The 2012 Moyal Medallist is Professor Annette Dobson, Professor of Biostatistics in the School of Population Health at the University of Queensland.

Title: Statistical Challenges in Longitudinal Epidemiological Studies


Data are collected each three years on about 40,000 women in three age groups who have participated in the Australian Longitudinal Study on Women’s Health since 1996. These data present statistical challenges. Several examples will be discussed.

  • Is it possible to sort out cause and effect when biological and behavioural patterns may have been established before the study began? Is weight gain a precursor or consequence of hysterectomy?
    Does depression exacerbate cigarette smoking, or vice versa?
  • How can population level changes in categorical variables over time be depicted and different patterns of change modelled?
  • How can you reduce bias when estimating population-level health trajectories for older people when many have died or dropped out for health reasons?

The talk is followed by a complimentary light supper in the tearoom on level 4 of E7A. All are welcome.
