Enhancing Behavioral Health Implementation in a Care Coordination Program at a Federally Qualified Health Center: A Case Study Applying Implementation Frameworks.

Federally Qualified Health Centers are charged with providing comprehensive health care in traditionally underserved areas, underscoring their importance in caring for and promoting health equity for the large portion of historically marginalized communities in this setting. There is a significant need to ensure Federally Qualified Health Centers are equipped to appropriately address the immense behavioral health needs common among patients served. Care coordination is an evidence-based model that is increasingly utilized in Federally Qualified Health Centers to improve care equity and outcomes. Addressing and supporting behavioral health needs is a key aspect of such care coordination models. Context-specific considerations and programmatic supports, particularly those that address the needs of care coordinators and the complex patients they serve, are needed to ensure such models can appropriately meet and address the behavioral health concerns of the diverse populations served. The goal of this study was to present a mixed-methods case study that systematically applies implementation frameworks to conduct a needs and context assessment to inform the development and testing of evidence-based practice strategies and implementation support as part of a care coordination program within a partnered Federally Qualified Health Center.

A remotely delivered, peer-led intervention to improve physical activity and quality of life in younger breast cancer survivors.

Younger breast cancer survivors (YBCS) consistently report poorer quality of life (QOL) than older survivors. Increasing physical activity (PA) may improve QOL, but this has been understudied in YBCS. This single arm pilot study evaluated the feasibility and acceptability of a 3-month, peer-delivered, remote intervention to increase PA and improve QOL in YBCS. Data were collected from October 2019 - July 2020. Participants (n = 34, 43.1 ± 5.5 years old, 46 ± 34.4 months post-diagnosis, BMI = 30.2 ± 7.4 kg/m2) completed six video sessions with a trained peer mentor; self-monitored PA with a Fitbit activity tracker; and interacted with a private Fitbit Community for social support. At baseline, 3-and 6-months, participants completed QOL questionnaires and PA was measured through accelerometer (moderate-to-vigorous PA [MVPA]) and self-report (strength and flexibility). A parallel mixed-methods approach (qualitative interviews and quantitative satisfaction survey at 3-months) explored intervention feasibility and acceptability. One-way repeated-measures ANOVAs examined impacts on PA and QOL at 3-and 6-months. The intervention was feasible as evidenced by efficient recruitment, high retention, and adherence to intervention components. Remote delivery, working with a peer mentor, and using Fitbit tools were highly acceptable. From baseline to 3-months, participants increased time spent in objectively measured MVPA, strength, and flexibility exercises, and reported meaningful improvements to body image, fatigue, anxiety, and emotional support. A fully remote, peer-to-peer intervention is an acceptable and promising strategy to increase PA and improve QOL in YBCS. Refinements to the intervention and its delivery should be further assessed in future studies, toward the goal of disseminating an evidence-based, scalable intervention to the growing number of YBCS.Trial registration Prospectively registered as NCT04064892.

Optimal Integration of Behavioral Medicine into Clinical Genetics and Genomics.

Clinical genetics and genomics will exert their greatest population impact by leveraging the rich knowledge of human behavior that is central to the discipline of behavioral medicine. We contend that more concerted efforts are needed to integrate these fields synergistically, and accordingly, we consider barriers and potential actions to hasten such integration.

Two-year outcomes of Faith in Action/Fe en Acción: a randomized controlled trial of physical activity promotion in Latinas.

BACKGROUND: Latina women are less likely to report engaging in leisure-time physical activity (PA) than non-Latina white women. This study evaluated the 24-month impact of a faith-based PA intervention targeting Latinas. METHODS: The study is a cluster randomized controlled trial of a PA intervention or cancer screening comparison condition, with churches as the randomization unit. A total of 436 Latinas (aged 18-65 years) from 16 churches who engaged in low levels of self-report and accelerometer-based PA were enrolled. The experimental condition was a 24-month PA intervention, with in-person classes, social support, and environmental changes, led by community health workers (i.e., promotoras). At baseline, 12-, and 24 months, we assessed changes in accelerometer-based and self-reported moderate to vigorous physical activity (MVPA; primary outcomes). Secondary outcomes were light intensity activity, sedentary time, body mass index (BMI), and waist circumference. RESULTS: After adjusting for sociodemographic factors, a mixed effects analysis found significant increases in self-reported leisure time MVPA (p < 0.005) and marginal increases in accelerometer-assessed MVPA (p < 0.08) 24 months post-baseline in the intervention compared to the attention-control condition. Data showed significant associations between PA class attendance and engaging in MVPA as assessed by self-report and accelerometry. No significant changes were found for light activity, sedentary time, BMI, or waist circumference. CONCLUSIONS: Participants who attended the PA classes at least once a month engaged in significantly higher MVPA compared to those who did not. Maximizing engagement and maintenance strategies to enhance PA maintenance could contribute to important long-term health benefits. TRIAL REGISTRATION: NCT01776632 , Registered March 18, 2011.

