This study examined whether police involvement in intimate partner violence (IPV) incidents is associated with victims’ socio-emotional problems, and emotional and physical toll symptoms for 1 month or longer post-victimization. Data from the 2010–2019 National Crime Victimization Survey suggest that police investigational effort, later contact with the police, suffering severe injury during victimization, and repeated victimization were positively associated with experiencing socio-emotional problems. Later contact with police and severe injury were positively associated with both emotional and physical toll symptoms, while the female sex was positively associated with emotional toll symptoms. The arrest of the abuser was negatively associated with physical toll symptoms. Findings highlight the need for policies and practices in response to IPV that consider the diverse needs of survivors of partner abuse to help reduce IPV-related trauma.

The coronavirus disease 2019 (COVID-19) pandemic created a sudden shift in the social lives of youth with important negative impacts on mental health. The current article aims to understand how the pandemic may have differentially impacted the mental health of adolescents and young adults with recent (1 year or less) and past (1 year) exposure to self-directed violence (SDV).Data were collected online from 990 youth and young adults, aged 13-23 years between November 27, 2020 and December 11, 2020.Participants who had recently been exposed to SDV reported being more impacted by the pandemic and had poorer mental health indicators. Participants with past SDV exposure who engaged in a high number of prosocial activities (e.g., talking with friends) were less likely to report depressive symptoms (β = -.13,Findings highlight that the effects of the COVID-19 pandemic on the mental health of young people are compounded by exposure to mental health concerns of people in their network.

Background: Only 17% of Latinas meet national physical activity (PA) guidelines for both moderate-to-vigorous aerobic and muscle-strengthening PA. Additional health benefits are derived from the combination of aerobic and muscle-strengthening PA (vs. aerobic alone), yet there is paucity in research on muscle-strengthening activity in Latinas. The aim of this study was to examine changes in muscle-strengthening activity from baseline to 6 and 12 months in Seamos Saludables, a 12-month PA randomized controlled trial for Latinas. Methods: A secondary data analysis was conducted among 131 Latinas ages 18–65 years, who were randomized to either a PA Intervention or a Wellness Control. Self-reported muscle-strengthening exercise was measured at baseline, 6 months, and 12 months via adapted muscle-strengthening questions from the Behavioral Risk Factor Surveillance System. Results: There was a 16-minute/week difference in median minute/week of muscle-strengthening activity between Intervention and Wellness at 6 months ( SE = 7.91, p = .04) and 45-minute/week difference at 12 months ( SE = 25.80, p = .06) adjusting for baseline. Significantly more PA Intervention participants met muscle-strengthening guidelines of 2 or more days/week at 6 months versus Wellness Control participants (odds ratio [OR] = 4.29, 95% confidence interval [CI] = [1.03, 17.84]). Conclusion: Results from the current study showed that Latinas engaged in muscle-strengthening activity in an intervention that emphasized primarily aerobic PA outcomes, suggesting they may be interested in engaging in muscle-strengthening activities. Future interventions targeting both aerobic and muscle-strengthening activity could achieve greater health improvements and help more Latinas reach the full national PA guidelines.

Mindfulness training (MT) may promote medication adherence in outpatients with heart failure.The aims of this study were to determine the feasibility and acceptability of MT (primary outcomes) and explore effects on medication adherence, functional capacity, cognitive function, depression, and mindfulness skills (secondary outcomes).In this pre/post-design study, participants received a 30-minute phone-delivered MT session weekly for 8 weeks.We enrolled 33 outpatients (32% women; 69.7 White; mean age, 60.3 years). Retention was 100%, and session attendance was 91%. Overall, participants (97%) rated MT as enjoyable. Objectively assessed ( Plt; .05) adherence decreased post intervention, whereas improvements were noted in functional capacity ( P = .05), mindfulness ( Plt; .05), and cognitive function (reaching significance for Flanker scores).Phone-delivered MT was feasible and acceptable. Whereas no improvements were noted in medication adherence and depression, cognitive function, functional capacity, and mindfulness levels increased post intervention, suggesting MT may have beneficial effects in outpatients with heart failure.

