The associations between basic psychological need satisfaction at work and the wellbeing of Indigenous and non-Indigenous employees.

We investigated how satisfaction of the basic psychological needs at work was associated with the psychological and physical wellbeing of Indigenous and non-Indigenous employees both within and outside of the workplace. Participants included 1,146 Indigenous (n = 559) and non-Indigenous Australians (60.9% female), aged 18 to 81 years (Mage = 43.54) who were recruited through their employer or online advertisements. Structural equation modelling (SEM) was used to analyse the data, and Indigenous status and occupation type were investigated as moderators. Results revealed that independent of income, autonomy satisfaction was related to better physical and psychological health, satisfaction of the need for relatedness was associated with increased family and community thriving, and competence satisfaction was linked to decreased psychological distress. Results also showed that autonomy, competence, and relatedness need satisfaction was lower among Indigenous employees compared to non-Indigenous employees. Moderation analyses suggested that relatedness at work was especially important for non-Indigenous employees' connection with their community, as were high levels of competence satisfaction for Indigenous employees. These findings are discussed in the context of self-determination theory and the implications for organizations wanting to improve the wellbeing of their Indigenous and non-Indigenous workforce.

Role of maternal age at birth in child development among Indigenous and non-Indigenous Australian children in their first school year: a population-based cohort study.

BACKGROUND: Indigenous Australian children are twice as likely to score poorly on developmental outcomes at age 5 years than their non-Indigenous peers. Indigenous children are also more likely to be born to younger mothers. We aimed to quantify the relationship between maternal age at childbirth and early childhood development outcomes in Indigenous and non-Indigenous children. METHODS: In this population-based, retrospective cohort study, we used data from the Australian Early Development Census (AEDC) that were probabilistically linked by the New South Wales (NSW) Centre for Health Record Linkage to several NSW administrative datasets, including the Perinatal Data Collection, the Register of Births, Deaths and Marriages (for birth registrations), the Admitted Patient Data Collection, and public school enrolment records, as part of the Seeding Success study. The resulting data resource comprises a cohort of 166 278 children born in NSW whose first year of school was reported in a 2009 or 2012 AEDC record (which were the years of AEDC data available at the time of data linkage). The primary outcome was the aggregate outcome of developmental vulnerability (scores in the bottom decile, according to the 2009 benchmark, on one or more of the five AEDC domains, which include physical, social, emotional, language and cognitive, and communication development). This outcome was measured in singleton children without special needs recorded on the AEDC, in those with available developmental data. As a secondary outcome analysis, we also repeated the main analyses on the outcome of developmental vulnerability on the individual domains. We estimated the absolute risk of developmental vulnerability by maternal age in Indigenous and non-Indigenous populations, and we also estimated the risk difference and relative risk between Indigenous and non-Indigenous children by use of modified Poisson regression. FINDINGS: Of 166 278 children in the cohort, 107 666 (64·8%) children were enrolled in a public school in NSW in 2009 or 2012, of whom 7994 (7·4%) children were Indigenous (ie, they, or either parent, were recorded as Aboriginal or Torres Strait Islander on one or more birth records) and 99 672 (92·6%) children were not Indigenous. After exclusions, the final study population included 99 530 children (7206 [7·2%] Indigenous and 92 324 [92·8%] non-Indigenous). Of those for whom developmental outcome data were available, 2581 (35·9%) of 7180 Indigenous children and 18 071 (19·7%) of 91 835 non-Indigenous children were developmentally vulnerable on one domain or more. The risk of developmental vulnerability decreased with maternal ages between 15 and 39 years, but the decrease in risk with maternal age was significantly steeper in non-Indigenous than Indigenous children. INTERPRETATION: Developmental vulnerability is most common in Indigenous and non-Indigenous children born to young mothers; however, Indigenous children have an increased risk of this outcome across most of the maternal age range. Policies that improve the socioeconomic circumstances of Indigenous children and families could promote better developmental outcomes among Indigenous children. Culturally appropriate support for Indigenous children, including those born to young mothers and disadvantaged families, could also reduce early childhood developmental inequalities.

"I Had a Little Bit of a Bloke Meltdown But the Next Day, I Was Up": Understanding Cancer Experiences Among Aboriginal Men.

BACKGROUND: Although cancer in indigenous populations is receiving increased research attention, there is a gap in understanding the particular experiences of Aboriginal men. OBJECTIVE: The aim of this study is to integrate a range of primary and secondary accounts of the experiences of Aboriginal men in engaging with a cancer diagnosis and treatment in Australia. METHODS: Secondary analysis of qualitative interviews (n = 54) conducted between 2008 and 2011 revealed recurrent themes regarding the cancer experiences of Aboriginal men in a subset of participant interviews (n = 23). The analysis reports themes that spanned the accounts of Aboriginal men with cancer (n = 6) and those of their carers (n = 12) and clinicians (n = 5). RESULTS: Recurrent beliefs about the cancer experiences of Aboriginal men included that they "avoid seeking help" for health matters, including cancer symptoms, and to "get on with it," "not talk about it," and "manage without fuss" after a cancer diagnosis. Although some men described having to "accept vulnerability," emphasis was placed on appreciating men's desire to "protect cultural roles" and "connect with family and culture" throughout care and treatment, including through humor. CONCLUSIONS: Men's accounts of the experiences of cancer diagnosis and care reveal more than simply individual challenge, extending to encompass the very real social and economic implications of illness and vulnerability for Aboriginal men today. IMPLICATIONS FOR PRACTICE: Aboriginal men could be better engaged with cancer diagnosis and treatment if greater attention was paid to recognizing preferred approaches, including pragmatism and humor, and supporting connections to family and culture throughout the cancer journey.

