Association between ethnicity, language and metformin prescriptions in U.S. community health center patients with diabetes. Prev Med 2024; 185:108025. [PMID: 38834161 DOI: 10.1016/j.ypmed.2024.108025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2024] [Revised: 05/31/2024] [Accepted: 06/01/2024] [Indexed: 06/06/2024]
Abstract
BACKGROUND Metformin treatment is a recommended first-line medication for patients with type 2 diabetes. Latino patients are subject to factors that may modify their level of diabetes care, including medication prescription. We evaluated the odds of and times to metformin prescription among non-Latino whites, English-preferring Latinos, and Spanish-preferring Latinos with diabetes. METHODS We constructed a retrospective cohort of 154,368 adult patients from 835 community health centers (CHCs) across 20 states who were diagnosed with diabetes during the study. Patients were from non-Latino white, English-preferring Latino, and Spanish-preferring Latino ethnic/language groups. We modeled adjusted odds of metformin prescription and adjusted hazards (time-to-event) of metformin prescription after diabetes diagnosis and high hemoglobin A1c (HbA1c > 9) test results. RESULTS English-preferring Latinos had similar odds of metformin prescription (Odds Ratio (OR) = 1.01 (95% CI = 0.93, 1.09)), slightly lower time to metformin prescription after diabetes diagnosis (Hazard Ratio (HR) = 1.06(95% CI = 1.04, 1.09)), and similar time to metformin prescription after a high HbA1c result (HR = 1.04 (0.99, 1.09)) compared to non-Latino whites. Spanish-preferring Latinos had higher odds of metformin prescription (OR) = 1.42 (95% CI = 1.33, 1.52), and less time to prescription after diabetes diagnosis (HR = 1.18 (1.15, 1.20)) and after a high HbA1c result (HR = 1.15 (1.11, 1.20)). CONCLUSIONS Our analysis of metformin prescription patterns among non-Latino whites, English-preferring Latinos, and Spanish-preferring Latinos did not suggest a lower or slower tendency to prescribe metformin in Latino patients. Understanding disparities in diabetes diagnosis may require further investigation of medication adherence barriers, diet and exercise counseling, and multi-level influences on diabetes outcomes in Latino patients.

Budiastutik I, Kartasurya MI, Subagio HW, Widjanarko B. High Prevalence of Prediabetes and Associated Risk Factors in Urban Areas of Pontianak, Indonesia: A Cross-Sectional Study. J Obes 2022; 2022:4851044. [PMID: 36536959 PMCID: PMC9759381 DOI: 10.1155/2022/4851044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/17/2022] [Revised: 11/14/2022] [Accepted: 11/22/2022] [Indexed: 12/14/2022] Open
Abstract
Uncontrolled prediabetes can develop into Type 2 Diabetes mellitus (T2DM). The incidence of T2DM among adults in Pontianak, Indonesia was reported remarkably high. Therefore, this study aimed to investigate the risk factors for prediabetes in adults living in urban areas of Pontianak, Indonesia. A cross-sectional study was conducted in 5 subdistricts of Pontianak. A total of 506 adults underwent screening to obtain subjects with fasting blood glucose (FBS) of ≤124 mg/dL and aged >30 years. Blood pressure and body mass index (BMI) were measured. Interview using a structured questionnaire were performed to obtain data on predictor variables (age, sex, education, income, health insurance, tobacco use, history of hypertension, gout, high cholesterol level, frequency of exercise per week, and diabetic education). The prevalence of prediabetes among subjects was significantly high (76.4%). Subjects were predominantly above 40 years, female, had low income, low education level, and had health insurance. About a third of the subjects had a history of hypertension, gout, and high cholesterol level, respectively. The exercise frequency was mostly less than 3 times/week, and the BMI was mainly classified as overweight and obese. The result of spearman's rho correlation showed that age (r = 0.146; p=0.022) and BMI (r = 0.130; p=0.041) significantly correlated with prediabetes incidence. Moreover, the chi-square analysis demonstrated that health insurance ownership (OR = 4.473; 95% CI 1.824-10.972; p ≤ 0.001), history of hypertension (OR = 3.096; 95% CI 1.542-6.218; p=0.001), and history of gout (OR = 2.419; 95% CI 1.148-5.099; p=0.018), were associated with prediabetes incidence. For all these significant risk predictors except BMI, the significant associations were found only among female subjects after specific sex analysis. Moreover, multivariate logistic regression showed that health insurance ownerships (OR = 5.956; 95% CI 2.256-15.661; p ≤ 0.001) and history of hypertension (OR = 3.257; 95% CI 1.451-7.311; p=0.004), and systolic blood pressure (OR = 2.141; 95% CI 1.092-4.196; p=0.027) were the risk factors for prediabetes. It is concluded that the prevalence of prediabetes is probably high especially among urban people in Pontianak, Indonesia. Health insurance ownership and hypertension may have an important role in prediabetes management. The risk factors might be different between male and female.

