What is the impact of job precariousness on depression? Risk assessment and attributable fraction in Spain.

OBJECTIVES: The prevalence of depression related to precarious employment (PE) has become a significant public health concern, given the declining trend of the standard employment relationship. Research has focused on the mental health detrimental effects of employment conditions, whereas there is scarce evidence concerning the burden of depression that could be prevented by targeting precariousness. This paper estimates the impact of PE on the risk of depression and the attributable fraction within the active and working salaried population in Spain. STUDY DESIGN: Observational cross-sectional on data drawn from the Spanish portion of European Health Survey 2020. METHODS: After applying selection criteria and descriptives, binary logistic regression models stratified by sex are used to examine the associations between a 9-categories combination of employment precariousness and occupational social class, and depressive symptoms. RESULTS: There is a higher risk of depression among individuals in PE and among those who are unemployed, with a notable gradient based on occupational social class for women. Adjusting by sex, age and foreign-born origin, we estimate that approximately 15.0% (95% confidence interval [CI]: 1.0%-26.2%) of depression cases among the working population and 33.3% (95% CI: 23.2%-43.2) among the active population can be attributed to PE. CONCLUSIONS: These findings highlight the public health impact of PE on mental health, provide evidence to estimate the economic burden linked to employment-related mental health, and underscore the need for policy changes and interventions at the level of labour markets and workplaces to mitigate the detrimental effects of PE.

Precarious employment: understanding an emerging social determinant of health.

Employment precariousness is a social determinant that affects the health of workers, families, and communities. Its recent popularity has been spearheaded by three main developments: the surge in "flexible employment" and its associated erosion of workers' employment and working conditions since the mid-1970s; the growing interest in social determinants of health, including employment conditions; and the availability of new data and information systems. This article identifies the historical, economic, and political factors that link precarious employment to health and health equity; reviews concepts, models, instruments, and findings on precarious employment and health inequalities; summarizes the strengths and weaknesses of this literature; and highlights substantive and methodological challenges that need to be addressed. We identify two crucial future aims: to provide a compelling research program that expands our understanding of employment precariousness and to develop and evaluate policy programs that effectively put an end to its health-related impacts.

Motivations of nurses who migrate to Canada as domestic workers.

BACKGROUND: While some trained nurses migrate to destination countries to work as domestic workers, little is known about their migration motivations. AIM: This study explores the motivations of Philippine educated nurses who migrated to Canada through the Live-in Caregiver Program from 2001 to 2011 (a Canadian domestic worker programme). METHODS: A single case study qualitative methodology and the transnational feminist concept of global care chains were utilized for this study. Interviews of 15 Philippine educated nurses who migrated to Canada as domestic workers were conducted in the province of Ontario, Canada, between February to October 2012. All participants had a baccalaureate degree from the Philippines. Interviews were tape recorded, transcribed verbatim and analysed using critical discourse analysis, aided by NVIVO 10 data analysis software. RESULTS: Findings reveal a multi-step immigration process in which nurses migrate from the Philippines to the Middle East (especially Saudi Arabia) and finally to Canada. While emigration from the Philippines is mainly economically driven, migration from the Middle East to Canada is primarily motivated by the desire for Canadian citizenship for the family. Also, perceived social status and lifestyle in Canada as compared to the Middle East motivates this group of women to migrate to Canada. LIMITATION: The major limitation of this study is the lack of input from nursing policy makers. CONCLUSION: Gender-based familial ideologies and perspective on social status influence the migration decision of this group of nurses. IMPLICATIONS FOR NURSING AND HEALTH POLICY: Implications for nursing and health policy makers include the provision of clear pre-migration information (including on the nursing registration process) to internationally educated nurses, advocacy for stronger immigration policies to ensure the integration of internationally educated nurses and a consideration of gender in all health human resource policies.

A multi-group cross-lagged analyses of work stressors and health using Canadian National sample.

