Participant engagement in a community health worker-delivered intervention and type 2 diabetes clinical outcomes: a quasiexperimental study in MexicanAmericans.

OBJECTIVES: This study helps to fill the existing research gap related to participant engagement in behavioural interventions and diabetes management. We examined type 2 diabetes control over time among Mexican Americans by level of engagement in a chronic care management (CCM) program that included community health worker (CHW)-delivered multilevel interventions. The programme complemented clinical care and promoted behaviour changes to improve diabetes self-management. DESIGN: Quasiexperimental study. SETTING: The study was implemented in the Rio Grande Valley region in the USA. Recruitment was conducted in clinics and community events. All other visits were provided in participant homes and community locations. PARTICIPANTS: 5649 adults (aged ≥18 years) with poorly controlled type 2 diabetes who enrolled in a community-delivered CCM programme between September 2013 and 2018. INTERVENTIONS: The intervention comprised two components: CHW home visits conducted every 3 months and diabetes self-management education (DSME) classes provided in community locations. PRIMARY OUTCOME MEASURES: The primary outcome was haemoglobin A1c (HbA1c) measured at baseline every 3 months for up to 24 months. We first examined changes in HbA1c levels over time. The number of completed CHW and DSME encounters was used to classify participants into engagement groups-high engagement defined as ≥10 encounters (n=2952); low engagement defined as 1-9 encounters (n=2697). We used univariable and multivariable longitudinal linear regression models with a generalised estimating equation method. We tested interactions between engagement groups and time. RESULTS: Participants' mean HbA1c decreased from 10.20% at baseline to 8.93% (p<0.0001) at 3 months, remaining stable thereafter. Changes in HbA1c were statistically different between the engagement groups. High engagement participants had lower HbA1c levels over the first 15 months of the follow-up period compared with low engagement participants, as compared at 3 months (-0.44%, 95% CI -0.57% to -0.31%; p<0.0001), 6 months (-0.31%, 95% CI -0.43% to -0.14%; p<0.0001), 9 months (-0.27%, 95% CI -0.42% to -0.13%; p=0.0001), 12 months (-0.23%, 95% CI -0.37% to -0.08%; p=0.0025) and 15 months (-0.32%, 95% CI -0.54% to -0.10%; p=0.0040). At months 18, 21 and 24, the HbA1c differences were not statistically significant (18 months: -0.34%, 95% CI -0.77% to 0.08%; p=0.1086; 21 months: -0.22%, 95% CI -1.00% to 0.56%; p=0.5721; 24 months: -0.42%, 95% CI -1.38% to 0.55%; p=0.3966). CONCLUSIONS: Higher engagement in the CCM programme delivered by CHWs and coordinated with clinical care was associated with beneficial improvements in type 2 diabetes control, but both engagement groups showed strong improvements.

Motivation for weight loss among completers of a free community-based weight loss program in a US-Mexico border region: A self-determination theory perspective.

This study explores the perceptions and motivation for weight loss among participants who completed a free community-based weight loss program in a predominantly Hispanic and low-income region along the US-Mexico border using a Self-Determination Theory (SDT) perspective. This manuscript is timely as qualitative research on the effect of motivation as a factor in behavioral interventions to reduce overweight or obesity is currently lacking. Individual semi-structured interviews were conducted with 20 participants (80%, n = 16 female) who completed a community weight-loss intervention to assess motivation for weight loss and participating, and the role of social support and self-efficacy in weight loss. Directed content analysis was used with SDT guiding the questions and subsequent theme analysis. The findings communicate perspectives of participants relevant to 8 prominent themes. The regulation types and constructs related to SDT included: non-regulation, external regulation, introjected regulation, identified regulation, integrated regulation, and intrinsic regulation as well as competence and relatedness. Participants mentioned external sources of motivation, such as wanting to improve their physical appearance, and motivation due to financial incentives. Fewer participants reported intrinsic motivators, which the literature suggests are more likely to create lasting change and improved health behaviors. Understanding the motivation for behavior change and completion of weight loss programs is essential to help participants reach their goals effectively and sustain weight loss. A greater emphasis during weight loss programs on the motives for individuals to lose weight may help improve outcomes in weight-loss interventions. Additionally, increasing strategies targeted at enhancing intrinsic motivation for weight loss may be beneficial.

Exploration of Fatalism and Religiosity by Gender and Varying Levels of Engagement Among Mexican-American Adults of a Type 2 Diabetes Management Program.

