Pasos Hacia La Salud II: A Superiority RCT Utilizing Technology to Promote Physical Activity in Latinas.

INTRODUCTION: Latinas face an increased risk for chronic diseases associated with insufficient physical activity (PA). The researchers previously showed that a website-based intervention could increase PA among insufficiently active Latinas, yet rates of meeting national PA guidelines were low. The original intervention was enhanced by adding additional features, content, and points of contact, including via text messaging. This study tests the efficacy of the enhanced intervention compared with the original, aimed at maximizing and sustaining PA gains across 24 months. It also examines if increases in PA differed by baseline PA. STUDY DESIGN: The researchers conducted a superiority randomized controlled trial (data collected 2018-2022, analyzed 2023). SETTING/PARTICIPANTS: Participants were 195 Spanish-speaking Latinas ages 18-65 in the Providence, RI area. INTERVENTION: The original intervention is an empirically supported Spanish-language, individually-tailored, website-delivered PA intervention. The enhanced intervention includes text messaging and additional data-driven content and interactive features. MAIN OUTCOME MEASURES: Total weekly minutes of moderate to vigorous PA (MVPA) was measured via accelerometry and self-report at 6, 12, 18, and 24 months. RESULTS: Participants in both groups increased their MVPA over 24 months. There were no significant between-group differences at 6 or 12 months; at 18 months the enhanced intervention group had higher levels of self-reported (mean (sd): 90.35 (43.55) vs 70.18 [9.99]) and accelerometer-measured (66.21 [18.26] vs 60.27 [16.00]) MVPA compared to the original intervention group. They also had higher levels of self-reported (111.17 [23.35] vs 81.44 [1.82]) and accelerometer-measured (63.76 [15.12] vs 54.86 [14.59]) MVPA at 24 months. Baseline PA moderated the intervention effect. CONCLUSIONS: This study demonstrates the potential to enhance the efficacy of website-based PA interventions by utilizing text messaging, and adding more interactive features, content, and phone support. These enhancements may be particularly beneficial in supporting long-term PA maintenance. TRIAL REGISTRATION: This study is registered at www. CLINICALTRIAL: gov (NCT03491592).

Perceived delivery of essential yoga properties within in-person and remote weight loss maintenance interventions.

OBJECTIVES: While previous research has utilized remote delivery of yoga interventions, no research has specifically interrogated the effectiveness of remote yoga intervention delivery. In this secondary analysis of weight-maintenance trial data, we examined participant perceptions of essential yoga properties across in-person and remote formats, hypothesizing that perceptions would not differ following remote delivery. METHODS: 24 women with overweight or obesity (34.6±4.1 kg/m2, 48.2±9.9 years) received a 12-week Iyengar yoga intervention (2x/week) following a 3-month behavioral weight loss program. Of 23 participants who completed follow-up questionnaires, 12 received the planned in-person intervention and 11 received a remote intervention (delivered live) due to the COVID-19 pandemic. The Essential Properties of Yoga Questionnaire (EPYQ) was completed online by participants and by the instructors to measure the perceptions of the relative emphasis placed on the essential components of the yoga intervention via 14 subscales. Linear regression models were used to compare perceptions of each EPYQ dimension across in-person and remote delivery methods, as well as between participants and instructors, independent of delivery method. RESULTS: 13 of the 14 subscales did not differ between delivery modalities (p>0.05). Participants perceived more individual attention within in-person yoga (p = 0.003). For both delivery methods, instructors perceived breathwork, restorative postures, and body locks to be incorporated to a lesser degree compared to participants (ß = -1.28, p = 0.003; ß = -1.57, p = 0.019; ß = -1.39, p = 0.036; respectively). No other significant differences across the participant and instructor scores were observed. CONCLUSIONS: Findings provide preliminary support for the use of live remote delivery of yoga, effectively communicating most essential yoga properties when compared to in-person classes. However, participants perceived more individual attention with in-person versus remote delivery; thus, future remote-based yoga interventions may benefit from providing additional individualized feedback.

