Family-Based Motivational Interviewing and Resource Mobilization to Prevent Obesity: Living Well Together Trial.

OBJECTIVE: Test an obesity intervention for families with low incomes. METHODS: A total of 208 families were included (a parent with a body mass index [BMI] ≥ 30 and a child aged 6-12 years). A 12-month randomized controlled trial combining family health coaching (motivational interviewing) and connection to community resources. Comparison group: referrals for basic needs, written educational materials. Questionnaires, accelerometry, and anthropometrics. Intention-to-treat analysis of change in outcomes. Two-sided t test with multiple imputation. RESULTS: Parents were 95% female, 31% Black, and 27% Hispanic. Children had a mean BMI-Z score of 1.15. Primary outcomes did not differ between groups at 12 months. Both groups significantly (P < 0.05) improved on the Family Nutrition and Physical Activity Scale for behaviors related to childhood obesity (mean ± SE: comparison, 2.8 ± 1.0; intervention, 2.2 ± 0.9), increased child sedentary activity (comparison, 32.5 ± 12.1; intervention, 39.9 ± 12.4 min/d), and decreased child moderate-vigorous physical activity (comparison, -9.6 ± 3.3; intervention -7.0 ± 3.0 min/d). Parents had no change in BMI. CONCLUSIONS AND IMPLICATIONS: We successfully embedded screening and referral to address social needs within an obesity intervention. The coaching intervention did not provide additional benefits. Future research could explore ways to make these interventions more accessible, valuable, and effective for families.

The Association Between State Characteristics and Latinx People's Treated Hypertension in Established and New Latinx Destination States: A Multilevel Analysis.

This study sought to quantify the contributions of state-level factors including income inequality, state's legislature political control, and Medicaid expansion in new and established Latinx destination states on Latinx individuals' treated hypertension. Mixed-effects logistic regression analyses were conducted to analyze 2017 Behavioral Risk Factor Surveillance System data from 7524 Latinx adults nested within 39 states. Overall, 70% reported being pharmacologically treated for hypertension, and 66% resided in established destination states. Compared with Latinx people in established destination states, Latinx people in new destinations had lower odds of having treated hypertension (odds ratio [OR] = 0.72, 95% CI = 0.54-0.95). Within established Latinx destinations, the odds of treated hypertension were lower in states where legislatures expanded Medicaid than in states that did not expand Medicaid (OR = 0.84, 95% CI = 0.79-0.89). However, after controlling for the effects of individual-level factors, this association was no longer statistically significant. In new Latinx destination states, Medicaid expansion, legislatures' political control, and income inequality were not associated with treated hypertension. The study results highlight the importance of considering both individual- and state-level factors, as the interplay of such factors could hinder the successful implementation of cardiovascular risk reduction interventions.

Prospective associations of neighborhood healthy food access and walkability with weight status in a regional pediatric health system.

BACKGROUND: Most neighborhood food and activity related environment research in children has been cross-sectional. A better understanding of prospective associations between these neighborhood environment factors and children's weight status can provide stronger evidence for informing interventions and policy. This study examined associations of baseline and changes in neighborhood healthy food access and walkability with changes in children's weight status over 5 years. METHODS: Height, weight, and home address were obtained for 4,493 children (> 75% were Black or Latinx) from primary care visits within a large pediatric health system. Eligible participants were those who had measures collected during two time periods (2012-2014 [Time 1] and 2017-2019 [Time 2]). Data were integrated with census tract-level healthy food access and walkability data. Children who moved residences between the time periods were considered 'movers' (N = 1052; 23.4%). Mixed-effects models, accounting for nesting of children within census tracts, were conducted to model associations of baseline and changes in the neighborhood environment variables with Time 2 weight status (BMIz and overweight or obese vs. healthy weight). Models adjusted for weight status and child and neighborhood sociodemographics at baseline. RESULTS: Children living in a neighborhood with [ample] healthy food access at Time 1 had a lower BMIz at Time 2, regardless of mover status. A decrease in healthy food access was not significantly associated with children's weight status at Time 2. Baseline walkability and improvements in walkability were associated with a lower BMIz at Time 2, regardless of mover status. CONCLUSIONS: Findings provide evidence that residing in a neighborhood with healthy food access and walkability may support a healthy weight trajectory in children. Findings on changes in the neighborhood environment suggested that improved walkability in the neighborhood may support children's healthy weight. The greater and more consistent findings among movers may be due to movers experiencing greater changes in neighborhood features than the changes that typically occur within a neighborhood over a short period of time. Future research is needed to investigate more robust environmental changes to neighborhoods.

