Reporting of Physical Activity Device Measurement and Analysis Protocols in Lifestyle Interventions

This systematic review examined the extent to which lifestyle physical activity interventions that used wearable devices (eg, pedometers, accelerometers) reported on the length of device wear time requested in their protocols, criteria for analytic inclusion of data, and participant compliance with device use protocols. Literature were searches were conducted using PubMed, Cochrane Central Register, and PsychInfo. Studies were included if they were the main outcomes paper of a trial that reported on a randomized or quasi-randomized trial focused on increasing lifestyle physical activity and were published between January 1, 2006 and March 30, 2016. Titles and abstracts were screened by 2 independent reviewers; eligible full texts were retrieved and reviewed by 2 independent reviewers. A total of 104 studies used wearable devices (n = 57 pedometers, n = 47 accelerometers). Most studies (n = 65, 67.3%) asked participants to wear devices for 7 days. Almost half of the studies (n = 46, 44.2%) did not report minimum device wear time required for analytic inclusion of data, and variation existed among studies reporting these criteria. Most studies (n = 60, 57.7%) did not report average device wear time, or participant compliance with device wear. Overall, there was heterogeneity in reporting of physical activity device data. Refinement and streamlining of guidelines for device use, analysis, and reporting of data could improve comparability across studies.

Considering religion and spirituality in precision medicine

The emerging era of precision medicine (PM) holds great promise for patient care by considering individual, environmental, and lifestyle factors to optimize treatment. Context is centrally important to PM, yet, to date, little attention has been given to the unique context of religion and spirituality (R/S) and their applicability to PM. R/S can support and reinforce health beliefs and behaviors that affect health outcomes. The purpose of this article is to discuss how R/S can be considered in PM at multiple levels of context and recommend strategies for integrating R/S in PM. We conducted a descriptive, integrative literature review of R/S at the individual, institutional, and societal levels, with the aim of focusing on R/S factors with a high level of salience to PM. We discuss the utility of considering R/S in the suitability and uptake of PM prevention and treatment strategies by providing specific examples of how R/S influences health beliefs and practices at each level. We also propose future directions in research and practice to foster greater understanding and integration of R/S to enhance the acceptability and patient responsiveness of PM research approaches and clinical practices. Elucidating the context of R/S and its value to PM can advance efforts toward a more whole-person and patient-centered approach to improve individual and population health.

Recruiting low-income postpartum women into two weight loss interventions: in-person versus Facebook delivery

Several studies, such as the Diabetes Prevention Program (DPP), have provided foundational evidence for the efficacy of lifestyle interventions on weight loss and cardiometabolic prevention. However, translating these interventions to real-world settings and engaging at-risk populations has proven difficult. Social media-delivered interventions have high potential for reaching high-risk populations, but there remains a need to understand the extent to which these groups are interested in social media as a delivery mode. One potential way to this is by examining recruitment rates as a proxy for interest in the intervention delivery format. The aim of this study was to describe the recruitment rates of overweight and obese low-income postpartum women into two asynchronous behavioral weight loss interventions: one delivered in-person and the other delivered via Facebook. Both interventions used the same recruitment methods: participants were overweight low-income postpartum women who were clients of Women, Infants, and Children (WIC) clinics in Worcester, MA, screened for the study by nutritionists during routine WIC visits. Similarly, eligibility criteria were the same for both interventions except for a requirement for the Facebook-delivered intervention to currently use Facebook at least once per week. Among women pre-eligible for the in-person intervention, 42.6% gave permission to be contacted to determine full eligibility and 24.1% of eligible women enrolled. Among women pre-eligible for the Facebook intervention, 31.8% gave permission to be contacted and 28.5% of eligible women enrolled. Recruitment rates for a Facebook-based weight loss intervention were similar to recruitment rates for an in-person intervention, suggesting similar interest in the two program delivery modes among low-income postpartum women.

An Evaluation of Lifestyle Health Coaching Programs Using Trained Health Coaches and Evidence-Based Curricula at 6 Months Over 6 Years

PURPOSE

Describe health plan member-level participation, completion, and 6-month outcomes for 5 lifestyle health coaching programs offered by an integrated delivery and financing system (IDFS) over 6 years.

DESIGN

Case series study of 5 lifestyle programs with 180-day follow-up.

SETTING

Large Western PA integrated delivery and financing system (IDFS) deployed multiple coaching modalities for diverse insurance-member enrolled population.

