Effectiveness, efficiency, duration, and costs of recruiting for an African American women's lifestyle physical activity program

Overcoming Pandemic-Related Challenges in Recruitment and Screening: Strategies and Representation of Older Women With Cardiovascular Disease for a Multidomain Lifestyle Trial to Prevent Cognitive Decline

BACKGROUND

Recruiting participants with cardiovascular disease into research during the COVID-19 pandemic was challenging, particularly those at risk of health disparities.

OBJECTIVE

During the pandemic, 12 cohorts of older women with cardiovascular disease were recruited from cardiology clinics into a lifestyle intervention trial to prevent cognitive decline. Objectives were to ( a ) describe the results of modified recruitment/screening strategies to overcome pandemic-related challenges and ( b ) evaluate differences in age, race, and ethnicity between patients recruited/randomized, recruited/not randomized (entered recruitment but not randomized because of being ineligible or not interested), and not recruited (clinic patients who met preliminary criteria but did not enter recruitment).

METHODS

This was a cross-sectional descriptive analysis. In-person study strategies proposed before the COVID-19 pandemic were modified before study onset (September 2020). Women 65 years or older with cardiovascular disease were recruited from cardiology clinics by clinicians, posted flyers, and letters mailed to patients randomly selected from electronic health record data extractions. Patients were classified as recruited/randomized, recruited/not randomized, and not recruited.

RESULTS

Of 5719 patients potentially eligible, 1689 patients entered recruitment via referral (49.1%), posted flyers (0.5%), or mailed letters (50.3%), and 253 patients were successfully recruited/randomized. Recruited/randomized participants were, on average, 72.4 years old (range, 65-90 years old), non-Hispanic White (54.2%), non-Hispanic Black (38.3%), Hispanic/Latinx (1.6%), and other/not reported (5.1%). The recruited/randomized group was significantly younger with fewer patients of Hispanic/Latinx ethnicity compared with those not recruited.

CONCLUSIONS

During the pandemic, all recruitment/screening goals were met using modified strategies. Differences in sociodemographic representation indicate a need for tailored strategies.

Recruitment and Retention Strategies for Underrepresented Populations and Adults With Arthritis in Behavioral Interventions: A Scoping Review

OBJECTIVE

To identify strategies used to recruit and retain underrepresented populations and populations with arthritis or fibromyalgia (FM) into behavioral programs targeting exercise, physical activity, or chronic disease self management.

METHODS

Five bibliographic databases were searched for articles published between January 2000 and May 2022. The search focused on strategies and best practices for recruiting and retaining underrepresented populations or populations with arthritis or FM into disease self-management or physical activity/exercise programs. Abstracts and full-text articles were screened for inclusion by 2 independent reviewers, and 2 reviewers extracted data from included articles.

RESULTS

Of the 2,800 articles, a total of 43 publications (31 interventions, 8 reviews, 4 qualitative/descriptive studies) met criteria and were included. The majority of studies focused on physical activity/exercise (n = 36) and targeted African American (n = 17), Hispanic (n = 9), or arthritis populations (n = 7). Recruitment strategies that were frequently used included having race- or community-matched team members, flyers and information sessions in areas frequented by the population, targeted emails/mailings, and word of mouth referrals. Retention strategies used included having race- or community-matched team members, incentives, being flexible, and facilitating attendance. Most studies used multiple recruitment and retention strategies.

CONCLUSION

This scoping review highlights the importance of a multifaceted recruitment and retention plan for underrepresented populations and populations with arthritis or FM in behavioral intervention programs targeting exercise, physical activity, or chronic disease self management. Additional research is needed to better understand the individual effects of different strategies and the costs associated with the various recruitment/retention methods in underrepresented populations and populations with arthritis.

