Immersed in a context of constrained health resources, nurse managers are at great risk of the experience and negative consequences of values clashes and ethical conflict, such as burnout and attrition. Replicating a qualitative descriptive study previously conducted in Canada (Gaudine & Beaton, 2002) this research is aimed at increasing knowledge of the experience of nurse managers’ ethical conflict with their health care organizations in New Zealand. Semi-structured interviews were used to gather data from eight nurse managers in New Zealand, which was analyzed using a general inductive approach to qualitative research. The experience of advocating for values that may be shared by both nursing and the health care organization, such as safety, teamwork and quality patient care, were revealed in the conceptual category of Nursing Management Advocacy. As with their Canadian study counterparts, Isolation was revealed as a key factor that made the experience of ethical conflict worse and involves the social experiences of silencing, employment barriers and invisibility. Support describes the factors that mitigated the experience of ethical conflict and involves personal, professional and organizational support, and are likewise similar to the experiences of Canadian nurse managers. The Bottom Line describes a focal point of the experience of ethical conflict where the health care organizations predominantly fiscal bottom line was confronted and challenged by nurse managers, and where the nurse manager might reach their own bottom line and choose to leave the organization. Being and Becoming Nursing Leaders describes the outcomes of ethical conflict for nurse managers who were not only transformed into nursing leaders, through learning, reflection, and growth but also counted the costs of nursing leadership. This study concludes that supportive colleagues, organizational structures and culture are essential to mitigating the experience of ethical conflict and isolation which nurse managers encounter. The study also concludes that reducing isolation and supporting nurse managers will ensure that nursing values are appropriately represented and articulated in the health care organization’s decision making systems and processes.

High levels of diet related chronic disease in New Zealand has lead to the development of health promotion programmes. The work place is an important venue to implement health promotion programmes to encourage staff to make healthy lifestyle choices. The aim of this research is to examine if a physical activity programme may be a ‘gateway’ to other positive behavioral changes such as healthy eating and/or cutting down smoking. This research introduces a health promotion programme to employees at a call centre. The intervention involved 3 groups: the health promotion group (HPG), which received both the physical activity programme (10,000 steps @ work ‘lite’ programme) plus nutritional information; the nutritional group (NG), which received only the nutritional information and the control group (CG), which did not take part in the intervention. The impact of the nutritional seminars with or without the exercise programme was measured by the participants’ reported fruit, vegetable, snack consumption and transtheoretical stages of change for exercise, fruit and vegetable intake, healthy snacking and smoking. A questionnaire was used to collect data retrospectively. The health promotion group (HPG) made positive changes in all behaviours unlike the nutritional group (NG) and the control group (CG). This provides some support for the hypothesis that physical exercise may act as a ‘gateway’ to other positive behavioural changes.

Citizenship, as effective social, cultural and economic participation for refugee groups, depends on appropriate institutional structures and processes in resettlement societies. This thesis using critical social theoretical perspectives addresses the paradox of being legally a citizen, but substantively excluded from the very rights that constitute such citizenship. The thesis draws on theoretical models of newcomer integration in order to promote the development of a more inclusive society for refugees in New Zealand. The issues to be considered include responses from central government and from public institutions—particularly health, education, employment and welfare—in addressing social exclusion and promoting integration. The questions of refugee integration to be addressed conceptually must take into consideration cultural and religious diversity, on the one hand, and socio-economic inequality on the other. In New Zealand, the 1987 review of refugee resettlement policy, which established an annual quota of 750 places, has given priority to those with the highest health and social needs and removed preferences for specific national, ethnic and religious groups. Significantly, in the 1990s radical neo-liberal economic reforms were introduced and publicly provided health, education and welfare systems were restructured. This posed serious challenges to the core idea of social citizenship in general in New Zealand society. Noticeable ethnic diversification has been just one element of the resettlement policy changes; the other has been long-term social and economic exclusion in the refugee groups settled since this time. This study indicates that New Zealand’s notably humanitarian refugee resettlement policy is not matched by adequate central government and public institutional responses and resources with which to integrate refugee groups. This qualitative study examines the role of one institution in particular, health care. The study takes a multi-method approach, using historical and social policy analysis to set the structural context for the interpretation of data from participant interviews. During fieldwork, twenty-eight semi-structured interviews were conducted with health care providers in community, primary and secondary care sectors in the Auckland region, in both governmental and non-governmental agencies. This research demonstrates at a service level, the consequences of overlooking refugee peoples in New Zealand social policy, data collection systems, research and health strategies. Importantly though, the research discovers a number of ‘activation points’—or approaches that have been developed by health care practitioners—that highlight future opportunities for the inclusion of refugee groups. One finding is that the New Zealand health system must address the question of how to effect a shift from universalist conceptions of generalised eligibility for health services to targeted interventions for refugees. The conclusions drawn from the study are: firstly, that an overarching integration policy for refugees, led by central government, is required. Secondly, institutional responses that accommodate the special psychosocial, socio-economic and cultural/religious requirements of refugee groups are needed. This would include the development of a locally relevant multiculturalism to guide social policy in New Zealand. In the long-term, for peoples from refugee backgrounds to become full political, social, economic and cultural members of New Zealand society, there needs to be a rethinking of the contemporary models of citizenship offered.

