A multiple technology-based physical activity intervention for Latina adolescents in the USA: randomized controlled trial study protocol for Chicas Fuertes. Trials 2022; 23:176. [PMID: 35197106 PMCID: PMC8864594 DOI: 10.1186/s13063-022-06105-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Accepted: 02/12/2022] [Indexed: 12/02/2022] Open
Abstract
Background Latina adolescents in the USA report some of the lowest rates of physical activity of any demographic subgroup; this is paralleled by a markedly higher lifetime risk of obesity, type 2 diabetes, and other conditions related to inactivity. Despite this, to date, no fully powered clinical trials have tested physical activity interventions specifically for this population. High use of mobile technologies (including text messages, smartphone apps, and social media) suggests this could be an appropriate intervention channel, while also having potential for broad reach. This paper describes the protocol for Chicas Fuertes, a fully powered randomized trial of a mobile technology-based physical activity intervention for Latina adolescents. Methods We plan to recruit 200 Latina teens (age 13–18) in San Diego, CA, currently engaging in ≤ 150 min/week of moderate-to-vigorous physical activity (MVPA) to be assigned 1:1 to the intervention or control groups. Those randomly assigned to the intervention group receive a one-on-one goal setting session followed by 6 months of mobile technology-based intervention, including a personalized website, Fitbit activity tracker and app, individually tailored text messages based on Fitbit data, and daily intervention content on Instagram. Those randomized to the control group receive only a Fitbit activity tracker. The main outcome is change in weekly minutes of MVPA from baseline to 6 months, measured both objectively (ActiGraph accelerometers and Fitbit Inspire HR) and subjectively (7-Day Physical Activity Recall Interview). Additional outcomes are maintenance of activity change at 12 months and changes in psychosocial constructs, including social support and self-efficacy, engagement with mobile technology channels, and costs of intervention delivery. We are also examining the potential mediators and moderators of the intervention. The efficacy of the intervention is analyzed using a mixed effects regression model, adjusting for any potential confounders not balanced by randomization. All analyses of accelerometer measured MVPA are also adjusted for wear time. Discussion The Chicas Fuertes trial uses widely available mobile technologies to target critical health behavior, physical activity, in Latina teens, a population with a high lifetime risk of lifestyle-related diseases. The results will speak to the efficacy and acceptability of the intervention, which has the potential for broad dissemination. Trial registration ClinicalTrials.govNCT04190225.

Abstract
BACKGROUND Approximately 13-19% of postpartum women experience postpartum depression and a majority report at least some stress during the postpartum phase. Traditional interventions such as psychotherapy and antidepressant medications are often not feasible or desirable. The purpose of this study was to examine two low cost, brief, accessible interventions designed to prevent postpartum depression and perceived stress among women at high risk. METHODS Participants (n = 450) who were on average four weeks postpartum, had a history of depression before pregnancy, and exercised less than 60 min per week were randomly assigned to one of the following three conditions: (1) 6-month telephone-based exercise intervention; (2) 6-month telephone-based wellness/support intervention (e.g., healthy eating, sleep, and perceived stress); or (3) usual care. RESULTS Overall, 2.4% of participants met criteria for depression at 6 months and 3.6% at 9 months with no differences between groups. At 6 months following randomization, median symptoms of depression were significantly lower among wellness participants compared to usual care participants (b = - 1.00, SE = 0.46, p = .03). Perceived stress at 6 months post-randomization was significantly lower among exercise vs. usual care participants (b = - 2.00, SE = .98, p = .04) and exercise vs. wellness participants (b = - 2.20, SE = 1.11, p = .04). CONCLUSIONS The wellness intervention was efficacious for preventing symptoms of depression; however, postpartum depression that met the diagnostic criteria was surprisingly low in all conditions among this at risk sample of postpartum women. Exercise interventions may have a protective effect on perceived stress among women at risk for postpartum depression. Practitioners should consider integrating exercise and wellness interventions into postpartum care. TRIAL REGISTRATION Clinical Trials Number: NCT01883479 (06/21/2013).

