Bent, A. (1999). The aim of this descriptive study, undertaken in 1997 was to examine
the prefessional environment and work practices of physiotherapists, occupational
therapists and speech pathologists in public sector positions in Central
Australia. All therapists identified in these positions were interviewed.
The study indicates that incumbents value specific professional benefits
associated with remote area practice, particularly the opportunity to
work with Aboriginal people. However these recruiting advantages are diminished
by a lack of management support - a key factor in the high turnover of
staff. The findings of this study have implications for the development
of strategies to improve support, and thereby retention, of allied health
professionals and other workers in remote areas.
Bridge, C. (1999). Australian Aboriginal women have twice the number of still born babies
as Australian non Aboriginal women and have babies who are five times
more likely to die within the neonatal period. The perinatal mortality
rate is three times higher and the infant mortality is more than five
times the overall rate for babies of Australian Aboriginal women compared
to Australian non Aboriginal women. These are the stark statistics compiled
by the Midwives Notification System in Western Australia (1998). This
paper discusses East Kimberley Aboriginal women and their life cycle.
When compared with women of western culture the life cycle of Aboriginal
women is uniquely different. The lives of traditional Aboriginal people
are encompassed by cultural values and beliefs which determine, govern
and affect who they are, where they belong and how they view the world.
As an Aboriginal women who is conducting the antenatal/postnatal program
in her community, the provision of culturally appropriate health care
is based on these principals and values. Since the authors inception of
this program, evidence suggests that the incidence of Aboriginal women's
representation and first time attendance has increased.
Briganti, E.M., Knight, J.F., Atkins, R.C., & McNeil, J.J. (1999).
This editorial briefly considers the impact of diseases
of the kidneys and urinary tract on the Australian population and identifies
gaps in the current understanding of their epidemiology. The editorial
summarises the key findings of the Australian Kidney Foundation's recently
released national epidemiological survey. It applauds the collection of
detailed epidemiological data on end-stage renal disease (ESRD) but notes
the scarcity of information on the aetiology, incidence and prevalence
of many other renal and urinary tract diseases. The authors conclude that
the Australian Kidney Foundation's survey will provide the evidence necessary
to plan future treatment, prevention and research services. Briscoe, A. (1999). Describes the first ever national male Indigenous health
conference, at which 150 men from across Australia gathered at Ross River
to discuss a range of health and social issues affecting Indigenous men
in the 1990's. Discussion topics included youth suicide, role of Indigenous
men, Indigenous gay mens issues, HIV and family violence. Several key
note speakers from various health centres provided valuable information,
and a number of workshop sessions were also held that enabled participants
to provide input into particular issues. It was finally agreed that Indigenous
men need to take control of their health needs. Other outcomes of the
meeting reflected the need to develop a strategic approach to Indigenous
male health while also beginning to address key needs of Indigenous men.
Butler,T., Spencer, J., Cui, J.S., Vickery, K., Zou, J., & Kaldor,
J. (1999). Objectives: 1. Establish the prevalence of markers for hepatitis B (HBV), C (HCV) and G (HGV) in a sample of male and female inmates. 2. Examine exposure to multiple viruses. 3. Compare risk factors for HGV infection with known risk factors for HBV and HCV. Design: Cross-sectional random sample stratified by sex, age and Aboriginality. Inmates were screened for three hepatitis markers. Participants were 789 inmates (657 male, 132 female) in 27 correctional centres in New South Wales, 1996. Results: Overall detection of each of the three screening markers was 35% for HBV, 39% for HCV and 10% for HGV. Exposure rates were higher in female prisoners than males. Increased rates of anti-HBc were observed in Aboriginal inmates compared with non-Aboriginals (54% cf. 27%); anti-HCV and HGV-RNA were comparable between the two groups (36% cf. 41% and 9% cf. 10%). Markers were significantly higher in female injecting drug users (IDU), particularly HCV (90% cf. 66%). Thirty-five per cent of inmates were unaware of their HCV status. For HBV, 72% did not report past or present exposure despite serological evidence to the contrary. The multivariate analysis identified Aboriginality, long-term injecting and injecting while in prison as risk factors for HBV. HCV risk factors were female sex, non-Aboriginality, institutionalisation and IDU-associated behaviours. For HGV, female sex and previous imprisonment were significant risk factors but IDU was not. Conclusions: Blood-borne hepatitis viruses are common in prison
inmates, particularly females (HBV, HCV and HGV), Aboriginals (HBV) and
IDU (HBV and HCV). Infection can be related to a number of risk factors,
which appear similar for HBV and HCV, but distinct from HGV.