Abstract
Objective: The PreventionLink of Southern Maryland is a 5-year project to eliminate
barriers to participation and retention in the National Diabetes Prevention
Program (DPP) lifestyle change program to prevent or delay the onset of type
2 diabetes in adults with prediabetes. This is the study to identify the
obstacles to participation and retention in the DPP lifestyle change program
among high burden populations and learn how CHWs have reduced the identified
barriers to participation and retention for high burden populations. Methods: We followed the Preferred Reporting Items for Systematic Reviews and
Meta-Analyses (PRISMA) to conduct this literature review. We have used the
Scopus and PubMed, including all types of studies and peer-reviewed
documents published in English between 2010 and 2020. Results: From 131 identified articles, 18 articles were selected for qualitative
synthesis. The reviewed literature documented following as main barriers to
participate in a DPP lifestyle change program: time, cost, lack of
transportation, cost of transportation, commute distance, technology access,
access to facilities and community programs, caregiver responsibilities,
lack of health literacy and awareness, and language. CHWs can address these
barriers to participation and retention, they were involved in educating and
supporting roles; they worked as bridges between healthcare providers and
participants and as intervention team members. Conclusions: Diabetes prevention program participants with social determinant risk factors
who most need CHW services are unlikely to have financial resources to pay
for CHW services out-of-pocket. Hence, the public and private health plans
that pay for their prediabetes care should consider paying for these CHW
services and there is a need to trust more to CHW and have them as a
“community health teams” member.

Effects of a Mediterranean diet on the development of diabetic complications: A longitudinal study from the nationwide diabetes report of the National Program for Prevention and Control of Diabetes (NPPCD 2016-2020). Maturitas 2021; 153:61-67. [PMID: 34654529 DOI: 10.1016/j.maturitas.2021.08.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Revised: 08/10/2021] [Accepted: 08/18/2021] [Indexed: 02/08/2023]
Abstract
OBJECTIVE To evaluate the effectiveness of a Mediterranean dietary pattern on the incidence of macrovascular and microvascular complications of diabetes, namely cardiovascular disease (CVD), diabetic foot disorders, diabetic retinopathy, nephropathy, and neuropathy. METHODS This longitudinal study was conducted among 71392 adults with diabetes who attended academic tertiary-care outpatient clinics from February 2016 to March 2020 across Iran using the National Program for Prevention and Control of Diabetes database. Among them, 22187 patients with diabetes (type 1 and type 2) completed 2-11 follow-up visits after baseline registration. The association between adherence to a Mediterranean diet and diabetic complications was assessed using pooled logistic regression models. This association was adjusted for potential confounders. The effect of time was assessed using fractional polynomials. RESULTS A total of 22187 participants were included in the analysis (30.22% men and 69.78% women) with either type 1 (mean age 50.7 years) or type 2 (mean age 59.9 years) diabetes. After adjustment for confounding variables, there was a negative correlation between adherence to a Mediterranean diet and the incidence of CVD among patients with type 1 diabetes (T1D) and 2 diabetes (T2D) (OR= 0.53, 95% CI: 0.37 - 0.75, p-value <0.001 and OR= 0.61, 95% CI: 0.57 - 0.89, p-value <0.001, respectively). Also, the diet had a statistically significant protective effect against incident symptomatic neuropathy (OR= 0.32, 95% CI: 0.23 - 0.43, p-value <0.001, and OR= 0.68, 95% CI: 0.64 - 0.72, p-value <0.001, respectively), nephropathy (OR= 0.42, 95% CI: 0.30 - 0.58, p-value <0.001, and OR= 0.88, 95% CI: 0.80 - 0.96, p-value= 0.007, respectively), and retinopathy (OR= 0.32, 95% CI: 0.24 - 0.44, p-value <0.001, and OR= 0.68, 95% CI: 0.61 - 0.71, p-value <0.001, respectively) in T1D and T2D. CONCLUSION The Mediterranean dietary pattern is associated with a lower incidence of CVD and microvascular complications (i.e. diabetic retinopathy, nephropathy, and neuropathy) among a cohort of patients with T1D and T2D in Iran.