Abstract
PURPOSE The purpose of this study was to describe the feasibility, cost-effectiveness, and generalizability of a strategy for recruiting adolescents into research studies through social media. METHODS We designed and tested six Instagram advertisements (ads) with a combination of Instagram campaign objectives (Traffic vs. Reach) and types of placement (Story vs. Feed). The goal was to obtain remote assent and screen for a larger remote behavioral intervention study. The eligibility criteria for screening were being aged 13-17 years, residing in the United States, and English-speaking. The eligibility for the larger study was past year cybervictimization and smartphone ownership. A target sample was 80 participants, randomly assigned to a control or intervention group and followed up for 16 weeks. Recruitment rates and cost-per-enrolled participant with different advertising strategies, demographics, and retention were examined using descriptive statistics. RESULTS The six ads were run over 907.5 hours, generating 1,069,747 impressions, 2,051 click-throughs, and 663 completed screening surveys. Of 493 eligible participants, 24.4% assented to participate, 69.4% completed enrollment, and 4.8% dropped/withdrew after randomization. Average advertising costs were $52/participant; the lowest-cost strategy (Traffic campaign + Feed ad placement) was $19/enrolled participant. The study sample was largely white (81.3%), non-Hispanic (87.5%), and female (77.5%) with an average age of 15.33 years. Nearly half of the participants were identified as lesbian, gay, or bisexual. More than 96% of participants were retained at the 16-week follow-up. CONCLUSIONS Instagram can be a feasible and cost-effective way to recruit adolescents for a remote study. This method may be ideal for recruiting hard-to-reach audiences.

Abstract
BACKGROUND Between 15% and 70% of adolescents report experiencing cybervictimization. Cybervictimization is associated with multiple negative consequences, including depressed mood. Few validated, easily disseminated interventions exist to prevent cybervictimization and its consequences. With over 97% of adolescents using social media (such as YouTube, Facebook, Instagram, or Snapchat), recruiting and delivering a prevention intervention through social media and apps may improve accessibility of prevention tools for at-risk youth. OBJECTIVE This study aims to evaluate the feasibility and acceptability of and obtain preliminary outcome data on IMPACT (Intervention Media to Prevent Adolescent Cyber-Conflict Through Technology), a brief, remote app-based intervention to prevent and reduce the effect of cyberbullying. METHODS From January 30, 2020, to May 3, 2020, a national sample of 80 adolescents with a history of past-year cybervictimization was recruited through Instagram for a randomized control trial of IMPACT, a brief, remote research assistant-led intervention and a fully automated app-based program, versus enhanced web-based resources (control). Feasibility and acceptability were measured by consent, daily use, and validated surveys. Although not powered for efficacy, outcomes (victimization, bystander self-efficacy, and well-being) were measured using validated measures at 8 and 16 weeks and evaluated using a series of longitudinal mixed models. RESULTS Regarding feasibility, 24.5% (121/494) of eligible participants provided contact information; of these, 69.4% (84/121) completed full enrollment procedures. Of the participants enrolled, 45% (36/80) were randomized into the IMPACT intervention and 55% (44/80) into the enhanced web-based resources groups. All participants randomized to the intervention condition completed the remote intervention session, and 89% (77/80) of the daily prompts were answered. The retention rate was 99% (79/80) at 8 weeks and 96% (77/80) at 16 weeks for all participants. Regarding acceptability, 100% (36/36) of the intervention participants were at least moderately satisfied with IMPACT overall, and 92% (33/36) of the participants were at least moderately satisfied with the app. At both 8 and 16 weeks, well-being was significantly higher (β=1.17, SE 0.87, P=.02 at 8 weeks and β=3.24, SE 0.95, P<.001 at 16 weeks) and psychological stress was lower (β=-.66, SE 0.08, P=.04 at 8 weeks and β=-.89, SE 0.09, P<.001 at 16 weeks) among IMPACT users than among control group users. Participants in the intervention group attempted significantly more bystander interventions than those in the control group at 8 weeks (β=.82, SE 0.42; P=.02). CONCLUSIONS This remote app-based intervention for victims of cyberbullying was feasible and acceptable, increased overall well-being and bystander interventions, and decreased psychological stress. Our findings are especially noteworthy given that the trial took place during the COVID-19 pandemic. The use of Instagram to recruit adolescents can be a successful strategy for identifying and intervening with those at the highest risk of cybervictimization.

