RESUMEN
Per- and polyfluoroalkyl substances (PFAS) are known as persistent and bioaccumulative chemicals. The present paper describes the analysis of 969 human blood samples collected in South Germany aiming to determine whether there are statistic significant differences in internal PFAS burden between three regions with known PFAS releases in the environment (study regions) and three regions without known PFAS releases in the environment (control regions). Nine environmental relevant PFAS were analyzed, including the perfluorooctanoic acid (PFOA) substitute 3H-perfluoro-3-[(3-methoxy-propoxy)propanoic acid] ammonium salt (ADONA). We found that concentrations of PFOA and perfluorooctane sulfonate (PFOS) were higher than for all other PFAS in all of the six regions, but all medians of PFOA (between 0.8 and 0.9 ng/ml for the study and control regions) and PFOS (between 1.3 and 1.5 ng/ml for the study regions and between 1.4 and 1.5 ng/ml for the control regions) were below the human biomonitoring values (HBM) I for PFOA (2 ng/ml) und for PFOS (5 ng/ml) derived by the German HBM Commission. Concentrations of ADONA were below the limit of quantification in all samples. Minor differences were observed in PFAS blood levels between study and control regions. Especially for PFOS and PFOA the medians for women are slightly lower compared to men. In summary, individuals living in regions with known environmental PFAS contaminations show no higher internal PFAS exposure to controls and in comparison to other studies in the literature.
RESUMEN
OBJECTIVE: To examine risky leisure noise exposure from listening to music via headphones and to identify potential determinants with special focus on portable listening devices (PLDs) among adolescents over a period of 7.5-years. DESIGN: Data were collected by questionnaires at four equidistant time points (O1-O4). Music exposure via headphones was calculated based on self-reported volume setting and listening duration. Exceeding 85 dB(A) equivalent for a 40-hour working week was defined as risky noise exposure. Determinants of risky headphone and PLD exposure were investigated using generalised estimating equations and accounting for missing data by multiple imputation. STUDY SAMPLE: Closed cohort of 2148 students attending 9th grade of any secondary school type in Regensburg (Germany), during 2009 to 2011. RESULTS: Risky noise exposure from headphone usage was almost twice as high in wave O1 and O2 (at age 15 or 18) compared with 20-23-year-olds in O3 and O4. Risky exposure to headphones and PLDs were associated with younger age, low and medium education, single-parent household and smoking, whereas good self-rated hearing showed a protective effect. Additionally, not being born in Germany was associated with risky PLD exposure. CONCLUSION: Before harmful behaviours become entrenched, starting preventive efforts at a young age is essential.
RESUMEN
OBJECTIVE: To observe total leisure noise (TLN) exposure and to investigate determinants of risky TLN exposure among adolescents and young adults over a ten-year observation period. DESIGN: OHRKAN is a longitudinal study with five equidistantly distributed questionnaires (waves) over ten years. Risky TLN exposure was defined as exceeding ≥85dB(A) averaged over 40h per week. To identify determinants of risky TLN exposure longitudinally, generalised estimating equations were applied. STUDY SAMPLE: A subgroup (n = 661; mean age 25.6 years in the fifth wave; 58.4% female) of the closed cohort study OHRKAN was analysed. Included participants took part in the fifth wave prior to the study break due to COVID-19. RESULTS: Analysis of participants' data from all five waves showed that risky TLN exposure was highest during the second wave (72.0%), when participants were aged 17-19 years, and thereafter steadily declined. Among young adults, attendance at discotheques and private parties, especially, caused very high exposure. Determinants of risky TLN exposure were wave time point, male gender, a higher level of education, and smoking. CONCLUSIONS: As TLN exposure is highest among older adolescents, prevention programs should target younger teenagers and be tailored to the identified risk groups. The risk from private parties should be addressed.
RESUMEN
OBJECTIVE: The overall objective in the study was to compare self-reported hearing based on a single question ("how good would you currently rate your hearing?") to measure hearing loss determined by audiometry in a cohort of adolescents. Prevalence of audiometrically measured hearing loss and frequencies of self-reported poor hearing as well as factors that have an impact on self-reported hearing were examined. DESIGN: Baseline and 5-year follow-up data of the Ohrkan study were used. Participants filled in a questionnaire and underwent audiometric measurements. STUDY SAMPLE: Data from 979 adolescents were analysed. Participants were 54.7% female and aged between 13 and 18 years at baseline and 17-21 years at 5-yr follow-up. RESULTS: The single question on self-reported hearing ability achieved a sensitivity of 41.9% and a positive predictive value of 7.1% at baseline. For the 5-yr follow-up, sensitivity was 40.0%, positive predictive value was 13.9%. Factors influencing self-reported poor hearing were gender, tinnitus, "muffled" ears after exposure to loud noise (e.g. after a concert) and low-frequency hearing loss. CONCLUSIONS: The single question about hearing ability used in the Ohrkan study is not sufficient to replace audiometry to detect hearing loss as defined in the study in adolescents.

