Retrospective analysis of the Italian exit strategy from COVID-19 lockdown.

After the national lockdown imposed on March 11, 2020, the Italian government has gradually resumed the suspended economic and social activities since May 4, while maintaining the closure of schools until September 14. We use a model of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission to estimate the health impact of different exit strategies. The strategy adopted in Italy kept the reproduction number Rt at values close to one until the end of September, with marginal regional differences. Based on the estimated postlockdown transmissibility, reopening of workplaces in selected industrial activities might have had a minor impact on the transmissibility. Reopening educational levels in May up to secondary schools might have influenced SARS-CoV-2 transmissibility only marginally; however, including high schools might have resulted in a marked increase of the disease burden. Earlier reopening would have resulted in disproportionately higher hospitalization incidence. Given community contacts in September, we project a large second wave associated with school reopening in the fall.

Occupational Physicians' Management of Workers With Multiple Sclerosis in Italy: Results From a Survey.

BACKGROUND: This study, conducted on a sample of Italian occupational physicians (OPs), aimed to gather data regarding professional activity and their needs in managing workers with multiple sclerosis. METHODS: A convenience sample of OPs recruited by e-mail invitation to the list of Italian Society of Occupational Medicine members was considered. A total of 220 OPs participated between July and October 2022. An ad hoc questionnaire was developed based on previous survey experiences. It investigated, among others, the characteristics of OP respondents, the evaluation of fitness for work issues, and the OP training and updating needs on multiple sclerosis and work. RESULTS: Ninety-one percent of OPs had to assess the fitness for work of workers with multiple sclerosis during their activity. Sixty-four percent experienced particular difficulties in issuing a fitness for work judgment. Regarding the level of knowledge on multiple sclerosis, 54% judged it sufficient. The "Assessment of fitness for work for the specific task" and the "Role of the OPs in identifying reasonable accommodations" were the most interesting training topics regarding MS management in work contexts chosen by the respondents. CONCLUSIONS: The interest in the work inclusion and job retention of people with disability, particularly the aspects linked to the Identification and implementation of reasonable accommodations, will require integration with the occupational safety and health protection system and will undoubtedly impact the OP's activities.

Relation of the work ability index to fitness for work in healthcare and public employees in a region of Northeastern Italy.

PURPOSE: Work ability indicates an individual's capacity to match job demands according to his/her physical and mental conditions and work circumstances. Occupational physicians should take into consideration the global health status of a worker in order to correctly assess if he/she is fit for the job. The aim of this study was to verify the association between fitness for work evaluation and Work Ability Index scores, as well as individual factors (age, gender, and anthropometric characteristics) and work-related variables (job type, years of working duration). METHODS: A cross-sectional study was conducted within the occupational health surveillance of health and public employers in the Friuli-Venezia Giulia region (2018-2022). The participants voluntarily agreed to answer the standard Work Ability Index questionnaire. Data were investigated by univariable as well as multivariable regression analysis. RESULTS: The Work Ability Index of the workers included in the study (N = 6893) resulted negatively associated with age, female sex, and body mass index. It was averagely lower in nurses and assistive personnel, and the highest in medical doctors and public employers. The fitness for work assessments was also statistically related to WAI scores. The results obtained from the univariable and the multivariable analysis were consistent. CONCLUSIONS: The Work Ability Index is an efficient tool to measure an individual's capability to sustain job demands, and can be taken into account to produce a correct fitness for work evaluation and consequently preserve workers' health status.

Implementing Smart Working in Public Administration: a follow up study.