Abstract
Cigarette smoking remains the leading behavioral risk factor for chronic disease and premature mortality. This RCT tested the efficacy of moderate intensity aerobic exercise as an adjunctive smoking cessation treatment among women. Participants (N = 105; age = 42.5, SD = 11.2) received brief smoking cessation counseling and 10 weeks of nicotine replacement therapy and were randomized to 12 weeks of moderate intensity exercise (Exercise; n = 53) or 12 weeks of health education (Control; n = 52). Longitudinal models, with Generalized Estimating Equations, showed no differences between Exercise and Control in cotinine-verified 7-day point prevalence abstinence (Wald = 1.96, p = 0.10) or continuous abstinence (Wald = 1.45, p = 0.23) at 12-weeks (post-treatment) or 6-, 9-, or 12-month follow-up, controlling for differences in baseline nicotine dependence. There was no effect of exercise on smoking cessation. The present study adds to the literature suggesting null effects of exercise as a smoking cessation adjunctive treatment despite promising findings in short-term laboratory based studies.

Abstract
OBJECTIVES To examine (1) whether daily declines in physical activity (PA) level and/or in lung function (FEV1) predict an asthma exacerbation in a sample of urban children with asthma, and (2) the association between number of sleep awakenings and decline in daytime PA in this group. METHODS In this sample of urban children aged 7-9 years with persistent asthma (N = 147), objective methods assessing lung function via a handheld spirometer and moderate-to-vigorous physical activity (MVPA) via accelerometry were measured over a 4-week period during the fall and early winter of each year as part of a larger 5-year study. RESULTS In the entire sample, a significant association between PA and lung function was noted such that a greater decline in daily MVPA was associated with lower odds of exacerbation. Ethnic group differences showed that this association was also significant only among Latino children (odds ratio [OR] = 0.98; 95% confidence interval [CI]:0.97-0.99). A greater number of sleep awakenings were associated with greater declines in daily MVPA among Latinos only (p = .05). CONCLUSIONS Results suggest that declining MVPA may contribute to lower risk for an exacerbation. Reasons for declining MVPA need to be further explored in this group. Children with asthma may avoid or be fearful of engaging in PA or may face early symptoms which influence patterns of PA, and this may minimize risk for an exacerbation. Results also suggest reasons for night-time disruptions may need to be targeted in further research or interventions as they can contribute to PA avoidance in this high-risk group.

Abstract
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.

Abstract
BACKGROUND Compared to students at four-year residential colleges, Community College Students (CCS) are at greater risk for binge drinking and alcohol related risks, however few interventions have been developed specifically for the needs of CCS. METHODS AND DESIGN This study design tests the efficacy of a smartphone app (CARES) compared to an existing online alcohol education (AE) program. CCS (n = 250) will be recruited using a nationwide social media campaign and randomly assigned to either arm, stratified by sex and age (over/under 21). Eligibility screening, consent and assessments are conducted online and both interventions are accessible by smartphone. Assessments will be conducted at baseline, 4- and 8- weeks, end of treatment (12-weeks) and at 6-month follow-up. The primary outcomes are heavy episodic drinking (past 2 weeks), and alcohol related problems Confidence in refusing alcohol, use of protective behavioral strategies and expectations regarding alcohol use. Demographics including age, sex, race/ethnicity, marital and parental status and employment will be analyzed as potential covariates. DISCUSSION Community colleges serve approximately half of all US college students but frequently lack the resources to implement full-service alcohol prevention and education programs. The specific needs of CCS also differ from those of residential college students for whom most alcohol prevention programs have been developed. If proven efficacious, the CARES intervention may offer a scalable, easily disseminable program designed for the needs of community colleges and their students.

Abstract
BACKGROUND Daily decisions to exercise may be influenced by day-to-day changes in affective attitudes (AA) and instrumental attitudes (IA) toward exercise. However, the within-day association between AA, IA, and exercise behavior has received little attention. PURPOSE To examine the effects of more temporally proximal (daily) AA and IA on daily exercise behavior beyond traditionally assessed distal (at the beginning of an exercise program) AA and IA. METHODS In the context of a 3-month exercise promotion program (N = 50), distal AA and IA were assessed at baseline. Ecological momentary assessment was used to assess proximal AA, IA, and exercise each day. RESULTS Between-subject differences in distal AA (OR = 1.28, p = .03) and distal IA (OR = 1.34, p = .01) were predictive of average likelihood of exercise each day over the 3-month period. Within-subject differences in proximal AA (OR = 1.19, p = .007), but not proximal IA (OR = 1.11, p = .18), predicted exercise each day beyond the between-subjects effects of distal AA and IA. Exploratory analysis revealed an interaction, such that the within-subjects impact of proximal AA on daily exercise was most evident among individuals who held more negative distal AA at baseline (OR = 0.80, p < .0001). CONCLUSIONS Attitude type (affective versus instrumental) and temporality (distal versus proximal) are important to consider in attempts to predict and understand exercise behavior. In addition to targeting change in distal attitudes, exercise interventions should target changes in daily AA to impact exercise later in the same day.