Assessing Hair Concerns and Physical Activity Measures Among African American Women: a Mixed-Method Exploratory Study.

OBJECTIVES: Research on the association between hair concerns and physical activity (PA) constructs among African American (AA) women is lacking. Demographics such as age and income are indicated to influence hair concerns. In this study, quantitative methods were used to assess demographic differences in hair concerns and associations between hair concerns and PA. Qualitative interviewing explored AA women's views about their hair and engagement in PA. METHODS: Participants (n = 48; M age = 37.57, SD = 13.72) completed a survey that included demographics, hair type and hairstyle management (HTHM), decisional balance (pros, cons), perceived benefits and perceived barriers scale, and level of physical activity. HTHM consists of six items measuring different factors related to hair concerns. 25 completed a qualitative interview. Chi-square or analysis of variance tests were conducted as appropriate. Qualitative data were analyzed using content analysis. RESULTS: Proportion differences were noted between age groups (≤ 32 vs. ≥ 33) and average cost of haircare per month (p = .048). A statistically significant effect was noted for average monthly haircare cost and pros (p = .05), and for alter behavior due to hair concerns and perceived benefits to physical activity (p = .05). For level of physical activity, proportion differences were noted between exercisers and non-exercisers for average minutes spent on hair care (p = .009). Qualitative results showed few participants view hair concern as an important barrier to PA. Some participants suggested strategies for overcoming hair concerns to exercise (e.g., braids, twists). CONCLUSION: Implications of findings including development of PA intervention approaches that may appeal to AA women are discussed.

Technology-Based Smoking Cessation for Youth Exiting Foster Care: A Pilot Randomized Trial.

Despite high rates of cigarette use, little attention has been paid to screening and cessation services for youth in foster care. Study aims were to test the feasibility, acceptability, and preliminary efficacy of a technology-based smoking cessation intervention. Study enrollment, satisfaction, and engagement were high in the intervention arm, where readiness to change also significantly increased over time. Intervention and control participants significantly reduced cigarette use at 6-month follow up, though groups did not differ. Technology-based interventions appear to be attractive and offer a potentially scalable link to health care that this vulnerable population may not otherwise seek.

A randomized trial examining the effect of yoga on dietary lapses and lapse triggers following behavioral weight loss treatment.

Background: Dietary lapses can hinder weight loss and yoga can improve self-regulation, which may protect against lapses. This study examined the effect of yoga on dietary lapses, potential lapse triggers (e.g., affective states, cravings, dietary temptations), and reasons for initiating eating following weight loss treatment. Methods: Sixty women with overweight/obesity (34.3 ± 3.9 kg/m2) were randomized to a 12 week yoga intervention (2x/week; YOGA) or contact-matched control (cooking/nutrition classes; CON) following a 12-week behavioral weight loss program. Participants responded to smartphone surveys (5x/day) over a 10-day period at baseline, 12, and 24 weeks to assess lapses and triggers. Results: At 24 weeks, YOGA and CON differed on several types of lapses (i.e., less eating past full, eating more than usual, loss of control when eating, self-identified overeating, difficulty stopping eating in YOGA), and YOGA was less likely to eat to feel better or in response to stress (ps < 0.05). YOGA also reported less stress and anxiety and more positive affect (ps < 0.01); dietary temptations and cravings did not differ from CON. Conclusion: Yoga resulted in fewer dietary lapses and improved affect among women with overweight/obesity following weight loss. While preliminary, findings suggest that yoga should be considered as a potential component of weight loss treatment to target dietary lapses.

Exploring Factors Associated with Dietary Improvement Among Participants Who Completed a Randomized Controlled Trial for Physical Activity: Evidence of a Transfer Effect.

