RESUMO

BACKGROUND: Several studies have reported weak associations between religious or spiritual belief and psychological health. However, most have been cross-sectional surveys in the U.S.A., limiting inference about generalizability. An international longitudinal study of incidence of major depression gave us the opportunity to investigate this relationship further. METHOD: Data were collected in a prospective cohort study of adult general practice attendees across seven countries. Participants were followed at 6 and 12 months. Spiritual and religious beliefs were assessed using a standardized questionnaire, and DSM-IV diagnosis of major depression was made using the Composite International Diagnostic Interview (CIDI). Logistic regression was used to estimate incidence rates and odds ratios (ORs), after multiple imputation of missing data. RESULTS: The analyses included 8318 attendees. Of participants reporting a spiritual understanding of life at baseline, 10.5% had an episode of depression in the following year compared to 10.3% of religious participants and 7.0% of the secular group (p<0.001). However, the findings varied significantly across countries, with the difference being significant only in the U.K., where spiritual participants were nearly three times more likely to experience an episode of depression than the secular group [OR 2.73, 95% confidence interval (CI) 1.59­4.68]. The strength of belief also had an effect, with participants with strong belief having twice the risk of participants with weak belief. There was no evidence of religion acting as a buffer to prevent depression after a serious life event. CONCLUSIONS: These results do not support the notion that religious and spiritual life views enhance psychological well-being.

RESUMO

OBJECTIVES: Diet has health consequences, which makes knowing the psychological correlates of dietary habits important. Associations between dietary habits and personality traits were examined in a large sample of Estonians (N = 1,691) aged between 18 and 89 years. METHOD: Dietary habits were measured using 11 items, which grouped into two factors reflecting (a) health aware and (b) traditional dietary patterns. The health aware diet factor was defined by eating more cereal and dairy products, fish, vegetables and fruits. The traditional diet factor was defined by eating more potatoes, meat and meat products, and bread. Personality was assessed by participants themselves and by people who knew them well. The questionnaire used was the NEO Personality Inventory-3, which measures the Five-Factor Model personality broad traits of Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness, along with six facets for each trait. Gender, age and educational level were controlled for. RESULTS: Higher scores on the health aware diet factor were associated with lower Neuroticism, and higher Extraversion, Openness and Conscientiousness (effect sizes were modest: r = .11 to 0.17 in self-ratings, and r = .08 to 0.11 in informant-ratings, ps < 0.01 or lower). Higher scores on the traditional diet factor were related to lower levels of Openness (r = -0.14 and -0.13, p < .001, self- and informant-ratings, respectively). CONCLUSIONS: Endorsement of healthy and avoidance of traditional dietary items are associated with people's personality trait levels, especially higher Openness. The results may inform dietary interventions with respect to possible barriers to diet change.

RESUMO

BACKGROUND: More than one third of adult population in Estonia has problems with elevated blood pressure (BP). The Hypertension in Estonia (HYPEST) study represents the country's first hypertension-targeted sample collection aiming to examine the epidemiological and genetic determinants for hypertension (HTN) and related cardiovascular diseases (CVD) in Estonian population. The HYPEST subjects (n = 1,966) were recruited across Estonia between 2004-2007 including clinically diagnosed HTN cases and population-based controls. The present report is focused on the clinical and epidemiological profile of HYPEST cases, and gender-specific effects on the pathophysiology of hypertension. METHODS: Current analysis was performed on 1,007 clinically diagnosed HTN patients (617 women and 390 men) aged 18-85 years. The hypertensives were recruited to the study by BP specialists at the North Estonia Medical Center, Centre of Cardiology, Tallinn or at the Cardiology Clinic, Tartu University Hospital, Estonia. Longitudinal BP data was extracted retrospectively from clinical records. Current and retrospective data of patient's medical history, medication intake and lifestyle habits were derived from self-administrated questionnaire and each variable was examined separately for men and women. Eleven biochemical parameters were measured from fasting serum samples of 756 patients. RESULTS: The distribution of recruited men and women was 39% and 61% respectively. Majority of Estonian HTN patients (85%) were overweight (BMI ≥ 25 kg/m2) and a total of 79% of patients had additional complications with cardiovascular system. In men, the hypertension started almost 5 years earlier than in women (40.5 ± 14.5 vs 46.1 ± 12.7 years), which led to earlier age of first myocardial infarction (MI) and overall higher incidence rate of MI among male patients (men 21.2%, women 8.9%, P < 0.0001). Heart arrhythmia, thyroid diseases, renal tubulo-intestinal diseases and hyperlipidemia were more prevalent in hypertensive women compared to men (P < 0.0001). An earlier age of HTN onset was significantly associated with smoking (P = 0.00007), obesity (BMI ≥ 30 kg/m2; P = 0.0003), increased stress (P = 0.0003) and alcohol consumption (P = 0.004). CONCLUSION: Understanding the clinical profile of HTN patients contributes to CVD management. Estonian hypertension patients exhibited different disease and risk profiles of male and female patients. This well-characterized sample set provides a good resource for studying hypertension and other cardiovascular phenotypes.

