This study focused on identifying the factors that help students successfully transition from a remote community to boarding school.

The study used an explanatory sequential mixed methods approach to investigate and analyse the experiences of Aboriginal students at a regional boarding school in the …

The Placenta And Cardiovascular Disease: A Meta-Analysis, Ruben Phillips

Theses: Doctorates and Masters

The uterine environment in which a fetus grows and develops is now recognised as a risk factor for the development of adult diseases such as cardiovascular disease (CVD). A fetus relies on the nutrients and conditions delivered via the placenta, and as such the placenta plays a vital role in the establishment and maintenance of appropriate uterine conditions. Unfavourable uterine conditions such as an inadequate resource flow from the placenta can lead to diminished growth of the fetus and may ultimately result in both short and long-term increases in risk of CVD for the baby. This has been demonstrated in …

Research outputs 2014 to 2021

Introduction: Metformin is the most widely administered anti-diabetic medication among type 2 diabetes mellitus (T2DM) patients. However, metformin induces vitamin B12 malabsorption which may increase the risk of vitamin B12 deficiency among T2DM patients. We determined the prevalence of vitamin B12 deficiency and related risk factors among Ghanaian T2DM patients on metformin therapy. Methods: This cross-sectional study recruited 196 T2DM patients attending the outpatient diabetic clinic at the Effia Nkwanta Regional Hospital, Ghana. Fasting venous blood was collected for biochemical analysis. Vitamin B12 deficiency was defined as serum B12 < 100 pg/ml and methylmalonic acid (MMA) ≥ 0.4µmol/L. Results: The prevalence of vitamin B12 deficiency based on serum vitamin B12, MMA, and the combination of both methods were 32.1%, 14.8%, and 14.3%, respectively. Longer duration of metformin use [5-9 years, aOR= 2.83, 95% CI (1.03-7.81), p=0.045 and ≥ 10 years, aOR= 4.17, 95% CI (1.41-12.33), p=0.010], higher daily dose of metformin [1000-2000 mg/day, aOR= 1.34, 95% CI (0.25-2.74), p=0.038 and > 2000 mg/day, aOR= 1.13, 95% CI (0.39-2.97), p=0.047], and very high …

Being A Bad Vegan, Lelia Green

Research outputs 2014 to 2021

According to The Betoota Advocate (Parker), a CSIRO (Commonwealth Scientific and Industrial Research Organisation) paper has recently established that “it takes roughly seven minutes on average for a vegan to tell you that they’re vegan” (qtd. in Harrington et al. 135). For such a statement to have currency as a joke means that it is grounded in a shared experience of being vegan on the one hand, and of encountering vegans on the other. Why should vegans feel such a need to justify themselves? I recognise the observation as being true of me, and this article is one way to …

Intergenerational Influences Of Hunger And Community Violence On The Aboriginal People Of Western Australia: A Review, Francesca Robertson, David Coall, Dan Mcaullay, Alison Nannup

Research outputs 2014 to 2021

There is a consensus in the literature that hunger and community violence inaugurates adverse health impacts for survivors and for their descendants. The studied cohorts do not include Western Australian Aboriginal people, although many experienced violence and famine conditions as late as the 1970s. This article describes the pathways and intergenerational impacts of studied cohorts and applies these to the contemporary Western Australian context. The authors found that the intergenerational impacts, compounded by linguistic trauma, may be a contributor to current health issues experienced by Aboriginal people, but these are also contributing to the resurgence in population numbers.

Home Childbirth Among Young Mothers Aged 15-24 Years In Nigeria: A National Population-Based Cross-Sectional Study, Emmanuel O. Adewuyi, Vishnu Khanal, Yun Zhao, Lungcit David, Olasunkanmi D. Bamidele, Asa Auta

Research outputs 2014 to 2021

Objective To estimate the prevalence and identify factors associated with home childbirth (delivery) among young mothers aged 15–24 years in Nigeria. Design A secondary analysis of cross-sectional data from the 2013 Nigeria Demographic and Health Survey (NDHS). Setting Nigeria. Participants A total of 7543 young mothers aged 15–24 years. Outcome measure Place of delivery. Results The prevalence of home delivery among young mothers aged 15–24 years was 69.5% (95% CI 67.1% to 71.8%) in Nigeria—78.9% (95%CI 76.3% to 81.2%) in rural and 43.9% (95%CI 38.5% to 49.5%, p < 0.001) in urban Nigeria. Using the Andersen’s behavioural model, increased odds of home delivery were associated with the two environmental factors: rural residence (adjusted OR, AOR: 1.39, 95% CI 1.06 to 1.85) and regions of residence (North-East: AOR: 1.97, 95% CI 1.14 to 3.34; North-West: AOR: 2.94, 95% CI 1.80 to 4.83; and South-South: AOR: 3.81, 95% CI 2.38 to 6.06). Three of the enabling factors (lack of health insurance: AOR: 2.34, 95% CI 1.16 to 4.71; difficulty with distance to healthcare facilities: AOR: 1.48, 95% CI 1.15 to 1.88; and < 4 times antenatal attendance: AOR: 3.80, 95% CI 3.00 to 4.85) similarly increased the odds of home delivery. Lastly, six predisposing factors—lack of maternal and husband’s education, poor wealth index, Islamic religion, high parity and low frequency of listening to radio—were associated with increased odds of home delivery. Conclusions Young mothers aged 15–24 years had a higher prevalence of home delivery than the national average for all women of reproductive age in Nigeria. Priority attention is required for young mothers in poor households, rural areas, North-East, North-West and South-South regions. Faith-based interventions, a youth-oriented antenatal care package, education of girls and access to health insurance coverage are recommended to speed up the reduction of home delivery among young mothers in Nigeria.

The Current State Of Subjective Training Load Monitoring—A Practical Perspective And Call To Action, Joseph O. C. Coyne, G. Gregory Haff, Aaron J Coutts, Robert U. Newton, Sophia Nimphius

Research outputs 2014 to 2021

This commentary delivers a practical perspective on the current state of subjective training load (TL) monitoring, and in particular sessional ratings of perceived exertion, for performance enhancement and injury prevention. Subjective measures may be able to reflect mental fatigue, effort, stress, and motivation. These factors appear to be important moderators of the relationship TL has with performance and injury, and they also seem to differ between open and closed skill sports. As such, mental factors may affect the interaction between TL, performance, and injury in different sports. Further, modeling these interactions may be limited due to the assumption that an …
