Opioid prescription and diabetes among Medicare beneficiaries. Diabetes Res Clin Pract 2023; 196:110240. [PMID: 36610545 PMCID: PMC9974602 DOI: 10.1016/j.diabres.2023.110240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 11/21/2022] [Accepted: 01/03/2023] [Indexed: 01/05/2023]
Abstract
AIMS To determine the prevalence of opioid prescriptions among U.S. Medicare beneficiaries by diabetes status, and predictors of opioid prescription among those with diabetes. METHODS This retrospective study used claims data from the Centers for Medicare and Medicaid Services among beneficiaries age ≥ 65 years who were continuously enrolled in Part A, Part B, and Part D Medicare between 2017 and 2019 (N = 709,374). Logistic regression was used to determine the odds of opioid prescription among those with vs without diabetes; and, among those with diabetes, significant predictors of opioid prescription. RESULTS Overall, the prevalence of any opioid prescription was 30.8 % among persons with diabetes and 24.2 % in those without diabetes (p < 0.001); chronic use was 8.0 % and 7.4 %, respectively (p < 0.001). Those with diabetes had a 45 % higher odds of having an opioid prescription compared to those without diabetes after adjusting for sociodemographic characteristics (OR = 1.45, 1.44-1.47). After adjustment for comorbidities/complications, the association reversed (OR = 0.83, 0.82-0.84). Persons with diabetes who had hypertension, obesity, CVD, neuropathy, amputation, liver disease, COPD, cancer, osteoporosis, depression, or alcohol/drug abuse had a 20 %-140 % higher odds of opioid prescription compared to those without these conditions. CONCLUSIONS Comorbidities and complications accounted for the higher odds of opioid prescriptions among those with diabetes.

Abstract
IMPORTANCE The lower risk of cardiovascular disease (CVD) among women compared with men in the general population may be diminished among those with diabetes. OBJECTIVE To evaluate cardiometabolic risk factors and their management in association with CVD events in women vs men with type 1 diabetes enrolled in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) study. DESIGN, SETTING, AND PARTICIPANTS This cohort study used data obtained during the combined DCCT (randomized clinical trial, conducted 1983-1993) and EDIC (observational study, conducted 1994 to present) studies through April 30, 2018 (mean [SD] follow-up, 28.8 [5.8] years), at 27 clinical centers in the US and Canada. Data analyses were performed between July 2021 and April 2022. EXPOSURE During the DCCT phase, patients were randomized to intensive vs conventional diabetes therapy. MAIN OUTCOMES AND MEASURES Cardiometabolic risk factors and CVD events were assessed via detailed medical history and focused physical examinations. Blood and urine samples were assayed centrally. CVD events were adjudicated by a review committee. Linear mixed models and Cox proportional hazards models evaluated sex differences in cardiometabolic risk factors and CVD risk over follow-up. RESULTS A total of 1441 participants with type 1 diabetes (mean [SD] age at DCCT baseline, 26.8 [7.1] years; 761 [52.8%] men; 1390 [96.5%] non-Hispanic White) were included. Over the duration of the study, compared with men, women had significantly lower body mass index (BMI, calculated as weight in kilograms divided by height in meters squared; β = -0.43 [SE, 0.16]; P = .006), waist circumference (β = -10.56 cm [SE, 0.52 cm]; P < .001), blood pressure (systolic: β = -5.77 mm Hg [SE, 0.35 mm Hg]; P < .001; diastolic: β = -3.23 mm Hg [SE, 0.26 mm Hg]; P < .001), and triglyceride levels (β = -10.10 mg/dL [SE, 1.98 mg/dL]; P < .001); higher HDL cholesterol levels (β = 9.36 mg/dL [SE, 0.57 mg/dL]; P < .001); and similar LDL cholesterol levels (β = -0.76 mg/dL [SE, 1.22 mg/dL]; P = .53). Women, compared with men, achieved recommended targets more frequently for blood pressure (ie, <130/80 mm Hg: 90.0% vs 77.4%; P < .001) and triglycerides (ie, <150 mg/dL: 97.3% vs 90.5%; P < .001). However, sex-specific HDL cholesterol targets (ie, ≥50 mg/dL for women, ≥40 mg/dL for men) were achieved less often (74.3% vs 86.6%; P < .001) and cardioprotective medications were used less frequently in women than men (ie, angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker: 29.6% [95% CI, 25.7%-33.9%] vs 40.0% [95% CI, 36.1%-44.0%]; P = .001; lipid-lowering medication: 25.3% [95% CI, 22.1%-28.7%] vs 39.6% [95% CI, 36.1%-43.2%]; P < .001). Women also had significantly higher pulse rates (mean [SD], 75.2 [6.8] beats per minute vs 71.8 [6.9] beats per minute; P < .001) and hemoglobin A1c levels (mean [SD], 8.3% [1.0%] vs 8.1% [1.0%]; P = .01) and achieved targets for tighter glycemic control less often than men (ie, hemoglobin A1c <7%: 11.2% [95% CI, 9.3%-13.3%] vs 14.0% [95% CI, 12.0%-16.3%]; P = .03). CONCLUSIONS AND RELEVANCE These findings suggest that despite a more favorable cardiometabolic risk factor profile, women with type 1 diabetes did not have a significantly lower CVD event burden than men, suggesting a greater clinical impact of cardiometabolic risk factors in women vs men with diabetes. These findings call for conscientious optimization of the control of CVD risk factors in women with type 1 diabetes.

Diabetes Incidence Among Hispanic/Latino Adults in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). Diabetes Care 2022; 45:1482-1485. [PMID: 35506707 PMCID: PMC9210863 DOI: 10.2337/dc21-1543] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Accepted: 03/25/2022] [Indexed: 02/03/2023]
Abstract
OBJECTIVE To examine diabetes incidence in a diverse cohort of U.S. Hispanic/Latinos. RESEARCH DESIGN AND METHODS The Hispanic Community Health Study/Study of Latinos is a prospective cohort study with participants aged 18-74 years from four U.S. metropolitan areas. Participants were assessed for diabetes at the baseline examination (2008-2011), annually via telephone interview, and at a second examination (2014-2017). RESULTS A total of 11,619 participants returned for the second examination. The overall age-adjusted diabetes incidence rate was 22.1 cases/1,000 person-years. The incidence was high among those with Puerto Rican and Mexican backgrounds as well as those aged ≥45 years and with a BMI ≥30 kg/m2. Significant differences in diabetes awareness, treatment, and health insurance coverage, but not glycemic control, were observed across Hispanic/Latino background groups, age groups, and BMI categories. CONCLUSIONS Differences in diabetes incidence by Hispanic/Latino background, age, and BMI suggest the susceptibility of these factors.

Risk of Foot Ulcer and Lower-Extremity Amputation Among Participants in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Study. Diabetes Care 2022; 45:357-364. [PMID: 35007329 PMCID: PMC8914413 DOI: 10.2337/dc21-1816] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2021] [Accepted: 11/14/2021] [Indexed: 02/03/2023]
Abstract
OBJECTIVE Intensive glycemic control reduces the risk of kidney, retinal, and neurologic complications in type 1 diabetes (T1D), but whether it reduces the risk of lower-extremity complications is unknown. We examined whether former intensive versus conventional glycemic control among Diabetes Control and Complications Trial (DCCT) participants with T1D reduced the long-term risk of diabetic foot ulcers (DFUs) and lower-extremity amputations (LEAs) in the subsequent Epidemiology of Diabetes Interventions and Complications (EDIC) study. RESEARCH DESIGN AND METHODS DCCT participants (n = 1,441) completed 6.5 years on average of intensive versus conventional diabetes treatment, after which 1,408 were enrolled in EDIC and followed annually over 23 years for DFU and LEA occurrences by physical examination. Multivariable Cox proportional hazard regression models estimated associations of DCCT treatment assignment and time-updated exposures with DFU or LEA. RESULTS Intensive versus conventional glycemic control was associated with a significant risk reduction for all DFUs (hazard ratio 0.77 [95% CI 0.60, 0.97]) and a similar magnitude but nonsignificant risk reduction for first-recorded DFUs (0.78 [0.59, 1.03]) and first LEAs (0.70 [0.36, 1.36]). In adjusted Cox models, clinical neuropathy, lower sural nerve conduction velocity, and cardiovascular autonomic neuropathy were associated with higher DFU risk; estimated glomerular filtration rate <60 mL/min/1.73 m2, albuminuria, and macular edema with higher LEA risk; and any retinopathy and greater time-weighted mean DCCT/EDIC HbA1c with higher risk of both outcomes (P < 0.05). CONCLUSIONS Early intensive glycemic control decreases long-term DFU risk, the most important antecedent in the causal pathway to LEA.

Cognitive function among older adults with diabetes and prediabetes, NHANES 2011-2014. Diabetes Res Clin Pract 2021; 178:108939. [PMID: 34229005 PMCID: PMC8429258 DOI: 10.1016/j.diabres.2021.108939] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 04/06/2021] [Accepted: 06/30/2021] [Indexed: 01/02/2023]
Abstract
AIMS To determine the association between diabetes status, glycemia, and cognitive function among a national U.S. sample of older adults in the 2011-2014 National Health and Nutrition Examinations Surveys. METHODS Among 1,552 adults age ≥ 60 years, linear and multivariable logistic regressions were used to determine the association between diabetes status (diabetes, prediabetes, normoglycemia) and cognitive function [Consortium to Establish a Registry for Alzheimer's Disease-Word Learning (CERAD W-L), Animal Fluency test, Digit Symbol Substitution Test (DSST)]. RESULTS Overall, diabetes was associated with mild cognitive dysfunction. In age-adjusted models, adults with diabetes had significantly poorer performance on the delayed and total word recalls (CERAD W-L) compared to those with normoglycemia (5.8 vs. 6.8 words; p = 0.002 and 24.5 vs. 27.6 words; p < 0.001, respectively); the association was non-significant after adjusting for cardiovascular disease. Among all adults, cognitive function scores decreased with increasing HbA1c for all assessments, but remained significant in the fully adjusted model for the Animal Fluency and DSST [beta coefficient = -0.44;-1.11, p < 0.05, respectively]. As measured by the DSST, the proportion with cognitive impairment was significantly higher for older adults with HbA1c ≥ 8.0% (≥64 mmol/mol) vs. HbA1c < 7.0% (<53 mmol/mol) (14.6% vs. 6.3%, p = 0.04). CONCLUSIONS Dysglycemia, as measured by HbA1c, was associated with poorer executive function and processing speed.

