Association of the APOE Gene Polymorphism with Depression in White Adults in the WHO "MONICA-Psychosocial" Program

The APOE gene polymorphism is associated with the risk of the development of several neurological disorders. The aim of the study was to investigate the association of the APOE gene polymorphism with depression in the white adult population aged 25-64 years in Novosibirsk (Western Siberia). The third screening of the WHO program "MONICA-psychosocial" was conducted in 1994-1995. In total, 403 men (the average age was 34 ± 0.4 years, the response was 71%) and 531 women (the average age was 35 ± 0.4 years, the response was 72%) of the open population of residents aged 25-64 years of the Oktyabrsky district of Novosibirsk were examined. The "MONICA-MOPSY" psychosocial questionnaire was used to assess depression. A high level of depression was found in 12.8% of the population: in 8.9% of men and in 15.8% of women. The frequencies of APOE gene polymorphism genotypes ε2/3, ε2/4, ε3/3, ε3/4, and ε4/4 were 14.9%, 3.1%, 61.6%, 17.5%, and 2.9%, respectively. Carrying the ε3/4 genotype of the APOE gene increased the odds of developing major depression by 2.167 times (95% CI 1.100-4.266) compared to carrying the ε3/3 genotype of the APOE gene in people without depression (χ2 = 5.120 df = 1 p = 0.024). Carriers of the ε4 allele were 2.089 times (95% CI 1.160-3.761) more likely to have a high level of depression than those without this allele and no depression (χ2 = 6.148 df = 1 p = 0.013), and 2.049 times (95% CI 1.117-3.758) more likely to have a moderate level of depression than those without this allele (χ2 = 5.470 df = 1 p < 0.019). The ε4 allele of the APOE gene is associated with a high level of depression.

Association of Common Variants of APOE, CETP, and the 9p21.3 Chromosomal Region with the Risk of Myocardial Infarction: A Prospective Study

The individual risk of an unfavorable cardiovascular outcome is determined by genetic factors in addition to lifestyle factors. This study was aimed at analyzing possible associations of several genetic factors with the risk of myocardial infarction (MI). For our study, we selected genes that have been significantly associated with MI in meta-analyses: the chromosomal region 9p21.3, the CETP gene, and the APOE gene. In total, 2286 randomly selected patients were included. Rs708272 and rs429358 and rs7412 were analyzed using RT-PCR via the TaqMan principle, and rs1333049 vas analyzed via a commercial KASP assay. In our sample, the frequencies of alleles and genotypes were consistent with frequencies in comparable populations of Eastern and Western Europe. Allele C of rs1333049 was significantly associated with MI among males (p = 0.027) and in the whole study sample (p = 0.008). We also revealed a significant association of the ɛ2/ɛ4 genotype of APOE with MI among males (p < 0.0001) and in the whole study sample (p < 0.0001). Thus, among the tested polymorphisms, some genotypes of rs1333049 and rs429358 and rs7412 are the most strongly associated with MI and can be recommended for inclusion into a genetic risk score.

Associations of APOE Gene Variants rs429358 and rs7412 with Parameters of the Blood Lipid Profile and the Risk of Myocardial Infarction and Death in a White Population of Western Siberia

The present study aimed to analyze possible associations of rs7412 and rs429358 of the APOE gene with lipid profile parameters, the risk of myocardial infarction, and death in the mostly white population of Western Siberia (Russia). The study population was selected from a sample surveyed within the framework of the Health, Alcohol and Psychosocial Factors In Eastern Europe (HAPIEE) study (9360 subjects, age 53.8 ± 7.0 years, males/females 50/50). PCR was conducted with fluorescence detection according to the TaqMan principle on a real-time PCR machine. The frequency of a minor allele (C) of rs429358 was 0.13, and the frequency of a minor allele (T) of rs7412 was 0.09. In our study, the woman with the rare ɛ1/ɛ4 genotype had substantial aberrations in blood lipid levels. In Kaplan–Meier curves, statistically significant differences were revealed in the prognosis of survival within the subgroup of females who had a myocardial infarction (p = 0.0006): the prognosis was worse for carriers of the ɛ2/ɛ2 genotype and for ɛ4/ɛ4 carriers. Survival analysis regarding deaths from all causes showed (p = 0.0238) that female carriers of the ɛ2/ɛ4 genotype had a worse prognosis than did carriers of other genotypes. Thus, in the population of Western Siberia (Russia), we confirmed statistically significant associations between rs7412 & rs429358 genotypes and lipid profile parameters.

