Toxoplasma gondii Infections and Associated Factors in Female Children and Adolescents, Germany

In a representative sample of female children and adolescents in Germany, Toxoplasma gondii seroprevalence was 6.3% (95% CI 4.7%-8.0%). With each year of life, the chance of being seropositive increased by 1.2, indicating a strong force of infection. Social status and municipality size were found to be associated with seropositivity.

New Reference Values for Thyroid Volume by Ultrasound in German Children and Adolescents from a Population-Based Study

CONTEXT

Reliable reference values for thyroid ultrasound measurements are essential to effectively guide individual diagnostics and direct health care measures at the population level, such as iodine fortification programs. However, the latest reference values for total thyroid volume (Tvol) provided by the WHO in 2004 only apply to the 6 to 12-year-old age group and are limited to countries with a long history of iodine sufficiency, which does not reflect the situation in most European countries, including Germany.

OBJECTIVE

The present aims to derive up to date thyroid volume ultrasound reference values in German children and adolescents.

DESIGN

Data from the baseline assessment of a nationwide study in German children and adolescents (KiGGS) conducted between 2003 and 2006 were used to determine sex-specific reference values for Tvol in thyroid-healthy participants aged 6 to 17 years by age and body surface area (BSA) according to the Lambda-Mu-Sigma (LMS) method.

RESULTS

Data from 5559 participants were available for reference chart construction (girls: 2509 (45.1%)). On average, the 97th percentile is 33.4% and 28.5% higher than the corresponding WHO's reference values for boys and girls, respectively. These findings are consistent with most other studies in German and European children and adolescents at a similar time of investigation. Notably, the sample used for this study was iodine-sufficient according to WHO criteria.

CONCLUSIONS

The reference values provided by the WHO are overly conservative for this population and could potentially apply to other European countries with a similar history of iodine supply.

Gender equality and smoking among 15 to 25 year olds-a time-based ecological analysis of developments in Germany from 1960 to 2005

Introduction

Smoking is a major risk factor for premature death and health problems in which there are significant gender differences in the prevalence of smoking. This ecological study examines the correlation between changes in gender equality and prevalence of smoking among young adults (15-25 years old) in Germany over a period of 45 years (1960-2005).

Methods

Gender inequality was measured using the United Nations Gender Inequality Index (GII), which is composed of three dimensions; health, empowerment and labour market. It was calculated for the entire registered German population in five-year intervals with values between 0 and 1 (1 = highest inequality). The smoking prevalence of young women and men in Germany was established using a reconstruction method. A gender smoking ratio (GSR) with values between 0 and 1 was determined (1 = identical smoking prevalence among men and women). The smoking behaviour was illustrated and stratified by education. The correlation between the GII and the GSR was analysed.

Results

The GII decreased from 0.98 to 0.56 between 1960 and 2005. The GSR increased from 0.34 to 0.93. There was a strong negative correlation between the GII and the GSR (r = -0.71). The strength of the correlation fell slightly as the level of education decreased. An increase in gender equality as measured by the GII came along with similarities of smoking prevalence between young women and young men.

Conclusion

Successful tobacco prevention among young women and men may benefit from involving experts in gender-specific public health research to develop counter-advertising and gender-specific information as needed.

Study on Health of Older People in Germany (Gesundheit 65+): objectives, design and implementation

Background

The longitudinal population-based study Gesundheit 65+ aimed to close data gaps on health and well-being of older adults in Germany in times of the COVID-19 pandemic.

Methods

The target population comprised persons 65 years and older permanently residing in Germany and with sufficient German language skills. Proxy interviews were possible and consent from legal representatives was obtained as necessary in order to enable participation of physically or cognitively impaired persons. A two-stage sampling process, was used to draw 128 primary sample points (PSUs) and within these PSUs sex- and age-stratified random samples were drawn from population registries. A mixed-mode design was applied to contact the study population and for data collection. Data were collected between June 2021 and April 2023. Participants were surveyed a total of four times at intervals of four months. At month 12 participants were offered a home visit including a non-invasive examination. Data on all-cause mortality and information on neighborhood social and built environment as well as health insurance data will be linked to primarily collected data at the individual level.

Discussion

Results will inform health politicians and other stakeholders in the care system on health and health care needs of older people in Germany.

Seroprevalence, seroconversion and seroreversion of Borrelia burgdorferi-specific IgG antibodies in two population-based studies in children and adolescents, Germany, 2003 to 2006 and 2014 to 2017

BackgroundLyme borreliosis (LB), caused by Borrelia burgdorferi (Bb), is the most common tick-borne infection in Germany. Antibodies against Bb are prevalent in the general population but information on temporal changes of prevalence and estimates of seroconversion (seroincidence) and seroreversion are lacking, especially for children and adolescents.AimWe aimed at assessing antibodies against Bb and factors associated with seropositivity in children and adolescents in Germany.MethodsWe estimated seroprevalence via two consecutive cross-sectional surveys (2003-2006 and 2014-2017). Based on a longitudinal survey component, we estimated annual seroconversion/seroreversion rates.ResultsSeroprevalence was 4.4% (95% confidence interval (CI): 3.9-4.9%) from 2003 to 2006 and 4.1% (95% CI: 3.2-5.1%) from 2014 to 2017. Seroprevalence increased with age, was higher in male children, the south-eastern regions of Germany and among those with a high socioeconomic status. The annual seroconversion rate was 0.3% and the annual seroreversion rate 3.9%. Males were more likely to seroconvert compared with females. Low antibody levels were the main predictor of seroreversion.ConclusionWe did not detect a change in seroprevalence in children and adolescents in Germany over a period of 11 years. Potential long-term changes, for example due to climatic changes, need to be assessed in consecutive serosurveys. Seroconversion was more likely among children and adolescents than among adults, representing a target group for preventive measures. Seroreversion rates are over twice as high in children and adolescents compared with previous studies among adults. Thus, seroprevalence estimates and seroconversion rates in children are likely underestimated.

Hepatitis A seroprevalence, vaccination status and demographic determinants in children and adolescents in Germany, 2014-2017, a population-based study

Children play an important role in hepatitis A virus (HAV) transmission but, due to frequent asymptomatic or mild courses, these infections are underrecognized in routine surveillance. Here, we analyzed hepatitis A (HA) seroprevalence, vaccination status and demographic determinants and estimated previous HAV infections in a cross-sectional population-based study of children and adolescents with residence in Germany 2014-2017, performing weighted univariable and multivariable logistic regression. Of 3567 participants aged 3-17 years, serological results were available for 3013 (84.5%), vaccination records for 3214 (90.1%) and both for 2721 (76.3%). Of 2721 with complete results, 467 (17.2%) were seropositive, thereof 412 (15.1%) with and 55 (2.0%) without previous HA vaccination, indicating previous HAV infection. Seropositivity was associated with age, residence in Eastern states, high socioeconomic status and migration background with personal migration experience. Participants with migration background and personal migration experience also had the highest odds ratios for previous HAV infection. Germany remains a country with very low HA endemicity. The current vaccination recommendations focusing on individuals with a high risk for HAV exposure (e.g. travelers to endemic countries) or severe disease appear appropriate. Migration and travel patterns as well as the endemicity in other countries influence the domestic situation, warranting further monitoring.