Butler, C., Rissel, C., & Khavarpour, F. (1999). The community's role in maintaining public health by participating in
health service programs is examined. Topics include the government's past
public health policies, the difference between geographical and relational
communities, identifying communities' major health care issues, and the
difficulties in defining community participation.
Carapetis, J. R., Currie, B. (1999). A study was conducted to determine the death rates and
effect on premature mortality in the Northern Territory of acute rheumatic
fever and rheumatic heart disease. Deaths due to acute rheumatic fever
and rheumatic heart disease for the period 1979-1996 were ascertained
from death certificates, a database of all patients with these diseases,
and mortuary records. Of 182 deaths, 171 (94%) were in Aboriginal people.
The mean age at death of Aboriginal people was 35.7 years, compared with
67.3 years in non-Aboriginal people. Premature mortality for Aboriginal
people was more than four times that in developing countries.
Clausen, L. (1999). The article reports differing views on the proposed reduction in liquor
trading hours for the town of Katherine in the Northern Territory. The
proposed model is based on the example of Tennant Creek, a nearby town
which restricted liquor trading hours several years ago. The laws are
encouraged by many people who encounter the effects of the town's extreme
alcohol consumption on a regular basis. Others are sceptical of the ability
of the laws to be effective, claiming alcohol abuse in outback towns is
a deeper, more complex problem. All are greatly concerned about the alcohol-fueled
social problems which are destroying their community.
Colagiuri, S., Miller, J.C.B. (1999). A critical role is proposed for the quantity and quality of dietary
carbohydrate in the pathogenesis of the insulin resistance and hyperinsulinaemia
which characterise the Metabolic Syndrome. We propose that an insulin-resistant
genotype evolved to provide survival and reproductive advantages for the
cold-climate, large- game hunters of the last Ice Age who consumed a low
carbohydrate, high protein diet with periodic starvation. Insulin resistance
would have minimised glucose utilisation by muscles thereby facilitating
the preferential utilisation of glucose by the brain, foetus and mammary
gland. Beginning about 10,000 years ago, following the end of the last
Ice Age and the development of agriculture, dietary carbohydrate increased
and the selection pressure for insulin resistance decreased in some groups.
Agriculture began in the Middle East and spread throughout Europe long
before it was developed elsewhere. Hence the prevalence of the insulin-resistant
genotype decreased in Europeans and other groups exposed to a high carbohydrate
intake for sufficiently long. Some geographically isolated groups such
as the Pima Indians and Nauruans experienced conditions which further
diminished the gene pool diversity and resulted in particularly insulin
resistant populations. Traditional carbohydrate foods have a low glycaemic
index and produce only modest increases in plasma insulin. However, the
constant supply of highly refined high glycaemic index carbohydrate in
modern diets results in postprandial hyperinsulinaemia. The insulin-resistant
genotype is now disadvantageous and predisposes to the development of
the Metabolic Syndrome.
Coory, M. (1999). This letter to the Editor considers the policy implications
for the lack of progress in Indigenous health. While acknowledging the
necessity of accessible health services the letter emphasises the importance
of social and environmental factors and need for appropriate remedies.
The author warns against neglecting these factors simply because they
are hard to change. He also warns against reliance on counselling and
education, citing evidence that indicates that this is not the best approach
for addressing poor health status in economically disadvantaged populations.
Daniel, M., O'Dea, K., Rowley, K.G., McDermott, R., & Kelly, S.
