Prevalence of vaccine-derived hepatitis B surface antibodies in children and adolescents in Germany: results from a population-based survey, 2014-2017. BMC Infect Dis 2024; 24:318. [PMID: 38491438 PMCID: PMC10941582 DOI: 10.1186/s12879-024-09201-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Accepted: 03/06/2024] [Indexed: 03/18/2024] Open
Abstract
INTRODUCTION Childhood vaccination against hepatitis B has been recommended in Germany since 1995. WHO defines a primary vaccination series as successful if the initial hepatitis B surface antibody (anti-HBs) level is ≥ 10 IU/L directly after vaccination. Anti-HBs levels vary depending on the number of doses, type of vaccine, and time interval between the last two doses. In 2021, Germany began to recommend three instead of four doses of polyvalent hepatitis-B-containing vaccines. Our aim was to estimate the proportion of vaccinated children in Germany with anti-HBs levels < 10 IU/L, 10-99 IU/L, and ≥ 100 IU/L by number and type of vaccine, and assess if number of doses and compliance with recommended time interval between the last two doses are associated with an anti-HBs level ≥ 10 IU/L when considering type of vaccine and time since last dose. METHODS We used data from a national cross-sectional study (2014-2017) of children (3-17 years). We excluded participants with unknown vaccination dates, unreadable or incomplete vaccination cards, and hepatitis B virus (HBV)-positive participants. We defined a recommended schedule as a vaccination series with at least six months between the two last doses and having three doses or more. We calculated weighted anti-HBs sero-prevalence for three anti-HBs levels: < 10 IU/L, 10-99 IU/L and ≥ 100 IU/L. We fitted two logistic regression models to examine the relationship between number of doses and recommended schedule on anti-HBs levels (≥ 10 IU/L and ≥ 100 IU/L) considering time since last dose and type of vaccine (Infanrix, Hexavac, Monovalent). RESULTS We included 2,489 participants. The weighted proportion of vaccinated children per anti-HBs level was < 10 IU/L: 36.3% [95%CI 34.0-38.7%], 10-99 IU/L: 35.7% [33.2-38.2%] and ≥ 100 IU/L: 28.0% [25.9-30.2%]. We did not find an association between a recommended schedule of three versus four doses and anti-HBs ≥ 10 IU/L or ≥ 100 IU/L. CONCLUSIONS Anti-HBs levels in later childhood were about equal, whether children received three or four doses. This implies that the change in the recommendations does not affect the anti-HBs level among children in Germany. Future studies are needed on the association of anti-HBs levels and adequate sustained protection against HBV.

Distribution and determinants of glycosylated hemoglobin in adolescents - Results from a nationwide population-based survey in Germany. PLoS One 2024; 19:e0296962. [PMID: 38386644 PMCID: PMC10883580 DOI: 10.1371/journal.pone.0296962] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 12/25/2023] [Indexed: 02/24/2024] Open
Abstract
The role of glycosylated hemoglobin (HbA1c) in youth is largely unclear. The aims of this study are to investigate the distribution and potential determinants of HbA1c among a population-based sample of adolescents. The German Health Interview and Examination Survey for Children and Adolescents (KiGGS) Wave 2 includes a nationwide representative sample of 0-17-year-old participants. For this evaluation, data from a randomly selected subgroup aged 14-17 years and without diagnosed diabetes was included (n = 857). Percentile-based HbA1c values (measured at laboratory in whole blood samples by high performance liquid chromatography) were calculated to examine HbA1c distribution. Multivariable linear regression analyses were performed to investigate factors (age, sex, parental socioeconomic status, body mass index (BMI), birth weight, smoking, alcohol consumption, healthy food diversity, sport activity, oral contraceptive use) associated with HbA1c. The mean HbA1c level was 5.2% (minimum: 3.9%, P10: 4.8%, P50: 5.1%, P90: 5.5%, maximum: 6.7%). Overall, 2.8% of adolescents had an HbA1c value in the prediabetic range (5.7-6.4%) and 0.1% had an undiagnosed diabetes (≥6.5%). Multivariable regression analysis showed an inverse association of age with HbA1c (17 vs. 14 years: ß: -1.18; 95% CI -2.05, -0.31). Higher HbA1c values were observed for higher BMI-standard deviation scores (SDS) (ß: 0.24; 95% CI -0.04, 0.52) and smoking (ß: 0.73; 95% CI -0.12, 1.57), but these tendencies were non-significant. In sex-stratified analysis, smoking and birth weight were significantly associated with HbA1c in boys. Among adolescents without diagnosed diabetes in Germany, HbA1c values ranged from 3.9% to 6.7%. To ensure health in adulthood, the influence of determinants on HbA1c levels in younger age should be further investigated.

Social Inequalities in Long-Term Health Effects After COVID-19-A Scoping Review. Int J Public Health 2024; 69:1606739. [PMID: 38384747 PMCID: PMC10878999 DOI: 10.3389/ijph.2024.1606739] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Accepted: 01/25/2024] [Indexed: 02/23/2024] Open
Abstract
Objectives: We aimed to map and synthesize evidence about social inequalities in long-term health effects after COVID-19 (LTHE), often referred to as "long COVID" or "post-COVID-19 conditions." Methods: We conducted a scoping review of peer-reviewed articles by searching the databases Embase and Scopus. According to predefined inclusion criteria, titles/abstracts and full texts were screened for eligibility. Additionally, reference lists of all included studies were hand-searched for eligible studies. This study followed the PRISMA guidelines for scoping reviews. Results: Nineteen articles were included. LTHE were analysed according to ethnicity, education, income, employment and deprivation indices. The studies varied significantly in their definitions of LTHE. Eighty-two analyses showed no statistically significant associations. At least 12 studies had a high risk of type II errors. Only studies associating deprivation indices and long COVID tended to show a higher prevalence of LTHE in deprived areas. Conclusion: Although some studies indicated social inequalities in LTHE, evidence was generally weak and inconclusive. Further studies with larger sample sizes specifically designed to detect social inequalities regarding LTHE are needed to inform future healthcare planning and public health policies.

Socioeconomic Differences in SARS-CoV-2 Infection and Vaccination in Germany: A Seroepidemiological Study After One Year of COVID-19 Vaccination Campaign. Int J Public Health 2023; 68:1606152. [PMID: 37780135 PMCID: PMC10538434 DOI: 10.3389/ijph.2023.1606152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2023] [Accepted: 09/04/2023] [Indexed: 10/03/2023] Open
Abstract
Objective: To evaluate the socioeconomic patterns of SARS-CoV-2 antigen contacts through infection, vaccination or both ("hybrid immunity") after 1 year of vaccination campaign. Methods: Data were derived from the German seroepidemiological Corona Monitoring Nationwide study (RKI-SOEP-2; n = 10,448; November 2021-February 2022). Combining serological and self-report data, we estimated adjusted prevalence ratios (PR) of SARS-CoV-2 infection, COVID-19 vaccination, basic immunization (at least two SARS-CoV-2 antigen contacts through vaccination and/or infection), and three antigen contacts by education and income. Results: Low-education groups had 1.35-times (95% CI 1.01-1.82) the risk of SARS-CoV-2 infection compared to high-education groups. COVID-19 vaccination (at least one dose) and basic immunization decreased with lower education and income. Low-education and low-income groups were less likely to have had at least three antigen contacts (PR low vs. high education: 0.74, 95% CI 0.65-0.84; PR low vs. high income: 0.66, 95% CI 0.57-0.77). Conclusion: The results suggest a lower level of protection against severe COVID-19 for individuals from low and medium socioeconomic groups. Pandemic response and vaccination campaigns should address the specific needs and barriers of these groups.

