Investigating the Physical Activity Behaviors of Canadian Adults Over Time: Multilevel Sex and Age Group Trajectories Across 2 Decades.

Background: This study explores changes in the leisure-time physical activities of Canadian adults over time.

Methods: Using representative panel data from the National Population Health Survey, multilevel analyses of 13,933 respondents aged 18 and older were performed to assess both overall and individual leisure-time physical activity trajectories from 1994 to 2011 and the extent to which these trajectories differ by sex and age groups.

Results: With the exception of those aged 65 and older, there is evidence that as Canadians age their overall levels of physical activity increase over time.

Exciton Migration and Surface Trapping for a Photonic Crystal Displaying Charge-Recombination Fluorescence.

A compact donor-acceptor molecular dyad has been synthesized by attaching an N,N-dimethylamino fragment to a naphthalic anhydride residue. The dyad shows fluorescence from an intramolecular charge-transfer state (i.e.

Exploring an Olympic "Legacy": Sport Participation in Canada before and after the 2010 Vancouver Winter Olympics.

Guided by the notion of a trickle-down effect, the present study examines whether sport participation in Canada increased following the 2010 Winter Olympics in Vancouver. Comparing rates of sport participation prior to and following the Games using nationally representative data, the results suggest that the Olympics had almost no impact on sport participation in Canada, although there does appear to be a modest "bounce" in sport participation in the Vancouver area immediately following the Vancouver Games. As such, if the trickle-down effect did occur, the analysis suggests that the effect was locally situated, short-lived, and small.

The Enduring Influence of Parent's Voluntary Involvement on Their Children's Volunteering in Later Life.

This study investigates the effect of parent's voluntary involvement on their children's volunteering in later life, and examines the degree to which this effect persists across older age cohorts. To accomplish this, we make use of retrospective questions from the 2010 Canada Survey of Giving, Volunteering and Participating that ask respondents about their experiences in their school-age years. The results show that parental voluntary involvement is positively related to adult voluntary participation, and that the effect of parental voluntary involvement on later volunteerism appears to persist well into adulthood.

Physical capital and the embodied nature of income inequality: gender differences in the effect of body size on workers' incomes in Canada.

This study assesses the effects of body size--measured using the body mass index--on the income attainment of female and male workers in Canada. Using data from a national representative sample of Canadians, multivariate analyses show that, for female workers, the body size-income relationship is negative. However, for male workers, the body size-income relationship is positive and nonlinear.

The dwelling-type choices of older Canadians and future housing demand: an investigation using the Aging and Social Support Survey (GSS16).

Using the 2002 Aging and Social Support Survey (GSS16), multinomial logit regression, and cohort-component projection techniques, this study explored how social support networks, health, and economic characteristics have shaped the residential choices of older Canadians, and predicts how they are likely to do so in the future. It focused on the distribution of 55-to-75-year-olds across three private-dwelling types: general community living, age-restricted housing, and age-restricted housing with nursing care. The analysis shows that social support characteristics are the strongest predictors of dwelling type, meaning that individuals appear to choose their dwellings largely on the basis of their social needs and wants, rather than on their economic or health characteristics.