Comparison of several survey-based algorithms to ascertain type 1 diabetes among US adults with self-reported diabetes. BMJ Open Diabetes Res Care 2020; 8:8/2/e001917. [PMID: 33298431 PMCID: PMC7733112 DOI: 10.1136/bmjdrc-2020-001917] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Revised: 11/04/2020] [Accepted: 11/15/2020] [Indexed: 12/20/2022] Open
Abstract
INTRODUCTION Defining type of diabetes using survey data is challenging, although important, for determining national estimates of diabetes. The purpose of this study was to compare the percentage and characteristics of US adults classified as having type 1 diabetes as defined by several algorithms. RESEARCH DESIGN AND METHODS This study included 6331 respondents aged ≥18 years who reported a physician diagnosis of diabetes in the 2016-2017 National Health Interview Survey. Seven algorithms classified type 1 diabetes using various combinations of self-reported diabetes type, age of diagnosis, current and continuous insulin use, and use of oral hypoglycemics. RESULTS The percentage of type 1 diabetes among those with diabetes ranged from 3.4% for those defined by age of diagnosis <30 years and continuous insulin use (algorithm 2) to 10.2% for those defined only by continuous insulin use (algorithm 1) and 10.4% for those defined as self-report of type 1 (supplementary algorithm 6). Among those defined by age of diagnosis <30 years and continuous insulin use (algorithm 2), by self-reported type 1 diabetes and continuous insulin use (algorithm 4), and by self-reported type 1 diabetes and current insulin use (algorithm 5), mean body mass index (BMI) (28.6, 27.4, and 28.5 kg/m2, respectively) and percentage using oral hypoglycemics (16.1%, 11.1%, and 19.0%, respectively) were lower than for all other algorithms assessed. Among those defined by continuous insulin use alone (algorithm 1), the estimates for mean age and age of diagnosis (54.3 and 30.9 years, respectively) and BMI (30.9 kg/m2) were higher than for other algorithms. CONCLUSIONS Estimates of type 1 diabetes using commonly used algorithms in survey data result in varying degrees of prevalence, characteristic distributions, and potential misclassification.

Urinary phenols and parabens and diabetes among US adults, NHANES 2005-2014. Nutr Metab Cardiovasc Dis 2020; 30:768-776. [PMID: 32127337 PMCID: PMC8772274 DOI: 10.1016/j.numecd.2020.01.005] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2019] [Revised: 12/11/2019] [Accepted: 01/04/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND AND AIMS Phenols and parabens are ubiquitous and have been associated with markers of cardiovascular health. However, the literature lacks population-based studies examining the link between these endocrine disruptors and diabetes. We examined the association between paraben/phenol concentrations and diabetes among a nationally representative sample of US adults. METHODS AND RESULTS We utilized data from the 2005-2014 National Health and Nutrition Examination Surveys (N = 8498). Total urinary concentrations of BPA, triclosan, BP-3, and propyl, butyl, ethyl, and methyl parabens were measured from urine specimens collected during the examination session. Diabetes status was based on self-report of a previous diagnosis or HbA1c≥6.5%. We used logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (CI) associated with the difference in log-transformed values of the 75th and 25th percentiles for each phenol/paraben, adjusting for potential confounders. The adjusted ORs (95% CI) of diabetes comparing the 75th to 25th percentiles of each paraben/phenol were 1.09 (0.96-1.23) for BPA, 0.84 (0.72-0.98) for triclosan, 0.69 (0.61-0.79) for BP-3, 0.71 (0.61-0.83) for propyl paraben, 0.66 (0.54-0.80) for butyl paraben, 0.60 (0.51-0.71) for ethyl paraben, and 0.79 (0.68-0.91) for methyl paraben. CONCLUSIONS Higher concentrations of triclosan, BP-3, and propyl, butyl, ethyl, and methyl parabens were associated with lower odds of diabetes. These findings warrant further investigation into the potential mechanism behind the observed associations and the temporal direction of the associations, given that we cannot rule out reverse causation. Future studies of these endocrine disruptors may improve the understanding of their relationship with diabetes.

Abstract
CONTEXT Evidence suggests that heart rate (HR) is a prognostic factor for cardiovascular disease (CVD), for which persons with diabetes are at increased risk. OBJECTIVE The objective of this article is to determine the association between HR and glycemic status in a nationally representative sample of US adults, and, among adults with diagnosed diabetes, the association between HR and hemoglobin A1c (HbA1c) level. DESIGN A cross-sectional study was conducted. SETTING The setting of this study is the National Health and Nutrition Examination Surveys, 2011 to 2016. PARTICIPANTS US general adult (age ≥ 20 years) population who had information on glycemic status based on self-report, HbA1c, and fasting plasma glucose (N = 8562). INTERVENTION There was no intervention. MAIN OUTCOME MEASURE The main outcome measure of this study was mean HR (beats per minute). RESULTS After adjustment for examination time, age, other demographic characteristics, health insurance, health behaviors, body mass index, CVD and kidney disease, and taking antihypertensive medications, mean HR was significantly higher for those with diagnosed (75 bpm), undiagnosed diabetes (75 bpm), and prediabetes (73 bpm) compared to those with normoglycemia (71 bpm, P < .05 for all); this association was robust both for men and women. Mean HR increased with increasing HbA1c level among individuals with diagnosed diabetes independent of other risk factors (HbA1c < 7.0% [< 53 mmol/mol], 73 bpm vs A1c ≥ 11.0% [≥ 97mmol/mol], 79 bpm, P < .001); this association was most pronounced for women. CONCLUSIONS Adjusted mean HR was higher among individuals with diabetes and increased glycemia, which may reflect underlying autonomic and/or myocardial dysfunction among those with diabetes.

Abstract
Objective: Studies have demonstrated that glycated hemoglobin (HbA1c) is a significant predictor of hearing impairment in type 1 diabetes. We identified additional factors associated with hearing impairment in participants with type 1 diabetes from the Diabetes Control and Complications Trial and its observational follow-up, the Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) study. Methods: A total of 1,150 DCCT/EDIC participants were recruited for the Hearing Study. A medical history, physical measurements, and a self-administered hearing questionnaire were obtained. Audiometry was performed by study-certified personnel and assessed centrally. Logistic regression models assessed the association of risk factors and comorbidities with speech- and high-frequency hearing impairment. Results: Mean age was 55 ± 7 years, duration of diabetes 34 ± 5 years, and DCCT/EDIC HbA1c 7.9 ± 0.9% (63 mmol/mol). In multivariable models, higher odds of speech-frequency impairment were significantly associated with older age, higher HbA1c, history of noise exposure, male sex, and higher triglycerides. Higher odds of high-frequency impairment were associated with older age, male sex, history of noise exposure, higher skin intrinsic florescence (SIF) as a marker of tissue glycation, higher HbA1c, nonprofessional/nontechnical occupations, sedentary activity, and lower low-density-lipoprotein cholesterol. Among participants who previously completed computed tomography and carotid ultrasonography, coronary artery calcification (CAC) >0 and carotid intima-medial thickness were significantly associated with high-but not speech-frequency impairment. Conclusion: Consistent with previous reports, male sex, age, several metabolic factors, and noise exposure are independently associated with hearing impairment. The association with SIF further emphasizes the importance of glycemia-as a modifiable risk factor-over time. In addition, the macrovascular contribution of CAC is novel and important.

Abstract
Diabetes is a prevalent condition in the U.S. and worldwide, with expanding impact over time as it affects progressively younger ages as well as older ages as people live longer. Costs of diabetes to those affected and to society as a whole continue to increase. Costs are realized through daily treatment regimens throughout life to control glycemia and other risk factors for complications as diabetes progresses, diabetes complications and disability and their treatments, health care visits and hospitalization, and as indirect costs via lower quality of life and lost productivity. Diagnosing diabetes is key to affording the opportunity to treat diabetes, and diabetes control is key to reducing the risk of complications. Yet the magnitude of undiagnosed diabetes and poor control of diabetes is large. And just as certain subgroups of the population are affected disproportionately by diabetes and diabetes complications, so are they affected disproportionately by undiagnosed diabetes and poor control. This review addresses the epidemiology of undiagnosed diabetes and diabetes control, largely covering their magnitude, demographic variation, trends over time, and predictors. For diabetes control, it focuses on control of A1C, blood pressure, and lipid levels, although there are many other facets of diabetes control and preventive care that also could be examined. The review is based predominantly on data from the National Health and Nutrition Examination Survey (NHANES), a U.S. health survey that includes both an interview and examination component that has been conducted continuously since 1999 and episodically for decades earlier. The interview elicits self-reported health responses pertaining to diabetes and other medical conditions and an examination that measures glycemic indicators, blood pressure, and lipids, which provide much of the material presented herein. Data from other studies are also presented and described.

Abstract
AIMS To investigate sociodemographic and health factors associated with undiagnosed diabetes among adults with diabetes in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). METHODS Among 3384 adults with self-reported diabetes or undiagnosed diabetes in the baseline HCHS/SOL, we estimated odds ratios (OR) of being undiagnosed for demographic, cultural, access to care, and health factors. RESULTS Among individuals with diabetes, 37.0% were undiagnosed. After adjustment and compared to people of Mexican heritage, people of Cuban and South American heritage had 60% (OR = 1.60, 95% CI = 1.02-2.50) and 91% (OR = 1.91, 1.16-3.14) higher odds of being undiagnosed, respectively. Individuals with a higher odds of being undiagnosed were women (OR = 1.64, 1.26-2.13), those with no health insurance (OR = 1.31, 1.00-1.71), individuals who received no healthcare in the past year (OR = 3.59, 2.49-5.16), those who were overweight (vs. normal weight) (OR = 1.60, 1.02-2.50), and those with dyslipidemia (OR = 1.38, 1.10-1.74). Individuals with lower odds of being undiagnosed were those with a family history of diabetes (OR = 0.54, 0.43-0.68), and those with hypertension (OR = 0.46, 0.36-0.58). CONCLUSIONS Variation by Hispanic heritage group, sex, and access to medical care highlight where concentrated efforts are need to improve diabetes awareness. Our findings will inform clinical and public health practices to improve diabetes awareness among vulnerable populations.

