Effect of the National Diabetes Prevention Program on Weight Loss for English- and Spanish-Speaking Latinos

Purpose: To study the effect of the National Diabetes Prevention Program (NDPP) on weight loss in Latinos. Design: No-control, cohort study comparing Latino and non-Hispanic white (NHW) participants. Setting: A health-care system. Participants: Five hundred sixty-seven Latino and 175 NHW patients who enrolled in the NDPP. A total of 45.2% of Latinos selected the Spanish-language NDPP. Intervention: The NDPP is a nationwide translation of a clinical trial and seeks to prevent diabetes through weight loss in a yearlong group program. Measures: Independent variables included ethnicity, class language, and number of sessions attended. Main outcomes were initial attendance, number of sessions attended, and weight loss. Analysis: Multivariate logistic regression and analysis of covariance were used to determine differences in NDPP outcomes by ethnicity, language, and number of sessions attended. Results: Mean attendance was 8.60 of 22 sessions. Each session was associated with 0.30% (±0.02; P < .001) body weight loss. Latinos were half as likely to attend as NHWs, odds ratio 0.52 ( P < .001). Latino attendees came to 2.67 ± 0.63 ( P < .001) fewer sessions than NHWs. There were no weight loss differences by ethnicity after controlling for attendance. Outcomes did not differ among Latinos in the English- and Spanish-language NDPP. Conclusion: Latinos appeared to benefit less from the NDPP compared to NHWs, likely due to lower attendance rates. Further efforts are needed to support their participation.

Purpose: The National Diabetes Prevention Program (NDPP) is a widely disseminated lifestyle intervention. Attendance is problematic, leading to suboptimal weight loss, especially among racial/ethnic minority participants. We conducted a novel “presession” protocol to improve engagement of diverse NDPP candidates, comparing NDPP participants who attended a presession to those who did not on attendance and weight loss outcomes. Design: Longitudinal cohort study. Setting: A safety net health-care system. Participants: A total of 1140 patients with diabetes risks (58.9% Hispanic, 19.8% non-Hispanic black, 61.8% low income). Intervention: The NDPP has been delivered in a Denver, Colorado health-care system since 2013. The program included 22 to 25 sessions over 1 year. Beginning September 2016, individuals were required to attend a presession before enrollment that focused on (1) increasing risk awareness, (2) motivational interviewing to participate in the NDPP, and (3) problem-solving around engagement barriers. Measures: Duration and intensity of NDPP attendance and weight loss. Analysis: Outcomes of 75 presession participants who enrolled in the NDPP were compared to 1065 prior participants using analysis of covariance and multivariable logistic regression. Results: Presession participants stayed in the NDPP 99.8 days longer ( P < .001) and attended 14.3% more sessions ( P < .001) on average than those without a presession. Presession participants lost 2.0% more weight ( P < .001) and were 3.5 times more likely to achieve the 5% weight loss target ( P < .001). Conclusion: Presessions may improve NDPP outcomes for individuals from diverse backgrounds. A full-scale trial is needed to determine whether presessions reliably improve NDPP effectiveness.

Purpose The purpose of this report is (1) to describe the use of the American Association of Diabetes Educators’ (AADE’s) model of implementation of the National Diabetes Prevention Program through nationally certified diabetes self-management education (DSME) programs and (2) to report the aggregated program outcomes as defined by the Diabetes Prevention and Recognition Program standards of the Centers for Disease Control and Prevention (CDC). Methods In 2012, the AADE worked with the CDC to select 30 certified DSME programs for National Diabetes Prevention Program delivery. For the following 3 years, the AADE continued to work with 25 of the 30 original programs. Results for all CDC recognition standards have been collected from these 25 programs and analyzed as aggregated data over the course of 36 months. Results At the end of the full-year program, average percentage body weight loss for participants across all 25 programs exceeded the CDC’s minimum requirement of 5% weight loss. All programs on average met the CDC requirements for program attendance. Conclusion Increasing access to the National Diabetes Prevention Program, through an array of networks, including certified DSME programs, will better ensure that people are able to engage in an effective approach to reducing their risk of diabetes.