BACKGROUND Lesbian, gay, bisexual, and other sexual minority (LGB+) girls are more likely than heterosexual girls to be pregnant during adolescence. Nonetheless, LGB+ inclusive pregnancy prevention programming is lacking. METHODS Between January 2017 and January 2018, 948, 14 to 18 year-old cisgender LGB+ girls were enrolled in a national randomized controlled trial. Girls were assigned either to Girl2Girl or an attention-matched control group. They were recruited via social media and enrolled over the telephone. The 5-month intervention consisted of a 7-week program (4–12 text messages sent daily) and a 1-week booster delivered 12 weeks later. Longitudinal models of protected sex events had a negative binomial distribution and a log link function. Longitudinal models examining use of birth control assumed a Bernoulli distribution of the outcome variable and a logit link function. Models adjusted for baseline rate of the outcome, age, and a time-varying indicator of sexual experience. RESULTS Girl2Girl participants had higher rates of protected penile-vaginal sex events over time compared with controls. Girl2Girl participants also were more likely than control participants to report use of birth control other than condoms. Models of abstinence and pregnancy rates did not suggest statistically significant group differences across time. However, effect sizes were in the small to medium range and point estimates favored Girl2Girl versus control in both cases. CONCLUSIONS Girl2Girl is associated with sustained pregnancy preventive behaviors for LGB+ girls through 12 months postintervention. Text messaging could be considered as a viable method to increase access to sexual health programming to adolescents nationally.

Background: Hypertensive disorders of pregnancy are a leading cause of maternal mortality. Racial disparities in maternal mortality in the United States are well-documented, but the role of racism and/or discrimination in affecting one’s risk of developing a hypertensive disorder of pregnancy is not well-studied. Methods: Data from 17 sites that asked questions regarding experiences with racism and/or discrimination during pregnancy via the Pregnancy Risk Assessment Monitoring System (PRAMS) Phase 8 (2016-2020) from was used. Regression models were used to estimate odds of hypertensive disorder diagnosis in pregnancy using adjusted models controlling for cofounders: biological risk factors, socioeconomic factors, and experiences of racism and/or discrimination. Results: Among participants with live births (N = 69,751), 14.9% of participants stated they were diagnosed with hypertension during pregnancy with non-Hispanic and Hispanic Black individuals having the highest rates (19.8%). 13.1% of participants experienced racism and 15.6% of participants experienced discrimination. Experiencing racism or discrimination increased one’s odds of having hypertension during pregnancy by 1.14 times (CI: 1.00 - 1.31) and 1.30 times (CI: 1.02 - 1.65), respectively. When experiences with discrimination were included, non-Hispanic and Hispanic Black individuals did not have statistically significantly higher odds of having hypertension during pregnancy compared to non-Hispanic White individuals. Conclusions: Experiences of racism and/or discrimination drive racial disparities in hypertensive disorders in pregnancy. Public Health Implications: It is vital to eliminate racist and discriminatory practices in healthcare to reduce maternal morbidity and mortality.

The present study examined associations between sleep and physical activity among a diverse sample of 97 urban children (ages 7-9) with persistent asthma. Differences in associations were evaluated by race/ethnicity and weight status. The extent to which sleep moderated the association between lung function and physical activity was also evaluated. Generalized linear models were utilized to examine associations. Findings indicated that, among the aggregate sample, more frequent nighttime awakenings were associated with less time spent engaging in moderate-to-vigorous physical activity (MVPA). Important differences in these associations were identified by both race/ethnicity and weight status. Better lung function was associated with, (a) higher levels of MVPA for children with better sleep efficiency and fewer nighttime awakenings, and (b) lower levels of MVPA for children with poorer sleep efficiency and more frequent nighttime awakenings. In short, sleep mattered with respect to children's physical activity levels in this sample.

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 = −.72, SE = .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.