BACKGROUND: Starting from February 2020, in Italy most organizations have had a forced transition to flexible working practice - called "smart working in emergency" - due to the Covid-19 epidemic outbreak. This allowed to continue work activities and services and contributed to contain the risk of infection in different sectors, particularly in the public administration. OBJECTIVES: This follow up study focussed on a panel of 187 workers from the Italian Workers' Compensation Authority taking part to a pilot project "Smart Working in INAIL" from January 2019 to December 2019. The aim was to investigate the effects of work organization on work attitudes, work-life balance and health outcomes before and after the introduction of the smart working. METHODS: The data were collected at two time points through a web-based questionnaire. The first wave aimed to collect information up to one month before the implementation of the smart working. The second wave aimed to collect information about potential changes occurred after one year of smart working. RESULTS: This study showed that high demands, low control and low social support might lead to reduced well-being and less satisfaction with work, and have an effect on work engagement and work-life balance. Particularly, improving social support can moderate the negative impact of high strain on well-being, preventing work-life imbalance and risk of isolation. DISCUSSION: Findings and future perspectives are discussed to support stakeholders in defining policies and practices concerning health and wellbeing at work while preserving productivity, for a successful implementation of smart working in the public administration.

Occupational factors in the COVID-19 pandemic in Italy: compensation claims applications support establishing an occupational surveillance system.

INTRODUCTION: The SARS-CoV-2 pandemic is an impacting challenge for occupational health. Epidemiological surveillance of COVID-19 includes systematic tracking and reporting of the total cases and deaths, but suitable experiences of surveillance systems for identifying the occupational risk factors involved in the COVID-19 pandemic are still missing, despite the interest for occupational safety and health. METHODS: A methodological approach has been implemented in Italy to estimate the occupational risk of infection, classifying each economic sector as at low, medium-low, medium-high and high risk, based on three parameters: exposure probability, proximity index and aggregation factor. Furthermore, during the epidemic emergency, the Italian Workers' Compensation Authority introduced the notation of COVID-19 work-related infection as an occupational injury and collected compensation claims of workers from the entire national territory. RESULTS: According to compensation claims applications, COVID-19 infection in Italy has been acquired at the workplace in a substantial portion of the total cases (19.4%). The distribution of the economic sectors involved is coherent with the activities classified at risk in the lockdown period. The economic sectors mostly involved were human health and social work activities, but occupational compensation claims also include cases in meat and poultry processing plants workers, store clerks, postal workers, pharmacists and cleaning workers. CONCLUSIONS: There is a need to go towards an occupational surveillance system for COVID-19 cases, including an individual anamnestic analysis of the circumstances in which the infection is acquired, for the prevention of occupational infectious risk, supporting insurance system effectiveness and managing vaccination policies.

[Preliminary results of a cognitive survey among the members of the Italian Medical Radiation Protection Society(AIRM): from characterization of the professional activity to identification of training needs]. / Risultati preliminari di un'indagine conoscitiva tra i soci dell'Associazione italiana radioprotezione medica (AIRM): dalla caratterizzazione dell'attività professionale all'individuazione del fabbisogno formativo.

OBJECTIVES: For several decades, the Italian Association of Medical Radioprotection (AIRM) is engaged in the promotion of scientific, technical, and methodological knowledge in the field of medical radioprotection. METHODS: Starting from the results of the previous study conducted in 2013, AIRM has carried out a new survey among its members. This survey was carried out through a self-administered questionnaire to be completed online on a platform set up on the association's website. RESULTS: The preliminary data collected by the survey provide both the personal/professional description of the AIRM members and an in-depth analysis regarding the need for training updates in the field of radioprotection. CONCLUSIONS: The results obtained will be used by the AIRM to support its commitment, now over a decade, in the offer of current and effective radioprotection update programs.

Economic impact of malignant mesothelioma in Italy: an estimate of the public and social costs.

BACKGROUND: Despite their considerable interest for public health policies and for occupational disease management and assessment, the economic costs of asbestos-related diseases (ARDs) for society have not been fully estimated or even frequently discussed. OBJECTIVES: The aim of this study was to estimate the economic burden of mesothelioma in Italy by assessing the overall societal cost of the disease, applying an econometric model. METHODS: We analyzed two main cost groups, public and social. The first includes expenditure borne by the State and other public bodies (medical care costs, insurance, tax and benefits), while the latter uses the human capital approach to measure the loss of productivity suffered by the economy as a whole. RESULTS: We provide an estimate of euro 33,000 per patient for medical care costs and euro 25,000 for insurance and compensation; tax and benefits seem to roughly compensate. We estimated a loss of more than euro 200,000 per patient, in terms of loss of production. CONCLUSIONS: This study offers a practical approach for estimating the economic impact of mesothelioma, and provides empirical evidence of the huge economic burden linked to this disease, with its high etiologic fraction.