Abstract
Latinxs immigrants in the United States experience sources of stress (i.e., stressors) that can limit their ability to engage in healthy behaviors. Stress has been linked to increased type 2 diabetes (T2D) risk in Latinxs living with prediabetes, a group disproportionately affected by T2D. The purpose of this qualitative study is to describe and contextualize the variety of stressors experienced by Latinxs immigrants diagnosed with prediabetes. Semi-structured, in-depth interviews were conducted from March to September 2018 with 20 Latinx immigrants living with prediabetes in North Carolina. We used qualitative content analysis including systematic coding and comparative matrices. The most prominent stressors were those related to health status and healthcare access, finances, interpersonal relationships with family, and loneliness. Participants also identified stressors related to documentation status and discrimination. The stressors Latinx immigrants with prediabetes experience vary, therefore studies and interventions need to specify which sources of stress they are addressing. Multilevel interventions that ameliorate the effects of stressors may facilitate preventive health behaviors among Latinxs with prediabetes.

Evaluating interventions to delay the progression of prediabetes to type-2 diabetes mellitus in an uninsured Hispanic population. J Am Assoc Nurse Pract 2020; 33:661-666. [PMID: 32649384 DOI: 10.1097/jxx.0000000000000444] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2019] [Accepted: 04/09/2020] [Indexed: 01/31/2023]
Abstract
BACKGROUND Diabetes is a chronic progressive disease affecting 34 million Americans. The Centers for Disease Control and Prevention estimates that 12.5% of people aged 20 years or older diagnosed with diabetes are Hispanic. The American Diabetes Association further estimates that 84.1 million Americans aged 20 years and older have prediabetes based on fasting blood sugar and hemoglobin A1c (HbA1c) levels alone. LOCAL PROBLEM In Georgia, the overall rate of diagnosed diabetes is 9.7%, undiagnosed is 6.5%, and prediabetes is 1.1%. The prevalence of diabetes for the Hispanic population in Georgia is 9% and is 10% among Clayton County residents. The purpose of this quality improvement project (QIP) was to evaluate interventions implemented to delay the progressions of prediabetes to type-2 diabetes in an uninsured Hispanic population. METHODS Retrospective chart review was conducted comparing pre- and postmeasurements for HbA1c and body mass index (BMI) in Hispanic patients identified as having prediabetes. INTERVENTIONS Patients with HbA1c of 5.7-6.1% were provided with a diabetes tool kit, whereas patients with an HbA1c of 6.2-6.4% were given the diabetes tool kit plus metformin. RESULTS A decrease in mean HbA1c was noted in both groups of patients. However, a paired sample t-test indicated nonsignificant decrease in HbA1c for the diabetes tool kit group (p = .51) but significant decrease for the diabetes tool group kit plus metformin group (p < .01). CONCLUSIONS Although this QIP did not reveal statistically significant changes in HbA1c and BMI for both groups, the results were clinically significant among this Hispanic population.