Forming Habits, Overcoming Obstacles, and Setting Realistic Goals: A Qualitative Study of Physical Activity Maintenance Among Latinas.

BACKGROUND: The impact of physical activity interventions for Latina women can be enhanced by identifying and implementing strategies to achieve long-term physical activity maintenance. Physical activity promotion research has mainly focused on physical activity initiation and we know little regarding individual, interpersonal, or environmental factors that influence maintenance of physical activity. This study aimed to qualitatively explore and understand factors associated with maintenance and non-maintenance of physical activity among Latinas. METHODS: Semi-structured individual interviews were conducted with 21 Latinas who increased their physical activity as a result of an intervention, and who completed a 3-month maintenance period without contact from research staff. Data were analyzed using thematic analysis. RESULTS: Important facilitators of physical activity maintenance described by participants included having made physical activity a habit; the ability to proactively overcome obstacles to engaging in physical activity, and satisfaction with outcomes obtained from engaging in physical activity. Additional facilitators mentioned by both maintainers and non-maintainers included having motivation, social support, and opportunities to be active. Both maintainers and non-maintainers reported high self-efficacy for PA maintenance in the future. CONCLUSIONS: Guiding intervention participants to form habits and to set realistic expectations could help them to independently continue engaging in physical activity upon completion of physical activity interventions. Teaching them skills to proactively overcome obstacles may also be important for physical activity maintenance.

Church Contextual Factors Associated With Latinx Physical Activity and Park Use.

Churches can be important settings for promoting physical activity (PA) among Latinx populations. Little is known about what factors across the church context-social, organizational, and physical (outdoor spaces)-are associated with Latinx PA to inform faith-based PA interventions. This study investigated associations of church contextual factors with Latinx PA. We used cross-sectional data from a Latinx adult sample recruited from 6 churches that each had a nearby park in Los Angeles, California (n = 373). Linear or logistic regression models examined associations of church PA social support, PA social norms, perceived quality and concerns about the park near one's church, and church PA programming with 4 outcomes: accelerometer-based moderate-to-vigorous PA (MVPA) and self-reported adherence to PA recommendations, use of the park near one's church, and park-based PA. Park quality and concerns were positively associated with using the park near one's church. Church PA programming was positively associated with park-based PA. None of the factors were related to accelerometer-based MVPA or meeting PA recommendations. Findings suggest targeting church PA programming and nearby parks may be key to improving Latinx park use. Church and local parks department partnerships may help enhance park conditions to support churchgoing Latinx PA and health.

Comparing Latino Community Members' and Clinical Staff's Perspectives on Barriers and Facilitators to Colorectal Cancer Screening.

Latinos in the United States have low rates of colorectal cancer (CRC) screening even though CRC is the third leading cause of cancer death among Latinos. This qualitative study aimed to understand and compare the perspectives of clinical staff (CS) and Latino community members (LCMs) in an urban Southern California community regarding barriers and facilitators of CRC screening. Through purposive sampling, 39 LCMs (mean age: 59.4 years, 79.5% female) were recruited to participate in one of five focus groups, and 17 CS (mean age: 38.8 years, 64.7% female) were recruited to participate in semi-structured in-depth interviews, along with a demographic survey. Interviews and focus group recordings were transcribed verbatim, translated, and analyzed using direct content analysis. Demographic data were summarized using descriptive statistics. Findings suggest that CS and LCMs have both similar and opposing perspectives with regard to barriers and facilitators of CRC screening. Themes discussed included attitudes towards CRC screening, CRC knowledge, access to resources, commitments and responsibilities, social support, vicarious learning, patient-provider communication, trust, and social relationships. Study findings can be used to guide interventions and policies to improve access to CRC screening among LCMs.

Expanding Implementation Research to Prevent Chronic Diseases in Community Settings.

