The objective of the study was to examine diagnosis-specific sickness absences of different lengths as predictors of disability retirement in different occupational classes. Register-based prospective cohort study up to 8 years of follow-up. A 70% random sample of the non-retired Finnish population aged 25-62 at the end of 2006 was included (n=1 727 644) and linked to data on sickness absences in 2005 and data on disability retirement in 2007-2014. Cox proportional hazards regression was utilised to analyse the association of sickness absence with the risk of all-cause disability retirement during an 8-year follow-up. The risk of disability retirement increased with increasing lengths of sickness absence in all occupational classes. A long sickness absence was a particularly strong predictor of disability retirement in upper non-manual employees as among those with over 180 sickness absence days the HR was 9.19 (95% CI 7.40 to 11.40), but in manual employees the HR was 3.51 (95% CI 3.23 to 3.81) in men. Among women, the corresponding HRs were 7.26 (95% CI 6.16 to 8.57) and 3.94 (95% CI 3.60 to 4.30), respectively. Adjusting for the diagnosis of sickness absence partly attenuated the association between the length of sickness absence and the risk of disability retirement in all employed groups. A long sickness absence is a strong predictor of disability retirement in all occupational classes. Preventing the accumulation of sickness absence days and designing more efficient policies for different occupational classes may be crucial to reduce the number of transitions to early retirement due to disability. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Occupational health: a classic example of class conflict.

PubMed

Kerr, L E

1990-01-01

The history of class conflict in occupational health in the United States is illustrated by the current Pittston Company attack on coal miners' health benefits, the silicosis and asbestosis controversies, the corporate restrictions on state workers' compensation laws, and the unremitting management opposition to the federal Coal Mine Health and Safety Act of 1969 and the Occupational Health and Safety Act of 1970. A positive action program is presented as the basis for convening the long-overdue White House Conference on Occupational Health and Safety. Mining engineers are urged to support that action program to prevent unnecessary work-related death and disability.

While health inequalities among employees are well documented, their variation and determinants among employee subpopulations are poorly understood. We examined variations in occupational class inequalities in health within four employment sectors and the contribution of working conditions to these inequalities. Cross-sectional data from the Helsinki Health Study in 2000-2002 were used. Each year, employees of the City of Helsinki, aged 40-60 years, received a mailed questionnaire (n = 8,960, 80% women, overall response rate for 3 years 67%). The outcome was physical health functioning measured by the overall physical component summary of SF-36. The socioeconomic indicator was occupational social class. Employment sectors studied were health care, education, social welfare and administration (n = 6,557). Physical and mental workload, and job demands and job control were explanatory factors. Inequality indices from logistic regression analysis were calculated. Occupational class inequalities in physical health functioning were slightly larger in education (1.47) than in the other sectors (1.43-1.40). Physical workload explained 95% of inequalities in social welfare and 32-36% in the other sectors. Job control also partly explained health inequalities. However, adjusting for mental workload and job demands resulted in larger health inequalities. Inequalities in physical health functioning were found within each employment sector, with minor variation in their magnitude. Physical workload was the main explanation for these inequalities, but its contribution varied between the sectors. In contrast, considering psychosocial working conditions led to wider inequalities. Improving physical working conditions among the lower occupational classes would help reduce health inequalities within different employment sectors.

Objectives We aimed to provide previously unestablished information on population-based differences in cause-specific sickness absence trends between occupational classes and further between four large industrial sectors within the different occupational classes while controlling for other socioeconomic factors and employment patterns. We focused on the period 2005–2013, during which the labour market underwent large economic and structural changes in many countries. Design Register-based panel data study. Setting Large representative datasets on Finnish wage earners aged 25–59 years. Outcome measure Annual risk of sickness absence (>10 working days) based on repeated logistic regression. Results Between 2005 and 2013, the proportion of employees with sickness absence decreased. Occupational class differences in sickness absence trends varied by disease group. Overall, the decrease in absences was smallest among lower non-manual employees. Sickness absence levels were highest in the health and social work sector and in the manufacturing sector within the non-manual and manual classes, respectively. Absences due to musculoskeletal diseases decreased temporarily during the peak of the economic recession in 2009, particularly in the manufacturing sector within the manual class. The decrease in absences due to musculoskeletal diseases was smallest in the trade sector within the lower occupational classes. Overall, education, income and employment patterns partly explained the differences in the absence levels, but not in the trends. Conclusions We found a complex interplay between the associations of occupational class and industrial sector with sickness absence trends. During the economic recession, absences due to musculoskeletal diseases decreased temporarily in a segment of wage earners who were known to have been hit hard by the recession. However, the trend differences were not explained by the measured structural changes in the characteristics of the study

Study objective Education, income, and occupational class are often used interchangeably in studies showing social inequalities in health. This procedure implies that all three characteristics measure the same underlying phenomena. This paper questions this practice. The study looked for any independent effects of education, income, and occupational class on four health outcomes: diabetes prevalence, myocardial infarction incidence and mortality, and finally all cause mortality in populations from Sweden and Germany. Design Sweden: follow up of myocardial infarction mortality and all cause mortality in the entire population, based on census linkage to the Cause of Death Registry. Germany: follow up of myocardial infarction morbidity and all cause mortality in statutory health insurance data, plus analysis of prevalence data on diabetes. Multiple regression analyses were performed to calculate the effects of education, income, and occupational class before and after mutual adjustments. Setting and participants Sweden (all residents aged 25–64) and Germany (Mettman district, Nordrhein‐Westfalen, all insured persons aged 25–64). Main results Correlations between education, income, and occupational class were low to moderate. Which of these yielded the strongest effects on health depended on type of health outcome in question. For diabetes, education was the strongest predictor and for all cause mortality it was income. Myocardial infarction morbidity and mortality showed a more mixed picture. In mutually adjusted analyses each social dimension had an independent effect on each health outcome in both countries. Conclusions Education, income, and occupational class cannot be used interchangeably as indicators of a hypothetical latent social dimension. Although correlated, they measure different phenomena and tap into different causal mechanisms. PMID:16905727

Background. The Self-Reporting Questionnaire (SRQ-20) is widely used for evaluating common mental disorders. However, few studies have evaluated the SRQ-20 measurements performance in occupational groups. This study aimed to describe manifestation patterns of common mental disorders symptoms among workers populations, by using latent class analysis. Methods. Data derived from 9,959 Brazilian workers, obtained from four cross-sectional studies that used similar methodology, among groups of informal workers, teachers, healthcare workers, and urban workers. Common mental disorders were measured by using SRQ-20. Latent class analysis was performed on each database separately. Results. Three classes of symptoms were confirmed in the occupational categories investigated. In all studies, class I met better criteria for suspicion of common mental disorders. Class II discriminated workers with intermediate probability of answers to the items belonging to anxiety, sadness, and energy decrease that configure common mental disorders. Class III was composed of subgroups of workers with low probability to respond positively to questions for screening common mental disorders. Conclusions. Three patterns of symptoms of common mental disorders were identified in the occupational groups investigated, ranging from distinctive features to low probabilities of occurrence. The SRQ-20 measurements showed stability in capturing nonpsychotic symptoms. PMID:27630999

2011-01-01

Background The social gradient in disability pension is well recognized, however mechanisms accounting for the gradient are largely unknown. The aim of this study was to examine the association between occupational class and subsequent disability pension among middle-aged men and women, and to what extent work-related factors accounted for the association. Methods A subsample (N = 7031) of the population-based Hordaland Health Study (HUSK) conducted in 1997-99, provided self-reported information on health and work-related factors, and were grouped in four strata by Erikson, Goldthorpe and Portocareros occupational class scheme. The authors obtained follow-up data on disability pension by linking the health survey to national registries of benefit (FD-trygd). They employed Cox regression analysis and adjusted for gender, health (medical conditions, mental health, self-perceived health, somatic symptoms) and work-related factors (working hours, years in current occupation, physical demands, job demands, job control). Results A strong gradient in disability pension by occupational class was found. In the fully adjusted model the risk (hazard ratio) ranged from 1.41 (95% CI 0.84 to 2.33) in the routine non-manual class, 1.87 (95% CI 1.07 to 3.27) in the skilled manual class and 2.12 (95% CI 1.14 to 3.95) in the unskilled manual class, employing the administrator and professional class as reference. In the gender and health-adjusted model work-related factors mediated the impact of occupational class on subsequent disability pension with 5% in the routine non-manual class, 26% in the skilled manual class and 24% in the unskilled manual class. The impact of job control and physical demands was modest, and mainly seen among skilled and unskilled manual workers. Conclusions Workers in the skilled and unskilled manual classes had a substantial unexplained risk of disability pension. Work-related factors only had a moderate impact on the disability risk.

This study aimed to examine the long-term changes and socioeconomic disparities in hospitalization for affective and neurotic disorders among the Finnish working-age population from 1976 to 2010. Register-based study, consisting of a 5-year follow-up of 3,223,624 Finnish working-age (18-64-year old) individuals in seven consecutive cohorts. We calculated the hazard ratios of psychiatric hospitalization for different occupational classes using Cox regression models. The risk of hospitalization for affective and neurotic disorders increased in all occupational classes after the economic recession in the 1990s, and then decreased in the 2000s. Before the 2000s, the risk was the highest among manual workers. In the 2000s the disparities between upper-level non-manual employees and other occupational classes increased. Hospitalization rates remained high among female manual workers and non-manual lower-level employees. This study revealed important similarities and differences between occupational classes in terms of long-term changes in hospitalization for affective and neurotic disorders. The results suggest that the labor market changes and healthcare reforms during the 1990s and 2000s in Finland have been more beneficial for higher than for lower occupational classes.

Occupational conditions, together with socioeconomic status, may modulate sleep. This study examined the association of occupational conditions and socioeconomic status with actigraphic measures of sleep in workers. Fifty-five employees (40 ± 12 years) wore a wrist actigraph during sleep for seven consecutive nights. Sleep variables addressed included total sleep time, sleep efficiency, mean activity during sleep, sleep-onset latency, and wake after sleep onset. We also measured household income, occupational class, work schedule, weekly work hours, job demand, job control, worksite social support, effort-reward imbalance, organizational justice, and workplace social capital. Multiple linear regression models were used to determine the association of occupational indicators, socioeconomic status, as well as age and gender with each sleep variable. Higher workplace social capital was associated consistently with longer total sleep time (P < 0.001), higher sleep efficiency (P < 0.05) and lower mean activity during sleep (P < 0.07). Low occupational class (P < 0.01), higher job demand (P < 0.05) and lower job control (P < 0.05) were associated with longer total sleep time. No associations were significant for sleep-onset latency or wake after sleep onset. These preliminary results suggest that enhanced workplace social capital is closely associated with better quality and quantity of sleep. © 2014 European Sleep Research Society.

A low socioeconomic position (SEP) is consistently associated with ill health, sickness absence (SA) and permanent disability, but studies among young employees are lacking. We examined the interrelationships between education, occupational class and income as determinants of SA among 25-34-year-old employees. We also examined, whether the association between SEP and SA varied over time in 2002-2007 and 2008-2013. The analyses covered young, 25-34-year-old women and men employed by the City of Helsinki over the time periods 2002-2007 and 2008-2013. Four-level education and occupational class classifications were used, as well as income quartiles. The outcome measure was the number of annual SA days. Education had the strongest and most consistent independent association with SA among women and men in both periods under study. Occupational class had weaker independent and less consistent association with SA. Income had an independent association with SA, which strengthened over time among the men. The interrelationships between the SEP indicators and SA were partly explained by prior or mediated through subsequent SEP indicators. Socioeconomic differences followed only partially a gradient for occupational class and also for income among men. Preventive measures to reduce the risk of SA should be considered, especially among young employees with a basic or lower-secondary education.

‘Like Skydiving without a Parachute’: How Class Origin Shapes Occupational Trajectories in British Acting

Friedman, Sam; O’Brien, Dave; Laurison, Daniel

2016-01-01

There is currently widespread concern that access to, and success within, the British acting profession is increasingly dominated by those from privileged class origins. This article seeks to empirically interrogate this claim using data on actors from the Great British Class Survey (N = 404) and 47 qualitative interviews. First, survey data demonstrate that actors from working-class origins are significantly underrepresented within the profession. Second, they indicate that even when those from working-class origins do enter the profession they do not have access to the same economic, cultural and social capital as those from privileged backgrounds. Third, and most significantly, qualitative interviews reveal how these capitals shape the way actors can respond to shared occupational challenges. In particular we demonstrate the profound occupational advantages afforded to actors who can draw upon familial economic resources, legitimate embodied markers of class origin (such as Received Pronunciation) and a favourable typecasting.

This article compares different proposals for the implementation of the concept of social class and analyzes the alternatives used in each proposal, considering previous epidemiological studies on this issue and the potential of such a concept as a central category in studies on social determination in the health/disease process. Seven basic differences were identified, pertaining to the following aspects: class structure; research objective; the social class concept as a reference; the decision as to which individual has his/her occupational activity taken as defining the family's social class; the class status of the unemployed, housewives, and the retired; class status of students; and criteria for distinguishing between the "bourgeoisie", "petty bourgeoisie", "new petty bourgeoisie", and "proletariat" and whether there is a specific flow in certain population groups. Given the observed differences and underlying theoretical models, this study discusses problems related to the fact that the use of a specific concept of social class can have various implementation models.

In Spain, the new National Classification of Occupations (Clasificación Nacional de Ocupaciones [CNO-2011]) is substantially different to the 1994 edition, and requires adaptation of occupational social classes for use in studies of health inequalities. This article presents two proposals to measure social class: the new classification of occupational social class (CSO-SEE12), based on the CNO-2011 and a neo-Weberian perspective, and a social class classification based on a neo-Marxist approach. The CSO-SEE12 is the result of a detailed review of the CNO-2011 codes. In contrast, the neo-Marxist classification is derived from variables related to capital and organizational and skill assets. The proposed CSO-SEE12 consists of seven classes that can be grouped into a smaller number of categories according to study needs. The neo-Marxist classification consists of 12 categories in which home owners are divided into three categories based on capital goods and employed persons are grouped into nine categories composed of organizational and skill assets. These proposals are complemented by a proposed classification of educational level that integrates the various curricula in Spain and provides correspondences with the International Standard Classification of Education.

Objective To evaluate Job Content Questionnaire(JCQ) performance using the latent class model. Methods We analysed cross-sectional studies conducted in Brazil and examined three occupational categories: petroleum industry workers (n=489), teachers (n=4392) and primary healthcare workers (3078)and 1552 urban workers from a representative sample of the city of Feira de Santana in Bahia, Brazil. An appropriate number of latent classes was extracted and described each occupational category using latent class analysis, a multivariate method that evaluates constructs and takes into account the latent characteristics underlying the structure of measurement scales. The conditional probabilities of workers belonging to each class were then analysed graphically. Results Initially, the latent class analysis extracted four classes corresponding to the four job types (active, passive, low strain and high strain) proposed by the Job-Strain model (JSM) and operationalised by the JCQ. However, after taking into consideration the adequacy criteria to evaluate the number of extracted classes, three classes (active, low strain and high strain) were extracted from the studies of urban workers and teachers and four classes (active, passive, low strain and high strain) from the study of primary healthcare and petroleum industry workers. Conclusion The four job types proposed by the JSM were identified among primary healthcare and petroleum industry workers—groups with relatively high levels of skill discretion and decision authority. Three job types were identified for teachers and urban workers; however, passive job situations were not found within these groups. The latent class analysis enabled us to describe the conditional standard responses of the job types proposed by the model, particularly in relation to active jobs and high and low strain situations.

To investigate and compare the influence of social and cultural factors as access barriers to oral health care amongst people from various social classes. A cross sectional survey in Pimpri, was conducted using a pilot tested 15 item-structured, close-ended and self-administered questionnaire. Two hundred and fifty people aged 35-45 years (50 participants each in five social classes as per British Registrar's General classification of occupation) were selected. The chi-square test was applied to check statistical differences between social classes at 5% level of significance. Overall, it was observed that irrespective of the social class difference 88% participants wished to seek only expert/professional advice for the dental treatment. Unavailability of services on Sunday (63%), going to dentist only when in pain (57%), trying self care or home remedy (54%), inadequate government policies (50%), budgetary constraints (40%) were among the major access barriers. Statistically significant difference in the access barriers among the social classes were found related to: Inadequate government policies, budgetary constraints, appointment schedules, far-off located clinics, myths and fear about dental treatment. Social and cultural factors act as access barriers to oral health care and social class differences have a significant influence on the access barriers.

Few studies have compared water exposure between different occupations in the general population. To investigate and compare the extent of occupational water exposure, with a focus on service, healthcare and production occupations previously classified as involving a high risk for hand eczema. In two public health surveys (2006 and 2010), a validated question regarding occupational water exposure was answered by 18 342 and 15,736 gainfully employed individuals, respectively. Exposure for ≥ 0.5 h/day was reported by 17.5% and 16.3% (p = 0.020) for the respective years, and exposure for > 2 h/day by 7.8% and 7.7% (p = 0.73). Exposure in women was almost twice as high as in men for both years (p ≤ 0.001) and exposure levels (p < 0.001). Exposure for > 2 h/day was more common in high-risk occupations in service and healthcare than in non-high-risk occupations [prevalence proportion ratios of 16.7 (95%CI: 14.0-20.0) and 8.3 (95%CI: 6.9-9.9), respectively]. Exposure was highest in service occupations, where 44.6% reported exposure for > 2 h/day in 2010, and kitchen work, cleaning and hairdressing dominated. In healthcare, the corresponding figure was 22.0%. Challenging differences in water exposure between occupational groups were found, and extensive water exposure was reported in a number of occupations previously classified as involving a high risk for hand eczema. © 2015 John Wiley & Sons A/S.

This study aimed to analyse the existence of an association between social class (categorized by type of occupation) and the occurrence of A(H1N1)pmd09 infection and hospitalization for two seasons (2009-2010 and 2010-2011). This multicentre study compared ambulatory A(H1N1)pmd09 confirmed cases with ambulatory controls to measure risk of infection, and with hospitalized A(H1N1)pmd09 confirmed cases to asses hospitalization risk. Study variables were: age, marital status, tobacco and alcohol use, pregnancy, chronic obstructive pulmonary disease, chronic respiratory failure, cardiovascular disease, diabetes, chronic liver disease, body mass index >40, systemic corticosteroid treatment and influenza vaccination status. Occupation was registered literally and coded into manual and non-manual worker occupational social class groups. A conditional logistic regression analysis was performed. There were 720 hospitalized cases, 996 ambulatory cases and 1062 ambulatory controls included in the study. No relationship between occupational social class and A(H1N1)pmd09 infection was found [adjusted odds ratio (aOR) 0·97, 95% confidence interval (CI) 0·74-1·27], but an association (aOR 1·53, 95% CI 1·01-2·31) between occupational class and hospitalization for A(H1N1)pmd09 was observed. Influenza vaccination was a protective factor for A(H1N1)pmd09 infection (aOR 0·41, 95% CI 0·23-0·73) but not for hospitalization. We conclude that manual workers have the highest risk of hospitalization when infected by influenza than other occupations but they do not have a different probability of being infected by influenza.

Meta-data data routinely collected through the Collaborative Social Media Observatory (COSMOS: http://www.cosmosproject.net/) relating to UK Twitter users is matched with the occupational lookup tables between job and social class provided by the Office for National Statistics (ONS) using SOC2010. Using expert human validation, the validity and reliability of the automated matching process is critically assessed and a prospective class distribution of UK Twitter users is offered with 2011 Census baseline comparisons. The pattern matching rules for identifying age are explained and enacted following a discussion on how to minimise false positives. The age distribution of Twitter users, as identified using the tool, is presented alongside the age distribution of the UK population from the 2011 Census. The automated occupation detection tool reliably identifies certain occupational groups, such as professionals, for which job titles cannot be confused with hobbies or are used in common parlance within alternative contexts. An alternative explanation on the prevalence of hobbies is that the creative sector is overrepresented on Twitter compared to 2011 Census data. The age detection tool illustrates the youthfulness of Twitter users compared to the general UK population as of the 2011 Census according to proportions, but projections demonstrate that there is still potentially a large number of older platform users. It is possible to detect “signatures” of both occupation and age from Twitter meta-data with varying degrees of accuracy (particularly dependent on occupational groups) but further confirmatory work is needed.

Objectives: Occupational injuries remain an important unresolved issue in many of the developing and developed countries. We aimed to outline the causes, characteristics, measures and impact of occupational injuries among different ethnicities. Materials and Methods: We reviewed the literatures using PUBMED, MEDLINE, Google Scholar and EMBASE search engine using words: “Occupational injuries” and “workplace” between 1984 and 2014. Results: Incidence of fatal occupational injuries decreased over time in many countries. However, it increased in the migrant, foreign born and ethnic minority workers in certain high risk industries. Disproportionate representations of those groups in different industries resulted in wide range of fatality rates. Conclusions: Overrepresentation of migrant workers, foreign born and ethnic minorities in high risk and unskilled occupations warrants effective safety training programs and enforcement of laws to assure safe workplaces. The burden of occupational injuries at the individual and community levels urges the development and implementation of effective preventive programs. PMID:27051619

Minimum visual requirements in different occupations in Finland.

PubMed

Aine, E

1984-01-01

In Finland the employers can individually fix the minimum visual requirements for their personnel in almost every occupation. In transportation, in police and national defence proper eyesight is regarded so important that strict visual requirements for these have been fixed by the Government. The regulations are often more close when accepting the person to the occupation than later on when working. The minimum requirements are mostly stated for visual acuity, colour perception and visual fields. In some occupations the regulations concern also the refractive error of the eyes and possible eye diseases. In aviation the regulations have been stated by the International Civil Aviation Organization ( ICAO ). The minimum visual requirements for a driving license in highway traffic are classed according to the types of motor vehicles. In railways , maritime commerce and national defence the task of the worker determines the specified regulations. The policeman must have a distant visual acuity of 0.5 without eyeglasses in both eyes and nearly normal colour perception when starting the training course.

Differences and similarities in therapeutic mode use between occupational therapists and occupational therapy students in Norway.

The Intentional Relationship Model (IRM) is a new model of the therapeutic relationship in occupational therapy practice. Two previous studies have focused on therapist communication style, or 'mode' use, but to date no group comparisons have been reported. To explore differences between occupational therapists and occupational therapy students with regard to their therapeutic mode use. The study had a cross-sectional design, and convenience samples consisting of occupational therapists (n = 109) and of second-year occupational therapy students (n = 96) were recruited. The Self-Assessment of Modes Questionnaire was the main data collection tool. Group differences were analysed with independent t-tests. The occupational therapists responded more within the collaborative and empathizing modes than the students did. The students responded more within the advocating and instructing modes than the occupational therapists did. There may be systematic differences between occupational therapists and students concerning their therapeutic mode use. Some modes, such as the collaborating and empathizing modes, may be viewed as requiring more experience, whereas other modes, such as the advocating mode may be related to more recent rehabilitation ideologies. These factors may contribute to explaining several of the group differences observed.

Impact of Obesity on Work Productivity in Different US Occupations: Analysis of the National Health and Wellness Survey 2014 to 2015.

PubMed

Kudel, Ian; Huang, Joanna C; Ganguly, Rahul

2018-01-01

The aim of this study was to quantify the relationship between workers' body mass index and work productivity within various occupations. Data from two administrations (2014 and 2015) of the United States (US) National Health and Wellness Survey, an Internet-based survey administered to an adult sample of the US population, were used for this study (n = 59,772). Occupation was based on the US Department of Labor's 2010 Standardized Occupation Codes. Outcomes included work productivity impairment and indirect costs of missed work time. Obesity had the greatest impact on work productivity in Construction, followed by Arts and Hospitality occupations. Outcomes varied across occupations; multivariable analyses found significant differences in work productivity impairment and indirect costs between normal weight and at least one obesity class. Obesity differentially impacted productivity and costs, depending upon occupation.

The natural history of insomnia symptomatology is poorly understood. Cross-sectional associations have been demonstrated among socioeconomic disadvantage, female sex, and poor sleep but it is unclear how these social factors predict patterns of insomnia symptoms over time. The aim of this article is to describe longitudinal patterns of insomnia symptoms as people age and investigate how they vary by sex and occupational class. A prospective cohort study with 20 yr of follow-up from 1987 to 1988. West of Scotland. One cohort approximately 36 yr of age at baseline aging to 57 yr (n = 1,444), and another aging from approximately 56 to 76 yr (n = 1,551). N/A. At approximately 5-yr intervals, respondents self-reported trouble initiating and maintaining sleep. Latent class analysis identified 4 main sleep patterns: a healthy pattern with little sleeping trouble across the 20 yr; an episodic pattern, characterized by trouble maintaining sleep; a chronic pattern with trouble maintaining and initiating sleep throughout the study; and a pattern where symptoms developed during the 20-yr follow-up. Chronic patterns were more likely in the older cohort than the younger one, for women than men in the older cohort, and for those from a manual rather than a nonmanual occupational class in both cohorts. In the middle-aged cohort a developing pattern was more likely for women than men. Chronic symptoms, characterized by both trouble maintaining and initiating sleep, are patterned by social factors.

Health risks, social relations and class: an analysis of occupational health discourse in Finnish newspaper and women's magazine articles 1961-2008.

Varje, Pekka; Väänänen, Ari

2016-03-01

In this article we examine the treatment of psychosocial risks in public occupational health discourse in Finnish newspaper and magazine articles between the 1960s and 2000s, using discourse analysis. Building on class theories, our aim is to investigate how class expectations have been linked with the redefinition of occupational health risks during this period. Our results suggest that as social relations at the workplace became problematised in the occupational health discussions after the 1970s, the image of the hierarchical and naturally conflictual organisation was replaced by idealised middle-class notions of smoothly functioning, harmonious organisations that offered rewarding work experiences. However, this same period since the late 1970s has also been characterised by increasing economic competition and neoliberal market ideology. We conclude that the concern about work-related psychosocial risks and health problems expressed in Finnish newspaper and magazine articles during the last three decades has been shaped in many respects by a collision between the dominant middle-class expectations of harmony and equality and the neoliberal production of competition and inequality. © 2015 Foundation for the Sociology of Health & Illness.

Social closure, micro-class immobility and the intergenerational reproduction of the upper class: a comparative study.

PubMed

Ruggera, Lucia; Barone, Carlo

2017-06-01

This article assesses how processes of social closure enhance intergenerational immobility in the regulated professions and thus promote persistence at the top of the occupational hierarchy. We compare four European countries (GB, Germany, Denmark and Sweden) that differ considerably in their degree of professional regulation and in their broader institutional arrangements. We run log-linear and logistic regression models on a cumulative dataset based on three large-scale surveys with detailed and highly comparable information at the level of unit occupations. Our analyses indicate that children of licensed professionals are far more likely to inherit the occupation of their parents and that this stronger micro-class immobility translates into higher chances of persistence in the upper class. These results support social closure theory and confirm the relevance of a micro-class approach for the explanation of social fluidity and of its cross-national variations. Moreover, we find that, when children of professionals do not reproduce the micro-class of their parents, they still display disproportionate chances of persistence in professional employment. Hence, on the one hand, processes of social closure erect barriers between professions and fuel micro-class immobility at the top. On the other hand, the cultural proximity of different professional groups drives intense intergenerational exchanges between them. Our analyses indicate that these micro- and meso-class rigidities work as complementary routes to immobility at the top. © London School of Economics and Political Science 2017.

To evaluate the occupational safety climate in different types of enterprises and its relationship with occupational accidental injury. A cross-sectional survey based on self-report questionnaires was performed among 3311 front-line workers from 54 medium and small-sized manufacturing enterprises of different types in Zhongshan, China to investigate the socio-demographic characteristics, safety climate experience in workplace, and incidence of occupational accidental injury in the past year. Analysis of the data revealed that employees in different types of companies perceived different levels of safety climate, according to the scores on four subscales; the European and American enterprises had significantly better safety climate than the Hong Kong and Chinese private enterprises (P < 0.01). The self-reported rates of occupational injury were 3.38%, 4.76%, and 6.72%, respectively, for European and American, Hong Kong, and Chinese private enterprises (χ(2) = 6.78, P < 0.05). After control of such factors as age, sex, income, education level, and marriage, the logistic regression analysis showed that the risk of occupational accidental injury in the European and American enterprises was significantly lower than that in the Chinese private enterprises (OR = 0.57, 95%CI = 0.35-0.91). The type of enterprise influences the occupational safety climate and incidence of occupational injury among workers.

Permanent work incapacity, mortality and survival without work incapacity among occupations and social classes: a cohort study of ageing men in Geneva.

Gubéran, E; Usel, M

1998-12-01

The objective of this retrospective cohort study was to investigate the burden of disability and death in men, from middle age to age of retirement, among occupational groups and classes in Geneva. Men were included if they resided in the Canton of Geneva, were 45 years of age in 1970-1972, and were not receiving a disability pension at the start of the follow-up. The cohort of 5137 men was followed up for 20 years and linked to national registers of disability pension allowance and of causes of death. There was a steep upward trend in incidence of permanent work incapacity with lower social class for all causes as well as for the seven causes of disability studied. Compared with professional occupations (social class I), the relative risk (RR) of permanent work incapacity was 11.4 for partly skilled and unskilled occupations (class IV+V) (95% confidence interval [CI]: 5.2-28.0). The social class gradient in mortality was in the same direction as that in work incapacity although much less steep (RR class IV+V to class I = 1.6, 95% CI : 1.1-2.2). Survival without work incapacity at the time of the 65th birthday ranged from only 57% in construction workers and labourers to 89% in science and related professionals. Unemployment in Geneva was below 1.5% during almost all the study period. Medically-ascertained permanent work incapacity and survival without work incapacity have shown considerably greater socioeconomic differentials than the mortality differentials.

Heubel, F

2014-08-01

Healthcare requires careful coordination of several occupations. In order to attain the best possible result, including effectiveness and cost-efficiency, the specific expertise of each of these occupations must be clearly defined. Healthcare occupations, physicians and nurses, are indeed professions as opposed to mere "jobs". They are concerned with living but ill human beings and not with things. Reliance on a personal capacity of judgment is a decisive aspect of professions. Healthcare professionals perform best if they are granted specific independence relative to their work.

To compare different measures of socioeconomic position (SEP) and occupational social class (OSC) and to evaluate their association with risky alcohol consumption among adolescents attending the last mandatory secondary school (ages 15-17 years). This was a cross-sectional study. 1268 adolescents in Catalonia (Spain) participated in the study. Family affluence scale (FAS), parents' OSC, parents' level of education and monthly familiar income were used to compare socioeconomic indicators. Logistic regression analyses were conducted to evaluate socioeconomic variables and missing associated factors, and to observe the relation between each SEP variable and OSC adjusting by sociodemographic variables. Familiar income had more than 30% of missing values. OSC had the fewest missing values associated factors. Being immigrant was associated with all SEP missing values. All SEP measures were positively associated with risky alcohol consumption, yet the strength of these associations diminished after adjustment for sociodemographic variables. Weekly available money was the variable with the strongest association with risky alcohol consumption. OSC seems to be as good as the other indicators to assess adolescents' SEP. Adolescents with high SEP and those belonging to upper social classes reported higher levels of risky alcohol consumption.

2008-08-01

The aim of this study was to quantify socioeconomic inequalities in low-back pain, neck-shoulder pain, and arm pain in the general working population in Oslo and to examine the impact of job characteristics on these inequalities. All economically active 30-, 40-, and 45-year-old persons who attended the Oslo health study in 2000-2001 and answered questions on physical job demands, job autonomy, and musculoskeletal pain were included (N=7293). Occupational class was used as an indicator of socioeconomic status. The lower occupational classes were compared with higher grade professionals, and prevalences, prevalence ratios, prevalence differences, and population attributable fractions were calculated. There were marked, stepwise socioeconomic gradients for musculoskeletal pain, steeper for the men than for the women. The relative differences (prevalence ratios) were larger for low-back pain and arm pain than for neck-shoulder pain. The absolute differences (prevalence differences) were the largest for low-back pain. Physical job demands explained a substantial proportion of the absolute occupational class inequalities in low-back pain, while job autonomy was more important in explaining the inequalities in neck-shoulder pain and arm pain. The estimated population attributable fractions supported the impact of job characteristics at the working population level, especially for low-back pain. In this cross-sectional study, physical job demands and job autonomy explained a substantial proportion of occupational class inequalities in self-reported musculoskeletal pain in the working population in Oslo. This finding indicates that the workplace may be an important arena for preventive efforts to reduce socioeconomic inequalities in musculoskeletal pain.

To investigate the prevalence of metabolic syndrome in the Spanish working population and determine how the prevalence varies according to occupation and sex. This was a cross-sectional study of 259,014 workers (mean age 36.4 years, range [16-74]; 72.9% male) who underwent a routine medical checkup. The Adult Treatment Panel III (2001) definition for metabolic syndrome was used. The prevalence of metabolic syndrome was 11.6% (95% CI 11.5-11.7) in male subjects and 4.1% (4.0-4.2) in female subjects and increased with age. The prevalence of metabolic syndrome varied in the different categories of occupational activity depending on the sex considered. Among female subjects, the age-adjusted prevalence of metabolic syndrome was higher in blue-collar than in white-collar workers, but this difference was not evident among male workers. The prevalence of metabolic syndrome varies in the different categories of occupational activity in the Spanish working population. This variation also depends on sex.

Effects of emotion on different phoneme classes

This study investigates the effects of emotion on different phoneme classes using short-term spectral features. In the research on emotion in speech, most studies have focused on prosodic features of speech. In this study, based on the hypothesis that different emotions have varying effects on the properties of the different speech sounds, we investigate the usefulness of phoneme-class level acoustic modeling for automatic emotion classification. Hidden Markov models (HMM) based on short-term spectral features for five broad phonetic classes are used for this purpose using data obtained from recordings of two actresses. Each speaker produces 211 sentences with four different emotions (neutral, sad, angry, happy). Using the speech material we trained and compared the performances of two sets of HMM classifiers: a generic set of ``emotional speech'' HMMs (one for each emotion) and a set of broad phonetic-class based HMMs (vowel, glide, nasal, stop, fricative) for each emotion type considered. Comparison of classification results indicates that different phoneme classes were affected differently by emotional change and that the vowel sounds are the most important indicator of emotions in speech. Detailed results and their implications on the underlying speech articulation will be discussed.

Students' different understandings of class diagrams

Boustedt, Jonas

2012-03-01

The software industry needs well-trained software designers and one important aspect of software design is the ability to model software designs visually and understand what visual models represent. However, previous research indicates that software design is a difficult task to many students. This article reports empirical findings from a phenomenographic investigation on how students understand class diagrams, Unified Modeling Language (UML) symbols, and relations to object-oriented (OO) concepts. The informants were 20 Computer Science students from four different universities in Sweden. The results show qualitatively different ways to understand and describe UML class diagrams and the "diamond symbols" representing aggregation and composition. The purpose of class diagrams was understood in a varied way, from describing it as a documentation to a more advanced view related to communication. The descriptions of class diagrams varied from seeing them as a specification of classes to a more advanced view, where they were described to show hierarchic structures of classes and relations. The diamond symbols were seen as "relations" and a more advanced way was seeing the white and the black diamonds as different symbols for aggregation and composition. As a consequence of the results, it is recommended that UML should be adopted in courses. It is briefly indicated how the phenomenographic results in combination with variation theory can be used by teachers to enhance students' possibilities to reach advanced understanding of phenomena related to UML class diagrams. Moreover, it is recommended that teachers should put more effort in assessing skills in proper usage of the basic symbols and models and students should be provided with opportunities to practise collaborative design, e.g. using whiteboards.