Abstract
OBJECTIVE Prior studies identified single nucleotide polymorphisms (SNPs) associated with physical activity (PA) level in a natural environment and intervention study: rs978656-DNAPTP6, rs10887741-PAPSS2, rs7279064-C18orf2, and rs6265-BDNF. Using the four SNPs' polygenic score (PGS), we examined whether PGS moderates a life-style intervention's effect on changes in PA level and cardiorespiratory fitness (CRF). METHODS This is a secondary analysis of Look AHEAD, a multicenter randomized controlled trial designed to test the health benefits of a life-style intervention among 2675 participants with overweight/obesity and type 2 diabetes (ages, 45-76 years). Using linear mixed-effects models, level of PA (Paffenbarger PA questionnaire) and treadmill-assessed CRF were each regressed on four SNPs' PGS, study time (baseline, year 1, and year 4), intervention arm, and interactions between the three. Models adjusted for age, sex, body mass index, ancestry principal components (population stratification), and study sites, with Bonferroni corrections for multiple testing (α < .005). Effect modification by age was examined. RESULTS PGS was not predictive of change in CRF or PA level in response to intervention. In analyses without PGS by intervention by time, the relationships between PGS and PA phenotypes were modified by age (p interaction = .048 for CRF and .058 for PA), such that a 1-unit increase in PGS was associated with 24 kcal · wk-1 more in moderate-intensity PA and 0.004 MET higher CRF only among older groups (age >55 years for CRF, >60 years for PA level). CONCLUSIONS The effects of the intervention on PA and CRF were not moderated by the four SNPs. Future studies with extended SNP list should confirm the findings on effect modification by age.

Abstract
Maintenance of weight loss is hard to achieve, and novel interventions are needed to improve long-term outcomes. In this pilot randomized controlled trial, N = 188 participants received an online, 12-week weight loss intervention and N = 102 who lost ≥ 5% were then randomly assigned to a 1-day, 5-h workshop based on Acceptance and Commitment Therapy (ACT), Self-Regulation (SR), or no workshop (Control) with 3 months of limited email follow-up. Assessments were conducted at baseline, 3, 6, 12, 18, and 24 months. The primary outcome was percent weight change; secondary outcomes were weight-related experiential avoidance and health values-consistent behavior. ACT had greater overall weight loss (-7.18%, SE = 1.33) when compared to Control (-1.15%, SE = 1.50; p = .03). Post hoc analyses showed that ACT had significantly greater weight losses than Control (6.11%, β = -2.03, p = .048) among those with lower initial weight loss (5-7%), and significantly greater weight loss than SR (6.19%, β = -1.77, p = .05) among those with the highest initial weight losses (10% +). There is potential for continuing to develop ACT in a limited interventionist-contact format with modifications. This pilot study represents an innovative model for behavioral weight loss by reversing the typical treatment intensity model with the aim of providing interventionist support during a critical period after initial weight loss.

Abstract
OBJECTIVES Asthma and obesity disproportionately affect urban minority children. Avoidance of physical activity contributes to obesity, and urban children with asthma are at risk for lower levels of physical activity. We examined associations between lung function and moderate to vigorous physical activity (MVPA) and moderators of this association in a diverse sample of children with asthma. METHODS Urban children (N = 142) ages 7-9 with persistent asthma and their caregivers completed a study of asthma and physical activity. Longitudinal mixed effects models examining daily-level asthma and physical activity evaluated the association between asthma and MVPA, and the moderating effect of weight, and cultural/contextual factors on this association. RESULTS Average daily MVPA was below recommended guidelines. Differences in MVPA were found by racial/ethnic group (p = .04) and weight (p = .001). Poorer asthma status was associated with lower MVPA in Latino and Black participants (p's < .05), and in normal weight youth (p = .01). Body mass index (BMI) moderated the association between asthma and MVPA. Those with lower BMI had more optimal asthma status and higher MVPA levels, whereas associations attenuated for participants with higher BMI (p = .04). Caregivers' perceptions of neighborhood safety and fear of asthma were marginally associated with children's symptoms and MVPA: as perceptions of safety decreased and fear increased, associations between asthma and MVPA weakened (p's = .09 and .07, respectively). CONCLUSIONS Suboptimal asthma status is associated with less MVPA in urban children. Weight status and cultural/contextual factors play a role in the association and are worthy targets for future research and intervention.

