Introduction Large proportions of the population are not meeting recommended levels of physical activity and have increasingly sedentary lifestyles . Low levels of physical activity are predictive of poor health outcomes and time spent sedentary is related to a host of risk factors independently of physical activity levels . Building an evidence base of the best approaches to intervene in the lifestyles of inactive individuals is crucial in preventing long-term disease , disability and higher mortality rates . Methods and analysis Systematic search es will be conducted on all relevant data bases ( eg , PubMed , Scopus , CINAHL , PsycINFO ) . Studies will be included if they assess interventions aim ed at changing physical activity or sedentary behaviour levels in adults ( over 18 ) who are inactive and do not suffer from chronic conditions . Studies must also be r and omised controlled trials ( RCTs ) , have a primary outcome of physical activity or sedentary behaviour , and measure outcomes at least 6 months after intervention completion . Studies will be coded using the Behaviour Change Technique ( BCT ) taxonomy v1 and Template for Intervention Description and Replication ( TIDieR ) guidelines . 2 review ers will independently screen full-text articles and extract data on study characteristics , participants , BCTs , intervention features and outcome measures . Study quality will also be assessed independently by 2 review ers using the Cochrane risk of bias tool . A meta- analysis will be considered if there is sufficient homogeneity across outcomes . GRADE criteria will be used to assess quality of evidence . Dissemination This will be the first review to systematic ally appraise interventions aim ed at changing the physical activity or sedentary behaviour of inactive individuals using RCT design s with a 6-month follow-up post-intervention . This review will better inform intervention design ers targeting inactive population s and inform the design of a future complex intervention . Review registration number This protocol was registered with the International Prospect i ve Register of Systematic Review s ( PROSPERO ) on 17 October 2014 ( registration number : CRD42014014321 ) Objective . To evaluate the relationship of physical activity ( PA ) and sedentary behaviour with  gestational weight gain ( GWG ) and birth weight . Design . Combined data from two prospect i ve studies : ( 1 ) nulliparous pregnant women without BMI restrictions and ( 2 ) overweight and obese pregnant women at risk for gestational diabetes . Methods . Daily PA and sedentary behaviour were measured with an accelerometer around 15 and at 32–35 weeks of gestation . The association between time spent in moderate-to-vigorous PA ( MVPA ) and in  sedentary activities  with GWG and birth weight was determined . Main outcome measures were GWG between 15 and 32 weeks of gestation , average GWG per week , and birth weight . Results . We studied 111 women . Early in pregnancy , 32 % of women spent ≥30 minutes/day in at least moderate PA versus 12 % in late pregnancy . No significant associations were found between time spent in MVPA or sedentary behaviour with GWG or birth weight . Conclusions . We found no relation  between MVPA and sedentary behaviour with GWG or birth weight . The small percentage of women meeting the recommended levels of PA indicates the need to inform and support pregnant women to maintain regular PA , as there seems to be no adverse effect on birth weight and maintaining PA increases overall health ABSTRACT Lack of  physical activity  (  PA  ) and high levels of sedentary behaviour ( SB ) have been associated with health problems . This systematic review evaluates the effectiveness of school-based interventions to increase PA  and decrease SB  among 15–19-year-old adolescents , and examines whether intervention characteristics ( intervention length , delivery mode and intervention provider ) and intervention content ( i.e. behaviour change techniques , BCTs ) are related to intervention effectiveness . A systematic search of r and omised or cluster r and omised controlled trials with outcome measures of PA and /or SB rendered 10 results . Risk of bias was assessed using the Cochrane risk of bias tool . Intervention content was coded using Behaviour Change Technique Taxonomy v1 . Seven out of 10 studies reported significant increases in PA . Effects were generally small and short-term ( Cohen 's d ranged from 0.132 to 0.659 ) . Two out of four studies that measured SB reported significant reductions in SB . Interventions that increased PA  included a higher number of BCTs , specific BCTs ( e.g. , goal setting , action planning and self-monitoring ) , and were delivered by research staff . Intervention length and mode of delivery were unrelated to effectiveness . More studies are needed that evaluate long-term intervention effectiveness and target SBs among older adolescents Purpose : Young adults who have been treated for cancer face several health and psychosocial risks . To minimize these risks , is it imperative that they address any modifiable risk factors , such as sedentary lifestyle . Unfortunately , more than half of young adult cancer survivors remain sedentary . To facilitate the adoption of physical activity ( PA ) in this population -potentially reducing health and psychosocial risks-we developed and pilot tested an internet-based PA intervention for young survivors . Patients and methods : Eighteen young adults , aged 18 to 39 , who had been diagnosed with cancer in the past 10 years were recruited . Participants were r and omized to receive access to the PA website for 12 weeks or information about other cancer-related websites . Intervention feasibility and acceptability was assessed only among those in the PA website group ; PA and psychosocial outcomes ( mood , fatigue ) were assessed in both groups . Results : Findings revealed that 86 % of participants in the PA website group would recommend the intervention to others and most ( 71 % ) were " satisfied " or " very satisfied " with it . Further , 100 % rated getting onto the website as " very easy " and 86 % rated the information on the site as " very easy " to underst and . The logging feature , followed by the goal - setting feature , were most often accessed by participants . Participants also rated the graphing and stage-matched manual features as helpful . Estimates of effect sizes for between-group differences at 12 weeks were medium for PA outcomes and large for psychosocial outcomes . Conclusions : This internet-based PA intervention targeting young adult cancer survivors is feasible and acceptable and may benefit this population BACKGROUND Underst and ing the inter-relationships between lifestyle factors in youth is important with respect to the development of effective promotional programmes for healthy eating and active living . The present study aim ed to explore the associations of dietary habits ( DH ) with physical activity ( PA ) and screen time ( ST )  among Saudi adolescents aged between 15 and 19 years of age relative to gender . METHODS Data were obtained from the Arab Teens Lifestyle Study , a school-based multicentre lifestyle study conducted in 2009/2010 in three major cities in Saudi Arabia . A multistage stratified cluster r and om sampling technique was used . The number of participants with complete data for  DH  and  PA  was 2886 and the respective number for DH and ST was 2822 . Assessment included weight , height , body mass index , total daily ST ( television viewing , video/computer games and Internet use ) , PA and DH using self-reported question naires . RESULTS Females were significantly more sedentary and less active than males ( P < 0.001 ) . Two-way analysis of covariance , controlling for age , showed significant ( P < 0.05 ) gender by PA and gender by ST interactions for several DH . Logistic regression analyses revealed significant associations of higher PA with a higher consumption of fruit , vegetables , milk , French fries/potato chips and energy drinks , whereas higher ST was significantly associated with a higher consumption of sugar-sweetened drinks , fast foods , cake/doughnuts and energy drinks . CONCLUSIONS Healthful dietary habits were associated mostly with  PA  , whereas sedentary behaviours , independent of PA , negatively impacted upon eating behaviours . The low PA levels and high sedentary levels of Saudi females represent a great concern . The results reported in the present study have important implication s for both youth public health policies and intervention programmes OBJECTIVES ICAPS ( Intervention Centred on Adolescents ' Physical activity and Sedentary behaviour ) is aim ed at preventing excessive weight gain and cardiovascular risk in adolescents by promoting physical activity ( PA ) with an emphasis on recreational and daily-life PA , with a lifelong perspective . DESIGN R and omized study design ed to last for four years . Study cohort constituted of 954 first-level students ( 91 % of eligible pupils ) , aged 11.7 + /- 0.6 y ( mean + /- SD ) from four pairs of schools r and omly selected in eastern France , after sociogeographical stratification . In each pair , intervention status was r and omised at school-level . The program , not limited to school setting s , involves multiple partners with three objectives : 1 ) changing attitudes through debates and access to attractive activities during breaks and after-school hours , 2 ) encouraging social support , 3 ) providing environmental conditions that enable PA . Adapted times and places , open participation , emphasis on fun , meeting with others and absence of competitive aspects are used to reduce usual barriers to PA .  