[The INSuLa Project: a knowledge survey among workers]. / Progetto INSuLa: I'indagine conoscitiva sui lavoratori.

The INSuLa project consisted of a national survey on health and safety at work involving all the relevant actors such as workers, employers, occupational physicians (MC), worker safety representatives (RLS), prevention and safety service in the workplace (SPSAL). The survey aimed, on one hand, at investigating workers' risk perceptions at the workplace and, on another hand, at exploring the general level of awareness about the enforcement of the Legislative Decree 81/2008 and subsequent amendments. The survey was conducted on a stratified sample of8000 workers representative of the national situation taking into consideration some of the most important socio-demographic and occupational variables, such as gender, geographic area, age, type of contract and sector of activity. The analysis of the results presented here and the subsequent secondary analyses will contribute to identify the needs and critical issues for implementing preventive interventions at the workplaces, also in consideration of the emerging risks and changes in the world of work.

Measures of Work-life Balance and Interventions of Reasonable Accommodations for the Return to Work of Cancer Survivors: A Scoping Review.

Background: Nearly half of patients diagnosed with cancer are in the middle of their traditional working age. The return to work after cancer entails challenges because of the cancer or treatments and associated with the workplace. The study aimed at providing more insight into the occupational outcomes encountered by workers with cancer and to provide interventions, programs, and practices to support their return to work. Methods: A scoping review was conducted using the Arksey and O'Malley framework and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for scoping review guidelines. Relevant studies were systematically searched in PubMed/MEDLINE, SCOPUS and Grey literature from 01 January 2000 to 22 February 2024. Results: The literature search generated 3,017 articles; 53 studies were considered eligible for this review. Most of the studies were longitudinal and conducted in Europe. Three macroarea were identified: studies on the impact of cancer on workers in terms of sick leave, employment, return to work, etc.; studies reporting wider issues that may affect workers, such as the compatibility of treatment and work and employment; studies reporting interventions or policies aiming to promote the return to work. Conclusion: There is a lack in the literature in defining multidisciplinary interventions combining physical, psycho-behavioural, educational, and vocational components that could increase the return-to-work rates. Future studies should focus on interdisciplinary return to work efforts with multiple stakeholders with the involvement of an interdisciplinary teamwork (healthcare workers and employers) to combine these multidisciplinary interventions at the beginning of sick leave period.

The relevance of socio-demographic and occupational variables for the assessment of work-related stress risk.

BACKGROUND: Work-related stress is widely recognized as one of the major challenges to occupational health and safety. The correlation between work-related stress risk factors and physical health outcomes is widely acknowledged. This study investigated socio-demographic and occupational variables involved in perceived risk of work-related stress. METHODS: The Italian version of the Health and Safety Executive Management Standards Indicator Tool was used in a large survey to examine the relationship between work-related stress risks and workers' demographic and occupational characteristics. Out of 8,527 questionnaires distributed among workers (from 75 organizations) 6,378 were returned compiled (74.8%); a set of mixed effects models were adopted to test single and combined effects of the variables on work-related stress risk. RESULTS: Female workers reported lower scores on control and peer support and more negative perceptions of relationships and change at work than male workers, most of them with full-time contracts. Age, job seniority, and educational level appeared positively correlated with control at work, but negatively with job demands. Fixed-term workers had positive perceptions regarding job demands and relationships, but more difficulties about their role at work than permanent workers. A commuting time longer than one hour and shift work appeared to be associated with higher levels of risk factors for work-related stress (except for role), the latter having more negative effects, increasing with age. CONCLUSIONS: The findings suggest that the assessment and management of work-related stress risk should consider specific socio-demographic and occupational risk factors such as gender, age, educational level, job status, shift work, commuting time, job contracts.

The challenges of managing patients with cancer in the workplace: Needs, opportunities and perspectives of occupational physicians.