The Relationship between Epigenetic Age and Myocardial Infarction/Acute Coronary Syndrome in a Population-Based Nested Case-Control Study

We investigated the relationship between ‘epigenetic age’ (EA) derived from DNA methylation (DNAm) and myocardial infarction (MI)/acute coronary syndrome (ACS). A random population sample was examined in 2003/2005 (n = 9360, 45–69, the HAPIEE project) and followed up for 15 years. From this cohort, incident MI/ACS (cases, n = 129) and age- and sex-stratified controls (n = 177) were selected for a nested case-control study. Baseline EA (Horvath’s, Hannum’s, PhenoAge, Skin and Blood) and the differences between EA and chronological age (CA) were calculated (ΔAHr, ΔAHn, ΔAPh, ΔASB). EAs by Horvath’s, Hannum’s and Skin and Blood were close to CA (median absolute difference, MAD, of 1.08, –1.91 and –2.03 years); PhenoAge had MAD of −9.29 years vs. CA. The adjusted odds ratios (ORs) of MI/ACS per 1–year increments of ΔAHr, ΔAHn, ΔASB and ΔAPh were 1.01 (95% CI 0.95–1.07), 1.01 (95% CI 0.95–1.08), 1.02 (95% CI 0.97–1.06) and 1.01 (0.93–1.09), respectively. When classified into tertiles, only the highest tertile of ΔAPh showed a suggestion of increased risk of MI/ACS with OR 2.09 (1.11–3.94) independent of age and 1.84 (0.99–3.52) in the age- and sex-adjusted model. Metabolic modulation may be the likely mechanism of this association. In conclusion, this case-control study nested in a prospective population-based cohort did not find strong associations between accelerated epigenetic age markers and risk of MI/ACS. Larger cohort studies are needed to re-examine this important research question.

Sex differences and trends of self-rated health in population aged 25-64 years from 1988 to 2017

Aim

To determine gender differences in the dynamic of self-rated health in an open population of 25-64 years over 29 years in Russia.

Methods

Within the framework of the screening in 1988-89 under the WHO MONICA-psychosocial (MOPSY) program (n = 1676, 49.5% males, mean age 44.1±0.4y), MOPSY screening in 1994-95 (n = 1527, 43% males, 44.85 ± 0.4y), in 2003-2005 under the international project HAPIEE (n = 1650, 34.9% males, 54.25±0.2y), in 2013-2016 (n = 975, 43.8% males, 34.5±0.4y) and 2016-2017 (n = 663, 41.3% males, 51.95±0.32y) within the framework of the budgetary theme No. AAAA-A17-117112850280-2, random representative samples of men and women in one of districts in Novosibirsk were examined. Self-rated health was assessed using the questionnaire ‘Knowledge and attitude towards own's health'.

Results

Rates of negative self-reported health in open population was extremely high in 1988. The share of women who consider themselves healthy was 13.7%, men - 37.9%. Gender differences increased with age. Only 10.5% of women and 29.7% of men had no complaints about their health. In 2013, there was an increase in positive health estimation among males and females and a decrease in the frequency of complaints, especially in female part of the population - by 2-2.5 times. The favorable trend which began in 2013 continued in 2017, when men and women more often self-esteemed own health status as “good” compared to earlier periods of observation. The proportion of women believed that taking comprehensive care of their health rose to 15% by 2017, equaling that of men. With the exception of 2013, women were more likely than men to report that “taking care of their health is not enough”, although by 2017 this proportion had dropped to 20%.

Conclusions

Sex differences in self-rated health increase with age, but the frequency of health complaints increases proportionally in men and women. There were found favorable tendencies in assessments of health, especially in female population.

Key messages

Rates of negative self-reported health in open population was extremely high in 1988 but subsequently favorable tendencies in assessments of health was found by 2017. Sex differences in self-rated health increase with age, but the frequency of health complaints increases proportionally in men and women.

The relationship between epigenetic age and myocardial infarction/acute coronary syndrome and in a population based nested case-control study

Background

The measure of “epigenetic age” (EA) derived from DNA methylation (DNAm) is considered as biomarker of ageing.

