Primary care is a promising venue to build patient motivation and confidence to increase physical activity ( PA ) . Physician PA counselling has demonstrated some success ; however , maintenance of behaviour change appears to require more intensive interventions . In reality , most physicians do not have the necessary training nor the time for this type of counselling . The purpose of this paper is to outline the rationale , methods , and interventions for the ongoing physical activity counselling ( PAC ) r and omized controlled trial ( RCT ) , which aims to assess the impact of integrating a PA counsellor into a primary care practice . This RCT has 2 arms : ( i ) brief PA counselling ( 2 - 4 min ) from a health care provider and ( ii ) brief PA counselling+intensive PA counselling from a PA counsellor ( 3 months ) . The impact of this intervention is being evaluated using the comprehensive RE- AIM framework . One hundred twenty insufficiently active adult patients , aged 18 to 69 y and recruited during regular primary care visits have been r and omized . Dependent measures include psychological mediators , PA participation , quality of life , and physical and metabolic outcomes . The PAC project represents an innovative , theoretically-based approach to promoting PA in primary care , focusing on psychological mediators of change . We anticipate that key lessons from this study will be useful for shaping future public health interventions , theories , and research OBJECTIVE To evaluate three strategies for promoting physical activity ( PA ) in a primary care setting . METHOD Data were collected between 2002 and 2004 from 136 patients attending two general practice s in Brisbane , Australia . Inactive patients ( 50 - 70 years ) were r and omly allocated to one of three hierarchical intervention groups : the general practitioner ( GP ) group received ' brief ' advice ; the GP+ES group also received behavior change advice from an exercise scientist ( ES ) ; and the GP+ES+P group also received a pedometer .  Self-reported PA and its determinants were measured at baseline and weeks 12 and 24 . Cardio-respiratory variables were measured at baseline and week 12 . RESULTS Overall , mean PA time increased by 84 and 128 min/week at weeks 12 and 24 ( p<.01 ) with no significant group differences . Small improvements in blood pressure and post-exercise heart rate were observed . At week 24 , the GP+ES+P group were more likely to report meeting PA guidelines than the GP group ( OR=2.39 95 % CI : 1.01 , 5.64 ) . CONCLUSION PA levels can be increased in mid- to older-age adults , either by brief advice from motivated GPs alone , or from collaboration between GPs and ESs . The most intense intervention ( GP+ES+P ) showed the most promising results OBJECTIVE To evaluate the effects of a comprehensive physical activity ( PA ) promotion programme in elementary schools on children 's total PA levels , leisure-time PA , physical fitness and psychosocial correlates of PA . DESIGN A pre-test-post-test design over two school years . SETTING AND SUBJECTS Sixteen elementary schools ( 764 children , mean age : 11.2 + /- 0.7 years ) were r and omly assigned to the intervention condition ( n = 8) and the control condition ( n = 8) . The intervention included a health-related physical education programme , an extracurricular PA promotion programme and classroom-based PA education lessons . In the total sample , leisure-time PA , psychosocial correlates of PA and physical fitness were measured using a PA question naire and the Eurofit test battery . In a sub- sample , total PA levels were measured using an accelerometer . RESULTS According to accelerometer data , children 's moderate PA and moderate-to-vigorous PA ( MVPA ) levels decreased less in the intervention schools than in the control schools ( P < 0.01 ) . The average time spent on MVPA decreased by 9 min per day in the intervention schools compared with 33 min per day in the control schools . Children in the intervention schools reported significantly more moderate PA in leisure time than the controls ( P < 0.05 ) . No overall improvement of physical fitness and no effects on the psychosocial correlates of PA were found . CONCLUSIONS The comprehensive PA promotion programme was successful in preventing a decline in children 's  total activity levels . Furthermore , the intervention increased children 's PA engagement in leisure time . Therefore , implementation needs to be encouraged Background Older adults are the least active population group . Interventions in residential setting s may support a multi-level approach to behavior change . Methods In a cluster r and omized control trial , 11 San Diego retirement communities were assigned to a physical activity ( PA ) intervention or a healthy aging attention control condition .  Participants were 307 adults over 65 years old . The multilevel PA intervention was delivered with the assistance of peer leaders , who were trained older adult from the retirement communities . Intervention components included individual counseling & self-monitoring with pedometers , group education sessions , group walks , community advocacy and pedestrian community change projects . Intervention condition by time interactions were tested using generalized mixed effects regressions . The primary outcomes was accelerometer measured physical activity . Secondary outcomes were blood pressure and objective ly measured physical functioning . Results Over 70 % of the sample were 80 years or older .  