Cadence as a Behavioral Target in Physical Activity Interventions: A Narrative Review.

Behavioral interventions targeting moderate- to vigorous-intensity physical activity (MVPA) to ensure health benefits can be strengthened by a simple metric that helps adults understand if they are exercising at the target intensity. Laboratory studies have established that a cadence of 100 steps/min is equivalent to MVPA, but intervention application is largely unexplored. The aim of this narrative review was to describe how cadence has been implemented in behavioral interventions.

A look into the cancer continuum for the development of a physical activity intervention: qualitative investigation of the physical activity experiences and preferences of female cancer survivors.

Purpose: Clinical guidelines recommend cancer survivors (i.e., people with a cancer diagnosis) engage in regular physical activity (PA) during and post treatment, yet most do not.

The recent history and near future of digital health in the field of behavioral medicine: an update on progress from 2019 to 2024.

The field of behavioral medicine has a long and successful history of leveraging digital health tools to promote health behavior change. Our 2019 summary of the history and future of digital health in behavioral medicine (Arigo in J Behav Med 8: 67-83, 2019) was one of the most highly cited articles in the Journal of Behavioral Medicine from 2010 to 2020; here, we provide an update on the opportunities and challenges we identified in 2019. We address the impact of the COVID-19 pandemic on behavioral medicine research and practice and highlight some of the digital health advances it prompted.

Addressing Susceptibility to Non-Prescription Substances for Weight Loss Among Immigrant Hispanic College Students: A Pilot Study.

Non-prescription weight loss substances, such as supplements and herbal remedies, can be harmful. Hispanic immigrant students may be highly susceptible to these substances, especially those advertised on social media. This study was a feasibility/acceptability pilot trial of an intervention to reduce this susceptibility.

Lifetime Exposure to Cigarette Smoke, B-Cell Tumor Immune Infiltration, and Immunoglobulin Abundance in Ovarian Tumors.

Background: Cigarette smoke exposure has been linked to systemic immune dysfunction, including for B-cell and immunoglobulin (Ig) production, and poor outcomes in patients with ovarian cancer. No study has evaluated the impact of smoke exposure across the life-course on B-cell infiltration and Ig abundance in ovarian tumors.

Methods: We measured markers of B and plasma cells and Ig isotypes using multiplex immunofluorescence on 395 ovarian cancer tumors in the Nurses' Health Study (NHS)/NHSII.

Harnessing technology and gamification to increase adult physical activity: a cluster randomized controlled trial of the Columbia Moves pilot.

Background: The use of health technologies and gamification to promote physical activity has increasingly been examined, representing an opportunistic method for harnessing social support inherent within existing social ties. However, these prior studies have yielded mixed findings and lacked long-term follow-up periods. Thus, a pilot cluster randomized controlled trial was conducted to gauge the feasibility and preliminary efficacy of a digital gamification-based physical activity promotion approach among teams of insufficiently active adults with existing social ties.

BabyByte: Qualitative Research to Inform the Development of an App to Improve Responsive Feeding Practices in Parents of Infants and Toddlers.

Responsive feeding is associated with a reduced risk of childhood obesity. The objective of this qualitative study was to determine parental preferences for mobile health (mHealth) app content and features designed to improve responsive feeding practices. Parents of 0-2-year-old children were interviewed individually.

The Relationship Between How Participants Articulate Their Goals and Accomplishments and Weight Loss Outcomes: Secondary Analysis of a Pilot of a Web-Based Weight Loss Intervention.

Background: In behavioral weight loss interventions, participants are asked to set weekly goals to support long-term habits that lead to weight loss. Although participants are asked to set and accomplish weekly goals, we do not know how often they do this and whether doing so is associated with weight loss. Web-based weight loss interventions allow for the analysis of participant engagement data, including how participants articulate their goals and accomplishments.

Pre-Enrollment Steps and Run-Ins in Weight Loss Trials: A Meta-Regression.

