Feasibility of the Remote Physical Activity Follow-Up Intervention after the Face-to-Face Program for Healthy Middle-Aged Adults: A Randomized Trial Using ICT and Mobile Technology.

Although the effectiveness of face-to-face and remote intervention for increasing and maintaining physical activity (PA) have been compared, the effect of combining the two forms of intervention is unknown. The purpose of this study was to examine the feasibility of the remote PA follow-up intervention after the face-to-face PA program on changing PA behaviors and some health outcomes in healthy middle-aged adults. As a secondary analysis, we also attempted a preliminary analysis of the difference in the number of behavior change interviews in the remote PA follow-up intervention. After the face-to-face intervention, 30 healthy subjects were randomly divided into four behavior change coaching interviews (BCI4 group) or three BCI (BCI3 group). The results of this study showed that body weight, body fat mass, and waist circumference were significantly reduced after face-to-face intervention, and were further reduced after remote PA follow-up intervention. However, the difference in the number of BCI affected only body fat mass. The remote PA follow-up intervention may have potential to maintain the effects of face-to-face intervention. In the future, it is necessary to refine the research design and conduct a full-scale intervention study.

Protocol: A cluster randomized controlled trial of a mobile application to support physical activity maintenance after an exercise oncology program

Objectives/purposeIncreasing physical activity (PA) among adults living with cancer is a public health priority, especially for those in remote/rural locations who have worse health outcomes and lower PA than urban populations. Mobile health technology may overcome barriers to PA participation and change PA behavior. However, few mobile health interventions have focused on sustaining PA long-term in remote/rural adults living with cancer. The present study will examine the effectiveness of a mobile health application to promote PA maintenance in remote/rural adults after completing an exercise oncology program. MethodsThe 24-week prospective 2-arm pilot randomized controlled trial will be embedded within an exercise oncology program in in remote/rural Canada. Participants will be randomized by class cluster 1:1 to the intervention or EXCEL only control group. Both groups will participate in a supervised 12-week group-based exercise oncology program, followed by a 12-week PA maintenance period. The intervention group will use a mobile health application, Zamplo, to complete regular health check-ins and reflections via graphs for 24 weeks. Data will be collected at baseline, 4, 12, 24 weeks using surveys, activity tracking, and semi-structured interviews. Analyses will assess intervention effectiveness to promote PA maintenance and examine participant perspectives and use of Zamplo to support PA. SignificanceThe present study will generate new knowledge on the potential of an mHealth app to promote PA maintenance in remote/rural adults living with cancer. It will inform the integration of mobile health resources within online-delivered exercise oncology programs, leading to sustainable long-term health benefits for this population.

Testing a physical education-delivered autonomy supportive intervention to promote leisure-time physical activity in lower secondary school students: the PETALS trial

BackgroundInadequate physical activity in young people is associated with several physical and mental health concerns. Physical education (PE) is a potentially viable existing network for promoting physical activity in this population. However, little research has been conducted on whether PE teachers can influence students’ engagement in leisure-time physical activity. The present study therefore examined the efficacy of an intervention aimed at increasing PE teachers’ autonomy support on students’ leisure-time physical activity (the PETALS trial). The intervention was guided by the trans-contextual model (TCM) explaining the processes by which PE teachers’ provision of autonomy support during PE promotes students’ motivation and engagement in physical activity in their leisure time.MethodsThe study adopted a cluster-randomized, waitlist control intervention design with randomization by school. Participants were PE teachers (N = 29, 44.83%female; M age = 42.83, SD = 9.53 yrs) and their lower secondary school students (N = 502, 43.82%female; M age = 14.52, SD = 0.71 yrs). We measured TCM constructs, including perceived autonomy support, autonomous motivation in PE and leisure time, beliefs and intentions towards leisure-time physical activity, and physical activity behavior at baseline, post-intervention, and at one-, three-, and six-months. Study hypotheses were tested through a series of ANOVAs and structural equation models using post-intervention and one-month follow-up data.ResultsWe found no changes in TCM constructs or physical activity behavior in either group at post-intervention or at 1 month. Path analyses supported two propositions of the TCM as change variables: perceived autonomy support had a significant effect on autonomous motivation in PE and autonomous motivation in PE had a significant effect on autonomous motivation in leisure time. Although we found a direct effect of autonomous motivation in leisure time on physical activity, we did not find support for the third premise of the TCM that autonomous motivation in leisure time indirectly affects physical activity through beliefs and intentions.ConclusionsCurrent findings did not support the efficacy of the PETALS intervention at changing physical activity behavior and TCM constructs. More research is required to determine whether the TCM predictive validity is supported when other model variables are manipulated through experimental and intervention studies.Trial registrationISRCTN, ISRCTN39374060.

