OBJECTIVE: This study investigated whether using thermometers clipped on workers' shoes would result in different heat exposure estimation and work-rest schedules compared to using area-level meteorological data alone. METHODS: Alabama workers (n = 51) were individually monitored using thermometers on shoes. Wet Bulb Globe Temperature (WBGT) was estimated using thermometer temperatures (WBGT (personal)) or nearby weather station temperatures (WBGT (WS)). Work-rest schedules were determined from WBGT, clothing, and hourly metabolic rates estimated from self-reported tasks and bodyweight...

OBJECTIVE: Our objective is to propose a simple procedure for evaluating potential recent heavy exposure to tremolite. METHODS: One day after an accidental exposure to tremolite in rock dust, sputum was sampled; 3 months later a laryngeal lavage was taken. The sputum was examined with scanning electron microscopy (SEM); the lavage was examined with transmission electron microscopy (TEM). RESULTS: The sputum was found to contain abundant tremolite while the lavage contained very thin, high aspect-ratio fibers, many in the "Stanton Fiber" range...

: This cross-sectional study investigated the association between long working hours and prevalence of poor self-rated health (SRH) in Korean young workers using data from the 6 Korea Youth Panel Survey 2007. A total of 3,317 young wage workers were included. Weekly working hours were divided into four groups (36-40 h, 41-52 h, 53-60 h, and >60 h per week). Multiple logistic regression was performed to investigate the association between long working hours and SRH, adjusting for demographic and work-related factors...

OBJECTIVES: To assess the role of agricultural work, pesticide exposure and age at first farm labor exposure in breast cancer risk among Hispanic women in Central California. METHODS: A breast cancer (BC) case control study was conducted. Latina BC cases were identified through the California Cancer Registry and controls were recruited. Both cases and controls completed a detailed questionnaire. Pesticide exposure data was obtained by linking the crops, work locations and dates worked in specific farm jobs with the California Department of Pesticide Regulation (DPR) Pesticide Use Reports (PUR)...

OBJECTIVE: To assess the validity and reliability of a firefighting simulation test (FFST). METHODS: Sixty-nine operational firefighters completed a best-effort FFST on one occasion and twenty-two participants completed a further FFST. All participants completed a maximal treadmill test to determine cardiorespiratory fitness (VO2max). RESULTS: Time to complete the FFST demonstrated a strong inverse relationship with VO2max (r = -0.73), although the prediction error was high...

OBJECTIVE: To describe characteristics of claimants a year after report of an occupational injury associated with long-term disability benefits for income. METHOD: Univariate and multivariate logistic regression analyses on self-reported data and register data. PRIMARY OUTCOME: long-term disability benefits. RESULTS: Respondent claimants on benefits had a work ability of 2.72 (scale 1-10 - low to high) with slight increase from baseline...

OBJECTIVE: To investigate whether work ability plays a role in termination of employment (resignation or dismissal) in the short-to-medium run. METHODS: Four-year cohort study with 1,060 Brazilian hospital workers. The outcome was final employment status (active, resignation or dismissal). Multinomial models were fit. RESULTS: At the end of follow-up 14.3% of the workers had resigned and 34.0% were dismissed. Impaired work ability was a risk factor for dismissal (RRR = 1...

OBJECTIVE: Analyze tweets concerning asthma and COPD. METHODS: Approximately 40,000 tweets containing asthma or COPD were analyzed. Lexical analysis ranked terms and domains of interest, compared COPD to asthma tweets, evaluated co-occurrence of terms within tweets, and assessed differences by source (personal, institutional, or retweet). The frequency of indicator terms relevant to occupational health was determined. RESULTS: Many tweets address community pollution and effects on children, but there is much less interest in work-related factors and occupational regulatory agencies...

OBJECTIVES: This study aimed to describe a workplace intervention to sensitize employees to sleep problems, and to evaluate the medium-term impact of this intervention on participants' sleep status. METHODS: Employees of different sites (China, France, Spain, United Kingdom) of a multinational company were offered a face-to-face session on sleep hygiene with a health professional using a tablet application providing feedback by email. Data on sleep status were collected through an interactive questionnaire at baseline (N = 834 participants) and at six-month follow-up (n = 291, 34...

OBJECTIVES: To estimate the risk of cardiovascular disease (CVD) caused by working hours in the South Korean working population stratified by sex and type of work. METHODS: We analyzed longitudinal data from the Korean Longitudinal Study of Aging in 2006. The risk of CVD associated with working hours was estimated using Cox regression analysis. In addition, the analysis was conducted by stratifying the sample by sex and type of work (wage work and self-employment)...

OBJECTIVE: To explore the risk of having musculoskeletal conditions (MSKs) associated with sitting and sleeping time during workdays, presenteeism, work engagement anxiety and depression in a sample of UK HGV drivers. METHODS: 88 male drivers participated in this cross-sectional study. Binary logistic regression analyses were performed to explore the associations between two-or-more MSKs and common health risk factors. RESULTS: Possessing two or more MSKs is associated with prolonged sitting time (OR 4...

BACKGROUND: Antidepressants, benzodiazapines and opioid medications are used to manage the pain, anxiety or depression associated with workplace injuries. OBJECTIVE: To evaluate the impact of these medications on workers' compensation costs and time lost from work. METHODS: A cohort of 22,383 indemnity claims from 2008-2013 were evaluated for the association of prescribed medications on claim cost and delayed claim closure controlling for confounders...

OBJECTIVE: This cross-sectional study examined the interrelationships between workplace movement (sitting, standing, and stepping), availability of discussion space, and face-to-face (FTF) interactions between workers. METHODS: Desk-based workers (n=221) wore an activity monitor for seven days and self-reported their weekly frequency of FTF interactions and discussion space availability. Negative binomial regression models examined behavioral and spatial factors associated with the frequency of FTF interactions...

OBJECTIVE: To compare physiological responses between two firefighting simulations with different recovery periods, one having work bouts intercalated by a shortened recovery period. METHODS: Thirteen male firefighters participated in two different simulations, which comprised two identical 25-minute effort bouts (E1 and E2) intercalated by a recovery period of either 20 (T20) or 5 (T5) minutes. RESULTS: From E1 to E2, the increase of mean heart rate (HR) (26 ± 5 vs 14 ± 5 bpm, P < 0...

OBJECTIVE: In this cohort mortality study we used an exposure index to evaluate individual cumulative exposure as proxy of asbestos dose and we evaluated change in cancer mortality pattern after long time since the end of exposure. METHODS: We calculated SMRs for several causes of death stratified by latency, cumulative exposure and time since last exposure (TSLE). RESULTS: Latency: we observed a peak and then a decrease in SMR for lung, pleural and peritoneal cancer...
