Quality of life in retired workers with past exposure to asbestos.

BACKGROUND: Asbestos causes cancer and non-cancerous lung and pleural diseases and can also have a negative psychological impact but little is known about its effect on health-related quality of life. OBJECTIVES: The aim of this study is to describe the health-related quality of life (HRQoL) of retired men with a history of occupational exposure to asbestos and examine factors linked with low HRQoL. METHODS: Retired male workers of the French Asbestos-Related Disease Cohort (ARDCO) completed self-questionnaires that included SF-36v2 and HAD scales, questions about their perception of asbestos (perceived dangers and level of exposure, expectations to fall ill, or knowing someone who is) and their respiratory symptoms. Asbestos exposure was assessed by industrial hygienists. A perceived risk score was created using factorial analysis. Multivariable regressions were performed for all SF-36 subscales. RESULTS: A total of 1266 of 2075 questionnaires (61%) were returned complete and included in analysis. After adjustment for potential confounders, an increase in perceived risk score resulted in a decrease in physical component summary score (PCS), up to 10.7 points (p = 0.048) and in mental component summary score (MCS) (p = 0.044). Presence of respiratory symptoms was also associated with significantly decreased PCS and MCS (p < 0.001). Poor HRQoL was linked to higher perceived risk score with p ≤ 0.01 for all SF-36 dimensions. Asbestos exposure assessed by an expert was not associated with any outcome. CONCLUSIONS: All dimensions of HRQoL appear to be affected by the perceived risk of incurring asbestos-related disease and respiratory symptoms.

Anxious and depressive symptoms in the French Asbestos-Related Diseases Cohort: risk factors and self-perception of risk.

Background: Asbestos is known to be an independent risk factor for lung and pleural cancers. However, to date, little attention has been paid to the psychological effects of asbestos exposure among exposed subjects. The objectives of this study were to estimate the prevalence of anxious and depressive symptoms among >2000 French participants of the Asbestos-Related Diseases Cohort (ARDCO), 6 years after their inclusion, to identify the risk factors associated with those anxious and depressive symptoms and to evaluate the impact of the asbestos-risk perception. Methods: The ARDCO was constituted in four regions of France between October 2003 and December 2005, by including former asbestos workers. Between 2011 and 2012, participants of the ARDCO program were invited to undergo another chest CT scan 6 years after the previous scan. Participants were asked to complete questionnaires including asbestos exposure assessment, Hospital Anxiety and Depression Scale (HADS), asbestos-risk perception and self-perception of asbestos-related diseases. Results: Among the 2225 participants, 2210 fully completed questionnaires were collected and analyzed. The prevalence of symptoms of probable anxiety and probable depression was 19.7% and 9.9%, respectively. The risk of anxious and depressive symptoms was independently associated with self-perception of the intensity of asbestos exposure, asbestos-risk perception and self-perception of asbestos-related diseases. Conclusion: The results obtained in this large study confirm that previously asbestos-exposed subjects are likely to develop anxious and depressive symptoms. Finally, implications related to the prevention of anxiety and depression among asbestos-exposed workers is discussed.

Physical activity in people with asbestos related pleural disease and dust-related interstitial lung disease: An observational study.

This study aimed to measure the levels of physical activity (PA) in people with dust-related pleural and interstitial lung diseases and to compare these levels of PA to a healthy population. There is limited data on PA in this patient population and no previous studies have compared PA in people with dust-related respiratory diseases to a healthy control group. Participants with a diagnosis of a dust-related respiratory disease including asbestosis and asbestos related pleural disease (ARPD) and a healthy age- and gender-matched population wore the SenseWear(®) Pro3 armband for 9 days. Six-minute walk distance, Medical Outcomes Study 36-item short-form health survey and the Hospital Anxiety and Depression Scale were also measured. Fifty participants were recruited and 46 completed the study; 22 with ARPD, 10 with dust-related interstitial lung disease (ILD) and 14 healthy age-matched participants. The mean (standard deviation) steps/day were 6097 (1939) steps/day for dust-related ILD, 9150 (3392) steps/day for ARPD and 10,630 (3465) steps/day for healthy participants. Compared with the healthy participants, dust-related ILD participants were significantly less active as measured by steps/day ((mean difference 4533 steps/day (95% confidence interval (CI): 1888-7178)) and energy expenditure, ((mean difference 512 calories (95% CI: 196-827)) and spent significantly less time engaging in moderate, vigorous or very vigorous activities (i.e. >3 metabolic equivalents; mean difference 1.2 hours/day (95% CI: 0.4-2.0)). There were no differences in levels of PA between healthy participants and those with ARPD. PA was reduced in people with dust-related ILD but not those with ARPD when compared with healthy age and gender-matched individuals.