PA  significantly increased in the intervention condition ( 56 min of moderate-vigorous PA per week ; 119 min of light PA ) compared with the control condition and remained significantly higher across the 12 month study . Men and participants under 84 years old benefited most from the intervention . There was a significant decrease in systolic ( p < .007 ) and diastolic ( p < .02 ) blood pressure at 6 months . Physical functioning improved but the changes were not statistically significant . Conclusions Intervention fidelity was high demonstrating feasibility . Changes in PA and blood pressure achieved were comparable to other studies with much younger participants . Men , in particular , avoided a year-long decline in PA.Trial registration clincialtrials.gov Identifier : NCT01155011 INTRODUCTION Increased physical activity ( PA ) is a crucial factor in the prevention of physical deterioration , and resistance training ( RT ) is also a common and effective intervention for older adults . However , the effects of PA as an adjunct to RT on frailty status remains unclear ; therefore , we clarified the effect of a PA intervention with feedback , as an adjunct to resistance strength training , on the physical and mental outcomes of frail older adults . MATERIAL S AND METHODS We employed a r and omized controlled trial . Community-dwelling frail older adults in Japan were recruited to participate . Forty-one participants ( mean age 81.5 ) were r and omly assigned to engage in a resistance training with PA ( RPA group ) or RT group for six months . Frailty status and frailty scores , which were measured according to the Cardiovascular Health Study criteria -muscle strength , mobility , instrumental activities of daily living , and health-related quality of life-were assessed . RESULTS Participants in the RPA group exhibited a significant increase in light-intensity PA , the number of steps taken daily ( p < 0.05 ) , and lower-limb muscle strength ( p < 0.05 ) and a significant decrease in frailty scores . However , pre- and postintervention frailty status , instrumental activities of daily living , and health-related quality of life did not differ significantly . CONCLUSIONS Implementation of a PA intervention as an adjunct to RT is feasible , as it reduced frailty scores and increased lower-limb muscle strength and mobility in older adults with frailty symptoms Background Lack of physical activity ( PA ) is a known risk factor for many health conditions . The workplace is a setting often used to promote activity and health . We investigated the effectiveness of an intervention on  PA and productivity-related outcomes in an occupational setting . Methods We conducted a r and omized controlled trial of 12 months duration with two 1:1 allocated parallel groups of insurance company employees . Eligibility criteria included permanent employment and absence of any condition that risked the participant ’s health during PA . Subjects in the intervention group monitored their daily PA with an accelerometer , set goals , had access to an online service to help them track their activity levels , and received counseling via telephone or web messages for 12 months . The control group received the results of a fitness test and an information leaflet on PA at the beginning of the study . The intervention ’s aim was to increase PA , improve work productivity , and decrease sickness absence . Primary outcomes were PA ( measured as MET minutes per week ) , work productivity ( quantity and quality of work ; QQ index ) , and sickness absence ( SA ) days at 12 months . Participants were assigned to groups using block r and omization with a computer-generated scheme . The study was not blinded . Results There were 544 r and omized participants , of which 521 were included in the analysis ( 64 % female , mean age 43 years ) . At 12 months , there was no significant difference in physical activity levels between the intervention group ( n = 264 ) and the control group ( n = 257 ) . The adjusted mean difference was −206 MET min/week [ 95 % Bayesian credible interval −540 to 128 ; negative values favor control group ] . There was also no significant difference in the QQ index ( −0.5 [ −4.4 to 3.3 ] ) or SA days ( 0.0 [ −1.2 to 0.9 ] ) . Of secondary outcomes , body weight ( 0.5 kg [ 0.0 to 1.0 ] ) and percentage of body fat ( 0.6 % [ 0.2 % to 1.1 % ] ) were slightly higher in the intervention group . An exploratory subgroup analysis revealed no subgroups in which the intervention affected physical activity . No adverse events were reported . Conclusions The intervention was not found effective , and this study does not provide support for the effectiveness of the workplace PA intervention used here . Trial registration Clinical Trials.gov identifier : Background :  Physical activity ( PA )  is important for management of diabetes , yet practical interventions that achieve sustained behavior change are rare . Purpose : The goals of this research were to evaluate the effectiveness of a multifaceted PA intervention for people with type 2 diabetes that emphasized participant choice in activity selection . Baseline activity patterns were examined to determine whether they predicted changes in PA at 2 months . Methods : Three hundred thirty-five participants were recruited from 42 primary care physicians and then r and omized to either a computer-assisted , tailored self-management intervention ( N = 174 ) or health risk appraisal with feedback