Sociodemographic inequalities in mortality from drowning in the Baltic countries and Finland in 2000-2015: a register-based study.

BACKGROUND: Drowning is an important public health problem. Some evidence suggests that the risk of drowning is not distributed evenly across the general population. However, there has been comparatively little research on inequalities in drowning mortality. To address this deficit, this study examined trends and sociodemographic inequalities in mortality from unintentional drowning in the Baltic countries and Finland in 2000-2015. METHODS: Data for Estonia, Latvia and Lithuania came from longitudinal mortality follow-up studies of population censuses in 2000/2001 and 2011, while corresponding data for Finland were obtained from the longitudinal register-based population data file of Statistics Finland. Deaths from drowning (ICD-10 codes W65-W74) were obtained from national mortality registries. Information was also obtained on socioeconomic status (educational level) and urban-rural residence. Age-standardised mortality rates (ASMRs) per 100 000 person years and mortality rate ratios were calculated for adults aged 30-74 years old. Poisson regression analysis was performed to assess the independent effects of sex, urban-rural residence and education on drowning mortality. RESULTS: Drowning ASMRs were significantly higher in the Baltic countries than in Finland but declined by nearly 30% in all countries across the study period. There were large inequalities by sex, urban-rural residence and educational level in all countries during 2000-2015. Men, rural residents and low educated individuals had substantially higher drowning ASMRs compared to their counterparts. Absolute and relative inequalities were significantly larger in the Baltic countries than in Finland. Absolute inequalities in drowning mortality declined in all countries across the study period except between urban and rural residents in Finland. Changes in relative inequalities were more variable during 2000-2015. CONCLUSION: Despite a sharp reduction in deaths from drowning in the Baltic countries and Finland in 2000-2015, drowning mortality was still high in these countries at the end of the study period with a substantially larger risk of death seen among men, rural residents and low educated individuals. A concerted effort to prevent drowning mortality among those most at risk may reduce drownings considerably in the general population.

Educational inequalities in hypothermia mortality in the Baltic countries and Finland in 2000-15.

BACKGROUND: Despite an increased focus on cold-related mortality in recent years, there has been comparatively little research specifically on hypothermia mortality and its associated factors. METHODS: Educational inequalities in hypothermia mortality among individuals aged 30-74 in the Baltic countries (Estonia, Latvia, Lithuania) and Finland in 2000-15 were examined using data from longitudinal mortality follow-up studies of population censuses (the Baltics) and from a longitudinal register-based population data file (Finland). RESULTS: Age-standardized mortality rates (ASMRs) were much higher in the Baltic countries than in Finland across the study period. From 2000-07 to 2008-15, overall ASMRs declined in all countries except among Finnish women. Although a strong educational gradient was observed in hypothermia mortality in all countries in 2000-07, inequalities were larger in the Baltic countries. Between 2000-07 and 2008-15, ASMRs declined in all educational groups except for high-educated women in Finland and low-educated women in Lithuania; the changes however were not always statistically significant. The absolute mortality decline was often larger among the low educated resulting in narrowing absolute inequalities (excepting Lithuania), whereas a larger relative decline among the high educated (excepting Finnish women) resulted in a considerable widening of relative inequalities in hypothermia mortality by 2008-15. CONCLUSION: Although some reduction was observed in absolute educational inequalities in hypothermia mortality in 2000-15, substantial and widening relative inequalities highlight the need for further action in combatting factors behind deaths from excessive cold in socioeconomically disadvantaged groups, including risky alcohol consumption and homelessness.

Age, Period and Cohort Effects On Alcohol Consumption In Estonia, 1996-2018.

AIMS: To analyse the independent effects of age, period and cohort on estimated daily alcohol consumption in Estonia. METHODS: This study used data from nationally representative repeated cross-sectional surveys from 1996 to 2018 and included 11,717 men and 16,513 women aged 16-64 years in total. The dependent variables were consumption of total alcohol and consumption by types of beverages (beer, wine and strong liquor) presented as average daily consumption in grams of absolute alcohol. Mixed-effects negative binomial models stratified by sex were used for age-period-cohort analysis. RESULTS: Alcohol consumption was highest at ages 20-29 years for both men and women and declined in older ages. Significant period effects were found indicating that total alcohol consumption and consumption of different types of beverages had increased significantly since the 1990s for both men and women. Cohort trends differed for men and women. Men born in the 1990-2000s had significantly lower daily consumption compared to earlier cohorts, whereas the opposite was found for women. CONCLUSION: While age-related patterns of alcohol consumption are aligned with life course stages, alcohol use has increased over the study period. Although the total daily consumption among men is nearly four times higher than among women, the cohort trends suggest convergence of alcohol consumption patterns for men and women.

