Interventions for reducing sedentary behaviour in community-dwelling older adults.

Background: Older adults are the most sedentary segment of society, often spending in excess of 8.5 hours a day sitting. Large amounts of time spent sedentary, defined as time spend sitting or in a reclining posture without spending energy, has been linked to an increased risk of chronic diseases, frailty, loss of function, disablement, social isolation, and premature death.

Breaking sedentary behaviour has the potential to increase/ maintain function in frail older adults.

Objectives: This pilot study aimed to evaluate the effect of a sedentary behaviour (SB) reduction intervention (Stomp Out (Prolonged) Sitting (SOS)) in frail older adults.

Methods: Participants (>65years) were recruited from sheltered housing complexes and randomized into 2 groups. On weeks 2, 6 and 10 both groups had face-to-face 40min motivational sessions, including feedback on physical function and SB.

Why Older Adults Spend Time Sedentary and Break Their Sedentary Behavior: A Mixed-Methods Approach Using Life-Logging Equipment.

Older adults are recommended to reduce their sedentary time to promote healthy ageing. To develop effective interventions identifying when, why, and how older adults are able to change their sitting habits is important. The aim of this mixed-method study was to improve our understanding of reasons for (breaking) sedentary behavior in older adults.

Consequences of short interruptions of bouts walking on estimates of compliance to physical activity guidelines.

Current guidelines on physical activity suggest that 30 min of moderate intensity physical activity can be accumulated in continuous bouts of at least 10 min. It has been shown by use of activity monitoring that it is difficult to achieve 10 min of completely uninterrupted walking in the free-living urban environment where we have obstacles such as roads to cross. The aim of this study was to examine the effect of short interruptions in walking on the rate of oxygen uptake (ml · kg · min) to determine if walking with short interruptions can still be considered continuous.

Acceptability of Novel Life Logging Technology to Determine Context of Sedentary Behavior in Older Adults.

Objective: Lifelogging, using body worn sensors (activity monitors and time lapse photography) has the potential to shed light on the context of sedentary behaviour. The objectives of this study were to examine the acceptability, to older adults, of using lifelogging technology and indicate its usefulness for understanding behaviour.

Method: 6 older adults (4 males, mean age: 68yrs) wore the equipment (ActivPAL™ and Vicon Revue™/SenseCam™) for 7 consecutive days during free-living activity.

Exploring the context of sedentary behaviour in older adults (what, where, why, when and with whom).

Background: Older adults are the most sedentary segment of the population. Little information is available about the context of sedentary behaviour to inform guidelines and intervention. There is a dearth of information about when, where to intervene and which specific behaviours intervention should target.

How Sedentary are Older People? A Systematic Review of the Amount of Sedentary Behavior.

Background/objectives: Sedentary behavior (SB), defined as sitting (nonexercising), reclining, and lying down (posture), or by low energy expenditure, is a public health risk independent to physical activity. The objective of this systematic literature review was to synthesize the available evidence on amount of SB reported by and measured in older adults.

Data Source: Studies published between 1981 and 2014 were identified from electronic databases and manual searching.

Prevalence of sedentary behavior in older adults: a systematic review.

Sedentary behavior is a cluster of behaviors adopted in a sitting or lying posture where little energy is being expended. Sedentary behavior is a risk factor for health independent to inactivity. Currently, there are no published systematic reviews on the prevalence of sedentary behavior objectively measured in, or subjectively reported by, older adults.