Abstract A17: An innovative physical activity intervention in overweight and obese adults using continuous glucose monitor

Abstract Introduction: Regular physical activity (PA) lowers the risk of endometrial, breast, and colorectal cancer. However, nearly half of American adults are not sufficiently active. The physical inactivity rate is even higher among the overweight and obese population, which, in combination with the unfavorable effect of excess body weight, puts this population at a greater risk for cancer. Advancements in wearable sensor technology provide opportunities for personalized approaches to increase motivation to be active. The current pilot study used continuous glucose monitors (CGM) to demonstrate the immediate, physiologic benefits of PA. Methods: Insufficiently active (<150 mins of moderate intensity PA per week) overweight and obese (body mass index >= 25 kg/m2) adults (18-65 years old) without diabetes are being recruited to participate in this pilot intervention. Upon enrollment, participants go through a one-on-one PA education session that includes a discussion about the health benefits of recommended PA levels, demonstration of the acute effect of PA on daily glucose patterns using a web-based glucose simulator, calculation of personal heart rate zones for moderate intensity PA, and development of an exercise plan. After the education session, participants are given a Fitbit Alta HR wristband and are instructed to wear it over the next 10 days. Participants are also given a Freestyle Libre CGM, which consists of a sensor and a reader. The sensor is inserted into the back of the upper arm to collect interstitial glucose data every 15 minutes for 10 days after activation. The reader displays current glucose readings and a graph of the 8 previous hours of glucose data upon scanning the sensor. Participants are instructed to scan the sensor at least 4 times a day and are encouraged to achieve at least 150 minutes of moderate-intensity PA each week. At the end of the self-monitoring period, participants return their Fitbit and have their CGM sensor removed. Results: Thus far, 10 of 20 participants have enrolled in and completed the study. These participants have been 100% female, 70% obese, and 20% Hispanic with a mean age of 41.5 (SD = 8.6) years old. On average, participants scanned their sensor 6 times each day and wore the Fitbit for all 10 days. On average, participants highly rated each component of the education session (on a 5-point scale) for improving their PA knowledge (mean = 4.4), increasing their PA motivation (mean = 4.4), and providing personally relevant information (mean = 4.6). Participants also reported a very positive experience wearing the CGM, with mean ratings (on a 5-point scale) of 4.8 for usability, 4.6 for convenience, 4.9 for value, 4.9 for relevance, and 4.7 for motivating. Conclusion: These preliminary data suggest that using a CGM to motivate PA among nondiabetic adults is feasible and acceptable. Future research will be conducted to examine the effect a CGM-based PA intervention has on changing PA behavior. Citation Format: Yue Liao, Christopher J. Miller, Diana L. Urbauer, Therese B.

Changing the Physical Activity Behavior of Adults With Fitness Trackers: A Systematic Review and Meta-Analysis.

To examine whether a fitness tracker (FT) intervention changes physical activity (PA) behavior compared to a control condition or compared to an alternative intervention. Searches between January 01, 2010, and January 01, 2019, were conducted in PubMed, CINAHL, Cochrane CENTRAL, EMBASE, and PsycINFO. Randomized clinical trials of adults using an FT to change PA behavior were included. Nonclinical trials, studies that included the delivery of structured exercise, and/or studies that only used the FT to assess PA were excluded. Extracted features included characteristics of the study population, intervention components, PA outcomes, and results. Papers were pooled in a statistical meta-analysis using a fixed effects model. Where statistical pooling was not possible, standardized mean difference (SMD) and 95% confidence intervals (CI) were calculated. Findings were presented in a narrative form and tables. Of 2076 articles found, 21 were included in the review. A small yet significant positive effect (SMD = 0.25, 95% CI = 0.17-0.32; P < .01; I2 = 56.9%; P = .03) was found in step count for interventions compared to control. A small yet significant negative effect (SMD = -0.11, 95% CI = -0.20 to -0.02; P = .02; I2 = 58.2%; P = 0.03) was found in moderate-to-vigorous PA for interventions compared to an alternative intervention. Trackers may enhance PA interventions, as a general positive effect is found in step count compared to a control. However, there is no evidence of a positive effect when interventions are compared to an alternative intervention. It is unknown whether results are due to other intervention components and/or clinical heterogeneity.

