Is the prevalence of atopic diseases in East and West Germany already converging?

Studies comparing respiratory health of residents in the areas of former East and West Germany have shown higher rates of asthma and allergies in children and young adults in former West Germany. It has been speculated that some factors associated with western lifestyle may be related to higher rates of atopic diseases among residents of former West Germany. We examined if the prevalence rates of self-reported asthma and nasal allergies in adults converged between the areas of former East and West Germany five years after re-unification. During the years 1990–1992 and 1994–1995 two independently drawn random samples of more than 3,000 subjects between the ages of 20 to 44 years answered a screening questionnaire of the European Community Respiratory Health Survey in Erfurt (East Germany) and in Hamburg (West Germany). The prevalence rates of asthma attacks, asthma medication use, allergic rhinitis, and wheezing remained stable in Hamburg but increased significantly in Erfurt approaching those of Hamburg. The data indicate that there is a tendency for the prevalence rates of self-reported allergic rhinitis and asthma-related respiratory symptoms in the eastern part of Germany to increase to West-German levels. It is not yet clear if this is due to a true increase in morbidity or only to a higher awareness for these diseases among doctors and the public.     

Airway diseases and allergies in East and West German children during the first 5 years after reunification: time trends and the impact of sulphur dioxide and total suspended particles

BACKGROUND: East-West comparison studies in Europe find higher prevalences of infectious airway diseases and lower prevalences of allergies in eastern areas. Pollution from sulphur dioxide (SO2) or total suspended particles (TSP) are discussed as causes of this difference. METHODS: In four differently polluted areas of East Germany where pollution decreased dramatically between 1989 and 1995 cross-sectional studies in about 7-year-old children were repeated every year between 1991 and 1995. In two differently polluted areas of West Germany studies with the same design were done in 1991 and 1994. In all, 19090 children participated in the study. Thirteen different questions about airway diseases and allergies were evaluated. Logistic regression was used to adjust for confounding. RESULTS: With the exception of pneumonia, all infectious airway diseases and irritations of the airways show a steeper temporal decrease in East than in West Germany or are positively associated with either SO2 or TSP in East Germany. For allergies and related symptoms no differences in time trends could be detected or no association with SO2 or TSP could be seen in East Germany. CONCLUSION: Most airway diseases were more frequent in East than in West Germany in 1991 and were associated with SO2 or TSP. The decrease in these pollutants between 1991 and 1995 has already had a favourable effect. An effect of SO2 or TSP pollution on allergies and related symptoms could not be detected. This pollution does not protect against the development of allergies.     

Comparison of risk factors for coronary heart disease in Dresden and Münster

Trend analyses based on WHO statistics for average life expectancy, age-standardized cardiovascular (CVD) morbidity and mortality show significant differences between the former German Democratic Republic (GDR) and the former Federal Republic of Germany (FRG). To investigate whether this is due to a different prevalence of cardiovascular risk factors, the Dresden Cardiovascular Risk and Nutrition (DRECAN) study was conducted using the complete methodology of the Prospective Cardiovascular Münster (PROCAM) study, i.e., the same methods and strict quality controls, with an exchange of specimens between both laboratories. The results were compared with those of an adjusted subpopulation of the PROCAM study.Even before unification there were only small differences in lipoprotein profiles between West and East Germany, 10 months after unification these differences were minimal. The survey does not sufficiently explain the differences in CHD morbidity and mortality between Western and Eastern Germany. Further analyses of the nutritional aspects will show whether the change, in available foodstuffs after unification has led to substantially changed nutritional habits, and whether this might explain some of the results.

Lebenserwartung, vorzeitig verlorene Lebensjahre und vermeidbare Sterblichkeit im Ost-West-Vergleich

The dynamics of convergence between East and West Germany in the life-prolonging process continued undiminished from 1990 until 2001. The regional differences in premature and avoidable mortality were clearly reduced, both between East and West and between the individual federal states. In the East and in the West there was an increase in life expectancy in all age groups and for both sexes, whereby the increase in life expectancy was considerably greater in East Germany and in all of the East German federal states. Also, the standardized potential years of life lost before the age of 65 decreased more intensively in East Germany. The women in East Germany achieved a lower premature mortality due to illness in the year 2001 than those in West Germany. In the initial year of 1990, the years of life lost were 27.2% greater. Unnatural premature mortality (especially due to accidents) was also relatively high in East Germany in the year 2001, but it is clearly being reduced. The avoidable mortality has been more than cut in half in all East German federal states since 1990. An almost complete alignment between East and West in regard to avoidable mortality was achieved in the year 2001. The phase of economic stagnation that can be observed in East Germany since 1997 has up to now not led to a worsening in the constitutive health references presented above.     

