Implications of Race Adjustment in Lung-Function Equations.

BACKGROUND: Adjustment for race is discouraged in lung-function testing, but the implications of adopting race-neutral equations have not been comprehensively quantified. METHODS: We obtained longitudinal data from 369,077 participants in the National Health and Nutrition Examination Survey, U.K. Biobank, the Multi-Ethnic Study of Atherosclerosis, and the Organ Procurement and Transplantation Network. Using these data, we compared the race-based 2012 Global Lung Function Initiative (GLI-2012) equations with race-neutral equations introduced in 2022 (GLI-Global). Evaluated outcomes included national projections of clinical, occupational, and financial reclassifications; individual lung-allocation scores for transplantation priority; and concordance statistics (C statistics) for clinical prediction tasks. RESULTS: Among the 249 million persons in the United States between 6 and 79 years of age who are able to produce high-quality spirometric results, the use of GLI-Global equations may reclassify ventilatory impairment for 12.5 million persons, medical impairment ratings for 8.16 million, occupational eligibility for 2.28 million, grading of chronic obstructive pulmonary disease for 2.05 million, and military disability compensation for 413,000. These potential changes differed according to race; for example, classifications of nonobstructive ventilatory impairment may change dramatically, increasing 141% (95% confidence interval [CI], 113 to 169) among Black persons and decreasing 69% (95% CI, 63 to 74) among White persons. Annual disability payments may increase by more than $1 billion among Black veterans and decrease by $0.5 billion among White veterans. GLI-2012 and GLI-Global equations had similar discriminative accuracy with regard to respiratory symptoms, health care utilization, new-onset disease, death from any cause, death related to respiratory disease, and death among persons on a transplant waiting list, with differences in C statistics ranging from -0.008 to 0.011. CONCLUSIONS: The use of race-based and race-neutral equations generated similarly accurate predictions of respiratory outcomes but assigned different disease classifications, occupational eligibility, and disability compensation for millions of persons, with effects diverging according to race.

A longitudinal linkage study of occupation and ischaemic heart disease in the general and Maori populations of New Zealand.

OBJECTIVES: Occupation is a poorly characterised risk factor for cardiovascular disease (CVD) with females and indigenous populations under-represented in most research. This study assessed associations between occupation and ischaemic heart disease (IHD) in males and females of the general and Maori (indigenous people of NZ) populations of New Zealand (NZ). METHODS: Two surveys of the NZ adult population (NZ Workforce Survey (NZWS); 2004-2006; n = 3003) and of the Maori population (NZWS Maori; 2009-2010; n = 2107) with detailed occupational histories were linked with routinely collected health data and followed-up until December 2018. Cox regression was used to calculate hazard ratios (HR) for IHD and "ever-worked" in any of the nine major occupational groups or 17 industries. Analyses were controlled for age, deprivation and smoking, and stratified by sex and survey. RESULTS: 'Plant/machine operators and assemblers' and 'elementary occupations' were positively associated with IHD in female Maori (HR 2.2, 95%CI 1.2-4.1 and HR 2.0, 1.1-3.8, respectively) and among NZWS males who had been employed as 'plant/machine operators and assemblers' for 10+ years (HR 1.7, 1.2-2.8). Working in the 'manufacturing' industry was also associated with IHD in NZWS females (HR 1.9, 1.1-3.7), whilst inverse associations were observed for 'technicians and associate professionals' (HR 0.5, 0.3-0.8) in NZWS males. For 'clerks', a positive association was found for NZWS males (HR 1.8, 1.2-2.7), whilst an inverse association was observed for Maori females (HR 0.4, 0.2-0.8). CONCLUSION: Associations with IHD differed significantly across occupational groups and were not consistent across males and females or for Maori and the general population, even within the same occupational groups, suggesting that current knowledge regarding the association between occupation and IHD may not be generalisable across different population groups.

Quantification of Occupational and Community Risk Factors for SARS-CoV-2 Seropositivity Among Health Care Workers in a Large U.S. Health Care System.