BACKGROUND: This research aimed at understanding how changes in one behavior affect other behaviors, known as "transfer effect," could extend knowledge of shared constructs among compound health risk behaviors, and improve methods for promoting simultaneous behavior changes. The current study explored whether participants who completed a randomized controlled trial for physical activity (PA) improved their diet with no intervention in diet or nutrition. METHODS: US adults (N = 283) were randomly assigned to 12 weeks of either exercise videogames, standard exercise, or an attention control. Secondary analyses were conducted to examine a possible transfer effect of the intervention on diet at end of intervention (EOT) and 6-month follow-up. Assessments of potential PA constructs (i.e., exercise enjoyment, self-efficacy) and demographics (e.g., age, gender) were conducted. PA, specifically moderate-to-vigorous levels of physical activity (MVPA), was measured using a self-report measure. Diet was measured using the Rate Your Plate dietary assessment. RESULTS: Findings support that a randomization effect was associated with a higher likelihood of increasing MVPA (ß = 30.00, 95% CI = 4.46, 64.46) and dietary improvement at EOT (ß = 1.48, SE = .83, P = .01) and follow-up (ß = 1.74, SE = .52, P = .02). At EOT, changes in diet were associated with higher PA enjoyment (ß = 0.41, SE = 0.15, P = .01). This intervention effect on diet was moderated by gender, with women showing more dietary improvement than men (ß = - .78, SE = 13, P = .03). At 6 months, dietary improvement was associated with greater self-efficacy (ß = .04, SE = .01, P = .01). CONCLUSION: This study shows evidence of a transfer effect among two synergistic behaviors and expands understanding of factors that predict the occurrence of this type of behavior change.

Greater engagement in valued activities is associated with less barriers to quitting smoking among smokers with mobility impairments.

BACKGROUND: Individuals with mobility impairments (MI; use equipment to ambulate) have a high prevalence of both smoking and depression. Behavioral activation (BA) purports that depressed mood is remediated through valued activity engagement and may facilitate smoking cessation in MI populations. OBJECTIVE: We examined cross-sectional associations between activity engagement and variables important for smoking cessation among a high-risk group of smokers (people with MIs) and also describe a smoking cessation intervention based on BA, given the lack of studies on smokers with MIs. METHODS: This study used data from a smoking cessation trial enrolling smokers with MIs (n = 263). We assessed valued activities, activity type, activity restriction due to MI, and replacement of restricted activities. Motivation and confidence to quit smoking, number of cigarettes per day, and mood were also assessed. Analysis was performed with generalized linear (or logistic) regression models adjusted for age and physical functioning using aggregated data at baseline. RESULTS: Greater number and frequency of valued activities was associated with less smoking, depression, negative affect, and stress and higher positive affect and self-efficacy to quit. Activity restriction was associated with greater odds of major depression, and activity replacement with lower odds of major depression, lower stress, and higher positive affect and self-efficacy. Strength of associations varied by activity type. CONCLUSIONS: Consistent with our theoretical model, BA activity constructs were associated with several mediators of smoking outcomes in the expected directions. Smokers engaging in valued activities have more favorable profiles for smoking cessation and mood management.

Integrated smoking cessation and mood management following acute coronary syndrome: Protocol for the post-acute cardiac event smoking (PACES) trial.

BACKGROUND: Approximately 400,000 people who smoke cigarettes survive Acute Coronary Syndrome (ACS; unstable angina, ST and non-ST elevation myocardial infarction) each year in the US. Continued smoking following ACS is an independent predictor of mortality. Depressed mood post-ACS is also predictive of mortality, and smokers with depressed mood are less likely to abstain from smoking following an ACS. A single, integrated treatment targeting depressed mood and smoking could be effective in reducing post-ACS mortality. METHOD/DESIGN: The overall aim of the current study is to conduct a fully powered efficacy trial enrolling 324 smokers with ACS and randomizing them to 12 weeks of an integrated smoking cessation and mood management treatment [Behavioral Activation Treatment for Cardiac Smokers (BAT-CS)] or control (smoking cessation and general health education). Both groups will be offered 8 weeks of the nicotine patch if medically cleared. Counseling in both arms will be provided by tobacco treatment specialists. Follow-up assessments will be conducted at end-of-treatment (12-weeks) and 6, 9, and 12 months after hospital discharge. We will track major adverse cardiac events and all-cause mortality for 36 months post-discharge. Primary outcomes are depressed mood and biochemically validated 7-day point prevalence abstinence from smoking over 12 months. DISCUSSION: Results of this study will inform smoking cessation treatments post-ACS and provide unique data on the impact of depressed mood on success of post-ACS health behavior change attempts.