Due to the SARS-CoV-2 pandemic, healthcare workers worldwide faced major challenges in the form of psychological stress. The aim of this systematic literature review and meta-analysis is to identify mental health consequences and associated work-related factors in healthcare workers during a pandemic and to quantify the influence of associated work-related factors on mental health consequences. A systematic literature search according to PRISMA was conducted on 5 August 2021 using the databases PubMed Central and APA PsychInfo. The included studies investigated the mental health consequences and associated work-related factors in healthcare workers in a pandemic. In addition, we performed a risk of bias analysis to assess the study quality of the included studies using the JBI checklists. Random-effect models and pooled effect estimators were used for the meta-analysis. The Chi2 and I2 statistics were used to identify the statistical heterogeneity. Additional sensitivity analysis was performed. From a total of 3,910 publications, 43 studies met the inclusion criteria. These studies provided 15 stress consequences and 20 stress factors. The most frequently reported stress factors were 'contact with COVID-19 patients', 'no education or training in handling infectious diseases' and 'insufficient protective equipment'. Anxiety, stress, and depression were the most common outcomes identified. Analyses showed an increase in anxiety scores among HCWs who cared for COVID-19 patients, as well as a rise in depressive symptoms due to inadequate or no personal protective equipment. In this review, various pandemic-associated stress factors and stress consequences of healthcare workers were observed. With the results, criteria for effective measures and interventions can be developed to minimize the risk of stress consequences.

People can be affected by various environmental factors (e. g., odor, noise) which can lead to medical complaints or illnesses. Few adequate contact points are available for patients with suspected environmental complaints in Germany. Illustrated by the outpatient clinics for environmental medicine in Hamburg and Munich, this report shows how patients with suspected environmental medical diseases are cared for in Germany. For the exemplary presentation, the data of the environmental medicine outpatient clinics of both the university hospitals from 01.01.2019 to 31.03.2021 are presented and compared. Overall, more female than male patients were treated at both facilities. Suspected exposure to "heavy metals" was most frequently mentioned by patients as the assumed reason for their complaints. Nonetheless, the suspected exposure or "intoxication" could be ruled out in the majority of cases by appropriate examination methods in accordance to current medical guidelines. The data provided by the environmental medicine outpatient clinics show that there is a continuous demand for environmental medical care. A close cooperation between the private practice sector and the outpatient clinics for environmental medicine providing medical care to patients should therefore be sought.

BACKGROUND: Allergic diseases pose a health problem worldwide. Pollen are widespread aeroallergens which can cause symptoms like shortness of breath, cough, itchy eyes, or rhinitis. Apart from preventive measures and pharmacological treatment, also non-pharmacological interventions have been suggested to reduce symptoms. The objective of this work was to review studies investigating the effectiveness of non-pharmacologic interventions to reduce allergic symptoms. METHODS: PubMed, EMBASE, and CENTRAL were systematically reviewed in July 2018 and April 2020. Several authors worked on the screening of titles, abstracts, and full texts. One author for each literature search performed the data extraction and the risk of bias assessment. Studies were included if they met the inclusion criteria defined by the PECOs. Studies which investigating the effect of non-pharmacologic interventions on patients with allergic rhinitis were included. RESULTS: Twenty-nine studies investigating eleven types of non-pharmacologic interventions to avoid and reduce allergic symptoms due to pollen exposure were included in this review. Out of all studies, seven studies addressed nasal rinsing and 22 included acupuncture, air filtering, artisanal tears, individual allergen avoidance advice, various nasal applications, self-hypnosis, rhinophototherapy, and wraparound sunglasses. CONCLUSION: Most studies had a high risk of bias and small sample sizes. There were only a few high-quality studies that give hints about the effectiveness of non-pharmacological interventions. For future research, more high-quality studies are required to confirm the effectiveness of simple, safe, and cost-effective interventions.