BACKGROUND: Identifying occupational risk factors for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among health care workers (HCWs) can improve HCW and patient safety. OBJECTIVE: To quantify demographic, occupational, and community risk factors for SARS-CoV-2 seropositivity among HCWs in a large health care system. DESIGN: A logistic regression model was fitted to data from a cross-sectional survey conducted in April to June 2020, linking risk factors for occupational and community exposure to coronavirus disease 2019 (COVID-19) with SARS-CoV-2 seropositivity. SETTING: A large academic health care system in the Atlanta, Georgia, metropolitan area. PARTICIPANTS: Employees and medical staff members elected to participate in SARS-CoV-2 serology testing offered to all HCWs as part of a quality initiative and completed a survey on exposure to COVID-19 and use of personal protective equipment. MEASUREMENTS: Demographic risk factors for COVID-19, residential ZIP code incidence of COVID-19, occupational exposure to HCWs or patients who tested positive on polymerase chain reaction test, and use of personal protective equipment as potential risk factors for infection. The outcome was SARS-CoV-2 seropositivity. RESULTS: Adjusted SARS-CoV-2 seropositivity was estimated to be 3.8% (95% CI, 3.4% to 4.3%) (positive, n = 582) among the 10 275 HCWs (35% of the Emory Healthcare workforce) who participated in the survey. Community contact with a person known or suspected to have COVID-19 (adjusted odds ratio [aOR], 1.9 [CI, 1.4 to 2.6]; 77 positive persons [10.3%]) and community COVID-19 incidence (aOR, 1.5 [CI, 1.0 to 2.2]) increased the odds of infection. Black individuals were at high risk (aOR, 2.1 [CI, 1.7 to 2.6]; 238 positive persons [8.3%]). LIMITATIONS: Participation rates were modest and key workplace exposures, including job and infection prevention practices, changed rapidly in the early phases of the pandemic. CONCLUSION: Demographic and community risk factors, including contact with a COVID-19-positive person and Black race, are more strongly associated with SARS-CoV-2 seropositivity among HCWs than is exposure in the workplace.

Hepatotoxicity of aflatoxin B1 and its oxidative effects in wood dust Egyptian exposed workers.

The goal of the present study is to estimate the oxidative effects of AFB1 induced hepatotoxicity in furniture wood dust exposed workers. A cross-sectional comparative study was designed for comparing AFB1/albumin (AFB1/alb) levels and liver functions [alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP)], malondialdehyde (MDA), glutathione peroxidase (GPx), catalase (CAT) and superoxide dismutase (SOD) in 88 furniture workers and 78 controls not occupationally exposed to wood dust. The AFB1/Alb, AST, ALT, MDA, and GPx were significantly higher; while, CAT significantly reduced in workers compared with controls. There was a significant correlation between AFB1/Alb and MDA level with the liver enzymes among both groups. CAT was inversely correlated with AFB1/Alb and the liver enzymes, and GPx was inversely correlated with AST in the workers. It was concluded that wood dust exposure is associated with raised serum levels of AFB1 and oxidative stress.

Acculturation, coping, and PTSD in Hispanic 9/11 rescue and recovery workers.

Objective: Research examining the responders of the World Trade Center terrorist attacks of 9/11 has found that Hispanic responders are at greater risk for posttraumatic stress disorder (PTSD) than non-Hispanic White responders. However, no studies have examined how acculturation may influence the relationship between coping and PTSD in Hispanic 9/11 responders. This novel study is the first to examine differences in coping and PTSD among Hispanic responders by level of acculturation. Methods: The sample is composed of 845 Hispanic 9/11 responders who were seen at the World Trade Center Health Program and participated in a web-based survey. Using logistic and multiple linear regression, we examined how acculturation is related to their coping strategies and risk for PTSD. We also tested for interaction to examine whether level of acculturation moderated the relationship between coping and PTSD symptom severity. Results: Key findings revealed that higher acculturation is associated with the use of substances, venting, and humor to cope, while lower acculturation is associated with the use of active coping and self-distraction in this sample. We also found that less acculturated responders were more likely to experience more severe PTSD. Lastly, our findings revealed that Hispanics who are more acculturated and used substances to cope had more severe PTSD than less acculturated responders. Conclusion: These findings highlight the need to consider the role of acculturation in Hispanic responders' coping and PTSD. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Racial and Ethnic Disparities Among COVID-19 Cases in Workplace Outbreaks by Industry Sector - Utah, March 6-June 5, 2020.