Accessibility and safety are permanent concerns . RESULTS Prevalence of overweight was 23.7 % . High participation rates were attained ( 50 % participated in at least one weekly activity ) . At six-month , the proportion of intervention adolescents  not performing supervised PA out of academic PA  was reduced by half ( 36 % to 17 % vs 42 % to 42 % in controls P < 10 - 4 ) ; the proportion of those spending > 3 h/day in sedentary occupations decreased ( 34 % to 28 % vs 27 % to 36 % ; P < 10 - 4 ) . CONCLUSION These data demonstrate the feasibility of implementing a multilevel PA intervention program in adolescents . Six-month results document increased PA  and decreased sedentary behaviour Background To our knowledge , no studies have aim ed at improving the PA level in south Asian immigrant men residing in Western countries , and few studies have considered the relevance of SCT constructs to the PA behaviour of this group in the long term . The observed low  physical activity ( PA ) level among south Asian immigrants in Western countries may partly explain the high prevalence of cardiovascular diseases ( CVD ) and type 2 diabetes ( T2D ) in this group . We have shown previously in a r and omised controlled trial , the Physical Activity and Minority Health study ( PAMH ) that a social cognitive based intervention can beneficially influence PA level and subsequently reduce waist circumference and insulin resistance in the short-term . In an extended follow-up of the PAMH study : we aim ed 1 ) to determine if the intervention produced long-term positive effects on PA level six months after intervention ( follow-up 2 ( FU2 ) ) , and 2 ) to identify the social cognitive mediators of any intervention effects . Methods Physically inactive Pakistani immigrant men ( n = 150 ) who were free of CVD and T2D were r and omly assigned to a five months PA intervention or a control group . Six months after the intervention ended , we telephoned all those who attended FU1 and invited them for a second follow-up test ( FU2 ) ( n = 133 ) . PA was measured using ActiGraph accelerometers . Statistical differences between groups were determined by use of ANCOVA . Results Significant differences ( baseline to FU2 ) between the groups were found for all PA variables ( e.g. , total PA level , sedentary time , PA intensity ) . Support from family and outcome expectancies increased more in the intervention group compared with the control group . Self-efficacy did not differ significantly between groups . Conclusions Our results show that a multi component PA programme can increase PA over the short and long term in a group of immigrant Pakistani men . However , we could not identify the factors that mediated these changes in PA . Protocol ID07112001326 , NCT ID : Background Identifying ways to promote physical activity and decrease sedentary time during childhood is a key public health issue . Research on the putative influences on preschool children ’s  physical activity ( PA ) and  sedentary behavior  ( SB ) is limited and has yielded inconsistent results . Our aim was to identify correlates of PA and SB in preschool children . Methods Cross-sectional data were drawn from the Swiss Preschoolers ’ Health Study ( SPLASHY ) , a Swiss population -based cohort study . Of 476 two to six year old children , 394 ( 54 % boys ) had valid PA data assessed by accelerometry .  Information on exposure data was directly measured or extracted from parental question naires . Multilevel linear regression modeling was used to separately assess associations between 35 potential correlates and  total PA ( TPA ) , moderate-to-vigorous PA ( MVPA ) and SB . Results In total , 12 correlates from different domains were identified . TPA and MVPA were greater in boys than girls , increased with age and were positively associated with gross motor skills . Children from single parent families had a higher level of TPA and spent less time sedentary than those living with two parents . Time spent outdoors was positively associated with TPA and negatively with SB . The child ’s activity temperament was related all three outcomes , whereas