A Pilot Evaluation of Wellfed, a Community-Based Adult Education Intervention
The pilot study shows the effectiveness of the WELLfed programme for improving food knowledge and skills, reducing food insecurity, and improving health outcomes. Further research with a larger sample size is required to confirm these pilot results
More players can reach national and international levels”
Relative age effects (RAEs) are common across many youth sports that use age group structures to band athletes. This creates a significant overrepresentation of those who are born near the start of the selection cut-off date across talent pathways compared to those born towards the end. In an attempt to identify, select, and develop the most talented squash players based upon their long-term potential, England Squash designed and implemented the …
Consequences of barriers to primary health care for children in Aotearoa New Zealand
Inequities in the provision of accessible primary health care contribute to poor health outcomes and health inequity. This study evaluated inequities in the prevalence and consequences of barriers that children face in seeing a general practitioner (GP) in Aotearoa New Zealand. We analysed data on 5,947 children from the Growing Up in New Zealand longitudinal study cohort on barriers to seeing a GP in the previous year, reported by mothers when t…
The enrolment gap
Enrolments remain below full population coverage and inequities exist between socio-demographic and geographic groups. Potential reasons explaining these trends include methodological limitations as well as real issues in accessing services. We recommend (a) work towards minimising data issues in relation to this indicator to improve its accuracy and value in signalling trends in access to PHC services, and (b) investigating the reasons for the p…
Equity in access to zero-fees and low-cost Primary Health Care in Aotearoa New Zealand
"Birthday-Banding" as a Strategy to Moderate the Relative Age Effect
The relative age effect (RAE) is almost pervasive throughout youth sports, whereby relatively older athletes are consistently overrepresented compared to their relatively younger peers. Although researchers regularly cite the need for sports programs to incorporate strategies to moderate the RAE, organizational structures often continue to adopt a one-dimensional (bi)annual-age group approach. In an effort to combat this issue, England Squash imp…
Ethnic differences in risk factors for obesity in New Zealand infants
BACKGROUND: In New Zealand, the burden of childhood obesity is greatest in Māori and Pacific children. METHODS: In 687 infants from an internet-based birth cohort in New Zealand, we investigated ethnic differences in early life risk factors for later obesity, the degree to which these were explained by sociodemographic factors, and the extent to which ethnic differences in weight at age 3 months were explained by measured risk factors. RESULTS: T…

Investigating reasons for ethnic inequalities in breast cancer survival in New Zealand
Ethnic disparities in breast cancer survival in New Zealand can be attributed to deprivation and differential access to health care rather than differences in breast cancer subtypes
P2-92 Hormone markers and asthma in young adulthood
Introduction Prevalence of asthma is higher in boys during childhood but in women in adulthood. Recent studies point to the role of hormones in explaining these gender-age differences but often single markers of hormone levels have been assessed. The aim of this study is to investigate the association of history of asthma in young adulthood with different hormone markers during adolescence. Methods Historical cohort of students (11 274 men and 35…
P1-278 Associations between socioeconomic position and asthma- findings from a historical cohort
Introduction The association between asthma and socioeconomic position (SEP) is not well understood. This study aims to assess the variation in asthma across SEP in a historical cohort before the rise in asthma prevalence. Methods Students participating in a health survey at Glasgow University from 1948 to 1968 (11 274 men; 3502 women) completed a medical history of bronchitis, asthma, hay fever, eczema/urticaria, and reported early life SEP. A s…
Characteristics of ovarian cancer in women residing in Aotearoa, New Zealand
BACKGROUND: Few studies have compared ovarian cancer rates between different ethnic groups in the same country. The aim of this study was to describe ethnic patterns in the incidence and mortality of ovarian cancer in New Zealand, and to investigate ethnic and socioeconomic differences in the grade and stage of ovarian cancer. METHODS: Data on all women registered with ovarian cancer on the New Zealand Cancer Registry (1993-2004) were analysed. P…

Effects of self-reported racial discrimination and deprivation on Māori health and inequalities in New Zealand
Childhood socioeconomic circumstances predict specific causes of death in adulthood
2] A new analysis of the Kuopio study using historical records of childhood socioeconomic circumstances finds higher mortality risk among those who experienced worse circumstances in childhood 4 that was not found when only recalled childhood socioeconomic position (SEP) was available. 5 Thus, using contemporaneously collected measures of childhood SEP seems to provide better estimates of the true association with later disease. Furthermore, the …

Ethnic differences in cause specific mortality among hospitalised patients with diabetes
Study objective: To describe patterns of excess mortality among patients with diabetes in three ethnic groups. Design: A linkage study of national hospital discharge records to death records. Setting: New Zealand. Participants: The study included 74 847 patients (11 268 Māori, 5730 Pacific, and 57 849 non-Māori/non-Pacific) aged over 25 years with a hospital discharge diagnosis of diabetes between 1988 and 2001. By the end of 2001, 29 295 (39%) o…
Ethnic Inequalities in Cancer Survival in New Zealand
We explored the contribution of stage at diagnosis to ethnic disparities in cancer survival in New Zealand. We linked 115811 adult patients with invasive cancer registered on the cancer registry (1994 to 2002) to mortality data. Age-standardized, 5-year relative survival rates were lowest for Maori, intermediate for Pacific people (otherwise known as Pacific Islanders), and highest for non-Maori/non-Pacific people for many cancers. Stage at diagn…
