Where we live can influence our health and behaviours, and in particular our risk of being obese. Obesity is linked to our levels of physical activity, but it is also linked to our sleep quality and to our levels of stress. We will study the extent to which obesity in youth is related to factors that influence day time activities, (e.g. being less active due to living in less walkable neighbourhoods), or to factors predominantly related to night time circumstances (e.g. having poor quality sleep due to living near noisy streets). We will also try to better capture actual behaviours, surroundings and influences using technology such as global positioning systems, noise sensors, motion sensors and satellite images.

Asthma and obesity are important public health priorities that currently affect 15-20% of youth. Both are socially patterned conditions, with the likelihood of being obese or of having asthma differing from one neighbourhood to the next. More recent studies conducted among youth with asthma have observed a great deal of neighbourhood differences in asthma control, considered to be the worldwide standard for monitoring the adequacy of asthma management. In contrast to obesity, however, comparatively few studies have sought to identify specific factors explaining neighbourhood-level differences in asthma control, and little is known about the specific dimensions within built and social environments could be targeted to help improve asthma control. In this study, we examine three dimensions of neighbourhood context believed to affect asthma control: air quality (i.e. traffic related pollutants), built environment (i.e. walkability), and social environment (i.e. area deprivation). We also examine if obesity increases vulnerability to an adverse neighbourhood environment, in a population of asthmatic youth. Our objectives will be pursued using a database comprising a large clinical population of youth diagnosed with asthma, many of which were followed over time. Data from individual patient records and on medication use have already been collected; the current proposal will construct and merge a new database containing indicators of the three neighborhood dimensions of interest. These indicators will be created for several neighbourhood boundaries to allow sensitivity analyses, and over several time points, to capture change over time. We then examine spatial variation in the relationships of interest, and identify which specific neighbourhood characteristics may be involved. This unique infrastructure will also allow us better understand the relationship between asthma, obesity, and neighbourhood context, providing a basis for developing environmental interventions.
