ABSTRACT

Background: Few studies have examined both parent and child preferences regarding family-based weight management programs (WMPs) delivered in primary care settings, especially among racial minority populations. The purpose of this study was to determine the perceptions that parents and their children/adolescents have about the components that should be included in a family-based WMP and to identify perceived preferences, benefits, and/or barriers to participation. Methods: A sample of 60 participants (30 parents and 30 children/adolescents) participated in 1 of 5 separate structured focus groups, using probing questions and the nominal group technique (NGT). Parents reported demographics for themselves and their children/adolescents. Themes from probing questions were identified using thematic analysis. Results: Parents were primarily African American (93%) and diverse in income. NGT sessions revealed that parents across all groups perceived that education on healthy eating, parental involvement, and effective program leaders are most important and have the greatest impact, while parental involvement was perceived as the easiest method to implement in a family-based WMP for childhood obesity. Children/adolescents perceived that education on healthy eating and exercise would have the greatest impact, while healthy eating and meal plans were perceived as the easiest methods to implement with a family. Parents and children/adolescents also identified improved psychological well-being (eg, decreased bullying, increased self-esteem, and motivation) as a desired program outcome. Conclusion: Parents and their children/adolescents highlighted the importance of physical and psychological health as targets in treatment. Feedback from patients can inform the design and implementation of family-based WMPs delivered in primary care settings.

ABSTRACT

BACKGROUND: Less than one-third of women gain an appropriate amount of weight during pregnancy, which can influence the long-term health of both the mother and the child. Economically disadvantaged women are the most vulnerable to maternal obesity, excessive weight gain during pregnancy, and poor birth outcomes. Effective and scalable health care strategies to promote healthy weight gain during pregnancy specifically tailored for these women are lacking. OBJECTIVE: This paper presents the design and protocol of a biphasic, community-based eHealth trial, SmartMoms in WIC, to increase the adherence to healthy gestational weight gain (GWG) recommendations in low-income mothers receiving women, infant, and children (WIC) benefits. METHODS: Phase 1 of the trial included using feedback from WIC mothers and staff and participants from 2 community peer advisory groups to adapt an existing eHealth gestational weight management intervention to meet the needs of women receiving WIC benefits. The health curriculum, the format of delivery, and incentive strategies were adapted to be culturally relevant and at an appropriate level of health literacy. Phase 2 included a pragmatic randomized controlled trial across the 9 health care regions in Louisiana with the goal of enrolling 432 women. The SmartMoms in WIC intervention is an intensive 24-week behavioral intervention, which includes nutrition education and exercise strategies, and provides the technology to assist with weight management, delivered through a professionally produced website application. RESULTS: Phase 1 of this trial was completed in July 2019, and recruitment for phase 2 began immediately thereafter. All data are anticipated to be collected by Spring 2023. CONCLUSIONS: The SmartMoms in WIC curriculum was methodically developed using feedback from community-based peer advisory groups to create a culturally relevant, mobile behavioral intervention for mothers receiving WIC benefits. The randomized clinical trial is underway to test the effectiveness of a sustainable eHealth program on the incidence rates of appropriate GWG. SmartMoms in WIC may be able to offer an innovative, cost-effective, and scalable solution for GWG management in women served by WIC.