Abstract
BACKGROUND Feel4Diabetes was a school and community based intervention aiming to promote healthy lifestyle and tackle obesity for the prevention of type 2 diabetes among families in 6 European countries. We conducted this literature review in order to guide the development of evidence-based implementation of the Feel4Diabetes intervention. We focused on type 2 diabetes prevention strategies, including all the phases from risk identification to implementation and maintenance. Special focus was given to prevention among vulnerable groups and people under 45 years. METHODS Scientific and grey literature published between January 2000 and January 2015 was searched for relevant studies using electronic databases. To present the literature review findings in a systematic way, we used the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. A complementary literature search from February 2015 to December 2018 was also conducted. RESULTS The initial review included 27 studies with a follow-up ≥12 months and 9 studies with a follow-up ≥6 months and with a participant mean age < 45 years. We found out that interventions should be targeted at people at risk to improve recruiting and intervention effectiveness. Screening questionnaires (primarily Finnish Diabetes Risk Score FINDRISC) and blood glucose measurement can both be used for screening; the method does not appear to affect intervention effectiveness. Screening and recruitment is time-consuming, especially when targeting lower socioeconomic status and age under 45 years. The intervention intensity is more important for effectiveness than the mode of delivery. Moderate changes in several lifestyle habits lead to good intervention results. A minimum of 3-year follow-up seemed to be required to show a reduction in diabetes risk in high-risk individuals. In participants < 45 years, the achieved results in outcomes were less pronounced. The complementary review included 12 studies, with similar results regarding intervention targets and delivery modes, as well as clinical significance. CONCLUSION This narrative review highlighted several important aspects that subsequently guided the development of the Feel4Diabetes high-risk intervention. Research on diabetes prevention interventions targeted at younger adults or vulnerable population groups is still relatively scarce. Feel4Diabetes is a good example of a project aiming to fill this research gap. TRIAL REGISTRATION clinicaltrials.gov NCT02393872, registered 20th March 2015.