Background Peer support can extend the reach of physical activity (PA) interventions. In previous studies, peer support via weekly counseling calls increased PA at 3 and 6 months among breast cancer survivors, compared to contact control. However, effects were attenuated at 6 months. Interventions targeting PA maintenance among cancer survivors are limited. Hence, we extended prior work to identify effective PA maintenance interventions. Purpose Following a 3-month PA intervention, the study compared the effects of three 6-month interventions on PA at 12 months. Methods One hundred and sixty-one inactive breast cancer survivors participated in a 12-month randomized controlled trial. Intervention delivery was uniform for the first 3-months: all participants received a weekly call with their peer coach to encourage PA. Following month 3, participants self-monitored PA and received feedback reports (Reach Plus) or additionally received, a monthly phone call (Reach Plus Phone), or weekly text message (Reach Plus Message). Moderate-to-vigorous PA (MVPA) was measured using self-report (7 Day PAR) and accelerometry at baseline, 3, 6, 9, and 12 months. Results At 3 months, there were significant within group increases in self-reported and objectively measured MVPA with no between-group differences (ps > .05). At 6 months, adjusted longitudinal models showed that Reach Plus Message reported an additional 23.83 (SD = 6.33, f2 = .12) min/week of MVPA and Reach Plus Phone reported an additional 18.14 min/week (SD = 5.15, f2 =.16) versus Reach Plus. Results were similar at 9 months. At 12 months, Reach Plus Message and Reach Plus Phone both out-performed Reach Plus (ps = .04 and .05 respectively and effect sizes f2 = .11 and f2 = .21 respectively). Accelerometer data showed similar patterns: Reach Plus Message and Reach Plus Phone out-performed Reach Plus at 6 (f2 = .20) and 9 months (f2 = .09). Conclusion Phone calls from peer mentors and text messaging can support PA maintenance among breast cancer survivors. Clinical Trial information ClinicalTrials.Gov NCT02694640.

The Young Men and Media study developed and pilot tested a community-informed, online HIV prevention program for adolescent sexual minority males (ASMM) in the United States. The developed intervention uses nine interactive modules to increase sexual health knowledge, promote critical examination of pornography, and decrease sexual risk among ASMM. Participants (N = 154, age 14–17 years) were recruited online in Spring 2020 and randomized to the intervention (n = 77) or other existing HIV websites (n = 77). Of the 65 intervention participants who logged in to the website, most completed all nine modules and found the content useful (average module score 4.3 out of 5 stars). The intervention also showed improved HIV/STI knowledge, increased pornography knowledge, and reduced beliefs that pornography is an accurate depiction of male-male sex. Results indicate that the Young Men and Media intervention is feasible, acceptable, and may positively impact sexual health outcomes.

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.

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.

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.

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.

Non-homeostatic, or hedonic eating can be detrimental to weight control efforts, yet the effect of exercise on hedonic eating is unclear. PURPOSE: This efficacy trial tests the hypothesis that exercise training favorably impacts hedonic eating (i.e., overeating, stress-induced overeating, disinhibited eating, eating when tempted), in a sample of women who are overweight or obese. METHODS: Participants were inactive at baseline, self-identified as ‘stress eaters’, and were randomized to 12 weeks of moderate-intensity exercise training (EX; combination of supervised and objectively-confirmed unsupervised sessions) or to a no-exercise control condition (CON). EX participants were given an exercise goal of 200 min/week. No dietary instructions or weight control strategies were provided. Assessments occurred at baseline and 12 weeks. Overeating episodes, stress-induced overeating, and dietary temptations were measured over 14 days at each assessment using ecological momentary assessment (EMA). Disinhibition and dietary restraint were assessed via questionnaire. RESULTS: 49 participants (age: 40.4±10.8 years, BMI: 32.4±4.1 kg/m(2)) enrolled, and 39 completed this study. Adherence to the exercise intervention was high (99.4% of all prescribed exercise). At week 12, the proportion of eating episodes that were characterized as overeating episodes was lower in EX vs. CON (21.98% in EX vs. 26.62% in control; p=.001). Disinhibition decreased in EX, but not CON (p=.02), and was driven by internal factors. There was a trend, such that CON was more likely to give into dietary temptations (p=0.08). Stress-induced overeating was low, and did not differ between conditions (p=0.61). CONCLUSION: Exercise training reduced the likelihood of overeating, and eating in response to internal cues, in women who self-identified as stress eaters. This may be one pathway by which exercise impacts body weight.

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.