Childhood cancer incidence and survival trends in Estonia (1970-2016): a nationwide population-based study.

BACKGROUND: Childhood cancers represent a small proportion of all cancers but are still a major public health problem. The study analysed long-term trends in childhood cancer incidence and survival in Estonia in relation to societal and health care transition. METHODS: Data on all malignant tumours, diagnosed in children aged 0-14 during 1970-2016, were derived from the Estonian Cancer Registry. Age-standardised (World standard) incidence rates were calculated by ICCC-3 site groups and joinpoint regression was used to estimate annual percentage change (APC) for incidence trends. Cohort and period approach were used to estimate 5-year survival. Internal age standardisation was applied. RESULTS: A total of 1628 incident cancer cases were diagnosed during the study period and overall incidence increased significantly at a rate of 0.5% per year. Significant increases were seen for neuroblastoma and germ cell tumours, for lymphoid leukemias and some CNS sub-sites. At the same time, decline in incidence was seen in almost all subgroups of unspecified neoplasms. The overall 5-year survival improved from 24% in 1970-1979 to 73% in 2010-2016, with the largest changes occurring in the 1990s and 2000s. For many sites, survival increase thereafter has been marginal. CONCLUSION: In this first comprehensive population-based study of childhood cancer incidence and survival in Estonia, long-term trends are shown in the context of societal and health care changes. Even though the increasing incidence of some sites may, at least partially, be explained by improved diagnostics reflected in the decreased incidence of unspecified neoplasms, the overall cancer incidence in children seems to be rising. Rapid progress in diagnosis and care have improved childhood cancer survival immensely, but deficit in Estonia persists compared to other European countries. Results of the study accentuate the need for a more in-depth analysis of clinical data, but also for the prioritization of childhood cancer in Estonia, to ensure access to standard care and innovative treatments.

Increasing kidney cancer incidence and survival in Estonia: role of age and stage.

BACKGROUND: Kidney cancer rates in Estonia are high. The study aimed to examine long-term trends in kidney cancer incidence, mortality and survival in Estonia, with special focus on age, birth cohorts, morphology and TNM stage. MATERIAL AND METHODS: Estonian Cancer Registry provided data on all incident cases of kidney cancer (ICD-10 C64), diagnosed in adults (age ≥15 years) in Estonia during 1995 - 2014. Relative survival ratios (RSR) were calculated and excess hazard ratios of dying were estimated with gender, age, period of diagnosis and TNM stage as independent variables. Joinpoint regression modeling was used to calculate estimated annual percentage change for incidence (1970-2014) and mortality (1995-2016) trends. Age-specific incidence rates were presented by birth cohort and period of diagnosis. RESULTS: Incidence increased significantly in both sexes, with the steepest rise seen for localized cancer. Cohort effects were pronounced particularly in men, while period effects were seen from the mid-1980s to mid-1990s in both sexes. Age-standardized five-year RSR for total kidney cancer increased by 13 percentage units (from 53% to 65%) over the study period; the increase was larger for renal cell carcinoma (from 63% to 78%). Survival increases of about five percentage units were seen for stages I/II and III. Age and gender were not associated with excess risk of dying from renal cell carcinoma after adjusting for stage. CONCLUSION: Estonia is currently among countries with the highest incidence of kidney cancer. The results suggest a combined effect of changing risk profiles in successive birth cohorts and increasing diagnostic activity around 1990. Large survival increase can mostly be attributed to earlier detection, but improved diagnosis and treatment have probably influenced stage-specific survival. High proportion of tumors with unspecified morphology and those with unknown stage among the elderly warrants further investigation of diagnostic and treatment practices.