This article examines the reciprocal relationships between work variables and health outcomes and if these relationships differ by social class (measured by occupational grouping). We used longitudinal data from the 1994/95--2002/03 Canadian National Population Health Survey (NPHS). Karasek's work stress variables were measured in the 1994/95 (cycle 1, time 1), 2000/01 (cycle 4, time 2) and 2002/03 (cycle 5, time 3) surveys. Analyses were limited to 2556 respondents aged 18-56 at time 1 and who remained in the same social class (as defined by occupational position) for all the three time points. Work variables used were job strain ratio, work social support and job insecurity. Health outcomes used were distress, depression and self-rated health. Multi-group path analyses were used to investigate the reciprocal relationships between work and health variables and if these relationships differed by social class. Analyses controlled for age, gender, marital status and work status. We find there is a differential burden of work psychosocial factors and health outcomes by social class. The cross-lagged relationships between work and health depended on the outcome, social class and time lag. More significant paths from work to health were observed than reverse paths from health to work. More significant relationships between work and health were observed for the shorter time lag (2 years) compared to longer time lags (6 years). Low work social support and job insecurity were more detrimental to health for respondents in lower social class positions. Findings from this study highlight the importance of time lag, and to some extent social class, in the reciprocal relationships between work and health.

Retrenched Welfare Regimes Still Lessen Social Class Inequalities in Health: A Longitudinal Analysis of the 2003-2010 EU-SILC in 23 European Countries.

This article builds on recent work that has explored how welfare regimes moderate social class inequalities in health. It extends research to date by using longitudinal data from the EU-SILC (2003-2010) and examines how the relationship between social class and self-reported health and chronic conditions varies across 23 countries, which are split into five welfare regimes (Nordic, Anglo-Saxon, Eastern, Southern, and Continental). Our analysis finds that health across all classes was only worse in Eastern Europe (compared with the Nordic countries). In contrast, we find evidence that the social class gradient in both measures of health was significantly wider in the Anglo-Saxon and Southern regimes. We suggest that this evidence supports the notion that welfare regimes continue to explain differences in health according to social class location. We therefore argue that although downward pressures from globalization and neoliberalism have blurred welfare regime typologies, the Nordic model may continue to have an important mediating effect on class-based inequalities in health.

Associations between temporary employment and occupational injury: what are the mechanisms?

OBJECTIVE: To determine whether observed higher risks of occupational injury among temporary workers are due to exposure to hazardous working conditions and/or to lack of job experience level. METHODS: Data systematically recorded for 2000 and 2001 by the Spanish Ministry of Labour and Social Affairs on fatal and non-fatal traumatic occupational injuries were examined by type of employment and type of accident, while adjusting for gender, age, occupation, and length of employment in the company. In the study period there were 1500 fatal and 1 806 532 non-fatal traumatic occupational injuries that occurred at the workplace. Incidence rates and rate ratios (RR) were estimated using Poisson regression models. RESULTS: Temporary workers showed a rate ratio of 2.94 for non-fatal occupational injuries (95% CI 2.40 to 3.61) and 2.54 for fatal occupational injuries (95% CI 1.88 to 3.42). When these associations were adjusted by gender, age, occupation, and especially length of employment, they loose statistic significance: 1.05 (95% CI 0.97 to 1.12) for non-fatal and 1.07 (95% CI 0.91 to 1.26) for fatal. CONCLUSIONS: Lower job experience and knowledge of workplace hazards, measured by length of employment, is a possible mechanism to explain the consistent association between temporary workers and occupational injury. The role of working conditions associated with temporary jobs should be assessed more specifically.

What should we know about precarious employment and health in 2025? Framing the agenda for the next decade of research.

The generalization of flexible labour markets, the declining influence of unions and the degradation of social protection has led to the emergence of new forms of employment at the expense of the Standard Employment Relationship, as well as a considerable amount of research across social and scientific disciplines. Years ago we suggested the urgent need to disentangle the consequences of new types of employment for the health and well-being of workers, contending that the study of precarious employment and health is in its infancy. Today, research challenges include clearer, more precise definitions of the original concepts, a more detailed understanding of the pathways and mechanisms through which precarious employment harms worker health, stronger information systems for monitoring the problem and a complex systems approach to employment conditions and health research. All of these must be guided by the theoretical and policy debates linking precarious employment and health, and be geared towards developing better tools for the design, implementation and evaluation of policies intended to minimize precariousness in the labour market and its effects on public health and health inequalities. Our aim in this paper is to outline an agenda for the next decade of research on precarious employment and health, establishing a compelling programme that expands our understanding of complex causes and links.

The impact of social conditions on patient adherence to pulmonary tuberculosis treatment.