control ( N = 161 ) . Primary outcome measures included the Community Healthy Activities Model Program for Seniors Question naire , diet , and psychosocial assessment s at baseline and 2 months . Results : For 301 participants who completed the 2-month follow-up , the intervention significantly improved all PA ( p < .01 ) and moderate PA ( metabolic equivalents > 3.0 , p < .01 ) relative to controls . Baseline cluster analyses grouped participant activity patterns into three categories . At 2 months , cluster assignment differentially predicted change in calories expended in moderate , rote , sport , and lifestyle PA . Conclusions : A computer-assisted , multifaceted approach to PA demonstrated improvement after 2 months . The results suggest that individuals are capable of adjusting their activity patterns to maximize their PA With more social support and environment-centered interventions being recommended in web-based interventions , this study examined the efficacy of three intervention conditions aim ed at promoting physical activity ( PA ) in older adults . The efficacy analyses included the self-reported PA level , stage of change for PA and awareness about PA among participants . Eligible participants ( N = 149 ; M = 65 years old , SD = 6 ) , recruited in a unique Belgian French-speaking municipality , were r and omized in four research arms for a 3-month intervention : ( i ) web-based ; ( ii ) center-based ; ( iii ) mixed ( combination of web- and center-based ) ; and ( iv ) control ( no intervention ) . Web-based condition included a PA website and monthly tailored emails whereas center-based condition comprised 12 sessions ( 1 per week ) of group exercising . With a significant increase in PA , the PA stage of change and the PA awareness at 12 months , the mixed intervention condition seemed to include the key social and motivating elements for sustainable behavior change . Center-based intervention was more likely to produce significant improvements of the PA level and the stage of change for PA change whereas web-based intervention was more likely to extend the awareness about PA Background Many Australian children are insufficiently active to accrue health benefits and physical activity ( PA ) levels are consistently lower among youth of low socio-economic position .  PA levels decline dramatically during adolescence and evidence suggests that competency in a range of fundamental movement skills ( FMS ) may serve as a protective factor against this trend . Methods / design The Supporting Children ’s Outcomes Using Rewards Exercise and Skills ( SCORES ) intervention is a multi-component PA and FMS intervention for primary schools in low-income communities , which will be evaluated using a group r and omized controlled trial . The socio-ecological model provided a framework for the 12-month intervention , which includes the following components : teacher professional learning , student leadership workshops ( including leadership accreditation and rewards , e.g. , stickers , water bottles ) , PA policy review , PA equipment packs , parental engagement via newsletters , FMS homework and a parent evening , and community partnerships with local sporting organizations . Outcomes will be assessed at baseline , 6- and 12-months . The primary outcomes are PA ( accelerometers ) , FMS ( Test of Gross Motor Development II ) and cardiorespiratory fitness ( multi-stage fitness test ) . Secondary outcomes include body mass index [ using weight (kg)/height ( m2 ) ] , perceived competence , physical self-esteem , and resilience . Individual and environmental mediators of behavior change ( e.g. social support and enjoyment ) will also be assessed . The System for Observing Fitness Instruction Time will be used to assess the impact of the intervention on PA within physical education lessons . Statistical analyses will follow intention-to-treat principles and hypothesized mediators of PA behavior change will be explored . Discussion SCORES is an innovative primary school-based PA and FMS intervention design ed to support students attending schools in low-income communities to be more skilled and active . The findings from the study may be used to guide teacher pre-service education , professional learning and school policy in primary schools . Trial registration Australian New Zeal and Clinical Trials Registry No : Evidence supports the effectiveness of interventions delivered in primary care to promote physical activity ( PA ) . Specifically , approaches where physician counseling is coupled with other strategies ( eg , referrals to community re sources ) have been recognized as the most promising . The purpose of this study was to compare the effectiveness of a PA prescription plus referral intervention versus a prescription only intervention delivered in primary care . Ten family physicians and their female patients ( N = 35 , mean age = 36 years ) were r and omly assigned to 1 of 3 conditions : prescription plus  ( n = 12 ) ,  prescription only ( n = 12 ) , and  usual care ( n = 11 ) . The prescription plus group received a PA prescription plus a referral to a community program , the prescription only group received only the PA prescription , and the usual care group received usual health care .  