Inledning: Prevalensen av karies och övervikt/fetma hos barn och ungdomar beskrivs kort. Syfte: Att kartlägga och analysera studier som undersökt sambandet mellan kariesprevalens och BMI hos barn och ungdomar. Följande frågeställningar ska besvaras: Finns det en korrelation mellan kariesprevalens och BMI? Har gruppen överviktiga barn och ungdomar högre kariesprevalens? Har gruppen underviktiga barn och ungdomar högre kariesprevalens? Metod: Frågeställningarna besvaras med hjälp av en systematisk litteraturöversikt. Resultat: Utav sammanställningens 28 artiklar visade 14 på samband mellan karies och BMI och lika många visade inget samband. Tre av de som påvisade samband gjorde detta mellan karies och undervikt.Slutsats: Samband mellan kariesprevalens och BMI har visats i flera studier, medan andra studier inte har kunnat visa detta. Ytterligare studier behövs för att tydligare identifiera vilka faktorer som eventuellt är gemensamma och viktiga för utveckling av både karies och undervikt/övervikt/fetma hos barn och ungdomar. / Introduction: The prevalence of dental caries and underweight/overweight/obesity in children and adolescents are described briefly.Objective: To survey and analyze studies that examined the relationship between caries prevalence and BMI in children and adolescents. The following questions were to be answered: Is there a correlation between caries prevalence and BMI? Does the group of overweight children and adolescents have a higher caries prevalence? Does the group of underweight children and adolescents have a higher caries prevalence?Method: These questions were to be answered by a systematic literature review. Results: In the collection of all articles, it was fourteen that showed a correlation between dental caries and BMI and an equal number who did not show correlation. Of those who indicate a connection, there were three studies that showed a correlation between dental caries and underweight.Conclusion: Correlation between caries prevalence and BMI has been shown in several studies, other studies have not been able to show any correlation. Further studies are needed in the future to more clearly identify the factors that may be common and important for the development of both dental caries and underweight / overweight / obesity in children and adolescents.

School-based body mass index (BMI) screenings seek can improve parents' recall about their child's weight, increase concern about excess weight, and correct parents' misperceptions to help them make informed decisions about their child's health. However, schools have questioned parents' understanding of and attitudes about BMI, and have expressed concern about parents' reactions to BMI reports. Using a sample of school nurses (n=7) and parents/guardians (n=125) from the School District of Philadelphia (SDP), this research addressed these concerns by clarifying: 1) parents'/guardians' perceptions and knowledge about BMI; 2) the challenges schools face in communicating with parents/guardians; and 3) the messages that can be communicated to parents/guardians to help them understand their child's BMI-for-age category and why their child's BMI is measured in his/her school. The research used framing theory and perceptual mapping methods to study and improve communication about BMI to parents/guardians in the School District. The four-phase study design incorporated qualitative (focus groups and semi-structured in-depth interviews) and quantitative (cross-sectional survey) methods to assist in the development of an evidence-informed BMI report card template for the SDP. Messages were constructed to meet the needs of four distinct groups of parents/guardians that emerged from the factor and cluster analyses - "Passive Parents," "Neutral Parents," "Confident Advocates" and "Active Worriers." Although each cluster of parents/guardians had their own unique perceptions and varying degrees of assuredness and confidence related to BMI concepts, the majority of parents/guardians in this study shared common favorable perceptions about BMI measures, school-based screening programs and BMI report cards. / Public Health

Currently, two-thirds of adults and one-half of children and adolescents in the United States meet criteria for overweight or obese weight status (Wang & Beydoun, 2007). While weight loss often is desired among these individuals, few achieve sustained weight loss maintenance. A model of motivation, affect, and long-term weight loss maintenance is proposed, based on Carver's model of behavior change (2004b) and related research. This investigation evaluated the model's proposed associations between approach and avoidance motivation, depressive and anxious affect, and caloric consumption within the context of a dietary lapse condition in the laboratory. Findings did not support the hypotheses that avoidance motivation would be negatively related to calorie consumption or that approach motivation would be positively associated with calorie consumption. Conversely, higher avoidance motivation was found to predict higher caloric consumption. Finally, this relationship was not mediated by depressive or anxious affect. Instead, consumption of high calorie foods alone was shown to fully mediate this relationship. Recommendations for future research are presented in the context of these findings. / Psychology