Abstract
Introduction:
Sex differences have been noted in stroke and estrogen is associated with decreased platelet aggregation. The purpose of this study was to assess sex differences in the Platelet Oriented Inhibition in New TIA and Minor Ischemic Stroke (POINT) study.
Methods:
We performed a secondary analysis of the POINT study. Patients were analyzed by intention to treat group: 1) Males, standard (n=1351) aspirin; 2) Males, intervention (n=1335) clopidogrel+aspirin; 3) Females; standard (n=1098) aspirin; and 4) Females, intervention (n=1097) clopidogrel+aspirin. Groups were compared for baseline demographics via ANOVA followed by Mann Whitney U. A Cox Proportional Hazards Model was used to assess the primary safety and efficacy outcomes.
Results:
Baseline characteristics were significantly different only for race (p<.001) with white race being most represented. The primary outcome occurred in 6.4% of standard males, 6.7% of standard females, 5.1% of intervention males, and 4.8% of intervention females (p=0.12). Cox models suggest that male intervention participants had lower hazard rate compared to male standard participants (HR=0.79, CI:0.58-1.09) and female intervention participants had a lower hazard compared to male standard (HR=0.76, CI: 0.54-1.07) but this was not statistically significant. Major hemorrhage occurred in 0.4% of standard males, 0.5% of standard females, 0.8% of intervention males, and 1.1% of intervention females (p=0.11). Female intervention subjects had a significantly higher hazard rate of major hemorrhage compared to standard males (HR=2.99, CI:1.06-8.52) with no other between group differences.
Conclusion:
This study found that there were no significant sex differences in the reduction of recurrent vascular events in the POINT trial. The rate of major hemorrhage was higher in female intervention compared to male standard subjects, but there was no difference in rates between the female groups or the male intervention group. Future studies must provide a sample size with enough power to assess for sex differences to optimize care. Both males and females benefit from combination therapy but the risk of major hemorrhage must be considered.

Abstract
BACKGROUND Weight regain is common following behavioral obesity treatment and attenuates many of the benefits of initial weight loss. This paper describes a randomized controlled trial that will evaluate the efficacy of two low-contact weight loss maintenance interventions based on Acceptance and Commitment Therapy (ACT) and self-regulation (SR). Potential mechanisms of action and moderators of treatment effects will also be evaluated. METHODS Adults (anticipated N = 480) with overweight or obesity will complete an initial 3-month online weight loss program (Phase 1). Participants who achieve ≥4 kg weight loss (anticipated N = 288) will then be randomized to an ACT or SR weight loss maintenance intervention. Both interventions will entail four 2.5 h, face-to-face, group-based workshop sessions and 6 months of email contact. Assessments will be conducted at phase 1 baseline, phase 1 completion/pre-randomization, and 6, 12, 18, 24, and 30 months post-randomization. The primary outcome will be weight change for the period from randomization to 30 months. Potential process measures including ACT-based constructs (e.g., psychological acceptance, values-consistent behavior), self-weighing frequency, and motivation will be also be assessed, as will potential moderators (e.g., initial weight loss). CONCLUSIONS This study will compare the efficacy of two intervention approaches (ACT and SR) delivered in a scalable workshop format for long-term weight loss maintenance. Future research could examine efficacy and cost-effectiveness of these approaches in real world settings.

Abstract
OBJECTIVE Adherence to asthma controller medications is suboptimal among adolescents. We evaluated predictors of adherence and longitudinal patterns of medication use between 8th and 10th grade among a sample of youth of diverse race/ethnicity. METHODS Eighth graders with asthma on controller medications (N = 62; 40.0% non-Latino white; 23.7% Black; 37.3% Latino; 37.3% female) completed measures of medication beliefs, responsibility for asthma management, and family cohesion. Objective methods tracked medication use longitudinally. RESULTS Adherence declined during the high school transition, from 48.0% in eighth grade to 34.1% in tenth grade (F = 5.35, p < .01). Males had lower adherence (b = -10.11, SE = 5.37, p = .02, f2 = 0.11), as did Latino youth (b = -12.21, SE = 8.23, p = .03, f2 = 0.12). Family cohesion was associated with higher adherence (b = 4.38, SE = 1.98, p = .04, f2 = 0.06). Latent class models (LCMs) suggested a three-class model of longitudinal adherence patterns. This included low, declining adherence (Class 1 = 29%; higher proportion male, p = .02), high, sustained adherence (Class 2 = 26%, high family cohesion, p = .05, higher proportion female, p = .02), and low, sustained adherence (Class 3 = 45%; higher proportion Latino, p = .05, higher proportion male, p = .02). CONCLUSIONS Asthma medication adherence declined between 8th and 10th grade. LCMs indicated some youth have stable patterns of adherence (high or low), whereas others demonstrate declines. Gender differences were observed, and family cohesion was associated with higher, sustained adherence. Interventions building on family resources and targeting the barriers adolescents face are necessary to improve asthma management during this vulnerable period.