Gastric cancer trends in Estonia 1995-2014 by age, subsite, morphology and stage.

BACKGROUND: Gastric cancer (GC) is among the most common cancers and one of the leading causes of cancer deaths globally. In general, the incidence of GC has declined and survival improved in Europe. Nevertheless, previous analysis has shown that survival of GC patients in Estonia is still significantly lower compared to some European countries. Therefore, to improve patient outcomes, better overview of GC epidemiology is needed. The aim of this study was to describe the incidence and survival of GC in Estonia 1995-2014 in relation to age, subsite, morphology, and the extent of disease. MATERIAL AND METHODS: We used data from the population-based Estonian Cancer Registry on all incident cases of GC diagnosed in 1995-2014. Incidence rates and relative survival were calculated. Joinpoint regression modeling was used to estimate annual percentage change for incidence trends. Data were analyzed by age, sex, subsite, morphology, and the extent of disease. Changes between 1995-1999 and 2010-2014 were assessed. RESULTS: The overall incidence of GC in Estonia decreased in 1995-2014. The age-standardized (world) incidence declined significantly for both sexes, for patients below 70 years of age, adenocarcinomas, NOS and other morphologies, non-cardia and unspecified cases, and for all known stages. Approximately 40% of GC cases were diagnosed with distant metastasis. Overall age-standardized 5-year relative survival of GC patients increased from 20% to 28%. Survival improved the most in age group 50-69 years. A large survival gain was also seen for localized (from 55% to 70%) and locally/regionally spread disease (from 23% to 37%). CONCLUSIONS: In Estonia, the incidence of GC has declined and relative survival increased. However, special emphasis needs to be put on improving survival among men, elderly and in patients with metastatic disease.

Trends in cervical cancer incidence and survival in Estonia from 1995 to 2014.

BACKGROUND: Cervical cancer (CC) incidence in Estonia is the third highest in Europe, even though an organised nation-wide screening program has been in place since 2006. The aim of the study was to analyse the incidence and survival of CC in Estonia, focusing on age, morphology and stage at diagnosis. METHODS: Data from Estonian Cancer Registry were used to analyse age-standardized (world) and age-specific incidence for 1968-2014 rates. Joinpoint regression was used to estimate the annual percentage change (APC) for incidence trends. Age-period-cohort model was used to summarise time trends in terms of cohort and period effects. Relative survival ratios (RSR) were calculated for cases diagnosed in 1995-2014. Union for International Cancer Control version 7 of the TNM classification for malignant tumours was used to categorise stage. RESULTS: The age-standardized incidence of CC increased since 1980s at a rate of 0.8% per year. A significant increase was seen for all age groups except for 70+. The incidence of squamous cell carcinoma mimicked the overall trend, while adenocarcinoma showed increase since mid-1990s (APC 6.7). Age-period-cohort modelling showed strong cohort effects with the lowest risk for birth-cohorts born around 1940 and significantly increasing risks for successive cohorts born thereafter. No period effects were seen. The proportion of stage IV cases increased from 13% in 2005-2009 to 18% in 2010-2014. A significant increase was seen in the overall 5-year RSR from 1995 to 1999 to 2010-2014 (58% vs 66%). In 2010-2014, the 5-year RSRs ranged from 89% in women aged 15-39 to 41% in age group 70+. For stages I to IV, the respective RSRs were 98, 74, 57 and 22%. CONCLUSIONS: The inadequate uptake and insufficient quality of the Pap-smear based screening program has not brought along a decline in the incidence of CC in Estonia. Stage distribution has shifted towards later stages. New approaches are needed to prevent CC in Estonia.

Divergent trends in lung cancer incidence by gender, age and histological type in Estonia: a nationwide population-based study.