(1999). Background: This study assessed whether glycated haemoglobin
concentration, an indicator of psychogenic stress, differs between Indigenous
populations and non-Indigenous reference groups. Methods: Multivariate and stratified analyses were undertaken
of cross-sectional data from multi-centre community-based diabetes diagnostic
and risk factor screening initiatives in Canada and Australia. Population
groups were Australian Aborigines (n = 116), Torres Strait Islanders (n
= 156), Native Canadians (n = 155), Greek migrants to Australia (n = 117),
and Caucasian Australians (n = 67). Measurements included fasting glycated
haemoglobin (HbA(1c)) concentration, fasting and 2 hour post-load glucose
concentrations, body mass index, waist-to-hip ratio, and demographic variables.
Results: Mean HbA(1c) concentrations were greater for Indigenous
groups than for Greek migrants and Caucasian Australians (P < 0.0001).
The covariate adjusted Indigenous versus non-Indigenous difference (95%
CI) was 0.90 (0.58-1.22) percentage units, 18.2% higher for Indigenous
people, Stratified analyses indicated greater HbA(1c) for Indigenous than
for non-Indigenous persons with normoglycaemia (P = 0.009), impaired glucose
tolerance (P = 0.097), and diabetes (P < 0.0001) Conclusions: HbA(1c) concentrations are greater for Indigenous
than for non-Indigenous groups. Social changes, low control, and living
conditions associated with westernisation may be inherently stressful
at the biological level for Indigenous populations in westernised countries.
Eades, S. (2000).
Franks, C., Ewald, D. (1999). This article discusses an investigation into an outbreak
of gastroenteritis among visitors to a remote central Australian Aboriginal
community. After describing how the Public Health Service went about their
investigation, it then discusses the importance of operating within a
culturally appropriate manner and the implications of investigations that
do not return perceived value to the community. The point is made that
with any investigation of a community, social disruption will occur and
a decision must be made as to whether the benefits of the findings outweigh
the costs in terms of the goodwill and relationships between investigators
and the Aboriginal community. It goes on to suggest guidelines for investigations
of future outbreaks in central Australian Aboriginal communities which
include: clarifying community commitment, weighing up the costs and benefits
of the investigation, negotiating a time to visit, working directly with
an Aboriginal health worker, giving prompt and appropriate feedback and
providing encouragement and further assistance if required.

Laming, A.C., Currie, B.J., DiFrancesco, M., Taylor,
H.R. & Mathews, J.D. (2000). Objective: To evaluate the impact of treating children with acute trachoma and their contacts with oral azithromycin. Design: Open, uncontrolled, prospective evaluation of a community-based treatment strategy. Setting: Central Australian semi-desert Aboriginal community (1995-1996). Participants: 216 school- and pre-school children aged 6 months and up to 15 years. Intervention: All children with acute trachoma and their contacts (co-resident siblings aged between 6 months and 15 years) received single-dose oral azithromycin suspension (20mg/kg, to a maximum of 1000 mg). Main Outcome measure: Prevalence of acute trachoma (World Health Organisation trachoma diagnostic criteria). Results: Trachoma prevalence at baseline was 42% (71/169) and 55% (18/33) for school children and preschool children, comprising 77 with follicular trachoma and their 47 contacts, were treated with azithromycin over an 8-week period. Acute trachoma prevalence in school children fell to 22% at 6-8 months (P<0.0001) and was 31% at 12 months (P<0.05 compared with baseline). Pre-school children were followed up for 6 months after treatment, and their trachoma prevalence fell from 55% to 25% (P<0.05). Further treatment was given to children with trachoma at 12 months, and the point prevalence of trachoma for school children at 24 months was 34%. Conclusion: In contrast to mass-treatment strategies,
significant reductions in trachoma prevalence at 6 months were achieved
by screening 35% of community members (216) and treating 20% (124). The
subsequent prevalence support the need for more comprehensive treatment
programs, including health promotion efforts and to improve living conditions.