Biological and psychological predictors of heart rate patterns during physical activity.

Objective: Latent class modeling (LCM) offers a promising approach for examining correlates of heart rate (HR) patterns over multiple exercise sessions. This research examined biological and psychological variables associated with different patterns of HR response to physical activity (PA). Methods: In a three-arm randomized controlled trial (exercise video games vs. standard exercise vs. non-exercise control), HR was recorded during PA sessions over a 12-week period. LCM identified three patterns of HR during PA across 189 participants in active arms: 1) high HR across sessions with low variability within sessions, 2) linear increase in HR across sessions with low variability within sessions, and 3) high variability in HR across all sessions. Associations with biological (resting heart rate, blood pressure, BMI, age, cholesterol, triglycerides, HbA1c) and psychological (depression, motivations for PA, PA-induced feelings) predictors of latent class membership were iteratively tested. Results: Psychological variables played as important a role in the final model as biological variables for predicting latent class membership. Few differences were found between LC1 and LC2, but LC3 differed from the other two groups in that participants were likelier to report that feel revitalized after PA (vs. LC1 and LC2), to be less motivated for PA (vs. LC1), reported greater depression (vs. LC1 and LC2), and were younger (vs. LC1). Conclusions: These findings demonstrate the potential of LCM to identify biological and psychological factors associated with chronotropic responses to PA, and advance understanding of the role of psychological factors in chronotropic PA outcomes.

Modeling Health Event Impact on Smoking Cessation.

Background: This study examined how cognitive and affective constructs related to an acute health event predict smoking relapse following an acute cardiac health event. Methods: Participants were recruited from emergency departments and completed cognitive and emotional measures at enrollment and ecological momentary assessments (EMA) for 84 days postvisit. Results: Of 394 participants, only 35 (8.9%) remained abstinent 84 days postvisit. Time to relapse was positively associated with age, actual illness severity, self-efficacy, and quit intentions. Conclusions: Older, seriously ill patients with strong confidence and intentions to quit smoking remain abstinent longer after discharge, but most still relapse within three months.

A preliminary investigation of yoga as an intervention approach for improving long-term weight loss: A randomized trial.

OBJECTIVE: Yoga targets psychological processes which may be important for long-term weight loss (WL). This study is the first to examine the feasibility, acceptability, and preliminary efficacy of yoga within a weight management program following WL treatment. METHODS: 60 women with overweight or obesity (34.3±3.9 kg/m2, 48.1±10.1 years) were randomized to receive a 12-week yoga intervention (2x/week; YOGA) or a structurally equivalent control (cooking/nutrition classes; CON), following a 3-month behavioral WL program. Feasibility (attendance, adherence, retention) and acceptability (program satisfaction ratings) were assessed. Treatment groups were compared on weight change, mindfulness, distress tolerance, stress, affect, and self-compassion at 6 months. Initial WL (3-mo WL) was evaluated as a potential moderator. RESULTS: Attendance, retention, and program satisfaction ratings of yoga were high. Treatment groups did not differ on WL or psychological constructs (with exception of one mindfulness subscale) at 6 months. However, among those with high initial WL (≥5%), YOGA lost significantly more weight (-9.0kg vs. -6.7kg) at 6 months and resulted in greater distress tolerance, mindfulness, and self-compassion and lower negative affect, compared to CON. CONCLUSIONS: Study findings provide preliminary support for yoga as a potential strategy for improving long-term WL among those losing ≥5% in standard behavioral treatment.