Long-term health consequences among individuals with SARS-CoV-2 infection compared to individuals without infection: results of the population-based cohort study CoMoLo Follow-up. BMC Public Health 2023; 23:1587. [PMID: 37605232 PMCID: PMC10440884 DOI: 10.1186/s12889-023-16524-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 08/14/2023] [Indexed: 08/23/2023] Open
Abstract
BACKGROUND Most of the previous studies on health sequelae of COVID-19 are uncontrolled cohorts and include a relatively short follow-up. This population-based multi-center cohort study examined health consequences among individuals about 1 to 1.5 years after SARS-CoV-2 infection compared with non-infected. METHODS The study population consisted of adults (≥ 18 years) from four municipalities particularly affected by the COVID-19 pandemic in the year 2020 who completed a detailed follow-up questionnaire on health-related topics. Exposure was the SARS-CoV-2 infection status (based on IgG antibodies, PCR test, or physician-diagnosis of COVID-19) at baseline (May to December 2020). Outcomes assessed at follow-up (October 2021 to January 2022; mean: 452 days) included recurrent or persistent health complaints, incident diseases, health-related quality of life (PROMIS-29), subjective health, and subjective memory impairment. Logistic and linear regression models were adjusted for baseline sociodemographic and lifestyle characteristics (age, sex, municipality, education, smoking, body mass index), pre-existing health conditions (chronic disease/health problem, health-related activity limitation, depressive/anxiety disorder), and follow-up time. RESULTS Among 4817 participants, 350 had a SARS-CoV-2 infection at baseline and 4467 had no infection at baseline or during follow-up. Those with an infection statistically significantly more often reported 7 out of 18 recurrent or persistent health complaints at follow-up: smell/taste disorders (12.8% vs. 3.4%, OR 4.11), shortness of breath (23.0% vs. 9.5%, 3.46), pain when breathing (4.7% vs. 1.9%, 2.36), fatigue (36.9% vs. 26.1%, 1.76), weakness in legs (12.8% vs. 7.8%, 1.93), myalgia/joint pain (21.9% vs. 15.1%, 1.53) and cough (30.8% vs. 24.8%, 1.34) and 3 out of 6 groups of incident diseases: liver/kidney (2.7% vs. 0.9%, 3.70), lung (3.2% vs. 1.1%, 3.50) and cardiovascular/metabolic (6.5% vs. 4.0%, 1.68) diseases. Those with an infection were significantly more likely to report poor subjective health (19.3% vs. 13.0%, 1.91), memory impairment (25.7% vs. 14.3%, 2.27), and worse mean scores on fatigue and physical function domains of PROMIS-29 than non-infected. CONCLUSION Even after more than one year, individuals with SARS-CoV-2 infection showed an increased risk of various health complaints, functional limitations, and worse subjective well-being, pointing toward profound health consequences of SARS-CoV-2 infection relevant for public health.

What is the health status of girls and boys in the COVID-19 pandemic? Selected results of the KIDA study. JOURNAL OF HEALTH MONITORING 2023; 8:39-56. [PMID: 37408715 PMCID: PMC10318563 DOI: 10.25646/11436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Accepted: 03/16/2023] [Indexed: 07/07/2023]
Abstract
Background It is well known that there are gender differences in the health behaviour and physical and mental health of children. The COVID-19 pandemic influenced the health and lifestyles of children and adolescents by changing their living conditions. The present work investigates whether gender differences in selected health indicators are evident more than two years after the onset of the pandemic. Methods In the study Kindergesundheit in Deutschland aktuell (KIDA) (German Children's Health Update), cross-sectional telephone surveys were conducted with parents of 3- to 15-year-olds (n=3,478). Parental information on the general and mental health of the child, on increased need for health care and mental health services, as well as on physical activity and utilisation of sports activities were queried in standardised manner. Gender differences were assessed using Chi2 tests. Results A total of 91% of the girls and 92% of the boys had their general health assessed as being (very) good by their parents (difference not significant, n.s.). An increased need for care and support was indicated for 10.6% of the 3- to 15-year-olds (girls: 9%, boys: 12%, n.s.). Boys met the physical activity recommendations of the WHO significantly more often (60%) than girls (54%). Good to excellent mental health was reported for 93% of both boys and girls. When changes during the pandemic were reported, no differences were found in the responses for girls compared to boys. Conclusions Gender differences were found for individual parameters and age groups. These differences must be assessed in the context of other social determinants of health, and need to be considered when planning preventive measures.

Nationally representative results on SARS-CoV-2 seroprevalence and testing in Germany at the end of 2020. Sci Rep 2022; 12:19492. [PMID: 36376417 PMCID: PMC9662125 DOI: 10.1038/s41598-022-23821-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Accepted: 11/07/2022] [Indexed: 11/16/2022] Open
Abstract
Pre-vaccine SARS-CoV-2 seroprevalence data from Germany are scarce outside hotspots, and socioeconomic disparities remained largely unexplored. The nationwide representative RKI-SOEP study (15,122 participants, 18-99 years, 54% women) investigated seroprevalence and testing in a supplementary wave of the Socio-Economic-Panel conducted predominantly in October-November 2020. Self-collected oral-nasal swabs were PCR-positive in 0.4% and Euroimmun anti-SARS-CoV-2-S1-IgG ELISA from dry-capillary-blood antibody-positive in 1.3% (95% CI 0.9-1.7%, population-weighted, corrected for sensitivity = 0.811, specificity = 0.997). Seroprevalence was 1.7% (95% CI 1.2-2.3%) when additionally correcting for antibody decay. Overall infection prevalence including self-reports was 2.1%. We estimate 45% (95% CI 21-60%) undetected cases and lower detection in socioeconomically deprived districts. Prior SARS-CoV-2 testing was reported by 18% from the lower educational group vs. 25% and 26% from the medium and high educational group (p < 0.001, global test over three categories). Symptom-triggered test frequency was similar across educational groups. Routine testing was more common in low-educated adults, whereas travel-related testing and testing after contact with infected persons was more common in highly educated groups. This countrywide very low pre-vaccine seroprevalence in Germany at the end of 2020 can serve to evaluate the containment strategy. Our findings on social disparities indicate improvement potential in pandemic planning for people in socially disadvantaged circumstances.

SARS-CoV-2 Seroprevalence in Germany: results from the second wave of the RKI-SOEP study. Eur J Public Health 2022.

