ObjectiveTo examine barriers to health care transition reported by young adults with type 1 diabetes and associations between barriers and prolonged gaps between pediatric and adult diabetes care.MethodsWe surveyed young adults aged 22 to 30 years with type 1 diabetes about their transition experiences, including barriers to timely establishment of adult diabetes care. We evaluated relationships between barriers and gaps in care using multivariate logistic regression.ResultsThe response rate was 53% (258 of 484 eligible subjects). Respondents (62% female) were 26.7 ± 2.4 years old and transitioned to adult diabetes care at 19.5 ± 2.9 years. Reported barriers included lack of specific adult provider referral name (47%) or contact information (27%), competing life priorities (43%), difficulty getting an appointment (41%), feeling upset about leaving pediatrics (24%), and insurance problems (10%). In multivariate analysis, barriers most strongly associated with gaps in care >6 months were lack of adult provider name (odds ratio [OR], 6.1; 95% confidence interval [CI], 3.0-12.7) or contact information (OR, 5.3; 95% CI, 2.0-13.9), competing life priorities (OR, 5.2; 95% CI, 2.7-10.3), and insurance problems (OR, 3.5; 95% CI, 1.2-10.3). Overall, respondents reporting ≥1 moderate/major barrier (48%) had 4.7-fold greater adjusted odds of a gap in care >6 months (95% CI, 2.8-8.7).ConclusionSignificant barriers to transition, such as a lack of specific adult provider referrals, may be addressed with more robust preparation by pediatric providers and care coordination. Further study is needed to evaluate strategies to improve young adult self-care in the setting of competing life priorities. (Endocr Pract. 2013;19:946-952) 相似文献

Background
This study analyzed the prevalence of and association between symptoms of eating disorders and depression in female and male emerging adults with early-onset, long-duration type 1 diabetes and investigated how these symptoms are associated with metabolic control.Methods
In a nationwide population-based survey, 211 type 1 diabetes patients aged 18-21 years completed standardized questionnaires, including the SCOFF questionnaire for eating disorder symptoms and the Patient Health Questionnaire (PHQ-9) for symptoms of depression and severity of depressive symptoms (PHQ-9 score). Multiple linear and logistic regression models were used to analyze the association between eating disorder and depressive symptoms and their associations with HbA1c.Results
A total of 30.2% of the women and 9.5% of the men were screening positive for eating disorders. The mean PHQ-9 score (standard deviation) was 5.3 (4.4) among women and 3.9 (3.6) among men. Screening positive for an eating disorder was associated with more severe depressive symptoms among women (βwomen 3.8, p<0.001). However, neither eating disorder symptoms nor severity of depressive symptoms were associated with HbA1c among women, while HbA1c increased with the severity of depressive symptoms among men (βmen 0.14, p=0.006).Conclusions
Because of the high prevalence of eating disorder and depressive symptoms, their interrelationship, and their associations with metabolic control, particularly among men, regular mental health screening is recommended for young adults with type 1 diabetes. 相似文献3.

Differences in the effectiveness of diverse healthcare providers to promote health behavior change and successful diabetes self-care have received little attention. Because training in naturopathic medicine (NM) emphasizes a patient-centered approach, health promotion, and routine use of clinical counseling on wellness and prevention, naturopathic physicians (NDs) may be particularly well-prepared for promoting behavior change. However, patients’ experiences with NM have not been well studied. This study provides the first report of the perceptions of persons with type 2 diabetes of their first experiences with naturopathic care for their diabetes. Following their participation in a one-year prospective cohort study of adjunctive naturopathic care for diabetes, twenty-two patients were interviewed about their experiences working with a naturopathic physician. Using a content analysis approach, nine dominant themes were identified. Three themes characterized the nature of the ND-patient interaction: 1) patient-centered, 2) holistic health rather than diabetes focused, and 3) collaborative. Five themes characterized the content of the clinical encounter: 1) individualized and detailed health promotion, 2) counseling that promoted self-efficacy, 3) pragmatic and practical self-care recommendations, 4) novel treatment options that fostered hopefulness, and 5) patient education that addressed both diabetes self-care and general health. A ninth theme was cross-cutting: the contrast between ND care and conventional medical care. Results indicate that the routine clinical approach used by NDs is consistent with behavior change theory and clinical strategies found most effective in promoting self-efficacy and improving clinical outcomes. 相似文献

