The headline finding from our 2003 paper was a 2.5-times increase in the prevalence of obesity since 1980, with 20.8% of Australian adults found to be obese.

AusDiab went on to become a longitudinal study, with the follow-ups of the cohort at 5 and 12 years providing invaluable data for studying obesity, diabetes, prediabetes, hypertension and kidney disease in individuals as they age. The more than 200 papers now published using data from this study have played an important role in influencing national public health policy and action.
