Healthy country: Healthy people? Exploring the health benefits of indigenous natural resource management

OBJECTIVE: Decades of health-related research have produced a large body of knowledge describing alarming rates of morbidity, mortality and social/cultural disruption among Indigenous Australians, but have failed to deliver sustainable interventions to arrest the deepening spiral of ill-health. This paper explores the potential of Indigenous natural resource management (NRM) activities to promote and preserve Indigenous health in remote areas of northern Australia. METHOD: A literature review of the health, social science and ecology peer-reviewed journals and secondary literature. CONCLUSIONS AND IMPLICATIONS: Effective interventions in Indigenous health will require trans-disciplinary, holistic approaches that explicitly incorporate Indigenous health beliefs and engage with the social and cultural drivers of health. Aboriginal peoples maintain a strong belief that continued association with and caring for ancestral lands is a key determinant of health. Individual engagement with \u27country\u27 provides opportunities for physical activity and improved diet as well as boosting individual autonomy and self-esteem. Internationally, such culturally congruent health promotion activities have been successful in programs targeting substance abuse and chronic diseases. NRM is fundamental to the maintenance of biodiversity of northern Australia. Increased support for Indigenous involvement in land and sea NRM programs would also deliver concrete social benefits for communities including opportunities for sustainable and culturally apt regional employment, applied education and economic development. NRM may also reinvigorate societal/cultural constructs, increasing collective esteem and social cohesion

Strongylioidiasis: a review of the evidence for Australian practitioners

Objective: To summarise the available evidence concerning the prevalence, clinical manifestations, diagnosis and management of strongyloidiasis in Northern Australia. Methods: We searched Medline, Clinical Evidence and the Cochrane Library using MeSH terms and text words 'strongyloides OR strongyloidiasis'. For Australian studies we included text words '(parasite* OR parasitic OR helminth*) AND Australia*'. We examined references contained in retrieved studies or identified from direct contact with researchers. Studies consistent with our objective that described their methods were eligible for inclusion. Results: The prevalence in some tropical Aboriginal communities is high. Infection can be asymptomatic, cause a range of clinical syndromes or death. It may become chronic. Infected patients are at risk of developing severe disseminated disease particularly with immune compromise. There is little information about the relative frequency of different clinical outcomes. Available diagnostic tools are imperfect. Stool examination has a low sensitivity. Serology may have a low specificity in high prevalence populations and has not been evaluated in Aboriginal populations. Antihelmintic drugs are relatively safe and effective. Community programs based on treatment of stool-positive cases have been associated with a reduced prevalence of strongyloidiasis. We found no studies examining alternative public health interventions. Conclusion: There is a high prevalence in many Aboriginal communities. Strongyloides infection should be excluded prior to commencing immunosuppressive therapies in patients from endemic areas. Further studies examining the public health impact of strongyloidiasis, the role of the enzyme-linked immuno-sorbent assay serological test and population-based approaches to management of the disease in endemically infected Australian populations are needed