Mind the gap: financial London and the regional class pay gap.

Friedman, Sam; Laurison, Daniel

2017-09-01

The hidden barriers, or 'gender pay gap', preventing women from earning equivalent incomes to men is well documented. Yet recent research has uncovered that, in Britain, there is also a comparable class-origin pay gap in higher professional and managerial occupations. So far this analysis has only been conducted at the national level and it is not known whether there are regional differences within the UK. This paper uses pooled data from the 2014 and 2015 Labour Force Survey (N = 7,534) to stage a more spatially sensitive analysis that examines regional variation in the class pay gap. We find that this 'class ceiling' is not evenly spatially distributed. Instead it is particularly marked in Central London, where those in high-status occupations who are from working-class backgrounds earn, on average, £10,660 less per year than those whose parents were in higher professional and managerial employment. Finally, we inspect the Capital further to reveal that the class pay gap is largest within Central London's banking and finance sector. Challenging policy conceptions of London as the 'engine room' of social mobility, these findings suggest that class disadvantage within high-status occupations is particularly acute in the Capital. The findings also underline the value of investigating regional differences in social mobility, and demonstrate how such analysis can unravel important and previously unrecognized spatial dimensions of class inequality. © London School of Economics and Political Science 2017.

Relative effects of educational level and occupational social class on body concentrations of persistent organic pollutants in a representative sample of the general population of Catalonia, Spain.

Scant evidence is available worldwide on the relative influence of occupational social class and educational level on body concentrations of persistent organic pollutants (POPs) in the general population. The objective was to analyse such influence in a representative sample of the general population of Catalonia, Spain. Participants in the Catalan Health Interview Survey aged 18-74 were interviewed face-to-face, gave blood, and underwent a physical exam. The role of age, body mass index (BMI), and parity was analysed with General Linear Models, and adjusted geometric means (GMs) were obtained. Crude (unadjusted) concentrations were higher in women and men with lower education, and in women, but not men, in the less affluent social class. After adjusting for age, in women there were no associations between POP levels and social class or education. After adjusting for age and BMI, men in the less affluent class had higher p,p'-DDE concentrations than men in class I (p-value=0.016), while men in class IV had lower HCB than men in the upper class (p-value<0.03). Also in contrast with some expectations, positive associations between education and POP levels were observed after adjusting for age and BMI in men; e.g., men with university studies had higher HCB concentrations than men with first stage of primary schooling (adjusted GM 153.9 and 80.5ng/g, respectively) (p-value<0.001). When education and social class were co-adjusted for, some positive associations with education in men remained statistically significant, whereas class remained associated only with p,p'-DDE. Educational level influenced blood concentrations of POPs more than occupational social class, especially in men. In women, POP concentrations were mainly explained by age/birth cohort, parity and BMI. In men, while concentrations were also mainly explained by age/birth cohort and BMI, both social class and education showed positive associations.

2016-01-15

Although suicide rates among Japanese men of working-age have steadily increased over the past two decades, the distribution by occupation and industry is not uniform. Little is known regarding occupation and industry differences in relation to suicide risk. This study examined differences in suicide risk among Japanese men of working age (25-59 years) during 2010. We analysed the Japanese government's 2010 national survey data regarding occupation and industry-specific death rates. Poisson regression models were formulated for each occupation and industry to estimate the relative risk of death by suicide. Potential interactions between age and occupation/industry were also examined. Suicide incidence was highest among workers in the fields of agriculture and mining. When compared with referent groups (sales for occupation and wholesale and retail for industry), the age-adjusted relative risk of suicide was highest for administrative and managerial workers (Incident Relative Risk [IRR]: 3.91, 95% Confidence Interval [95%CI]: 3.16-4.85), service industries (IRR: 3.63, 95%CI: 2.93-4.51) and agriculture (IRR: 3.53, 95%CI: 2.84-4.38) occupations, and for mining (IRR: 23.9, 95%CI: 19.4-29.4), fisheries (IRR: 6.26, 95%CI: 5.03-7.80), electricity and gas (IRR: 5.86, 95%CI: 4.71-7.30) and agricultural industries (IRR: 4.73, 95%CI: 3.78-5.91). Bias resulting from misclassification of deceased individuals' occupation or industry was a potential limitation of this study. Furthermore, detailed information regarding occupation-related factors, such as employment status, had not been recorded in the initial survey. These findings help elucidate Japanese occupations and industries with a higher suicide risk, most likely due to economic changes or workplace factors relating to stress and depression.

Occupational accidents in the Finnish local government sector: utilisation of national statistics.

PubMed

Nenonen, Noora

2011-12-01

Occupational accidents in the Finnish local government sector in 2004 are analysed by gender, age and occupation class in order to identify particular risk groups. The accident data are compared with data concerning the number of employees, using frequency distributions and accident incidence rates. The possibilities of providing occupation class-specific accident incidence rates are also discussed. According to the results, commuting accidents are more common and severe in the local government sector than in general in Finland. In the local public sector occupational accidents more often involved women than men. Compared to other age groups and occupational classes, occupational accidents are more common in the age band of 45-54 and in the occupational class of medical and nursing work. However, compared to the employees' data, men and younger employees had an increased workplace accident risk, while women and older employees had an increased risk of commuting accidents. The highest accident incidence rate was in farming and animal husbandry work. Currently, the calculation of occupation class-specific accident incidence rates is difficult. Improving the consistency of the occupation classifications used in the various data sources would facilitate more reliable calculation of rates.

The association between mother's occupation and cigarette smoking prevalence during pregnancy was analyzed in over 350,000 Washington State births during the years 1984 through 1988. Smoking prevalence during pregnancy varied markedly by maternal age, race, marital status, and social class, with higher smoking rates found in unmarried women, women 25 through 29 years old, native Americans and whites, and women in low socioeconomic classes. Women who worked in traditionally male occupations or in occupations where alcohol was served had the highest smoking rates. Occupational groups with exposure to toxic or carcinogenic substances (including second-hand smoke) also had elevated smoking rates. These data could be useful in planning intervention strategies, in studies of occupational morbidity and mortality, and in analysis of the reproductive effects of maternal occupational exposures.

Socio-economic health inequalities are well documented, but efforts to explain health inequalities are less. However, previous studies suggest that working conditions provide potential explanations for inequalities in health. Cross-sectional questionnaire survey data, collected from municipal employees of the City of Helsinki, aged 40-60 years (n = 8960, response rate 67%) in 2000-02, were examined using binomial regression analysis. Socio-economic position was measured by six occupational social classes ranging from top managers to manual workers, and the outcome was self-rated health (SRH). Key physical and psychosocial working conditions and work arrangements were included as explanatory factors for inequalities in health. Occupational class inequalities in SRH were clear among women [prevalence ratio (PR) 1.89, 95% confidence interval (CI) 1.54-2.32] and men (PR 1.78, 95% CI 1.40-2.25). Heavy physical workload explained a half of the health inequalities among women and almost one-third among men. Physical and chemical exposures at work explained one-fifth of the health inequalities among women and a half among men. Job control explained 24% of the men's and 40% of women's inequalities, whereas job demands widened the inequalities by 13-14%. The effects of shift work and working hours were negligible. In the fully adjusted model, 60% of the women's and 32% of the men's inequalities in SRH were explained. Physical working conditions explained a large part and job control, a somewhat smaller part of socio-economic inequalities in SRH. Improving physical working conditions and increasing job control provide potential routes to reduced inequalities in health among employees.

Cook, W.A.

1989-09-01

The differences in treatment of occupational exposure limits for carcinogens by 24 countries is described along with a discussion of the American Conference of Governmental Industrial Hygienists (ACGIH) threshold limit values (TLV) treatment, the similar treatment of the new Occupational Safety and Health Administration (OSHA) standard, and the treatment by provinces of Canada. The unique listing by the Federal Republic of Germany of so-called technical guiding concentrations of a group of carcinogens is discussed with the note that Austria used this same system. Publications on justification for establishing occupational exposure limits for certain carcinogens are discussed also.

Occupational position, work stress and depressive symptoms: a pathway analysis of longitudinal SHARE data

Hoven, H; Wahrendorf, M; Siegrist, J

2015-01-01

Background Several studies tested whether stressful work mediates the association between socioeconomic position (SEP) and health. Although providing moderate support, evidence is still inconclusive, partly due to a lack of theory-based measures of SEP and work stress, and because of methodological limitations. This contribution aims at overcoming these limitations. Methods We conduct pathway analysis and investigate indirect effects of SEP on mental health via stressful work. Data are derived from the first two waves of the ‘Survey of Health, Ageing and Retirement in Europe’ (SHARE) with information from employed men and women aged 50–64 across 11 European countries (N=2798). SEP is measured according to two alternative measures of occupational position: occupational class (focus on employment relations) and occupational status (focus on prestige). We assess work stress according to the effort-reward imbalance and the demand-control model (wave 1), and we use newly occurring depressive symptoms as health outcome (wave 2). Results Effort-reward imbalance and, less consistently, low control mediate the effect of occupational class and occupational status on depressive symptoms. Conclusions Our findings point to two important aspects of work stress (effort-reward imbalance and low control) in explaining socioeconomic differences in health. Further, we illustrate the significance of two alternative dimensions of occupational position, occupational class and occupational status. PMID:25648992

Occupational accidents in professional dance with focus on gender differences

PubMed Central

2013-01-01

Background Classical dance comprises gender specific movement tasks. There is a lack of studies which investigate work related traumatic injuries in terms of gender specific differences in detail. Objective To define gender related differences of occupational accidents. Methods Basis for the evaluation were occupational injuries of professional dancers from three (n = 785; f: n = 358, m: n = 427) state theatres. Results The incidence rate (0.36 per year) was higher in males (m: 0.45, f: 0.29). There were gender specific differences as to the localizations of injuries, particularly the spine region (m: 17.3%, f: 9.8%, p = 0.05) and ankle joint (m: 23.7%, f: 35.5%, p = 0.003). Compared to male dancers, females sustained more injuries resulting from extrinsic factors. Significant differences could specifically be observed with dance floors (m: 8.8%, f: 15.1%, p = 0.02). There were also significant gender differences observed with movement vocabulary. Conclusion The clearly defined gender specific movement activities in classical dance are reflected in occupational accidents sustained. Organisational structures as well as work environment represent a burden likewise to male and female dancers. The presented differences support the development of gender specific injury prevention measures. PMID:24341391

The aim of this study was to evaluate gender differences in the respiratory health of workers exposed to organic and inorganic dusts. Meta-analysis techniques incorporating logistic regression were applied to a combined file of 12 occupational health studies. Meta-analysis of data on 1,367 women and 4,240 men showed that women had higher odds of shortness of breath whether exposed to inorganic dust or having no occupational exposure, with an overall odds ratio (OR) of 2.07 (95% confidence interval [CI] = 1.57-2.73) adjusted for smoking status, age, body mass index (BMI), ethnic status, atopy, and job duration. Inorganic dust exposure was associated with the highest odds of asthma (adjusted OR = 8.38, 95% CI = 1.72-40.89) for women compared to men, but no differences were found for unexposed workers. With organic dust exposure, men had elevated odds for occasional wheeze and worse lung function compared to women. Within the limitations of this analysis, gender differences in respiratory health, as suggested by population-based studies, were confirmed in our analysis of occupational health studies, with the general type of exposure, organic or inorganic, generally determining the extent of differences. The higher risks for women compared to men for shortness of breath were robust regardless of work exposure category, with the highest odds ratios found for asthma.

This study was conducted to assess occupational stress in different gender, age, work duration, educational level and marital status group. A test of occupational stress in different gender, age, work duration, educational level and marital status group, was carried out with revised occupational stress inventory (OSI-R) for 4278 participants. The results of gender show that there are heavier occupational role, stronger interpersonal and physical strain in male than that in female, and the differences are statistically significant (P < 0.01). The score of recreation in the male is higher than that in female, but the score of self-care in the female is higher than that in male, and the differences are statistically significant (P < 0.01). Difference in the scores of occupational role, personal resource among various age groups is significant (P < 0.01). Vocational, interpersonal strain scores among various age groups is significant (P < 0.05). The results of educational level analyses suggest that the difference in the scores of occupational stress and strain among various educational levels show statistically significant (P < 0.05), whereas there are no statistic significance of coping resources among the groups (P > 0.05).

Objective We sought to determine whether demographic differences in eye injury rates persist after adjusting for occupational exposure. Methods On-duty eye injury hospitalizations were linked to occupation among active-duty US Army personnel. Results Eye injury rates were higher for white solidiers, men, and for younger soldiers, even after adjusting for occupational group and specific job titles using multivariate models. Conclusions This finding contrasts with studies of other injuries, suggesting that occupation does not fully account for variations in eye injury risk. Because protective eyewear can prevent most serious eye injuries, we hypothesize that differences in protective eyewear use between men and women may contribute to differences in eye injury rates, although follow-up studies are needed to confirm this. Prevention efforts should consider targeting high-risk demographic groups in addition to high-risk occupations. PMID:15951724

To analyze the status of occupational stress in different types of train drivers. By using cluster sampling method, a cross-sectional study was conducted in 1 339 train drivers (including 289 passenger train drivers, 637 freight trains drivers, 339 passenger shunting train drivers, and 74 high speed rail drivers) from a Railway Bureau depot. The survey included individual factors, occupational stress factors, stress response factors and stress mitigating factors. The occupational stress factors, stress response factors and mitigating factors were measured by the revised effort-reward imbalance (ERI) model questionnaires and occupational stress measurement scale. By using the method of covariance analysized the difference of occupational stress factors of all types train drivers, the method of Stepwise regression was used to analyze the effection (R(2)) of occupational stress factors and stress mitigating factors on stress response factors. Covariance analysis as covariates in age, education level, length of service and marital status showed that the scores of ERI (1.58 ± 0.05), extrinsic effort (19.88 ± 0.44), rewards (23.43 ± 0.43), intrinsic effort (17.86 ± 0.36), physical environment (5.70 ± 0.22), social support (30.51 ± 0.88) and daily tension (10.27 ± 0.38 ) of high speed rail drivers were higher than other drivers (F values were 6.06, 11.32, 7.05, 13.25, 5.20, 9.48 and 6.14 respectively, P < 0.01), but the scores of emotional balance (4.15 ± 0.31) and positive emotion (2.06 ± 0.20) were lower than other drives (P < 0.01);the scores of psychological needs (10.48 ± 0.18), emotional balance (4.88 ± 0.16) and positive emotion (2.63 ± 0.10) of passenger train drivers were higher than other drivers (F values were 4.33 and 5.50 respectively, P < 0.01). The descending rank of the effect value on occupational stress factors and mitigating factors to depressive symptoms of train drivers was high speed rail drivers (R(2) = 0.64), passenger train drivers (R

To study the effect of occupational stress on cardiovascular function of different vocational population. The occupational stressors, risk factors of cardiovascular diseases were investigated by questionnaire in 839 people with 4 kinds of jobs. Blood pressure, sugar, and lipid were detected at the same time. Blood pressure were higher in the groups of old age, long standing and teachers, and the abnormal rate of blood pressure was 21.69%. There was no difference in abnormal ECG among ages, standing and occupation, and the abnormal rate of ECG was 19.07%. Job control, job demands, job responsibility, role in a job and shift work were the main stress factors affecting systolic and diastolic blood pressure. More conflict in job, less chance of participation, severe job loads were the risk factors of primary hypertension. Accident due to job responsibility, job responsibility, role in a job were the main risk factors of abnormal electrocardiograph. Self-respect and activity beyond work were the good modifiers of heart function. Occupational stress has certain effect on cardiovascular function.

Gender differences in respiratory symptoms-does occupation matter?

Little attention has been given to gender differences in respiratory health, particularly in occupational settings. The purpose of this paper was to evaluate gender differences in respiratory morbidity based on surveys of hospitality workers, radiographers, and respiratory therapists. Data were available from mail surveys of 850 hospitality industry workers (participation rate 73.9%; 52.6% female), 586 radiographers (participation rate 63.6%; 85% female), and 275 respiratory therapists (participation rate 64.1%; 58.6% female). Cross-tabulations by gender were evaluated by chi(2) analysis and logistic regression with adjustment for personal and work characteristics. Women consistently had greater respiratory morbidity for symptoms associated with shortness of breath, whereas men usually had a higher prevalence of phlegm. There were few differences in work exposures apart from perception of exposure to ETS among hospitality workers. Gender differences in symptoms were often reduced after adjustment for personal and work characteristics but for respiratory therapists there were even greater gender disparities for asthma attack and breathing trouble. Population health findings of elevated symptoms among women were only partially supported by these occupational respiratory health surveys. The influence of differential exposures and personal factors should be considered when interpreting gender differences in health outcomes.

To describe differences in four high risk periconceptional behaviors (lack of folic acid supplementation, lack of early prenatal care, smoking, and drinking) by maternal occupation. Analyses were conducted among women in the National Birth Defects Prevention Study who delivered liveborn infants without birth defects. Periconceptional occupational data were collected using a computer-assisted telephone interview and occupational coding was performed using the 2000 Standard Occupational Classification System. Logistic regression analyses were conducted to determine whether prevalence of behaviors differed between occupational groups. Subjects included 5153 women employed during early pregnancy from 1997 to 2007. Compared to women in management, business, science, and arts occupations, women in other occupations (e.g., service occupations) were significantly more likely to engage in all four high risk behaviors. Specifically, women in food preparation/serving-related occupations were significantly more likely to engage in all four behaviors compared to women in all other occupational groups (odds ratios: 1.8-3.0), while women in education/training/library occupations were significantly less likely to do so (odds ratios: 0.2-0.5). We identified several occupational groups with an increased prevalence of high-risk maternal behaviors during pregnancy. Our findings could aid in developing interventions targeted towards women in these occupational groups. Copyright © 2012 Elsevier Inc. All rights reserved.

UNEQUAL RISK: COMBAT OCCUPATIONS IN THE VOLUNTEER MILITARY

2011-01-01

This study evaluates the characteristics of the men who served in the volunteer military in combat occupations. It examines whether these characteristics stem from supply-side or demand-side decisions, or reflect class bias. The findings suggest that, on the supply side, men who had greater academic abilities were more likely to go to college, thereby avoiding military service and the possibility of serving in a combat occupation. On the demand side, the armed forces were more likely to exclude men with lower academic abilities but were more likely to assign such men in the military to combat occupations. Net of the impacts of these supply-side and demand-side decisions, men who served in combat occupations still differed from those who did not in terms of their family background. The impact of family background was stronger on entering the military than on being assigned to combat occupations once in the military. PMID:21691446

We examined whether occupational and household tasks contributed to differences in pain between African Americans and whites with radiographic knee osteoarthritis (OA). Participants from the Johnston County Osteoarthritis Project self-reported the frequency (often/always vs never/seldom/sometimes) of performing 9 occupational tasks involving lower extremity joint loading at their longest job (N = 868) and current job (N = 273), as well as 8 household tasks ever performed (N = 811) and currently being performed (N = 767). The associations of the numbers of occupational or household tasks with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale were first examined in simple linear regression models. If significantly associated with greater pain, each of these was included in adjusted linear regression models to examine whether the association of race with pain remained statistically significant. African Americans reported significantly greater WOMAC pain scores than whites. Exposures to more occupational tasks at the longest job and the current job were associated with greater WOMAC pain scores (p < 0.01). The association of race with greater pain scores remained statistically significant when controlling for occupational tasks at the longest job, but was reduced by 26% and no longer significant when controlling for the number of current occupational tasks. Exposures to an increasing number of household tasks were associated with lower pain scores and were not further analyzed. Current performance of physically demanding occupational tasks contributed to racial differences in pain severity among individuals with knee OA. Better workplace policies to accommodate OA-related limitations may help to reduce racial differences in pain.

Rising Intragenerational Occupational Mobility in the United States, 1969 to 2011

PubMed Central

Jarvis, Benjamin F.; Song, Xi

2017-01-01

Despite the theoretical importance of intragenerational mobility and its connection to intergenerational mobility, no study since the 1970s has documented trends in intragenerational occupational mobility. The present article fills this intellectual gap by presenting evidence of an increasing trend in intragenerational mobility in the United States from 1969 to 2011. We decompose the trend using a nested occupational classification scheme that distinguishes between disaggregated micro-classes and progressively more aggregated meso-classes, macro-classes, and manual and nonmanual sectors. Log-linear analysis reveals that mobility increased across the occupational structure at nearly all levels of aggregation, especially after the early 1990s. Controlling for structural changes in occupational distributions modifies, but does not substantially alter, these findings. Trends are qualitatively similar for men and women. We connect increasing mobility to other macro-economic trends dating back to the 1970s, including changing labor force composition, technologies, employment relations, and industrial structures. We reassert the sociological significance of intragenerational mobility and discuss how increasing variability in occupational transitions within careers may counteract or mask trends in intergenerational mobility, across occupations and across more broadly construed social classes.

Prevalence of excess weight varies substantially by socioeconomic position (SEP). SEP can be defined with different indicators. The strength of the association of SEP with excess weight differs by SEP indicator, between populations and over time. We examined the prevalence of overweight and obesity (body mass index 25-29.9 and ≥30 kg m(-2) ) in Switzerland by educational level, household income tertile and occupational class (three categories for each indicator). Self-reported data stem from four cross-sectional population surveys including 53 588 persons aged between 25 and 74 years. The overall prevalence of overweight increased between 1992 and 2007 from 37.4% to 41.4% in men and from 18.8% to 21.9% in women. Obesity prevalence increased from 7.2% to 9.7% in men and from 5.4% to 8.6% in women. Inequalities were calculated with multivariable logistic regression. Inequalities were larger in women than in men and for obesity than for overweight. However, overweight and obesity inequalities did not significantly change over time, despite overall increasing prevalence. Although all SEP indicators were independently associated with excess weight, the association was strongest with education, particularly in women. Programmes and policies aimed at preventing excess weight should target individuals with low education early in life. © 2010 The Authors. obesity reviews © 2010 International Association for the Study of Obesity.

Explaining turnover intention in Korean public community hospitals: occupational differences.

Hwang, Jee-In; Chang, Hyejung

2008-01-01

Personnel in public hospitals had relatively low job satisfaction despite of tenure employment. High turnover rates degrade hospital image and incur additional costs related to recruitment and training. The purposes of this study were to describe the occupational differences and to identify factors affecting turnover intention among public hospital personnel. A questionnaire survey was conducted as part of Administrative Services Quality Evaluation Program by Seoul metropolitan municipality from 1 November to 1 December in 2003. The subjects were 1251 entire hospital personnel in four hospitals. The questionnaire was designed to measure job satisfaction, organizational commitment, turnover intention, and demographic characteristics. Logistic regression analysis was performed to determine factors influencing turnover intention. There were significant differences in job satisfaction, organizational commitment, and turnover intention according to the occupations. The turnover intention rates were highest among physicians, followed by paramedicals and nursing staffs and then administrators. The significant factors affecting turnover intention were involvement and loyalty among physicians, hospital type, satisfaction with systems and loyalty among nursing staffs, satisfaction with relationship and loyalty among administrators, and loyalty among paramedicals. There were different moderators that influence turnover intentions of hospital personnel. Loyalty had the most important effect upon turnover intention in all occupations. 2007 John Wiley & Sons, Ltd

Active site nanospace of aminoacyl tRNA synthetase: difference between the class I and class II synthetases.

PubMed

Dutta, Saheb; Choudhury, Kaberi; Banik, Sindrila Dutta; Nandi, Nilashis

2014-03-01

The present work is aimed at understanding the origin of the difference in the molecular organization of the active site nanospaces of the class I and class II aminoacyl tRNA synthetases (aaRSs) which are tunnel-like structures. The active site encloses the cognate amino acid (AA) and the adenosine triphosphate (ATP) to carry out aminoacylation reaction. Comparison of the structures of the active site of the class I and class II (aaRSs) shows that the nanodimensional tunnels are curved in opposite directions in the two classes. We investigated the origin of this difference using quantum mechanical computation of electrostatic potential (ESP) of substrates, surrounding residues and ions, using Atoms in Molecule (AIM) Theory and charge population analysis. We show that the difference is principally due to the variation in the spatial charge distribution of ATP in the two classes which correspond to extended and bent conformations of ATP. The present computation shows that the most feasible pathway for nucleophilic attack to alphaP is oppositely directed for class I and class II aaRSs. The available crystal structures show that the cognate AA is indeed located along the channel favorable for nucleophilic attack as predicted by the ESP analysis. It is also shown that the direction of the channel changes its orientation when the orientation of ATP is changed from extended to a bent like structure. We further used the AIM theory to confirm the direction of the approach of AA in each case and the results corroborate the results from the ESP analysis. The opposite curvatures of the active site nanospaces in class I and class II aaRSs are related with the influence of the charge distributions of the extended and bent conformations of ATP, respectively. The results of the computation of electrostatic potential by successive addition of active site residues show that their roles on the reaction are similar in both classes despite the difference in the organization of the

Number of sick leave days vary by county, but little is known about the extent to which this gradient may be explained by differences pertaining to occupational composition and occupational exposure. A randomly drawn cohort from the general population in Norway, aged 18-69 years, was interviewed by telephone in the second half of 2009 ( n=12,255; response at baseline=60.9%) and followed up in national registries to the end of 2010. Eligible respondents were registered with an active employee relationship in 2009 and 2010 ( n=8275). Information on counties ( n=19) was based on the administrative register. The outcome of interest was the number of physician-certified sick-leave days divided by scheduled man-days during 2010 (i.e. sick-leave percentage (SLP)). The average SLP during 2010 was 5.2%. The between-county variation in SLP ranged from 4.0% to 7.2%. Compared to the age- and gender-adjusted model, adjustment for occupation, economic sector and self-reported occupational exposure reduced the median difference in SLP between the county with the lowest SLP (reference county) and the SLP in the other counties by 1.08 percentage points (i.e. a 58% reduction). The impact of occupational composition and occupational exposure on the total between-county variance in SLP was a 16% reduction. Occupational composition and self-reported occupational exposure help to explain a significant part of the difference in SLP between counties, and appear to be more important explanatory factors than demographic variables, self-reported health and smoking.

Paternal occupational exposures have been proposed as a risk factor for childhood leukaemia. This study investigates possible associations between paternal occupational exposure and childhood leukaemia in Great Britain. The National Registry of Childhood Tumours provided all cases of childhood leukaemia born and diagnosed in Great Britain between 1962 and 2006. Controls were matched on sex, period of birth and birth registration subdistrict. Fathers' occupations were assigned to 1 or more of 33 exposure groups. Social class was derived from father's occupation at the time of the child's birth. A total of 16 764 cases of childhood leukaemia were ascertained. One exposure group, paternal social contact, was associated with total childhood leukaemia (odds ratio 1.14, 1.05-1.23); this association remained significant when adjusted for social class. The subtypes lymphoid leukaemia (LL) and acute myeloid leukaemia showed increased risk with paternal exposure to social contact before adjustment for social class. Risk of other leukaemias was significantly increased by exposure to electromagnetic fields, persisting after adjustment for social class. For total leukaemia, the risks for exposure to lead and exhaust fumes were significantly <1. Occupationally derived social class was associated with risk of LL, with the risk being increased in the higher social classes. Our results showed some support for a positive association between childhood leukaemia risk and paternal occupation involving social contact. Additionally, LL risk increased with higher paternal occupational social class.

Class categories and the subjective dimension of class: the case of Denmark.

Class relations have been proven to affect various aspects of social life, even in modern individualized societies. However, following claims on individualization and the so-called 'death of class' thesis, studying the subjective dimension of class - that is, the way individuals perceive of class relations and their own position within them - has gone out of style. We argue that even in equalized societies, subjective class perceptions may still influence attitudes and behaviour as they evolve to fit modern class relations. To explore the existence as well as structure and content of perceived social classes, this article investigates how people describe society and social groups in focus group discussions. We find that groups in different positions in terms of education and economy all tend to apply hierarchical class categories to describe Danish society, which is normally seen as one of the most equal societies and political systems in the world. In addition, we find that economic resources serve as a baseline for the hierarchical ordering, often supplemented with notions of education, lifestyle and/or occupational profile. Even though people are somewhat uncomfortable with the notion of class, their descriptions of Danish society and classes are surprisingly similar within and across groups. We conclude that not only do class relations matter; people are also highly aware of the existing classes and able to position themselves and others according to their notion of classes. © London School of Economics and Political Science 2017.

Site occupancy models with heterogeneous detection probabilities

Royle, J. Andrew

2006-01-01

Models for estimating the probability of occurrence of a species in the presence of imperfect detection are important in many ecological disciplines. In these ?site occupancy? models, the possibility of heterogeneity in detection probabilities among sites must be considered because variation in abundance (and other factors) among sampled sites induces variation in detection probability (p). In this article, I develop occurrence probability models that allow for heterogeneous detection probabilities by considering several common classes of mixture distributions for p. For any mixing distribution, the likelihood has the general form of a zero-inflated binomial mixture for which inference based upon integrated likelihood is straightforward. A recent paper by Link (2003, Biometrics 59, 1123?1130) demonstrates that in closed population models used for estimating population size, different classes of mixture distributions are indistinguishable from data, yet can produce very different inferences about population size. I demonstrate that this problem can also arise in models for estimating site occupancy in the presence of heterogeneous detection probabilities. The implications of this are discussed in the context of an application to avian survey data and the development of animal monitoring programs.

Studies examining workers' diet according to smaller occupational groups within "large occupational categories" are sparse. The aim of this study was to examine the potential differences in workers' diets based on the classification of workers into smaller occupational groups that comprise "large occupational categories". The subjects of this study were working fathers who had participated in the Japan Environment and Children's Study (N = 38,656). Energy and nutrient intake were calculated based on data collected from the Food Frequency Questionnaire. Occupations were classified according to the Japanese Standard Occupational Classification. Logistic regression analyses were performed to examine the adherence to current dietary recommendations within smaller occupational groups. In particular, significant differences were observed among the categorical groups of "professional and engineering workers", "service workers", and "agricultural, forestry, and fishery workers". In "professional and engineering workers", teachers showed higher odds of adherence to calcium intake recommendations compared with nurses (OR, 2.54; 95% CI, 2.02⁻3.14; p < 0.001). In "agricultural, forestry, and fishery workers", agriculture workers showed higher odds of adherence to calcium (OR, 2.15; 95% CI, 1.46⁻3.15; p < 0.001) and vitamin C (OR 1.90, 95% CI 1.31⁻2.74, p = 0.001) intake recommendations compared with forestry and fishery workers. These findings may be beneficial from a research perspective as well as in the development of more effective techniques to improve workers' diet and health.

Occupation, well-being, and culture: Theory and cultural humility.

PubMed

Hammell, Karen R Whalley

2013-10-01

The Canadian Model of Occupational Performance and Engagement depicts individuals embedded within cultural environments that afford occupational possibilities. Culture pertains not solely to ethnicity or race but to any dimension of diversity, including class, gender, sexual orientation, and ability. This paper highlights specific dimensions of cultural diversity and their relationships to occupational engagement and well-being. Cultural variations constitute the basis for a socially constructed hierarchy of traits that significantly determine occupational opportunities and impact mental health and well-being. Cultural humility is an approach to redressing power imbalances in client-therapist relationships by incorporating critical self-evaluation and recognizing that cultural differences lie not within clients but within client-therapist relationships. It is proposed that theoretical relevance would be enhanced if culturally diverse perspectives were incorporated into theories of occupation. Cultural humility is advocated as an approach to theoretical development and in efforts to counter professional Eurocentrism, ethnocentrism, and intellectual colonialism.

Model selection and assessment for multi­-species occupancy models

Broms, Kristin M.; Hooten, Mevin B.; Fitzpatrick, Ryan M.

While multi-species occupancy models (MSOMs) are emerging as a popular method for analyzing biodiversity data, formal checking and validation approaches for this class of models have lagged behind. Concurrent with the rise in application of MSOMs among ecologists, a quiet regime shift is occurring in Bayesian statistics where predictive model comparison approaches are experiencing a resurgence. Unlike single-species occupancy models that use integrated likelihoods, MSOMs are usually couched in a Bayesian framework and contain multiple levels. Standard model checking and selection methods are often unreliable in this setting and there is only limited guidance in the ecological literature for this class of models. We examined several different contemporary Bayesian hierarchical approaches for checking and validating MSOMs and applied these methods to a freshwater aquatic study system in Colorado, USA, to better understand the diversity and distributions of plains fishes. Our findings indicated distinct differences among model selection approaches, with cross-validation techniques performing the best in terms of prediction.

To investigate the human papillomavirus (HPV) infection and cervical intraepithelial neoplasia (CIN) morbidity of women from different occupations in Shenzhen city. 2045 women of five kinds of occupation in Shenzhen city, including 130 teachers, 385 workers, 316 service women, 199 poverish women, 420 doctors or nurses and 595 general residents were included. We screened these women by methods of detecting high risk HPV of hc2 combing with LCT. Women with screening positive results were diagnosed CIN by colposcopic biopsy. (1) High risk factors on HPV infection rate in different occupations were different with the highest in service occupation (19.3%) while the lowest appeared in medical workers (11.9%). (2) In those 2045 women, we found 199 cervical lesions including pathological HPV infection, CIN1, 2, 3 and cervical cancers, with morbidity rates as 4.11%, 3.28%, 1.67%, 0.54% and 0.15% respectively. Along with the progress of the cervical lesions, the morbidity decreased. (3) The morbidity rates of CIN in different occupations were different, with the highest of HSIL in service occupation and the lowest in teachers. Women of different occupations in Shenzhen city had different high risk HPV infection rates and CIN morbidity. The HPV infection rate and HSIL morbidity were highest among women having service related jobs.

Background: Paternal occupational exposures have been proposed as a risk factor for childhood leukaemia. This study investigates possible associations between paternal occupational exposure and childhood leukaemia in Great Britain. Methods: The National Registry of Childhood Tumours provided all cases of childhood leukaemia born and diagnosed in Great Britain between 1962 and 2006. Controls were matched on sex, period of birth and birth registration subdistrict. Fathers' occupations were assigned to 1 or more of 33 exposure groups. Social class was derived from father's occupation at the time of the child's birth. Results: A total of 16 764 cases of childhood leukaemia were ascertained. One exposure group, paternal social contact, was associated with total childhood leukaemia (odds ratio 1.14, 1.05–1.23); this association remained significant when adjusted for social class. The subtypes lymphoid leukaemia (LL) and acute myeloid leukaemia showed increased risk with paternal exposure to social contact before adjustment for social class. Risk of other leukaemias was significantly increased by exposure to electromagnetic fields, persisting after adjustment for social class. For total leukaemia, the risks for exposure to lead and exhaust fumes were significantly <1. Occupationally derived social class was associated with risk of LL, with the risk being increased in the higher social classes. Conclusion: Our results showed some support for a positive association between childhood leukaemia risk and paternal occupation involving social contact. Additionally, LL risk increased with higher paternal occupational social class. PMID:22968649

Differences in competitive ability for the occupancy of shelters in triatomines.