Introduction: Asthma is among the most common chronic conditions in children. The aim of this publication is to describe prevalence rates and factors associated with asthmatic or wheezing preschoolers and to evaluate medical care and treatment with regard to urban-rural differences.Methods: Data for this cross-sectional study were collected through a questionnaire, which was distributed to parents within the Health Monitoring Units in Bavaria (HMU), Germany. Data from 4767 children were available (2016/17). Those children were classified into four diagnostic groups: Unremitting Wheeze, International Study of Asthma and Allergies in Children (ISAAC) Asthma, Physician-diagnosed Asthma, and healthy control group. Urban-rural differences were tested by Pearson's chi-squared test or by Fisher's exact test. Independent variables were factors associated with health outcomes, for example, residency or migrant status. To examine associations between independent and outcome variables multivariate logistic regression analysis was performed.Results: Prevalence rates were 6.3% for 'Unremitting Wheeze', 5.2% for 'ISAAC Asthma', and 1.2% for 'Physician-diagnosed Asthma'. Factors associated with health outcomes were the occurrence of asthma in first-degree relatives, male sex, and migrant status. Generally, higher rates of doctor's visits, positive allergy tests, and corticosteroids intake in the diagnostic groups in rural compared to urban areas were observed. Rates of performed allergy tests were 55.6% for 'ISAAC Asthma' and 74.6% for 'Physician-diagnosed Asthma'.Conclusions: Prevalence rates of the diagnostic groups decreased compared to the HMU 2014/15. According to previous studies, factors associated with asthmatic or wheezing health outcomes could be confirmed. Children in rural areas generally received more medical care.Key pointsChildren's prevalence rates of asthma or wheezing disorders decreased in the past 2 years within Bavaria.This study is consistent with risk factors for asthma from the literature: asthma in the family, male gender, and migrant status.Children in rural areas receive more medical care than children in urban areas.There should me more allergy tests among children with medical diagnosis in Bavaria as low rates indicate gaps in care.

Abandoned gold mining spoils pose socio-environmental, human, and animal health impacts and threaten sustainability of mineral extraction. Green trials and ecological solutions are required to effectively remediate these contaminated soils and mitigate the associated risks. Here, we carried out a pot experiment using a highly contaminated soil (mean total As = 5104.0 mg/kg) collected from an abandoned mine spoil in Ghana. We aimed to quantify the impacts of compost, iron oxide, and poultry manure on the mobilization, fractionation, and uptake of As by ryegrass (Lolium perenne). The soil amendments were applied at a rate of 5% (w/w) each, separately or in combination. We extracted the mine spoil soil readily-bioavailable As and specific-sorbed As, and determined the As contents in plant and the uptake after harvest. The plant transfer indices for soil-to-root (bioconcentration factor, BCF), soil-to-shoot (bioaccumulation concentration- BAC), and root-to-shoot (translocation factor- TF) were also calculated. Addition of manure increased the mining readily-bioavailable As by 243% and specific-sorbed As by 38%, as compared to the control. Manure addition further aided root As-uptake by 134%, whilst its combination with compost increased uptake by 101%. Lone addition of manure and in combination with compost resulted in BCF above 1, indicating increased As-phytostability. The presence of carbon and iron in the roots of the ryegrass sorbed or precipitated As limited its soil-to-shoot and root-to-shoot transfer. These findings indicate that manure alone and in combination with compost can be used to augment the phytoremediation efficiency of ryegrass in the As-contaminated spoil.

OBJECTIVES: To investigate the association between total leisure noise exposure and intermittent tinnitus among young adults. DESIGN: Data were obtained from the Ohrkan study, an ongoing prospective cohort study conducted in South Germany since 2009. Information about exposure to impulse and leisure noise, tinnitus occurrences, sociodemographic variables, and self-rated hearing ability were analysed at four time points over a period of seven and a half years. STUDY SAMPLE: Participants of the Ohrkan cohort study, who provided data about the occurrence of tinnitus for all surveys (n = 1028). RESULTS: Intermittent tinnitus was reported in the majority of the sample (60%). The risk for intermittent tinnitus increased with higher sound pressure levels from exposure to leisure noise (full model (Odds Ratio, 95%CI): 80-<85dB(A): 1.41 [1.13-1.78], 85-<90dB(A): 1.73 [1.38-2.16], >90dB(A): 2.04 [1.59-2.61]). Visiting nightclubs was a major contributor to this relationship. Of the considered covariables, self-rated hearing as "poor", and growing up in a single-parent household were significantly associated with intermittent tinnitus. CONCLUSION: Intermittent tinnitus is very frequent among young adults and is associated with high levels of leisure noise exposure. To prevent intermittent tinnitus, reduced sound pressure levels and the use of hearing protection are necessary.