SETTING: Tuberculosis (TB) remains one of the main concerns in global health. One of the main threats to treatment success is patient non-adherence to anti-tuberculosis treatment. OBJECTIVE: To identify the relation between social conditions and treatment adherence in a prospective cohort setting in an intermediate TB burden country. DESIGN: To identify associations between poor adherence and social conditions, including educational level, type of residence and occupation, we constructed hierarchical logistic regression models. RESULTS: A total of 551 participants were included in the study. Low educational levels, poor housing and occupations in the construction and manufacturing industries and service sectors were associated with poor adherence; this association was likely to be differentiated by previous history of anti-tuberculosis treatment. CONCLUSION: Policy making should focus on improving the social conditions of patients by working towards better housing conditions and providing health promoting working conditions to enable treatment adherence.

Cardiovascular responses to cocaine placebo in humans: a preliminary report.

Cardiovascular responses after placebo-cocaine injections were in the same direction as the effect of cocaine iv in 22 male volunteers. Subjects received iv placebo in a room where they had been given repeated doses of iv cocaine. The placebo response consisted of an increase from baseline values of systolic and diastolic blood pressure and pulse rate. The control group, 8 subjects, which was not exposed to a conditioning phase, showed a smaller increase in the pulse rate and systolic blood pressure after the placebo injection. The results, in accordance with animal literature, suggest the existence of cocaine-conditioned effects in humans.

Occupational hierarchy, economic sector, and mortality from cardiovascular disease among men and women. Findings from the National Longitudinal Mortality Study.

PURPOSE: Although socioeconomic position has been identified as a determinant of cardiovascular disease among employed men and women in the U.S., the role of economic sector in shaping this relationship has yet to be examined. We sought to estimate the combined effects of economic sector-one of the three major sectors of the economy: finance, government and production-and socioeconomic position on cardiovascular mortality among employed men and women. METHODS: Approximately 375,000 men and women 25 years of age or more were identified from selected Current Population Surveys between 1979 and 1985. These persons were followed for cardiovascular mortality through use of the National Death Index for the years 1979 through 1989. RESULTS: In men, the lowest cardiovascular mortality was found for professionals in the finance sector (76/100,000 person/years). The highest cardiovascular mortality was found among male non-professional workers in the production sector (192/100,000 person years). A different pattern was observed among women. Professional women in the finance sector had the highest rates of cardiovascular mortality (133/100,000 person years). For both men and women, the professional/non-professional gap in cardiovascular mortality was lower in the government sector than in the production and finance sectors. These associations were strong even after adjustment for age, race and income. CONCLUSIONS: Characteristics of government, finance and production work differentially influence the risk of cardiovascular disease mortality. Men, women, professionals and non-professionals experience this risk differently.

Effects of nifedipine pretreatment on subjective and cardiovascular responses to intravenous cocaine in humans.

The effects of oral nifedipine pretreatment on subjective and cardiovascular responses to intravenous cocaine infusions were studied in cocaine-using volunteers. Nifedipine, 10 mg or placebo, was administered 20-25 min before placebo, 20 mg, or 40 mg cocaine, using a repeated measures randomized double-blind design. The variables measured were self-reported subjective effects, general behavior rated by two observers, blood pressure and heart rate. Cocaine produced the expected dose-related effects on subjective and cardiovascular measures. Nifedipine pretreatment attenuated some subjective effects of cocaine. Nifedipine directly reduced blood pressure but did not antagonize the effects of cocaine on blood pressure. These findings suggest that dihydropyridine calcium channel modulators may be useful compounds in the clinical management of cocaine users.

Placebo responses to cocaine administration in humans: effects of prior administrations and verbal instructions.

Subjective and physiological responses of eight male cocaine-using research volunteers were studied after a double-blind saline infusion (placebo) was given when subjects were instructed that a cocaine infusion might be given. Cardiovascular and subjective responses to placebo were similar in pattern and direction, though of lesser magnitude, than after a 40 mg cocaine infusion. These placebo responses were compared to responses after an earlier saline infusion condition in which subjects were instructed prior to the infusion that they would receive saline (instructed placebo). The design was thus meant to test for the effects of instructions on placebo responses to cocaine. Heart rates at baseline (pre-infusion) were significantly higher in the placebo than in the instructed placebo condition. Similar trends were found for elevated baseline placebo responses on two subjective effects measures. A comparison with an initial placebo session prior to the placebo and instructed placebo conditions described above provided evidence for conditioning of placebo responses on diastolic blood pressure and heart rate. The present results suggest that verbal instructions, as well as conditioning in the laboratory, could contribute to the observed placebo responses to cocaine infusions.

