direct biological processes and lifestyle factors. This study tested the hypothesis that social isolation and loneliness
are associated with less objective physical activity and more sedentary behavior in older adults.
Methods: Wrist-mounted accelerometers were worn over 7 days by 267 community-based men (n = 136) and
women (n = 131) aged 50–81 years (mean 66.01), taking part in the English Longitudinal Study of Ageing (ELSA;
wave 6, 2012–13). Associations between social isolation or loneliness and objective activity were analyzed using
linear regressions, with total activity counts and time spent in sedentary behavior and light and moderate/vigorous
activity as the outcome variables. Social isolation and loneliness were assessed with standard questionnaires, and
poor health, mobility limitations and depressive symptoms were included as covariates.
Results: Total 24 h activity counts were lower in isolated compared with non-isolated respondents independently
of gender, age, socioeconomic status, marital status, smoking, alcohol consumption, self-rated health, limiting
longstanding illness, mobility limitations, depressive symptoms, and loneliness (β = − 0.130,p= 0.028). Time spent in
sedentary behavior over the day and evening was greater in isolated participants (β = 0.143, p= 0.013), while light
(β = − 0.143, p= 0.015) and moderate/vigorous (β = − 0.112, p= 0.051) physical activity were less frequent. Physical
activity was greater on weekdays than weekend days, but associations with social isolation were similar. Loneliness
was not associated with physical activity or sedentary behavior in multivariable analysis.
Conclusions: These findings suggest that greater social isolation in older men and women is related to reduced
everyday objective physical activity and greater sedentary time. Differences in physical activity may contribute to
the increased risk of ill-health and poor wellbeing associated with isolation.
