Asociación de estrés laboral y trastornos hipertensivos en el embarazo

Objetivo: Determinar la prevalencia de trastornos hipertensivos y estrés laboral en las gestantes trabajadoras atendidas en la Clínica Cafam en el mes de noviembre de 2012, y estimar la posible asociación entre estas dos variables. Metodología: Se realizó un estudio de corte transversal. Se incluyeron todas las pacientes gestantes trabajadoras entre 18 y 39 años, con gestación mayor de 20 semanas y feto vivo, sin antecedentes patológicos de importancia, que ingresaron al servicio de hospitalización general y la unidad de cuidado intermedio obstétrico del 1 al 30 de noviembre de 2012 (total de 252). Para medir el nivel de estrés laboral se aplicó una encuesta validada por el Ministerio de Protección social, previo consentimiento informado y se realizó revisión de las historias clínicas para identificar las pacientes con trastornos hipertensivos del embarazo. Resultados: Se incluyeron pacientes de 18 a 39 años encontrando una media de 26.9 años con una desviación estándar de 5,08. 208 pacientes (82.5%) tenían entre 36 y 40 semanas de gestación, 123 maternas cursaban su primera gestación (48.8%) y, la mayoría tienen una relación estable. Respecto al nivel educativo la formación técnica y el bachillerato fueron los más encontrados (38.49% y 35.32% respectivamente). 102 gestantes (40.48%) desempeñan cargos de auxiliar o asistente seguidos de los trabajos operativos en un 30.56% (77 personas). De las 252 pacientes del estudio, 22 maternas tenían hipertensión gestacional, 28 preeclampsia y 1 síndrome HELLP para un total de 20.24% de gestantes con patología. Hay un alto porcentaje de estrés laboral en la población estudiada (40.08%). Al realizar el análisis de los datos se encontró que la probabilidad que tienen las pacientes con algún trastorno hipertensivo de tener estrés laboral es mayor que la de las pacientes que no presentan patología (OR 1.43 con IC 95% de 0.8 a 2.55). Conclusiones. El estrés laboral tiene una alta prevalencia en la población gestante trabajadora y los resultados sugieren que puede ser uno de los factores contribuyentes en la aparición de trastornos hipertensivos en el embarazo.

La prevención de riesgos psicosociales en la empresa

Este documento se constituye en el resultado de una investigación que permite de una u otra forma ampliar los conocimientos frente a las diversas implicaciones que tiene el riesgo psicosocial no solo a nivel organizacional, sino también en el factor humano, ya que es un área poco explorada pero con grandes consecuencias ocasionalmente nefastas para la organización y el trabajador, apreciándose como una categoría de estudio para los profesionales de la prevención de la salud y seguridad en el trabajo. El estudio cuenta con el análisis de información escrita, información empírica de expertos tanto del área de salud mental como de riesgo psicosocial, y testimonios de individuos con algún tipo de experiencia a nivel empresarial que denote el riesgo psicosocial, este en complemento con la salud mental.

A gender approach to work ability and its relationship to professional and domestic work hours among nursing personnel

The association between working hours and work ability was examined in a cross-sectional study of male (N = 156) and female (N = 1092) nurses in three public hospitals. Working hours were considered in terms of their professional and domestic hours per week and their combined impact; total work load. Logistic regression analysis showed a significant association between total work load and inadequate work ability index (WAI) for females only. Females reported a higher proportion of inadequate WAI, fewer professional work hours but longer domestic work hours. There were no significant differences in total work load by gender. The combination of professional and domestic work hours in females seemed to best explain their lower work ability. The findings suggest that investigations into female well-being need to consider their total work load. Our male sample may have lacked sufficient power to detect a relationship between working hours and work ability. (c) 2008 Elsevier Ltd. All rights reserved.