Abstract
BACKGROUND The projected rise in the incidence of type 2 diabetes mellitus (T2DM) could develop into a substantial health problem worldwide. Whether metformin can prevent or delay T2DM and its complications in people with increased risk of developing T2DM is unknown. OBJECTIVES To assess the effects of metformin for the prevention or delay of T2DM and its associated complications in persons at increased risk for the T2DM. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials, MEDLINE, Scopus, ClinicalTrials.gov, the World Health Organization (WHO) International Clinical Trials Registry Platform and the reference lists of systematic reviews, articles and health technology assessment reports. We asked investigators of the included trials for information about additional trials. The date of the last search of all databases was March 2019. SELECTION CRITERIA We included randomised controlled trials (RCTs) with a duration of one year or more comparing metformin with any pharmacological glucose-lowering intervention, behaviour-changing intervention, placebo or standard care in people with impaired glucose tolerance, impaired fasting glucose, moderately elevated glycosylated haemoglobin A1c (HbA1c) or combinations of these. DATA COLLECTION AND ANALYSIS Two review authors read all abstracts and full-text articles and records, assessed risk of bias and extracted outcome data independently. We used a random-effects model to perform meta-analysis and calculated risk ratios (RRs) for dichotomous outcomes and mean differences (MDs) for continuous outcomes, using 95% confidence intervals (CIs) for effect estimates. We assessed the certainty of the evidence using GRADE. MAIN RESULTS We included 20 RCTs randomising 6774 participants. One trial contributed 48% of all participants. The duration of intervention in the trials varied from one to five years. We judged none of the trials to be at low risk of bias in all 'Risk of bias' domains. Our main outcome measures were all-cause mortality, incidence of T2DM, serious adverse events (SAEs), cardiovascular mortality, non-fatal myocardial infarction or stroke, health-related quality of life and socioeconomic effects.The following comparisons mostly reported only a fraction of our main outcome set. Fifteen RCTs compared metformin with diet and exercise with or without placebo: all-cause mortality was 7/1353 versus 7/1480 (RR 1.11, 95% CI 0.41 to 3.01; P = 0.83; 2833 participants, 5 trials; very low-quality evidence); incidence of T2DM was 324/1751 versus 529/1881 participants (RR 0.50, 95% CI 0.38 to 0.65; P < 0.001; 3632 participants, 12 trials; moderate-quality evidence); the reporting of SAEs was insufficient and diverse and meta-analysis could not be performed (reported numbers were 4/118 versus 2/191; 309 participants; 4 trials; very low-quality evidence); cardiovascular mortality was 1/1073 versus 4/1082 (2416 participants; 2 trials; very low-quality evidence). One trial reported no clear difference in health-related quality of life after 3.2 years of follow-up (very low-quality evidence). Two trials estimated the direct medical costs (DMC) per participant for metformin varying from $220 to $1177 versus $61 to $184 in the comparator group (2416 participants; 2 trials; low-quality evidence). Eight RCTs compared metformin with intensive diet and exercise: all-cause mortality was 7/1278 versus 4/1272 (RR 1.61, 95% CI 0.50 to 5.23; P = 0.43; 2550 participants, 4 trials; very low-quality evidence); incidence of T2DM was 304/1455 versus 251/1505 (RR 0.80, 95% CI 0.47 to 1.37; P = 0.42; 2960 participants, 7 trials; moderate-quality evidence); the reporting of SAEs was sparse and meta-analysis could not be performed (one trial reported 1/44 in the metformin group versus 0/36 in the intensive exercise and diet group with SAEs). One trial reported that 1/1073 participants in the metformin group compared with 2/1079 participants in the comparator group died from cardiovascular causes. One trial reported that no participant died due to cardiovascular causes (very low-quality evidence). Two trials estimated the DMC per participant for metformin varying from $220 to $1177 versus $225 to $3628 in the comparator group (2400 participants; 2 trials; very low-quality evidence). Three RCTs compared metformin with acarbose: all-cause mortality was 1/44 versus 0/45 (89 participants; 1 trial; very low-quality evidence); incidence of T2DM was 12/147 versus 7/148 (RR 1.72, 95% CI 0.72 to 4.14; P = 0.22; 295 participants; 3 trials; low-quality evidence); SAEs were 1/51 versus 2/50 (101 participants; 1 trial; very low-quality evidence). Three RCTs compared metformin with thiazolidinediones: incidence of T2DM was 9/161 versus 9/159 (RR 0.99, 95% CI 0.41 to 2.40; P = 0.98; 320 participants; 3 trials; low-quality evidence). SAEs were 3/45 versus 0/41 (86 participants; 1 trial; very low-quality evidence). Three RCTs compared metformin plus intensive diet and exercise with identical intensive diet and exercise: all-cause mortality was 1/121 versus 1/120 participants (450 participants; 2 trials; very low-quality evidence); incidence of T2DM was 48/166 versus 53/166 (RR 0.55, 95% CI 0.10 to 2.92; P = 0.49; 332 participants; 2 trials; very low-quality evidence). One trial estimated the DMC of metformin plus intensive diet and exercise to be $270 per participant compared with $225 in the comparator group (94 participants; 1 trial; very-low quality evidence). One trial in 45 participants compared metformin with a sulphonylurea. The trial reported no patient-important outcomes. For all comparisons there were no data on non-fatal myocardial infarction, non-fatal stroke or microvascular complications. We identified 11 ongoing trials which potentially could provide data of interest for this review. These trials will add a total of 17,853 participants in future updates of this review. AUTHORS' CONCLUSIONS Metformin compared with placebo or diet and exercise reduced or delayed the risk of T2DM in people at increased risk for the development of T2DM (moderate-quality evidence). However, metformin compared to intensive diet and exercise did not reduce or delay the risk of T2DM (moderate-quality evidence). Likewise, the combination of metformin and intensive diet and exercise compared to intensive diet and exercise only neither showed an advantage or disadvantage regarding the development of T2DM (very low-quality evidence). Data on patient-important outcomes such as mortality, macrovascular and microvascular diabetic complications and health-related quality of life were sparse or missing.

Abstract
INTRODUCTION We examined the effects of a digitally delivered, type 2 diabetes mellitus prevention program (DPP) for a low-income population. METHODS We conducted a nonrandomized clinical trial with matched controls. The intervention group was offered a digital DPP, a web-based and mobile-based program including 52 weeks of participation in an educational curriculum, health coaching, and peer support. RESULTS A total of 227 participants enrolled. At baseline, 34.6 was the mean body mass index, and 5.8 was the mean HbA1c. For the intervention group, mean weight loss was 4.4% at the 12-month follow-up. CONCLUSION The modified DPP successfully engaged participants and resulted in weight loss. Low-income patients with prediabetes benefitted from a digitally delivered diabetes intervention. This prevention method should be accessible to a low-income population.