Introduction: The generalizability of study findings may be influenced by pre-enrollment trial procedures, including the use of behavioral run-in periods. The study goals were to determine whether behavioral run-in periods and other pre-enrollment processes affect outcomes in randomized trials of behavioral weight loss interventions that have contributed to clinical guidelines.

Methods: The sample was behavioral weight loss intervention trials included in the 2018 U.

Behavior change techniques in digital physical activity interventions for breast cancer survivors: a systematic review.

Given the broad benefits of physical activity (PA) but low PA levels among breast cancer survivors (i.e., women who have received a breast cancer diagnosis), innovative and evidence-based techniques are needed to motivate and support exercise.

Lifetime Exposure to Cigarette Smoke and Risk of Ovarian Cancer by T-cell Tumor Immune Infiltration.

Background: Exposure to cigarette smoke, particularly in early life, is modestly associated with ovarian cancer risk and may impact systemic immunity and the tumor immune response. However, no studies have evaluated whether cigarette smoke exposure impacts the ovarian tumor immune microenvironment.

Methods: Participants in the Nurses' Health Study (NHS) and NHSII reported on early life exposure to cigarette smoke and personal smoking history on questionnaires (n = 165,760).

Privacy Concerns in Group Format Lifestyle Interventions for Obesity.

Background: Group format weight loss interventions have benefits over individual format, but privacy concerns may limit their uptake.

Method: In this study, adults with obesity and interest in losing weight were recruited nationally online and randomly assigned to view one of eight videos describing a hypothetical, group behavioral weight loss intervention. Based on three fully crossed factors, the videos varied on privacy features of intervention (present or not); matching participants to group based on weight loss barriers (matched or not); and intervention format (online or in-person).

Engaging primary care patients with existing online tools for weight loss: A pilot trial.

Objective: Free online tools show potential for promoting weight loss at a low cost, but there is limited evidence about how to effectively engage patients with them. To address this, a low-dose, flexible intervention was developed that aims to enhance weight-related discussions with primary care providers (PCPs) and engage patients with an organic (i.e.

Relative reinforcement from physical activity in real-world environments: a novel application of behavioral economics.

Behavioral economics suggests that individuals are likely to engage in a behavior if it is more reinforcing and readily available than other possible options. In real-world environments, sedentary behaviors are often more reinforcing and easily available than physical activities. In order to promote regular physical activity in an environment with sedentary alternatives, it is important to understand the proportion of overall reinforcement that is derived from physical activity (i.

Engaging adults with obesity in organic online communities to support weight loss: a mixed methods pilot study.

Objectives: Organic online communities have shown potential for aiding weight loss, but few adults use them. We sought to test strategies to encourage adults to select and engage in online communities for weight loss.

Design: 4-week single-arm, mixed-methods pilot.

The Faith, Activity, and Nutrition (FAN) dissemination and implementation study: changes in and maintenance of organizational practices over 24 months in a statewide initiative.

Background: Few studies have examined the impact of ecological health promotion interventions on organizational practices over time, especially in faith-based settings. This statewide dissemination and implementation study examined change in organizational practices and their predictors across a 24-month period, as well as maintenance of change.

Methods: Using a pre-post quasi-experimental design, church coordinators from 92 United Methodist Churches in South Carolina (42% predominantly African American congregations) completed surveys at baseline, and immediate, 12-, and 24-months post-training regarding physical activity (PA) and healthy eating (HE) organizational practices consistent with the Faith, Activity, and Nutrition (FAN) program (opportunities, policies, pastor support, messages) and possible predictors.

Lessons Learned: Beta-Testing the Digital Health Checklist for Researchers Prompts a Call to Action by Behavioral Scientists.

Digital technologies offer unique opportunities for health research. For example, Twitter posts can support public health surveillance to identify outbreaks (eg, influenza and COVID-19), and a wearable fitness tracker can provide real-time data collection to assess the effectiveness of a behavior change intervention. With these opportunities, it is necessary to consider the potential risks and benefits to research participants when using digital tools or strategies.

