Economic fluctuations and urban-rural differences in educational inequalities in mortality in the Baltic countries and Finland in 2000-2015: a register-based study.

We examined urban-rural differences in educational inequalities in mortality in the Baltic countries (Estonia, Latvia, Lithuania) and Finland in the context of macroeconomic changes. Educational inequalities among 30-74 year olds were examined in 2000-2003, 2004-2007, 2008-2011 and 2012-2015 using census-linked longitudinal mortality data. We estimated age-standardized mortality rates and the relative and slope index of inequality. Overall mortality rates were larger in rural areas except among Finnish women. Relative educational inequalities in mortality were often larger in urban areas among men but in rural areas among women. Absolute inequalities were mostly larger in rural areas excepting Finnish men. Between 2000-2003 and 2012-2015 relative inequalities increased in most countries while absolute inequalities decreased except in Lithuania. In the Baltic countries the changes in both relative and absolute inequalities tended to be more favorable in urban areas; in Finland they were more favorable in rural areas. The overall pattern changed during the reccessionary period from 2004-2007 to 2008-2011 when relative inequalities often diminished or the increase slowed, while the decrease in absolute inequalities accelerated with larger improvements observed in urban areas. Despite substantial progress in reducing overall mortality rates in both urban and rural areas in all countries, low educated men and women in rural areas in the Baltic countries are becoming increasingly disadvantaged in terms of mortality reduction.

Excess mortality among the elderly in European countries, December 2014 to February 2015.

Since December 2014 and up to February 2015, the weekly number of excess deaths from all-causes among individuals ≥ 65 years of age in 14 European countries have been significantly higher than in the four previous winter seasons. The rise in unspecified excess mortality coincides with increased proportion of influenza detection in the European influenza surveillance schemes with a main predominance of influenza A (H3N2) viruses seen throughout Europe in the current season, though cold snaps and other respiratory infections may also have had an effect.

Risk factors for sickness absence among Estonian employees.

BACKGROUND: During the last decade, sickness absence rates in Estonia have reached the level of Nordic countries. This places Estonia in a group of countries with the highest absence rate in the European Union. Unlike Nordic countries, factors associated with sickness absence have not been studied in Estonia. AIMS: To investigate which work-related, individual and health factors, other than current illness, influence sickness absence among Estonian paid employees. METHODS: The study population consisted of 2941 employees who completed an Estonian Health Interview Survey conducted in 2006. Multiple logistic regression analysis was performed to explore associations between individual, health and work-related factors and recent sickness absence. RESULTS: Sickness absence was significantly associated with poor self-rated general health (OR = 1.82; 95% CI = 1.34-2.48), presence of chronic disease (OR = 1.66; 95% CI = 1.21-2.27), lower education (OR = 1.59; 95% CI = 1.20-2.12) and job dissatisfaction (OR = 1.74, 95% CI = 1.23-2.26) in the final multivariate model after adjustment for age and gender conclusions: Most sickness absence risk factors revealed by previous studies were only moderately associated with sickness absence in the Estonian working population. In contrast to Nordic countries, there was no gender difference or age gradient. Among workplace risk factors, job dissatisfaction was most strongly associated with sickness absence.

Avoidable mortality in Estonia: exploring the differences in life expectancy between Estonians and non-Estonians in 2005-2007.

OBJECTIVES: A considerable increase in social inequalities in mortality was observed in Eastern Europe during the post-communist transition. This study evaluated the contribution of avoidable causes of death to the difference in life expectancy between Estonians and non-Estonians in Estonia. STUDY DESIGN: Descriptive study. METHODS: Temporary life expectancy (TLE) was calculated for Estonian and non-Estonian men and women aged 0-74 years in 2005-2007. The ethnic TLE gap was decomposed by age and cause of death (classified as preventable or treatable). RESULTS: The TLE of non-Estonian men was 3.53 years less than that of Estonian men, and the TLE of non-Estonian women was 1.36 years less than that of Estonian women. Preventable causes of death contributed 2.19 years to the gap for men and 0.78 years to the gap for women, while treatable causes contributed 0.67 and 0.33 years, respectively. Cardiorespiratory conditions were the major treatable causes of death, with ischaemic heart disease alone contributing 0.29 and 0.08 years to the gap for men and women, respectively. Conditions related to alcohol and substance use represented the largest proportion of preventable causes of death. CONCLUSIONS: Inequalities in health behaviours underlie the ethnic TLE gap in Estonia, rather than inequalities in access to health care or the quality of health care. Public health interventions should prioritize primary prevention aimed at alcohol and substance use, and should be implemented in conjunction with wider social policy measures.