Recent Māori, sexual, and primary health developments have been influenced by the principle of participation. For example, the use of a whānau-centred approach, of community development, and of Primary Health Organisations allows participation in decision-making. However, none of the abovenamed strategies adequately explain how young Māori women can participate in decision-making in one common area: Māori, sexual, primary health policy. This thesis explores how Primary Health Organisations can work with young Māori women to promote sexual health to whānau by focusing on policymaking processes and effective participation mechanisms. Māori health development from colonial Contact to 2005 is reviewed before the broad health framework (the New Zealand Health Strategy and the New Zealand Public Health and Disability Act 2000) is defined. A critique of relevant policy, in particular He Korowai Oranga (2002), the Sexual and Reproductive Health Strategy (2001), and The Primary Health Care Strategy (2001), reveals scope for participation and whānau-centredness. Primary Health Organisations pose challenges to whānau sexual health promotion. However, with public participation from young Māori women, like the thesis participants, new opportunities can be realised. The research was conducted in accordance with a Mana Wāhine-based methodology called Tāniko The four parts (Mana Wāhine, Te Ao Tawhito, Te Ao Hou, and Te Ao Mārama) defined the research aim and objectives. A qualitative strategy employing semi-structured interviews with three young Māori women was followed by a confirmatory stage of content analysis utilising a deductive public participation evaluation tool: the Tāniko instrument. The instrument analysed four policymaking decisions and two mechanisms: organised peer groups and the wāhine-centred approach. The research concluded that when defining how, by whom, and to whom information is presented, organised peer groups can be utilised at the coordination and evaluation policymaking stages. The wāhine-centred approach can share or manage participation through problem definition, consultation, decision, and implementation.

Previously published New Zealand literature suggested that Māori and Pacific children were less likely than NZ European children to receive asthma medications and elements of asthma education, had poorer knowledge of asthma, and experienced greater morbidity and hospitalisations. However, none of the previous literature had been specifically designed to assess the nature of asthma care in the community, or to specifically answer whether there were ethnic disparities in care. A systematic review of studies published in the international literature that compared asthma management among different ethnic groups drawn from community-based samples was undertaken. The results of this review suggested that minority ethnic group children were less likely to receive elements of asthma medication use, asthma education and self-management (action) plans. Objectives The primary objectives of the study were to: • describe the use of medications, medication delivery systems, asthma education, and self-management plans in primary care for Māori, Pacific, and Other ethnic group children • ascertain whether there were any ethnic disparities in the use of medications, medication delivery systems, asthma education, and self-management plans in primary care after controlling for differences in socio-economic position and other potential confounders. Secondary objectives were to: • describe the asthma-related utilisation of GP, after hours medical care, emergency departments, and hospital admissions among Māori, Pacific, and Other ethnic group children with asthma • ascertain whether differences in medication use, the provision of asthma education, and the provision of self-management plans explained ethnic differences in health service utilisation. Methods A cross-sectional survey was conducted in Auckland, New Zealand. The caregivers of 647 children who were aged 2–14 years, had a diagnosis of asthma or experienced ‘wheeze or whistling in the chest’, and had experienced symptoms in the previous 12 months were identified using random residential address start points and door knocking. Ethnically stratified sampling ratios were used to ensure that approximately equal numbers of children of Māori, Pacific and Other ethnicity were enrolled into the study. A face-to-face interview was conducted with the caregivers of these children. Data was collected about: socio-demographic factors; asthma morbidity; asthma medications and delivery devices; exposure to, and experiences of, asthma education and asthma action plans; and asthma-related health services utilisation. Results In this study, the caregivers of 647 eligible children were invited to participate and 583 completed the interview, giving an overall completion rate of 90.1%. There were no ethnic differences in completion rates. The overall use of inhaled corticosteroid medications had