Purpose: To explore the theoretical constructs that functioned as mediators of interventions for moderate-to-vigorous physical activity (MVPA) maintenance among breast cancer survivors. Method: 161 survivors were randomized into 3 groups: Reach Plus, Reach Plus Message or Reach Plus Phone. All participants received a 3-month theory-based intervention delivered by volunteer coaches. During months 4-9, all participants monitored their MVPA and received feedback reports. Additionally, Reach Plus Message received weekly text/email messages and Reach Plus Phone received monthly calls from their coaches. Assessments of weekly MVPA minutes and theoretical constructs (self-efficacy, social support, physical activity [PA] enjoyment and PA barriers) were obtained at baseline, 3, 6, 9 and 12-months. Analyses: Using a multiple mediator analysis with a product of coefficients approach, we examined mechanisms associated with between-group differences over time in weekly MVPA minutes. Results: Self-efficacy mediated effects of Reach Plus Message vs. Reach Plus at 6 (ab = 16.99) and 9 M (ab = 27.45); social support mediated effects at 6 (ab = 4.86), 9 (ab = 14.30) and 12 M (ab = 6.18). Self-efficacy mediated effects of Reach Plus Phone vs. Reach Plus at 6 (ab = 18.76), 9 (ab = 28.93) and 12 M (ab = 18.18). Social support mediated effects of Reach Plus Phone vs. Reach Plus Message at 6 (ab=-5.50) and 9 M (ab=-13.20); PA enjoyment mediated effects at 12 M (ab=-3.63). Conclusions: PA maintenance efforts should focus on strengthening breast cancer survivors' self-efficacy and obtaining social support.

Latinas report disproportionately low physical activity (PA) levels and related health conditions. Reducing chronic disease in Latinas requires interventions to increase and maintain health-enhancing PA levels; yet limited intervention studies have examined PA maintenance among Latinas. The present study evaluated the efficacy during the maintenance phase (months 6-12) of the Enhanced PA intervention for Latina adults in Seamos Activas II compared to the Original PA Intervention. Seamos Activas II was conducted in San Diego, California from 2015 to 2020. Underactive adult Latina women (N = 199), mainly of Mexican descent (89%) were randomized to the original intervention or a theory- and technology-enhanced intervention. Their PA was measured objectively (via accelerometers) and via self-report at baseline, 6, and 12 months. Quantile regression models assessed treatment effects on min/week of moderate to vigorous PA (MVPA) at 12 months. Generalized linear models examined treatment effects on indicators of meeting 2008 National PA Guidelines. Both groups maintained the significant gains in MVPA they had made during the first 6 months of the intervention, neither increasing nor decreasing their MVPA over the maintenance period, with no significant between-group differences. At 12 months, 46.3% of Enhanced Intervention participants were meeting self-reported PA guidelines (vs 35.6 % of the Original PA Intervention arm, p = .02). Even with minimal contact throughout the maintenance phase, participants maintained their MVPA, which underscores the importance of continued use of evidence-based behavior change tools and techniques to reinforce newly established habits. Theoretical and technological enhancements may help Latinas to continue meeting PA guidelines during maintenance periods.

Background: Few cessation studies have examined their recruitment methods to determine the most effective methods for enrollment and retention. Purpose: Data from a randomized controlled trial of yoga for smoking cessation was used to evaluate recruitment methods (e.g., radio, referral) and their relationship to enrollment, participant characteristics, and retention at end of treatment (EOT). Methods: Screening data from 1065 adults were analyzed for recruitment method, eligibility, randomization, and retention through EOT using Analysis of Variance and Chi-squared tests. Costs per enrolled participant were calculated. Results: Rates of participant accrual from screening through randomization differed by recruitment method (p < 0.05), although there were no differences in retention post-randomization. Among randomized participants, the majority were recruited via radio (44%) and the least number via newspaper (5%). There were differences in baseline psychosocial (i.e., nicotine dependence, readiness to quit) and demographic (i.e., age, employment) characteristics of randomized participants (n = 227, 55.5% women) across recruitment methods. Differences in costs between recruitment methods (p < 0.001) were noted. Discussion: Recruitment methods differed substantially in their cost and ability to attract individuals who would ultimately enroll. Translation to Health Education Practice: This investigation highlights the need to combine different recruitment methods to attract diverse individuals into cessation treatments.