Abstract
OBJECTIVE To evaluate the prevalence of hearing impairment in participants with type 1 diabetes enrolled in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications (DCCT/EDIC) study and compare with that of a spousal control group without diabetes. Among participants with type 1 diabetes, to evaluate the association of hearing impairment with prior DCCT therapy and overall glycemia. RESEARCH DESIGN AND METHODS DCCT/EDIC participants (n = 1,150) and 288 spouses without diabetes were recruited for the DCCT/EDIC Hearing Study. All subjects completed a self-administered questionnaire, medical history, and physical measurements. Audiometry was performed by study-certified personnel; audiograms were assessed centrally. Speech-frequency (pure-tone average [PTA] thresholds at 500, 1,000, 2,000, and 4,000 Hz) and high-frequency impairment (PTA thresholds at 3,000, 4,000, 6,000, and 8,000 Hz) were defined as PTA >25 dB hearing loss. Logistic regression models were adjusted for age and sex. RESULTS DCCT/EDIC participants and spousal control subjects were similar in age, race, education, smoking, and systolic blood pressure. There were no statistically significant differences between groups in the prevalence or adjusted odds of speech- or high-frequency impairment in either ear. Among participants with type 1 diabetes, for every 10% increase in the time-weighted mean HbA1c, there was a 32% (95% CI 1.15-1.50) and 19% (95% CI 1.07-1.33) increase in speech- and high-frequency hearing impairment, respectively. CONCLUSIONS We found no significant difference in the prevalence of hearing impairment between the group with type 1 diabetes and the spousal control group. Among those with type 1 diabetes, higher mean HbA1c over time was associated with hearing impairment.

[PMID: 30122354 DOI: 10.1016/j.annepidem.2018.07.012] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2017] [Revised: 07/19/2018] [Accepted: 07/23/2018] [Indexed: 10/28/2022]
Abstract
PURPOSE Our goal was to characterize the contributions of A1c, fasting plasma glucose, and 2-hour plasma glucose to prediabetes prevalence and to characterize how those contributions differ among U.S. population subgroups. METHODS In the 2011-2014 National Health and Nutrition Examination Survey, a nationally representative sample of the U.S. population, among participants without diabetes (N = 3387), we created area-proportional three-Venn diagrams showing the proportion above the prediabetes cutpoint for each of the three markers in the overall population and in subgroups defined by age, race/ethnicity, sex, and body mass index. RESULTS In the overall population, 28.3% had fasting plasma glucose above the prediabetes cutpoint, 21.7% had A1c above the prediabetes cutpoint, and 13.3% had 2-hour plasma glucose above the prediabetes cutpoint. Adolescents and young adults tended to have only one marker exceed the prediabetes cutpoint, while older age groups tended to have multiple markers above the prediabetes cutpoint. For non-Hispanic whites, non-Hispanic blacks, non-Hispanic Asians, and Mexican-Americans, the unadjusted total percent above the A1c cutpoint was 19.3%, 36.4%, 20.5%, and 21.4%, respectively. CONCLUSIONS We provide a graphic reference showing fasting plasma glucose was the largest contributor to prediabetes prevalence in the overall population, followed by A1c and then 2-hour plasma glucose.

Prevalence of gestational diabetes and subsequent Type 2 diabetes among U.S. women. Diabetes Res Clin Pract 2018; 141:200-208. [PMID: 29772286 DOI: 10.1016/j.diabres.2018.05.010] [Citation(s) in RCA: 155] [Impact Index Per Article: 25.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2017] [Revised: 04/13/2018] [Accepted: 05/08/2018] [Indexed: 12/16/2022]
Abstract
AIMS The true prevalence of gestational diabetes (GDM) in the United States is unknown. This study determined the prevalence of GDM and a subsequent diagnosis of diabetes in a nationally representative sample of U.S. women. METHODS The crude and age-adjusted prevalence of GDM and subsequent diabetes were evaluated by sociodemographic and health-related characteristics among women age ≥20 years in the National Health and Nutrition Examination Surveys, 2007-2014 (N = 8185). Logistic regression analyzed independent factors associated with GDM and subsequent diabetes. RESULTS The prevalence of GDM was 7.6%. Women who were Mexican American (vs. non-Hispanic white), had ≥4 live births (vs. 1), had a family history of diabetes, or were obese (vs. normal weight) had a higher age-standardized prevalence of GDM (each p < 0.04). Among women with a history of GDM, 19.7% had a subsequent diagnosis of diabetes; subsequent diabetes diagnosis was higher for those with health insurance, more time since GDM diagnosis, greater parity, family history of diabetes, and obesity, and lower for those with higher education and income (all p ≤ 0.005). By logistic regression, significant factors associated with GDM were age at first birth, parity, family history of diabetes, and obesity; significant factors for subsequent diabetes were older age, greater years since GDM diagnosis, less education, family history of diabetes, and obesity (each p < 0.01). CONCLUSIONS The prevalence of GDM in the U.S. was 7.6%, with 19.7% of these women having a subsequent diabetes diagnosis. Women with a history of GDM, family history of diabetes, and obesity should be carefully monitored for dysglycemia.

Abstract
AIMS Adolescents with Type 2 diabetes are more likely to have cardiovascular disease (CVD) risk factors but there are few data available among adolescents with prediabetes. We characterized CVD risk factors among adolescents with prediabetes in the USA and compared levels of those risk factors with adolescents with normal glucose. METHODS The 2005-2014 National Health and Nutrition Examination Survey, a nationally representative cross-sectional survey, included 2843 adolescents aged 12-19 years after excluding those with diabetes. Prediabetes was based on an HbA1c , a fasting plasma glucose or a 2-h plasma glucose. We determined cardiometabolic risk factors in adolescents using age-appropriate cut-off points. We calculated odds ratios (OR) and 95% confidence intervals (CI) of these outcomes associated with having prediabetes compared with normal glucose levels. RESULTS The weighted prevalence of prediabetes was 17.4%. After adjustment, prediabetes (vs. normal glucose) was associated with obesity (OR 1.86, 95% CI 1.35-2.55), low HDL-cholesterol (OR 1.62, 95% CI 1.08-2.44), high triglycerides (OR 1.61, 95% CI 1.12-2.30) and elevated liver transaminase (OR 2.09, 95% CI 1.19-3.67), but not with hypertension (OR 1.77, 95% CI 0.88-3.54), elevated total cholesterol (OR 1.30, 95% CI 0.82-2.06), elevated LDL-cholesterol (OR 1.59, 95% CI 0.88-2.88) or albuminuria (OR 1.24, 95% CI 0.76-2.02). CONCLUSIONS US adolescents with prediabetes are more likely to have obesity, low HDL-cholesterol, high triglycerides and elevated liver transaminase than adolescents with normal glucose. Addressing prediabetes in youth is important for the prevention of Type 2 diabetes and long-term comorbidity.

Abstract
OBJECTIVE Determine the prevalence of diabetes using 2-h plasma glucose among people who otherwise would be categorized as having prediabetes based on A1c and fasting glucose, and to determine whether those people were more likely to have cardiometabolic risk factors. METHODS Among 3644 adults with prediabetes based on A1c and fasting glucose in the 2005-2014 National Health and Nutrition Examination Survey, a cross-sectional survey of the US general population, we estimated the percentage who would be categorized as having diabetes based on having a 2-h plasma glucose ⩾200 mg/dL. We calculated odds ratios of cardiometabolic risk factors associated with having 2-h plasma glucose ⩾200 mg/dL. RESULTS A total of 6.9% would be categorized as having diabetes based on 2-h plasma glucose. The adjusted odds ratios (95% confidence interval) associated with having 2-h plasma glucose ⩾200 mg/dL were significant for total hypertension (2.06, 1.35-3.14), high triglycerides (1.64, 1.10-2.44), low high-density lipoprotein cholesterol (1.55, 1.01-2.39), albuminuria (2.05, 1.33-3.14) and elevated alanine aminotransferase (1.78, 1.09-2.91), but not for other cardiometabolic risk factors. CONCLUSION A total of 6.9% of people categorized as having prediabetes based on A1c and fasting glucose would be categorized as having diabetes based on 2-h plasma glucose. They were more likely to have hypertension, high triglycerides, low high-density lipoprotein cholesterol, albuminuria and elevated alanine aminotransferase.

Variations of dietary intake by glycemic status and Hispanic/Latino heritage in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). BMJ Open Diabetes Res Care 2018; 6:e000486. [PMID: 29449952 PMCID: PMC5808640 DOI: 10.1136/bmjdrc-2017-000486] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2017] [Revised: 12/11/2017] [Accepted: 12/29/2017] [Indexed: 01/10/2023] Open
Abstract
OBJECTIVE A healthy diet is important for diabetes prevention and control; however, few studies have assessed dietary intake among US Hispanics/Latinos, a diverse population with a significant burden of diabetes. To address this gap in the literature, we determined intake of energy, macro/micronutrients, and vitamin supplements among Hispanics/Latinos by glycemic status and heritage. RESEARCH DESIGN AND METHODS Cross-sectional study of adults aged 18-74 years from the Hispanic Community Health Study/Study of Latinos (2008-2011) with complete baseline data on glycemic status and two 24-hour dietary recalls (n=13 089). Age-adjusted and sex-adjusted and multivariable-adjusted measures of intake were determined by glycemic status and heritage. RESULTS Mean age-adjusted and sex-adjusted energy intake was significantly lower among Hispanics/Latinos with diagnosed diabetes compared with those with normal glycemic status (1665 vs 1873 kcal, P<0.001). Fiber intake was higher among those with diagnosed diabetes versus normal glycemic status (P<0.01). Among those with diagnosed diabetes, energy intake was highest among those with Cuban heritage compared with most other heritage groups (P<0.01 for all, except Mexicans), but there was no difference after additional adjustment. Fiber intake was significantly lower for those of Cuban heritage (vs Dominican, Central American, and Mexican), and sodium intake was significantly higher (vs all other heritage groups) (P<0.01 for all); findings were null after additional adjustment. There was no difference in supplemental intake of vitamin D, calcium, magnesium, or potassium by glycemic status. CONCLUSIONS As part of the care of Hispanics/Latinos with diabetes, attention should be made to fiber and sodium consumption.

