We investigate the associations between demographics and program success. The profiles and conversations of students and mentors that participated in the program between 2009 and 2013 were analyzed. Students were categorized into two groups (high and low engagement) based on the number of words written to their mentors. The high group contained proportionally more urban than rural students and equal proportions of Aboriginal and non-Aboriginal students, while the low group contained equal numbers of rural and urban students and proportionally more Aboriginal than non-Aboriginal students. This study provides valuable information on the use of online mentoring in northern communities.

We examined the association between urinary fluoride adjusted for specific gravity (UFSG) and tap water fluoride levels, by age and sex, among individuals living in Canada. Participants included 1629 individuals aged 3 to 79 years from Cycle 3 (2012–2013) of the Canadian Health Measures Survey. We used multiple linear regression to estimate unique associations of tap water fluoride levels, age, sex, ethnicity, body mass index (BMI), use of fluoride-containing dental products, smoking in the home, and tea consumption with UFSG. UFSG concentration was significantly higher among participants who received fluoridated drinking water (mean = 1.06 mg/L, standard deviation = 0.83) than among those who did not (M = 0.58 mg/L, SD = 0.47), p < 0.01. UFSG increased over adulthood (ages 19 to 79). Higher UFSG concentration was associated with being female, tea drinking, and smoking in the home....

In this chapter, we discuss the prevalence of cyberbullying and cybervictimization in Canada, which ranges from 4.5% of university aged youth engaging in cyberbullying at any time (Cunningham et al., 2015) to 33.7% of adolescents in the past three months (Mishna et al., 2010). We explore how these prevalence rates vary according to age, gender, geographic location, and methodological differences between studies. We use Canadian research to identify risk and protective factors according to a social ecological framework, with a discussion of factors at the individual, family, school, and neighborhood level. We then discuss evidence-based interventions aimed to address cyberbullying in Canada, and end with recommendations for how to move the field forward and address the underlying societal dynamics that produce cyberbullying...

We examined the association between fluoride exposure and attention outcomes among youth living in Canada. Method: We used cross-sectional data collected from youth 6 to 17 years of age from the Canadian Health Measures Survey (Cycles 2 and 3). Urinary fluoride concentration adjusted for specific gravity (UFSG) was available for 1877 participants. Water fluoride concentration measured in tap water samples was available for 980 participants. Community water fluoridation (CWF) status was determined by viewing reports on each city's website or contacting the water treatment plant. We used logistic regression to test the association between the three measures of fluoride exposure and ADHD diagnosis. Linear regression was used to examine the relationship between the three measures of fluoride exposure and the hyperactivity/inattention score on the Strengths and Difficulties Questionnaire (SDQ). Results: UF SG did not significantly predict ADHD diagnosis or hyperactive/inattentive symptoms. A 1 mg/L increase in tap water fluoride level was associated with a 6.1 times higher odds of an ADHD diagnosis (95% CI = 1.60, 22.8). A significant interaction between age and tap water fluoride level (p = .03) indicated a stronger association between tap water fluoride and hyperactivity/inattention symptoms among older youth. A 1 mg/L increase in water fluoride level was associated with a 1.5 SDQ score increase (95% CI: 0.23, 2.68, p = .02) for youth at the 75th percentile of age (14 years old). Similarly, there was a significant interaction between age and CWF. At the 75th percentile of age (14 years old), those living in a fluoridated region had a 0.7-point higher SDQ score (95% CI = 0.34, 1.06, p < .01) and the predicted odds of an ADHD diagnosis was 2.8 times greater compared with youth in a non-fluoridated region (aOR = 2.84, 95% CI: 1.40, 5.76, p < .01). Discussion: Exposure to higher levels of fluoride in tap water is associated with an increased risk of ADHD symptoms and diagnosis of ADHD among Canadian youth, particularly among adolescents. Prospective studies are needed to confirm these results.

For this reason, parental expectations of treatment are helpful in considering the nature of parental engagement in the treatment process and possible barriers to treatment. The goal of this study was to better understand the expectations of parents who sought residential treatment for their youth. From 638 potential parent applications, 28 individual applications were randomly selected for in-depth qualitative analysis. The most frequently expressed expectation was for youth to have better relationships with their family and with peers. Implications for treatment program design, effectiveness, and evaluation are discussed.

To address this gap, we review four ethical frameworks for research with Indigenous Peoples in Canada. Drawing upon our experiences conducting a transformative social justice research project in five Indigenous communities, we discuss the ethical tensions we have encountered and how we have attempted to address these challenges. Finally, drawing on these experiences, we make recommendations to support those planning to conduct research with Indigenous Peoples in Canada. We discuss the importance of training to highlight the intricacies and nuances of bringing the ethical guidelines to life through co-created research with Indigenous communities.