Women's subjective and objective health over time : the role of psychosocial conditions and physiological stress responses

Today, health problems are likely to have a complex and multifactorial etiology, whereby psychosocial factors interact with behaviour and bodily responses. Women generally report more health problems than men. The present thesis concerns the development of women’s health from a subjective and objective perspective, as related to psychosocial living conditions and physiological stress responses. Both cross-sectional and longitudinal studies were carried out on a representative sample of women. Data analysis was based on a holistic person-oriented approach as well as a variable approach. In Study I, the women’s self-reported symptoms and diseases as well as self-rated general health status were compared to physician-rated health problems and ratings of the general health of the women, based on medical examinations. The findings showed that physicians rated twice as many women as having poor health compared to the ratings of the women themselves. Moreover, the symptom ”a sense of powerlessness” had the highest predictive power for self-rated general health. Study II investigated individual and structural stability in symptom profiles between adolescence and middle-age as related to pubertal timing. There was individual stability in symptom reporting for nearly thirty years, although the effect of pubertal timing on symptom reporting did not extend into middle-age. Study III explored the longitudinal and current influence of socioeconomic and psychosocial factors on women’s self-reported health. Contemporary factors such as job strain, low income, financial worries, and double exposure in terms of high job strain and heavy domestic responsibilities increased the risk for poor self-reported health in middle-aged women. In Study IV, the association between self-reported symptoms and physiological stress responses was investigated. Results revealed that higher levels of medically unexplained symptoms were related to higher levels of cortisol, cholesterol, and heart rate. The empirical findings are discussed in relation to existing models of stress and health, such as the demand-control model, the allostatic load model, the biopsychosocial model, and the multiple role hypothesis. It was concluded that women’s health problems could be reduced if their overall life circumstances were improved. The practical implications of this might include a redesign of the labour market giving women more influence and control over their lives, both at and away from work.

Stress and hemostasis: an update

Numerous naturalistic, experimental, and mechanistic studies strongly support the notion that-as part of fight-or-flight response-hemostatic responses to acute psychosocial stress result in net hypercoagulability, which would protect a healthy organism from bleeding in case of injury. Sociodemographic factors, mental states, and comorbidities are important modulators of the acute prothrombotic stress response. In patients with atherosclerosis, exaggerated and prolonged stress-hypercoagulability might accelerate coronary thrombus growth following plaque rupture. Against a background risk from acquired prothrombotic conditions and inherited thrombophilia, acute stress also might trigger venous thromboembolic events. Chronic stressors such as job strain, dementia caregiving, and posttraumatic stress disorder as well as psychological distress from depressive and anxiety symptoms elicit a chronic low-grade hypercoagulable state that is no longer viewed as physiological but might impair vascular health. Through activation of the sympathetic nervous system, higher order cognitive processes and corticolimbic brain areas shape the acute prothrombotic stress response. Hypothalamic-pituitary-adrenal axis and autonomic dysfunction, including vagal withdrawal, are important regulators of hemostatic activity with longer lasting stress. Randomized placebo-controlled trials suggest that several cardiovascular drugs attenuate the acute prothrombotic stress response. Behavioral interventions and psychotropic medications might mitigate chronic low-grade hypercoagulability in stressed individuals, but further studies are clearly needed. Restoring normal hemostatic function with biobehavioral interventions bears the potential to ultimately decrease the risk of thrombotic diseases.

Prevalence of exposure to occupational risks during preganancy in Spain

Objectives. We describe reported exposures to main categories of occupational agents and conditions in Spanish pregnant workers. Methods. Women were recruited at 12th week of pregnancy from main public gynaecological consults to be included in the INMA Spanish cohorts study (n = 2,058). Through personal interviews with structured questionnaires, information on working situation and working conditions during pregnancy was obtained. Results. Fifty percent of the women reported frequent exposure to physical load (standing, heavy lifting) and 45 % reported exposure to three or more indicators of job strain. Exposure to at least one physical agent (noise, vibrations, etc.) affected 25 % of the women. Exposure to chemicals was reported by 20 % of the women, mostly including solvents and cleaning products. Eight percent of the women worked at night shifts. Job strain was more prevalent in office workers and industrial operators. Industrial workers showed the highest prevalence of exposure to chemical and physical pollutants. Conclusions. Our data suggest that working conditions of pregnant women may need increased control in Spain.

