Logistic regression analysis identified fasting insulin, BMI and smoking as risk factors for both cardiovascular endpoints (all p30.0 mg/mmol: both P90 mL/min/1.73m 2. Increased IMT during follow-up was diagnosed in 238 participants (15 %) and 328 (20 %) developed AS. After excluding all participants with incomplete data (n=1327) or already existent cardiovascular impairments (n=366), data sets of 1639 participants were included in the analysis. Results: From n=6825 persons who entered the healthcare program, n=3332 had their first follow-up after 5.0☑.0 years.
For this purpose, fasting insulin and BMI were recoded into dichotomous variables defined as hyperinsulinemia (fasting insulin: >15 μU/ml) or overweight (BMI: ≥25 kg/m²). Adjusted relative risk for increased IMT and AS was calculated by using Mantel-Haenszel analysis. Multivariable logistic regression analyses were performed to determine odds ratios (OR) for the incidence of increased IMT or AS in relation to fasting insulin levels at baseline and its change until follow-up in comparison to basal BMI and its change in comprehensive models (Model 1: baseline laboratory and clinical parameters Model 2: Model 1 + BMI change Model 3: Model 1 + insulin change). Clinical and laboratory parameters were examined. Materials and methods: In an ongoing study, middle-aged (≥40 years) employees of Boehringer Ingelheim were regularly followed up as part of an occupational health care program. We, therefore, hypothesized that increased fasting insulin levels are also associated with precursors of CVD such as increased intima media thickness (IMT > 1 mm) or arteriosclerosis (AS, defined by the occurrence of plaques). KG, Ingelheim upon Rhine, Germany.īackground and aims: Recently published genetic studies could show for the first time a causal link between elevated insulin levels and cardiovascular disease (CVD) risk.