Abstract
Abstract
Introduction
The first wave of the “Corona Monitoring bundesweit” (RKI-SOEP) study showed that shortly before the start of the German vaccination program only about 2% of adults (> 18 years) had already experienced SARS-CoV-2 infection and more than half of these cases had been detected and notified. The objectives of the second wave of this study are to further investigate the spread of SARS-CoV-2 in Germanýs population aged over 14 years. It aims to determine the seroprevalence of infection- and vaccine-induced IgG antibodies against SARS-CoV-2. Finally, it examines health, demographic and socioeconomic risk and protective factors for infection and vaccine acceptance.
Methods
From November 2021 to February 2022, the second wave of this cross-sectional study collected biospecimens (capillary blood samples) and interview data, including information on infection and vaccination, from a nationwide population sample drawn from the German Socio-Economic Panel (SOEP). The dried self-collected blood samples were then analyzed for the detection of SARS-CoV-2 IgG antibodies by Euroimmun ELISA assay.
Results
Based on preliminary, unweighted data of around 11,000 participants aged >14 years (52% response rate), we expect the final seroprevalence of SARS-CoV-2 antibodies to be in the range of 80 to 90%. Thus, around 10 to 20% of the German population may still be susceptible to a severe disease progression because they are neither infected nor vaccinated. Final results, weighted for non-response and adjusted for test sensitivity and specificity, will be presented.
Conclusions
The RKI-SOEP-2 study will be pivotal in both, contributing to an improved understanding of SARS-CoV-2 propagation in different regional and sub-group settings and in identifying vulnerable target groups that need to be protected against future infections.
Key messages
• Dried blood self-sampling in a nationwide sample is a robust tool to estimate seroprevalence at a population level.
• As of February 2022, presumably 80 to 90% of the German population has previously been infected and/or vaccinated against SARS-CoV-2.

Prevalence of Chlamydia trachomatis in the general population in Germany – a triangulation of data from two population-based health surveys and a laboratory sentinel system. BMC Public Health 2022; 22:1107. [PMID: 35659641 PMCID: PMC9164541 DOI: 10.1186/s12889-022-13456-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Accepted: 05/18/2022] [Indexed: 11/30/2022] Open
Abstract
Background Chlamydia trachomatis (chlamydia) is a common, frequently asymptomatic, sexually transmitted infection. It can result in severe sequelae, such as ectopic pregnancy and infertility. In Germany, chlamydia is not notifiable. An opportunistic screening program for women < 25 years was introduced in 2008. The aim of this research was to triangulate different data sources to describe the epidemiological situation of chlamydia in Germany and to investigate whether the current target group of the chlamydia screening program aligns with these findings. Methods Urine specimens from participants from population-based health examination surveys of children (2014–17) and adults (2008–11) were tested for chlamydia, using nucleic acid amplification testing. These data were used to generate weighted chlamydia prevalence estimates by age group and sex. Data from a nationwide chlamydia laboratory sentinel system (2014–16) were used to calculate the positive proportion among individuals tested for chlamydia by age, sex and test reason. Results Using data from the population-based surveys, we found a chlamydia prevalence estimate of 2.8% (95% confidence interval (CI) 1.0–7.5%) among all 15- to 17-year-old girls and of 9.6% (95% CI 0.0–23) among those reporting to be sexually active. In adult women, we found the highest prevalence among 18- to 24-year-olds (all: 2.3%; 95% CI 1.0–5.3%; sexually active: 3.1%; 95% CI 1.3–7.0%). In adult men, we found the highest prevalence among 25- to 29-year-olds (all: 3.5%; 95% CI 1.6–7.7%; sexually active: 3.3%; 95% CI 1.3–7.8%). Data from the chlamydia laboratory sentinel showed the highest positive proportion among those opportunistically screened in 19-year-old women (6.1%; 95%- CI 5.9–6.4%), among those screened due to pregnancy in 15-year-old girls (10%; 95% CI 8.5–12%), and among those tested due to symptoms or a positive partner in 19-year-old women (10%; 95% CI 9.8–11%) and 19-year-old men (24%; 95% CI 22–26%). Conclusions Chlamydia seems to mainly affect adolescents and young adults in Germany, with similar overall prevalence in men and women, but with slightly different age distributions. Women at highest risk of chlamydia are covered by the current screening program but given the on-going discussions in high-income countries on cost-effectiveness and benefit-to-harm ratio of these programs, the program-aim needs reconsideration.

Abstract
Background In Germany, HPV vaccination of adolescent girls was introduced in 2007. Nationally representative data on the distribution of vaccine-relevant HPV types in the pre-vaccination era are, however, only available for the adult population. To obtain data in children and adolescents, we assessed the prevalence and determinants of serological response to 16 different HPV types in a representative sample of 12,257 boys and girls aged 1–17 years living in Germany in 2003–2005. Methods Serum samples were tested for antibodies to nine mucosal and seven cutaneous HPV types. The samples had been collected during the nationally representative German Health Interview and Examination Survey for Children and Adolescents in 2003–2006. We calculated age- and gender-specific HPV seroprevalence. We used multivariable regression models to identify associations between demographic and behavioral characteristics and HPV seropositivity. Results We found low but non-zero seroprevalence for the majority of tested HPV types among children and adolescents in Germany. The overall seroprevalence of HPV-16 was 2.6%, with slightly higher values in adolescents. Seroprevalence of all mucosal types but HPV-6 ranged from 0.6% for HPV-33, to 6.4% for HPV-31 and did not differ by gender. We found high overall seroprevalence for HPV-6 with 24.8%. Cutaneous HPV type seroprevalence ranged from 4.0% for HPV-38 to 31.7% for HPV-1. In the majority of cutaneous types, seroprevalence did not differ between boys and girls, but increased sharply with age, (e.g., HPV-1 from 1.5% in 1–3-years-old to 45.1% in 10–11-years-old). Associations between behavioral factors and type-specific HPV prevalence were determined to be heterogeneous. Conclusions We report the first nationally representative data of naturally acquired HPV antibody reactivity in the pre-HPV-vaccination era among children and adolescents living in Germany. These data can be used as baseline estimates for evaluating the impact of the current HPV vaccination strategy targeting 9–14-years-old boys and girls.

