The Australian Longitudinal Study on Women's Health (ALSWH) is one of the most comprehensive health studies in Australia and has helped improve health services for Australian women.

ALSWH assesses women's physical and mental health, as well as psychosocial aspects of health (such as socio-demographic and lifestyle factors) and their use of health services. Since its inception ALSWH has provided invaluable data about the health of women across the lifespan, and informed federal and state government policies across a wide range of issues.

This longitudinal study has surveyed over 40,000 women in three cohorts who were aged 18-23, 45-50 and 70-75 when surveys began in 1996. They are now recruiting a new age group of young women aged 18-23 in 2013.

Participants are asked to complete a short online survey about their health and lifestyle once a year.

As an incentive women who complete the survey go in the draw to win one of 100 prizes valued at $50 each.

The Australian Longitudinal Study on Women's Health is funded by the Australian Government Department of Health and Ageing and is a collaborative project conducted by staff and investigators at The University of Newcastle and The University of Queensland. It is scheduled to continue until at least 2016.
