There has been considerable debate among cognitive psychologists and epidemiologists regarding which determinants of children’s intelligence are most important. Factors such as children’s diet, maternal stress and social support are important for general health and wellbeing, but have received little research attention in longitudinal studies involving cognitive outcomes. Few studies have examined the determinants of intelligence in children born small-for-gestational age (SGA) at term even though these children may be particularly vulnerable to poorer postnatal environments. The aim of this study was to identify factors associated with cognitive ability in middle childhood in New Zealand (NZ) European children and children born SGA. The present research was conducted as part of the Auckland Birthweight Collaborative (ABC) study. Approximately half of the children in this study were born SGA (birthweight<10th percentile) and half were born appropriate-for-gestational age (AGA=birthweight>10th percentile). Information was collected from mothers and children on pregnancy, obstetric, socio-demographic, postnatal and dietary factors when the children were born (n=871), at one year (n=744), 3.5 years (n=550), and 7 years of age (n=591). Cognitive ability was assessed at 7 years using the Wechsler Intelligence Scale for Children – Third Edition. For the total sample, the analyses utilised weighting to allow for the disproportionate sampling of children born SGA. Results showed that SGA and AGA children did not differ in intelligence at 7 years. Factors associated with intelligence included maternal pregnancy factors (e.g. hypertension), socio-demographic factors (e.g. paternal education), and postnatal factors (e.g. maternal social support). In general, the effects of environmental factors did not differ significantly for SGA children compared with AGA children. A number of dietary factors were also found to be significantly and positively associated with intelligence measures including higher intakes of breads and cereals and weekly fish consumption. In contrast, daily margarine consumption was associated with significantly lower intelligence scores, particularly in SGA children, and this is the first study to report this association. iii Dietary and “environmental” factors were stronger predictors of children’s intelligence in middle childhood than “biological” factors, such as infant’s birthweight. Importantly, most of the factors associated with intelligence that were identified in this study are potentially modifiable. Further research is needed to examine whether these factors continue to be associated with cognitive ability in later childhood.

A Health Promoting School (HPS) approach is now widely accepted internationally, with a focus on children’s health, the school curriculum, and whole school environment. In Thailand, the health and well-being of children is a fundamental value. HPS programmes have been implemented in schools as a strategy to focus on young people’s health. A number of barriers to successful HPS have been identified. While there is international evidence to show the steps and the key factors in creating successful HPS, little is known about successful HPS in the Thai context, in particular, in Northeastern Thailand which has been classified the poorest region. Ethnographic methods were used to examine what understanding of the meaning of HPS is necessary for a successful school, and how all those involved acted from the adoption of the HPS programmes by the local school until it achieved HPS status. A rural school which was successful in a HPS programme was selected, in Mahasarakham province, Northeastern Thailand. The data were obtained through participant observation, ethnographic interviews, and ethnographic records, and data analysis took place simultaneously with data collection. In this study, Lofland’s strategy for the analysis of the structure of human interaction was used. A variety of techniques for improving and documenting the credibility of the study such as prolonged engagement, persistent observation, and triangulation were used. This research revealed that the informants’ views reflected diverse understandings of the meaning of HPS. Those views were based on their experiences of HPS which differed according to the degree of participation, different levels of knowledge about HPS, and in the roles they played in the implementation of HPS in the school. Thai culture and school ethos influenced the success of HPS. Community participation was also crucial in supporting the school’s achievement. Key factors that underpinned success are identified. Implications of the findings for the HPS programme, health professionals, the school and community are discussed.

Children are often referred to as the 'hidden' generation, a powerless group who in infancy and childhood depend on their parents and families/whanau to ensure they receive everything in life required to enable them to grow into healthy young people and adults. Some are more disadvantaged than others due to the socioeconomic circumstances they grow up in. This can have lasting effects on their health in childhood with associated impacts later in life. In New Zealand the populations of children most disadvantaged are those from Maori, Pacific and other low income families/whanau. The disparities that exist between children from these populations and other groups whilst lessening, is still significant. The purpose of this study was to explore with Maori, Pacific and low income parents and caregivers why they choose to 'seek' health services for their children, or not as the case may be. Patterns of use are established early in life therefore it is important to understand children's health care use. The literature suggests that children's access to health care is influenced by predisposing factors such as their socioeconomic status, ethnicity, the availability of services, choice of providers, availability of school–based health services, outreach services, relationships between the community and health service providers and having a regular source of primary health care. A qualitative exploratory design was the methodology chosen for this research. A modified 'community as partner' model (Anderson, 2008) formed the conceptual framework for the research. Sixteen Maori, Pacific and Pakeha parents and caregivers participated in three focus groups to discuss their perceptions of children's access to health care. Thematic analysis was used to identify codes, categories, themes and sub themes from the data. The New Zealand Child Health Strategy (Ministry of Health, 1998) was used as a model to inform the discussion. The main themes were: reality of life, visibility, knowing you, knowing me and kids come first. The findings suggest that relationships with primary health care providers, the cost of health care for children over five years, awareness of services and a need to prioritise children's needs, enable or prevent children's access to health care. Decisions made regarding further service provision for children will be enhanced by health providers and practitioners having a clearer understanding of the enablers and barriers to access and the factors that influence parental choice of services.

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.

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.
