Abstract

Objective: Toexaminemortalityfromallcausesandfromcardiovasculardisease(CVD), and CVD hospitalisation rate for a decentralised Aboriginal community in the Northern Territory. Design and participants: For a community-based cohort of 296 people aged 15 years or older screened in 1995, we reviewed hospital and primary health care records and death certificates for the period up to December 2004 (2800 person-years of follow-up). Mainoutcomemeasures: MortalityfromallcausesandCVD,andhospitalisationwith CVD coded as a primary cause of admission; comparison with prior trends (1988 to 1995) in CVD risk factor prevalence for the community, and with NT-specific Indigenous mortality and hospitalisation rates.

Results: Mortality in the cohort was 964/100 000 person-years, significantly lower than that of the NT Indigenous population (standardised mortality ratio [SMR], 0.62; 95% CI, 0.42–0.89). CVD mortality was 358/100 000 person-years for people aged 25 years or older (SMR, 0.52; 95% CI, 0.23–1.02). Hospitalisation with CVD as a primary cause was 13/1000 person-years for the cohort, compared with 33/1000 person-years for the NT Indigenous population.

Conclusion: Contributors to lower than expected morbidity and mortality are likely to include the nature of primary health care services, which provide regular outreach to outstation communities, as well as the decentralised mode of outstation living (with its attendant benefits for physical activity, diet and limited access to alcohol), and social factors, including connectedness to culture, family and land, and opportunities for self- determination.