Abstract
AIMS Asians develop diabetes at lower levels of adiposity than people of other race/ethnicities. However, there is limited data investigating the health of US Asians with diabetes. We compared cardiovascular risk factors in US Asians to other race/ethnicities stratified by diabetes status. METHODS Among 4645 adults in the 2011-2014 National Health and Nutrition Examination Survey (NHANES), a cross-sectional survey of the US population, odds ratios were calculated for obesity, hypertension, and elevated low-density lipoprotein (LDL) cholesterol associated with race/ethnicity after adjustment for age, sex, income, education, smoking, alcohol consumption, and health insurance. RESULTS Overall and stratified by diabetes status, non-Hispanic whites, non-Hispanic blacks, and Mexican-Americans were significantly more likely to be obese compared to non-Hispanic Asians after adjustment. Overall and stratified by diabetes status, adjusted levels of hypertension compared to non-Hispanic Asians was generally similar for non-Hispanic whites and Mexican-Americans and generally more common among non-Hispanic blacks; among those with diagnosed diabetes, the adjusted odds ratios (95% confidence interval) were 1.48 (0.79-2.77), 2.54 (1.49-4.30), and 1.38 (0.73-2.60) for non-Hispanic whites, non-Hispanic blacks, and Mexican-Americans, respectively. Overall and stratified by diabetes status, elevated LDL cholesterol levels were generally similar between non-Hispanic Asians and other race/ethnicities; among those with diagnosed diabetes, the adjusted odds ratios (95% confidence interval) were 0.88 (0.32-2.43), 0.58 (0.24-1.42), and 1.15 (0.29-4.58) for non-Hispanic whites, non-Hispanic blacks, and Mexican-Americans, respectively. CONCLUSIONS Although non-Hispanic Asians had lower levels of adiposity compared to other race/ethnicities with diabetes, their adjusted levels of hypertension and LDL cholesterol were generally more comparable.

Abstract
OBJECTIVE To determine the prevalence of Hispanic/Latino adults with diabetes who meet target hemoglobin A1c, blood pressure (BP), and low-density-lipoprotein cholesterol (LDL-C) recommendations, and angiotensin-converting enzyme (ACE) inhibitors/angiotensin receptor blocker (ARB) and statin medication use by heritage and sociodemographic and diabetes-related characteristics. METHODS Data were cross-sectional, collected between 2008 and 2011, and included adults age 18 to 74 years who reported a physician diagnosis of diabetes in the Hispanic Community Health Study/Study of Latinos (N = 2,148). Chi-square tests compared the prevalence of hemoglobin A1c, BP, and LDL-C targets and ACE/ARB and statin use across participant characteristics. Predictive margins regression was used to determine the prevalence adjusted for sociodemographic characteristics. RESULTS The overall prevalence of A1c <7.0% (53 mmol/mol), BP <130/80 mm Hg, and LDL-C <100 mg/dL was 43.0, 48.7, and 36.6%, respectively, with 8.4% meeting all three targets. Younger adults aged 18 to 39 years with diabetes were less likely to have A1c <7.0% (53 mmol/mol) or LDL-C <100 mg/dL compared to those aged 65 to 74 years; younger adults were more likely to have BP <130/80 mm Hg (P<.05 for all). Individuals of Mexican heritage were significantly less likely to have A1c <7.0% (53 mmol/mol) compared to those with Cuban heritage, but they were more likely to have BP <130/80 mm Hg compared to those with Dominican, Cuban, or Puerto Rican heritage (P<.05 for all); there was no difference in LDL-C by heritage. Overall, 38.2% of adults with diabetes were taking a statin, and 50.5% were taking ACE/ARB medications. CONCLUSION Hemoglobin A1c, BP, and LDL-C control are suboptimal among Hispanic/Latinos with diabetes living in the U.S. With 8.4% meeting all three recommendations, substantial opportunity exists to improve diabetes control in this population. ABBREVIATIONS A1c = hemoglobin A1c; ABC = hemoglobin A1c, blood pressure, low-density-lipoprotein cholesterol; ACE = angiotensin-converting enzyme; ADA = American Diabetes Association; ARB = angiotensin receptor blocker; BMI = body mass index; BP = blood pressure; CHD = coronary heart disease; CVD = cardiovascular disease; HCHS/SOL = Hispanic Community Health Study/Study of Latinos; LDL-C = low-density-lipoprotein cholesterol; NHANES = National Health and Nutrition Examination Survey; PAD = peripheral artery disease.

Abstract
AIMS To determine the extent to which older vs. younger adults with diabetes intensively control glycemia. METHODS Participants were age≥40years who self-reported a physician diagnosis of diabetes in the 2009-2014 National Health and Nutrition Examination Surveys (N=1554). Intensive glycemic control was defined as A1c<7.0% and taking insulin, sulfonylureas, or ≥2 glycemic medications. Logistic regression was used to determine the adjusted odds of intensive control in older (≥65years) vs. younger adults (age 40-64years). RESULTS The prevalence of intensive control was greater for older (33.4%) vs. younger (21.3%) adults (p<0.001). In logistic regression, intensive control was significantly higher in older vs. younger adults after fully adjusting for sociodemographics, diabetes duration, comorbidities, disability, use of multiple medications, and depression (OR=1.72, 1.09-2.69). The multivariable adjusted prevalence of intensive control was 40% higher in adults ≥75years (35.6%) compared to adults 40-49years (21.7%). CONCLUSIONS Older adults are being treated more aggressively than younger adults to achieve A1c<7.0% despite the presence of comorbidities, duration of diabetes, disability, and depression. Glycemic guidelines for individualized therapy are not being widely followed.

Abstract
BACKGROUND Dietary recommendations for adults with diabetes are to follow a healthy diet in appropriate portion sizes. We determined recent trends in energy and nutrient intakes among a nationally representative sample of US adults with and without type 2 diabetes. METHODS Participants were adults aged ≥20 years from the cross-sectional National Health and Nutrition Examination Surveys, 1988-2012 (N = 49 770). Diabetes was determined by self-report of a physician's diagnosis (n = 4885). Intake of energy and nutrients were determined from a 24-h recall by participants of all food consumed. Linear regression was used to test for trends in mean intake over time for all participants and by demographic characteristics. RESULTS Among adults with diabetes, overall total energy intake increased between 1988-1994 and 2011-2012 (1689 kcal versus 1895 kcal; Ptrend < 0.001) with evidence of a plateau between 2003-2006 and 2011-2012. In 2007-2012, energy intake was greater for younger than older adults, for men than women, and for non-Hispanic whites versus non-Hispanic blacks. There was no change in the percentage of calories from carbohydrate, total fat or protein. Percentage of calories from saturated fat was similar across study periods but remained above recommendations (11.2% in 2011-2012). Fibre intake significantly decreased and remained below recommendations (Ptrend = 0.002). Sodium, cholesterol and calcium intakes increased. There was no change in energy intake among adults without diabetes and dietary trends were similar to those with diabetes. CONCLUSIONS Future data are needed to confirm a plateau in energy intake among adults with diabetes, although the opportunity exists to increase fibre and reduce saturated fat.

Detecting prediabetes among Hispanics/Latinos from diverse heritage groups: Does the test matter? Findings from the Hispanic Community Health Study/Study of Latinos. Prev Med 2017; 95:110-118. [PMID: 27956225 PMCID: PMC5290333 DOI: 10.1016/j.ypmed.2016.12.009] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2016] [Revised: 11/17/2016] [Accepted: 12/07/2016] [Indexed: 12/16/2022]
Abstract
The objectives of this analysis were to compare the ability of fasting plasma glucose (FPG), post oral load plasma glucose (2hPG), and hemoglobin A1c (HbA1c) to identify U.S. Hispanic/Latino individuals with prediabetes, and to assess its cardiovascular risk factor correlates. This is a cross-sectional analysis of baseline data from 15,507 adults without self-reported diabetes mellitus from six Hispanic/Latino heritage groups, enrolled in the Hispanic Community Health Study/Study of Latinos, which takes place in four U.S. communities. The prevalence of prediabetes was determined according to individual or combinations of ADA-defined cut points: FPG=5.6-7.0mmol/L, 2hPG=7.8-11.1mmol/L, and HbA1c=5.7%-6.4% (39-46mmol/mol). The sensitivity of these criteria to detect prediabetes was estimated. The prevalence ratios (PRs) for selected cardiovascular risk factors were compared among alternative categories of prediabetes versus normoglycemia [FPG<5.6mmol/L and 2hPG<7.8mmol/L and HbA1c<5.7% (39mmol/mol)]. Approximately 36% of individuals met any of the ADA prediabetes criteria. Using 2hPG as the gold standard, the sensitivity of FPG was 40.1%, HbA1c was 45.6%, and that of HbA1c+FPG was 62.2%. The number of significant PRs for cardiovascular risk factors was higher among individuals with isolated 2hPG=7.8-11.1mmol/L, FPG=5.6-7.0mmol/L+HbA1c=5.7%-6.4%, or those who met the three prediabetes criteria. Assessing FPG, HbA1c, and cardiovascular risk factors in Hispanics/Latinos at risk might enhance the early prevention of diabetes mellitus and cardiovascular complications in this young and growing population, independent of their heritage group.