PubMed

Zacharias, C A; Minoli, S A; Manrique, G

2017-09-01

Triatomines (Hemiptera: Reduviidae: Triatominae) are nocturnal blood-sucking insects. During daylight hours they remain in an akinetic state inside their shelters, whereas at dusk they become active and move outside. When they are outside their shelters during the photophase, triatomines are vulnerable to diurnal predators and the period just before dawn is critical to their survival. This work analyses the existence of competitive interactions involved in the occupancy of shelters by triatomines. Behavioural assays were performed in which nymphs of different stages, nutritional status or species were released in an experimental arena containing a space-limited artificial shelter. The proportions of individuals occupying the shelter during the photophase were quantified to estimate the competitive abilities of each stage and species. Intraspecific comparisons showed higher levels of shelter occupancy for fourth over fifth instars and fed over unfed nymphs of Triatoma infestans. Interspecific comparisons showed higher rates of shelter occupancy for Triatoma sordida in comparison with T. infestans, and for T. infestans over Rhodnius prolixus. Arrival order was also relevant to determining shelter occupancy levels: early arrival was advantageous in comparison with later arrival. The study of intra- and interspecific competitive interactions for shelter occupancy provides relevant information about colonization and recolonization processes in the natural environments of triatomines. © 2017 The Royal Entomological Society.

Occupational social class and mortality in a population of men economically active: the contribution of education and employment situation.

2005-01-01

This study examines how education and employment situation contribute to the association between a classification of occupational class based on skill assets and mortality from different causes of death. Data were obtained by linking records from the 1996 population census for Spanish men aged 35-64 residing in Madrid with 1996 and 1997 mortality records. The risk of mortality was higher in skilled, semi-skilled and unskilled workers than in higher and lower managerial and professional workers. Adjusting for educational level substantially decreased the magnitude of the gradient. The decrease in the gradient after adjusting for employment situation was much smaller. Except in the case of mortality from respiratory diseases, the mortality gradient disappeared after adjusting for both variables. These results show that education and, to a much lesser degree, employment situation explain part of the social gradient observed in mortality from all causes and from broad causes of death, except from respiratory diseases.

Civilian suicide rates vary by occupation in ways related to occupational stress exposure. Comparable military research finds suicide rates elevated in combat arms occupations. However, no research has evaluated variation in this pattern by deployment history, the indicator of occupation stress widely considered responsible for the recent rise in the military suicide rate. The joint associations of Army occupation and deployment history in predicting suicides were analysed in an administrative dataset for the 729 337 male enlisted Regular Army soldiers in the US Army between 2004 and 2009. There were 496 suicides over the study period (22.4/100 000 person-years). Only two occupational categories, both in combat arms, had significantly elevated suicide rates: infantrymen (37.2/100 000 person-years) and combat engineers (38.2/100 000 person-years). However, the suicide rates in these two categories were significantly lower when currently deployed (30.6/100 000 person-years) than never deployed or previously deployed (41.2-39.1/100 000 person-years), whereas the suicide rate of other soldiers was significantly higher when currently deployed and previously deployed (20.2-22.4/100 000 person-years) than never deployed (14.5/100 000 person-years), resulting in the adjusted suicide rate of infantrymen and combat engineers being most elevated when never deployed [odds ratio (OR) 2.9, 95% confidence interval (CI) 2.1-4.1], less so when previously deployed (OR 1.6, 95% CI 1.1-2.1), and not at all when currently deployed (OR 1.2, 95% CI 0.8-1.8). Adjustment for a differential 'healthy warrior effect' cannot explain this variation in the relative suicide rates of never-deployed infantrymen and combat engineers by deployment status. Efforts are needed to elucidate the causal mechanisms underlying this interaction to guide preventive interventions for soldiers at high suicide risk.

Survey data from 215 nurses (10 male) and 430 civil engineers (10 female) supported the plausibility of occupation-specific models (positing direct paths between role stressors, antecedents, and consequences) compared to generic models. A weakness of generic models is the tendency to ignore differences in occupational structure and culture. (SK)

Bladder cancer (BC) is a common disease. Despite manufacturing and legislative changes to workplace hygiene, many BCs still arise through occupational carcinogen exposure. To profile contemporary risks of occupational BC. A systematic review using PubMed, Medline, Embase, and Web of Science was performed in October 2012 (initial review) and May 2014 (final review) and was updated in June 2015. We identified 263 eligible articles. We excluded reports in which BC or occupation were not the main focus, and those with insufficient case, risk, or confidence interval data. We selected the most recent data from populations with multiple reports. Reports were selected by 2 of us independently. We combined odds ratios and risk ratios (RRs) to provide pooled RRs, using maximally adjusted RRs in a random effects model. Heterogeneity and publication bias were assessed using I2 and Begg and Egger tests. Risk estimates were annotated by occupational class using Nordisk Yrkesklassificering, or Nordic Occupational Classification, and International Standard Classifications of Occupations (NYK and ISCO-1958) Codes. Occupations were profiled by BC incidence and mortality risk over time. After data collection, we detected a sex difference in these profiles and recorded this as a secondary outcome. Meta-analysis revealed increased BC incidence in 42 of 61 occupational classes and increased BC-specific mortality in 16 of 40 occupational classes. Reduced incidence and mortality were seen in 6 of 61 and 2 of 40 classes, respectively. Risk varied with sex and was greatest in men (standardized incidence ratio, 1.03 [95% CI, 1.02-1.03]; P < .001]). From the 1960s to the 1980s, there was a steady decline in standarized incidence ratio (SIR) for both sexes. This trend reversed from the 1980s, as in the decade 2000 to 2010 the SIR increased to 1.13 (95% CI, 1.07-1.19) for men and 1.27 (95% CI, 1.12-1.43) for women. In contrast, mortality risk declined for both sexes from the 1960s to the 1990s

The politics of reproductive hazards in the workplace: class, gender, and the history of occupational lead exposure.

PubMed

Morello-Frosch, R A

1997-01-01

Over the past two decades, several U.S. companies have sought to bar women from jobs that expose them to potential reproductive hazards, justifying these exclusionary policies by their professed concerns for the well-being of unborn children and potential liability. Although recent court cases have stimulated academic interest in this issue, a historical review of the public health and medical literature reveals that this debate is not new. To understand the logic behind the emergence of "fetal protection" policies, one must examine the scientific history of occupational teratogens and the socio-political and economic forces that have driven scientific research in this field. Using lead as an example, the author argues that research on the reproductive hazards of employment has historically emphasized the risks to women and downplayed the risks to men. This results in environmental health policies that do not uphold the ultimate goal of occupational safety for all workers, but rather reinforce the systemic segregation of men and women in the workplace. Although the political struggle over exclusionary policies has a feminist orientation, it also has important class dimensions and ultimately must be viewed within the broader context of American capitalist production.

Examine the differences in weekly high-risk alcohol consumption among working people by economic sector and occupation. Secondary analysis of data from Cycle 2.1 of the Canadian Community Health Survey conducted by Statistics Canada. The sample comprised 76,136 subjects 15 years of age and older in 139 occupations and 96 economic sectors. The prevalence of weekly high-risk alcohol consumption is estimated to be 8% among workers. Major disparities exist between men (11%) and women (6%). The results suggest a differential in weekly high-risk alcohol consumption by occupation and economic sector that is independent of working conditions, family status, and personal characteristics. Workers in five occupational groups have a greater likelihood of at-risk consumption (OR 1.88-2.94), whereas seven economic sectors stand out as having a lower risk (OR 0.25-0.59). Occupation appears to be of greater utility than economic sector for defining courses of action in public health. These research results make it possible to identify a set of occupations to target for preventive interventions in conjunction with other public health interventions.

The effect of occupational and workplace gender composition on sickness absence.

2012-02-01

To examine whether gender composition of the occupation or the workplace is associated with sickness absence, whether the gender composition accounts for the observed female excess in sickness absence, and whether gender composition explains variation in sickness absence rates between occupations and workplaces. Random effects models conducted among Helsinki employees (N = 36,395). Women and men working in women-dominated occupations and workplaces had more short-term (1 to 3 days') sickness absence. Gender composition of the occupation and the workplace partly explained gender differences in short-term but not in intermediate (4 to 14 days') and long-term (>2 weeks') absence. Gender composition also explained variation in short-term sickness absence among occupations and workplaces, but this was partly accounted for by social class, income, and job contract type. The results are consistent with the assumption that short-term sickness absence reflects cultures and norms shaping sickness absence behavior.

Mother's social class and perinatal problems in a low-problem area.

1990-12-01

This study reports the variation in perinatal problems related to social class in one area in Finland. Data on length of gestation, birthweight, one-minute Apgar score, and need for special care in relation to social class were obtained from a large clinical trial (n = 2912) on iron prophylaxis during pregnancy. Social class was determined from the woman's own occupation and education. Occupation was obtained from the women themselves and classified as upper white collar, lower white collar I, lower white collar II, and workers; entrepreneurs, students and women with no information were excluded. Education was obtained by record linkage to the national education register, and all women were classified by the years normally required to attain a certain level: greater than or equal to 13, 12, 10-11, and less than or equal to 9 years of education. Adjusted for age and parity, a week U-shaped curve was found for gestation length and birthweight, best results being found for the women in the second highest social class. The lower the social class, the more infants with poor Apgar scores. As potential intervening variables we studied marital status, pre-pregnancy weight, smoking, and haematocrit in the 28th week of pregnancy. Their inclusion in multivariate analyses influenced only slightly the differences in perinatal problems between the groups. Our results suggest that in Finland there are still differences in perinatal problems between social classes, but that the relationship is not always linear.

2008-01-01

Earlier studies and statistics have shown that merchant seafarers from the South East Asia had considerable lower accident rates when compared with seafarers from Western Europe. The purposes of the study were to investigate whether the earlier observations were sustained if further sources on occurrence of accidents were used and to identify specific causes of excess accident rates among certain nationalities. Occupational accidents aboard Danish merchant ships during one year were identified from four different sources. These included accidents reported to the maritime authorities, accidents reported to a mutual insurance company, files on medical costs reimbursed by the government and finally, accidents in which there has been contact to the radio medical service. Time at risk aboard was obtained from a register on all employment periods aboard merchant ships. A total of 943 accidents causing personal injury to a seafarer directly caused by work aboard were identified. Among these accidents, 499 had taken place aboard cargo ships in international trade. Only these were used in the detailed analysis. The accident rate for all identified accidents aboard cargo ships were 84 accidents per 1,000 years aboard. The crude incidence rate ratio (IRR) for East European seafarers was 0.88 and for South East Asians 0.38 using West European seafarers as reference. In a Poisson regression analysis, the IRR for South East Asians was 0.29 (0.22-0.38). In an analysis including only more serious accidents, IRR for South East Asians rose to 0.36 (0.26-0.48). This study indicates that seafarers from South East Asia, mainly the Philippines, may have a genuine lower risk of occupational accidents in comparison with seafarers from Western and Eastern Europe. Differences in approach to safety and risk taking between South East Asian and European seafarers should be identified and positives attitudes included in accident preventing programmes.

Within the multi-functionality of educational buildings, the energy conservation potential can be very different. In addition, among different retrofitting solutions investigated involving interventions on the building envelope, ventilation strategies, artificial lighting systems as well as equipment upgrading, different saving potential would come from different aspects. The opportunities for energy saving potential from the overall point of view and from the detailed aspect view of different retrofitting solutions would be very useful and important for building renovation decision making. This study presents a detailed retrofitting study of two different educational buildings. One represents a building with average occupancy variation and containing mainly offices and labs. The other one represents a building with high occupancy variation and containing mainly lecture rooms and studios. This comparison of the results gives an idea of the different energy saving potential for different types of educational buildings. Principal component analysis is also adopted to investigate the detailed performance of one of the buildings which is influenced stronger by these retrofitting solutions.

Women's experiences of hassles and uplifts in their everyday patterns of occupations.

PubMed

Erlandsson, Lena-Karin; Eklund, Mona

2003-01-01

The aim of this study was to investigate experiences of hassles and uplifts among women. One hundred working mothers were interviewed using the Target Complaints instrument. Content analysis, resulting in both qualitative categories and quantitative variables, was used. Working mothers' hassles were mainly generated by their social, temporal and doing contexts and illustrate the importance of considering women's total patterns of everyday occupations and not focusing one-sidedly on the work situation when treating occupation-related ill-health. Women's uplifts were experienced through the social context and by doing such different occupations as going to the movies, cleaning the house, or attending a class. This indicates the appropriateness of using a client-centred approach in interventions with openness to the client's unique situation. Unexpected occupations were identified almost exclusively among the hassles. This is important knowledge for occupational therapists since women will continue to be dual workers and at potential risk of developing unbalanced and detrimental patterns of occupations, in turn causing ill health.

Adult children's socioeconomic positions and their parents' mortality: a comparison of education, occupational class, and income.

PubMed

Torssander, Jenny

2014-12-01

Recent research has shown that the parents of well-educated children live longer than do other parents and that this association is only partly confounded by the parent's own socioeconomic position. However, the relationships between other aspects of children's socioeconomic position (e.g., occupational class and economic resources) and parental mortality have not been examined. Using the Swedish Multi-generation Register that connects parents to their children, this paper studies the associations of children's various socioeconomic resources (education, occupation, and income) and parents' mortality. The models are adjusted for a range of parental socioeconomic resources and include the resources of the parents' partners. In addition to all-cause mortality, five causes of death are analyzed separately (circulatory disease mortality, overall cancer, lung cancer, breast cancer, and prostate cancer). The results show net associations between all included indicators of children's socioeconomic position and parents' mortality risk, with the clearest association for education. Children's education is significantly associated with all of the examined causes of death except prostate cancer. Breast cancer mortality is negatively related to offspring's education but not the mothers' own education. To conclude, children's education seems to be a key factor compared with other dimensions of socioeconomic position in the offspring generation. This finding suggests that explanations linked to behavioral norms or knowledge are more plausible than those linked to access to material resources. However, it is possible that children's education - to a greater degree than class and income - captures unmeasured parental characteristics.

CTCF and BORIS (CTCFL), two paralogous mammalian proteins sharing nearly identical DNA binding domains, are thought to function in a mutually exclusive manner in DNA binding and transcriptional regulation. Here we show that these two proteins co-occupy a specific subset of regulatory elements consisting of clustered CTCF binding motifs (termed 2xCTSes). BORIS occupancy at 2xCTSes is largely invariant in BORIS-positive cancer cells, with the genomic pattern recapitulating the germline-specific BORIS binding to chromatin. In contrast to the single-motif CTCF target sites (1xCTSes), the 2xCTS elements are preferentially found at active promoters and enhancers, both in cancer and germ cells. 2xCTSes are also enriched in genomic regions that escape histone to protamine replacement in human and mouse sperm. Depletion of the BORIS gene leads to altered transcription of a large number of genes and the differentiation of K562 cells, while the ectopic expression of this CTCF paralog leads to specific changes in transcription in MCF7 cells. We discover two functionally and structurally different classes of CTCF binding regions, 2xCTSes and 1xCTSes, revealed by their predisposition to bind BORIS. We propose that 2xCTSes play key roles in the transcriptional program of cancer and germ cells.

To investigate the relationship between work in shifts and occupational stress. A total of 5338 employees from 13 companies were investigated by cluster sampling, and occupational stress measuring tools, job content questionnaire, and effort-reward imbalance questionnaire were used to investigate occupational stress factors, stress reaction, and the condition of work in shifts. The employees who worked in shifts accounted for 46.6%. The condition of work in shifts varied significantly across different companies, employees with different individual features (including sex, job title, degree of education, age, working years, smoking, and drinking), and employees with different weekly working times(P<0.01 or P<0.05); health status was associated with work in shifts(P<0.01); compared with the employees who did not work in shifts, those who worked in shifts had significantly lower scores of technology utilization, work control level, psychological need, reward, social support, and job satisfaction(P<0.01 or P<0.05), as well as significantly higher scores of physical demands, effort, depressive symptoms, and negative affectivity(P<0.01). Work in shifts can affect health status, and is associated with occupational stress.

We examined changes over four decades and between ethnic groups in how people define their social class. Changes included the increasing importance of income, decreasing importance of occupational prestige, and the demise of the "Victorian bargain," in which poor people who subscribed to conservative sexual and religious norms could think of themselves as middle class. The period also saw changes (among Whites) and continuity (among Black Americans) in subjective status perceptions. For Whites (and particularly poor Whites), their perceptions of enhanced social class were greatly reduced. Poor Whites now view their social class as slightly but significantly lower than their poor Black and Latino counterparts. For Black respondents, a caste-like understanding of social class persisted, as they continued to view their class standing as relatively independent of their achieved education, income, and occupation. Such achievement indicators, however, predicted Black respondents' self-esteem more than they predicted self-esteem for any other group.

A high level of work-family conflict (WFC) is an important risk factor for physical and mental health problems. Although individual work-related factors for WFC have been extensively studied, relatively little is known about whether occupation and gender affect WFC and how such effects might be generated. Cross-sectional study. This study surveyed 3053 civil servants aged 20-65 years working in a local government in the west coast of Japan in 2003. Logistic regression analyses were used to examine whether there are occupational and gender differences in WFC and to clarify the factors underlying these differences. WFC was higher in professional and technical workers compared with other occupations for both men and women, with age-adjusted odds ratios (ORs) for these workers of 1.29 in men and 2.58 in women. In men, occupational differences in WFC disappeared after adjusting for work and family characteristics (OR = 1.15). In women, significant occupational differences remained in the final model, but after adjusting for work characteristics the adjusted OR for professional and technical workers was reduced to 1.69. Women were more likely than men to experience high WFC (OR = 2.52). After controlling for work characteristics, the gender difference was considerably reduced (OR = 1.68). Work characteristics play a fundamental role in the difference in WFC between not only occupational but also gender differences. Stressful work characteristics among professional and technical workers and among women in all work roles should be addressed to reduce occupational and gender differences in WFC in Japan.

The present review focused on the levels and toxicological status of heavy metals especially chromium (Cr) in the exposed workers from different occupational settings around the globe and in Pakistan. It was found that exposed workers from leather tanning and metal plating units showed elevated levels of Cr than the workers from other occupational settings. Cr and other heavy metals level in biological matrices of the exposed workers in different occupational settings revealed that developing countries are severely contaminated. Occupational settings from the Sialkot district, Pakistan exhibited elevated level of Cr in biological entities of the exposed workers. Review suggested that higher level of Cr exposure to the workers enhance the oxidative stress (reactive oxygen species (ROS) and hydroxyl (OH) radical generation) which may cause; cellular and molecular damage such as genotoxicity and chromosomal aberration formations, and carcinogenic effects. This review will help to understand the Cr contamination mechanisms and associated health implications in different occupational settings around the globe in general and particularly to Pakistan. This study will also assist occupational health and safety management authorities to devise or change the Cr recommended exposure limits (REL) for different occupational settings.

Occupation- and industry-based risks for stroke and ischemic heart disease may vary among Japanese working-aged men. We examined the differences in mortality rates between stroke and ischemic heart disease by occupation and industry among employed Japanese men aged 25-59 years. In 2010, we obtained occupation- and industry-specific vital statistics data from the Japanese Ministry of Health, Labour, and Welfare dataset. We analyzed data for Japanese men who were aged 25-59 years in 2010, grouped in 5-year age intervals. We estimated the mortality rates of stroke and ischemic heart disease in each age group for occupation and industry categories as defined in the national census. We did not have detailed individual-level variables. We used the number of employees in 2010 as the denominator and the number of events as the numerator, assuming a Poisson distribution. We conducted separate regression models to estimate the incident relative risk for stroke and ischemic heart disease for each category compared with the reference categories "sales" (occupation) and "wholesale and retail" (industry). When compared with the reference groups, we found that occupations and industries with a relatively higher risk of stroke and ischemic heart disease were: service, administrative and managerial, agriculture and fisheries, construction and mining, electricity and gas, transport, and professional and engineering. This suggests there are occupation- and industry-based mortality risk differences of stroke and ischemic heart disease for Japanese working-aged men. These differences in risk might be explained to factors associated with specific occupations or industries, such as lifestyles or work styles, which should be explored in further research. The mortality risk differences of stroke and ischemic heart disease shown in the present study may reflect an excessive risk of Karoshi (death from overwork).

A robust socioeconomic gradient in health is well-documented, with higher socioeconomic status (SES) associated with better health across the SES spectrum. However, recent studies of U.S. racial/ethnic minorities and immigrants show complex SES-health patterns (e.g., flat gradients), with individuals of low SES having similar or better health than their richer, U.S.-born and more acculturated counterparts, a so-called “epidemiological paradox” or “immigrant health paradox”. To examine whether this exists among Asian Americans, we investigate how nativity and occupational class (white-collar, blue-collar, service, unemployed) are associated with subjective health (self-rated physical health, self-rated mental health) and 12-month DSM-IV mental disorders (any mental disorder, anxiety, depression). We analyzed data from 1530 Asian respondents to the 2002–2003 National Latino and Asian American Study in the labor force using hierarchical multivariate logistic regression models controlling for confounders, subjective social status (SSS), material and psychosocial factors theorized to explain health inequalities. Compared to U.S.-born Asians, immigrants had worse socioeconomic profiles, and controlling for age and gender, increased odds for reporting fair/poor mental health and decreased odds for any DSM-IV mental disorder and anxiety. No strong occupational class-health gradients were found. The foreign-born health-protective effect persisted after controlling for SSS but became nonsignificant after controlling for material and psychosocial factors. Speaking fair/poor English was strongly associated with all outcomes. Material and psychosocial factors were associated with some outcomes – perceived financial need with subjective health, uninsurance with self-rated mental health and depression, social support, discrimination and acculturative stress with all or most DSM-IV outcomes.

Study objective: Occupational structure represents the unequal geographical distribution of more desirable jobs among communities (for example, white collar jobs). This study examines joint effects of social class, race, and county occupational structure on coronary mortality rates for men, ages 35–64 years, 1988–92, in upstate New York. Design: Upstate New York's 57 counties were classified into three occupational structure categories; counties with the lowest percentages of the labour force in managerial, professional, and technical occupations were classified in category I, counties with the highest percentages were in category III. Age adjusted coronary heart disease (CHD) mortality rates, 35–64 years, (from vital statistics and census data) were calculated for each occupational structure category. Main results: An inverse association between CHD mortality and occupational structure was observed among blue collar and white collar workers, among black men and white men, with the lowest CHD mortality observed among white collar, white men in category III (135/100 000). About two times higher mortality was observed among blue collar than white collar workers. Among blue collar workers, mortality was 1.3–1.8 times higher among black compared with white workers, and the highest rates were observed among black, blue collar workers (689/100 000). Also, high residential race segregation was shown in all areas. Conclusions: Results suggest the importance of community conditions in coronary health of local populations; however, differential impact on subpopulations was shown. Blue collar and black workers may especially lack economic and other resources to use available community services and/or may experience worse working and living conditions compared with white collar and white workers in the same communities.

Occupational medicine: toward a worker/patient empowerment approach to occupational illness.

PubMed

Lax, Michael B

2002-01-01

Clinicians practicing occupational medicine are increasingly confronted with patients who have complex illnesses with chronic nonspecific symptoms. Most clinicians use the traditional tools of biomedicine to diagnose and treat the illness, determine etiology, and assess disability. This article argues that the biomedical approach is inadequate to effectively evaluate and treat occupational illness. After reviewing several critiques of biomedicine, including biopsychosocial, feminist, class, and critical theory/postmodern perspectives, the author offers an alternative approach that builds on aspects of these perspectives as well as the "popular education" work of Paulo Freire. Constraints on, and possibilities for, the development of an alternative approach that attempts to build patients' capacities for transformative action are explored.

The constant increase in the number of solved protein structures is of great help in understanding the basic principles behind protein folding and evolution. 3-D structural knowledge is valuable in designing and developing methods for comparison, modelling and prediction of protein structures. These approaches for structure analysis can be directly implicated in studying protein function and for drug design. The backbone of a protein structure favours certain local conformations which include α-helices, β-strands and turns. Libraries of limited number of local conformations (Structural Alphabets) were developed in the past to obtain a useful categorization of backbone conformation. Protein Block (PB) is one such Structural Alphabet that gave a reasonable structure approximation of 0.42 Å. In this study, we use PB description of local structures to analyse conformations that are preferred sites for structural variations and insertions, among group of related folds. This knowledge can be utilized in improving tools for structure comparison that work by analysing local structure similarities. Conformational differences between homologous proteins are known to occur often in the regions comprising turns and loops. Interestingly, these differences are found to have specific preferences depending upon the structural classes of proteins. Such class-specific preferences are mainly seen in the all-β class with changes involving short helical conformations and hairpin turns. A test carried out on a benchmark dataset also indicates that the use of knowledge on the class specific variations can improve the performance of a PB based structure comparison approach. The preference for the indel sites also seem to be confined to a few backbone conformations involving β-turns and helix C-caps. These are mainly associated with short loops joining the regular secondary structures that mediate a reversal in the chain direction. Rare β-turns of type I’ and II’ are also

Introduction Environmental effectors, such as ultraviolet radiation exposure, infection and stress, have been established as having a role in exacerbating lupus symptoms. However, unpredictable patterns of flare events still remain a mystery. Occupational effectors have also been suggested as having a contributing role; however, they are not widely researched. In this paper we report a pilot study designed to generate focus areas for future research regarding occupational exposures and systemic lupus erythematosus (SLE). Methods The study explored potential links between exposures and the occurrence of patient-reported flare events in 80 Australian women with SLE (American College of Rheumatology (ACR) criteria classified). Specifically, the study assessed the hypothesis that occupational exposure is associated with significant changes in the likelihood of lupus flares. Lifetime employment history was analysed with the Finnish Job Exposure Matrix (FINJEM), 40 different semiquantified exposure class estimates for a wide number of occupations based on probability of exposure (p≥5%=exposed) were analysed with the construction of negative binomial regression models to test relationships between occupational agents and flare days. A backward stepwise elimination was used to generate a parsimonious model. Results Significant associations were noted for exposure classes of manual handling burden, (p=0.02, incidence rate ratio (IRR) 1.01), Iron (p=0.00, IRR 1.37), wood dust (p=0.00, IRR 3.34) and asbestos (p=0.03, IRR 2.48). Conclusion Exposure assessment results indicated that occupations, such as nursing, with a high manual handling burden, posed increased risk to patients with SLE, however, the greatest risk was associated with wood dust and iron exposure with teachers and specialist labourers.

Chronic obstructive pulmonary disease (COPD) most often results from the inhalation of toxic agents. Cigarette smoking still remains the principal cause but the pertinence of occupational COPD is now clearly established. After a brief overview of the epidemiology of this "other COPD", the clinical and functional characteristics are summarized, taking into account recent advances in this field. The combined effects of occupational exposure and tobacco are also considered, providing evidence of the need to continuously reinforce campaigns of education and prevention in occupational COPD.

2018-03-06

There is a considerable gap in epidemiological literature about community mental health showing how psychiatric symptoms are associated with job rank, socioeconomic status, and occupational health. We examine data from 4596 employees collected in the United Kingdom's Psychiatric Morbidity among Adults Living in Private Households Survey. There were 939 workers in managerial jobs, 739 in supervisory jobs and 2918 employees in lower ranking jobs. Of the 4596 workers, 2463 had depressive symptoms and 2133 no depressive symptoms. Job rank, household gross income, social class, personal gross income and socio-economic group were significantly associated with general health, occupational health and depressive and avoidant symptoms. Job rank, occupational and physical health also explained the variance in paranoid and avoidant symptoms among the employees. This study shows that severe psychopathology is related to workers' job rank.

We sought to examine the association between reasons for early retirement and health status and to assess whether this association differs by gender and social class. The sample was all people currently working or retired between 50 and 64 years of age (2,497 men and 1,420 women) who were interviewed in the 2006 Spanish National Health Survey. The health outcomes analyzed were self-perceived health status and mental health. Multiple logistic regression models stratified by gender and occupational social class were fitted. Female manual workers who were forced into early retirement due to organizational reasons were more likely to report poor self-perceived health status (adjusted odds ration [aOR], 4.04; 95% confidence interval [CI], 1.44-11.32) and poor mental health (aOR, 2.70; 95% CI, 1.15-6.33), whereas no such association was observed among male workers or among female nonmanual workers. Early retirement on health grounds was associated with both health outcomes in all groups, but retirement because of age, voluntary retirement, and retirement for other reasons were not related to poor health outcomes in any group analyzed. Forced early retirement owing to organizational reasons is related to poor health indicators only among female manual workers. Results highlight the importance of paying more attention to the potential vulnerability of female manual workers in downsizing processes as well as in early retirement policies.

Class advantage and the gender divide: flexibility on the job and at home.

PubMed

Gerstel, Naomi; Clawson, Dan

2014-09-01

Using a survey, interviews, and observations, the authors examine inequality in temporal flexibility at home and at work. They focus on four occupations to show that class advantage is deployed in the service of gendered notions of temporal flexibility while class disadvantage makes it difficult to obtain such flexibility. The class advantage of female nurses and male doctors enables them to obtain flexibility in their work hours; they use that flexibility in gendered ways: nurses to prioritize family and physicians to prioritize careers. Female nursing assistants and male emergency medical technicians can obtain little employee-based flexibility and, as a result, have more difficulty meeting conventional gendered expectations. Advantaged occupations "do gender" in conventional ways while disadvantaged occupations "undo gender." These processes operate through organizational rules and cultural schemas that sustain one another but may undermine the gender and class neutrality of family-friendly policies.

2013-01-01

The cause of sporadic amyotrophic lateral sclerosis (SALS) remains unknown. We attempted to find out if occupational exposure to toxicants plays a part in the pathogenesis of this disease. In an Australia-wide case-control study we compared the lifetime occupations of 611 SALS and 775 control individuals. Occupations were coded using country-specific as well as international classifications. The risk of SALS for each occupation was calculated with odds ratios using logistic regression. In addition, the literature was searched for possible toxicant links between our findings and previously-reported occupational associations with SALS. Male occupations in our study that required lower skills and tasks tended to have increased risks of SALS, and conversely, those occupations that required higher skills and tasks had decreased risks of SALS. Of all the occupations, only truck drivers, where exposure to diesel exhaust is common, maintained an increased risk of SALS throughout all occupational groups. Another large case-control study has also found truck drivers to be at risk of SALS, and almost two-thirds of occupations, as well as military duties, that have previously been associated with SALS have potential exposure to diesel exhaust. In conclusion, two of the largest case-control studies of SALS have now found that truck drivers have an increased risk of SALS. Since exposure to diesel exhaust is common in truck drivers, as well as in other occupations that have been linked to SALS, exposure to this toxicant may underlie some of the occupations that are associated with SALS.

2007-01-01

Objectives To provide a framework for epidemiological research on work and health that combines classic occupational epidemiology and the consideration of work in a structural perspective focused on gender inequalities in health. Methods Gaps and limitations in classic occupational epidemiology, when considered from a gender perspective, are described. Limitations in research on work related gender inequalities in health are identified. Finally, some recommendations for future research are proposed. Results Classic occupational epidemiology has paid less attention to women's problems than men's. Research into work related gender inequalities in health has rarely considered either social class or the impact of family demands on men's health. In addition, it has rarely taken into account the potential interactions between gender, social class, employment status and family roles and the differences in social determinants of health according to the health indicator analysed. Conclusions Occupational epidemiology should consider the role of sex and gender in examining exposures and associated health problems. Variables should be used that capture the specific work environments and health conditions of both sexes. The analysis of work and health from a gender perspective should take into account the complex interactions between gender, family roles, employment status and social class. PMID:18000116

Social class, income, education, area of residence and psychological distress: does social class have an independent effect on psychological distress in Antalya, Turkey?

PubMed

Belek, I

2000-02-01

The aim of this study is to determine the separate effects of social class, income, education and area of residence on psychological distress. The study also assesses whether the association between prevalence of high score on the 12-item General Health Questionnaire (GHQ 12) and social class is independent of other variables. Psychological distress was assessed by means of the GHQ 12. The study covered 1,092 adults aged 15 years or more living in two different quarters of Antalya. Social class status was defined by occupational position, with income, education and area of residence treated as confounders. Chi-square and logistic regression analyses were used to evaluate the data. Large inequalities in psychological distress by all variables were observed. Psychological distress was significantly associated with class status, after adjusting for income, education, area of residence and other potential confounders (age, sex and marital status). Class inequalities in psychological distress were observed between blue-collar workers/unqualified employees and bourgeoisie. These findings support the view that the recent widening of inequalities among social classes in Turkey pose a substantial threat to health.

Nevertheless, the unequal distribution and participation in the labor markets between men and women should be kept in mind. The purpose was to assess the gender impact in the recognition of OD in Spain, examining interaction and confounding factors. An incidence study of the occupational diseases declared through the official OD reporting forms from 1999 to 2009, provided by the General Subdirectorate of Social and Labor Statistics of the Ministry of Employment and Social Security, was conducted. The variables included were: reporting year, sex, age, occupation and economic activity of the company. Rates and crude relative risks (cRR) by these variables were calculated. Adjusted RR were also computed by using multivariate Poisson regression. During the study period a total of 243,310 OD were reported in Spain, with a sex ratio of men to women of 1.07. Correlation existed between occupation and business activity, thus the OD rates and RR were computed by these variables separately. By occupation, men had a crude RR of 1.067 (95%CI:1.058 to 1.076) versus women, while wen the analysis was adjusted by all the variables, the RR was 0.507 (95%CI:0.502 to 0.512). By economic activity of the company, the sense of risk was reversed too in the adjusted analysis (cRR=1.065, 95%CI:1.056 to 1.074 versus 0.632, 95%CI:0.626 to 0.638). Although crude OD rates were lower in women than in men during the period 1999-2009 in Spain, when these rates were adjusted by company activity or worker occupation, age and year of OD declaration, RRs become almost 50% higher in women than in men for the majority of occupations and types of company activity.

Objective: To investigate hearing loss status of blasters, drillers mechanics and so on in underground mining, and put forward suggestion diagnosis of occupational explosive deafness and occupational deafness. Methods: Underground excavation workers in a metal mine were recruited in this study, those with a history of ear disease and non-occupational deafness were all excluded. Finally, the features of pure tone audiometry of 459 noise-exposed workers were analyzed. Results: High-frequency hearing loss occurred on 351workers and the positive detection rate was 74.29%, workers who had both high-frequency and linguistic frequency hearing loss were 51 and the positive detection rate was 11.11%. The positive detection of high-frequency hearing loss in right ear (χ(2)=9.427 and P = 0.024) and in left ear (χ(2)=14.375, P =0.002) was significantly different between different exposure age groups. The positive detection of high-frequency hearing loss of driving group was the highest, followed by blasting group, mining group and machine repair group. The characteristics of the hearing loss caused by drilling noise of the blasting workers with no accident occurred were in line with that of noise-induced hearing loss. Conclusion: The diagnosis grading should be carried out according to the diagnostic criteria of occupational noise-induced deafness for the employees who engaged in the blasting operation with no record of blast accident.

