  • Your personal details, survey data, and genetic data will all be stored separately.
  • The only link between your personal details and your other data is your participant ID number. Linking your personal details and other data using this number is restricted to authorised members of the Women’s Health Australia research team at the University of Newcastle.
  • All GELLES survey and genetic data about you will be de-identified (i.e., will not contain identifying information, such as your name, address, or date of birth) and stored securely at the University of Queensland.
  • Your data will be combined with the data from many other women before analysis, and findings will only be reported at an aggregate level (i.e., a summary of data from many women). Individual participants will not be identified in any way.
  • Results from this research may be presented in published scientific articles and talks, but your identity will not be revealed.

Survey data: The survey data collected in this study will be linked with the other data held by Women’s Health Australia. As with your regular Women’s Health Australia data, your GELLES data will be securely stored and may be made available for future research. All researchers who wish to use Women’s Health Australia data, including GELLES data, will need to apply to the Australian Longitudinal Study on Women’s Health (ALSWH) Data Access Committee and agree to their terms and conditions for use of the data. Researchers may also need to obtain ethical approval for their project from a Human Research Ethics Committee.

Genetic data: Your saliva sample will be used to extract your DNA and generate genetic information, which may include sequencing your genome. The GELLES research team will analyse your sample and look for regions on the genome related to risk of endometriosis. The analysis of these genetic variants cannot be used for diagnosis right now. However, during the course of this research project, we may discover new information that is important for your health care. You will be asked whether you wish to be contacted if research with your DNA reveals some medical condition relating to your or your family. This may require you to have the test repeated in a clinical laboratory. If you agree, we will contact you if such a situation arises.

Your genetic data will be linked with your survey data and other survey and linked health data held by Women’s Health Australia.

Data from all participants will be pooled and analysed to examine issues related to women’s health and endometriosis. The findings from this study may be reported in publications in scientific journals and in conference presentations and seminars. A summary of results will also be made available in the annual participant newsletter for Women’s Health Australia. Individual participants will not be identified in any reports, publications, or presentations arising from this study.

This information may continue to be valuable to researchers many years into the future, and may be considered for use in future projects. These projects will require approval by the relevant ethics committees before they begin. You will be asked whether you consent to the storage and use of your saliva sample/DNA for future research projects.

Your genetic data (but not your saliva sample) and some of your survey data (but not your name, address, or date of birth) may eventually be put into an international data repository. Information in the repository will only be available to researchers from around the world who are approved to study how genes cause a variety of health conditions.

If you have consented to providing a saliva sample, a saliva collection kit will be mailed to you by the GELLES research team. There is an instruction leaflet included within the kit. You can also find the written instructions online here or watch a short instruction video here.

Once you have provided your sample, following the instructions provided, please place the collection tube in the provided biohazard bag and mail your sample back to us, using the replied paid envelope provided.

Analysis of your DNA may include whole genome sequencing (WGS). The GELLES Research team will analyse a small number of genetic variants that are likely to be associated with endometriosis however, WGS may be performed in subsequent studies if approved by an authorised Human Research Ethics Committee. WGS is a comprehensive method for analysing entire genomes. Genomic information has been instrumental in identifying inherited disorders, characterizing the mutations that drive cancer progression and tracking disease outbreaks. In the future of personalised medicine, whole genome sequence data may be an important tool to guide therapeutic intervention, predicting disease susceptibility and drug response.

This research is not designed to provide any clinical results to participants. The study does not undertake individual analysis of each sample provided, but rather will undertake an overall comparison of genetic markers on all samples provided.

If you have a personal interest in obtaining a genetic test on your DNA, we suggest you consider contacting a genetic testing entity, which can provide such testing. For example, an internet search on ‘DNA testing’ should provide such direction. We recommend that any interpretation of results from a genetic test is done in collaboration with a genetic counsellor.

The analysis we conduct on a person’s saliva sample will not tell us that individual person’s health status, ancestry or predict health outcomes. Researchers will not be looking for these particular genes in their analysis. Rather, they will search for groups of common genes involved in health from a very large group of people. This study will not return any diagnostic genetic information to you or your health professional that may have implications for you or your family. This is standard for this type of research.

Please make sure you have read the participant information statement and that you understand its contents before you consent to participate.