[Tension-free plasty in the surgery of abdominal wall hernias].

The article presents an experience with application of tension-free plasty of the anterior abdominal wall using reticular endoprostheses. New endoprostheses of Reperen are developed and applied, a method of sutureless fixation of polypropylene net in the abdominal wall tissues is proposed when performing plasty for great ventral hernias. Advantages of new methods are shown compared with analogs both in selective and in emergency surgery, in different age groups of patients. The direct and long-term postoperative results and parameters of quality of life are investigated.

[Experimental-clinical reasons for application of endoprostheses of reperen for plasty of the abdominal wall].

The work presents results of a morphological investigation of tissues in the zone of implantation of synthetic material in creation of experimental model of ventral hernia. A comparative characteristic of a reaction of tissues on reperen and polypropylene is given. A number of principal advantages of reperen as compared with polypropylene were detected in plasty of hernial hilus. An analysis of the first experience of operative treatment of hernias by nonstrain methods using reperen in clinic is made.

Suicides among cancer patients in Estonia: a population-based study.

The objective of this study was to determine the suicide risk among cancer patients in Estonia. This risk was examined in a cohort of 65,419 persons diagnosed with cancer in 1983-1998. Standardised mortality ratios (SMR) were calculated using the suicide rates of the population of Estonia as a reference. During 192,078 person-years of follow-up between 1983 and 2000, 197 suicides occurred in the cohort. An increased suicide risk was found for men (SMR=1.73; 95% Confidence Interval (CI) 1.45-2.01), but not for women (SMR=0.50; 95% CI 0.37-0.66). Men had the highest risk 90-179 days following their diagnosis (SMR=4.27; 95% CI 2.81-6.21). During this time interval, among men, the risk was more pronounced for cancers of the oesophagus (SMR=35.63; 95% CI 9.71-91.22) and pancreas (SMR=14.53; 95% CI 1.76-52.50). This study provides further evidence that cancer is a risk factor for suicide, at least in men.

Risk factors for pulmonary tuberculosis in Estonia.

OBJECTIVE: To determine the risk factors for pulmonary tuberculosis incidence in Estonia. DESIGN: In a case-control study, the cases were 248 adult tuberculosis patients treated in a hospital in Tallinn between January 1999 and June 2000, and the controls were 248 persons sampled from the Population Registry and matched to cases by sex, year of birth and county of residence. A questionnaire was administered to collect information on potential risk factors. Logistic regression was used to calculate odds ratios and 95% confidence intervals. RESULTS: The main risk factors for tuberculosis were marital status other than married, educational level less than higher, low income, having been in prison, not having own place of residence, current unemployment, current smoking, alcohol consumption, shortage of food, and contact with tuberculosis patients. Place of birth was not a risk factor. Risk of tuberculosis decreased for overweight persons whose individual economic situation had improved during the last year. CONCLUSIONS: The pattern of risk factors for pulmonary tuberculosis in Estonia was somewhat different from that in Western European countries; a large percentage of the patients were men, but were not elderly, and immigration and drug abuse did not increase the risk. Major risk factors were related to poverty and low socio-economic status.

Lung cancer in Estonia in 1968-87: time trends and public health implications.

Changes in lung cancer incidence and mortality in Estonia were studied for 20 years (1968-87). A steady upward trend was observed for men and women. The 1983-87/1968-72 age-standardized incidence rate ratio was 1.22 (95% confidence interval (CI) 1.15-1.29) in men and 1.34 (95% CI 1.16-1.54) in women. The corresponding mortality rate ratio was 1.26 (95% CI 1.18-1.34) in men and 1.35 (95% CI 1.16-1.57) in women. The age-specific incidence and mortality rates increased clearly towards the younger birth cohorts. For men and women, the increase was most evident for the age group 45-64 years. In women there was a more rapid increase in incidence and mortality than in men. It may be a result of a substantial increase of tobacco smoking, particularly among women, after the World War II. The high and still rising occurrence of lung cancer is closely related to the high prevalence of smoking; in addition, high tar yields in domestic cigarettes could have been responsible for an elevated lung cancer risk during the past decades. There is not tobacco control programme in Estonia, and existing legislation and regulations do not defend the non-smoking population.

Estonian medical birth registry 1992-1994: association of risk factors with perinatal mortality.

