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.

Physical activity and psychopathology: are long-term developmental trajectories of physical activity in children and adolescents associated with trajectories of general mental health problems and of attention-deficit hyperactivity (ADHD) symptoms?

A medium-to-high level of physical activity (PA) may have at least a short-term positive effect on psychopathology in children and adolescents. Hence, the objective of this study was to investigate the long-term effects of PA in non-adult age groups on their general mental health problems and/or ADHD symptoms, using trajectories of concurrent development over a period of 10 years. This study employed data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) collected at three time points (baseline, Wave 1, Wave 2, over 10 years) from 17,640 children and adolescents. Using parent-reported data from the Strengths and Difficulties Questionnaire (SDQ), different developmental trajectories of general mental health problems (SDQ-total) and ADHD symptoms (SDQ-H/I) were identified with latent class mixed models (LCMM) statistics. This was also applied to parent- and self-reported data of three levels of PA. The latter was assessed according to WHO recommendations. The joint probability of class membership for SDQ-total as well as ADHD symptoms with PA was calculated to generate the concurrent developmental trajectories between variables. Results showed a 4-class trajectory model for both SDQ-total and ADHD symptoms among boys and girls. The majority of children and adolescents showed "low general difficulties" and "low ADHD symptoms" over the period of 10 years. Three distinct trajectories in boys and four distinct trajectories in girls were found for PA. Most of the participants showed an "increasing-decreasing activity" trajectory. No statistically significant correlations were found between the different SDQ-total or ADHD symptom trajectories and the trajectories of PA in the two genders. Taken together, our findings did not indicate any significant relationship between waxing and waning PA course over 10 years and various classes of mental health problems for children and adolescents. In contrast to our cross-sectional findings, no steady long-term medium/high-level of PA was present, which could (at least partly) explain the non-significant findings.

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.

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.

[Secondary Data Analysis of Initially Treated In-patients with Schizophrenia in a Model Project in Berlin (According to § 64b SGB V)]. / Sekundärdatenanalyse initial vollstationär behandelter Patienten mit Schizophrenie in einem Berliner Modellprojekt (nach § 64b SGB V).

AIM OF THE STUDY: Schizophrenia is one of the most severe psychiatric diseases. The German health care system still shows gaps in services for chronic psychiatric patients with intense need of treatment. The present article focused on changes in provision of health services for initially treated in-patients with schizophrenia in St. Hedwig hospitals in Berlin according to § 64b SGB V compared to patients receiving regular in-patient treatment. METHODS: By using statutory data, we analyzed target figures. We analyzed patients of 3 cohorts. Propensity Score Matching generated a control group in each cohort. RESULTS: The final analysis showed for schizophrenia patients treated in the model project that the number of hospital stays and overall length of stay decreased, but overall costs decreased only partially. Moreover, the period (in days) until next re-hospitalization was longer, while the sum of contacts to the outpatient sector increased. Conclusions The presented model project achieved the aimed shift of psychiatric health service into the outpatient sector for schizophrenia patients.

[Reference Values for Cardiorespiratory Fitness of the General Population: The German National Health Interview and Examination Survey for Adults (DEGS1) 2008-2011]. / Referenzwerte für die kardiorespiratorische Fitness der allgemeinen Bevölkerung: Die Studie zur Gesundheit Erwachsener in Deutschland (DEGS1) 2008­2011.

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: 25th, 50th and 75th 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. 25th, 50th and 75th 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.

[Unintentional injuries in childhood and adolescence-prevalence, locations, and mechanisms : Results from KiGGS Wave 2 and trends]. / Unfallverletzungen im Kindes- und Jugendalter ­ Prävalenzen, Unfall- und Behandlungsorte, Mechanismen : Ergebnisse aus KiGGS Welle 2 und Trends.

