Device‐measured physical activity and sedentary time are suggested to be more important determinants of all‐cause mortality compared to body mass index (BMI) in mainly older adults. However, the joint associations of physical activity and sedentary time with BMI in relation to mortality risk in relatively healthy middle‐aged individuals are unclear...

Physical inactivity is recognised as a major public health problem. In Sweden about 1/3 of the adult population reports being insufficiently active. A central task in public health work is to support the individual, without blaming, in making healthy choices. Initiatives in healthcare, such as counselling on physical activity, have been shown to be...

Recommendations on physical activity and sedentary behaviour for improved health have been prepared by Professional Associations for Physical Activity (YFA) and approved by the Swedish Society of Medicine. All adults should do aerobic physical activity 150-300 minutes at moderate or 75-150 minutes at high intensity, or combined, at a weekly basis....

Background It is critical for stroke survivors in working age to develop skills and confidence for long-term self-management of physical activity and exercise training to maintain a healthy lifestyle and decrease the risk of recurrent stroke and other cardiovascular diseases. Still, knowledge is scarce about concerns and experiences of physical act...

Background The joint associations of total and intensity-specific physical activity with obesity in relation to all-cause mortality risk are unclear. Methods We included 34 492 adults (72% women, median age 62.1 years, 2034 deaths during follow-up) in a harmonised meta-analysis of eight population-based prospective cohort studies with mean follow-...

The beneficial health effects of physical activity, in particular moderate-to-vigorous physical activity (MVPA), are well documented, but there is an ongoing scientific debate whether the domain matters, i.e., whether leisure time physical activity is beneficial and occupational physical activity is detrimental to health, referred to as the physica...

Introduction Efficient and effective evidence-based practice (EBP) strategies for managing fall prevention in primary health care are of great importance. To ensure that EBP methods have the potential to be implemented and maintained in clinical practice, patient perspective must be ensured. Novel programs need to be perceived as meaningful and fea...

Background Subjective and social wellbeing, avoiding sedentary behavior (SB) and engaging in physical activity (PA) are important factors for health in older adults, but the extent to which they are related to each other remains unclear. We aimed to investigate these correlations, and whether they differ by age. Methods A cross-sectional study was...

Background The StayBalanced programme has shown positive effects on fall prevention, balance control and fear of falling. Despite convincing evidence on the efficacy and effectiveness of balance training, there is a gap between research findings and what is provided in community-based and clinical health care settings. Therefore, transferring evide...

Background: Our aim was to describe and explore older adults' device-measured sedentary behavior and physical activity (PA) pattern by sex, age, education, marital status, body mass index, and physical function; and to assess agreement regarding fulfillment of PA recommendations, i.e. 150 min/week of moderate-to-vigorous intensity PA (MVPA), betwe...

Objectives To examine the joint associations of accelerometer-measured physical activity and sedentary time with all-cause mortality. Methods We conducted a harmonised meta-analysis including nine prospective cohort studies from four countries. 44 370 men and women were followed for 4.0 to 14.5 years during which 3451 participants died (7.8% morta...

By exploring multiple characteristics of physical activity and sedentary behaviour (SB), different physical activity profiles could be obtained, which may be beneficial for health and targeted physical activity interventions. The aim of this study was to identify distinct physical activity profiles based on accelerometer‐derived activity characteri...

Technology developments and demand for flexibility in health care and in contact with the health care system are two factors leading to increased use of eHealth solutions. The use of eHealth has been shown to have positive effects in people with chronic obstructive pulmonary disease, but the full potential for this group needs to be explored. There...

Objectives: The beneficial effects of a physically active lifestyle in aging are well documented. Understanding the factors of importance for physical activity in older adults are therefore essential. Informed by animal and human data linking the dopamine system to motivation and reward processes, we investigated the associations between variation...

The association between the composition of movement behaviours and mortality risk, acknowledging the composition nature of daily time data, is limited explored. The aim was to investigate how the composition of time spent in sedentary behaviours (SB), light intensity physical activity (LIPA) and moderate‐to‐vigorous physical activity (MVPA) is asso...

Background: Associations of objectively assessed physical activity in different intensities and risk of developing chronic disease that requires hospital care have not yet been examined in long term population-based studies. Studies addressing the link between physical activity and sedentary time and subsequent hospital admissions are lacking. Ob...

The development in research concerning sedentary behaviour has been rapid over the past two decades. This has led to the development of evidence and views that have become more advanced, diverse and, possibly, contentious. These include the effects of standing, the breaking up of prolonged sitting and the role of moderate-to-vigorous physical activ...

Objective To examine the dose-response associations between accelerometer assessed total physical activity, different intensities of physical activity, and sedentary time and all cause mortality. Design Systematic review and harmonised meta-analysis. Data sources PubMed, PsycINFO, Embase, Web of Science, Sport Discus from inception to 31 July 201...

Purpose: To evaluate the effects of the Stay Balanced program when this is transferred into a clinical setting regarding balance, gait speed, leg muscle strength, concerns about falling, and physical activity. Method: Implementation pilot study with a pre-post intervention design. Fifteen older adults, 75–91 years of age, participated in a progress...

Background Sedentary behavior is associated with health risks in adults. The potential benefits of reducing sedentary time may be dependent not only on decrease per se, but also on the type of activity it replaces. Few longitudinal studies have investigated the effects on mortality when replacing objectively assessed sedentary time with another phy...

Objectives: To investigate the associations of objectively assessed sedentary time, light intensity physical activity (PA), moderate to vigorous intensity PA (MVPA), and total PA with all-cause mortality and mortality from cardiovascular disease (CVD) or cancer in a Swedish population-based cohort with 15 years follow-up time. Design: Longitudin...

Physical activity (PA) is essential for older adults with osteoporosis, and health care professionals play important roles in promoting PA and encouraging patients to make healthy choices. However, many factors influence habitual PA and we have only limited knowledge about the perceptions and experiences of PA among older women with osteoporosis. T...

To describe objectively measured physical activity levels and patterns among community-dwelling older adults with osteoporosis, impaired balance, and fear of falling, and to explore the associations with gait, balance performance, falls self-efficacy, and health-related quality of life (HRQoL). Ninety-four individuals (75.6 ±5.4 years) were include...

Background and purpose: We have developed a 12-week balance training program for older adults shown to improve fall-related concerns, gait speed, balance performance, and physical function. We hypothesized that this balance training would also contribute to higher habitual physical activity (PA) levels and improved health-related quality of life (...

Objective: To give the rationale and evidence for and a detailed description of a rehabilitation programme of proven effectiveness in improving balance in older adults. Background theory and evidence: Based on the knowledge that balance loss usually occurs in situations when attention is divided, especially when being older, and that balance con...

To compare self-reported pedometer steps with accelerometer steps under free-living conditions in individuals with Parkinson's disease (PD) or osteoporosis (OP). Seventy-three individuals with PD and 71 individuals with OP wore a pedometer (Yamax LS2000) and an accelerometer (Actigraph GT1M/GT3X+) simultaneously for one week. Fifty-one individuals...