Comparison of health inequalities between East and West Germany

Background: The major objective of the study was to assess whetherthe extent of health inequalities varies between East and WestGermany and whether differences in social Inequalities betweenboth parts of Germany are associated with differences in healthinequalities. Methods: Data were available from a representativesample of 5,311 persons from West Germany and 2,414 personsfrom East Germany in the same age group (25–69 years).The study protocol was nearly identical in both studies. Socioeconomicstatus (SES) was assessed by household equivalent income andby educational level. Health status was assessed by perceivedgeneral health and by the number of chronic conditions. Absolutedifferences as well as relative differences (odds ratios) inthe morbidity rates between low and high SES groups were calculated.All analyses were performed separately for men and women. Results:Income inequalities are larger in West Germany as compared withEast Germany, but there are minor differences between East andWest Germany concerning educational inequalities and morbidityrates. Just about all measures indicated that health inequalitiesfavouring the upper socioeconomic groups exist in East Germanyas well as in West Germany and that there are no significantdifferences in the extent of health inequalities between bothparts of Germany. Conclusion: Using two data sets which wereraised with nearly identical study protocols, it can be concludedthat health inequalities are very stabile as they do not seemto differ substantially despite the fact that both parts ofGermany have experienced different social systems during thepast 45 years.     

AIDS – Wie leben schwule Männer heute? Kurzfassung der Ergebnisse der Befragung November 1999

A four page questionnaire was included in the November 1999 edition of 10 monthly German magazines for gay men to investigate how this population responds to risks posed by HIV/AIDS. This was the sixth time the questionnaire was administered in the former West Germany since 1987 and the fourth time in the former East Germany since 1991. A total of 2995 men responded (16% from the former East Germany, and 84% from the former West Germany). In 1999, 72% of respondents from both the western and eastern parts of the country did not engage in risk contacts in the twelve months preceding the survey, where risk contact was defined as unprotected anal intercourse with partners whose serostatus was unknown or whose status differed from that of the subject. In 1996, this percentage was 72% for East Germans and 76% for West Germans. The occurrence of protective behaviour in East and West has become increasingly similar over time; whereas, the proportion of men in the West German samle taking risks has increased since 1996. Whether the increased risk-taking in the West can be attributed to the introduction of combination therapy is a question which cannot be answered on the basis of the data gathered.     

Violence and fear of violence in East and West Germany

The purpose of this research was to assess the effect of major social changes in Germany since 1989 on mortality due to intentional injury. Mechanisms and types of fatal intentional injury in East and West Germany between 1970 and 1995 were determined from death certificates and compared with judicial data on violent crime convictions and recent public survey data on citizen fear of crime. The number of homicides among East German males increased between 1989 and 1991, and the homicide rate remains high when compared with West German males (although lower than that of American males). Homicide among German females is less common, presently about equally likely in East and West. Violent crime in general has become more frequent in Germany, and citizen fear of crime has increased markedly, especially in the East. Non-citizens are convicted for an increasing number of homicides and assaults. Rates of suicide were declining in East and West before reunification, and these rates have continued to decline. Social changes in Europe since 1989 have led to noticeable increases in violence and homicide in Germany, which in turn have reduced feelings of security among German citizens, especially in the East. Suicide rates have not been affected.     

Changing mortality patterns in East and West Germany and Poland. II: short-term trends during transition and in the 1990s

OBJECTIVES: To examine trends in life expectancy at birth and age and cause specific patterns of mortality in the former German Democratic Republic (GDR) and Poland during political transition and throughout the 1990s in both parts of Germany and in Poland. METHODS: Decomposition of life expectancy by age and cause of death. Changes in life expectancy during transition by cause of death were examined using data for 1988/89 and 1990/91 for the former GDR and Poland; examination of life expectancy changes after transition were based on 1992-97 data for Germany and 1991-96 data for Poland. RESULTS: In both the former GDR and Poland male life expectancy at birth declined by almost one year during transition, mainly attributable to rising death rates from external causes and circulatory diseases. Female life expectancy in Poland deteriorated by 0.3 years, largely attributable to increasing circulatory mortality among the old, while in East German female rising death rates in children and young adults were nearly outbalanced by declining circulatory mortality among those over 70. Between 1991/92 and 1996/97, male life expectancy at birth increased by 2.4 years in the former GDR, 1.2 years in old Federal Republic, and 2.0 years in Poland (women: 2.3, 0.9, and 1.2 years). In East Germany and Poland, the overall improvement was largely attributable to falling mortality among men aged 40-64, while those over 65 contributed the largest proportion to life expectancy gains in women. The change in deaths among men aged 15-39 accounted for 0.4 of a year to life expectancy at birth in East Germany and Poland, attributable largely to greater decreases from external causes. Among those over 40, absolute contributions to changing life expectancy were greater in the former GDR than in the other two entities in both sexes, largely attributable to circulatory diseases. A persisting East-west life expectancy gap in Germany of 2.1 years in men in 1997 was largely attributable to external causes, diseases of the digestive system and circulatory diseases. Higher death rates from circulatory diseases among the elderly largely explain the female life expectancy gap of approximately one year. CONCLUSIONS: This study provides further insights into the health effects of political transition. Post-transition improvements in life expectancy and mortality have been much steeper in East Germany compared with Poland. Changes in dietary pattern and, in Germany, medical care may have been important factors in shaping post-transition mortality trends.     

