    Nursing care for people living with diabetes and associated conditions in Fiji : an iTaukei community context : a thesis presented in fulfilment of the requirements for the degree of Doctor of Philosophy, Massey University, Palmerston North, New Zealand
    (Massey University, 2021) Ravono, Akisi Nailaba
    This research examined the experiences of iTaukei (indigenous people of Fiji) patients and nurses in the context of the diabetes epidemic in Fiji. Vanua theory, which has some influence on iTaukei health beliefs and practices through its physical, social and cultural elements informed the design and conduct of the research. Despite the voluminous global literature on diabetes and non-communicable diseases (NCD), there was little written about the topic for Fiji and the Pacific. Fiji was among the first few countries to adopt public health initiatives that were developed to curb the incidence of NCD. However, such initiatives have faced a perpetual challenge in terms of implementation, monitoring and evaluation. The research used the Fijian Vanua Research Framework and veitalanoa, a data collection method, to gather information from twelve patients and eleven nurses from four medical areas in Fiji. The veitalanoa groups were complemented by four veitalanoa individual sessions and field observations. Findings revealed that patients struggled to cope with diabetes and associated complications while nurses were challenged to deliver best practice in inadequate nursing practice environments. Specifically, patients had difficulties both living with diabetes and accessing planned care and were culturally unlikely to question or challenge medical decisions, simply expecting safe and trustful care. Nurses were not able to nurse in the way they know is needed; they provided rudimentary and sometimes inappropriate care, and experienced extreme frustration while attempting to provide holistic care in a highly medicalised model of care. The nurses were aware of vanua etiquette and their connections with iTaukei patients, however, they could not apply such protocol. Despite study findings revealing significant challenges for patients and nurses, the participants suggested a way forward for the improvement of nursing care and primary health care in Fiji. Such changes may represent considerable challenge to the accepted hierarchies of power and decision making and will need to be strongly supported by a focus on patient centered care.

    The South Pacific Islands Resist Diabetes With Intense Training (SPIRIT) Study : impact of progressive resistance training and aerobic training on glycaemic control in Māori and Pacific Islands people with type 2 diabetes and grade III obesity : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Exercise and Sport Science, Institute of Food, Nutrition, and Human Health, College of Sciences, Massey University at Wellington, New Zealand
    (Massey University, 2010) Sukala, William Reed
    The purpose of the South Pacific Islands Resist diabetes with Intense Training (SPIRIT) study was to evaluate and compare the effectiveness of two conventional training modalities for improving glycosylated haemoglobin (HbA1c) and related physiological and psychological outcomes in Polynesian adults diagnosed with type 2 diabetes and visceral obesity. Twenty-six adults of self-identified Māori or Pacific Islands descent (20 women, 6 men; 47 ± 8 years; 116.3 ± 27.5 kg; waist circumference 124.0 ± 17.8 cm) were randomised to progressive resistance training (PRT) or aerobic training (AER), 3x/week, for 16 weeks. Nine subjects per exercise group (n = 18) completed the study and were included in per protocol analyses. Within-group ANOVAs revealed that HbA1c remained elevated in PRT and AER after 16 weeks of training (10.7 ± 2.1 to 10.6 ± 2.4%, P > 0.05; 8.9 ± 1.9 to 8.8 ± 2.1%, P > 0.05, respectively). AER resulted in significant reductions in systolic (P = 0.006) and diastolic blood pressure (P = 0.02), an increase in skeletal muscle GLUT4 (P = 0.02), capillary density (P = 0.05), and power output (watts) (P < 0.001), while PRT resulted in a significant increase in upper (P = 0.001) and lower body strength (P < 0.001) and a reduction in hip circumference (P = 0.05). Eight (5 AER, 3 PRT) of 18 subjects completed ≥ 75% of available training sessions. Post-hoc analysis on these eight patients revealed a significant reduction in waist circumference (P < 0.001). Despite low attendance, many SF-36 QOL domains scores and the Physical Component Summary scores significantly improved in both groups (P ≤ 0.002). The findings of this doctoral research project suggest that improvement of metabolic outcomes may be delayed or overwhelmed by a combination of low attendance and class III morbid obesity (BMI ≥ 40 kg/m2). The improvements observed in QOL and muscle outcomes suggest that psychological and myocellular changes may precede changes in systemic metabolic outcomes. Additional research is required to investigate these hypotheses and overcome barriers to exercise adoption in Māori and Pacific Islands people with morbid obesity and type 2 diabetes.
