The adolescent transition involves a number of changes that for many adolescents result in increased negativity, heightened emotional reactivity, and risk for internalizing symptoms. The purpose of the present set of studies was to examine the role that emotional awareness has in relation to emotion regulation and to subsequent mood symptomatology in adolescence. The first study tested the hypothesized relationship between emotional awareness and emotion regulation, specifically, that emotional awareness is a necessary precursor to adaptive regulation efforts. This study examined the direct and indirect effects of emotional awareness on internalizing symptoms by exploring the extent to which certain emotion regulation strategies influence this relationship. The purpose of the second and third studies was to examine the association between emotional awareness and emotion regulation as measured by changes across three emotional response domains: 1) physiological arousal, 2) self-reported experience, and 3) observed expression during an ecologically valid emotion elicitation task. Participants in these studies were identified as alexithymic or non-alexithymic. Alexithymia involves difficulty identifying and describing emotions and has been used to classify individuals with extremely low emotional awareness. The second study examined the effects of alexithymia on the three emotional response domains in adolescents. Because of the high prevalence rates of alexithymia during adolescence, it could be an important vulnerability factor to help explain increases in internalizing symptoms during the adolescent transition. The purpose of the third study was to examine how patterns of decoupling between physiological arousal, self-reported experience, and observed expression were related to depressive and anxiety symptoms in alexithymic individuals. Overall, findings confirmed that emotional awareness is an important precursor to adaptive emotion regulation efforts. In addition, emotion regulation emerged as a more proximal mechanism in the development of depressive and anxiety symptoms in individuals with low emotional awareness. At a theoretical level, this research has guided our understanding of emotional processing and regulation. At a practical level, results from this program of research will help guide intervention and treatment approaches for adolescents with low emotional awareness. / Thesis (Ph.D, Psychology) -- Queen's University, 2013-05-30 23:32:00.87

A Research Report submitted to the School of Public Health, Faculty of Health Sciences, University of the Witwatersrand, in fulfillment of the requirements for the Degree of Masters in Epidemiology and Biostatistics. Johannesburg, February 2014 / Background: Overweight continues to be a major indicator of adulthood non-communicable diseases (NCDs) risk and can be linked to early childhood and adolescent dietary lifestyles. Research has shown that the burden of childhood and adolescent overweight in sub-Saharan Africa (SSA) and especially in South Africa is rising. There is therefore an urgent need to address this burden in the context of overweight risk related to nutrition transition. The current study used Birth to Twenty (BT20) cohort study data to examine the association between dietary intake and overweight status of 17-year old adolescents residing in Soweto, South Africa in 2007/2008. Methods: A secondary data analysis was conducted including 227 seventeen-year old adolescents (43.6% boys) from the BT20 cohort study. A modified quantitative Food Frequency Questionnaire (FFQ) was used to estimate dietary intake. Height and weight were measured by trained research assistants and overweight was categorized using the International Obesity Task Force (IOBTF) cut-offs. A multinomial logistic regression model was used to examine the association between overweight category (BMI) and dietary intake, socio-demographic factors and other covariates. The base reference used for Body Mass Index (BMI) category was normal weight. Results: The overall overweight prevalence was 14.5% (33/227), and prevalence of underweight was 23.3% (53/227) among the 17-year old Soweto adolescents. The prevalence of overweight was significantly higher in girls (19.3%) than boys (8.1%). The prevalence of underweight was 33.3% for boys and 15.6% for girls. The univariate analysis found the following macronutrient intake positively associated with boys’ BMI category: fat 189.4g (IQR=119.9-239.8, P<0.001), proteins 154.6g (IQR = 98.7-198.2, P<0.001) and carbohydrate 673.1g (IQR = 461-794.2, P<0.001). The following macronutrients: fat 176.4g (IQR = 99.5-220.1, P<0.001), proteins 126.1g (IQR = 70.4-145, P<0.001.) and carbohydrates 523.1g (IQR = 326.6-640.9, P<0.001) were positively associated with girls’ BMI category. The socio-demographic factors found associated with girls’ BMI were ethnicity (p=0.042) and maternal education (p=0.05). Also factors such as washing machine ownership (p=0.046), and parents having a car (p=0.048) were positively associated with boys BMI category. The multinomial logistic regression showed no significant differences in dietary intake when overweight boys were compared to normal weight boys: fat intake (RRR=0.99, 95% CI=0.95-1.01), carbohydrate (RRR=0.99, 95% CI=.96-1.01) and energy intake (RRR=1.01, 95% CI=0.99-1.01). Similar non significant results were observed for girls: fat intake (RRR=1.0, 95% CI =0.96-1.01), carbohydrate (RRR=1.0, 95% CI =0.99-1.02) and energy intake (RRR=1.0, 95% CI=0.99-1.01). Girls from the coloured community were more likely to be underweight than black African girls (RRR= 2.8, 95% CI=0.89-8.57). The results also showed that girls from mixed ancestral community (RRR= 0.25, 95% CI=0.05-1.20) were less likely to be overweight than black African girls. Discussion and Conclusion: The survey indicated high prevalence of both underweight and overweight among 17 year old adolescents residing in Soweto. This underscores the urgent need for both underweight and overweight prevention interventions and also highlights the need for an integrated surveillance system for both underweight and overweight among South African adolescents.