DNP-PhD Collaboration in NINR-Funded Physical Activity Trials: A Series of Case Studies

Collaboration between Doctor of Nursing Practice (DNP) scholars and Doctor of Philosophy (PhD) scholars is crucial to efficiently advance and disseminate nursing science. Also, DNP-PhD collaboration can help achieve priorities outlined in the recent National Institute of Nursing Research (NINR) Strategic Plan. The purpose of this series of case studies is to describe exemplars of ongoing DNP-PhD collaborations across three NINR-funded trials (1 completed, 2 ongoing) testing physical activity interventions for women at risk for cardiovascular disease. In our three physical activity intervention trials for women, we categorized examples of DNP-PhD collaboration by the four phases of the team-based research model (development, conceptualization, implementation, and translation). Across all three trials, DNP and PhD scholars contributed successfully to all phases of research in an iterative manner. Future work should focus on expanding DNP-PhD collaboration in behavioral trials, which can inform adapted, contemporary models of iterative DNP-PhD collaboration.

Effects of the COVID‐19 pandemic on recruitment for the working women walking program

The global pandemic of coronavirus disease 2019 (COVID‐19) affected many aspects of randomized controlled trials, including recruiting and screening participants. The purpose of this paper is to (a) describe adjustments to recruitment and screening due to COVID‐19, (b) compare the proportional recruitment outcomes (not completed, ineligible, and eligible) at three screening stages (telephone, health assessment, and physical activity assessment) pre‐ and post‐COVID‐19 onset, and (c) compare baseline demographic characteristics pre‐ and post‐COVID‐19 onset in the Working Women Walking program. The design is a cross‐sectional descriptive analysis of recruitment and screening data from a 52‐week sequential multiple assignment randomized trial (SMART). Participants were women 18–70 years employed at a large urban medical center. Recruitment strategies shifted from in‐person and electronic to electronic only post‐COVID‐19 onset. In‐person eligibility screening for health and physical activity assessments continued post‐COVID‐19 onset with Centers for Disease Control and Prevention precautions. Of those who expressed interest in the study pre‐ and post‐COVID‐19 onset (n = 485 & n = 269 respectively), 40% (n = 194) met all eligibility criteria pre‐COVID‐19 onset, and 45.7% (n = 123) post‐COVID‐19 onset. Although there were differences in the proportions of participants who completed or were eligible for some of the screening stages, the final eligibility rates did not differ significantly pre‐COVID‐19 versus post‐COVID‐19 onset. Examination of differences in participant demographics between pre‐ and post‐COVID‐19 onset revealed a significant decrease in the percentage of Black women recruited into the study from pre‐ to post‐COVID‐19 onset. Studies recruiting participants into physical activity studies should explore the impact of historical factors on recruitment.

Recruiting African American parents of school-aged children in a physical activity study: Lessons learned

OBJECTIVES

To describe the recruitment strategies and lessons learned when enrolling African American parents/caregivers of school-aged children (ages 6-12 years) in an online survey of physical activity. With physical activity serving as a modifiable behavioral risk factor for several chronic diseases (obesity and cardiovascular diseases), little is understood regarding the influences on African Americans' physical activity participation to develop culturally appropriate physical activity interventions. Gaining a better understanding of physical activity influences is possible through research, yet recruiting and enrolling African Americans in health research is a challenge.

METHODS

Over a three-month period, a multidimensional approach (distribution of flyers, community partnerships, network sampling, African American researcher, effective communication, and data collection procedures) was used for study recruitment.

RESULTS

We exceeded our recruitment goal of 105 participants. A total of 127 African American parent/caregivers of school-aged children enrolled, which included both females/mothers (n = 87, 69%) and males/fathers (n = 40, 31%). Network sampling was the single most effective recruitment strategy for reaching this population. Lessons learned in this study includes considering participant burden and their comfort with technology, as well as gaining community trust.

DISCUSSION

Lessons learned in recruiting African American parents provides a guide for future research. Efforts are needed to further increase the representation of African American males in health research.

A study protocol for MindMoves: A lifestyle physical activity and cognitive training intervention to prevent cognitive impairment in older women with cardiovascular disease

INTRODUCTION

Cognitive impairment (CI) and cardiovascular disease (CVD) disproportionately affect women compared to men, and CVD increases risk of CI. Physical activity and cognitive training can improve cognition in older adults and may have additive or synergistic effects. However, no combined intervention has targeted women with CVD or utilized a sustainable lifestyle approach. The purpose of the trial is to evaluate efficacy of MindMoves, a 24-week multimodal physical activity and cognitive training intervention, on cognition and serum biomarkers in older women with CVD. Three serum biomarkers (brain-derived neurotrophic factor [BDNF], vascular endothelial growth factor [VEGF], and insulin-like growth factor 1 [IGF-1]) were selected as a priori hypothesized indicators of the effects of physical activity and/or cognitive training on cognition.