Abstract
To compare cardiovascular risk and disease prevalence in U.S. Hispanics/Latinas with and without a history of gestational diabetes mellitus (GDM). Cross-sectional data from 2008 to 2011 were analyzed for 8,262 (305 with GDM history) parous women, aged 20-73 years, from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). Women with and without a history of GDM were compared on sociodemographic, cardiovascular risk factor, and disease data from standardized interviews and fasting blood tests, using chi-square tests, t-tests, and logistic regressions to determine odds ratios (ORs) and 95 percent confidence intervals (CIs). Adjusting for covariates, compared to those without a history of GDM, women with a history of GDM were younger (M = 39.1 years [95 percent CI = 37.8, 41.6] vs. 45.5 years [95 percent CI = 44.9, 46.1]) and more likely to have health insurance (68.1 percent [95 percent CI = 60.3 percent, 76.0 percent] vs. 54.9 percent [95 percent CI = 52.8 percent, 57.1 percent]), had greater waist circumference (M = 102.3 cm, [95 percent CI = 100.2, 104.3] vs. 98.1 cm [95 percent CI = 97.4, 98.5]) and higher fasting glucose (116.0 mg/dL [95 percent CI = 107.8, 124.3] vs. 104.2 mg/dL [95 percent CI = 103.4, 105.1]), and had higher odds of having metabolic syndrome (OR = 1.7 [95 percent CI = 1.2, 2.6]) or diabetes (OR = 3.3 [95 percent CI = 2.2, 4.8]). Prevalences of heart and cerebrovascular disease were similar. GDM history was positively associated with diabetes but not with cardiovascular disease.

Contemp Clin Trials 2018; 69:76-82. [PMID: 29654929 DOI: 10.1016/j.cct.2018.04.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2017] [Revised: 04/02/2018] [Accepted: 04/08/2018] [Indexed: 11/23/2022]
Abstract
BACKGROUND Uncontrolled hypertension is a significant public health problem in the U.S. with about one half of people able to keep blood pressure (BP) under control. Uncontrolled hypertension leads to increased risk of stroke, heart attack, and death. Furthermore, the social and economic costs of poor hypertension control are staggering. People living with hypertension can benefit from additional educational outreach and support. METHODS This randomized trial conducted at two Community Health Centers (CHCs) in Massachusetts assessed the effect of community health workers (CHWs) assisting patients with hypertension. In addition to the support provided by CHWs, the study uses video narratives from patients who have worked to control their BP through diet, exercise, and better medication adherence. Participants enrolled in the study were randomly assigned to immediate intervention (I) by CHWs or a delayed intervention (DI) (4 to 6 months later). Each participant was asked to meet with the CHW 5 times (twice in person and three times telephonically). Study outcomes include systolic and diastolic BP, diet, exercise, and body mass index. CONCLUSION CHWs working directly with patients, using multiple approaches to support patient self-management, can be effective agents to support change in chronic illness management. Moreover, having culturally appropriate tools, such as narratives available through videos, can be an important, cost effective aid to CHWs. Recruitment and intervention delivery within a busy CHC environment required adaptation of the study design and protocols for staff supervision, data collection and intervention delivery and lessons learned are presented.

Abstract
Previous studies have shown that lifestyle modification can successfully prevent or delay development of type 2 diabetes. This trial aimed to test if an underserved, low-income population would engage in a digital diabetes prevention program and successfully achieve lifestyle changes to reduce their risk of type 2 diabetes. Participants were recruited from three health care facilities serving low-income populations. The inclusion criteria were: a recent blood test indicating prediabetes, body mass index (BMI) > 24 kg/m2, age 18-75 years, not pregnant, not insured, Medicaid insured or Medicaid-eligible, internet or smartphone access, and comfort reading and writing in English or Spanish. A total of 230 participants were enrolled and started the intervention. Participants' average age was 48 years, average BMI = 34.8, average initial HbA1c = 5.8, 81% were female, and 45% were Spanish speaking. Eighty percent had Medicaid insurance, 18% were uninsured, and 2% were insured by a medical safety net plan. Participants completed a health assessment including measured anthropometrics, HbA1c test, and self-report questionnaires at baseline, 6 and 12 months. The 52-week digital diabetes prevention program included weekly educational curriculum, human health coaching, connected tracking tools, and peer support from a virtual group. Qualitative data on implementation was collected with semi-structured interviews with key informants to understand the barriers, keys to success, and best practices in the adoption of the program within the clinical setting. This paper describes the study design and methodology of a digital diabetes prevention program and early lessons learned related to recruitment, enrollment, and data collection.