Work organization and atherosclerosis: findings from the ARIC study. Atherosclerosis Risk in Communities.

INTRODUCTION: The aim of this investigation was to examine the extent to which work organization (i.e., occupational stress) is associated with subclinical carotid atherosclerosis. METHODS: For that purpose we used a cross-sectional study of four U.S. community samples conducted between 1987 and 1989. Participants in the study were 10,801 adults aged 45 to 64 years. Subclinical carotid atherosclerosis was assessed by measuring the intima-media thickness (IMT) of the carotid artery wall using B-mode ultrasound. Occupational stress was defined using six indicators: substantive complexity of work, physical demands, job insecurity, skill discretion, decision authority, and physical exertion. Information from U.S. national surveys on occupational stress indicators was linked to the study participants' occupation. RESULTS: We observed negative associations of complexity of work and skill discretion with mean IMT of the carotid artery wall among the four race-gender groups. In addition, physical demands was positively associated with mean IMT among blacks and job insecurity was positively associated with IMT among white women and black men. After adjustment for well-established risk factors, the magnitude of these associations was substantially reduced. CONCLUSIONS: Taken in combination with results from recent European studies, our findings suggest that work organization plays a role in the etiology of atherosclerosis.

Effects of self-reported drug use and antisocial behavior on evoked potentials in adolescents.

From a sample of 35 adolescents, 17 were chosen who represented extremes of self-reported drug use and delinquent behavior. Three comparison groups were derived: Group 1, n = 7, high drug use/high delinquency; Group 2, n = 4 no drug use/high delinquency; Group 3, n = 6, no drug use/no delinquency. The three groups were similar for age, IQ, race and neighborhood characteristics. Group 1 showed significantly more drug use than Groups 2 and 3; Groups 1 and 2 had comparable levels of delinquency which were significantly greater than Group 3. The subjects performed the auditory oddball task under conditions of low and high background noise. In the high background noise condition, Group 1 had longer latency P300 responses than Groups 2 and 3, while Group 2 had smaller N100 amplitude than Groups 1 and 3. Performance was similar for each group and no group differences occurred in the low background noise condition. The results support and extend previous research on the relationship between attentional and cognitive processes, and delinquent and drug using behaviors.

Self-report vs. laboratory measures of aggression as predictors of substance abuse.

Measures of aggressive behavior, antisocial personality, criminality, and impulsivity were obtained on a sample of 85 drug abusing volunteers for studies at the Addiction Research Center in Baltimore. Measures included the Buss-Durkee Hostility Inventory, Diagnostic Interview Schedule Antisocial Personality Disorder diagnosis, Elliott-Huizinga Lifetime Events Scale, Eysenck's Impulsiveness-Venturesomeness-Empathy scales, and a laboratory measure of aggression patterned after the Buss 'aggression machine'. All of the self-report measures of aggression and antisocial personality were moderately correlated with each other, but did not correlate with the laboratory aggression measure. This laboratory measure, nevertheless, made a significant contribution to the prediction of certain substance abuse diagnoses over and above the contributions of the other measures.

Ethanol decreases responding on behavior maintained under concurrent schedules of both positive reinforcer presentation and avoidance in humans.

Six human volunteers were tested during 15min sessions under the behavioral contingencies of a concurrent fixed-ratio, fixed-ratio schedule of point-gain reinforcement and point-loss avoidance. Completion of each fixed-ratio 50 (FR 50) on the point-gain lever produced 10 points, which were exchanged for money ($.01 per point) after each week of the study. Point losses of 10 points were scheduled to occur during the session on a variable-time 60sec schedule. The total amount of money accumulated was continuously displayed on video monitor. Subjects were exposed to the concurrent schedule until responding under the schedules of point gain and point loss stabilized. After responding had stabilized under these contingencies (4-5 sessions), subjects were tested each day 30min following administration of ethanol, in doses of 0.32, 0.64 or 0.96g/kg, or placebo. Ethanol decreased responding in all subjects and produced dose-related decreases in overall response rates in three subjects. These effects were not related to self-reported current alcohol consumption. Response rates on the reinforcement and the avoidance schedules were both decreased by ethanol. Thus, under these conditions, behavioral effects of ethanol on concurrent FR responding did not depend on the nature of the consequent event.