METHODS

The study design is a randomized controlled trial with a 2 × 2 factorial design, to determine independent and combined efficacies of Mind (tablet-based cognitive training) and Move (lifestyle physical activity with goal-setting and group meetings) on change in cognition (primary outcome) and serum biomarkers (secondary outcomes). We will recruit 254 women aged ≥65 years with CVD and without CI from cardiology clinics. Women will be randomized to one of four conditions: (1) Mind, (2) Move, (3) MindMoves, or (4) usual care. Data will be obtained from participants at baseline, 24, 48, and 72 weeks.

DISCUSSION

This study will test efficacy of a lifestyle-focused intervention to prevent or delay cognitive impairment in older women with CVD and may identify relevant serum biomarkers that could be used as early indicators of intervention response.

Study protocol for a sequential multiple assignment randomized trial (SMART) to improve physical activity in employed women

INTRODUCTION

Physical activity monitors, motivational text messages, personal calls, and group meetings, have proven to be efficacious physical activity interventions. However, individual participant response to these interventions varies drastically. A SMART design (sequential multiple assignment randomized trial) provides an effective way to test interventions that start with an initial treatment and then transition to an augmented treatment for non-responders. We describe a SMART to determine the most effective adaptive intervention to increase physical activity (steps, moderate-to-vigorous physical activity) and improve cardiovascular health among employed women who are not regularly physically active. The SMART uses combinations of four treatments: 1) enhanced physical activity monitor (Fitbit wearable activity monitor and mobile app with goal setting and physical activity prescription), 2) text messages, 3) personal calls, and 4) group meetings.

METHODS

Participants (N = 312) include women ages 18-70 employed at a large academic medical center. Women will be randomized to an initial intervention, either an enhanced physical activity monitor or enhanced physical activity monitor + text messaging. Non-responders to the initial intervention at 2 months will be randomized to either personal calls or groups meetings for the next 6 months. At 8 months, all participants will return to only an enhanced physical activity monitor until their final 12-month assessment.

DISCUSSION

Results of this study will add to the literature on improving physical activity in employed women. This study will identify effective interventions for women who respond to less intensive treatments, while maximizing benefits for those who need a more intensive approach.

A pedometer-based walking intervention in 45- to 75-year-olds, with and without practice nurse support: the PACE-UP three-arm cluster RCT

BACKGROUND

Guidelines recommend walking to increase moderate to vigorous physical activity (MVPA) for health benefits.

OBJECTIVES

To assess the effectiveness, cost-effectiveness and acceptability of a pedometer-based walking intervention in inactive adults, delivered postally or through dedicated practice nurse physical activity (PA) consultations.

DESIGN

Parallel three-arm trial, cluster randomised by household.

SETTING

Seven London-based general practices.

PARTICIPANTS

A total of 11,015 people without PA contraindications, aged 45-75 years, randomly selected from practices, were invited. A total of 6399 people were non-responders, and 548 people self-reporting achieving PA guidelines were excluded. A total of 1023 people from 922 households were randomised to usual care (n = 338), postal intervention (n = 339) or nurse support (n = 346). The recruitment rate was 10% (1023/10,467). A total of 956 participants (93%) provided outcome data.

INTERVENTIONS

Intervention groups received pedometers, 12-week walking programmes advising participants to gradually add '3000 steps in 30 minutes' most days weekly and PA diaries. The nurse group was offered three dedicated PA consultations.

MAIN OUTCOME MEASURES

The primary and main secondary outcomes were changes from baseline to 12 months in average daily step counts and time in MVPA (in ≥ 10-minute bouts), respectively, from 7-day accelerometry. Individual resource-use data informed the within-trial economic evaluation and the Markov model for simulating long-term cost-effectiveness. Qualitative evaluations assessed nurse and participant views. A 3-year follow-up was conducted.