Effectiveness of a Behavior Change Technique-Based Smartphone Game to Improve Intrinsic Motivation and Physical Activity Adherence in Patients With Type 2 Diabetes: Randomized Controlled Trial.

BackgroundRegular physical activity (PA) is an essential component of a successful type 2 diabetes treatment. However, despite the manifest evidence for the numerous health benefits of regular PA, most patients with type 2 diabetes remain inactive, often due to low motivation and lack of PA enjoyment. A recent and promising approach to help overcome these PA barriers and motivate inactive individuals to change their PA behavior is PA-promoting smartphone games. While short-term results of these games are encouraging, the long-term success in effectively changing PA behavior has to date not been confirmed. It is possible that an insufficient incorporation of motivational elements or flaws in gameplay and storyline in these games affect the long-term motivation to play and thereby prevent sustained changes in PA behavior. We aimed to address these design challenges by developing a PA-promoting smartphone game that incorporates established behavior change techniques and specifically targets inactive type 2 diabetes patients.ObjectiveTo investigate if a self-developed, behavior change technique-based smartphone game designed by an interdisciplinary team is able to motivate inactive individuals with type 2 diabetes for regular use and thereby increase their intrinsic PA motivation.MethodsThirty-six inactive, overweight type 2 diabetes patients (45-70 years of age) were randomly assigned to either the intervention group or the control group (one-time lifestyle counseling). Participants were instructed to play the smartphone game or to implement the recommendations from the lifestyle counseling autonomously during the 24-week intervention period. Intrinsic PA motivation was assessed with an abridged 12-item version of the Intrinsic Motivation Inventory (IMI) before and after the intervention. In addition, adherence to the game-proposed PA recommendations during the intervention period was assessed in the intervention group via the phone-recorded game usage data.ResultsIntrinsic PA motivation (IMI total score) increased significantly in the intervention group (+6.4 (SD 4.2; P<.001) points) while it decreased by 1.9 (SD 16.5; P=.623) points in the control group. The adjusted difference between both groups was 8.1 (95% CI 0.9, 15.4; P=.029) points. The subscales “interest/enjoyment” (+2.0 (SD 1.9) points, P<.001) and “perceived competence” (+2.4 (SD 2.4) points, P<.001) likewise increased significantly in the intervention group while they did not change significantly in the control group. The usage data revealed that participants in the intervention group used the game for an average of 131.1 (SD 48.7) minutes of in-game walking and for an average of 15.3 (SD 24.6) minutes of strength training per week. We found a significant positive association between total in-game training (min) and change in IMI total score (beta=0.0028; 95% CI 0.0007-0.0049; P=.01).ConclusionsIn inactive individuals with type 2 diabetes, a novel smartphone game incorporating established motivational elements and personalized PA recommendations elicits significant increases in intrinsic PA motivation that are accompanied by de-facto improvements in PA adherence over 24 weeks.Trial RegistrationClinicalTrials.gov NCT02657018; https://clinicaltrials.gov/ct2/show/NCT02657018

Correlating the Physical Activity Patterns of People with Moderate to Severe Multiple Sclerosis Disability and Their Family Caregivers.

Purpose: People with multiple sclerosis (PwMS) and their family caregivers often react to the impact of the disease as an interdependent dyad. The aim of this exploratory study was to examine interdependence in the physical activity (PA) patterns of dyads affected by moderate to severe MS disability. Method: A total of 15 pairs of PwMS and their family caregivers wore accelerometers for 7 days. By collecting data simultaneously from both partners, we tested interdependence using the dyad as the unit of analysis. Results: PwMS and caregivers averaged 4,091.3 (SD 2,726.3) and 6,160.2 (SD 1,653.0) steps per day, respectively. The mean number of minutes per day of sedentary, light, and moderate to vigorous activity for PwMS was 566.3 (SD 97.7), 167.4 (SD 94.0), and 7.6 (SD 12.4), respectively, and 551.9 (SD 92.4), 199.6 (SD 63.4), and 21.4 (SD 18.2), respectively, for caregivers. Interdependence between dyads for sedentary, light, moderate to vigorous activity, and step count was low and non-significant (rs=0.20, 0.26, 0.13, and -0.27, respectively; p>0.05). Conclusions: Although our findings do not support the interdependence of PA between caregivers and care recipients with MS, they do show that both partners are not engaging in sufficient PA to achieve important health benefits. These findings are important because they indicate that the dyads are likely to benefit from interventions for changing PA behavior.