Value of cognitive interviewing in the development of the weight stigma in healthcare inventory.

BACKGROUND: Despite the detrimental effects of weight stigma in healthcare, there is no widely validated measure comprehensively examining such experiences. OBJECTIVE: We aimed to develop and pilot test an inventory to measure patient experiences of weight stigma in healthcare, and to ensure our items were easily understood. PATIENT INVOLVEMENT: During our iterative design process, patients assessed whether our inventory items were easy to understand and we included an open-ended comments question. METHODS: We compiled items from pre-existing tools assessing experiences of weight stigma in healthcare, and developed our own novel items. We conducted field pre-testing with a convenience sample of 48 patients at a Midwest academic internal medicine clinic. We utilized an iterative design process whereby respondents provided feedback on our inventory, we analyzed the data and made revisions, and then repeated the cycle. RESULTS: Respondents found some of the language in our items confusing; expressed reluctance to speculate on the motivations of healthcare providers; had difficulty with "double-barreled" questions; found some questions vague; and expressed the desire to have weight addressed in clinical encounters neither too much nor too infrequently. We altered items appropriately, and in subsequent rounds of data collection they were easier to understand. DISCUSSION: Patients found many common weight stigma survey items and some of our novel items confusing. Our modified inventory reduces patient confusion and enhances data quality. PRACTICAL VALUE: Our study demonstrates the value of cognitive interviewing. Furthermore, the WSHCI will be a useful tool for clinicians and research teams seeking to measure weight stigma in healthcare but first needs to be validated in a larger sample. FUNDING: This study was supported by the Physician Scientist Training Program, Diabetes Center T32 (DK112751), and the Clinical and Translational Science Award grant funded from the National Institutes of Health (UL1TR002537).

Identifying the Social Determinants of Treated Hypertension in New and Established Latino Destination States.

Little is known about the influence of social and environmental contexts on Latino hypertension-related disparities. This study examined the influence of social determinants of cardiovascular health on medically treated hypertension, contrasting established vs. new Latino destination states. Logistic regression models were fitted to analyze 2017 Behavioral Risk Factors Surveillance Survey data from 8,999 Latinos. Overall, 70.4% indicated having treated hypertension. History of diabetes (OR = 2.60) and access to healthcare (OR = 2.38) were associated with treated hypertension, regardless of destination state. In established destinations, Latinos who graduated high school (OR = 1.19) or attended college (OR = 1.32) had higher odds of treated hypertension; whereas those who completed college were less likely to have treated hypertension (OR = 0.80). In contrast, in both new and non-destination states, the odds of treated hypertension were consistently lower across levels of educational attainment. Results highlight the need for cardiovascular-risk reduction interventions to incorporate the social and environmental context in the development process.

Obesity treatment initiation, retention, and outcomes in the Veterans Affairs MOVE! Program among rural and urban veterans.

