Do European people with type 1 diabetes consume a high atherogenic diet? 7-year follow-up of the EURODIAB Prospective Complications Study.
No full textBACKGROUND/OBJECTIVES:
Individuals with type 1 diabetes have a high risk of developing cardiovascular diseases, and it has been reported that they consume a high atherogenic diet. We examined how nutrient intake and adherence to current European nutritional recommendations evolved in a large cohort of European individuals with type 1 diabetes over a period of 7 years.
SUBJECTS/METHODS:
We analysed data from the EURODIAB Prospective Complications Study, a European multicentre prospective cohort study. Standardized 3-day dietary records were employed in individuals with type 1 diabetes. One thousand one hundred and two patients (553 men, 549 women, baseline age 33 ± 10 years, duration 15 ± 9 years) had complete nutritional data available at baseline and after 7 years. We calculated mean differences in reported nutrients over time and adjusted these for age, gender, HbA1c and BMI with ANOVA models.
RESULTS:
Compared to baseline, there were minor changes in nutrients. Reported protein (-0.35% energy (en), fat (-1.07% en), saturated fat (-0.25% en) and cholesterol (-7.42 mg/1000 kcal) intakes were lower, whereas carbohydrate (+1.23% en) and fibre (+0.46 g/1000 kcal) intakes were higher at the 7-year follow-up. European recommendations for adequate nutrient intakes were followed in individuals with type 1 diabetes for protein (76% at baseline and 78% at follow-up), moderately for fat (34, 40%), carbohydrate (34, 41%) and cholesterol (39, 47%), but poorly for fibre (1.4, 2.4%) and saturated fat (11, 13%).
CONCLUSION:
European individuals with type 1 diabetes consume a high atherogenic diet as few patients met recommendations for dietary fibre and saturated fat. This study showed minor changes in dietary nutrients and energy intakes over a period of 7 years. Nutrition education needs particular focus on strategies to increase dietary fibre and reduce saturated fat to exploit their potential benefit
Severe Hypoglycemia and Cardiovascular Disease Incidence in Type 1 Diabetes: The EURODIAB Prospective Complications Study
No full textOBJECTIVE Frequent episodes of severe hypoglycemia may increase the risk of cardiovascular disease (CVD) in people with diabetes. Our aim was to study the relationship between severe hypoglycemic episodes and CVD incidence in subjects with type 1 diabetes, and further, to assess if markers of inflammation/endothelial injury were enhanced in individuals who experienced hypoglycemic episodes. RESEARCH DESIGN AND METHODS The prospective study included 2,181 type 1 diabetic patients from the EURODIAB Prospective Complications Study. At baseline, frequency of self-reported severe hypoglycemia, defined as episodes serious enough to require the help of another person, was assessed based on responses to a patient questionnaire. Both fatal/nonfatal CVD was assessed 7.3 years after baseline examination. At the follow-up visit, data on both severe and nonsevere hypoglycemic episodes in the previous year were collected through a questionnaire and markers of inflammation/stress response/endothelial injury measured by enzyme-linked immunosorbent assays in the 531 subjects of the nested case-control study, including 363 case subjects with one or more complications of diabetes and 168 control subjects with no evidence of any complication. RESULTS During the follow-up period, 176 patients had incident CVD. Logistic regression analysis showed that severe hypoglycemia at the baseline examination was not associated with incidence of CVD (adjusted odds ratios [95% CI]: one to two episodes, 0.87 [0.55-1.37]; three or more episodes, 1.09 [0.68-1.75]). Furthermore, follow-up serum levels of markers of endothelial damage/inflammation were not cross-sectionally associated with the frequency of hypoglycemic episodes. CONCLUSIONS Taken together our data do not support the hypothesis that in type 1 diabetes, severe hypoglycemia increases the risk of CVD

No full textRelationship between plasma sialic acid and fibrinogen concentration and incident micro- and macrovascular complications in type 1 diabetes. The EURODIAB Prospective Complications Study (PCS)
