Results from the Strong Families Start at Home/Familias Fuertes Comienzan en Casa: feasibility randomised control trial to improve the diet quality of low-income, predominantly Hispanic/Latinx children.

OBJECTIVE: To describe the feasibility, acceptability and results of Strong Families Start at Home, a 6-month pilot trial of a home-based food parenting/nutrition intervention. DESIGN: Pilot randomised controlled trial. SETTING: Participants received six visits with a community health worker trained in motivational interviewing (three home visits, three phone calls); an in-home cooking or reading activity; personalised feedback on a recorded family meal or reading activity; text messages and tailored printed materials. PARTICIPANTS: Parents and their 2-5-year-old child were randomised into intervention (responsive food parenting practices/nutrition) or control (reading readiness) groups. RESULTS: Parents (n 63) were mostly mothers (90 %), Hispanic/Latinx (87 %), born outside the USA (62 %), with household incomes <$25 k (54 %). Despite delivery during COVID-19, 63 % of dyads were retained at 6 months. The intervention was delivered with high fidelity. All parents in the intervention group (n 24) expressed high levels of satisfaction with the intervention, which produced positive treatment effects for whole and total fruit component Healthy Eating Index-2015 scores (point estimate (PE) = 2·14, 95 % CI (0·17, 1·48); PE = 1·71, 95 % CI (0·16, 1·47), respectively) and negative treatment effects for sodium (PE = -2·09, 95 % CI (-1·35, -0·04)). Positive treatment effects also resulted for the following food parenting practices: regular timing of meals and snacks (PE = 1·08, 95 % CI (0·61, 2·00)), reducing distractions during mealtimes (PE = -0·79, 95 % CI (-1·52, -0·19)), using food as a reward (PE = -0·54, 95 % CI (-1·35, -0·04)) and providing a supportive meal environment (PE = 0·73, 95 % CI (0·18, 1·51)). CONCLUSION: Given the continued disparities in diet quality among low-income and diverse families, continued efforts to improve child diet quality in fully powered intervention trials are needed.

Mediation of the association between social environmental characteristics of family childcare home and weight status in children by diet quality.

BACKGROUND: The food and beverages served in family childcare homes (FCCHs) may play an important role in the development of childhood overweight and obesity. This analysis examines whether children's diet quality mediates the relationship between foods and beverages served in FCCHs and preschool-aged children's weight status. METHODS: Trained and certified staff conducted observations for two days in each FCCH, using the Environment and Policy Assessment and Observation (EPAO) measure to determine the foods and beverages served to children (N = 370) in FCCHs (N = 120). They also used the Dietary Observation in Child Care (DOCC) protocol to assess children's food and beverage intake during childcare, from which we calculated the Healthy Eating Index-2015 (HEI), a measure of diet quality. Height and weight were measured for each child with parent consent from which the child's body mass index (BMI) z-scores were calculated. A multilevel mediation analysis was conducted to indicate whether children's diet quality mediates the relations between food and beverage served in FCCHs and preschool-aged children's weight status. RESULTS: Children's total HEI scores significantly mediated the relationship between the EPAO subscale Food Provided and children's BMI z-scores (B=-0.01, p < .05, 95% CI = [-0.03, - 0.002]). Further, the EPAO subscale Food Provided was positively associated with the total HEI score (B = 0.75, p < .01, 95% CI = [0.32, 1.18]). Total HEI scores were negatively associated with BMI z-score (B=-0.01, p < .05, 95% CI = [-0.02, - 0.001]). CONCLUSION: Children's diet quality did significantly mediate the relationship between the food served in FCCHs and children's weight status. More longitudinal studies with longer follow-up periods need to be conducted to confirm these relationships. Further, future studies need to examine the relationships between a broader spectrum of FCCH environmental characteristics and home environment with children's weight status, as well as other mediators including physical activity.

Home Visitation Program Staff Attitudes and Intentions Towards Using Digital Technology to Educate Families About Preventing Early Childhood Obesity: A Qualitative Study.