Background
Recent evidence suggests that there is a link between metabolic diseases and bacterial populations in the gut. The aim of this study was to assess the differences between the composition of the intestinal microbiota in humans with type 2 diabetes and non-diabetic persons as control.Methods and Findings
The study included 36 male adults with a broad range of age and body-mass indices (BMIs), among which 18 subjects were diagnosed with diabetes type 2. The fecal bacterial composition was investigated by real-time quantitative PCR (qPCR) and in a subgroup of subjects (N = 20) by tag-encoded amplicon pyrosequencing of the V4 region of the 16S rRNA gene. The proportions of phylum Firmicutes and class Clostridia were significantly reduced in the diabetic group compared to the control group (P = 0.03). Furthermore, the ratios of Bacteroidetes to Firmicutes as well as the ratios of Bacteroides-Prevotella group to C. coccoides-E. rectale group correlated positively and significantly with plasma glucose concentration (P = 0.04) but not with BMIs. Similarly, class Betaproteobacteria was highly enriched in diabetic compared to non-diabetic persons (P = 0.02) and positively correlated with plasma glucose (P = 0.04).Conclusions
The results of this study indicate that type 2 diabetes in humans is associated with compositional changes in intestinal microbiota. The level of glucose tolerance should be considered when linking microbiota with metabolic diseases such as obesity and developing strategies to control metabolic diseases by modifying the gut microbiota. 相似文献5.

Objective: Screening for depression, diabetes distress, and disordered eating in youth with type 1 diabetes (T1D) is recommended, as these comorbidities contribute to poor glycemic control. No consensus exists on which measures are optimal, and most previous studies have used nondisease-specific measures. We examined the utility of screening for these disorders using two disease-specific and one general measure at the time of transition from pediatric to adult care.Methods: Forty-three young adults from a T1D transition clinic completed the Patient Health Questionnaire, the Diabetes Distress Scale, and the Diabetes Eating Problem Survey–Revised. Chart review determined if clinicians noted similar symptoms during the year prior to transition. Metabolic data were also recorded.Results: Chart review identified 5 patients with depressive symptoms and 8 patients with diabetes distress. Screening identified 2 additional patients with depressive symptoms and 1 additional patient with diabetes distress. Of those noted to have symptomatic depression or diabetes distress on chart review, several subsequently screened negative on transition. Disordered eating was not detected by chart review, but 23.5% screened positive on transition. While depression, diabetes distress, and disordered eating positively correlated with glycated hemoglobin (HbA1c) (r = 0.31, P = .05; r = 0.40, P = .009; r = 0.63, P<.001, respectively), disordered eating accounted for the majority of observed variance (df = 1; F = 18.6; P<.001). Even though HbA1c was higher in patients with versus without disordered eating (P<.001), body mass index did not differ between the 2 groups (P = .51).Conclusion: In young adults with T1D, formal screening provides an opportunity to detect psychological problems, which, when treated, may help optimize metabolic control during the transition process.Abbreviations:T1D = type 1 diabetesHbA1C = hemoglobin A1cYCDP = Yale Children's Diabetes ProgramPHQ-8 = Patient Health Questionnaire–8DDS = Diabetes Distress ScaleDEPS-R = Diabetes Eating Problem Survey–Revised 相似文献

Introduction
There is evidence that greater neighbourhood walkability (i.e., neighbourhoods with more amenities and well-connected streets) is associated with higher levels of total walking in Europe and in Asia, but it remains unclear if this association holds in the Canadian context and in chronic disease populations. We examined the relationships of different walkability measures to biosensor-assessed total walking (i.e., steps/day) in adults with type 2 diabetes living in Montreal (QC, Canada).Materials and Methods
Participants (60.5±10.4 years; 48.1% women) were recruited through McGill University-affiliated clinics (June 2006 to May 2008). Steps/day were assessed once per season for one year with pedometers. Neighbourhood walkability was evaluated through participant reports, in-field audits, Geographic Information Systems (GIS)-derived measures, and the Walk Score®. Relationships between walkability and daily steps were estimated using Bayesian longitudinal hierarchical linear regression models (n = 131).Results
Participants who reported living in the most compared to the least walkable neighbourhoods completed 1345 more steps/day (95% Credible Interval: 718, 1976; Quartiles 4 versus 1). Those living in the most compared to the least walkable neighbourhoods (based on GIS-derived walkability) completed 606 more steps per day (95% CrI: 8, 1203). No statistically significant associations with steps were observed for audit-assessed walkability or the Walk Score®.Conclusions
Adults with type 2 diabetes who perceived their neighbourhoods as more walkable accumulated more daily steps. This suggests that knowledge of local neighborhood features that enhance walking is a meaningful predictor of higher levels of walking and an important component of neighbourhood walkability. 相似文献8.