'German Health Update Fokus (GEDA Fokus)': Study Protocol of a Multilingual Mixed-mode Interview Survey among Residents with Croatian, Italian, Polish, Syrian or Turkish Citizenship in Germany

BACKGROUND

Germany has a long history of migration. In 2020, more than every fourth person had a statistically defined, so-called 'migration background' in Germany, meaning that the person or at least one of their parents was born with a citizenship other than German. People with a history of migration are not represented proportionately to the population within public health monitoring at the Robert Koch Institute (RKI), thus impeding differentiated analyses on migration and health. In order to develop strategies to improve the inclusion of people with a history of migration in health surveys, we conducted a feasibility study in 2018. Lessons learned were implemented in the health interview survey GEDA Fokus which was conducted among people with selected citizenships representing the major migrant groups in Germany.

OBJECTIVE

The main objective of GEDA Fokus was to collect comprehensive data on the health status and social, migration-related, and structural factors among people with selected citizenships in order to enable differentiated explanations on the associations between migration-related aspects and their impact on migrant health.

METHODS

GEDA Fokus was an interview survey among people with Croatian, Italian, Polish, Syrian, or Turkish citizenship living in Germany aged 18 - 79 years, with a targeted sample size of 1,200 participants per group. The gross sample of 33,436 people was drawn out of the residents' registration offices of 99 German municipalities based on citizenship. Sequentially, multiple modes of administration were offered. The questionnaire was available for self-administration (online and paper-based); in bigger municipalities, personal or phone interviews were possible later on. Study documents and the questionnaire were bilingual, in German and the respective translation language depending on the citizenship. Data collection took place from November 2021 until May 2022.

RESULTS

Overall, 6,038 respondents participated in the survey, 49.4% were female. The median age was 39 years, and the median duration of residence in Germany was 10 years, with 19.7% of the sample being born in Germany. The overall response rate was 18.4% (AAPOR response rate 1) and was 6.8% higher in the municipalities where personal interviews were offered (19.3% vs. 12.5%). Overall, 78.2% administered the questionnaire on their own, while 21.9% took part in a personal interview. A total of 41.9% answered the questionnaire in German language only, 16.7% exclusively used the translation, and 41.4% used both languages in the bilingual version of the questionnaire.

CONCLUSIONS

Offering different modes of administration, as well as multiple study languages, enabled us to recruit a heterogeneous sample of people with a history of migration. The data collected will allow differentiated analyses of the role and interplay of migration-related and social determinants of health and their impact on the health status of people with selected citizenships.

CLINICALTRIAL

Participation of the adult population in preventive measures for non-communicable diseases during the COVID-19 pandemic in 2020/2021

Background

In 2020/2021, the COVID-19 pandemic and the protective measures associated therewith severely limited the opportunity to participate in prevention and health promotion measures. The article examines the utilisation of the measures and possible factors that are associated with a lower participation during these pandemic years.

Methods

It is based on data acquired between March and August 2021 from the study 'COVID-19 vaccination rate monitoring in Germany' (COVIMO), a cross-sectional telephone survey. The data was used to examine the participation in preventive measures in the last 12 months in terms of sociodemographic factors and to analyse a decreased participation with regard to pandemic-related factors. The analysis sample includes individuals aged 18 years and over (n=3,998).

Results

63% of participants generally did not use these programmes, 7% indicated an unchanged participation, 28% reported having participated in fewer measures, and 2% in more measures. Men reported significantly more often than women that they generally do not participate in prevention and health promotion measures. A relevant pandemic-related factor for decreased participation of men was the less clearly perceived comprehensibility of the regulations against the spread of SARS-CoV-2.

Conclusions

Prevention and health promotion should be part of the contingency planning in epidemically significant situations to prevent a decreased participation and to promote health and gender-related equal opportunities even in a crisis.

Depressive symptoms in the general population before and in the first year of the COVID-19 pandemic: Results of the GEDA 2019/2020 study

BACKGROUND

Study results on the impact of the COVID-19 pandemic on mental health in the first year of the pandemic are contradictory. The GEDA 2019/2020 study makes it possible to examine changes in depressive symptoms in the population.

METHODS

A standardised telephone interview was used to survey a random sample of the population in Germany aged 15 and older. To exclude seasonal effects, 10,220 interviewees from the period April 2019 to January 2020 were compared with 11,900 from the period April 2020 to January 2021. Depressive symptoms were assessed with the internationally established 8-item Patient Health Questionnaire (PHQ-8).

RESULTS

The prevalence of depressive symptoms decreased from 9.2% to 7.6% in the first year of the pandemic. Changes differ between women and men as well as between age and education groups. The analysis of individual symptoms suggests that it is not about a reduction of mental disorders of the depressive type in the narrower sense, but rather a decrease in stress-associated individual symptoms.

CONCLUSIONS

The decrease in stress-associated depressive symptoms in parts of the population can be interpreted as an indication that pandemic-related changes in everyday life and the working environment may have had a positive effect on individual areas of mental health in certain groups, at least temporarily in the first year of the pandemic. The continuing strong social inequality in depressive symptoms to the disadvantage of low education groups confirms that the need for social situation-related health promotion and prevention with regard to the living and working conditions of socially disadvantaged people must not be lost sight of in times of pandemic. For groups in the population that partly showed a worsening of symptoms in this phase of the pandemic, e.g. the diminished ability to concentrate of very old men, targeted support options should be created in the future.

Age at menarche relates to depression in adolescent girls: Comparing a clinical sample to the general pediatric population

CONTEXT

The timing of puberty, physical features of pubertal development, and hormones are closely intertwined but may also individually contribute to the risk for depression and depression severity. Additionally, their effects on mood may depend on depression severity, but previously this has only been studied in mostly subclinical depression.