Background Rates of smoking among those with serious mental illness (SMI) are two to three times higher than for the general population. Smoking is rarely addressed in mental health settings. Innovative outreach and treatment strategies are needed to address these disparities. The current study is a pilot study of the feasibility and acceptability of a chronic care model of tobacco cessation treatment implemented in outpatient psychiatry clinics. Methods Participants were recruited from two outpatient psychiatric clinics and randomly assigned to intervention (counseling and nicotine replacement for 8 weeks, plus ongoing proactive outreach calls inviting reengagement in treatment) or control (brief education and referral to the state quit line). Assessments were conducted at 8 weeks (end of initial treatment block) and 6 months (end of window for retreatment). Feasibility was assessed by enrollment rate, treatment engagement, and completion of follow-up assessments. Acceptability was assessed both quantitatively and qualitatively. Preliminary efficacy was assessed by 7-day and 30-day abstinence rates, rate of quit attempts, and cigarettes per day. Psychological health was measured to assess for changes related to treatment group or attempts to quit smoking. Results Nineteen participants were randomized to intervention and 19 to control. Recruitment proved feasible, and high rates of treatment engagement (mean of 4.5 sessions completed in initial treatment block, 89.5% uptake of nicotine replacement) and retention (94.7% of follow-up assessments completed) were observed. Treatment acceptability was high. As anticipated, there were no significant differences in abstinence between groups, but results generally favored the intervention group, including bio-verified 7-day abstinence rates of 21.1% in intervention vs. 17.6% in control and self-reported 30-day abstinence rates of 16.1% in intervention vs. 5.1% in control at 8 weeks. Significantly more intervention participants made at least one quit attempt (94.7% vs 52.6%; OR = 16.20, 95% CI: 1.79–147.01). Cigarettes per day decreased significantly more in the intervention group at 8 weeks (b = − 13.19, SE = 4.88, p = .02). Conclusions It was feasible to recruit and retain SMI patients in a smoking cessation trial in the context of outpatient psychiatry. The novel chronic care model treatment was acceptable to patients and showed promise for efficacy. If efficacious, a chronic care model could be effective at reducing smoking among SMI patients.

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 RCT (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.

Background Given the high prevalence of asthma and obesity in minority children, there is a need to identify targets for intervention to decrease the impact of these conditions on children's functioning in this high-risk group. Objective To examine in urban children with persistent asthma, 1) differences in asthma indicators (eg, FEV1% predicted) by weight status, and by ethnic group/weight status, 2) caregivers’ fears about their child's asthma by weight status, and by ethnic group/weight status, and 3) the proportion of children who qualified for exercise-induced bronchospasm (EIB) via exercise challenge test among those whose caregivers endorse exercise as a trigger for asthma. Methods In this sample of urban children (aged 7–9; N = 147), subjective measures included child/caregiver daily report of asthma symptoms and caregiver fears about their child's asthma. Objective lung function was measured twice daily via handheld spirometer and EIB was confirmed via exercise challenge test. Results In the overall sample, a greater proportion of normal-weight children reported asthma symptoms compared to overweight/obese children. Caregiver fears about asthma were more prevalent among Latino caregivers. Non-Latino White children whose caregivers were afraid their child may die when having asthma reported more days with asthma symptoms. Very few children had confirmed EIB compared to the proportion of caregivers who endorsed exercise as a dangerous trigger for asthma. Conclusions Caregiver fear about asthma and misperceptions of exercise as a dangerous trigger for asthma should be addressed during health care visits with families of children with asthma and interventions including urban children with asthma.

BACKGROUND. Food insecurity affects one in seven households with children in the United States, disproportionately impacts households headed by women and minorities, and is associated with childhood comorbidities, including obesity. While food insecurity likely contributes to poor health through its effect on diet, such a simplistic understanding likely obscures the effects of poverty-related stress and other Adverse Childhood Experiences, on metabolic health. METHODS. Over two summers, 100 children, ages 8-12 years, will be recruited from low-income households in an urban, Rhode Island community, to participate in an 8-week trial designed to isolate the experience of food insecurity. Summer represents a natural risk period of food insecurity in children, such that children will be randomized to receive weekly shipments of five breakfast and lunch meals that mimic school meals or to experience the likely onset of summertime food insecurity and receive a weekly newsletter on community resources that is not expected to affect food insecurity. Through assessment visits at baseline, mid-summer and end of summer, we will examine group differences in change in diet quality, biomarkers of Metabolic Syndrome, inflammation, and stress, BMI z-scores, and child measures of behavior and anxiety and depression symptoms. We will also explore the impact of caregiver mood and stress on the health effects of food insecurity. CONCLUSIONS. Findings stand to clarify the mechanisms by which food insecurity affects child health outcomes and to inform how to best address food insecurity in the context of poverty-related stress.