PARTICIPANTS

A total of 14 591 health plan members choosing a lifestyle health coaching program.

INTERVENTION

Evidence- and curriculum-based lifestyle health coaching programs delivered by 1 of 4 interactive modalities.

MEASURES

A single metric was used as an overall indicator of clinical success for each program. Success measures include a ≥5% reduction of self-reported baseline weight, meeting physical activity guidelines, and 7-day point prevalence abstinence from tobacco. For stress and nutrition, where no single target measure exists, a metric was created that represented a net improvement across all key outcomes measured.

ANALYSIS

The proportion of members meeting target outcomes were calculated and described across all time points and modalities.

RESULTS

At 180 days, 77% of enrolled members reported reduced stress, 7% quit tobacco, 50.5% met physical activity guidelines, 65.2% improved nutrition, and 44.2% lost 5% or more of baseline weight.

CONCLUSION

This evaluation describes the real-world effectiveness of evidence- and curriculum-based lifestyle improvement programs delivered by trained health coaches to a diverse health plan member population.

Interest in and barriers to participation in a Facebook-delivered weight loss program among female cancer survivors with overweight or obesity

BACKGROUND

Although excess body weight is linked to post-treatment complications for cancer survivors, obesity rates have increased rapidly among adult cancer survivors. Innovative approaches to weight loss programs, such as via social media, are needed to engage female cancer survivors. The purpose of this study is to explore important components of a Facebook-delivered weight loss program for female cancer survivors.

METHODS

Female cancer survivors who are overweight or obese and finished active treatment completed a web-based, mixed-methods survey.

RESULTS

Participants (N=96) were on average 54.3±9.6 years old, 89% white, 66% obese, and 87% tried to lose weight in the last year. Health concerns were the most important reason (88%) for wanting to lose weight. Barriers to weight loss included other health issues (52%) and perceived sacrifice/burden of weight loss process (35%). Qualitative themes for barriers included inability to make dietary changes (19%), lack of motivation (18%), and physical limitations (13%). Participants were most interested in a weight loss program delivered via Facebook (81%), led by a weight loss counselor (78%), provided healthy recipes (73%) and exercise videos (72%). Qualitative themes included information on cancer treatment effects (25%), calorie tracker (21%), and exercise modifications (17%). Qualitatively, concerns about weight loss included fear of cancer recurrence (20%) and lack of confidence in weight loss efforts (17%).

CONCLUSIONS

While female cancer survivors are interested in a Facebook-delivered weight loss program, additional research needs to address customization and delivery to address specific barriers experienced by cancer survivors.

Adapting a Behavioral Weight Loss Intervention for Delivery via Facebook: A Pilot Series Among Low-Income Postpartum Women

Background

Efforts to translate evidence-based weight loss interventions, such as the Diabetes Prevention Program (DPP), to low-income postpartum women have resulted in poor intervention attendance and high attrition. Strategies that improve engagement and retention in this population are needed to maximize the reach of evidence-based weight loss interventions.

Objective

The objective of this study was to adapt a DPP-based weight loss intervention (Fresh Start) for Facebook delivery and to evaluate its feasibility among low-income postpartum women.

Methods

This study comprised 3 single-group pilot studies where feasibility outcomes iteratively informed changes from one pilot to the next. We paralleled the in-person program for Facebook delivery by translating the protocol to a content library of Facebook posts with additional posts from lifestyle coaches. Low-income postpartum women were recruited from Women, Infants, and Children (WIC) clinics in Worcester, Massachusetts. Participants were enrolled into a 16-week weight loss intervention delivered via Facebook. During the first 8 weeks, Facebook intervention posts were delivered 2 times per day, with additional posts from coaches aiming to stimulate interaction among participants or respond to participants’ questions and challenges. For the following 8 weeks, posts were delivered once per day without additional coaching. Feasibility outcomes were engagement (defined by number of likes, comments, and posts measured throughout intervention delivery), acceptability, and retention (survey at follow-up and assessment completion rate, respectively). Changes in weight were also assessed at baseline and follow-up.