Chronic disease prevention continues to be inadequate, overall and in achieving health equity, in spite of the many evidence-based practices and policies (EBPPs) available to address risk behaviors such as unhealthful eating, lack of physical activity, and tobacco use. Although clinical settings are needed for EBPPs that involve medical procedures such as immunization or early detection, dissemination of EBPPs can be effective in a variety of settings such as schools and childcare centers, worksites, social service organizations, and religious organizations. More implementation research is needed to meet challenges of effective application of EBPPs in such community settings, in which primary missions, capacity, cultures, and values do not focus on health services delivery. To address health equity, consideration of social and economic contexts of people reached in these settings is essential. This review presents lessons learned from past studies to guide future implementation research and practice across diverse settings and geographies.

The Association of the Parent-Child Language Acculturation Gap with Obesity and Cardiometabolic Risk in Hispanic/Latino Youth: Results from the Hispanic Community Children's Health Study/Study of Latino Youth (SOL Youth).

BACKGROUND: Hispanic/Latino youth are disproportionately burdened by obesity and have a high prevalence of prediabetes and dyslipidemia. Differences in parent and child acculturation related to language use and preference (i.e., language acculturation) are associated with adverse cardiometabolic health behaviors, but no study has examined associations with cardiometabolic markers. PURPOSE: To determine whether discordance in parent-child language acculturation (parent-child acculturation gap) was associated with poor youth cardiometabolic health. METHODS: Hispanic/Latino 8-16-year-olds (n = 1,466) and parents from the Hispanic Community Children's Health Study/Study of Latino Youth (SOL Youth) were examined. Mean scores for the Brief ARSMA-II's Anglo (AOS) and Latino (LOS) Orientation Scales represented language acculturation. Cardiometabolic markers included youth body mass index (BMI) percentile, blood pressure percentiles, and dysglycemia and hyperlipidemia measures. Missing data were imputed. Survey-weighted multivariable linear regression examined the association of youth, parent, and youth × parent (the acculturation gap) AOS and LOS scores separately with each cardiometabolic marker. RESULTS: Youth reported greater English and lower Spanish use than parents. Greater discordance in AOS scores was associated with elevated BMI percentile only (p-for-interaction < .01). The LOS acculturation gap was not associated with any outcome. Adjustment for acculturative stress, family functioning and closeness, parenting style, and youth's diet and physical activity did not alter findings. Removal of nonsignificant acculturation gaps did not indicate an association between individual youth or parent AOS or LOS scores and any cardiometabolic marker. CONCLUSIONS: Discordance in Hispanic/Latino parent-child dyads' English use may relate to increased risk for childhood obesity. Future studies should identify mediators of this association.

Demographic and sociocultural risk factors for adulthood weight gain in Hispanic/Latinos: results from the Hispanic Community Health Study / Study of Latinos (HCHS/SOL).

BACKGROUND: United States (US) Hispanic/Latinos experience a disproportionate burden of obesity, which may in part be related to demographic or sociocultural factors, including acculturation to an US diet or inactive lifestyle. Therefore, we sought to describe the association between adulthood weight histories and demographic and sociocultural factors in a large diverse community-based cohort of US Hispanic/Latinos. METHODS: We estimated the effect of several factors on weight gain across adulthood, using multivariable linear mixed models to leverage 38,759 self-reported current body weights and weight histories recalled for 21, 45 and 65 years of age, from 15,203 adults at least 21 years of age at the baseline visit of the Hispanic Community Health Study/Study of Latinos (2008-2011). RESULTS: The average rate of weight gain was nearly 10 kg per decade in early adulthood, but slowed to < 5 kg a decade among individuals 60+ years of age. Birth cohort, gender, nativity or age at immigration, Hispanic/Latino background, and study site each significantly modified the form of the predicted adulthood weight trajectory. Among immigrants, weight gain during the 5 years post-migration was on average 0.88 kg (95% CI: 0.04, 1.72) greater than the weight gain during the 5 years prior. The rate of weight gain appeared to slow after 15 years post-migration. CONCLUSIONS: Using self-reported and weight history data in a diverse sample of US Hispanic/Latinos, we revealed that both demographic and sociocultural factors were associated with the patterning of adulthood weight gain in this sample. Given the steep rate of weight gain in this population and the fact that many Hispanic/Latinos living in the US immigrated as adults, efforts to promote weight maintenance across the life course, including after immigration, should be a top priority for promoting Hispanic/Latino health and addressing US health disparities more broadly.