OBJECTIVE: To investigate the association of different maternal sociodemographic characteristics and infant sex with perinatal mortality among primiparas and multiparas. STUDY DESIGN: Analysis of routine data from the Estonian Medical Birth Registry covering the whole of Estonia. A total of 47 358 infants (including stillborns) with a birth weight 1000 g or more from 1992 through 1994 were studied. Perinatal mortality rate, crude odds ratio (OR) and adjusted OR (calculated by a logistic regression model) were used to evaluate the association. OR values were adjusted for maternal age at delivery, maternal ethnicity, educational level, residence, marital status, smoking status, history of previous abortion and infant sex. RESULTS: The perinatal mortality rate was 12.2 per 1000 total births among primiparous and 14.3 among multiparous women. The highest adjusted ORs of perinatal deaths were found in older (35 years and over) primiparas (1.78; 95% confidence interval (CI 0.88-3.57)) and multiparas (1.81; 95% CI 1.29-2.55), in unmarried (single) primiparas (1.59; 95% CI 1.14-2.20) and multiparas (1.98; 95% CI 1.29-3.05), in smoking primiparas (1.69; 95% CI 1.09-2.63) and multiparas (1.51; 95% CI 1.02-2.25), and in multiparas with unknown smoking status (1.98; 95% CI 1.18-3.33). CONCLUSION: The study provides further evidence that perinatal mortality is positively associated with increased maternal age, unmarried (single) status and smoking.

PIP: This study was conducted to investigate the association of different maternal sociodemographic characteristics and infant sex with perinatal mortality among primiparas and multiparas. The data were based on the Estonian Medical Birth Registry (EMBR) which maintains a database of all infants born in hospitals and of the few home deliveries. From 1992 to 1994, 47,022 live births and 336 stillbirths were recorded in the EMBR. Of mothers younger than 20 years old, 26.5% were primiparous and 2.8% were multiparous; among mothers aged 35 years and older, 1.8% were primiparous and 12.0% were multiparous. Results showed that the perinatal mortality rate was 12.2%/1000 total births among primiparous and 14.3% among multiparous women. The highest adjusted odds ratios of perinatal deaths were found in older (35 years and up) primiparas (79%) and multiparas (1.8%); in unmarried primiparas (1.5%) and multiparas (2.0%); in smoking primiparas (1.7%) and multiparas (1.5%); and in multiparas with unknown smoking status (2.0)%. Therefore, perinatal mortality in Estonia was positively associated with increased maternal age, unmarried (single) status, and smoking.

Cancer patient survival in Estonia 1995-2009: time trends and data quality.

BACKGROUND: Survival from most cancers in Estonia has been consistently below European average. The objective of this study was to examine recent survival trends in Estonia and to quantify the effect on survival estimates of the temporary disruption of the Estonian Cancer Registry (ECR) practices in 2001-2007 when death certificates could not be used for case ascertainment. PATIENTS AND METHODS: ECR data on all adult cases of 16 common cancers diagnosed in Estonia during 1995-2008 and followed up for vital status until 2009 were used to estimate relative survival ratios (RSR). We used cohort analysis for patients diagnosed in 1995-1999 and 2000-2004; and period hybrid approach to obtain the most recent estimates (2005-2009). We compared five-year RSRs calculated from data sets with and without death certificate initiated (DCI) cases. RESULTS: A total of 64328 cancer cases were included in survival analysis. Compared with 1995-1999, five-year age-standardized RSR increased 20 percent units for prostate cancer, reaching 76% in 2005-2009. A rise of 10 percent units or more was also seen for non-Hodgkin lymphoma (five-year RSR 51% in 2005-2009), and cancers of rectum (49%), breast (73%) and ovary (37%). The effect of including/excluding DCI cases from survival analysis was small except for lung and pancreatic cancers. CONCLUSIONS: Relative survival continued to increase in Estonia during the first decade of the 21st century, although for many cancers, a gap between Estonia and more affluent countries still exists. Cancer control efforts should aim at the reduction of risk factors amenable to primary prevention, but also at the improvement of early diagnosis and ensuring timely and optimal care to all cancer patients.

Determinants of risk factors of atherosclerosis in the postinfarction period: the Tallinn MI study.