Lung cancer treatment and mortality for Aboriginal people in New South Wales, Australia: results from a population-based record linkage study and medical record audit.

BACKGROUND: The aim of this study was to compare surgical treatment received by Aboriginal and non-Aboriginal people with non-small cell lung cancer (NSCLC) in New South Wales (NSW), Australia and to examine whether patient and disease characteristics are associated with any disparities found. An additional objective was to describe the adjuvant treatments received by Aboriginal people diagnosed with NSCLC in NSW. Finally, we compared the risk of death from NSCLC for Aboriginal and non-Aboriginal people. METHODS: We used logistic regression and competing risks regression to analyse population-based cancer registry records for people diagnosed with NSCLC in NSW, 2001-2007, linked to hospital inpatient episodes and deaths. We also analysed treatment patterns from a medical record audit for 170 Aboriginal people diagnosed with NSCLC in NSW, 2000-2010. RESULTS: Of 20,154 people diagnosed with primary lung cancer, 341 (1.7%) were Aboriginal. Larger proportions of Aboriginal people were younger, female, living outside major cities or in areas of greater socioeconomic disadvantage, smoking at the time of diagnosis and had comorbidities. Although Aboriginal people were, on average, younger at diagnosis with non-metastatic NSCLC than non-Aboriginal people, only 30.8% of Aboriginal people received surgery, compared with 39.5% of non-Aboriginal people. Further, Aboriginal people who were not receiving surgery, at the time of diagnosis, were more likely to be younger, live in major cities and have no comorbidities. The observed risk of death from NSCLC 5 years after diagnosis was higher for 266 Aboriginal people (83.3% 95% CI 77.5-87.7) than for 15,491 non-Aboriginal people (77.6% 95% CI 76.9-78.3) and the adjusted subhazard ratio was 1.32 (95% CI 1.14-1.52). From the medical record audit, 29% of Aboriginal people with NSCLC had potentially curative treatment, 45% had palliative radiotherapy/chemotherapy and 26% had no active treatment. CONCLUSIONS: There are disparities in NSCLC surgical treatment and mortality for Aboriginal people compared with non-Aboriginal people in NSW. It is imperative that Aboriginal people are offered active lung cancer treatment, particularly those who are younger and without comorbidities and are therefore most likely to benefit, and are provided with assistance to access it if required.

Comparing colorectal cancer treatment and survival for Aboriginal and non-Aboriginal people in New South Wales.

OBJECTIVES: Our aim was to compare surgical treatment rates and survival rates for Aboriginal and non-Aboriginal people in New South Wales with colorectal cancer, and to describe the medical treatment received by a sample of Aboriginal people with colorectal cancer. DESIGN, SETTING AND PARTICIPANTS: All people diagnosed with colorectal cancer in NSW during 2001-2007 were identified and their cancer registry records linked to hospital admissions data and death records. A medical records audit of a sample of Aboriginal people diagnosed with colorectal cancer during 2000-2011 was also conducted. MAIN OUTCOME MEASURES: Cause-specific survival, odds of surgical treatment, and the proportions of people receiving adjuvant treatments. RESULTS: Of 29 777 eligible colorectal cancer cases, 278 (0.9%) involved Aboriginal people. Similar proportions of Aboriginal (76%) and non-Aboriginal (79%) people had undergone surgical treatment. Colorectal cancer-specific survival was similar for Aboriginal and non-Aboriginal people up to 18 months after diagnosis, but 5 years post-diagnosis the risk of death for Aboriginal people who had had surgical treatment was 68% higher than for non-Aboriginal people (adjusted hazards ratio, 1.68; 95% CI, 1.32-2.09). Of 145 Aboriginal people with colorectal cancer identified by the medical records audit, 117 (81%) had undergone surgery, and 56 (48%) had also received adjuvant chemotherapy and/or radiotherapy. CONCLUSIONS: Aboriginal people with colorectal cancer had poorer survival rates than non-Aboriginal people, although rates of surgical treatment, complications and follow-up colonoscopy were similar. More work is needed to identify and understand why outcomes for Aboriginal people with colorectal cancer are different from those of other New South Wales residents.

Are Aboriginal people more likely to be diagnosed with more advanced cancer?