Background: The cytotoxic T lymphocyteassociated
antigen 4 gene (CTLA-4) encode the
T cell receptor involved in the control of T cell
proliferation and mediates T cell apoptosis.
The receptor protein is a specific T lymphocyte
surface antigen that is detected on cells only
after antigen presentation. Thus, CTLA-4 is
directly involved in both immune and autoimmune
responses and may be involved in the
pathogenesis of multiple T cell-mediated
autoimmune disorders. There is polymorphism
at position 49 in exon 1 of the CTLA-4 gene,
providing an A-G exchange. Moreover, we
assessed the CTLA-4 49 (Thr/Ala) polymorphism
in diabetic patients and first-degree relatives
as compared to control subjects.
Research design and methods: Three loci
(HLA-DQB1, DQA1 and CTLA-4) were analysed in 62 type 1 diabetic patients, 72 firstdegree
relatives and 84 nondiabetic control
subjects by means of PCR-RFLP.
Results: A significant enrichment in DQB1
alleles encoding for an amino acid different
from Asp in position 57 (NA) and DQA1 alleles
encoding for Arg in position 52 was
observed in diabetic subjects and first-degree
relatives as compared to controls. The genotype
and allele frequencies of these polymorphisms
in type 1 diabetic patients and firstdegree
relatives differed significantly from
those of controls (p< 0.001 and 0.05 respectively).
CTLA-49 Ala alleles frequencies were
75.8% in type 1 diabetic patients and 68.1% in
first-degree relatives in comparison to 35.7% in
control subjects. The Ala/Ala genotype conferred
a relative risk of 18.8 (p < 0.001).
Conclusion: The CTLA-4 49 Ala allele confers
an increased risk of type 1 diabetes, independent
of age and HLA-DQ genetic markers. 相似文献

Background
Current guidelines for the management of type 2 diabetes and gout recommend that people with these conditions limit their sugar sweetened beverage (SSB) intake. We examined self-reported SSB intake among New Zealand adults with gout or type 2 diabetes, including those on hemodialysis.Method
1023 adults with gout and 580 adults (including 206 receiving hemodialysis) with type 2 diabetes, participated in this study of between 2009 and 2012. Participants completed an interviewer-administered SSB intake question “how many sugar sweetened drinks (including fruit juice), but not including diet drinks, do you normally drink per day?” SSB consumption was recorded as a circled number 0, 1, 2, 3, 4, 5, or >5, cans or large glasses (300mL) per day.Results
Consuming one or more SSB per day was reported by 64% (622/1023) of subjects with gout, 49% (176/374) with type 2 diabetes without dialysis, and 47% (96/206) with diabetes on dialysis. Consuming four or more SSBs per day was reported by 18% (179/1023), 9% (31/374) and 9% (18/206), respectively. Such high consumers of SSB were characterized after multivariable analysis to be more likely to be male (adjusted odds ratio (OR) 1.8; 95% confidence interval 1.1–2.9), younger in age (40 vs 65 years: 1.6; 1.1–2.3), current smoker (5.2; 2.7–10.1), obese (BMI 41 vs 26kg/m2: 1.4; 1–1.9), and report Māori (1.8; 1.2–2.8) or Pacific (1.6; 1.1–2.5) ancestry, compared to Caucasian. People with gout were more likely to report heavy SSB intake compared to people with diabetes (OR 2.4, 95% CI 1.5–3.9). Heavy SSB consumption reported by people with diabetes was similar if they did or did not require dialysis.Conclusion
A high proportion of patients with gout and type 2 diabetes, including those on haemodialysis, are not responding to health messages to abstain from SSB consumption. 相似文献10.