Abstract
Hintergrund und Ziel Trotz niedriger Prävalenz der Hepatitis-B-Virus-(HBV-)Infektion in Deutschland ist es wichtig, vulnerable Gruppen und Ansatzpunkte für die Prävention zu identifizieren. In ersten Analysen der „Studie zur Gesundheit Erwachsener in Deutschland“ (DEGS1, 2008–2011) waren HBV-Infektion und -Impfung mit sozidemografischen Determinanten assoziiert. In dieser Arbeit werden die Ergebnisse im Detail untersucht. Material und Methoden In DEGS1 lag für 7046 Teilnehmende (Alter: 18–79 Jahre) eine HBV-Serologie vor. Die stattgehabte HBV-Infektion war durch Antikörper gegen das Hepatitis-B-Core-Antigen (Anti-HBc) definiert, die impfinduzierte Immunität durch alleinigen Nachweis von Antikörpern gegen das Hepatitis-B-Surface-Antigen (Anti-HBs). Seroprävalenzen von HBV-Infektions- und -Impfstatus wurden geschlechtsstratifiziert geschätzt und Assoziationen mit Alter, Gemeindegröße, Einkommen, formaler Bildung, Krankenversicherung und Migrationsgeneration in logistischen Regressionen analysiert. Ergebnisse Die HBV-Infektion war bei Männern und Frauen unabhängig mit den Altersgruppen 34–64 und ≥ 65 Jahre, erster Migrationsgeneration und Leben in größeren Gemeinden assoziiert, zudem bei Männern mit niedrigem Einkommen und bei Frauen mit niedriger Bildung. Die impfinduzierte Immunität war bei Männern und Frauen unabhängig mit den Altersgruppen 18–33 und 34–64 Jahre, mittlerer und hoher Bildung und hohem Einkommen assoziiert, darüber hinaus bei Männern mit mittlerem Einkommen und privater Krankenversicherung und bei Frauen mit fehlendem Migrationshintergrund. Diskussion Die Berücksichtigung von Migrationsstatus, Einkommen und Bildung könnte zur zielgenauen Ausrichtung der HBV-Prävention beitragen.

Abstract
Hintergrund SARS-CoV-2-Antikörperstudien ergänzen und erweitern die Erkenntnisse aus der Meldestatistik laborbestätigter COVID-19-Fälle um Informationen zu unentdeckten Fällen. Ziel der Arbeit Der vorliegende Beitrag fasst bisherige Ergebnisse zur SARS-CoV-2-Prävalenz aus seroepidemiologischen Studien in Deutschland zusammen, die sich auf Kinder und Jugendliche konzentrieren, und ergänzt die bereits vorliegende Übersicht zur Seroprävalenz bei Erwachsenen und speziell bei Blutspendenden in Deutschland. Material und Methoden Die Ergebnisse der Übersichtsarbeit beruhen auf einer fortlaufenden systematischen Recherche in Studienregistern, Literaturdatenbanken, von Preprint-Veröffentlichungen und Medienberichten seroepidemiologischer Studien in Deutschland sowie deren Ergebnissen. Ergebnisse Mit Stand 17.09.2021 sind uns 16 deutsche seroepidemiologische Studien, die sich auf Kinder und Jugendliche konzentrieren, bekannt geworden. Für 9 dieser Studien liegen Ergebnisse vor. Für fast alle untersuchten Settings lag die SARS-CoV-2-Seroprävalenz für Kinder im Kita- und Grundschulalter in der ersten COVID-19-Welle deutlich unter 1 % und für Jugendliche unter 2 %. Im Verlauf der Pandemie wurden höhere Seroprävalenzen von bis zu 8 % für Kinder im Grundschulalter ermittelt. Diskussion Ergebnisse von SARS-CoV-2-Antikörperstudien bei Kindern und Jugendlichen in Deutschland liegen bislang erst in geringem Umfang und basierend auf lokal-regionalen, nichtrepräsentativen Stichproben vor. In künftigen Studien gilt es, einerseits abzuschätzen, welcher Anteil der Kinder und Jugendlichen bereits eine Infektion hatte oder geimpft ist. Zum anderen gilt es, die Verbreitung körperlicher und psychischer Beeinträchtigungen im Nachgang einer Infektion zu untersuchen.

Abstract
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. FUNDING The Federal Ministry of Health, Germany.

Abstract
Since the beginning of the year 2020, the SARS-CoV-2 coronavirus has spread globally at a tremendous pace. Studies on the prevalence of SARS-CoV-2 antibodies in the population help estimate the number of people that have already been infected. They also allow an estimate of the number of undetected infections i.e. infections that do not appear in data on officially reported cases. The interpretation of study results needs to consider bias from selective sampling and the diagnostic test properties. To promote networking and co-operation between scientists, the Robert Koch Institute has compiled an overview of the seroepidemiological studies conducted in Germany on its website, which is regularly updated. The RKI conducts searches, for example of press releases, study registry entries or preprint server publications, and contacts the lead investigators of these studies. Of the 40 studies contacted so far, 24 have already provided information (as of 25.06.2020). We can differentiate between studies of the general population, of selected population groups such as healthcare workers, or of ongoing cohorts. This article provides an overview of such studies from Germany, but also of selected international studies. A special focus is set on studies of children and adolescents, which are now of particular interest due to the planned reopening of childcare facilities and schools.

The challenge of defining chronic illness for health monitoring in children: opening a can of worms. Eur J Public Health 2020.

Abstract
Abstract
Background
A straightforward health monitoring definition of chronic illness in children would have great utility for estimation of health care and social service needs as well as resource allocation.
Methods
This study analyses various definitions of chronic illness in children and adolescents in cross-sectional national health surveys in Germany based on: the Children with Special Health Care Needs (CSHCN) 14-item-questionnaire, a list of 15 self-reported medical diagnoses in the past 12 months, and a generic single-question parent-reported chronic condition from the Minimum European Health Module (MEHM), also used in EU-SILC and EHIS surveys.
Results
13.7% (95% CI 13.0-14.4) of children and adolescents aged 0-17 years had special health care needs in the first National Interview and Examination Survey in Children and Adolescents in Germany KiGGS 2003-2006. However, surprisingly, the prevalence was less than half in children with a migration background and was not associated with social status or income. The list of diagnoses identified a very high proportion of 31.5 (30.7-32.4) of children aged 0-17 years as chronically ill but does not take into account disease severity or impact. The generic MEHM-question in the KiGGS 2009-2012 survey identified 16.2% (15.3-17.1) of 0- to 17-year-olds as chronically ill, however, only one in five was affected in their daily activities. Parents denied chronic illness in 11.2% of children with epilepsy, 18.8% of children with asthma and 62.8% of children with attention deficit hyperactivity disorder.
Conclusions
None of the three definitions of chronically ill children is entirely satisfactory so far: CSHCN may need an adaptation of the German version to better capture inequalities, the disease list needs further severity differentiation and MEHM has recently shown low test-retest reliability (kappa 0.56) when administered twice within 6 months in a large Belgian sample and may need revisiting as well.

Abstract
Partnership, parenthood and employment constitute three main social roles that people adopt in middle adulthood. Against the background of the discussion about multiple roles and the reconciliation of family and work, this article analyses the association between the combination of social roles and self-rated health in Germany and the European Union (EU). The analysis is based on data from the second wave of the European Health Interview Survey (EHIS 2), which was conducted in all EU Member States between 2013 and 2015. The final sample included 62,111 women and 50,719 men aged between 25 and 59. Using logistic regression models, predictive margins for fair to very bad health in different family and employment constellations were calculated for the EU and Germany (in the case of men only for the EU in total). A difference was identified according to employment status in all family groups for women and men at the EU level: non-employed people rated their health as fair or bad more often, followed by part-time and full-time workers. Smaller differences by employment status were found for mothers with a partner in terms of the proportion of mothers who self-rated their health as bad compared to women in other family groups. No differences in health by employment status were found in Germany among mothers. This applies also to single parents. Different patterns of associations were identified between groups of EU Member States with diverse welfare systems.