RESULTS

Baseline average daily step count was 7479 [standard deviation (SD) 2671], average minutes per week in MVPA bouts was 94 minutes (SD 102 minutes) for those randomised. PA increased significantly at 12 months in both intervention groups compared with the control group, with no difference between interventions; additional steps per day were 642 steps [95% confidence interval (CI) 329 to 955 steps] for the postal group and 677 steps (95% CI 365 to 989 steps) for nurse support, and additional MVPA in bouts (minutes per week) was 33 minutes per week (95% CI 17 to 49 minutes per week) for the postal group and 35 minutes per week (95% CI 19 to 51 minutes per week) for nurse support. Intervention groups showed no increase in adverse events. Incremental cost per step was 19p and £3.61 per minute in a ≥ 10-minute MVPA bout for nurse support, whereas the postal group took more steps and cost less than the control group. The postal group had a 50% chance of being cost-effective at a £20,000 per quality-adjusted life-year (QALY) threshold within 1 year and had both lower costs [-£11M (95% CI -£12M to -£10M) per 100,000 population] and more QALYs [759 QALYs gained (95% CI 400 to 1247 QALYs)] than the nurse support and control groups in the long term. Participants and nurses found the interventions acceptable and enjoyable. Three-year follow-up data showed persistent intervention effects (nurse support plus postal vs. control) on steps per day [648 steps (95% CI 272 to 1024 steps)] and MVPA bouts [26 minutes per week (95% CI 8 to 44 minutes per week)].

LIMITATIONS

The 10% recruitment level, with lower levels in Asian and socioeconomically deprived participants, limits the generalisability of the findings. Assessors were unmasked to the group.

CONCLUSIONS

A primary care pedometer-based walking intervention in 45- to 75-year-olds increased 12-month step counts by around one-tenth, and time in MVPA bouts by around one-third, with similar effects for the nurse support and postal groups, and persistent 3-year effects. The postal intervention provides cost-effective, long-term quality-of-life benefits. A primary care pedometer intervention delivered by post could help address the public health physical inactivity challenge.

FUTURE WORK

Exploring different recruitment strategies to increase uptake. Integrating the Pedometer And Consultation Evaluation-UP (PACE-UP) trial with evolving PA monitoring technologies.

Delivery of a community-based nutrition education program for minority adults

BACKGROUND AND PURPOSE

Chronic diseases such as heart disease, type 2 diabetes, and obesity disproportionately affect minority adults, including African Americans. Engaging in lifestyle changes such as improving dietary habits and increasing physical activity can decrease the incidence and severity of these chronic diseases. The purpose of this research study was to explore the impact of a nutrition education program on health behaviors, lifestyle barriers, emotional eating, and body mass index (BMI) in a community-based setting with a minority sample.

METHODS

A convenience sample of 47 primarily African American adults participated in two similar Full Plate Diet nutrition interventions for 6 weeks (group I) and 8 weeks (group II). Participants completed pre-assessment and post-assessment of fruit, vegetable, and fat intake, as well as pre-assessment and post-assessment on physical activity, healthy lifestyle barriers, emotional eating, and BMI.

CONCLUSIONS

After intervention, there was a significant increase in intake of fruits and vegetables and decreased fat intake. No significant differences were found in physical activity, healthy lifestyle barriers, emotional eating, or BMI after the intervention.

IMPLICATIONS FOR PRACTICE

A structured, community-based nutrition education program may result in improved dietary habits among African Americans.

Randomized Controlled Trial of Lifestyle Walking for African American Women: Blood Pressure Outcomes

The aim of this study was to test the effects of a lifestyle physical activity intervention (group meetings alone vs supplemented by personal or automated calls) on changes in systolic/diastolic blood pressures from baseline to 24 and 48 weeks among African American women. This was a randomized controlled trial with intervention conditions randomly assigned across 6 community health care sites. Participants were 288 sedentary African American women without major signs/symptoms of cardiovascular disease. Each intervention had 6 group meetings over 48 weeks, with 1 of 3 options between meetings: (1) no calls, (2) personal motivational calls, or (3) automated motivational calls. Blood pressures were taken at baseline, 24 weeks, and 48 weeks. Separate analyses were conducted using blood pressure classifications from the 2003 and 2017 high blood pressure guidelines. Average blood pressures decreased approximately 3 mm Hg for systolic and 2 mm Hg for diastolic from baseline to 48 weeks, with no differences between conditions. For both 2003 and 2017 blood pressure classifications, the risk ratio (odds of moving to a lower classification) was 1.44 for each assessment (P < .001). This lifestyle walking intervention appears beneficial in lowering blood pressure across blood pressure classifications in midlife African American women.