The role of social toxicity in responses to a slowly-evolving environmental disaster: the case of amphibole asbestos exposure in Libby, Montana, USA.

Experiencing a disaster has significant negative effects on psychological adjustment. Case study accounts point to two consistent trends in slowly-evolving environmental disasters: (a) patterns of negative social dynamics, and (b) relatively worse psychological outcomes than in natural disasters. Researchers have begun to explicitly postulate that the social consequences of slowly-evolving environmental disasters (e.g., community conflict) have their own effects on victims' psychological outcomes. This study tested a model of the relationship between those social consequences and psychological adjustment of victims of a slowly-evolving environmental disaster, specifically those whose health has been compromised by the amphibole asbestos disaster in Libby, MT. Results indicate that experiencing greater community conflict about the disaster was associated with greater family conflict about the disaster which, in turn, was associated with greater social constraints on talking with others about their disease, both directly and indirectly through experiencing stigmatization. Experiencing greater social constraints was associated with worse psychological adjustment, both directly and indirectly through failed social support. Findings have implications for understanding pathways by which social responses create negative effects on mental health in slowly-evolving environmental disasters. These pathways suggest points for prevention and response (e.g., social support, stigmatization of victims) for communities experiencing slowly-evolving environmental disasters.

Functional exercise capacity and health-related quality of life in people with asbestos related pleural disease: an observational study.

BACKGROUND: Functional exercise capacity in people with asbestos related pleural disease (ARPD) is unknown and there are no data on health-related quality of life (HRQoL). The primary aims were to determine whether functional exercise capacity and HRQoL were reduced in people with ARPD. The secondary aim was to determine whether functional exercise capacity was related to peak exercise capacity, HRQoL, physical activity or respiratory function. METHODS: In participants with ARPD, exercise capacity was measured by the six-minute walk test (6MWT) and incremental cycle test (ICT); HRQoL by the St George's Respiratory Questionnaire and physical activity by an activity monitor worn for one week. Participants also underwent lung function testing. RESULTS: 25 males completed the study with a mean (SD) age of 71 (6) years, FVC 82 (19)% predicted, FEV1/FVC 66 (11)%, TLC 80 (19)% predicted and DLCO 59 (13)% predicted. Participants had reduced exercise capacity demonstrated by six-minute walk distance (6MWD) of 76 (11)% predicted and peak work rate of 71 (21)% predicted. HRQoL was also reduced. The 6MWD correlated with peak work rate (r=0.58, p=0.002), St George's Respiratory Questionnaire Total score (r=-0.57, p=0.003), metabolic equivalents from the activity monitor (r=0.45, p<0.05), and FVC % predicted (r=0.52, p<0.01). CONCLUSIONS: People with ARPD have reduced exercise capacity and HRQoL. The 6MWT may be a useful surrogate measure of peak exercise capacity and physical activity levels in the absence of cardiopulmonary exercise testing and activity monitors.

Community-level social support responses in a slow-motion technological disaster: the case of Libby, Montana.

Social support is an important resource for communities experiencing disasters. However, a disaster's nature (rapid- versus slow-onset, natural versus technological) may influence community-level responses. Disaster research on social support focuses primarily on rapid-onset natural disasters and, to a lesser extent, rapid-onset technological disasters. Little research has addressed slow-onset disasters. This study explores social support processes in Libby, MT, a community experiencing a "slow-motion technological disaster" due to widespread amphibole asbestos exposure. A comprehensive social support coding system was applied to focus-group and in-depth-interview transcripts. Results reveal that, although the community has a history of normative supportiveness during community and individual crises, that norm has been violated in the asbestos disaster context. Results are interpreted as a failure to achieve an "emergent altruistic community." Specifically, community-level conflict appears to interfere with previously established social support patterns. The observed phenomenon can be understood as the deterioration of a previously supportive community.