Improved understanding of the overall distribution of workplace coronavirus disease 2019 (COVID-19) outbreaks by industry sector could help direct targeted public health action; however, this has not been described. The Utah Department of Health (UDOH) analyzed COVID-19 surveillance data to describe workplace outbreaks by industry sectors. In this report, workplaces refer to non-health care, noncongregate-living, and noneducational settings. As of June 5, 2020, UDOH reported 277 COVID-19 outbreaks, 210 (76%) of which occurred in workplaces. Approximately 12% (1,389 of 11,448) of confirmed COVID-19 cases in Utah were associated with workplace outbreaks. The 210 workplace outbreaks occurred in 15 of 20 industry sectors;* nearly one half of all workplace outbreaks occurred in three sectors: Manufacturing (43; 20%), Construction (32; 15%) and Wholesale Trade (29; 14%); 58% (806 of 1,389) of workplace outbreak-associated cases occurred in these three sectors. Although 24% of Utah's workforce in all 15 affected sectors identified as Hispanic or Latino (Hispanic) or a race other than non-Hispanic white (nonwhite†) (1), 73% (970 of 1,335) of workplace outbreak-associated COVID-19 cases were in persons who identified as Hispanic or nonwhite. Systemic social inequities have resulted in the overrepresentation of Hispanic and nonwhite workers in frontline occupations where exposure to SARS-CoV-2, the virus that causes COVID-19, might be higher (2); extra vigilance in these sectors is needed to ensure prevention and mitigation strategies are applied equitably and effectively to workers of racial and ethnic groups disproportionately affected by COVID-19. Health departments can adapt workplace guidance to each industry sector affected by COVID-19 to account for different production processes and working conditions.

Heat related illness among workers in Washington State: A descriptive study using workers' compensation claims, 2006-2017.

BACKGROUND: Heat related illness (HRI) places a significant burden on the health and safety of working populations and its impacts will likely increase with climate change. The aim of this study was to characterize the demographic and occupational characteristics of Washington workers who suffered from HRI from 2006 to 2017 using workers' compensation claims data. METHODS: We used Washington workers' compensation data linked to weather station data to identify cases of work-related HRI. We utilized Occupational Injury and Illness Classification System codes, International Classification of Diseases 9/10 codes, and medical review to identify accepted and rejected Washington State (WA) workers' compensation claims for HRI from 2006 to 2017. We estimated rates of HRI by industry and evaluated patterns by ambient temperature. RESULTS: We detected 918 confirmed Washington workers' compensation HRI claims from 2006 to 2017, 654 were accepted and 264 were rejected. Public Administration had the highest third quarter rate (131.3 per 100 000 full time employees [FTE]), followed by Agriculture, Forestry, Fishing, and Hunting (102.6 per 100 000 FTE). The median maximum daytime temperature was below the Washington heat rule threshold for 45% of the accepted HRI claims. Latinos were estimated to be overrepresented in HRI cases. CONCLUSION: The WA heat rule threshold may not be adequately protecting workers and racial disparities are present in occupational HRI. Employers should take additional precautions to prevent HRI depending on the intensity of heat exposure. States without heat rules and with large industry sectors disproportionately affected by HRI should consider regulations to protect outdoor workers in the face of more frequent and extreme heat waves.

Neck/Shoulder Problems and Visual Disturbances Among Surgeons: A Scoping Review.