Introduction: The homeostatic role of the endocannabinoid system (ECS) is mediated through the actions of endocannabinoids. Intake of exogenous cannabinoids found in Cannabis sativa alter the function of the ECS which may then impact other organ systems. Use of cannabis has been inconsistently linked to adverse cardiometabolic outcomes. Rates of cannabis use are high among patients with psychiatric conditions who are already at higher risk of cardiometabolic diseases when compared to the general population. Cannabis use patterns and cardiometabolic risk variables in this population need further study to clarify the links between use and outcomes. Methods: Patients with psychiatric conditions from the St. Joseph’s Healthcare Hamilton Hospital were enrolled into the Cannabis and Physical Health study. Sociodemographic data, medical history, cigarette use, and cannabis use patterns were collected. In addition, cardiometabolic profile data were collected including body mass index, blood pressure, lipids, and HbA1c. Multivariable regression analyses were conducted, and a Bonferroni correction applied. Results: This cross-sectional study enrolled 200 patients (female: n=86, 43.0%), 18 years of age and older. Among 79 cannabis users (female: n=34, 43.0%), the majority (n=53, 67.1%) consumed cannabis daily and had a diagnosis of a moderate cannabis use disorder (CUD; n=57, 72.2%, CUD score = 4.3 ± 3.4). Use of cannabis was initiated on average at 15.2 ± 3.5 years of age and used for an average of 13.5 ± 11.0 years. There was no association between cannabis use and cardiometabolic risk factors when adjusted for age, sex, psychiatric diagnosis, antipsychotic medication use, and cigarette smoking (P>0.006 for all outcomes). Conclusions: Our findings indicate that in this sample of patients with psychiatric diagnoses, patients who use cannabis had a similar cardiometabolic profile to non-users. Patterns of cannabis use highlight the importance of reducing cannabis consumption and preventing or slowing the progression of CUD in this population, as well as limiting adolescent exposure to cannabis. / Thesis / Master of Science (MSc) / The endocannabinoid system regulates several processes in the body via endocannabinoid signaling, and cannabinoids found in cannabis can change endocannabinoid system function. Cardiovascular events and changes in appetite have been noted with cannabis use, and this is especially important in some vulnerable populations at risk of increased cannabis use; one of these groups include patients with psychiatric conditions who tend to use cannabis but also already have an increased cardiometabolic risk. In this thesis, the relationship between cannabis use and cardiometabolic risk was examined in 200 patients, and patterns and determinants of cannabis use explored. Our results demonstrated that of the 79 cannabis users, most consumed cannabis daily, and had a moderate cannabis use disorder. On average, users began cannabis consumption at 15 years of age and for an average duration of 14 years. Moderate cannabis use was not related to cardiometabolic risk in these patients. Our data demonstrate the need to prevent or slow the progression of cannabis use disorder in these patients and the importance of reducing early exposure of adolescents to cannabis.

Background: Overweight and obesity affect approximately one-third of Canadian children and these children are at an increased risk of developing life-long obesity-related health consequences. Treatment efforts in the pediatric setting focus on behavioural modification – including modification of dietary intake. Eating behaviours encompass a modifiable aspect of dietary intake and could be a useful approach for weight reduction in the context of pediatric weight management (PWM) programs. Objectives: 1) To describe changes in family, child and parent eating behaviours over a 12-month period after enrolment in a PWM program. 2) To examine if changes in family eating behaviours over the first 6 months in a PWM program can predict child BMI z-score at 12 months, even when controlling for other factors related to changes in BMI z-score. Methods: Children ages 2-17 with a BMI >85th percentile were included in this analysis. Data was collected at baseline, 6 month and 12-month timepoints as part of the CANadian Pediatric Weight management Registry. BMI z-score was derived from height (cm) and weight (kg). Eating behaviours (eating related to hunger (ERH) and eating style (ES)) were measured in children, parents and families using the Family Eating and Activity Habits Questionnaire. Child and parental scores were summed to generate a family score. Decrease in scores over time indicated improvements in eating behaviours. Results: 807 children were included in the analysis (48.3% male, 51.7% female, mean age 12.08, mean baseline BMI z-score 3.55). Family ERH scores decreased significantly from baseline to 6 months by 1.63% (-0.16 points, SD=0.09, p<0.05) but by 12 months scores were the same as at baseline. Child ERH scores decreased significantly by 2.06% at 6 months (-0.14 points, SD=0.02, p<0.05), but at 12 months scores were the same as at baseline. Parent ERH scores did not change significantly. Family ES scores decreased from baseline to 6 months by 1.88% (-1.99 points, SD=0.21, p<0.05) and stayed approximately the same at 12 months. Child ES scores were similar, decreasing 2.86% (-1.68 points, SD=0.03, p<0.05) from baseline to 12 months. Parents ES score decreased significantly by 6 months, but after 12 months, scores were the same as at baseline. Change in either family eating behaviours from baseline to 6 months did not predict child BMI z-score at 12 months when adjusting for age, sex and BMI z-score at baseline. In subsequent exploratory analysis, increases in child eating behaviour scores at 6 months was a significant predictor of increases in child BMI z-score at 12 months (p=0.02) when adjusting for age, sex and BMI z-score at baseline. Conclusion: In the context of PWM programs, eating style and eating for hunger improved over the first 6 months after enrolment. Improvements in child eating behaviour after 6 months could predict improvements in child BMI z-score after 12 months. / Thesis / Master of Science (MSc)

Yes / We examined whether visual processing mechanisms of the body of conspecifics are different in women and men and whether these rely on westernised socio-cultural ideals and body image concerns. Twenty-four women and 24 men performed a visual discrimination task of upright or inverted images of female or male bodies and faces (Experiment 1) and objects (Experiment 2). In Experiment 1, both groups of women and men showed comparable abilities in the discrimination of upright and inverted bodies and faces. However, the gender of the human stimuli yielded different effects on participants’ performance, so that female faces, and male bodies appeared to be processed less configurally than female bodies and male faces, respectively. Interestingly, the reduction of configural processing for male bodies was significantly predicted by participants’ Body Mass Index (BMI) and their level of internalization of muscularity. Our findings suggest that configural visual processing of bodies and faces in women and men may be linked to a selective attention to detail needed for discriminating salient physical (perhaps sexual) cues of conspecifics. Importantly, BMI and muscularity internalization of beauty ideals may also play a crucial role in this mechanism.