METHODS

In 184 girls from a single psychiatric hospital with significant depressive symptoms (Beck Depression Inventory-II score > 13), the relationship between depression severity and age at menarche (AAM), pubertal status, and gonadal/adrenal hormones (estradiol, progesterone, DHEA-S, androstenedione, testosterone, dihydrotestosterone) was investigated. Moreover, AAM in depressed girls was compared to that from a representative sample of German adolescents without a psychiatric disorder (N = 1674). Androgen levels were compared to those of age- and sex-matched controls (N = 59).

RESULTS

AAM but not pubertal stage or biochemical parameters related to depression. Girls with AAM at the lower normative range of pubertal development were 61 % more likely to develop depression and scored 4.9 points higher on the depression scale than girls experiencing menarche at the population average. Androstenedione levels were increased in the psychiatric sample, but neither androgen nor gonadal hormone levels were associated with depression severity.

LIMITATIONS

The study is cross-sectional.

CONCLUSIONS

These observations confirm previous studies in mostly subclinical depression and highlight the importance of AAM for adolescent depression. Thus, AAM could be considered a prognostic factor for a clinical risk score assessing the probability of adolescent depression. Moreover, these findings suggest fostering efforts that address risk factors that contribute to an earlier AAM.

Prevalence and self-rated health and depression of family members affected by addictive disorders: results of a nation-wide cross-sectional study

AIMS

To estimate the prevalence of family members affected by addictive disorders (FMA) with regard to various types of addictive disorders, and self-rated health and depression in the general population.

DESIGN

Cross-sectional general population survey.

SETTING

The German Health Update study (GEDA) 2014/2015, a nationally representative panel of German residents aged 15 years or older.

PARTICIPANTS

A total of 24 824 residents aged 15 years or older.

MEASUREMENTS

Participants were asked if they had a family member with current or past addictive disorder, the type of addiction and the relationship status. In addition, self-rated health and depression were assessed using standardized questionnaires.

FINDINGS

Of the respondents, 9.5% [95% confidence interval (CI) = 9.0-10.0] reported being affected by a current addictive disorder of a relative (cFMA), with a further 4.5% (95% CI = 4.2-4.9) reported having been affected by the addictive disorders of a relative in the past but not within the last 12 months (pFMA). Most FMAs reported having been affected by disorders due to alcohol, followed by cannabis and other drugs. Compared with life-time non-FMAs, FMAs reported significantly (P < 0.001) higher odds ratios for depression (cFM = 2.437; 95% CI = 2.082-2.853; pFMA = 1.850; 95% CI = 1.519-2.253) and ill-health (cFMA = 1.574; 95% CI = 1.374-1.805; pFMA = 1.297; 95% CI = 1.082-1.555).

CONCLUSIONS

In Germany, family members affected by addictive disorder are a substantial group within the general population. This group is characterized by ill-health and has not yet been adequately addressed by the addiction treatment system.

Participation in prevention measures during the corona pandemic in Germany in 2020/21

Background

The availability and use of preventive measures such as diet courses, sports groups, and counselling services were hindered by containment measures set by the German government and local authorities to reduce the spread of the COVID-19 pandemic. Regulations on contact restriction, closure of sport and leisure facilities made it difficult to use prevention programs in 2020 and 2021. So far, no information is available to what extent the participation of the population in prevention programs has changed as a result of the pandemic and whether there are group differences regarding socio-demographic characteristics.

Methods

We used standardized telephone interviews of the adult German-speaking population to ask for changes in the participation in prevention measures in the last 12 months as a result of the corona pandemic. The data were collected between 17.3.2021 and 18.08.2021 in four cross-sectional surveys and is representative of the population aged 18 years and older in Germany. Analyses of the weighted and pooled data were conducted for n = 3,998 individuals by gender, age and education.

Results

Almost one third of the respondents reported a lower use of programs (28.3%). An unchanged use of the programs was stated by 6.5%, a higher use by 2.1%. 63.2% said they did not use such programs. More women (33.6%) than men (22.7%) reported reduced pandemic-related use (p &lt; 0.0001). For women, we observed a difference between age and education groups, but not for men: Lower participation was reported by a higher proportion of older than younger women (p &lt; 0.0001). More women with high education reported an increased use than ones with low education (p = 0.003) (preliminary results).

Conclusions

The observed differences indicate to different barriers to use prevention measures during the pandemic, especially for women. To promote equal opportunities, resilient structures of prevention and health promotion should be built for future crises in advance.

Key messages

How much do adults sit? Results from the German Health Update (GEDA 2019/2020-EHIS)

Background

Sedentary behaviour is increasingly perceived as a risk factor for the development of diseases and for increased mortality. In particular, increased time spent sitting in combination with low physical activity seems to have negative health consequences.

Methods

In the nationwide cross-sectional study German Health Update (GEDA 2019/2020-EHIS), the indicator 'sitting' was captured by the self-report of the participants.

Results

For at least eight hours a day, 16.7% of women and 22.3% of men sit: Men more often than women, younger persons more often than older persons and the proportion increases significantly from the low to the high education group. Similarly, about one fifth of adults in Germany sit for at least four hours a day and do not engage in physical activity in their leisure time.

Conclusion

The results indicate that preventive measures are needed to reduce time spent sitting and increase physical activity.

Smoking behaviour and passive smoke exposure of adults - Results from GEDA 2019/2020-EHIS

Background

Smoking is a significant health risk and the leading cause of premature death. Passive smoke causes the same negative effects on health as smoking, albeit to a lesser extent. The reduction of tobacco consumption and the protection against passive smoke are thus important health objectives.

Methods

The study German Health Update (GEDA 2019/2020-EHIS) is a cross-sectional telephone survey (04/2019 to 09/2020) of the resident population in Germany with questions relating to the current smoking behaviour and relating to the passive smoke exposure. The analysis sample comprises 22,708 persons from 18 years of age.

Results

24.0% of women and 33.9% of men from 18 years of age smoke currently, at least occasionally. Among both sexes, adults from 65 years of age smoke significantly more rarely than adults in the younger age groups. 4.1% of adults, who do not smoke themselves, are subjected daily to passive smoke exposure indoors. This affects in particular young adults and men. There are educational differences in tobacco consumption and in passive smoke exposure to the disadvantage of adults from lower educational groups.

Conclusions

In Germany, there is still a need for action for effective measures for tobacco prevention, smoking cessation and tobacco control policy, which are effective in all population groups and which take into account the concerns of socially disadvantaged groups.