BACKGROUND: Lung cancer (LC) is the leading cause of cancer deaths in men and the second most frequent cause of cancer deaths in women in Estonia. The study aimed to analyze time trends in LC incidence and mortality in Estonia over the 30-year period, which included major social, economic and health care transition. The results are discussed in the context of changes in tobacco control and smoking prevalence. Long-term predictions of incidence and mortality are provided. METHODS: Data for calculating the incidence and mortality rates in 1985-2014 were obtained from the nationwide population-based Estonian Cancer Registry and the Causes of Death Registry. Joinpoint regression was used to analyze trends and estimate annual percentage change (APC) with 95% confidence interval (CI). Nordpred model was used to project future incidence and mortality trends for 2015-2034. RESULTS: Incidence peaked among men in 1991 and decreased thereafter (APC: -1.5, 95% CI: -1.8; -1.3). A decline was seen for all age groups, except age ≥ 75 years, and for all histological types, except adenocarcinoma and large cell carcinoma. Incidence among women increased overall (APC: 1.6, 95% CI: 1.1; 2.0) and in all age groups and histological types, except small cell carcinoma. Age-standardized incidence rate (world) per 100,000 was 54.2 in men and 12.9 in women in 2014. Changes in mortality closely followed those in incidence. According to our predictions, the age-standardized incidence and mortality rates will continue to decrease in men and reach a plateau in women. CONCLUSIONS: The study revealed divergent LC trends by gender, age and histological type, which were generally consistent with main international findings. Growing public awareness and stricter tobacco control have stimulated overall favorable changes in men, but not yet in women. Large increase in incidence was observed for adenocarcinoma, which in men showed a trend opposite to the overall decline. LC will remain a serious public health issue in Estonia due to a high number of cases during the next decades, related to aging population, and previous and current smoking patterns. National tobacco control policy in Estonia should prioritize preventing smoking initiation and promoting smoking cessation, particularly among women.

Trends in incidence and survival of cutaneous malignant melanoma in Estonia: a population-based study.

BACKGROUND: Previous studies have shown an increase in the incidence of cutaneous melanoma (CM) in Estonia, but also poor survival in international comparisons, with a significant survival gap between the sexes. The aim of this study was to analyze the time trends in CM incidence and relative survival by age, TNM stage and anatomical subsite among men and women in Estonia. MATERIALS AND METHODS: Data from the Estonian Cancer Registry were used to calculate age-standardized (World) and age-specific incidence of CM in 1995-2013, and five-year relative survival ratios (RSR) for cases diagnosed in 1995-2012 and followed through in 2014. Period hybrid analysis was used to calculate the most recent survival estimates for 2010-2014. RESULTS: Between 1995 and 2013, the age-standardized incidence of CM increased significantly in Estonia among both sexes, at a rate of around 4% per year. Among women, the proportion of trunk melanomas increased from 26% in 1995-1999 to 39% in 2010-2012 and became the most common site. The proportion of stage I cases and T1 tumors increased considerably. Women had more favorable stage distribution and thinner tumors than men. The age-adjusted five-year RSR increased significantly, from 64% in 1995-1999 to 81% in 2010-2014. The latest age-adjusted RSRs were 76% among men and 84% among women. Survival gains were the largest in patients below 50 years, those with head and neck or trunk melanomas, and stage III cancer. CONCLUSIONS: The proportion of stage I and T1 cases is lower in Estonia compared with the Scandinavian data and is likely a major contributor to the persisting overall survival deficit in Estonia. The apparent deficit in stage II survival also warrants further investigation. A public health program is necessary in Estonia to raise awareness of CM and to significantly increase early stage diagnosis.

Time Trends in Ovarian Cancer Survival in Estonia by Age and Stage.

OBJECTIVE: The objective of the study was to examine temporal trends in ovarian cancer (OC) survival in Estonia during 1995 to 2009 in relation to age and stage. MATERIALS AND METHODS: Estonian Cancer Registry data on all adult cases of primary OC diagnosed during 1995 to 2009 and followed up for vital status until 2014 were used to estimate relative survival ratios (RSRs). Cohort analysis was used to estimate 1-, 2-, and 5-year RSRs for patients diagnosed in 1995 to 1999, 2000 to 2004, and 2005 to 2009. Analysis was performed by age at diagnosis (<50; 50-59; 60-69; 70+ years) and stage (International Federation of Gynecology and Obstetrics 1988). RESULTS: Among 2296 women included in the study, the age-adjusted 5-year RSR improved from 27% in 1995 to 1999 to 38% in 2005 to 2009. Survival increase of 10% units from 1995 to 1999 to 2005 to 2009 was seen for women aged 50 to 59 and 60 to 69 years. Among younger and older women, the respective changes were smaller. In 1995 to 1999, the difference in survival between the youngest and oldest age groups was 41% units. This decreased over the study period to 37% units. From 1995 to 1999 to 2005 to 2009, the 5-year RSR increased from 82% to 91% for stage I patients; from 48% to 67% for stage II patients; from 25% to 35% for stage III patients; and from 11% to 16% for stage IV patients. CONCLUSIONS: The study showed an improvement of OC survival in Estonia in all age and stage groups, but particularly among younger women and those with early stage disease. Slower progress among older women is of great concern.