Berliners' models of heart disease causation

Following the collapse of socialism and subsequent German reunification, cardiac mortality rose unexpectedly in the former East Germany; although rates improved by mid-decade, a West/East health gradient persisted. Psychosocial stress from regime change, postsocialism, was one hypothesis proposed to explain the health transition. Absent from the scholarly conversation were individuals' own assessments of their illness experiences in this time of social upheaval. I hypothesized that such data might illuminate processes linking illness and social change. I analyzed illness narratives of East and West Berliners with heart disease, attending to subjective notions of causation. Both groups cited nonmodifiable and modifiable risk factors; half of the East Berliners incorporated additional material that referenced processes associated with postsocialism. I propose that ethnographic investigations of illness experiences can contribute to the development of more culturally relevant, comprehensive hypotheses of nonbiologic risk factors for cardiovascular disease.     

Regional variation and time trends in mortality from ischaemic heart disease: East and West Germany 10 years after reunification

STUDY OBJECTIVE: Within Europe, a pronounced geographical gradient of mortality from ischaemic heart disease has been observed with the highest burden in the north east and the lowest in the south west. The study objective was to compare mortality from ischaemic heart disease between former East and West Germany since reunification. DESIGN: Analyses of age standardised mortality rates from ischaemic heart disease (ICD-9 410-414, ICD-10 I20-I25) between 1990-1991 and 2000. SETTING: Former East and West Germany. MAIN RESULTS: After a peak in the early 1990s, mortality from ischaemic heart disease has substantially declined in both parts of Germany (from 222 to 169 per 100 000 in the East and from 150 to 116 per 100 000 in the West). The regional difference, however, remained rather constant: the rate ratio between the pooled mortality in the East compared with the West was 1.51 (95% CI 1.46 to 1.56) in 1991 and 1.45 (95% CI 1.39 to 1.50) in 2000. These rate ratios were higher in women (1.63 in 1991 and 1.52 in 2000) compared with men (1.45 and 1.44, respectively). CONCLUSIONS: Within Germany, there has been a pronounced east-west gradient of mortality from ischaemic heart disease since reunification. Further insight into possible underlying reasons may lead to improved preventive strategies.     

Vaccine development for emerging virulent infectious diseases

The recent outbreak of Zaire Ebola virus in West Africa altered the classical paradigm of vaccine development and that for emerging infectious diseases (EIDs) in general. In this paper, the precepts of vaccine discovery and advancement through pre-clinical and clinical assessment are discussed in the context of the recent Ebola virus, Middle East Respiratory Syndrome coronavirus (MERS-CoV), and Zika virus outbreaks. Clinical trial design for diseases with high mortality rates and/or high morbidity in the face of a global perception of immediate need and the factors that drive design in the face of a changing epidemiology are presented. Vaccines for EIDs thus present a unique paradigm to standard development precepts.     

Notifiable disease surveillance and practicing physicians

Primary care physicians in Germany are essential participants in infectious disease surveillance through mandatory reporting. Feedback on such surveillance should reflect the needs and attitudes of these physicians. These issues were investigated in a questionnaire survey among 8,550 randomly sampled physicians in Germany in 2001. Of the 1,320 respondents, 59.3% claimed not to have received any feedback on infectious disease surveillance, and 3.7% perceived feedback as not important. Logistic regression analysis showed that physicians in the former East Germany were 2.2 times more likely to have received feedback than those in the former West Germany. Physicians preferred to receive occasional reports (e.g., in case of outbreaks, 31.6%) as opposed to actively having to search for constantly updated information on the Internet (7.8%). The preferred formats were fax (31.7%), mail (30.9%), and the official organ of the German Medical Association (Deutsches Arzteblatt) (30.5%). Feedback of surveillance data to physicians should be delivered through occasional nonelectronic reports on current issues of local public health importance.     