Physical activity and the development of general mental health problems or attention-deficit hyperactivity disorder (ADHD) symptoms in children and adolescents: A cross-lagged panel analysis of long-term follow-up epidemiological data

Studies have shown that physical activity (PA) can provide a helpful, low-risk, and cost-effective intervention for children and adolescents suffering from mental health problems. This longitudinal study aimed to assess whether PA prevents the development of mental health problems, such as attention-deficit/hyperactivity disorder (ADHD) in children and adolescents. Data were analyzed from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) collected from more than 15.000 children and adolescents at three different time points over a period of more than 10 years. Parents scored the PA of the study participants on three frequency levels according to WHO recommendations, and mental health problems were assessed by means of the Strengths and Difficulties Questionnaire (SDQ). The total problem score (SDQ-Total) and the hyperactivity/inattention symptoms sub-scale (SDQ-H/I) were used in an autoregressive cross-lagged model to examine their relationship with PA. The results showed that PA of boys and girls at preschool age was inversely associated with the occurrence of mental health problems and, in particular, ADHD symptoms about 6 years later. Higher levels of PA were associated with better general mental health and fewer ADHD symptoms at the next time point (Wave 1). These effects were not observed from preadolescence (Wave 1) to adolescence (Wave 2), neither for girls nor for boys. These findings indicate that medium-to-high PA may be a supportive factor for good mental health in children in preschool and elementary school. Future studies will have to show whether PA may be a helpful add-on for interventional programs for improving general mental health and alleviating ADHD symptoms among children and adolescents.

Overweight and obesity among adults in Germany - Results from GEDA 2019/2020-EHIS

BACKGROUND

Overweight and obesity and their associated secondary diseases are of high public health relevance.

METHODS

Self-reported body weight and body height data are available in the study German Health Update (GEDA 2019/2020-EHIS). The body mass index (BMI, kg/m²) was calculated and overweight (including obesity, BMI ≥25 kg/m²) and obesity (BMI ≥30 kg/m²) were derived.

RESULTS

According to this self-report, 53.5% of adults in Germany are overweight, men more often than women. The obesity prevalence for both sexes is 19.0%. The prevalence of overweight and obesity increases with age in both women and men. Obesity is significantly more prevalent in low education groups compared to high education groups. Compared to GEDA 2012, the prevalence of overweight is unchanged, but the obesity prevalence has continued to increase, particularly among 45- to 64-year-olds.

CONCLUSION

The prevention potential of avoiding overweight and obesity remains high.

Social, health-related, and environmental factors influencing sleep problems of children, adolescents and young adults

Sleep is a relevant factor for functioning and well-being of young people. The paper provides a differentiated description of sleep difficulties in this population group including social, health-related, and environmental factors. The analyses included n=6,728 11- to 17-year-olds of the KiGGS baseline study (2003-2006) and 6,072 young adults (age 18-31), who provided information relating sleep in the survey KiGGS Wave 2 (2014-2017). Information from 3,567 people was evaluated at two survey points. 22.0% of the 11- to 17-year-olds reported sleep difficulties. A significant impact for the sex (female), living with a single parent, and with siblings is reflected in the logistic regression. The risk for sleep difficulties increases significantly in the case of mental problems and pain. Among the 18- to 31-year-olds, 19.6% complained of difficulties falling asleep and sleeping through the night. In addition to sex, noise exposure, a low level of education, the professional situation, and living with children were reflected as important influencing factors in the logistic regressions. Over one third of those, who suffered from sleep problems as children and adolescents, also indicated sleep difficulties almost ten years later. The high prevalence of sleep problems and the associated health risks illustrate the high public health relevance of the topic. In addition to sex, health-related and environmental variables also turned out to be significant and need to be considered in the development of interventions.

Prevalence of mental disorders in patients with cancer compared to matched controls - secondary analysis of two nationally representative surveys

AIM

To compare prevalence rates of mental disorders in patients with cancer and general population controls.

METHOD

In two stratified nationally representative surveys, the 12-month prevalence of mental disorders was assessed in 2141 patients with cancer and 4883 general population controls by the standardized Composite International Diagnostic Interview (CIDI). We determined odds ratios (ORs) to compare the odds for mental disorders (combined and subtypes) in cancer patients with age- and gender-matched controls.

RESULTS

The 12-month prevalences rate for any mental disorder was significantly higher in patients with cancer compared to controls (OR 1.28, 95% CI 1.14-1.45). Prevalence rates were at least two times higher for unipolar mood disorders (major depression: OR 2.07, 95% CI 1.71-2.51; dysthymia: OR 2.93, 95% CI 2.13-4.02) and mental disorders due to a general medical condition (OR 3.31, 95% CI 2.32-4.71). There was no significant elevation for anxiety disorders overall (OR 0.95, 95% CI 0.81-1.11). Mildly elevated prevalence rates emerged for post-traumatic stress disorder (OR 1.57, 95% CI 1.11-2.23) and social phobia (OR 1.57, 95% CI 1.07-2.31), while specific phobia (OR 0.82, 95% CI 0.67-1.00) and agoraphobia (OR 0.49, 95% CI 0.33-0.73) were significantly less frequent in cancer.

CONCLUSIONS

While elevated depression rates reinforce the need for its systematic diagnosis and treatment, lower prevalences were unexpected given previous evidence. Whether realistic illness-related fears and worries contribute to lower occurrence of anxiety disorders with excessive fears in cancer may be of interest to future research.

Health situation of adults in Germany - Results for selected indicators from GEDA 2019/2020-EHIS

In this article, we examine selected health indicators for the adult population aged 18 years and older in Germany (n=22,708) from the German Health Update (GEDA 2019/2020-EHIS) conducted between April 2019 and September 2020. These indicators include those of self-assessed health and depressive symptoms as well as chronic physical diseases and conditions. In young adulthood (18 to 44 years), over 80% of participants report good or very good subjective health. During this phase of life, most chronic diseases and conditions are rare, although allergies are frequent, and bronchial asthma and depressive symptoms are not uncommon. From mid adulthood (45 years and older), there is a gradual increase in the prevalence of chronic diseases such as cardiovascular disease, diabetes, chronic obstructive pulmonary disease and osteoarthritis. Over 60% of older adults (65 years and older) report a chronic disease or long-term health problem, while only half continue to report good or very good subjective health. During this stage of life, allergies and depressive symptoms become less prevalent. For some diseases, there are also differences according to gender and level of education. This article demonstrates the high public health relevance of age-associated chronic physical diseases and health related limitations in everyday life in an ageing society as well as the need to provide care for certain health conditions already in young adulthood.