Improvement of physical activity in chronic obstructive pulmonary disease by pulmonary rehabilitation and pharmacological treatment.

Physical activity (PA) is defined as bodily movement produced by skeletal muscles with energy expenditure beyond resting levels. PA is closely related to reduced morbidity and mortality in chronic obstructive pulmonary disease (COPD). Self-report questionnaires are often subject to recall bias, correlating poorly with objectively qualified PA, and do not provide an accurate estimate of free-living energy expenditure. PA may be objectively evaluated by newly developed tri-axial accelerometers by quantifying steps or body movements over a period of time. Low-intensity, home-based pulmonary rehabilitation (PR) using pedometer feedback improves PA. Improvement in physiological factors correlates with increased walking time in stable elderly COPD patients. This review focuses on the effects of PR and pharmacological treatment on PA in COPD patients. We selected 32 studies from our literature search evaluating the effects of PR and 11 studies examining the effects of pharmacological treatment on PA. Findings in both categories were inconsistent. Nineteen studies showed a positive effect with PR whereas 13 showed no effect. Eight studies showed a positive effect, while three revealed no effect from pharmacological intervention. As both interventions increase exercise capacity without a consistent effect on PA, counseling with behavioral changes may be necessary to achieve a significant and lasting increase in PA. Changing PA behavior in COPD patients requires an interdisciplinary approach involving specialists in respiratory medicine, rehabilitation, social, and behavioral sciences. Future research in this area is warranted to advance our knowledge in this area, specifically with regard to the interaction of pharmacological and non-pharmacological interventions.

A scoping review of studies exploring physical activity among adolescents and young adults diagnosed with cancer.

Physical activity can improve health, functional capacity, and quality of life among children and adults diagnosed with cancer. Physical activity may also offer important benefits to adolescents and young adults diagnosed with cancer (AYAs). We conducted a scoping review to: determine the extent, range, and nature of published studies on physical activity among AYAs; identify knowledge gaps; and provide directions for future research. We searched 4 electronic databases for published studies. Two authors independently scanned the titles, abstracts, and full-texts against inclusion criteria: original research with humans, published in an English-language peer-reviewed journal, ≥50% of participants were diagnosed with cancer between the ages of 15 and 39years, and included at least 1 measure of physical activity behavior. Data were extracted from studies meeting these criteria and subsequently summarized narratively. Our search yielded 4729 articles; 32 met inclusion criteria. These included 18 cross-sectional and 4 longitudinal studies that explored descriptive (ie, sociodemographic or medical), physical, personal/psychological, social, other health behaviors, and/or other factors as antecedents or correlates of physical activity. The remaining 10 were intervention studies that focused on changing physical activity behavior or on testing the effects of physical activity. We can conclude that physical activity is not well researched among AYAs. More high-quality research adopting longitudinal or intervention study designs that incorporate a range of descriptive, physical, personal/psychological, social, and environmental measures are warranted to better inform the development of behavior change interventions as well as to establish the benefits of physical activity for AYAs.

Activity matters: a web-based resource to enable people with multiple sclerosis to become more active

Increasing physical activity (PA) through exercise is associated with improvements in many of the symptoms associated with multiple sclerosis (MS) such as fatigue, strength, balance, and mobility. Despite this, people with MS remain largely inactive. Interventions that are grounded in theory and that aim to change PA behavior need to be developed. The purpose of this study was to describe the development process of a web-based resource, namely, "Activity Matters," to enable people with MS to become more active. Development of the "Activity Matters" online intervention was guided by the UK's Medical Research Council (MRC) framework for the development and evaluation of complex interventions and the behavior change wheel (BCW). Seven sources of data were used to inform the process and were mapped on to both the MRC and BCW frameworks. The intervention is theoretically based, and constructs including knowledge, memory, attention and decision processes, skills, social influences, environmental context and resources, beliefs about capabilities, beliefs about consequences, goals, and emotions were recognized as important. "Activity Matters" is the first MS PA intervention to be developed using the theoretical approach outlined by the BCW and MRC complex interventions frameworks. The next phase of this work is to test the usability, acceptability, and preliminary effectiveness of "Activity Matters" among people with MS.

Do multiple sclerosis symptoms moderate the relationship between self-efficacy and physical activity in people with multiple sclerosis?

