Abdominal obesity, insulin resistance, and metabolic syndrome in a southern European population.

BACKGROUND: Our objective was to investigate the relationship between abdominal obesity (AO), as measured by waist circumference (WC), insulin resistance (IR), and components of the metabolic syndrome (MS). METHODS: A cross-sectional study was carried out with 283 subjects (130 males and 153 females aged 25-65 years) from a primary care outpatient clinic in Valencia (Spain) over a period of 1 year. Body mass index (BMI), waist circumference (WC), blood pressure (BP), total cholesterol, triglycerides, HDL-C, glucose, and insulin were measured by standard methods. IR was defined as HOMA-IR equal to or greater than 3.8. RESULTS: The prevalence of IR was 39.6%. Subjects were divided into groups according to WC. A 'normal' WC was defined as below 88 cm in women and below 102 cm in men; 'AO' was defined as a WC equal to or above 88 cm in women and equal to or above 102 cm in men. The prevalence of IR was 31.7% in the group with normal WC and 54.6% in the AO group (P<0.001). The percentage of subjects with the MS (high BP, dyslipemia or abnormal glucose tolerance) significantly increased (P<0.001) in subjects with AO (48.4 vs. 18.8% in normal WC subjects). AO is an indicator of IR with an odds ratio of 2.59 (95% CI 1.55-4.29). CONCLUSIONS: AO, expressed as WC, appears to be a good indicator of risk for IR and the MS, particularly in non-obese subjects (BMI<30). The main independent parameters of risk for IR are WC and TG, whereas those for the MS are IR, WC, and age.

[Influence of plasma lipids, APOE genotype and type of LDL receptor gene mutations on myocardial infarction in subjects with familial hypercholesterolemia].

BACKGROUND: Our goal was to analyze the relationship of lipids and lipoproteins, APOE genotype and mutations of the LDL receptor gene with the prevalence of myocardial infarction (MI) in patients with familial hypercholesterolemia (FH) from a Southern European FH population. PATIENTS AND METHOD: We studied 108 heterozygous FH subjects aged > 35 years (41 males). It was a cross-sectional study comparing individuals with FH and MI with individuals with FH without MI. In 88 FH subjects, a mutation of the LDL receptor gene was detected. These FH subjects were divided in carriers of null mutation or no null mutations. We compared lipids and lipoproteins and prevalences of LDL receptor type mutation and APOE genotype. RESULTS: Parameters associated with MI were: age, presence of xanthomas and arcus cornealis, plasma concentrations of total cholesterol (TC), LDLc, TC/HDLc ratio > 5.3 and *4 genotype of the APOE gene. Odds ratio for MI were as follows: presence of xanthomas and arcus cornealis, 1.36 (CI 95%, 1.08-1.71; P = 0.01), age > 54 years (50 th of FH group), 1.56 (CI 95%, 1.19-2.04; P = 0.001) and plasma TC values > 332 mg/dl (50 th of FH group), 1.34 (CI 95%, 1.05-1.71; P = 0.019). In the logistic regression model, only age and TC were significantly associated with MI. CONCLUSIONS: In FH subjects aged over 35 years from a Southern European population, MI is associated with age, plasma TC and LDLc values, TC/HDLc ratio and the *4 genotype. In addition, MI is related with age and TC plasma levels on an independent basis.