Objective: Rural veterans have high obesity rates. Yet, little is known about this population's engagement with the Veterans Affairs (VA) weight management program (MOVE!). The study objective is to determine whether MOVE! enrollment, anti-obesity medication use, bariatric surgery use, retention, and outcomes differ by rurality for veterans with severe obesity. Methods: This is a retrospective cohort study using Veterans Health Administration patient databases, including VA patients with severe obesity during 2015-2017. Patients were categorized using Rural-Urban Commuting Area codes. Primary outcomes included proportion of patients and risk-adjusted likelihood of initiating VA MOVE!, anti-obesity medication, or bariatric surgery and risk-adjusted highly rural|Hazard Ratio (HR) of any obesity treatment. Secondary outcomes included treatment retention (≥12 weeks) and successful weight loss (5%) among patients initiating MOVE!, and risk-adjusted odds of retention and successful weight loss. Results: Among 640,555 eligible veterans, risk-adjusted relative likelihood of MOVE! treatment was significantly lower for rural and HR veterans (HR = 0.83, HR = 0.67, respectively). Initiation rates of anti-obesity medication use were significantly lower as well, whereas bariatric surgery rates, retention, and successful weight loss did not differ. Conclusions: Overall treatment rates with MOVE!, bariatric surgery, and anti-obesity medications remain low. Rural veterans are less likely to enroll in MOVE! and less likely to receive anti-obesity medications than urban veterans.

Resource mobilization combined with motivational interviewing to promote healthy behaviors and healthy weight in low-income families: An intervention feasibility study.

Objectives: This non-randomized pilot trial examined the feasibility and acceptability of an intervention for low-income families with one parent with obesity, glucose intolerance and/or diabetes. Methods: The 12-month intervention combined health coaching using motivational interviewing to promote lifestyle behavior change and community resource mobilization to assist with basic needs plus diet quality and physical activity. Outcome measures included process measures, open-ended questions, and the Family Nutrition and Physical Activity scale. Results: Forty-five families completed an average of 2.1 health coach in-person visits, including 15 families lost to follow-up. Parents who stayed in the intervention reported the intervention was helpful. Some families and the health coach had difficulties contacting one another, and some of these families reported they would have liked more sessions with the coach. The Family Nutrition and Physical Activity scores improved significantly for all children (6 months: 2.9; p < .01; 12 months: 3.2; p < .05) and at 6 months for index children (6 months: 3.5; p < .01; 12 months: 2.9; p = .09). There was variation in the FNPA and other outcome changes between families. Conclusion: This intervention was feasible in terms of recruitment and delivery of family sessions and community referrals and acceptable to participants, but maintaining contact with participants was difficult. Findings warrant improvements to help retention and logistical aspects of communication between families and coaches and testing in a randomized, controlled trial.

A randomized controlled trial of a community-based obesity intervention utilizing motivational interviewing and community resource mobilization for low-income families: Study protocol and baseline characteristics.

Low-income, racially diverse families with one parent with obesity are at high risk for child obesity. Effective approaches to promote healthy behaviors and prevent additional weight gain in family members are needed. Motivational interviewing (MI) may assist families to engage, identify motivations for change and establish goals. However, families with limited resources face other barriers to goal achievement that may be addressed through connection with community organizations. This paper describes a unique protocol combining MI and community connection. This randomized controlled trial includes low-income families with one parent with obesity and at least one child aged 6 to 12 years. Families in the intervention group receive an innovative, 12-month intervention combining health coaching using MI to promote lifestyle behavior change goals and community resource mobilization to assist with basic needs and resources to aid goals. The study protocol is modeled on community-based participatory research principles. Data is collected at baseline, 6 months, 12 months, and 18 months include questionnaires, body measurements, and accelerometer data. For adults, primary outcomes are Body Mass Index (BMI), minutes of moderate to vigorous physical activity (MVPA), and hours of sedentary time per day. For children, primary outcomes are sedentary time, MVPA, and the Family Nutrition and Physical Activity Score. From this hard-to-reach population, 236 diverse families were recruited. If the study is deemed effective, it has the potential to demonstrate that the combination of MI, resource mobilization, and utilization of existing community organizations is a sustainable model to assist families at risk for obesity.

Diet and physical activity changes among low-income families: perspectives of mothers and their children.

Purpose: The current study explored how mothers and their children influence each other's diet and physical activity. Methods: We conducted semi-structured interviews with women with diabetes and their children (N = 18) from eight low-income families. Results: Two approaches to changes emerged: collaborative and non-collaborative. Families using collaborative approaches believed they could sustain positive changes through accepting family changes, encouragement, abstaining from buying certain foods, modelling and compromise. Within families using non-collaborative approaches, some challenges included using more individualistic approaches and poor communication. Lack of information and resource constraints challenged all families. Conclusion: Interventions should reinforce family collaborative approaches and teach skills for families to work together towards a healthier lifestyle.