To investigate the bivariate correlations between objective physical activity (PA), self-efficacy, and a range of multiple sclerosis (MS) symptom measures. Also, to determine whether any MS symptom measures moderate the relationship between self-efficacy and PA. Baseline analysis from a randomized control trial exercise plus a behavior change intervention was used. Fifty-nine physically inactive people with a definite diagnosis of MS were included. Participants were asked to record 7-day objective PA with the SenseWear Armband. Additionally, measures of self-efficacy (Exercise Self-Efficacy Scale), walking endurance (6-min walk test), impact of walking (12-Item MS Walking Scale [MSWS-12]), anxiety and depression (Hospital Anxiety and Depression Scale [HADS]) and fatigue (Modified Fatigue Impact Scale) were assessed before intervention. Pearson's correlations and moderation analysis were conducted. Self-efficacy was positively associated with PA (r = .30, p < .05). HADS-Depression (r = -.25, p < .05) and MSWS-12 (r = -.31, p < .01) demonstrated statistically significant negative correlations with self-efficacy but not with PA. Moderation analysis illustrated a significant interaction between anxiety and self-efficacy (r = .39, p < .03) with an R2 value of .15. The interaction was significant at lower values of anxiety, suggesting that the relationship between self-efficacy and PA is stronger when levels of anxiety are lower. This article confirms the potential role of MS symptoms, in particular anxiety, in explaining PA behavior in an inactive sample of persons with multiple sclerosis (pwMS). Further exploration is warranted, and future PA interventions should acknowledge the potential interplay of psychosocial constructs such as self-efficacy and anxiety in changing PA behavior among pwMS.

Physical Activity Interventions Among Older Adults: A Literature Review

Physical activity (PA) is important in the management of chronic illness among older adults worldwide. Researchers have conducted several intervention studies to increase PA behavior in this population. This review of the past 12 years of relevant PA intervention research among adults aged 60 years and older systematically summarized research findings, identified characteristics of successful interventions, and proposed areas of future research. There were 20 studies reviewed for this article, most employing a combination of cognitive-behavioral intervention design. Cognitive-based only and combination interventions were more successful in changing PA behavior; however, behavioral-based interventions demonstrated more long-term changes in PA behavior. Among theory-based interventions, self-efficacy was the most commonly operationalized construct. Findings from this review may inform future primary research to promote PA behavior among older adults, as well as gerontological clinical practice.

Ambulante Sporttherapie für Patientinnen mit Essstörungen: Ein Pilotprojekt

Many patients with Anorexia and Bulimia Nervosa (AN, BN) engage in sport and physical activity in an excessive and compulsive manner, mostly to influence weight and shape. Many of them experience guilt in case of not exercising. However, sport and physical exercise can also have a positive effect on mental illness by influencing mood, sense of self-esteem and body experience. Until now, only few programs for eating disorder patients exist which aim at changing physical activity behavior and use sport and exercise activities in a therapeutic way. We developed a sport-therapeutic program designed for outpatients with eating disorders. It supervises sport and physical exercise and helps patients to use sport and exercise in a healthy manner. This report presents the program's manual and first experiences based on half-standardized interviews.

Health Promotion in Older Chinese

Aging, in conjunction with decreasing physical activity, is associated with a range of health problems. Simple, low-maintenance, population-based means of promoting activity to counteract the age-associated decline are required. We therefore assessed the effect of pedometry and buddy support to increase physical activity. We undertook a clustered randomized trial (HKCTR-346) of 24 community centers involving 399 older Chinese participants (≥ 60 yr). Centers were randomly allocated to 1) pedometry and buddy, 2) pedometry and no buddy, 3) no pedometry and buddy, and 4) no pedometry and no buddy with a 2 × 2 factorial design. The trial simultaneously tested the individual and combined effects of the interventions. The intervention groups also received monthly organized group activities to provide encouragement and support. Outcome measures were assessed at 6 and 12 months, including physical fitness and activity and cardiovascular disease risk factors (anthropometry and blood pressure). From the 24 centers, 356 volunteers (89.2%) completed the study. Those receiving the interventions had higher mean physical activity levels at 12 months of 1820 (95% confidence interval (CI) = 1360-2290) and 1260 (95% CI = 780-1740) MET·min·wk(-1), respectively relative to the decrease in the control groups. The buddy peer support intervention significantly improved mean aerobic fitness (12% [95% CI = 4%-21%]) and reduced both body fat (-0.6% [95% CI = -1.1% to 0.0%]) and time to complete the 2.5-m get-up-and-go test (-0.27 [95% CI = -0.53 to -0.01] s). No other improvements in the cardiovascular disease risk factors were observed. The combination of motivational tools was no better than the individual interventions. Both motivational interventions increased physical activity levels, and the buddy style improved fitness. These tools could be useful adjuncts in the prevention of obesity and age-related complications.