Abstract
Trends of frequent chronic diseases and health problems, e.g. allergic diseases, have already been published based on the KiGGS Wave 2 study as part of the health monitoring of children and adolescents in Germany. The present work complements these findings with results on less frequent noncommunicable diseases and the trend of communicable, vaccine-preventable diseases.Information from parents about diagnoses and diseases of their 0‑ to 17-year-old children from the representative cross-sectional survey KiGGS Wave 2 (2014-2017) are compared with those from the KiGGS baseline survey (2003-2006) and KiGGS Wave 1 (2009-2012).The current KiGGS results show almost unchanged prevalences for the noncommunicable diseases epilepsy, migraine, and heart disease. However, the data from KiGGS Wave 2 are supportive of an increased prevalence of diabetes mellitus, which nevertheless continues to be relatively rare and predominantly type 1 diabetes in children and adolescents.The decline in measles, chicken pox, and whooping cough diseases related to changes in vaccination recommendations shows that preventive measures can effectively benefit children and adolescents.However, the data on vaccine-preventable diseases indicate regionally varying immunity gaps in certain age groups, so the prevention potential of the vaccination recommendations of the Standing Vaccination Commission (STIKO) at the Robert Koch Institute does not seem to have been sufficiently exploited.

Abstract
In KiGGS Wave 2, data from 3‑ to 17-year-olds were collected from a total of 3462 persons using a standardized interview on the current use of AM/NEM in the last seven days. For trends analysis, data from 14,679 study participants in the same age group from the KiGGS baseline study were used.In KiGGS Wave 2, 36.4% (95% CI 34.1-38.8) of the 3‑ to 17-year-olds had used at least one AM/NEM in the last seven days. The prevalence was highest at 46.5% in 14- to 17-year-olds and significantly different between girls and boys (56.4% vs. 37.3%). Only among girls were there significant differences by migrant background with a higher prevalence of use among girls without a migrant background.Most frequently, the preparations used were for treatment of the respiratory tract (girls: 14.2%, boys: 14.9%), followed by "Varia" (girls: 8.7%, boys: 9.3%) and preparations for the treatment of the musculoskeletal system (girls: 8.9%, boys: 5.8%). There was a significant decrease in the overall prevalence of medicine use compared to the KiGGS baseline study (46.4% vs. 36.4%). This decrease was mainly due to lower prevalences of use in the ATC main groups "N Nervous System" (7.5% vs. 5.4%), "J Systemic Anti-infectives" (2.5% vs. 1.4%) and "H Systemic Hormones, excl. Sexual Hormones and Insulins" (2.0% vs. 1.1%).The results describe key points in the use of AM/NEM, including self-medication for children and adolescents in Germany. They illustrate the use behaviour and represent a valuable supplement to prescription data.

Abstract
BACKGROUND Human Papillomavirus (HPV) vaccination of girls was introduced in Germany in 2007. However, data on the distribution of vaccine-relevant HPV types in the general population in Germany in the prevaccine era are limited. METHODS Serum samples collected during the German National Health Interview and Examination Survey 1998 (GNHIES98), a nationally representative study including men and women aged 18-79 years, were tested for antibodies to 19 mucosal and cutaneous HPV types. Multivariable regression models were developed to identify associations between demographic and behavioral characteristics and HPV seropositivity. RESULTS Of the 6517 serum samples tested, almost a quarter was seropositive for at least one of the nine HPV vaccine types with no clear age-pattern. HPV-6 and HPV-59 were the most common mucosal types, while HPV-1 and HPV-4 were the most common cutaneous HPV types. Factors independently associated with HPV-16 seroprevalence were seropositive to other sexually transmitted infections and lifetime number of sex partners, as well as urbanity (only among females). CONCLUSIONS Prevalence of naturally acquired antibodies to HPV types which can be prevented by vaccination is high in both sexes and all age groups. These data can serve as baseline estimates to evaluate the population-level impact of the current vaccination strategy.

Health inequalities among children and adolescents in Germany. Developments over time and trends from the KiGGS study. JOURNAL OF HEALTH MONITORING 2019; 4:15-37.

Abstract
This study examines the extent to which health inequalities among children and adolescents in Germany have developed over the past decade. The analyses are based on data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS), which are representative of the 0- to 17-year-old population in Germany. The KiGGS data were collected in three waves: the KiGGS baseline study (2003-2006), KiGGS Wave 1 (2009-2012) and KiGGS Wave 2 (2014-2017). Prevalences of five health outcomes are considered: general health, mental health problems, physical activity, the consumption of sugary soft drinks, and smoking. Moreover, it defines health inequalities in relation to differences in the socioeconomic status of the family (SES), an index derived from the parents’ level of education, occupation and income, and considers both absolute and relative health inequalities. In order to do so, the Slope Index of Inequality (SII) and the Relative Index of Inequality (RII) were calculated using linear probability or log-binomial models. Significant inequalities were identified to the detriment of young people from families with a low SES. These inequalities were particularly pronounced in the KiGGS Wave 2 data with regard to general health and the consumption of sugary soft drinks. Additionally, evidence from trend analyses for these two outcomes suggests that relative inequalities have increased. However, absolute inequalities decreased during the same period, and this also applies to smoking. The persistently high and, in some cases, widened levels of health inequalities indicate that adolescents from families with a low SES do not benefit to the same extent from disease prevention and health promotion measures for children and adolescents as young people from families with a higher SES.

Abstract
Since 2007, the Standing Committee on Vaccination (STIKO) has recommended that all girls receive vaccinations against the human papillomavirus (HPV) in order to reduce the disease burden of cervical cancer. Persistent infections with high-risk HPV subtypes increase a woman's risk of developing cancer. In the second wave of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2, 2014-2017), 42% of 2,958 11- to 17-year-old girls reported that they had received at least one HPV vaccination, and 31.4% reported a full HPV vaccination. 45.3% of 14- to 17-year-old girls reported a complete series of HPV vaccinations. Compared to the figures reported in KiGGS Wave 1 five years ago, HPV vaccination coverage has therefore remained stable. A vaccination coverage below 50% in girls is too low to exploit the potential of HPV vaccination to reduce cervical cancer rates in Germany.

Abstract
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.

Abstract
The close link between socioeconomic status (SES) and health can already be observed in childhood and adolescence. Although the vast majority of children and adolescents grow up healthily in Germany, social inequalities in health exist. The results of the second wave of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2) demonstrate that children and adolescents with a low SES have a poorer level of general health and face health constraints more frequently than their peers with a higher SES. Social inequalities in mental health are significantly more profound than in the 12-month prevalence of bronchial asthma and allergic rhinitis. The odds of being affected by mental health problems or attention-deficit/hyperactivity disorder (ADHD) were 2.8 to 4.4 times higher for children and adolescents with a low SES compared to their peers with a high SES. Therefore, in order to enable all children and adolescents to grow up healthily, health promotion and disease prevention measures need to be put in place early in a child's life and need to be tailored to the needs of particular target groups.

