“…Electronic screens emit blue light, which can signal blue-light sensitive melanopsin in photo-responsive retinal ganglion cells that it is daytime and, in turn, delay melatonin onset (Henriksen et al, 2016). The adolescent increase in screen usage may act as a SRD event and contribute to BSD mood episodes, and indeed, elevated screen use is associated with depression (e.g., Gunnell et al, 2016). Moreover, blue-light blocking glasses are a promising adjunctive treatment for BSD (Henriksen et al, 2016).…”

The idea that bipolar spectrum disorders (BSDs) are characterized by enhanced sensitivity to rewarding stimuli is at the core of the reward hypersensitivity model, one of the most prominent and well-supported theories of BSDs. In this article, we present the reward hypersensitivity model of BSDs, review evidence supporting it, discuss its relevance to explaining why BSDs typically begin and consolidate during the period of adolescence, and consider three major unresolved issues for this model that provide important directions for future research. Finally, we present integrations of the reward hypersensitivity model with circadian rhythm and immune system models that should provide greater understanding of the mechanisms involved in BSDs, and then suggest additional directions for future research deriving from these integrated models.

“…This is consistent with the 46-country study that found that sleep was positively associated with PA among adult females but not males (Koyanagi et al 2018). It is possible that the relationship between PA and different aspects of wellbeing e.g., psychological distress, life satisfaction and sleep is bidirectional (Gunnell et al 2016;Kline 2014). For example, while poor psychological wellbeing may have a negative impact on PA, insufficient PA also can cause poor psychological wellbeing.…”

Physical activity, sedentary behaviour and psychological wellbeing among young adults in Bangladesh: A one-year prospective study

Background:The transition to young adulthood offers more autonomy in making lifestyle choices, many of which can be unhealthy. Lack of physical activity (PA) and prolonged sedentary behaviour (SB) can have adverse effects on the concurrent and future health and wellbeing of young adults. However, little is known about PA and SB among young adults in low-and-middle-income countries (LMICs), where rapid urban-industrial transformation may promote a sedentary lifestyle and affect wellbeing. Bangladesh is an LMIC with young adults representing one-fifth of the country's population. Major causes of poor health in this age group are attributed to non-communicable diseases and psychosocial disorders. Given the established associations with health and wellbeing, it is essential to understand PA and SB of young adults in Bangladesh. Objectives:To assess the (i) prevalence and sociodemographic patterns of PA and SB, (ii) individual-level correlates of PA, SB, and changes in PA and SB, and (iii) associations of PA and SB with psychological distress and sleep difficulties among university-based young adults in Bangladesh. Design and Methods: A one-year prospective study with two assessment points was conducted to collect data. The self-administered written survey included the Global Physical Activity Questionnaire (GPAQ) to assess PA and SB. Wellbeing was assessed using the Kessler 6 Psychological Distress scale and a single item on sleep difficulties. Data on sociodemographic, health, wellbeing, lifestyle, and environmental factors were also collected.Setting/participants: Participants were undergraduate students aged 18 to 24 years from six universities (3 public and 3 private) in Dhaka city, Bangladesh (Wave 1=573; response rate 92%, 45% female; Wave 2=395). Results:Overall, 17% of participants at Wave 1 and 23% at Wave 2 met the World Health Organization recommendations to do ≥150 mins/week of moderate-to-vigorous PA (MVPA). Significantly more males than females were meeting the recommendations at both waves (Wave 1: 27% vs. 6%; Wave 2: 34% vs. 12%). Median duration of MVPA was significantly higher (p<.0001) for males [120 mins/week] than females [90 mins/week].Jogging/running was the most common recreational PA, with 20% males and 12% females doing this at least once per week. Females participated more in indoor activities (e.g., University Library and, subject to the policy and procedures of The University of Queensland, the thesis be made available for research and study in accordance with the Copyright Act 1968 unless a period of embargo has been approved by the Dean of the Graduate School.

“…Furthermore, due to our study design (cross-sectional), we cannot pinpoint causality. For example, a bidirectional relationship was proposed between screen time and mental health 45 . On the other hand, we adjusted analyses by body mass index, somatic maturation, and physical activity, which are important correlates of mental health 46,47 .…”

“…For example, a bidirectional relationship was proposed between screen time and mental health 45 . On the other hand, we adjusted analyses by body mass index, somatic maturation, and physical activity, which are important correlates of mental health 46,47 . As a first threshold of "risk", we adopted the internationally recommended cutoff for young people (2h/d) 48 , followed by another cutoff widely used in the literature (4h/d) 4 , which also allowed the understanding of gradual relationships.…”

-Aim:To analyze the association between screen-based sedentary behaviors, mental health, and social relationships in Brazilian adolescents. Methods: A representative sample of the adolescents from Londrina/PR was selected (n = 1,158; 10 to 17 y). Weekday and weekend screen time (TV-viewing and computer/video-game), mental health indicators (self-rated health, stress, feelings of sadness, and satisfaction with own body), and perceived social relationships (friends, family, and teachers) were collected through questionnaires. Somatic maturation, body mass index, and physical activity were assessed as covariates. Results: Adolescents who reported higher TV-viewing presented higher odds (p < 0.05) for poor self-rated health (boys), higher stress (both sexes), and dissatisfaction with own body (boys), friendships (girls), and teachers (girls). In contrast, higher computer/video-game use was associated with lower odds (p < 0.05) for poor self-rated health (girls), higher stress (boys), feelings of sadness (both sexes), and dissatisfaction with friends (both sexes) and family (both sexes). Conclusion: While higher TV-viewing is associated with negative outcomes, higher computer/video-game users demonstrate better mental health and lower satisfaction with their social relationships.