BACKGROUND: Unintentional injuries are one of the most common health problems in childhood and adolescence. Information on the distribution and variation of accident prevalence is an important basis for accident prevention. The second follow-up survey of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2, 2014-17) enables the continuation of non-fatal accident monitoring at the federal level that began with the KiGGS baseline study (2003-06). METHODS: KiGGS Wave 2 is a nationwide cross-sectional survey conducted by the Robert Koch Institute (RKI) with participation of 15,023 children and adolescents aged 0 to 17 (response rate: 40.1%). Parents were interviewed about unintentional injuries of their children. Information on accidents is available from 2429 children and adolescents (1-17 years). Twelve-month prevalences with 95% CI were calculated and comparisons were made between KiGGS Wave 2 and the previous KiGGS surveys. RESULTS: Within the last 12 months, 16.5% of 1­ to 17-year-old children and adolescents were medically treated for an accidental injury, with boys (18.6%) requiring treatment significantly more frequently than girls (14.3%). Of the total, 4.8% had three or more accidents. Every eighth injured child (12.4%) stayed in hospital for at least one night. Children and adolescents under 18 years were most likely to have accidents at home, in educational and care facilities, on playgrounds and in sports facilities. CONCLUSION: Injury risks in childhood and adolescence vary primarily according to age and gender, but also, for example, according to personal and environmental factors. Knowledge of such contextual conditions is of great importance for the development of prevention measures. Since the beginning of the KiGGS study, there have been hardly any changes and no decrease in unintentional injuries in childhood and adolescence.

[Vaccination coverage of children and adolescents in Germany: New data from KiGGS Wave 2 and trends from the KiGGS study]. / Durchimpfung von Kindern und Jugendlichen in Deutschland: Aktuelle Daten aus KiGGS Welle 2 und Trends aus der KiGGS-Studie.

Since the baseline study of the "German Health Interview and Examination Survey for Children and Adolescents (KiGGS)" in 2003-2006, vaccination conditions in Germany have changed and additional vaccinations have been included in the immunization schedule. The current KiGGS data can be used to assess the current vaccination status of 3­ to 17-year-olds and trends in the 1985-2013 birth cohorts.Of the 15,023 total participants in KiGGS Wave 2, 3238 aged 3-17 years participated in the KiGGS Wave 2 examinations and submitted the complete vaccination certificate or were, according to their parents, unvaccinated. In this group, vaccination coverage was high for the majority of vaccinations for both girls and boys. Vaccination coverage has increased in children and adolescents in the last 10 years. This is especially true for vaccines for which there were strong deficiencies in the KiGGS baseline study, such as the hepatitis B and second measles vaccinations in all age groups, the booster dose against pertussis (11- to 17-year olds), as well as the booster dose against tetanus in the 7­ to 10-year-olds.Sociodemographic factors are still determinants of vaccination status. Less than one child in two is vaccinated against hepatitis B (45.9%) when parents state fear of side effects or indicate vaccine skepticism as reasons against vaccinations. Despite significant increases, vaccination coverage at the end of the second year of life is still far below 95% for all vaccinations (measles: 1st dose: 88.6%; 2nd dose: 64.4%) even in the most recent birth cohorts.The results show where further efforts are needed to increase vaccination coverage by the remaining last percentage points, achieve the timely delivery of all vaccinations listed in the immunization schedule, as well as meet the defined elimination goals.

Updated prevalence rates of overweight and obesity in 11- to 17-year-old adolescents in Germany. Results from the telephone-based KiGGS Wave 1 after correction for bias in self-reports.

BACKGROUND: The nationwide "German Health Interview and Examination Survey for Children and Adolescents" (KiGGS), conducted in 2003-2006, showed an increase in the prevalence rates of overweight and obesity compared to the early 1990s, indicating the need for regularly monitoring. Recently, a follow-up-KiGGS Wave 1 (2009-2012)-was carried out as a telephone-based survey, providing self-reported height and weight. Since self-reports lead to a bias in prevalence rates of weight status, a correction is needed. The aim of the present study is to obtain updated prevalence rates for overweight and obesity for 11- to 17-year olds living in Germany after correction for bias in self-reports. METHODS: In KiGGS Wave 1, self-reported height and weight were collected from 4948 adolescents during a telephone interview. Participants were also asked about their body perception. From a subsample of KiGGS Wave 1 participants, measurements for height and weight were collected in a physical examination. In order to correct prevalence rates derived from self-reports, weight status categories based on self-reported and measured height and weight were used to estimate a correction formula according to an established procedure under consideration of body perception. The correction procedure was applied and corrected rates were estimated. RESULTS: The corrected prevalence of overweight, including obesity, derived from KiGGS Wave 1, showed that the rate has not further increased compared to the KiGGS baseline survey (18.9 % vs. 18.8 % based on the German reference). CONCLUSION: The rates of overweight still remain at a high level. The results of KiGGS Wave 1 emphasise the significance of this health issue and the need for prevention of overweight and obesity in children and adolescents.

Nonpharmacologic Pain Management Interventions in German Nursing Homes: A Cluster Randomized Trial.

