Clinical Trial Summary

The goal of this study is to examine the efficacy of the video-based Diabetes Prevention Program (DPP) + Community-supported agriculture (CSA) (hereafter INCLUDE) intervention compared with a wait-list control group (hereafter CONTROL) on diabetes prevention among Chinese immigrants with T2D in NYC. Participants will be randomized with equal allocation to one of the two groups. The INCLUDE group will receive one culturally tailored DPP brief video/week for 24 weeks delivered via WeChat. They will also have access to the CSA program that Co-I Dr. Stella Yi has built in existing and ongoing community-partnered work in Brooklyn Chinatown. The CONTROL group will continue to receive their usual care and, at the end of the study, they will receive DPP videos. Measurements will occur at baseline, 3, and 6 months. This study will provide critical information on whether it is efficacious to use an existing social media platform plus CSA support to enhance access to DPP. If the intervention is proven efficacious, this project can provide important data for future scaling of this intervention. This study may serve as a transformative new model to enhance access to culturally tailored diabetes education and promote health equity for underserved limited English proficiency (LEP) immigrant and minority groups.

Description:

Chinese immigrants are the second largest immigrant group in the U.S., who suffer disproportionately high type 2 diabetes (T2D) burden and have poor diabetes outcomes. The Diabetes Prevention Program (DPP) is an evidence-based intervention to prevent or delay T2D. However, many social determinants of health (SDOH) barriers limit the access of DPP to underserved Chinese immigrants, including high rates of LEP, poverty, lack of health insurance, and poor access to care. Furthermore, there is a significant shortage of cultural- and linguistic-concordant providers to deliver DPP. Given the high T2D burden and rapid growth in the Chinese immigrant population, there is an urgent need for research to make DPP accessible to this minority group. High social media use (e.g., WeChat) in Chinese immigrants suggests a promising mechanism for enhancing access to DPP. Yet, this mobile health (mHealth) intervention alone is likely insufficient to address many SDOH barriers reported by LEP Chinese immigrants, including food insecurity, and lack of access to fruits and vegetables. Community-supported agriculture (CSA) has been demonstrated to be an effective way to improve food security in White populations, and may help to address food access issues in LEP Chinese immigrants. Guided by the NIMHD Research Framework, the investigators argue that a mHealth DPP intervention (individual level) that is supplemented with a culturally appropriate CSA (community level) with complementary nutrition/produce preparation education is a novel model for enhancing access to DPP and addressing SDOH barriers in LEP Chinese immigrants. The investigators' pilot work demonstrates the feasibility, acceptability, and potential efficacy of WeChat-delivered educational videos targeting T2D management, and Co-I Dr. Stella Yi's pilot study has found high feasibility of the CSA model in LEP Chinese immigrants. Building upon these pilot data, the investigators will adapt their current T2D management intervention to include video content relevant to DPP and combine it with a CSA model. The goal of this study is to examine the efficacy of the video-based DPP+CSA (hereafter INCLUDE) intervention compared with a wait-list control group (hereafter CONTROL) on diabetes prevention among Chinese immigrants with T2D in NYC. Participants will be randomized with equal allocation to one of the two groups. The INCLUDE group will receive one culturally tailored DPP brief video/week for 24 weeks delivered via WeChat. They will also have access to the CSA program that Co-I Dr. Stella Yi has built in existing and ongoing community-partnered work in Brooklyn Chinatown. The CONTROL group will continue to receive their usual care and, at the end of the study, they will receive DPP videos. Measurements will occur at baseline, 3, and 6 months. This study will provide critical information on whether it is efficacious to use an existing social media platform plus CSA support to enhance access to DPP. If the intervention is proven efficacious, this project can provide important data for future scaling of this intervention. This study may serve as a transformative new model to enhance access to culturally tailored diabetes education and promote health equity for underserved LEP immigrant and minority groups.

• PreDiabetes
• Prediabetic State

Intervention

Behavioral:
• Diabetes Prevention Program (DPP)
Video-based intervention to prevent or delay Type 2 Diabetes. Includes both educational and social cognitive theory (SCT)-based behavioral content. Each video lasts about 5 minutes in duration.
• Community-Supported Agriculture (CSA)
Provides weekly and culturally appropriate fresh produce and in-language education on nutrition, healthy cooking demonstrations, and culturally tailored recipes for participants. Enables participants to socialize with other Chinese immigrants in the program as a way to enhance social cohesion and support.

Assessed via 10-point Likert scale ranging from 0 (not confident) to 9 (very confident). Scores range from 0-180; higher scores indicate higher confidence level in resisting desire to eat. An increase in scores indicates confidence levels in resisting desire to eat increased during the observation period.	Baseline, Month 3
