Objective This study explored the risk of antenatal psychosocial distress (APD) and associated potential factors and examined management aspects of risk of APD in women attending Aboriginal primary health care services in Australia. Method Audits of medical records of 797 pregnant women from 36 primary health centres in five jurisdictions (NSW, QLD, SA, WA and NT) were undertaken as part of a quality improvement programme. Information collected included mental health assessed by a standard screening tools, enquiry regarding social and emotional well-being (SEWB), depression management (including antidepressant medications) and referral. Results Around 18% ( n = 141) of women were at risk of APD based on assessment using a standard screening tool or by SEWB enquiry. There was a significant association between risk of distress and women’s life style behaviours (e.g., alcohol, illicit drug use) and health centre characteristics. Of the 141 women, 16% ( n = 22) were prescribed antidepressant drugs during pregnancy. A range of nonpharmaceutical mental health interventions were also recorded, including brief intervention of 61% ( n = 86), counselling of 57% ( n = 80) and cognitive behaviour therapy of 5% ( n = 7). About 39% ( n = 55) of women with APD were referred to external services for consultations with a psychiatrist, psychologist or social worker or to a women’s refuge centre. Conclusions The higher risk of APD associated with women’s life style behaviour indicates that the better understanding of mental health in its cultural context is essential. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: To compare the incidence of first heart failure (HF) hospitalisation, antecedent risk factors and 1-year mortality between Aboriginal and non-Aboriginal populations in Western Australia (2000–2009). Methods: A population-based cohort aged 20–84years comprising Aboriginal (n=1013; mean 54±14years) and non-Aboriginal patients (n=16,366; mean 71±11years) with first HF hospitalisation was evaluated. Age and sex-specific incidence rates and HF antecedents were compared between subpopulations. Regression models were used to examine 30-day and 1-year (in 30-day survivors) mortality. Results: Aboriginal patients were younger, more likely to reside in rural/remote areas (76% vs 23%) and to be women (50.6% vs 41.7%, all p<0.001). Aboriginal (versus non-Aboriginal) HF incidence rates were 11-fold higher in men and 23-fold in women aged 20–39years, declining to about 2-fold in patients aged 70–84years. Ischaemic and rheumatic heart diseases were more common antecedents of HF in younger (<55years) Aboriginal versus non-Aboriginal patients (p<0.001). Hypertension, diabetes, chronic kidney disease, renal failure, chronic obstructive pulmonary disease, and a high Charlson comorbidity index (>=3) were also more prevalent in younger and older Aboriginal patients (p<0.001). Although 30-day mortality was similar in both subpopulations, Aboriginal patients aged <55years had a 1.9 risk-adjusted hazard ratio (HR) for 1-year mortality (p=0.015). Conclusions: Aboriginal people had substantially higher age and sex-specific HF incidence rate and prevalence of HF antecedents than their non-Aboriginal counterparts. HR for 1-year mortality was also significantly worse at younger ages, highlighting the urgent need for enhanced primary and secondary prevention of HF in this population. [Copyright &y& Elsevier]

Abstract: Objectives: To investigate the impact of prevalence correction of population denominators on myocardial infarction (MI) incidence rates, rate ratios, and rate differences in Aboriginal vs. non-Aboriginal Western Australians aged 25–74 years during the study period 2000–2004. Study Design and Setting: Person-based linked hospital and mortality data sets were used to estimate the number of prevalent and first-ever MI cases each year from 2000 to 2004 using a 15-year look-back period. Age-specific and -standardized MI incidence rates were calculated using both prevalence-corrected and -uncorrected population denominators, by sex and Aboriginality. Results: The impact of prevalence correction on rates increased with age, was higher for men than women, and substantially greater for Aboriginal than non-Aboriginal people. Despite the systematic underestimation of incidence, prevalence correction had little impact on the Aboriginal to non-Aboriginal age-standardized rate ratios (6% and 4% underestimate in men and women, respectively), although the impact on rate differences was more marked (12% and 6%, respectively). The percentage underestimate of differentials was greater at older ages. Conclusion: Prevalence correction of denominators, while more accurate, is difficult to apply and may add modestly to the quantification of relative disparities in MI incidence between populations. Absolute incidence disparities using uncorrected denominators may have an error >10%. [Copyright &y& Elsevier]