Health-promoting behaviour among adults in Germany - Results from GEDA 2019/2020-EHIS

Health-promoting behaviours are important at any age to prevent diseases and to promote well-being. Using data from GEDA 2019/2020-EHIS, a Germany-wide, representative survey, this article describes how often the adult population in Germany reports certain types of health-promoting behaviour in their everyday lives. The behaviours considered are nonsmoking, low-risk alcohol consumption, achievement of the World Health Organization's (WHO) recommendations on aerobic physical activity, at least daily fruit and vegetable consumption, and maintaining a body weight within the normal range. This article describes the proportion of people who report these behaviours in their everyday lives by gender, age and education level, the number of health-promoting behaviours each person reports and the most common combinations in which they occur. Young adults between 18 and 29 years are most likely to achieve a health-promoting lifestyle. The proportion of people who report at least 150 minutes of physical activity per week and a normal body weight is lower in later adulthood than among 18- to 29-year-olds. The recommendation to eat fruit and vegetables daily is implemented least often of all five aspects of health behaviour under study. Finally, women are more likely to lead a health-promoting lifestyle than men.

German Health Update (GEDA 2019/2020-EHIS) - Background and methodology

Between April 2019 and September 2020, 23,001 people aged 15 or over responded to questions about their health and living conditions for the German Health Update (GEDA 2019/2020-EHIS). The results are representative of the German resident population aged 15 or above. The response rate was 21.6%. The study used a questionnaire based on the third wave of the European Health Interview Survey (EHIS), which was carried out in all EU member states. EHIS consists of four modules on health status, health care provision, health determinants, and socioeconomic variables. The data are collected in a harmonised manner and therefore have a high degree of international comparability. They constitute an important source of information for European health policy and health reporting and are made available by the Statistical Office of the European Union (Eurostat). They also form the basis of the Federal Health Reporting undertaken in Germany. Data collection began in April 2019, just under a year before the beginning of the SARS-CoV-2 pandemic, and continued into its initial phase, as of March 2020. As such, data from the current GEDA wave can also be used to conduct research into the health impact of the SARS-CoV-2 pandemic.

Seroprevalence of Measles-, Mumps-, and Rubella-specific antibodies in the German adult population - cross-sectional analysis of the German Health Interview and Examination Survey for Adults (DEGS1)

BACKGROUND

The WHO European Region targets the elimination of measles, rubella, and the congenital rubella syndrome and welcomes mumps elimination via the joint MMR vaccine. In a push towards this elimination goal, Germany introduced a recommendation on MMR vaccination for adults in 2010 to prevent increasing numbers of measles cases among adults and to strengthen herd immunity.

METHODS

The prevalence of anti-measles, -mumps, and -rubella IgG antibodies was analysed in 7,115 participants between the ages of 18 and 79 years in the German Health Interview and Examination Survey. Risk factors of seronegativity of adults born 1970 or later were determined.

FINDINGS

The seroprevalence of anti-measles IgG antibodies was more than 97% in adults born before 1965 and less than 90% in adults born afterwards. Prevalence and GMTs declined with later years of birth. Seronegativity was associated with two-sided migration background and region of residence in East Germany. For anti-mumps IgG antibodies, the seroprevalence was less than 90% in almost all age groups. Prevalence and GMTs declined with later years of birth. Seronegativity was not associated with any socio-demographic factor. Anti-rubella IgG seropositivity was found in more than 90% of adults born before 1985. GMTs declined in younger age groups. Seronegativity was associated with birth between 1980 and 1993 and male gender. High socio-economic status lowered the odds of being seronegative.

INTERPRETATION

These data reinforce the implementation of the vaccination recommendation for adults and provide the basis for further evaluation of this measure.

Physical Activity Improves Mental Health in Children and Adolescents Irrespective of the Diagnosis of Attention Deficit Hyperactivity Disorder (ADHD)-A Multi-Wave Analysis Using Data from the KiGGS Study

Physical activity (PA) may have positive effects on mental health in children and adolescents. This post hoc study aimed to further investigate the relationship between different frequency levels of PA and general mental health as well as specific hyperactivity/inattention symptoms in children and adolescents.

METHODS

The analyses were based on data drawn from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) study, a regularly conducted large-scale, epidemiological investigation of somatic and mental health of children and adolescents in Germany. Parents were asked about their children's attention deficit hyperactivity disorder (ADHD) records and answered questionnaires concerning any mental health problem behavior of the children and adolescents using the Strengths and Difficulties Questionnaire (SDQ). The overall problem score as well as the hyperactivity/inattention symptoms subscale (SDQ-H/I) were entered as outcomes in a regression model controlling for parental socio-economic status and participants' sex, age, and body mass index (BMI). Cross-sectional analyses were conducted at three time points of the KiGGS study (baseline, wave 1, and wave 2) using general linear models (GLM). This was performed for different age groups (4-5, 6-9, 10-17 years).

RESULTS

Significant negative relationships were found between PA and general mental health problems. For the relationship between PA and SDQ-H/I, different patterns emerged at the three time points. There was no interaction between PA frequency levels and diagnosis of ADHD (ADHD vs. non-ADHD controls) regarding the SDQ total score.

CONCLUSION

This study underlines the importance of a high frequency level of PA for a good mental health status among children and adolescents, irrespective of the diagnosis of ADHD.

Sekundärdatenanalyse initial vollstationär behandelter Patienten mit Schizophrenie in einem Berliner Modellprojekt (nach § 64b SGB V)

Ziel der Studie Schizophrenie zählt zu den schwersten psychiatrischen Erkrankungen. Das deutsche Versorgungssystem weist jedoch für diese und andere chronisch psychisch Erkrankte mit einem intensiven Behandlungsbedarf nach wie vor Lücken auf. Der vorliegende Beitrag fokussiert die Veränderung der Versorgung von initial vollstationär behandelten Patienten mit Schizophrenie, die an den St. Hedwig Kliniken in Berlin in einem Modellprojekt nach § 64b SGB V versorgt werden, im Vergleich zu Patienten in der Regelversorgung.

Methodik Die Zielgrößen wurden mittels Routinedaten erfasst. Dabei wurden 3 Patientenkohorten analysiert. Mittels Propensity Score Matching wurde je Kohorte eine Vergleichsgruppe gebildet.

Ergebnisse Es zeigt sich, dass im Modellprojekt die Anzahl der Krankenhausaufenthalte reduziert wurde, die Gesamtverweildauer gesenkt und Gesamtkosten teilweise gesenkt wurden. Zudem verlängerte sich die Dauer bis zur nächsten Rehospitalisierung, während sich die Gesamtzahl der Kontakte zum ambulanten Sektor erhöhte.

Schlussfolgerung Die angestrebte Verlagerung der Versorgung in den ambulanten Bereich wurde für Patienten mit Schizophrenie in diesem Modellprojekt erreicht.

Pain-Associated Clusters Among Nursing Home Residents and Older Adults Receiving Home Care in Germany

CONTEXT

There are no available data regarding pain-associated clusters among nursing home residents (NHRs) and older adults receiving home care with chronic pain.