Patient Engagement and Attitudes Toward Using the Electronic Medical Record for Medical Research: The 2015 Greater Plains Collaborative Health and Medical Research Family Survey.

BACKGROUND: Electronic health records (EHRs) are ubiquitous. Yet little is known about the use of EHRs for prospective research purposes, and even less is known about patient perspectives regarding the use of their EHR for research. OBJECTIVE: This paper reports results from the initial obesity project from the Greater Plains Collaborative that is part of the Patient-Centered Outcomes Research Institute's National Patient-Centered Clinical Research Network (PCORNet). The purpose of the project was to (1) assess the ability to recruit samples of adults of child-rearing age using the EHR; (2) prospectively assess the willingness of adults of child-rearing age to participate in research, and their willingness (if parents) to have their children participate in medical research; and (3) to assess their views regarding the use of their EHRs for research. METHODS: The EHRs of 10 Midwestern academic medical centers were used to select patients. Patients completed a survey that was designed to assess patient willingness to participate in research and their thoughts about the use of their EHR data for research. The survey included questions regarding interest in medical research, as well as basic demographic and health information. A variety of contact methods were used. RESULTS: A cohort of 54,269 patients was created, and 3139 (5.78%) patients responded. Completers were more likely to be female (53.84%) and white (85.84%). These and other factors differed significantly by site. Respondents were overwhelmingly positive (83.9%) about using EHRs for research. CONCLUSIONS: EHRs are an important resource for engaging patients in research, and our respondents concurred. The primary limitation of this work was a very low response rate, which varied by the method of contact, geographic location, and respondent characteristics. The primary strength of this work was the ability to ascertain the clinically observed characteristics of nonrespondents and respondents to determine factors that may contribute to participation, and to allow for the derivation of reliable study estimates for weighting responses and oversampling of difficult-to-reach subpopulations. These data suggest that EHRs are a promising new and effective tool for patient-engaged health research.

Is There a Spillover Effect of Targeted Dietary Change on Untargeted Health Behaviors? Evidence From a Dietary Modification Trial.

Background. The gateway behavior hypothesis posits that change in a health behavior targeted for modification may promote positive changes in other untargeted health behaviors; however, previous studies have shown inconsistent results. Aims. To examine the patterns and predictors of change in untargeted health behaviors in a large health behavior change trial. Method. Using repeated-measures latent class analysis, this study explored patterns of change in untargeted physical activity, alcohol consumption, and smoking behavior during the first year of the Women's Health Initiative dietary modification trial that targeted total fat reduction to 20% kcal and targeted increased fruit and vegetable intake. Participants were healthy postmenopausal women who were randomly assigned to either the low-fat dietary change intervention (n = 8,193) or a control (n = 12,187) arm. Results. Although there were increases in untargeted physical activity and decreases in alcohol consumption and smoking in the first year, these changes were not consistently associated with study arm. Moreover, although the results of the repeated-measures latent class analysis identified three unique subgroups of participants with similar patterns of untargeted health behaviors, none of the subgroups showed substantial change in the probability of engagement in any of the behaviors over 1 year, and the study arms had nearly identical latent class solutions. Discussion and Conclusion. These findings suggest that the dietary intervention did not act as a gateway behavior for change in the untargeted behaviors and that researchers interested in changing multiple health behaviors may need to deliberately target additional behaviors.

Active Ottumwa: Adapting Evidence-Based Recommendations to Promote Physical Activity in a Micropolitan New Destination Community.