OBJECTIVE: To determine whether Aboriginal people in New South Wales were diagnosed with more advanced cancer than non-Aboriginal people. DESIGN, SETTING AND PARTICIPANTS: Cross-sectional study of cancer cases, excluding lymphohaematopoietic cancers and cancers of unknown primary site, diagnosed in NSW in 2001-2007. MAIN OUTCOME MEASURE: Spread of disease at time of cancer diagnosis. RESULTS: Overall, 40.3% of 2039 cancers in Aboriginal people and 46.6% of 191 954 cancers in non-Aboriginal people were localised at diagnosis. After adjusting for age, sex, year of diagnosis, area of residence and socioeconomic status, Aboriginal people had significantly higher risks of regional or distant spread for head and neck cancer, relative to localised spread, than non-Aboriginal people (regional: adjusted relative risk ratio [RRR], 1.89; 95% CI, 1.21-2.98; distant: adjusted RRR, 3.40; 95% CI, 1.85-6.05; P < 0.001). For breast, cervical and prostate cancers and melanoma, the risks of regional or distant spread were higher for Aboriginal people, but these differences were not statistically significant. For lung, colorectal, upper gastrointestinal tract, other gynaecological, and eye, brain and central nervous system cancers, the risks of regional, distant and unknown spread of cancer were similar for Aboriginal and non-Aboriginal people. CONCLUSION: Aboriginal people were more likely than non-Aboriginal people to be diagnosed with more advanced cancer for only a few cancer types, most notably head and neck cancers. Differences in spread of disease at diagnosis are unlikely to explain much of the survival differences observed across a wide range of cancers between Aboriginal and non-Aboriginal people in NSW.

Prostate cancer mortality outcomes and patterns of primary treatment for Aboriginal men in New South Wales, Australia.

OBJECTIVE: To compare prostate cancer mortality for Aboriginal and non-Aboriginal men and to describe prostate cancer treatments received by Aboriginal men. PATIENTS AND METHODS: We analysed cancer registry records for all men diagnosed with prostate cancer in New South Wales (NSW) in 2001-2007 linked to hospital inpatient episodes and deaths. More detailed information on androgen-deprivation therapy and radiotherapy was obtained from medical records for 87 NSW Aboriginal men diagnosed in 2000-2011. The main outcomes were primary treatment for, and death from, prostate cancer. Analysis included Cox proportional hazards regression and logistic regression. RESULTS: There were 259 Aboriginal men among 35,214 prostate cancer cases diagnosed in 2001-2007. Age and spread of disease at diagnosis were similar for Aboriginal and non-Aboriginal men. Prostate cancer mortality 5 years after diagnosis was higher for Aboriginal men (17.5%, 95% confidence interval (CI) 12.4-23.3) than non-Aboriginal men (11.4%, 95% CI 11.0-11.8). Aboriginal men were 49% more likely to die from prostate cancer (hazard ratio 1.49, 95% CI 1.07-1.99) after adjusting for differences in demographic factors, stage at diagnosis, health access and comorbidities. Aboriginal men were less likely to have a prostatectomy for localised or regional cancer than non-Aboriginal men (adjusted odds ratio 0.60, 95% CI 0.40-0.91). Of 87 Aboriginal men with full staging and treatment information, 60% were diagnosed with localised disease. Of these, 38% had a prostatectomy (± radiotherapy), 29% had radiotherapy only and 33% had neither. CONCLUSION: More research is required to explain differences in treatment and mortality for Aboriginal men with prostate cancer compared with non-Aboriginal men. In the meantime, ongoing monitoring and efforts are needed to ensure Aboriginal men have equitable access to best care.

Increasing rates of surgical treatment and preventing comorbidities may increase breast cancer survival for Aboriginal women.

BACKGROUND: Lower breast cancer survival has been reported for Australian Aboriginal women compared to non-Aboriginal women, however the reasons for this disparity have not been fully explored. We compared the surgical treatment and survival of Aboriginal and non-Aboriginal women diagnosed with breast cancer in New South Wales (NSW), Australia. METHODS: We analysed NSW cancer registry records of breast cancers diagnosed in 2001-2007, linked to hospital inpatient episodes and deaths. We used unconditional logistic regression to compare the odds of Aboriginal and non-Aboriginal women receiving surgical treatment. Breast cancer-specific survival was examined using cumulative mortality curves and Cox proportional hazards regression models. RESULTS: Of the 27 850 eligible women, 288 (1.03%) identified as Aboriginal. The Aboriginal women were younger and more likely to have advanced spread of disease when diagnosed than non-Aboriginal women. Aboriginal women were less likely than non-Aboriginal women to receive surgical treatment (odds ratio 0.59, 95% confidence interval (CI) 0.42-0.86). The five-year crude breast cancer-specific mortality was 6.1% higher for Aboriginal women (17.7%, 95% CI 12.9-23.2) compared with non-Aboriginal women (11.6%, 95% CI 11.2-12.0). After accounting for differences in age at diagnosis, year of diagnosis, spread of disease and surgical treatment received the risk of death from breast cancer was 39% higher in Aboriginal women (HR 1.39, 95% CI 1.01-1.86). Finally after also accounting for differences in comorbidities, socioeconomic disadvantage and place of residence the hazard ratio was reduced to 1.30 (95% CI 0.94-1.75). CONCLUSION: Preventing comorbidities and increasing rates of surgical treatment may increase breast cancer survival for NSW Aboriginal women.