Background
Randomized controlled trials have shown the importance of tight glucose control in type 1 diabetes (T1DM), but few recent studies have evaluated the risk of cardiovascular disease (CVD) and all-cause mortality among adults with T1DM. We evaluated these risks in adults with T1DM compared with the non-diabetic population in a nationwide study from Scotland and examined control of CVD risk factors in those with T1DM.Methods and Findings
The Scottish Care Information-Diabetes Collaboration database was used to identify all people registered with T1DM and aged ≥20 years in 2005–2007 and to provide risk factor data. Major CVD events and deaths were obtained from the national hospital admissions database and death register. The age-adjusted incidence rate ratio (IRR) for CVD and mortality in T1DM (n = 21,789) versus the non-diabetic population (3.96 million) was estimated using Poisson regression. The age-adjusted IRR for first CVD event associated with T1DM versus the non-diabetic population was higher in women (3.0: 95% CI 2.4–3.8, p<0.001) than men (2.3: 2.0–2.7, p<0.001) while the IRR for all-cause mortality associated with T1DM was comparable at 2.6 (2.2–3.0, p<0.001) in men and 2.7 (2.2–3.4, p<0.001) in women. Between 2005–2007, among individuals with T1DM, 34 of 123 deaths among 10,173 who were <40 years and 37 of 907 deaths among 12,739 who were ≥40 years had an underlying cause of death of coma or diabetic ketoacidosis. Among individuals 60–69 years, approximately three extra deaths per 100 per year occurred among men with T1DM (28.51/1,000 person years at risk), and two per 100 per year for women (17.99/1,000 person years at risk). 28% of those with T1DM were current smokers, 13% achieved target HbA1c of <7% and 37% had very poor (≥9%) glycaemic control. Among those aged ≥40, 37% had blood pressures above even conservative targets (≥140/90 mmHg) and 39% of those ≥40 years were not on a statin. Although many of these risk factors were comparable to those previously reported in other developed countries, CVD and mortality rates may not be generalizable to other countries. Limitations included lack of information on the specific insulin therapy used.Conclusions
Although the relative risks for CVD and total mortality associated with T1DM in this population have declined relative to earlier studies, T1DM continues to be associated with higher CVD and death rates than the non-diabetic population. Risk factor management should be improved to further reduce risk but better treatment approaches for achieving good glycaemic control are badly needed.

Objective: Review available data on adjunctive therapies for type 1 diabetes (T1D), with a special focus on newer antihyperglycemic agents.Methods: Published data on hypoglycemia, obesity, mortality, and goal attainment in T1D were reviewed to determine unmet therapeutic needs. PubMed databases and abstracts from recent diabetes meetings were searched using the term “type 1 diabetes” and the available and investigational sodium-glucose cotransporter (SGLT) inhibitors, glucagon-like peptide 1 (GLP-1) receptor agonists, dipeptidyl peptidase 4 inhibitors, and metformin.Results: The majority of patients with T1D do not meet glycated hemoglobin (A1C) goals established by major diabetes organizations. Hypoglycemia risks and a rising incidence of obesity and metabolic syndrome featured in the T1D population limit optimal use of intensive insulin therapy. Noninsulin antihyperglycemic agents may enable T1D patients to achieve target A1C levels using lower insulin doses, which may reduce the risk of hypoglycemia. In pilot studies, the SGLT2 inhibitor dapagliflozin and the GLP-1 receptor agonist liraglutide reduced blood glucose, weight, and insulin dose in patients with T1D. Phase 2 studies with the SGLT2 inhibitor empagliflozin and the dual SGLT1 and SGLT2 inhibitor sotagliflozin, which acts in the gut and the kidney, have demonstrated reductions in A1C, weight, and glucose variability without an increased incidence of hypoglycemia.Conclusion: Newer antihyperglycemic agents, particularly GLP-1 agonists, SGLT2 inhibitors, and dual SGLT1 and SGLT2 inhibitors, show promise as adjunctive treatment for T1D that may help patients achieve better glucose control without weight gain or increased hypoglycemia.Abbreviations:A1C = glycated hemoglobinBMI = body mass indexCI = confidence intervalDKA = diabetic ketoacidosisDPP-4 = dipeptidyl peptidase 4GLP-1 = glucagonlike peptide 1PYY = polypeptide tyrosine tyrosineSGLT = sodium-glucose cotransporterSGLT1 = sodium-glucose cotransporter 1SGLT2 = sodium-glucose cotransporter 2T1D = type 1 diabetesT2D = type 2 diabetesTDD = total daily dosage 相似文献