Little is known about the distribution by occupation of chronic illness, disability, morbidity, and lifestyles which put health at risk. To provide a map of the social inequalities in various dimensions of health and lifestyle by social class and for specific occupational groups. To formulate a hypothesis about the mechanisms which generate these inequalities. Prevalence rate ratios and prevalence odds ratios of perceived health, chronic illness, disability, absenteeism, trauma, smoking, and obesity calculated with data from the 1999-2000 Italian ISTAT (Central Statistics Institute) health survey; the study population includes adults (aged over 18 years) employed, or searching for a job, or withdrawn from the workforce. Among workers in manual unskilled labour, construction and agriculture are noted for worse health and more unhealthy lifestyles than average. For example, perceived bad health is more widespread among agricultural labourers (OR = 1.63), masons and construction machine operators (OR = 1.75), transport drivers (OR = 1.40), male caretakers, custodians, janitors and domestic help (OR = 1.46), electro-technicians (OR = 1.44), leatherworkers and shoemakers (OR = 3.58), miners and quarrymen (OR = 2.60), earthenware and stone workers (OR = 2.14), garment and furnishings workers (OR = 1.86); in female workers excess risk for perceived bad health was present among agricultural labourers (OR = 2.08), caretakers, custodians, janitors and domestic helpers (OR = 1.49), waitresses, cooks and bartenders, (OR = 1.44), and textile workers (OR = 1.67). Smoking was more widespread among chemical workers (OR = 1.41), and in miners and quarrymen (OR = 1.30). An excess risk of smoking of 20-25% was evident in spinners, weavers and finishers; masons, (and) builders; waiters, cooks and bartenders; garment and furnishings workers; porters and warehouse workers. The risk was 10% higher among foundry workers and forgers, plumbers, carpenters and welders, and transport drivers

Occupational Consciousness.

PubMed

Ramugondo, Elelwani L

2015-10-02

Occupational consciousness refers to ongoing awareness of the dynamics of hegemony and recognition that dominant practices are sustained through what people do every day, with implications for personal and collective health. The emergence of the construct in post-apartheid South Africa signifies the country's ongoing struggle with negotiating long-standing dynamics of power that were laid down during colonialism, and maintained under black majority rule. Consciousness, a key component of the new terminology, is framed from post-colonial perspectives - notably work by Biko and Fanon - and grounded in the philosophy of liberation, in order to draw attention to continuing unequal intersubjective relations that play out through human occupation. The paper also draws important links between occupational consciousness and other related constructs, namely occupational possibilities, occupational choice, occupational apartheid, and collective occupation. The use of the term 'consciousness' in sociology, with related or different meanings, is also explored. Occupational consciousness is then advanced as a critical notion that frames everyday doing as a potentially liberating response to oppressive social structures. This paper advances theorizing as a scholarly practice in occupational science, and could potentially expand inter or transdisciplinary work for critical conceptualizations of human occupation.

In this study, the relationship between occupational stress and suicidal ideation was investigated, focusing on gender differences among Korean employees. Cross-sectional data for 53,969 workers were collected at Kangbuk Samsung Hospital health screening centers. Risk of suicidal ideation was assessed using a self-reported questionnaire examining suicidal ideation during the past year. Occupational stress was measured using 24 items of the Korean Occupational Stress Scale-Short Form (KOSS-SF). Logistic regression analysis was employed to estimate the odds ratios and 95% confidence intervals of the relationships between suicidal ideation and components of occupational stress. In multivariable-adjusted models, all job stress contributed to increased risk of suicidal ideation in males. Most subscales, except insufficient job control and organizational system, were risk factors of suicidal ideation in females. Further adjustments for depression markedly attenuated this relationship. However, the effects of insufficient job control and lack of reward on suicidal ideation remained significant in males, and interpersonal conflict remained significant in females. The results suggest that occupational stress plays a significant role in increasing risk of suicidal ideation through elevation of depressive symptoms. Gender differences in components of occupational stress associated with suicidal ideation were also observed.

To analyze gender inequalities in employment and working conditions, the work-life balance, and work-related health problems in a sample of the employed population in Spain in 2007, taking into account social class and the economic sector. Gender inequalities were analyzed by applying 25 indicators to the 11,054 workers interviewed for the VI edition of the National Working Conditions Survey. Multivariate logistic regression models were used to calculate odds ratios (OR) and 95% confidence intervals (95% CI), stratifying by occupational social class and economic sector. More women than men worked without a contract (OR=1.83; 95% CI: 1.51-2.21) and under high-effort/low-reward conditions (1.14:1.05-1.25). Women also experienced more sexual harassment (2.85:1.75-4.62), discrimination (1.60:1.26-2.03) and musculoskeletal pain (1.38:1.19-1.59). More men than women carried out shift work (0.86:0.79-0.94), with high noise levels (0.34:0.30-0.40), and high physical demands (0.58:0.54-0.63). Men also suffered more injuries due to occupational accidents (0.67:0.59-0.76). Women white-collar-workers were more likely than their male counterparts to have a temporary contract (1.34:1.09-1.63), be exposed to psychosocial hazards and discrimination (2.47:1.49-4.09) and have occupational diseases (1.91:1.28-2.83). Gender inequalities were higher in the industry sector. There are substantial gender inequalities in employment, working conditions, and work-related health problems in Spain. These gender inequalities are influenced by social class and the economic sector, and should be considered in the design of public policies in occupational health. Copyright © 2011 SESPAS.

There is limited evidence on the influence of social determinants on the self-perceived and mental health of immigrants settled at least 8 years in Spain. The aim of this study was to examine differences between workers related to migrant-status, self-perceived and mental health, and to assess their relationship to occupational conditions, educational level and occupational social class, stratified by sex. Using data from the Spanish National Health Survey of 2011/12, we computed prevalence, odds ratios and explicative fractions. Mental (OR 2.02; CI 1.39-2.93) and self-perceived health (OR 2.64; CI 1.77-3.93) were poorer for immigrant women compared to natives. Occupational social class variable contributes 25% to self-perceived health OR in immigrant women. Settled immigrant women workers are a vulnerable group in Spain.

The present study examines gender differences in occupations, occupational hazards, and musculoskeletal symptoms in Korean workers. We performed a secondary analysis of data from the fourth Korean Working Conditions Survey (KWCS). Relative to "managers," men who were "craft and related trades workers," "equipment, machine operating and assembling workers," and in "elementary occupations" were more likely to report back pain (ORs: 2.08, 2.33, and 2.71, respectively); women who were "skilled agricultural, forestry, and fishery workers" were more likely to report back pain (OR: 3.96). Back pain was more likely to be reported in men exposed to "carrying/moving heavy loads," "painful/tiring postures," and "repetitive hand/arm movements" (ORs: 1.20, 2.26, and 1.28, respectively). Men and women workers differed in their reporting of ergonomic risk factors, and complaints of musculoskeletal symptoms. Am. J. Ind.

We investigated the extent to which smoking status was associated with exposure to occupational (e.g., dust, chemicals, noise, and ergonomic strain) and social (e.g., abuse, sexual harassment, and racial discrimination) workplace hazards in a sample of U.S. multiethnic working-class adults. United for Health is a cross-sectional study designed to investigate the combined burden of occupational and social workplace hazards in relation to race/ethnicity, gender, and wage and to evaluate related health effects in a working-class population. Using validated measures, we collected data from 1,282 multiethnic working-class participants using audio computer-assisted interviews. We used multiple imputation methods to impute data for those missing data. Crude and adjusted logistic odds ratios (ORs) were modeled to estimate ORs and 95% confidence intervals (CIs). The prevalence of smoking was highest among non-Hispanic white workers (38.3%) and lowest for foreign-born workers (13.1%). We found an association between racial discrimination and smoking (OR = 1.12, 95% CI 1.01, 1.25). The relationship between smoking and sexual harassment, although not significant, was different for black women compared with men (OR = 1.79, 95% CI 0.99, 3.22). We did not find any associations by workplace abuse or by any of the occupational hazards. These results indicate that racial discrimination might be related to smoking in working-class populations and should be considered in tobacco-control efforts that target this high-risk population.

The relative importance of social class and maternal education for breast-feeding initiation.

Skafida, Valeria

2009-12-01

To examine changes in breast-feeding take-up rates among young children in Scotland and to assess whether maternal education or occupation-based social class is a stronger and better predictor of breast-feeding take-up. Binary logistic regression models were developed from the first sweep of the Growing Up in Scotland longitudinal survey, for the two cohorts of children. A national representative survey for Scotland. A baby cohort of 5012 singletons born over a 12-month period between June 2004 and May 2005, and a toddler cohort of 2732 singletons born over a 12-month period between June 2002 and May 2003. Mothers from more privileged social classes and those with more educational qualifications resulted as more likely to breast-feed. However, maternal education was a better and more robust predictor of breast-feeding take-up compared with social class. There were no significant differences in breast-feeding take-up between the two cohorts and only minor differences between mothers aged 20-29 years and those who stated an intention to bottle-feed prior to birth. The study suggests that the importance of maternal education in influencing breast-feeding has been somewhat overlooked in research based in more developed countries. The results indicate that, compared with occupation-related social class, maternal education is a more informative, accurate and useful lens through which to understand and explain patterns of breast-feeding take-up.

Social class differences in self, attribution, and attention: socially expansive individualism of middle-class Americans.

Although U.S. culture strongly sanctions the ideal of independence, the specific ways in which independence is realized may be variable depending, among other factors, on social class. Characterized by relative scarcity of social and material resources, working-class (WC) Americans were expected to strongly value self-reliance. In contrast, with choices among abundant resources, middle-class (MC) Americans were expected to value personal control and social expansiveness. In support of this analysis, relative to their WC counterparts, MC Americans reported more support from friends and greater likelihood of giving and receiving advice but less self-reliance (Study 1). Furthermore, we found evidence that this social difference has cognitive consequences: College students with MC backgrounds were more likely than their WC counterparts were to endorse situational attributions for others' behavior (Studies 2a and 2b) as well as to show holistic visual attention (Study 3).

Gender differences in occupational mobility and structure of employment in the British Civil Service.

In all industrialized societies health status in adults has been found to vary with social position. Attempts to explain this are usually grouped under headings of artefact, material, lifestyle and selective mobility of the healthiest. Such attempts have to date been unsuccessful in fully accounting for this relationship, and whilst they have merit have left unconsidered the effects of the process whereby social stratification occurs. The present study is a prelude to subsequent studies that will endeavour to distinguish between three separate influences on health--the effects of current social position, the long term effects stemming from one's initial class position, and the effects of the processes governing mobility. The purpose of our present investigation is to describe patterns of occupational mobility, that will enable us to identify possible predictors of subsequent mobility and therefore to indicate to what extent mobility might be a process governed by social rules. The work presented in this paper comprises part of the Whitehall II study of occupational, social and lifestyle influences upon health in a Civil Service population. Using multiple regression techniques almost half the variation in mobility is modelled in terms of educational level, fathers' social class, gender, marital status, age on entry into the Civil Service, length of time in Civil Service employment and grade of entry into the Civil Service. Using estimates derived from this model it is suggested that a number of sub-groups within the Civil Service suffer adverse mobility (mobility appears particularly restricted for women and for those entering the Civil Service above 30 years of age). The results obtained suggest that the issue of obstructed opportunity at the workplace could become a focus for fruitful investigation, linking issues of personal autonomy, expectations and control to health. A number of methodological problems in this kind of work are considered together with

Biomechanical evaluation of occupant anthropometry during frontal collisions.

The present study examines the biomechanical implications of 3-point lap/shoulder seat belts and frontal air bags to the injury probabilities for occupants of varying anthropometry, during frontal collisions. Using Mathematical Dynamic Modeling (MADYMO) software, a variety of simulated frontal crash tests were conducted to evaluate the effectiveness of seat belts and air bags in reducing probability of injury to different sized occupants. The simulations included virtual models of the 5th percentile female, 50th percentile male, and 95th percentile male to represent three occupant size classes. The test matrix paired each of these dummy sizes with four restraint system configurations. The configurations examined were seat belt only, air bag only, both seat belt and air bag, and none. Each of the simulated crashes was modeled to replicate a direct (12 O'clock) frontal collision with a total change in velocity of 56.3kph. Likelihood of serious injury was determined through the calculation of Head Injury Criteria (HIC,36ms), angular acceleration of the head center of gravity, and the Nij neck injury criteria. The results generally suggested that air bags produce a more significant reduction in HIC for larger belted occupants than they do for smaller belted occupants, and that whether belted or not, smaller occupants received the largest reduction in head CG angular acceleration due to the existence of an air bag. Though clear trends were not noted in the neck injury values, it was noted that the simulations with out air bags produced two results that failed the injury criterion, while no serious neck injuries would be expected based on the values produced in the simulations with air bags. The study suggested that a properly timed air bag deployment can reduce injury potential for all occupants of all sizes, but that the magnitude of this benefit is dependent on anthropometry.

AIM—To examine the influence of socioeconomic status on growth pattern in height from age 7 to 23years.
METHODS—Prospective cohort study. A total of 10 200 white singleton born children from the 1958 British birth cohort (National Child Development Study) were analysed.
RESULTS—Differences in height by birth weight persisted throughout the follow up period. However, the mean differences in height between low birth weight infants (<2500 g) and adequate birth weight infants (⩾2500 g) were less notable in social classes I and II than in the lower social classes. The catching up of growth in height of low birth weight infants was also more pronounced in social classes I and II than in other social classes. That is, the mean height deficits of low birth weight infants were decreased from 2.9 cm at age 7, to 1.6 cm at age 16, and 2.5 cm at age 23; the significant difference disappeared after age 16 in social classes I and II. Although such improving tendency was more pronounced among the preterm born infants, a similar growth pattern was observed among the term infants. Such improvement was not observed in the other social classes.
CONCLUSION—The growth retardation in height by birth weight can be overcome by improved social conditions and proper health care from childhood to adulthood.

The occupational aspirations and expectations of two populations of boys in grades 2, 4, 6, and 8 were examined in order (1) to describe what is unique about the development of job preferences among urban ghetto children who live in settings where many adult males are not well attached to the labor force and (2) to examine 6 reasons for any age- and population-dependent patterns there might be in job aspirations and job expectations. Findings show that boys tend to be more realistic about occupational aspirations and expectations the older they are; that from second grade on the occupational expectations of inner-city boys mirror existing race and class differences in adult job holdings; that the gap between occupational aspirations and expectations is greater for the ghetto boys and remains roughly constant in size across the grades examined; and that the lower occupational expectations of the inner-city boys are strongly related to their lower educational expectations, with these educational expectations being associated with fewer poor boys having a biological father at home and with more of these boys seeing obstacles to success in the local social setting. But, the lower occupational expectations of the ghetto boys are not due to having fewer positive role models or believing that schooling will not pay off for them in the future as it does for others.

Gender Differences in Perceptions of Resources and Turnover Intentions of Work-Linked Couples in Masculine Occupations.

Huffman, Ann Hergatt; Olson, Kristine J

2017-10-01

Employees in work-linked marriages have spouses that share the same family and the same workplace and/or occupation. Whereas, in recent years, there has been increasingly more research on dual-career marriages (i.e. both spouses work, but not necessarily at the same workplace and/or occupation), there has been very little research on work-linked marriages. The current study focuses on work resources (i.e. family supportive supervisor behaviour and job control) as key mediating processes that explain the effect of gender on turnover intentions among work-linked employees in masculine occupations (i.e. military). Investigating gender differences is important because, compared with men, women are more likely to be in work-linked marriages and to leave their jobs. Based on role theory and conservation of resource theory, we predicted that gender was related to turnover intentions, and this relationship would be mediated by key explanatory variables (i.e. family supportive supervisor behaviours, job control and psychological distress). Mediation analyses, conducted on a sample of men and women in work-linked marriages (n = 309), provide support for the hypothesized model. These findings offer guidance for understanding gender differences among work-linked employees in masculine occupations, and how these differences can affect important outcomes such as turnover intentions.

Few studies have been aimed at describing organizational and psychosocial conditions of the Italian workforce by occupational group, and they have been mainly conducted within specific occupations. The present study aimed at identifying specific groups of occupations which have unfavourable profiles from the point of view of exposure to specific organizational factors and psychosocial risks, and to physical, chemical and ergonomic risks, and analyzing their distribution by worker age. The analysis was conducted on a sample of 4,195 workers in the Piedmont Region who were members of the CGIL Trade Union (Italian General Confederation of Labour), who answered a self-administered questionnaire in 2000, aimed at assessing chemical, physical, and ergonomic risks, accidents, and psychosocial factors connected with work organization and work tasks. Psychosocial risks were assessed via three scales aimed at measuring the degree of control, psychophysical demands, and worker satisfaction. The proportion of workers exposed to the above mentioned risks was analysed according to occupational group. This group was then compared with all other groups taken together, according to prevalence of high strain condition (combination of high demand and low control) and HSUR condition (High Strain Unfairly Rewarded; combination of high strain and low satisfaction). Among males aged 25-44 years, restricted to the occupation groups with more than ten workers in high strain condition, significantly higher proportions of stress were observed in leather workers and shoemakers, paper factory workers, rubber workers, crane and bridge crane operators, plastic workers, painters, transport drivers and carpenters. For many of these groups, excesses were confirmed for the HSUR condition. Among subjects aged over 44 years, a higher risk for high strain was confirmed in rubber workers, transport drivers and carpenters. In addition, machine tool operators, assembly line and mechanical workers in this

The use of online teaching tools facilitate the incorporation of self-learning methods. With a view to encouraging convergence in teaching tools and methods in Occupational Legal Medicine, an initiative was set up within the classes of Legal and Forensic Medicine at Saragossa University, as part of the EU funded NetWoRM project, which has been led since 1999 by Ludwig-Maximilians-Universität in Munich (Germany). The interest of medical students in Occupational Legal Medicine has so far been low and in addition different aspects complicate the teaching of Occupational Legal Medicine at medical schools: One reason for the low interest is the limited availability of bedside teaching, one of the students' most favourite and effective way to learn. The reason for that is that most medical schools with occupational departments only have outpatient clinics. "Interesting" patients who be need for educational purposes are therefore only available for a limited part of the day. However, in order to recognize and prevent occupational disorders each medical student and physician needs profound clinical knowledge in Occupational Legal Medicine. This project has proven to be highly efficient in permitting the creation and validation of teaching tools which cover and improve the traditional training of the Occupational Legal Medicine programme imparted in the degree of Medicine.

Job control and burnout across occupations.

2005-12-01

Researchers have reported that, for individual workers, low job control is associated with high burnout; however, as yet it is unclear whether this association holds for occupations as well. Whether differences in job control between occupations as assessed by eight expert judges could account for individual-level and occupational-level differences in burnout rates. Data were obtained from 9,503 incumbents of 28 occupations in The Netherlands (M age = 37.9 yr., SD = 8.7; 50% were men). Burnout was measured on the Maslach Burnout Inventory. Occupational-level job control was inversely correlated with burnout, explaining 16% of the variation in occupational-level burnout. Thus, between-occupation differences in job control are somewhat systematically related to burnout.

With deployment Soldiers must now wear body armor and additional equipment while performing occupational tasks, representing a large demand that has not been considered when studying military occupations. The purpose of this study was to: (1) describe tasks required by different occupational battalions within a Brigade Combat Team; (2) establish the incidence of low back pain (LBP) in each battalion and; (3) determine which tasks predict LBP within the different battalions. This was a prospective cohort study investigating 805 Soldiers in a Brigade Combat Team deployed to Afghanistan for 1 year. Demographic, occupational, and fitness variables were recorded. There was no difference in time spent on fitness training between the battalions. Occupational tasks performed by deployed Soldiers vary in the level of physical demand between battalions. Infantry had the highest fitness score (257); wore the heaviest equipment (70 lb.); spent the most time wearing body armor (49 hours/week), performing dismounted patrol (29 hours/week), and lifting objects (35 hours/week); spent the least amount of time working at a desk (14 hours/week); but had a similar incidence of LBP (77%) compared to other battalions. History of LBP and time spent wearing body armor were the two most consistent predictors of LBP across battalion types. Reprint & Copyright © 2013 Association of Military Surgeons of the U.S.

A wide body of evidence indicates that environmental and occupational risk factors are associated with the development of pathological disorders. The pathogenic role of many environmental pollutants or occupational contaminants is already known and has been extensively investigated. However, the molecular mechanisms of action and the pathogenic effects of many substances remain unknown. Therefore, there is a need to better investigate the role of new environmental and occupational risk factors that may cause the development of several diseases.

Life satisfaction research in China is in development, requiring new perspectives for enrichment. In China, occupational mobility is accompanied by changes in economic liberalization and the emergence of occupational stratification. On the whole, however, occupational mobility has rarely been used as an independent variable. Health status is always used as the observed or dependent variable in studies of the phenomenon and its influencing factors. A research gap still exists for enriching this field. The data used in this study were obtained from the China Health and Nutrition Survey (CHNS). The study included nine provinces in China. The survey was conducted from 1989 to 2009.Every survey involved approximately 4400 families or 19,000 individual samples and parts of community data. First, we built a 5 × 5 social mobility table and calculated life satisfaction of Chinese residents of different occupations in each table. Second, gender, age, marital status, education level, annual income and hukou, health status, occupational mobility were used as independent variables. Lastly, we used logistic diagonal mobility models to analyze the relationship between life satisfaction and the variables. Model 1 was the basic model, which consisted of the standard model and controlled variables and excluded drift variables. Model 2 was the total model, which consisted of all variables of interest in this study. Model 3 was the screening model, which excluded the insignificant drift effect index in Model 2. From the perspective of the analysis of controlled variables, health conditions, direction, and distance of occupational mobility significantly affected life satisfaction of Chinese residents of different occupations. (1) From the perspective of health status, respondents who have not been sick or injured had better life satisfaction than those who had been sick or injured. (2) From the perspective of occupational mobility direction, the coefficients of occupational

Differences in antigen presentation to MHC class I-and class II- restricted influenza virus-specific cytolytic T lymphocyte clones

PubMed Central

1986-01-01

We have examined requirements for antigen presentation to a panel of MHC class I-and class II-restricted, influenza virus-specific CTL clones by controlling the form of virus presented on the target cell surface. Both H-2K/D- and I region-restricted CTL recognize target cells exposed to infectious virus, but only the I region-restricted clones efficiently lysed histocompatible target cells pulsed with inactivated virus preparations. The isolated influenza hemagglutinin (HA) polypeptide also could sensitize target cells for recognition by class II-restricted, HA-specific CTL, but not by class I-restricted, HA- specific CTL. Inhibition of nascent viral protein synthesis abrogated the ability of target cells to present viral antigen relevant for class I-restricted CTL recognition. Significantly, presentation for class II- restricted recognition was unaffected in target cells exposed to preparations of either inactivated or infectious virus. This differential sensitivity suggested that these H-2I region-restricted CTL recognized viral polypeptides derived from the exogenously introduced virions, rather than viral polypeptides newly synthesized in the infected cell. In support of this contention, treatment of the target cells with the lysosomotropic agent chloroquine abolished recognition of infected target cells by class II-restricted CTL without diminishing class I-restricted recognition of infected target cells. Furthermore, when the influenza HA gene was introduced into target cells without exogenous HA polypeptide, the target cells that expressed the newly synthesized protein product of the HA gene were recognized only by H-2K/D-restricted CTL. These observations suggest that important differences may exist in requirements for antigen presentation between H-2K/D and H-2I region-restricted CTL. These differences may reflect the nature of the antigenic epitopes recognized by these two CTL subsets. PMID:3485173

Domestic violence is a medical and social issue that often leads to negative consequences for society. This paper examines the association between the prevalence of domestic violence in relation to the different socio-economic classes in Central Trinidad. The paper also explores the major perceived causes of physical abuse in Central Trinidad. Participants were selected using a two-stage stratified sampling method within the Couva district. Households, each contributing one participant, were stratified into different socioeconomic classes (SES Class) and each stratum size (or its share in the sample) was determined by the portion of its size in the sampling frame to the total sample; then its members were randomly selected. The sampling method attempted to balance and then minimize racial, age, cultural biases and confounding factors. The participant chosen had to be older than 16-years of age, female and a resident of the household. If more than one female was at home, the most senior was interviewed. The study found a statistically significant relationship between verbal abuse (p = 0.0017), physical abuse (p = 0.0012) and financial abuse (p = 0.001) and socio-economic class. For all the socio-economic classes considered, the highest prevalence of domestic violence occurred amongst the working class and lower middle socio-economic classes. The most prominent reasons cited for the physical violence was drug and alcohol abuse (37%) and communication differences (16.3%). These were the other two main perceived causes of the violence. The power of the study was 0.78 and the all strata prevalence of domestic violence was 41%. Domestic violence was reported within all socio-economic class groupings but it was most prevalent within the working class and lower middle socio-economic classes. The major perceived cause of domestic violence was alcohol/drug abuse.

Serial peak expiratory flow (PEF) records have been recommended as a first-line investigation in workers suspected as having occupational asthma (OA). To determine which PEF variability index best differentiates workers with OA from non-occupational asthmatics and unaffected irritant-exposed workers. PEF was measured at least four times daily for at least 3 weeks in three groups of subjects: (i) forty healthy grain-exposed farmers and dockers, (ii) forty-two consecutive workers with independently confirmed OA and (iii) forty-eight non-occupational asthmatics. Indices of PEF variability were compared between groups. The difference in mean PEF between rest and work periods best separated the occupational asthmatic workers from the others. The upper 95% confidence limit of this index for grain-exposed workers was 2.8% of predicted PEF (16 l/min) and 3.3% (15 l/min) for non-occupational asthmatics. Sensitivity for diagnosing OA using this index was 70%. An increase in diurnal variation on workdays of >7% had a sensitivity of only 27% for the diagnosis of OA. The difference between maximum PEF on workdays and minimum PEF on rest days had a sensitivity of <10% against non-occupational asthmatic controls. Difference in mean PEF between workdays and rest days is the best simple index for differentiating subjects with OA from those with non-OA or irritant-exposed healthy subjects. Differences >16 l/min are unlikely to be due to significant irritant exposure in healthy workers.

Low education is consistently associated with an increased risk of back pain disability, but the underlying mechanisms for this relationship are poorly understood. In a seven-year prospective observational study of 38,426 employed men and women between 25 and 59 years in Norway, we investigated to what extent occupational class, working conditions and individual lifestyle mediated the effect of formal education on disability pensioning from back pain. Each additional year of formal education was associated with decreased risk for disability pensioning from back pain for both men [age adjusted Hazard Ratio (HR) 0.77; (95% Confidence Interval, 0.72-0.82)] and women [HR 0.76(0.71-0.82)]. Adjustment for occupational class and factors related to working conditions (authority to plan own work, physically demanding work, concentration and attention and job satisfaction) and individual lifestyle (smoking, body mass index, physical exercise and alcohol consumption) reduced the effect of education by 39% [HR 0.86(0.79-0.93)] for men and by 21% [HR 0.81(0.73-0.89)] for women. Working conditions contributed most to the explanation for men, while occupational class, working conditions and life style factors contributed equally for women. Subgroup analyses indicate small differences between full-time and part-time employees, while some differences were found between subcategories of back diseases. The study indicates that there is a strong and unexplained effect of education on back pain disability pensioning, which is not mediated by occupational class, working conditions or individual lifestyle.

Rooted in the neurodiversity approach, this study provides an overview of the strengths and interests of individuals with Asperger's Syndrome. We interviewed 136 individuals with Asperger's Syndrome and 155 neurotypical individuals via an online survey with regards to (a) demography, (b) occupational strengths, (c) general self-efficacy, (d) occupational self-efficacy, and (e) the job interest profile according to Holland. The vocational and educational fields of the individuals with Asperger's in the sample are more diverse than and surpass those classical fields stated in research and biographical literature. The comparison of both groups in cross-tables showed that the indicated strengths differ in several areas (ΦCramer = .02-.47), which means that a specific strength profile can be derived, and this profile goes beyond the clinical view of the diagnostic criteria. Individuals with Asperger's indicate lower self-efficacy, both general and occupational. Furthermore, a high concentration of individuals with Asperger's can be found in the areas I (Investigative) and C (Conventional) of Holland's RIASEC model.

Casper, M; Wing, S; Strogatz, D

1991-01-01

STUDY OBJECTIVE--The aim was to examine the patterns of black-white differences in stroke mortality across communities with varying levels of occupational structure in the southern region of the United States DESIGN--Annual age adjusted race-sex specific rates for stroke mortality were calculated for the years 1979-1981 and related to socioeconomic conditions. SETTING--The study involved 211 state economic areas comprising the southern region of the USA. STUDY POPULATION--Data on stroke mortality for black and white men and women between the ages of 35 and 74 years living in the study area were acquired from the National Center for Health Statistics. MEASUREMENTS AND MAIN RESULTS--Occupational structure was measured as the proportion of white collar workers in each state economic area, and is an indicator of the employment opportunities and related social and economic resources of a community. Stratified analyses and linear regression modelling indicate that communities of lower occupational structure have (a) higher levels of stroke mortality for all four race-sex groups (p less than 0.05) and (b) larger racial inequalities in stroke mortality (p less than 0.01). For men and women, the excess stroke mortality among blacks compared to whites is larger in communities of lower occupational structure. CONCLUSIONS--Consideration of occupational structure and related patterns of economic development is crucial for understanding the distribution of stroke mortality within and between racial groups, as well as for planning effective public health interventions. The larger racial inequalities in communities of lower occupational structure in the south suggest that aspects of the black experience which are conducive to high rates of stroke mortality are exacerbated in those communities. Public health interventions to reduce the racial and social inequalities in stroke mortality should recognise the social context within which nutritional, occupational, medical care, and

Occupational therapy practice in emergency care: Occupational therapists' perspectives.

PubMed

Spang, Lisa; Holmqvist, Kajsa

2015-01-01

Emergency care takes place in a complex work environment that is characterized by critically ill patients, short hospital stays, and a wide variety of different healthcare professionals. Studies of occupational therapists' (OTs) experiences of working within emergency care have shown that they often experience difficulties in explaining the essence of occupational therapy and have to justify their approaches. Much effort has been made in Sweden to help OTs dispel the notion that occupational therapy is difficult to explain, and the aim of this study was to describe how Swedish OTs perceive their work in emergency care. A qualitative descriptive approach was taken, and 14 interviews were conducted with OTs working in emergency care. Qualitative content analysis was used to analyse the data. The overall theme that emerged was "Feeling established through deliberate occupation-based work". The underlying categories showed different strategies used by the OTs to provide occupational therapy in an emergency care context. Deliberate strategies were used to demonstrate the effectiveness of occupational therapy and its approaches to patients and other health care professionals, and this resulted in the OTs feeling both established and needed. Unlike the OTs in previous studies, the Swedish OTs experienced no difficulties in explaining occupational therapy and could make convincing arguments for their interventions. Parallel to their clinical work, the OTs worked with on-going development to find ways to improve their approaches. In summary, these Swedish OTs seem to have been provided with a professional language and the knowledge required to establish themselves in an emergency care setting.

To analyze the cause of misdiagnosis of occupational chronic n-hexane poisoning and to investigate the diagnosis and differential diagnosis of this disease. The clinical data of 16 patients with occupational chronic n-hexane poisoning who had been misdiagnosed with other diseases were collected. The hospital they first visited, cause of misdiagnosis, clinical features, and the misdiagnosis rate among inpatients during the same period were retrospectively analyzed. Sixteen of 62 patients hospitalized during the same period were misdiagnosed at the first visit; 11 cases were in the upper first-class hospitals, and 5 cases in the upper second-class hospitals; 5 cases were misdiagnosed as Green Barry syndrome, 2 cases as motor neuron disease, 2 cases as drug-induced peripheral neuropathy, 3 cases as periodic paralysis, and 4 cases had uncertain diagnosis. Most doctors who work in ordinary hospitals do not know occupational chronic n-hexane poisoning, which is often misdiagnosed as general neuropathies or difficult diseases. The key to correct diagnosis is to know the patient's occupational history and clinical features.

From welfare states to welfare sectors: Explaining sectoral differences in occupational pensions with economic and political power of employees.

PubMed

Wiß, Tobias

2015-12-01

Studies analysing welfare have previously focused on countries as units. In the course of pension cuts and the increasing importance of occupational welfare, our traditional understanding of a homogeneous welfare state is being challenged. In this article, I distinguish between both economic individual power (employee skills) and political collective power (trade unions), and their relation with different occupational pensions. A combined analysis by both factors is not common, where employee skills and power resources are traditionally treated as separate, rival explanations of public welfare. Combining the 'method of difference' with the 'method of agreement', the article first presents the within-country variety of occupational pensions in Germany, Italy, the United Kingdom and Denmark. Occupational pensions in the same economic sectors across countries are then used as the units of analysis in order to illustrate the plausible determinants of economic individual power and political collective power.

Occupational correlates of smoking among urban transit operators: a prospective study.

Workers in blue-collar and service occupations smoke at higher rates than workers in white-collar and professional occupations. Occupational stress may explain some of the occupational class differences in smoking and quitting behavior. The purpose of this study is to investigate the contribution of occupational factors to smoking behavior over a ten year period among a multiethnic cohort of urban transit operators, while accounting for demographic factors and alcohol. The sample consists of 654 San Francisco Municipal Railway (MUNI) transit operators who participated in two occupational health studies and biennial medical examinations during 1983-85 and 1993-95. Workers who had initiated, increased, or maintained their smoking over the ten year period were compared to workers who remained non-smokers. Occupational factors included self-rated frequency of job problems (e.g., difficulties with equipment, passengers, traffic), job burnout (i.e., the emotional exhaustion subscale of the Maslach Burnout Inventory), time needed to unwind after work, and years employed as a transit operator. A series of logistic regression models were developed to estimate the contribution of occupational factors to smoking behavior over time. Approximately 35% of the workers increased, initiated, or maintained their smoking over the ten-year period. Frequency of job problems was significantly associated with likelihood of smoking increase, initiation, or maintenance (OR = 1.30; 95% CI 1.09, 1.55). Black operators were significantly more likely to have smoked over the ten-year period compared to operators in other racial/ethnic groups. Understanding the role of work-related stress vis-à-vis smoking behavior is of critical importance for crafting workplace smoking prevention and cessation interventions that are applicable to blue-collar work settings, and for developing policies that mitigate occupational stress.

Health care employees are often women, a group that has high degrees of sick leave and perhaps problems attaining occupational balance. However, people think differently about their everyday activities and it is therefore important to take their perceptions into account but occupational balance has not yet been measured in health professionals. The aim was to describe occupational balance in three different samples of health professionals in Sweden. A further aim was to investigate whether occupational therapists (OTs) rate their occupational balance differently from other health professionals. Four hundred and eighty-two health professionals, employees in public dentistry, mental health care and OTs, aged 21-70 years participated. The participants' occupational balance was measured using the occupational balance questionnaire (OBQ). The ratings of occupational balance were similar to earlier studies and did not differ significantly between the samples. The OTs' occupational balance was also similar to that of the other health professionals. The similarities in occupational balance indicate the same difficulties in attaining it. The result highlights the possibility that working people face similar difficulties in achieving occupational balance. Further research is warranted about how to attain it.