Psychological Distress after a Diagnosis of Malignant Mesothelioma in a Group of Patients and Caregivers at the National Priority Contaminated Site of Casale Monferrato.

BACKGROUND: Patients of malignant mesothelioma (MM) and their caregivers face significant physical and psychological challenges. The purpose of the present study is to examine the emotional impact after the diagnosis of MM in a group of patients and familial caregivers in a National Priority Contaminated Site (NPCS). METHODS: A sample of 108 patients and 94 caregivers received a sociodemographic/clinical questionnaire, the Beck Depression Inventory II, the Davidson Trauma Scale, the Coping Orientation to the Problems Experienced-New Italian Version, and the Defense style questionnaire. The risk of depressive and post-traumatic stress disorder (PTSD) symptoms in relation to the strategies of coping and defense mechanisms was estimated in patients and caregivers separately by logistic regression models. RESULTS: For patients, a high risk of depression was associated with high usage of Defense Style Questionnaire (DSQ) Isolation (OR: 53.33; 95% CI: 3.22-882.30; p = 0.01) and DSQ Somatization (OR: 16.97; 95% CI: 1.04-275.90; p = 0.05). Other significant risks emerged for some coping strategies and some defenses regarding both depression and trauma in patients and caregivers. CONCLUSIONS: This research suggests that for both patients and caregivers unconscious adaptive processes have a central role in dealing with overwhelming feelings related to the disease.

[Psychological impacts of follow up for occupational asbestos exposure. Consequences after compensation for occupational disease in the SPP-A cohort]. / Impact psychologique du suivi post-professionnel amiante à long terme. Quelles conséquences après la déclaration suivie de la reconnaissance d'une maladie professionnelle chez des sujets de la cohorte SPP-A ?

INTRODUCTION: In France, long-term follow-up after occupational exposure to asbestos is recommended. This study looked at the psychological consequences in the longer term following a CT-scan, in particular the impact of having received compensation for an occupational disease. METHODS: As part of an asbestos post-exposure survey study (APExS), volunteers from Normandy were asked to complete self-assessment questionnaires about their psychological condition at different points during follow-up, including a psychological questionnaire before, then 6 months, and finally 18 to 24 months after their chest CT-scan. Information collected from 622 individuals were analyzed based on information provided as to the result of the screening and whether they had received compensation for having an occupational disease. RESULTS: The identification of an occupational disease eligible for compensation is associated with a long term increase in psychological distress. The impact of psychological state during follow-up is greater in men who reported receiving occupational disease compensation. The discovery of an asbestos-related disease during the screening is associated with a negative perception of general health and an increase in psychological distress. CONCLUSION: The receipt of compensation of an occupational disease does not seem to compensate for the negative psychological impact related to the discovery of a disease during the asbestos post-exposure follow-up.

Are the knowledge of non-malignant asbestos-related diseases and lung function impairment differentially associated with psychological well-being? A cross-sectional study in formerly asbestos-exposed workers in Germany.

OBJECTIVES: The knowledge of past asbestos exposure may lead to chronic psychological strain. In addition, the information about an increased cancer risk can place a psychological burden on individuals triggering mental health symptoms of depression or anxiety. This applies in particular to individuals with non-malignant asbestos-related disease (ARD) such as lung fibrosis and pleural thickening with or without lung function impairment. ARDs with or without lung function impairment may develop even years after exposure cessation. Therefore, the aim of the present study was to test for our cohort whether non-malignant ARD and lung function impairment have differential effects on mental health and psychological strain. DESIGN: Cross-sectional study. PARTICIPANTS AND SETTING: Overall, 612 male participants (mean age=66.2 years, SD=9.5) attending a surveillance programme for ARDs received routine examinations including lung function testing (24% refused to fill in the psychological questionnaire) at a German university hospital study centre from August 2008 to August 2013. OUTCOME MEASURES: Using multiple hierarchical regression analysis, ARD diagnosis and lung function impairment were used to predict psychological health as measured with validated questionnaires for depression and anxiety. Psychological strain was operationalised by intrusive thoughts and specific fear of cancer. RESULTS: The strongest predictor for mental health was obstructive functional impairment (eg, anxiety: ß=0.22, p<0.001). Psychological strain was predicted by the presence of a non-malignant ARD (eg, intrusive thoughts: ß=0.17, p=0.003). CONCLUSIONS: The presence of mental health symptoms is associated with ventilation disturbances, whereas the knowledge of an already initiated morphological change-caused by asbestos exposure-is primarily associated with psychological strain. Specifically, the affected individuals are more prone to intrusive thoughts and specific fear of asbestos-related cancer. As an implication, physicians should be sensitised about possible consequences of risk communication and functional impairment to counteract excessive fear or anxiety.