Cancer is a global major public health problem since it is a leading cause of death, accounting for nearly 10 million deaths in 2020 worldwide and the most recent epidemiological data suggested that its global impact is growing significantly. In this context, cancer survivors have to live for a long time often in a condition of disability due to the long-term consequences, both physical and psychological. These difficulties can seriously impair their working ability, limiting the employability. In this context, the occupational physician plays a key role in the implementation and enforcement of measures to support the workers affected by cancer, to address issues such as the information on health promotion, the analysis of work capacity and the management of disability at work and also promoting a timely and effective return to work and preserving their employability. Therefore, the aim of this study was to gather useful information to support the occupational physicians in the management of workers affected by cancer, through a survey on 157 Italian occupational physicians. Based on the interviewees' opinions, the most useful occupational safety and health professionals in terms of job retention and preservation of workers affected by cancer are the employers and the occupational physicians themselves, whose role is crucial in identifying and applying the most effective reasonable accommodations that should be provided to the workers affected by cancer. The provision of these accommodations take place on the occasion of mandatory health surveillance medical examination to which the worker affected by cancer is subjected when he returns to work. Results on training and information needs showed that the management of the workers affected by cancer is essentially centered on an appropriate fitness for work judgment and on the correct performance of health surveillance. However, an effective and successful management model should be based on a multidisciplinary and integrated approach that, from the earliest stages of the disease, involves the occupational physicians and employers.

Covid-19 Occupational Risk Incidence and Working Sectors Involved During the Pandemic in Italy.

Background: Starting from March 2020 until December 2021, different phases of Covid-19 pandemic have been identified in Italy, with several containing/lifting measures progressively enforced by the National government. In the present study, we investigate the change in occupational risk during the subsequent pandemic phases and we propose an estimate of the incidence of the cases by economic sector, based on the analysis of insurance claims for compensation for Covid-19. Methods: Covid-19 epidemiological data available for the general population and injury claims of workers covered by the Italian public insurance system in 2020-2021 were analyzed. Monthly Incidence Rate of Covid-19 compensation claims per 100,000 workers (MIRw) was calculated by the economic sector and compared with the same indicator for general population in different pandemic periods. Results: The distribution of Covid-19 MIRw by sector significantly changed during the pandemic related to both the strength of different waves and the mitigation/lifting strategies enforced. The level of occupational fraction was very high at the beginning phase of the pandemic, decreasing to 5% at the end of 2021. Healthcare and related services were continuously hit but the incidence was significantly decreasing in 2021 in all sectors, except for postal and courier activities in transportation and storage enterprises. Conclusion: The analysis of compensation claim data allowed to identify time trends for infection risk in different working sectors. The claim rates were highest for human health and social work activities but the distribution of risk among sectors was clearly influenced by the different stages of the pandemic.

Work-related stress risk assessment in Italy: the validation study of health safety and executive indicator tool.

INTRODUCTION: In compliance with the Italian occupational health and safety regulatory framework, as provided by the Lgs. Decree 81/2008, the "work-related stress" risk assessment should follow the same principles as other risk assessments, in accordance with the European Agreement of 8 October 2004; therefore, validated and scientifically proven methodological tools are needed to conduct an adequate work-related stress risk assessment. The UK's Health Safety and Executive (HSE) Indicator Tool (IT) is used for assessing the risk of work-related stress. The aim of this study is to test the factor structure of IT as a measure of work-related stress in a sample of Italian workers. METHODS: Data collected from 65 Italian organizations (6378 workers) was used for a Confirmatory Factor Analysis (CFA) on the 35-item seven-factor model. RESULTS: The results showed acceptable fit to the data (CFI .90; TLI .89, RMSEA .045). A second CFA was done to test a 35-item six-factor model (CFI .89, TLI .87, RMSEA .047). Both models were tested after removing six items (factor loadings less than .50.), resulting in a 29-item model. Here again, there was an acceptable fit to the data (29-item seven-factor model: CFI .93, TLI .91, RMSEA .044; 29-item six-factor model: CFI .92, TLI .90, RMSEA .046). DISCUSSIONS: These findings show that the HSE model satisfactorily adapts to use in a sample of Italian workers. One of the most important innovations introduced in the assessment of work-related stress with the HSE IT is the global approach for identifying work-related stress risk factors, aimed at establishing the best strategy from the viewpoints of prevention officers and also of workers.

