The development of working life expectancy without musculoskeletal diseases against the backdrop of extended working lives.

Musculoskeletal diseases (MSDs) are a major predictor of early retirement. Against the backdrop of the extension of working life, we investigated time trends and educational inequalities in years spent in the labour market free of MSD. Based on German statutory health insurance data (N = 3,405,673), total life years free of MSD (Healthy Life Expectancy, HLE) and years spent in the labour force free of MSD (Healthy Working Life Expectancy, HWLE) were estimated for three periods (2006-2008, 2011-2013, 2016-2018) using multistate analyses. Educational inequalities (8 to 11 vs. 12 or more years of schooling) are reported for 2011-2013. HLE decreased slightly over time in all genders. HWLE in women increased, while it remained rather constant in men. Over time, the share of years in the labour force spent free of MSD declined continuously. People with lower education had lower HLE and HWLE than individuals with higher education. With respect to musculoskeletal diseases, the increase in disease-free working life years cannot keep pace with the extension of working life, resulting in an increasing proportion of years spent in impaired musculoskeletal health in the labour market. Effective prevention strategies are needed, focusing especially on individuals with lower educational attainment.

Impact of sitting at work on musculoskeletal complaints of German workers - results from the study on mental health at work (S-MGA).

INTRODUCTION: Sedentary behavior (including prolonged sitting) is a form of physical inactivity that has a negative impact on health, possibly including musculoskeletal complaints (MSCs). The purpose of this study was to determine the extent to which time spent sitting at work is associated with the one-year prevalence of MSCs in the neck, shoulder, upper back/thoracic spine, and lower back among workers from the Study of Mental Health in the Workplace (S-MGA). In addition, the study also examined whether leisure time, physical activity, and sex modify the relationship between occupational sitting and MSCs. METHODS: For this analysis, we used the S-MGA, a 5-year prospective study in Germany. The S-MGA is a nationwide representative employee cohort study with a baseline survey in 2012 and a follow-up survey in 2017. Sitting at work was measured using a question asked at baseline. The Nordic Musculoskeletal Questionnaire was used to determine the one-year prevalence of MSCs in the neck, shoulder, upper back, and lower back pain (yes/no). The assessment of MSCs was only conducted at the 2017 follow-up. Adjusted Poisson regression models were used to determine the association of baseline level of weekly hours spent sitting at work with MSCs during follow-up. In addition to unadjusted models, models were adjusted for demographic (age, sex, body mass index and occupational skill level), occupational (heavy lifting at work), psychological disorders and lifestyle factors (smoking status and leisure time physical activity), as well as preexisting musculoskeletal conditions reported at baseline. To examine whether the relationship between sitting time and pain was modified by sex and leisure time physical activity, the models were stratified for both these variables. RESULTS: Among the participants analyzed (n = 2,082), 49.8% were male, while 50.2% were female, and more than 60% of the study population spent over half of their working hours in a sitting position. Exposure to increased sitting at work reported at baseline was not consistently associated with 12-month prevalence of MSCs in the upper body at follow-up. However, differences in the association between occupational sitting and MSCs were dependent on the intensity of leisure time physical activity. Prevalence ratios (PRs) indicated an increased prevalence of MSC in the neck (PR = 1.46; 95% CI = 1.18-1.80) and shoulder (PR = 1.30; 95% CI = 1.03-1.64) in workers without leisure time physical activity who spent 25 to < 35 weekly working hours sitting. DISCUSSION: These findings suggest that leisure time physical activity interacts with the relationship between sitting at work and MSCs. The relationship between sitting at work and musculoskeletal pain needs further investigation, but we found indications that leisure time physical activity may counter the effects of sitting at work.

Night shift work and cardiovascular diseases among employees in Germany: five-year follow-up of the Gutenberg Health Study.