Leach, A.J. (1999). Remote and rural Australian Aboriginal children achieve lower standards
of numeracy and literacy than their non-Aboriginal peers. The reasons
are complex, but extraordinarily high rates of conductive hearing loss
(>50%) are, in part, responsible for poor classroom success. In addition
to the burden of acute bacterial respiratory illness (highest rates of
invasive pneumococcal disease in the literature), chronic disease affects
virtually every young child. In the Aboriginal community studied, otitis
media commenced within 3 months of birth for all infants, progressed to
chronic suppurative otitis media in 60% and did not resolve throughout
early childhood. Our findings, supported by mathematical modelling, show
that the vicious cycle of endemic chronic otitis media is perpetuated
by high carriage rates of multiple species and multiple types of respiratory
bacterial pathogens, by high cross-infection rates, and thus, by early
age of pathogen acquisition and prolonged carriage. Long-term damage to
respiratory mucosa, possibly linked to later chronic bronchitis and bronchiectasis,
follows a constant series of infections by each of the concurrently held
pathogens, without periods of recovery. Overcrowding and poor hygiene
promote this vicious cycle. Medical and social options for intervention
are limited by poor resources, low expectations for health and a complex
biology that includes antibiotic resistant pneumococci.
McCaughan, G.W., & Torzillo, P.J. (2000).
McDermott, R. (1999). Wide differentials continue to exist in mortality rates and other health
outcomes between Aboriginal and non-Aboriginal Australians. In the Northern
Territory (NT), where Aborigines make up 24% of the population, the all-causes
age-adjusted standardised mortality ratio for Aborigines compared with
non-Aborigines has remained above 3 since the late 1970s, with significant
regional variations. During 1995 an expenditure analysis was undertaken
for primary health care (PHC) services in different regions of the NT
and compared withmortality ratios. At the same time, a method for needs-based
funding was being developed which could replace the existing historical
funding arrangements. In the first instance, the application of a simplified
version of this Resource Allocation Formula (RAF) resulted in a significant
shift of resources for new prevention program funding to regions of relatively
high mortality and low per capita PHC expenditure. However, developing
RAFs to redistribute at the margin within the NT is likely to generate
further inequities between NT programs and counterparts in other states.
If outcomes-based resource allocation is to be meaningful nationally,
the reference point for the RAF should be national average PHC expenditure
rather than existing state averages. There is a need for a combined approach
to outcomes-based planning which takes into account both the equity arguments
of resource allocation models and efficiency arguments to maximise health
gains. Some of these arguments are explored in this paper.

McLean, M.J., Condon, J.R. (1999). A process evaluation of the Northern Territory (Australia) mammography
program, NT Breast Screen (NTBS), during its initial 18 months of operation
is described. During this time, 2,882 screening mammograms were performed;
98 women were recalled for assessment (3.4%). The program was well accepted
by clients and general practitioners. NTBS faced challenges because of
its small and dispersed population, a lack of local radiologists with
mammographic experience and the conflict with other pressing health issues,
particularly in Aboriginal health. Despite these challenges, the program
functioned effectively during its initial 18 months.
Omeri, A., Ahern, M. (1999). This article reviews the literature pertaining to the recruitment
and retention of Indigenous students in undergraduate nursing programs.
It notes the significant role that Aboriginal and Torres Strait Islander
nurses may play in efforts to improve the health and wellbeing of Indigenous
people but expresses concern at their scarce numbers. The article considers
the factors that influence the low numbers of Indigenous nursing students
at Australian universities and makes recommendations for change. To improve
the recruitment and retention of Indigenous nurses the authors propose
a number of culturally meaningful strategies that address curriculum design
and faculty education in transcultural nursing.
Patterson, K.M., Holman, C.D.J., English, D.R., Hulse,
G.K., & Unwin, E. (1999). Some 10,533 first admissions among 16,294 total admissions mentioning
any of 19 groups of illicit drug problems were identified using linked
hospital separation data from the WA Health Services Research Linked Database.
