Frailty describes an individual's vulnerability to adverse health outcomes and is a useful construct that assists health professionals to understand the heterogeneity of the ageing population. While the pathophysiological pathways that lead to frailty are not well defined, an individual's sex appears to be a key factor influencing the ageing trajectory. Compared with age-matched men, women tend to have poorer health status (ie, they are more frail) but longer life expectancy (ie, they are more resilient). ⋯ Pharmaceutical and other innovative therapeutic strategies for frailty are highly anticipated. Sex differences in the effectiveness of frailty interventions have not been addressed in the research literature to date. In the future, successful interventions may target many (if not all) biopsychosocial domains, with careful consideration of issues relevant to each sex.

To investigate blood lead levels in an Australian birth cohort of children; to identify factors associated with higher lead levels. ⋯ Blood lead levels in our pre-school children were lower than in previous Australian surveys and recent surveys in areas at risk of higher exposure, and no children had levels above 5 μg/dL. Our findings support advice to manage risks related to exposure to historical lead, especially in older houses.

Differences in stroke risk and cardiovascular mortality for Aboriginal and other Australian patients with atrial fibrillation.
To assess the risks of stroke and cardiovascular mortality for Aboriginal and non-Aboriginal Australians with atrial fibrillation. ⋯ Stroke risk and cardiovascular mortality are markedly higher for Aboriginal than non-Aboriginal patients with atrial fibrillation, particularly for patients under 60. Strategies for providing evidence-based therapies and cardiovascular prevention to Aboriginal people with atrial fibrillation must be improved.

To estimate the proportion of cancer diagnoses in Australia that might reasonably be attributed to overdiagnosis by comparing current and past lifetime risks of cancer. ⋯ About 11 000 cancers in women and 18 000 in men may be overdiagnosed each year. Rates of overdiagnosis need to be reduced and health services should monitor emerging areas of overdiagnosis.