The occupational environment has been a most fruitful one for investigating the etiology of human cancer. Many recognized human carcinogens are occupational carcinogens. There is a large volume of epidemiologic and experimental data concerning cancer risks in different work environments. It is important to synthesize this information for both scientific and public health purposes. Various organizations and individuals have published lists of occupational carcinogens. However, such lists have been limited by unclear criteria for which recognized carcinogens should be considered occupational carcinogens, and by inconsistent and incomplete information on the occupations and industries in which the carcinogenic substances may be found and on their target sites of cancer. Based largely on the evaluations published by the International Agency for Research on Cancer, and augmented with additional information, the present article represents an attempt to summarize, in tabular form, current knowledge on occupational carcinogens, the occupations and industries in which they are found, and their target organs. We have considered 28 agents as definite occupational carcinogens, 27 agents as probable occupational carcinogens, and 113 agents as possible occupational carcinogens. These tables should be useful for regulatory or preventive purposes and for scientific purposes in research priority setting and in understanding carcinogenesis. PMID:15531427

To explore gender difference of relationship between occupational stress and depressive symptoms. The cross-sectional study was used to investigate 5338 workers in 13 factories and companies, the depressive symptoms were assessed with Epidemiologic Studies Depression Scale (CES-D) and the perceived occupational stress was evaluated by the Chinese version of the Job Content Questionnaire (JCQ) and Effort-Reward Imbalance (ERI) Model Questionnaire. Logistic regression analyses were conducted to estimate the associations between occupational stress and prevalence of depressive symptoms. Prevalence of depressive symptoms was 31.8% for all subjects, 33.8% for males and 27.7% for females, gender difference of prevalence was significant (P < 0.01). Psychological demands, physical demands, job control, effort, overcommitment and negative affectivity scores for males were significantly higher than those for females(P < 0.01 or 0.05), social support, reward and job satisfaction scores for males were significantly lower than those for females (P < 0.01). Psychological demands, physical demands, job control, effort, overcommitment and negative affectivity scores for workers with depressive symptoms were significantly higher than those for workers without depressive symptoms (P < 0.01) but job control, social support, reward, job satisfaction and positive affectivity scores for workers with depressive symptoms were significantly lower than those for without depressive symptoms (P < 0.01). Psychological demands, physical demands, job control, effort, overcommitment and negative affectivity scores for male workers with depressive symptoms were significantly higher than those for female counterparts (P < 0.01), but social support, reward, job satisfaction scores for male workers with depressive symptoms were significantly lower than hose for female workers with depressive symptoms (P < 0.01).

Depression has been reported as common among older rural Chinese adults, who often face limited access to healthcare services and resources. Empirical studies conducted in the West have shown beneficial effects of productive engagement on psychological well-being. However, the mechanisms by which engagement in productive activities leads to and results from improved mental health remain unclear. Utilizing role enhancement and social resource theories, the present study investigated the relationship between productive role occupancy and depression among older Chinese adults in rural areas over 8 years. Using four waves of data from the Well-Being of Elderly in Anhui Province of China study, we employed bivariate latent different score analysis to examine the temporal sequence of productive role occupancy and depression among 1696 older adults. Findings indicated that trajectories of productive role occupancy and depression rose across the four waves. There is evidence for self-feedback effects in productive role occupancy and depression. Depression had a significant effect on subsequent changes in productive role occupancy (β = -0.042, p = 0.000), whereas productive role occupancy had no significant effect on subsequent changes in depression. The mental well-being of participants worsened over time. Engaging in productive activities had no effect on mental health status, and rural older adults with poor mental health were less likely to engage in productive activities over time. Findings suggest that psychological well-being as a personal resource significantly affects how productively Chinese adults age in late life.

The aim of this study was to examine the relationship between occupation and sleep duration, sleepiness, insufficient sleep, and insomnia in day and shift workers (including night work and watches). The study was population-based and cross-sectional, and relied on self-administered questionnaires. It was conducted as part of the 1997-1999 Hordaland Health Study in collaboration with the Norwegian National Health Screening Service. Aged 40-45 years, 7782 participants answered a sleep questionnaire, reporting their occupation and whether or not they were employed in shift work. Our study found differences in sleep duration during the working week between occupational groups; in both shift and day workers. Craft workers, plant operators, and drivers slept less than leaders, and non-personal and personal service workers. Within some occupations (leaders, personal service workers, and plant operators), shift workers slept less than day workers. The mean sleep duration of shift workers was 15 minutes shorter than that of day workers. Rise times, but not bedtimes, were earlier in craft-and construction workers, plant operators, and drivers than in leaders and non-personal and personal service workers, particularly day workers. When adjusted for shift work and working hours - compared to leaders - craft workers, plant operators, and drivers had an increased risk of daytime sleepiness (odds ratio 1.5, 1.8, and 1.8 respectively) and of falling asleep at work (odds ratio 1.6, 2.1 and 2.0 respectively). Shift workers had an increased risk of falling asleep at work and insomnia. Occupation has separate effects on sleep duration and sleep-related problems, independent of the effects of shift work.

Occupation-based intervention in hand injury rehabilitation: Experiences of occupational therapists in Malaysia.

In a previous study consensus was sought from Malaysian occupational therapists of occupation-based intervention (OBI) that was perceived as a means and an end. Occupation as a means refers to occupational and purposeful tasks as a therapeutic agent while occupation as an end refers to occupation as an outcome of intervention. The purpose of this follow-up study was to describe the occupational therapists' experiences of providing OBI in hand injury rehabilitation in Malaysia. Sixteen occupational therapists with more than five years of experience in hand rehabilitation were individually interviewed on their experiences of using OBI in practice. Data were thematically analysed using interpretative phenomenological analysis. Definition of "Occupation as a means", and "Occupation as an end" was broadened after data analysis of interviews to include two new themes: "Rewarding yet challenging" and "Making OBI a reality". Occupational therapists had positive experiences with OBI and perceived that occupation as a means and an end can be merged into a single therapy session when the occupational therapists use an occupation that is therapeutic. Although occupation as a means and as an end have different purposes, when the ultimate goal is to enhance the clients' maximum level of functioning both can be used for successful rehabilitation of hand injuries.

Sex-role patterns, the father's rearing attitude and the child's intellectual and emotional development in different social classes were studied in a randomly selected sample of 58 Swedish unbroken families of a small child. Working class men and women married younger and the women were more often house-wives. Working class men had more often been reared in an "authoritarian" way and more often reared their children in the same way. Upper middle class men had taken a more active part in the care of the child. Working class children scored lower on the intelligence tests, especially the verbal ones and were more often estimated as socially immature.

Facial soft tissue thickness differences among three skeletal classes in Japanese population.

2014-03-01

Facial reconstruction is used in forensic anthropology to recreate the face from unknown human skeletal remains, and to elucidate the antemortem facial appearance. This requires accurate assessment of the skull (age, sex, ancestry, etc.) and thickness data. However, additional information is required to reconstruct the face as the information obtained from the skull is limited. Here, we aimed to examine the information from the skull that is required for accurate facial reconstruction. The human facial profile is classified into 3 shapes: straight, convex, and concave. These facial profiles facilitate recognition of individuals. The skeletal classes used in orthodontics are classified according to these 3 facial types. We have previously reported the differences between Japanese females. In the present study, we applied this classification for facial tissue measurement, compared the differences in tissue depth of each skeletal class for both sexes in the Japanese population, and elucidated the differences between the skeletal classes.

Coffee is one of the most widely consumed beverages in the world, because of its unique sensory properties and physiological properties. Coffee beverages represent a significant source of antioxidants in the consumers' diet and contribute significantly to their daily intake. The aim of this research was to investigate the effect of different roasting degrees on the content of biologically active compounds and antioxidant activity in different quality classes of Arabica coffee. Samples of green Arabica coffee (Rio Minas) of two quality classes from two production batches were used for the research. Roasting was carried out at temperatures of 167, 175 and 171°C. The total phenol content (TPC), total flavonoid content (TFC), flavonol content (FC) and antioxidant activity (DPPH, ABTS) in the coffee extracts was determined. This research shows that TPC was significantly higher (P < 0.05) in green coffee compared to TPC in roasted coffee, and TPC decreases as the roasting temperature increases. TFC and FC were significantly lower (P < 0.05) in green coffee than in roasted coffee. Differences in TPC between the 1st and 2nd classes of Arabica coffee were not significant (P > 0.05), while differences in TFC were significant (P < 0.05) only for green coffee from the second production batch and differences in FC were significant (P < 0.05) for green coffee and for coffee roasted at 175°C. Roasting temperatures have different influences the antioxidant activity (DPPH, ABTS) of coffee and the highest antioxidant activity was determined in coffee roasted at 171°C. An exception was 1st class Arabica coffee roasted at 167°C (ABTS). All samples of 1st class Arabica coffee had higher antioxidant activity (DPPH, ABTS) compared to 2nd class Arabica. This research shows that the bioactive compounds content and antioxidant activity of different quality classes of Arabica coffee are dependent on the degree of roasting. TPC decreases when the roasting temperature increases, while TFC

This study validated the Walk@Work-Application (W@W-App) for measuring occupational sitting and stepping. The W@W-App was installed on the smartphones of office-based employees (n=17; 10 women; 26±3 years). A prescribed 1-hour laboratory protocol plus two continuous hours of occupational free-living activities were performed. Intra-class correlation coefficients (ICC) compared mean differences of sitting time and step count measurements between the W@W-App and criterion measures (ActivPAL3TM and SW200Yamax Digi-Walker). During the protocol, agreement between self-paced walking (ICC=0.85) and active working tasks step counts (ICC=0.80) was good. The smallest median difference was for sitting time (1.5seconds). During free-living conditions, sitting time (ICC=0.99) and stepping (ICC=0.92) showed excellent agreement, with a difference of 0.5minutes and 18 steps respectively. The W@W-App provided valid measures for monitoring occupational sedentary patterns in real life conditions; a key issue for increasing awareness and changing occupational sedentariness.

Little is known about the impact of different marketing strategies on enrollment of online courses for health professionals. The authors compared one aspect of marketing, course titles, for online classes about herbs and dietary supplements (HDS). The authors marketed two titles-one knowledge-oriented, the other behavior-oriented-for each of seven online HDS classes. The two titles were (1) "Introduction to topic" (Knowledge) and (2) "Talking with patients about topic" (Behavior). The seven classes were two general (introduction and safety) and five specialty (women, children, the elderly, depression, and gastrointestinal) topics. The Area Health Education Center in northwest North Carolina marketed the classes. Altogether, 195 clinicians enrolled in an average of 7.6 classes per enrollee (1,487 total). For every class, enrollment was higher for knowledge-oriented than behavior-oriented titled classes (average of 124 versus 89 enrollees per class, P < .01). Enrollment, combining the two general classes, was also significantly higher for general than specialty classes (266 versus 191 enrollees per class, P < .01). Differences in titles and levels of generality significantly impacted enrollment rates in these online classes on an unfamiliar topic. Additional marketing research is needed to inform efforts to enroll clinicians into courses on more familiar topics.

Class, paid employment and family roles: making sense of structural disadvantage, gender and health status.

PubMed

Arber, S

1991-01-01

The British tradition of analysing differences in health has been dominated by class, with women belatedly entering this debate. The American tradition has been dominated by role analysis, with women's health considered primarily in terms of their marital, parental and employment roles, with recent research coming to contradictory conclusions. Research in both traditions has reached an impasse. This paper uses a sample of over 25,000 men and women from the 1985 and 1986 British General Household Survey to show how both traditions need to be reformulated and integrated. The ways in which family roles are associated with women's health status is determined by material circumstances, but the material circumstances cannot be captured by occupational class alone. Participation in the labour market and consumption divisions, in the form of housing tenure, are crucial additional indicators of structural disadvantage. Standardised limiting long-standing illness ratios and multivariate logit analysis confirm that occupational class and paid employment are the most important attributes associated with health status for women and men. Family roles are important for women; women without children and previously married women have particularly poor health status especially those not in paid employment and living in local authority housing.

A comparison of some of the characteristics of patients with occupational and non-occupational asthma.

Occupational asthma is the most frequently diagnosed occupational lung disease reported to the SWORD (Surveillance of Work-related and Occupational Respiratory Disease) scheme. However, diagnosing occupational asthma is not straightforward, and establishing a link with work may be difficult. This study was undertaken to determine the differences between patients with occupational asthma and those with non-occupational asthma which might help in their diagnosis. Information was collected using a self-completed questionnaire. Questionnaires were distributed to 30 subjects aged 18-65 years at each of two clinics--one for patients with occupational asthma and one for those with cryptogenic and environmental asthma. Replies were received from 26 patients with occupational asthma (87%) and 29 patients with non-occupational asthma (97%). The age of onset was significantly higher for those with occupational asthma (42.6 vs 20.7 years). Significantly more subjects with occupational asthma reported improvement on holiday, whereas no significant difference was found in the numbers reporting worsening of symptoms on work days. Those with occupational asthma were less likely to report seasonal variation in symptoms, exacerbation by allergies, pets and stress, or a family history of asthma. Subjects with occupational asthma were more likely to become unemployed (50% vs 3%). Recognition of some of these features in a patient's history may help in the difficult task of differentiating occupational from non-occupational asthma, potentially avoiding the need for exhaustive investigations in some patients. The high prevalence of holiday improvement among subjects with non-occupational asthma suggested that domestic or environmental allergies arising outside the workplace may have been making an important contribution to ongoing symptoms in these subjects.

Gender differences in preferences for coaching as an occupation: the role of self-efficacy, valence, and perceived barriers.

This study investigated gender differences in the role of self-efficacy, occupational valence, valence of coaching, and perceived barriers in preference to coach at the high school, 2-year college, Division III, Division II, and Division I levels. The participants, 191 Big Ten university basketball players (94 men, 97 women), responded to a specially constructed instrument. The genders did not differ in their coaching self-efficacy, preferred occupational valence, and perceived barriers. Relative to men, women perceived greater valence in coaching (p < .001). Women with a female coach perceived greater valence in coaching (p < .05) and expressed less concern with perceived discrimination (p < .05) than those with a male coach. Perceived self-efficacy and preferred occupational valence were differentially related to the desire to coach at various levels. Working Hours most negatively affected the desire to coach at every level (R > .20).

Context: Empathy, teamwork, and lifelong learning are described as key elements of professionalism. The first recipients of their benefits are professionals themselves. Paradoxically, scarce studies have reported association between professionalism and occupational well-being. The main purpose of this study was to characterize the influence that empathy, teamwork, and lifelong learning, play in the occupational well-being of physicians and nurses working in Latin American healthcare institutions. Materials and Methods: The Jefferson Scale of Empathy, the Jefferson Scale of Attitudes toward Physician-Nurse Collaboration, the Jefferson Scale of Physicians Lifelong Learning, and the Scale of Collateral Effects (somatization, exhaustion, and work alienation), were administered to 522 physicians and nurses working in institutions of Mexico, Colombia, Ecuador, and Argentina. Internal reliability was calculated. Gender and discipline were used as explanatory variables in comparison analysis. Two-way analysis of variance was performed to examine differences due to the main effects of the gender, and discipline, and to determine possible combined effects. Correlation analysis was performed to measure associations between collateral effects and age, and between collateral effects and professionalism. Results: A total of 353 (68%) surveys were returned fully completed. Adequate reliability was confirmed in all instruments. No differences were found among countries for collateral effects. Correlation analysis confirmed in physicians an inverse association between empathy and collateral effects (P = -0.16; p < 0.05), and between collateral effects and lifelong learning (P = -0.18; p < 0.01). In nurses, this association was confirmed only for empathy (P = -0.19; p < 0.05). Important differences in the development of professionalism and in its effects on occupational well-being appeared associated to inter-professional collaboration and work roles.

2005-01-01

To evaluate differences in mortality by social class and to determine the impacts of socioeconomic factors on health inequalities in Italy, mortality data from 1981-2001 were analyzed as a function of social class in Turin, controlling for occupational risks, housing conditions, and education. For general and cause-specific mortality, the weight of each socioeconomic indicator was evaluated on population-attributable fraction to social class. Among men, mortality risk was significantly higher in unskilled blue-collar workers (RR = 1.45). Among women, the differences by social class were slighter. Education and economic status mostly explain the mortality differences by social class in men, while economic status showed the highest contribution in women.

Sampling scales define occupancy and underlying occupancy-abundance relationships in animals.

Occupancy-abundance (OA) relationships are a foundational ecological phenomenon and field of study, and occupancy models are increasingly used to track population trends and understand ecological interactions. However, these two fields of ecological inquiry remain largely isolated, despite growing appreciation of the importance of integration. For example, using occupancy models to infer trends in abundance is predicated on positive OA relationships. Many occupancy studies collect data that violate geographical closure assumptions due to the choice of sampling scales and application to mobile organisms, which may change how occupancy and abundance are related. Little research, however, has explored how different occupancy sampling designs affect OA relationships. We develop a conceptual framework for understanding how sampling scales affect the definition of occupancy for mobile organisms, which drives OA relationships. We explore how spatial and temporal sampling scales, and the choice of sampling unit (areal vs. point sampling), affect OA relationships. We develop predictions using simulations, and test them using empirical occupancy data from remote cameras on 11 medium-large mammals. Surprisingly, our simulations demonstrate that when using point sampling, OA relationships are unaffected by spatial sampling grain (i.e., cell size). In contrast, when using areal sampling (e.g., species atlas data), OA relationships are affected by spatial grain. Furthermore, OA relationships are also affected by temporal sampling scales, where the curvature of the OA relationship increases with temporal sampling duration. Our empirical results support these predictions, showing that at any given abundance, the spatial grain of point sampling does not affect occupancy estimates, but longer surveys do increase occupancy estimates. For rare species (low occupancy), estimates of occupancy will quickly increase with longer surveys, even while abundance remains constant. Our results

EBM E-learning: Feasible and Effective for Occupational Physicians in Different Countries.

Although evidence-based medicine (EBM) is a useful method for integrating evidence into the decision-making process of occupational physicians, occupational physicians lack EBM knowledge and skills, and do not have the time to learn the EBM method. In order to enable them to educate themselves at the time and place they prefer, we designed an electronic EBM course. We studied the feasibility and utility of the course as well as its effectiveness in increasing EBM knowledge, skills, and behaviour. Occupational physicians from various countries were included in a within-subjects study. Measurements were conducted on participants' EBM knowledge, skills, behaviour, and determinants of behaviour at baseline, directly after finishing the course and 2 months later (n = 36). The feasibility and utility of the course were evaluated directly after the course (n = 42). The course is applicable as an introductory course on EBM for occupational physicians in various countries. The course is effective in enhancing EBM knowledge and self-efficacy in practising EBM. No significant effect was found on EBM skills, behaviour, and determinants of behaviour. After the course, more occupational physicians use the international journals to solve a case. An electronic introductory EBM course is suitable for occupational physicians. Although it is an effective method for increasing EBM knowledge, it does not seem effective in improving skills and behaviour. We recommend integrating e-learning courses with blended learning, where it can be used side by side with other educational methods that are effective in changing behaviour.

A detailed understanding of the population dynamics of many amphibian species is lacking despite concerns about declining amphibian biodiversity and abundance. This paper explores temporal patterns of occupancy and underlying extinction and colonization dynamics in a regionally imperiled amphibian species, the Northern leopard frog (Lithobates pipiens) in Alberta. Our study contributes to elucidating regional occupancy dynamics at northern latitudes, where climate extremes likely have a profound effect on seasonal occupancy. The primary advantage of our study is its wide geographic scale (60,000 km2) and the use of repeat visual surveys each spring and summer from 2009-2013. We find that occupancy varied more dramatically between seasons than years, with low spring and higher summer occupancy. Between spring and summer, colonization was high and extinction low; inversely, colonization was low and extinction high over the winter. The dynamics of extinction and colonization are complex, making conservation management challenging. Our results reveal that Northern leopard frog occupancy was constant over the last five years and thus there is no evidence of decline or recovery within our study area. Changes to equilibrium occupancy are most sensitive to increasing colonization in the spring or declining extinction in the summer. Therefore, conservation and management efforts should target actions that are likely to increase spring colonization; this could be achieved through translocations or improving the quality or access to breeding habitat. Because summer occupancy is already high, it may be difficult to improve further. Nevertheless, summer extinction could be reduced by predator control, increasing water quality or hydroperiod of wetlands, or increasing the quality or quantity of summer habitat.

Few data are available about the prevalence of occupational exposures to agents which can cause occupational asthma or aggravate preexisting asthma (asthmogens). Using potential occupational exposure data from the National Occupational Exposure Survey (NOES) of 1980-1983, we investigated the number of asthmogen exposures, asthmogen-exposure(s) per production worker, and unprotected occupational asthmogen exposures in different industries and occupations. Data for the entire United States were used to generate estimates of occupational exposure at two selected state and local levels. It was estimated that 7,864,000 workers in the surveyed industries were potentially exposed to one or more occupational asthmogen(s) in the United States. The average number of observed potential exposures per asthmogen-exposed worker was 4.4, and varied from 11.9, in the Water Transportation industry, to 1.2 in Local and Suburban transportation. The largest number of observed potential exposures was recorded in the Apparel and Other Finished Products (garment) industry. This work and further analyses using this approach are expected to contribute to a better understanding of the epidemiology of occupational asthma, and to serve as a guide to target future occupational asthma surveillance efforts.

The class-origin wage gap: heterogeneity in education and variations across market segments.

PubMed

Hällsten, Martin

2013-12-01

This paper uses unique population-level matched employer-employee data on monthly wages to analyse class-origin wage gaps in the Swedish labour market. Education is the primary mediator of class origin advantages in the labour market, but mobility research often only considers the vertical dimension of education. When one uses an unusually detailed measure of education in a horizontal dimension, the wage gap between individuals of advantaged and disadvantaged class origin is found to be substantial (4-5 per cent), yet considerably smaller than when measures are used which only control for level of education and field of study. This is also the case for models with class or occupation as outcome. The class-origin wage gap varies considerably across labour market segments, such as those defined by educational levels, fields of education, industries and occupations in both seemingly unsystematic and conspicuous ways. The gap is small in the public sector, suggesting that bureaucracy may act as a leveller. © London School of Economics and Political Science 2013.

Regular physical activity has positive effects on health at all ages. This study aims to investigate how far physical activity and regular sports engagement, as a more specific type of physical activity, are associated with socioeconomic factors in the middle-aged working population. Data were obtained from 21,699 working men and women aged between 30 and 64 years who participated in the 2009 and 2010 population-based national German Health Update (GEDA) surveys conducted by the Robert Koch Institute. Besides a multi-dimensional index of socioeconomic status (SES), three single dimensions of SES (education, occupation, and income) were used to analyse socioeconomic differences in total physical activity and regular sports engagement. While the prevalence of total physical activity increased with lower SES, the proportion of people with regular sports engagement decreased with lower SES. These associations remained after adjusting for age in men and women. After mutual adjustment of the three single socioeconomic dimensions, physical activity was independently associated with lower education and lower occupational status. Regular sports engagement was observed to be independently associated with higher education, higher occupational status, as well as higher income after mutual adjustment. This study demonstrates significant socioeconomic differences in physical and sports activity in the middle-aged working population. Education, occupation, and income show varying independent associations with physical activity behaviour. Such differences need to be considered when identifying target groups for health-enhancing physical activity interventions.

Participation and occupation in occupational therapy models of practice: A discussion of possibilities and challenges.

Larsson-Lund, Maria; Nyman, Anneli

2017-11-01

Occupation has been the focus in occupational therapy practice to greater or lesser degrees from a historical viewpoint. This evokes a need to discuss whether concepts that are added to our field will enhance or blur our focus on occupation. To explore how the concept of participation in the International Classification of Functioning, Disability and Health (ICF) is related to the concept of occupation by reviewing and comparing its use in three models of practice within occupational therapy. The aim was also to generate discussion on possibilities and challenges concerning the relationship of participation and occupation. The models reviewed were The Model of Human Occupation (MOHO), the Canadian Model of Occupational Performance and Engagement (CMOP-E) and the Occupational Therapy Intervention Process Model (OTIPM). The concept of participation was related to occupation in different ways in these models. Based on the review some challenges and considerations for occupational therapy were generated. Relating the concept of participation from the ICF to the concept of occupation in models of practice can be challenging. At the same time, relating the concepts can be a resource to develop occupational therapy and the understanding of occupational issues in society.

In order to enhance occupational therapy reasoning in clinical practice, different elements such as client-centred approach, evidence-based care and interdisciplinary work should be taken into account, but is a challenge. To describe the development of the digital Hasselt Occupational Performance Profile (H-OPP © ) that enhances occupational therapy reasoning from ICF perspective. A participative qualitative design was used to create the H-OPP © in an iterative way in which occupational therapy lectures, ICF experts, students and occupational therapists in the field were involved. After linking occupational therapy terminology to the ICF, different stages of the H-OPP were identified and elaborated with main features: generating an occupational performance profile based on inventarization of problems and possibilities, formulating an occupational performance diagnosis and enabling to create an intervention plan. In all stages, both the perspectives of the client and the occupational therapist were taken into account. To increase practical use, the tool was further elaborated and digitalized. The H-OPP © is a digital coach that guides and facilitates professional reasoning in (novice) occupational therapists. It augments involvement of the client system. Furthermore, it enhances interdisciplinary communication and evidence-based care.

The workers considered were male private sector employees aged from 16 to 55 years old who worked between 2000 and 2005 as apprentice or blue collar. Two groups were distinguished: immigrants from high migratory pressure Countries (PFPM) and immigrants from high-income Countries (PSA; Italians comprised). The three main nationalities considered were the most relevant in Italy: Moroccans, Albanians, and Romanians. all occupational injuries; severe occupational injuries based on the type of damage. PFPM workers have a higher risk of injury compared to PSA both for total (Relative Risk - RR: 1.45) and severe ones (RR: 1.56), particularly in engineering (RR: 1.64) and trade (RR: 1.61). Moroccans have always the greatest risks (RR: 1.86); Romanians are protected on total injuries (RR: 0.80), but have excess of risk of severe injuries (RR: 1.31). Among young people there aren't differences by Country of birth, but the rate decreases as age increases in PSA, while in PFPM it increases as age increases. In this study, injury risk in regular foreign workers were measured more accurately than official statistics: Whip-Salute database can provide useful information for planning prevention programmes of immigrant work-related injuries.

This study sought to make a qualitative comparison of gender differences regarding environmental barriers to participation in daily occupations from the perspectives of older adults who live alone in Puerto Rico. Twenty-six Hispanic older adults, 70 years or older participated in this study. We used a descriptive qualitative research design in which researchers administered an in-depth interview to each participant. The results elucidated that women were more likely than men to experience restricted participation due to lack of accessibility of the built environment and transportation systems. The findings could help with the development of tailored, occupation-based, preventive interventions that address gender specific environmental barriers and promote greater participation among both women and men. Further research is required to explore whether these environmental barriers to occupational participation remain consistent across living situations, socioeconomic status and ethnicity.

Rooted in the neurodiversity approach, this study provides an overview of the strengths and interests of individuals with Asperger's Syndrome. We interviewed136 individuals with Asperger's Syndrome and 155 neurotypical individuals via an online survey with regards to (a) demography, (b) occupational strengths, (c) general self-efficacy, (d) occupational self-efficacy, and (e) the job interest profile according to Holland. The vocational and educational fields of the individuals with Asperger's in the sample are more diverse than and surpass those classical fields stated in research and biographical literature. The comparison of both groups in cross-tables showed that the indicated strengths differ in several areas (ΦCramer = .02–.47), which means that a specific strength profile can be derived, and this profile goes beyond the clinical view of the diagnostic criteria. Individuals with Asperger's indicate lower self-efficacy, both general and occupational. Furthermore, a high concentration of individuals with Asperger's can be found in the areas I (Investigative) and C (Conventional) of Holland's RIASEC model. PMID:24950060

Since the implementation of the Occupational Safety and Health Act, safety and health in the work environment has seen marked improvement. Although these improvements are laudable, workplace hazards continue to plague the American worker. Understanding the economic burden of fatalities by industry sector is important to setting broad occupational safety and health research priorities. Cost estimates provide additional information about how fatal injuries affect society and hence can improve injury prevention program planning, policy analysis, evaluation, and advocacy. This study estimated the total, mean, and median societal costs by worker and case characteristic in 2003-2006 for the industry sectors identified in the National Institute for Occupational Safety and Health National Occupational Research Agenda (NORA). Analyses were conducted with restricted access to the Bureau of Labor Statistics Census of Fatal Occupational Injuries data. These data exclude military personnel, decedents with unknown age or sex, and fatalities occurring in New York City. Societal costs were estimated using the cost-of-illness approach, which combines direct and indirect costs to yield an overall cost of an fatal occupational injury. During this period, the cost of the 22,197 fatal occupational injuries exceeded $21 billion. The mean and median costs of these fatalities were $960,000 and $944,000 respectively. Total societal costs by NORA sector ranged from a high of $5.8 billion in Services to a low of $530 million in Healthcare and Social Assistance with mean costs ranging from the nearly $800,000 in Agriculture, Forestry, and Fishing to almost $1.1 million in Mining. The societal costs-total, mean, and median costs-of case and worker characteristics for occupational fatal injuries varied within each NORA sector. To have the greatest societal impact, these costs can be used to target resources for public and private sector research by industry. Published by Elsevier Ltd.

2015-01-01

The article presents data on social-psychological factors which cause the occupational stress. The results showed that there is a link between the level of work motivation and the physiological cost of work. We observed a number of peculiarities of occupational stress development caused by psychoemotional tension depending on the class of intensity of intellectual labor; we also studied biological age of the subjects. The speed of ageing of the employees who work under conditions of emotional stress (direct or indirect responsibility for the safety of other people) was found to increase. The study suggested promising directions of occupational stress prevention.

Vitamin D deficiency is prevalent worldwide, but some groups are at greater risk. We aim to evaluate vitamin D levels in different occupations and identify groups vulnerable to vitamin D deficiency. An electronic search conducted in Medline, Embase, the Cochrane Central Register of Controlled Trials, and CINAHL Plus with Full Text generated 2505 hits; 71 peer-reviewed articles fulfilled the inclusion criteria. Occupations investigated included outdoor and indoor workers, shiftworkers, lead/smelter workers, coalminers, and healthcare professionals. We calculated the pooled average metabolite level as mean ± SD; deficiency/insufficiency status was described as % of the total number of subjects in a given category. Compared to outdoor workers, indoor workers had lower 25-hydroxyvitamin D (25-(OH)D) levels (40.6 ± 13.3 vs. 66.7 ± 16.7 nmol/L; p < 0.0001). Mean 25-(OH)D levels (in nmol/L) in shiftworkers, lead/smelter workers and coalminers were 33.8 ± 10.0, 77.8 ± 5.4 and 56.6 ± 28.4, respectively. Vitamin D deficiency (25-(OH)D < 50 nmol/L), was high in shiftworkers (80%) and indoor workers (78%) compared to outdoor workers (48%). Among healthcare professionals, medical residents and healthcare students had the lowest levels of mean 25-(OH)D, 44.0 ± 8.3 nmol/L and 45.2 ± 5.5 nmol/L, respectively. The mean 25-(OH)D level of practising physicians, 55.0 ± 5.8 nmol/L, was significantly different from both medical residents (p < 0.0001) and healthcare students (p < 0.0001). Nurses and other healthcare employees had 25-(OH)D levels of 63.4 ± 4.2 nmol/L and 63.0 ± 11.0 nmol/L, respectively, which differed significantly compared to practising physicians (p = 0.01), medical residents (p < 0.0001) and healthcare students (p < 0.0001). Rates of vitamin D deficiency among healthcare professionals were: healthcare students 72%, medical residents 65%, practising physicians 46%, other healthcare employees 44%, and nurses 43

The Occupational Disease Surveillance System (ODSS) was established in Ontario, Canada by linking a cohort of workers with data created from Workplace Safety and Insurance Board (WSIB) claims to administrative health databases. The aim of this study was to use ODSS to identify high-risk industry and occupation groups for lung cancer in Ontario. Workers in the WSIB lost time claims database were linked to the Ontario Cancer Registry using subjects' health insurance numbers, name, sex, birthdate and death date (if applicable). Several occupations and industries known to be at increased risk were outlined a priori to examine whether ODSS could replicate these associations. Age-adjusted, sex-stratified Cox proportional hazard models compared the risk of lung cancer within one industry/occupation versus all other groups in the cohort. Workers with a lung cancer diagnosis prior to cohort entry were excluded for analysis, leaving 2 187 762 workers for analysis. During the 1983 to 2014 follow-up, 34 661 workers in the cohort were diagnosed with lung cancer. Among expected high-risk industries, elevated risks were observed among workers in quarries/sand pits and construction industries for both sexes, and among males in metal mines, iron foundries, non-metallic mineral products industries and transportation industries. Excess risk was also observed among occupations in drilling/blasting, other mining/quarrying, mineral ore treating, excavating/grading/paving, truck driving, painting, bus driving and construction. This current surveillance system identified several established high-risk groups for lung cancer and could be used for ongoing surveillance of occupational lung cancer in Ontario. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Loh, Siew Yim; Than, Winn; Quek, Kia Fatt

2011-12-01

Chronic pressure at work has debilitating impact on healthcare employers (e.g. reduced productivity, high costs, poor patient care) and on female healthcare employees (e.g. sickness, dysfunction). This paper highlights relationship at work as the key occupational source of work-stress which is organisational in nature. A cross-sectional study (n = 230) was conducted using the Pressure Management Inventory on several female dominated health professions within a large public hospital. Analysis of variance was used to show relationship between sources and outcome of pressure. Linear regressions were used to predict which sources of pressure (IV) was linked to the outcomes of occupational pressure (DV). The number one source of occupational pressure is relationships at work (i.e. with supervisors), and not workload. 'Relationship' is also the key predictor of several negative outcomes of pressure at work. Analysis of variance showed significant differences in two sources of pressures, i.e. Workload (P = 0.04) and Home-work balance (P = 0.03). This paper provides insights into the occupational pressure of women health professionals by highlighting the organisational sources of pressure and the implications for preventing occupational dysfunction secondary to stress at work.

Turpin, Merrill June; Rodger, Sylvia; Hall, Anna R

2012-10-01

An understanding of students' perceptions of occupational therapy on entry is required to recognise how professional socialisation occurs through curriculum. Findings pertain to a qualitative study investigating students' perceptions of occupational therapy upon entry to two occupational therapy programmes in Australia. Students commencing Bachelor of Occupational Therapy and Masters of Occupational Therapy Studies programmes participated in the study (n = 462). A purpose-designed questionnaire was distributed to students in the first lecture of each programme. Preliminary analysis comprised identification of keywords/phrases and coding categories were generated from patterns of keywords. Frequency counts and percentages of keywords/phrases within categories were completed. Students' responses were categorised as 'what' occupational therapists do; 'how' they do it; 'why' they do it; and 'who' they work with. In 'what' occupational therapists do students frequently described 'helping' people. Both undergraduate and graduate entry masters students used the term 'rehabilitation' to describe how occupational therapy is done, with graduate entry students occasionally responding with 'through occupation' and 'modifying the environment'. Students perceived the 'why' of occupational therapy as getting back to 'everyday activities', with some students emphasising returning to 'normal' activities or life. Regarding the 'who' category, students also thought occupational therapists worked with people with an 'injury' or 'disability'. Students entered their occupational therapy programmes with perceptions consistent with the general public's views of occupational therapy. However, graduate entry students exposed to a pre-reading package prior to entry had more advanced occupational therapy concepts than undergraduate students. © 2011 The Authors.

Exposure assessment in different occupational groups at a hospital using Quick Exposure Check (QEC) - a pilot study.