INTRODUCTION: Home visitation programs that reach families of young children offer a unique opportunity for large-scale early childhood obesity prevention efforts. The objective of this qualitative research was to determine stakeholder attitudes, subjective norms, perceived ease of use and usefulness, behavioral control, and behavioral intentions towards utilizing technology in a home visitation program targeting early childhood obesity prevention. METHODS: Staff from the Florida Maternal, Infant, and Early Childhood Home Visiting Program (n = 27) were interviewed individually by a trained research assistant using a semi-structured script based on constructs from the Technology Acceptance Model and Theory of Planned Behavior. Demographic and technology use information were collected. Interviews were recorded and transcribed verbatim, with data extracted and coded by two trained researchers using a theoretical thematic analysis approach. RESULTS: Most of the home visiting staff (78%) were white and non-Hispanic and employed for an average of 5 years with the program. Most staff (85%) indicated they were currently using videoconferencing for home visits. Themes and subthemes emerged, including positive attitudes towards technology as a flexible and time-efficient program alternative for childhood obesity prevention with recommendations to keep content short, at a low literacy level, and available in more than one language for ease of use. Participants recommended developing training tutorials to improve program implementation. Internet access and potential social disconnect were cited as concerns for using technology. DISCUSSION: Overall, home visitation staff had positive attitudes and intentions for using technology in home visiting programs with families for early childhood obesity prevention.

The Hombres Saludables Physical Activity Web-Based and Mobile Phone Intervention: Pilot Randomized Controlled Trial With Latino Men.

BACKGROUND: Owing to structural-level, interpersonal-level, and individual-level barriers, Latino men have disproportionately high rates of physical inactivity and experience related chronic diseases. Despite these disparities, few physical activity (PA) interventions are culturally targeted for Latino men. OBJECTIVE: This study reported the feasibility and acceptability of Hombres Saludables PA intervention for Latino men. We also reported the preliminary efficacy of the intervention on PA change and provided the results of the exploratory moderator and mediator analysis. METHODS: We completed a 6-month, single-blind, pilot randomized controlled trial of Hombres Saludables with Latino men aged between 18 and 65 years. Men were randomized to either (1) a theory-driven, individually tailored, internet-based and SMS text message-based, Spanish-language PA intervention arm or (2) a nutrition and wellness attention contact control arm that was also delivered via the web and SMS text message. We assessed the primary study outcomes of feasibility using participant retention and acceptability using postintervention survey and open-ended interview questions. We measured the preliminary efficacy via change in minutes of moderate to vigorous PA per week using ActiGraph wGT3X-BT accelerometry (primary measure) and self-reported minutes per week using 7-day Physical Activity Recall. Participants completed the assessments at study enrollment and after 6 months. RESULTS: The 38 participants were predominantly Dominican (n=8, 21%) or Guatemalan (n=5, 13%), and the mean age was 38.6 (SD 12.43) years. Retention rates were 91% (21/23) for the PA intervention arm and 100% (15/15) for the control arm. Overall, 95% (19/20) of the intervention arm participants reported that the Hombres study was somewhat to very helpful in getting them to be more physically active. Accelerometry results indicated that participants in the intervention group increased their PA from a median of 13 minutes per week at study enrollment to 34 minutes per week at 6 months, whereas the control group participants showed no increases. On the basis of self-reports, the intervention group was more likely to meet the US PA guidelines of 150 minutes per week of moderate to vigorous PA at 6-month follow-up, with 42% (8/19) of the intervention participants meeting the PA guidelines versus 27% (4/15) of the control participants (odds ratio 3.22, 95% CI 0.95-13.69). Exploratory analyses suggested conditional effects on PA outcomes based on baseline stage of motivational readiness, employment, and neighborhood safety. CONCLUSIONS: The PA intervention demonstrated feasibility and acceptability. Results of this pilot study indicate that the Hombres Saludables intervention is promising for increasing PA in Latino men and suggest that a fully powered trial is warranted. Our technology-based PA intervention provides a potentially scalable approach that can improve health in a population that is disproportionately affected by low PA and related chronic disease.

Effect of Applying Best Practices for Physical Activity and Screen Time to Family Childcare Homes.