Spontaneous Abortions and Shift Work in a Cohort of Nurses in Norway

Background: An association between spontaneous abortions and shift work has been suggested, but present research results are conflicting. The aim of the study is to evaluate the relationship between spontaneous abortions among nurses, shift schedules, and nights worked. Methods: This is a longitudinal study where we identified 914 females from a cohort of nurses in Norway who had worked the same type of shift schedule 2008-2010; either permanent day shift, three-shift rotation or permanent night shift. Information on age, work and life-style factors, as well as spontaneous abortions during lifetime and the past three years (2008-2010) was obtained by annual questionnaires. Results: A higher prevalence of experienced spontaneous abortions before study start (2008) was found among nurses working permanent night shift compared to other nurses. In a linear regression analysis, a risk of 1.3 was found for experienced spontaneous abortions before study start among permanent night shift nurses, with day shift as reference, when adjusting for age, smoking, caffeine and job strain, but the finding was not statistical significant (95 per cent confidence interval 0.8-2.1). Permanent night shift workers had a risk of 1.5 experiencing spontaneous abortions in 2008-2010 compared to day shift nurses, although not statistical significant (95 per cent confidence interval 0.7-3.5). The number of night shifts the past three years was not associated with experiencing spontaneous abortions 2008-2010, but associated with a reduced risk of experiencing spontaneous abortions during lifetime. The results must be interpreted in the light of a possible selection bias; both selections into the occupation of nursing and into the different shift types of the more healthy persons may have occurred in this population. Conclusion: No significant increased risk of spontaneous abortion among permanent night shift nurses compared to day-time nurses was found in this study, and no association was found between spontaneous abortions and the number of worked night shifts.

Perceived occupational stress in nurses working in Ireland

Background: This study examines perceived stress and its potential causal factors in nurses. Stress has been seen as a routine and accepted part of the healthcare worker’s role. The lack of research on stress in nurses in Ireland motivated this study. Aims: The aims of this study are to examine the level of stress experienced by nurses working in an Irish teaching hospital, and investigate differences in perceived stress levels by ward area and associations with work characteristics. Method: A cross-sectional study design was employed, with a two-stage cluster sampling process. A self-administered questionnaire was used to collect the data and nurses were investigated across ten different wards using the Nursing Stress Scale and the Demand Control Support Scales. Results: The response rate was 62%. Using outpatients as a reference ward, perceived stress levels were found to be significantly higher in the medical ward, accident and emergency, intensive care unit and paediatric wards (p<0.05). There was no significant difference between the wards with regard to job strain, however, differences did occur with levels of support; the day unit and paediatric ward reporting the lowest level of supervisor support (p<0.01). A significant association was seen between the wards and perceived stress even after adjustment (p<0.05). Conclusion: The findings suggest that perceived stress does vary within different work areas in the same hospital. Work factors, such as demand and support are important with regard to perceived stress. Job control was not found to play an important role.

Effets des contraintes psychosociales au travail sur la détresse psychologique et les absences médicalement certifiées pour problèmes de santé mentale: une étude prospective de 5 ans