OBJECTIVE: This study aimed to determine if there is an increased risk of incident cardiovascular diseases (CVD) resulting from cumulative night shift work in the German population-based Gutenberg Health Study (GHS). METHODS: We examined working participants of the GHS at baseline and after five years. Cumulative night shift work in the 10 years before baseline was assessed and categorized as low (1-220 nights ≙ up to 1 year), middle (221-660 nights ≙ 1-3 years), and high (>660 nights ≙ more than 3 years) night shift exposure. Hazard ratios (HR) were estimated for incident "quality-assured CVD events" using Cox proportional hazard models. RESULTS: At baseline, 1092 of 8167 working participants performed night shift work. During the follow-up, 202 incident cardiovascular events occurred. The crude incidence rates for CVD per 1000 person-years were 6.88 [95% confidence interval (CI) 4.80-9.55] for night shift workers and 5.19 (95% CI 4.44-6.04) for day workers. Cumulative incidence curves showed a higher cumulative incidence in workers exposed to night shift work compared to day workers after five years. The adjusted HR for incident CVD events were 1.26 (95% CI 0.68-2.33), 1.37 (95% CI 0.74-2.53) and 1.19 (95% CI 0.67-2.12) for employees in the low, middle and high night shift categories compared to employees without night shift work, respectively. CONCLUSIONS: The observed tendencies indicate that night shift work might be negatively associated with cardiovascular health. We expect the continued follow-up will clarify the long-term impact of night shift work.

Health effects of railway-induced vibration combined with railway noise - A systematic review with exposure-effect curves.

BACKGROUND: The combined health impact of concurrent railway noise and railway vibration exposure is not yet well understood. OBJECTIVES: This systematic review gives an overview of epidemiological studies on health effects from railway vibration, aiming to quantify this association with exposure-effect curves. Moreover, the combined health effects of vibration and concurrent noise were investigated. METHODS: We converted the vibration metric to an equivalent noise level and calculated an overall noise level by energetically summing the equivalent and railway noise level. The combined health effect was determined by using published evidence-based exposure-effect formulas. RESULTS: Studies included in this systematic review predominately investigated annoyance and self-reported sleep disturbances; no studies on manifest diseases were identified. For the combined effects of vibration and noise on "total" annoyance, the results based on the pooled analysis of CargoVibes project are recommended as conservative approach. DISCUSSION: Converting railway vibration into equivalent noise levels in dB may offer a pragmatic approach to assess the combined health effects of railway noise and railway vibration exposure. Future studies should include cardiovascular and mental diseases in addition to vibration-induced annoyance and sleep disturbances. Furthermore, future studies should include in-depth investigations of the interaction between railway noise and railway vibration to allow for a more accurate assessment of the railway-induced burden of disease.

Traffic noise annoyance in the LIFE-adult study in Germany: Exposure-response relationships and a comparison to the WHO curves.

BACKGROUND: Noise annoyance is the second-highest cause of lost disability-adjusted life-years due to environmental noise in Europe. Evidence on exposure-response relationships (ERRs) for traffic noise annoyance with more accurate exposure values is still needed. OBJECTIVES: In an analysis of the population-based LIFE-Adult study in Leipzig, Germany, we aimed to investigate the effect of road, railway (train and tram), and aircraft noise on high annoyance (HA). METHODS: Traffic exposure data was taken for 2012 and data on noise annoyance was evaluated between 2018 and 2021. HA was defined according to international standardized norms. We calculated risk estimates using logistic regression, controlling for age, sex, and socioeconomic status, and compared our ERRs with those from the last WHO review on this topic. RESULTS: Aircraft noise had the highest relative risk for noise-related HA (OR = 12.7, 95% CI: 9.37-17.10 per 10 dB Lden increase). The road and railway traffic risk estimates were similar to each other (road: OR = 3.55, 95% CI: 2.78-4.54; railway: OR = 3.31, 95% CI: 2.77-3.97 per 10 dB Lden increase). Compared to the WHO curves, the proportion of highly annoyed individuals was somewhat lower for road and rail traffic noise, but higher for aircraft noise. DISCUSSION: Aircraft noise is particularly annoying. There were differences between our study's ERRs and those in the WHO review, especially for aircraft noise. These differences may be partly explained by the improved accuracy of the exposure values, as we considered secondary road networks and tram noise, and by a lack of a nighttime flight ban at the Leipzig airport. Geographical, regional and climatic variations, inconsistency in HA cut-offs, as well as temporal developments in the annoyance experience may also explain the differences. Since ERRs serve as a basis for decision making in public policies, regular updates of the curves based on new evidence is recommended.

Traffic-Related High Sleep Disturbance in the LIFE-Adult Cohort Study: A Comparison to the WHO Exposure-Response-Curves.

