METHODS Forty studies met the selection(More)
BACKGROUND Physical activity is an essential element in reducing the prevalence of obesity, but much is unknown about the intensity and location of physical activity among youth-this is important because adolescent health behaviors are predictive of behaviors in adults. PURPOSE This study aims to identify the locations where youth moderate-to-vigorous(More)
BACKGROUND Empirical data on laboratory-confirmed seasonal influenza is limited by very low and possibly non-systematic case ascertainment as well as geographical variation. OBJECTIVE To provide a visual representation of an influenza epidemic at the community and regional level using empirical data and to describe the epidemic characteristics. METHODS(More)
BACKGROUND As observed during the 2009 pandemic, a novel influenza virus can spread globally before the epidemic peaks locally. As consistencies in the relative timing and direction of spread could form the basis for an early alert system, the objectives of this study were to use the case-based reporting system for laboratory confirmed influenza from the(More)

This study examined rates of physical activity (PA) and diet quality (DQ) among youth in grades 7 to 9 in Halifax, Nova Scotia, during the 2008/09 school year and tested differences among students in rural,(More)
The obesity epidemic requires the development of prevention policy targeting individuals most likely to benefit.

There were 172,373(More)

Associations between social and material deprivation and mortality from all causes of death--a measure of population health, have been described for(More)
BACKGROUND Bladder and kidney cancers are the ninth and twelfth most common type of cancer worldwide, respectively. Internationally, rates vary ten-fold, with several countries showing rising incidence. This study describes the spatial and spatio-temporal variations in the incidence risk of these diseases for Nova Scotia, a province located in Atlantic(More)