Age, period and cohort effects on suicide mortality in Russia, 1956-2005.

BACKGROUND: Russian suicide mortality rates changed rapidly over the second half of the twentieth century. This study attempts to differentiate between underlying period and cohort effects in relation to the changes in suicide mortality in Russia between 1956 and 2005. METHODS: Sex- and age-specific suicide mortality data were analyzed using an age-period-cohort (APC) approach. Descriptive analyses and APC modeling with log-linear Poisson regression were performed. RESULTS: Strong period effects were observed for the years during and after Gorbachev's political reforms (including the anti-alcohol campaign) and for those following the break-up of the Soviet Union. After mutual adjustment, the cohort- and period-specific relative risk estimates for suicide revealed differing underlying processes. While the estimated period effects had an overall positive trend, cohort-specific developments indicated a positive trend for the male cohorts born between 1891 and 1931 and for the female cohorts born between 1891 and 1911, but a negative trend for subsequent cohorts. CONCLUSIONS: Our results indicate that the specific life experiences of cohorts may be important for variations in suicide mortality across time, in addition to more immediate effects of changes in the social environment.

Recent changes in breast cancer incidence and mortality in Estonia: Transition to the west.

Background The aim of this study was to examine breast cancer (BC) incidence and mortality trends in Estonia during recent decades and to compare the pattern of these trends with other selected European countries and regions. We attempt to explain the findings in relation to changes in Estonian society and healthcare system. Methods BC incidence (1985-2012) and mortality (1985-2013) data for Estonia were obtained from the Estonian Cancer Registry and Statistics Estonia. Data for selected European countries were obtained from the EUREG database. Joinpoint regression was used to analyze age-standardized rates in Estonia by age. For international comparison of incidence and mortality rates, we used scatterplot with 95% confidence ellipses and the mortality to incidence ratio. Results The overall BC incidence continues to increase in Estonia, while mortality has been in decline since 2000. Both incidence and mortality trends varied considerably across age groups. Among women aged 60 years and older, BC incidence increased at a rate of nearly 3% per year. Significant decrease in mortality was seen only among women aged 50-59 years. Comparison of scatterplots between countries and regions revealed two clusters in Europe separated along the incidence axis. The correlation between incidence and mortality in Estonia changed its direction in the mid-1990s. Conclusion In recent years, the dynamics of BC burden in Estonia has transitioned towards the high incidence-low mortality type model, which is characteristic to Western, Northern and Southern Europe. Although overall BC incidence is much lower in Estonia than in more affluent European countries, mortality from BC is still relatively high, particularly among elderly women.

Time trends in population-based breast cancer survival in Estonia: analysis by age and stage.

BACKGROUND: Survival from breast cancer (BC) in Estonia has been consistently among the lowest in Europe. The aim of this study was to examine most recent trends in BC survival in Estonia by age and stage. The trends in overall BC incidence and mortality are also shown in the paper. MATERIAL AND METHODS: Estonian Cancer Registry data on all cases of BC, diagnosed in women in Estonia during 1995-2007 (n = 7424) and followed up for vital status through 2009, were used to estimate relative survival ratios (RSR). Period hybrid approach was used to obtain the most recent estimates (2005-2009). Stage was classified as localized, local/regional spread or distant. RESULTS: BC incidence continued to rise throughout the study period, but mortality has been in steady decline since 2000. The distribution of patients shifted towards older age and earlier stage at diagnosis. Overall age-standardized five-year RSR increased from 63% in 1995-1999 to 74% in 2005-2009. Younger age groups experienced a more rapid improvement compared to women over 60. Significant survival increase was observed for both localized and locally/regionally spread BC with five-year RSRs reaching 96% and 70% in 2005-2009, respectively; the latest five-year RSR for distant BC was 11%. Survival for T4 tumors was poor and large age difference was seen for locally/regionally spread BC. CONCLUSIONS: Considerable improvement in BC survival was observed over the study period. Women under 60 benefited most from both earlier diagnosis and treatment advances of locally/regionally spread cancers. However, the survival gap with more developed countries persists. Further increase in survival, but also decline in BC mortality in Estonia could be achieved by facilitating early diagnosis in all age groups, but particularly among women over 60. Investigations should continue to clarify the underlying mechanisms of the stage-specific survival deficit in Estonia.