OBJECTIVE: Investigating determinants of total leisure noise (TLN) exposure among adolescents over 7.5 years and compensating for missing data due to loss to follow-up. DESIGN: In the OHRKAN cohort study, data were collected by questionnaires at four waves. TLN was calculated from self-reported duration spent participating in 18 leisure activities. High exposure was defined as exceeding 85 dB(A) of equivalent continuous average sound pressure level (SPL) during a 40-h week. Multiple imputation (MI) and generalised estimating equations (GEE) were used to analyse odds ratios (OR) of determinants of TLN exposure and compared to complete-case analysis. STUDY SAMPLE: Closed cohort of 2148 students enrolled in grade 9 of any school in Regensburg (Germany), recruited from 2009 to 2011. RESULTS: Up to 74% of adolescents had risky TLN exposure, depending on wave. The most significant sources were discotheques, portable listening devices (PLD) and stereo systems. Higher TLN exposure was associated with time point, education, single-parent households and gender. MI under MAR assumption changed results only slightly compared to complete-case analysis. CONCLUSIONS: Prevalence of risky TLN is high during adolescence. MI reinforced trends detected in former results of OHRKAN. Preventive measures should consider the main drivers of noise exposure including changes by age and high risks groups.

OBJECTIVE: The aims of this work were the systematic and evidence-based generation and answering of frequently asked questions (FAQ) regarding contact with multi-drug resistant pathogens (MDR) including aspects of veterinary and human medicine for the public health service (PHS) and the general population. METHODS: In order to determine the information needs of the population, guideline-based expert interviews with veterinarians and physicians were conducted in five surveys. In addition, information about the project was published in two journals and the participants were asked to submit open questions from their daily routine with respect to MDR. The results of the interviews and project calls were divided into categories, and frequently mentioned topics were prepared as FAQ. For answering the FAQ, a systematic literature search in the databases Pubmed and Wiley Online Library was conducted. A panel of experts subsequently evaluated the FAQ drafts, and a consensus was reached in case of conflicting results. Thereafter, the FAQs were evaluated by physicians and veterinarians of the PHS. RESULTS: Nine FAQs were generated in total. In addition to a survey of the current state of research, recommendations were made for private dealing with non-medical contact with MDR at the interface of human and veterinary medicine. The recommendations depended on the respective setting and the type of animal contact. Different recommendations were given for the handling of MDR in pets, farm animals, animals in communal facilities and animals used for animal-assisted therapies. The most important measure against the spread of MDR between humans and animals proved to be regular and careful handwashing. CONCLUSION: Mixed methods were used to ensure the quality of the FAQ. Limitations were found in the literature search. Not all submitted questions could be answered with the available literature. In the future, the FAQ should be continuously updated and extended.

BACKGROUND: Concerns about smoking displacement from public places to private amenities aroused following smoking ban implementation in Bavaria in 2008. We analysed children's exposure to second-hand smoke (SHS) before and after the ban, its effect on children's health and prevalence of active smoking in adults. METHODS: Six cross-sectional surveys (n = 32,443) on pre-school children in Bavaria were analysed, two surveys before the smoking ban in years 2004 and 2005 (S1 and S2) and four after the ban in 2008, 2012, 2014 and 2016 (S4, S6, S7 and S8). Using multivariable logistic regression, we analysed change in children's intra- and extrauterine SHS exposure and its adverse health effects (Asthma, wheezing, bronchitis and neurodermatitis) as well as change in parental active smoking. RESULTS: The response rates were 78% for S1, 73% for S2, 61% for S4, 62% for S6, 56% for S7 and 54% for S8. Odds of parents never smoked at home in presence of children increased significantly from before to after the ban with odds ratios (OR) 1.17 (CI95% 1.01-1.35), 1.65 (CI95% 1.39-1.95), 2.85 (CI95% 2.32-3.51), 2.24 (CI95% 1.84-2.72) and 3.66 (CI95% 2.89-4.63) for S2, S4, S6, S7 and S8, respectively with S1 as reference. Compared to S4, odds of parents who were not actively smoking is significantly higher in S7 (OR = 1.13 (CI95% 1.03-1.24)) and S8 (OR = 1.24 (CI95% 1.13-1.36)). The odds of mothers who never smoked during pregnancy increased over time with OR = 1.22 (CI95% 1.06-1.40) for S2 and 1.57 (CI95% 1.33-1.86) for S8 compared to S1. Adverse health effects related to children's exposure to SHS are significantly less in S8 compared to S1. CONCLUSION: After 11 years of smoking ban in Bavaria, smoking displacement to homes was disproved. Exposure of children to SHS intrauterine and at home is decreasing. Number of parents who are not actively smoking is increasing over time. Prevalence of health problems in children related to exposure to SHS is decreasing.