Abstract
AIMS Determine the prevalence of glucocorticoid use in U.S. adults with diabetes and whether prevalence is associated with reduced skeletal health, as measured by fracture history and bisphosphonate use. METHODS Participants were age≥20years from the cross-sectional National Health and Nutrition Examination Survey (1999-2010; N=15,661). Diabetes was determined by self-report, fasting plasma glucose ≥126mg/dL (≥6.99mmol/L), or A1c ≥6.5% (≥47.5mmol/mol) (n=4539). Prevalences of fractures and bisphosphonate use were determined by diabetes status and glucocorticoid use. Logistic regression was stratified by sex and assessed the effect of glucocorticoid use and diabetes associated with fractures and bisphosphonates. RESULTS The age-standardized prevalence of glucocorticoid use was higher among persons with diabetes (3.2% vs. 2.0% without diabetes, p=0.001). Among adults with diabetes, the prevalence of fractures was significantly higher among those taking glucocorticoids vs. those not (38.3% vs. 26.1%, p=0.048). The prevalences of fractures and bisphosphonate use were generally similar in those with and without diabetes when stratified by glucocorticoid use. In logistic regression analysis among men, the combination of diabetes and glucocorticoid use (compared to those with neither) was highly associated with bisphosphonate use, while adjusting for demographic factors. Among women, having diabetes and glucocorticoid use increased the odds of fractures, while adjusting for demographic factors and menopause. CONCLUSIONS The prevalence of fractures was greater for those with diabetes taking glucocorticoids versus those not taking glucocorticoids. This study provides a national framework for further research on elucidating these associations.

Abstract
Background The health of younger adults in the U.S. has important public health and economic-related implications. However, previous literature is insufficient to fully understand how the health of this group has changed over time. This study examined generational differences in cardiovascular risk factors of younger adults over the past 40 years. Methods Data were from 6 nationally representative cross-sectional National Health and Nutrition Examination Surveys (1971–2012; N = 44,670). Participants were adults age 20–49 years who self-reported sociodemographic characteristics and health conditions, and had examination/laboratory measures for hypertension, hyperlipidemia, diabetes, obesity, and chronic kidney disease. Prevalences of sociodemographic characteristics and health status were determined by study period. Logistic regression was used to determine the odds [odds ratio (OR), 95% confidence interval] of health conditions by study period: models adjusted only for age, sex, and race, and fully adjusted models additionally adjusted for socioeconomic characteristics, smoking, BMI, diabetes, and/or hypertension (depending on the outcome) were assessed. Results Participants in 2009–2012 were significantly more likely to be obese and have diabetes compared to those in 1971–1975 (OR = 4.98, 3.57–6.97; OR = 3.49, 1.59–7.65, respectively, fully adjusted). Participants in 2009–2012 vs. 1988–1994 were significantly more likely to have had hypertension but uncontrolled hypertension was significantly less likely (OR = 0.67, 0.52–0.86, fully adjusted). There was no difference over time for high cholesterol, but uncontrolled high cholesterol was significantly less likely in 2009–2012 vs. 1988–1994 (OR = 0.80, 0.68–0.94, fully adjusted). The use of hypertensive and cholesterol medications increased while chronic kidney and cardiovascular diseases were relatively stable. Conclusions Cardiovascular risk factors of younger U.S. adults have worsened over the past 40 years, but treatment for hypertension and high cholesterol has improved. The sub-optimal and worsening health in younger adults may have a substantial impact on health care utilization and costs, and should be considered when developing health care practices.

OBJECTIVE The aim of this study was to compare the ability of American Diabetes Association (ADA) diagnostic criteria to identify U.S. Hispanics/Latinos from diverse heritage groups with probable diabetes mellitus and assess cardiovascular risk factor correlates of those criteria. METHODS Cross-sectional analysis of data from 15,507 adults from 6 Hispanic/Latino heritage groups, enrolled in the Hispanic Community Health Study/Study of Latinos. The prevalence of probable diabetes mellitus was estimated using individual or combinations of ADA-defined cut points. The sensitivity and specificity of these criteria at identifying diabetes mellitus from ADA-defined prediabetes and normoglycemia were evaluated. Prevalence ratios of hypertension, abnormal lipids, and elevated urinary albumin-creatinine ratio for unrecognized diabetes mellitus-versus prediabetes and normoglycemia-were calculated. RESULTS Among Hispanics/Latinos (mean age, 43 years) with diabetes mellitus, 39.4% met laboratory test criteria for probable diabetes, and the prevalence varied by heritage group. Using the oral glucose tolerance test as the gold standard, the sensitivity of fasting plasma glucose (FPG) and hemoglobin A1c-alone or in combination-was low (18, 23, and 33%, respectively) at identifying probable diabetes mellitus. Individuals who met any criterion for probable diabetes mellitus had significantly higher (P<.05) prevalence of most cardiovascular risk factors than those with normoglycemia or prediabetes, and this association was not modified by Hispanic/Latino heritage group. CONCLUSION FPG and hemoglobin A1c are not sensitive (but are highly specific) at detecting probable diabetes mellitus among Hispanics/Latinos, independent of heritage group. Assessing cardiovascular risk factors at diagnosis might prompt multitarget interventions and reduce health complications in this young population.

Differences in Hemoglobin A1c Between Hispanics/Latinos and Non-Hispanic Whites: An Analysis of the Hispanic Community Health Study/Study of Latinos and the 2007-2012 National Health and Nutrition Examination Survey. Diabetes Care 2016; 39:1010-7. [PMID: 27208330 PMCID: PMC5317242 DOI: 10.2337/dc15-2579] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2015] [Accepted: 03/25/2016] [Indexed: 02/03/2023]
Abstract
OBJECTIVE To determine whether, after adjustment for glycemia and other selected covariates, hemoglobin A1c (HbA1c) differed among adults from six Hispanic/Latino heritage groups (Central American, Cuban, Dominican, Mexican, Puerto Rican, and South American) and between Hispanic/Latino and non-Hispanic white adults without self-reported diabetes. RESEARCH DESIGN AND METHODS We performed a cross-sectional analysis of data from 13,083 individuals without self-reported diabetes from six Hispanic/Latino heritage groups, enrolled from 2008 to 2011 in the Hispanic Community Health Study/Study of Latinos, and 2,242 non-Hispanic white adults enrolled during the 2007-2012 cycles of the National Health and Nutrition Examination Survey. We compared HbA1c levels among Hispanics/Latinos and between Hispanics/Latinos and non-Hispanic whites before and after adjustment for age, sex, fasting (FPG) and 2-h post-oral glucose tolerance test (2hPG) glucose, anthropometric measurements, and selected biochemical and hematologic variables and after stratification by diabetes status: unrecognized diabetes (FPG ≥7.1 mmol/L or 2hPG ≥11.2 mmol/L), prediabetes (FPG 5.6-7.0 mmol/L or 2hPG 7.8-11.1 mmol/L), and normal glucose tolerance (FPG <5.6 mmol/L and 2hPG <7.8 mmol/L). RESULTS Adjusted mean HbA1c differed significantly across all seven groups (P < 0.001). Non-Hispanic whites had significantly lower HbA1c (P < 0.05) than each individual Hispanic/Latino heritage group. Upon stratification by diabetes status, statistically significant differences (P < 0.001) in adjusted mean HbA1c persisted across all seven groups. CONCLUSIONS HbA1c differs among Hispanics/Latinos of diverse heritage groups and between non-Hispanic whites and Hispanics/Latinos after adjustment for glycemia and other covariates. The clinical significance of these differences is unknown.

Abstract
UNLABELLED Our objective was to evaluate the relationship of urine metals including barium, cadmium, cobalt, cesium, molybdenum, lead, antimony, thallium, tungsten, and uranium with diabetes prevalence. Data were from a cross-sectional study of 9,447 participants of the 1999-2010 National Health and Nutrition Examination Survey, a representative sample of the U.S. civilian noninstitutionalized population. Metals were measured in a spot urine sample, and diabetes status was determined based on a previous diagnosis or an A1C ≥6.5% (48 mmol/mol). After multivariable adjustment, the odds ratios of diabetes associated with the highest quartile of metal, compared with the lowest quartile, were 0.86 (95% CI 0.66-1.12) for barium (Ptrend = 0.13), 0.74 (0.51-1.09) for cadmium (Ptrend = 0.35), 1.21 (0.85-1.72) for cobalt (Ptrend = 0.59), 1.31 (0.90-1.91) for cesium (Ptrend = 0.29), 1.76 (1.24-2.50) for molybdenum (Ptrend = 0.01), 0.79 (0.56-1.13) for lead (Ptrend = 0.10), 1.72 (1.27-2.33) for antimony (Ptrend < 0.01), 0.76 (0.51-1.13) for thallium (Ptrend = 0.13), 2.18 (1.51-3.15) for tungsten (Ptrend < 0.01), and 1.46 (1.09-1.96) for uranium (Ptrend = 0.02). Higher quartiles of barium, molybdenum, and antimony were associated with greater HOMA of insulin resistance after adjustment. Molybdenum, antimony, tungsten, and uranium were positively associated with diabetes, even at the relatively low levels seen in the U.S. POPULATION Prospective studies should further evaluate metals as risk factors for diabetes.

