Differences in Weight Loss by Race and Ethnicity in the PRIDE Trial: a Qualitative Analysis of Participant Perspectives

A culturally and linguistically adapted text-message Diabetes Prevention Program for Latinos: Feasibility, acceptability, and preliminary effectiveness

Despite the general positive outcomes of the Diabetes Prevention Program (DPP), the program's reach, adherence, and effectiveness among Latinos are still suboptimal. Text-message DPP can potentially overcome barriers and improve DPP outcomes for this group. We aimed to assess the feasibility, acceptability, and preliminarily effectiveness of a culturally and linguistically adapted text-message DPP for Latinos. We enrolled 26 eligible Spanish-speaking Latino adults at risk of developing type 2 diabetes (A1c = 5.7%-6.4%, body mass index ≥25) in a 6-month culturally and linguistically adapted text-message DPP. Participants received (i) two to three daily automated text-messages about healthy eating, physical activity, problem-solving skills, lifestyle change motivation, and logistics, (ii) on-demand keyword-driven messages, and (iii) on-demand chat messages with a DPP coach. Outcomes included feasibility (e.g. adherence), acceptability (e.g. satisfaction), and preliminary effectiveness (e.g. weight loss). Twenty-four participants completed the program and follow-up assessments. Participants' mean body weight changed from 191.2 to 186.7 pounds (P = .004); 45.8% of participants lost ≥3%, and 29.2% lost ≥5% of body weight. Body mass index and waist circumference were also reduced [0.9 kg/m2 (P = .003) and 1.1 cm (P = .03), pre-post]. Self-reported physical activity frequency was increased (P = .003). No statistically significant changes in diet quality were found. Most participants were satisfied with the program and perceived it to help prevent diabetes. Our pilot study of an innovative text-message DPP for Latinos demonstrated the program was acceptable, feasible, and potentially effective. Using text-message for DPP can reduce barriers to in-person participation by increasing the program's reach without compromising fidelity and effectiveness.

Adults' perceived health promotion needs in the prediabetes stage: a meta-synthesis study

Introduction

One of the methods to promote pre-diabetic patients' adherence to preventive behaviors and improving their lifestyle is to pay attention to their needs in the designed educational programs. Therefore, this study was conducted with the aim of identifying the needs of individuals with prediabetes.

Methodology

Three databases, including ISI/Web of Sciences, PubMed, Scopus were searched without time limitation until August 2022. The quality of the included studies was assessed using the Critical Appraisal Skills Programme tool. This study was reported according to the Enhancing Transparency in Reporting the Synthesis of Qualitative Research guidelines and to achieve the research goal, Sandelowski and Barroso's seven-step meta-synthesis method (2007) was used. Thematic synthesis was used to analyses the data.

Results

Out of the 1934 studies obtained, 34 studies were finally examined and 805 codes were recorded based on the extracted data. Through synthesizing and analyzing the primary studies, 8 main themes were extracted regarding individuals' needs in the prediabetes stage: Information needs, Cultural needs, psychological needs, Social support needs, Education needs, Financial needs, Service needs and Skill needs.

Discussion and Conclusions

The perceived needs and their types in each of the dimensions in detail can be a proper guide for designing educational programs and various interventions to control the prediabetes condition, leading to a reduction in the prevalence of type 2 diabetes in the society.

Examining paradoxical session attendance and weight loss relationships in a clinic based lifestyle modification intervention

Objective

Evaluations of lifestyle modification interventions (LMIs), modeled after the Diabetes Prevention Program, have repeatedly shown a dose-response relationship between session attendance and weight loss. Despite this, not all participants had "average" weight loss experiences. Nearly one-third of LMI participants experienced unexpected, paradoxical outcomes (i.e., high attendance with little weight loss, and low attendance with clinically significant weight loss). Paradoxical weight-loss outcomes were characterized based on session attendance among participants in a group-based LMI in a real-world healthcare setting. This group-based LMI was delivered over 1 year to participants with the possibility of attending up to 25 sessions total.

Methods

LMI participants identified in 2010-2017 from electronic health records were characterized as having low (<75%) or high (≥75%) session attendance. Weight-loss outcomes were defined as expected (≥5%, high-attendance; <5%, low-attendance) or paradoxical (≥5%, low-attendance; <5%, high-attendance). Paradoxical-outcome-associated characteristics were identified using logistic regression.

