Twin research

Raising the profile of twin designs in research

Twins offer rarely explored advantages for clinical trial and intervention studies. We encourage the growth and development of twin research so we can dissolve research obstacles in the wider research community.

Twin research provides a powerful method of improving research methodology. It optimises resources and reduces costs. We believe twin research must become a well-understood feature of the health and medical researcher’s toolkit.

Our research in twin designs currently explores:

  • intervention studies where a pair of twins are randomly allocated a treatment
  • longitudinal studies featuring twins, which will reach conclusions about our general population and examine issues relevant to twins
  • research that quantifies the role of genetic and environmental causes of variation in disease susceptibility. 

Twins offer special, but rarely explored advantages for clinical trial and intervention studies. Their unique matching for age, sex, genes, physiology, and environment, among other factors,offers us an opportunity to overcome research obstacles that have arisen in other areas.

We provide guidance as to how the unique features of twin designs can help overcome these obstacles and we also conduct valuable research for the twin community.

Our work will empower researchers in Australia, and worldwide, to address major health challenges experienced by the whole population.