parental sports club membership , living area per person and neighborhood safety were associated with SB only . Fixed and r and om factors in the final models accounted for 28 % , 32 % and 22 % of the total variance in TPA , MVPA and SB , respectively . Variance decomposition revealed that age , sex and activity temperament were the most influential correlates of both , TPA and MVPA , whereas the child ’s activity temperament , time outdoors and neighborhood safety were identified as the most important correlates of SB . Conclusions A multidimensional set of correlates of young children ’s  activity behavior has been identified . Personal factors had the greatest influence on PA , whereas environmental-level factors had the greatest influence on SB . Moreover , we identified a number of previously unreported , potentially modifiable correlates of young children ’s PA and SB . These factors could serve to define target groups or become valuable targets for change in future interventions .Trial registration Current Controlled Trials IS RCT N41045021 ( date of registration : 21.03.14 ) BakckgroundThe first aim was to examine the effect of the UP4FUN pilot intervention on children ’s total sedentary time . The second aim was to investigate if the intervention had an effect on  children ’s physical activity ( PA ) level . Finally , we aim ed to investigate demographic differences ( i.e. age , gender , ethnicity , living status and having siblings ) between children in the intervention group who improved in sedentary time and PA at post-test and children in the intervention group who worsened in sedentary time and PA at post-test . Methods The six weeks UP4FUN intervention was tested in a r and omized controlled trial with pre-test post-test design with five intervention and five control schools in Belgium and included children of the 5th and 6th grade . The children wore accelerometers for seven days at pre- and post-test . Analyses included children with valid accelerometer data for at least two weekdays with minimum 10h-wearing time and one weekend day with 8h-wearing time . Result Final analyses included 372 children ( 60 % girls , mean age = 10.9 ± 0.7 years ) . There were no significant differences in the change in sedentary time or light PA between intervention and control schools for the total sample or for the subgroup analyses by gender . However , children ( specifically girls ) in the intervention group had a higher decrease in moderate-to-vigorous PA than children in the control group . In the intervention group , children who lived with both parents and children with one or more siblings were less likely to reduce sedentary time after exposure to the intervention . Older children , girls and children who lived with both parents were less likely to increase light PA after the intervention . Conclusion The UP4FUN intervention did not result in an effect on children ’s sedentary time . Based on the high amounts of accelerometer-derived sedentary time in this age group , more efforts are needed to develop strategies to reduce children ’s sedentary time The aim of this study was to investigate the impact of a physical activity (PA)-focused behavioural intervention during and after  pulmonary rehabilitation ( PR ) on PA levels ( primary aim ) , health-related outcomes and self-efficacy ( secondary aims ) of patients with COPD . Thirty-two patients were r and omly assigned to an experimental group ( EG ) or control group ( CG ) . The EG received a PA-focused behavioural intervention during PR ( 3 months ) and follow-up support ( 3 months ) . The CG received PR ( 3 months ) . Daily PA was collected : number of steps ; time spent in moderate-to-vigorous PA ( MVPA ) , total PA and sedentary activities ( SA ) . Secondary outcomes comprised exercise capacity , muscle strength , health-related quality of life ( HRQOL ) and self-efficacy . Measures were collected at baseline , 3 and 6 months . Compared with the CG , the EG improved the number of steps ( p = 0.006 ) and time spent in MVPA ( p = 0.007 ) , total PA ( p = 0.014 ) and SA ( p = 0.018 ) at 3 months . Differences were maintained after follow-up support ( 0.025 ≤ p ≤ 0.040 ) , except for SA ( p = 0.781 ) . Exercise capacity , muscle strength and HRQOL were increased at 3 and 6 months ( p ≤ 0.002 ) with no between-group differences ( 0.148 ≤ p ≤ 0.987 ) . No changes were observed in self-efficacy ( p = 0.899 ) . A PA-focused behavioural intervention during and after PR may improve patients ' PA levels . Further research is warranted to assess the sustainability of the findings Background Walking interventions have