INTRODUCTION: Early childcare has been identified as an influential setting for children's physical activity. Our objective was to determine whether children aged 2 to 5 years had more accelerometer-measured minutes of physical activity when caregivers in their family childcare home (FCCH) adhered to best practices for physical activity and screen time. METHODS: We analyzed baseline 2-day observation data collected by using the Environment and Policy Assessment and Observation measure from a cluster-randomized trial. Multilevel linear regression models assessed the association between caregivers' meeting best practices for physical activity and screen time and children's time spent sedentary or in moderate-to-vigorous physical activity (MVPA). RESULTS: All FCCH caregivers (N = 120) in our study were female, and 67.5% were Hispanic. Participating children (N = 349) were 52.1% female and 57.4% Hispanic. A higher score among caregivers for physical activity best practices was associated with more MVPA (B = 0.79; 95% CI, 0.02 to 1.56; P = .04) for children and less sedentary time (B = -2.07; 95% CI, -3.94 to -0.19; P = .04). A higher caregiver score for screen time best practices was associated with less sedentary time (B = -2.07; 95% CI, -3.94 to -0.19; P = .04) and more MVPA time (B = 0.65; 95% CI, 0.03 to .27; P = .04). Children in homes where caregivers offered them 60 minutes or more of outdoor play and participated in outdoor physical activity had more MVPA and less sedentary time. We found no association between various screen-time best practices and children's sedentary time. DISCUSSION: Children with caregivers who used more best practices for physical activity and screen time had higher activity levels and spent less time sedentary. These findings could help policy makers and people caring for young children modify existing policies and develop programs to help early childhood caregivers implement best practices to promote children's physical activity.

A multi-component tailored intervention in family childcare homes improves diet quality and sedentary behavior of preschool children compared to an attention control: results from the Healthy Start-Comienzos Sanos cluster randomized trial.

BACKGROUND: Childcare settings are important environments for influencing child eating and physical activity (PA). Family childcare homes (FCCH) care for many children of low-income and diverse racial/ethnic backgrounds who are at greater risk for poor diet quality, low PA, and obesity, but few interventions have targeted this setting. The aim of this study was to assess the efficacy of a multicomponent intervention conducted in FCCH on the diet quality and PA of 2-5 year old children in their care. TRIAL DESIGN: Cluster randomized trial. METHODS: The cluster-randomized trial, Healthy Start/Comienzos Sanos (2015-2019) evaluated an 8-month nutrition and PA intervention that included four components: (1) monthly telephone calls from a support coach using brief motivational interviewing, (2) tailored reports, newsletters and videos, (3) group support meetings, and (4) active play toys. After completing baseline measurement, FCCH were randomized into intervention or comparison groups in matched pairs. Both groups received the same intervention components but on different topics (intervention: nutrition/PA vs. comparison: reading readiness/literacy). Evaluation staff were blinded to group assignment. Child primary outcome measures collected at baseline and 8-months included: 1) Healthy Eating Index (HEI-2015) scores calculated from diet observation, and 2) accelerometer measurement of PA. Process measures were collected from field data and provider surveys. Generalized Estimating Equation Models assessed changes in HEI-2015 scores and PA over time by experimental condition. RESULTS: Ethnically diverse FCCH providers (n = 119) and 2-to-5-year-old children in their care (n = 377) were included in the final analysis. Process evaluation showed high participation in all intervention components except for group meetings. Compared to children in comparison group FCCH, children in intervention FCCH increased total HEI-2015 scores by 7.2 points (p < .001) including improvement in component scores for vegetables (0.84 points, p = .025) and added sugar (0.94 points, p = .025). For PA, compared to children in the comparison group, children in intervention FCCH decreased sedentary time by 5.7% (p = .021). CONCLUSIONS: The multicomponent Healthy Start intervention was effective in improving diet quality and sedentary behavior of children in FCCH, which demonstrates the promise of obesity prevention interventions in this setting. Future research could include enhancing the Healthy Start intervention to strengthen the PA component, considering virtual peer support, and determining how to best translate and disseminate the intervention into FCCH nationally.

Food insecurity, food parenting practices, and child eating behaviors among low-income Hispanic families of young children.

Food insecurity is associated with negative food parenting practices that may promote child obesity, including pressure to eat and food restriction. Less is known about the relationship between food insecurity and positive food parenting practices, including exposing the child to new foods and involving the child in food preparation. Further, few studies have investigated the associations between food insecurity and child eating behaviors that have been linked to poor dietary outcomes. Using baseline data collected as part of a larger pilot intervention, we examined the relationships between food security status, food parenting practices, and child eating behaviors in a predominately Hispanic, low-income sample of parents and their preschool aged children (n = 66). Between July of 2019 and 2020, caregivers recruited from 4 urban communities in Rhode Island completed assessments of household food security, food parenting practices, and four child eating behaviors: food responsiveness, emotional overeating, enjoyment of food, and satiety responsiveness. Although 46% of caregivers reported food insecurity, food insecurity was not directly associated with any food parenting practice. Children in food insecure households were rated as higher in levels of food responsiveness and enjoyment of food as compared to children in food secure households. Children in food insecure households were rated as lower in satiety responsiveness as compared to children in food secure households. Child emotional overeating did not vary by food security status. Future interventions to reduce child obesity among low-income Hispanic families should assess food security status and consider any level of food insecurity as a potential signal of unhealthy child eating behaviors.

