RESUMEN
BACKGROUND: Longitudinal studies can generate valuable scientific knowledge, but can be compromised by systematic attrition. Previous research shows that sociodemographic characteristics (eg, ethnicity, age, educational level, socioeconomic circumstances) are associated with attrition rates. However, little is known about whether these characteristics differ by ethnicity, and how this impacts cohort retention strategies. METHODS: Using antenatal to 12-year data from the Growing Up in New Zealand birth cohort study (N=6743), we examined transversal response rates by ethnicity (Maori, Pacific, Asian, European), used sequence analysis and cluster analysis to identify unique longitudinal response patterns, and binary logistic regression to examine ethnic-specific sociodemographic characteristics associated with these response patterns. RESULTS: The overall response rate at 12 years was 71.0%, with ethnic differences in response rates widening over the six data collection waves. Three longitudinal response patterns were identified: frequent responders (65.2%), intermittent non-responders (29.6%) and frequent non-responders (5.2%). Sociodemographic characteristics such as younger maternal age and lower maternal education were associated with a higher likelihood of membership in the non-response clusters across all ethnic groups. However, there were also important nuances by ethnicity. Individual level factors (eg, household material deprivation and maternal general health) tended to be associated with non-response for Europeans, whereas structural level factors (eg, area-level deprivation and racial discrimination) tended to be associated with non-response for Maori, Pacific and Asian peoples. CONCLUSION: Ethnic differences in longitudinal response patterns are due to multiple factors of disadvantage, and therefore require targeted retention strategies. Stratifying analyses by ethnicity is important for revealing nuanced insights.
RESUMEN
This article explores the processes involved in developing international, cross-cultural research teams. Scholarship on Indigenous and Pacific Methodologies demonstrate the importance of employing methodologies that center Indigenous approaches to research and relationships. This article explores using these methodologies within research teams as a preliminary step in developing sustainable and impactful international, cross-cultural research teams. Although this is not a formal study, the article reports that the importance of building trust within research teams as an essential step in addition to building trust with communities.

INTRODUCTION: Recent estimations have projected a threefold increase in dementia prevalence in Aotearoa New Zealand (NZ) by 2050, particularly in Maori and Pacific peoples. However, to date, there are no national data on dementia prevalence, and overseas data are used to estimate the NZ dementia statistics. The aim of this feasibility study was to prepare the groundwork for the first full-scale NZ dementia prevalence study that is representative of Maori, European, Pacific and Asian peoples living in NZ. METHODS: The main feasibility issues were: (i) Sampling to ensure adequate community representation from the included ethnic groups, (ii) Preparing a workforce to conduct the fieldwork and developing quality control, (iii) Raising awareness of the study in the communities (iv) Maximizing recruitment by door-knocking, (v) Retaining those we have recruited to the study and (vi) Acceptability of study recruitment and assessment using adapted versions of the 10/66 dementia protocol in different ethnic groups living in South Auckland. RESULTS: We found that a probability sampling strategy using NZ Census data was reasonably accurate and all ethnic groups were sampled effectively. We demonstrated that we were able to train up a multi-ethnic workforce consisting of lay interviewers who were able to administer the 10/66 dementia protocol in community settings. The response rate (224/297, 75.5%) at the door-knocking stage was good but attrition at subsequent stages was high and only 75/297 (25.2%) received the full interview. CONCLUSIONS: Our study showed that it would be feasible to conduct a population-based dementia prevalence study using the 10/66 dementia protocol in Maori, European and Asian communities living in NZ, utilizing a qualified, skilled research team representative of the families participating in the study. The study has demonstrated that for recruitment and interviewing in Pacific communities a different but culturally appropriate approach is required.
RESUMEN
Technology and digital platforms have become essential for people and communities to interact because of COVID-19. Despite its benefits, digital exclusion disproportionately affects Pacific communities living in New Zealand. This article provides insights into how Niue mamatua (older adults) used their gifted mobile phones and mobile data as part of a COVID-19 digital inclusion initiative. It begins with an overview of the digital inclusion needs of older adults, followed by a description of the digital va (relational space) and negotiating a new way of maintaining connection in an online world. The tutala (a Niue method of conversation anchored on respect) with 12 mamatua highlighted the benefits, support factors, and challenges of how they were able to use their mobile phone. Importantly, mobile phones provided the necessary access and connectivity to interact in a digitally connected world, namely the digital va, when in-person connections were disrupted because of COVID-19.
RESUMEN
INTRODUCTION: Aotearoa/New Zealand (NZ) is officially recognised as a bicultural country composed of Maori and non-Maori. Recent estimations have projected a threefold increase in dementia prevalence in NZ by 2050, with the greatest increase in non-NZ-Europeans. The NZ government will need to develop policies and plan services to meet the demands of the rapid rise in dementia cases. However, to date, there are no national data on dementia prevalence and overseas data are used to estimate the NZ dementia statistics. The overall aim of the Living with Dementia in Aotearoa study was to prepare the groundwork for a large full-scale NZ dementia prevalence study. METHODS AND ANALYSIS: The study has two phases. In phase I, we will adapt and translate the 10/66 dementia assessment protocol to be administered in Maori, Samoan, Tongan and Fijian-Indian elders. The diagnostic accuracy of the adapted 10/66 protocol will be tested in older people from these ethnic backgrounds who were assessed for dementia at a local memory service. In phase II, we will address the feasibility issues of conducting a population-based prevalence study by applying the adapted 10/66 protocol in South Auckland and will include NZ-European, Maori, Samoan, Tongan, Chinese and Fijian-Indian participants. The feasibility issues to be explored are as follows: (1) how do we sample to ensure we get accurate community representation? (2) how do we prepare a workforce to conduct the fieldwork and develop quality control? (3) how do we raise awareness of the study in the community to maximise recruitment? (4) how do we conduct door knocking to maximise recruitment? (5) how do we retain those we have recruited to remain in the study? (6) what is the acceptability of study recruitment and the 10/66 assessment process in different ethnic groups? ETHICS AND DISSEMINATION: The validity and feasibility studies were approved by the New Zealand Northern A Health and Disability Ethics Committee (numbers 17NTA234 and 18NTA176, respectively). The findings will be disseminated through peer-reviewed academic journals, national and international conferences, and public events. Data will be available on reasonable request from the corresponding author.

OBJECTIVE: To explore factors influencing participation and attrition in a family-led weight-management programme for obese Pacific children. DESIGN: Qualitative study used bilingual in-depth interviews at exit and end of an 8-week weight-management programme. SETTING: New Zealand. SUBJECTS: Forty-two parents/primary caregivers of obese children who were randomised in the intervention weight-management programme. RESULTS: Programmatic factors that enhanced retention included: simultaneous delivery to both children and parents as participants; delivery of the programme in small group settings at local community venues; enabling trustworthy and accountable relationships; providing resources for travel to venues and regular telephone/text messaging follow-up calls reinforcing programme goals; and day and time scheduling. Suggested programme improvements included having ethnic-specific Island-language delivery and practical sessions like cooking classes and shopping expeditions at local food stores. The research found that unpredictable external life crises like extended family deaths, a change in job shift, family illnesses (both acute and those requiring chronic management) and long-term family visitations affected participation and momentum. A loss of momentum through managing life crises was often difficult to overcome for participants, leading them to drop out of the weight-management programme. Most drop-out participants preferred to defer their programme participation with hopes of re-committing to future programmes at another time. CONCLUSIONS: In order for weight-management programmes to be effective, participants must be able to complete them. Identifying factors that predict participation and attrition may serve as a basis for programme improvement.