increased since previous New Zealand research was published. Multivariable modelling that adjusted for potential confounders did not identify ethnic differences in the use of inhaled corticosteroids or oral steroids. Some findings about medication delivery mechanisms indicated that care was not consistent with guidelines. About 15% of participants reported they had not received asthma education from a primary care health professional. After adjusting for potential confounders there were no ethnic differences in the likelihood of having received asthma education from a health professional. Among those participants who had received education from a primary care health professional, significantly fewer Māori and Pacific caregivers reported receiving education about asthma triggers, pathophysiology and action plans. Lower proportions of Pacific (77.7%; 95% confidence interval (95%CI) 70.3, 85.1) and Māori (79.8%; 95% CI 73.6, 85.9) caregivers were given information about asthma triggers compared to Other caregivers (89.2%; 95% CI 84.9, 93.6; p=0.01). Fewer Māori (63.6%; 95% CI 55.7, 71.4) and Pacific (68.1%; 95% CI 60.1, 76.1) caregivers reported receiving information about pathophysiology (Other 75.9%; 95% CI 69.5, 82.3; p=0.05). Information about asthma action plans had been given to 22.7% (95% CI 15.5, 29.9) of Pacific and 32.9% (95% CI 25.3, 40.6) of Māori compared to Other participants (36.5%; 95% CI 28.6, 44.3; p=0.04). In addition, fewer Māori (64.2%; 95% CI 56.1, 72.3) and Pacific (68.5%; 95% CI 60.1, 77.0) reported that the information they received was clear and easy to understand (Other 77.9%; 95% CI 71.8, 84.1; p=0.03). About half of those who had received education from a health professional reported receiving further education and, after adjustment for potential confounders, Pacific caregivers were less likely to have been given further education (odds ratio 0.57; 95% confidence interval 0.33, 0.96). A minority of participants (35.3%) had heard about action plans and, after adjustment for potential confounders, Pacific caregivers were less likely to have heard about these plans (odds ratio 0.54; 95% confidence interval 0.33, 0.96). About 10% of the sample was considered to have a current action plan. The mean number of visits to a GP for acute and routine asthma care (excluding after-hours doctors and medical services) in the previous twelve months were significantly higher for Pacific (3.89; CI 3.28, 4.60) and Māori (3.56; CI 3.03, 4.16) children than Other ethnic group children (2.47; CI 2.11, 2.85; p<0.0001). Multivariable modelling of health service utilization outcomes (‘number of GP visits for acute and routine asthma care in the previous twelve months’, ‘high use of hospital emergency departments’, and ‘hospital admissions’) showed that adjustment for potential confounding and asthma management variables reduced, but did not fully explain, ethnic differences in these outcomes. Māori children experienced 22% more GP visits and Pacific children 28% more visits than Other children (p=0.05). Other variables that were significantly associated with a higher number of GP visits were: regular source of care they always used (regression coefficient (RC) 0.24; p<0.01); lower household income (RC 0.31; p=0.004) and having a current action plan (RC 0.38; p=0.006). Increasing age (RC -0.04; p=0.003), a lay source of asthma education (RC -0.41; p=0.001), and higher scores on asthma management scenario (RC -0.03; p=0.05) were all associated with a lower number of GP visits. Pacific (odds ratio (OR) 6.93; 95% CI 2.40, 19.98) and Māori (OR 2.60; 95% CI 0.87, 8.32) children were more likely to have used an emergency department for asthma care in the previous twelve months (p=0.0007). Other variables that had a significant effect on the use of EDs in the multivariable model were: not speaking English in the home (OR 3.72; 95% CI 1.52, 9.09; p=0.004), male sex (OR 2.43; 95% CI 1.15, 5.15; p=0.02), and having a current action plan (OR 7.85; 95% CI 3.49, 17.66; p<0.0001). Increasing age was associated with a reduced likelihood of using EDs (OR 0.90; 95% CI 0.81, 1.00; p=0.05). Hospitalisations were more likely in the Pacific (OR 8.94; 95% CI 2.25, 35.62) and Māori (OR 5.40; 95% CI 1.28, 23.06) ethnic groups (p=0.007). Four other variables had a significant effect on hospital admissions in the multivariable model. Participants who had a low income (OR 3.70; 95% CI 1.49, 9.18; p=0.005), and those who had a current action plan (OR 8.39; 95% CI 3.85, 18.30; p<0.0001) were more likely to have been admitted to hospital in the previous 12 months. Increasing age (OR 0.88; 95% CI 0.80, 0.98; p=0.02) and parental history of asthma (OR 0.39; 95% CI 0.18, 0.85; p=0.02) were associated with reduced likelihood of admission. Conclusions The study is a robust example of cross-sectional design and has high internal validity. The study population is representative of the population of children with asthma in the community. The three ethnic groups are also