ABSTRACT

BACKGROUND: African American adults experience a high prevalence of obesity and its associated comorbidities, including diabetes. Church-based interventions have been shown to be effective in decreasing weight in this population. mHealth interventions can address two needs for obesity treatment in this community, including enhancing weight loss and providing wide dissemination. OBJECTIVE: This study aimed to assess the feasibility and efficacy of a church-based weight loss intervention that incorporates mHealth technology. METHODS: In this study, 8 churches (n=97) were randomly assigned to the intervention or delayed intervention condition (control group). We recruited participants through their respective church. Volunteer church members were trained by study staff to deliver the 10-session, 6-month intervention. Participants in the intervention group attended group sessions and received automated short message service (SMS) text messages designed to reinforce behavioral strategies. Conversely, participants in the delayed intervention condition received SMS text messages related to health conditions relevant for African American adults. We obtained measures of body composition, blood pressure, blood glucose, and cholesterol. RESULTS: We successfully recruited 97 African American adults, with a mean age of 56.0 (SE 10.3) years and a mean body mass index of 38.6 (SE 6.4) kg/m2 (89/97, 91.8% females), who attended the churches that were randomized to the intervention (n=68) or control (n=29) condition. Of these, 74.2% (72/97) of the participants (47/68, 69.1% intervention; 25/29, 86.2% delayed intervention) completed the 6-month assessment. The average intervention group attendance was 55%. There was a significant difference in weight loss (P=.04) between participants in the intervention (-1.5 (SE 0.5) kg) and control (0.11 (SE 0.6) kg) groups. Among participants in the intervention group, the correlation between the number of SMS text messages sent and the percent body fat loss was r=.3 with P=.04. The participants reported high satisfaction with the automated SMS text messages. CONCLUSIONS: Automated SMS text messages were well-received by participants, suggesting that more enhanced mHealth technologies are a viable option for interventions targeting African American adults.

ABSTRACT

BACKGROUND: Heart failure (HF) is an incurable and frequently progressive disease. Symptoms of HF may impair the ability of patients to perform daily living activities. As HF progresses, patients typically increase their reliance on caregivers. The purpose of this study was to determine what roles patients and caregivers perceive and desire for themselves in managing HF and to compare and contrast these roles with those perceived by healthcare providers. METHODS: A purposive sample (60 patients, 22 caregivers, and 11 healthcare providers) was enrolled in the study. Patients and caregivers individually participated in semistructured interviews, and healthcare providers participated in 1 of 2 focus groups. RESULTS: Four key themes evolved from interviews with patients and caregivers-education on disease specifics, guidance to enhance quality of life, learning to cope with HF, and future outlook and care decisions-that may guide the development of caregiver interventions in HF. Healthcare providers in both structured focus groups regardless of rank order selected knowledge is powerful, adherence to treatment plan, and compliance with medication as the top 3 issues likely to have the greatest impact, and they identified education on the disease (knowledge is powerful) as the easiest strategy to implement for patients and caregivers in the management of HF. CONCLUSION: Interventions among caregivers of patients with HF are needed and should focus on education in family structures, family functioning, and skills training in family assessment and engagement.

ABSTRACT

OBJECTIVE: This study examined how well healthcare providers perceive and understand their patients' health beliefs and values compared to patients' actual beliefs, and to determine if communication relationships maybe improved as a result of healthcare providers' understanding of their patients' illness from their perspective. METHODS: A total of 61 participants (7 healthcare providers and 54 patients) were enrolled in the study. Healthcare providers and patients individually completed survey instruments and each participated in a structured focus group. RESULTS: Healthcare provider and patient differences revealed that patients perceived greater meaning of their illness (p = 0.038), and a greater preference for partnership (p = 0.026) compared to providers. The three qualitative themes most important for understanding patients' health beliefs and values as perceived by healthcare providers were education, trust, and culture. Educating patients was perceived as having the greatest impact and also the easiest method to implement to foster providers' understanding, with at least one patient focus group in agreement of same. Likewise, three themes were derived from patients' perspectives as relatively more important in understanding providers' beliefs and values; bidirectional communication, comprehensive treatment, and discipline. Overwhelmingly, bidirectional communication was perceived as a critical factor as having the greatest impact and may also be easiest to implement according to these patients. CONCLUSION: When patients and healthcare providers listen and communicate with each other, they are likely to develop a shared understanding that may improve future decision making and quality of care patients receive.

ABSTRACT

BACKGROUND: Primary care is a key component of medical care delivery and has a role to play in reducing obesity in the United States. The purpose of this study was to explore attitudes and perceptions about obesity in low-income primary care patients and to identify preferences for weight management interventions from the patient and healthcare provider perspectives. METHODS: A convenience sample of 28 patients and 6 healthcare providers from across the state of Louisiana participated in 1 of 5 structured focus groups. Demographic information was collected from both the patients and healthcare providers using survey instruments. RESULTS: Patients and healthcare providers were more similar than dissimilar in their perceptions of obesity in that both groups selected referral to a nutritionist, use of medication, and prescribed exercise as the top 3 strategies that would have the greatest impact on losing weight. Referral to a nutritionist was selected as the easiest strategy to implement. CONCLUSION: Receiving feedback from both patients and healthcare providers gives researchers the opportunity to acquire useful knowledge that may be beneficial in designing and conducting interventions suitable for patients desiring to lose weight, especially those in primary care settings.

