Emotional memory may be modulated by BDNF Val66Met and 5-HTTLPR polymorphisms. However, the influence of these genetic variants on the overnight retention of emotional memories has not been investigated in humans. Thirty-six healthy female students were selected to participate in this study based on 5-HTTLPR genotype status (L'/L', L'/S', S'/S'). Participants were also genotyped for BDNF Val66Met (Val/Val, Met carriers). We measured recognition performance for positive, neutral and negative images before and after overnight sleep...

MRI workers are occupationally exposed to static and time-varying gradient magnetic fields. While the 24-hour time-averaged exposure to static magnetic fields is about a few mT, the maximum static field strength can be as high as 500 mT during patient setup. Over the past several years, our laboratory has performed extensive experiments on the health effects of exposure of animal models and humans to different sources of electromagnetic fields such as cellular phones, mobile base stations, mobile phone jammers, laptop computers, radars, dentistry cavitrons and MRI...

Insufficient sleep is linked to increased stress and suboptimal self-control; however, no studies have examined stress as a reason for why sleep affects self-control. Moreover, it is unknown if there are individual differences that make people vulnerable to this dynamic. Daily diary entries from 212 university students across 30 days were used in a multilevel path model examining if stress explained how prior night sleep affected next-day self-control difficulties and exploring if individual differences in sleep duration, stress, or self-control qualified this effect...

OBJECTIVE: Sleep insufficiency has been related to self-control failure: people fail to go to bed in time and end up sleep deprived. The role of state self-control in predicting bedtime and sleep duration has not yet been investigated. Based on research claiming an overlap between depleted self-control resources and fatigue, self-control depletion may foster earlier bedtimes. Conversely, self-control depletion also increases the propensity to procrastinate bedtime by giving in to the immediate gratification of late night entertainment...

Mental disorders and sleep dysfunction are common among Chinese university students. This study aimed to evaluate a low cost scalable mindfulness intervention program to improve psychological health and sleep quality among Chinese university students. A randomized controlled trial with 101 university students (mean age 22.30 ± 2.63, 69.31% female) was conducted. Participants were randomized into 4 groups: Group 1: control group (n = 25), Group 2: mindfulness only group (n = 27), Group 3: mindfulness + plain-text reminder group (n = 24), and Group 4: mindfulness + enhanced text reminder with animal meme group (n = 25)...

Sleep deprivation studies have highlighted the importance of adequate sleep for optimal daytime functioning. However, there is limited research exploring whether variations in natural sleep patterns produce similar difficulties to those seen in sleep deprivation studies. The aim of the current study was to explore whether naturalistic reductions in sleep duration and/or sleep quality were associated with behavioural and electrophysiological measures of cognitive control. Sixty undergraduate students were asked to wear an actigraph for 7 consecutive nights before completing a hybrid Flanker-Go/NoGo task whilst continuous EEG data were recorded...

OBJECTIVE: Our objective was to examine the co-occurrence of sleep problems and emotion dysregulation and its short- and long-term links to depressive symptoms and alcohol use in a sample of university students. METHOD: Participants included 1132 first-year university students from Southern Ontario (70.5% women). Time 1 data were collected in February/March, 2010, and Time 2 data (n = 746) were collected in February/March, 2014. Participants were surveyed about sleep problems and emotion dysregulation (Time 1), and depressive symptoms and alcohol use (Times 1 and 2)...

BACKGROUND: Physical literacy is defined as the motivation, confidence, physical competence, and knowledge and understanding to engage in physical activity for life. Physical literacy knowledge and understanding encompasses movement (how to move), performance (evaluation of movement), and health and fitness (value of exercise, need for relaxation and sleep, etc.). This paper describes the development and evaluation of a standardized assessment of physical literacy knowledge and understanding for Canadian children in grades 4, 5, and 6...

Objectives: This study identifies and describes the clustering of 5 behavioral risk factors (BRFs) among university students. We also investigated whether cluster membership is associated with the students' self-rated academic performance and self-rated health. Material and methods: A sample of 1300 undergraduates at 6 universities and 3 colleges in Libya completed a self-administered questionnaire that assessed BRFs (nutrition, physical activity, alcohol consumption, smoking, illicit drug use, inadequate sleep)...

Consumption of energy is a national and international phenomenon that showed increase in market spread and profits from 1990 and made the emergence of many brands. Energy drinks are aggressively marketed with the claim that these products give an energy boost to improve physical and cognitive performance. However, studies supporting these claims are limited. The study examines the new phenomena of energy drinks among university students in Lebanon, based on the participants' personnel characteristics, university grade and the impact on health status...

Androgen deficiency in males has traditionally been predominantly limited to older men aged 50+ years. However, little is known of the correlation between hormonal disruption, stress, and sleep in college-aged males. This cross-sectional study investigates lifestyle behavior patterns in young men and a screening for potential androgen deficiency. A survey of 409 male students, as part of a larger USDA-funded GetFruved study, was analyzed for this subproject. Survey instruments used include the Androgen Deficiency in the Aging Male Questionnaire (ADAM) to assess for inadequate ADAM scores, the Perceived Stress Scale to measure stress levels and the Pittsburgh Sleep Quality Index to evaluate sleep quality...

BACKGROUND: Adolescence obesity has now become an epidemic. In recent years, Internet addiction has been identified as a risk factor for obesity. We aimed to evaluate the role of some mediators such as sleep quality, physical activity and fast food consumption in the relation between internet addiction and Body Mass Index (BMI) among adolescents. STUDY DESIGN: A cross-sectional study. METHODS: Overall, 928 students, aged between 13 and 17 yr, were randomly selected in Behbahan, southwestern Iran from Oct 2017 to Dec 2017...

Nonmedical use of prescription medications is a growing health problem including not only the opioid painkiller overdose epidemic but also benzodiazepine and stimulants misuse. Medical students express considerable high percentages of prescription drug misuse but also of illicit drug use, with cannabis being the frequently used illicit drug. We report the final results of a cross-sectional study among medical students that examined prevalence and motivation for use and suggest that medical students display similar patterns of misuse, for both licit and illicit drugs, to other students...

PURPOSE: University students report high rates of secondhand harm from alcohol (i.e., harm from another person's drinking). The current study investigated the association between students' exposure to secondhand harm and student mental health and university sense of belonging. We also assessed whether students' sense of belonging mediated the association between secondhand harm and mental health and sex differences in these associations. METHODS: A total of 941 students (70% female) completed an online survey...