OBJECTIVES

To identify and describe pain-associated clusters in NHRs and older adults receiving home care with chronic pain and to explore associations with clusters in both settings.

METHODS

We surveyed 137 NHRs and 205 older adults receiving home care. Clusters were identified using hierarchical agglomerative cluster analysis, using Ward's method with squared Euclidean distances in the proximities matrix. The clusters were characterized based on sociodemographic and clinical characteristics. Multinomial logistic regression was used to identify variables associated with different clusters.

RESULTS

In each setting, we identified three clusters: pain relieved, pain impaired, and suffering severe pain. In the nursing home study and home care study, respectively, the participant distributions were 46.72% and 11.71% in the pain-relieved cluster, 22.63% and 33.66% in the pain-impaired cluster, and 30.66% and 54.63% in the severe-pain cluster. Appropriate pain medication was only detected among pain-relieved NHRs.

CONCLUSION

Overall, differences in pain management exist within the two care settings presented here. There is potential for improvement in both settings. Moreover, there exists a need for clinical interventions aiming at shifting from pain-affected clusters to pain-relieved status.

Online Survey for the Assessment of Generic Health Literacy among Adolescents in Germany (GeKoJu): Study Protocol

The promotion of health literacy at a young age can protect, maintain and improve health across the life course. Yet to date, a sound data basis on adolescent health literacy as a requirement for the development of strategies to promote health literacy has not been given. This paper presents a study protocol for the online survey "Health Literacy Among Adolescents" (GeKoJu) that collects the first nation-wide representative data on self-reported generic health among adolescents aged 14-17 years in Germany. The objectives of the survey are (1) to assess the distribution of generic health literacy among adolescents in Germany, (2) to identify socio-demographic and social factors in regard to health literacy and (3) to assess the association of health literacy and health-related outcomes. The cross-sectional survey was conducted from September 2019 through December 2019. A two-stage stratified cluster sampling strategy was applied. Individuals invited to participate in the survey (N = 6608) were randomly selected among German-speaking adolescents aged 14-17 years, with permanent residence in Germany. Generic health literacy is measured with the "Measurement of Health Literacy Among Adolescents-Questionnaire" (MOHLAA-Q). Data collection also covers questions on health behavior, subjective health status, personal and social resources, socio-demographic and social factors and health services use. Results of the GeKoJu survey will provide data for the development of strategies to promote generic health literacy among families, in schools, communities and health care.

Educational differences in the prevalence of behavioural risk factors in Germany and the EU - Results from the European Health Interview Survey (EHIS) 2

This article examines educational differences in the prevalence of behavioural risk factors among adults and compares the results for Germany with the average from the European Union (EU). Data were derived from the second wave of the European Health Interview Survey, which took place between 2013 and 2015 (EHIS 2). Analyses were conducted using a regression-based calculation of relative and absolute educational differences in the prevalence of behavioural risk factors, based on self-reported data from women and men aged between 25 and 69 (n=217,215). Current smoking, obesity, physical activity lasting less than 150 minutes per week, heavy episodic drinking and non-daily fruit or vegetable intake are more prevalent among people with a low education level than those with a high education level. This applies to Germany as well as the EU average. Overall, the relative educational differences identified for these risk factors place Germany in the mid-range compared to the EU average. However, relative educational differences in current smoking and heavy episodic drinking are more manifest among women in Germany than the EU average, with the same applying to low physical activity among men. In contrast, relative educational differences in non-daily fruit or vegetable intake are less pronounced among women and men in Germany than the average across the EU. Increased efforts are needed in various policy fields to improve the structural conditions underlying health behaviour, particularly for socially disadvantaged groups, and increase health equity.

European Health Interview Survey (EHIS) 2 - Background and study methodology

The scientific assessment of health issues, the design and further development of political guidelines as well as the targeted planning of measures in the European Union (EU) require data on population health. For this reason, all EU Member States regularly collect data on the health status, provision of healthcare, health determinants and socioeconomic situation of their respective populations in the European Health Interview Survey (EHIS). Participants are at least 15 years old and live in private households. The second wave of EHIS (EHIS 2) was conducted between 2013 and 2015. For EHIS 2, each EU Member State drew a nationally representative population sample from population registers, censuses, dwelling registers or other statistical or administrative sources. Data collection modes within individual EU Member States were used, according to nationally established methods, including the use of mixed-mode surveys. Across all EU Member States, data collection took an average of eight months to complete. Member States made considerable efforts to achieve the highest possible response rates. The harmonised EHIS data collected are highly comparable and constitute an important information base for European health policy and health reporting.

[Reference Values for Cardiorespiratory Fitness of the General Population: The German National Health Interview and Examination Survey for Adults (DEGS1) 2008-2011]

AIM OF STUDY

This study aims to provide population-based reference values for heart rate-based indicators of cardiorespiratory fitness for adults with physical activity readiness aged 18 to 64 years living in Germany.

METHODS

Based on data on 2,826 individuals who participated in a submaximal cycle ergometer exercise test as part of the German National Health Interview and Examination Survey for Adults (DEGS1) between 2008 and 2011, we calculated the following indicators: physical working capacity at 150 and 130 beats/min and at 75% of estimated maximum heart rate (PWC150, PWC130 and PWC75%) as well as heart rate-based estimated maximum oxygen uptake (VO₂max). We used the LMS method by Cole & Green 1992 to calculate reference values.

RESULTS

25^th, 50^th and 75^th percentiles of PWC150 were 1.5, 1.77 and 2.08 watts/kg among men and 1.18, 1.44 and 1.69 among women. 25^th, 50^th and 75^th percentiles of PWC130 were 1.16, 1.41 and 1.68 watts/kg among men and 0.81, 1.05 and 1.29 among women. Age-dependent median PWC75% values among men and women were 1.87 - age in years× 0.01 and 1.31 - (age in years/100)²× 0.98, respectively, and VO₂max among men is 41.7 - age× 0.15.

CONCLUSIONS

The references values presented can be used for individual rating of cardiorespiratory fitness among adults living in Germany. Furthermore, they can serve as a basis for regular monitoring purposes.