PubMed

Ericsson, Pernilla; Björklund, Martin; Wahlström, Jens

2012-01-01

In order to test the feasibility and sensitivity of the ergonomic exposure assessment tool Quick Exposure Check (QEC), a pilot-study was conducted. The aim was to test QEC in different occupational groups to compare the exposure in the most common work task with the exposure in the work task perceived as the most strenuous for the neck/shoulder region, and to test intra-observer reliability. One experienced ergonomist observed 23 workers. The mean observation time was 45 minutes, waiting time and time for complementary questions included. The exposure scores varied between the different occupational groups as well as between workers within the occupational groups. Eighteen workers rated their most common work task as also being the most strenuous for the neck/shoulder region. For the remaining five workers, the mean exposure score were higher both for the neck and shoulder/arm in the most common work task. Intra-observer reliability shows agreement in 86% of the exposure interactions in the neck and in 71% in the shoulder/arm. QEC seems to fulfill the expectations of being a quick, sensible and practical exposure assessment tool that covers physical risk factors in the neck, upper extremities and low back.

Research on occupational therapy students has often been concerned with quite narrow topics. However, the basic characteristics of this group are yet to be examined in more depth. This study aimed to explore the sociodemographic, education-related, and work-related characteristics of occupational therapy students. A sample of 160 occupational therapy students in Norway participated. Differences between cohorts of students were examined with one-way analyses of variance (ANOVA) for continuous variables and with chi-square tests for categorical variables. The sample had a mean age of 24 years and was predominantly female (79%). More than one -third of the students had one or both parents in an occupation requiring health education, whereas two-thirds of the students had one or both parents in an occupation requiring higher education. At entry, 57% of the participants had occupational therapy as their preferred choice of education and 43% had previous higher education experience. The few significant differences between the study cohorts were negligible. In the education programmes, specific attention may be considered for students with characteristics associated with increased risk of poorer study performance or other problems. This may concern male students and students with no previous higher education experience.

Does Availability of Worksite Supports for Physical Activity Differ by Industry and Occupation?

To explore combinations of worksite supports (WSS) for physical activity (PA) that may assist employees in meeting PA recommendations and to investigate how availability of WSS differs across industries and occupations. Cross-sectional. Several Missouri metropolitan areas. Adults employed >20 h/wk outside the home. Survey utilized existing self-reported measures (eg, presence of WSS for PA) and the International Physical Activity Questionnaire. Logistic regression was conducted for 2 outcome variables: leisure and transportation PA. Independent variables included 16 WSS. Of particular interest were interaction effects between WSS variables. Analyses were stratified by 5 occupation and 7 industry types. Overall, 2013 people completed the survey (46% response rate). Often, availability of 1 WSS did not increase the likelihood of meeting PA recommendations, but several pairs of WSS did. For example, in business occupations, the odds of meeting PA recommendations through transportation PA increased when employees had access to showers and incentives to bike/walk (odds ratio [OR] = 1.6; 95% confidence interval [CI] = 1.16-2.22); showers and maps (OR = 1.25; 1.02-1.55); maps and incentives to bike/walk (OR = 1.48; 1.04-2.12). Various combinations of WSS may increase the likelihood that employees will meet PA recommendations. Many are of low or no cost, including flexible time for exercise and maps of worksite-adjacent walk/bike routes. Findings may be instructive for employers seeking to improve employee health through worksite PA.

2000-09-01

Ninety commercial lamb carcasses were analysed according to the four different fat classes in the light lamb European classification system. Shoulder fat increased 3%, muscle decreased 2% and bone decreased 1% for each class increase. No significant differences were found among fat classes regarding pH, WHC, cooking losses, juiciness, myoglobin content, meat colour measured immediately after cutting (L*, a*, b*), odour intensity or flavour quality. Some differences were found in colour evolution through ageing. Shear force decreased and tenderness and flavour intensity increased with fat class but this effect was only significant in the leanest animals.

2007-01-01

To compare dental caries levels of schoolchildren stratified in different social classes whose domestic water supply had been fluoridated since birth (Dublin) with those living in an area where fluoridated salt was available (Freiburg). A representative, random sample of twelve-year-old children was examined and dental caries was recorded using World Health Organization criteria. A total of 699 twelve-year-old children were examined, 377 were children in Dublin and 322 in Freiburg. In Dublin the mean decayed, missing, and filled permanent teeth (DMFT) was 0.80 and in Freiburg it was 0.69. An examination of the distribution of the DMFT score revealed that its distribution is highly positively skewed. For this reason this study provides summary analyses based on medians and inter-quartile range and nonparametric rank sum tests. In both cities caries levels of children in social class 1 (highest) were considerably lower when compared with the other social classes regardless of the fluoride intervention model used. The caries levels showed a reduced disparity between children in social class 2 (medium) and 3 (lowest) in Dublin compared with those in social class 2 and 3 in Freiburg. The evidence from this study confirmed that water fluoridation has reduced the gap in dental caries experience between medium and lower social classes in Dublin compared with the greater difference in caries experience between the equivalent social classes in Freiburg. The results from this study established the important role of salt fluoridation where water fluoridation is not feasible.

Efficiency of compensatory orthodontic treatment of mild Class III malocclusion with two different bracket systems

2017-01-01

ABSTRACT Objective: The purpose of this study was to assess the efficiency of compensatory orthodontic treatment of patients with mild Class III malocclusion with two preadjusted bracket systems. Method: Fifty-six matched patients consecutively treated for mild Class III malocclusion through compensatory dentoalveolar movements were retrospectively evaluated after analysis of orthodontic records. The sample was divided into two groups according to the brackets used: Group 1 = non-Class III compensated preadjusted brackets, Roth prescription (n = 28); Group 2 = compensated Class III preadjusted brackets, Capelozza III prescription (n = 28). Cephalometric analysis, number of appointments and missed appointments, months using Class III elastics, and bond/band failures were considered. Treatment time, Peer Assessment Rating (PAR) index at the beginning (PAR T1) and end of treatment (PAR T2) were used to calculate treatment efficiency. Comparison was performed using a MANOVA at p< 0.05. Results: Missed appointments, bond or band failures, number of months using the Class III intermaxillary elastics, and cephalometric measurements showed no statistically significant difference (p> 0.05) between groups. Patients treated with Roth brackets had a treatment time 7 months longer (p= 0.01). Significant improvement in the patient’s occlusion (PAR T2-T1) was observed for both groups without difference (p= 0.22). Conclusions: Orthodontic brackets designed for compensation of mild Class III malocclusions appear to be more efficient than non-compensated straight-wire prescription brackets. Treatment time for Class III patients treated with brackets designed for compensation was shorter than with Roth prescription and no difference in the quality of the occlusal outcome was observed. A prospective randomized study is suggested to provide a deeper look into this subject. PMID:29364379

From welfare states to welfare sectors: Explaining sectoral differences in occupational pensions with economic and political power of employees

PubMed Central

Wiß, Tobias

2015-01-01

Studies analysing welfare have previously focused on countries as units. In the course of pension cuts and the increasing importance of occupational welfare, our traditional understanding of a homogeneous welfare state is being challenged. In this article, I distinguish between both economic individual power (employee skills) and political collective power (trade unions), and their relation with different occupational pensions. A combined analysis by both factors is not common, where employee skills and power resources are traditionally treated as separate, rival explanations of public welfare. Combining the ‘method of difference’ with the ‘method of agreement’, the article first presents the within-country variety of occupational pensions in Germany, Italy, the United Kingdom and Denmark. Occupational pensions in the same economic sectors across countries are then used as the units of analysis in order to illustrate the plausible determinants of economic individual power and political collective power.

Age, occupational class and sickness absence during pregnancy: a retrospective analysis study of the Norwegian population registry

PubMed Central

Ariansen, Anja M S

2014-01-01

Objective Western women increasingly delay having children to advance their career, and pregnancy is considered to be riskier among older women. In Norway, this development surprisingly coincides with increased sickness absence among young pregnant women, rather than their older counterparts. This paper tests the hypothesis that young pregnant women have a higher number of sick days because this age group includes a higher proportion of working class women, who are more prone to sickness absence. Design A zero-inflated Poisson regression was conducted on the Norwegian population registry. Participants All pregnant employees giving birth in 2004–2008 were included in the study. A total number of 216 541 pregnancies were observed among 180 483 women. Outcome measure Number of sick days. Results Although the association between age and number of sick days was U-shaped, pregnant women in their early 20s had a higher number of sick days than those in their mid-40s. This was particularly the case for pregnant women with previous births. In this group, 20-year-olds had 12.6 more sick days than 45-year-olds; this age difference was reduced to 6.3 after control for class. Among women undergoing their first pregnancy, 20-year-olds initially had 1.2 more sick days than 45-year-olds, but control for class altered this age difference. After control for class, 45-year-old first-time pregnant women had 2.9 more sick days than 20-year-olds with corresponding characteristics. Conclusions The negative association between age and sickness absence was partly due to younger age groups including more working class women, who were more prone to sickness absence. Young pregnant women's needs for job adjustments should not be underestimated. PMID:24793246

NAG, Anjali; VYAS, Heer; NAG, Pranab

2016-01-01

Workers in the Indian informal sector are engaged with different occupations. These occupations involve varied work related hazards. These occupational hazards are a consequent risk to health. The study aimed to determine occupational health scenario in the Indian Informal sector. One thousand eleven hundred twenty two workers from five different occupations namely weaving (handloom and power loom), construction, transportation, tobacco processing and fish processing were assessed by interviewer administered health questionnaire.

Workers in the Indian informal sector are engaged with different occupations. These occupations involve varied work related hazards. These occupational hazards are a consequent risk to health. The study aimed to determine occupational health scenario in the Indian Informal sector. One thousand eleven hundred twenty two workers from five different occupations namely weaving (handloom and power loom), construction, transportation, tobacco processing and fish processing were assessed by interviewer administered health questionnaire. Workers suffered from musculo-skeletal complaints, respiratory health hazards, eye problems and skin related complaints. There was a high prevalence of self-reported occupational health problems in the selected sectors. The study finds that workers have occupational exposures to multiple hazards. The absence of protective guards aggrevate their health condition. The study attempts to draws an immediate attention on the existing health scenario of the Indian Informal sector.

The authors explored the influence of social class on identity formation in an interview study of 15 lower income students and 15 affluent students from a highly selective liberal arts school and 15 lower income students from a state college. Students ranked occupational goals as 1st in importance to identity and social class as 2nd. The affluent students regarded social class as significantly more important to identity than did the lower income students, were more aware of structural factors contributing to their success, and had higher occupational aspirations. Social class was an area of exploration for half the students, with higher levels of exploration shown by the lower income private school students than by the state college students. Lower income students developed an ideology that rationalized their social class position.

To describe the cardiovascular risk factors in a working population in the Balearic Islands and to examine whether differences by social class vary according to age and gender. A cross-sectional study was carried out in a sample of active workers aged 20-65 years in the Balearic Islands. The participants were included in the study during their annual work health assessment in 2011. The following variables were collected: occupation, social class, age, gender, height, weight, smoking, blood pressure, lipid profile, and glucose levels. Cardiovascular risk was calculated using two different equations (Framingham and REGICOR). Differences by social class were observed for most cardiovascular risk factors. The pattern of these differences differed depending on age group and gender. Differences in obesity by social class increased with age in women but decreased in men. More differences in hypertension by social class were found among women than among men, with differences increasing with age in both genders. Significant differences by social class were found among women in lipid profile, and these differences increased with age, mainly for low levels of high-density lipoprotein-cholesterol. Inequalities in cardiovascular risk factors by social class were higher among women than among men. Some cardiovascular risk factors such as smoking and obesity showed significant inequalities from a very early age. Copyright © 2014 SESPAS. Published by Elsevier Espana. All rights reserved.

Objective: To investigate the changes in psychological state after occupational exposure in the AIDS occupational exposure population and related influencing factors, and to provide baseline data and a basis for related departments to conduct mental health prevention and intervention for personnel with occupational AIDS exposure. Methods: AIDS risk assessment was performed for all personnel with occupational AIDS exposure in 2014 in Nanning, China, and the Symptom Checklist - 90 (SCL - 90) psychological scale was used for psychological state evaluation at 24 hours, 1 week, and 3 months after occupational exposure in all persons who met the research criteria. Results: Most of the persons with occupational AIDS exposure came from secondary and tertiary hospitals (85%) , and nurses accounted for the highest percentage (78.3% ). The age ranged from 21 to 50 years, and the mean age was 31.02 ± 7.92 years. The persons with occupational AIDS exposure aged 20~29 years accounted for the highest percentage (51.6%) , and most persons (76.7%) graduated from junior colleges. Compared with the adult norm, there was significant increases in the total psychological score and the number of positive items after occupational exposure ( P <0.05). The scores of all items at 24 hours were significantly higher than those at the other time points, and the scores of all items gradually decreased over time ( F =227.24, 267.57, and 287.46, P <0.05). Compared with the adult norm, there were significant increases in the factor points at 24 hours and significant reductions in the factor points at 3 months ( P <0.05). Compared with those at 24 hours, the factor scores at 3 months decreased significantly ( P <0.05). Conclusion: Occupational AIDS exposure affects the mental status of related personnel, and the mental status at 24 hours after exposure is poor. Related departments should provide corresponding psychological counseling for the occupational exposure population at different exposure

Acceptability of residential development in a regional landscape: Potential effects on wildlife occupancy patterns

The conversion of natural lands to developed uses may pose the single greatest human threat to global terrestrial biodiversity. Continued human growth and development over the next century will further exacerbate these effects of habitat loss and fragmentation. Natural resource managers are tasked with managing wildlife as a public trust, yet often have little say in land use decisions. Generally speaking, decision makers could benefit from an understanding of what different regulations mean in terms of wildlife distribution. In a previous paper (Bettigole et al., 2013), we surveyed town residents throughout Vermont to measure how respondents feel about a range of development levels within their town boundaries. We estimated the “social carrying capacity for development” – orSKd – for 251 towns in Vermont. SKd provides an estimate of the level of developed land cover classes that town residents deem “acceptable” within their town boundaries. In this paper, we design a framework for linking the town-specific SKd estimates with the wildlife distribution patterns for three wide-ranging mammalian species: American black bear (Ursus americanus), fisher (Martes pennanti), and bobcat (Lynx rufus). We simulated landscape conditions at SKd for each town in Vermont, and then used existing occupancy models for the three target species to spatially map and compare occupancy rates in the baseline year 2000 with occupancy rates at SKd. With nearly 90% of Vermont towns willing to increase developed landcover classes within town boundaries compared to baseline levels, significant state-wide changes in occupancy rates were predicted for all three focal species. Average occupancy rates declined by −15.9% and −3.1% for black bear and bobcats, respectively. Average occupancy rates for fisher increased by 9.0%. This study provides a method for linking development standards within a town with wildlife occurrence. Across towns, the methodology spatially identifies

Short-term memory development: differences in serial position curves between age groups and latent classes.

Koppenol-Gonzalez, Gabriela V; Bouwmeester, Samantha; Vermunt, Jeroen K

2014-10-01

In studies on the development of cognitive processes, children are often grouped based on their ages before analyzing the data. After the analysis, the differences between age groups are interpreted as developmental differences. We argue that this approach is problematic because the variance in cognitive performance within an age group is considered to be measurement error. However, if a part of this variance is systematic, it can provide very useful information about the cognitive processes used by some children of a certain age but not others. In the current study, we presented 210 children aged 5 to 12 years with serial order short-term memory tasks. First we analyze our data according to the approach using age groups, and then we apply latent class analysis to form latent classes of children based on their performance instead of their ages. We display the results of the age groups and the latent classes in terms of serial position curves, and we discuss the differences in results. Our findings show that there are considerable differences in performance between the age groups and the latent classes. We interpret our findings as indicating that the latent class analysis yielded a much more meaningful way of grouping children in terms of cognitive processes than the a priori grouping of children based on their ages.

Enabling international communication among Brazilian occupational therapists: seeking consensus on occupational terminology.

PubMed

Magalhaes, Lilian; Galheigo, Sandra Maria

2010-09-01

The purpose of this study was to examine how key occupational therapy terminologies are used by Brazilian occupational therapists. A nominal group approach combined with a Delphi technique involving 31 Brazilian occupational therapists was applied. A sociolinguistic approach was adopted since it broadens our understanding of the social and cultural determinants of terminology consolidation. Brazilian occupational therapists were found to adopt the term activity more often than human action or doing. Even less often were praxis and occupation applied. No consensus was reached regarding which of the terms is most preferred. While Brazilian occupational therapists have been developing their profession from international standards, it is still embedded in local demands and policies. Additionally, the political context must be considered when building an international dialogue between members of a professional body. Such a dialogue could engage professionals from different countries in meaningful exchanges about their practices. These exchanges may lead to the development of solid professional communities that can contribute meaningfully to social change. Copyright 2010 John Wiley & Sons, Ltd.

Women's perceptions of everyday occupations: outcomes of the Redesigning Daily Occupations (ReDO) programme.

Eklund, Mona; Erlandsson, Lena-Karin

2014-09-01

The aim was to (i) assess the outcomes of the 16-week Redesigning Daily Occupations (ReDO) programme for women on sick leave due to stress-related disorders, in terms of occupational value, satisfaction with everyday occupations, and participation level; (ii) investigate the relationships between those outcomes and return-to-work rate. A total of 42 women receiving ReDO and 42 receiving care as usual (CAU) were included in a matched-control study with measurements before and after the rehabilitation. Seventy-eight participated on both occasions. They completed self-report questionnaires regarding the aforementioned outcomes. Return-to-work data were obtained from the registers of the Social Insurance Offices. Increases in concrete, symbolic, and self-reward values were found in both groups, but no statistically significant difference between the groups was demonstrated. The ReDO group improved more than the CAU group, however, on satisfaction with everyday occupations and participation level. Occupational value, but not satisfaction with everyday occupations, was related to return to work. Everyday occupations were shown to be relevant outcomes after work rehabilitation. They could play an important role in future development of profession-specific evidence of occupational therapy. Further support was obtained for viewing occupational value and satisfaction with everyday occupations as theoretically distinct phenomena.

Inter-generational micro-class mobility during and after socialism: The power, education, autonomy, capital, and horizontal (PEACH) model in Hungary.

PubMed

Lippényi, Zoltán; Gerber, Theodore P

2016-07-01

We propose a theoretical model of how occupational mobility operates differently under socialism than under market regimes. Our model specifies four vertical dimensions of occupational resources-power, education, autonomy, and capital-plus a horizontal dimension consisting of linkages among occupations in the same economic branch. Given the nature of state socialist political-economic institutions, we expect power to exhibit much stronger effects in the socialist mobility regime, while autonomy and capital should play greater stratifying roles after the market transition. Education should have stable effects, and horizontal linkages should diminish in strength with market reforms. We estimate our model's parameters using data from surveys conducted in Hungary during and after the socialist period. We adopt a micro-class approach, though we test it against approaches that use more aggregated class categories. Our model provides a superior fit to other mobility models, and our results confirm our hypotheses about the distinctive features of the state socialist mobility regime. Mobility researchers often look for common patterns characterizing mobility in all industrialized societies. Our findings suggest that national institutions can produce fundamentally distinct patterns of mobility. Copyright © 2016 Elsevier Inc. All rights reserved.

Can people with disabilities gain from education? Similarities and differences between occupational attainment among persons with and without disabilities.

Boman, Tomas; Kjellberg, Anders; Danermark, Berth; Boman, Eva

2014-01-01

More knowledge is needed of occupational attainment of persons with disabilities, i.e., the relationship between their educational level and their profession, and factors of importance for this relationship. To compare occupational attainment among persons with and without a disability. 3396 informants with disabilities and 19,004 non-disabled informants participated (control group) in a survey study by Statistics Sweden.The informants with disabilities were divided into six groups. Occupational attainment did not differ between the disability groups, neither between persons with and without a disability. Follow-up analysis showed that men with disabilities with primary or secondary school had an occupation above their educational level to a significantly larger extent than women with disabilities. This pattern was even clearer in comparison with the control group. Persons without disabilities, with secondary or higher education, were more successful in the labor market than persons with disabilities. Occupational attainment increased with age in both groups. Young women with disabilities who only have primary or secondary education run a higher risk of having a job that is below their educational level than men at the same educational level. This indicates discriminating mechanisms in the society related to gender and ability.

We assessed the relationship between alcohol consumption in young adulthood (ages 18-30 years) and occupational success 15 years later among Blacks and Whites. We analyzed data from the Coronary Artery Risk Development in Young Adults Study on employment status and occupational prestige at year 15 from baseline. The primary predictor was weekly alcohol use at baseline, after stratification by race and adjustment for socioeconomic factors. We detected racial differences in the relationship between alcohol use in early adulthood and employment status at midlife. Blacks who were very heavy drinkers at baseline were more than 4 times as likely as Blacks who were occasional drinkers to be unemployed at year 15 (odds ratio [OR]=4.34; 95% confidence interval [CI]=2.22, 8.47). We found no statistically significant relationship among Whites. Occupational prestige at midlife was negatively related to very heavy drinking, but after adjustment for marital status, active coping, life stress, and educational attainment, this relationship was statistically significant only among Blacks. Heavy drinking during young adulthood was negatively associated with labor market success at midlife, especially among Blacks.

To compare the preferences of occupational therapists, elderly people, and adults with disabilities regarding prioritization criteria for occupational therapy waiting lists in home care. Discrete choice experiment survey. Survey mailed to occupational therapists working in home care and community-dwelling elderly or disabled persons. A sample (N=714) of home-based occupational therapists (n=241), elderly persons from a bank of research participants (n=226), and adults with physical disabilities recruited through community organizations (n=247). Not applicable. The dependent variable was whether the referral scenario was prioritized or not in each question. The results were analyzed through logistic regression using conditional logit models. Prioritization preferences differed between groups (P<.001). Occupational therapists most strongly prioritized people who had a few falls (odds ratio vs no falls, 48.7), whereas elderly people and adults with disabilities most strongly prioritized people who were unable to enter and exit the home (odds ratio vs no difficulty entering and exiting the home, 30.8 for elderly people and 16.8 for persons with disabilities.) CONCLUSIONS: Our results highlight the gap between the priorities of home-based occupational therapists and their target clientele. Although further inquiry is needed to inform priority setting, the findings emphasize the importance of public or patient involvement in decisions on waiting list prioritization.

Gender-related academic and occupational interests and goals.

PubMed

Petersen, Jennifer; Hyde, Janet Shibley

2014-01-01

This chapter reviews the theories and empirical evidence concerning whether gender differences in academic and occupational goals and interests exist, and if so, why those differences may be present. Expectancy-value theory, stereotype threat, sociocultural theory, and the gender similarities hypothesis lay the theoretical framework for this chapter. Following a brief review of these theories, we describe the evidence for gender differences in academic ability and occupational interests and goals, using meta-analytic reviews wherever possible. Although there are few gender differences in academic ability, some gender differences in occupational goals and interests persist, particularly in science and mathematics. These gender differences may be due to parental or cultural expectations, changes in developmental trends, stereotypes and discrimination, or gendered-expectations to achieve work-family balance. Overall, the pathways to adult occupations are complex, involving many factors that affect occupational goals, interests, and self-concept.

Hunter, Eric J.; Titze, Ingo R.

2012-01-01

Purpose This study creates a more concise picture of the vocal demands placed on teachers by comparing occupational voice use with non-occupational voice use. Methods The National Center for Voice and Speech voice dosimetry databank was used to calculate voicing percentage per hour, as well as average dB SPL and F0. Occupational voice use (9am-3 PM, weekdays) and non-occupational voice use (4 PM-10 PM, weekends) were compared (57 teachers, two weeks each). Results Five key findings were uncovered: [1] similar to previous studies, occupational voicing percentage per hour is more than twice that of non-occupational; [2] teachers experienced a wide range of occupational voicing percentages per hour (30±11%/hr); [3] average occupational voice was about 1 dB SPL louder than the non-occupational voice and remained constant throughout the day; [4] occupational voice exhibited an increased pitch and trended upward throughout the day; [5] some apparent gender differences were shown. Conclusions Data regarding voicing percentages, F0 and dB SPL provide critical insight into teachers’ vocal health. Further, because non-occupational voice use is added to an already overloaded voice, it may add key insights into recovery patterns, and should be the focus of future studies. PMID:20689046

[The occupational physicians' responsibilities].

PubMed

Guardavilla, A

2010-01-01

Occupational physicians can commit two kind of crimes: they can violate rules of safety and health at work with no immediate consequences for the employees but anyway creating a potential danger for them, or they can cause, because of their blame, occupational diseases or accidents at work to the employees. In both cases they can be punished. If we want to understand in detail this kind of responsibility, we must read the Supreme Court's judgements (Supreme Court, 19099/2009; 26539/2008; 20220/2006; 17838/2005; 26439/2007; 24290/2005). The numberless innovations introduced in recent years in the body of occupational safety and health laws called for a different reading of the meaning and the content of occupational physicians' functions, requiring them to collaborate, more than in the past, in the assessment of workplace risks. The responsibility of occupational physicians should be seen also in relation to the responsibility of employers and managers (see the link between health surveillance and art. 18 paragraph 1 letter c) of Legislative Decree no. 81/08). In the occupational safety and health context, the employer and his managers must also require (and ensure) occupational physicians to fulfill their obligations and professional duties.

Objective To determine whether current job is a reasonable surrogate for usual job. Methods Data from the 2010 National Health Interview Survey were utilized to determine concordance between current and usual jobs for workers employed within the past year. Concordance was quantitated by kappa values for both simple and detailed industry and occupational groups. Good agreement is considered to be present when kappa values exceed 60. Results Overall kappa values ± standard errors were 74.5 ± 0.5 for simple industry, 72.4 ± 0.5 for detailed industry, 76.3 ± 0.4 for simple occupation, 73.7 ± 0.5 for detailed occupation, and 80.4 ± 0.6 for very broad occupational class. Sixty-five of 73 detailed industry groups and 78 of 81 detailed occupation groups evaluated had good agreement between current and usual jobs. Conclusions Current job can often serve as a reliable surrogate for usual job in epidemiologic studies. PMID:23969506

Comparing the Effects of Different Body Armor Systems on the Occupational Performance of Police Officers.

Policing duties may inherently be dangerous due to stab, blunt trauma and ballistic threats. The addition of individual light armor vests (ILAVs) has been suggested as a means to protect officers. However, the addition of the extra load of the ILAV may affect officer ability to conduct occupational tasks. The purpose of this study was to determine if wearing any of three different ILAVs made by different companies with their preferred materials and designs (ILAV A, 4.68 percent body weight, ILAV B, 4.05 percent body weight, & ILAV C, 3.71 percent body weight) affected occupational task performance when compared to that in normal station wear. A prospective, within-subjects repeated measures design was employed, using a counterbalanced randomization in which each ILAV was worn for an entire day while officers completed a variety of occupationally relevant tasks. These tasks included a victim drag, car exit and 5-meter sprint, step down and marksmanship task. To compare the effects of the ILAVs on these tasks, a multivariate repeated measures analysis of variance (ANOVA) was conducted, with post hoc pairwise comparisons using a Bonferroni adjustment. Results showed that performance in each task did not vary between any of the ILAV or normal station wear conditions. There was less variability in the marksmanship task with ILAV B, however. The results suggest that none of the ILAVs used in this study were heavy enough to significantly affect task performance in the assessed tasks when compared to wearing normal station wear.

The treatment and prevention of the metabolic syndrome (MetS) is currently one of the major challenges in medicine. The impact of working conditions on metabolic risk has not been adequately studied. Our objective was to compare the prevalence of MetS and metabolic risk in two extremely different occupational groups: firefighters and office workers. A total of 143 male subjects (97 firefighters and 46 office workers) from Germany participated in the study. Anthropometric characteristics, metabolic risk parameters as well as laboratory parameters were collected. MetS was diagnosed according to criteria of the International Diabetes Federation. Sedentary occupation showed a significant tendency towards obesity. Abdominal waist circumference was significantly greater in office workers than in firefighters [5.08 CI (1.44-8.71), p = 0.007]. Concerning metabolic risk factors, abnormal HDL, triglycerides, BMI, blood pressure and waist circumference values were more frequently found in office workers than in firefighters. The MetS was detected in almost 33 % of office workers as compared with only 14 % in firefighters (p = 0.015). Regarding MetS in an international comparison, the prevalence of MetS in German office workers was high and in firefighters it was extremely low. Sedentary occupation as an office worker is associated with a high risk of MetS. Both groups need to be made aware of the metabolic risks, and health promoting concepts such as corporate sports activities or education in healthy nutrition need to be implemented to counteract the development of the MetS and cardiovascular risk factors.

Background The study was conducted to investigate the current status of the occupational health and safety management system (OHSMS) in the construction industry and the effect of OHSMS on accident rates. Differences of awareness levels on safety issues among site general managers and occupational health and safety (OHS) managers are identified through surveys. Methods The accident rates for the OHSMS-certified construction companies from 2006 to 2011, when the construction OHSMS became widely available, were analyzed to understand the effect of OHSMS on the work-related injury rates in the construction industry. The Korea Occupational Safety and Health Agency 18001 is the certification to these companies performing OHSMS in South Korea. The questionnaire was created to analyze the differences of OHSMS awareness between site general managers and OHS managers of construction companies. Results The implementation of OHSMS among the top 100 construction companies in South Korea shows that the accident rate decreased by 67% and the fatal accident rate decreased by 10.3% during the period from 2006 to 2011. The survey in this study shows different OHSMS awareness levels between site general managers and OHS managers. The differences were motivation for developing OHSMS, external support needed for implementing OHSMS, problems and effectiveness of implementing OHSMS. Conclusion Both work-related accident and fatal accident rates were found to be significantly reduced by implementing OHSMS in this study. The differences of OHSMS awareness between site general managers and OHS managers were identified through a survey. The effect of these differences on safety and other benefits warrants further research with proper data collection. PMID:24422176

Forty lower class and 20 middle class children, (half boys and half girls) were grouped on the…

A Case-Based Toxicology Module on Agricultural- and Mining-Related Occupational Exposures

PubMed Central

2012-01-01

Objective. To develop and assess a toxicology module to teach pharmacy students about farming- and mining-related occupational exposures in the context of an existing toxicology elective course. Design. A teaching unit that included lectures and case studies was developed to address the unique occupational exposures of patients working in agricultural and mining environments. Upon completion of this 4-hour (2 class periods) module, students were expected to recognize the clinical signs and symptoms associated with these occupational exposures and propose acceptable therapeutic plans. Assessment. After completing the module, students scored significantly higher on a patient case involving suicide resulting from pesticide consumption. Seventy-three percent of the students scored higher than 90% on a 33-item multiple-choice examination. Eighty-two percent of students were able to correctly read a product label to determine the type of pesticide involved in an occupational exposure. Conclusion. Pharmacy students who completed a module on occupation exposure demonstrated competence in distinguishing occupational exposures from each other and from exposure to prescription and nonprescription drugs. This module can be used to educate future pharmacists about occupational health issues, some of which may be more prevalent in a rural setting. PMID:23049108

A Gibbs sampler for Bayesian analysis of site-occupancy data

USGS Publications Warehouse

Dorazio, Robert M.; Rodriguez, Daniel Taylor

1. A Bayesian analysis of site-occupancy data containing covariates of species occurrence and species detection probabilities is usually completed using Markov chain Monte Carlo methods in conjunction with software programs that can implement those methods for any statistical model, not just site-occupancy models. Although these software programs are quite flexible, considerable experience is often required to specify a model and to initialize the Markov chain so that summaries of the posterior distribution can be estimated efficiently and accurately. 2. As an alternative to these programs, we develop a Gibbs sampler for Bayesian analysis of site-occupancy data that include covariates of species occurrence and species detection probabilities. This Gibbs sampler is based on a class of site-occupancy models in which probabilities of species occurrence and detection are specified as probit-regression functions of site- and survey-specific covariate measurements. 3. To illustrate the Gibbs sampler, we analyse site-occupancy data of the blue hawker, Aeshna cyanea (Odonata, Aeshnidae), a common dragonfly species in Switzerland. Our analysis includes a comparison of results based on Bayesian and classical (non-Bayesian) methods of inference. We also provide code (based on the R software program) for conducting Bayesian and classical analyses of site-occupancy data.

World War II Mobilization in Men’s Work Lives: Continuity or Disruption for the Middle Class?1

PubMed Central

Dechter, Aimée R.; Elder, Glen H.

2016-01-01

The labor needs of World War II fueled a growing demand for both military and war industry personnel. This longitudinal study investigates mobilization into these competing activities and their work life effects among men from the middle class. Hazard estimates show significant differences in wartime activities across occupations, apart from other deferment criteria. By war’s end, critical employment, in contrast to military service, is positively associated with supervisory responsibility for younger men and with occupation change. This empoloyment does not predict postwar career advancement up to the 1970s. By comparison, men who were officers had a “pipeline” to advancement after the war, whereas other service men fared worse than nonveterans. PMID:27656001

Occupational risk factors have to be considered in the definition of high-risk lung cancer populations.

The aim of this study was to compute attributable fractions (AF) to occupational factors in an area in North-Eastern France with high lung cancer rates and a past of mining and steel industry. A population-based case-control study among males aged 40-79 was conducted, including confirmed primary lung cancer cases from all hospitals of the study region. Controls were stratified by broad age-classes, district and socioeconomic classes. Detailed occupational and personal risk factors were obtained in face-to-face interviews. Cumulative occupational exposure indices were obtained from the questionnaires. Attributable fractions were computed from multiple unconditional logistic regression models. A total of 246 cases and 531 controls were included. The odds ratios (ORs) adjusted on cumulative smoking and family history of lung cancer increased significantly with the cumulative exposure indices to asbestos, polycyclic aromatic hydrocarbons and crystalline silica, and with exposure to diesel motor exhaust. The AF for occupational factors exceeded 50%, the most important contributor being crystalline silica and asbestos. These AFs are higher than most published figures. This can be because of the highly industrialised area or methods for exposure assessments. Occupational factors are important risk factors and should not be forgotten when defining high-risk lung cancer populations.

A higher socio-economic level is associated with healthier dietary habits. Nevertheless, socio-economic differences in the intake of fat have not consistently been reported in Europe. The objective of our study was to systematically assess differences in total fat (TF) intake and saturated fat (SF) intake across social groups. Representative samples from nine European countries were used to perform a meta-analysis of surveys between 1985-1999, including both published and nonpublished results. Because important heterogeneity was found and the estimates for TF from Spain and Estonia were different from all others, we calculated the differences in intake excluding these two countries. We found a lower TF intake in the highest (versus the lowest) occupational level both for men (difference: -1.1% of total energy intake; 95% CI: -1.3 to -0.8%) and women (difference: -0.9%; 95% CI: -1.2 to -0.6%) when Estonia and Spain were excluded. European surveys indicate that people in the lowest category of occupation consume more fat and SF than people in the highest category.

Occupational exposure limits have traditionally focused on preventing morbidity and mortality arising from inhalation exposures to individual chemical stressors in the workplace. While central to occupational risk assessment, occupational exposure limits have limited application as a refined disease prevention tool because they do not account for all of the complexities of the work and non-occupational environments and are based on varying health endpoints. To be of greater utility, occupational exposure limits and other risk management tools could integrate broader consideration of risks from multiple exposure pathways and routes (aggregate risk) as well as the combined risk from exposure to both chemical and non-chemical stressors, within and beyond the workplace, including the possibility that such exposures may cause interactions or modify the toxic effects observed (cumulative risk). Although still at a rudimentary stage in many cases, a variety of methods and tools have been developed or are being used in allied risk assessment fields to incorporate such considerations in the risk assessment process. These approaches, which are collectively referred to as cumulative risk assessment, have potential to be adapted or modified for occupational scenarios and provide a tangible path forward for occupational risk assessment. Accounting for complex exposures in the workplace and the broader risks faced by the individual also requires a more complete consideration of the composite effects of occupational and non-occupational risk factors to fully assess and manage worker health problems. Barriers to integrating these different factors remain, but new and ongoing community-based and worker health-related initiatives may provide mechanisms for identifying and integrating risk from aggregate exposures and cumulative risks from all relevant sources, be they occupational or non-occupational.