Environmental as well as genetic factors are involved in the pathogenesis of myocardial infarction. The disease is a frequent cause of mortality in the middle-aged male population of Estonia. The high prevalence of premature myocardial infarction (PMI) in this country is not fully understood. The association of atherogenic and thrombogenetic risk factors with lifestyle was evaluated in men who had suffered myocardial infarction at 55 years of age (n = 71) and in randomly selected corresponding controls (n = 85). Serum routine lipids, apolipoprotein (apo)A-I, apoB, apoE polymorphism, lipoprotein(a) and fibrinogen levels were determined. Behavioural risk factors, indices of obesity, blood pressure and pedigree data were registered. In 80.6 % of PMI subjects some type of hyperlipidaemia was observed (European Atherosclerosis Society Classification) and lipid-lowering drugs were taken by 13.9 % of patients. In PMI patients the most common positive determinants of atherogenic lipoprotein indices were waist-to-hip ratio and physical inactivity, and in controls, waist-to-hip ratio and apoE phenotype. The odds ratio (OR) of PMI was 8.9-fold greater in the highest tertile of apoB/apoA-I distribution compared with the lowest tertile. The OR of PMI in the highest tertile of fibrinogen distribution versus the lowest tertile was 6.2 (95 % CI 2.46-15.44), and OR of PMI in the highest Lp(a) tertile versus the lowest was 3.1 (95 % CI 1.31-7.40). Thus, atherogenic dyslipidaemia was the most serious cardiovascular risk factor among PMI patients. From two thrombogenesis-related markers, the levels of fibrinogen and Lp(a), the first one was more strongly associated with PMI status.

The association between hyperglycaemia on admission and 180-day mortality in acute myocardial infarction patients with and without diabetes.

AIM: To evaluate the association between hyperglycaemia on admission, previously known diabetes and 180-day mortality in acute myocardial infarction (AMI) patients. METHODS: The study population consisted of 779 consecutive AMI patients from the Myocardial Infarction Registry in Estonia who had an admission venous plasma glucose level recorded and who were admitted to the Tartu University Clinics within a period of 2 years. Logistic regression analysis was used to estimate crude and adjusted odds ratios (OR) with 95% confidence interval (95% CI). RESULTS: In patients without a history of diabetes, glucose level was < or = 11.0 mmol/l in 556 patients (group 1) and > 11.0 mmol/l in 109 patients (group 2). Of those with diabetes, glucose level was < or = 11.0 mmol/l in 30 patients (group 3) and > 11.0 mmol/l in 84 patients (group 4). Non-diabetic hyperglycaemic patients underwent more resuscitations outside of hospital (group 2, 31.2% vs. group 1, 2.0% vs. group 3, 6.7% vs. group 4, 6.0%, P < 0.0001) and had a higher 180-day mortality compared with other groups (group 2, 47.7% vs. group 1, 14.1% vs. group 3, 26. 7% vs. group 4, 29.8%, P < 0.0001). After adjustment for potentially confounding factors, hyperglycaemic non-diabetic (OR 4.35, 95% CI 1.79-10.59), but not diabetic (OR 1.79, 95% CI 0.62-5.15) status, remained an independent predictor of 180-day mortality. CONCLUSIONS: AMI patients with hyperglycaemia on admission, independent of a history of diabetes, represent a high-risk population for 180-day mortality. The worst outcome occurs in non-diabetic hyperglycaemic patients. Further studies are warranted to clarify the questions of hyperglycaemia treatment in AMI patients.

Bladder cancer in Estonia, 1968-1992: incidence, mortality, prevalence and survival.

This paper summarizes what is known about the occurrence and survival of bladder cancer in Estonia from 1968 to 1992. In 1988-92 the age standardized (world standard) incidence rate of bladder cancer was 11.1 per 100,000 person-years in males and 2.0 in females, and the age standardized mortality rate was 8.2 and 2.7, respectively; by July 1, 1990 the age standardized prevalence rate was 41.5 and 14.7, respectively. Between 1968-72 and 1988-92, incidence increased by 1.26 times (95% confidence interval 1.09 to 1.46) among males; incidence rates for females did not show a consistent trend. The time trends in mortality generally paralleled the trends in incidence. Higher rates of bladder cancer were found among males in five large towns. For patients diagnosed in 1983-87, the five-year relative survival was 32.4% (95% confidence interval 27.0 to 37.8) for males and 32.5% (23.8 to 41.2) for females; throughout the 20 years there was no improvement in survival. As the survival rates are less favorable than those in the Nordic countries, further hospital-based studies are needed to investigate the relation between survival and clinical characteristics.