Feasibility and Acceptability of a Smoking Cessation Program for Individuals Released From an Urban, Pretrial Jail: A Pilot Randomized Clinical Trial.

Importance: Tobacco use prevalence among individuals involved in the criminal-legal system is 125% higher than that of the general population and leads to high levels of smoking-related morbidity and mortality. Objective: To examine the acceptability, feasibility, and preliminary clinical outcomes of a smoking cessation intervention for individuals who are incarcerated. Design, Setting, and Participants: This pilot randomized clinical trial was conducted from January 2019 to May 2020. Participants were recruited in a pretrial county jail in a large Midwestern US city and were followed up after release. Participants were incarcerated, smoked daily before incarceration, desired to stay quit or reduce cigarette smoking upon release, and expected to be released to the community within 90 days of enrollment. Data analysis was performed from June to October 2020. Interventions: Participants randomized to the counseling plus nicotine replacement therapy (NRT) group received 1 hour of smoking cessation counseling in jail, a supply of nicotine lozenges upon release, and up to 4 telephone counseling sessions after release. Those randomized to brief health education (BHE) received 30 minutes of general health education in jail. Main Outcomes and Measures: The primary clinical outcome was biologically verified 7-day point prevalence abstinence (PPA) at 3 weeks after release. Secondary clinical outcomes included 7-day PPA at 12 weeks, changes in number of cigarettes per day, and time to smoking lapse and relapse. Results: A total of 46 participants (42 men [91%]; mean [SD] age, 38.2 [9.1] years) were enrolled and remained eligible at release; 23 were randomized to the counseling plus NRT group and 23 were randomized to the BHE group. Recruitment, enrollment, and retention of participants was feasible and acceptable. There were no significant differences in smoking abstinence between groups as determined by 7-day PPA at 3 weeks (adjusted 7-day PPA, 11.9% for counseling plus NRT vs 10.6% for BHE; odds ratio, 1.13; 95% CI, 0.14-9.07) and at 12 weeks (adjusted 7-day PPA, 11.1% for counseling plus NRT vs 14.3% for BHE; odds ratio, 0.75; 95% CI, 0.09-6.11). Cigarettes per day for the counseling plus NRT group decreased more compared with the BHE group at both 3 weeks (difference [SE], -4.58 [1.58] cigarettes per day; 95% CI, -7.67 to -1.48 cigarettes per day; P = .007) and 12 weeks (difference [SE], -3.26 [1.58] cigarettes per day; 95% CI, -5.20 to -0.20 cigarettes per day; P = .04) after release. Conclusions and Relevance: Initiation of counseling plus NRT during incarceration and continuing after release is feasible and acceptable to participants and may be associated with reduced cigarette use after release. However, additional supports are needed to increase engagement in telephone counseling after release. A larger clinical trial is warranted to determine the effectiveness of counseling plus NRT.

A qualitative examination of drinking patterns among community college students.

Objective: The purpose of this study was to gain insight about patterns of alcohol use and related consequences among heavy drinking community college students. Participants: About 26 community college students (Mean age 22.3 years, 46% men, 69% White) participated in this study between January and April 2013. Methods: Five qualitative focus group discussions were conducted during formative research preceding a text message intervention; participants were asked about common drinking behavior patterns among community college students, as well as how age and gender affect drinking. Sessions were audio-recorded and transcribed verbatim. Participants also completed a brief quantitative survey about their drinking behavior and its consequences. Results: Qualitative data identified several themes: (1) reasons for drinking, (2) drinking occasions, (3) age- and experience-related differences in drinking, including patterns specific to community college students and women. Conclusion: Research is needed to develop innovative strategies to reduce alcohol harm in this understudied population.

Exercise Video Games are Associated with More Positive Affective Response, which Predicts Physical Activity Adherence.