Abstract
Allergic diseases are among the most common health issues children and adolescents face. Allergic reactions occur when the immune system becomes allergically sensitised and are detected by measuring levels of specific immunoglobulin E antibodies (IgE antibodies) in the blood. This article discusses the prevalences of bronchial asthma, hay fever, atopic dermatitis and allergic contact dermatitis for 0- to 17-year-olds, as well as the prevalence of allergic sensitisation to a mix of frequent inhalant allergens (SX1) among 3- to 17-year-olds based on data from the second wave of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2, 2014-2017). 12-month prevalence trends between KiGGS Wave 2 and the KiGGS baseline study (2003-2006) are shown according to gender and age group. There were no significant changes in the 12-month prevalence of hay fever (8.8%) atopic dermatitis (7.0%) and bronchial asthma (3.5%) compared to the KiGGS baseline study, which indicates a stabilisation at a high level. More than one in six children (16.1%) currently suffer from at least one of these three diseases. 37.1% of 3- to 17-year-olds are sensitised to the multiple allergen mix SX1. Similar to the development of disease prevalence, SX1 sensitisation too has remained stable at a high level over the course of the past ten years.

Abstract
BACKGROUND Infection with cytomegalovirus (CMV) remains asymptomatic in most immunocompetent hosts, but is the leading cause of congenital viral infection worldwide and can be life-threatening in immunocompromised individuals. We aimed to assess CMV seroprevalence in a nationally representative sample of adults in Germany and to identify sociodemographic factors associated with CMV seropositivity. METHODS Blood samples from 6552 participants (18-79 years) of the "German National Health Interview and Examination Survey 1998", a population-based sample of the adult population in Germany, were tested for the presence of CMV antibodies using an Ig-multiplex assay. Weighted seroprevalence was calculated and weighted binomial regression was used to identify factors associated with CMV seropositivity. RESULTS Overall CMV seroprevalence was 56.7% (95%CI: 54.8-58.7%), with a higher seroprevalence in women (62.3%) than in men (51.0%). Seroprevalence increased with age: from 31.8% to 63.7% in men and from 44.1% to 77.6% in women when comparing the 18-29 with the 70-79 year age-group, respectively. CMV seroprevalence in women of childbearing age (18-45 years) was 51.7%. Factors significantly associated with CMV seropositivity were age, country of birth, smoking status, education, living in northern Germany and number of household members. In addition, having attended child care was associated with seropositivity in men, and number of siblings and living in East Germany in women. CONCLUSION Our results indicate that half the women of childbearing age were susceptible for primary CMV infection during pregnancy. CMV screening during pregnancy and informing seronegative women about CMV risk reduction measures could prevent congenital CMV infections with its serious consequences.

Abstract
The term 'subjective health' reflects not only existing illnesses and health complaints, but particularly emphasizes the personal well-being. Studies often collect data on subjective health by asking participants to provide self-assessments of their general state of health. This was also the case with GEDA 2014/2015-EHIS, which employed the internationally renowned Minimum European Health Module (MEHM) as part of the study. Its results demonstrate that 68.2% of adults in Germany rate their general health as very good or good, with the remaining 31.8% rating it as fair, poor or very poor. The proportion of women who rate their general health as very good or good is slightly lower than the proportion of men who do so (66.6% compared to 69.9%). With increasing age, women and men view the condition of their general health as worsening. The study also identified educational differences which showed that men and women with low levels of education tend to rate their health worse compared to self-assessments provided by women and men with higher levels of education, and in some cases also regional differences.

Abstract
Data from KiGGS Wave 2 show that 95.7% of parents who participated in the survey rated the overall health of their 3 to 17 year-old children as very good or good. This proportion is higher than the figures identified by the KiGGS baseline study across all age groups. The proportion of children rated as in very good health is highest among 3 to 6 year-olds and decreases with age. Among 14 to 17 year-olds, the proportion of girls in very good health is well below the level found among boys. A pronounced social gradient is still clear from the data: the proportion of parents who assess the overall health of their children as very good or good rises with increasing social status. This highlights the need for strategies to reduce health inequalities that involve society as a whole, and the need for target group-specific measures in prevention and health promotion.

Abstract
The incidence of chronic diseases in children has risen sharply throughout the world. Regardless of the particular diagnosis, chronically ill children and their families are faced with particular challenges. The transition to adulthood leads to changes in the conditions in which care is provided and the responsibilities that are associated with it. In this paper we used KiGGS cohort data to investigate the odds that chronically ill children and adolescents have of no longer feeling chronically ill or facing health impairments in young adulthood. Furthermore, it investigates the factors that are associated with an unfavourable transition from childhood into young adulthood. The analysis employs a data subgroup sourced from the first two waves of the KiGGS cohort - the longitudinal component of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) conducted by the Robert Koch Institute. The population-based KiGGS baseline survey was carried out between 2003 and 2006 as an examination and interview survey of 17,641 children and adolescents aged between 0 and 17. KiGGS Wave 1 - its first follow-up - was conducted between 2009 and 2012 via telephone. The KiGGS baseline survey used the German translation of the Children with Special Health Care Needs (CSHCN) screener as part of the written questionnaire provided to parents. This formed part of a generic approach towards identifying chronically ill children that applies irrespective of the diagnosis in question. KiGGS Wave 1 used a generic query to gather data on chronic illnesses using two questions taken from the Minimal European Health Module (MEHM); by this stage, the participants had reached adulthood. The information provided by 3,243 KiGGS cohort participants (who were aged between 18 and 24 at the time of KiGGS Wave 1) was analysed for indications of the presence or absence of a chronic disease among children and adolescents aged between 12 and 17. This was done using data gathered using the CSHCN screener between 2003 and 2006. Six years after the KiGGS baseline survey, half of the 509 participants who had screened positive (50.6%; 95% CI 44.4-56.8) stated that they were still chronically ill or faced health impairments. In contrast, one fifth of the participants who had provided no evidence of a chronic illness at the time of the KiGGS baseline survey (21.1%; 18.9-23.4) stated that they were now chronically ill or faced health impairments. Adolescents with a chronic illness reported being chronically ill in young adulthood more frequently than younger children (OR 1.8; 1.02-3.3). Bronchial asthma among 12- to 17-year-olds who had screened positive is associated with a reporting of chronic illness or health restrictions in later life (OR 3.5; 1.6-7.6). Regardless of age, obesity, the presence of asthma or an ADHD diagnosis, chronically ill boys who report pain, and chronically ill children from families with a low socio-economic status and few personal resources (personal protective factors), are at particular risk of a chronic illness in young adulthood.