Sex-specific outcomes of diabetic patients with acute myocardial infarction who have undergone percutaneous coronary intervention: a register linkage study.

BACKGROUND: The presence of diabetes mellitus poses a challenge in the treatment of patients with acute myocardial infarction (AMI). We aimed to evaluate the sex-specific outcomes of diabetic and non-diabetic patients with AMI who have undergone percutaneous coronary intervention (PCI). METHODS: Data of the Estonian Myocardial Infarction Registry for years 2006-2009 were linked with the Health Insurance Fund database and the Population Registry. Hazard ratios (HRs) with the 95% confidence intervals (CIs) for the primary composite outcome (non-fatal AMI, revascularization, or death whichever occurred first) and for the secondary outcome (all cause mortality) were calculated comparing diabetic with non-diabetic patients by sex. RESULTS: In the final study population (n=1652), 14.6% of the men and 24.0% of the women had diabetes. Overall, the diabetics had higher rates of cardiovascular risk factors, co-morbidities, and 3-4 vessel disease among both men and women (p<0.01). Among women, the diabetic patients were younger, they presented later and less often with typical symptoms of chest pain than the non-diabetics (p<0.01). Women with diabetes received aspirin and reperfusion for ST-segment elevation AMI less often than those without diabetes (p<0.01). During a follow-up of over two years, in multivariate analysis, diabetes was associated with worse outcomes only in women: the adjusted HR for the primary outcome 1.44 (95% CI 1.05-1.96) and for the secondary outcome 1.83 (95% CI 1.17-2.89). These results were largely driven by a high (12.0%) mortality during hospitalization of diabetic women. CONCLUSIONS: Diabetic women with AMI who have undergone PCI are a high-risk group warranting special attention in treatment strategies, especially during hospitalization. There is a need to improve the expertise to detect AMI earlier, decrease disparities in management, and find targeted PCI strategies with adjunctive antithrombotic regimes in women with diabetes.

Short-term postoperative changes in temporomandibular joints and masticatory muscles of Angle class II patients after mandibular advancement surgery: Clinical findings.

BACKGROUND AND OBJECTIVE: The aim of the study was to detect postoperative changes in the temporomandibular joints (TMJs) and masticatory muscles of Angle class II malocclusion patients who underwent mandibular advancement surgery. MATERIAL AND METHODS: Twenty-three patients were selected for mandibular advancement by bilateral sagittal split ramus osteotomy (BSSO). Cephalograms and clinical evaluation were performed before the surgery as well as fourteen days and six months after surgery. Clinical examination included measurement of overjet, overbite and of the amplitude of mandibular movements, registration of deviation on mouth opening, of TMJ pain and pathological sounds and of tenderness of masticatory muscles on palpation. Mandibular position was determined by cephalometric analysis. Statistical analyses were performed using a mixed-level longitudinal random intercept model with a confidence level of 95% and a P-value of 0.05 to reveal significant differences. RESULTS: Statistical results showed a mean mandibular advancement of 4 mm (3.1-5.0). Cephalometric measurements, overjet and overbite remained stable six months after surgery. Postoperative amplitude of mandibular movements was limited and did not completely recover 6 months later. Mouth opening was the most affected, showing an average reduction of 7.5 mm six months after surgery. Deviation on mouth opening, pathological TMJ sounds, TMJ pain and masticatory muscle tenderness did not show significant changes. CONCLUSIONS: Moderate mandibular advancement surgery offers stable results, yet the amplitudes of mandibular movements, were significant smaller after surgery and did not completely recovered 6 months following surgery. TMJ and masticatory muscles symptoms did not change after the surgery, suggesting that mandibular advancement surgery does not change the course of TMD.