Association between environmental exposure to benzene and oxidative damage to nucleic acids in children.

OBJECTIVES: To evaluate the association between environmental exposure to benzene and oxidative damage to nucleic acids in children, also considering the role of Environmental Tobacco Smoke (ETS). METHODS: 396 children living in central Italy were recruited in districts with different urbanization and air pollution. All biomarkers were determined in spot urine samples by mass spectrometric techniques to assess exposure [benzene (U-Benz), and its metabolites (t,t-muconic and S-phenylmercapturic acids, t,t-MA and S-PMA, respectively), cotinine] and nucleic acid oxidation [8-oxo-7, 8-dibydro-2'-deoxyguanosine (8-oxodGuo), 8-oxo-7, 8-dihydroguanosine (8-oxoGuo), and 8-oxo-7, 8-dihydroguanine (8-oxoGua)]. RESULTS: Biomarkers of exposure and nucleic acid oxidation increased with urbanization and were correlated with each other (r > 0.18, p < 0.005). In a multiple linear regression model, benzene exposure, assessed by S-PMA and t,t-MA, was associated (p < 0.0001) with both 8-oxodGuo (R2 = 0.392) and 8-oxoGuo (R2 = 0.193) in all areas of residence, with similar slopes. CONCLUSIONS: (i) Biomarkers of exposure to benzene increased as a function of environmental air pollution and urbanization level; (ii) U-Benz clearly distinguished both exposure to ETS and areas of residence, whereas benzene metabolites were associated only with the latter; (iii) the variance of 8-oxodGuo and 8-oxoGuo was accounted for by environmental benzene exposure, thus suggesting that benzene is a good tracer of other components of complex mixtures of pollutants causing oxidative damage to nucleic acids.

The Impact of the First Wave of the COVID-19 Pandemic on Healthcare Workers: An Italian Retrospective Study.

Healthcare workers (HCWs) played an essential role in managing the COVID-19 pandemic. The Italian Workers' Compensation Authority (INAIL) and the Italian National Institute of Health (ISS) developed a retrospective study to analyze and understand trends and characteristics of infections among HCWs during the first wave of the pandemic. Between May and September 2020, Italian Regions retrospectively collected anonymous data regarding HCWs infected from the beginning of the pandemic until 30 April 2020 from their administrative sources through a questionnaire asking for socio-demographic and occupational information about the characteristics of contagion and disease outcome. Almost 16,000 valid questionnaires were received. Logistic regression was performed to ascertain the effect of age, gender, geographical macro area, profession, and pre-existing health conditions on the likelihood of HCWs developing more severe forms of COVID-19 (at least hospitalization with mild symptoms). All predictor variables were statistically significant. HCWs at higher risk of developing a more severe disease were males (OR: 1.90; 95% CI: 1.44-2.51), older than 60 years of age (OR: 6.00; 95% CI: 3.30-10.91), doctors (OR: 4.22; 95% CI: 2.22-9.02), working in Lombardy (OR: 55.24; 95% CI: 34.96-87.29) and with pre-existing health conditions (OR: 1.90; 95% CI: 1.43-2.51). This study analyses the main reasons for the overload put on the National Health Service by the first wave of the pandemic and the risk of infection for HCWs by age, gender, occupational profile and pre-existing health conditions. Improved knowledge, availability of personal protective equipment (PPE) and a tight vaccination campaign for HCWs strongly changed the trend of infections among HCWs, with substantial elimination of serious and fatal cases.

Global Policy Responses to the COVID-19 Pandemic: Results of the ICOH Survey.

