To study the effect of the National Diabetes Prevention Program (NDPP) on weight loss in Latinos.
No-control, cohort study comparing Latino and non-Hispanic white (NHW) participants.
A health-care system.
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.
The NDPP is a nationwide translation of a clinical trial and seeks to prevent diabetes through weight loss in a yearlong group program.
Independent variables included ethnicity, class language, and number of sessions attended. Main outcomes were initial attendance, number of sessions attended, and weight loss.
Multivariate logistic regression and analysis of covariance were used to determine differences in NDPP outcomes by ethnicity, language, and number of sessions attended.
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.
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.
研究国家糖尿病预防计划（NDPP）对拉丁裔人群体重减轻的影响。
无对照队列研究，比较拉丁裔和非西班牙裔白人（NHW）参与者。
一个医疗保健系统。
567名拉丁裔和175名参加NDPP的NHW患者。共有45.2%的拉丁裔选择了西班牙语版的NDPP。
NDPP是一项全国性的临床试验转化项目，旨在通过为期一年的小组项目中的体重减轻来预防糖尿病。
自变量包括种族、课程语言和参加的课程节数。主要结果是初始出勤率、参加的课程节数和体重减轻情况。
采用多因素逻辑回归和协方差分析来确定按种族、语言和参加课程节数划分的NDPP结果差异。
平均出勤率为22节课程中的8.60节。每节课程与0.30%（±0.02；P <.001）的体重减轻相关。拉丁裔参加的可能性是非西班牙裔白人的一半，优势比为0.52（P <.001）。拉丁裔参与者比非西班牙裔白人少参加2.67±0.63节课程（P <.001）。在控制出勤率后，按种族划分的体重减轻情况没有差异。英语版和西班牙语版NDPP中的拉丁裔参与者结果没有差异。
与非西班牙裔白人相比，拉丁裔从NDPP中获得的益处似乎较少，可能是由于出勤率较低。需要进一步努力支持他们的参与。