The asbestos worker who smokes: adding insult to injury.

Evaluates whether asbestos workers who smoke cigarettes, thereby increasing their cancer risk synergistically, differ from asbestos workers who choose not to smoke. Demographic, personality, psychologic, and cognitive differences were examined. Engaging in this highly detrimental health behavior was related exclusively to cognitive factors. Although current smokers were cognitively aware of their added health risk, in comparison to past and "never" smokers, they minimized the salience of awareness by fatalistically attributing their health to chance factors such as luck and by minimizing the dangers of smoking, the benefits of smoking cessation, and their own increased vulnerability to life-threatening illnesses. Results are explained in light of the apparent denial of risk. The need for physician intervention is strongly advocated.

Fall-off in reporting life events: effects of life change, desirability, and anticipation.

The influence of event characteristics on recall was examined by directly comparing fall-off in reporting life events as a function of life change, desirability, and anticipation. We collected information from a sample of 1,669 blue-collar workers on stressful life events that occurred in a 1-year interval before the questionnaire was administered. The results indicated no fall-off in reporting events associated with marked life changes (ie, salient events). In contrast, significant fall-off was observed for events characterized by varying degrees of desirability and anticipation. Although ratings of desirability and saliency were not independent, saliency of life events emerged as the dimension most closely associated with accuracy of event reporting. Research on the reliability of measures of life events and the association between event characteristics and illness should consider the kinds of systematic reporting differences observed here.

[Social impact of screening and of medical surveillance on people exposed to asbestos]. / L'impact social du dépistage et de la surveillance médicale chez les personnes exposées à l'amiante.

A medical screening program has collective and individual impact. The collective benefit of medical screening for people exposed to asbestos would be financial (better compensation of occupational diseases related to asbestos). The cost of compensation would be attributed to the special assurance fund for occupational diseases. A medical screening of asbestos diseases would set an example for other Public health problems. It would be important for admission of social damage for the French nation. For individuals, social benefits would be better (compensation during work stop and annuities). But screening can have a negative psychological impact for asymptomatic persons. Persons exposed to asbestos and patients with asbestos diseases are able to quit their job for anticipated retirement. Is it a benefit for patients with mesothelioma or lung cancer? It is a very important benefit for asbestosis. The risk is to change the objective of medical screening into a social screening. The financial and medical benefits of screening for hyaline plaques is very poor. Awarding social damage is important for individuals.

Adaptation of the questionnaire of Hahn, Cella, Bode, and Hanrahan in Spanish patients affected by asbestos poisoning.

The purpose of this study was to assess whether or not the questionnaire developed by Hahn, Cella, Bode, and Hanharan (2010) for use with cancer patients accurately measures the social well-being of individuals suffering from chronic illnesses associated with asbestos poisoning. One hundred ten male patients with asbestos poisoning were age-matched in blocks to a comparison group of 70 "healthy" controls, all of whom were current or retired employees of the largest naval company in Spain. The results indicate very high reliability of the Hahn et al. (2010) test to assess social well-being in these chronically ill patients, and a high concurrent validity of the measured outcomes with regard to results of the SCL-90 Derogatis questionnaire, especially on the social well-being dimensions of negative emotional support, negative social companionship, and satisfaction. Limitations of the study and possible future directions are discussed.