Online administration of a pilot mindfulness-based intervention for adolescents: Feasibility, treatment perception and satisfaction.

Adolescents may be more vulnerable to COVID-19-related impacts and require long-term mental health care. Services that bolster emotion regulation, such as mindfulness-based interventions (MBIs) promote positive impacts on psychosocial outcomes and have high acceptability. No studies have assessed feasibility, treatment perceptions and satisfaction of online MBIs with adolescents. 56 moderate- and high-risk adolescent (m = 14.5 years, 66.1% female, 26.8% LatinX) participants tested the feasibility, treatment perceptions and satisfaction of an 8-session online MBI focused on observing non-judgmentally, attending to positivity, and self-soothing. The study achieved acceptable feasibility with high attendance (m = 5.75) and retention rates (87.5%). The moderate- vs. high-risk group reported significantly higher ratings of treatment perceptions (t = 2.03, p < .05, d = 0.60). Significant associations were found between increased pre-test depression and anxiety symptomology and reduced intervention utility (rs = -0.34 and -0.32, ps < .05). This study demonstrated feasibility, treatment perceptions and satisfaction of an online MBI for adolescents presenting with two risk levels. Higher-risk adolescents may need a higher-touch intervention than moderate-risk, who may be more likely to find online MBIs acceptable. The impact of adjunctive MBIs for adolescents on treatment attendance and mental health outcomes over longer periods is necessary to understand patterns in effective adolescent treatment options.

Correlates of Objectively Measured Sleep and Physical Activity Among Latinx 3-To-5-Year Old Children.

PURPOSE: Latinx children have the highest prevalence of obesity in the US. Physical activity (PA) and sleep are important risk factors for this health disparity, yet limited evidence exists examining objectively measured data among this population. We aim to identify correlates of sleep and PA, as well as the association between sleep and PA, among a sample of Latinx children. DESIGN AND METHODS: A cross-sectional study was conducted with thirty Latinx 3-to-5-year old children who wore GT3X+ triaxial accelerometers for five consecutive days, from which we examined sleep and PA constructs. Linear regression and ANOVA were used to examine study constructs. RESULTS: Sedentary behavior, light PA, and MVPA (moderate-to-vigorous PA) were 51.7, 5.6, and 2.6 min/h respectively. Total sleep duration averaged 9.6 h, sleep efficiency averaged 80.0%, and sleep variability averaged 1.30 h/night. Higher household income was associated with sleep variability (F = 7.240, p = .012) and lower sedentary behavior (F = 5.481, p = .027), and higher sleepiness was associated with lower MVPA (ß = -0.503, p = .005) and higher child BMI (ß = 0.531, p = .033). MVPA was associated with higher sleep efficiency (ß = 0.441, p = .016). CONCLUSIONS: Household income emerged as a correlate of sleep variability and sedentary behavior in our study. In addition, we found that MVPA levels were associated with sleep efficiency. PRACTICE IMPLICATIONS: Our results signal an impetus for further research (particularly with larger, multi-site study designs) examining study constructs among Latinx children.

Exploring Parenting Contexts of Latinx 2-to-5-Year Old Children's Sleep: Qualitative Evidence Informing Intervention Development.

