Kids in the city study: research design and methodology.

BACKGROUND: Physical activity is essential for optimal physical and psychological health but substantial declines in children's activity levels have occurred in New Zealand and internationally. Children's independent mobility (i.e., outdoor play and traveling to destinations unsupervised), an integral component of physical activity in childhood, has also declined radically in recent decades. Safety-conscious parenting practices, car reliance and auto-centric urban design have converged to produce children living increasingly sedentary lives. This research investigates how urban neighborhood environments can support or enable or restrict children's independent mobility, thereby influencing physical activity accumulation and participation in daily life. METHODS/DESIGN: The study is located in six Auckland, New Zealand neighborhoods, diverse in terms of urban design attributes, particularly residential density. Participants comprise 160 children aged 9-11 years and their parents/caregivers. Objective measures (global positioning systems, accelerometers, geographical information systems, observational audits) assessed children's independent mobility and physical activity, neighborhood infrastructure, and streetscape attributes. Parent and child neighborhood perceptions and experiences were assessed using qualitative research methods. DISCUSSION: This study is one of the first internationally to examine the association of specific urban design attributes with child independent mobility. Using robust, appropriate, and best practice objective measures, this study provides robust epidemiological information regarding the relationships between the built environment and health outcomes for this population.

Understanding the Relationship between Activity and Neighbourhoods (URBAN) Study: research design and methodology.

BACKGROUND: Built environment attributes are recognized as being important contributors to physical activity (PA) engagement and body size in adults and children. However, much of the existing research in this emergent public health field is hindered by methodological limitations, including: population and site homogeneity, reliance on self-report measures, aggregated measures of PA, and inadequate statistical modeling. As an integral component of multi-country collaborative research, the Understanding the Relationship between Activity and Neighbourhoods (URBAN) Study seeks to overcome these limitations by determining the strengths of association between detailed measures of the neighborhood built environment with PA levels across multiple domains and body size measures in adults and children. This article outlines the research protocol developed for the URBAN Study. METHODS AND DESIGN: The URBAN Study is a multi-centered, stratified, cross-sectional research design, collecting data across four New Zealand cities. Within each city, 12 neighborhoods were identified and selected for investigation based on higher or lower walkability and Maori demographic attributes. Neighborhoods were selected to ensure equal representation of these characteristics. Within each selected neighborhood, 42 households are being randomly selected and an adult and child (where possible) recruited into the study. Data collection includes: objective and self-reported PA engagement, neighborhood perceptions, demographics, and body size measures. The study was designed to recruit approximately 2,000 adults and 250 children into the project. Other aspects of the study include photovoice, which is a qualitative assessment of built environment features associated with PA engagement, an audit of the neighborhood streetscape environment, and an individualized neighborhood walkability profile centered on each participant's residential address. Multilevel modeling will be used to examine the individual-level and neighborhood-level relationships with PA engagement and body size. DISCUSSION: The URBAN Study is applying a novel scientifically robust research design to provide urgently needed epidemiological information regarding the associations between the built environment and health outcomes. The findings will contribute to a larger, international initiative in which similar neighborhood selection and PA measurement procedures are utilized across eight countries. Accordingly, this study directly addresses the international priority issues of increasing PA engagement and decreasing obesity levels.

Creating intoxigenic environments: marketing alcohol to young people in Aotearoa New Zealand.

Alcohol consumption among young people in New Zealand is on the rise. Given the broad array of acute and chronic harms that arise from this trend, it is a major cause for alarm and it is imperative that we improve our knowledge of key drivers of youth drinking. Changes wrought by the neoliberal political climate of deregulation that characterised the last two decades in many countries including Aotearoa (Aotearoa is a Maori name for New Zealand) New Zealand have transformed the availability of alcohol to young people. Commercial development of youth alcohol markets has seen the emergence of new environments, cultures and practices around drinking and intoxication but the ways in which these changes are interpreted and taken up are not well understood. This paper reports findings from a qualitative research project investigating the meaning-making practices of young people in New Zealand in response to alcohol marketing. Research data included group interviews with a range of Maori and Pakeha young people at three time periods. Thematic analyses of the youth data on usages of marketing materials indicate naturalisation of tropes of alcohol intoxication. We show how marketing is used and enjoyed in youth discourses creating and maintaining what we refer to as intoxigenic social environments. The implications are considered in light of the growing exposure of young people to alcohol marketing in a discussion of strategies to manage and mitigate its impacts on behaviour and consumption.
