摘要

Background

Minoritized populations face many barriers to accessing evidence-based diabetes intervention.

Objectives

To evaluate the feasibility, acceptability, and potential efficacy of a social media-based intervention to improve glycemic control among Chinese Americans with type 2 diabetes.

Design

A pilot randomized controlled trial (RCT) with 3-month and 6-month follow-ups.

Participants

Chinese Americans (n = 60, mean age 54.3 years old) with limited education (70.0% with high school or less) and low income (50.0% with annual household income < $25,000), and 88.3% have limited English proficiency.

Intervention

Culturally and linguistically tailored diabetes videos (two videos/week for 12 weeks) delivered via social media and support calls from community health workers.

Main Measures

Primary outcomes include feasibility (video watch rate, biweekly call completion rate, and retention rates), acceptability (patient satisfaction), and HbA1c. Secondary health-related outcomes include body weight, BMI, physical activity, and dietary intake. Video watch rate and biweekly call completion rate were assessed at baseline and 3 months, while others were measured at baseline, 3 months, and 6 months.

Results

We observed high feasibility and acceptability of the intervention, with retention rates over 87%, an 89% video watch rate, 80% biweekly phone call completion, and a satisfaction rating of 9 out of 10. The intervention group showed a significantly greater increase in fruit intake compared to the control group (0.15 cups vs. − 0.44 cups, adj_p = 0.023) at 3 months. While no significant differences in other outcomes were observed between the groups, the intervention group showed significant improvements in key outcomes, including reduced HbA1c levels (− 1.08%, adj_p < 0.001), weight loss (− 5.15 lbs, adj_p = 0.004), lower BMI (− 0.83, adj_p = 0.023), and reduced starchy food intake (− 0.33 cups, adj_p = 0.033) at 6 months.

Conclusions

The observed high feasibility and acceptability suggest the intervention’s feasibility. However, due to the limited sample size, a larger-scale RCT is warranted to test the efficacy of the intervention.