Background: Latina adolescents 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) suggest 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) currently engaging in ≤150 minutes/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 receive a one-on-one goal setting session followed by six 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 six 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, changes in psychosocial constructs, including social support and self-efficacy, engagement with mobile technology channels, and costs of intervention delivery. We are also examining potential mediators and moderators of the intervention. 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 a critical health behavior, physical activity, in Latina teens, a population with high lifetime risk of lifestyle-related diseases. Results will speak to the efficacy and acceptability of the intervention, which has potential for broad dissemination.

Introduction Supine sleep position during pregnancy has been linked to increased risk of stillbirth in retrospective studies. However, existing literature is largely cross-sectional and limited by recall bias and self-reporting of sleep position. This study aims to use objectively-measured sleep position to quantify sleep position change between trimesters and its influence on maternal respiratory health. Methods This study is a secondary analysis of data from a study investigating maternal sleep, among women with singleton pregnancies and overweight or obesity. Each participant underwent level III sleep apnea monitoring using Noxturnal T3 devices (Nox Medical, Georgia, US), in the first (0-12 weeks) and third (29-40 weeks) trimester of pregnancy. Using accelerometry, the software differentiated 5 positions including supine, right lateral, left lateral, prone, and upright. The studies were scored using AASM 2012 recommended criteria. The first non-upright position was recorded as going-to-bed position. The number of sleep position changes was calculated using only positions that lasted ≥30 seconds. Results A total of 126 women were included. Mean BMI was 34.00±5.14 and mean age was 30.46±5.40 years. Mean number of position changes was similar in early (14.19±7.82) vs. late (14.58±8.25) pregnancy. There was a significant correlation between sleep onset position and predominant sleep position in both early (p=0.001) and late (p Conclusion Going-to-bed position predicts predominant sleep position in less than half of women with overweight and obesity. Time spent supine in late pregnancy correlates with measures of sleep-disordered breathing. More prospective studies are needed to evaluate the potential for sleep position changes over time as a potentially modifiable risk factor for maternal and neonatal health outcomes.

Background App-based interventions provide a promising avenue for mitigating the burden on mental health services by complimenting therapist-led treatments for anxiety. However, it remains unclear how specific systems’ use of app features may be associated with changes in mental health outcomes (eg, anxiety and worry). Objective This study was a secondary analysis of engagement data from a stage 1 randomized controlled trial testing the impact of the Unwinding Anxiety mobile app among adults with generalized anxiety disorder. The aims of this study were 2-fold: to investigate whether higher microengagement with the primary intervention feature (ie, educational modules) is associated with positive changes in mental health outcomes at 2 months (ie, anxiety, worry, interoceptive awareness, and emotional reactivity) and to investigate whether the use of adjunctive app features is also associated with changes in mental health outcomes. Methods We analyzed the intervention group during the stage 1 trial of the Unwinding Anxiety mobile app. The total use of specific mobile app features and the use specific to each feature were calculated. We used multivariate linear models with a priori significance of α=.05 to investigate the impact of cumulative app use on anxiety, worry, interoceptive awareness, and emotional regulation at 2 months, controlling for baseline scores, age, and education level in all models. Significant relationships between system use metrics and baseline participant characteristics were assessed for differences in use groupings using between-group testing (ie, 2-tailed t tests for continuous data and chi-square analyses for categorical data). Results The sample was primarily female (25/27, 93%), and the average age was 42.9 (SD 15.6) years. Educational module completion, the central intervention component, averaged 20.2 (SD 11.4) modules out of 32 for the total sample. Multivariate models revealed that completing >75% of the program was associated with an average 22.6-point increase in interoceptive awareness (b=22.6; SE 8.32; P=.01; 95% CI 5.3-39.8) and an 11.6-point decrease in worry (b=−11.6; SE 4.12; P=.01; 95% CI −20.2 to −3.1). In addition, a single log unit change in the total number of meditations was associated with a 0.62-point reduction in the Generalized Anxiety Disorder-7 scale scores (b=0.62; SE 0.27; P=.005; 95% CI −1.2 to −0.6), whereas a single log unit use of the stress meter was associated with an average of a 0.5-point increase in emotional regulation scores (Five Facet Mindfulness Questionnaire; b=0.5; SE 0.21; P=.03; 95% CI 0.1-0.9). Conclusions This study offers a clearer understanding of the impact of engagement with app features on broader engagement with the health outcomes of interest. This study highlights the importance of comprehensive investigations of engagement during the development of evidence-based mobile apps.