This study aims to examine social class differences in smoking, heavy drinking, unhealthy food habits, physical inactivity and obesity, and work-related psychosocial factors as explanations for these differences. This is done by comparing employee cohorts from Britain, Finland and Japan. Social class differences in health behaviours are found in the two western European countries, but not in Japan. The studied psychosocial factors related to work, work-family interface and social relationships did not explain the found class differences in health behaviours.

Work-life balance/imbalance: the dominance of the middle class and the neglect of the working class.

PubMed

Warren, Tracey

2015-12-01

The paper was stimulated by the relative absence of the working class from work-life debates. The common conclusion from work-life studies is that work-life imbalance is largely a middle-class problem. It is argued here that this classed assertion is a direct outcome of a particular and narrow interpretation of work-life imbalance in which time is seen to be the major cause of difficulty. Labour market time, and too much of it, dominates the conceptualization of work-life and its measurement too. This heavy focus on too much labour market time has rendered largely invisible from dominant work-life discourses the types of imbalance that are more likely to impact the working class. The paper's analysis of large UK data-sets demonstrates a reduction in hours worked by working-class men, more part-time employment in working-class occupations, and a substantial growth in levels of reported financial insecurity amongst the working classes after the 2008-9 recession. It shows too that economic-based work-life imbalance is associated with lower levels of life satisfaction than is temporal imbalance. The paper concludes that the dominant conceptualization of work-life disregards the major work-life challenge experienced by the working class: economic precarity. The work-life balance debate needs to more fully incorporate economic-based work-life imbalance if it is to better represent class inequalities. © London School of Economics and Political Science 2015.

Rural and Urban Differences in Passenger-Vehicle-Occupant Deaths and Seat Belt Use Among Adults - United States, 2014.

Motor-vehicle crashes are a leading cause of death in the United States. Compared with urban residents, rural residents are at an increased risk for death from crashes and are less likely to wear seat belts. These differences have not been well described by levels of rurality. 2014. Data from the Fatality Analysis Reporting System (FARS) and the Behavioral Risk Factor Surveillance System (BRFSS) were used to identify passenger-vehicle-occupant deaths from motor-vehicle crashes and estimate the prevalence of seat belt use. FARS, a census of U.S. motor-vehicle crashes involving one or more deaths, was used to identify passenger-vehicle-occupant deaths among adults aged ≥18 years. Passenger-vehicle occupants were defined as persons driving or riding in passenger cars, light trucks, vans, or sport utility vehicles. Death rates per 100,000 population, age-adjusted to the 2000 U.S. standard population and the proportion of occupants who were unrestrained at the time of the fatal crash, were calculated. BRFSS, an annual, state-based, random-digit-dialed telephone survey of the noninstitutionalized U.S. civilian population aged ≥18 years, was used to estimate prevalence of seat belt use. FARS and BRFSS data were analyzed by a six-level rural-urban designation, based on the U.S. Department of Agriculture 2013 rural-urban continuum codes, and stratified by census region and type of state seat belt enforcement law (primary or secondary). Within each census region, age-adjusted passenger-vehicle-occupant death rates per 100,000 population increased with increasing rurality, from the most urban to the most rural counties: South, 6.8 to 29.2; Midwest, 5.3 to 25.8; West, 3.9 to 40.0; and Northeast, 3.5 to 10.8. (For the Northeast, data for the most rural counties were not reported because of suppression criteria; comparison is for the most urban to the second-most rural counties.) Similarly, the proportion of occupants who were unrestrained at the time of the fatal crash

To investigate the application of risk grading and classification for occupational hazards in risk management for a shipbuilding project. The risk management for this shipbuilding project was performed by a comprehensive application of MES evaluation, quality assessment of occupational health management, and risk grading and classification for occupational hazards, through the methods of occupational health survey, occupational health testing, and occupational health examinations. The results of MES evaluation showed that the risk of occupational hazards in this project was grade 3, which was considered as significant risk; Q value calculated by quality assessment of occupational health management was 0.52, which was considered to be unqualified; the comprehensive evaluation with these two methods showed that the integrated risk rating for this shipbuilding project was class D, and follow- up and rectification were needed with a focus on the improvement in health management. The application of MES evaluation and quality assessment of occupational health management in risk management for occupational hazards can achieve objective and reasonable conclusions and has good applicability.

This is a descriptive study of the frequency and risk of occupant-to-occupant contact injury by crash type and occupant age. It focused on rear impacts because of a recent Senate inquiry. 1994-2013 NASS-CDS data were used to investigate the effects of occupant-to-occupant contact on the risk of serious-to-fatal injury (Abbreviated Injury Scale [AIS] 3+) by crash type and age group. NASS-CDS in-depth cases were analyzed to identify crash circumstances for AIS 3+ occupant-to-occupant contact injury in rear crashes. Serious injury (AIS 3+) due to occupant-to-occupant contact was uncommon. It represented only 0.84% of all AIS 3+ injury for all age groups. The overall risk of AIS 3+ occupant-to-occupant contact injury was 0.042 ± 0.007%. The highest incidence was in side impacts (69.8%) followed by rollovers (22.9%). Occupant-to-occupant contact injury risk was lower in rear impacts than in other crash types, at 0.0078 ± 0.0054%. The highest risk of AIS 3+ injury with occupant-to-occupant was for the <9-year-old age group when compared to other age groups for all crash types. The risk was 0.051 ± 0.026%, representing 2.69% of all AIS 3+ injury in the <9-year-old age group. Only 4.2% of AIS 3+ occupant-to-occupant contact injury occurred to children <9 years old in rear impacts. The corresponding injury risk was lowest in rear impacts, at 0.014 ± 0.014%%, when compared to other crash types. The analysis of in-depth NASS-CDS cases of occupant-to-occupant contact injury in children< 9 years old involved in rear impacts identified very severe collisions in older model vehicles with deformation of the occupant compartment and yielding front seats as main factors for the contact injury. Front seat occupants injuring rear-seated children was not identified in the in-depth NASS-CDS cases. AIS 3+ occupant-to-occupant contact injury occurs primarily in side impacts and rollovers. Most contact injury is to adults (89.4% incidence). Occupant-to-occupant contact injury to

The history and the recent state of occupational medicine in Hungary, and its relation with governmental labor organizations are analyzed. In the past 20 years, large "socialist" factories were replaced by smaller companies employing fewer workers. They have been forced to establish contract with occupational health providers. Many of them offer primary care services, whereas family physicians having a board examination in occupational medicine are allowed to work in this field as well. The market of occupational medicine is less regulated, and ethical rules are not always considered. Undercutting prices is a common practice. The recent system could be improved by some regulations which should be respected. There is no reason to make rough changes establishing a new market for profit oriented insurance companies, and to allow employees and employers to work without specification neglecting international agreements. Occupational medicine should be supervised again by the health authorities instead of economists who have quite different, short-term priorities.

Environmental and Occupational Pesticide Exposure and Human Sperm Parameters: A Systematic Review

PubMed Central

Martenies, Sheena E.; Perry, Melissa J.

2013-01-01

Of continuing concern are the associations between environmental or occupational exposures to pesticides and semen quality parameters. Prior research has indicated that there may be associations between exposure to pesticides of a variety of classes and decreased sperm health. The intent of this review was to summarize the most recent evidence related to pesticide exposures and commonly used semen quality parameters, including concentration, motility and morphology. The recent literature was searched for studies published between January, 2007 and August, 2012 that focused on environmental or occupational pesticide exposures. Included in the review are 17 studies, 15 of which reported significant associations between exposure to pesticides and semen quality indicators. Two studies also investigated the roles genetic polymorphisms may play in the strength or directions of these associations. Specific pesticides targeted for study included dichlorodiphenyltrichloroethane (DDT), hexachlorocyclohexane (HCH), and abamectin. Pyrethroids and organophosphates were analyzed as classes of pesticides rather than as individual compounds, primarily due to the limitations of exposure assessment techniques. Overall, a majority of the studies reported significant associations between pesticide exposure and sperm parameters. A decrease in sperm concentration was the most commonly reported finding among all of the pesticide classes investigated. Decreased motility was also associated with exposures to each of the pesticide classes, although these findings were less frequent across studies. An association between pesticide exposure and sperm morphology was less clear, with only two studies reporting an association. The evidence presented in this review continues to support the hypothesis that exposures to pesticides at environmentally or occupationally relevant levels may be associated with decreased sperm health. Future work in this area should focus on associations between specific

Caesarean section increases the risk of postpartum infection for women and prophylactic antibiotics have been shown to reduce the incidence; however, there are adverse effects. It is important to identify the most effective class of antibiotics to use and those with the least adverse effects. To determine, from the best available evidence, the balance of benefits and harms between different classes of antibiotic given prophylactically to women undergoing caesarean section. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2014) and reference lists of retrieved papers. We included randomised controlled trials comparing different classes of prophylactic antibiotics given to women undergoing caesarean section. We excluded trials that compared drugs with placebo or drugs within a specific class; these are assessed in other Cochrane reviews. Two review authors independently assessed the studies for inclusion, assessed risk of bias and carried out data extraction. We included 35 studies of which 31 provided data on 7697 women. For the main comparison between cephalosporins versus penicillins, there were 30 studies of which 27 provided data on 7299 women. There was a lack of good quality data and important outcomes often included only small numbers of women.For the comparison of a single cephalosporin versus a single penicillin (Comparison 1 subgroup 1), we found no significant difference between these classes of antibiotics for our chosen most important seven outcomes namely: maternal sepsis - there were no women with sepsis in the two studies involving 346 women; maternal endometritis (risk ratio (RR) 1.11, 95% confidence interval (CI) 0.81 to 1.52, nine studies, 3130 women, random effects, moderate quality of the evidence); maternal wound infection (RR 0.83, 95% CI 0.38 to 1.81, nine studies, 1497 women, random effects, low quality of the evidence), maternal urinary tract infection (RR 1.48, 95% CI 0.89 to 2.48, seven studies, 1120

Objectives. We assessed the relationship between alcohol consumption in young adulthood (ages 18–30 years) and occupational success 15 years later among Blacks and Whites. Methods. We analyzed data from the Coronary Artery Risk Development in Young Adults Study on employment status and occupational prestige at year 15 from baseline. The primary predictor was weekly alcohol use at baseline, after stratification by race and adjustment for socioeconomic factors. Results. We detected racial differences in the relationship between alcohol use in early adulthood and employment status at midlife. Blacks who were very heavy drinkers at baseline were more than 4 times as likely as Blacks who were occasional drinkers to be unemployed at year 15 (odds ratio [OR] = 4.34; 95% confidence interval [CI] = 2.22, 8.47). We found no statistically significant relationship among Whites. Occupational prestige at midlife was negatively related to very heavy drinking, but after adjustment for marital status, active coping, life stress, and educational attainment, this relationship was statistically significant only among Blacks. Conclusions. Heavy drinking during young adulthood was negatively associated with labor market success at midlife, especially among Blacks. PMID:19834006

Exploring occupational balance in adults in Sweden.

The aim of this study was to describe the relationship between occupational balance (measured by the occupational balance questionnaire [OBQ]) and self-rated health and life satisfaction. A secondary aim was to explore differences in occupational balance among adults in Sweden. The 153 participants (63% women), recruited using convenience sampling, answered a questionnaire comprising demographic questions, the OBQ, one item about self-rated health, and one about life satisfaction. The OBQ was analysed for correlation with subjective health and life satisfaction. The OBQ and its individual items were also analysed for correlations with age and for differences between men and women and participants living with children younger than 18 years versus not. The OBQ was significantly positively correlated to self-rated health and life satisfaction, supporting the relationship between occupational balance and health. No significant correlation between age and the total OBQ was identified but some differences in occupational balance, related to whether the participant was living with or without children at home, were revealed. The results should be interpreted with caution due to the nature of the sample and data but they can serve as a point of departure for further studies and hypotheses regarding occupational balance in different populations.

Absolute and relative social class dimension inequalities in poor self-reported health and long-term illness were determined for each sex and political tradition. Relative inequalities were assessed by fitting Poisson regression models with robust variance estimators. Absolute and relative health inequalities by social class dimensions are found in the three political traditions, but these differences are more marked in Late democracies and mainly among women. For example the prevalence ratio of poor self-perceived health comparing poorly educated women with highly educated women, was 1.75 (95% CI: 1.39-2.21) in Late democracies and 1.36 (95% CI: 1.21-1.52) in Social democracies. The prevalence differences were 24.2 and 13.7%, respectively. This study is one of the first to show the impact of different political traditions on social class inequalities in health. These results emphasize the need to evaluate the impact of the implementation of public policies.

Objective: Study of the results and the degree on occupational noise-induced deafness in-to the different high frequency hearing threshold weighted value, in order to provide theoretical basis for the re-vision of diagnostic criteria on occupational noise-induced deafness. Methods: A retrospective study was con-ducted to investigate the cases on the diagnosis of occupational noise-induced deafness in Guangdong province hospital for occupational disease prevention and treatment from January 2016 to January 2017. Based on the re-sults of the 3 hearing test for each test interval greater than 3 days in the hospital, the best threshold of each frequency was obtained, and based on the diagnostic criteria of occupational noise deafness in 2007 edition, Chi square test, t test and variance analysis were used to measure SPSS21.0 data, their differences are tested among the means of speech frequency and the high frequency weighted value into different age group, noise ex-posure group, and diagnostic classification between different dimensions. Results: 1. There were totally 168 cases in accordance with the study plan, male 154 cases, female 14 cases, the average age was 41.18 ±6.07 years old. 2. The diagnosis rate was increased into the weighted value of different high frequency than the mean value of pure speech frequency, the weighted 4 kHz frequency increased by 13.69% (χ(2)=9.880, P =0.002) , 6 kHz increased by 15.47% (χ(2)=9.985, P =0.002) and 4 kHz+6 kHz increased by15.47% (χ(2)=9.985, P =0.002) , the difference was statistically significant. The diagnostic rate of different high threshold had no obvious differ-ence between the genders. 3. The age groups were divided into less than or equal to 40years old group (A group) and 40-50 years old group (group B) , there were higher the diagnostic rate between high frequency weighted 4 kHz (A group χ(2)=3.380, P =0.050; B group χ(2)=4.054, P =0.032) , weighted 6 kHz (A group χ(2)=6.362, P =0.012; B group χ(2

Occupational and industrial exposures have been implicated in the etiology of leukemia, yet uncertainty remains regarding potential high risk occupations. We examined the associations between self-reported occupations and hobbies and acute leukemia risk using data from 811 cases and 637 controls participating in a case-control study in the U.S. and Canada. We found that several occupations may increase the risk of acute leukemia, particularly occupations related to petroleum products, rubber, nuclear energy, munitions, plastics, and electronics manufacturing. Differences were noted according to histological type. Other occupations and hobbies were not clearly associated with risk.

During 1990-1992, 282 Chinese residents of Selangor and the Federal Territory, Malaysia with histologically confirmed nasopharyngeal carcinoma (NPC) were interviewed about occupational history, diet, alcohol consumption, and tobacco use, as were an equal number of Malaysian Chinese population controls, pair-matched to cases by age and sex. Exposures to 20 kinds of workplace substances, solar and industrial heat, and cigarette smoke, were analysed by univariate and multivariate methods. Nasopharyngeal carcinoma was associated with occupational exposures to construction, metal and wood dusts; motor fuel and oil; paints and varnishes; certain other chemicals; industrial heat; solar heat from outdoor occupations; certain smokes; cigarette smoking; and childhood exposure to parental smoking. After adjustment for risk from diet and cigarette smoke, only wood dust (OR = 2.36; 95% CI : 1.33- 4.19), and industrial heat (OR = 2.21; 95% CI : 1.12-4.33) remained clearly associated. Wood dust remained statistically significant after further adjustment for social class. No significant crude or adjusted association was found between NPC and formaldehyde (adjusted OR = 0.71; 95% CI : 0.34-1.43). This study supports previous findings that some occupational inhalants are risk factors for NPC. The statistical effect of wood dust remained substantial after adjustment for diet, cigarette smoke, and social class. Intense industrial heat emerged as a previously unreported risk factor, statistically significant even after adjustment for diet and cigarette smoke. No association was found between NPC and formaldehyde.

Occupational and leisure-time physical activity are considered to provide similar health benefits. The authors tested this hypothesis. A representative sample of Danish employees (n=7144, 52% females) reported levels of occupational and leisure-time physical activity in 2005. Long-term sickness absence (LTSA) spells of ≥3 consecutive weeks were retrieved from a social-transfer payment register from 2005 to 2007. 341 men and 620 females experienced a spell of LTSA during the period. Cox analyses adjusted for age, gender, smoking, alcohol, body mass index, chronic disease, social support from immediate superior, emotional demands, social class and occupational or leisure-time physical activity showed a decreased risk for LTSA among workers with moderate (HR 0.85, CI 0.72 to 1.01) and high (HR 0.77, CI 0.62 to 0.95) leisure-time physical activity in reference to those with low leisure-time physical activity. In contrast, an increased risk for LTSA was shown among workers with moderate (HR 1.59, CI 1.35 to 1.88) and high (HR 1.84, CI 1.55 to 2.18) occupational physical activity referencing those with low occupational physical activity. The hypothesis was rejected. In a dose-response manner, occupational physical activity increased the risk for LTSA, while leisure-time physical activity decreased the risk for LTSA. The findings indicate opposing effects of occupational and leisure-time physical activity on global health.

2015-01-01

This study aims, by means of the WorldSID 50th percentile male, to evaluate thoracic loading and injury risk to the near-side occupant due to occupant-to-occupant interaction in combination with loading from an intruding structure. Nine vehicle crash tests were performed with a 50th percentile WorldSID male dummy in the near-side (adjacent to the intruding structure) seat and a THOR or ES2 dummy in the far-side (opposite the intruding structure) seat. The near-side seated WorldSID was equipped with 6 + 6 IR-Traccs (LH and RH) in the thorax/abdomen enabling measurement of bilateral deflection. To differentiate deflection caused by the intrusion, and the deflection caused by the neighboring occupant, time history curves were analyzed. The crash tests were performed with different modern vehicles, equipped with thorax side airbags and inflatable curtains, ranging from a compact car to a large sedan, and in different loading conditions such as car-to-car, barrier, and pole tests. Lateral delta V based on vehicle tunnel acceleration and maximum residual intrusion at occupant position were used as a measurement of crash severity to compare injury measurements. In the 9 vehicle crash tests, thoracic loading, induced by the intruding structure as well as from the far-side occupant, varied due to the size and structural performance of the car as well as the severity of the crash. Peak deflection on the thoracic outboard side occurred during the first 50 ms of the event. Between 70 to 150 ms loading induced by the neighboring occupant occurred and resulted in an inboard-side peak deflection and viscous criterion. In the tests where the target vehicle lateral delta V was below 30 km/h and intrusion less than 200 mm, deflections were low on both the outboard (20-40 mm) and inboard side (10-15 mm). At higher crash severities, delta V 35 km/h and above as well as intrusions larger than 350 mm, the inboard deflections (caused by interaction to the far-side occupant) were of the

The aim of this study was to investigate whether a four-month occupational based health-promoting programme for older persons living in community dwellings could maintain/improve their general health and well-being. Further, the aim was to explore whether the programme facilitated the older persons' occupational adaptation. The study had a quasi-experimental design, with a non-equivalent control group combined with semi-structured interviews. The intervention group comprised 22 participants, and the control group 18. Outcomes were measured using the Short Form 36, Life Satisfaction Index-Z and Meaningful Activity Participation Assessment. Content analysis, based on concepts from the Model of Occupational Adaptation, was used to analyse the interviews. The intervention group showed statistically significant improvements in general health variables such as vitality and mental health, and positive trends for psychological well-being. There were no statistically significant differences between the intervention group and the control group, but the groups were not fully matched. The qualitative analysis based on Occupational Adaptation pointed out social aspects as a compliment to the overall results. Participating in meaningful, challenging activities in different environments stimulates the occupational adaptation process; this is something occupational therapists could use to empower older persons to find their optimal occupational lives.

Untangling the relationships among regional occupancy, species traits, and niche characteristics in stream invertebrates

PubMed Central

Heino, Jani; Grönroos, Mira

2014-01-01

The regional occupancy and local abundance of species are affected by various species traits, but their relative effects are poorly understood. We studied the relationships between species traits and occupancy (i.e., proportion of sites occupied) or abundance (i.e., mean local abundance at occupied sites) of stream invertebrates using small-grained data (i.e., local stream sites) across a large spatial extent (i.e., three drainage basins). We found a significant, yet rather weak, linear relationship between occupancy and abundance. However, occupancy was strongly related to niche position (NP), but it showed a weaker relationship with niche breadth (NB). Abundance was at best weakly related to these explanatory niche-based variables. Biological traits, including feeding modes, habit traits, dispersal modes and body size classes, were generally less important in accounting for variation in occupancy and abundance. Our findings showed that the regional occupancy of stream invertebrate species is mostly related to niche characteristics, in particular, NP. However, the effects of NB on occupancy were affected by the measure itself. We conclude that niche characteristics determine the regional occupancy of species at relatively large spatial extents, suggesting that species distributions are determined by environmental variation among sites.

Objectives To monitor the impact of health and safety provisions and inform future preventive strategies, we investigated trends in mortality from established occupational hazards in England and Wales. Methods We analysed data from death certificates on underlying cause of death and last full-time occupation for 3,688,916 deaths among men aged 20-74 years in England and Wales during 1979-2010 (excluding 1981 when records were incomplete). Proportional mortality ratios (PMRs), standardised for age and social class, were calculated for occupations at risk of specified hazards. Observed and expected numbers of deaths for each hazard were summed across occupations, and the differences summarised as average annual excesses. Results Excess mortality declined substantially for most hazards. For example, the annual excess of deaths from chronic bronchitis and emphysema fell from 170.7 during 1979-90 to 36.0 in 2001-10, and that for deaths from injury and poisoning from 237.0 to 87.5. In many cases the improvements were associated with falling PMRs (suggesting safer working practices), but they also reflected reductions in the numbers of men employed in more hazardous jobs, and declining mortality from some diseases across the whole population. Notable exceptions to the general improvement were diseases caused by asbestos, especially in some construction trades and sinonasal cancer in woodworkers. Conclusions The highest priority for future prevention of work-related fatalities is the minority of occupational disorders for which excess mortality remains static or is increasing, in particular asbestos-related disease among certain occupations in the construction industry and sinonasal cancer in woodworkers.

We examined characteristics of employees in six occupational categories in small manufacturing businesses (20-150 employees). We analyzed survey data from 47 businesses (n = 2577 employees; 86% response rate) and examined relationships between job type and sociodemographic, health, and organizational support characteristics. Analyses were adjusted for age and sex, and company as a random effect. Smoking rates were highest for production workers (33%), production managers (27%), and support staff (28%) and lowest for managers (11%) (P <0.001). Job stress was higher for production workers and support staff than managers (P < 0.0001). Managers perceived social capital (P<0.001), safety climate (P < 0.0001) and support for smoking cessation (P < 0.001) higher than production managers, production workers, and support staff. Differences in characteristics by occupation call for integrated interventions that target working class employees, leverage the influence of production managers, and enhance organizational support.

Social space, social class and Bourdieu: health inequalities in British Columbia, Canada.

2007-03-01

This article adopts Pierre Bourdieu's cultural-structuralist approach to conceptualizing and identifying social classes in social space and seeks to identify health effects of class in one Canadian province. Utilizing data from an original questionnaire survey of randomly selected adults from 25 communities in British Columbia, social (class) groupings defined by cultural tastes and dispositions, lifestyle practices, social background, educational capital, economic capital, social capital and occupational categories are presented in visual mappings of social space constructed by use of exploratory multiple correspondence analysis techniques. Indicators of physical and mental health are then situated within this social space, enabling speculations pertaining to health effects of social class in British Columbia.

Sleights of Hand: South Africa's Gold Mines and Occupational Disease.

McCulloch, Jock

2016-02-01

South Africa's gold mines were the first to compensate silicosis and tuberculosis as occupational diseases. They were also the first mines to introduce a state-sanctioned regime of medical surveillance. Despite those innovations, the major mining houses are currently facing class actions by former miners with occupational lung disease. The obvious reason for this medical and legislative failure is to be found in the economic fabric of South Africa's gold industry. In this article, I will argue that it is also found in the system of mine medicine, which was designed to hide rather than reveal the actual disease rates. © The Author(s) 2016.

To study the influence of occupational pesticide use on Parkinson's disease (PD) in a population with information on various occupational, residential, and household sources of pesticide exposure. In a population-based case control study in Central California, we used structured interviews to collect occupational history details including pesticide use in jobs, duration of use, product names, and personal protective equipment use from 360 PD cases and 827 controls. We linked reported products to California's pesticide product label database and identified pesticide active ingredients and occupational use by chemical class including fungicides, insecticides, and herbicides. Employing unconditional logistic regression, we estimated odds ratios and 95% confidence intervals for PD and occupational pesticide use. Ever occupational use of carbamates increased risk of PD by 455%, while organophosphorus (OP) and organochlorine (OC) pesticide use doubled risk. PD risk increased 110-211% with ever occupational use of fungicides, herbicides, and insecticides. Using any pesticide occupationally for >10years doubled the risk of PD compared with no occupational pesticide use. Surprisingly, we estimated higher risks among those reporting use of personal protective equipment (PPE). Our findings provide additional evidence that occupational pesticide exposures increase PD risk. This was the case even after controlling for other sources of pesticide exposure. Specifically, risk increased with occupational use of carbamates, OPs, and OCs, as well as of fungicides, herbicides, or insecticides. Interestingly, some types of PPE use may not provide adequate protection during pesticide applications. Copyright © 2017 Elsevier Ltd. All rights reserved.

Social class is not often discussed or examined in-depth in couple and family therapy research and literature even though social class shapes familial relationships and is considered an important variable in marital satisfaction. In this qualitative study, we explored the perceptions of eight couples who made lasting commitments across class lines by asking them about the impact of their social class backgrounds on their relationships. Three categories of themes emerged including: (a) differences and similarities in values and attitudes toward education, work, money, and class awareness/classism, (b) relationship issues involving families of origin, friends, and class-based couple conflict, and (c) differences in economic resources, social capital and privileges/opportunities.

Occupancy models to study wildlife

USGS Publications Warehouse

Bailey, Larissa; Adams, Michael John

2005-01-01

Many wildlife studies seek to understand changes or differences in the proportion of sites occupied by a species of interest. These studies are hampered by imperfect detection of these species, which can result in some sites appearing to be unoccupied that are actually occupied. Occupancy models solve this problem and produce unbiased estimates of occupancy and related parameters. Required data (detection/non-detection information) are relatively simple and inexpensive to collect. Software is available free of charge to aid investigators in occupancy estimation.

Occupational differences in job strain and physiological stress: female nurses and school teachers in Hawaii.

The two objectives are to test the hypothesis that women in a profession with low decision latitude will have greater catecholamine excretion and higher blood pressure than women in a profession with greater decision latitude, and to assess the influence of ethnicity on the occupational comparison. Premenopausal women who were either full-time teachers in public schools (teachers; N = 92) or nurses or nurse's aides (nurses; N = 55) in East Hawaii who were not currently taking antihypertensive medication had ambulatory blood pressure (BP) and urinary catecholamine excretion measured over an approximate 4-hour period at work and home and over an approximate 8-hour period overnight. The women also filled out the Job Content Questionnaire (JCQ). The nurses had significantly lower scores on the "decision latitude" subscale of the JCQ. After controlling for the effects of ethnicity, age, body mass index, JCQ subscale scores, smoking habits, and menopausal status in regression analyses, the nurses also had significantly higher mean systolic and diastolic BP both in work and home settings and higher mean rates of both norepinephrine and epinephrine excretion in all daily settings (p < .05). There were no significant ethnic differences in scores on the JCQ subscales, but Asian-Americans had significantly higher systolic BP in all daily settings and higher diastolic BP overnight (p < .05) than Euro-Americans. These results suggest that among professional women, physiological stress responses are significantly greater when occupation-related decision latitude is low (nurses) than when it is high (teachers). The physiological response to stress is carried over into the home and overnight settings when occupation-related decision latitude is low (nurses). Individual scores on the JCQ were not significantly related to physiological measures in this study, however. Inclusion of contrasting occupations may be necessary to properly evaluate the relationships between individually

Patterns of daily occupations (PDO) and occupational balance (OB) are recurring phenomena in the literature. Both are related with health and well-being, which makes them central in occupational therapy practice and occupational science. The aim was to review how PDO and OB are described in the literature, to propose a view of how the two constructs may be linked, and elaborate on how such a view may benefit occupational science and occupational therapy. The literature was analysed by latent and manifest content analysis and comparative analysis. The findings were summarized in a model, framing PDO as the more objective and OB as the more subjective result from an interaction between personal preferences and environmental influences. The proposed model does not assume a cause-effect relationship between the targeted constructs, rather a mutual influence and a joint reaction to influencing factors. Indicators of PDO and OB were identified, as well as tools for assessing PDO and OB. The authors propose that discerning PDO and OB as separate but interacting phenomena may be useful in developing a theoretical discourse in occupational science and enhancing occupational therapy practice. Although the scope of this study was limited, the proposed view may hopefully inspire further scrutiny of constructs.

Ethical tensions arise daily in health care practice and are frequently related to health care system structures or policies. Collective case study methodology was adopted to examine ethical tensions reported by occupational therapists practicing in different settings in Southwestern Ontario, Canada. Inductive analysis involving multiple layers of coding was conducted. This article focuses on tensions related to systemic constraints. Participants reported ethical tensions related to balancing client priorities with those of health care services. Four themes related to systemic constraints were identified including imposed practices, ineffective processes, resource limitations, and lack of services. Therapists' aims could be seen to align with an "ethic of care" and were seen to be in tension in light of systemic constraints. The findings raise issues related to occupational justice, particularly related to occupational alienation in occupational therapy practice, and open conversations related to neoliberalist health care agendas. © The Author(s) 2016.

Objectives. We examined the association between US workers’ access to paid sick leave and the incidence of nonfatal occupational injuries from the employer’s perspective. We also examined this association in different industries and occupations. Methods. We developed a theoretical framework to examine the business value of offering paid sick leave. Data from the National Health Interview Survey were used to test the hypothesis that offering paid sick leave is associated with a reduced incidence of occupational injuries. We used data on approximately 38 000 working adults to estimate a multivariate model. Results. With all other variables held constant, workers with access to paid sick leave were 28% (95% confidence interval = 0.52, 0.99) less likely than workers without access to paid sick leave to be injured. The association between the availability of paid sick leave and the incidence of occupational injuries varied across sectors and occupations, with the greatest differences occurring in high-risk sectors and occupations. Conclusions. Our findings suggest that, similar to other investments in worker safety and health, introducing or expanding paid sick leave programs might help businesses reduce the incidence of nonfatal occupational injuries, particularly in high-risk sectors and occupations.

2017-01-01

Problem/Condition Motor-vehicle crashes are a leading cause of death in the United States. Compared with urban residents, rural residents are at an increased risk for death from crashes and are less likely to wear seat belts. These differences have not been well described by levels of rurality. Reporting Period 2014. Description of Systems Data from the Fatality Analysis Reporting System (FARS) and the Behavioral Risk Factor Surveillance System (BRFSS) were used to identify passenger-vehicle–occupant deaths from motor-vehicle crashes and estimate the prevalence of seat belt use. FARS, a census of U.S. motor-vehicle crashes involving one or more deaths, was used to identify passenger-vehicle–occupant deaths among adults aged ≥18 years. Passenger-vehicle occupants were defined as persons driving or riding in passenger cars, light trucks, vans, or sport utility vehicles. Death rates per 100,000 population, age-adjusted to the 2000 U.S. standard population and the proportion of occupants who were unrestrained at the time of the fatal crash, were calculated. BRFSS, an annual, state-based, random-digit–dialed telephone survey of the noninstitutionalized U.S. civilian population aged ≥18 years, was used to estimate prevalence of seat belt use. FARS and BRFSS data were analyzed by a six-level rural-urban designation, based on the U.S. Department of Agriculture 2013 rural-urban continuum codes, and stratified by census region and type of state seat belt enforcement law (primary or secondary). Results Within each census region, age-adjusted passenger-vehicle–occupant death rates per 100,000 population increased with increasing rurality, from the most urban to the most rural counties: South, 6.8 to 29.2; Midwest, 5.3 to 25.8; West, 3.9 to 40.0; and Northeast, 3.5 to 10.8. (For the Northeast, data for the most rural counties were not reported because of suppression criteria; comparison is for the most urban to the second-most rural counties.) Similarly, the

Work fulfills personal values, perhaps differently for males and females. Explored here was the role values play in shaping occupational interests. Study 1 examined children's, adolescents', and adults' (N = 313) occupational values (regarding money, power, family, altruism), occupational interests, and perceptions of values afforded by traditionally masculine and feminine occupations. Results revealed sex differences in occupational values and interests. Furthermore, participants' values predicted their own interests in culturally masculine and feminine occupations. Study 2 used novel jobs and experimentally manipulated prototypical sex of worker and value affordances to disentangle their effects on occupational interests. At all ages, participants' (N = 240) occupational interests were affected by the depicted sex of the workers and by the stated value affordances of the jobs.

We used a population-based sample of 403 Parkinson's disease cases and 405 controls to examine risks by occupation. Results were compared to a previous clinic-based analysis. With censoring of jobs held within 10 years of diagnosis, the following had significantly or strongly increased risks: social science, law and library jobs (OR = 1.8); farming and horticulture jobs (OR = 2.0); gas station jobs (OR = 2.6); and welders (OR = 3.0). The following had significantly decreased risks: management and administration jobs (OR = 0.70); and other health care jobs (OR = 0.44). These results were consistent with other findings for social science and farming occupations. Risks for teaching, medicine and health occupations were not elevated, unlike our previous clinic-based study. This underscores the value of population-based over clinic-based samples. Occupational studies may be particularly susceptible to referral bias because social networks may spread preferentially via jobs. © 2013 Wiley Periodicals, Inc.

Amyotrophic lateral sclerosis (ALS) and Parkinson's disease, both progressive neurodegenerative diseases, affect >1 million Americans (1,2). Consistently reported risk factors for ALS include increasing age, male sex, and cigarette smoking (1); risk factors for Parkinson's disease include increasing age, male sex, and pesticide exposure, whereas cigarette smoking and caffeine consumption are inversely associated (2). Relative to cancer or respiratory diseases, the role of occupation in neurologic diseases is much less studied and less well understood (3). CDC evaluated associations between usual occupation and ALS and Parkinson's disease mortality using data from CDC's National Institute for Occupational Safety and Health (NIOSH) National Occupational Mortality Surveillance (NOMS), a population-based surveillance system that includes approximately 12.1 million deaths from 30 U.S. states.* Associations were estimated using proportionate mortality ratios (PMRs), standardizing indirectly by age, sex, race, and calendar year to the standard population of all NOMS deaths with occupation information. Occupations associated with higher socioeconomic status (SES) had elevated ALS and Parkinson's disease mortality. The shifts in the U.S. workforce toward older ages and higher SES occupations † highlight the importance of understanding this finding, which will require studies with designs that provide evidence for causality, detailed exposure assessment, and adjustment for additional potential confounders.