Background: A more positive affective valence during exercise is predictive of adherence to physical activity programs. This study examines the relationship between affective response during exercise and longer-term maintenance of physical activity among individuals using exercise video games (EVGs) and standard modalities of physical activity (i.e., walking, cycling). Methods: Healthy adults (mean age 45.4, SD=14.5) were randomly assigned to a 12-week supervised, thrice weekly program of EVGs (n=93) or Standard exercise (n=96), and were assessed for affect immediately before, at the mid-point, and immediately after one exercise session per week. Participation in moderate-to-vigorous physical activity (MVPA) was conducted at end of treatment (EOT) and 6-month follow up. Results: EVG participants reported more positive affective valence during exercise compared to Standard participants (b=.63, SE=.08, p<.001), and perceived less exertion (b=.52, SE=.36, p=.04) compared to Standard participants. For both groups, a more positive affective valence during exercise was significantly predictive of continued physical activity at 6-months (b=6.64, SE=2.50, p=.01). EVG participants also showed a significant chronic effect such that week-to-week there were improvements in affect prior to exercise and this effect was significantly associated with greater MPVA at EOT and follow-up (b=21.96, SE=10.10, p=.03 at EOT). Among Standard participants no significant chronic effect was seen over time. Conclusions: EVGs may provide an effective means of promoting more positive shifts in affective valence both during, and in anticipation of, physical activity that encourages longer-term participation.

Design and rationale for a randomized trial of a theory- and technology- enhanced physical activity intervention for Latinas: The Seamos Activas II study.

INTRODUCTION: Latina women report disproportionately high rates of physical inactivity and related chronic health conditions. Physical activity (PA) efforts to date have shown modest success in this at-risk population; thus, more effective interventions are necessary to help Latinas reach national PA guidelines and reduce related health disparities. This paper describes the design, rationale, and baseline findings from the Seamos Activas II intervention. METHODS/DESIGN: The ongoing RCT will test the efficacy of the Seamos Saludables PA print intervention vs. a theory-and technology-enhanced version (Seamos Activas II). The purpose of the study is to increase the percentage of Latinas meeting the national PA guidelines compared to the prior trial, improve biomarkers related to disease, and extend generalizability to a broader and more representative population of Latinas (i.e. Mexican/Mexican-Americans). Intervention refinements included further targeting key constructs of Social Cognitive Theory, and incorporating interactive text message-based self-monitoring strategies. The primary outcome is change in minutes per week of MVPA measured by ActiGraph GT3X+ accelerometers at 6- and 12-months. Secondary PA outcomes assessed by the 7-Day PA Recall will be used to corroborate findings. RESULTS: Participants (N = 199) are Latinas 18-65 years (mean = 43.8) of predominantly Mexican origin (89%). At baseline, objectively measured MVPA was 39.51 min/week (SD = 71.20, median = 10) and self-reported MVPA was 12.47 min/week (SD = 22.54, median = 0).Participants reported generally low self-efficacy and higher cognitive vs. behavioral processes of change. CONCLUSION: Addressing interactivity and accountability through text messaging, and more rigorously targeting theoretical constructs may be key to helping Latinas achieve nationally recommended PA levels and thereby reducing health disparities.

Mediators of physical activity between standard exercise and exercise video games.

OBJECTIVE: Exercise video games (EVGs) may offer an attractive, sustainable alternative or supplement to traditional modes of exercise. Understanding the psychosocial factors that influence the appeal of EVGs is important for improving the efficacy of video games as a method of promoting the uptake and long-term maintenance of physical activity. METHODS: This study examined changes in psychosocial constructs from self-determination theory and self-efficacy theory as mediators of intervention efficacy among 189 healthy, sedentary adults randomized to 12-week programs of either EVGs or standard exercise (e.g., treadmill walking, stationary cycling) followed by 6 months of follow-up. The EVG group engaged in significantly more weekly minutes of moderate to vigorous physical activity (MVPA) at the end of treatment compared with the standard exercise group. Univariate and multivariate mediational models were used to examine theoretically derived psychosocial constructs as potential mediators of differential intervention effects. RESULTS: Univariate mediational models suggest a significant indirect effect of treatment on MVPA outcomes through enjoyment, self-efficacy, stress management, depressive symptoms, and positive engagement (p < .05). Multiple mediational analyses confirm all the univariate results (p < .05), with the exception of enjoyment. CONCLUSIONS: Differences in the efficacy of EVG versus standard exercise interventions were mediated by several psychosocial constructs, suggesting that qualities specific to game play may enhance adherence to physical activity both in and outside of the laboratory environment.