Sleep is negatively affected by environmental noise. In the present study, we investigated self-reported high sleep disturbances (being "highly sleep disturbed"-HSD) from road traffic (primary and secondary road networks), rail (train and tram) and air traffic noise in the LIFE-Adult cohort study in Leipzig, Germany. For this, we used exposure data from 2012 and outcome data of Wave 2 (collected during 2018-2021). HSD was determined and defined according to internationally standardized norms. The highest risk for transportation noise-related HSD was found for aircraft noise: the odds ratio (OR) was 19.66, 95% CI 11.47-33.71 per 10 dB increase in Lnight. For road and rail traffic, similar risk estimates were observed (road: OR = 2.86, 95% CI 1.92-4.28; rail: OR = 2.67, 95% CI 2.03-3.50 per 10 dB Lnight increase). Further, we compared our exposure-risk curves with the curves of the WHO environmental noise guidelines for the European region. The proportion of individuals with HSD for a given noise level was lower for rail traffic but higher for aircraft noise in the LIFE study than in the WHO curves. For road traffic, curves are not directly comparable because we also included the secondary road network. The results of our study add to the body of evidence for increased health risks by traffic noise. Moreover, the results indicate that aircraft noise is particularly harmful to health. We recommend reconsidering threshold values for nightly aircraft exposure.

Current and projected incidence trends of pediatric-onset inflammatory bowel disease in Germany based on the Saxon Pediatric IBD Registry 2000-2014 -a 15-year evaluation of trends.

AIMS: An increasing number of children and adolescents worldwide suffer from inflammatory bowel disease (IBD) such as Crohn's disease (CD) and ulcerative colitis (UC). The present work aims to investigate the incidence, prevalence and future trends of IBD in children and adolescents in Saxony, Germany. METHODS: The Saxon Pediatric IBD Registry collected data on patients up to 15 years of age from all 31 pediatric hospitals and pediatric gastroenterologists in Saxony over a 15-year period (2000-2014). In 2019, an independent survey estimated a registry completeness of 95.7%. Age-standardized incidence rates (ASR) per 100,000 person-years (PY) and prevalence per 100,000 children and adolescents were calculated. Evaluation was also been performed in sex and age subgroups. Joinpoint and Poisson regression were used for trend analyses and projections. RESULTS: 532 patients with confirmed IBD during 2000-2014 were included in the epidemiological evaluation. 63.5% (n = 338) patients had CD, 33.1% (n = 176) had UC and 3.4% (n = 18) had unclassified IBD (IBD-U). The 15-year IBD prevalence was 111.8 [95%-CI: 102.3-121.3] per 100,000. The incidence ASR of IBD per 100,000 PY over the whole observation period was 7.5 [6.9-8.1]. ASR for the subtypes were 4.8 [4.3-5.3] for CD, 2.5 [2.1-2.9] for UC and 0.3 [0.1-0.4] for IBD-U. The trend analysis of ASR using the joinpoint regression confirmed a significant increase for incidence of IBD as well as CD. For IBD, the ASR per 100,000 PY increased from 4.6 [2.8-6.3] in 2000 to 8.2 [7.5-13.6] in 2014; projected incidence rates for IBD in Germany are 12.9 [6.5-25.5] in the year 2025 and 14.9 [6.7-32.8] in 2030, respectively. Thus, the number of new IBD diagnoses in Germany would more than triple (325%) in 2030 compared to 2000. The increase is expected to be faster in CD than UC, and be more in males than in females. The expected number of newly diagnosed children with IBD in Germany is projected to rise to about 1,584 [1,512-1,655] in 2025, and to about 1,918 [1,807-2,29] in 2030. CONCLUSION: The incidence of IBD in children and adolescents in Saxony increased at a similar rate as in other developed countries during the observation period. Given this trend, the health care system must provide adequate resources for the care of these young patients in the future.

Health and Care Dependency of Older Adults in Dresden, Germany: Results from the LAB60+ Study.