Contexte : Les effets cumulés des contraintes psychosociales du modèle déséquilibre efforts-reconnaissance (DER) sur la santé mentale sont peu connus. Aussi, peu d’études ont évalué les effets du DER sur des indicateurs objectifs de problèmes de santé mentale (PSM). Enfin, aucune étude prospective antérieure n’a évalué l’effet combiné des contraintes psychosociales du DER et du modèle demande-latitude (DL) et sur les PSM médicalement certifiés. La présente thèse vise à combler ces limites. Objectifs : 1) Mesurer l’effet de l’exposition cumulée au déséquilibre efforts-reconnaissance sur la prévalence de la détresse psychologique sur une période de cinq ans; 2) Mesurer l’effet du déséquilibre efforts-reconnaissance sur l’incidence des absences médicalement certifiées pour PSM sur une période de cinq ans; 3) Évaluer l’effet indépendant et l’effet combiné des contraintes psychosociales des modèles Demande-Latitude et Déséquilibre Efforts-Reconnaissance sur l’incidence des absences médicalement certifiées pour PSM sur une période de cinq ans. Méthodes : La cohorte était constituée de plus de 2000 hommes et femmes occupant des emplois de cols blancs. La collecte des données a été réalisée à trois reprises avec une moyenne de suivi de cinq ans. À chaque temps, les contraintes psychosociales et la détresse psychologique ont été mesurées à l’aide d’instruments validés. Les absences médicalement certifiées pour PSM ont été récoltées à partir des fichiers administratifs des employeurs. Les PSM ont été modélisés à l’aide des régressions log-binomiale et de Cox. Les analyses ont été réalisées séparément chez les hommes et les femmes, en ajustant pour les principaux facteurs de confusion. Résultats : Chez les hommes et les femmes, une exposition chronique au DER sur trois ans était associée à une prévalence plus élevée de la détresse psychologique. Les effets observés à trois ans ont persisté à cinq ans chez les hommes (Rapport de prévalence (RP)=1,91 (1,20–3,04)) et les femmes (RP=2,48 (1,97–3,11)). Ces effets étaient de plus grande amplitude que ceux observés en utilisant l’exposition initiale à l’entrée dans l’étude (de +0,30 à +0,94). Par ailleurs, les hommes et les femmes exposés au DER présentaient un risque plus élevé d’absences médicalement certifiées pour PSM (Risque relatif (RR)=1,38 (1,08–1,76)), comparés aux travailleurs non-exposés. La faible reconnaissance au travail était associée à un risque important d’absences pour PSM chez les hommes (RR=3,04 (1,46–6,33)) mais pas chez les femmes (RR=1,24 (0,90–1,72)). Chez les femmes uniquement, un effet indépendant du « job strain » (RR=1,50 (1,12–2,07)) et du DER (RR=1,34 (0,98–1,84)), ainsi qu’un effet de l’exposition combinée au « job strain » (demande psychologique élevée et faible latitude décisionnelle) et au DER (RR=1,97 (1,40–2,78)) sur le risque d’absences médicalement certifiées pour PSM ont également été observés. Conclusion : Les résultats de cette thèse supportent l’effet délétère de l’exposition au DER sur la prévalence de la détresse psychologique et sur le risque d’absences médicalement certifiées pour PSM chez les hommes et les femmes. Chez les hommes et les femmes, l’exposition cumulée au DER était associée à une prévalence élevée de la détresse psychologique à trois ans et à cinq ans. De plus, les contraintes psychosociales du DER ont été associées aux absences médicalement certifiés pour PSM. Chez les femmes particulièrement, un effet combiné du « job strain » et du DER était associé à un risque plus élevé d’absences médicalement certifiées pour PSM, que l’exposition à un seul des deux facteurs. Ces résultats suggèrent que la réduction des contraintes psychosociales au travail pourrait contribuer à réduire l’incidence des PSM, incluant les absences médicalement certifiées pour PSM.

Work stress, smoking status and smoking intensity: an observational study of 46 190 employees

Study objective: To examine the relationship between work stress, as indicated by the job strain model and the effort-reward imbalance model, and smoking. Setting: Ten municipalities and 21 hospitals in Finland. Design and Participants: Binary logistic regression models for the prevalence of smoking were related to survey responses of 37 309 female and 8881 male Finnish public sector employees aged 17-65. Separate multinomial logistic regression models were calculated for smoking intensity for 8130 smokers. In addition, binary logistic regression models for ex-smoking were fitted among 16 277 former and current smokers. In all analyses, adjustments were made for age, basic education, occupational status, type of employment and marital status. Main results: Respondents with high effort-reward imbalance or lower rewards were more likely to be smokers. Among smokers, an increased likelihood of higher intensity of smoking was associated with higher job strain and higher effort-reward imbalance and their components such as low job control and low rewards. Smoking intensity was also higher in active jobs in women, in passive jobs and among employees with low effort expenditure. Among former and current smokers, high job strain, high effort-reward imbalance and high job demands were associated with a higher likelihood of being a current smoker. Lower effort was associated with a higher likelihood of ex-smoking. Conclusions: This evidence suggests an association between work stress and smoking and implies that smoking cessation programs may benefit from the taking into account the modification of stressful features of work environment. Key words: effort-reward imbalance; job strain; smoking. Abbreviations: OR, odds ratio; CI, confidence interval; SES, socioeconomic status

