Ten-year (2002–2012) cardiovascular disease incidence and all-cause mortality, in urban Greek population: The ATTICA Study

AIM The 10-year incidence of cardiovascular disease (CVD) and all-cause mortality, as well as its determinants, in a sample of men and women from Greece, was evaluated. METHODS From May 2001 to December 2002, 1514 men and 1528 women (>18y) without any clinical evidence of CVD or any other chronic disease, at baseline, living in greater Athens area, in Greece, were enrolled. In 2011-12, the 10-year follow-up was performed in 2583 participants (15% of the participants were lost to follow-up). Incidence of fatal or non-fatal CVD (coronary heart disease, acute coronary syndromes, stroke, or other CVD) was defined according to World Health Organization (WHO)-International Coding Diseases (ICD)-10 criteria. RESULTS The 10-year CVD incidence was 19.7% in men and 11.7% in women (p<0.001). Multi-adjusted analysis revealed that the determinants of CVD events were increased age (Hazard ratio (HR) per year=1.06, 95%Confidence Interval (CI): 1.04, 1.08), male sex (HR=1.40, 95%CI: 0.90, 2.19), smoking (HR=1.53, 95%CI: 1.03, 2.27), C-reactive protein levels (HR per 1mg/L=1.06, 95%CI: 1.02, 1.15), as well as adherence to Mediterranean diet (protective) (HR per 1/55 units=0.98, 95%CI: 0.95, 1.01). CONCLUSION The burden of CVD and its related risk factors is at emerging rates, in Greece, making the need for effective public health actions, more necessary than ever before.

Effects of alcohol consumption and the metabolic syndrome on 10-year incidence of diabetes: the ATTICA study.

AIM The purpose of this prospective study was to investigate the effect of alcohol consumption on the 10-year diabetes incidence. METHODS In 2001-2002, a random sample of 1514 men (18-89 years old) and 1528 women (18-87 years old) was selected to participate in the ATTICA study (Athens metropolitan area, Greece). Among various other characteristics, average daily alcohol intakes (abstention, low, moderate, high) and type of alcoholic drink were evaluated. Diabetes was defined according to American Diabetes Association criteria. During 2011-2012, the 10-year follow-up was performed. RESULTS The 10-year incidence of diabetes was 13.4% in men and 12.4% in women. After making various adjustments, those who consumed up to 1 glass/day of alcohol had a 53% lower diabetes risk (RR=0.47; 95% CI: 0.26, 0.83) compared with abstainers, while trend analysis revealed a significant U-shaped relationship between quantity of alcohol drunk and diabetes incidence (P<0.001 for trend). Specific types of drinks were not associated with diabetes incidence; however, a one-unit increase in ratio of wine/beer/vodka vs. other spirits was associated with an 89% lower risk of diabetes (RR=0.11; 95% CI: 0.02, 0.67). The protective effect of low alcohol consumption on diabetes incidence was more prominent among individuals with stricter adherence to the Mediterranean diet (RR=0.08; 95% CI: 0.011, 0.70) and without the metabolic syndrome (RR=0.34; 95% CI: 0.16, 0.70). CONCLUSION This work revealed the protective effect of modest alcohol consumption of particularly wine and beer against the long-term incidence of diabetes, possibly due to their pleiotropic health effects.

10-year incidence of diabetes and associated risk factors in Greece: the ATTICA study (2002-2012).