PURPOSE: Poor sleep quality is associated with childhood obesity, and Latinx children have the highest prevalence of obesity in the United States. Parents are key agents to ensuring good sleep quality among children, but limited research has examined sleep parenting among Latinx working parents who may have added responsibilities. DESIGN AND METHODS: Working Latinx parents of 2-to-5-year old children participated in in-depth interviews exploring parenting and familial contexts of child sleep. Main topics in the interview guide included sleep-related parenting practices, social support, cultural influences, and intervention service delivery and content preferences. Thematic analysis was used to analyze data. RESULTS: Twenty parents completed the interview. The following themes emerged: Sleep parenting, sleep knowledge, impact of familial structures, family commitments, child temperament, and broader contextual factors on sleep, and intervention content and design ideas. Across participants, employment was reported to be a barrier to effective sleep parenting. Parents also reported engaging in practices that may interfere with sleep quality such as using screen time as a distraction and reducing naptime during the weekends to increase the amount of family time. Family-level factors such as co-parenting and spousal support were reported to facilitate sleep parenting. Participants also indicated the need for more sleep parenting knowledge and a preference for mobile platforms and social media to deliver information. CONCLUSIONS: Results not only fill critical gaps in the literature, but also highlight the variability in parents' approaches to sleep parenting and an urgent need for intervention/programming efforts to target Latinx parent's sleep knowledge and parenting.

Improving nutrition and physical activity environments of family child care homes: the rationale, design and study protocol of the 'Healthy Start/Comienzos Sanos' cluster randomized trial.

BACKGROUND: Early childhood is a crucial time to foster healthy eating and physical activity (PA) habits, which are critical for optimal child health, growth and development. Child care facilities are important settings to promote healthy eating and PA and prevent childhood obesity; however, almost all prior intervention studies have focused on child care centers and not family child care homes (FCCH), which care for over 1.6 million U.S. children. METHODS: This paper describes Healthy Start/Comienzos Sanos, a cluster-randomized trial evaluating the efficacy of a multicomponent intervention to improve nutrition and PA environments in English and Spanish-speaking FCCH. Eligible child care providers complete baseline surveys and receive a two-day FCCH observation of the home environment and provider practices. Parent-consented 2-5 year-old children are measured (height, weight, waist circumference), wear accelerometers and have their dietary intake observed during child care using validated protocols. FCCH providers are then randomly assigned to receive an 8-month intervention including written materials tailored to the FCCH providers' need and interest, videos, peer support coaching using brief motivational interviewing, and periodic group meetings focused on either nutrition and PA (Intervention) or reading readiness (Comparison). Intervention materials focus on evidence-based nutrition and physical activity best practices. The initial measures (surveys, two-day observation of the FCCH and provider practices, child diet observation, physical measures, and accelerometer) are assessed again 8 and 12 months after the intervention starts. Primary outcomes are children's diet quality (Healthy Eating Index), time in moderate and vigorous PA and sedentary PA during child care. Secondary outcomes include FCCH provider practices and foods served, and PA environments and practices. Possible mediators (provider attitudes, self-efficacy, barriers and facilitators) are also being explored. Process evaluation measures to assess reach, fidelity and dose, and their relationship with dietary and PA outcomes are included. DISCUSSION: Healthy Start/Comienzos Sanos fills an important gap in the field of childhood obesity prevention by rigorously evaluating an innovative multicomponent intervention to improve the nutrition and physical activity environments of FCCH.

Association Between Physical Activity Intervention Website Use and Physical Activity Levels Among Spanish-Speaking Latinas: Randomized Controlled Trial.

BACKGROUND: The internet's low cost and potential for high reach makes Web-based channels prime for delivering evidence-based physical activity (PA) interventions. Despite the well-studied success of internet-based PA interventions in primarily non-Hispanic white populations, evidence on Spanish-speaking Latinas' use of such interventions is lacking. The recent rise in technology use among Latinas in the United States, a population at heightened risk for low PA levels and related conditions, suggests that they may benefit from Web-based PA interventions tailored to their cultural and language preferences. OBJECTIVE: The goal of the research was to examine participant engagement with various features of an internet-based PA intervention for Latinas and explore how use of these features was differentially associated with adoption and maintenance of PA behavior change. METHOD: Pasos Hacia la Salud tested a Spanish-language, culturally adapted, individually tailored, internet-based PA intervention versus a Spanish language, internet-based, Wellness Contact Control condition for underactive Latinas (N=205, mean age 39.2 [SD 10.5] years, 84% Mexican American). These analyses examined engagement with the website and explored how use was associated with adoption and maintenance of moderate to vigorous physical activity (MVPA) behavior. RESULTS: Overall, participants logged on to the website an average of 22 times (SD 28) over 12 months, with intervention participants logging on significantly more than controls (29 vs 14.7, P<.001). On average, participants spent more time on the website at months 1, 4, and 6 compared to all other months, with maximum use at month 4. Both log-ins and time spent on the website were significantly related to intervention success (achieving higher mean minutes of MVPA per week at follow-up: b=.48, SE 0.20, P=.02 for objectively measured MVPA and b=.74, SE 0.34, P=.03 for self-reported MVPA at 12 months, controlling for baseline). Furthermore, those meeting guidelines by the Centers for Disease Control and Prevention for PA at 12 months (≥150 minutes per week of MVPA) logged on significantly more than those not meeting guidelines (35 vs 20 over 12 months, P=.002). Among participants in the intervention arm, goal-setting features, personal PA reports, and PA tips were the most used portions of the website. Higher use of these features was associated with greater success in the program (significantly more minutes of self-reported MVPA at 12 months controlling for baseline). Specifically, one additional use of these features per month over 12 months translated into an additional 34 minutes per week of MVPA (goals feature), 12 minutes per week (PA tips), and 42 minutes per week (PA reports). CONCLUSIONS: These results demonstrate that greater use of a tailored, Web-based PA intervention, particularly certain features on the site, was significantly related to increased PA levels in Latinas.