considered to be representative of those ethnic groups in the community. The study, therefore, has good representativeness and the findings of the study can be generalised to the wider population of children with asthma in the Auckland region. The results suggested that some aspects of pharmacological management were more consistent with guideline recommendations than in the past. However, given the higher burden of disease experienced by Māori and Pacific children, the lack of observed ethnic differences in the use of preventative medications may reflect under treatment relative to need. There are important ethnic differences in the provision of asthma education and action plans. Future approaches to improving care should focus on interventions to assist health professionals to implement guideline recommendations and to monitor ethnic disparities in their practice. Asthma education that is comprehensive, structured and delivered in ways that are effective for the people concerned is needed.

Although the effects of noise on children’s learning in school classrooms is well documented, there is very little on the effects of noise on preschool children. There are strict legal requirements for the daily noise exposure an adult worker can received in the workplace but nothing to control the noise children can receive in school and early education. There is also little or no data on how sound affects a child, compared to an adult. The early years of life are critical for the development of speech, hearing and auditory processes, as well as being the most vulnerable time for middle ear infections. This work sets out to determine the typical noise levels in early childhood centres and the effects on a range of children and their teachers. Reverberation times in most centres were found to well exceed the 0.6 seconds prescribed by the Australasian standard for schools and learning spaces. Very high levels of noise were recorded in a number of centres with a significant number of children and staff members, exceeding the maximum daily sound exposure of 100% permitted for workers in industry. A range of special needs children were identified as being particularly at-risk to noise, with the most adverse outcomes reported for those experiencing sensory integration disorder. Yet, even though high levels of noise were recorded, the majority of respondents in a survey of teachers rated the lack of sufficient space for the number of children present as the main issue, and inclement weather as the greatest environmental condition contributing to noise (by confining children indoors, especially over long periods of time). Hearing tests on the children were not permitted under the strict human ethics criteria to which this study had to conform, but simple hearing tests on a small group of teachers, revealed that hearing loss could be a serious occupational health issue. The legal issues of noise control and management in early childhood education have been addressed in this thesis, current legal frameworks reviewed, and recommendations presented for future consideration.

In New Zealand Māori are under-represented in the workforce across multiple sectors. This thesis explores this incongruity with regard to Māori health. A Māori perspective and philosophical foundation formed the basis of the methodological approach, utilising a case study research design to inform the study. This provided the opportunity to explore Māori health workforce development initiatives and their potential to contribute to improvements and gains in Māori health. It was important that this work take into account social and economic factors and their impact on health, as well as the varying political climates of market oriented reform and a fiscal policy focus, because it has not only challenged Māori health development but also provided opportunities for increased Māori involvement and participation in health and New Zealand society. Therefore the thesis, while focused on health takes cognisance of and, coincides with the capacity and capability building efforts that have been a feature of overall Māori development, progress and advancement. In the context of this thesis Māori health workers are seen as leaders within their whānau, hapū, iwi, and Māori communities. Consequently a potential workforce that is strong and powerful can lead to anticipated gains in Māori health alongside other Māori movements for advancement. The potential cannot be under-estimated. This thesis argues that there are critical success factors, specific determinants, influencing Māori health workforce potential, and that these success factors have wider application. Therefore, as this thesis suggests Māori workforce development, especially in relationship to the health workforce, is dependent on effective Māori leadership, the application of Māori values to workplace practices, levels of resourcing that are compatible with training and development, critical mass, and targeted policies and programmes.