As the population in Europe ages, an increased focus on the health of older adults is necessary. The purpose of the population-based LAB60+ study was to examine the current health and care situation of the population of older adults in Dresden, Germany, and to assess the effect of age, gender, and socioeconomic status (SES) on health outcomes. In the first half of 2021, 2399 out of 6004 randomly sampled residents of Dresden aged 60 years or older answered questions on their chronic conditions, care dependency, health-related quality of life (HRQoL), and well-being, among others. Of the participants, 91.6% were afflicted with at least one chronic condition, and 73.1% had multimorbidities. More than one-tenth (11.3%) of participants were care dependent. Lower levels of HRQoL and well-being were observed compared to a published German reference population, perhaps because of the ongoing COVID-19 pandemic. Gender differences were observed for some chronic health conditions, and women had a higher risk for lower HRQoL, well-being, and depressivity compared to men. A low SES was associated with a higher risk of the vast majority of health outcomes. Particularly, socioeconomic factors and gender-related inequalities should be considered for the development of prevention and health-promoting measures during late life.

The Gutenberg health study: a five-year prospective analysis of psychosocial working conditions using COPSOQ (Copenhagen psychosocial Questoinnaire) and ERI (effort-reward imbalance).

BACKGROUND: Psychosocial working conditions were previously analyzed using the first recruitment wave of the Gutenberg Health Study (GHS) cohort (n = 5000). We aimed to confirm the initial analysis using the entire GHS population at baseline (N = 15,010) and at the five-year follow-up. We also aimed to determine the effects of psychosocial working conditions at baseline on self-rated outcomes measured at follow-up. METHODS: At baseline, working GHS participants were assessed with either the Effort-Reward-Imbalance questionnaire (ERI) (n = 4358) or with the Copenhagen Psychosocial Questionnaire (COPSOQ) (n = 4322); participants still working after five years received the same questionnaire again (ERI n = 3142; COPSOQ n = 3091). We analyzed the association between working conditions and the outcomes job satisfaction, general health, burnout, and satisfaction with life at baseline, at follow-up and also prospectively from baseline to follow-up using linear regression models. We examined the outcome variance explained by the models (R2) to estimate the predictive performance of the questionnaires. RESULTS: The models' R2 was comparable to the original baseline analyses at both t0 and t1 (R2 range: ERI 0.10-0.43; COPSOQ 0.10-0.56). However, selected scales of the regression models sometimes changed between assessment times. The prospective analysis showed weaker associations between baseline working conditions and outcomes after five years (R2 range: ERI 0.07-0.19; COPSOQ 0.07-0.24). This was particularly true for job satisfaction. After adjusting for the baseline levels of the outcomes, fewer scales still explained some of the variance in the distribution of the outcome variables at follow-up. The models using only data from t0 or t1 confirmed the previous baseline analysis. We observed a loss of explained variance in the prospective analysis models. This loss was greatest for job satisfaction, suggesting that this outcome is most influenced by short-term working conditions. CONCLUSIONS: Both the COPSOQ and ERI instruments show good criterion validity and adequately predict contemporaneously measured self-reported measurements of health and (occupational) well-being. However, the COPSOQ provides a more detailed picture of working conditions and might be preferable for improvment strategies in workplaces. Additional prospective research with shorter follow-up times would be beneficial for estimating dose-response relationships.

Intimate Partner Violence Against Women in the Arab Countries: A Systematic Review of Risk Factors.

Intimate partner violence (IPV) profoundly damages physical, sexual, reproductive, and psychological health, as well as social well-being of individuals and families. We sought in this systematic review to examine the risk factors according to the integrative ecological theoretical framework for IPV for women living in the Arab countries. We searched Embase, PubMed, PsycINFO, and SCOPUS, supplemented by hand searching of reference lists. A research strategy was developed and observational studies were included if they considered female participants (age ≥13) in heterosexual relationships, estimates of potential risk factors of IPV, and IPV as a primary outcome. We conducted a narrative synthesis of the risk factors data from 30 cross-sectional studies. Factors associated with increased IPV against women were extracted and categorized into four levels according to the updated integrative ecological model. At the individual level, risk factors were either related to victims or perpetrators of IPV. Factors relating to marriage, conflict within the family, etc., were explored and included within the family level, whereas factors relating to the extended family and the nature of marriage were included in the community level. Finally, risk factors relating to the cultural context that are influenced by the political and religious backgrounds were included in the societal level. The complex structure of violence against women in the Arab world calls for socioculturally sensitive interventions, which should be accompanied by systematic and structured work aimed at improving Arab women's status at all levels.

[Pregnant Physicians in Surgical Specialties - Implementation of the Maternity Protection Act Among Female Physicians in Saxony]. / Schwangere Ärztinnen in den operativen Fachgebieten ­ eine Befragung zur Umsetzung des Mutterschutzgesetzes unter sächsischen Fachärztinnen.