Lapse, Relapse, and Recovery in Physical Activity Interventions for Latinas: a Survival Analysis.

BACKGROUND: Physical activity (PA) research extensively focuses on initiation of PA, yet lapse and relapse among PA intervention participants are less well understood, particularly among minority populations such as Latinas in the USA. This study aimed to (1) determine the probability of lapse during two PA interventions for Latinas; (2) assess demographic, psychosocial, and environmental predictors of the amount of time until first lapse; and (3) identify factors predictive of lapse recovery. METHODS: Data from 176 Latina intervention participants were pooled. Survival functions and Kaplan-Meier curves were used to illustrate probability of lapse. Cox proportional hazard models assessed predictors of time to lapse. Logistic regressions identified predictors of lapse recovery. RESULTS: The probability of lapse after 1 month of starting to exercise was 18%, escalating to 34% after 4 months. Predictors of earlier lapse included various psychosocial constructs (i.e., self-efficacy and various processes of change), but none of the measured environmental factors, and only one demographic factor (≥ 2 children under 18). Increased use of consciousness raising at 2 months was associated with lower likelihood of lapse recovery, yet use of behavioral processes of change at 6 months was associated with higher likelihood of recovery. CONCLUSIONS: Lapsing may not be pre-determined by demographic and environmental characteristics. On the other hand, skills that can be learned through interventions, such as skills to improve self-efficacy, seem important in the delay or prevention of lapses. Results pertaining to lapse recovery are less clear.

Educating the Next Generation of Undergraduate URM Cancer Scientists: Results and Lessons Learned from a Cancer Research Partnership Scholar Program.

To improve cancer disparities among under-represented minority (URM) populations, better representation of URM individuals in cancer research is needed. The San Diego State University and University of California San Diego Moores Cancer Center Partnership is addressing cancer disparities through an educational program targeting undergraduate URM students. The Partnership provides a paid intensive summer research internship enriched with year-round activities that include educational sessions, a journal club, mentorship, social activities, and poster sessions and presentations. Program evaluation through follow-up surveys, focus groups, and other formal and informal feedback, including advisory and program steering committees, are used to improve the program. Long-term follow-up among scholars (minimum of 10 years) provides data to evaluate the program's long-term impact on scholars' education and career path. Since 2016, 63 URM undergraduate students participated in the scholar program. At the year-2 follow-up (2016 cohort; n = 12), 50% had completed their Graduate Record Examination (GRE) and/or applied to graduate or medical school. Lessons learned during the course of the program led to implementation of changes to provide a better learning experience and increase overall program satisfaction. Updates were made to recruitment timeline, improvements of the recruitment processes, refinement of the program contracts and onboarding meetings, identification of essential program coordinator skills and responsibilities, adjustments to program components, and establishment of a well-mapped and scheduled evaluation plan. The Partnership identified best practices and lessons learned for implementing lab-based internship scholar programs in biomedical and public health fields that could be considered in other programs.

A Promotor-Led Pilot Study to Increase Colorectal Cancer Screening in Latinos: The Juntos Contra El Cáncer Program.

Background. Latinos have lower colorectal cancer (CRC) screening rates compared to other racial/ethnic groups in the United States, despite an overall increase in CRC screening over the past 10 years. To address this disparity, we implemented a promotor-led intervention to increase CRC screening test adherence in community-based settings, connecting community members with a partnering federally qualified health center. Purpose. To evaluate the Juntos Contra el Cáncer/Together Against Cancer (JUNTOS) intervention, by assessing pre-post changes in (1) CRC screening test adherence and (2) CRC knowledge and perceived barriers to CRC screening. We also assessed the feasibility and acceptability of program activities. Method. JUNTOS was a group-based intervention, delivered by promotores (community health workers), to promote CRC screening test adherence among Latino adults. The intervention consisted of a culturally tailored 2½-hour interactive workshop followed by an appointment scheduling assistance from a promotor. Workshop participants were Latino adults (males and females) aged 50 to 75 years who were not up-to-date with CRC screening guidelines. We conducted interviews before and 6 to 9 months after the workshop to assess program outcomes. Results. Of the 177 participants included, 118 reported completing the CRC screening test (66.7%) by 6 to 9 months postintervention. We observed baseline to 6- to 9-month increase in CRC knowledge and lower perceived barriers to obtaining CRC screening. Furthermore, the intervention was found to be feasible and acceptable. Conclusion. Results suggest that JUNTOS can be feasibly implemented in partnership with a federally qualified health center. The current study supports group-based CRC interventions in community and clinic settings.