Multilevel approaches to increase fruit and vegetable intake in low-income housing communities: final results of the 'Live Well, Viva Bien' cluster-randomized trial.

BACKGROUND: Fruit and vegetable (F&V) intake can reduce risks for chronic disease, but is much lower than recommended amounts in most Western populations, especially for those with low income levels. Rigorous research is needed on practical, cost-effective interventions that address environmental as well as personal determinants of F&V intake. This paper presents the results of a cluster randomized controlled trial evaluating the efficacy of 'Live Well, Viva Bien' (LWVB), a multicomponent intervention that included discount, mobile fresh F&V markets in conjunction with nutrition education. METHODS: Fifteen subsidized housing sites in Providence County, Rhode Island (8 intervention and 7 control sites) were randomized using a random number generator. Of these, nine housed elderly and/or disabled residents and six housed families. A total of 1597 adult housing site residents (treatment n = 837; control n = 760) were enrolled (73% women, 54% Hispanic, 17% black, Mean age 54 years). A year-long multicomponent intervention including mobile F&V markets plus nutrition education (e.g. campaigns, DVDs, newsletters, recipes, and chef demonstrations) was implemented at intervention sites. Physical activity and stress interventions were implemented at control sites. Follow-up occurred at 6 and 12 months. The main outcome measure was F&V consumption measured by National Cancer Institute's 'Eating at America's Table All Day Screener'. RESULTS: From baseline to 12 months, the intervention group increased total F&V intake by 0.44 cups with the control group decreasing intake by 0.08 cups (p < .02). Results also showed an increased frequency of F&V eating behaviors compared to the control group (p < .01). There was a clear dose response effect of the F&V markets with participants who reported attending all or most of the markets increasing F&V intake by 2.1 cups and 0.86 cups, respectively compared with less than half cup increases for lower levels of market attendance (p < .05). Use of the DVDs, recipes and taste-testings was also associated with greater increases in F&V intake; however, use of other educational components was not. CONCLUSIONS: LWVB is the first cluster, randomized controlled trial to demonstrate the efficacy of year-round F&V markets on improving F&V intake for low-income adults, which provides an evidence-base to bolster the mission of mobile produce markets. Further, the results more broadly support investment in environmental changes to alleviate disparities in F&V consumption and diet-related health inequities.

Examining neighborhood and interpersonal norms and social support on fruit and vegetable intake in low-income communities.

BACKGROUND: We examined whether neighborhood-, friend-, and family- norms and social support for consumption and purchase of fruits and vegetables (F&V) were associated with F&V intake among low-income residents in subsidized housing communities. We examined baseline data from a study ancillary to the Live Well/Viva Bien intervention. Participants included 290 residents in four low-income subsidized housing sites who were ≥ 18 years of age, English and/or Spanish speaking, and without medical conditions that prevented consumption of F&V. METHODS: Linear regression models examined associations of norms and social support with F&V intake after adjustments for sociodemographic characteristics. RESULTS: In the analysis, neighborhood social support for F&V was associated with a 0.31 cup increase in F&V intake (95% CI = 0.05, 0.57). The family norm for eating F&V and family social support for eating F&V were associated with a 0.32 cup (95% CI = 0.13, 0.52) and 0.42 cup (95% CI = 0.19, 0.64) increase in F&V intake, respectively. CONCLUSIONS: To our knowledge, no other studies have examined neighborhood, family, and peer norms and social support simultaneously and in relation to F&V intake. These findings may inform neighborhood interventions and community-level policies to reduce neighborhood disparities in F&V consumption.