Background: Evidence-based interventions have been developed and tested to promote physical activity, but fewer studies have focused on identifying effective intervention strategies for mid-size rural communities, especially new immigrant destinations. We report here on the design and implementation of Active Ottumwa, a community-wide intervention using a lay health advisor approach to increase physical activity in a micropolitan new destination community in the rural state of Iowa. Methods: The Active Ottumwa study is part of a community-academic partnership in Ottumwa, IA. Evidence-based strategies recommended by the Community Guide for Preventive Services guided study implementation and included behavioral and social, campaign and informational, and environmental and policy approaches. Evaluation methods for this study are multi-faceted and include a cross-sectional community survey, longitudinal cohort assessment, observational data, key informant interviews, and project records. Results: We are currently in our second year of intervention implementation, with 45 lay health advisors (termed physical activity leaders here) trained to carry out behavioral and social intervention approaches, including walking groups, tai chi, and yoga. We have completed a communication and informational campaign utilizing five channels. Our longitudinal cohort has been recruited, with baseline and 12-month data collection completed. Conclusions: This study will assess the effectiveness and impact of a community-wide intervention to support physical activity.

Calibration of the global physical activity questionnaire to Accelerometry measured physical activity and sedentary behavior.

BACKGROUND: Self-report questionnaires are a valuable method of physical activity measurement in public health research; however, accuracy is often lacking. The purpose of this study is to improve the validity of the Global Physical Activity Questionnaire by calibrating it to 7 days of accelerometer measured physical activity and sedentary behavior. METHODS: Participants (n = 108) wore an ActiGraph GT9X Link on their non-dominant wrist for 7 days. Following the accelerometer wear period, participants completed a telephone Global Physical Activity Questionnaire with a research assistant. Data were split into training and testing samples, and multivariable linear regression models built using functions of the GPAQ self-report data to predict ActiGraph measured physical activity and sedentary behavior. Models were evaluated with the testing sample and an independent validation sample (n = 120) using Mean Squared Prediction Errors. RESULTS: The prediction models utilized sedentary behavior, and moderate- and vigorous-intensity physical activity self-reported scores from the questionnaire, and participant age. Transformations of each variable, as well as break point analysis were considered. Prediction errors were reduced by 77.7-80.6% for sedentary behavior and 61.3-98.6% for physical activity by using the multivariable linear regression models over raw questionnaire scores. CONCLUSIONS: This research demonstrates the utility of calibrating self-report questionnaire data to objective measures to improve estimates of physical activity and sedentary behavior. It provides an understanding of the divide between objective and subjective measures, and provides a means to utilize the two methods as a unified measure.

College Cafeteria Signage Increases Water Intake but Water Position on the Soda Dispenser Encourages More Soda Consumption.

OBJECTIVES: To evaluate the effects of improved water location visibility and water dispenser position on the soda dispenser on undergraduate students' beverage choices. METHODS: Two focus groups with pilot intervention surveys before and after, adding a small sign above the soda dispensers' water button for 6 weeks in a large US university's all-you-can-eat, prepaid dining hall (measured with chi-square tests and logistic and ordinal logistic regression). RESULTS: Focus groups included 15 students. Survey participants included 357 students before and 301 after the intervention. After the intervention, more students reported ever having drunk water with the meal (66.4% to 77.0%; P = .003) and water consumption frequency increased (P = .005). Postintervention, the odds of drinking water increased by 1.57. Preference for other drinks was the main reason for not drinking water. A total of 59% of students had ever changed their preference from water to soda. CONCLUSIONS AND IMPLICATIONS: The clear indication of the water's location increased students' reported water consumption. Further investigation is needed into how a non-independent water dispenser influences students' beverage choice. Clearly labeled, independent water dispensers are recommended.

Healthy Concessions: High School Students' Responses to Healthy Concession Stand Changes.

BACKGROUND: A previous sales data analysis demonstrated success in selling healthier items at a concession stand. Questions remained regarding student satisfaction and whether the intervention reached non-health-conscious students. METHODS: Cross-sectional anonymous samples of students at a large midwestern high school were surveyed before and after an intervention improved the number of healthier items available at the concession stand. RESULTS: The survey was completed by 301 students preintervention and 314 students postintervention. Satisfaction remained good (3.7 preintervention and 3.6 postintervention). Satisfaction with the variety and taste of foods increased. We compared students who felt having healthy items were important at the concessions to those who did not. Overall satisfaction with concessions did not differ between groups. The latter group (healthy items not important) reported improved satisfaction with food variety (2.8 to 3.1, p = .02) and the former reported improved satisfaction with healthy foods (2.5 to 2.9, p = .03) and overall taste (3.2 to 3.4, p = .02). Of the healthy items not important students 76% reported purchasing at least 1 new healthier food. CONCLUSIONS: Adding healthier foods to school concession stands has positive effects on student satisfaction, sales, and reaches all students whether or not they care about having healthy items available.

