OBJECTIVEType 2 diabetes is growing in epidemic proportions and disproportionately affects lower-income, diverse communities. Text messaging may provide one of the most rapid methods to overcome the “digital divide” to improve care.RESEARCH DESIGN AND METHODSA randomized, nonblinded, parallel-groups clinical trial design allocated N = 126 low-income, Hispanic participants with poorly controlled type 2 diabetes to receive the Dulce Digital intervention or usual care (UC). Dulce Digital participants received up to three motivational, educational, and/or call-to-action text messages per day over 6 months. The primary outcome was HbA1c; lipids, blood pressure, and BMI were secondary outcomes. Satisfaction and acceptability were evaluated via focus groups and self-report survey items.RESULTSThe majority of patients were middle-aged (mean age 48.43 years, SD 9.80), female (75%), born in Mexico (91%), and uninsured (75%) and reported less than a ninth-grade education level (73%) and mean baseline HbA1c 9.5% (80 mmol/mol), SD 1.3, and fasting plasma glucose 187.17 mg/dL, SD 64.75. A statistically significant time-by-group interaction effect indicated that the Dulce Digital group achieved a significantly greater reduction in HbA1c over time compared with UC (P = 0.03). No statistically significant effects were observed for secondary clinical indicators. The number of blood glucose values texted in by participants was a statistically significant predictor of month 6 HbA1c (P < 0.05). Satisfaction and acceptability ratings for the Dulce Digital intervention were high.CONCLUSIONSUse of a simple, low-cost text messaging program was found to be highly acceptable in this sample of high-risk, Hispanic individuals with type 2 diabetes and resulted in greater improvement in glycemic control compared with UC.

Background: Many CpGs become hyper or hypo-methylated with age. Multiple methods have been developed by Horvath et al. to estimate DNA methylation (DNAm) age including Pan-tissue, Skin & Blood, PhenoAge, and GrimAge. Pan-tissue and Skin & Blood try to estimate chronological age in the normal population whereas PhenoAge and GrimAge use surrogate markers associated with mortality to estimate biological age and its departure from chronological age. Here, we applied Horvath's four methods to calculate and compare DNAm age in 499 subjects with type 1 diabetes (T1D) from the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) study using DNAm data measured by Illumina EPIC array in the whole blood. Association of the four DNAm ages with development of diabetic complications including cardiovascular diseases (CVD), nephropathy, retinopathy, and neuropathy, and their risk factors were investigated. Results: Pan-tissue and GrimAge were higher whereas Skin & Blood and PhenoAge were lower than chronological age (p < 0.0001). DNAm age was not associated with the risk of CVD or retinopathy over 18-20 years after DNAm measurement. However, higher PhenoAge (β = 0.023, p = 0.007) and GrimAge (β = 0.029, p = 0.002) were associated with higher albumin excretion rate (AER), an indicator of diabetic renal disease, measured over time. GrimAge was also associated with development of both diabetic peripheral neuropathy (OR = 1.07, p = 9.24E−3) and cardiovascular autonomic neuropathy (OR = 1.06, p = 0.011). Both HbA1c (β = 0.38, p = 0.026) and T1D duration (β = 0.01, p = 0.043) were associated with higher PhenoAge. Employment (β = − 1.99, p = 0.045) and leisure time (β = − 0.81, p = 0.022) physical activity were associated with lower Pan-tissue and Skin & Blood, respectively. BMI (β = 0.09, p = 0.048) and current smoking (β = 7.13, p = 9.03E−50) were positively associated with Skin & Blood and GrimAge, respectively. Blood pressure, lipid levels, pulse rate, and alcohol consumption were not associated with DNAm age regardless of the method used. Conclusions: Various methods of measuring DNAm age are sub-optimal in detecting people at higher risk of developing diabetic complications although some work better than the others.

Purpose The purpose of the study was to test the preliminary effectiveness, feasibility, and acceptability of a peer-led, culturally appropriate, Diabetes Prevention Program (DPP)–based lifestyle intervention for Latina women at high-risk for type 2 diabetes (T2DM). Methods Participants (N = 61) were overweight/obese (body mass index [BMI] ≥25) Latina women with no diabetes, at elevated risk either due to midlife age (45–65 years; n = 37) or history of gestational diabetes mellitus (n = 24). The study used a 1-group pretest-posttest design and offered 12 weeks of peer-led education sessions in a community setting. The intervention targeted physical activity and dietary behaviors to facilitate weight reduction and included culturally appropriate content, age-specific health information, and stress/emotion management strategies. Clinical and self-report assessments were conducted at baseline, month 3, and month 6. Results Mean participant age was 47.8 years (SD = 10.8). Most (91.2%) were born in Mexico, and 43.3% had a ninth-grade education or less. At month 6, participants achieved a mean reduction of 4.1% body weight (7 lb [3.2 kg]). Statistically significant improvements were observed for dietary behaviors, stress, and depression symptoms. Attrition was low, 5% (3 women). Focus groups indicated that intervention content increased knowledge, was applicable, highly valued, culturally relevant, and would be recommended to others. Conclusions This culturally tailored DPP adaptation was feasible and acceptable for 2 groups of Latina women at high-risk for T2DM and showed preliminary effectiveness in reducing weight and modifying self-reported dietary behaviors, stress, and depression symptoms. Further research is needed to identify ways to enhance weight loss and diabetes prevention in this at-risk, underserved population.