Hepatitis A virus infections, immunisations and demographic determinants in children and adolescents, Germany

Hepatitis A is a vaccine-preventable disease with a global distribution. It predominantly occurs in regions with inadequate living conditions, but also affects populations in industrialised countries. Children are frequently involved in the transmission of hepatitis A virus (HAV) and thus play a central role in the epidemiology of hepatitis A. Here, we investigated HAV infections, immunisations, and associated demographic determinants in a nationwide, population-based, cross-sectional survey conducted in Germany from 2003-2006. Out of 17,640 children and adolescents, complete data sets (HAV serology, demographic information and vaccination card) were available for 12,249 (69%), all aged 3-17 years. We found protective antibody levels (>=20 IU/L) in 1,755 (14%) individuals, 1,395 (11%) were vaccinated against hepatitis A, 360 (3%) individuals were HAV seropositive without prior hepatitis A vaccination, thus indicating a previous HAV infection. Antibody prevalence (attributable to vaccination or infection) increased significantly with age. Multivariate logistic regression revealed that predominantly children and adolescents with migration background-even if they were born in Germany-are affected by HAV infections. Our results provide a rationale to emphasise existing vaccination recommendations and, moreover, to consider additional groups with a higher risk of infection for targeted vaccination, especially children with a migration background.

Accident injuries of children and adolescents in Germany. Results of the cross-sectional KiGGS Wave 2 study and trends

For children and adolescents, accidents represent an important health risk. Despite decreasing mortality rates, accidental (unintended) injuries remain the most common cause of death for children over the age of one in Germany. Accident injuries can cause considerable and lasting damage on health and development. The possible major implications as well as the potential to prevent accident injuries underline the importance of accident prevention. The German Health Interview and Examination Survey for Children and Adolescents (KiGGS) collects data on unintentional child injuries at regular intervals. Results of the second follow-up survey (KiGGS Wave 2, 2014-2017) show that during the past twelve months 16.5% of children and adolescents aged between 1 and 17 received medical treatment following an accident. Boys suffer injuries from accidents significantly more often than girls (18.6% vs. 14.3%). While the prevalences for older children and adolescents tend to be higher, age generally has little impact on accident rates. Compared to the two previous waves of KiGGS, the prevalences of accident injuries have remained stable.

First results from the study 'Disease knowledge and information needs - Diabetes mellitus (2017)'

Very little research has been undertaken into what people in Germany know about diabetes, the information they may require about the condition, where they look for such information and how they rate the information currently available. In 2017, the Robert Koch Institute (RKI) carried out a nationwide telephone survey aimed at answering these questions. The study entitled 'Disease knowledge and information needs - Diabetes mellitus (2017)' focused on people aged at least 18 years. A total of 2,327 people without diabetes and 1,479 people with diagnosed diabetes were interviewed for the study. First results show that 56.7% of people without diabetes and 92.8% of those with diabetes rate their knowledge about the condition as 'very good' or 'good'. People without diabetes were found to have the strongest need for information in terms of 'lifestyle changes, health promotion and disease prevention', whereas respondents with diabetes stressed the strongest need for information about 'treatment and therapy'. Almost a third of respondents without diabetes have actively sought information about diabetes at least once, mostly via print media. Patients with diabetes stated that their general practitioner was their most frequent source of information about the condition. In both groups, about half of respondents reported that they found it difficult to judge the trustworthiness of the information published in the media about diabetes. The results of the study form part of the German National Diabetes Surveillance, which is coordinated by the RKI. The data are also intended to be used by the Federal Centre for Health Education to develop a strategy to improve the information provided about diabetes.

Hepatitis E virus seroprevalence, seroincidence and seroreversion in the German adult population

A steep rise in Hepatitis E diagnoses is currently being observed in Germany and other European countries. The objective of this study was (i) to assess whether this trend mirrors an increase in infection pressure or is caused by increased attention and testing and (ii) estimate individual and population-based Hepatitis E Virus (HEV) seroconversion and seroreversion rates for Germany. We measured anti-HEV IgG prevalence in 10 407 adults participating in two linked, population-representative serosurveys (total n = 12 971) conducted in 1998 and 2010. In this period, we found a moderate but statistically significant decline of overall anti-HEV IgG prevalence from 18.6% to 15.3%. At both time points, seroprevalence increased with age and peaked in persons born between 1935 and 1959 suggesting a past period of increased infection pressure. Paired samples of individuals participating in 1998 and 2010 (n = 2564) revealed respective seroconversion and seroreversion rates of 6.2% and 22.6% among seronegative and seropositive individuals during 12 years, or 5.2 and 2.9 per 1000 inhabitants per year. This corresponds to a total of 417 242 [95%CI: 344 363-495 971] new seroconversions per year in the German population. While anti-HEV seroprevalence has decreased in the last decade, infection pressure and seroincidence remains high in Germany. Continuously rising numbers of Hepatitis E diagnoses in Europe are likely due to an increased awareness of clinicians and indicate that still there is a gap between incident and diagnosed cases. Studies on the true burden of the disease, specific risk factors and sources of autochthonous infections as well as targeted prevention measures are urgently needed.

Pain, Fear of Falling, and Functional Performance Among Nursing Home Residents: A Longitudinal Study

The aim of this study was to analyze the impact of being pain-affected and fear of falling on functional performance among nursing home residents, longitudinally. We used 6-month follow-up data from a cluster-randomized trial of 12 nursing homes (cluster level) with 239 nursing home residents at baseline (mean age, 95% confidence interval [CI] = 83.04 [81.40, 84.69], 70% women). The longitudinal analysis provided data on pain, fear of falling, functional mobility, and activities of daily living (individual level). The data revealed a trend indicating that pain-relieved nursing home residents showed better functional mobility over time. The results on fear of falling demonstrate obvious differences in the functional performance of nursing home residents cross-sectionally but not longitudinally. Nevertheless, the results underline the importance of an effective pain treatment to prevent decline in functional mobility among nursing home residents. Further longitudinal surveys are needed to verify the findings on functional performance.

KiGGS Wave 2 cross-sectional study - participant acquisition, response rates and representativeness

For the third time, wave 2 of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), which is conducted in the context of health monitoring at the Robert Koch Institute, now provides representative cross-sectional data for Germany. Completed in 2017, data for the cross-sectional component of KiGGS Wave 2 was collected in the form of an interview and examination survey. Interview survey data was collected from 15,023 participants, meaning that the required number of participants has been reached. A randomly selected subgroup of 3,567 participants was also examined. The overall response rate was 40.1%. Differences in response rates were registered regarding certain sociodemographic characteristics. Weighting was applied to compensate for differences in willingness to participate related to age, gender, geographic region, nationality and education factors. Weighting ensures that assessments of the health of children and adolescents in Germany are representative for the population. The data serves to estimate prevalence rates and, through comparison with the results from previous survey waves, to analyse trends. A set of measures were taken to recruit a sufficiently large group of participants and ensure that the net sample reflects the composition of the overall population to the highest degree. For future surveys, further measures ought to be taken in order to improve the integration of hard-to-reach subgroups.