Organisational justice and smoking: the Finnish Public Sector Study

Study Objective: To examine the extent to which justice of decision-making procedures and interpersonal relations is associated with smoking. Setting: Ten municipalities and 21 hospitals in Finland. Design and Participants: Cross-sectional data derived from the Finnish Public Sector Study were analysed with logistic regression analysis models with generalized estimating equations. Analyses of smoking status were based on 34 021 employees. Separate models for heavy smoking (>20 cigarettes per day) were calculated for 6295 current smokers. Main results: After adjustment for age, education, socio-economic position, marital status, job contract, and negative affectivity, smokers who reported low procedural justice were about 1.4 times more likely to smoke >20 cigarettes per day compared with their counterparts with high justice. In a similar way, after adjustments, low justice in interpersonal treatment was significantly associated with an elevated prevalence of heavy smoking (odds ratio (OR) = 1.35, 95% CI = 1.03 to 1.77 for men and OR = 1.41, 95% CI = 1.09 to 1.83 for women). Further adjustment for job strain and effort-reward imbalance had little effect on these results. There were no associations between justice components and smoking status or ex-smoking. Conclusions: The extent to which employees are treated with justice in the workplace seems to be associated with smoking intensity independently of established stressors at work.

Low organisational justice and heavy drinking: a prospective cohort study

Objectives: To investigate whether low perceived organisational injustice predicts heavy drinking among employees. Methods: Data from the prospective occupational cohort study, the 10-Town Study, related to 15 290 Finnish public sector local government employees nested in 2432 work units, were used. Non-drinkers were excluded. Procedural, interactional and total organisational justice, heavy drinking (>=210 g of absolute alcohol per week) and other psychosocial factors were determined by means of questionnaire in 2000-2001 (phase 1) and 2004 (phase 2). Multilevel logistic regression analyses taking into account for the hierarchical structure of the data were conducted and adjustments were made for sex, age, socio-economic position, marital status, baseline heavy drinking, psychological distress and other psychosocial risk factors such as job strain and effort/reward imbalance. Results: After adjustments, participants who reported low procedural justice at phase 1 were about 1.2 times more likely to be heavy drinkers at phase 2 compared with their counterparts with high justice. Low perceived justice in interpersonal treatment and low perceived total organisational justice were associated with an elevated prevalence of heavy drinking only in the socio-demographics adjusted model. Conclusions: This is the first longitudinal study to show that low procedural justice is weakly associated with an increased likelihood of heavy drinking.

Effort-reward imbalance and sedentary lifestyle: an observational study in a large occupational cohort

Objectives: To investigate the association between effort-reward imbalance (ERI) at work and sedentary lifestyle. Methods: Cross-sectional data from the ongoing Finnish Public Sector Study related to 30 433 women and 7718 men aged 17-64 were used (n = 35 918 after exclusion of participants with missing values in covariates). From the responses to a questionnaire, an aggregated mean score for ERI in a work unit was assigned to each participant. The outcome was sedentary lifestyle defined as <2.00 metabolic equivalent task (MET) hours/day. Logistic regression with generalized estimating equations was used as an analysis method to include both individual and work unit level predictors in the models. Adjustments were made for age, marital status, occupational status, job contract, smoking, and heavy drinking. Results: Twenty five percent of women and 27% of men had a sedentary lifestyle. High individual level ERI was associated with a higher likelihood of sedentary lifestyle both among women (odds ratio (OR) = 1.08, 95% CI 1.01 to 1.16) and men (OR = 1.17, 95% CI 1.02 to 1.33). These associations were not explained by relevant confounders and they were also independent of work unit level job strain measured as a ratio of job demands and control. Conclusions: A mismatch between high occupational effort spent and low reward received in turn seems to be associated with an elevated risk of sedentary lifestyle, although this association is relatively weak.

