Eating disorders are widespread illnesses with significant impact. There is growing concern about how those at risk of eating disorders overuse online resources to their detriment. We conducted a pre-registered systematic review and meta-analysis of studies examining Problematic Usage of the Internet (PUI) and eating disorders. The meta-analysis comprised n=32,295 participants, in which PUI was correlated with significant eating disorder psychopathology Pearson r=0.22 (s.e.=0.04, p<0.001), body dissatisfaction r=0.16 (s.e.=0.02, p<0.001), drive-for-thinness r=0.16 (s.e.=0.04, p<0.001) and dietary restraint r=0.18 (s.e.=0.03). Effects were not moderated by gender, PUI facet or study quality. Results are in support of PUI impacting significantly on vulnerable populations towards the development or maintenance of eating disorder psychopathology; males may be equally vulnerable to these potential effects. Prospective and experimental studies in the field suggest that small but significant effects exist and may have accumulative influence over time and across all age groups. Those findings are important to expand our understanding of PUI as a multifaceted concept and its impact on multiple levels of ascertainment of eating disorder psychopathology.

“…In each graph, the "Zen" and "Stressed Out" groups are plotted on the left axes; the mean difference is plotted on a floating axis on the right as a bootstrap sampling distribution. The mean difference is depicted as a dot; the 95% confidence interval is indicated by the ends of the vertical error bar Lepp, Barkley, & Karpinski, 2014;Thomée, Eklöf, Gustafsson, Nilsson, & Hagberg, 2007;Thomée, Härenstam, & Hagberg, 2012;Thomée, 2018;Vahedi & Saiphoo, 2018;Zeeni, Doumit, Abi Kharma, & Sanchez-Ruiz, 2018), but most of these effects are small and inconsistent. A recent study by Orben and Przybylski (2019) showed that the effect size of the association between well-being and mobile phone use is very small and might be non-existent in studies with small sample sizes.…”

Mobile phone use in young adults who self‐identify as being “Very stressed out” or “Zen”: An exploratory study

et al. 2020

Previous studies have reported a positive association between mobile phone use and psychological stress. However, the reasons why stressed out individuals use their cell phones more are not clear. To gain further insight on this relationship, we performed secondary analyses on a database of 87 healthy young adults aged 18-35 years who self-categorized themselves as being "Very stressed out" (N = 46) or "Zen" (N = 41). All participants were assessed for psychological stress, duration and nature (hedonistic vs. utilitarian) of mobile phone use, involvement with the mobile phone and levels of nomophobia. Results controlled for the exploratory nature of this study showed that although "Very stressed out" and "Zen" individuals used their mobile phone for the same amount of time and were equally involved with it, "Very stressed out" individuals reported a greater use of their mobile phone for hedonistic purposes and were more nomophobic than "Zen" individuals. The results of this exploratory study suggest that highly stressed out individuals might use hedonistic functions of their mobile phone as a tool to deal with stress, thus explaining why they present greater levels of nomophobia.

“…Finally, we were also able to expand our results to show that HPD rich in BCAA also promote resilience to stress and rescue social avoidance. Associations between life-style choices including diets and psychiatric disorders have been established (Doumit et al, 2016, 2018; Mattar et al, 2019; Quirk et al, 2013; Sanchez-Ruiz et al, 2019; Zeeni et al, 2018). Previous work has implicated prolonged use of both carbohydrate-enriched diets and high fat diets in promoting depression and anxiety, but no information was available about how HPD affect social behavior (Del Rio et al, 2016; Eudave et al, 2018; Hassan et al, 2018; Santos et al, 2018; Xu et al, 2018).…”

How individuals respond to chronic stress varies. Susceptible individuals ultimately develop depression; whereas resilient individuals live normally. In this study, our objective was to examine the effect of branched-chain amino acids (BCAA), commonly used by athletes, on susceptibility to stress. Male C57BL/6 mice were subjected to daily defeat sessions by a CD1 aggressor, for 10 days. On day11, the behavior of mice was assessed using the social interaction test, elevated plus maze and open field. Mice received the BCAA leucine, isoleucine or valine before each defeat session. Furthermore, we examined whether BCAA regulate brain derived neurotrophic factor (BDNF) signaling by using a brain-permeable tropomyosin receptor kinase B (TRKB) inhibitor, ANA-12. We also tested the effect of voluntary exercise and high protein diets on susceptibility to stress. Mice exposed to chronic stress displayed increased susceptibility and social avoidance. BCAA promoted resilience to chronic stress, rescued social avoidance behaviors and increased hippocampal BDNF levels and TRKB activation. Inhibition of TRKB signaling abolished the ability of BCAA to promote resilience to stress and to rescue social avoidance. Interestingly, we found that BCAA activate the exercise-regulated PGC1a/FNDC5 pathway known to induce hippocampal BDNF signaling. Although both voluntary exercise and BCAA promoted resilience to stress, combining them did not yield synergistic effects confirming that they affect similar pathways. We also discovered that high protein diets mimic the effect of BCAA by rescuing social deficits induced by chronic stress and increase Bdnf expression in the hippocampus. Our data indicate that BCAA, exercise and high protein diets rescue susceptibility to stress by activating the hippocampal BDNF/TRKB signaling.