ObjectivesType 1 diabetes (T1D) is a chronic disease with patients across the age spectrum that has high potential for morbidity and mortality. Unfortunately, patients transitioning from pediatric to adult care continue to demonstrate worsened glycemic control in part due to lack of understanding of transition of care best practices.MethodsThis review highlights the impact of existing transition of care interventions, assessment tools, and other recently published strategies for providers to consider to improve care of adolescent and young adult (AYA) patients with T1D in both hospital- and clinic-based settings.ResultsMany barriers impact patients with T1D during the transition period and disparities by race, sex, insurance status, and comorbid illness persist. As diabetic care continues to evolve and the prevalence of adolescents and young adults living with T1D increases, an intentional approach to transition of care is more pressing than ever. While current literature on transition of care models is limited, many show promise in improving clinic attendance and decreasing hospitalization. There are critical discussions that providers should lead with AYA patients to improve their outcomes and increase diabetes self-management, such as re-addressing carbohydrate counseling, sleep hygiene, and reproductive planning.ConclusionWhile further research on transition of care is needed, many care models offer the promise of improved T1D outcomes, enhancements in our approach to care, and increased value for our health care system at large. 相似文献

Context
Limited population-based study focused on relationship between eosinophil and type 2 diabetes (T2D).Objectives
We aimed to evaluate the relationship between peripheral eosinophil percentage and glucose metabolism and insulin resistance in a large sample size of Chinese population aged 40 and older.Design and Methods
A cross-sectional study was performed among 9,111 Chinese adults including 3,561 men and 5,550 women. The glucose metabolism status was confirmed by 75-g oral glucose tolerance test. Homeostasis model assessment of insulin resistance index and serum insulin levels were used to evaluate insulin resistance. Homeostasis model assessment-B was used to evaluate β cell function.Results
The average age of participants was 58.5 years. The prevalence of T2D decreased across the tertiles of eosinophil percentage (21.3%, 18.2% and 16.9%, P<0.0001). Each one tertile increase of eosinophil percentage inversely associated with risk of T2D when referred not only to normal glucose tolerance (NGT) (odds ratio (OR) 0.81, 95% CI 0.76–0.87, P< 0.0001), but also to impaired glucose regulation (OR 0.89, 95% CI 0.83–0.97, P = 0.006), respectively, after adjustment for the confounding factors. Compared with the first tertile, the third tertile of eosinophil percentage associated with a 23% decrease of insulin resistance in NGT participants after full adjustments (P = 0.005). Each 1-standard deviation of increment of eosinophil percentage associated with a 37% decrease of insulin resistance (P = 0.005).Conclusions
Higher peripheral eosinophil percentage was associated with decreased risk of T2D. The inverse relation to insulin resistance was detected in NGT participants. 相似文献15.

ObjectiveTo assess the prevalence of sleep apnea (SA) in adults with type 2 diabetes mellitus (T2DM) and examine whether demographics and comorbid factors were associated with SA in this population.MethodsThis study enrolled 330 consecutive adults with T2DM referred to a diabetes clinic, 279 of whom completed the study. Evaluation of the presence of SA was performed with use of a single-channel recording device that measures disordered breathing events from a nasal cannula airflow signal. The device was worn by the study participants in their home, after instruction in appropriate use by clinical staff at the diabetes center. The presence and severity of SA were determined by use of an apnea-hypopnea index (AHI), reflecting periods of diminished and absent breathing. Demographic and medical information data were collected to detect factors associated with SA in this study population. In addition, a time and cost analysis was conducted regarding the screening process for SA by clinical staff at the diabetes center.ResultsThe results show a high prevalence of SA in adults with T2DM, ranging from 48% (AHI level of ≥ 10 events/h) to 29% (AHI level of ≥ 20 events/h). At an AHI cutoff value of ≥ 15 events/h, the overall prevalence rate was 36% (49% in male and 21% in female participants). The following variables were associated with SA: age ≥ 62 years, male sex, body mass index ≥ 30 kg/m2, snoring, and reports of stopping breathing during sleep. The time and cost analysis showed that the screening device involved minimal setup time, was simple to use, and was a cost-effective method to screen for SA.ConclusionSA is a common disorder associated with major morbid conditions, including hypertension, obesity, cardiovascular disease, and insulin resistance. Predisposing factors for SA and T2DM are similar. This study showed that SA has a high prevalence in adults with T2DM and identified factors that may be associated with its presence in this population. Assessment for SA can be easily performed in an outpatient setting with a portable recording device such as the one used in this study. Screening for SA should be considered in the T2DM population.