Background: On the basis of its role for the development of occupational health research, information, good practices, the International Commission on Occupational Health (ICOH) launched the present survey to collect information on public health and prevention policies put in place by the governments of the countries in the world to contain the pandemic. Methods: A cross-sectional study was conducted through an online questionnaire focused on COVID-19 data, public health policies, prevention measures, support measures for economy, work, and education, personal protective equipment, intensive care units, contact tracing, return to work, and the role of ICOH against COVID-19. The questionnaire was administered to 113 ICOH National Secretaries and senior OSH experts. Collected data refer to the period ranging from the beginning of the pandemic in each country to June 30, 2020. Results: A total of 73 questionnaires from 73 countries around the world were considered valid, with a 64.6% response rate. Most of the respondents (71.2%) reported that the state of emergency was declared in their country, and 86.1% reported lockdown measures. Most of the respondents (66.7%) affirmed that the use of face masks was compulsory in their country. As for containment measures, 97.2% indicated that mass gatherings (meetings) were limited. Regarding workplace closing, the most affected sector was entertainment (90.1%). Conclusion: The results of this survey are useful to gain a global view on COVID-19 policy responses at country level.

Risk assessment at work and prevention strategies on COVID-19 in Italy.

The COVID-19 pandemic has spread worldwide, with considerable public health and socio-economic impacts that are seriously affecting health and safety of workers, as well as their employment stability. Italy was the first of many other western countries to implement extended containment measures. Health workers and others employed in essential sectors have continued their activity, reporting high infection rate with many fatalities. The epidemiological trend highlighted the importance of work as a substantial factor to consider both when implementing strategies aimed at containing the pandemic and shaping the lockdown mitigation strategy required for sustained economic recovery. To support the decision-making process, we have developed a strategy to predict the risk of infection by SARS-CoV-2 in the workplace based on the analysis of the working process and proximity between employees; risk of infection connected to the type of activity; involvement of third parties in the working processes and risk of social aggregation. We applied this approach to outline a risk index for each economic activity sector, with different levels of detail, also considering the impact on mobility of the working population. This method was implemented into the national epidemiological surveillance model in order to estimate the impact of re-activation of specific activities on the reproduction number. It has also been adopted by the national scientific committee set up by the Italian Government for action-oriented policy advice on the COVID-19 emergency in the post lockdown phase. This approach may play a key role for public health if associated with measures for risk mitigation in enterprises through strategies of business process re-engineering. Furthermore, it will make a contribution to reconsidering the organization of work, including also innovation and fostering the integration with the national occupational safety and health (OSH) system.

Contribution of ICOH to Address the Different OSH Needs among Countries: Results of a Survey.

The aim of this study is to map the coverage of occupational safety and health (OSH) rules and provisions and their enforcement at a country level worldwide. Members' participation in the International Commission on Occupational Health (ICOH) activities was also investigated. We used a questionnaire-based survey to collect data. An online questionnaire was administered from February 14 to March 18, 2018 to all ICOH members for the triennium 2015 to 2017 (n = 1929). We received 384 completed questionnaires from 79 countries, with a 20% response rate. To synthesize information about the coverage of OSH rules and provisions and their level of enforcement, a synthetic coverage index was calculated and combined with country, gross domestic product (GDP) per capita and the human development index (HDI). We used multiple correspondence analysis (MCA) to analyze the members' participation in ICOH activities. More than 90.0% of the sample declared that in their own country there is a set of rules and provisions regulating OSH in the workplace, and training procedures and tools to improve workers' awareness. However, these rules and training procedures are mainly "partially" enforced and utilized (39.0% and 45.4%). There was no statistically significant association between country and GDP per capita and the synthetic coverage index, whilst controlling for HDI. The level of engagement in ICOH activities is higher in senior members (aged 65 years or older), coming from high-income countries, having held a position within ICOH, with a higher level of education and a researcher position. An integrated and multidisciplinary approach, which includes research, education and training, is needed to address OSH issues and their impact both at global and country level.

The effect of occupational exposure to noise on ischaemic heart disease, stroke and hypertension: A systematic review and meta-analysis from the WHO/ILO Joint Estimates of the Work-Related Burden of Disease and Injury.