Objective

We investigated the relationship between EA and Myocardial Infarction (MI) /Acute coronary syndrome (ACS) in a nested case-control study of the elderly population.

Methods

A random population sample was examined at baseline (2003/05, n=9360, age 45–69, the Russian arm of the HAPIEE Project), re-examined in 2006/08, 2015/17, and followed up for an average 15 years for fatal and non-fatal events. Using a nested case-control study design, we selected participants with incident MI/ACS (cases) and age-and sex-stratified controls among those free from baseline CVD. We performed DNAm profiling of the whole blood samples (using Illumina EPIC arrays) collected at baseline. After quality control, 135 cases and 185 controls were included in the analysis. Baseline EA was calculated using Horvath, Hannum, PhenoAge and Skin and Blood DNAm clocks; the differences between EA and chronological age (CA) were denoted as DAHr, DAHn, DAPh, DASB, respectively.

Results

DNAm ages calculated with Horvath's, Hannum's and Skin and Blood clocks were close to the CA; the corresponding median absolute differences (MAD) were 3.38, 3.64 and 2.79 years, and mean (SD) −0.85 (5.37), 1.96 (5.18) and 2.10 (3.94) for DAHr, DAHn and DASB respectively. As expected, PhenoAge's predictions were less precise with MAD=9.41 and DAPh mean (SD) 8.94 (6.38). The mean DAHr and DAHn were significantly higher in MI/ACS compared to controls (0.99 (5.38) vs. −1.55 (5.27), p=0.007, and 2.89 (6.37) vs. 1.28 (4.95), p=0.006 correspondingly), DASB was borderline higher in MI/ACS vs controls and DAPh was similar in cases and controls. After controlling for sex, the risk of MI/ACS was higher in DAHr terciles 2 and 3 vs. tercile 1 (OR=1.08 [95% CI 0.61–1.89], p=0.799 and OR=2.09 [1.19–3.66], p=0.010); the association was independent of smoking but it was largely explained (or mediated) by metabolic factors (blood pressure, body mass index, total and LDL-cholesterol). Similarly, the risk of MI/ACS was increased in terciles 2 and 3 of DAHn; compared with lowest tercile, the OR were 1.52 [0.86–2.71], p=0.152 and 2.41 [1.34–4.34], p=0.003), respectively; again, the association was largely explained by metabolic factors. There was no association found between baseline DAPh or DASB and the risk of MI/ACS.

Conclusion

In this case-control study nested in a prospective population-based cohort, we found an association between acceleration of epigenetic age and increased risk of MI/ACS independent of sex and smoking. The risk of MI/ACS was about 2-fold higher in the top tercile of difference between epigenetic and chronological age. The excess risk is appeared to be modulated by metabolic factors.

Sex differences in the effect of family stress on risk of myocardial infarction and stroke in population 25–64 years: WHO program MONICA-psychosocial

Purpose

To determine the influence of family stress on the risk of cardiovascular diseases (myocardial infarction and stroke) in an open population aged 25–64 years in Russia / Siberia.

Methods

Within the framework of the III screening of WHO's MONICA-psychosocial program, a random representative sample of the population of both sexes of 25–64 years of Novosibirsk in 1994 (men n=657, mean age 44,3±0,4y, response 82.1%; women: n=689, mean age 45,4±0,4y, response 72.5%) was examined. The screening included: socio-demographic data, the definition of the family stress. New-onset cases of MI and stroke in women - 15 and 35 cases and in men - 30 and 22 cases, respectively detected in the cohort over follow-up period in frame of budgetary theme # AAAA-A17–117112850280–2.

Results

In the open population aged of 25–64 years the prevalence of high family stress was higher in men (31.5%) than women (20.9%). The risk of myocardial infarction in men and women experiencing stressful situations in the family was 5.9 and 5.58-fold higher, respectively over 16-year period. The most significant risk factors for the development of myocardial infarction were divorce (HR = 3.9) and widowhood (HR = 6.3). The risk of developing a stroke was 3.45-fold higher in men and 3.52-fold higher in women with family stress. The risk of developing stroke was higher among those with high school and elementary education levels, both in men (HR = 3.9 and HR = 6.3) and women (HR = 2.87 and HR = 3.33).