Early detection of breast cancer: the utilization of mammography in Germany

Breast cancer is the most common cancer in women in Germany. In addition to physical examinations (palpation) mammographies are offered every two years to women aged 50 to 69 years as part of the mammography screening programme. For this purpose women are invited in writing and recive a leaflet with information about the background, aims procedures, benefits and possible disadvantages that the screening programme might have. The invitation and the leaflet were revised in 2015 to better support the invited women in making an informed decision about whether they should participate in the programme. In the GEDA 2014/2015-EHIS study, the respondents provided the date of their last mammography and the reason for this. A mammography has been performed on 74.2% of women aged 50 to 69 years within the last two years. 80.7% of these women stated that the reason for this was an invitation sent out by the national screening programme.

The utilization of colonoscopy in Germany

Colorectal cancer is one of the three most common cancers in German adults. There are several legally based examinations for the early detection of colorectal cancer. People aged 50 to 54 years can have a faecal blood test annually. From the age of 55, this test is offered every two years as part of cancer screening, or alternatively a preventive colonoscopy, which can be repeated after ten years if the findings are inconspicuous. However, colonoscopies are also carried out to clarify complaints or other diseases (curative colonoscopy). In the GEDA 2014/2015-EHIS study, the respondents provided the date of their last colonoscopy. No data was collected on the reason why this colonoscopy was performed. 57% of women and 61% of men aged 55 years or older reported that they had a colonoscopy within the last 10 years. New legal regulations envisage the expansion of colorectal cancer screening and its development into an organised, quality-assured early detection programme.

12-month prevalence of self-reported medical diagnoses of depression in Germany

Depression is a frequent mental disorder and has a growing importance in health care provision. In GEDA 2014/2015-EHIS, 9.7% of women and 6.3% of men self-reported having received a medical diagnosis of depression during the past 12 months. For both genders, the rate of self-reported diagnoses of depression is highest in the 45- to 64-year age group. Education thereby plays a significant role. Prevalence for women from low education is about double that of women from high education backgrounds (12.2% compared with 6.5%). The education gradient for men is smaller (7.5% compared with 5.1%). Prevalence rates also differ sharply between federal states (for women, between 5.4% and 13.4%; for men, between 3.3% and 9.4%). These results are discussed in the light of data currently available.

12-month prevalence of asthma among adults in Germany

Asthma is a chronic inflammatory disease of the airways affecting people of all ages. The disease is characterised by a variable narrowing of the bronchia, which may be accompanied by symptoms such as wheezing or shortness of breath. In GEDA 2014/2015-EHIS, 6.2% of respondents aged 18 years or older with complete information on the respective indicator (n=22,671) reported having had asthma during the past 12 months. The 12-month prevalence among women (7.1%) is higher than among men (5.4%). Overall, women and men with a low level of education more often reported having had asthma than those with a higher level of education. In analyses stratified by age and gender, differences in asthma prevalence with regard to educational level are evident among women under 30 years of age. In a comparison of federal states, the prevalence of asthma ranges from 3.0% to 9.7% among women and from 2.9% to 7.0% among men.

12-month prevalence of osteoarthritis in Germany

Osteoarthritis is the most common joint disease worldwide. In the advanced stage the disease is characterised by joint pain and loss of joint functionality. In the Robert Koch Institute's GEDA 2014/2015-EHIS health interview survey, 17.9% of adults over 18 reported having suffered from osteoarthritis during the past twelve months, whereby prevalence for women (21.8%) was higher than for men (13.9%). Osteoarthritis becomes more common with age. Among those aged 65 and over, around half of all women (48.1%) and nearly one third of men (31.2%) are affected. Due to population ageing, the prevalence of osteoarthritis in Germany can be expected to increase further in the future.

Depressive symptoms among adults in Germany

Depressive symptoms imply a loss of quality of life, leading to increased morbidity and mortality as well as increased costs to the healthcare system. Information on the prevalence and distribution of depressive symptoms in the population is essential in light of planning prevention and care. GEDA 2014/2015-EHIS surveyed current depressive symptoms among adults in Germany through the Patient Health Questionnaire (PHQ-8). The surveyed prevalence of 10.1% indicates the widespread occurrence of depressive symptoms, regardless of an actual clinical diagnosis of depression. Prevalence for women (11.6%) is higher than for men (8.6%). Further differences exist concerning age and education as well as regional differences. The results are discussed in the light of the data available so far.

12-month prevalence of osteoporosis in Germany

Osteoporosis is a systemic skeletal disease associated with increased bone fragility, which correspondingly leads to increased bone fractures. In the GEDA 2014/2015-EHIS survey, 7.8% of women and 2.0% of men aged 18 and over reported suffering from osteoporosis during the past 12 months. The share of people reporting osteoporosis increases considerably in the age group 65 and over. Elder women significantly more often report osteoporosis than men. As this was the first time the present indicator for the 12-month prevalence of osteoporosis was evaluated in the context of the European Health Interview Survey (EHIS) 2014/2015, there is no comparative data available.

12-month prevalence of known chronic obstructive pulmonary disease (COPD) in Germany

Chronic obstructive pulmonary disease (COPD) is associated with a high disease burden and is one of the leading causes of death worldwide. Smoking is the key modifiable risk factor for COPD in Germany. GEDA 2014/2015-EHIS surveyed the 12-month prevalence of known COPD using the European indicator on self-reported chronic bronchitis, chronic obstructive pulmonary disease, emphysema. Among adults aged 18 years or older with complete information on the indicator (n=22,702), the 12-month prevalence of known COPD is 5.8% (5.8% for women and 5.7% for men). In both genders, the prevalence increases strongly with age. Overall, the presence of COPD was more often reported by women and men with a low educational level than by those with a higher one. In a comparison of federal states, the 12-month prevalence of known COPD varies between 3.6% and 7.5% for women and 4.3% and 11.2% for men.

Accident injuries of adults in Germany

In 2014, according to estimates by the Federal Institute for Occupational Safety and Health (BAuA), around 9.8 million people in Germany suffered accident injuries. Over 22,000 people died. Federal statistics, however, cannot comprehensively describe accidents in Germany. Here, the Robert Koch Institute health surveys provide an important addition. In the GEDA 2014/2015-EHIS survey, 10.5% of men and 6.9% of women reported that they had suffered accident injuries requiring medical treatment during the past 12 months. Young men aged 18 to 29 have the highest accident risk (18.1%). The overall accident injury figures have hardly changed since the previous GEDA 2012 survey. Preventing accidents is a highly important topic not only for the victims of accidents and their families, but also for society as a whole. According to the World Health Organization, a largely untapped potential for accident prevention remains.
