Purpose: The purpose of this symposium is to present three international perspectives on the nature of the causal relationship between physical activity and mental health.
Description: There is evidence from randomised trials that exercise improves mental health but not for everyone. A better understanding of how exercise has this effect and for whom will help to design more tailored interventions. The symposium will involve presentations from three different countries which seek to enhance our understanding of how physical activity interventions can improve mental health and well-being.
Chair: Adrian Taylor.
Presenter 1: Eco de Geus. A genetic perspective on regular exercise and mental health in the era of genome wide association studies. This presentation will triangulate various methods for causal inference in the extant literature that support both the existence of causal effects of physical as well as confounding by genetic factors that independently influence participation in regular physical activity and mental health.
Presenter 2: Jeff Lambert. Effects of adding web-based behavioural support to exercise referral schemes on symptoms of depression and/or anxiety. Exploratory findings from the e-coachER study.This presentation will describe the e-coachER intervention, a web-based behavioural support programme designed to augment the effects of usual exercise referral scheme, and its effect on mental health outcomes.
Presenter 3: Marit Sørensen. Longitudinal relations between physical activity, illness symptoms and affect among psychiatric patients (with dual diagnoses) under treatment. This presentation will analyze cross-sectional-, autoregressive- as well as cross-lagged effects between physical activity and symptoms of mental illness, positive/negative affective responses during a ten week intervention.
Discussant: Adrian Taylor.
Results: RCT and prospective studies support the value of physical activity to improve mental health but the effects could potentially be greater with additional support for those less inclined to be physically active.
Conclusions: There is a need to move from a ‘population-based’ to ‘personalized’ intervention strategies using genomic and other information on the likelihood that individuals will increase their physical activity for mental health benefit.
