Abstract

BackgroundPositive emotional well-being is fundamentally important to general health status, and is linked to many favorable health outcomes. There is societal interest in understanding determinants of emotional well-being in adolescence, and the natural environment represents one potential determinant. Psychological and experimental research have each shown links between exposure to nature and both stress reduction and attention restoration. Some population studies have suggested positive effects of green space on various indicators of health. However, there are limited large-scale epidemiological studies assessing this relationship, specifically for populations of young people and in the Canadian context. The objective of this study was to examine the relationship between exposure to public natural space and positive emotional well-being among young adolescent Canadians.

MethodsThis cross-sectional study was based upon the Canadian 2009-10 Health Behaviour in School-aged Children Survey with linked geographic information system GIS data. Following exclusions, the sample included 17 249 grades 6 to 10, mostly ages 11 to 16 students from 317 schools. Features of the natural environment were extracted using GIS within a 5 km radius circular buffer surrounding each school. Multilevel logistic regression was used to examine the relationship between the presence of public natural space features include green and blue spaces such as parks, wooded areas, and water bodies and students’ reports of positive emotional well-being, while controlling for salient covariates and the clustered nature of the data.

ResultsOver half of Canadian youth reported positive emotional well-being 58.5% among boys and 51.6% among girls. Relationships between measures of natural space and positive emotional well-being were weak and lacked consistency overall, but modest protective effects were observed in small cities. Positive emotional well-being was more strongly associated with other factors including demographic characteristics, family affluence, and perceptions of neighbourhood surroundings.

ConclusionExposure to natural space in youth’s immediate living environment may not be a leading determinant of their emotional well-being. The relationship between natural space and positive emotional well-being may be context specific, and thus different for Canadian youth compared to adult populations and those studied in other nations. Factors of the individual context were stronger potential determinants.