BACKGROUND: The World Health Organization (WHO) and the International Labour Organization (ILO) are developing joint estimates of the work-related burden of disease and injury (WHO/ILO Joint Estimates), with contributions from a large number of individual experts. Evidence from mechanistic data suggests that occupational exposure to noise may cause cardiovascular disease (CVD). In this paper, we present a systematic review and meta-analysis of parameters for estimating the number of deaths and disability-adjusted life years from CVD that are attributable to occupational exposure to noise, for the development of the WHO/ILO Joint Estimates. OBJECTIVES: We aimed to systematically review and meta-analyse estimates of the effect of any (high) occupational exposure to noise (≥85 dBA), compared with no (low) occupational exposure to noise (<85 dBA), on the prevalence, incidence and mortality of ischaemic heart disease (IHD), stroke, and hypertension. DATA SOURCES: A protocol was developed and published, applying the Navigation Guide as an organizing systematic review framework where feasible. We searched electronic academic databases for potentially relevant records from published and unpublished studies up to 1 April 2019, including International Trials Register, Ovid MEDLINE, PubMed, Embase, Lilacs, Scopus, Web of Science, and CISDOC. The MEDLINE and Pubmed searches were updated on 31 January 2020. We also searched grey literature databases, Internet search engines and organizational websites; hand-searched reference lists of previous systematic reviews and included study records; and consulted additional experts. STUDY ELIGIBILITY AND CRITERIA: We included working-age (≥15 years) workers in the formal and informal economy in any WHO and/or ILO Member State but excluded children (<15 years) and unpaid domestic workers. We included randomized controlled trials, cohort studies, case-control studies and other non-randomized intervention studies with an estimate of the effect of any occupational exposure to noise on CVD prevalence, incidence or mortality, compared with the theoretical minimum risk exposure level (<85 dBA). STUDY APPRAISAL AND SYNTHESIS METHODS: At least two review authors independently screened titles and abstracts against the eligibility criteria at a first stage and full texts of potentially eligible records at a second stage, followed by extraction of data from qualifying studies. We prioritized evidence from cohort studies and combined relative risk estimates using random-effect meta-analysis. To assess the robustness of findings, we conducted sensitivity analyses (leave-one-out meta-analysis and used as alternative fixed effects and inverse-variance heterogeneity estimators). At least two review authors assessed the risk of bias, quality of evidence and strength of evidence, using Navigation Guide tools and approaches adapted to this project. RESULTS: Seventeen studies (11 cohort studies, six case-control studies) met the inclusion criteria, comprising a total of 534,688 participants (39,947 or 7.47% females) in 11 countries in three WHO regions (the Americas, Europe, and the Western Pacific). The exposure was generally assessed with dosimetry, sound level meter and/or official or company records. The outcome was most commonly assessed using health records. We are very uncertain (low quality of evidence) about the effect of occupational exposure to noise (≥85 dBA), compared with no occupational exposure to noise (<85 dBA), on: having IHD (0 studies); acquiring IHD (relative risk (RR) 1.29, 95% confidence interval (95% CI) 1.15 to 1.43, two studies, 11,758 participants, I2 0%); dying from IHD (RR 1.03, 95% CI 0.93-1.14, four studies, 198,926 participants, I2 26%); having stroke (0 studies); acquiring stroke (RR 1.11, 95% CI 0.82-1.65, two studies, 170,000 participants, I2 0%); dying from stroke (RR 1.02, 95% CI 0.93-1.12, three studies, 195,539 participants, I2 0%); having hypertension (0 studies); acquiring hypertension (RR 1.07, 95% CI 0.90-1.28, three studies, four estimates, 147,820 participants, I2 52%); and dying from hypertension (0 studies). Data for subgroup analyses were missing. Sensitivity analyses supported the main analyses. CONCLUSIONS: For acquiring IHD, we judged the existing body of evidence from human data to provide "limited evidence of harmfulness"; a positive relationship is observed between exposure and outcome where chance, bias, and confounding cannot be ruled out with reasonable confidence. For all other included outcomes, the bodies of evidence were judged as "inadequate evidence of harmfulness". Producing estimates for the burden of CVD attributable to occupational exposure to noise appears to not be evidence-based at this time. PROTOCOL IDENTIFIER: 10.1016/j.envint.2018.09.040.