ABSTRACT

Physical activity among African Americans (AA) is low; effective intervention strategies are needed. Community-based settings are useful for delivering health-related interventions in racial/ethnic minority communities. This article describes strategies used to recruit churches for participation in a 22-month intervention designed to increase physical activity levels in AA women. Initial recruitment efforts, led by AA study staff, included direct mailers, phone calls, and in-person meetings with church representatives. After 10 months, only five churches were enrolled. Seven community members with existing partnerships/contacts in the faith community were subsequently hired and an additional 26 churches were enrolled within 6 months. Overall response rate was 45%, and churches required 3.5 ± 3.0 months of multiple contacts prior to enrollment. The main primary contacts within churches were individuals with personal interest in the program and pastors. Prior relationship between the research team and churches did not appear to influence church enrollment as much as community member recruiters. The current study identifies several potential strategies that may be useful for increasing success in efforts to recruit AA churches into studies. Additional research is warranted that tests and compares a variety of recruitment strategies to determine the most successful strategies for recruitment in different populations.

ABSTRACT

Preventing weight gain rather than treating recognized obesity is an important economic and public health response to the growing levels of obesity nationwide. Community centers offer potential sites for community health promotion programs targeting African Americans. In this article, results from a pilot health promotion program at a community center are reported. The purpose of this 12-month pilot program was to improve diet and increase physical activity to prevent weight gain in African-American adults by delivering a lifestyle intervention. Fifty-one African-American adults were randomized into two groups: lifestyle intervention or financial counseling, and 73% completed the program. At the end of 12 months, weight for all participants was maintained from baseline to completion with no significant differences between the groups. Both lifestyle intervention and financial counseling groups were approximately 87% food secure with improvements observed in self-esteem and total quality of life scores.

ABSTRACT

The purpose of this qualitative program was to determine if a trend exists across three LSU medical homes according to patient feedback concerning their experiences within the medical home for ongoing disease management and quality healthcare; and to obtain recommendations for the most effective way to involve patients in shaping system policies, procedures, and practices consistent with patient and family-centered care principles. A total of 94 adult patients participated in either cognitive interviews (n = 45) or structured focus groups (n = 49) using the Nominal Group Technique (NGT). Exit surveys collected demographic information and feedback from patients about opportunities for their involvement in shaping medical homes. Cognitive interviews and NGT sessions both revealed some patient-perceived gratifications (i.e., friendliness and helpfulness of the clinic staff), and deficiencies (i.e., improving scheduling of appointments and reducing wait time in the clinic) within these medical homes. However, the perceived gratifications far exceeded the deficiencies found within each of three LSU medical homes.

ABSTRACT

The prevention of weight gain to address the obesity epidemic rather than weight loss involves promoting small changes in food choices and physical activity. People United to Sustain Health (PUSH) was designed to increase fruit and vegetable consumption, physical activity, and food security to prevent weight gain in rural adults. Forty-nine participants were randomized into a treatment group which received access to a "Rolling Store," nutrition education and physical activity, and a control group which received family coping classes. Forty-one (84%) of participants completed the study. At the end of 6 months, weight for all participants was maintained from baseline to completion with no significant differences between the groups. The mean fruit consumption over 6 months for the treatment group increased and was significantly greater than change in the control group (p = 0.01). This community-based participatory research study was considered successful because weight gain was prevented.