Educational inequalities in epilepsy mortality in the Baltic countries and Finland in 2000-2015.

Little is known about socioeconomic differences in epilepsy mortality. This study examined educational inequalities in epilepsy mortality in the general population in the Baltic countries and Finland in 2000-2015. Education-specific mortality estimates for individuals aged 30-74 in Estonia, Latvia and Lithuania were obtained from census-linked mortality datasets while data for Finland came from the register-based population and death data file of Statistics Finland. Trends and educational inequalities in epilepsy mortality were assessed using age-standardised mortality rates (ASMRs) per 100,000 person years and age-adjusted mortality rate ratios (RRs) calculated using Poisson regression. ASMRs were higher in men than women in all countries. ASMRs reduced in 2000-2015 among all men and women except for Finnish women. Among men, an inverse educational gradient in epilepsy mortality in 2000-2007 widened in 2008-2015 with ASMRs falling among high and mid educated men in all countries but increasing among low educated men in three countries. An inverse educational gradient in female mortality remained in all countries throughout 2000-2015. Although epilepsy mortality fell in the Baltic countries and Finland (men only) in 2000-2015, this masked a clear inverse educational gradient in mortality that became steeper across the period.

Incidence and Survival for Head and Neck Cancers in Estonia, 1996-2016: A Population-Based Study.

BACKGROUND: Changing patterns of alcohol and tobacco consumption and human papillomavirus (HPV) infection have affected the epidemiology of head and neck cancers. The aim of this study was to examine 20-year trends in the incidence and survival of head and neck cancers in Estonia by site, sex, morphology, and stage. METHODS: Data on all adult cases of invasive head and neck cancers diagnosed in Estonia in 1996-2016 were obtained from a population-based cancer registry. TNM stage was available for 2010-2016. Incidence trends were modeled with join-point regression, and five-year relative survival ratios (RSRs) were calculated. RESULTS: A total of 6,769 cases were included, 64% men. We observed declining incidence of lip and laryngeal cancer and substantial increases in the incidence of hypopharyngeal and oropharyngeal cancers. Over 60% of mouth and pharyngeal cancers were diagnosed at stage IV. Age-standardized 5-year RSR for mouth and pharyngeal cancer increased substantially over the study period, from 21% (95% CI 16%-25%) in 1996-2002 to 33% (29%-38%) in 2010-2016. The largest survival increases were seen for cancers of the oral cavity (reaching 44% in 2010-2016), tongue (41%), and larynx (63%), while modest changes were seen for the oropharynx (24%) and hypopharynx (17%). The latest 5-year RSR was 90% for thyroid cancers (99% for papillary carcinoma). Large female survival advantage was seen for most sites. CONCLUSION: The observed trends suggest an emerging role of HPV infection in combination with traditional risk factors in the development of head and neck cancers in Estonia. Efforts targeting health behavior, HPV vaccination, and earlier diagnosis are crucial for reducing mortality from these cancers.

Macroeconomic changes and educational inequalities in traffic fatalities in the Baltic countries and Finland in 2000-2015: a register-based study.

This study examined trends and inequalities in road traffic accident (RTA) mortality in the Baltic countries (Estonia, Latvia, Lithuania) and Finland in relation to large-scale macroeconomic changes in the 2000s. Educational inequalities in RTA mortality in 2000-2003, 2004-2007, 2008-2011 and 2012-2015 among 30-74 year olds were examined using census-linked longitudinal mortality data and by estimating the relative and slope index of inequality. Overall RTA mortality decreased substantially between 2000-2003 and 2012-2015. From 2004-2007 to 2008-2011, the RTA mortality decline accelerated but was larger in the Baltic countries. Among men the RTA mortality decline was mostly driven by a larger fall among the high and middle educated. Among women, the changes in RTA mortality by educational level had no clear pattern. From 2000-2003 to 2012-2015 relative educational inequalities in RTA mortality increased among men, although more in the Baltic countries. Among women the pattern was mixed across countries. Absolute inequalities fell in all countries among both sexes. Educational inequalities in male RTA mortality may be growing because of increasingly less access to safer cars and a more hazardous driving culture among the lower educated.