RESUMO

AIM: The aim of this study was to determine the associations between the level of HIV knowledge, HIV-related risk behaviours, and HIV status among persons receiving voluntary counselling and testing services in Tallinn, Estonia. DESIGN: A cross-sectional study design was used. METHODS: A total of 772 subjects completed a 47-item questionnaire gathering information on demographics, HIV-related risk behaviours, and HIV-related knowledge. Participant's HIV status was determined by an anonymous rapid test. Only incident HIV cases were included in regression analyses. An analysis of covariance (ANCOVA) modelling evaluated associations between HIV knowledge and high-risk behaviours while multivariable logistic regression assessed association between HIV status and HIV knowledge. RESULTS: The final ANCOVA model indicates that HIV risk behaviours are significantly associated with HIV knowledge (p = 0.01). Compared to participants with no identified high-risk behaviour, the adjusted mean score of HIV knowledge was higher among persons sharing injection equipment (p = 0.05), and persons engaging in unprotected heterosexual intercourse (p = 0.03); there was no statistical difference observed among men engaging in unprotected sex with other men. Women had higher mean scores than men (p = 0.01) and persons of ''other'' ethnicities had a higher mean knowledge score than ethnic Estonians (p = 0.01) and Russians (p < 0.01). Logistic regression indicated that mean knowledge was higher among participants who tested HIV positive (OR = 1.42; 95% CI = 1.12-1.87). CONCLUSIONS: In this sample, higher knowledge scores were not associated with lower infection rates. These results indicate the importance of targeting all high-risk groups in HIV prevention and education programmes.

RESUMO

AIMS: The aim of the study was to describe trends in alcoholic liver cirrhosis mortality rates in 1992-2008 and to examine socio-demographic differences in alcoholic liver cirrhosis mortality. METHODS: Individual records of deaths from alcoholic liver cirrhosis among 25-64-year olds in 1992-2008 in Estonia were analysed. Age-standardized mortality rates for men and women aged 25-44 and 45-64 were calculated. Association between alcoholic liver cirrhosis mortality and socio-demographic variables (age, education and ethnicity) for the data of the years around the census in 2000 was measured by mortality rate ratios using Poisson regression models. RESULTS: In 1992-2008, alcoholic liver cirrhosis mortality rates were higher among men than that in women and that in the older than in the younger age group. Over the whole study period, mortality from alcoholic liver cirrhosis increased steeply. The increase was sharper among men and women in the older age group. In 1998-2001, higher alcoholic liver cirrhosis mortality rates occurred in non-Estonians and those with lower levels of education. CONCLUSION: Alcoholic liver cirrhosis mortality has increased steadily in Estonia, and is reflected in an increase in heavy drinking. National alcohol policies should address all strata of society. However, in order to reduce alcohol-related damage in the population most effectively, special attention should be paid to non-Estonians and people with low levels of education.

RESUMO

AIM: To compare self-perceived health in relation to socioeconomic factors in Estonia and Finland. METHODS: This study was based on the 25-69 year old adult population of the European Social Survey, conducted in Estonia and in Finland in 2006. Self-perceived health was rated on the five-point scale as very good, good, fair, poor, and very poor. The socioeconomic position was measured by the level of education, economic activity, and self-rated financial situation. Logistic regression analysis was applied to assess the association between self-perceived health and the socioeconomic factors. RESULTS: The prevalence of less-than-good health was significantly higher in Estonia than in Finland. Significant associations with less-than-good self-perceived health were found for less educated, economically non-active respondents with poorer self-rated financial situation in both countries. After adjustment, economic non-activity among women and self-rated financial situation among men appeared not to be associated with less-than-good self-perceived health in Finland. CONCLUSIONS: Self-perceived health was poorer in Estonia than in Finland, but Estonia shares with Finland a similar socioeconomic pattern of health. Further research is needed to monitor socioeconomic variations in health behaviour and mortality in both countries.