BACKGROUND Mobile health applications provide a promising avenue to help mitigate the burden on mental health services by complimenting therapist-led treatments for anxiety. However, it remains unclear how specific systems' use of application components (i.e., tools) may be associated with changes in clinical symptomatology (i.e., anxiety, worry). OBJECTIVE This study was a secondary analysis of systems usage data from the Stage I randomized controlled trial testing the impact of the Unwinding Anxiety mobile application among adults with GAD. This secondary analysis was conducted to assess how using specific application tools may be associated with improvements in anxiety, worry, emotional regulation, and interoceptive awareness. METHODS We present analyses of the intervention group (i.e., those who received the Unwinding Anxiety program) during the Stage 1 trial. Total use of specific mobile application tools (i.e., ecological tools, meditation practices, educational modules) as well use specific to each tool (e.g., stress meter, lovingkindness meditation practice) were calculated. We utilized multivariate linear models to investigate the effect of total use of these tools on anxiety, worry, interoceptive awareness, emotional regulation at 2-months post-program initiation controlling for baseline scores, age, and education level. In addition, associations between systems usage metrics and baseline participant characteristics were assessed for differences in usage groupings. RESULTS The sample was primarily female (n=25; 92.6%) and the average age was 42.9 years old (SD=15.6) and educational module completion, the central intervention component, averaged 20.2 + 11.4 modules out of XXX for the total sample. Multivariate models revealed that completing >75% of the program was associated with an average 22.6-point increase in interoceptive awareness (SE=8.32, p=0.013) and an 11.6-point decrease in worry (SE=4.12, p=0.009). In addition, a single log unit change in total number of meditations was associated with a 0.95-point reduction in GAD-7 scores (SE=0.27, p=0.005) while a single log unit use of the stress meter was associated with an average of a 0.5-point increase in emotional regulation scores (FFMQ) (SE=0.21, p=0.027). CONCLUSIONS The work presented offers a clearer understanding of the impact of specific mobile app systems use on mental health outcomes. In addition, this research lays the groundwork for future comprehensive investigations of systems usage in dosing studies for health behavior change.

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 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.

The present study examined associations between sleep and physical activity among a diverse sample of 97 urban children (ages 7-9) with persistent asthma. Differences in associations were evaluated by race/ethnicity and weight status. The extent to which sleep moderated the association between lung function and physical activity was also evaluated. Generalized linear models were utilized to examine associations. Findings indicated that, among the aggregate sample, more frequent nighttime awakenings were associated with less time spent engaging in moderate-to-vigorous physical activity (MVPA). Important differences in these associations were identified by both race/ethnicity and weight status. Better lung function was associated with, (a) higher levels of MVPA for children with better sleep efficiency and fewer nighttime awakenings, and (b) lower levels of MVPA for children with poorer sleep efficiency and more frequent nighttime awakenings. In short, sleep mattered with respect to children's physical activity levels in this sample.

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 (PLWH). 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.

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. OBJECTIVE: Affective response to PA was examined as a putative mediator of the association between perceptions of the PA environment and subsequent PA behavior. METHODS: As part of a PA promotion pilot 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. RESULTS: 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

Survival rates among cancer survivors have improved; however, treatments affect body esteem. Body esteem can significantly affect quality of life and depression following cancer treatment. The purpose of these secondary analyses was to examine the relationship between changes in fitness and body fat with changes in body esteem among colorectal cancer survivors who participated in a randomized controlled trial that tested the effects of a 12-week physical activity intervention. Male and female colorectal cancer survivors (

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 Conclusions: The moderate-intensity group compared with the high-intensity group is more effective at improving affect and energy and at reducing distress.