Demanda y control de la tarea y presencia de síntomas de estrés y osteo-musculares en personal de una institución hospitalaria de IV nivel, Bogotá, 2016.

El ejercicio de labores asistenciales en el personal de la salud, las largas horas de trabajo y la responsabilidad en la ejecución de sus tareas, llevan consigo la exposición a riesgos psicosociales; que de no ser debidamente controlados pueden llevar al individuo a generar respuestas inadecuadas a nivel cognitivo, emocional e intelectual, las cuales se manifiestan en algunos casos con la aparición de sintomatología osteomuscular y/o asociada al estrés. OBJETIVO Identificar la relación entre las demandas de la tarea, el control sobre las mismas y la presencia e intensidad de síntomas de estrés y osteo-musculares en médicos, especialistas y personal de enfermería de una institución hospitalaria de IV nivel en Bogotá. Métodos Estudio de corte transversal en una muestra de 100 profesionales de la salud. Se utilizaron tres instrumentos: cuestionario Nórdico para la detección y análisis de síntomas músculo esqueléticos, cuestionario Karasek para identificar la percepción del trabajo y la relación del entorno profesional y el cuestionario de Estrés del Ministerio de la Protección Social validado para la población colombiana. Se obtuvo previa autorización del Comité de Investigaciones y Comité de Ética del Hospital. El análisis estadístico se realizó con el IBM SPSS Statistics versión 2.0 Resultados Se observó que los síntomas osteomusculares con mayor prevalencia estuvieron relacionados con afectaciones en espalda 43% y cuello 36%; no se observan diferencias estadísticamente significativas entre los distintos profesionales. En cuanto a presencia de sintomatología asociada al estrés, la mayor prevalencia se presentó en síntomas osteomusculares en cuello y espalda en el 84% de los casos, dolor de cabeza en el 74%, trastornos del sueño y cansancio en el 64% y percepción de sobrecarga laboral en el 63%. Para el análisis de prevalencia de los factores psicosociales laborales se utilizó la clasificación de la combinación de altas o bajas demandas y alto o bajo control, el resultado de estos teniendo en cuenta el modelo Demanda-control fue la siguiente: trabajo de alta tensión 34%; trabajo activo 40%; trabajo aburrido 13% y trabajo pasivo 13%. Se encontró una asociación entre la sintomatología y las variables toma de decisiones en médicos especialistas (OR 3,12; IC 95%: 2,80 – 3,49) lo que ratifica que este tipo de profesional tiene una mayor libertad para generar decisiones en su actuar médico y control sobre la tarea para especialistas (OR 3,23; IC 95%: 2,82 – 3,70) y enfermeros jefes (OR 3,36; IC 95%: 2,91 – 3,89); lo que permite inferir que cada uno de estos profesionales posee las herramientas para asumir las exigencias y dar respuesta a los distintos aspectos que están ligados a la tarea. Conclusiones: La presencia de síntomas osteo musculares en zonas como cuello y espalda son propios de la actividad del personal de la salud y se asocia a las posturas inadecuadas y el puesto de trabajo, así como al estrés. En cuanto a la sintomatología asociada al estrés se ratifica la presencia de sintomatología osteo muscular (cuello y espalda), como manifestaciones asociadas al cansancio, trastornos del sueño, sobrecarga laboral, dolor de cabeza y en menor porcentaje dificultades para relacionarse con otros. Respecto a los factores de riesgo psicosocial, se observó que el trabajo activo es la condición predominante en el personal de la salud, pero se observa además que un porcentaje importante experimenta episodios de tensión laboral, asociados a condiciones propias de las demandas psicológicas y el control sobre la tarea. Por lo anterior, se deben establecer acciones encaminadas a favorecer espacios saludables, y programas tendientes a la mejora de las condiciones de tal manera que disminuya la presencia de sintomatología osteomuscular y/o sintomatología derivada del estrés.