AIM: The aim of the study was to investigate compliance with occupational health and safety (OHS) among pregnant surgeons. METHODS: All female surgeons in Saxony up to 45 years of age received a written questionnaire about their work environment during pregnancy. Predefined and expert-based criteria of OHS were analyzed descriptively. Poor compliance with OSH was defined as meeting a maximum of half of the criteria. Using logistic regression, professional factors (i. e. "operating due to lack of staff") and personal factors (i. e. "operating due to residency") were investigated for poor compliance with OSH. RESULTS: Of the participating female specialists, 55% (response=39%) had performed surgery during pregnancy. On average, 7.4 of the 16 occupational health and safety measures were fulfilled (median=8; range 1-13). In none of the cases were all predefined OSH criteria fulfilled. Two-thirds of the women who worked in non-operative areas took on invasive activities. When the women were working outside the operating theatre, an average of 4.1 of 13 predefined OSH criteria was fulfilled (median=4; range 0-8). "Lack of staff" was related to poor OSH compliance in the multivariate analysis (OR=5.9 (95% CI 1.7-20.0)). CONCLUSION: The results of the study show a great need for improvement in the occupational safety of pregnant surgeons.

The Burden of Disease Due to Road Traffic Noise in Hesse, Germany.

Road-traffic-noise exposition is widespread in Germany and can have harmful health effects. As guidance for informed decision-making, we estimated the environmental burden of disease attributable to road-traffic noise in Hesse, Germany as disability-adjusted life-years (DALYs). Using detailed road-traffic-noise exposure data provided by the Hessian Agency for Nature Conservation, Environment, and Geology (HLNUG), we calculated the DALYs due to road-traffic noise > 40 dB(A) L24h (unweighted average 24 h noise level) and other noise metrics for endpoints with known dose-response functions and evidence in the literature (NORAH-study on disease risks and WHO reviews): cardiovascular disease, depressive disorders, road-traffic annoyance, and sleep disturbance. We calculated the population-attributable fractions (PAF) for road-noise-related cardiovascular disease (hypertensive heart disease, ischemic heart disease, and stroke) and depressive disorders in the population using published relative risk estimates. We multiplied the PAFs with the Hessian proportion of the 2015 WHO DALY estimates for Germany in people aged ≥ 40 years. For high annoyance and high sleep disturbance, we used published dose-response functions to determine the burden for residents of all ages. For Hesse, we found a total of 26,501 DALYs attributable to road-traffic noise or 435 DALY per 100,000 persons for the reference year, 2015. Further, we estimated that a hypothetic uniform road-traffic-noise reduction of 3 dB would prevent 23% of this burden of disease.

A Rapid Review on the Influence of COVID-19 Lockdown and Quarantine Measures on Modifiable Cardiovascular Risk Factors in the General Population.

Preceding coronavirus outbreaks resulted in social isolation, which in turn is associated with cardiovascular consequences. Whether the current COVID-19 pandemic negatively impacts cardiovascular health is unclear. The aim of the rapid review was to investigate, whether COVID-19 lockdown influences modifiable cardiovascular risk factors (i.e., physical inactivity, sedentary behaviour, smoking, alcohol use, unhealthy diet, obesity, bad blood lipids, and hypertension) in the general population. Medline and EMBASE were searched until March 2021. Title, abstracts, and full texts were screened by one reviewer and 20% by a second reviewer. Only studies using probability sampling were included in order to ensure the representativeness of the target population. Data extraction and critical appraisal were done by one reviewer and double-checked by another reviewer. We identified 32 studies that fulfilled our inclusion criteria. Findings show that physical activity decreased, and sedentary behaviour increased among all age groups during the COVID-19 lockdown. Among adults, alcohol consumption increased, dietary quality worsened, and the amount of food intake increased. Some adults reported weight gain. Studies on children and adolescents were sparse. This rapid review found a high number of epidemiological studies on the impact of COVID-19 lockdown measures on modifiable cardiovascular risk factors, but only a few used probability sampling methods.

Work-life conflict and cardiovascular health: 5-year follow-up of the Gutenberg Health Study.