Background Hypovitaminosis D is becoming recognised as an emerging threat to health, even in countries like New Zealand which enjoy plentiful sunshine. The evidence for a role for vitamin D deficiency in the aetiology of a plethora of diseases continues to accumulate, including type 2 diabetes, and the preceding insulin resistance. Objectives The primary objective of the Surya Study was to investigate the effect of improved vitamin D status (through supplementation) on insulin resistance. The secondary objectives were to investigate the vitamin D status and bone mineral density of South Asian women living in New Zealand, and to investigate the effect of vitamin D supplementation on bone turnover as measured by biochemical markers of bone resorption and formation. Method Women of South Asian origin, ≥20 years old, living in Auckland (n = 235) were recruited for the study. All were asked to complete a 4-day food diary, invited to have a bone scan, and were screened for entry into the intervention phase which required insulin resistance (HOMA-IR >1.93) and serum 25(OH)D < 50 nmol/L. Eighty-one completed a 6-month randomised controlled trial with 4000 IU vitamin D3 (n = 42) or placebo (n = 39). Primary endpoint measures included insulin resistance, insulin sensitivity (HOMA2%S), fasting C-peptide and markers of bone turnover, osteocalcin (OC) and collagen C-telopeptide (CTX). Ninety-one of the 239 had a bone scan and bone mineral density (BMD) was measured in the proximal femur and lumbar spine. Results Adequate serum 25(OH)D concentrations (>50 nmol/L) were observed in only 16% of subjects screened. Median (25th, 75th percentile) serum 25(OH)D increased significantly from 21 (11,40) to 75 (55,84) nmol/L with supplementation. Significant improvements were seen in insulin sensitivity and insulin resistance (P = 0·003, P = 0·02 respectively), and circulating serum insulin decreased (P = 0·02) with supplementation compared to placebo. There was no change in C-peptide with supplementation. Insulin resistance was most improved when endpoint serum 25(OH)D =80 nmol/L. In post-menopausal women OC and CTX levels increased in the placebo arm but CTX decreased from 0.39±0.15 to 0.36±0.17 (P = 0.012) with supplementation. Osteoporosis (T score <-2.5) was present in 32% of postmenopausal, and 3% of premenopausal women. Women 20 – 29 years (n=10) had very low BMD, calcium intake and serum 25(OH)D Conclusions Improving vitamin D status in insulin resistant women resulted in improved insulin resistance and sensitivity but no change in insulin secretion. Optimal 25(OH)D concentrations for reducing insulin resistance were shown to be ≥80 nmol/L. The prevalence of low 25(OH)D concentrations in this population was alarmingly high, especially in younger women. In post-menopausal women, vitamin D supplementation appeared to ameliorate increased bone turnover attributed to oestrogen deficiency.

This study aimed to understand how Maori women negotiate decisions about alcohol and pregnancy. It was based in the recognition that Maori women?s decisions about drinking alcohol when pregnant are shaped by social and cultural expectations about gender roles, as well as their knowledge about alcohol and pregnancy. Maori attitudes to alcohol have also been influenced by colonisation and Maori responses to it. Alcohol use in pregnancy also exists in the context of potential impacts, including fetal alcohol spectrum disorder. There is little knowledge about how and why women may or may not drink during pregnancy. The research used grounded theory methods. Information was gathered through in-depth interviews with ten Maori women. The information they provided was analysed using constant comparative analysis, and a series of categories was generated. The grounded theory proposes that Maori women manage decisions about drinking alcohol when pregnant using a process of Trading off. Trading off is supported by three key processes: drawing on resources, rationalising, and taking control of the role. Maori women start by learning the rules about alcohol, get messages about alcohol and pregnancy, change their alcohol use while making role transitions, and use alcohol in the processes of fitting in where you are, releasing the pressure, and carrying on as normal. Trading off is an individual process, but exists in a complex social context. The process is fluid, conditional, and continues throughout pregnancy. The theory must be recognised as my interpretation, although I believe it is grounded in the data, accounts for the data, and offers a new, modifiable and potentially useful interpretation. While the body of theory that can be compared to the theory of Trading off is limited, the interpretation is consistent with several models of health behaviour, including Maori health models. This research has implications for future research, and for the development of programmes to support Maori women.
