Abstract
OBJECTIVE to study the association of relative leukocyte DNA telomere length with death from natural causes during a 15-year follow-up in a middle-aged and elderly Siberian population. Study of the association of the relative length of leukocyte telomeres (LTL) with fatal outcomes during a 15-year follow-up of a random population sample formed in 2003-2005 (n=9 360, 45-69 years old, Novosibirsk, HAPIEE project). The main group included the persons died from natural causes (except external) without a previous history of CVD and cancer (n=609); controls were stratified by sex and age (n=799). The analysis of relative LTL at baseline was performed using quantitative real-time PCR. We estimated the odds ratio of all-cause death per 1 decile shortening of LTD as a continuous variable in a multivariable-adjusted logistic regression. The carriers of shorter telomere carriers had an increased risk of death from natural causes over the next 15 years (OR=1,37, 95% CI 1,31-1,44) per decile of LTL decrease, regardless of other factors. The risk coefficients were similar for death from CVD (1,39), cancer (1,42), and other non-external causes (1,51). In studied middle-aged and elderly Siberian (Caucasoid) population cohort the LTL was an independent inverse predictor of the 15-year risk of death from natural causes.

Abstract
We aimed to investigate the relationship between the indicators of cognitive functions (CF) and modifiable risk factors for chronic non-communicable diseases (NCD) in a cross-sectional analysis in the urban Russian population sample aged 55-84 years. The study investigated a random sample of 3 153 people (men and women 55-84 years old) from a general population cohort of Novosibirsk residents; a sample was examined within the international project HAPIEE. The study protocol included standardized neuropsychological tests (quantitative assessment of memory, semantic verbal fluency, attention and processing speed) and standardized assessment of risk factors, history and treatment of cardiovascular disease and NCD. In cross-sectional analysis we observed a positive relationship of CF indices with level of education and an inverse relationship with metabolic risk factors and smoking in both sexes. The level of total cholesterol and moderate alcohol consumption had positive relationship with CF indices in women. These associations were independent from age and other factors.

Abstract
Abstract
Background
The prevalence of cardiovascular diseases (CVD) is increasing due to the global trend towards an aging population. CVD and cerebrovascular disease have a negative impact on cognitive health, and CVD risk factors may also be associated with cognitive decline with aging.
Purpose
To investigate associations of modifiable risk factors for CVD with cognitive functions (CF) in older Russian adults.
Methods
A random population sample (3153 men and women, aged 55–84 years) was examined in our city in the 3rd wave of the Russian arm of the international project HAPIEE (Health, Alcohol, and Psychosocial Factors in Eastern Europe). We used standardized epidemiological and instrumental methods for assessment of risk factors, history and treatment of CVD. Cognitive tests included the assessment of memory indicators (immediate and delayed recall), semantic verbal fluency (animal naming), attention, concentration and processing speed (letter cancellation task). Associations between CVD risk factors and cognitive indices were analyzed cross-sectionally.
Results
Mean age in men was of 69.2±7.0 years (n=1198), in women - 69.7±6.9 (n=1955). In both sexes all cognitive domains were positively associated with education and negatively with age (p<0.001 for all cases). In men, after adjusting for health and lifestyle conditions, systolic blood pressure had inverse association with semantic verbal fluency (p=0.015); level of plasma glucose (p=0.003), waist-to-hip ratio (p=0.013) and smoking (p=0.028) were negative associated with letter cancellation task. In multivariate analyses in women, frequency of alcohol consumption (p<0.001 for all CF) and total cholesterol (p=0.042 for memory scores; p=0.001 for letter cancellation task) had positive relationship with CF indices, waist-to-hip ratio (p=0.002 for memory scores, p=0.038 for semantic fluency), level of plasma glucose (p=0.002 for memory scores, p<0.001 for letter cancellation task) and smoking (p<0.001 for letter cancellation task) had inverse relationships with cognition.
Conclusion
Our results show that metabolic risk factors (systolic blood pressure, plasma glucose, waist-to-hip ratio) and smoking had inverse relationship with CF indices in both sexes, and the level of blood lipids (total cholesterol and high-density lipoprotein cholesterol) and frequency of alcohol consumption (more pronounced in women) had positive associations with cognitive domains. These associations were independent from age. In multivariate analyses, some of these correlations were attenuated, and most associations were at least partly mediated by education. These findings highlight the importance of managing CVD risk factors to prevent cognitive decline.