BACKGROUND: Minimally invasive surgeries are the surgical techniques that lower the size of incisions needed but may increase the physical problems such as neck/shoulder problems and visual disturbances among surgeons. This study aims to determine the prevalence, severity, proposed risk factors, and evidence for a relationship for neck/shoulder problems and visual disturbances (separately and concurrently) among surgeons. MATERIALS AND METHODS: A scoping review using the five-stage framework proposed by Arksey and O'Malley was conducted. This included identification of a research question and relevant studies, study selection, charting of data and collating, summarizing, and reporting of the results. Databases searched were PubMed, Embase, CINAHL, Cochrane Library and Web of Science, and Scopus, alongside a hand-search. An Appraisal tool for Cross-Sectional Studies was used to determine methodological quality of studies. RESULTS: Ten articles met the inclusion criteria from 744 identified. Prevalence were reported by all the studies and ranged from 6% to 74% (neck); 7%-35% (right shoulder); 8%-39% (left shoulder); 9%-80% (both shoulders), and 0.4%-63% (visual disturbances). Severity of these concerns was assessed in four studies and was variable. The risk factors for neck/shoulder problems and visual disturbances included workplace physical ergonomic factors, surgery factors, and surgeon-related factors. None of the included studies proposed a relationship between neck/shoulder problems and visual disturbances. CONCLUSIONS: There was great variability in the reported prevalence of neck/shoulder problems and visual disturbances among surgeons. Neck/shoulder problems and visual disturbances shared several risk factors, but the link between the two issues has not been fully investigated.

"Living like I am in Thailand": stress and coping strategies among Thai migrant masseuses in Oslo, Norway.

BACKGROUND: Migrants experience stress before, during and after migrating to a new country, all of which influences their mental wellbeing. In Norway, migration from Thailand is highly gendered as most Thai migrants are women who migrate to live with their Norwegian spouse. Massage shops, often owned by Thai entrepreneurs, are a locale where women use their cultural knowledge to bridge into the local economy. There is little knowledge about Thai migrant masseuses' experience of stress in daily life and associated coping strategies. The objective of this inquiry was to examine stressors and coping strategies among Thai migrant masseuses in Oslo, Norway. METHODS: We conducted in-depth interviews with 14 Thai migrants who were working as masseuses in Oslo, Norway. We asked participants about their health, experiences of stress, and coping strategies and subsequently analyzed the data using thematic analysis. RESULTS: Stress in participants' lives related to settling in, loneliness, finances and spousal relationships. Of these, relationship conflict was the largest source of stress. Women largely embraced self-coping strategies and utilized Thai cultural practices and Buddhist cognitive thinking. Once relationship conflict became untenable, participants fought to change their situation. Limited fluency in Norwegian, Thai stigma about mental health and limited knowledge of the Norwegian health system were barriers to seeking healthcare. CONCLUSIONS: Migrants in our study often adopted "Thainess", the use of Thai cultural practices and Buddhist cognitive thinking, as a strategy for coping with stress. Preferences for self-coping, mental health stigma, and linguistic competency are important considerations when designing mental wellbeing interventions for Thai women. Use of an interpreter or systems navigator can help overcome language barriers. Clinicians can take detailed case histories to better understand Thai patients' stress, coping strategies and wellbeing. Health policy makers could consider network approaches, including using Thai health systems navigators to bridge the health system and Thai communities.

"A Widespread Superstition": The Purported Invulnerability of Workers of Color to Occupational Heat Stress.

This study explores the history of the denial of the vulnerability of non-White workers to risks of heat illness. Defenders of chattel slavery argued for the capacity of workers of African descent to tolerate extreme environmental temperatures. In Hawai'i, advocates of racial segregation emphasized the perils to Whites of strenuous work in tropical climates and the advantages of using Chinese immigrants. Growing reliance on Mexican immigrants in agriculture and other outdoor employment in the early 20th century brought forth claims of their natural suitability for unhealthful working conditions. These efforts to naturalize racial hierarchy fell apart after 1930. The Great Depression subverted the notion that people of European descent could not endure hot work. More rigorous investigation refuted contentions of racial difference in heat tolerance.

Sleep quality and daytime sleepiness among Polish anaesthesiologists and intensivists.

