Article Synopsis
  • Longitudinal cohort studies are crucial for understanding how various factors impact health by tracking participants over time, but maintaining participant engagement over decades is challenging.
  • This study examined participant engagement and involvement (PEI) practices in different cohort studies across Europe, Australia, and New Zealand, using interviews to gather insights on recruitment, consent, communication, and data collection.
  • Findings revealed diverse recruitment strategies, a shift towards digital data collection methods, and attempts to involve participants in decision-making through advisory panels, although success varied by age and socio-economic status.

The influence of global climate change on temperature-related health outcomes among vulnerable populations, particularly young children, is underexplored. Using a case time series design, we analysed 647,000 hospital admissions of children aged under five years old in New Zealand, born between 2000 and 2019. We explored the relationship between daily maximum temperatures and hospital admissions across 2139 statistical areas.

Background: As a key aspect of poverty, material hardship describes day-to-day struggles in affording necessities. In explorations of policy initiatives that mitigate material hardship, evidence suggests direct income support can be effective in alleviating hardship. However, research investigating the long-term effects of income supports is limited, and it remains uncertain as to how benefit receipt may mitigate material hardship for families with children across time.

To test the transmission of mental health difficulties from mother to child, we examined mediation through emotion reminiscing conversations and child language. Maternal depression symptoms were measured at 9 months post-partum, and child mental health outcomes were measured at age 8 years. Emotion reminiscing conversations between 1,234 mother-child pairs (624 boys, 610 girls) were recorded as part of a large, diverse, longitudinal cohort .

Background: Many people fear failure and making mistakes. This fear can be transmitted from parents to children, suggesting that parental communication regarding failures and setbacks may play a critical role in shaping a child's perception of mistakes.

Aims: In this study, we investigated how everyday parent-child conversations about setbacks influence children's fear of making mistakes.

The biological mechanisms that explain how adverse early life events influence adult disease risk are poorly understood. One proposed mechanism is via the induction of accelerated biological aging, for which telomere length is considered a biomarker. We aimed to determine if maternal depression pre- and post-partum was associated with telomere length in children at 4 years of age (n = 4299).

There is increasing interest in the potential long-term outcomes of participation in contact and collision sports, driven by evidence of higher rates of neurodegenerative diseases among former athletes. Recent research has capitalised on large-scale administrative health data to examine health outcomes in contact sport athletes. However, there is limited research on outcomes associated with participation in rugby union, a contact sport with a relatively high incidence of head trauma and musculoskeletal injuries.

Aim: Approaches to understanding child injury tend to focus on short-term proximal influences. Previous analyses have found higher rates of injury among Māori and Pacific children in Aotearoa New Zealand (NZ). This study aimed to investigate how combinations of situations and multiple events act across the life-course to either protect preschool children from, or place them at risk of, repeated injuries requiring medical attention.

Maternal depressive symptoms (MDS) in the postnatal period may impact children's later development through poorer quality parent-child interactions. The current study tested a specific pathway from MDS (child age 9 months) to child receptive vocabulary (4 ½ years) through both self-reported and observed parent-child verbal interactions (at both 2 and 4 ½ years). Participants ( = 4,432) were part of a large, diverse, contemporary pre-birth national cohort study: .

The way that mothers talk about the past (reminisce) with young children is linked to key memory, language, and socioemotional outcomes. The present research explored the role of a range of child, maternal, socioeconomic, and cultural factors that predict maternal reminiscing style, with a particular focus on maternal personality and child temperament. A total of 1,404 mother-child dyads from the prebirth longitudinal cohort study (https://www.

There is growing interest in child socio-emotional competence from parents, educators, employers and policy makers, with emphasis on developing it as early as possible. The aim of the present study was to examine contextual and proximal factors that influence socio-emotional competence development across the first five years of a child's life. We used data from 3200 mothers and their children drawn mostly from four major data collection waves (antenatal, 9 months, 2 years and 4.

Background: Linking self-reported data collected from longitudinal studies with administrative health records is timely and cost-effective, provides the opportunity to augment information contained in each and can offset some of the limitations of both data sources. The aim of this study was to compare maternal-reported child injury data with administrative injury records and assess the level of agreement.

Methods: A deterministic linkage was undertaken to link injury-related data from the Growing up in New Zealand (GUiNZ) study to routinely collected injury records from New Zealand's Accident Compensation Corporation (ACC) for preschool children.

We investigated the association between persistence and change in behavioral difficulties during early to middle childhood and several cognitive outcomes. We observed 3904 8-year-olds enrolled in the longitudinal study Growing Up in New Zealand (50% male/female; 23% Māori, 9% Pacific Peoples, 13% Asian, 2% Middle Eastern/Latin American/African, 9% Other, 43% European). The NIH Toolbox Cognition Battery was used to assess cognitive functioning at 8 years and the Strengths and Difficulties Questionnaire for behavioral difficulties at 4.