Mediators of a physical activity intervention among women with a family history of breast cancer.

The current study examined mediators of an efficacious physical activity intervention. Women with a mean age of 42.6 (range 23-61) years and a family history of breast cancer were randomized to either an Internet-based physical activity intervention (n = 28) or an active control condition (n = 27) for three months. Data were collected between November 2010 and August 2011. Hypothesized mediators were examined using a product of coefficients model with bootstrapped standard errors. Significant mediation was observed for both self-efficacy and behavioral processes. Specifically, the regression coefficients of the indirect effects ("ab path": unstandardized effect of the intervention on physical activity that occurred through the mediator) were ab = 38.58 (95% confidence interval [CI]: 8.66-92.76) for self-efficacy, and ab = 42.02 (95% CI: 6.76-104.84) for behavioral processes. Other factors examined in this study, including cognitive processes, decisional balance, and perceived risk of breast cancer, were not statistically significant mediators. Findings suggest that self-efficacy and behavioral processes may be key constructs to use in targeting future physical activity interventions among women with a family history of breast cancer.

Physical activity maintenance among Spanish-speaking Latinas in a randomized controlled trial of an Internet-based intervention.

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.

Pasos Hacia La Salud: a randomized controlled trial of an internet-delivered physical activity intervention for Latinas.

BACKGROUND: Internet 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. METHODS: Inactive 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. RESULTS: Increases 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 < 0.01). Increases in objectively measured MVPA were also significantly larger in the Intervention Group (mean differences = 31.0, SE = 10.7, p < .01). The Intervention Group was also significantly more likely to meet national physical activity guidelines at 6 months (OR = 3.12, 95% CI 1.46-6.66, p < .05). CONCLUSION: Findings from the current study suggest that this Internet-delivered individually tailored intervention successfully increased MVPA in Latinas compared to a Wellness Contact Control Internet Group.

A Randomized Clinical Trial of a Tailored Lifestyle Intervention for Obese, Sedentary, Primary Care Patients.

PURPOSE: The aim of the study was to test a tailored lifestyle intervention for helping obese primary care patients achieve weight loss and increase physical activity. METHODS: We conducted a 24-month randomized clinical trial in Rhode Island. Primary care physicians identified obese, sedentary patients motivated to lose weight and increase their moderate to vigorous physical activity. These patients were randomized to 1 of 2 experimental groups: enhanced intervention (EI) or standard intervention (SI). Both groups received 3 face-to-face weight loss meetings. The enhanced intervention group also received telephone counseling calls, individually tailored print materials, and DVDs focused on diet and physical activity. Active intervention occurred in year 1 with a tapered maintenance phase in year 2. RESULTS: Two hundred eleven obese, sedentary patients were recruited from 24 primary care practices. Participants were 79% women and 16% minorities. They averaged 48.6 years of age, with a mean body mass index (BMI) of 37.8 kg/m(2), and 21.2 minutes/week of moderate to vigorous physical activity. Significantly more EI participants lost 5% of their baseline weight than SI participants (group by visit, P <.001). The difference was significant during active treatment at 6 months (37.2% EI vs 12.9% SI) and 12 months (47.8% vs 11.6%), but was no longer significant during the maintenance phase at 18 months (31.4% vs 26.7%,) or 24 months (33.3% vs 24.6%). The EI group reported significantly more minutes of moderate to vigorous physical activity over time than the SI group (group by visit, P = 0.04). The differences in minutes per week at 6 months was 95.7 for the EI group vs 68.3 minutes for the SI group; at 12 months, it was 126.1 vs 73.7; at 18 months, 103.7 vs 63.7, and at 24 months, 101.3 vs 75.4. Similar trends were found for absolute weight loss and the percentage reaching national guidelines for physical activity. CONCLUSION: A home-based tailored lifestyle intervention in obese, sedentary primary care patients was effective in promoting weight loss and increasing moderate to vigorous physical activity, with the effects peaking at 12 months but waning at 24 months.

A multi-level intervention in subsidized housing sites to increase fruit and vegetable access and intake: Rationale, design and methods of the 'Live Well, Viva Bien' cluster randomized trial.