Conclusion

Stress in the family is more common in men within the working-age population. Family stress increases the risk of developing both myocardial infarction and stroke among men and women.

Gender differences in risk of myocardial infarction and stroke in population with sleep disorders in Russia / Siberia: population-based study MONICA-psychosocial

Funding Acknowledgements

Type of funding sources: None.

Objectives

To determine the gender differences in the effect of sleep disorders on risk of myocardial infarction (MI) and stroke in population 25-64 years over 16 years of follow-up.

Methods

Under the third screening of WHO program MONICA -Psychosocial a random representative sample of both gender aged 25- 64 years in Novosibirsk was examined in 1994 (n = 1346, male 48.8%, mean age 44,9 ± 0,4 years). The sleep assessment was performed using the Jenkins Sleep Questionnaire. There were 15 cases of new-onset MI in women and 30 in men, new-onset stroke 35 cases in women and 22 in men from 1994 to 2010.

Results

In an open population aged 25-64 years 48.6% of men and 65.9% of women had sleep disorders (p&lt; 0.001). Univariate analysis showed 2.4-fold risk of MI in those males with SD over 16-year of follow-up (95%CI 1.1-5.3; p&lt; 0.05) but not for women. MI risk was higher in those men who were never married, divorced or widowed (p for all &lt;0.01) compared to married ones. Risk of stroke was higher in men HR = 3 (95%CI 1.2-7.6;p &lt; 0.05) than in women HR = 1.9 (95%CI 1.03-3.7; p &lt; 0.05). Multivariate analysis revealed 2.8-fold risk of stroke (95%CI 1.1-7.1; p &lt; 0.05) in men and HR = 2.7 in women (95%CI 1.4-5.42;p &lt; 0.01) with SD. Stroke risk was higher in men with lower educational level and in women with college degree in those with SD.

Conclusions

Sleep disorders is a risk factor of MI in men only and stroke for both gender and negative social gradient increases cardiovascular risk.

Monoamine oxidase a gene polymorphism associated with hostility in male population of 45-64 in Russia/Siberia

Introduction

The presence of low-activity alleles of the MAOA gene increases the risk of hostility.

Objectives

To study the association of hostility with high and low-active variants of the MAOA gene in an open population of men 45-64 years.

Methods

Under the WHO International Program MONICA-psychosocial and HAPIEE a representative sample of men aged 45–64 years (n = 781 men, average age was 56.48 ± 0.2 years) examined in 2003-2005. All respondents independently completed a questionnaire on hostility. From the surveyed sample using the random number method 156 men were selected who were genotyped for MAOA-uVNTR polymorphism.

Results

It was found the level of hostility in the population of men was 60.3%. In persons with low-active alleles of the MAOA-L gene (allele 2 and 3) a high level of hostility was more common - 50.9%. The results of building a logistic regression model showed that the presence of low-active alleles (2; 3) of the MAOA gene increases the likelihood of hostility OR = 2,103 (95% CI 1,137-3,889, p = 0.018).

Conclusions

Our findings allow us to conclude that the low-active allele of the MAOA-L gene is associated with hostility.

Association between the phenotype of metabolically healthy obesity and the risk of myocardial infarction

Aim

This study aimed to investigate the associations between the metabolically healthy obesity (MHO) and the risk of myocardial infarction (MI) in a Russian population sample.

Materials and methods

A random population sample of men and women aged 45–69 years old at baseline was examined in 2003–2005 in a Russian city; after that the cohort was followed-up for 12 years on the average (2003–2016). A sub-cohort of subjects with body mass index (BMI) ≥30 kg/m2 at baseline was selected for present study (3157 individuals, 73.2% women); of those, 3008 subjects free from baseline history of MI/acute CHD was included for analysis. The data on incident myocardial infarction (MI) were ascertained from register of MI, two repeated examinations and repeated postal interviews during 12-year follow-up of the cohort. We used two definitions of MHO: by NCEP ATPIII, 2001 (the presence of 2 or less components of the metabolic syndrome) and by IDF 2005 (waist circumference (WC) ≥94 cm in men and ≥80 cm in women regardless of risk factors). Multivariable Cox regression was conducted using the SPSS package (V. 13.0).