Cultural adaptation of 'Healthy Dads, Healthy Kids' for Hispanic families: applying the ecological validity model.

BACKGROUND: Healthy Dads Healthy Kids (HDHK) is a unique lifestyle obesity intervention for fathers and children that demonstrated weight loss among the fathers and behavior change among fathers and children in Australia. The program is gender-tailored to specifically target fathers for weight loss and 5-12 year old children for obesity prevention. The aim of this formative study was to examine an Expert Panel's and Hispanic Family Panel's perceptions about the program and suggestions for the cultural adaptation of HDHK for Hispanic families in southwestern US. METHODS: Forty-four Hispanic participants (22 fathers, 13 mothers and 9 children) made up the Family Panel. They participated in 1-5 study contacts (focus groups, online survey, and/or interviews). The scripts and qualitative guides assessed participants' perceptions of the HDHK content and material using the Ecological Validity Model. Studies were conducted in English or Spanish, depending on the preference of the participant. Focus groups and interviews were audio-recorded, transcribed, translated, and thematically coded. Findings were reviewed with the Expert Panel who helped inform the cultural adaptation. RESULTS: 80% of parents were foreign-born, 57% spoke only Spanish at home, and 60% did not graduate from high school. Several themes emerged to inform the cultural adaptation of the program. Parents agreed with the HDHK goals and recommended the program place greater emphasis on parenting and limiting children's screen time. Some mothers and fathers wanted greater mother engagement. Weekly videos and a Facebook group emerged as favorite alternative options to engage mothers. Greater promotion of familism (inclusion and impact on whole family) was recommended for the program goals and activities. Gender roles for mothers and fathers, and differences in how fathers interact with male and female children, emerged and should be considered in program activities. Several barriers to father engagement surfaced, including lack of time due to work schedules, physically demanding jobs, concerns of caring for children without mother, fathers' current fitness/weight, and lack of knowledge of how to eat more healthfully. The reading level of the HDHK materials was too high for some parents. CONCLUSION: Findings from these formative qualitative studies informed the cultural adaptation of HDHK for Hispanic families, to account for literacy level, cultural values, and barriers to participation and engagement.

Text messaging and brief phone calls for weight loss in overweight and obese English- and Spanish-speaking adults: A 1-year, parallel-group, randomized controlled trial.

BACKGROUND: Weight loss interventions based solely on text messaging (short message service [SMS]) have been shown to be modestly effective for short periods of time and in some populations, but limited evidence is available for positive longer-term outcomes and for efficacy in Hispanic populations. Also, little is known about the comparative efficacy of weight loss interventions that use SMS coupled with brief, technology-mediated contact with health coaches, an important issue when considering the scalability and cost of interventions. We examined the efficacy of a 1-year intervention designed to reduce weight among overweight and obese English- and Spanish-speaking adults via SMS alone (ConTxt) or in combination with brief, monthly health-coaching calls. ConTxt offered 2-4 SMS/day that were personalized, tailored, and interactive. Content was theory- and evidence-based and focused on reducing energy intake and increasing energy expenditure. Monthly health-coaching calls (5-10 minutes' duration) focused on goal-setting, identifying barriers to achieving goals, and self-monitoring. METHODS AND FINDINGS: English- and Spanish-speaking adults were recruited from October 2011 to March 2013. A total of 298 overweight (body mass index [BMI] 27.0 to 39.9 kg/m2) adults (aged 21-60 years; 77% female; 41% Hispanic; 21% primarily Spanish speaking; 44% college graduates or higher; 22% unemployed) were randomly assigned (1:1) to receive either ConTxt only (n = 101), ConTxt plus health-coaching calls (n = 96), or standard print materials on weight reduction (control group, n = 101). We used computer-based permuted-block randomization with block sizes of three or six, stratified by sex and Spanish-speaking status. Participants, study staff, and investigators were masked until the intervention was assigned. The primary outcome was objectively measured percent of weight loss from baseline at 12 months. Differences between groups were evaluated using linear mixed-effects regression within an intention-to-treat framework. A total of 261 (87.2%) and 253 (84.9%) participants completed 6- and 12-month visits, respectively. Loss to follow-up did not differ by study group. Mean (95% confidence intervals [CIs]) percent weight loss at 12 months was -0.61 (-1.99 to 0.77) in the control group, -1.68 (-3.08 to -0.27) in ConTxt only, and -3.63 (-5.05 to -2.81) in ConTxt plus health-coaching calls. At 12 months, mean (95% CI) percent weight loss, adjusted for baseline BMI, was significantly different between ConTxt plus health-coaching calls and the control group (-3.0 [-4.99 to -1.04], p = 0.003) but not between the ConTxt-only and the control group (-1.07 [-3.05 to 0.92], p = 0.291). Differences between ConTxt plus health-coaching calls and ConTxt only were not significant (-1.95 [-3.96 to 0.06], p = 0.057). These findings were consistent across other weight-related secondary outcomes, including changes in absolute weight, BMI, and percent body fat at 12 months. Exploratory subgroup analyses suggested that Spanish speakers responded more favorably to ConTxt plus health-coaching calls than English speakers (Spanish contrast: -7.90 [-11.94 to -3.86], p < 0.001; English contrast: -1.82 [-4.03 to 0.39], p = 0.107). Limitations include the unblinded delivery of the intervention and recruitment of a predominantly female sample from a single site. CONCLUSIONS: A 1-year intervention that delivered theory- and evidence-based weight loss content via daily personalized, tailored, and interactive SMS was most effective when combined with brief, monthly phone calls. TRIAL REGISTRATION: ClinicalTrials.gov NCT01171586.