Abstract
Objective This study examined changes in mental health symptoms and weight during weight loss treatment. It was hypothesized that worsening mental health would negatively impact weight loss. Methods Data were analyzed from a trial of 92 Hispanic women with overweight/obesity and prediabetes, who were randomized to receive intensive lifestyle intervention (ILI), metformin 1,700 mg daily, or standard care. Depression, anxiety and perceived stress were assessed at 0, 6 and 12 months. Six‐ and 12‐month weight change was compared among participants whose symptom scores worsened on any mental health measure (W) vs. improved or remained stable on all three (I/S). Results Among ILI participants, the 12‐month difference in weight loss between I/S and W groups was statistically significant: −5.1 kg (P = 0.001). From baseline to 6 months, ILI participants in I/S and W groups experienced comparable weight loss. However, from 6 to 12 months, W participants regained weight, whereas I/S participants experienced continued weight loss. In the metformin and standard care arms, there was no weight difference between I/S and W groups. Conclusions In ILI, 12‐month improvement or stability in mental health was significantly associated with weight loss. Weight trajectories between I/S and W groups diverged at 6 months.

Abstract
OBJECTIVE Numerous validated questionnaires use self-reported data to quantify individuals' risk of having diabetes or developing it in the future. Evaluations of these tools have primarily used nationally representative data, limiting their application in clinical and community settings. This analysis tested the effectiveness of the American Diabetes Association (ADA) risk questionnaire for identifying prediabetes in a community-based sample of Latinas. METHODS Data were collected using the ADA risk questionnaire and assessing A1C. Among 204 participants without diabetes, we examined the association between individual characteristics and glycemic status. We then calculated the performance characteristics (sensitivity, specificity, positive predictive value [PPV], and negative predictive value [NPV]) of the ADA risk questionnaire for detecting prediabetes, using A1C results as the gold standard to define the outcome. RESULTS All participants were women of self-reported Hispanic/Latino ethnicity. Their mean ADA risk score was 5.6 ± 1.6. Latinas who had prediabetes were older, with significantly higher rates of hypertension and a higher ADA risk score than those without prediabetes. At a risk score ≥5-the threshold for high risk set by the ADA-the questionnaire had the following test performance characteristics: sensitivity 77.8%, specificity 41.7%, PPV 76.2%, and NPV 43.9%. CONCLUSION The ADA risk questionnaire demonstrates reasonable performance for identifying prediabetes in a community-based sample of Latinas. Our data may guide other groups' use of this tool in the same target population. Future research should examine the effectiveness of this questionnaire for recruiting diverse populations into diabetes prevention programs. In addition, unique diabetes risk assessment tools for specific target populations are needed and may outperform questionnaires developed using nationally representative data.

Abstract
AIM To examine the characteristics of community health workers (CHWs) involved in diabetes prevention programmes (DPPs) and their contributions to expected outcomes. METHODS Electronic databases including PubMed-MEDLINE, EBSCOHost, and SCOPUS/EMBASE were searched for studies published between January 2000 and March 2016. All studies that used CHWs to implement DPP in ≥18-year-old participants without diabetes but at high risk for developing the condition, irrespective of the study design, setting or outcomes measured, were included. Results were synthesized narratively. RESULTS Forty papers of 30 studies were identified. Studies were mainly community-based and conducted in minority populations in USA. Sample sizes ranged from 20 participants in a single community to 2369 participants in 46 communities. Although CHWs were generally from the local community, their qualifications, work experience and training received differed across studies. Overall the training was culturally sensitive and/or appropriate, covering topics such as the importance of good nutrition and the benefits of increased physical activity, communication and leadership. CHWs delivered a variety of interventions and also screened or recruited participants. The shared culture and language between CHWs and participants likely contributed to better programme implementation and successful outcomes. CONCLUSIONS The complexity of DPPs and the diverse CHW roles preclude attributing specific outcomes to CHW involvement. Nevertheless, documenting potential CHW roles and the relevant training required may optimise CHW contributions and facilitate their involvement in DPPs in the future.