BACKGROUND: Atopic diseases are among the most common chronic conditions in childhood. Causes of allergies are manifold. The aim of this paper is to evaluate risk factors for atopic diseases and unremitting wheeze and to examine if there is an association between measles, mumps and rubella (MMR) vaccination and atopic dermatitis, asthma and unremitting wheeze in Bavarian pre-schoolers. METHODS: Parents filled out a questionnaire on children's health and environmental and socioeconomic factors. The questionnaire was administered within the Health Monitoring Units in a cross-sectional study in Bavaria, Germany (2014/2015). Data on vaccinations were obtained via the School Entrance Examination, a mandatory examination for pre-school children in Bavaria. Rates of influential factors of atopic diseases and wheeze, MMR and DTP (diphtheria, pertussis and tetanus) vaccination were calculated for all children stratified by health outcomes. To examine if there is an association between MMR vaccination and health outcomes, a multiple logistic regression analysis was performed. RESULTS: Data were available for 3237 individuals. Symptoms and diseases were more frequent in boys. Higher parental education was associated with a higher prevalence of atopic dermatitis. There were no significant associations between any of the health outcome groups and MMR vaccination in the multiple logistic regression models with adjustment for potential confounders. CONCLUSIONS: The present study is in line with the current state of research that MMR vaccination is not associated with atopic diseases.

BACKGROUND AND AIM OF THE STUDY: The loss of participants during the follow-up of cohort studies can introduce bias if persons who leave the study differ from those who continue to participate over time. Many studies have investigated socio-demographic and health factors associated with participation/non-participation in epidemiological studies. However, relatively few studies are available for school-based cohorts. The aim of this study was to determine predictors of willingness to participate in the Ohrkan study, an ongoing longitudinal survey of adolescents that collects detailed information on leisure time noise exposure and potential effects on hearing. METHODS: Using the Ohrkan cohort of 2,148 persons recruited in 2009-2011 (O-I) among the ninth graders of any secondary school type in Regensburg and followed-up in 2012-14 (O-II) and 2015-16 (O-III). RESULTS: The probability of participating in O-II and O-III was higher for persons without a migration background, who attended university-preparatory secondary school at baseline and whose parents had a higher educational level or lived together. Persons who had not changed their place of residence in the last 2.5 years also participated 3 times as often as respondents who moved inside or outside of Regensburg. CONCLUSION: The knowledge of determinants of attrition and retention makes it easier to specify which groups of a cohort are most likely to be lost to follow-up. These groups can be targeted in order to minimize their loss in the future follow-ups. Moreover, the predictors can be used in statistical missing data techniques such as multiple imputation.

There is high demand for online, real-time and high-quality pollen data. To the moment pollen monitoring has been done manually by highly specialized experts. Here we evaluate the electronic Pollen Information Network (ePIN) comprising 8 automatic BAA500 pollen monitors in Bavaria, Germany. Automatic BAA500 and manual Hirst-type pollen traps were run simultaneously at the same locations for one pollen season. Classifications by BAA500 were checked by experts in pollen identification, which is traditionally considered to be the "gold standard" for pollen monitoring. BAA500 had a multiclass accuracy of over 90%. Correct identification of any individual pollen taxa was always >85%, except for Populus (73%) and Alnus (64%). The BAA500 was more precise than the manual method, with less discrepancies between determinations by pairs of automatic pollen monitors than between pairs of humans. The BAA500 was online for 97% of the time. There was a significant correlation of 0.84 between airborne pollen concentrations from the BAA500 and Hirst-type pollen traps. Due to the lack of calibration samples it is unknown which instrument gives the true concentration. The automatic BAA500 network delivered pollen data rapidly (3 h delay with real-time), reliably and online. We consider the ability to retrospectively check the accuracy of the reported classification essential for any automatic system.