Abstract
Seasonal influenza (flu) is an acute viral disease that occurs every winter in Germany and is referred to as the 'flu wave'. The Standing Committee on Vaccination (STIKO) at the Robert Koch Institute recommends annual vaccination for people who are at greater risk of disease-related complications, this includes men and women aged 60 or above. In this target group, 48.1% of women and 48.7% of men who participated in the GEDA 2014/2015-EHIS study reported that they had been vaccinated against influenza during the 2013/2014 winter season. However, there were marked differences according to region. Vaccination rates decreased over time. Moreover, although the European Commission has been calling for a vaccination rate of at least 75% among the elderly from the 2014/2015 influenza season onwards, it is unclear to what extent this rate can actually be achieved. However, rates can be improved by doctors providing advice and recommending vaccination to their patients.

Abstract
The fieldwork of the second follow-up to the German Health Interview and Examination Survey for Children and Adolescents (KiGGS) was completed in August 2017. KiGGS is part of the Robert Koch Institute's Federal Health Monitoring. The study consists of the KiGGS cross-sectional component (a nationally representative, periodic cross-sectional survey of children and adolescents aged between 0 and 17) and the KiGGS cohort (the follow-up into adulthood of participants who took part in the KiGGS baseline study). KiGGS collects data on health status, health-related behaviour, psychosocial risk and protective factors, health care and the living conditions of children and adolescents in Germany. The first interview and examination survey (the KiGGS baseline study; undertaken between 2003 and 2006; n=17,641; age range: 0-17) was carried out in a total of 167 sample points in Germany. Physical examinations, laboratory analyses of blood and urine samples and various physical tests were conducted with the participants and, in addition, all parents and participants aged 11 or above were interviewed. The first follow-up was conducted via telephone-based interviews (KiGGS Wave 1 2009-2012; n=11,992; age range: 6-24) and an additional sample was included (n=4,455; age range: 0-6). KiGGS Wave 2 (2014-2017) was conducted as an interview and examination survey and consisted of a new, nationwide, representative cross-sectional sample of 0- to 17-year-old children and adolescents in Germany, and the second KiGGS cohort follow-up. The completion of the cross-sectional component of KiGGS Wave 2 means that the health of children and adolescents in Germany can now be assessed using representative data gained from three study waves. Trends can therefore be analysed over a period stretching to over ten years now. As the data collected from participants of the KiGGS cohort can be individually linked across the various surveys, in-depth analyses can be conducted for a period ranging from childhood to young adulthood and developmental processes associated with physical and mental health and the associated risk and protective factors can be explored. As such, KiGGS Wave 2 expands the resources available to health reporting, as well as policy planning and research, with regard to assessing the health of children and adolescents in Germany.

Vaccinations in the first year of life and risk of atopic disease - Results from the KiGGS study. Vaccine 2017; 35:5156-5162.

Abstract
BACKGROUND The study focused on the question of whether and - if so - to what direction and extent immunisations in the 1st year may be associated with the risk of being diagnosed with atopic diseases after the 1st year of life. METHODS Data from the German Health Interview and Examination Survey for Children and Adolescents (KiGGS, 2003-2006) were analysed. For analyses of potential associations between vaccination status and risk of hay fever, atopic dermatitis or asthma, sample sizes of 15254, 14297, and 15262, respectively, were available. RESULTS Children with a sufficient TDPHiHeP vaccination at the end of the 1st year of life had a lower risk of being diagnosed with hay fever after the 1st year of life (adjusted prevalence ratio 0.85, 95% confidence interval 0.76-0.96). Analyses for associations between TDPHiHeP vaccination and risk of atopic dermatitis or asthma, or between age at onset of vaccination or of the number of antigens vaccinated in the 1st year of life and risk of atopic disease failed to yield statistical significance. CONCLUSIONS Our results provide no evidence that immunisations in the 1st year of life may increase the risk of atopic disease. If any association exists at all, our results may be interpreted as weakly supportive of the hypothesis that immunisations may slightly decrease the risk of atopy in later life.

Abstract
Background In 2004, universal childhood varicella vaccination was introduced in Germany. We aimed to determine the age-specific prevalence of anti-varicella zoster virus (VZV) IgG-antibodies among children in the pre-varicella vaccine era in Germany, to identify factors associated with VZV seropositivity, and to assess the suitability of a commercially available ELISA for VZV seroepidemiological studies by comparing it with an in-house fluorescent antibody to membrane antigen test (FAMA) as the gold standard. Methods Serum samples of 13,433 children and adolescents aged 1–17 years included in the population-based German Health Interview and Examination Survey for Children and Adolescents (KiGGS; conducted 2003–2006) were tested for anti-VZV IgG by ELISA. All samples with equivocal ELISA results and a random selection of ELISA-negative and -positive samples were tested by FAMA. Statistical analyses were conducted using a weighting factor adjusting the study population to the total population in Germany. Seroprevalences were calculated as percentages (%) with a 95% confidence interval (CI). Odds ratios (OR) were computed by multivariate logistic regression to determine the association between socio-demographic factors and VZV seropositivity. Results The VZV seropositivity rate was 80.3% (95% CI: 79.3–81.3) in varicella-unvaccinated children and adolescents. VZV seropositivity rates differed significantly between age groups up to age 6 years, but not by gender. Of 118 retested serum samples with an equivocal ELISA result, 45.8% were FAMA-positive. The proportion of samples tested as false-negative in by ELISA varied by age group: 2.6% in children aged 1–6 and 9% in children aged 7–17 years. Multivariate analyses showed that age, having older siblings, and early daycare start were associated with seropositivity in preschoolers; migration background reduced the chance of VZV seropositivity in schoolchildren (OR: 0.65; 0.43–0.99) and adolescents (OR: 0.62; 0.4–0.97). Conclusion In the pre-varicella vaccine era, most children in Germany contracted varicella by age six. Schoolchildren with a migration background and children without siblings have an increased risk of being VZV seronegative and should be targeted for catch-up vaccination, if they have no history of chickenpox. ELISAs are suitable for use in population-level serosurveys on VZV, but samples with equivocal ELISA results should be retested by FAMA.

Abstract
To estimate susceptibility to the swine-origin influenza A(H3N2) variant virus (A(H3N2)v) in the German population, we investigated cross-reactive antibodies against this virus and factors associated with seroprotective titre using sera from representative health examination surveys of children and adolescents (n = 815, 2003–06) and adults (n = 600, 2008–10). Antibodies were assessed by haemagglutination inhibition assay (HI); in our study an HI titre ≥ 40 was defined as seroprotective. We investigated associated factors by multivariable logistic regression. Overall, 41% (95% confidence interval (CI): 37–45) of children and adolescents and 39% (95% CI: 34–44) of adults had seroprotective titres. The proportion of people with seroprotective titre was lowest among children younger than 10 years (15%; 95% CI: 7–30) and highest among adults aged 18 to 29 years (59%; 95% CI: 49–67). Prior influenza vaccination was associated with higher odds of having seroprotective titre (odds ratio (OR) for children and adolescents: 3.4; 95% CI: 1.8–6.5; OR for adults: 2.4; 95% CI: 1.7–3.4). Young children showed the highest and young adults the lowest susceptibility to the A(H3N2)v virus. Our results suggest that initial exposure to circulating seasonal influenza viruses may predict long-term cross-reactivity that may be enhanced by seasonal influenza vaccination.