Abstract
Prediabetes can be defined by the presence of impaired fasting glucose (IFG) and/or impaired glucose tolerance (IGT), or glycated haemoglobin (HbA1c) to identify individuals at increased risk of developing type 2 diabetes (T2D). The World Health Organization (WHO, 1999) and the American Diabetes Association (ADA, 2003) utilise different cut-off values for IFG (WHO: 6.1–6.9 mmol/L; ADA: 5.6–6.9 mmol/L) but the same cut-off values for IGT (7.8–11.0 mmol/L). This review investigates whether there are differences in prevalence of IFG, IGT, and combined IFG&IGT between ethnicities, in particular Asian Chinese and European Caucasians. In total, we identified 19 studies using the WHO1999 classification, for which the average proportional prevalence for isolated (i)-IFG, i-IGT, and combined IFG&IGT were 43.9%, 41.0%, and 13.5%, respectively, for Caucasian and 29.2%, 49.4%, and 18.2%, respectively, for Asian. For the 14 studies using ADA2003 classification, the average proportional i-IFG, i-IGT, and combined IFG&IGT prevalences were 58.0%, 20.3%, and 19.8%, respectively, for Caucasian; 48.1%, 27.7%, and 20.5%, respectively, for Asian. Whilst not statistically different, there may be clinically relevant differences in the two populations, with our observations for both classifications indicating that prevalence of i-IFG is higher in Caucasian cohorts whilst i-IGT and combined IFG&IGT are both higher in Asian cohorts.

Abstract
PURPOSE OF REVIEW Multi-sector partnerships are broadly considered to be of value for diabetes prevention and management. The purpose of this article is to summarize academic and government collaborations focused on diabetes prevention and management. RECENT FINDINGS Using a narrative review approach, we identified 17 articles describing 10 academic and government partnerships for diabetes management and surveillance. Challenges and gaps in the literature include complexity of diabetes management vis a vis current healthcare infrastructure; a paucity of racial/ethnic diversity in translational efforts; and the time/effort needed to maintain strong relationships across partner institutions. Academic and government partnerships are of value for diabetes prevention and management activities. Acknowledgment that the key priorities of government programming are often costs and feasibility is critical for collaborations to be successful. Future translational efforts of diabetes prevention and management programs should focus on the following: (1) expansion of partnerships between academia and local health departments; (2) increased utilization of implementation science for enhanced and efficient implementation and dissemination; and (3) harnessing of technological advances for data analysis, patient communication, and report generation.

Abstract
INTRODUCTION Although the Diabetes Prevention Program and other clinical trials demonstrated the efficacy of intensive lifestyle interventions (ILI) and metformin to prevent type 2 diabetes, no studies have tested their comparative effects in pragmatic settings. This study was designed to compare the real-world effectiveness of ILI, metformin, and standard care among Hispanic women (Latinas) with prediabetes. STUDY DESIGN RCT. SETTING/PARTICIPANTS Ninety-two Latinas, who had a mean hemoglobin A1c of 5.9%, BMI of 33.3 kg/m2, and waist circumference of 97.4 cm (38.3 inches), were recruited from an urban community and randomly assigned to ILI, metformin, or standard care using 1:1:1 allocation. Data were collected from 2013-2015 and analyzed in 2016. INTERVENTION The 12-month ILI was adapted from the Diabetes Prevention Program's ILI and delivered by community health workers (promotoras) over 24 sessions. Metformin participants received 850 mg twice daily. Those randomized to standard care continued their regular medical care. MAIN OUTCOME MEASURES Weight and secondary outcomes (waist circumference, blood pressure, hemoglobin A1c, fasting plasma glucose, insulin, and lipids) were assessed at baseline and 12 months. RESULTS ILI participants demonstrated significantly greater mean weight loss (-4.0 kg, 5.0%) than metformin (-0.9 kg, 1.1%) and standard care participants (+0.8 kg, 0.9%) (p<0.001). The difference in weight loss between metformin and standard care was not significant. The ILI group experienced a greater reduction in waist circumference than standard care (p=0.001), and a marginal improvement in hemoglobin A1c compared with metformin and standard care (p=0.063). CONCLUSIONS In the first comparative effectiveness trial of diabetes prevention treatments, a 12-month ILI produced significantly greater weight loss than metformin and standard care among Latinas with prediabetes. These data suggest that ILI delivered by promotoras is an effective strategy for preventing diabetes in this high-risk group, which may be superior to metformin. Future pragmatic trials involving larger samples should examine differences in diabetes incidence associated with these treatments.