African American women's relationship with their mobile phone, and what they want in a mobile delivered physical activity intervention: guidance for intervention development.

BACKGROUND: Mobile phone text messaging is an emerging platform in physical activity (PA) interventions with African American (AA) women. Research on the relationship that AA women have with their mobile phone as well as their views about text messaging as a potentially viable platform to help them acquire and maintain regular PA is central in advancing this field of research. Both self-report measures and qualitative interviews may be helpful in this endeavor. METHODS: In the current study, a sample of 42 generally physically inactive AA women (mean age =35, SD =10.25) completed the Mobile Phone Affinity Scale (MPAS), which consists of six subscales that represent both positive (Connectedness, Productivity, Empowerment) and negative (Continuous Use, Anxious Attachment, Addiction) cognitions and behaviors that are associated with mobile phone use patterns. A subgroup of twenty participants completed a semi-structured qualitative interview that explored their views of text messaging technology as a potential platform to help become and remain physically active. Quantitative analyses included frequency and analyses of variance (ANOVAs) and assessed mobile phone use patterns and demographic differences based on age, marital status and education on the MPAS. Qualitative content analysis was conducted on participants' verbatim responses. RESULTS: Results indicated that participants overall endorsed the positive MPAS subscales at a higher frequency compared to the negative subscales. Demographic differences were noted only for age and marital status for some of the MPAS subscales. Younger participants reported higher mean scores for the MPAS subscales Connectedness (P=0.005), Empowerment/Safety (P=0.04), Continuous Use (P=0.04), and Addiction (P=0.004) in comparison to older participants. Significant results for marital status showed single participants were higher on the Connectedness (P=0.02) and Productivity (P=0.01) subscales compared to married participants. Qualitative data showed that 19 of the 20 participants (95%) viewed text messaging as an appealing platform to deliver daily motivational messages to increase PA engagement. Participants stated a text messaging PA intervention would be "convenient" and "motivating". However, most participants suggested that other mobile phone technology applications in addition to text messaging would facilitate self-monitoring PA behaviors (e.g., goal setting, activity tracking) in mobile phone delivered (mHealth) PA interventions targeting AA women. CONCLUSIONS: The study findings provide guidance in the development of mHealth intervention approaches for PA promotion that are likely to appeal to AA women, increase engagement, and behavior change among this group.

Reduction in HbA1c with Exercise videogames among participants with elevated HbA1c: Secondary analysis of the Wii Heart Fitness trial.

AIMS: Physical activity plays an important role in blood glucose management, yet most adults with elevated blood glucose do not engage in regular physical activity. Exercise videogames (EVGs) may be an attractive alternative for persons who have not found standard exercise modalities appealing. METHODS: This sub-study within a larger trial examined the effects of 12 weeks of EVGs versus standard exercise (e.g., treadmill, cycling) and a control condition among individuals with elevated HbA1c (100% prediabetic). This study was conducted at a university research lab. Outcomes included HbA1c and weekly minutes of moderate to vigorous physical activity (MVPA) assessed using self-report and accelerometer.Other health risk indices (e.g., lipids) and psychosocial constructs shown to influence exercise participation (e.g., intrinsic motivation) were assessed. RESULTS: Participants (n = 84), averaged age 51.4 years (range 20-79), 80% were female, and 77.4% were non-Hispanic. Baseline HbA1c ranged from 5.7% to 6.4% (39-49 mmol/mol). At week 12, EVG participants demonstrated an average 2% reduction in HbA1c compared to a 0.6% reduction in Standard and Control groups (p's = 0.04 and 0.03). EVG participants engaged in significantly more MVPA than Standard (+17 min/week) and Controls (+54 min/week) (p's < 0.05), had reduced LDL cholesterol (p = 0.05) and trends suggesting reduced body fat (p = 0.10). EVG participants reported higher exercise enjoyment and motivation compared to other participants. CONCLUSIONS: EVGs may be an attractive and effective tool to improve management of blood glucose that might contribute toward preventing the onset of type 2 diabetes among those with prediabetes.