Abstract
Background Latino men in the United States report low physical activity (PA) levels and related health conditions (eg, diabetes and obesity). Engaging in regular PA can reduce the risk of chronic diseases and yield many health benefits; however, there is a paucity of interventions developed exclusively for Latino men. Objective To address the need for culturally relevant PA interventions, this study aims to develop and evaluate Hombres Saludables, a 6-month theory-based, tailored web- and text message-based PA intervention in Spanish for Latino men. This protocol paper describes the study design, intervention, and evaluation methods for Hombres Saludables. Methods Latino men aged 18-65 years were randomized to either the individually tailored PA internet intervention arm or the nutrition and wellness internet control arm. The PA intervention included 2 check-in phone calls; automated SMS text messages; a pedometer; a 6-month gym membership; access to a private Facebook group; and an interactive website with PA tracking, goal setting, and individually tailored PA content. The primary outcomes were feasibility, acceptability, and efficacy (minutes per week of total moderate-to-vigorous PA assessed via the ActiGraph GT3X+ accelerometer worn at the waist and 7-day physical activity recall at baseline and 6 months). Secondary outcomes examined potential moderators (eg, demographics, acculturation, and environmental variables) and mediators (eg, self-efficacy and cognitive and behavioral processes of change) of treatment effects at 6 months post randomization. Results This study was funded in September 2016. Initial institutional review board approval was received in February 2017, and focus groups and intervention development were conducted from April 2017 to January 2018. Recruitment for the clinical trial was carried out from February 2018 to July 2019. Baseline data collection was carried out from February 2018 to October 2019, with a total of 43 participants randomized. Follow-up data were collected through April 2020. Data cleaning and analysis are ongoing. Conclusions We developed and tested protocols for a highly accessible, culturally and linguistically relevant, theory-driven PA intervention for Latino men. Hombres Saludables used an innovative, interactive, web- and text message–based intervention for improving PA among Latino men, an underserved population at risk of low PA and related chronic disease. If the intervention demonstrates feasibility, acceptability, and preliminary efficacy, we will refine and evaluate it in a larger randomized control trial.

Abstract
OBJECTIVES This study sought to explore feasibility, acceptability, and preliminary effects of aerobic training (AT), mindfulness training (MT), or both (MT + AT) on cognitive function in older individuals at risk of dementia. METHOD Participants were randomized to AT, MT, both, or usual care (UC). Z-scores of attention, verbal fluency, and episodic memory for non-demented adults (ZAVEN) were computed at baseline, end of treatment (EOT), and 6 months since baseline. RESULTS Of the 36 enrolled participants (12 M, 24 F, mean age = 70.1 years), 97% were retained in the study at 6 months. At EOT, MT had higher ZAVEN scores than UC (b = .43, P =.03) and AT (b = .26, P = .10), while no differences were seen with MT + AT. A similar pattern was observed at a 6 month follow-up (all P values = .10). DISCUSSION MT may improve cognitive function in older individuals at risk of dementia. These preliminary findings need to be confirmed in a fully powered RCT.