Abstract
BACKGROUND Studies investigating the association between telomere length and diabetes have been inconsistent, and there are few data available investigating the associations of telomere length with diabetes duration and control. We evaluated the relationship of leukocyte telomere length with diabetes, and the relationship of leukocyte telomere length with diabetes duration and poor glucose control among people with diabetes. METHODS We used data from the 1999-2002 National Health and Nutrition Examination Survey, a representative sample of the US civilian non-institutionalized population. In 3921 participants, leukocyte telomere length was measured and diabetes status was determined based on a previous diagnosis, hemoglobin A1c ≥ 6.5 %, or fasting glucose ≥ 126 mg/dL. RESULTS The odds ratios (95 % confidence intervals) of diabetes associated with the first, second, and third quartile of leukocyte telomere length, compared to the highest quartile, was 2.09 (1.46-2.98), 1.74 (1.30-2.31), and 1.08 (0.76-1.54), respectively (p-trend < 0.01), in unadjusted models and 0.74 (0.48-1.14), 0.91 (0.61-1.34), and 0.87 (0.59-1.29), respectively (p-trend = 0.20), in multivariable adjusted models. Among participants with diabetes, unadjusted and adjusted leukocyte telomere length was not associated with diabetes duration or glucose control based on an hemoglobin A1c < 7 or < 8 % (all p > 0.05). CONCLUSIONS In this study of the US general population, leukocyte telomere length was not associated with diabetes status, diabetes duration, or diabetes control.

Abstract
IMPORTANCE Previous studies have shown increasing prevalence of diabetes in the United States. New US data are available to estimate prevalence of and trends in diabetes. OBJECTIVE To estimate the recent prevalence and update US trends in total diabetes, diagnosed diabetes, and undiagnosed diabetes using National Health and Nutrition Examination Survey (NHANES) data. DESIGN, SETTING, AND PARTICIPANTS Cross-sectional surveys conducted between 1988-1994 and 1999-2012 of nationally representative samples of the civilian, noninstitutionalized US population; 2781 adults from 2011-2012 were used to estimate recent prevalence and an additional 23,634 adults from 1988-2010 were used to estimate trends. MAIN OUTCOMES AND MEASURES The prevalence of diabetes was defined using a previous diagnosis of diabetes or, if diabetes was not previously diagnosed, by (1) a hemoglobin A1c level of 6.5% or greater or a fasting plasma glucose (FPG) level of 126 mg/dL or greater (hemoglobin A1c or FPG definition) or (2) additionally including 2-hour plasma glucose (2-hour PG) level of 200 mg/dL or greater (hemoglobin A1c, FPG, or 2-hour PG definition). Prediabetes was defined as a hemoglobin A1c level of 5.7% to 6.4%, an FPG level of 100 mg/dL to 125 mg/dL, or a 2-hour PG level of 140 mg/dL to 199 mg/dL. RESULTS In the overall 2011-2012 population, the unadjusted prevalence (using the hemoglobin A1c, FPG, or 2-hour PG definitions for diabetes and prediabetes) was 14.3% (95% CI, 12.2%-16.8%) for total diabetes, 9.1% (95% CI, 7.8%-10.6%) for diagnosed diabetes, 5.2% (95% CI, 4.0%-6.9%) for undiagnosed diabetes, and 38.0% (95% CI, 34.7%-41.3%) for prediabetes; among those with diabetes, 36.4% (95% CI, 30.5%-42.7%) were undiagnosed. The unadjusted prevalence of total diabetes (using the hemoglobin A1c or FPG definition) was 12.3% (95% CI, 10.8%-14.1%); among those with diabetes, 25.2% (95% CI, 21.1%-29.8%) were undiagnosed. Compared with non-Hispanic white participants (11.3% [95% CI, 9.0%-14.1%]), the age-standardized prevalence of total diabetes (using the hemoglobin A1c, FPG, or 2-hour PG definition) was higher among non-Hispanic black participants (21.8% [95% CI, 17.7%-26.7%]; P < .001), non-Hispanic Asian participants (20.6% [95% CI, 15.0%-27.6%]; P = .007), and Hispanic participants (22.6% [95% CI, 18.4%-27.5%]; P < .001). The age-standardized percentage of cases that were undiagnosed was higher among non-Hispanic Asian participants (50.9% [95% CI, 38.3%-63.4%]; P = .004) and Hispanic participants (49.0% [95% CI, 40.8%-57.2%]; P = .02) than all other racial/ethnic groups. The age-standardized prevalence of total diabetes (using the hemoglobin A1c or FPG definition) increased from 9.8% (95% CI, 8.9%-10.6%) in 1988-1994 to 10.8% (95% CI, 9.5%-12.0%) in 2001-2002 to 12.4% (95% CI, 10.8%-14.2%) in 2011-2012 (P < .001 for trend) and increased significantly in every age group, in both sexes, in every racial/ethnic group, by all education levels, and in all poverty income ratio tertiles. CONCLUSIONS AND RELEVANCE In 2011-2012, the estimated prevalence of diabetes was 12% to 14% among US adults, depending on the criteria used, with a higher prevalence among participants who were non-Hispanic black, non-Hispanic Asian, and Hispanic. Between 1988-1994 and 2011-2012, the prevalence of diabetes increased in the overall population and in all subgroups evaluated.

Receipt of Glucose Testing and Performance of Two US Diabetes Screening Guidelines, 2007-2012. PLoS One 2015; 10:e0125249.

Abstract
BACKGROUND Screening guidelines are used to help identify prediabetes and diabetes before implementing evidence-based prevention and treatment interventions. We examined screening practices benchmarking against two US guidelines, and the capacity of each guideline to identify dysglycemia. METHODS Using 2007-2012 National Health and Nutrition Examination Surveys, we analyzed nationally-representative, cross-sectional data from 5,813 fasting non-pregnant adults aged ≥20 years without self-reported diabetes. We examined proportions of adults eligible for diagnostic glucose testing and those who self-reported receiving testing in the past three years, as recommended by the American Diabetes Association (ADA) and the US Preventive Services Task Force (USPSTF-2008) guidelines. For each screening guideline, we also assessed sensitivity, specificity, and positive (PPV) and negative predictive values in identifying dysglycemia (defined as fasting plasma glucose ≥100 mg/dl or hemoglobin A1c ≥5.7%). RESULTS In 2007-2012, 73.0% and 23.7% of US adults without diagnosed diabetes met ADA and USPSTF-2008 criteria for screening, respectively; and 91.5% had at least one major risk factor for diabetes. Of those ADA- or USPSTF-eligible adults, about 51% reported being tested within the past three years. Eligible individuals not tested were more likely to be lower educated, poorer, uninsured, or have no usual place of care compared to tested eligible adults. Among adults with ≥1 major risk factor, 45.7% reported being tested, and dysglycemia yields (i.e., PPV) ranged from 45.8% (high-risk ethnicity) to 72.6% (self-reported prediabetes). ADA criteria and having any risk factor were more sensitive than the USPSTF-2008 guideline (88.8-97.7% vs. 31.0%) but less specific (13.5-39.7% vs. 82.1%) in recommending glucose testing, resulting in lower PPVs (47.7-54.4% vs. 58.4%). CONCLUSION Diverging recommendations and variable performance of different guidelines may be impeding national diabetes prevention and treatment efforts. Efforts to align screening recommendations may result in earlier identification of adults at high risk for prediabetes and diabetes.

Self-reported prevalence of diabetes screening in the U.S., 2005-2010. Am J Prev Med 2014; 47:780-7. [PMID: 25241199 PMCID: PMC4254011 DOI: 10.1016/j.amepre.2014.07.039] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2013] [Revised: 06/20/2014] [Accepted: 07/21/2014] [Indexed: 12/12/2022]
Abstract
BACKGROUND Early detection of type 2 diabetes has the potential to prevent complications, but the prevalence of opportunistic screening is unknown. PURPOSE To describe the prevalence of diabetes screening by demographic and diabetes-related factors and to determine predictors of screening among a representative U.S. population without self-reported diabetes. METHODS Cross-sectional data were obtained from the 2005-2010 National Health and Nutrition Examination Survey (n=15,125) and 2006 National Health Interview Survey (n=21,519). Participants were aged ≥20 years and self-reported having a diabetes screening test in the past 3 years. Diabetes screening prevalence was analyzed according to risk factors recommended by the American Diabetes Association. Logistic regression was used to determine significant predictors of diabetes screening. Analysis was conducted in 2012-2013. RESULTS The prevalence of having a blood test for diabetes in the past 3 years was 42.1% in 2005-2006, 41.6% in 2007-2008, and 46.8% in 2009-2010. This prevalence increased with age and was higher for women, non-Hispanic whites, and those with more education and income (p<0.001 for all). BMI ≥25, age ≥45 years, having a relative with diabetes, hypertension, glycosylated hemoglobin ≥5.7%, and cardiovascular disease history were significant predictors of screening. For each additional risk factor, the likelihood of screening increased by 51%. CONCLUSIONS Nearly half of the adult population reported having a diabetes screening test. However, testing was less prevalent in minorities and those with lower socioeconomic status. Public health efforts to address these deficiencies in screening are needed.

Abstract
OBJECTIVE Several studies have found a U-shaped association between body mass index (BMI) and mortality in the general population. In similar studies among people with diabetes, the shape of the association is inconsistent. We investigated the relationship of BMI and waist circumference with mortality among people with diabetes. SETTING The Third National Health and Nutrition Examination Survey (NHANES III) and the 1999-2004 NHANES Mortality Studies were designed to be representative of the US general population. Baseline data were collected in 1988-2004. PARTICIPANTS 2607 adults ≥20 years of age with diabetes. PRIMARY OUTCOME MEASURE Participants were followed through 31 December 2006 for mortality (n=668 deaths). RESULTS Compared with people with a BMI 18.5-24.9 kg/m(2), the HRs (95% CI) of mortality were 0.85 (0.60 to 1.21) for 25-29.9 kg/m(2), 0.87 (0.57 to 1.33) for 30-34.9 kg/m(2) and 1.05 (0.72 to 1.53) for ≥35 kg/m(2) after adjustment for age, sex, race-ethnicity, smoking status, education, income and diabetes duration. Compared with people in the lowest sex-specific quartile of waist circumference, the adjusted HRs (95% CI) of mortality were 1.03 (0.77 to 1.37) for the second quartile, 1.02 (0.73 to 1.42) for the third quartile and 1.12 (0.77 to 1.61) for the highest quartile of waist circumference. When modelled as a restricted quadratic spline with knots at the 10th, 50th and 90th centiles, BMI and waist circumference were not associated with mortality. Several sensitivity analyses were conducted and most found no significant association between measures of adiposity and mortality, but there were significant results suggesting a U-shaped association among people in the highest tertile of glycated haemoglobin (≥7.1%), and there was an inverse association between BMI and mortality among people 20-44 years of age. CONCLUSIONS In a nationally representative sample of the non-institutionalised US population with diabetes, BMI and waist circumference were not associated with risk of mortality.