Social inequities in cardiovascular disease risk factors in East and West Germany.

Social class related differences in prevalence of cardiovascular disease risk factors in Germany were investigated with special emphasis on comparisons between East and West Germany and on time trends. Databases for West Germany are the first and second National Health Survey (survey 1: N = 4794, survey 2: N = 5315), carried out in the framework of the German Cardiovascular Prevention Study, and for East Germany the first GDR-MONICA project (N = 6125). Different social class indices were applied to evaluate social inequities for hypertension, hypercholesterolemia, cigarette smoking, obesity and predicted cardiovascular disease mortality. As a main result, it was found that very similar patterns in the relation between social class characteristics and cardiovascular disease risk factor prevalence occurred for both parts of Germany. Social class gradients were strongest for obesity and weakest for hypercholesterolemia. Analysis of time trends for the period from 1984 to 1988 (for West Germany only) revealed an increase in social inequalities for hypertension in males and cigarette smoking in females. These findings point to the need to focus more on social disadvantaged segments in the population when community based health promotion and disease prevention programs are brought into action.     

Pharmaceutical spending and German reunification: parity comes quickly to Berlin

As the Berlin Wall fell and the population of the Federal Republic of Germany (FRG, West Germany) swelled by 25 percent with the addition of the former German Democratic Republic (GDR, East Germany), the health care system struggled to keep pace. This article examines drug outlays by the statutory sickness funds during the first 2 years of unified operations. It shows that providing equivalent coverage quickly led to equal rates of pharmaceutical consumption nationwide, while in Berlin the former East outdistanced the West by a considerable margin.     

The impact of maternal education on intrauterine growth: a comparison of former West and East Germany

BACKGROUND: Objective of this re-analysis of datasets from former East and West Germany was to examine the influence of maternal education on intrauterine growth in two different political and social systems. METHODS: Information on socio-demographic or lifestyle factors and pregnancy outcome was available for 3374 liveborn singletons from West Germany (1987/88) and 3070 from East Germany (1990/91). Multiple logistic regression was used to estimate the association between maternal education and the risk of delivering a small-for-gestational-age (SGA) newborn below the 10th percentile of birthweight. RESULTS: Women with the lowest education had a significantly elevated risk of SGA newborns compared to women with the highest education in West (odds ratio [OR] = 2.58, 95% CI : 1.17-5.67) and East Germany (OR = 2.77, 95% CI : 1.54- 5.00). The distribution of factors known to influence intrauterine growth varied with education in both states. After adjusting for these factors, women with the lowest educational level still had a higher risk of SGA birth: OR (West) = 2.02, 95% CI : 0.87-4.72; OR (East) = 1.95, 95% CI : 1.02-3.74. CONCLUSIONS: Our findings support the assumption that in former socialist countries health inequalities as a result of social inequalities existed.     

Cancer survival in Eastern and Western Germany after the fall of the iron curtain

Prior to the German reunification, cancer survival was much lower in East than in West Germany. We compare cancer survival between Eastern and Western Germany in the early twenty-first century, i.e. the second decade after the German reunification. Using data from 11 population-based cancer registries covering a population of 33?million people, 5-year age-standardized relative survival for the time period 2002–2006 was estimated for the 25 most common cancers using model-based period analysis. In 2002–2006, 5-year relative survival was very similar for most cancers, with differences below 3?% units for 20 of 25 cancer sites. Larger, statistically significant survival advantages were seen for oral cavity, oesophagus, and gallbladder cancer and skin melanoma in the West and for leukemia in the East. Our study shows that within two decades after the assimilation of political and health care systems, the former major survival gap of cancer patients in Eastern Germany has been essentially overcome. This result is encouraging as it suggests that, even though economic conditions have remained difficult in Eastern Germany, comparable health care provision may nevertheless enable comparable levels of cancer survival within a relatively short period of time.     