Abstract
BACKGROUND Mechanisms by which mind-body practice may improve exercise behaviors in patients with coronary heart disease (CHD) are unknown. PURPOSE To identify predictors of exercise behaviors developed in response to a tai chi intervention. METHODS We conducted an exploratory analysis using data from a pilot study of tai chi for physically inactive patients with CHD. We used Latent Class Analysis to identify patterns of moderate to vigorous physical activity (MVPA) (accelerometry-assessed, average min/week) over the 9-month study period. Logistic regression was used to evaluate associations between MVPA patterns and changes in exercise self-efficacy (Self-efficacy for exercise scale), social support (Multidimensional Scale of Perceived Social Support), resilience (Brief Resilience Survey), and mindfulness (Five Facets of Mindfulness) at 6 months. RESULTS Data supported a 3-class model over time: 31% of participants were in class 1 (high and sustained MVPA, > 200 min/week), 21% were in class 2 (low and decreasing MVPA, < 100 > 50 min/week), and 48% in class 3 (low and stable MVPA, < 50 min/week). Higher mindfulness scores at 6 months were associated with a high and sustained MVPA pattern (b = 1.89, SE = 0.15, p = .01). Social support was inversely associated with low and decreasing MVPA (b = -0.72, SE = 0.34, p = .04). No associations were noted with the other factors. CONCLUSIONS Improvements in mindfulness were associated with a distinct high and sustained MVPA pattern. Although only hypothesis-generating, these findings suggest that improvements in mindfulness skills could be a mechanism for the possible effect of Tai Chi in the promotion of MVPA.

Abstract
This study explored whether telephone-delivered mindfulness training (MT) to promote medication adherence and reduce sexual risk behavior was feasible for and acceptable to people living with HIV. Participants (N = 42; 50% female; M age = 47.5 years) were randomized to MT or health coaching (HC). Pre- and post-intervention, and at 3-month follow-up, we assessed adherence to ART, sexual risk behavior, and hypothesized mediators; we also conducted individual interviews to obtain qualitative data. Results showed that 55% of patients assigned to MT completed ≥ 50% of the training calls compared with 86% of HC patients (p < .05). Most patients reported satisfaction with their intervention (MT = 88%, HC = 87%). Patients in MT and HC reported improvements in medication adherence, mindfulness, and sexual risk reduction as well as reductions in anxiety, depressive symptoms, perceived stress, and impulsivity over time; however, no between-groups differences were observed.

Abstract
Vaccination coverage among United States (U.S.) adults for tetanus continues to be lower than the national goals. Education has demonstrated a positive impact on vaccination coverage. However, recently there have been outbreaks of vaccine preventable conditions in areas with high college completion rates. This study assessed the relationship between education and tetanus vaccination. Data from the 2016 Behavioral Risk Factor Surveillance System (BRFSS), a self-reported annual survey for non-institutionalized adults in the US from the Centers for Disease Control, was analyzed in 2019. The outcome was up-to-date tetanus vaccination if received within the last 10 years. Education was categorized into 1) grade 11 or less, 2) grade 12/GED, 3) college 1-3 years, and 4) college 4 or more years. Bivariate analyses and multivariable logistic regression were conducted on the analytic sample (n = 417,473) using Stata 15, accounting for weighting and the complex survey design. In 2016, 59.9% of U.S. adults had up-to-date tetanus vaccination. Higher education level was associated with increased odds of up-to-date tetanus vaccination. The highest odds were for those with 4 or more years of college education [aOR = 1.31; 95% (CI: 1.26-1.35)]. Female sex, Black (non-Hispanic), unemployed, not being married, not having insurance or a personal health care provider, and above 45 years of age had lower odds of up-to-date tetanus vaccination. Targeted community specific vaccination education programs for those without tertiary education may help enhance the knowledge and thus the overall vaccination status in the U.S.

Abstract
Formative research is needed to develop effective interventions that eliminate secondhand smoke exposure (SHSe) and prevent tobacco use (TU) among children with asthma. This online study included 300 parents who smoke and had a child with asthma (ages 10-14) and evaluated their perceptions about prototypes of parent-directed and child-directed feedback intervention messages focused on reducing child SHSe and future TU; correlates of perceptions were explored. Parents rated examples of parent-directed messages on motivation and helpfulness for eliminating SHSe and promoting conversations about TU and also rated child-directed messages on acceptability and helpfulness for promoting conversations about TU. Messages differed by level of personalization, theoretical background, or message content. Parents found all parent-directed messages similarly motivating and helpful and all child-directed messages similarly acceptable and helpful for reducing child tobacco exposure. Differences in perceptions about feedback emerged based on parent gender, parent readiness to quit, smoking ban status, and the presence of additional smokers in the home. Overall, parents rated parent-directed and child-directed feedback message prototypes positively, including established and novel types of feedback. Parent-child feedback interventions may hold promise for breaking the intergenerational transmission of smoking among families with a parent who smokes and a child with asthma.