BACKGROUND The incidence of diabetes in the general population is increasing world-wide. The increase is attributed to the consumption of saturated fatty acids, obesity, lack of physical activity, genetic predisposition, and other factors, but knowledge about the reasons, biological mechanisms, and late complications is insufficient. It is therefore important to clarify the reasons more exactly through long-term clinical trials to stop the rise of diabetes and its complications. AIM To evaluate the 10-year incidence of type 2 diabetes in apparently healthy Greek adults. METHODS In 2001-2002, a random sample of 1514 men (18-87 years old) and 1528 women (18-89 years old) was selected to participate in the ATTICA study. During 2011-2012, the 10-year follow-up was performed. Patients diagnosed with diabetes at baseline (n = 210) and those lost at the 10-year follow-up (n = 1347) were excluded, yielding a final sample of 1485 participants. RESULTS During the period of investigation, diabetes was diagnosed in 191 cases corresponding to a 12.9% incidence (95%CI: 10.4-15.4), with 13.4% (95%CI: 10.8-16) in men and 12.4% (95%CI: 10.1-14.7) in women. A relative increase was observed in the second half of the 10-year follow-up when age became significant. Multiple logistic regression analysis revealed that age (OR = 1.14, 95%CI: 1.09-1.19), abnormal waist-to-height ratio (OR = 3.27, 95%CI: 1.07-10.0), fasting blood glucose (OR per 1 mg/dl = 0.05, 95%CI: 1.02-1.08), energy intake (OR per 500 kcal = 1.02, 95%CI: 1.01-1.35), and family history of diabetes (OR = 2.8, 95%CI: 1.30-6.03) were the most significant baseline predictors for diabetes, after adjusting for potential confounders. Waist-to-height ratio showed the best explanatory power of all anthropometric variables. Physical activity exerts an effect on risk factors. Being active was found to eliminate the aggravating effect of diabetes family history and fasting blood glucose. CONCLUSIONS The findings confirm the escalating increase of type 2 diabetes incidence in Greece, which is in line with global trends. A lifestyle change in individuals at risk of developing diabetes towards healthier eating and increased physical activity would be an effective and inexpensive means of reducing diabetes.

Arterial aging mediates the effect of TNF-α and ACE polymorphisms on mental health in elderly individuals: insights from IKARIA study

Background Aging is characterized by an insidious decline in cognitive function. Several genetic and lifestyle factors have been implicated in the increased risk or early onset of dementia. Aim We sought to assess the role of tumor necrosis factor (TNF) and angiotensin-converting enzyme (ACE) polymorphisms on the development of impaired mental health in respect to indices of arterial aging in nonagenarian individuals. Design 178 consecutive subjects above 75 years that permanently inhabit in the island of IKARIA, Greece were recruited. Methods Aortic distensibility (AoD) was calculated and genetic evaluation was performed on the ACE Insertion/Deletion gene polymorphism (intron 16) and the G/A transition (position -308) of the TNF gene. Cognitive function was evaluated using the Mini-mental State Examination (MMSE). Results The DD genotype for ACE was independently associated ( b  = -0.44, P = 0.007) with AD while AoD remained an independent determinant of mental status (OR = 1.82, P = 0.036). Interestingly though, when a combined genetic index (GI) was calculated for both genes (ACE and TNF), subjects being double homozygous (DD for ACE and GG for TNF) for these loci presented significantly decreased MMSE (adjusted OR = 0.259, P = 0.033). This GI independently associated with AD (beta coefficient = -0.785, P = 0.002). When AoD was included, GI lost its predictive role (OR = 0.784, P = 0.783) towards MMSE. AoD has marginal indirect mediating effect in the association of the GI with MMSE ( P = 0.07). Conclusion Vascular aging may modulates the genetic substrate of elderly subjects on the risk for developing dementia.

ASSOCIATION OF TENDON XANTHOMAS WITH CAROTID ATHEROSCLEROSIS IN PATIENTS WITH FAMILIAL HYPERCHOLESTEROLEMIA

Background: Heterozygous familial hypercholesterolemia (hFH) is an inherited disorder of lipoprotein metabolism, which is associated with early atherosclerotic disease. Subclinical carotid atherosclerosis expressed by intima-media thickness (IMT) is a predictor of cardiovascular risk. We investigated whether the presence of tendon xanthomas is associated with carotid atherosclerosis in patients with hFH.