Marriage and parenthood in relation to obesogenic neighborhood trajectories: The CARDIA study.

Marriage and parenthood are associated with weight gain and residential mobility. Little is known about how obesity-relevant environmental contexts differ according to family structure. We estimated trajectories of neighborhood poverty, population density, and density of fast food restaurants, supermarkets, and commercial and public physical activity facilities for adults from a biracial cohort (CARDIA, n=4,174, aged 25-50) over 13 years (1992-93 through 2005-06) using latent growth curve analysis. We estimated associations of marriage, parenthood, and race with the observed neighborhood trajectories. Married participants tended to live in neighborhoods with lower poverty, population density, and availability of all types of food and physical activity amenities. Parenthood was similarly but less consistently related to neighborhood characteristics. Marriage and parenthood were more strongly related to neighborhood trajectories in whites (versus blacks), who, in prior studies, exhibit weaker associations between neighborhood characteristics and health. Greater understanding of how interactive family and neighborhood environments contribute to healthy living is needed.

Concession stand makeovers: a pilot study of offering healthy foods at high school concession stands.

BACKGROUND: Concession stands at high school events are exempt from the US Department of Agriculture regulations for school foods. Concessions are generally stocked with unhealthy foods since healthy foods are believed to have lower sales and profit margins. METHODS: Concession stand sales for two seasons of high school fall sports in Muscatine, Iowa were compared. In between seasons, two types of changes were made: (i) addition of new healthier concession options and (ii) substitution of healthier ingredients (less saturated fat, no trans fat). Satisfaction surveys of students and parents were conducted before and after the changes. Data were collected in 2008 and 2009 and analyzed in 2012-13. RESULTS: Revenue per game was similar between years, even with the introduction of healthier items and ingredient changes. In 2009, the new healthy foods comprised 9.2% of total revenue and sales of some new items increased with each game. The 'healthy makeover' had no influence on student satisfaction but it improved parent satisfaction (P < 0.001). CONCLUSIONS: This compelling test of concept shows that offering healthier items can be good for both sales and satisfaction. While this study was conducted with concession stands, the principles can be carried over into other food retail settings.

Weight gain among men and women who have a child enter their home.

Parenthood is associated with decreased physical activity and dietary changes. Previously, mothers have been the focus of studies examining the influence of children on parents' body mass index (BMI), largely ignoring whether parenting affects fathers. This study assessed weight gain in mothers and fathers (by birth or other), using longitudinal repeated-measures models to assess BMI changes over time; parents were compared with nonparents. Data were from the Coronary Artery Risk Development in Young Adults cohort study and included 2,881 black and white adults, ages 18 to 30 years, without children at baseline (1985-1986), and from four urban locations. At each time point (years 2, 5, and 7), changes in BMI from baseline were analyzed, comparing those who had their children in their household at that time point (parents) and those without children (nonparents). The "child effect" is the mean difference in BMI change in parents compared with nonparents. In fathers, overall, the child effect was not significant (black males: 0.30; P=0.09; white males: 0.03; P=0.77). Among black men, however, interactions between age and parental status were significant (P=0.02). Black men who were aged 18 to 24 years at baseline and became fathers during the next 7 years demonstrated a significant child effect, gaining an average of 0.68 more in BMI than nonfathers (P=0.003). Mothers of both races demonstrated the child effect; for blacks it was 0.65 (P=0.003) and for whites it was 1.12 (P≤0.001). These data reveal that becoming a parent can affect the BMI of some adults and suggest that obesity-prevention interventions for children and adult-focused healthy-lifestyle interventions could have additional impact through a family focus targeting both parent and child outcomes.
