RESUMEN

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.

RESUMEN

Objective To analyze a profile of hypotensive drug therapy in patients with arterial hypertension (АH) aged 55-84 in a sample of urban population at a current period of time (2015-2017).Materials and Methods AH is a leader among risk factors of cardiovascular diseases (CVD) due to its high prevalence and serious prognosis. Despite the availability of effective hypotensive drugs and guidelines on AH treatment, 50% of patients do not achieve blood pressure (BP) goals. Knowledge about drug correction of AH in the Russian population is limited to clinical studies. Taking into account changing approaches in management of patients with AH, the population-based evaluation of hypotensive treatment if relevant. A random population sample of males and females aged 55-84 (n=3.898) was evaluated in Novosibirsk in 2015-2017 (international project, Health, Alcohol and Psychosocial Factors in Eastern Europe (HAPIEE)). AH was diagnosed in presence of systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg and/or treatment with hypotensive drugs within the recent two weeks. Regular intake of medication for 12 months was evaluated with coding according to the Anatomic Therapeutic Chemical Classification System (АТХ / АТС).Results In the population sample aged 55-84, AH prevalence was 80.9 %, and 21.1 % of persons with AH did not receive drug therapy. Hypotensive medicines included (total/as a part of combination therapy) angiotensin-converting enzyme (ACE) inhibitors (42.3 % / 25.3 %), angiotensin II receptor blockers (ARBs) (30.3 % / 18.9 %), diuretics (22.6 % / 20.4 %), calcium channel blockers (20.2 % / 16.1 %), and beta-blockers (34.7 % / 27.6 %). 45.7 % of people with AH received a combination therapy. Effective BP control was achieved in 23.4 % of AH patients and in 29.6 % of patients receiving a hypotensive therapy. In the group of ineffective BP control, the proportion of females was lower, AH duration was longer, and blood glucose was higher than in the group of effective control.Conclusion In the sample of urban population aged 55-84 in 2015-2017, each fourth participant with AH and each third participant using hypotensive drugs achieved effective BP control. The therapy profile in AH patients included recommended drug classes. However, combination therapy was used insufficiently (50% of AH patients). By frequency of use, ACE inhibitors were on the first place, beta-blockers were on the second place, ARBs were on the third place, diuretics were on the fourth place, and calcium channel blockers were on the fifth place, which differed from the guidelines (the difference from the recommended priority ranking is that the drugs taking the first places in the guidelines were in fact on the 3rd and 4th places in their actual frequency of use). 20% of persons with AH did not receive hypotensive therapy, which significantly contributed to the insufficient BP control in the population.

RESUMEN

We used quantitative real-time PCR method to analyse mtDNA copy number in a random subsample (n=996; 358 men aged 66,31±7,24 years; 468 women aged 67,62±7,1 years) selected from a population cohort (n=9 630) examined at baseline in international project HAPIEE in Novosibirsk, Russia, in 2003-2005. The participants were re-examined after 12 years in 2015-2017. The average relative number of mtDNA copies in peripheral blood leukocytes was greater in women than in men, independently of age and smoking (p=0,001). mtDNA copy number was inversely correlated with age both in men (p=0,005) and women (p<0,001). In age adjusted analysis, mtDNA copy number was inversely associated with waist, hip and heart rate in both sexes. In addition, mtDNA copy number in women was inversely associated with triglycerides and glucose, aterogenity index and positively with HDL cholesterol. In men, mtDNA copy number was positively associated with physical activity. The age-adjusted mean of mtDNA copy number among male never-smokers was greater than in smokers (p=0,003), and the mean mtDNA copy number was lower in women with diabetes than in women without diabetes (p=0,005). In both sexes, subjects with baseline history of hypertension had lower mtDNA copy number after 12-year follow-up than those without hypertension (p=0,05). This broadly supports the hypothesis that mtDNA copy number may act as biomarker of ageing.