Relationship of hepatitis C virus infection with diabetes in the U.S. population. Hepatology 2014; 60:1139-49.

Abstract
UNLABELLED An association of hepatitis C virus (HCV) infection with diabetes has been reported in many studies, but few have been population based and applied standard criteria for diabetes diagnosis. We examined this relationship using recent population-based data from the U.S. National Health and Nutrition Examination Survey. Adult participants (15,128) in the 1999-2010 surveys had data on diabetes status and serum HCV antibody (anti-HCV) or HCV RNA. Using American Diabetes Association criteria, diabetes was defined as a health care provider diagnosis, serum hemoglobin A1C (A1C) ≥6.5%, or fasting plasma glucose (FPG) ≥126 mg/dL, prediabetes as A1C 5.7%-<6.5% or FPG 100-<126 mg/dL, and normal glucose as A1C <5.7% and FPG <100 mg/dL. Odds ratios (ORs) for diabetes and prediabetes, comparing persons with HCV infection to those without, were adjusted for demographics, BMI, C-reactive protein, smoking, drinking, and blood transfusion before 1992. Among participants without diabetes, we compared mean insulin resistance (IR), estimated using homeostasis model assessment (HOMA-IR), by HCV status. The overall prevalence of anti-HCV+ was 1.7%, of HCV RNA(+) 1.1%, of diabetes 10.5%, and of prediabetes 32.8%. The prevalence of diabetes and prediabetes did not differ by HCV status. In multivariate-adjusted analysis, diabetes remained unassociated with anti-HCV (OR, 1.0; 95% confidence interval [CI]: 0.6-1.7) or with HCV RNA (OR, 1.1; 95% CI: 0.6-1.9). In contrast, elevated alanine aminotransferase and gamma glutamyltransferase activities were associated with diabetes regardless of HCV status. HOMA-IR was not associated with HCV markers in unadjusted or multivariate-adjusted analyses (P > 0.05). CONCLUSION In the U.S. population, HCV was not associated with diabetes or with IR among persons with normal glucose. Previously reported relationships of HCV with diabetes were possibly attributable to the effect of elevated liver enzymes.

Abstract
BACKGROUND The increase in the prevalence of diabetes over the past few decades has coincided with an increase in certain risk factors for diabetes, such as a changing race/ethnicity distribution, an aging population, and a rising obesity prevalence. OBJECTIVE To determine the extent to which the increase in diabetes prevalence is explained by changing distributions of race/ethnicity, age, and obesity prevalence in U.S. adults. DESIGN Cross-sectional, using data from 5 NHANES (National Health and Nutrition Examination Surveys): NHANES II (1976-1980), NHANES III (1988-1994), and the continuous NHANES 1999-2002, 2003-2006, and 2007-2010. SETTING Nationally representative samples of the U.S. noninstitutionalized civilian population. PATIENTS 23 932 participants aged 20 to 74 years. MEASUREMENTS Diabetes was defined as a self-reported diagnosis or fasting plasma glucose level of 7.0 mmol/L (126 mg/dL) or more. RESULTS Between 1976 to 1980 and 2007 to 2010, diabetes prevalence increased from 4.7% to 11.2% in men and from 5.7% to 8.7% in women (P for trends for both groups < 0.001). After adjustment for age, race/ethnicity, and body mass index, diabetes prevalence increased in men (6.2% to 9.6%; P for trend < 0.001) but not women (7.6% to 7.5%; P for trend = 0.69). Body mass index was the greatest contributor among the 3 covariates to the change in prevalence estimates after adjustment. LIMITATION Some possible risk factors, such as physical activity, waist circumference, and mortality, could not be studied because data on these variables were not collected in all surveys. CONCLUSION The increase in the prevalence of diabetes was greater in men than in women in the U.S. population between 1976 to 1980 and 2007 to 2010. After changes in age, race/ethnicity, and body mass index were controlled for, the increase in diabetes prevalence over time was approximately halved in men and diabetes prevalence was no longer increased in women.

Abstract
OBJECTIVE We examine differences in prevalence of diabetes and rates of awareness and control among adults from diverse Hispanic/Latino backgrounds in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). RESEARCH DESIGN AND METHODS The HCHS/SOL, a prospective, multicenter, population-based study, enrolled from four U.S. metropolitan areas from 2008 to 2011 16,415 18-74-year-old people of Hispanic/Latino descent. Diabetes was defined by either fasting plasma glucose, impaired glucose tolerance 2 h after a glucose load, glycosylated hemoglobin (A1C), or documented use of hypoglycemic agents (scanned medications). RESULTS Diabetes prevalence varied from 10.2% in South Americans and 13.4% in Cubans to 17.7% in Central Americans, 18.0% in Dominicans and Puerto Ricans, and 18.3% in Mexicans (P < 0.0001). Prevalence related positively to age (P < 0.0001), BMI (P < 0.0001), and years living in the U.S. (P = 0.0010) but was negatively related to education (P = 0.0005) and household income (P = 0.0043). Rate of diabetes awareness was 58.7%, adequate glycemic control (A1C <7%, 53 mmol/mol) was 48.0%, and having health insurance among those with diabetes was 52.4%. CONCLUSIONS Present findings indicate a high prevalence of diabetes but considerable diversity as a function of Hispanic background. The low rates of diabetes awareness, diabetes control, and health insurance in conjunction with the negative associations between diabetes prevalence and both household income and education among Hispanics/Latinos in the U.S. have important implications for public health policies.

Abstract
OBJECTIVE We examined the impact of intensive versus conventional diabetes treatment upon menopause among women with type 1 diabetes in the Diabetes Control and Complications Trial (DCCT), a randomized controlled trial of intensive diabetes treatment, and its observational follow-up, the Epidemiology of Diabetes Interventions and Complications (EDIC) study. RESEARCH DESIGN AND METHODS In a secondary analysis of women in the DCCT/EDIC (n = 657), outcomes were the cumulative incidences of natural menopause and surgical menopause. Cox regression analyses were used to examine associations with treatment group, time-varying estimates of hemoglobin A1c (HbA1c), insulin dosage, BMI, and microvascular complications (retinopathy, nephropathy, and neuropathy). RESULTS By EDIC year 18, after an average of 28 years of follow-up, 240 (38%) women had experienced natural menopause and 115 (18%) women had experienced surgical menopause. Age at natural menopause was similar in the intensive versus conventional groups (49.9 vs. 49.0 years; P = 0.28), and age at surgical menopause was similar in the intensive versus conventional groups (40.8 vs. 42.0 years; P = 0.31). In multivariable models, treatment group, HbA1c, and microvascular complications were not associated with risk of natural or surgical menopause. Each 10 unit/day increase in insulin dosage decreased risk of natural menopause (hazard ratio [HR] 0.91, 95% CI 0.75-0.98) and each kg/m(2) increase in BMI increased risk of surgical menopause (HR 1.08, 95% CI 1.00-1.16). CONCLUSIONS In the DCCT/EDIC, intensive versus conventional treatment group and HbA1c level were not associated with menopause risk. Greater insulin dose was associated with lower menopause risk.

Hemoglobin A1c, fasting plasma glucose, and 2-hour plasma glucose distributions in U.S. population subgroups: NHANES 2005-2010. Ann Epidemiol 2013; 24:83-9. [PMID: 24246264 DOI: 10.1016/j.annepidem.2013.10.008] [Citation(s) in RCA: 31] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2013] [Revised: 10/01/2013] [Accepted: 10/14/2013] [Indexed: 10/26/2022]
Abstract
PURPOSE Although mean concentrations of hemoglobin A1c (A1C), fasting plasma glucose, and 2-hour plasma glucose differ by demographics, it is unclear what other characteristics of the distributions may differ, such as the amount of asymmetry of the distribution (skewness) and shift left or right compared with another distribution (shift). METHODS Using kernel density estimation, we created smoothed plots of the distributions of fasting plasma glucose (N = 7250), 2-hour plasma glucose (N = 5851), and A1C (N = 16,209) by age, race-ethnicity, and sex in the 2005-2010 National Health and Nutrition Examination Survey, a nationally representative sample of U.S. adults including people with and without diabetes. We tested differences in distributions using cumulative logistic regression. RESULTS The distributions were generally unimodal and right-skewed. All distributions were shifted higher and more right-skewed for older age groups (P < .001 for each marker). Compared with non-Hispanic whites, the distribution of fasting plasma glucose was shifted higher for Mexican-Americans (P = .01), whereas the distribution of A1C was shifted higher for non-Hispanic blacks (P < .001). The distribution of fasting plasma glucose was shifted higher for men (P < .001) and the distribution of 2-hour plasma glucose was shifted higher for women (P = .01). CONCLUSIONS We provide a graphic reference for comparing these distributions and diabetes cut-points by demographic factors.