RESUMO

In the nineteenth century, the transition from a Baltic-German-controlled manor-and-serf economy to individually owned farmsteads transformed all aspects of life including the spatial organization and form of farmhouses in the western provinces of Tsarist Russia. Agricultural experts and social reformers discussed how to update the traditional threshing-room dwelling house (rehielamu) into a healthy dwelling for successful farmers and, after the Estonian War of Independence, for new settlers. Using material culture such as contemporary plans, I show that changing household relationships, in addition to economic and technological factors, helped to transform the ancient rehielamu into a modern dwelling.

RESUMO

While identity construction continues to be a widely discussed and researched area in contemporary social sciences, the existing theories have overlooked the importance of understanding why and how identities as semiotic constructions emerge in individuals' consciousness in the flow of their everyday functioning. This article seeks to address this limitation in the theorizing by proposing an alternative conceptualization of identity, according to which identity construction is triggered by rupturing life-experience, which surfaces another perspective and makes the person aware of a possibility to be otherwise or of the reality of being different. Theoretical claims put forward in the paper are drawn from data gathered in a recent study, which explored lived-through experiences of young Estonians, who made study-visits to the United Kingdom. The discussed data will also highlight some interesting aspects in Estonians' self-definition as it is constructed in relation to Eastern-European identity in the context of contemporary Britain.

RESUMO

This study was a longitudinal investigation of the three different dimensions of long-term immigrant adaptation (i.e., psychological, sociocultural, and socioeconomic adaptation) and the relationships between them in an 8-year follow-up with panel data. The 282 respondents were immigrants in Finland, born between 1961 and 1976, coming from the former Soviet Union. The results suggest that the adaptation of these immigrants has developed favourably. In 8 years, the respondents had improved their Finnish language skills and their position in the labour market. No differences were observed in their levels of psychological well-being between the two assessments. Of the three adaptation dimensions assessed, sociocultural adaptation, measured as proficiency in understanding, speaking, reading, and writing Finnish, turned out to be the most significant predictor of the two other long-term outcomes of immigrant adaptation (i.e., socioeconomic and psychological). In particular, the better the initial command of the Finnish language, the better were their socioeconomic and psychological adaptation outcomes after 8 years of residence. These results demonstrate the importance of parallel and longitudinal assessments of the different outcomes of immigrant adaptation in order to address which particular dimensions of adaptation are most critical in the beginning of acculturation in terms of determining positive development and long-term immigrant adaptation. This study was supported by City of Helsinki Urban Facts. The author gratefully acknowledges the assistance of Anniina Lahtinen and Riku Perhoniemi in the data collection, and in addition, Riku Perhoniemi for the preliminary data analysis, and advice on the Amos analyses. Cette étude longitudinale a examiné trois différentes dimensions de l'adaptation à long-terme de l'immigré (i.e., adaptation psychologique, socio-culturelle et socio-économique) et de la relation entre elles dans un suivi de 8 ans avec des données de panel. Les 282 répondants étaient des immigrés en Finland provenant de l'ancienne Union Soviétique nés entre 1961 et 1976. Les résultats suggèrent que l'adaptation de ces immigrants s'est développée favorablement. En huit ans, les répondants avaient amélioré leurs habiletés en finlandais sur le marché de travail. Aucune différence n'a été observée dans leurs niveaux de bien-être psychologique entre les deux évaluations. Parmi les trois dimensions de l'adaptation évaluées, l'adaptation socio-culturelle telle que mesurée par la capacité de comprendre, de parler, de lire et d'écrire le finlandais s'est avérée être le prédicteur le plus significatif des deux autres résultats à long-terme de l'adaptation de l'immigré (i.e., socio-économique et psychologique). Particulièrement, meilleure avait été la connaissance initiale du finlandais, meilleurs étaient leurs résultats de l'adaptation socio-économiques et psychologiques après 8 ans de résidence. Ces résultats démontrent l'importance des évaluations parallèles et longitudinales de différents résultats de l'adaptation de l'immigré pour mieux étudier quelles dimensions particulières de l'adaptation sont les plus critiques au début de l'acculturation en matière de la détermination du développement positif et de l'adaptation à long-terme de l'immigré. El estudio consistió en una investigación longitudinal sobre tres diferentes dimensiones de adaptación de inmigrantes a largo plazo (i.e. adaptación psicológica, sociocultural, socioeconómica) y la relación entre ellas en 8 años de seguimiento con los datos de grupo. Los 282 encuestados fueron inmigrantes en Finlandia procedentes de los países de la antigua Union Sovietica, nacidos entre 1961 y 1976. Los resultados sugieren que la adaptación de estos inmigrantes se desarrolló favorablemente. En ocho años, los encuestados han mejorado sus conocimientos del idioma finlandes y su posición en el mercado laboral. No se observó ningunas diferencias en su nivel del bienestar psicológico entre las dos evaluaciones. Entre las tres dimesiones de adaptación que fueron evaluadas, adaptación sociocultural, medida como aptitud de comprensión, habla, lectura y escritura en finlandes fue el predictor más significante de los resultados en otras dimensiones de adaptación de los inmigrantes a largo plazo (i.e. socioeconómica y psicológica). Particularmente, cuando mejor era el dominio inicial del idioma finlandes, mejores eran los resultados de adaptación socioeconómica y psicológica después de 8 años de residencia. Estos estudios demuestran la importancia de la evaluación en paralelo y longitudinal de diferentes resultados de adaptación de los inmigrantes para saber cuáles particulares dimensiónes de adaptación son las más críticas en el principio de aculturación para determinar el desarrollo.