PURPOSE: We aimed to investigate sleep quality (SQ), daytime sleepiness (DS), and their relation with subject- and work-related factors among Polish anaesthesiologists. METHODS: The study group comprised 786 anaesthesiologists. The Sleep Quality Scale (SQS) was applied in order to assess SQ, while excessive DS was evaluated using the Epworth Sleepiness Scale (ESS). RESULTS: The median score on the SQS was 31 (IQR 27-35) points. The median score on the ESS was 17 (IQR 13-20) points, with mild-to-moderate excessive DS found in 260 (33.1%) and severe excessive DS among 478 (60.8%) of those surveyed. Worse SQ was found in females; smokers; those who suffered from any chronic diseases; those who were receiving medication interfering with sleeping habits; those who were unsatisfied with their sleep; those who had a greater number of night shifts; and those who had a lower number of non-working days. A detrimental sleepiness pattern was determined by one's advanced age, the presence of any chronic diseases and lower satisfaction with one's sleep quantity. CONCLUSION: Poor SQ and excessive DS are frequently occurring phenomena. Since sleep disturbances are also related to the nature of their profession, the problem could be reduced by introducing organisational changes at work.

Work-Related Symptoms, Safety Concerns, and Health Service Utilization Among Korean and Chinese Nail Salon Workers in the Greater New York City Area.

The purpose of this study was to determine similarities and differences in health effects, safety concerns, and health service utilization among Korean and Chinese immigrant women working in nail salons in the Greater New York City area. In this cross-sectional study, analyses involved descriptive statistics, t tests, and χ2 tests. Koreans had longer work experience and more work-related health effects and concerns, but were less likely to use personal protective equipment than Chinese workers. Although Koreans reported better socioeconomic status than Chinese workers, they were less likely to have health care access and utilized less health services. To prevent prolonged exposure to toxic chemicals, nail salon employees need education regarding the importance of personal protective equipment use. Reducing structural barriers and increasing health care access for all nail salon workers are especially important in improving their health service utilization.

Update: Incidence of Glaucoma Diagnoses, Active Component, U.S. Armed Forces, 2013-2017.

Glaucoma is an eye disease that involves progressive optic nerve damage and vision loss, leading to blindness if undetected or untreated. This report describes an analysis using the Defense Medical Surveillance System to identify all active component service members with an incident diagnosis of glaucoma during the period between 2013 and 2017. The analysis identified 37,718 incident cases of glaucoma and an overall incidence rate of 5.9 cases per 1,000 person-years (p-yrs). The majority of cases (97.6%) were diagnosed at an early stage as borderline glaucoma; of these borderline cases, 2.2% progressed to open-angle glaucoma during the study period. No incident cases of absolute glaucoma, or total blindness, were identified. Rates of glaucoma were higher among non-Hispanic black (11.0 per 1,000 p-yrs), Asian/Pacific Islander (9.5), and Hispanic (6.9) service members, compared with non-Hispanic white (4.0) service members. Rates among female service members (6.6 per 1,000 p-yrs) were higher than those among male service members (5.8). Between 2013 and 2017, incidence rates of glaucoma diagnoses increased by 75.4% among all service members.

Trends in occupational injuries and diseases among Saudi and non-Saudi insured workers.

BACKGROUND: The ongoing industrial and infrastructural development in Saudi Arabia carries a high risk of occupational injuries/diseases. AIMS: To compare trends in occupational injuries and diseases among Saudi and non-Saudi insured workers. METHODS: We used the index values method and slope (S) calculation to analyse the occupational injuries/diseases trends from data in the annual statistical reports published by the General Organization for Social Insurance between 2004 and 2014. Data for 10 565 993 (18.5%) Saudi insured workers (SIWs) and 46 402 079 (81.5%) non-Saudi insured workers (NSIWs) and 896 627 occupational injuries/diseases were analysed. RESULTS: The distribution of incidences of occupational injuries/diseases among NSIWs (93.5%) was 14 times higher than that of SIWs (6.5%). Occupational injuries/diseases were more likely to increase among NSIWs than SIWs, particularly in the construction, trade, financing and real estate economic activities, and engineering, technicians and service workers occupations. There was a general decreasing trend in occupational injuries/diseases until 2013. CONCLUSIONS: Non-Saudi insured workers were at high risk of occupational injuries/diseases, therefore, implementation of an effective injury prevention programme is required.