Improving menopausal symptoms through promoting physical activity: a pilot Web-based intervention study among Asian Americans

OBJECTIVE

Based on previous studies, a Web-based physical activity promotion program with educational modules on menopausal symptoms and physical activity has been developed for Asian American midlife women to reduce their menopausal symptoms through increasing their physical activity. The purpose of this pilot randomized intervention study was to determine the efficacy of the Web-based program in improving menopausal symptom experience of Asian American midlife women.

METHODS

This was a randomized repeated measures pretest/posttest (pretest, post 1 month, and post 3 months) control group study among 29 Asian American midlife women. Multiple instruments were used, including the Midlife Women's Symptom Index and the Kaiser Physical Activity Survey. The data were analyzed using a mixed-model growth curve analysis.

RESULTS

Over time, total severity scores decreased for the control group (-0.53, P < 0.10), whereas they did not exhibit a meaningful change for the intervention group. Both study groups experienced improvement in active living habits over time, but such an improvement was greater for the intervention group (β = 0.29, P < 0.001) than for the control group (β = 0.08, P < 0.10). The time × group interactions for total severity scores were not statistically significant anymore after controlling for physical activity (-0.34 for the control group, P = 0.10).

CONCLUSIONS

The findings supported the feasibility of a 3-month Web-based intervention for menopausal symptom management among Asian American midlife women and the preliminary efficacy of the program in increasing their physical activity.

Interpreting population reach of a large, successful physical activity trial delivered through primary care

Background

Failure to include socio-economically deprived or ethnic minority groups in physical activity (PA) trials may limit representativeness and could lead to implementation of interventions that then increase health inequalities. Randomised intervention trials often have low recruitment rates and rarely assess recruitment bias. A previous trial by the same team using similar methods recruited 30% of the eligible population but was in an affluent setting with few non-white residents and was limited to those over 60 years of age.

Methods

PACE-UP is a large, effective, population-based walking trial in inactive 45-75 year-olds that recruited through seven London general practices. Anonymised practice demographic data were available for all those invited, enabling investigation of inequalities in trial recruitment. Non-participants were invited to complete a questionnaire.

Results

From 10,927 postal invitations, 1150 (10.5%) completed baseline assessment. Participation rate ratios (95% CI), adjusted for age and gender as appropriate, were lower in men 0.59 (0.52, 0.67) than women, in those under 55 compared with those ≥65, 0.60 (0.51, 0.71), in the most deprived quintile compared with the least deprived 0.52 (0.39, 0.70) and in Asian individuals compared with whites 0.62 (0.50, 0.76). Black individuals were equally likely to participate as white individuals. Participation was also associated with having a co-morbidity or some degree of health limitation. The most common reasons for non-participation were considering themselves as being too active or lack of time.

Conclusions

Conducting the trial in this diverse setting reduced overall response, with lower response in socio-economically deprived and Asian sub-groups. Trials with greater reach are likely to be more expensive in terms of recruitment and gains in generalizability need to be balanced with greater costs. Differential uptake of successful trial interventions may increase inequalities in PA levels and should be monitored.

Randomized Clinical Trial of the Women's Lifestyle Physical Activity Program for African-American Women: 24- and 48-Week Outcomes

PURPOSE

To compare the effects of a physical activity (PA) intervention of group meetings versus group meetings supplemented by personal calls or automated calls on the adoption and maintenance of PA and on weight stability among African-American women.

DESIGN

Randomized clinical trial with three conditions randomly assigned across six sites.

SETTING

Health settings in predominately African-American communities.

SUBJECTS

There were 288 women, aged 40 to 65, without major signs/symptoms of pulmonary/cardiovascular disease.

INTERVENTION

Six group meetings delivered over 48 weeks with either 11 personal motivational calls, 11 automated motivational messages, or no calls between meetings.