Diagnostic colonoscopy completion after abnormal fecal immunochemical testing and quality of tests used at 8 Federally Qualified Health Centers in Southern California: Opportunities for improving screening outcomes.

BACKGROUND: The effectiveness of colorectal cancer screening with fecal immunochemical tests (FITs) of stool blood depends on high rates of colonoscopy follow-up for abnormal FITs and the use of high-quality tests. This study characterized colonoscopy referral and completion among patients with abnormal FITs and the types of FITs implemented in a sample of Southern California Federally Qualified Health Centers (FQHCs). METHODS: FQHCs in San Diego, Imperial, and Los Angeles Counties were invited to define a cohort of ≥150 consecutive patients with abnormal FITs in 2015-2016 and to provide data on sex, insurance status, diagnostic colonoscopy referrals and completion within 6 months of abnormal FITs, and the types (brands) of FITs implemented. The primary outcomes were the proportions with colonoscopy referrals and completion for all patients at each FQHC and in aggregate. RESULTS: Eight FQHCs provided data for 1229 patients with abnormal FITs; 46% were male, and 20% were uninsured. Among patients with abnormal FITs, 89% (1091 of 1229; 95% confidence interval [CI], 0.87-0.91) had a colonoscopy referral, and 44% (539 of 1229; 95% CI, 0.41-0.47) had colonoscopy completion. Across FQHCs, the range for colonoscopy referral was 73% to 96%, and the range for completion was 18% to 57%. Six of the 8 FQHCs (75%) reported FIT brands with limited data to support their effectiveness. CONCLUSIONS: In a sample of Southern California FQHCs, diagnostic colonoscopy completion after abnormal FITs was substantially below the nationally recommended benchmark to achieve 80% completion, and the use of FIT brands with limited data to support their effectiveness was high. These findings suggest a need for policies and multilevel interventions to promote diagnostic colonoscopy among individuals with abnormal FITs and the use of higher quality FITs.

Latina mothers as agents of change in children's eating habits: findings from the randomized controlled trial Entre Familia: Reflejos de Salud.