[What are the non-medical individual and collective objectives?]. / Quels sont les objectifs non médicaux individuels et collectifs ?

INDIVIDUAL NON-MEDICAL OBJECTIVES ARE: Information to patients concerning their past exposure to asbestos and their right to compensation; equity demands that every person potentially eligible should be fully informed. Social recognition. Facilitation of compensation by informing the patient and his physician of the mechanisms. COLLECTIVE NON-MEDICAL OBJECTIVES ARE: Social visibility, contributing to the prevention of occupational cancer. Better balance of the Social Security budget since it is the employers who bear the cost of compensation of occupational diseases. Improved epidemiological understanding of the circumstances of exposure and the most commonly concerned occupations and industries. Evaluation of the mechanisms of management of occupational diseases. PSYCHOLOGICAL IMPACT: It is of the same magnitude as any screening procedure; it should be acceptable and avoid long-term negative psychological effects; it may be useful to implement specific support for the few patients with psychological problems.

Hyperventilation in men claiming compensation for benign asbestos-related diseases.

The observation that hyperventilation was common in men involved in civil court actions compared with my non-medico-legal practice stimulated me to carefully assess 100 consecutively seen men with non-malignant asbestos-related disease(s). A diagnosis of hyperventilation was made in 33 and probable hyperventilation in 12. The development of anxiety symptoms in these men could, in part at least, be prevented or greatly decreased if more emphasis was placed on the education of ex-asbestos workers by solicitors and organisations responsible for the initiation of civil actions.

Reactions of asbestos-exposed workers to notification and screening.

In the wake of efforts to pass legislation mandating notification of workers at high risk of developing occupational disease, considerable controversy exists regarding the potential costs and benefits of such notification efforts. It has been suggested that individual notification would cause undue psychological distress, especially when primary prevention efforts are no longer possible. In this study, we assessed reactions of asbestos-exposed workers to a letter notifying them of their risk for asbestos-related illnesses and the availability of a medical screening program. Two hundred forty-seven workers who attended the screening program and 53 who chose not to attend completed a questionnaire that tapped reactions to notification. Workers reported neither undue psychological distress nor avoidance behavior in response to notification, and many respondents reported engaging in active and appropriate coping behaviors. Workers who first learned of their risk through the notification letter (33.7%) were no more likely to report distress or denial than were workers who had learned previously through other sources. Individuals who chose not to attend the screening program were less likely than attenders to report experiencing distress upon learning of their risk status, more likely to engage in minimization of risk, and less likely to have taken direct action. Our results suggest that the psychological costs of notifying workers of increased risk for asbestos-related illness appear to be outweighed by the benefits of notification and screening.

Effects of informing workers of their health risks from exposure to toxic materials.

This study compared the mental health, attitudes, and smoking behaviors of 133 workers who had been informed of health risks from exposure to toxic materials on the job with 137 workers who worked in similar conditions but who had not been told that their health was at risk because of exposure to toxic materials. The informed workers reported more health problems than controls, but there were no significant differences between the informed and uninformed groups in mental health, attitudes toward health hazards in or outside of the workplace, or in smoking rates. Ninety percent of all respondents felt that exposed workers definitely should be told of their health risks. These findings indicate little psychological risk from informing workers about their risks because of exposure to toxic substances and a strong desire on the part of workers to be informed.

Attorney-directed screenings can be hazardous.

BACKGROUND: The history of occupational health screenings indicate that they are often necessary to protect the health and interests of workers. However, medical screenings for asbestos and other occupational diseases which are organized and funded by attorneys may result in serious adverse outcomes to those screened. METHODS: We report a case of death that appears to have been heavily influenced by an attorney-initiated and -directed screening program. RESULTS: While well-run medical screening programs are essential to disease detection in workers, attorney-run and corporate screenings can be fraught with ethical and practical problems. Screenings have been used by corporations to identify workers with occupational illness in order to terminate their employment and avoid legal liability. Screenings can also be used to motivate workers to stop smoking and implement workplace controls. However, these screenings must be conducted responsibly. CONCLUSIONS: Although this is only one case it illustrates the gravity and potential danger of attorney-directed screening programs.