MEASURES

Measures included PA (questionnaires, accelerometer, aerobic fitness), weight, and body composition at baseline, 24 weeks, and 48 weeks.

ANALYSIS

Analysis of variance and mixed models.

RESULTS

Retention was 90% at 48 weeks. Adherence to PA increased significantly (p < .001) for questionnaire (d = .56, 128 min/wk), accelerometer (d = .37, 830 steps/d), and aerobic fitness (d = .41, 7 steps/2 min) at 24 weeks and was maintained at 48 weeks (p < .001), with no differences across conditions. Weight and body composition showed no significant changes over the course of the study.

CONCLUSION

Group meetings are a powerful intervention for increasing PA and preventing weight gain and may not need to be supplemented with telephone calls, which add costs and complexity.

Barriers to physical activity as moderators of intervention effects

The impact of interventions to increase physical activity (PA) may vary as a function of participants' barriers to PA. The aim of this paper is to determine whether individual barriers (demographic, physical health, psychological health, neighborhood factors, perceived barriers to PA, social support for PA) moderate treatment effects on increases in PA. Three treatment conditions tested the relative efficacy of a group-based PA intervention alone or supplemented by either personal or automated phone calls made between group meetings. From 2010 to 2012, 284 African American women (ages 40-65) living in the Chicago, IL, area were randomized to one of the three treatment conditions. Data collection occurred at baseline as well as 24 and 48 weeks after baseline. Moderation of intervention effects by barriers to PA were tested across four outcome measures (self-reported moderate-vigorous PA, self-reported walking, accelerometer steps, and aerobic fitness) using multilevel mixed-effects analyses. Significant condition by barrier interaction effects for the accelerometer steps outcome were found for material hardships, general health, depressive symptoms, neighborhood crime rate, and perceived barriers to PA. For aerobic fitness, intervention effects were moderated by material hardships and perceived pain. Increases in the outcome variables were greater for the conditions in which group sessions were supplemented with personal and/or automated calls. Among participants with greater barriers to PA, supplementing the intervention group meetings with between-session personal and/or automated phone calls may be an effective way to strengthen intervention effects. These results may inform the use of treatment supplements in the context of adaptive interventions.

Promoting Physical Activity among Underserved Populations

Underserved populations, including racial/ethnic minorities, individuals with low socioeconomic status, and individuals with physical disabilities, are less likely to engage in sufficient moderate to vigorous physical activity (MVPA) and are thus at increased risk of morbidity and mortality. These populations face unique challenges to engaging in MVPA. Learning how to overcome these challenges is a necessary first step in achieving health equity through health promotion research. In this review of the literature, we discuss issues and strategies that have been used to promote MVPA among individuals from underserved populations, focusing on recruitment, intervention delivery, and the use of technology in interventions. Physical activity promotion research among these vulnerable populations is scarce. Nevertheless, there is preliminary evidence of efficacy in the use of certain recruitment and intervention strategies including tailoring, cultural adaptation, incorporation of new technologies, and multilevel and community-based approaches for physical activity promotion among different underserved populations.

Cardiovascular Risk in Midlife African American Women Participating in a Lifestyle Physical Activity Program

BACKGROUND

Cardiovascular disease (CVD) is the largest contributor to disparate morbidity and mortality in African American women.

OBJECTIVE

The aims of this article are to describe in a cohort of sedentary, urban community-based midlife African American women eligible for a physical activity program their (1) CVD risk factors and (2) awareness, treatment, and control of hypertension and hypercholesterolemia.

METHODS

Cross-sectional baseline findings on 297 women were examined at baseline of a controlled physical activity clinical trial. Cardiovascular disease risks included hypertension, hypercholesterolemia, smoking, diabetes, and obesity. Among women with hypertension and hypercholesterolemia, rates of awareness, treatment, and control were calculated.

RESULTS

Our sample had significantly more hypertension and obesity than reported in other national samples of African American women. The women mirrored national samples of African American women: fewer than 60% had adequate control of hypertension. Versus national samples of African Americans (men/women combined), our study groups both showed significantly lower low-density-lipoprotein cholesterol level: treatment, 33% versus 63.8%, and control, 24.8% versus 45.3%.