The aim of the present study was to investigate the personal variability in occupational exposure to NO(2), as a marker of exposure to diesel exhaust, and to compare a statistical method of grouping workers in homogenous groups with a grouping performed by a qualified occupational hygienist. Forty-seven workers exposed to motor exhaust in their occupation were included. Personal measurements of NO(2) were performed with diffusive samplers over three full working shifts. The results from the measurements were analysed with a linear mixed effects model, taking both between and within-worker variability into consideration. The workers were divided into occupational groups in different ways in order to find a categorization, with maximal homogeneity in exposure in each group. We used (B)R(0.95) as an estimator of the between-worker variability. To study the effect of the divisions on the fit of the statistical model, we used the Akaike Information Criterion. The geometric mean for NO(2) for all 47 workers was 69 μg/m(3) and the between-worker variability (B)R(0.95) was 23.8. In six successive steps, the 47 workers were divided into up to eight groups, based on observed job characteristics. In the final grouping, seven groups were included with geometric means ranging from 32 μg/m(3) for outdoor workers, to 316 μg/m(3) for the most exposed group (tunnel construction workers). The (B)R(0.95) varied between 2.4 and 6.3. The within-worker variability (W)R(0.95) for the last division differed in the groups from 2.0 to 7.9. The Akaike Information Criterion decreased from 246, if all persons were included in one group, to 174 for the final grouping. The average level of NO(2) varied about 10 times between the different occupational groups, with the highest level for tunnel construction workers (316 μg/m(3)) and lowest for outdoor workers (32 μg/m(3)). For four of the seven groups the between-worker variability was higher than the within-worker variability. Copyright �

Self-rated health can be influenced by several characteristics of the social environment. The aim of this study was to evaluate the relationship between self-rated health and self-assessed social class in Slovenian adult population. The study was based on the Countrywide Integrated Non-communicable Diseases Intervention Health Monitor database. During 2004, 8,741/15,297 (57.1%) participants aged 25-64 years returned posted self-administered questionnaire. Logistic regression was used to determine unadjusted and adjusted estimates of association between poor self-rated health and self-assessed social class. Poor self-rated health was reported by 9.6% of participants with a decrease from lower to upper-middle/upper self-assessed social class (35.9 vs. 3.7%). Logistic regression showed significant association between self-rated health and all self-assessed social classes. In an adjusted model, poor self-rated health remained associated with self-assessed social class (odds ratio for lower vs. upper-middle/upper self-assessed social class 4.23, 95% confidence interval 2.46-7.25; P < 0.001). Our study confirmed differences in the prevalence of poor self-rated health across self-assessed social classes. Participants from lower self-assessed social class reported poor self-rated health most often and should comprise the focus of multisectoral interventions.

We clarified the role of cooperation of nursing personnel who work in day care services, to precede our examination of inter-occupational cooperation. The study results revealed that there were four cooperation levels. Subjects for the cooperation included:"difficulty in sharing information,"difficulty in understanding the whole picture,"difficulty in finding directions, "and"difficulty in dealing with emergency cases."The purpose of this study was to clarify the inter-occupational cooperation levels in a day care service and its subjects. We also conducted semi-structured interviews with 13 persons of differing occupations(other than nurses), and who worked in day-care services in A prefecture. As a result, it was revealed that there were three inter-occupational cooperation levels and its subjects included:"difficulty in sharing information" (which was answered the same as the nurses),"difficulty in sharing goals"(which were different among individual occupations), "lack of consistency in care,"necessity of learning because of insufficient knowledge,"and"hesitation to notify."

Using the 1957-2011 data from 3,682 White non-Hispanic women (297 incident breast cancer cases) in the Wisconsin Longitudinal Study, United States, we explore the effect of occupation in 1975 (at age 36) on breast cancer incidence up to age 72. Our study is motivated by the paradoxical association between higher-status occupations and elevated breast cancer risk, which presents a challenge to the consistent health advantage of higher social class. We found that women in professional occupations had 72%-122% and women in managerial occupations had 57%-89% higher risk of a breast cancer diagnosis than housewives and women in lower-status occupations. We explored an estrogen-related pathway (reproductive history, health behaviors, and life-course estrogen cycle) as well as a social stress pathway (occupational experiences) as potential explanations for the effect of higher-status occupations. The elevated risk of breast cancer among professional women was partly explained by estrogen-related variables but remained large and statistically significant. The association between managerial occupations and breast cancer incidence was fully explained by job authority defined as control over others’ work. Exercising job authority was related to higher breast cancer risk (HR = 1.57, 95% CI: 1.12, 2.18), especially with longer duration of holding the professional/managerial job. We suggest that the assertion of job authority by women in the 1970s involved stressful interpersonal experiences that may have promoted breast cancer development via prolonged dysregulation of the glucocorticoid system and exposure of the breast tissue to adverse effects of chronically elevated cortisol. Our study emphasizes complex biosocial pathways through which women’s gendered occupational experiences become embodied and drive forward physiological repercussions. PMID:23726216

Associations Between Marijuana Use Trajectories and Educational and Occupational Success in Young Adulthood.

2018-04-28

Adolescence and young adulthood is a critical stage when the economic foundations for life-long health are established. To date, there is little consensus as to whether marijuana use is associated with poor educational and occupational success in adulthood. We investigated associations between trajectories of marijuana use from ages 15 to 28 and multiple indicators of economic well-being in young adulthood including achievement levels (i.e., educational attainment and occupational prestige), work characteristics (i.e., full vs part-time employment, hours worked, annual income), financial strain (i.e., debt, trouble paying for necessities, delaying medical attention), and perceived workplace stress. Data were from the Victoria Healthy Youth Survey, a 10-year prospective study of a randomly recruited community sample of 662 youth (48% male; M age  = 15.5), followed biennially for six assessments. Models adjusted for baseline age, sex, SES, high school grades, heavy drinking, smoking, and internalizing and oppositional defiant disorder symptoms. Chronic users (our highest risk class) reported lower levels of educational attainment, lower occupational prestige, lower income, greater debt, and more difficulty paying for medical necessities in young adulthood compared to abstainers. Similarly, increasers also reported lower educational attainment, occupational prestige, and income. Decreasers, who had high early use but quit over time, showed resilience in economic well-being, performing similar to abstainers. Groups did not differ on employment status or perceived workplace stress. The findings indicate that early onset and persistent high or increasingly frequent use of marijuana in the transition from adolescent to young adulthood is associated with risks for achieving educational and occupational success, and subsequently health, in young adulthood.

2006-12-01

The aims of this study were to describe which self-care, productivity, and leisure occupations individuals with multiple sclerosis (MS) perceive as difficult to perform on admission to rehabilitation and the individuals' own perception of the importance of, performance of, and satisfaction with these occupations. Whether the reported self-care, productivity, and leisure occupations were related to sex, age, disease severity, and living arrangements was also investigated. Forty-seven men and women (mean age 49.4 years) were assessed with the Canadian Occupational Performance Measure (COPM) on admission to rehabilitation. The individuals reported 366 occupations (median 8, range 3-15), which were categorized as self-care (51%), productivity (30%), and leisure (19%). Three COPM subcategories--household management (26%), personal care (21%), and functional mobility (20%)--accounted for two-thirds of the reported occupations. All prioritized occupations (n = 238; (median 5, range 2-7) had high ratings for importance and the ratings for performance and satisfaction were generally low. Men reported significantly more occupations related to self-care than women, but no significant difference between the sexes could be found for productivity and leisure. No significant differences between the occupational areas were found when age, disease severity, or/and living arrangements were included in the analysis. In conclusion, individuals with MS perceive difficulties with occupations related to all aspects of daily life. This underscores the need to use assessment tools that capture the complexity of daily occupations.

2015-01-01

Objectives We examined characteristics of employees in six occupational categories in small, manufacturing businesses (20–150 employees). Methods We analyzed survey data from 47 businesses (n=2577 employees; 86% response rate) and examined relationships between job type and socio-demographic, health, and organizational support characteristics. Analyses were adjusted for age and gender, and company as a random effect. Results Smoking rates were highest for production workers (33%), production managers (27%), and support staff (28%) and lowest for managers (11%) (p<.001). Job stress was higher for production workers and support staff than managers (p<0.0001). Managers perceived social capital (p<0.001), safety climate (p<0.0001) and support for smoking cessation (p<0.001) higher than production managers, production workers, and support staff. Conclusion Differences in characteristics by occupation call for integrated interventions that target working class employees, leverage the influence of production managers, and enhance organizational support.

Khamitova, R Ia; Loskutov, D V

2012-01-01

The paper provides the results of assessment of prior and posterior occupational risks and those of questionnaire analysis in foundry shop workers from machinery enterprises. According to the data of attestation of job places, the working conditions of major foundry occupations were ascertained to correspond to class 3, grades 1 to 3. The prior risk for occupational respiratory diseases (RD) was defined as moderate whereas the posterior risk was high. According to the results of a questionnaire survey, more than half of the workers sought medical advice for bronchopulmonary pathology. Determination of whether there is, in terms of the etiological share, a cause-and-effect relationship between RDs and working conditions has shown that the occupation was highly responsible, which suggests that harmful industrial factors make a considerable contribution to the development of RDs in the workers of the enterprises under study.

Differences in the dynamics of serotonin reuptake transporter occupancy may explain superior clinical efficacy of escitalopram versus citalopram.

Escitalopram the S-enantiomer of the racemate citalopram, is clinically more effective than citalopram in the treatment of major depressive disorder. However, the precise mechanism by which escitalopram achieves superiority over citalopram is yet to be determined. It has been hypothesized that the therapeutically inactive R-enantiomer competes with the serotonin-enhancing S-enantiomer at a low-affinity allosteric site on serotonin reuptake transporters (SERTs), and reduces the effectiveness of the S-enantiomer at the primary, high-affinity serotonin-binding site. This study summarizes the results of two recent single-photon emission computerized tomography studies measuring SERT occupancy in citalopram-treated and escitalopram-treated healthy volunteers, after a single dose and multiple doses (i.e. under steady-state conditions). The single-dose study showed no attenuating effect of R-citalopram. After multiple dosing, however, SERT occupancy was significantly reduced in the presence of R-citalopram. Under steady-state conditions, R-enantiomer concentrations were greater than for the S-enantiomer because of slower clearance of R-citalopram. A pooled analysis suggests that build-up of the R-enantiomer after repeated citalopram dosing may lead to increased inhibition of S-enantiomer occupancy of SERT. This review adds to the growing body of evidence regarding differences in the dynamics of SERT occupancy, that is, molecular mechanisms underlying the often-observed superior clinical efficacy of escitalopram compared with citalopram in major depressive disorder.

For the assessment of personal exposure, information about the concentration of pollutants when people are in given indoor environments (occupancy time) are of prime importance. However this kind of data frequently is not reported. The aim of this study was to assess differences in particle characteristics between occupancy time and the total monitoring period, with the latter being the most frequently used averaging time in the published data. Seven indoor environments were selected in Sweden and Finland: an apartment, two houses, two schools, a supermarket, and a restaurant. They were assessed for particle number and mass concentrations and number size distributions. The measurements using a Scanning Mobility Particle Sizer and two photometers were conducted for seven consecutive days during winter in each location. Particle concentrations in residences and schools were, as expected, the highest during occupancy time. In the apartment average and median PM2.5 mass concentrations during the occupancy time were 29% and 17% higher, respectively compared to total monitoring period. In both schools, the average and medium values of the PM2.5 mass concentrations were on average higher during teaching hours compared to the total monitoring period by 16% and 32%, respectively. When it comes to particle number concentrations (PNC), in the apartment during occupancy, the average and median values were 33% and 58% higher, respectively than during the total monitoring period. In both houses and schools the average and median PNC were similar for the occupancy and total monitoring periods. General conclusions on the basis of measurements in the limited number of indoor environments cannot be drawn. However the results confirm a strong dependence on type and frequency of indoor activities that generate particles and site specificity. The results also indicate that the exclusion of data series during non-occupancy periods can improve the estimates of particle concentrations and

The Global Burden of Occupational Disease.

2017-09-01

Burden of occupational disease estimation contributes to understanding of both magnitude and relative importance of different occupational hazards and provides essential information for targeting risk reduction. This review summarises recent key findings and discusses their impact on occupational regulation and practice. New methods have been developed to estimate burden of occupational disease that take account of the latency of many chronic diseases and allow for exposure trends and workforce turnover. Results from these studies have shown in several countries and globally that, in spite of improvements in workplace technology, practices and exposures over the last decades, occupational hazards remain an important cause of ill health and mortality worldwide. Major data gaps have been identified particularly regarding exposure information. Reliable data on employment and disease are also lacking especially in developing countries. Burden of occupational disease estimates form an important part of decision-making processes.

Different functional classes of genes are characterized by different compositional properties.

A compositional analysis on a set of human genes classified in several functional classes was performed. We found out that the GC3, i.e. the GC level at the third codon positions, of the genes involved in cellular metabolism was significantly higher than those involved in information storage and processing. Analyses of human/Xenopus ortologous genes showed that: (i) the GC3 increment of the genes involved in cellular metabolism was significantly higher than those involved in information storage and processing; and (ii) a strong correlation between the GC3 and the corresponding GCi, i.e. the GC level of introns, was found in each functional class. The non-randomness of the GC increments favours the selective hypothesis of gene/genome evolution.

Occupational therapy is a global profession represented by the World Federation of Occupational Therapists (WFOT). International research priorities are needed for strategic guidance on global occupational therapy practice. The objective of this study was to develop international research priorities to reflect global occupational therapy practice. A Delphi study using three rounds of electronic surveys, distributed to WFOT member organizations and WFOT accredited universities, was conducted. Data were analyzed after each round, and priorities were presented for rating and ranking in order of importance. Forty-six (53%) out of 87 WFOT member countries participated in the Delphi process. Eight research priorities were confirmed by the final electronic survey round. Differences were observed in rankings given by member organizations and university respondents. Despite attrition at Round 3, the final research priorities will help to focus research efforts in occupational therapy globally. Follow-up research is needed to determine how the research priorities are being adopted internationally.

Occupational cancer in Britain. Preventing occupational cancer.

PubMed

Chen, Yiqun; Osman, John

2012-06-19

Although only a relatively small proportion of cancer is attributable to occupational exposure to carcinogenic agents, the estimated number of deaths due to occupational cancer is high when compared to other deaths due to work-related ill health and injury. However, risk from occupational exposure to carcinogens can be minimised through proportionate but effective risk management. The Health and Safety Executive (HSE) is the regulator of workplace health and safety in Great Britain. As part of its aim to reduce ill health arising from failures to control properly exposure to hazards at work, HSE commissioned the research presented elsewhere in this supplement to enable it to identify priorities for preventing occupational cancer. The research has shown that occupational cancer remains a key health issue and that low-level exposure of a large number of workers to carcinogens is important. The finding that a small number of carcinogens have been responsible for the majority of the burden of occupational cancer provides key evidence in the development of priorities for significant reduction of occupational cancer. Although the research presented in this supplement reflects the consequences of past exposures to carcinogens, occupational cancer remains a problem. The potential for exposure to the agents considered in this research is still present in the workplace and the findings are relevant to prevention of future disease. In this article, the principle approaches for risk reduction are described. It provides supporting information on some of the initiatives already being undertaken, or those being put in place, to reduce occupational cancer in Great Britain. The need also for systematic collection of exposure information and the importance of raising awareness and changing behaviours are discussed.

[Occupational cancer].

Occupational cancer is one of the most important topics in occupational health, because it can be avoided by using appropriate risk management strategies at work. However, due to the lack of suitable surveillance systems in Japan, it goes under-recognized. Burden of disease studies conducted elsewhere can be extrapolated to suggest thousands of deaths are attributable to occupational cancer in Japan. By law, about 20 kinds of cancer have been listed as occupational hazards; among those is asbestos related cancer. In fact, in recent years, thousands of asbestos related cancer cases have been compensated by the government run workers' compensation scheme for occupational accidents and diseases. On the other hand, for the other types of occupational cancer, only few cases are reported. To prevent re-emergence of occupational cancer, such as the recently publicized cholangiocarcinoma epidemics, employees, employers, medical institutions and competent authorities are strongly urged to establish better surveillance systems for occupational cancer.

Safety climate and occupational stress are related with occupational accident. The present study tried to identify the differences in safety climate and occupational stress according to occupational accidents experience and employment type (e.g., direct workers and subcontract workers). In this study, we conducted a survey using safety climate scale and Korean Occupational Stress Scale and classified the participants into four groups: direct workers working for accident-free departments, direct workers working for accident departments, subcontract workers working for accident-free departments, and subcontract workers working for accident departments for 2 years within the same workplace in the shipbuilding industry. The direct workers and subcontract workers showed diverse results in subscales of safety climate and occupational stress. This result is supported by existing studies; however, further study is necessary for more supporting evidence and elaborative methodological approach. The necessity of management for safety climate and psychosocial factor such as occupational stress for both direct workers and subcontract workers as a whole is suggested by this study.

Use of indicator species as a measure of ecosystem conditions is an established science application in environmental management. Because of its role in shaping wetland systems, the American alligator (Alligator mississippiensis) is one of the ecological indicators for wetland restoration in south Florida, USA. We conducted landscape-level aerial surveys of alligator holes in two different habitats in a wetland where anthropogenic modification of surface hydrology has altered the natural system. Alligator holes were scarcer in an area where modified hydrology caused draining and frequent dry-downs compared to another area that maintains a functional wetland system. Lower abundance of alligator holes indicates lack of alligator activities, lower overall species diversity, and lack of dry-season aquatic refugia for other organisms. The occupancy rate of alligator holes was lower than the current restoration target for the Everglades, and was variable by size class with large size-class alligators predominantly occupying alligator holes. This may indicate unequal size-class distribution, different habitat selection by size classes, or possibly a lack of recruitment. Our study provides pre-restoration baseline information about one indicator species for the Everglades. Success of the restoration can be assessed via effective synthesis of information derived by collective research efforts on the entire suite of selected ecological indicators.

In this article, findings from a qualitative study of a cohort of occupational therapy students in Auckland, New Zealand are presented. The study focussed on the experiences of students as they learned to work with people from different social and cultural backgrounds over a 3-year period. As well as identifying curriculum and teaching/learning processes that enhance intercultural competence development, the data that emerged from the study also highlight important issues about how occupation and independence are conceptualised across cultures. A review of the trans-disciplinary and occupational therapy literature dealing with theoretical, conceptual and educational issues relating to cross-cultural practice is followed by a presentation of narrative extracts that address the key concepts of occupation and independence. These are then discussed with reference to relevant occupational therapy literature. In conclusion, implications for future research and practice are explored focussing on a need for occupation and independence to be reconsidered as culturally relative constructions.

An outbreak of cholangiocarcinoma has been reported among workers of an offset color proof-printing department at a printing company in Japan. In this study, we compared the clinicopathological findings of this type of intrahepatic cholangiocarcinoma (occupational ICC) and non-occupational ICC. The clinical records of 51 patients with perihilar-type ICC who underwent liver resection, including five patients with occupational ICC were retrospectively reviewed. The clinicopathological features were compared. In the occupational group, the patients were significantly younger (P < 0.01), while serum γ-glutamyl transpeptidase activity and the proportions of patients with regional dilatation of the bile ducts without tumor-induced obstruction were significantly higher (P = 0.041 and P < 0.01, respectively); the indocyanine green retention rate at 15 min was significantly lower (P = 0.020). On pathological examinations, precancerous or early cancerous lesions, such as biliary intraepithelial neoplasia and intraductal papillary neoplasm of the bile duct, were observed at various sites of the bile ducts in all occupational ICC patients; such lesions were observed in only six patients in the control group (P < 0.01). The clinicopathological findings including age, liver function test results, diagnostic imaging findings, and pathological findings differed between the occupational and control groups. © 2016 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Eye injuries from foreign body incidents remain prevalent in the workplace setting. Often the professional nurse provides the first line of treatment. The informal class presented at the authors' facility offered a comprehensive, organized presentation of a common injury encountered in the practice of occupational health nursing. Strenghts of the presentation included handouts demonstrating eye eversion technique and a flip chart summarizing the content to be placed in each medical station as quick reference. One challenge involved presenting the information to all nurses. The site encompasses four locations and some nurses function as the only staff in the plant for a given shift. With the support of administration and some creative scheduling, 10 of 17 nurses attended one of three classes offered in one morning, and the remaining 7 were able to view the class on videotape. Videotaping the presentation also provided material for future orientation, as well as an opportunity for review. Overall analysis found this a worthwhile offering relevant to practice. A brief formal written evaluation indicated the objectives for the class were achieved and elicited subjects for future topics. Informal chart reviews to check for documentation of visual acuity testing and eversion of the upper lid for foreign body injuries is another outcome measure currently in progress. In addition, a performance improvement project could be accomplished easily by retrospective chart review of assessment and treatment documentation, and tracking of revisits and referrals. Knowledge of current standards in the assessment, first aid, and treatment of eye injuries is every occupational health nurse's responsibility. However, prevention of foreign body injuries is far superior to any treatment modality available. As highly visible leaders within the occupational setting, nurses can be advocates and role models for safe work practices. Occupational health nurses may promote safe eye practices by

In vivo imaging of serotonin transporter occupancy by means of SPECT and [123I]ADAM in healthy subjects administered different doses of escitalopram or citalopram.

Escitalopram is a dual serotonin reuptake inhibitor (SSRI) approved for the treatment of depression and anxiety disorders. It is the S-enantiomer of citalopram, and is responsible for the serotonin reuptake activity, and thus for its pharmacological effects. Previous studies pointed out that clinically efficacious doses of other SSRIs produce an occupancy of the serotonin reuptake transporter (SERT) of about 80% or more. The novel radioligand [123I]ADAM and single photon emission computer tomography (SPECT) were used to measure midbrain SERT occupancies for different doses of escitalopram and citalopram. Twenty-five healthy subjects received a single dose of escitalopram [5 mg (n=5), 10 mg (n=5), and 20 mg (n=5)] or citalopram [(10 mg (n=5) and 20 mg (n=5)]. Midbrain SERT binding was measured with [(123)I]ADAM and SPECT on two study days, once without study drug and once 6 h after single dose administration of the study drug. The ratio of midbrain-cerebellum/cerebellum was the outcome measure (V3") for specific binding to SERT in midbrain. Subsequently, SERT occupancy levels were calculated using the untreated baseline level for each subject. An Emax model was used to describe the relationship between S-citalopram concentrations and SERT occupancy values. Additionally, four subjects received placebo to determine test-retest variability. Single doses of 5, 10, or 20 mg escitalopram led to a mean SERT occupancy of 60+/-6, 64+/-6, and 75+/-5%, respectively. SERT occupancies for subjects treated with single doses of 10 and 20 mg citalopram were 65+/-10 and 70+/-6%, respectively. A statistically significant difference was found between SERT occupancies after application of 10 and 20 mg escitalopram, but not for 10 and 20 mg citalopram. There was no statistically significant difference between the SERT occupancies of either 10 mg citalopram or 10 mg escitalopram, or between 20 mg citalopram and 20 mg escitalopram. Emax was slightly higher after administration of

Occupational health and safety among commercial sex workers.

The concept of occupational health and safety (OHS) for commercial sex workers has rarely been investigated, perhaps because of the often informal nature of the workplace, the associated stigma, and the frequently illegal nature of the activity. We reviewed the literature on health, occupational risks, and safety among commercial sex workers. Cultural and local variations and commonalities were identified. Dimensions of OHS that emerged included legal and policing risks, risks associated with particular business settings such as streets and brothels, violence from clients, mental health risks and protective factors, alcohol and drug use, repetitive strain injuries, sexually transmissible infections, risks associated with particular classes of clients, issues associated with male and transgender commercial sex workers, and issues of risk reduction that in many cases are associated with lack of agency or control, stigma, and legal barriers. We further discuss the impact and potential of OHS interventions for commercial sex workers. The OHS of commercial sex workers covers a range of domains, some potentially modifiable by OHS programs and workplace safety interventions targeted at this population. We argue that commercial sex work should be considered as an occupation overdue for interventions to reduce workplace risks and enhance worker safety.

The term "professional dance" comprises various dance styles. There are no studies which investigated work related traumatic injuries with regard to five different dance styles. To define dance-style related differences of traumatic injuries. The basis for the evaluation were the occupational injuries of professional dancers of six theaters (n=1339; f: n=658, m: n=681) and one State Ballet School (n=612; f:n=421, m: n=191). Independent of the dance style, the lower extremity (leg and hip) is the most frequently injured anatomical region (p< 0.001). The more dancers move away from the classical dance technique, the more traumatic head/neck injuries increase (p<0.001). Injury patterns and injured structures also show differences subject to dance styles (p< 0.001). In classical dance the most commonly sustained injuries are due to intrinsic factors with the significance of extrinsic factors increasing the more dancers diverge from defined classical dance techniques. The results shown in the study clarify the enormous dance-style related differences in traumatic injuries sustained by dancers. These differences support the development of dance-style related injury prevention measures and suggest further investigations with the focus being placed on the influence of organizational structures (e.g. number of performances) as well as on the working environments.

Higher-status occupations and breast cancer: a life-course stress approach.

Using the 1957-2011 data from 3682 White non-Hispanic women (297 incident breast cancer cases) in the Wisconsin Longitudinal Study, United States, we explore the effect of occupation in 1975 (at age 36) on breast cancer incidence up to age 72. Our study is motivated by the paradoxical association between higher-status occupations and elevated breast cancer risk, which presents a challenge to the consistent health advantage of higher social class. We found that women in professional occupations had 72122% and women in managerial occupations had 57-89% higher risk of a breast cancer diagnosis than housewives and women in lower-status occupations. We explored an estrogen-related pathway (reproductive history, health behaviors, and life-course estrogen cycle) as well as a social stress pathway (occupational experiences) as potential explanations for the effect of higher-status occupations. The elevated risk of breast cancer among professional women was partly explained by estrogen-related variables but remained large and statistically significant. The association between managerial occupations and breast cancer incidence was fully explained by job authority defined as control over others' work. Exercising job authority was related to higher breast cancer risk (HR = 1.57, 95% CI: 1.12, 2.18), especially with longer duration of holding the professional/managerial job. We suggest that the assertion of job authority by women in the 1970s involved stressful interpersonal experiences that may have promoted breast cancer development via prolonged dysregulation of the glucocorticoid system and exposure of the breast tissue to adverse effects of chronically elevated cortisol. Our study emphasizes complex biosocial pathways through which women's gendered occupational experiences become embodied and drive forward physiological repercussions. Copyright © 2013 Elsevier Ltd.

2017-10-01

We present and propose a complete and iterative integrated-circuit and electro-magnetic (EM) co-design methodology and procedure for a low-voltage sub-1 GHz class-E PA. The presented class-E PA consists of the on-chip power transistor, the on-chip gate driving circuits, the off-chip tunable LC load network and the off-chip LC ladder low pass filter. The design methodology includes an explicit design equation based circuit components values' analysis and numerical derivation, output power targeted transistor size and low pass filter design, and power efficiency oriented design optimization. The proposed design procedure includes the power efficiency oriented LC network tuning, the detailed circuit/EM co-simulation plan on integrated circuit level, package level and PCB level to ensure an accurate simulation to measurement match and first pass design success. The proposed PA is targeted to achieve more than 15 dBm output power delivery and 40% power efficiency at 433 MHz frequency band with 1.5 V low voltage supply. The LC load network is designed to be off-chip for the purpose of easy tuning and optimization. The same circuit can be extended to all sub-1 GHz applications with the same tuning and optimization on the load network at different frequencies. The amplifier is implemented in 0.13 μm CMOS technology with a core area occupation of 400 μm by 300 μm. Measurement results showed that it provided power delivery of 16.42 dBm at antenna with efficiency of 40.6%. A harmonics suppression of 44 dBc is achieved, making it suitable for massive deployment of IoT devices.

The definition of fat differs in different countries; thus whether fat is listed on food labels depends on the country. Some countries list crude fat content in the 'Fat' section on the food label, whereas other countries list total fat. In this study, three methods were used for determining fat classes and content in bakery products: the Folch method, the automated Soxhlet method, and the AOAC 996.06 method. The results using these methods were compared. Fat (crude) extracted by the Folch and Soxhlet methods was gravimetrically determined and assessed by fat class using capillary gas chromatography (GC). In most samples, fat (total) content determined by the AOAC 996.06 method was lower than the fat (crude) content determined by the Folch or automated Soxhlet methods. Furthermore, monounsaturated fat or saturated fat content determined by the AOAC 996.06 method was lowest. Almost no difference was observed between fat (crude) content determined by the Folch method and that determined by the automated Soxhlet method for nearly all samples. In three samples (wheat biscuits, butter cookies-1, and chocolate chip cookies), monounsaturated fat, saturated fat, and trans fat content obtained by the automated Soxhlet method was higher than that obtained by the Folch method. The polyunsaturated fat content obtained by the automated Soxhlet method was not higher than that obtained by the Folch method in any sample. Copyright © 2012 Elsevier Ltd. All rights reserved.

A robot platform includes perceptors, locomotors, and a system controller. The system controller executes instructions for producing an occupancy grid map of an environment around the robot, scanning the environment to generate a current obstacle map relative to a current robot position, and converting the current obstacle map to a current occupancy grid map. The instructions also include processing each grid cell in the occupancy grid map. Within the processing of each grid cell, the instructions include comparing each grid cell in the occupancy grid map to a corresponding grid cell in the current occupancy grid map. For grid cells with a difference, the instructions include defining a change vector for each changed grid cell, wherein the change vector includes a direction from the robot to the changed grid cell and a range from the robot to the changed grid cell.

Chronic stress may produce a decrease in central NPY expression and subjects exposed to it may prove hypersensitivity to a novel stressor with dysfunctions in the NPY system and cardiovascular maladaptation to stress, even hypertension. Upregulation of NPY expression may contribute to successful behavioral adaptation to stress by reducing cardiovascular tone and suppressing anxious behaviors. Adaptogens, a new class of metabolic regulators stimulate NPY expression and release. The aim of this study is to increase tolerance and adaptation to stress of hypersensitive to novel stressor, occupational chronic stress exposed subjects with cardiovascular maladaptation to mild new stressor using adaptogens as part of prevention protocol. 40 military personnel with known cardiostressor reactional mode and occupational chronic stress exposure were exposed to mild novel stressor: occupational medicine routine evaluation and clinically assessed for maladaptative cardiovascular response prior and before application of 30 day prevention protocol. Employees were randomly split in two groups, one receiving standard prevention protocol (lifestyle counseling) plus adaptogens in multiple dose administration, twice daily and the other receiving only standard prevention protocol. We found significant statistic differences in all cardiovascular parameters in adaptogen group and only in diastolic blood pressure in control group. Adaptogens could be an important factor in successful prevention protocols of chronic occupational stress dysfunctions involving NPY systems.

Using positron emission tomography and the carbon 11-labeled ligand raclopride, central D2-dopamine receptor occupancy in the putamen was determined in psychiatric patients treated with clinical doses of psychoactive drugs. Receptor occupancy in drug-treated patients was defined as the percent reduction of specific carbon 11-raclopride binding in relation to the expected binding in the absence of drug treatment. Clinical treatment of schizophrenic patients with 11 chemically distinct antipsychotic drugs (including both classic and atypical neuroleptics such as clozapine) resulted in a 65% to 85% occupancy of D2-dopamine receptors. In a depressed patient treated with the tricyclic antidepressant nortriptyline, no occupancy wasmore » found. The time course for receptor occupancy and drug levels was followed after withdrawal of sulpiride or haloperidol. D2-dopamine receptor occupancy remained above 65% for many hours despite a substantial reduction of serum drug concentrations. In a sulpiride-treated patient, the dosage was reduced in four steps over a nine-week period and a curvilinear relationship was demonstrated between central D2-dopamine receptor occupancy and serum drug concentrations. The results demonstrate that clinical doses of all the currently used classes of antipsychotic drugs cause a substantial blockade of central D2-dopamine receptors in humans. This effect appears to be selective for the antipsychotics, since it was not induced by the antidepressant nortriptyline.« less

Inappropriate verbal behavior that is labeled “psychotic” is often described as insensitive to environmental contingencies. The purpose of the current study was to establish different classes of rational or appropriate verbal behavior in a woman with developmental disabilities and evaluate the effects on her psychotic or aberrant vocal verbal behavior. Similar to a previous study (Arntzen, Ro Tonnessen, & Brouwer, 2006), the results of the current study suggested that the procedure helped to establish a repertoire of appropriate functional vocal verbal behavior in the participant. Overall, the results suggested the effectiveness of an intervention based on training various classes of verbal behavior in decreasing aberrant verbal behavior. PMID:22754112

Occupational health in Brazil.

Brazil is a recently industrialised country with marked contrasts in social and economic development. The availability of public/private services in its different regions also varies. Health indicators follow these trends. Occupational health is a vast new field, as in other developing countries. Occupational medicine is a required subject in graduation courses for physicians. Specialisation courses for university graduated professionals have more than 700 hours of lectures and train occupational health physicians, safety engineers and nursing staff. At the technical level, there are courses with up to 1300 hours for the training of safety inspectors. Until 1986 about 19,000 occupational health physicians, 18,000 safety engineers and 51,000 safety inspectors had been officially registered. Although in its infancy, postgraduation has attracted professionals at university level, through residence programmes as well as masters and doctors degrees, whereby at least a hundred good-quality research studies have been produced so far. Occupational health activities are controlled by law. Undertakings with higher risks and larger number of employees are required to hire specialised technical staff. In 1995 the Ministry of Labour demanded programmes of medical control of occupational health (PCMSO) for every worker as well as a programme of prevention of environmental hazards (PPRA). This was considered as a positive measure for the improvement of working conditions and health at work. Physicians specialising in occupational medicine are the professionals more often hired by the enterprises. Reference centres (CRSTs) for workers' health are connected to the State or City Health Secretariat primary health care units. They exist in more populated areas and are accepted by workers as the best way to accomplish the diagnosis of occupational diseases. There is important participation by the trade unions in the management of these reference centres. For 30 years now employers

Unbelted occupants may increase the risk of injury for other occupants in a motor vehicle collision (MVC). This study evaluated the association between occupant restraint use and the risk of injury (including death) to other vehicle occupants. A population based cohort study. United States. MVC occupants (n = 152 191 unweighted, n = 18 426 684 weighted) seated between a belted or unbelted occupant and the line of the principal direction of force in frontal, lateral, and rear MVCs were sampled from the 1991-2002 National Automotive Sampling System General Estimates System. Offset MVCs were not included in the study. Risk ratios and 95% confidence intervals for injury (including death) for occupants seated contiguous to unbelted occupants compared to occupants seated contiguous to belted occupants. Risk ratios were adjusted for at risk occupant's sex, age, seating position, vehicle type, collision type, travel speed, crash severity, and at risk occupants' own seat belt use. Exposure to unbelted occupants was associated with a 40% increased risk of any injury. Belted at risk occupants were at a 90% increased risk of injury but unbelted occupants were not at increased risk. Risks were similar for non-incapacitating and capacitating injuries. There was a 4.8-fold increased risk of death for exposed belted occupants but no increased risk of death for unbelted occupants. Belted occupants are at an increased risk of injury and death in the event of a MVC from unbelted occupants.