ABSTRACT

INTRODUCTION: Engaging community residents to obtain their feedback in conducting clinical research, and including them as leaders in implementing applicable health advances is crucial for success and sustaining large center awards. METHODS: Forty-four adult men and women participated in one of four focus groups. Two groups each (one African American and one Caucasian) were conducted in Baton Rouge and in New Orleans. RESULTS: In an effort to determine the knowledge, attitudes, and beliefs Louisiana residents have about the Louisiana Clinical and Translational Science (LA CaTS) Center concept, four main themes emerged from focus group participants concerning the state's research institutions, and what it means to have these institutions operating under one umbrella to improve the quality of health of its people: (1) academic/research institutions of the State are uniformly widely recognized and held in high regard; (2) increasing awareness of clinical research is a necessity; (3) establishing the LA CaTS Center is an excellent idea; and (4) effective communication including delivery style is crucial to partnerships and especially to the community. CONCLUSION: Focus group discussions can provide insight into community residents' perceptions, beliefs, motivations, and patterns of behavior for strategically planning for large center awards.

ABSTRACT

BACKGROUND: The medical home is an organizational approach for improving care, improving patient experience, and reducing costs. The purpose of this qualitative project was to obtain input from patients that could be used to improve their experiences in the medical home for ongoing disease management and health improvement and to obtain their recommendations for the most effective methods to involve patients in shaping system policies, procedures, and practices consistent with patient- and family-centered care principles. METHODS: We conducted cognitive interviews to complete patient experience surveys, structured focus groups, and exit surveys. A sample of 32 adults participated in cognitive interviews (n=15) and structured focus groups (n=17) using the nominal group technique (NGT). Exit surveys collected demographic information and input from patients about opportunities for their involvement in shaping medical homes. RESULTS: Cognitive interviews, NGT sessions, and exit surveys revealed patient-perceived strengths and inadequacies within the medical home. Better access to care, including more efficient appointment scheduling and reduced wait times to see a physician once patients arrived for scheduled appointments, was identified as a necessary improvement. Patients' positive perceptions included how the medical home helps them reach their health goals and their overall satisfaction with the quality of care received. CONCLUSION: The input received from patients through the methods used in this project was useful in revealing needed improvements within a medical home and, if resolved, will ensure that all patients have access to the kind of care that works for them.

ABSTRACT

Effective weight management interventions could reduce race-sex disparities in cardiovascular disease (CVD), yet little is known about factors associated with successful weight loss maintenance in race-sex subgroups. In the Weight Loss Maintenance trial (WLM), overweight/obese (BMI 25-45 kg/m(2)) adults who lost ≥4 kg in a 6-month behavioral weight loss intervention (phase I) were randomized into one of three 30-month maintenance interventions (phase II). To investigate predictors in subgroups, randomized groups were combined for this analysis. Of 1,685 phase I participants, 1,032 (61%) entered phase II, including 12% black men (BM), 26% black women (BW), 25% white men (WM), and 37% white women (WW). Weight change over the 36-month study ranged from -2.3% (95% confidence interval = -3.1 to -1.5%) in BW to -4.5% (95% confidence interval = -5.7 to -4.0%) in WM, the result of differential weight loss during phase I. Within race, men lost significantly more weight than women, but within sex group, weight loss did not differ significantly between races. Although participants regained weight during phase II, regain did not differ by race-sex group, and mean weight at the end of the study was significantly lower than phase I entry weight for each subgroup. In regression models, phase I weight loss predicted overall 36-month weight loss in all race-sex groups. Healthy dietary pattern at entry, improvement in dietary pattern, or both were predictive in three of four race-sex groups. Few other variables other than initial weight loss and dietary pattern were predictive. Future research should identify additional modifiable influences on long-term maintenance after a modest weight loss.

ABSTRACT

BACKGROUND: The purpose of this study was to determine if a short-term pedometer-based intervention results in immediate increases in time spent in moderate-to-vigorous physical activity (MVPA) compared to a minimal educational intervention. METHODS: A sample of 43 overweight adults 35 to 64 years of age participated in a one week pedometer-based feasibility trial monitored by accelerometry. Participants were randomized into a one-week education-only group or a group that also wore a pedometer. Accelerometer-measured MVPA was measured over 7 days at baseline and again for 7 days immediately post-intervention. RESULTS: Minutes of MVPA increased significantly in the overall sample (p = 0.02); however, the effect of adding the pedometer to the education program was not significant (p = 0.89). Mean (±SE) MVPA increased from 12.7 ± 2.4 min/day to 16.2 ± 3.6 min/day in the education-only group and from 13.2 ± 3.3 min/day to 16.3 ± 3.9 min/day in the education+pedometer group. The correlation between change in steps/day and change in MVPA was 0.69 (p<0.0001). CONCLUSIONS: The results of this study suggest that the addition of a pedometer to a short-term education program does not produce added benefits with respect to increasing physical activity in the Lower Mississippi Delta.