IntroductionLatino men experience disproportionately high rates of diseases related to low physical activity, yet they are poorly represented in physical activity intervention trials. Efforts to promote physical activity in Latina women show promising results, yet such interventions are yet to be extended to Latino men. This study tested a computer expert system‒tailored, text messaging-supported physical activity intervention for underactive Spanish-speaking Latino men compared with a control group matched for contact time. Potential predictors of intervention success were also explored.Study designRandomized trial. Participants were randomized to receive a Tailored Physical Activity Intervention (Intervention) or a Wellness Control (Control). Data were collected in 2015-2017 and analyzed in 2018-2019.Setting/participantsInsufficiently active Latino men (n=46).InterventionIntervention participants received a baseline counseling session and then, individually tailored print materials and text messages on a tapered schedule for 6 months. Control participants received printed wellness materials and text messages on the same schedule.Main outcome measuresPrimary outcome was a change in weekly moderate to vigorous physical activity from baseline to 6 months measured by accelerometers. Self-reported moderate to vigorous physical activity measured by the 7-day Physical Activity Recall Interview was a secondary outcome.ResultsFor Intervention participants, median accelerometer-measured moderate to vigorous physical activity increased from 10.0 minutes/week at baseline to 57.5 minutes/week at 6 months, whereas for Control participants, it increased from 21.0 minutes/week at baseline to 23.0 minutes/week at 6 months (p

Background and Aims Design Setting and Participants Measurements Findings Conclusions Numerous studies have demonstrated that alcohol preceded and increased the odds of intimate partner violence (IPV). These prior studies were restricted to one dyad member despite theory suggesting that acute alcohol use by both partners should increase the risk for IPV to a greater degree than when only one partner drinks. We hypothesized that alcohol use by both dyad members, relative to one or no dyad members, would proximally precede and increase the odds of IPV perpetration and victimization.A 60‐day daily diary design was used, where both dyad members of dating couples completed independent reports on IPV perpetration/victimization and alcohol use via a secure survey website.Alcohol using college‐student couples, aged 18–25 (n = 181 couples), from a Midwestern university in the United States participated. A convenience sample strategy was used.Daily surveys asked about alcohol use and IPV perpetration and victimization the prior day, including whether alcohol use preceded or followed IPV. The primary outcome was psychological IPV; secondary outcomes were physical and sexual IPV.Longitudinal random effects models suggested statistically significant associations between drinking behavior and IPV outcomes. The odds of psychological IPV perpetration were higher when both partners were drinking relative to one partner drinking [adjusted odds ratio (aOR) = 1.13, 95% confidence interval (CI) = 1.06–1.99]. Exploratory analyses showed some indication that the odds of physical IPV victimization were higher when both partners were drinking relative to one partner drinking (aOR = 2.09, 95% CI = 1.71–4.21).The risk for intimate partner violence appears to be greater when both partners drink, relative to one partner or neither partner.

Spanish-speaking Latinas have some of the lowest rates of meeting physical activity guidelines in the U.S. and are at high risk for many related chronic diseases. The purpose of the current study was to examine the maintenance of a culturally and individually-tailored Internet-based physical activity intervention for Spanish-speaking Latinas. Inactive Latinas (N  =  205) were randomly assigned to a 6-month Tailored Physical Activity Internet Intervention or a Wellness Contact Control Internet Group, with a 6-month follow-up. Maintenance was measured by assessing group differences in minutes per week of self-reported and accelerometer measured moderate to vigorous physical activity (MVPA) at 12 months after baseline and changes in MVPA between the end of the active intervention (month 6) and the end of the study (month 12). Potential moderators of the intervention were also examined. Data were collected between 2011 and 2014, and were analyzed in 2015 at the University of California, San Diego. The Intervention Group engaged in significantly more minutes of MVPA per week than the Control Group at the end of the maintenance period for both self-reported (mean diff. = 30.68, SE = 11.27, p = .007) and accelerometer measured (mean diff. = 11.47, SE = 3.19, p = .01) MVPA. There were no significant between- or within-group changes in MVPA from month 6 to 12. Greater intervention effects were seen for those with lower BMI (BMI × intervention = -6.67, SE = 2.88, p = .02) and lower perceived places to walk to in their neighborhood (access × intervention = -43.25, SE = 19.07, p = .02), with a trend for less family support (social support × intervention = -3.49, SE = 2.05, p = .08). Acculturation, health literacy, and physical activity related psychosocial variables were not significant moderators of the intervention effect during the maintenance period. Findings from the current study support the efficacy of an Internet-delivered individually tailored intervention for maintenance of MVPA gains over time.

