The purpose of this study was to explore associations between early-life factors and the development of youth onset type 2 diabetes mellitus (T2DM). Until 1990, T2DM was seldom reported in youth, however rates of youth onset T2DM are rising worldwide. This retrospective case-control study utilized repository data housed at the Manitoba Centre for Health Policy to review perinatal exposures of Manitoba youth with and without T2DM. The mean age at time of diagnosis was 13.1 years and 61% of youth onset T2DM cases were female. The majority of youth with T2DM resided in rural areas at time of diagnosis. This study found a 14-fold increase in the risk of youth onset T2DM when the mother had pre-gestational diabetes, and 6.5-fold increase in that risk if the mother had gestational diabetes. Breastfeeding was found to be protective, and a lower income quintile at time of birth was found to be more significantly associated with the development of youth onset T2DM than increasingly higher income quintiles . The findings emphasize that efforts aimed at preventing T2DM in youth must begin in the pre-conception period and continue throughout pregnancy.

This dissertation utilizes a Foucauldian perspective to explore the relationship between at-risk youth and the acceptance and integration of long-term conventional goals and values held by the general population. I posit that orthodox theories, which argue that youth who engage in delinquent behaviors do so because they either reject the goals and values of society, or they realize they have no legitimate means of goal attainment, fail to adequately explain why some youth appear to integrate and strive for these goals. I argue that Foucault's work on power and knowledge, more specifically the use of bio-power and the technologies of normalization, can be used as an explanation for how at-risk youth come to integrate and accept these conventional goals and fully participate in the creation of themselves as "docile bodies". This issue is explored through an analysis of two sets of data collected through the development and implementation of two separate surveys; one given to the general population of youth and the other to at-risk youth. As well, I explore the findings of personal interviews collected with youth incarcerated in Kilburn Hall, a remand centre in Saskatoon, Saskatchewan. What these data show is that, far from rejecting the conventional goals and values of society, at-risk youth appear to integrate both the goals and a strong ideology of personal responsibility for the attainment, or failure to achieve these goals.

Background: Physical activity (PA) reduces visceral adipose tissue (VAT) in adults; however, the dose to reduce VAT in youth is unclear. Objective: To examine whether high intensity PA preferentially reduces waist circumference (WC) and VAT compared to lower intensity PA. Design: Randomized controlled trial. Participants: Youth were 13-18yrs, overweight, with one additional risk factor for type 2 diabetes (T2DM). Intervention: 6-months, exercising 3 times/week at a high intensity (70-85% of Heart Rate Reserve HRR), or low intensity (40-55% HRR). Primary outcome: VAT (cm2) measured by MRI at L4-L5, and WC at the height of the iliac crest (cm). Results: 94 Youth were randomized to either high intensity (n=30); low intensity (n=32) or control (n=32). Changes in WC and VAT were not significant across groups. A trend towards a reduction in VAT in the training groups, compared to controls was demonstrated in sub-analysis (-14.3 ± 9.6 % vs. +0.01 ± 0.4 %, p= 0.059). Peak fitness increased significantly in both the high and low intensity arms (1.3 ± 0.6 and 1.4 ± 0.6 ml/kg/min, p < 0.05). Conclusions: Training at 55-65% HRR improves fitness by ~10%, and ~2 days/week elicits modest non-significant reductions in VAT in overweight youth.

Eating disorders are known for their chronic and relapse-ridden course. The cyclical nature of these disorders poses not only grave physical and mental health risks for the sufferer; it also presents serious challenges for the treating professionals and places a high demand and cost on the health care system. In spite of extensive research, no reliable predictors of long-term EDs have been identified in either adult or adolescent populations, nor have treatments emerged that are specifically targeted towards treating those with a long-term ED. It is fundamental to understand who is at risk and what factors are involved in long-term EDs, as the clinical and treatment implications gleaned from this evidence could be quite impactful. The current project will include three studies that will explore long-term EDs in a large transdiagnostic sample of adolescents with an ED. It will also attempt to overcome methodological limitations associated with past studies of this type, and apply an operational definition of this course of illness that may provide a more reliable and valid method with which to identify these cases. As such, the use of the term refractory ED, defined as a return to same-type treatment, will be applied to best identify this group. The three studies proposed in this research project will provide long overdue information on predictors, profiles and growth trajectories of those adolescents who suffer from a refractory course of an ED. This research project attempts to answer the question of: who will be affected, and how will the individual be affected by a refractory ED. With the ability to identify these cases and how the course of illness is being affected, treatment approaches can better aim to provide the appropriate treatment to those individuals most at risk of suffering from a refractory course of illness.

This research explores the experiences and needs of five young people with FASD in care. Data was gathered through personal interviews with youth in care, guided by an anti-oppressive research philosophy. The findings suggest that youth in care with FASD experience a myriad of challenges throughout their journeys in care with regard to placements, caregivers, and the transition to adulthood for which the impact for young people was difficult to understand. The high degree of secondary disabilities of FASD was found to be alarming in this group of young people. The study also found that those with more of an awareness of their disability had the capacity to speak to some of their support needs. All of the youth revealed strengths within themselves and reported having goals and dreams for their futures. A number of recommendations, which include input from participants, are highlighted, with the intention of providing some suggestions for best practice with our young people with FASD in care and policy changes within the systems working with this population.

This thesis explores the ways in which the ‘at-risk’ designation of marginalized and disadvantaged youth within youth-serving agencies contributes to a program of governance within a neoliberalized welfare state. I argue that while there is considerable resistance to the risk designation within youth-serving agencies, officially accepting funding for programming designed to target at-risk youth continues to individualize the troubles youth face and responsibilizes youth to become their own risk managers. Through these structural funding constraints, youth-serving agency staff inadvertently disseminates expert knowledges that validate the notion of ‘at-risk’ youth as a growing problem while legitimating the perspective that social problems can and should be addressed through individual treatment rather than social policy. This both disciplines youth to become better liberal subjects while leaving structural constraints unaddressed. I conclude with some examples of resistance that show promise of working outside of these technologies of governance.

For immigrant and refugee youth, the experience of migration presents significant life changes in their environments, communities, and interpersonal affiliations (Kilbride, Anisef, Baichman-Anisef & Khattar, 2001). Before immigrating to Canada, some refugee youth experienced horrific events that can be traumatic to the fragile identities and sense of belonging of developing children and adolescents. Once in Canada, loneliness, isolation, language deficits, different cultural practices, and in some cases different skin colors may isolate refugee youth and thus jeopardise their sense of belonging in their new country. This study investigated a sense of belonging of war affected refugee youth during their pre-migration and post-migration periods, as well as the factors that may enhance or hinder their sense of belonging. Fifteen participants were interviewed and their responses clearly indicated their desire and need to belong in their new country, to be liked, loved, respected, included, and be part of their new society. Recommendations on how educators can support their quest for belonging and inclusion are discussed.