Food and nutrient intake in East and West Germany, 8 years after the reunification--The German Nutrition Survey 1998

OBJECTIVE: To explore differences in food and nutrient intake as well as cardiovascular risk factors between the eastern and western parts of Germany in 1998 and to compare food consumption information between 1991 and 1998. DESIGN AND SUBJECTS: In all, 4030 people, aged 18-79 y, sampled from the East and West parts of Germany participated in the German Nutrition Survey (1998) by completing dietary histories and being assessed for cardiovascular risk factors. In a separate analysis, two food frequency data sets were compared from National Health Surveys conducted in 1991 (n = 7466) and in 1998 (n = 4556). RESULTS: In 1998, East Germans consumed more bread, fruit, fish, sausage, offal, and men additionally more cakes/cookies, beer and soft drinks than West Germans. They consumed less cereals, pasta, sweets, leafy vegetables, tea and drinking water, and men less vegetables and wine and women less pastry/crackers, potatoes and animal fat compared with their counterparts in West Germany. East Germans had a higher intake of total vitamin A, retinol, vitamin D, vitamin B12 and chloride, and in addition men of alcohol, and women of monosaccharides. They had a lower intake of total water, vitamin K, calcium, magnesium and manganese, and men of linoleic acid, and women of vitamin E than their West German counterparts. In East Germany, higher mean systolic blood pressure, and total and high-density lipoprotein cholesterol concentrations were found in men, and a lower mean total serum cholesterol concentration found in women compared with West Germany. CONCLUSION: Differences in food intake between the eastern and western parts of Germany still existed in 1998, although these differences were smaller than those observed 1 y after the reunification.     

Indoor allergen exposure in west and East Germany: a cause for different prevalences of asthma and atopy?

West and East Germans have been living in two different political systems for 40 years. These two populations have become a classic epidemiological example for the hypothesis that lifestyle changes accompanying the industrial and economic development of modern societies are responsible for an increase in the prevalence of atopic diseases. A higher prevalence of atopic sensitization, asthma, and hay fever was found in young West Germans after the unification. It has been hypothesized that this phenomenon was at least partially due to the installation of insulating windows and central heating systems in Western homes, favoring the growth of microorganisms like mites and moulds and increasing indoor allergen exposure. This review summarizes studies that have investigated reservoir concentrations of indoor allergens in public buildings and private homes in East and West Germany. Whereas a higher prevalence of atopic sensitization in West Germans was found for nearly all tested allergens (cat, mite, pollen), allergen exposure was higher only for cat allergens, but probably not for mite and cockroach allergens or moulds. The published data do not support the view that the differences in specific sensitization are caused by differences in the exposure to specific allergens.     

Individual risk factors, health behaviour and mortality developments in Germany from 1984 to 1998

The aim of the study is to investigate the contribution by the risk factors smoking, overweight, high blood pressure, physical inactivity and regular alcohol consumption to the total mortality development of the general population in Germany. Data are a mortality follow-up conducted by the Federal Institute for Population Research during 1984 - 1998 in West Germany and 1991-1998 in East Germany. 8474 persons participated at baseline in West Germany in the age group 31-69 years, and 1546 persons participated at baseline in East Germany in the age-group 40-79 years. The vital status in the year 1998 could be determined in West Germany for 86.5% and in East Germany for 97.0%. In the observation period 1986-1998 for West Germany 17.2% of the males died and 8.6% of the females. In East Germany between 1991-1998 9.6% of the males died and 6.7% of the females. The statistical analysis, based on the Cox regression showed for West Germany except for overweight in males throughout a significant contribution of the risk factor load on total mortality. The highest relative risks were found for strong smokers (males: RR = 3.47, p < 0.001, females: RR = 3.62, p < 0.001). The relative mortality risk for persons with three and more risk factors yielded in males 4.88 (p < 0.001) and in females 5.05 (p < 0.001). These findings clearly demonstrate that already a few risk markers of the individual health behaviour have a strong impact on the total mortality development in Germany. The mortality risk is about five times higher for persons with three and more risk factors. This indicates the need for preventive measures targeting high-risk population groups.     

Estimating the contribution of mortality selection to the East–West German mortality convergence

Background

Before German reunification, old-age mortality was considerably higher in East Germany than West Germany but converged quickly afterward. Previous studies attributed this rapid catch-up to improved living conditions. We add to this discussion by quantifying for the first time the impact of mortality selection.

Methods

We use a gamma-Gompertz mortality model to estimate the contribution of selection to the East–West German mortality convergence before and after reunification.

Results

We find that, compared to the West, frailer East Germans died earlier due to deteriorating mortality conditions leading to converging mortality rates for women and men already over age 70 before 1990. After 1990, the selection of frailer individuals played only a minor role in closing the East–west German mortality gap. However, our study suggests that, after reunification, old-age mortality improved quickly because the more robust population in the East benefitted greatly from ameliorating external factors such as health care and better living standards.

Conclusion

Our results from a natural experiment show that selection of frail individuals plays an important role in population-level mortality dynamics. In the case of the German reunification, East German old-age mortality already converged before 1990 because of stronger selection pressure.