No full textAims/hypothesis: Type 1 diabetes is associated with an increased risk of vascular complications. This increased risk could be explained by sialic acid and/or fibrinogen. It is also not clear what explains the abolition of sex-related differences affecting risk of CHD in the presence of type 1 diabetes. Therefore, we examined whether fibrinogen and sialic acid are related to incident micro- and macrovascular complications in patients with type 1 diabetes. Methods: A subset (n=2329) of the EURODIAB Prospective Complications Study was analysed. Sialic acid and fibrinogen concentrations were measured at baseline. The main outcomes after 7 years were development of albuminuria, retinopathy, neuropathy and CHD. Results: Univariable and multivariable models using Cox proportional survival analyses showed that an SD unit increase in sialic acid and fibrinogen levels was significantly associated with CHD in men only. Adjusted standardised hazard ratios (sHRs) were 1.50 (95% CI 1.05-2.15) and 1.40 (95% CI 1.06-1.86) for sialic acid and fibrinogen, respectively. Initial associations between (1) sialic acid and incident retinopathy [standardised odds ratio (sOR) men 1.68, 95% CI 1.10-2.57], (2) fibrinogen and retinopathy (sOR women 1.37, 95% CI 1.06-1.78) and (3) sialic acid and neuropathy (sOR men 1.37, 95% CI 1.06-1.77) were shown, but became non-significant in multivariable models. Conclusions/interpretation: Sialic acid and fibrinogen are strong predictors of CHD in men with type 1 diabetes, beyond the effect of established risk factors. The associations found with microvascular complications were not independent of other risk factors
Low peripheral nerve conduction velocities and amplitudes are strongly related to diabetic microvascular complications in type 1 diabetes: the EURODIAB Prospective Complications Study
Get PDFObjective: Slow nerve conduction velocity and reduction in response amplitude are objective hallmarks of diabetic sensorimotor polyneuropathy. As subjective or clinical indicators of neuropathy do not always match well with the presence of abnormal nerve physiology tests, we evaluated associations to nerve conduction in patients with type 1 diabetes. Methods: Nerve conduction studies were performed in the distal sural and ulnar sensory nerves and the peroneal motor nerve in 456 individuals with type 1 diabetes who participated in the follow-up visit of the EURODIAB Prospective Complications Study (EPCS). We used multivariate regression models to describe associations to decreased nerve conduction measures. Results: In addition to an effect of duration of diabetes and HbA1c, which were both associated with low nerve conduction velocity and response amplitude, we found the presence of nephropathy, retinopathy or a clinical diagnosis of neuropathy were associated with low nerve conduction velocity and amplitude. In the case of non-proliferative retinopathy, odds ratio for being in lowest tertile were 2.30 (1.13; 4.67) for nerve conduction velocity. A similar odds ratio was found for each 2% difference in HbA1c (OR: 2.39 (1.68; 3.41). Conclusions: We show that the presence of other microvascular diabetic complications, together with diabetes duration, and HbA1c, are associated to low nerve conduction velocity and amplitude response; and that cardiovascular disease or risk factors do not seem to be associated to these measure
Association of diet and lifestyle with glycated haemoglobin in type 1 diabetes participants in the EURODIAB prospective complications study.
No full textBackground/Objectives:Diet and lifestyle advice for type 1 diabetes (T1DM) patients is based on little evidence and putative effects on glycaemic control. Therefore, we investigated the longitudinal relation between dietary and lifestyle variables and HbA1c levels in patients with type 1 diabetes.Subjects/Methods:A 7-year prospective cohort analysis was performed in 1659 T1DM patients (52% males, mean age 32.5 years) participating in the EURODIAB Prospective Complications Study. Baseline dietary intake was assessed by 3- day records and physical activity, smoking status and alcohol intake by questionnaires. HbA1c during follow-up was centrally assessed by immunoassay. Analysis of variance (ANOVA) and restricted cubic spline regression analyses were performed to assess dose-response associations between diet and lifestyle variables and HbA1c levels, adjusted for age, sex, lifestyle and body composition measures, baseline HbA1c, medication use and severe hypoglycaemic attacks.Results:Mean follow-up of our study population was 6.8 (s.d. 0.6) years. Mean HbA1c level was 8.25% (s.d. 1.85) (or 66.6 mmol/mol) at baseline and 8.27% (s.d. 1.44) at follow-up. Physical activity, smoking status and alcohol intake were not associated with HbA1c at follow-up in multivariable ANOVA models. Baseline intake below the median of vegetable protein
Plasma levels of matrix metalloproteinase-2,-3,-10, and tissue inhibitor of metalloproteinase-1 are associated with vascular complications in patients with type 1 diabetes : the EURODIAB Prospective Complications Study
Get PDFBackground
Impaired regulation of extracellular matrix remodeling by matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinase (TIMP) may contribute to vascular complications in patients with type 1 diabetes. We investigated associations between plasma MMP-1, −2, −3, −9, −10 and TIMP-1, and cardiovascular disease (CVD) or microvascular complications in type 1 diabetic patients. We also evaluated to which extent these associations could be explained by low-grade inflammation (LGI) or endothelial dysfunction (ED).