INTRODUCTION: Work-life conflicts (WLC) may impact health, but few studies prospectively consider the impact of WLC on objective outcomes such as cardiovascular disease. Using data from the Gutenberg Health Study (GHS), we examined if WLC at baseline was associated with an increased five-year incidence of cardiovascular events (myocardial infarct, stroke, atrial fibrillation, peripheral artery disease, coronary artery disease, chronic heart failure, sudden cardiac death). We also considered if WLC was associated with incident hypertension and arterial stiffness and if the effects of WLC on cardiovascular health differ for men and women. METHODS: A working subsample of the 15,010 GHS cohort participants completed the Copenhagen Psychosocial Questionnaire, which included five "work-privacy conflict" questions at baseline and at the five-year follow-up. Relative risks for incident hypertension due to increased WLC at baseline (WLC scores exceeding 60 out of 100) were estimated with Poisson regression in the subgroup of participants without hypertension at baseline (n = 2426). Categories of WLC at baseline and follow-up were also used to examine the risk of hypertension due to chronic/recurrent WLC. In this subgroup, we also examined the association between WLC as a continuous score ranging from 0 to 100 with change to arterial stiffness after five years using linear regression. Hazard ratios were estimated for incident cardiovascular events in a larger subsample of participants without prevalent cardiovascular disease at baseline (n = 3698) using Cox regression. We used various multivariable regression models to adjust for sex, age, socioeconomic status, occupational, household, and cardiovascular risk factors. RESULTS: We found no association between WLC and incident hypertension or increased arterial stiffness. The fully-adjusted relative risk for WLC >60 at baseline and hypertension was 0.93 (95% 0.74-1.17). The risk of hypertension due to chronic/recurrent WLC >60 was increased but not statistically significant (RR = 1.13, 95% CI 0.83-1.54). Overall, hazard ratios for incident cardiovascular events were also not increased. However, stratifying the results by sex resulted in a hazard ratio of 1.47 (95% CI 0.54-3.98) for incident cardiovascular disease among women in the fully adjusted model. CONCLUSIONS: Although our results were not statistically significant, they indicate that WLC is negatively impacting the cardiovascular health of women. While these results need to be confirmed with additional research and a longer follow-up, interventions to prevent WLC will promote health and could be especially beneficial for women.

[Effects of Noise Protection Measures on Annoyance, Sleep Disorders, and Cardiovascular Diseases: A Model Calculation]. / Auswirkungen lärmmindernder Maßnahmen auf die Häufigkeit von Lärmbelästigung, Schlafstörungen und Herz-Kreislauf-Erkrankungen ­ eine Modellrechnung.

AIM: In Germany, traffic noise-related threshold values are currently set at 70 decibels (dB) during the day and 60 dB at night. According to recent study results, these threshold values might not sufficiently protect against disease risks. The model calculation presented here aimed to estimate the effects of 3 specific noise-protection measures on annoyance, sleep disorders, and cardiovascular diseases. METHODS: For road traffic noise and railway noise, 3 noise reduction approaches were modeled: (1) weighted 24 hours noise levels (LDEN) of at most 65 dB, and nightly sound pressure levels (LNight) of 55 dB; (2) LDEN of at most 60 dB and LNight of 50 dB; and (3) a general reduction of road and railway noise pressure levels by 3 dB. As an example, the effects of approaches (1) to (3) were determined for the study population of the NORAH study on disease risks (Rhine-Main area). The health consequences were estimated based on the results of the WHO Noise Guidelines (2018) and the NORAH study on disease risks. RESULTS: The model calculations showed that noise protection approach (1) could reduce the number of people suffering from sleep disturbances as a result of nightly traffic noise and of those highly annoyed as well as the number of people suffering from traffic-related cardiovascular disease by 5 to 10%. Noise protection approach (2) could reduce traffic-related cardiovascular diseases by at least about 10%; according to the WHO Noise Guidelines, it would even be possible to reduce road traffic noise-related ischemic heart disease by more than 30%. All of these measures would be of particular benefit to the highly exposed population - an already vulnerable group due to their limited socio-economic resources. With the general reduction of traffic noise pressure levels by 3 dB, the incidence of annoyance, sleep disturbances and cardiovascular diseases could be reduced particularly among those exposed to low to medium noise pressure levels. CONCLUSIONS: Considering the different objectives and target groups of the investigated noise protection measures, the introduction and implementation of specific threshold values should be supplemented by general noise reduction measures in the range below the threshold values.
