Socioeconomic gradients in 24-hour movement patterns across weekends and weekdays in a working-age sample: Evidence from the 1970 British Cohort Study
BACKGROUND: Socioeconomic differences in movement behaviours may contribute to health inequalities. The aim of this descriptive study was to investigate socioeconomic patterns in device-measured 24-hour movement and assess whether patterns differ between weekdays and weekends. METHODS: 4894 individuals aged 46 years from the 1970 British Cohort Study were included. Participants wore thigh-worn accelerometers for 7 days. Movement behaviours were c…
Prognostic accuracy of the one-legged balance test in predicting falls: 15-Years of midlife follow-up in a British birth cohort study
Despite previous observational evidence showing associations between better one-legged balance performance and reduced fall risk, the one-legged balance test had limited prognostic accuracy in predicting recurrent falls. This contradicts ongoing translation of this test into clinical screening tools for falls and highlights the need to consider new and existing screening tools that can reliably predict fall risk

Physical activity and mental well-being under Covid-19 lockdown: A cross-sectional multination study
The findings illustrate the deleterious effects of lockdown on PA, sedentary behavior, and mental health across four Western nations. Australian young and lower middle-aged adults appeared to fare particularly badly in terms of planned PA. The reduction in steps per day is equivalent to the non-expenditure of ~ 100 kcal. Declines in mental health show how harmful lockdowns can be for women in particular
Prevalence and early-life determinants of mid-life multimorbidity: Evidence from the 1970 British birth cohort
Prevalence of multimorbidity was high in mid-life (33.8% at age 46-48) in Britain. Potentially modifiable early-life exposures, including early-life social circumstances, cognitive, physical and emotional development, were associated with elevated risk of mid-life multimorbidity

Psychosocial Stress and Cardiovascular Disease Risk: The Role of Physical Activity
Chronic stress and depression are associated with increased risk of cardiovascular disease and poorer prognosis, and physical (in)activity may be a key underlying biobehavioral mechanism. Physical activity has antidepressant effects, and physically fitter, more active individuals seem to be more biologically resilient to psychosocial stressors. This article will present data from a series of population cohort studies and laboratory-based psychoph…
OP60 Risk of Future Depression in People who Are Obese but Metabolically Healthy: The English Longitudinal Study of Ageing
Background There is some evidence to suggest that obesity is a risk factor for the development of depression, although this is not a universal finding. This discordance might be ascribed to the existence of a ‘healthy obese phenotype’ – that is, obesity in the absence of the associated burden of cardio-metabolic risk factors. We examined whether the association of obesity with depressive symptoms is dependent on the individual’s metabolic health.…
OP17 Do Low Levels of Psychological Distress Predict Mortality? Evidence from an Individual Participant Meta-Analysis of ten Prospective Cohort Studies
Background A series of studies have linked psychological distress (depression and anxiety) with cause-specific mortality, but the risk of lower, sub-clinically symptomatic, levels of distress – hitherto of little interest to specialist mental health practitioners – has not been quantified. Methods We conducted an individual participant meta-analysis of ten large prospective cohort studies from the Health Survey for England. Baseline psychological…