ABSTRACT

Collaboratively, the nutritional health problems of the Lower Mississippi Delta (LMD) region were examined and opportunities identified for conducting research interventions. To combat the nutritional health problems in the LMD, community residents yielded to a more comprehensive and participatory approach known as community-based participatory research (CBPR). Community residents partnered with academic researchers and other organizational entities to improve the overall quality of diet and health in their respective communities using CBPR. The collaborative work in the LMD focused on interventions conducted in each of three specific communities across three states: Marvell, Arkansas (Marvell NIRI), and its surrounding public school district; Franklin Parish in Louisiana (Franklin NIRI); and the city of Hollandale, Mississippi (Hollandale NIRI). This paper examined some of the research interventions conducted in Franklin, Hollandale, and Marvell NIRI respectively, how leadership emerged from each of these communities, and lessons learned as a result of the CBPR model.

ABSTRACT

In this paper, challenges to recruiting African Americans specifically for a dietary feeding trial are examined, learning experiences gained and suggestions to overcome these challenges in future trials are discussed. A total of 333 individuals were randomized in the trial and 234 (167 sibling pairs and 67 parents/siblings) completed the dietary intervention and required DNA blood sampling for genetic analysis. The trial used multiple strategies for recruitment. Hand distributed letters and flyers through mass distribution at various churches resulted in the largest number (n = 153, 46%) of African Americans in the trial. Word of mouth accounted for the second largest number (n = 120, 36%) and included prior study participants. These two recruitment sources represented 82% (n = 273) of the total number of individuals randomized in GET READI. The remaining 18% (n = 60) consisted of a combination of sources including printed message on check stubs, newspaper articles, radio and TV appearances, screening events and presentations. Though challenging, the recruitment efforts for GET READI produced a significant number of African American participants despite the inability to complete the trial as planned because of low recruitment yields. Nevertheless, the recruitment process produced substantial numbers that successfully completed all study requirements.

ABSTRACT

To determine how many steps·day(-1) equate to current moderate-to-vigorous physical activity (MVPA) guidelines in a population from the Lower Mississippi Delta (LMD) of the United States, 58 overweight adults wore an Actigraph accelerometer (GT3X) for up to 2 weeks. Min·day(-1) in MVPA was a good predictor of steps·day(-1) (r(2) = 0.62; p < 0.001; linear regression), such that 30 min of daily MVPA equated to 9154 steps·day(-1) (mixed-model approach). Using receiver operating characteristic analysis, sensitivity and specificity were optimized at 8357 steps·day(-1). Results indicate that overweight residents of the LMD should be accumulating at least 8300-9100 steps·day(-1) to meet the recommendation of 30 min·day(-1) MVPA.

ABSTRACT

Little is known about the transition in behaviors from short-term weight loss to maintenance of weight loss. We wanted to determine how short-term and long-term weight loss and patterns of weight change were associated with intervention behavioral targets. This analysis includes overweight/obese participants in active treatment (n = 507) from the previously published PREMIER trial, an 18-month, multicomponent lifestyle intervention for blood pressure reduction, including 33 intervention sessions and recommendations to self-monitor food intake and physical activity daily. Associations between behaviors (attendance, recorded days/week of physical activity, food records/week) and weight loss of ≥5% at 6 and 18 months were examined using logistic regression. We characterized the sample using 5 weight change categories (weight gained, weight stable, weight loss then relapse, late weight loss, and weight loss then maintenance) and analyzed adherence to the behaviors for each category, comparing means with ANOVA. Participants lost an average of 5.3 ± 5.6 kg at 6 months and 4.0 ± 6.7 kg (4.96% of body weight) by 18 months. Higher levels of attendance, food record completion, and recorded days/week of physical activity were associated with increasing odds of achieving 5% weight loss. All weight change groups had declines in the behaviors over time; however, compared to the other four groups, the weight loss/maintenance group (n = 154) had statistically less significant decline in number of food records/week (48%), recorded days/week of physical activity (41.7%), and intervention sessions attended (12.8%) through 18 months. Behaviors associated with short-term weight loss continue to be associated with long-term weight loss, albeit at lower frequencies. Minimizing the decline in these behaviors may be important in achieving long-term weight loss.