The reported prevalence of pain among nursing home residents (NHRs) is high. Insufficient use of analgesics, the conventional pain management strategy, is often reported. Whether and to what extent nonpharmacologic therapies (NPTs) are used to manage the pain of NHRs in Germany is largely unknown. The aim of this cluster-randomized trial was to assess the NPTs provided and to enhance the application and prescription of NPTs in NHRs on an individual level. There were six nursing homes in the intervention group and six in the control group. There were 239 NHRs, aged ≥65 years, with an average Mini-Mental State Examination score of at least 18 at baseline. Pain management interventions (cluster level) included an online course for physicians and 1-day seminar for nurses. Data on NPT applied by nurses and therapeutic NPT prescribed by physicians were obtained from residents' nursing documentation. Face-to-face interviews with NHRs assessed the NPT received. At baseline, 82.6% of NHR (mean age 83 years) were affected by pain, but less than 1 in 10 received NPT. The intervention did not result in a significant increase in the NPT applied by nurses, but did significantly increase the therapeutic NPT prescribed by physicians. Residents were active in using NPT to self-manage their pain. Given the prevalence of pain in NHRs, there is a clear need to improve pain management in this population. Extended use of NPT offers a promising approach. We recommend that nurses provide residents with education on pain-management techniques to support them in taking a proactive role in managing their pain.

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.

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.

Haemolysis risk in methylene blue treatment of G6PD-sufficient and G6PD-deficient West-African children with uncomplicated falciparum malaria: a synopsis of four RCTs.

PURPOSE: Methylene blue (MB), which was recently tested in a number of clinical malaria studies in Burkina Faso, is currently investigated for its benefit when added to artemisinin-based combination therapy. Together with a number of other antimalarials, MB is on the list of drugs which potentially induce haemolysis in patients with G6PD deficiency. Ruling out safety concerns is of major importance during drug development. METHODS: A pooled analysis was performed with patient data from four clinical studies conducted in West African children with falciparum malaria between 2003 and 2007. The primary endpoints were haemoglobin levels over time as well as haemolysis in G6PD-deficient (n = 199) and G6PD-sufficient (n = 806) children treated with MB-containing (n = 844) compared to children without MB-containing (n = 161) drug regimens. RESULTS: In the chosen model, the haemoglobin time course was significantly influenced by the G6PD genotype and the MB dose. In children with hemi- or homozygous G6PD (A-) deficiency, MB treatment with 15 mg/kg per day was associated with a significant reduction in Hb values which reached a minimum of 8.5 g/dl. Two episodes of haemolysis occurred (out of 1005 children); one in a girl heterozygous for G6PD deficiency and one in a hemizygous boy, both had received MB. CONCLUSIONS: MB treatment of malaria in Africa is associated with slightly reduced haemoglobin values in children with a full G6PD defect compared to non-G6PD deficient children. This effect appears to be of limited clinical relevance but needs to be monitored.

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.

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.

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

BACKGROUND: Germany has a long history of migration. In 2020, more than 1 person in every 4 people 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 citizenship. People with a history of migration are not represented proportionately to the population within public health monitoring at the Robert Koch Institute, thus impeding differentiated analyses of migration and health. To develop strategies for improving the inclusion of people with a history of migration in health surveys, we conducted a feasibility study in 2018. The lessons learned were implemented in the health interview survey German Health Update (Gesundheit in Deutschland aktuell [GEDA]) Fokus, which was conducted among people with selected citizenships representing the major migrant groups in Germany. OBJECTIVE: GEDA Fokus aimed to collect comprehensive data on the health status and social, migration-related, and structural factors among people with selected citizenships to enable differentiated explanations of the associations between migration-related aspects and their impact on migrant health. METHODS: GEDA Fokus is 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 1200 participants per group. The gross sample of 33,436 people was drawn from 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 (web-based and paper-based); in larger 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 were collected from November 2021 to May 2022. RESULTS: Overall, 6038 respondents participated in the survey, of whom 2983 (49.4%) were female. The median age was 39 years; the median duration of residence in Germany was 10 years, with 19.69% (1189/6038) of the sample being born in Germany. The overall response rate was 18.4% (American Association for Public Opinion Research [AAPOR] response rate 1) and was 6.8% higher in the municipalities where personal interviews were offered (19.3% vs 12.5%). Overall, 78.12% (4717/6038) of the participants self-administered the questionnaire, whereas 21.88% (1321/6038) took part in personal interviews. In total, 41.85% (2527/6038) of the participants answered the questionnaire in the German language only, 16.69% (1008/6038) exclusively used the translation. 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.

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.

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.

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.