Results

Pilot 1 had a retention rate of 89% (24/27), and on average, 62% (17/27) of women actively engaged with the group each week during the 8-week coached phase. Mean weight loss was 2.6 (SD 8.64) pounds, and 79% (19/27) would recommend the program to a friend. Pilot 2 had a retention rate of 83% (20/24), and on average, 55% (13/24) of women actively engaged with the group weekly during the 8-week coached phase. Mean weight loss was 2.5 (SD 9.23) pounds, and 80% (16/24) would recommend the program to a friend. Pilot 3 had a retention rate of 88% (14/16), and on average, 67% (11/16) of women actively engaged with the group weekly during the 8-week coached phase. Mean weight loss was 7.0 (SD 11.6) pounds, and 100% (16/16) would recommend the program to a friend.

Conclusions

Our findings demonstrated that a Facebook-delivered intervention was acceptable and could be feasibly delivered to low-income postpartum women. Future research is needed to evaluate the efficacy of a Facebook-delivered weight loss intervention.

Does provider advice to increase physical activity differ by activity level among US adults with cardiovascular disease risk factors?

Background

Regular physical activity (PA) lowers the risk of cardiovascular disease (CVD), but few US adults meet PA guidelines. The United States Preventive Services Task Force (USPSTF) recommends primary care providers offer PA counselling for CVD prevention. We examined the association between adherence to PA guidelines and reported provider advice to increase PA among US adults with overweight/obesity and ≥1 additional CVD risk factor.

Methods

Cross-sectional data from the National Health and Nutrition Examination Survey (2011-2014) on PA and provider advice to increase PA were analysed for 4158 adults (≥20 years old) with overweight/obesity who reported ≥1 of hypertension, high cholesterol or impaired fasting glucose. Adherence to federal PA guidelines was determined using self-reported PA data from the Global Physical Activity Questionnaire. Meeting PA guidelines was defined as ≥150 minutes/week moderate intensity PA, ≥75 minutes/week vigorous intensity, or an equivalent combination. Participants self-reported provider advice to increase PA.

Results

In total, 57.7% of US adults with overweight/obesity and ≥1 additional CVD risk factor who did not meet PA guidelines reported provider advice to increase PA compared to 49.7% of adults who met PA guidelines. Adults who did not meet PA guidelines were more likely to report provider PA advice (aOR = 1.21; 95% CI = 1.00-1.47).

Conclusions

US adults with CVD risk factors who do not meet PA guidelines are more likely to receive provider advice to increase PA, but only half receive such advice. Strategies to increase provider advice are needed to improve adherence to USPSTF guidelines among US adults with overweight/obesity and additional CVD risk factors.

Racial/ethnic representation in lifestyle weight loss intervention studies in the United States: A systematic review

Obesity remains a persistent public health and health disparity concern in the United States. Eliminating health disparities, particularly among racial/ethnic minority groups, is a major health priority in the US. The primary aim of this review was to evaluate representation of racial/ethnic sub-group members in behavioral weight loss interventions conducted among adults in the United States. The secondary aims were to assess recruitment and study design approaches to include racial/ethnic groups and the extent of racial/ethnic sub-group analyses conducted in these studies. PubMed, PsycInfo, Medline, and CINAHL were searched for behavioral weight loss intervention trials conducted in 2009–2015 using keywords: weight, loss, overweight, obese, intervention and trial. Most of the 94 studies included a majority of White participants compared to any other racial/ethnic group. Across the included studies, 58.9% of participants were White, 18.2% were African American, 8.7% were Hispanic/Latino, 5.0% were Asian and 1.0% were Native Americans. An additional 8.2% were categorized as “Other”. Nine of the 94 studies exclusively included minority samples. Lack of adequate representation of racial and ethnic minority populations in behavioral trials limits the generalizability and potential public health impact of these interventions to groups that might most benefit from weight loss. Given racial/ethnic disparities in obesity rates and the burden of obesity and obesity-related diseases among minority groups in the United States, greater inclusion in weight loss intervention studies is warranted.

•

Describes racial/ethnic minority inclusion in behavioral weight loss studies

•

Majority of studies continue to include a majority white sample.

•

Modest increases in the representation of some racial/ethnic minority groups.

•

Lack of adequate representation of minority groups limits generalizability.

•

Greater racial/ethnic inclusion in weight loss intervention studies is warranted.

Weight Perceptions and Weight-Related Behaviors among Low Income Postpartum Women

Background

Minority and low-income women have higher rates of postpartum weight retention, contributing to increased rates of obesity in these populations. Weight perceptions may be an important factor contributing to the adoption of weight-management behaviors. The purpose of this study was to examine the relationships between weight perceptions and weight-related behaviors among overweight low-income women during postpartum enrolled in a weight loss intervention study.