been shown to have a positive impact on physical activity ( PA ) levels , health and wellbeing for adult and older adult population s. There has been very little work carried out to explore the effectiveness of walking interventions for adults with intellectual disabilities . This paper will provide details of the Walk Well intervention , design ed for adults with intellectual disabilities , and a r and omised controlled trial ( RCT ) to test its effectiveness . Methods / design This study will adopt a RCT design , with participants allocated to the walking intervention group or a waiting list control group . The intervention consists of three PA consultations ( baseline , six weeks and 12 weeks ) and an individualised 12 week walking programme . A range of measures will be completed by participants at baseline , post intervention ( three months from baseline ) and at follow up ( three months post intervention and six months from baseline ) . All outcome measures will be collected by a research er who will be blinded to the study groups . The primary outcome will be steps walked per day , measured using accelerometers . Secondary outcome measures will include time spent in PA per day ( across various intensity levels ) , time spent in sedentary behaviour per day , quality of life , self-efficacy and anthropometric measures to monitor weight change . Discussion Since there are currently no published RCTs of walking interventions for adults with intellectual disabilities , this RCT will examine if a walking intervention can successfully increase PA , health and wellbeing of adults with intellectual disabilities . Trial registration IS RCT N : IS RCT Background Physical activity ( PA ) is associated with positive cardio-metabolic health and emerging evidence suggests sedentary behavior ( SB ) may be detrimental to children 's health independent of PA . The primary aim of the Transform-Us ! study is to determine whether an 18-month , behavioral and environmental intervention in the school and family setting s results in higher levels of PA and lower rates of SB among 8 - 9 year old children compared with usual practice ( post-intervention and 12-months follow-up ) . The secondary aims are to determine the independent and combined effects of PA and SB on  children 's cardio-metabolic health risk factors ; identify the factors that mediate the success of the intervention ; and determine whether the intervention is cost-effective . Methods / design A four-arm cluster-r and omized controlled trial ( RCT ) with a 2 × 2 factorial design , with schools as the unit of r and omization . Twenty schools will be allocated to one of four intervention groups , sedentary behavior ( SB-I ) , physical activity ( PA-I ) , combined SB and PA ( SB+PA-I ) or current practice control ( C ) , which will be evaluated among approximately 600 children aged 8 - 9 years in school year 3 living in Melbourne , Australia . All children in year 3 at intervention schools in 2010 ( 8 - 9 years ) will receive the intervention over an 18-month period with a maintenance ' booster ' delivered in 2012 and children at all schools will be invited to participate in the evaluation assessment s. To maximize the sample and to capture new students arriving at intervention and control schools , recruitment will be on-going up to the post-intervention time point . Primary outcomes are time spent sitting and in PA assessed via accelerometers and inclinometers and survey . Discussion To our knowledge , Transform-Us ! is the first RCT to examine the effectiveness of intervention strategies for reducing children 's overall sedentary time , promoting PA and optimizing health outcomes . The integration of consistent strategies and messages to children from teachers and parents in both school and family setting s is a critical component of this study , and if shown to be effective , may have a significant impact on educational policies as well as on pedagogical and parenting practice s . Trial registration ACTRN12609000715279 ; Current Controlled Trials IS RCT The purpose of this study was to investigate the benefits of a pedometer and a cognitive-behavioural group intervention for promoting physical activity ( PA ) in type 2 diabetes patients . We recruited 41 participants and r and omized them into an intervention group ( IG ) ( n = 20 ) and a control group ( CG ) ( n = 21 ) . The intervention consisted of five sessions within 12 weeks , a booster session after 22 weeks and a pedometer . Primary outcome was PA assessed by accelerometer ( minutes per day ) and pedometer ( steps per day ) . Secondary outcomes were weight , body mass index , blood pressure , haemoglobin A1c and total cholesterol . After 12 weeks , the IG increased with more than 2000 steps day−1 compared with the CG , whereas sedentary behaviour decreased more than 1 hour day−1 in the IG and showed no change in the CG . There was no intervention effect on the accelerometer-based PA nor on health measurements . After 1 year , the increase in steps per day remained significant in the IG , but sedentary activity increased again to baseline levels . This pilot study showed that the combination of a 12-week cognitive-behavioura intervention and a pedometer has a significant short-term impact on daily steps and sedentary behaviour but that the effects on total PA and long-term effects were limited OBJECTIVE To investigate the association between physical activity ( PA ) and risk of mortality in a large middle-aged cohort stratified by inflammatory status . PATIENTS AND METHODS A total of 336,560 individuals ( mean age , 39.7 years ; 58 % male ) who underwent comprehensive health screenings were enrolled in this prospect i ve cohort study . They were grouped according to self-reported PA level using a question naire : no regular PA with a sedentary lifestyle , regular but insufficient PA ( below the guidelines ) , sufficient PA ( concordant with the guidelines ) , and health-enhancing PA . Inflammation was assessed via high-sensitivity C-reactive protein ( hsCRP ) level . Study end points were all-cause , cardiovascular-related , and cancer-related mortality . RESULTS During the 1,976,882 person-years of follow-up ( median follow-up duration , 6.17 years ) , 2062 deaths occurred . Compared with a sedentary lifestyle , the hazard ratios ( 95 % CIs ) on the multivariable Cox proportional hazards regression analyses for all-cause mortality by PA level were 0.95 ( 0.84 - 1.07 ) , 0.85 ( 0.72 - 0.99 ) , and 0.75 ( 0.60 - 0.93 ) ( P for trend=.003 ) , and those for cardiovascular- and cancer-related mortality were 0.95 , 0.80 , and 0.55 ( P for trend=.05 ) and 0.82 , 0.83 , and 0.78 ( P for trend=.01 ) , respectively . Compared with participants with low hsCRP levels and any regular PA , those with high hsCRP levels and no regular PA had a significantly higher risk of mortality ( 1.59 [ 1.38 - 1.84 ] ) . CONCLUSION Higher PA levels were associated with a dose-dependent reduced risk of cardiovascular-related , cancer-related , and all-cause mortality . Individuals with high hsCRP levels and no regular PA had the highest risk of mortality This pilot study examined the effects of a teacher-taught , locomotor skill (LMS)-based physical activity ( PA ) program on the LMS and PA levels of minority preschooler-aged children . Eight low-socioeconomic status preschool classrooms were r and omized into LMS-PA ( LMS-oriented lesson plans ) or control group ( supervised free playtime ) . Interventions were delivered for 30 min/day , five days/week for six months . Changes in PA ( accelerometer ) and LMS variables were assessed with MANCOVA .  LMS-PA group exhibited a significant reduction in during-preschool ( F ( 1,16 ) = 6.34 , p = .02 , d = 0.02 ) and total daily ( F ( 1,16 ) = 9.78 , p = .01 , d = 0.30 ) percent time spent in sedentary activity .  LMS-PA  group also exhibited significant improvement in leaping skills , F ( 1 , 51 ) = 7.18 , p = .01 , d = 0.80 ) . No other , significant changes were observed . The implementation of a teacher-taught , LMS-based PA program could potentially improve LMS and reduce sedentary time of minority preschoolers Background There are numerous published controlled trials assessing the safety and the benefits of physical activity ( PA ) for child and adult cancer survivors . However , trials exclusively comprised of adolescent cancer survivors aged 13 - 19 years , who may experience different health and quality of life ( QOL ) effects as a function of their developmental status , are lacking . Rather , some trials have included both adolescent and child cancer survivors together . Objective The aim of this systematic review was to synthesize the findings from r and omized controlled trails ( RCTs ) and controlled clinical trials ( CCTs ) investigating the effects of PA on health and QOL outcomes in sample s comprised of > 50 % adolescent cancer survivors to summarize the current state of evidence , identify knowledge gaps , and highlight areas in need of additional research within this population . Methods Using a search strategy developed for this review , 10 electronic data bases were search ed for RCTs and CCTs that reported on the effects of PA on at least 1 health and /or QOL outcome in sample s comprised of > 50 % adolescent cancer survivors . Results From the 2249 articles identified , 2 CCTs met the predetermined eligibility criteria and were included in this review . Combined , 28 adolescents ( of 41 participants ) who were receiving active treatment participated in the 2 studies review ed . A total of 4 health and QOL outcomes ( ie , bone mass , fatigue , grip strength , QOL ) were assessed pre- and post-PA intervention . Conclusions On the basis of the 2 studies review ed , PA appears to be safe and feasible .  