MENTAL HEALTH CONDITIONS IN AUSTRALIAN ABORIGINAL AND TORRES STRAIT ISLANDER (ATSI) INDIVIDUALS - SOCIAL, CULTURAL DETERMINANTS AND PREVENTION STRATEGIES
Australian Aboriginal and Torres Strait Islander (ATSI) are the indigenous population of Australia. Improvement in the state of health in indigenous population has been a challenge in the countries like Australia. It has been observed that social determinants play an important role in population health and health inequity. The important social determinants of health inequality in indigenous population are lack of accessibility to primary health care, poor housing and sanitation, lack of healthy food and safe water. The higher prevalence of mental illness and suicide in the indigenous population of Australia is a reflection of destroyed culture and can be attributed to the social and cultural determinants. Thus, the treatment or management of this mental illness should have a focus on cultural aspects in relation to the family and the society.
Psychological stress, depression and suicide are some of the indicators of mental illness. In a report ―The health and welfare of Australia's Aboriginal and Torres Strait Islander peoples 2015‖, the data regarding the mental health of indigenous population was presented for the year 2012-2013. The percentage of indigenous population who reported depression was found to be 12%, which was higher than the overall percentage of Australians i.e. 9.6%. Indigenous population was found to be 2.7 times more prone to psychological stress than the non-indigenous population. Suicides accounted for 4.8% of the total deaths of indigenous population for the period of 2008-2012. The suicide rate of aboriginal population was twice when compared to remaining Australians. It was 5 times higher in the age group of 15-24 years. (AIHW, 2015) Between 2001 and 2005, the deaths caused due to 'external causes' which include suicides were the second most cause of mortality in aboriginal people of Australia. Indigenous males were considered to be at higher risks for suicides in Australia. The rate was almost twice than the non-indigenous males. (Pink et al., 2008)
The socio-economic risk factors which are responsible for suicides in younger indigenous males are lack of proper education, poverty, lack of access to health care services, residing in remote areas, violence due to race and socioeconomic status, alcohol and illicit substance abuse, lack of employment, etc. Overcrowding and poor quality of housing among the indigenous population has been associated with poor mental health. (AIHW, 2011)
Suicides in aboriginal population are considered as a result of longer periods of trauma which have been passed on by the previous generations to the current ones. It can be put in simple words as aboriginal disempowerment which has lead to suppressed rage. Racism has been considered as the main factor which affects the mental health of indigenous population. (Paradies et al., 2008) Trauma which is a result of multiple stress factors experienced by the aboriginal population may arise from family or the community people. Incidence of cumulative trauma, which is a result of exposure of the individual to a specific determinant such as racism, has been reported in the indigenous population. (Calma, 2009)
The indigenous people who reported high levels of psychological distress were found to be either alcoholics or daily smokers or drug addicts. These people were found to be involved in binge drinking, smoking and drug abuse due to frequent discrimination based on race, socio-economic status and poverty. (ABS, 2010) These patterns of social factors in indigenous females not only affect the mental health of current generation, but also their children in case of pregnant women. Exposure to these risk factors in the uterus, results in poorer mental health status in the foetus, which can progress into their adult life. (Calma, 2008)
Considering all the evidences and the literature surveys the social and cultural risk factors can be identified as follows:
There are many strategies to improve the mental health and reduce the suicides in indigenous population. As the suicidal behaviours and the mental illness are related to the cultural and socioeconomic factors, understanding these factors plays an important role in prevention of these illnesses. Thus, involving the indigenous people in developing the factors that are culturally appropriate and in decision making process is the major goal. One of such strategies is involving the community leader of this population in the knowledge process. This includes delivering the care and knowledge regarding the mental health to the indigenous population through these community persons. They can also be additionally supported by the non-indigenous health professionals to guide the community leader. Communication plays a key role in identifying the mental health conditions of indigenous population. Communicating in the language of these people may have a significantly effective impact on the identification process, thereby treatment and prevention. A randomized study conducted on students has shown that early childhood academic enrichment improves mental health in their lifetime. (Schweihart et al., 2005) Hence, education as a social determinant of health plays a vital role in improving the mental health status in indigenous population. Policies which provide supplemental income can also be a reason for improved mental health in children.
Improvement in the neighbourhood environment such as construction of a park or play ground, maintaining gardens, etc was proved to improve the social well-being of the population. This strategy helps in the coping process i.e. the recreational activities help in overcoming the loss (death or suicide) of the family member and improves the psychological health. Some established evidences identified that the changes in neighbourhood environment were linked to the improvement in the social and mental health. Levels of anxiety and depression were also dropped significantly. (Schweihart et al., 2005) The initiative by the Australian government to reduce the mental illness and the suicidal behaviours in indigenous population was supported by National Suicide Prevention Strategy (NSPS). The strategies to overcome the mental illness and suicides have been based on the two risk factors- immediate and long term.
The ever increasing rates of mental illness and the suicides in the indigenous population of Australia remains a challenge for the government. The cultural and social disparities between the indigenous and non-indigenous population reflects in the rate of suicides of indigenous population which is twice than that of non-indigenous Australians. Hence, there is an urgent need to address these cultural and social factors responsible for mental illness and suicidal behaviours in indigenous Australians. Identifying and addressing these mental health problems in this population can be done by the community helpers in coordination with the physicians and the government, which helps in individual as well as community healing.