BACKGROUND: Adequate fruit and vegetable (F&V) intake is important for disease prevention. Yet, most Americans, especially low-income and racial/ethnic minorities, do not eat adequate amounts. These disparities are partly attributable to food environments in low-income neighborhoods where residents often have limited access to affordable, healthful food and easy access to inexpensive, unhealthful foods. Increasing access to affordable healthful food in underserved neighborhoods through mobile markets is a promising, year-round strategy for improving dietary behaviors and reducing F&V intake disparities. However, to date, there have been no randomized controlled trials studying their effectiveness. The objective of the 'Live Well, Viva Bien' (LWVB) cluster randomized controlled trial is to evaluate the efficacy of a multicomponent mobile market intervention at increasing F&V intake among residents of subsidized housing complexes. METHODS/DESIGN: One housing complex served as a pilot site for the intervention group and the remaining 14 demographically-matched sites were randomized into either the intervention or control group. The intervention group received bimonthly, discount, mobile, fresh F&V markets in conjunction with a nutrition education intervention (two F&V campaigns, newsletters, DVDs and cooking demonstrations) for 12 months. The control group received physical activity and stress reduction interventions. Outcome measures include F&V intake (measured by two validated F&V screeners at baseline, six-month and twelve-months) along with potential psychosocial mediating variables. Extensive quantitative and qualitative process evaluation was also conducted throughout the study. DISCUSSION: Modifying neighborhood food environments in ways that increase access to affordable, healthful food is a promising strategy for improving dietary behaviors among low-income, racial and ethnic minority groups at increased risk for obesity and other food-related chronic diseases. Discount, mobile F&V markets address all the major barriers to eating more F&V (high cost, poor quality, limited access and limited time to shop and cook) and provide a year-round solution to limited access to healthful food in low-income neighborhoods. LWVB is the first randomized controlled trial evaluating the effectiveness of mobile markets at increasing F&V intake. If proven efficacious at increasing F&V consumption, LWVB could be disseminated widely to neighborhoods that have low access to fresh F&V.

Innovative video tailoring for dietary change: final results of the Good for you! cluster randomized trial.

BACKGROUND: Effective, low-cost approaches are needed to enhance dietary behavior change. While both video and tailoring technology have been effective interventions to improve diet, these approaches have never been combined to study the effectiveness of tailored videos. The purpose of this paper is to discuss the results of Good For You!, a randomized trial that tested the efficacy of innovative, individually tailored videos in helping worksite employees decrease dietary fat and increase fruit and vegetable (F&V) intake. METHODS: Worksites were matched on approximate size, type of company and workforce composition and randomized to one of three experimental conditions: Non-Tailored written information (NT) (n = 14), Tailored Written information (TW) (n = 14), or Tailored Written + Tailored Video (TW + TV) (n = 15). Evaluation was conducted at baseline, 4 and 7 months. We used the NCI Fat Screener and an adapted Food Habits Questionnaire (FHQ) to estimate fat intake and fat-related behaviors, the NCI F&V Screener and F&V Habits Questionnaire (FVHQ) to measure F&V intake and behaviors. Generalized linear models were examined for all outcome measurements. RESULTS: 2525 worksite employees were recruited. At 4 months, dietary fat intake decreased significantly more for TW (-2.95 %) and TW + TV (-3.14%) compared with NT (-2.42%). FHQ scores decreased significantly more for TW + TV than the other two groups. Fruit intake increased the most for TW + TV compared to NT and TW. Both TW (1.30 cups) and TW + TV (1.59 cups) increased F&V intake significantly more than NT (0.78 cups). TW + TV showed the largest increase in F&V behaviors on the FVFQ. At 8 months, dietary fat change continued to be significantly better for TW + TV (-3.48%) than NT (3.01%). F&V intake increased significantly more for the TW + TV group (1.38 cups) compared to the NT group (1.04 cups) and FVHQ changes were significantly greater in TW + TV and TW than for NT. CONCLUSIONS: The tailored intervention participants were more likely to decrease fat and increase F&V intake. The TW + TV group was generally the stronger of the two tailored interventions, especially at the longer term follow-up, demonstrating the promise of tailored video as an intervention to change eating habits. Future studies should explore newer channels and technologies in addition to DVDs for delivering tailored video interventions such as the internet and smart phones.
