Objective: To assess the relative prognostic value of 11 variables including, omega-3, perceived stress, cortisol and sleep duration, in predicting adolescent depression. Design, Setting and Participants: A cross-sectional study of 444 healthy adolescents aged 16-18 years, from 10 schools within the Northern Sydney and Central Coast regions of New South Wales, Australia. Participants provided blood and saliva samples and completed questionnaires. Statistical classification methods were used to model the relationships between the predictors and depression. Main Outcome Measures: relative predictive value of each variable in correctly classifying depression. Results: 6% of boys and 9% of girls were categorised as experiencing …

Sugar Consumption Alters Perception Of And Response To Stress In Undergraduate Students: Understanding The "Freshmen Fifteen", Katherine M Keever

Psychological stress is a common part in everyday life that directly affects the body through the nervous system and neuroendocrine hormones. A perceived stressor leads to the activation of the hypothalamic-pituitary-adrenal (HPA) axis, and the synthesis and release of the glucocorticoid hormone cortisol from the adrenal cortex. Studies have linked the release of cortisol during high-stress periods to an increased intake of sugary and fatty foods, consistent with a suspected glucocorticoid-metabolic-brain- negative pathway, with high sugar consumption leading to lower stress and subsequently cortisol levels. In this study, undergraduate students’ diets were supplemented with either a high sugar drink or …