A critical appraisal of the demand/control model of the psychosocial work environment: epistemological, social, behavioral and class considerations.

During the last decade the demand/control model has emerged as the dominant model to explain the relationship between the psychosocial features of work organization and health. Although originating from the field of occupational social epidemiology, the conceptual and methodological basis of the demand/control model parallel construct based models used in social psychology. Using behavioral and sociological perspectives the current paper discusses the model's limitations. Recommendations regarding incorporation of social levels of analysis, the relationship between self-report and behavior, worker vs expert knowledge, and the generalized effects of stress on mental health are discussed to provide a positive heuristic to the demand/control model.

Social class, assets, organizational control and the prevalence of common groups of psychiatric disorders.

This study provides an update on the association between social class and common types of psychiatric disorder in the US. In addition to usual measures of social class, we provide hypotheses for the expectation that assets and organizational control are associated with specific varieties of psychiatric disorders (mood, anxiety, alcohol and drug use disorders). We analyzed two surveys. The National Comorbidity Survey conducted in 1990-1992 yielded 12-month prevalence rates in a probability sample of 8098 respondents in the 48 contiguous states. The Epidemiologic Catchment Area Follow-up conducted in 1993-1996 provided similar rates among 1920 East Baltimore residents. Analyses of the National Comorbidity Survey showed an inverse association between financial and physical assets and mood, anxiety, alcohol, and drug disorders. The Epidemiologic Catchment Area Followup provided additional evidence for the inverse association between financial and physical assets and anxiety, alcohol and drug disorders. Also in the Epidemiologic Catchment Area, lower level supervisors presented higher rates of depression and anxiety disorders than higher level managers. Inequalities in assets and organizational control, as well as typical measures of social class, are associated with specific psychiatric disorders. These constructs can provide additional explanations for why social inequalities in psychiatric disorders occur.

Psychosocial work environment in human service organizations: a conceptual analysis and development of the demand-control model.

This paper concerns two models that were introduced in two different research domains during the 1970's. The first model regards human service organizations (HSO) as a specific type of organization. The second model, the demand-control model (DC model), concerns the joint effects of job demands and job control on worker health. In the HSO model, there are analyses of the content of jobs, considering the specific characteristics of HSOs, but little is said about the health effects of such work. Those effects stand in focus in the demand-control model. The aim of this paper is to analyze the relevance of the DC model for human service organizations. The paper argues that the object of human service work-the client relation-makes a difference for demand and control in the job. Demand is analyzed into work load, emotional demands and role conflict. Control is divided into administrative control, outcome control, choice of skills, closeness of supervision, control within and over a situation and ideological control. The conclusion is that in applications on HSOs, the basic concepts of the DC model must be developed.

Does organization matter? A multilevel analysis of the demand-control model applied to human services.

The demand-control model (DC model) in occupational epidemiology suggests that health, an individual attribute, is partly determined by work organization, via the interplay of demand and control, job strain. The objective of this study was empirical assessment of the model's tenet of an organizational determination of individual health. An emerging analytic method, multi-level modelling, permits such an assessment. The study encompasses two large Swedish human service organizations. It was based on a nationally representative sample of 291 local organizational units (level 2) with 8296 employees (level 1), a median of 18 employees per unit. 5730 persons (69.1%) completed the questionnaire. Listwise deletion of missing data left a net study base of 4756 individuals in 284 units. Missing data were largely random. Demand and control were measured by standard questions and combined into a job strain index. Two such indices were calculated, one for quantitative demands and one for emotional demands. Individual attributes included age, gender, marital status, having children, social anchorage, and education. There were two dependent variables, self-assessed psychovegetative symptoms (worry, anxiousness, sadness, sleep difficulties, restlessness, and tension) and exhaustion (fatigue, feelings of being used up and overworked), both measured as summative indices. For psychovegetative health, a null model yielded 2.2% level 2 variance, unchanging when individual attributes were included in a random intercepts model. Inclusion of the strain variables rendered level 2 variance non-significant, decreasing level 1 variance by 23% and level 2 variance by 62%. For exhaustion, level 2 variation was 8.3% in the null model and 1.6% in the final model, with strain variables. The strain variables utilized in the DC-model thus draw a substantial part of their variation from the organizational level. It is concluded that the claim of the DC model to rely on organizational factors receives support.