Results

The prevalence of MHO at baseline ranged from 20% (by IDF) to 45% (by NCEPATPIII) in obese sub-cohort. Among subjects with MHO at baseline, about one half of subjects developed metabolically unhealthy obesity phenotype (MUO) during 12-years. Women were more likely to retain MHO (32%) and more frequent transited from MUO to MHO (14%) compared to men (22% and 6% by IDF criteria, correspondently) during 12 years.

The relative risk of incident MI in subjects with MUO at baseline was 1.9 times higher than in those with MHO (HR 1.9, 95% CI 1.2–2.9) by NCEPATP III. Among men, the relative risk of MI in those with MUO (by NCEP ATP III) was 2 times higher than in a group with MHO (HR 2.1, 95% CI 1.1–4.0). Among women, the relative risk of MI in those with MUO (by NCEP ATP III) was 2.2 (95% CI 1.2- 4.2) compared to MHO group. Using the IDF criteria, the relative risk of MI in MUO vs. MHO was 2.2 (95% CI 0.9–5.7) in men and 2.2 (95% CI: 0.9–5.7) in women.

Conclusions

In this study population, men aged 45–69 have more frequent progression from metabolically healthy to metabolically unhealthy obesity during 12 years compared to women. The 12-year risk of incident MI in subjects with MUO was approximately twice higher compared to MHO and the excess risk was similar in men and women.

Long-term trends in adherence to prevention in female population aged 25-44 years in Russia/Siberia

Objective

To determine the 23-year trends 1994-2016 yy of adherence towards cardiovascular diseases prevention, behavioral characteristics and awareness about the health in general female population aged 25-44 years in Russia / Siberia.

Methods

Under the third screening of the WHO program MONICA and sub-program ’MONICA-psychosocial’ (MOPSY) random representative sample of women aged 25-64 years (n = 870) were surveyed in Novosibirsk in 1994; 284 persons in group 25-44y. In 2016 within the framework of the screening studies covered by state task reg.# 01201282292 a random representative sample of women aged 25-44 years was examined in the same district of Novosibirsk (n = 540). Questionnaire MOPSY ‘Awareness and attitude towards the health’ was used to estimate adherence towards cardiovascular diseases prevention, behavioral characteristics and awareness about the health.

Results

The analysis showed there is a positive trend in self-rated health in female population aged 25-44 years. Despite this 50% of women rate their health negatively and 96% consider the existence of high chance to be ill with serious disease within next 5-10 years. Majority of women believed in the possibilities of modern medicine for the prevention of heart disease but there is extremely low level of healthcare utilization as prevention measure and it doesn’t exceed 10% in those women (p &lt; 0.05). There is a growth of job stress levels and upward trends in family status changes over 23 years in an open population of women aged 25-44 years. Some changes in behavioral status were found over 1994-2016 yy: increased share of people quit smoking and doing regular physical exercises, improved diet behavior.

Conclusions

We showed a positive trend in CVD risk factors prevention in women 25-44y. In spite of this, half of the women negatively evaluate their health and using of healthcare resources is deficient. There are adverse changes in the social gradient over the follow-up period.

Key messages

The purpose of this survey was to study the trends in awareness and attitudes towards cardiovascular prevention over 28 years (from 1988 to 2016) in an open female population of 25-44 years old. The purpose of this survey was to study the trends in awareness and attitudes towards cardiovascular prevention over 28 years (from 1988 to 2016) in an open female population of 25-44 years old.

Self-rated health and attitude to cardiovascular prevention in male population in Russia/Siberia

Objective

To establish the dynamics of the relationship to the prevention of cardiovascular disease, awareness, attitude to their health for 32 years (1984 -2016 yy.) In the open population among males 25-44 years in Russia / Siberia (Novosibirsk).

Methods

Within the framework of WHO’s MONICA-psychosocial program random representative samples of the male population aged 25-64 years in Novosibirsk were examined: 1984-85 (n = 753); 1988-89 (n = 739); 1994-95 (n = 657); 2013-2016 (n = 427), used the ’Knowledge and attitude to one’s health’ scale.

