The incidence of Type 1 diabetes among 0-14-year-olds in Australia is very high compared with available data from many other countries. The rate of increase observed globally in the last decade has continued well into this decade in Australia. The rising incidence cannot be explained by changes in genetic susceptibility; there is an urgent need to examine the environmental factors that have contributed to this increase. The findings of this study also have important implications for resource planning.

The results presented herein summarize the most up-to-date cardiovascular statistics available at this time in Australia. The analysis presented here is based on and extends results published in two Australian Institute of Health and Welfare (AIHW) reports, namely Cardiovascular disease: Australian facts 2011 and the cardiovascular disease (CVD) section of Australia's Health 2012. Despite significant improvements in the cardiovascular health of Australians in recent decades, CVD continues to impose a heavy burden on Australians in terms of illness, disability and premature death. Direct health care expenditure for CVD exceeds that for any other disease group. The most recent national data have been analysed to describe patterns and trends in CVD hospitalization and death rates, with additional analysis by Indigenous status, remoteness and socioeconomic group. The incidence of and case-fatality from major coronary events has also been examined. Although CVD death rates have declined steadily in Australia since the late 1960s, CVD still accounts for a larger proportion of deaths (33% in 2009) than any other disease group. Worryingly, the rate at which the coronary heart disease death rate has been falling in recent years has slowed in younger (35-54 years) age groups. Between 1998-99 and 2009-10, the overall rate of hospitalizations for CVD fell by 13%, with declines observed for most major CVDs. In conclusion, CVD disease remains a significant health problem in Australia despite decreasing death and hospitalization rates.

Background/Aim: The ageing population in Australia may contribute to an epidemic of stroke in coming years. We aimed to assess whether deaths and hospitalisations from stroke in Australia are increasing. Methods: Nationwide age- and sex-specific hospitalisation episode data from 1996 to 1997 were used to predict future hospitalisations from stroke. Age- and sex-specific mortality data from 1997 were used to predict future mortality from stroke. These predictions were based on an expected increase in the population’s age and population growth. We compared these estimates to those observed in national figures for the following 9 years. Results: Based on 1996–1997 hospitalisation rates, we calculated that hospitalisations for stroke would be expected to rise from 27,399 to 35,041 in 2005–2006. Using 1997 mortality rates, deaths from stroke would be expected to rise from 9,126 to 12,726 in 2007. Observed hospitalisations (2005–2006) were 6,380 fewer than expected, while deaths (2007) were 4,103 fewer than expected. This represents a 2.21% annual reduction in hospitalisation rate, and a 4.0% annual reduction in mortality rate. Conclusion: Encouragingly, hospitalisation and mortality rates for stroke appear to be declining. If these figures reflect actual occurrences of stroke then it may be that primary and secondary prevention strategies are working.