[Prevalence of musculoskeletal disorders and related factors in female greenhouse workers in Shandong province].

Objective: To study the prevalence of musculoskeletal disorders (MSDs) and related factors in female greenhouse workers. Method: A questionnaire survey was conducted among 851 female greenhouse workers in Shandong province in 2015. Results: The incidence of MSDs among the female greenhouse workers was 82.79%. For the MSDs in female greenhouse workers, the top four affected body sites were low back (65.82%), knees (49.10%), neck (25.75%) and shoulder (23.47%). Multivariate logistic regression analysis showed that age ≥50 years (OR=2.098, 95%CI: 1.353-3.252), working years ≥20 (OR=1.703, 95%CI: 1.116-2.599), repetitive work (OR=1.903, 95%CI: 1.183-3.061), standing for prolonged time (OR=2.902, 95%CI: 1.183-7.120) and frequent slightly bending down (OR=2.979, 95%CI: 1.823-4.867) were the main risk factors for MSDs in female greenhouse workers. Aiding tools was the protective factor (OR=0.400, 95%CI:0.229-0.697). Conclusions: The findings showed a relatively higher prevalence of MSDs in female greenhouse workers. It is necessary to take appropriate measures to prevent and control the incidence of MSDs in female greenhouse workers.

Notch polymorphisms associated with sensitivity of noise induced hearing loss among Chinese textile factory workers.

BACKGROUND: Noise induced hearing loss (NIHL) is a polygenic disease involving both genetic and environmental factors, and is one of the most important occupational health hazards worldwide. To date, the influence of Notch1 variants on the risk to develop NIHL has not been illuminated. This study was conducted to explore the effects of Notch1 polymorphisms on individual susceptibility to NIHL. METHODS: A total of 2689 industrial workers from one textile factory in east China were recruited to participate in the current study. Venous blood was collected, basic clinical data was obtained by questionnaires and pure-tone audiometry (PTA) tests were conducted by specialist physicians. Next we performed genotyping of three selected SNPs (rs3124594, rs3124599 and rs3124603) in the Notch1 gene in 535 NIHL patients and 535 controls. Subsequently, the main effects of the genotypes and their interactions were evaluated. RESULTS: Our results revealed that individuals with a GG of rs3124594, TT of rs3124603 (OR = 4.70 and 1.59 respectively) and the haplotype AAC (rs3124594-rs3124599-rs3124603) (OR = 14.95) were associated with an increased risk of NIHL in our study cohort. Stratified analysis showed that an increased NIHL risk was found in individuals exposed to work related noise for ≤16 years that also had the rs3124594 GG or rs3124603 CT/TT genotype with an OR of 4.20 and 1.73 respectively. Multifactor dimensionality reduction analysis indicated that rs3124594, rs3124599 and rs3124603 interacted with each other and were related to an increased risk to develop NIHL (OR = 3.60). CONCLUSIONS: The genetic polymorphisms rs3124594 and rs3124603 within the Notch1 gene are associated with an increased risk of NIHL in a Chinese population and could potentially be used as biomarkers for NIHL in noise exposed workers.

Prevalence of and Factors Associated with Actinic Cheilitis in Extractive Mining Workers.