Secular changes in the age-specific prevalence of diabetes among U.S. adults: 1988-2010. Diabetes Care 2013; 36:2690-6. [PMID: 23637354 PMCID: PMC3747941 DOI: 10.2337/dc12-2074] [Citation(s) in RCA: 133] [Impact Index Per Article: 12.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2012] [Accepted: 03/17/2013] [Indexed: 02/03/2023]
Abstract
OBJECTIVE To examine the age-specific changes of prevalence of diabetes among U.S. adults during the past 2 decades. RESEARCH DESIGN AND METHODS This study included 22,586 adults sampled in three periods of the National Health and Nutrition Examination Survey (1988-1994, 1999-2004, and 2005-2010). Diabetes was defined as having self-reported diagnosed diabetes or having a fasting plasma glucose level ≥ 126 mg/dL or HbA1c ≥ 6.5% (48 mmol/mol). RESULTS The number of adults with diabetes increased by 75% from 1988-1994 to 2005-2010. After adjusting for sex, race/ethnicity, and education level, the prevalence of diabetes increased over the two decades across all age-groups. Younger adults (20-34 years of age) had the lowest absolute increase in diabetes prevalence of 1.0%, followed by middle-aged adults (35-64) at 2.7% and older adults (≥ 65) at 10.0% (all P < 0.001). Comparing 2005-2010 with 1988-1994, the adjusted prevalence ratios (PRs) by age-group were 2.3, 1.3, and 1.5 for younger, middle-aged, and older adults, respectively (all P < 0.05). After additional adjustment for body mass index (BMI), waist-to-height ratio (WHtR), or waist circumference (WC), the adjusted PR remained statistically significant only for adults ≥ 65 years of age. CONCLUSIONS During the past two decades, the prevalence of diabetes increased across all age-groups, but adults ≥ 65 years of age experienced the largest increase in absolute change. Obesity, as measured by BMI, WHtR, or WC, was strongly associated with the increase in diabetes prevalence, especially in adults <65.

Abstract
OBJECTIVE Using a nationally representative sample of the civilian noninstitutionalized U.S. population, we estimated prediabetes prevalence and its changes during 1999-2010. RESEARCH DESIGN AND METHODS Data were from 19,182 nonpregnant individuals aged ≥ 12 years who participated in the 1999-2010 National Health and Nutrition Examination Surveys. We defined prediabetes as hemoglobin A1c (A1C) 5.7 to <6.5% (39 to <48 mmol/mol, A1C5.7) or fasting plasma glucose (FPG) 100 to <126 mg/dL (impaired fasting glucose [IFG]). We estimated the prevalence of prediabetes, A1C5.7, and IFG for 1999-2002, 2003-2006, and 2007-2010. We calculated estimates age-standardized to the 2000 U.S. census population and used logistic regression to compute estimates adjusted for age, sex, race/ethnicity, poverty-to-income ratio, and BMI. Participants with self-reported diabetes, A1C ≥ 6.5% (≥ 48 mmol/mol), or FPG ≥126 mg/dL were included. RESULTS Among those aged ≥ 12 years, age-adjusted prediabetes prevalence increased from 27.4% (95% CI 25.1-29.7) in 1999-2002 to 34.1% (32.5-35.8) in 2007-2010. Among adults aged ≥ 18 years, the prevalence increased from 29.2% (26.8-31.8) to 36.2% (34.5-38.0). As single measures among individuals aged ≥ 12 years, A1C5.7 prevalence increased from 9.5% (8.4-10.8) to 17.8% (16.6-19.0), a relative increase of 87%, whereas IFG remained stable. These prevalence changes were similar among the total population, across subgroups, and after controlling for covariates. CONCLUSIONS During 1999-2010, U.S. prediabetes prevalence increased because of increases in A1C5.7. Continuous monitoring of prediabetes is needed to identify, quantify, and characterize the population of high-risk individuals targeted for ongoing diabetes primary prevention efforts.

Abstract
OBJECTIVE To determine the prevalence of people with diabetes who meet hemoglobin A1c (A1C), blood pressure (BP), and LDL cholesterol (ABC) recommendations and their current statin use, factors associated with goal achievement, and changes in the proportion achieving goals between 1988 and 2010. RESEARCH DESIGN AND METHODS Data were cross-sectional from the National Health and Nutrition Examination Surveys (NHANES) from 1988-1994, 1999-2002, 2003-2006, and 2007-2010. Participants were 4,926 adults aged ≥ 20 years who self-reported a previous diagnosis of diabetes and completed the household interview and physical examination (n = 1,558 for valid LDL levels). Main outcome measures were A1C, BP, and LDL cholesterol, in accordance with the American Diabetes Association recommendations, and current use of statins. RESULTS In 2007-2010, 52.5% of people with diabetes achieved A1C <7.0% (<53 mmol/mol), 51.1% achieved BP <130/80 mmHg, 56.2% achieved LDL <100 mg/dL, and 18.8% achieved all three ABCs. These levels of control were significant improvements from 1988 to 1994 (all P < 0.05). Statin use significantly increased between 1988-1994 (4.2%) and 2007-2010 (51.4%, P < 0.01). Compared with non-Hispanic whites, Mexican Americans were less likely to meet A1C and LDL goals (P < 0.03), and non-Hispanic blacks were less likely to meet BP and LDL goals (P < 0.02). Compared with non-Hispanic blacks, Mexican Americans were less likely to meet A1C goals (P < 0.01). Younger individuals were less likely to meet A1C and LDL goals. CONCLUSIONS Despite significant improvement during the past decade, achieving the ABC goals remains suboptimal among adults with diabetes, particularly in some minority groups. Substantial opportunity exists to further improve diabetes control and, thus, to reduce diabetes-related morbidity and mortality.

Abstract
BACKGROUND Tracking national progress in diabetes care may aid in the evaluation of past efforts and identify residual gaps in care. METHODS We analyzed data for adults with self-reported diabetes from the National Health and Nutrition Examination Survey and the Behavioral Risk Factor Surveillance System to examine risk-factor control, preventive practices, and risk scores for coronary heart disease over the 1999-2010 period. RESULTS From 1999 through 2010, the weighted proportion of survey participants who met recommended goals for diabetes care increased, by 7.9 percentage points (95% confidence interval [CI], 0.8 to 15.0) for glycemic control (glycated hemoglobin level <7.0%), 9.4 percentage points (95% CI, 3.0 to 15.8) for individualized glycemic targets, 11.7 percentage points (95% CI, 5.7 to 17.7) for blood pressure (target, <130/80 mm Hg), and 20.8 percentage points (95% CI, 11.6 to 30.0) for lipid levels (target level of low-density lipoprotein [LDL] cholesterol, <100 mg per deciliter [2.6 mmol per liter]). Tobacco use did not change significantly, but the 10-year probability of coronary heart disease decreased by 2.8 to 3.7 percentage points. However, 33.4 to 48.7% of persons with diabetes still did not meet the targets for glycemic control, blood pressure, or LDL cholesterol level. Only 14.3% met the targets for all three of these measures and for tobacco use. Adherence to the recommendations for annual eye and dental examinations was unchanged, but annual lipid-level measurement and foot examination increased by 5.5 percentage points (95% CI, 1.6 to 9.4) and 6.8 percentage points (95% CI, 4.8 to 8.8), respectively. Annual vaccination for influenza and receipt of pneumococcal vaccination for participants 65 years of age or older rose by 4.5 percentage points (95% CI, 0.8 to 8.2) and 6.9 percentage points (95% CI, 3.4 to 10.4), respectively, and daily glucose monitoring increased by 12.7 percentage points (95% CI, 10.3 to 15.1). CONCLUSIONS Although there were improvements in risk-factor control and adherence to preventive practices from 1999 to 2010, tobacco use remained high, and almost half of U.S. adults with diabetes did not meet the recommended goals for diabetes care.

Abstract
OBJECTIVE To compare health insurance coverage and type of coverage for adults with and without diabetes. RESEARCH DESIGN AND METHODS The data used were from 2,704 adults who self-reported diabetes and 25,008 adults without reported diabetes in the 2009 National Health Interview Survey. Participants reported on their current type of health insurance coverage, demographic information, diabetes-related factors, and comorbidities. If uninsured, participants reported reasons for not having health insurance. RESULTS Among all adults with diabetes, 90% had some form of health insurance coverage, including 85% of people 18-64 years of age and ~100% of people ≥65 years of age; 81% of people without diabetes had some type of coverage (vs. diabetes, P < 0.0001), including 78% of people 18-64 years of age and 99% of people ≥65 years of age. More adults 18-64 years of age with diabetes had Medicare coverage (14% vs. no diabetes, 3%; P < 0.0001); fewer people with diabetes had private insurance (58% vs. no diabetes, 66%; P < 0.0001). People 18-64 years of age with diabetes more often had two health insurance sources compared with people without diabetes (13 vs. 5%, P < 0.0001). The most common private plan was a preferred provider organization (PPO) followed by a health maintenance organization/independent practice organization (HMO/IPA) plan regardless of diabetes status. For participants 18-64 years of age, high health insurance cost was the most common reason for not having coverage. CONCLUSIONS Two million adults <65 years of age with diabetes had no health insurance coverage, which has considerable public health and economic impact. Health care reform should work toward ensuring that people with diabetes have coverage for routine care.

Abstract
OBJECTIVE We examined the prevalence of knowledge of A1C, blood pressure, and LDL cholesterol (ABC) levels and goals among people with diabetes, its variation by patient characteristics, and whether knowledge was associated with achieving levels of ABC control recommended for the general diabetic population. RESEARCH DESIGN AND METHODS Data came from 1,233 adults who self-reported diabetes in the 2005-2008 National Health and Nutrition Examination Survey. Participants reported their last ABC level and goals specified by their physician (not validated by medical record data). Analysis included descriptive statistics and logistic regression. RESULTS Among participants tested in the past year, 48% stated their last A1C level. Overall, 63% stated their last blood pressure level and 22% stated their last LDL cholesterol level. Knowledge of ABC levels was greatest in non-Hispanic whites, lowest in Mexican Americans, and higher with more education and income (all P ≤ 0.02). Demographic associations were similar for those reporting physician-specified ABC goals at the American Diabetes Association-recommended levels (A1C <7%, blood pressure <130/80 mmHg, and LDL cholesterol <100 mg/dL). Nineteen percent of participants stated that their provider did not specify an A1C goal compared with 47% and 41% for blood pressure and LDL cholesterol goals, respectively. For people who self-reported A1C <7.0%, 83% had an actual A1C <7.0%. Otherwise, participant knowledge was not significantly associated with risk factor control, except for in those who knew their last LDL cholesterol level (P = 0.046 for A1C <7.0%). Results from logistic regression corroborated these findings. CONCLUSIONS Ample opportunity exists to improve ABC knowledge. Diabetes education should include behavior change components in addition to information on ABC clinical measures.