Background
The individual contribution of genes in the HLA region to the risk of developing type 1 diabetes (T1D) is confounded by the high linkage disequilibrium (LD) in this region. Using a novel approach we have combined genetic association data with information on functional protein-protein interactions to elucidate risk independent of LD and to place the genetic association into a functional context.Methodology/Principal Findings
Genetic association data from 2300 single nucleotide polymorphisms (SNPs) in the HLA region was analysed in 2200 T1D family trios divided into six risk groups based on HLA-DRB1 genotypes. The best SNP signal in each gene was mapped to proteins in a human protein interaction network and their significance of clustering in functional network modules was evaluated. The significant network modules identified through this approach differed between the six HLA risk groups, which could be divided into two groups based on carrying the DRB1*0301 or the DRB1*0401 allele. Proteins identified in networks specific for DRB1*0301 carriers were involved in stress response and inflammation whereas in DRB1*0401 carriers the proteins were involved in antigen processing and presentation.Conclusions/Significance
In this study we were able to hypothesise functional differences between individuals with T1D carrying specific DRB1 alleles. The results point at candidate proteins involved in distinct cellular processes that could not only help the understanding of the pathogenesis of T1D, but also the distinction between individuals at different genetic risk for developing T1D. 相似文献17.

Type 2 diabetes mellitus (T2DM) brings about an increasing psychosocial problem in adult patients. Prevalence data on and associated factors of diabetes related distress (DRD) and depression have been lacking in Asia. This study aimed to examine the prevalence of DRD and depression, and their associated factors in Asian adult T2DM patients. This study was conducted in three public health clinics measuring DRD (Diabetes Distress Scale, DDS), and depression (Patient Health Questionnaire, PHQ). Patients who were at least 30 years of age, had T2DM for more than one year, with regular follow-up and recent laboratory results (< 3 months) were consecutively recruited. Associations between DRD, depression and the combination DRD-depression with demographic and clinical characteristics were analysed using generalized linear models. From 752 invited people, 700 participated (mean age 56.9 years, 52.8% female, 52.9% Malay, 79.1% married). Prevalence of DRD and depression were 49.2% and 41.7%, respectively. Distress and depression were correlated, spearman’s r = 0.50. Patients with higher DRD were younger (OR 0.995, 95% CI 0.996 to 0.991), Chinese (OR 1.2, 95% CI 1.04 to 1.29), attending Dengkil health clinic (OR 1.1, 95% CI 1.00 to 1.22) and had higher scores on the PHQ (OR 1.1, 95% CI 1.04 to 1.06). Depression was less likely in the unmarried compared to divorced/separately living and those attending Dengkil health clinic, but more likely in patients with microvascular complications (OR 1.4, 95% CI 1.06 to 1.73) and higher DDS (OR 1.03, 95% CI 1.02 to 1.03). For the combination of DRD and depression, unemployment (OR 4.7, 95% CI 1.02 to 21.20) had positive association, whereas those under medical care at the Salak health clinics (OR 0.28, 95% CI 0.12 to 0.63), and those with a blood pressure > 130/80 mmHg (OR 0.53, 95% CI 0.32 to 0.89) were less likely to experience both DRD and depression. DRD and depression were common and correlated in Asian adults with T2DM at primary care level. Socio-demographic more than clinical characteristics were related to DRD and depression. 相似文献