Economic cycles and inequalities in alcohol-related mortality in the Baltic countries and Finland in 2000-2015: a register-based study.

AIM: To estimate whether large macroeconomic fluctuations in the 2000s affected inequalities in alcohol-related mortality in the Baltic countries and Finland. DESIGN: Longitudinal register-based follow-up study. SETTING: Estonia, Latvia, Lithuania and Finland. PARTICIPANTS: General population in the 35-74 age group. MEASUREMENTS: Socioeconomic status was measured by the highest achieved educational level and was categorised using the International Standard Classification of Education 2011 as low (included categories 0-2), middle (3-4), and high (5-8). Educational inequalities in alcohol-related mortality in 2000-2003, 2004-2007, 2008-2011 and 2012-2015 were examined using census-linked longitudinal mortality data. We estimated age-standardised mortality rates and the relative and slope index of inequality. FINDINGS: Alcohol-related mortality increased in all countries in 2004-2007 except among Estonian women and decreased/remained the same from 2008 onward except among Latvian men. By 2012-2015 alcohol-related mortality was still higher than in 2000-2003 in Finland, Latvia and Lithuania (women only). Relative inequalities increased across the study period in all countries (significantly in Lithuania and Latvia). The 2004-2007 increase in relative inequalities was mostly driven by a larger mortality increase among the low educated, whereas in 2008-2011 and in 2012-2015 inequalities often increased because of a larger relative mortality decline among the high educated. However, these period changes in relative inequalities and between educational groups were often not statistically significant. Absolute inequalities were larger in 2012-2015 versus 2000-2003 in all countries except Estonia (decrease). CONCLUSION: In the Baltic countries and Finland, alcohol-related mortality tended to increase faster among the low educated during a period of economic expansion (2004-2007) and decrease more among the high educated during a period of economic recession (2008-2011).

Use of evidence-based pharmacotherapy after myocardial infarction in Estonia.

BACKGROUND: Mortality from cardiovascular disease in Estonia is among the highest in Europe. The reasons for this have not been clearly explained. Also, there are no studies available examining outpatient drug utilization patterns in patients who suffered from acute myocardial infarction (AMI) in Estonia. The objective of the present study was to examine drug utilization in different age and gender groups following AMI in Estonia. METHODS: Patients admitted to hospital with AMI (ICD code I21-I22) during the period of 01.01.2004-31.12.2005 and who survived more than 30 days were followed 365 days from the index episode. Data about reimbursed prescriptions of beta-blockers (BBs), angiotensin converting enzyme inhibitors/angiotensin II receptor blockers (ACE/ARBs) and statins for these patients was obtained from the database of the Estonian Health Insurance Fund. Data were mainly analysed using frequency tables and, where appropriate, the Pearson's chi2 test, the Mann-Whitney U-test and the t-test were used. A logistic regression method was used to investigate the relationship between drug allocation and age and gender. We presented drug utilization data as defined daily dosages (DDD) per life day in four age groups and described proportions of different combinations used in men and women. RESULTS: Four thousand nine hundred patients were hospitalized due to AMI and 3854 of them (78.7%) were treated by BBs, ACE/ARBs and/or statins. Of the 4025 inpatients who survived more than 30 days, 3799 (94.4%) were treated at least by the one of drug groups studied. Median daily dosages differed significantly between men and women in the age group 60-79 years for BBs and ACE/ARBs, respectively. Various combinations of the drugs studied were not allocated in equal proportions for men and women, although the same combinations were the most frequently used for both genders. The logistic regression analysis adjusted to gender and age revealed that some combinations of drugs were not allocated similarly in different age and gender groups. CONCLUSIONS: Most of the patients were prescribed at least one of commonly recommended drugs. Only 40% of them were treated by combinations of beta-blockers, ACE inhibitors/angiotensin II receptor blockers and statins, which is inconsistent with guideline recommendations in Estonia. Standards of training and quality programs in Estonia should be reviewed and updated aiming to improve an adherence to guidelines of management of acute myocardial infarction in all age and gender groups.