Methods

This is a cross-sectional analysis of the Fresh Start study baseline data among overweight and obese low-income women during postpartum (N = 132). General linear regression models assessed the association between weight perceptions and energy intake, energy expenditure, self-monitoring, and self-regulation.

Results

Women who perceived themselves to be very overweight had significantly lower self-regulation (β = -4.0, SE = 1.6, p = 0.014) and higher energy expenditure (β = 1.3, SE = 0.7, p = 0.05) compared to women who perceived themselves to be moderately overweight or a little overweight. There were no significant associations between weight perceptions and self-monitoring or energy intake.

Conclusions

This study found that weight perceptions among these women are important factors to consider for weight loss. Future research should focus on investigating the impact of tailoring interventions to weight perceptions to impact engagement in weight-related behaviors in diverse low-income women during postpartum.

Methods for Evaluating the Content, Usability, and Efficacy of Commercial Mobile Health Apps

Commercial mobile apps for health behavior change are flourishing in the marketplace, but little evidence exists to support their use. This paper summarizes methods for evaluating the content, usability, and efficacy of commercially available health apps. Content analyses can be used to compare app features with clinical guidelines, evidence-based protocols, and behavior change techniques. Usability testing can establish how well an app functions and serves its intended purpose for a target population. Observational studies can explore the association between use and clinical and behavioral outcomes. Finally, efficacy testing can establish whether a commercial app impacts an outcome of interest via a variety of study designs, including randomized trials, multiphase optimization studies, and N-of-1 studies. Evidence in all these forms would increase adoption of commercial apps in clinical practice, inform the development of the next generation of apps, and ultimately increase the impact of commercial apps.

Spirituality and Physical Activity and Sedentary Behavior among Latino Men and Women in Massachusetts

INTRODUCTION

To examine the relationships between spirituality and physical activity and sedentary behavior in a sample of Latino adults in Massachusetts.

DESIGN

This is a cross-sectional analysis of the Lawrence Health and Well Being Study; a study that was conducted among patients at the Greater Lawrence Family Health Center (GLFHC) in Lawrence, Massachusetts.

PARTICIPANTS

602 Latino or Hispanic adults aged 21 to 85 years completed the study.

RESULTS

There was a significant negative relationship between spirituality and sedentary behavior (β= -.12, p = .004). Although not statistically significant, higher spirituality was associated with increased odds of engaging in physical activity. There were no significant associations between spirituality and physical activity among men or women. Men with greater spirituality were significantly less sedentary (β = -.17, P = .005). There was no relationship between sedentary behavior and spirituality among women.

CONCLUSIONS

This study found that individuals who are more spiritual are also less sedentary, and this association was stronger in men than women. Findings provide insight for developing future interventions to promote activity in this high-risk population, which has been greatly understudied. Future research endeavors should consider investigating the impact of spirituality-based messages to reduce sedentary behavior among Latinos.

Neighborhood environment correlates of physical activity and sedentary behavior among Latino adults in Massachusetts

Background

U.S. Latinos experience high rates of cardio-metabolic diseases and have high rates of physical inactivity and sedentary behavior. Understanding the environmental factors associated with physical activity and sedentary behaviors among Latinos could inform future interventions. The purpose of this study is to explore the neighborhood environment correlates of physical activity and sedentary behavior in a sample of U.S. Latino adults.

Methods

Cross-sectional study of 602 Latino adults in Lawrence, MA. Survey assessments of physical activity, sedentary behavior, and neighborhood environment were verbally administered. The neighborhood environment scale assessed violence, safety, aesthetic quality, walkability, availability of healthy foods, social cohesion, and activities with neighbors.

Results

After controlling forage, gender, education, body mass index (BMI), and smoking status, two variables were associated with the outcomes of interest. Living in more walkable neighborhoods was associated with an increased likelihood of engaging in adequate levels of physical activity (>150 min per week, as recommended by the American College of Sports Medicine (ACSM)) (OR = 1.403, p = .018); and greater frequency of activities with neighbors was associated with greater sedentary behavior (β = .072, p = .05).

Conclusions

There were different neighborhood environment correlates of physical activity and sedentary behavior in this Latino community. Focusing on a greater understanding of the distinct social and physical environmental correlates of physical activity and sedentary behavior may provide important insights for reducing CVD risk and health disparities among Latinos.