BACKGROUND: Few children consume sufficient servings of fruits and vegetables. Interventions aiming to improve children's dietary intake often target parent level factors, but limited research has examined the mediating role of parental factors on children's dietary intake. This study examined 10-month follow up data from the Entre Familia: Reflejos de Salud (Within the Family: Reflections of Health) trial to investigate (1) intervention effects on children's dietary intake, both sustained and new changes, and (2) whether changes in mothers' dietary intake, her parenting strategies, and behavioral strategies to promoting healthy eating in the home mediated changes in children's dietary intake. METHODS: Participants were 361 Mexican-origin families living in Imperial County, California. Families were randomly assigned to a 4-month dietary intervention or a delayed treatment control group. The intervention was delivered by promotoras (community health workers) via home visits and telephone calls. Assessments occurred at baseline, and 4- and 10-months post-baseline. RESULTS: At 10-months post-baseline, sustained intervention effects were observed on children's reported intake of varieties of vegetables, with differences getting larger over time. However, differential intervention effects on fast food were not sustained due to significant reductions in the control group compared with smaller changes in the intervention group. New intervention effects were observed on servings of sugar-sweetened beverages. However, the intervention continued to have no effect on children's reported fruit and vegetable servings, and varieties of fruits consumed. Mother-reported behavioral strategies to increase fiber and lower fat mediated the relationship between the intervention and children's intake of varieties of vegetables. Mothers' percent energy from fat and behavioral strategies to lower fat were mediators of children's daily servings of sugar-sweetened beverages. CONCLUSIONS: This study suggests that a promotora-led family based intervention can provide mothers with skills to promote modest changes in children's diet. Examining the parent related mechanisms of change will inform future interventions on important targets for improving children's diet. TRIAL REGISTRATION: https://clinicaltrials.gov/ . NCT02441049 .

Planned care for obesity and cardiovascular risk reduction using a stepped-down approach: A randomized-controlled trial.

Primary care-based approaches to address concurrent obesity and cardiovascular disease risk factors (CVDRFs) that begin with a high intensity intervention that is subsequently decreased (i.e., stepped-down) if weight loss is achieved have not been rigorously examined. Our study is a 20-month, single-blind randomized controlled trial at five primary care clinics in San Diego, CA, in 2013, where 262 obese adults (aged 25-70 years; 32.1% male; 59.2% white) with at least one CVDRF were enrolled into planned care for obesity and risk reduction (PCORR) using a stepped-down approach or enhanced usual care (EUC). All patients received physician recommendations for weight loss and CVDRFs. EUC patients (n = 132) received an individual session with a health educator every 4 months. PCORR patients (n = 130) received individual and group sessions (in-person, mail, telephone, and email) in three steps, characterized by less contact if success was achieved. At 20 months, 40.7%, 23.8%, and 15.4% of PCORR patients were in steps 1, 2, and 3, respectively (25.2% were lost to follow-up). PCORR resulted in a between-group difference in reduction in body weight of 6.1% [95% CI, 5.3 to 6.9] compared to EUC 2.8% [95% CI, 2.0 to 3.6] p = 0.007, with a greater reduction in BMI (35.2 [95% CI, 34.4 to 35.9] to 33.7 [95% CI, 32.9 to 34.5] kg/m2) than EUC (36.0 [95% CI, 35.3 to 36.8] to 35.1 [95% CI, 34.3 to 35.9] kg/m2), as indicated by a significant treatment by time interaction (p = 0.009). PCORR resulted in greater weight loss over 20 months than EUC. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01134029.

Exploring how bicultural and assimilated children of Mexican origin influence their Latina mothers' diet: Perspectives from mothers and children.

Social and cultural factors influence dietary intake and behaviors. Research shows that mothers consume a lower quality diet when they have a child who is assimilated to the US culture versus bicultural. The purpose of this study was to qualitatively compare how bicultural and assimilated children influenced their culturally traditional mothers' dietary intake/behaviors. Separate one-on-one interviews with 21 Mexican-origin mothers and their bicultural (n = 11) or assimilated (n = 10) children (10-13 years old) were conducted. We used framework analysis to reduce qualitative data to themes and subthemes. Data were analyzed separately and then compared between mothers of bicultural versus assimilated children. Mothers of bicultural children reported typically having an easier time consuming a better quality diet than mothers of assimilated children. For example, although all children requested non-traditional foods, bicultural children were typically more accepting of their mothers preparing traditional healthier foods than assimilated children. Furthermore, mothers believed their children's food preferences both influenced and were influenced by their own feeding styles. Mothers of bicultural children described using more "Mexican" (i.e., authoritative) feeding styles that they believed shaped their children's palate into preferring traditional foods. Mothers of assimilated children explained that their children's preference for non-traditional foods resulted in their use of more permissive or indulgent feeding styles. Longitudinal research is needed to test and confirm the directionality between feeding styles and child's food preferences. Interventions may need to consider the reciprocal influences between mothers' feeding styles, children's food preferences, and how children influence their mothers' dietary intake/behavior.