BACKGROUND: Within the last decades the world of work has changed enormously. Due to new Information and Communication Technologies (ICT), working at any time from any place has become possible. Flexibility, availability and the dissolution of boundaries between work and private life are the possible results of this development. The spread of this development and possible consequences on the affected employee's health and wellbeing have been examined so far especially in big companies. Small and medium-sized enterprises (SME) are rarely subjects of scientific studies in this context. OBJECTIVE OF THIS PAPER: The aim of this work was to develop a guideline based on experiences and results of a study regarding flexibility in the business world (FlexA), as well as a systematic literature research. The target populations of this guideline are SMEs, focusing on integrating a health promoting way in dealing with ICT, flexibility and availability within the corporate culture. METHODS: In order to delineate the current state in of research in ICT-related work interventions, a systematic review in data bases e. g. PsycINFO, EconLit and Medline was carried out. The search strategy used the key words "work", "intervention", "ICT", "mental strain", "flexibility" and "availability". In addition, grey literature and findings from the FlexA study were used to formulate the current guideline. RESULTS: Based on the exclusion criteria, all studies from the systematic literature search were excluded after title and abstract screening. Within grey literature research, 4 relevant publications could be identified. The measures, developed during the corporate workshops of the FlexA study, e. g. the implementation of collective regulations in the company, were included in the guideline. CONCLUSION: Due to the ongoing development of ICT and flexibility in daily business life, it is getting more and more important to follow this progress. Executives and corporate management are responsible to actively shape this trend in a health-promoting way in their enterprises. The current guideline was made to support the corporate management in this task and it is an important instrument for a health-promoting use of ICT in daily business life taking in to consideration flexibility and availability.

The aim was to investigate leisure noise exposure and sociodemographic determinants of risky leisure noise exposure over five years in 2148 students visiting grade 9 of any school type in a German city from 2009-2011. Within the OHRKAN cohort study, leisure noise exposure was calculated from literature-retrieved sound pressure levels (SPLs) and self-reported duration of 18 leisure activities at baseline and two follow-ups. Risky exposure was defined as exceeding 85 dB(A) averaged over a 40-h-week. Determinants of risky total leisure noise (TLN) exposure and risky exposure to portable listening devices (PLDs) were investigated using generalised estimating equations (GEEs). Up to 73% of students exceeded noise levels of 85 dB(A) at some timepoint. The noise exposure and importance of different leisure activities changed with increasing age. Risky exposure to TLN and PLDs was associated with lower education, single parent households and being male. Risky PLD exposure was additionally associated with a migrant background. Current prevention measures for leisure noise exposure must be extended to at-risk groups. Besides enhancing campaigns in lower education schools, acoustical insulation in sports halls, noise warnings on tools or in videogames could address especially men. Migrants need education about healthy PLD use in their native language if necessary.

Our environment is a major factor in determining health and well-being throughout life, from conception into old age. This overview illustrates the most important epidemiological studies and health monitoring systems in Germany, which investigate environmental influences in various population subgroups and estimate related health effects. Environmental factors examined in each study are described. The mentioned studies in children and adults build the basis for predictions and preventive measures. The number of the assessed environmental factors, the depth of the examinations as well as the (phenotypical) characterization of the study participants differ. Still, the obtained data build a base for important future research. However, for this, a permanent and Germany-wide assessment of environmental factors is necessary.The proportion of the European population living in urban areas is projected to increase in the future. Therefore, environmental factors such as air pollution, air temperature, and noise, but also social inequality, are likely to have a negative effect on health and quality of life of the population. The challenge of the aging population as well as potential adaptation processes to the diverse environmental stimuli requires multidisciplinary approaches. From an environmental epidemiology view, the collected data from the described studies are of immense value because only with this data can associations between environment and health be investigated and public health-relevant preventive measures be identified.The NAKO health study will be the largest resource of health data and should therefore be included in future activities related to the investigation of environmental health effects in Germany.