Background: Psychosocial predictors of breastfeeding and changes in those factors during pregnancy, along with the relationship of those changes with both breastfeeding and smoke use and exposure, are not well explored. Research Aim: The aim of this study was to identify distinct trajectories of psychosocial determinants of breastfeeding and smoking in pregnant women. Methods: We used a longitudinal study design and data from a randomized controlled trial conducted among smoke-exposed pregnant women and their infants. Participants were recruited early in pregnancy and were surveyed at ≤ 16 and 32 weeks gestation, delivery, 3 and 6 months postpartum for breastfeeding intentions, initiation, continuation, and smoke use and exposure. Psychosocial variables associated with breastfeeding were measured at baseline and 32 weeks gestation using the Mitra index, a structured questionnaire that assesses barriers and facilitators of breastfeeding intentions. Latent class growth analysis was performed using Mitra scores to identify distinct subgroups of participants with different trajectories. Sociodemographic characteristics, breastfeeding, and tobacco smoke use and exposure were compared across classes. Results: Three or four trajectories were identified for each of the six Mitra scores. Trajectories for all Mitra scores were associated with breastfeeding intention and initiation. Overall, Mitra, knowledge, self-efficacy, social support, and time barrier classes all differed by tobacco smoke use or exposure. Conclusion: Trajectories of breastfeeding knowledge, self-efficacy, social support, and time to breastfeed/social barriers are associated with tobacco smoke use and exposure during pregnancy. Encouragement to breastfeed and to cease and avoid tobacco smoke should start early in pregnancy, focusing on these determinants to improve health outcomes. [ABSTRACT FROM AUTHOR]

BackgroundInternet access has grown markedly in Latinos during the past decade. However, there have been no Internet-based physical activity interventions designed for Latinos, despite large disparities in lifestyle-related conditions, such as obesity and diabetes, particularly in Latina women. The current study tested the efficacy of a 6-month culturally adapted, individually tailored, Spanish-language Internet-based physical activity intervention.MethodsInactive Latinas (N = 205) were randomly assigned to the Tailored Physical Activity Internet Intervention or the Wellness Contact Control Internet Group. Participants in both groups received emails on a tapered schedule over 6 months to alert them to new content on the website. The primary outcome was minutes/week of moderate to vigorous physical activity (MVPA) at 6 months as measured by the 7-Day Physical Activity Recall; activity was also measured by accelerometers. Data were collected between 2011 and 2014 and analyzed in 2015 at the University of California, San Diego.ResultsIncreases in minutes/week of MVPA were significantly greater in the Intervention Group compared to the Control Group (mean difference = 50.00, SE = 9.5, p

Perceptions of the physical and social environment have been shown to be predictive of physical activity (PA) behavior. However, the mechanisms of this association have not been examined. Affective response to PA was examined as a putative mediator of the association between perceptions of the PA environment and subsequent PA behavior. As part of a PA promotion study, 59 low-active overweight or obese but otherwise healthy adults completed real-time assessments of the perceived physical and social PA environment, affective response to PA, and PA behavior over a 6-month period. As hypothesized, decreased latency to and greater duration of subsequent PA was predicted by engaging in PA with a partner (b = 17.24, SE = .45, p < .01), engaging in PA outdoors versus indoors (b = 3.70, SE = 0.67, p < .01), and perceived pleasantness of the physical (b = 0.59, SE = .17, p < .01) and social settings (b = 0.68, SE = .16, p < .01). Affective response to PA (a shift toward feeling good versus bad during PA) mediated the association between engaging in PA with a partner (a path: 0.53(.11), p < .01, b path: 0.42(.12), p < .01, ab path: 0.22(.08), 95% CI .09-.41) and perceived pleasantness of the physical (a path: .38(.02), p < .01; b path: .65(.23), p = .01; ab path: .25(.09), 95% CI .08-.43) and social setting (a path: .35(.02), p < .01; b path: .57(.23), p = .01; ab path: .20(.08), 95% CI .03-.37) and PA behavior, but not the association between engaging in PA outdoors versus indoors and PA behavior.

The purpose of this study is to explore the mediators associated with physical activity (PA) within the adoption and maintenance phase of a PA intervention trial among breast cancer survivors. Overall, 192 breast cancer survivors (average age = 55.9 years) were randomized to an Intervention or Control group. Both groups received 8 calls in the first 3-months, 3 monthly calls, and then entered a no-contact maintenance phase for the remaining 6-months. Assessments were completed at baseline, 3-months, 6-months and 12-months. On average, participants were 55.9 years of age (SD = 9.8) and 2.9 years since diagnosis (SD = 2.2). In the adoption phase, all significant univariate mediators (self-efficacy, cognitive and behavioral processes and decisional balance cons) were included in the multivariate model. Results suggest self-efficacy (ab = 13.56, SE = 7.04) and behavioral processes (ab = 36.10, SE = 12.22) were significant for PA adoption. No mediators were identified in the maintenance phase. In the adoption phase, there were significant indirect effects of group on PA adoption through self-efficacy and behavioral processes. There were no indirect effects of group on PA maintenance., Author(s): Madison M. Kindred [sup.1] , Bernardine M. Pinto [sup.1] , Shira I.