Exercise and the Liver: Implications for Therapy in Fatty Liver Disorders

The increasing recognition that fatty liver plays a direct role in the pathogenesis of cardiovascular and metabolic disease has resulted in significant research enquiry into the efficacy of lifestyle therapy in modulating liver fat. Recently, this has extended to the specific investigation of a possible independent benefit of physical activity/exercise in nonalcoholic fatty liver disease (NAFLD). In this article we review the effect of acute and regular exercise (training) on metabolism, including liver glucose and lipid metabolism, and the available human trials that have compared the benefit of regular exercise versus a nonexercise control on liver fat. The limited human research suggests that exercise can reduce liver fat and that this benefit may be mediated, in part, by a reduction in hepatic lipogenesis. The relative importance of extrahepatic adaptations and acute versus regular exercise in explaining this benefit are discussed. From a clinical perspective, the revelation of a benefit of exercise per se offers a novel approach for liver fat reduction, and highlights the importance of incorporating fitness assessment and prescription in the management of patients with fatty liver disorders. Implementation of exercise therapy in a clinical setting is arguably the biggest challenge because evidence shows that mere provision of information about the benefits of exercise and/or exercise prescription to the patient does not translate to positive outcomes. Rather, the focus should be on implementing strategies to promote behavior change including regular contact and assessment with a health care professional, self-monitoring, and personalization of goals that focus on changing physical activity behavior.

A Continuous Glucose Monitoring and Problem-Solving Intervention to Change Physical Activity Behavior in Women with Type 2 Diabetes: A Pilot Study

Diabetes technology has the potential to provide useful data for theory-based behavioral counseling. The aims of this study are to evaluate the feasibility, acceptability, and preliminary efficacy of a continuous glucose monitoring and problem-solving counseling intervention to change physical activity (PA) behavior in women with type 2 diabetes. Women (n=29) with type 2 diabetes were randomly assigned to one of two treatment conditions: continuous glucose counseling and problem-solving skills or continuous glucose monitoring counseling and general diabetes education. Feasibility data were obtained on intervention dose, implementation, and satisfaction. Preliminary efficacy data were collected at baseline and 12 weeks on the following measures: PA amount and intensity, diet, problem-solving skills, self-efficacy for PA, depression, hemogoloin A1c, weight, and blood pressure. Demographic and implementation variables were described using frequency distributions and summary statistics. Satisfaction data were analyzed using Wilcoxon rank. Differences between groups were analyzed using linear mixed-modeling. Women were mostly white/non-Latina with a mean age of 53 years, a 6.5-year history of diabetes, and suboptimal glycemic control. Continuous glucose monitoring plus problem-solving group participants had significantly greater problem-solving skills and had greater, although not statistically significant, dietary adherence, moderate activity minutes, weight loss, and higher intervention satisfaction pre- to post-intervention than did participants in the continuous glucose monitoring plus education group. A continuous glucose monitoring plus problem-solving intervention was feasible and acceptable, and participants had greater problem-solving skills than continuous glucose monitoring plus education group participants.

Physical Activity Intervention for Osteoporosis Prevention in Black Older Adults

BackgroundPhysical activity (PA) is one of the lifestyle behaviors considered important in osteoporosis prevention. This study examined the effect of the Revised Health Belief Model theory‐based education program on osteoporosis prevention. The PA component is reported here.Research methodA repeated measure, randomized, wait‐list control design with 6‐weekly education sessions was offered to 130 consented black older adults in community settings in South Florida. The two groups were evaluated on the effect of the program on changes in calcium intake and PA after the program. PA benefits/barriers were discussed and demonstrated along with nutrition topics. PA was measured using Physical Activity, Osteoporosis Self‐Efficacy and other questionnaires based on the constructs of the theory.ResultsA total of 110 (experimental 59, wait‐list 51) completed all assessments. Mean age was 70.15±10.44 yrs and 90.0% were female. Reported PA scores were not significantly different (p&gt;.05, η2 =.02), however osteoporosis self‐efficacy scores indicated participants perceived they could change their behaviors to impact their health (p&lt;.05, η2=.20).ConclusionThough a combined dietary and PA program was effective with an Asian group, this population has more resistance to change PA behavior. Further studies are needed to explore alternative strategies to improve PA in this minority group.Grant Funding Source: N/A
