Health and Lifestyle Questionnaire

The Health and Lifestyle Questionnaire was developed for ATR members, and asks about a range of topics including members’ background, health conditions and lifestyle. Invitations to complete the Health & Lifestyle Questionnaire are sent via email to all current ATR members over one year of age where both (or the parents of junior twins) have a valid e-mail address.

The Older Australian Twins Study Amyloid Imaging Project

This important study has been recruiting twins for more than nine years and has made a substantial contribution to understanding brain ageing. The researchers have new funding to take a more in-depth look at how the brain ages by obtaining brain images of ‘plaques’ which contain the amyloid protein - a known predictor of memory decline. While all current participants will be invited to partake in this new phase, the researchers are also keen to recruit new pairs over the age of 65 years from Victoria and NSW.

Sleep quality and back pain

This new study is investigating the value of a sleep quality program in people with low back pain and insomnia. This six-week online study requires adult twins who have completed the Health and Lifestyle Questionnaire, with internet access and a history of low back pain and insomnia to participate (subject to a screening questionnaire).

The Australian Twin Back Pain Study

This 12 month research study is looking at the effects of different types and doses of physical activity on low back pain. Eligibility will be determined by a screening questionnaire for adult twins who have completed the Health and Lifestyle Questionnaire, have internet access, a smartphone and an active email account and where both twins do or do not have low back pain.

You can watch a recent Channel 7 news segment featuring lead researcher Dr Paulo Ferreira, where he discusses his new project – and why twins are so important to the research process.

A Twin Study of the Naplan (National Assessment Program – Literacy and Numeracy)

In this study the researchers are using the results of twins, other multiples, and siblings to help identify the genetic and environmental factors that influence how well a child performs in these tests. This information will be important for developing advice about measures parents and educational authorities can take to help all children reach their full potential in school, and to inform policy-makers about the roles of schools and teachers in children’s rates of academic progress. All twins who have sat the Naplan in the past or will do so in 2015 are eligible.

Why do some people consume excess fat?

Obesity is an important public health issue. It is a condition that can have serious health consequences, including cardiovascular disease, cancer and type-2 diabetes. Researchers from Deakin University are interested in whether genetics play an important role in how much fat one consumes. This study, which is about taste, not weight change, is asking twin pairs to take part in an eight-week program where each twin pair will be randomly placed on either a high or low fat food program. All twins aged 16-years-plus, and able to attend Deakin University Sensory Lab in Melbourne, are eligible to participate.

Type-2 diabetes and brain function

This study is exploring how type-2 diabetes contributes to the risk of dementia. It is open to twin pairs aged 50 years and over, where only one twin has type-2 diabetes.