RESUMO

BACKGROUND: The purpose of the study was to estimate the proportion of alcohol abuse and dependence (AAD) among suicides and controls, and to compare the incidence of AAD documented by clinicians with diagnoses derived from a research protocol. METHOD: AAD according to DSM-IV was diagnosed on the basis of interviews with relatives of people who committed suicide and with controls. A total of 427 people who committed suicide during one year were paired by region, gender, age and nationality with controls randomly selected from general practitioners' lists. RESULTS: Alcohol abuse was found in 10% and alcohol dependence in 51% of suicide cases. The corresponding figures for controls were 7% and 14% respectively. AAD was a statistically significant predictor of completed suicides, while abstinence was a significant predictor for female suicides and former use a significant predictor for older male suicides. AAD was diagnosed in 68% of male and 29% of female suicides. Middle-aged (35-59 years) males who committed suicide had the highest risk of alcohol dependence. Among suicide cases only 29% had received a lifetime diagnosis of AAD, against 23% of controls. CONCLUSIONS: AAD was significantly more prevalent among suicides than controls. Overall, the proportion of male suicides affected by alcohol was the same in the present psychological autopsy study as in our previous findings for Estonia on the aggregate level, while the share of female suicides with an AAD diagnosis was dramatically higher on the individual level. AAD is markedly underdiagnosed by general practitioners and clinicians.

RESUMO

A discussion of Nazi anti-Gypsy policy in Estonia needs to center on local interpretation and implementation of RSHA and RKO orders. Contradictions between various German instructions, which often discriminated among sedentary and itinerating Gypsies, created a state of confusion that increased chances for survival. Since in Estonia Sonderkommando 1a of the German Security Police exercised oversight rather than itself carrying out atrocities, the destruction of the Gypsy community in Estonia proceeded at a pace slower than elsewhere in Eastern Europe. Interested in exploiting slave labor, the German Security Police in Estonia did not consider liquidation of the Gypsies a priority. Acculturated to traditional anti-Gypsy prejudices and burdened by their own wartime travails, the majority of Estonians remained indifferent when Estonian police deported Gypsies.

RESUMO

The mtDNA polymorphism was analyzed in eight ethnic groups (N = 979) of the Volga-Ural region. Most mtDNA variants belonged to haplogroups H, U, T, J, W, I, R, and N1 characteristic of West Eurasian populations. The most frequent were haplogroups H (12-42%) and U (18-44%). East Eurasian mtDNA types (A, B, Y, F, M, N9) were also observed. Genetic diversity was higher in Turkic than in Finno-Ugric populations. The frequency of mtDNA types characteristic of Siberian and Central Asian populations substantially increased in the ethnic groups living closer to the Urals, a boundary between Europe and Asia. Geographic distances, rather than linguistic barriers, were assumed to play the major role in distribution of mtDNA types in the Volga-Ural region. Thus, as concerns the maternal lineage, the Finno-Ugric populations of the region proved to be more similar to their Turkic neighbors rather than to linguistically related Balto-Finnish ethnic groups.

RESUMO

Four hundred and forty two adult individuals of Estonian nationality were examined in different regions of Estonia for the C282Y and H63D HFE mutations to determine the allele and genotype frequencies. The sample consisted only of those people whose at least four grandparents were born in Estonia, and have lived settled in the same region. The study was carried out using the PCR technique and restriction analysis for C282Y and H63D mutations respectively. For the C282Y mutation the frequency of heterozygotes was 6.6% and homozygotes 0.2%, giving allele frequency 0.035. The allele frequency for the H63D mutation was 0.136, and the frequency of homo- and hetero-zygotes 1.6% and 24.0% respectively.