Results

During the observation period from 1984 to 2016, the number of men 25-44 years old believed that they are ’healthy’ or have ’good health’, but at the same time, the number of those who believe that their health they care clearly is not enough. Most men were of the opinion that a healthy person can develop a serious illness within the next 5-10 years. The number of those who believed that preventive measures will help to avoid some serious diseases has increased. Men began to stop working more often, if they did not feel well, the number of those who reduced their work and had a rest increased. The number of men has grown, who believe that a preventive health check is useful and who has started to observe proper nutrition. The number of men who smoke has decreased.

Conclusions

The dynamics of attitude towards the prevention of cardiovascular diseases, awareness, attitude to their health for 32 years indicates that at present health has become a value dominant due to a new understanding of the importance of health in terms of adapting to modern economic requirements.

Key messages

The purpose of our study was to study the dynamics of awareness and attitudes towards one’s health for 32 years (from 1984 to 2016) in an open population of working-age men 25–44 years old.

P4399Low social support and risk of myocardial infarction in general population in Russia/Siberia: gender disparities. WHO epidemiological program MONICA-psychosocial study

Aim

To determine the gender differences in the effect of social support on risk of myocardial infarction (MI) in an open population 25–64 years in Russia/Siberia.

Methods

Under the third screening of WHO program MONICA-Psychosocial a random representative sample of both gender aged 25- 64 years in Novosibirsk was examined in 1994 (n=1346, males 48.8%, mean age 44,9±0,4 years). Indices of close contacts (ICC) and social relations (SNI) were evaluated at the baseline by Berkman-Syme test. New-onset MI incidences were identified over 16-years (1994–2010yy) of follow-up in the cohort.

Results

The prevalence of low ICC levels was higher in men compared to women (63.9% and 57.1%, respectively); the prevalence of low SNI levels was higher in women compared to men (77.7% and 43%, respectively). The risk of MI over 16 years of follow-up was 5.2-fold higher in men (95% CI 1.947–19.383; p<0.05) and4.9-fold higher in women (1.108–21.762; p<0.05) with low ICC. Low SNI increases risk of MI in 3.1 times in men (1.138–9.247; p<0.05) and in 2.9 times in women (95% CI 1.040–8.208; p<0.05). After adjustment for social variables multivariate model showed significant results in higher risk of MI in those males who are living alone with manual occupational status and in women with low educational degree.

Conclusions

Social support is a protective factor for MI incidence both in men and women. Better social gradient improves this influence. Family status and occupation are stronger to be attributable to risk in males while level of degree in females with low social support.

The risk of hypertension in general population with anxiety traits in Russia/Siberia: Gender disparities. WHO survey MONICA-psychosocial

Objective

To determine gender differences in prevalence of anxiety traits in general population and to evaluate its impact on the risk of hypertension in men and women aged 25–64 years in the open population in Russia/Siberia.

Methods

Under the third screening of WHO program “MONICA-psychosocial” a random representative sample of the population aged 25–64 were surveyed in Novosibirsk in 1994 (n = 657 men, n = 870 women). Anxiety levels were measured by means Spielberger test. Over the 16-year period were identified 229 cases of AH in women and 46 for men. Cox-proportional regression model was used for an estimation of hazard ratio (HR).

Results

In general population aged 25–64 years at 99.5% of women and 97.5% of men had moderate and high levels of anxiety traits. In univariate Cox regression analysis model the risk incidence of arterial hypertension in women and men with high level of anxiety was 2.383-fold and 5.18-fold higher, respectively, over 5 years of follow-up. It was 1.853-fold and 5.75-fold higher over 10 years and 1.45 and 3.82 times higher over 16 years after baseline. In the multivariate Cox regression model HR of hypertension was 1648 in women with high level of anxiety; and it was 4.568-fold higher in men.

Conclusion

Despite the higher prevalence of HLA in women, the risk of developing hypertension is much higher in males.

Polymorphism neuropeptide receptor gene S (NPSR1) and sleep disturbances

Objective

To study the association gene of candidate NPSR1 rs324981 with sleep disorders in the open population of men 45–64 years of Novosibirsk.

Materials and methods

The study of the association candidate gene polymorphisms with sleep disorders was carried out during the examination of a random representative sample of men 45–69 years (n = 1770). The response rate was 61%. The median age is 56.5 year. Every 12 a man was selected for genotyping (n = 147). To assess the level of sleep was used a questionnaire which was filled with self-test. Statistical analysis was performed using SPSS-11.5.