The objective of the present study was to determine the prevalence of actinic cheilitis among extractive mining workers and factors associated with the condition, especially the relationship between clinical appearance and the length of occupational exposure to sunlight. A cross-sectional study was performed in Dona Inês, Paraíba, Brazil between 2014 and 2015. A clinical examination, clinical photography and a questionnaire were applied to 201 extractive mining workers. The T-student's, ANOVA one-way, Fisher's exact and Pearson chi-squared tests were performed and the significance level was set at 5%. A high prevalence of actinic cheilitis was observed (38.8%). Length of occupational exposure to sunlight in months (169.63±112.68, p=0.002) was associated with actinic cheilitis. Most workers were Caucasian (p<0.001) and aged 37.41±12.15 years (p=0.004). The time of occupational exposure to sunlight was significant in relation to the following clinical features: atrophy (225.75±97.31; p=0.024); blurred demarcation between the vermilion border of the lip and the skin (186.68±113.15; p=0.032); vertical fissures (210.09±123.07; p=0.046); white and red spotting (199.51±91.80; p=0.004); hard consistency of the lip (225.81±122.34; p=0.012). A high prevalence of actinic cheilitis was found. Age and ethnicity were associated with the presence of AC. Severe clinical presentations of actinic cheilitis were found among participants who had worked for at least 185 months (approximately 15 years) exposed to the sun.

Resumo O objetivo foi determinar a prevalência de queilite actínica entre os trabalhadores extrativistas minerais e os fatores associados a esta lesão, principalmente a relação da aparência clínica da lesão com o tempo de exposição ocupacional à luz solar. Foi realizado um estudo transversal, entre 2014 e 2015, em Dona Inês / PB, localizado no Nordeste do Brasil. Foram aplicados um exame clínico, registro fotográfico e um questionário a 201 trabalhadores extrativistas minerais. Realizaram-se os testes "t" student, ANOVA, Exato de Fisher e Qui-quadrado de Pearson, o nível de significância foi de 5%. Observou-se alta prevalência de queilite actínica (38,8%). A duração da exposição ocupacional à luz solar, em meses, (169,63 ± 112,68, p = 0,002) foi associada à presença de queilite actínica. Estes trabalhadores eram, em sua maioria, brancos (p<0.001) com idade média de 37.41±12.15 anos (p=0.004). O tempo de exposição ocupacional à luz solar foi significativo em relação às seguintes características clínicas: atrofia (225,75 ± 97,31; p = 0,024); perda da demarcação entre o vermelhão do lábio e a borda da pele (186,68 ± 113,15; p = 0,032); Fissuras verticais (210,09 ± 123,07; p = 0,046); Manchas brancas e vermelhas (199,51 ± 91,80; p = 0,004); Consistência dura do lábio (225,81 ± 122,34; p = 0,012). Conclui-se que a prevalência de queilite actínica foi alta. A idade e a etnia foram fatores associados a presença de queilite actinica. Os participantes que haviam trabalhado pelo menos 185 meses (aproximadamente 15 anos) sob exposição ao sol, apresentaram manifestações clínicas graves da queilite actínica.

Prevalence and Risk Factors Associated with Self-Rated Morbidities Among South Asian Migrant Gas Station Workers in Kuwait.

Gas station workers (GSWs) are at elevated risk of morbidities associated with exposure to petrochemical substances. This cross-sectional study assessed the prevalence and examined demographics and occupation-related risk factors associated with self-rated ill-health among GSWs in Kuwait. Structured questionnaire was used to record self-rated ill-health from 460 selected GSWs of South-Asian origin. Prevalence of self-rated ill-health conditions was computed. Random-intercept multivariable logistic regression model was used to identify the demographics and/or work-place related potential risk factors associated with one or more morbidities. Prevalent morbidities were eye(s) complaint (45.2%), asthma/shortness of breath (7.6%), frequent sneezing and allergic rhinitis (44.3%), recurrent headache (48.3%), dizziness (9.8%), tremors (42%), and eczema/skin complaint (44.1%). Furthermore, GSWs were significantly more likely to report one or more ill-health conditions (vs. none), if they were overweight/obese (aOR 1.8; 95% CI 1.1-2.9), married (aOR 2.6; 95% CI 1.5-4.5) or on current job for more than one year (aOR 6.4; 95% CI 2.9-15.4). In conclusion, GSWs suffer from ailments of multiple organ systems and need education and facilitation for self-protection.