A text message delivered smoking cessation intervention: Design and rationale of the Text My Quit Study.

INTRODUCTION: Smoking cessation interventions delivered through mobile technologies offer promise as an effective intervention tool. However, most existing programs have not been empirically tested, were not developed with end-user participation, and/or do not address evidence-based cognitive and behavioral variables shown to enhance smoking cessation in clinical trials. In addition, many programs tested in research trials have required users to access the internet and/or a smartphone app to access all program features, limiting the potential reach of those programs. METHODS/DESIGN: This study is a randomized controlled trial testing the efficacy of the TMQ intervention for smoking cessation. All participants are randomly assigned to receive 12 weeks of either; (1) a tailored smoking-cessation intervention delivered 100% through text messaging (TMQ), or (2) non-smoking-related text messages serving as a control for contact and subject burden (Mojo). Assessments are conducted at baseline, 3- and 6-month follow-up. The primary outcome is prolonged abstinence using an intent-to-treat approach. To understand why TMQ may be more effective than Mojo, we will test several posited mechanisms of action (i.e., mediators) that may underlie intervention efficacy and will examine use of the TMQ integrated social support (ISS) network. At the end of treatment, semi-structured interviews will be conducted with TMQ participants. CONCLUSIONS: This study will provide a rigorous test of an innovative smoking cessation program delivered 100% through text messages. Use of mixed methodologies will provide the opportunity to enhance our understanding of the user's experience with TMQ and identify areas for future enhancement and/or expansion.

Exercise Videogames, Physical Activity, and Health: Wii Heart Fitness: A Randomized Clinical Trial.

INTRODUCTION: Adults who engage in regular physical activity have lower rates of morbidity and mortality than those who do not. Exercise videogames may offer an attractive, sustainable alternative or supplement to traditional modes of exercise. This study compared exercise videogames with standard exercise modalities for improving uptake and maintenance of moderate to vigorous physical activity, and health risk indices. STUDY DESIGN: A three-arm clinical RCT including 12 weeks of supervised laboratory-based moderate to vigorous physical activity followed by 6 months follow-up. SETTING/PARTICIPANTS: This study was conducted at a university affiliated hospital research lab. Healthy, sedentary adults were eligible. INTERVENTIONS: This study compared a 12-week program of supervised exercise videogames versus standard exercise (e.g., treadmill) versus control. Data were collected from January 2012 to September 2017 and analyzed in 2018. MAIN OUTCOME MEASURES: The primary outcome was weekly minutes of moderate to vigorous physical activity at end of treatment, assessed at 3 and 6 months post-intervention by using self-report and accelerometer data. Health risk indices (e.g., HbA1c, lipids) were also assessed. RESULTS: Participants (N=283) had an average age of 46.2 ±13.5 years; 79% were female. At end of treatment, those in the exercise videogame arm engaged in 30 minutes/week more moderate to vigorous physical activity compared with standard exercise and 85 more minutes/week than controls (all p<0.05). Exercise videogame participants had greater reductions in cholesterol, HbA1c, and body fat versus other groups. Reductions in cholesterol were twice as large in exercise videogame versus standard participants. CONCLUSIONS: Exercise videogames produced greater uptake and maintenance of moderate to vigorous physical activity compared with standard exercise and improvements in multiple health risk indices. Exercise videogames may promote sustainable physical activity with significant health benefits. TRIAL REGISTRATION: This study is registered at www.clinicaltrials.gov NCT03298919.