Abstract
BACKGROUND In Germany and worldwide, unintentional injuries (UI) are a major health threat for children and adolescents. The first follow-up of the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 1, 2009-2012) continued the national UI monitoring that started with the KiGGS baseline study (2003-2006). The present analysis provides updated information and for the first time gives indications on time trends. METHODS KiGGS Wave 1 is a combined nationwide cross-sectional and longitudinal survey by the Robert Koch Institute (RKI) providing information about 12,368 participating children and adolescents (0-17 years old; response rates: 38.8% first time invited, 72.9% reinvited). Parents were asked about their children's UI and poisonings via telephone interviews. Information on UI is available for 11,665 children and adolescents (1-17 years old). The 12-month prevalence rate and 95% confidence interval were calculated, and KiGGS Wave 1 was compared with the KiGGS baseline study. The Rao-Scott chi-square test corrected over the F distribution was used to test for the statistical significance of subgroup differences and trend effects. RESULTS Within the previous 12 months, 15.5% of all children and adolescents aged 1-17 years were medically treated for UI. UI were significantly more prevalent among boys (17.0%) than among girls (14.0%), and 3.4% of the subjects had more than one accident leading to UI. One in eight children and adolescents who suffered UI stayed in hospital (12.3%) for inpatient treatment for at least one night. The home, childcare and educational institutions, and sports facilities/playgrounds were the predominant accident locations. Compared to the baseline study, neither the overall prevalence of UI nor the gender- and age-specific patterns changed significantly. CONCLUSION Since a large proportion of UI is avoidable, knowledge of high-risk subgroups and accident locations is of particular use for prevention. KiGGS Wave 1 makes an important contribution to the comprehension of these issues. The transfer of research into practice is of particular importance for the avoidance of UI.

Abstract
Breastfeeding is the natural way of feeding infants in the first months of their lives and has been proven to have health benefits for both infants and mothers. Breastfeeding initiation and duration are affected by social, demographic and health factors. The aim of this study was to describe the current rates of breastfeeding initiation and duration in Germany, and to identify potential factors that underline these rates. Additionally, results are compared with the KiGGS basic (2003-2006; birth cohorts 1996-2002) study in order to reveal the development in the trends of breastfeeding initiation and duration in Germany. The KiGGS wave 1 (2009-2012) includes data on the breastfeeding behavior of mothers of 4410 children aged between 0 and 6 years (birth cohorts 2002-2012). Altogether, 82% (95% confidence interval 79.8-84.2 %) of children were ever breastfed, and the average breastfeeding duration was 7.5 months (7.2-7.8). There was a slight increase in the breastfeeding initiation in Germany over the last several years. Breastfeeding initiation among children aged 0-6 years increased by 4% points compared to 0- to 6-year-olds (birth cohorts 1996-2002) from the KiGGS basic study. The breastfeeding duration stayed unchanged. The breastfeeding behavior was mainly related to the age of the mother at birth, the mother's education level, smoking during pregnancy, and multiple or premature birth. Despite the overall increasing trend in breastfeeding initiation, there is still a growing need for breastfeeding promotion and support for young and less educated mothers, mothers who smoke during pregnancy, and also for mothers with premature babies or multiple births.

Abstract
In the absence of an immunisation register, vaccination coverage in Germany must be estimated. Ten years after the German National Health Interview and Examination Survey 1998 (GNHIES98), the population survey DEGS1 is one of the data sources to be used for monitoring vaccination coverage. In the survey, data on vaccination history were obtained from vaccination cards and self-reports. The prevalence of immunisation for tetanus and diphtheria was higher compared to the prevalence estimated ten years previously in GNHIES98. Nonetheless, 28.6 % of adults have not been vaccinated against tetanus and 42.9 % have not been vaccinated against diphtheria within the last ten years. Vaccination is especially low among the elderly, among adults with low socio-economic status and in western Germany. During the last ten years, only 11.8 % of women and 9.4 % of men were vaccinated against pertussis in western Germany; vaccination coverage was twice as high in eastern Germany. In 2009, recommendations were published to combine the next tetanus immunisation with a pertussis immunisation; therefore pertussis vaccination coverage might improve in the coming years. The lifetime prevalence of influenza vaccination obtained in DEGS1 is higher than the annual vaccination rate for influenza. However, the lifetime prevalence among adults aged 60 years or older is still below the annual rate of 75 % recommended by the WHO.

Abstract
Ten years after seroepidemiological data were obtained in the German National Health Interview and Examination Survey 1998 (GNHIES98), German Health Interview and Examination Survey (DEGS1) data contribute to a population-based, representative surveillance of hepatitis A and B immunity and of the serological markers for hepatitis C in Germany. The prevalence of antibodies against the hepatitis A virus is 48.6 %. In comparison to the situation 10 years ago, seroprevalence is significantly higher among 18- to 39-year-old adults and is significantly lower in those aged 50-79 years. The association between age and seroprevalence has changed, indicating a decrease in naturally acquired hepatitis A immunity. Individual and population immunity has to be achieved through vaccination. Prevalence of hepatitis B antibodies indicates that 5.1 % of adults have been exposed to the virus, significantly fewer than 10 years ago (7.9 %). Prevalence of hepatitis B surface antibodies indicates that 22.9 % of adults have been vaccinated against hepatitis B. Vaccination coverage has increased in all age groups and is highest in the younger age groups. These positive trends can be attributed to the general recommendation since 1995 to vaccinate against hepatitis B. For hepatitis C, the prevalence of antibodies in the general population is 0.3 %. Germany thus remains a low-HCV-endemic country. An English full-text version of this article is available at SpringerLink as supplemental.

Seroprevalence of measles-, mumps- and rubella-specific IgG antibodies in German children and adolescents and predictors for seronegativity. PLoS One 2012; 7:e42867.

Abstract
We have undertaken a seroprevalence study with more than 13,000 children, who had been included in the German KIGGS survey, a representative sample of children and adolescents 0-17 years of age. The IgG titres against measles, mumps and rubella were determined in 1 to 17 year olds While 88.8% of the children were MMR-vaccinated at least once, 76.8% of children aged 1 to 17 years showed prevalence of antibodies to MMR. The highest seronegativity was seen with respect to mumps. Gender differences were most pronounced with regard to rubella IgG titres: girls aged 14 to 17 years were best protected, although seronegativity in 6.8% of this vulnerable group still shows the need of improvement. Search for predictors of missing seroprevalence identified young age to be the most important predictor. Children living in the former West and children born outside of Germany had a higher risk of lacking protection against measles and rubella, while children with a migration background but born in Germany were less often seronegative to measles antibodies than their German contemporaries. An association of seronegativity and early vaccination was seen for measles but not for mumps and rubella. A high maternal educational level was associated with seronegativity to measles and rubella. In vaccinated children, seronegativity was highest for mumps and lowest for rubella. For mumps, high differences were observed for seronegativity after one-dose and two-dose vaccination, respectively. Seronegativity increases as time since last vaccination passes thus indicating significant waning effects for all three components of MMR.