PA also shows promise to mitigate reductions in bone mass and might be a viable strategy to improve fatigue , grip strength , and QOL . High- quality controlled trials with larger sample s exclusively comprised of adolescent cancer survivors that assess a wide range of outcomes are needed to determine the effects of PA on health and QOL outcomes in this population Objective . To assess the effectiveness of interventions that focus on reducing  sedentary behavior ( SB ) among school-age youth and to identify elements associated with interventions ' potential for translation into practice setting s. Methods . A comprehensive literature search was conducted using 4 data bases for peer- review ed studies published between 1980 and April 2011 . R and omized trials , which lasted at least 12 weeks , aim ed at decreasing  SB among children aged 6 to 19 years were identified . Results . Twelve studies were included ; 3 focused only on SB , 1 focused on  physical activity ( PA )  , 6 were combined SB and PA interventions , and 2 studies targeted SB , PA , and diet .  The majority of the studies were conducted in a school setting , while others were conducted in such setting s as clinics , community centers , and libraries . Conclusions . Overall , interventions that focused on decreasing SB were associated with reduction in time spent on SB and /or improvements in anthropometric measurements related to childhood obesity . Several of the studies did consider elements related to the intervention 's potential for translation into practice setting BACKGROUND Sedentary time ( ST ) is negatively associated with cardiometabolic health and fitness . Traditional cardiac rehabilitation ( CR ) programming may not significantly reduce ST . The objectives of the study were to assess the feasibility and practicality of activPAL devices for measuring ST in CR , and whether prompting cues to interrupt sedentary behaviour can decrease ST and improve clinical outcomes . METHODS An 8-week , two-arm pilot r and omized controlled trial allocated coronary artery disease patients to either a control ( usual care CR ) or intervention ( CR + sedentary prompts from an activPAL3-VT ) group . Primary outcomes included : recruitment ; acceptability ; completion ; and , adherence rates . Secondary outcomes included changes in : ST ; physical activity ( PA ) ; cardiometabolic health ; psychosocial health ; and , fitness . RESULTS Forty participants ( 16 females ; 19 intervention ; 62 ± 10 years ) were r and omized . Outcome data were available for 95 % of participants . All but one participant completed the full intervention . Most ( 73 % ) intervention participants felt the prompts had somewhat changed their sedentary behaviour . At baseline , participants spent 47 % of their day sedentary . No significant group differences in changes for any of the ST , PA or fitness outcomes were observed . The mean group difference for post-intervention ST ( controlling for baseline ) was 30.3 min/day ( 95 % CI : -51.7 , 112.2 ) in favour of the intervention . The intervention group reported significantly better physical health and had a lower ratio of total cholesterol-to-high density lipoprotein when compared to controls . CONCLUSIONS It is feasible to use activPAL devices to measure ST in a CR setting . Further studies are needed to assess the effectiveness of multi-component sedentary behaviour interventions
Face to face and telephone-based self-management programmes were identified as having promise to engage stroke survivors in PA behaviour change .
Background Increasing physical activity ( PA ) levels ( regular movement such as walking and activities of daily living ) and reducing time spent sedentary improves cardiovascular health and reduces morbidity and mortality .
Fewer than 30 % of independently mobile stroke survivors undertake recommended levels of PA .
Sedentary behaviour is also high in this population .
We aim ed to systematic ally review the study characteristics and the promise of interventions targeting free-living PA and /or sedentary behaviour in adult stroke survivors .
