The Effect of Sedentism on Mental Wellbeing WorldWellbeingWeek WorldWellbeingWeek20220 Wellbeing
By Hidaya Aliouche, B.Sc.Reviewed by Sophia Coveney Sedentary behavior, defined as activities that require minimal to no body movement, which consequently result in low energy expenditure, has emerged recently as a potential indicator of both physical and mental health in adult populations. There is an association between sedentary behavior and mental health issues including depression, anxiety, and self-esteem.
Another report demonstrated a positive effect of light activity on mental health. This finding was corroborated by a UK survey which demonstrated that negative mental health outcomes, including anxiety, were negatively associated with moderate daily physical activity. The mechanistic basis that underpins the correlation between sedentary behavior and depression is thought to include the blocking of direct communication and reduction in social interactions, or the reduction in available time to engage in physical activity which is known to increase overall sense of wellbeing and reduce risk of depression.
Effects of COVID-19: Sedentism and wellbeing outcomes A recent study conducted in the United Kingdom in response to COVID-19 investigated the association between physical activity and sitting time on adults' mental health as well as the influence of potential mediators and confounding variables. The researchers conducted an online survey between May and June 2020. 284 participants self-reported physical exercise, sitting time and mental health, through validated questionnaires.
In addition, though there is a strong association between mental health and sedentary behavior, no studies have yet investigated the moderation effect of physical activity on the impact of sedentary behavior on the outcomes for mental health. Some evidence suggests that higher volumes of physical activity, that is between 60 and 75 minutes per day, can protect against an increased risk of mortality as a consequence of prolonged sitting .

Polyphenic risk score shows robust predictive ability for long-term future suicidality - Discover Mental HealthSuicides are preventable tragedies, if risk factors are tracked and mitigated. We had previously developed a new quantitative suicidality risk assessment instrument (Convergent Functional Information for Suicidality, CFI-S), which is in essence a simple polyphenic risk score, and deployed it in a busy urban hospital Emergency Department, in a naturalistic cohort of consecutive patients. We report a four years follow-up of that population (n = 482). Overall, the single administration of the CFI-S was significantly predictive of suicidality over the ensuing 4 years (occurrence- ROC AUC 80%, severity- Pearson correlation 0.44, imminence-Cox regression Hazard Ratio 1.33). The best predictive single phenes (phenotypic items) were feeling useless (not needed), a past history of suicidality, and social isolation. We next used machine learning approaches to enhance the predictive ability of CFI-S. We divided the population into a discovery cohort (n = 255) and testing cohort (n = 227), and developed a deep neural network algorithm that showed increased accuracy for predicting risk of future suicidality (increasing the ROC AUC from 80 to 90%), as well as a similarity network classifier for visualizing patient’s risk. We propose that the widespread use of CFI-S for screening purposes, with or without machine learning enhancements, can boost suicidality prevention efforts. This study also identified as top risk factors for suicidality addressable social determinants.
