This research examined the aetiology of employed mothers' food choice and food provisioning decisions using a qualitative, grounded theory methodology. Semi-structured interviews using the Food Choice Map were conducted with eleven middle-income employed mothers of elementary school-age children. Results demonstrated that the women exhibited conflicting identities with respect to food choice and provisioning. As 'good mothers' they were the primary food and nutrition caregivers for the family, desiring to provide healthy, homemade foods their families preferred at shared family meals. They also sought to be independent selves, working outside the home, within the context of a busy modern family. Increased food autonomy of children, and lack of time due to working outside the home and children's involvement in extracurricular activities, were significant influences on their food choice and provisioning. This resulted in frequently being unable to live up to their expectations of consistently providing healthy homemade foods and having shared family meals. To cope, the women frequently relied on processed convenience and fast foods despite their acknowledged inferior nutritional status. Using Giddens' structuration theory, the dynamic relationships between the women's food choice and provisioning actions, their identities and larger structures including socio-cultural norms, conditions of work and the industrial food system were explored. The ensuing dietary pattern of the women and their families increases the risk of poor health outcomes, including obesity. These results have implications for public health responses to improve population health by shifting the focus from individual-level maternal influences to structural influences on diet.

Objective: The present study describes the trajectory of the energy gap (energy imbalance) in the Canadian population from 1976 to 2003, its temporal relationship to adult obesity, and estimates the relative contribution of energy availability and expenditure to the energy gap. It also assesses which foods contributed the most to changes in available energy over the study period. Design: Annual estimates of the energy gap were derived by subtracting population-adjusted per capita daily estimated energy requirements (derived from Dietary Reference Intakes) from per capita daily estimated energy available (obtained from food balance sheets). Food balance sheets were used to assess which foods contributed to changes in energy availability. Adult obesity rates were derived from six national surveys. The relationship to the energy gap was assessed through regression analysis. Results: Between 1976 and 2003, per capita daily estimated energy availability increased by 18 % (1744 kJ), and increased energy availability was the major driver of the increased energy gap. Salad oils, wheat flour, soft drinks and shortening accounted for the majority of the net increase in energy availability. Adult obesity was significantly correlated with the energy gap over the study period. Conclusions: The widening energy gap is being driven primarily by increased energy availability. The food commodities driving the widening energy gap are major ingredients in many energy-dense convenience foods, which are being consumed with increasing frequency in Canada. Policies to address population obesity must have a strong nutritional focus with the objective of decreasing energy consumption at the population level.

Using the 2005 Canadian Community Health Survey, this study examined how overweight and obesity in Canadian adults are distributed across socio-demographic and geographic groupings. Overweight and obesity prevalence were modeled against socio-demographic indicators using Poisson regression and were assessed geographically using choropleth maps. The Gini coefficient was used to assess the distribution of prevalence across risk groups. The potential impacts of high risk versus population-based prevention approaches on the population prevalence of obesity were also examined. Of adults aged 25 to 64 years, 17% were obese and 53% were overweight or obese, with the highest proportions observed in older age groups, among those who were physically inactive, white or non-immigrant, with low educational levels, and living in the prairie and east coast regions. Recalculation of obesity rates under the different prevention scenarios demonstrated that population-based approaches could achieve a four-fold greater decrease in obesity cases than high risk approaches, highlighting the need for broader population strategies for obesity prevention in Canada.

Abstract. Nineteenth-century somatic theories of madness required specific types of treatment that focused on the body of the afflicted. This treatment stressed the primacy of caring for the body as a route to curing the mind. h a tment through environment would facilitate a transfer of the salubrious nature of a well-ordered place of treatment to the body and the mind of the lunatic. Therefore, the design of this environment became important as a method of treatment. The architect was to construct a facility ensuring the ordering, in detail, of placement, movement, and perception of the incarcerated. Also, this facility would act as a technology to facilitate the limits and types of bodily activities that would define a person as mad or sane. This article focuses on the architectural discourse of building for sanity.R6sum6. Au XIXe sikle, les thhries somatiques de la folie impliquaient des types spkifiques de traitement qui 6taient cent& sur le corps du patient. Ce traitement soulignait l'importance de s'occuper du corps afin de gukir l'espdt. Cette th6rapie qui insistait sur l'environnement du malade prbtendait faciliter le transfert de la salubrite d'un lieu de traitement bien ordonn6 au corps et ? I l'esprit de l'ali6ne. C'est pourquoi la structure architecturale de ces l i e u devint importante en tant que m6thode de traitement. L'architecte devait produire un environnement oh aurait lieu la th6rapie par la rnise en ordre minutieuse de la I place, des mouvements et de la perception du malade incarc6r6.