Internet-based interventions show promise as an effective channel for promoting physical activity. However, a paucity of research has been conducted among underserved groups despite recent increases in Internet access and physical activity-related health disparities in these communities. Thus, the current randomized controlled trial will test the efficacy of an individually tailored, Internet-based physical activity intervention for Latinas. This program was culturally and linguistically adapted for the target population through extensive formative research. Two hundred eighteen sedentary Latinas were randomly assigned to the Tailored Physical Activity Internet Intervention or the Wellness Contact Control Internet Group. The Physical Activity Internet Intervention, based on Social Cognitive Theory and the Transtheoretical Model, utilizes a website with features including self-monitoring, goal setting, discussion forum, links to online resources, individually tailored and motivation-matched physical activity feedback reports, and exercise tip sheets. Participants receive regular emails over the first 6months with a tapered dose during the second 6months (maintenance phase) to alert them to new content on the website. The main outcome is differences in minutes/week of moderate to vigorous physical activity at six months as measured by the 7-Day Physical Activity Recall and accelerometer data. High reach, low cost, culturally relevant Internet-based interventions that encourage physical activity among Latinas could help reduce health disparities and thus have a substantial positive impact on public health.

High rates of obesity in Latinas highlight the need to determine if physical activity interventions are equally effective across the body mass index (BMI) range. Thus, this study assessed how BMI impacts success of Spanish-speaking Latinas in a culturally and linguistically adapted theory-based physical activity intervention (N = 45). Longitudinal regression models tested the relationship between baseline BMI and outcomes. Overall, a trend for a negative association was found between baseline BMI and self-reported physical activity and theoretical constructs targeted by the intervention over time. For example, someone with a 25 kg/m(2) BMI would report, on average, 27.5 more minutes/week of activity compared to someone with a 30 kg/m(2) BMI at followup. Furthermore, higher baseline BMI was significantly associated with lower self-efficacy, behavioral and cognitive processes of change, and family social support over time. These findings suggest that participants with higher BMI may need additional intervention to promote physical activity.

Background: Latinas have high rates of sedentary behavior and related health disparities, but it is unknown if interventions to increase physical activity will also reduce sedentary time. The current study examined changes in objectively measured sedentary time among Latinas in a randomized controlled trial of a physical activity intervention. Methods: Spanish-speaking Latinas (N = 202) were randomized to an exercise or wellness group and wore an accelerometer at baseline, 6 months, and 12 months. Results: Participants were sedentary on an average of 8.86 hours per day (SD = 2.60) at baseline. The intervention group had significantly greater increases in sedentary time compared with the control group, with the intervention group engaging in 146 more minutes per week of sedentary time at 6 months and 254 minutes per week of sedentary time at 12 months than the control group (P = .02). The intervention effect on sedentary behavior remained after controlling for moderate to vigorous physical activity. Additionally, time spent in moderate to vigorous physical activity was positively associated with more sedentary time (P = .04). Conclusion: An intervention to increase moderate to vigorous physical activity resulted in greater sedentary time, raising concerns regarding compensation and highlighting the need for interventions to address both physical activity and sedentary behavior to improve public health.

Depressive symptoms and fatigue are prevalent among people living with human immunodeficiency virus. Resistance exercise is known to stimulate a positive affective response. Objective: To examine the acute psychological effects of resistance-exercise intensity among Black/African-American people living with human immunodeficiency virus and experiencing depressive symptoms. Methods: A total of 42 participants were randomized into a moderate- (n = 21) or high-intensity (n = 21) group. Assessments were collected before exercise (PRE), at the midpoint (MID), immediately following (POST) exercise, and 15 (DELAY 15) and 30 (DELAY 30) min after. Results: In the moderate-intensity group, affect improved PRE to POST, PRE to DELAY 15 and DELAY 30, and perceived distress decreased from PRE to all time points. In the high-intensity group, affect declined PRE to MID, and perceived distress decreased PRE to DELAY 15 and DELAY 30. Perceived activation increased PRE to MID, and POST in both groups (ps <.01). Conclusions: The moderate-intensity group compared with the high-intensity group is more effective at improving affect and energy and at reducing distress. [ABSTRACT FROM AUTHOR]