The objective was to monitor incidence rates of first-time hospital admission
with an illicit drug problem in the Indigenous and non-Indigenous populations
of Western Australia in 1980-1995. Trends in age-standardisation rates
showed two distinct features: a rapid acceleration in first-time admission
rates commencing from about 1991; and a cross-over of the rates in Indigenous
and non-Indigenous people. The results are consistent with data on the
rising use in injectable amphetamines and other illicit drugs especially
among Aboriginal people.

Objective: To document the frequency and disease phenotype of various rheumatic diseases in the Australian Aborigine. Methods: A comprehensive review was performed of the archaeological, ethnohistorical and contemporary literature relating to rheumatic disease in these Indigenous people. Results: No evidence was found to suggest that rheumatoid arthritis (RA), ankylosing spondylitis (AS), or gout occurred in Aborigines before or during the early stages of white settlement of Australia. Part of the explanation for the absence of these disorders in this indigenous group may relate t the scarcity of predisposing genetic elements, for example, shared rheumatoid epitope for RA, B27 antigen for AS. In contrast, osteoarthritis appeared to be common particularly involving the temporomandibular joint, right elbow and knees and most probably was related to excessive loading in their hunter gatherer lifestyle. Since white settlement, high frequency rates for rheumatic, systemic lupus erythematosus, and pyogenic arthritis have been observed and there are now scanty reports of the emergence of RA and gout in these original Australians. Conclusion: The occurrence and phenotype of various
rheumatic disorders in Australian Aborigines is distinctive but with recent
changes in diet, lifestyle, and continuing genetic admixture may be undergoing
change. An examination of rheumatic disease in Australian Aborigines and
its changing phenotype may lead to a greater understanding of the aetiopathogenesis
of these disorders.
Tonkin, A.M., Bennett, S. (1999). Mortality from cardiovascular diseases has dropped 64% in Australia
since the 1960s, yet cardiovascular deaths still make up 41% of all deaths.
The prevalence of overweight, smoking, inactivity, and other preventable
risk factors for heart and blood vessel disease remains very high. Among
Indigenous Australians, the death rate from cardiovascular diseases is
nearly twice that in the general population. Lifestyle modification, specific
therapy, and risk factor assessment must all be included in prevention
programs.
Wake, D., Martin, K., & Dineen, J. (1999). This article describes the various traditional mourning
practices adhered to by central and northern Australian Indigenous people
before and after the death of a loved one. The authors note the misunderstandings
that can arise between Western health care professionals and grieving
Indigenous people. They recommend that the Western health care system
adopt a liberal attitude and show compassion and respect for the rituals
of Indigenous Australians.
Walton, S.F., Choy, J.L., Bonson, A., Valle, A., McBroom, J., Taplin,
D., Arlian, L., Mathews, J.D., & Currie, B. (1999). Overcrowding is a significant factor contributing to endemic infection
with Sarcoptes scabiei in human and animal populations. However,
since scabies mites from different host species are indistinguishable
morphologically, it is unclear whether people can be infected from scabies-infested
animals. Molecular fingerprinting was done using three S. scabiei-specific
single locus hypervariable microsatellite markers, with a combined total
of 70 known alleles. Multilocus analysis of 712 scabies mites from human
and dog hosts in Ohio, Panama and Aboriginal communities in northern Australia
now shows that genotypes of dog-derived and human-derived scabies cluster
by host species rather than by geographic location. Because of the apparent
genetic separation between human scabies and dog scabies, control programs
for human scabies in endemic areas do not require resources directed against
zoonotic infection from dogs.
White, A. (1999). This article is written by a first year graduate medical student at the
University of Queensland who focused on the Aboriginal community of Yarrabah
for a one month elective unit. His work involved research as well as practical
experience within the community. As a result of this experience, the student
has realised that health is a culturally relative term, and health issues
may be different for Indigenous Australians. He concludes with two points
which he believes should be central to the aim of raising the health profile
of Indigenous Australians, ie to have a sense of pride and identity, and
for health workers to understand the great diversity of Indigenous people
within Australia. He also points out that without first hand experience,
it is very difficult to realise how crucial social change is as a precursor
to change in health status. |