RESUMO

A comparison of 4 subsamples with the Ethnic Identity Scale (developed for the present study) yielded 2 relatively independent facets of ethnic identity: ethnic pride and belonging (EP) and ethnic differentiation (ED). First, the distinction between EP and ED increased understanding of how age and immigration status affect changes in ethnic identity. In a comparison of Estonians living in Sweden with those living in Estonia, only ED was affected by emigration and contacts with other ethnic groups, although both EP and ED were positively correlated with age. Second, the distinction between EP and ED increased understanding of earlier and seemingly contradictory findings about the connection between ethnic identity and ethnic attitudes. In the present study, EP was not correlated with ethnic attitudes, but, for 2 majority groups, ED was positively correlated with negative evaluations of out-groups. The authors also discuss the role of group status and relationships with the target nation in understanding the relationship between ethnic identity and ethnic attitudes.

RESUMO

Studies of workers who were sent to Chernobyl after the 1986 reactor accident are being conducted to provide a better understanding of the effects of chronic low-dose radiation exposures. A crucial component to these investigations is an accurate assessment of the radiation doses received during the cleanup activities. To provide information on biological measurements of dose, fluorescence in situ hybridization (FISH) with whole-chromosome painting probes has been applied to quantify stable chromosome aberrations (translocations and insertions) among a defined cohort of 4,833 cleanup workers from Estonia. Cytogenetic analysis of 48-h lymphocyte cultures from 118 Estonian cleanup workers (10.3 cGy mean recorded dose; 25 cGy maximum), 29 Estonian population controls and 21 American controls was conducted by three laboratories. More than 258,000 painted metaphases were evaluated. Overall, we observed lower translocation frequencies than has been reported in previous studies using FISH among Chernobyl cleanup workers. In our data, a clear association with increased levels of translocations was seen with increasing age at blood drawing. There was no correlation, however, between aberration frequency and recorded measurements of physical dose or any category of potential high-dose and high-dose-rate exposure such as being sent to Chernobyl in 1986, working on the roof near the damaged nuclear reactor, working in special zones or having multiple tours. In fact, the translocation frequency was lower among the exposed workers than the controls, though not significantly so. To estimate the level of effect that would have been expected in a population of men having an average dose of approximately 10 cGy, blood from six donors was exposed to low-LET radiation, and more than 32,000 metaphases were scored to estimate dose-response coefficients for radiation-induced translocations in chromosome pairs 1, 2 and 4. Based on these results, we estimate that had this group of 118 men received an average whole-body dose of 10-11 cGy, as chronic or acute exposures, an increase in the mean frequency of chromosome translocations of more than 40-65% would have been observed in their lymphocytes compared to findings in nonirradiated controls. In spite of evaluating more than a quarter of a million metaphases, we were unable to detect any increase in the mean, median or range in chromosome aberrations in lymphocyte cultures from a group of Estonian men who took part in the cleanup of the Chernobyl nuclear power site and those who did not. We conclude that it is likely that recorded doses for these cleanup workers overestimate their average bone marrow doses, perhaps substantially. These results are consistent with several negative studies of cancer incidence in Chernobyl cleanup workers and, if borne out, suggest that future studies may not be sufficiently powerful to detect increases in leukemia or cancer, much less distinguish differences between the effects of chronic compared to brief radiation exposures.

OBJECTIVE: To compare the prevalence of Raynaud's phenomenon (RP) in 2 genetically different ethnic groups in Estonia: Estonians, who are Finno-Ugric people, and Slavs, who are Indo-European people, and to investigate the risk factors of RP. METHODS: A random sample of 5248 Estonians and 4341 Slavs were surveyed by mail questionnaire (Phase I) for suspected RP. A subsample of 1739 subjects was interviewed and examined (Phase II) to make a formal diagnosis of RP, using the color charts, and to collect additional pertinent information. RESULTS: Of these 1739 subjects examined in Phase II, 226 women and 162 men were diagnosed to have RP. The age adjusted prevalence of RP was significantly higher among Slavs (women 11.4 +/- 1.3%, men 13.0 +/- 1.6%) compared to Estonians (women 7.8 +/- 1.0%, p = 0.023; men 8.2 +/- 1.5%, p = 0.031). Based on logistic regression analysis, the diagnosis of RP among women was associated with a Slavic ethnic origin, the presence of connective tissue disorders or cardiovascular diseases, a family history of RP, a history of dysphagia and frostbite, smoking, and a lower body mass index (BMI). Among men RP was associated with manual work, vibrating tool use, a history of frostbite and injuries to the fingers. older age, and a lower BMI. CONCLUSION: Our results revealed a significant difference in the prevalence of RP between 2 ethnic groups living in the same geographic region. The risk factors associated with RP show considerable sex differences, RP being mostly constitutional in women and occupational in men.