ABSTRACT

BACKGROUND: The Weight Loss Maintenance Trial (WLM) compared two long-term weight-maintenance interventions, a personal contact arm and an Internet arm, with a no-treatment control after an initial six-month Phase I weight loss program. The Internet arm focused on use of an interactive website for support of long-term weight maintenance. There is limited information about patterns of website use and specific components of an interactive website that might help promote maintenance of weight loss. OBJECTIVE: This paper presents a secondary analysis of the subset of participants in the Internet arm and focuses on website use patterns and features associated with long-term weight maintenance. METHODS: Adults at risk for cardiovascular disease (CVD) who lost at least 4 kilograms in an initial 20-week group-based, behavioral weight-loss program were trained to use an interactive website for weight loss maintenance. Of the 348 participants, 37% were male and 38% were African American. Mean weight loss was 8.6 kilograms. Participants were encouraged to log in at least weekly and enter a current weight for the 30-month study period. The website contained features that encouraged setting short-term goals, creating action plans, and reinforcing self-management habits. The website also included motivational modules, daily tips, and tailored messages. Based on log-in and weight-entry frequency, we divided participants into three website use categories: consistent, some, and minimal. RESULTS: Participants in the consistent user group (n = 212) were more likely to be older (P = .002), other than African American (P = .02), and more educated (P = .01). While there was no significant difference between website use categories in the amount of Phase I change in body weight (P = .45) or income (P = .78), minimal website users (n = 75) were significantly more likely to have attended fewer Phase I sessions (P = .001) and had a higher initial body mass index (BMI) (P < .001). After adjusting for baseline characteristics including initial BMI, variables most associated with less weight regain included: number of log-ins (P = .001), minutes on the website (P < .001), number of weight entries (P = .002), number of exercise entries (P < .001), and sessions with additional use of website features after weight entry (P = .002). CONCLUSION: Participants defined as consistent website users of an interactive behavioral website designed to promote maintenance of weight loss were more successful at maintaining long-term weight loss.

ABSTRACT

Recruitment strategies employed by four clinical centers across the US and a coordinating center were examined to identify successful overall and minority-focused recruitment strategies for the PREMIER multicenter trial of lifestyle changes for blood pressure control. The goal was to recruit 800 adults (40% African Americans) with systolic blood pressure of 120-159 mm Hg and diastolic of 80-95 mm Hg, not taking antihypertensive medication. Clinical centers used combinations of mass distribution of brochures, mass media, email distribution lists, screening events, and a national website. Culturally appropriate strategies for African Americans were designed by a Minority Implementation (MI) committee. Diversity training was provided for study staff, and African Americans were included in the study design process. Main recruitment outcomes were number overall and number of African Americans recruited by each strategy. Of the 810 randomized PREMIER participants, 279 (34%) were African American with site-specific percentages of 56%, 46%, 27%, and 8%. Of African Americans recruited, 151 (54%) were from mass distribution of brochures (mailed letter, flyer included in Val-Pak coupons, or other), 66 (24%) from mass media (printed article, radio, TV story or ads, 52 (19%) from word of mouth, and 10 (3%) from email/website and screening events combined. Yields for Non-Hispanic Whites were 364 (69%) from brochures, 71 (13%) from mass media, 49 (9%) from word of mouth and 47 (9%) from email/website and screening events. Mass distribution of brochures was relatively more effective with Non-Hispanic Whites, while African Americans responded relatively better to other recruitment strategies.