CONCLUSIONS

Because national samples are more heterogeneous, our sample provides important information about CVD risks in inactive, urban community-dwelling, midlife African American women. Given the opportunity, many such women at elevated risk for CVD are willing to participate in a physical activity intervention. They must be identified and offered pharmacological and lifestyle interventions.

The Cost of Increasing Physical Activity and Maintaining Weight for Midlife Sedentary African American Women

OBJECTIVE

To evaluate the marginal costs of increasing physical activity and maintaining weight for a lifestyle physical activity program targeting sedentary African American women.

METHODS

Outcomes included change in minutes of total moderate to vigorous physical activity, leisure-time moderate to vigorous physical activity and walking per week, and weight stability between baseline and maintenance at 48 weeks. Marginal cost-effectiveness ratios (MCERs) were calculated for each outcome, and 95% confidence intervals (CIs) were computed using a bootstrap method. The analysis was carried out from the societal perspective and calculated in 2013 US dollars.

RESULTS

For the 260 participants in the analysis, program costs were $165 ± $19, and participant costs were $164 ± $35, for a total cost of $329 ± $49. The MCER for change in walking was $1.50/min/wk (95% CI 1.28-1.87), for change in moderate to vigorous physical activity was $1.73/min/wk (95% CI 1.41-2.18), and for leisure-time moderate to vigorous physical activity was $1.94/min/wk (95% CI 1.58-2.40). The MCER for steps based on the accelerometer was $0.46 per step (95% CI 0.30-0.85) and weight stability was $412 (95% CI 399-456).

CONCLUSIONS

The Women's Lifestyle Physical Activity Program is a relatively low-cost strategy for increasing physical activity. The marginal cost of increasing physical activity is lower than for weight stability. The participant costs related to time in the program were nearly half the total costs, suggesting that practitioners and policymakers should consider the participant cost when disseminating a lifestyle physical activity program into practice.

Retention of African American Women in a Lifestyle Physical Activity Program

The purpose of the article is to examine how well individual characteristics, neighborhood characteristics, and intervention participation predict study retention and staff level of effort needed for retention, using a cohort of African American women enrolled in a physical activity program. Secondary data analysis was conducted from a randomized clinical trial. Participants were aged 40 to 65 years without major signs/symptoms of cardiovascular disease. Assessments were conducted at community sites in/bordering African American communities. Study retention was 90%. Of those retained, 24% required moderate/high level of staff effort for retention. Retention was predicted by being older, having lower perceived neighborhood walkability, living in neighborhoods with greater disadvantage and crime, and having greater program participation. More staff effort was predicted by participants being younger, having more economic hardships, poorer health, or lower intervention participation. We may be able to identify people at baseline likely to require more staff effort to retain.

Effects of physical exercise programme on happiness among older people

This randomized-controlled trial investigated the effect of physical exercise programme (PEP) on happiness among older adults in Nowshahr, Iran. Results of this study on 120 male and female volunteers showed that an 8-week group physical exercise programme was significantly effective in older adults' happiness. Findings showed that physical exercise programme is so beneficial for increasing older adults' happiness. Physical activity is associated with well-being and happiness. The purpose of this study was to determine the effects of an 8-week long physical exercise programme (PEP) on happiness among older adults in Nowshahr, Iran. This was a randomized control trial study. The participants consisted of a group of 120 male and female volunteers (mean ± SD age: 71 ± 5.86 years) in a convenience sampling among older adults in public parks in Nowshahr, Iran. We randomly allocated them into experimental (n = 60) and control (n = 60) groups. A validated instrument was used to measure well-being and happiness [Oxford Happiness Inventory (OHI)]. Respondents were asked to complete the OHI before and 2 months after implementing PEP. The 8-week PEP was implemented with the intervention group. The statistical analysis of the data was conducted using paired t-test, Fisher's exact test and χ(2). Before the intervention, there was no significant difference in the happiness mean score between the case and control groups; however, after implementing PEP, happiness significantly improved among the experimental group (P = 0.001) and did not improve within the control group (P = 0.79). It can be concluded that PEP had positive effects on happiness among older adults. Planning and implementing of physical activity is so important for older happiness.