Results

Among 1813 LMI participants, 1498 (82.6%) had low and 315 (17.4%) high session attendance; 555 (30.6%) had paradoxical outcomes, comprising 415 (74.8%) responders (≥5% weight-loss) and 140 (25.2%) non-responders (<5% weight-loss). Among participants with high session attendance, paradoxical non-responders were more likely to be female (odds ratio [OR]: 2.76; 95% confidence interval [CI]: 1.32, 5.77) and have type 2 diabetes (OR: 3.32; 95% CI: 1.01, 10.95). Among low-attendance participants, paradoxical responders were more likely to be non-Hispanic White and less likely to be non-Hispanic Black (OR: 0.35; 95% CI: 0.18, 0.69), non-Hispanic Asian (OR: 0.40; 95% CI: 0.22, 0.73), or Hispanic (OR: 0.53; 95% CI: 0.35, 0.80).

Conclusions

In a healthcare setting, nearly one-third of LMI participants experienced paradoxical outcomes. More research is needed to understand the facilitators and barriers to weight loss above and beyond session attendance.

Factors that predict weight loss success differ by diet intervention type

Background

Many types of diet intervention can achieve negative energy balance and successful weight loss in persons with obesity. However, within any dietary strategy, there is large inter-individual variation in the weight loss response. The aim of this study is to determine factors that predict weight loss success for diet interventions that vary by macronutrient and caloric composition.

Methods

Participants with BMI 30.0 to 49.9 kg/m2 self-selected one of three diet intervention trials for weight loss: low carbohydrate (LOW CHO), low fat (LOW FAT), or low calorie (LOW KCAL). Multivariable regression models were developed to determine the significance of predictor demographic, body composition, metabolic, clinical, and dietary variables for each diet type.

Results

Weight loss over 12-16 weeks averaging -5.1 ± 4.0 kg from baseline weight, p < 0.001, was not significantly different among diet types. Several different factors were identified that account for the inter-individual variance in weight loss success. Regardless of diet type, the most robust predictor of weight loss success was completion of the intervention, accounting for 20-30% of the variance. Factors predicting diet intervention completion were age, physical activity level, blood leptin level, blood pressure, and the amount of weight loss occurring. Differences by diet type in cardiometabolic risk factor reduction were identified with LOW CHO decreasing glycemia/insulinemia factors, LOW FAT decreasing lipidemia factors, and LOW KCAL decreasing inflammatory factors.

Conclusion

These data provide evidence to inform more precise and personalized approaches to diet intervention for weight loss and cardiometabolic health.

Curated collections for educators: Nine key articles and article series for teaching qualitative research methods

Background

Qualitative research explains observations, focusing on how and why phenomena and experiences occur. Qualitative methods go beyond quantitative data and provide critical information inaccessible through quantitative methods. However, at all levels of medical education, there is insufficient exposure to qualitative research. As a result, residents and fellows complete training ill-equipped to appraise and conduct qualitative studies. As a first step to increasing education in qualitative methods, we sought to create a curated collection of papers for faculty to use in teaching qualitative research at the graduate medical education (GME) level.

Methods

We conducted literature searches on the topic of teaching qualitative research to residents and fellows and queried virtual medical education and qualitative research communities for relevant articles. We searched the reference lists of all articles found through the literature searches and online queries for additional articles. We then conducted a three-round modified Delphi process to select papers most relevant to faculty teaching qualitative research.

Results

We found no articles describing qualitative research curricula at the GME level. We identified 74 articles on the topic of qualitative research methods. The modified Delphi process identified the top nine articles or article series most relevant for faculty teaching qualitative research. Several articles explain qualitative methods in the context of medical education, clinical care, or emergency care research. Two articles describe standards of high-quality qualitative studies, and one article discusses how to conduct the individual qualitative interview to collect data for a qualitative study.

Conclusions

While we identified no articles reporting already existing qualitative research curricula for residents and fellows, we were able to create a collection of papers on qualitative research relevant to faculty seeking to teach qualitative methods. These papers describe key qualitative research concepts important in instructing trainees as they appraise and begin to develop their own qualitative studies.