The Godin Leisure-Time Exercise Question naire was used to measure PA . A significant increase on the PA score ( P < .05 , partial η2 = .178 ) and on total weekly PA minutes ( P < .05 , partial η2 = .179 ) was observed in both prescription groups after the intervention . There were no significant group differences ( P > .05 ) . No PA changes were observed in the usual care group . Findings from this pilot study suggest that brief PA counseling and a prescription delivered in primary care can be effective for promoting PA among women . Referring patients did not seem to enhance the effect on PA BACKGROUND : Physical activity ( PA ) reduces the rate of mobility disability , compared with health education ( HE ) , in at risk older adults . It is important to underst and aspects of performance contributing to this benefit . OBJECTIVE : To evaluate intervention effects on tertiary physical performance outcomes . DESIGN : The Lifestyle Interventions and Independence for Elders ( LIFE ) was a multi‐centered , single‐blind r and omized trial of older adults . SETTING : Eight field centers throughout the United States . PARTICIPANTS : 1635 adults aged 78.9 ± 5.2 years , 67.2 % women at risk for mobility disability ( Short Physical Performance Battery [ SPPB ] < 10 ) . INTERVENTIONS : Moderate PA including walking , resistance and balance training compared with HE consisting of topics relevant to older adults . OUTCOMES : Grip strength , SPPB score and its components ( balance , 4 m gait speed , and chair‐st and s ) , as well as 400 m walking speed . RESULTS : Total SPPB score was higher in PA versus HE across all follow‐up times ( overall P = .04 ) as was the chair‐st and component ( overall P < .001 ) . No intervention effects were observed for balance ( overall P = .12 ) , 4 m gait speed ( overall P = .78 ) , or grip strength ( overall P = .62 ) . However , 400 m walking speed was faster in PA versus HE group ( overall P = < .001 ) . In separate models , 29 % of the rate reduction of major mobility disability in the PA versus HE group was explained by change in SPPB score , while 39 % was explained by change in the chair st and component . CONCLUSION : Lower extremity performance ( SPPB ) was significantly higher in the PA compared with HE group . Changes in chair‐st and score explained a considerable portion of the effect of PA on the reduction of major mobility disability‐consistent with the idea that preserving muscle strength/power may be important for the prevention of major mobility disability OBJECTIVE Physical activity ( PA ) has been shown to provide health benefits for breast cancer patients . The effects of augmenting oncology healthcare provider ( HCP ) advice for PA with 3 months of telephone counseling versus contact control were evaluated in a r and omized trial . Our goal in this secondary analysis was to examine the amount of PA ( min/week ) needed for psychosocial benefits among both groups . METHODS After receiving brief HCP advice to become physically active , 192 women ( age in years : mean = 60.0 , SD = 9.9 ) who had completed treatment for Stage 0-IV breast cancer were r and omized to  telephone counseling to support PA ( n = 106 ) or contact control ( n = 86 ) . Their PA , fatigue , physical functioning , and quality of life were assessed at baseline ( before receiving HCP advice ) , 3 , 6 , and 12 months . A non-r and omized design was used to examine the dose-response relationship between PA and psychosocial outcomes . RESULTS Exercising for at least 150 min/week at moderate intensity was associated with improved physical functioning ( b = 5.9 , SE = 2.9 , p = 0.04 ) and quality of life ( b = 3.6 , SE = 1.9 , p = 0.05 ) at 3 months . These relationships were not found at 6 and 12 months ( p 's > 0.05 ) . However , women who reported at least 150 min/week of PA at both 3 and 6 months had significantly reduced fatigue ( b = 1.3 , SE = 0.7 , p = 0.05 ) and improved physical functioning ( b = 3.1 , SE = 1.3 , p = 0.02 ) and quality of life ( b = 2.0 , SE = 0.9 , p = 0.02 ) compared with women who did not meet this criterion . CONCLUSION Women who exercised at recommended levels ( at least 150 min/week ) and sustained this level of activity for at least 6 months accrued psychosocial benefits The Lifestyle Interventions and Independence for Elders ( LIFE ) Study is a Phase III r and omized controlled clinical trial ( Clinical trials.gov identifier : NCT01072500 ) that will provide definitive evidence regarding the effect of physical activity ( PA ) on major  mobility disability in older adults ( 70–89 years old ) who have compromised physical function . This paper describes the methods employed in the delivery of the LIFE Study PA intervention , providing insight into how we promoted adherence and monitored the fidelity of treatment . Data are presented on participants ’ motives and self-perceptions at the onset of the trial along with accelerometry data on patterns of PA during exercise training . Prior to the onset of training , 31.4 % of participants noted slight conflict with being able to meet the dem and s of the program and 6.4 % indicated that the degree of conflict would be moderate . Accelerometry data collected during PA training revealed that the average intensity – 1,555 counts/minute for men and 1,237 counts/minute for women – was well below the cutoff point used to classify exercise as being of moderate intensity or higher for adults . Also , a sizable subgroup required one or more rest stops . These data illustrate that it is not feasible to have a single exercise prescription for older adults with compromised function . Moreover , the concept of what constitutes “ moderate ” exercise or an appropriate volume of work is dictated by the