Methods
493 type 1 diabetes patients (39.5 ± 9.9 years old, 51% men) from the EURODIAB Prospective Complications Study were included. Linear regression analysis was applied to investigate differences in plasma levels of MMP-1, −2, −3, −9, −10, and TIMP-1 between patients with and without CVD, albuminuria or retinopathy. All analyses were adjusted for age, sex, duration of diabetes, Hba1c and additionally for other cardiovascular risk factors including LGI and ED.
Results
Patients with CVD (n = 118) showed significantly higher levels of TIMP-1 [β = 0.32 SD (95%CI: 0.12; 0.52)], but not of MMPs, than patients without CVD (n = 375). Higher plasma levels of MMP-2, MMP-3, MMP-10 and TIMP-1 were associated with higher levels of albuminuria (p-trends were 0.028, 0.004, 0.005 and 0.001, respectively). Severity of retinopathy was significantly associated with higher levels of MMP-2 (p-trend = 0.017). These associations remained significant after further adjustment for markers of LGI and ED.
Conclusions
These data support the hypothesis that impaired regulation of matrix remodeling by actions of MMP-2, -3 and-10 and TIMP-1 contributes to the pathogenesis of vascular complications in type 1 diabetes
Dietary saturated fat and fibre and risk of cardiovascular disease and all-cause mortality among type 1 diabetic patients: the EURODIAB Prospective Complications Study
No full textAIMS/HYPOTHESIS: Low adherence to recommendations for dietary saturated fatty acid (SFA) and fibre intake in patients with type 1 diabetes mellitus may heighten their increased risk of cardiovascular disease (CVD) and mortality. We examined the relationship of SFA and total, soluble and insoluble fibre with incident CVD and all-cause mortality in type 1 diabetic patients.METHODS: A prospective cohort analysis was performed in 2,108 European type 1 diabetic patients aged 15-60 years who were free of CVD at baseline and enrolled in the EURODIAB Prospective Complications Study (51% male). Diet was assessed from a standardised 3 day dietary record. HR were calculated using Cox proportional hazards models.RESULTS: During a mean follow-up of 7.3 years, 148 incident cases of fatal and non-fatal CVD and 46 all-cause deaths were documented. No statistically significant association was found between SFA and CVD and all-cause mortality. Total dietary fibre, per 5 g/day, was associated with lower all-cause mortality risk (HR 0.72; 95% CI 0.55, 0.95). This association was stronger for soluble fibre (per 5 g/day, HR 0.34; 95% CI 0.14, 0.80) compared with insoluble fibre (per 5 g/day; HR 0.66; 95% CI 0.45, 0.97). Similar results were found for the association with CVD.CONCLUSIONS/INTERPRETATION: This study suggests that reported dietary SFA is not significantly associated with CVD and all-cause mortality in type 1 diabetic patients. On the contrary, higher dietary fibre consumption, especially soluble fibre, within the range commonly consumed by type 1 diabetic patients, may contribute to the prevention of CVD and all-cause mortality in type 1 diabetic patients.</p
Glycemic control and all-cause mortality risk in type 1 diabetes patients: the EURODIAB prospective complications study
No full textContext: Glycemic targets and the benefit of intensive glucose control are currently under debate because intensive glycemic control has been suggested to have negative effects on mortality risk in type 2 diabetes patients. Objective: We examined the association between glycated hemoglobin (HbA1c) and all-cause mortality in patients with type 1 diabetes mellitus. Design, Setting, and Patients: A clinic-based prospective cohort study was performed in 2764 European patients with type 1 diabetes aged 15–60 years enrolled in the EURODIAB Prospective Complications Study. Outcome Measure: Possible nonlinearity of the association between HbA1c and all-cause mortality was examined using multivariable restricted cubic spline regression using three (at HbA1c 5.6%, 8.1%, and 11.8%) and five knots (additionally at HbA1c 7.1% and 9.5%). Mortality data were collected approximately 7 years after baseline examination. Results: HbA1c was related to all-cause mortality in a nonlinear manner after adjustment for age and sex. All-cause mortality risk was increased at both low (5.6%) and high (11.8%) HbA1c compared with the reference (median HbA1c: 8.1%) following a U-shaped association [P overall effect = .008 and .04, P nonlinearity = .03 and .11 (three and five knots, respectively)]. Conclusions: Results from our study in type 1 diabetes patients suggest that target HbA1c below a certain threshold may not be appropriate in this population. We recognize that these low HbA1c levels may be related to anemia, renal insufficiency, infection, or other factors not available in our database. If our data are confirmed, the potential mechanisms underlying this increased mortality risk among those with low HbA1c will need further study