Methods-Motivational Interviewing Approach for Enhanced Retention and Attendance.

Introduction: Suboptimal and differential participant engagement in randomized trials-including retention at primary outcome assessments and attendance at intervention sessions-undermines rigor, internal validity, and trial conclusions.

Methods: First, this study describes Methods-Motivational Interviewing approach and strategies for implementation. This approach engages potential participants before randomization through interactive, prerequisite orientation sessions that illustrate the scientific rationale behind trial methods in accessible language and use motivational interviewing to diffuse ambivalence about participation.

Early life physical activity and risk of ovarian cancer in adulthood.

Emerging data suggest that exposures in early life may affect ovarian development and contribute to ovarian cancer risk. We evaluated the association between early life physical activity and risk of ovarian cancer in adulthood in two large prospective cohorts, the Nurses' Health Study (NHS) and NHSII. In total, analyses included 28 232 NHS participants (followed from 2004 to 2016) and 56 553 NHSII participants (followed from 1997 to 2017).

Use of Fitbit Devices in Physical Activity Intervention Studies Across the Life Course: Narrative Review.

Background: Commercial off-the-shelf activity trackers (eg, Fitbit) allow users to self-monitor their daily physical activity (PA), including the number of steps, type of PA, amount of sleep, and other features. Fitbits have been used as both measurement and intervention tools. However, it is not clear how they are being incorporated into PA intervention studies, and their use in specific age groups across the life course is not well understood.

Protocol for a randomized controlled feasibility study of a coordinated parent/child weight loss intervention: Dyad Plus.

Unlabelled: The prevalence of in youth with overweight and obesity is a global health concern, necessitating clinical interventions to treat obesity effectively through lifestyle modification. Interventions in adolescents have demonstrated improvements in healthy eating and physical activity with only modest weight loss outcomes. Consequently, there is growing interest in developing strategies to enhance the effectiveness of clinical interventions in adolescents.

Pathways of influences leading to adoption of the Faith, Activity and Nutrition (FAN) program in a statewide initiative.

RE-AIM (Reach, effectiveness, Adoption, Implementation, Maintenance) and CFIR (Consolidated Framework for Implementation Research) are complementary frameworks guiding research on dissemination and implementation of evidence-based interventions and factors influencing this process. Faith, Activity, and Nutrition (FAN) is an evidence-based program that increased physical activity and fruit and vegetable intake in faith-based settings. The aims of this adoption study were to quantify state-wide church level adoption rates and congregant reach of FAN in accordance with RE-AIM guidelines, and to explore the association of CFIR-derived constructs of the church inner setting and pastor characteristics with FAN adoption.

Early life exposure to tobacco smoke and ovarian cancer risk in adulthood.

Background: Ovarian cancer risk in adulthood may be affected by early life exposure to tobacco smoke. We investigated this relationship in two large prospective cohorts, the Nurses' Health Study (NHS) and NHSII.

Methods: In total, analyses included 110 305 NHS participants (1976-2016) and 112 859 NHSII participants (1989-2017).

Effects of sleep deprivation on endothelial function in adult humans: a systematic review.

Sleep deprivation is highly prevalent and is associated with increased cardiovascular disease (CVD) morbidity and mortality. Age-related alterations in sleep and chronobiology may exaggerate CVD susceptibility in older individuals. The mechanisms responsible for the association between sleep deprivation and CVD are not fully understood, but endothelial dysfunction may play a central role.

Using the Design Sprint process to enhance and accelerate behavioral medicine progress: a case study and guidance.

While challenges in the translation of behavioral medicine knowledge from academic settings to real-world use are well documented, they could potentially be reduced through the use of the Design Sprint process, a roadmap that facilitates progression from an idea to a product in 5 days via agile design and user-centered design principles. The Design Sprint is well aligned with several priorities of and methods common in behavioral medicine, including obtaining end-user feedback and thinking about implementation during intervention development. The Design Sprint could be used by behavioral medicine researchers for the development of research tools, implementation strategies, and behavior change interventions.