physical capacities of each individual and the level of comfort/stability in actually executing a specific prescription OBJECTIVES To determine whether elderly people who meet national guidelines have higher physical function ( PF ) scores than those who do not and the effect on functional trajectory when physical activity ( PA ) levels change from above to below this threshold , or vice versa . DESIGN Pooled data . SETTING Two 6-month r and omized controlled trials aim ed at increasing PA in adults . PARTICIPANTS Adults aged 65 to 94 ( N=357 ) . INTERVENTION PA counseling over the telephone and through mailed material s. MEASUREMENTS  Self-reported PA  dichotomized at 150 minutes/week and PF using the Medical Outcomes Study 36-item Short Form Question naire PF subscale . RESULTS At baseline , individuals reporting 150 minutes or more of moderate PA/week had mean PF scores that were 20.3 points higher than those who did not ( P<.001 ) . Change in PA minutes from above threshold to below threshold or from below threshold to above threshold from baseline to 6 months result ed in an average change in PF of -11.18 ( P<.001 ) and + 5.10 ( P=.05 ) , respectively . CONCLUSION These findings suggest that PA is an important predictor of functional status . Older sedentary adults can improve PF by meeting recommended PA levels . Conversely , dropping below recommended PA levels has a deleterious effect on PF . Given the importance of PF in maintenance of independence and quality of life in older adults , adherence to recommended PA guidelines should be endorsed Background Engaging in regular physical activity ( PA ) is critical for health , and adopting a consistent PA routine early in life is associated with greater PA over the lifespan . College women with weight concerns are at risk for weight gain , which may be prevented with regular PA . However , little is known about changes in PA engagement in this at-risk group . Purpose Using an outcome expectancy framework , this study used a prospect i ve longitudinal design to examine changes in PA during the first 2 years of college . We tested for concurrent and prospect i ve within-person relations between body satisfaction/perceived eating behavior and  PA  to determine when weight-concerned college women may increase or decrease PA . Methods Women who reported weight concerns at the start of college ( n = 294 ) completed five assessment s over 2 years , including measured weight , body/eating experiences , and 4 days of pedometer steps ( per assessment ) . Multilevel models addressed the result ing nested data structure ( days within assessment s within participants ) . Results Over 2 years , within-person change accounted for 65 % of PA variability ( ICC = 0.35 ) . PA  was greatest at ( and subsequent to ) times when body satisfaction was lower , and when disinhibited eating and hedonic hunger were higher , than an individual ’s average ( ps < 0.05 ) . These changes were associated with 1–3 % of the recommended daily step totals . Conclusions Weight-conscious college women  show greater PA after negative eating and weight experiences . As these experiences change over time , health promotion efforts should help college women identify alternative , positive motivators for PA , which could facilitate consistent PA engagement Objectives To describe the risk factors associated with injuries result ing from physical education ( PE ) , leisure time physical activity ( leisure time PA ) and sports in 9–12-year-old children . Design Prospect i ve cohort study . Setting Primary schools . Participants Nine hundred and ninety-five children aged 9–12 years . Main outcome measures Injuries occurring during either PE class  , leisure time PA or sports , and caused the child to at least stop the current activity were recorded prospect ively . Individual weekly exposure was estimated from baseline and follow-up question naires . Potential risk factors were gender , age , socioeconomic status , ethnicity , habitual level of PA , body mass index and a motor fitness . A multivariate Cox proportional hazard regression model was developed , accounting for clustering within schools . Results Gender , age and level of PA were independent significant risk factors for injury . Different modalities of PA had different injury risk factors . Most importantly , the low levels of habitual PA  significantly increased injury risk . Conclusions The children at highest injury risk are the target audience of the contemporary PA promotion efforts . PA promotion should also focus on injury prevention 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
Over 1.5 years of using EVS in a large hospital system , improvements occurred in relative weight loss among overweight patients and reduction in glycosylated hemoglobin among diabetic patients .
Few studies have examined a brief physical activity tool as a vital sign measure .
Initial investigations suggest the promise of these simple and quick assessment tools , and research is needed to test the effects of their use on chronic disease outcomes
INTRODUCTION Physical activity ( PA ) is strongly endorsed for managing chronic conditions , and a vital sign tool ( indicator of general physical condition ) could alert providers of inadequate PA to prompt counseling or referral .
This systematic review examined the use , definitions , psychometric properties , and outcomes of brief PA instruments as vital sign measures , with attention primarily to studies focused on arthritis .