Objectives: Purpose of study is to explore the roles religiosity and fatalistic beliefs play in diabetes management among newly, currently, and long-term enrolled Mexican-American participants in a Type 2 diabetes mellitus (T2DM) chronic care management program. Methods: In 2017, study participants (n = 15) completed a semi-structured interview in their preferred language (English or Spanish). Sample was stratified by amount of time individual had been enrolled as a participant of the Salud y Vida program: newly, currently, or long-term. Interviews assessed religious beliefs, beliefs concerning the cause(s) of diabetes, perceived relationship between religiosity and fatalistic beliefs with T2DM management, and the appropriateness of discussing such topics with a health professional. Interview responses were analyzed using ATLAS.ti 8. Results: Themes identified included: perceived autonomy over diabetes prognosis, motivators for self-care, discussions of personal beliefs in the healthcare setting, and the church's role in diabetes management. Conclusions: Among this sample, religiosity and religious fatalism played a complex role in coping with and managing diabetes. Long-term enrolled and male participants expressed beliefs of divine control over health, and a connection between religiosity and health behavior. Long-term enrolled participants felt religious and fatalistic beliefs may be suitable and beneficial to discuss in the healthcare setting.

Comparison of obstetrician-gynecologists and family physicians regarding weight-related attitudes, communication, and bias.

OBJECTIVES: To assess physician perceptions regarding weight-related communication, quality of care, and bias in obstetrics-gynecology (OBGYN) and family physician (FP) practices. METHODS: A cross-sectional survey study based on a convenient sampling of OBGYN and FP was conducted. Physicians completed a 40-question survey assessing perceived obesity management and weight bias in caring for female patients with body mass index ≥25kg/m2. RESULTS: Reponses from 51 physicians (25 OBGYN and 26 FP) were received. There was no difference between specialties in satisfaction with care or level of confidence in treating patients with obesity. However, OBGYNs reported more negative perceptions of patients with obesity (mean score 19.2±3.3 vs. 15.0±4.0, p<0.001) and greater weight bias (11.8±2.0 vs. 9.7±2.5, p<0.01) compared to FPs. OBGYNs were also more likely to expect less favorable treatment outcomes (13.3±2.5 vs. 15.5±2.8. p<0.01). Physicians between 31-50 years old displayed a significantly higher perception of weight bias in their profession when compared to the reference 21-30year olds, and for each unit increase in self-reported BMI there was a 0.18 average increase in the composite score for perceived weight bias. CONCLUSIONS: OBGYN physicians reported significantly higher levels of weight bias than FP physicians, indicating a need for improved education in OBGYN training. CLINICAL TRIAL REGISTRATION: N/A.

Evaluation of Event Physical Activity Engagement at an Open Streets Initiative Within a Texas-Mexico Border Town.

BACKGROUND: Open streets initiatives provide an opportunity to engage in physical activity (PA) freely by temporarily closing streets to motorized traffic. METHODS: Route counting estimation and event intercept surveys (n = 682) were conducted across 4 CycloBia events in Brownsville, TX, in 2015 to determine sociodemographics, PA engagement at the event, event awareness, and past CycloBia attendance. RESULTS: Cycling was the most commonly observed activity along the route (73.6%) followed by walking (22.9%). Attendees self-reported a median of 120 minutes in PA with 17.3% of attendees meeting recommended weekly PA guidelines at the event. Significant predictors of meeting PA guidelines via event PA engagement were past event attendance, sex, age, and Hispanic ethnicity. CONCLUSIONS: Findings suggest that CycloBia reached a large, low-income, predominantly Hispanic population and may be effective in promoting PA. Results help understand the effect of an open streets initiative on attendees living in a midsize, border city.

Benchmarking physician performance, part 2.

Part 1 of this article (January-February 2006) reviewed ways of measuring the work of physicians through methods such as data envelopment analysis (DEA) and relative value units (RVUs). These techniques provide insights into: 1. Who are the best-performing physicians? 2. Who are the underperforming physicians? 3. How can underperforming physicians improve? 4. What are the underperformers' performance targets? 5. How do you deal with full- and part-time physicians in a university setting? Part 2 compares the performance of 16 primary care physicians in the same medical specialty using DEA efficiency scores. DEA is capable of modeling multiple criteria and automatically determines the relative weights of each performance measure. This research also provides a preliminary framework for how work measurement and DEA can be used as a basis for a medical team or physician compensation system.

Benchmarking physician performance, Part 1.

The performance of 16 primary care physicians in the same medical specialty and university clinic is compared using data envelopment analysis (DEA) efficiency scores. DEA is capable of modeling multiple criteria and automatically determines the relative weights of each performance measure. In this research, the performance measures include physician work relative value units (RVUs) as an input variable and patient satisfaction and total billable charges as the two output variables. The results provide insights into: 1. Who are the best-performing physicians? 2. Who are the underperforming physicians? 3. How can underperforming physicians improve? 4. What are the underperformers' performance targets? 5. How do you deal with full- and part-time physicians in a university setting? This research also provides a preliminary framework for how work measurement and DEA analysis can be used as a basis for a medical team or physician compensation system.
