Social-class inequalities in ill health - the contribution of physical workload

Tutkimuksen aiheita olivat yhteiskuntaluokkien väliset erot sairastavuudessa ja alentuneessa toimintakyvyssä, sekä fyysisen työkuormituksen ja joidenkin muiden työolojen vaikutus sairastavuuteen. Empiirisestä työstä on raportoitu myös neljässä kansainvälisissä tieteellisissä aikakauskirjoissa julkaistussa artikkelissa. Tässä julkaistu yhteenveto sisältää tulosten yhteenvedon lisäksi myös tutkimusta koskevien käsitteellisten ja teoreettisten kysymysten sekä tutkimustradition kriittisen katsauksen. Työn päätavoitteita olivat 1) tutkia fyysisesti kuormittavan työn, ja jossain määrin muiden työolojen osuutta yhteiskuntaluokkien välisiin eroihin sairaudessa ja toimintakyvyn alentuneisuudessa; 2) tutkia työn fyysisen kuormittavuuden, työhön liittyvien vaikutusmahdollisuuksien ja hallinnan (decision latitude), luokka-aseman, iän ja sukupuolen yhteisvaikutuksia heikentyneeseen terveydentilaan; sekä 3) tutkia missä määrin mekaanisten työaltisteiden ja tuki- ja liikuntaelinsairastavuuden välinen yhteys voi selittää yhteiskuntaluokkien välisiä eroja heikentyneessä yleisessä terveydentilassa. Tutkittavat olivat keski-ikäisiä Helsingin kaupungin työntekijöitä. Analyysit perustuivat poikittaisasetelmaan, ja käytetty aineisto oli Helsinki Health Studyn vuosien 2000 ja 2002 välillä kerättyä aineistoa. Analyyseihin käytetyssä aineistossa oli 3740:stä 8002:een tutkittavaa. Tulosten perusteella fyysisillä (sekä fysikaalisilla) työoloilla on merkittävä vaikutus yhteiskuntaluokkien välisiin eroihin yleisessä sairastavuudessa, toimintakyvyn heikentymisessä, tuki- ja liikuntaelinsairastavuudessa sekä itsearvioidussa terveydentilassa. Naisilla lähes puolet heikentyneen toimintakyvyn ja koetun terveydentilan luokkaeroista vaikutti olevan selitettävissä fyysisellä työkuormituksella. Hallintamahdollisuuksien ei havaittu merkittävästi muuttavan fyysisen kuormituksen vaikutusta toimintakykyyn. Fyysisen kuormittavuuden terveysvaikutus voimistui kasvavan iän mukaan enemmän naisilla kuin miehillä. Osa, mutta ei koko fyysisen kuormituksen vaikutus yhteiskuntaluokkien eroihin heikentyneessä terveydessä vaikutti välittyvän tuki- ja liikuntaelinsairastavuuden kautta. Terveys ja sairaus eivät ole yhtenäisiä tiloja, ja siksi monet eri sosiaalisesti ja rakenteellisesti määräytyvät olosuhteet todennäköisesti vaikuttavat yhteiskunnallisten terveyserojen syntymiseen. Fyysis-materiaalisten olojen vaikutusta terveyserojen syntyyn nyky-yhteiskunnassa on mahdollisesti aliarvioitu. Yhteiskuntaluokkien väliset erot fyysis-materiaalisissa olosuhteissa eivät ole kadonneet, ja nämä erot todennäköisesti vaikuttavat terveyserojen syntyyn.

Trends and Explanations for Socioeconomic Differences in Physical Activity

Very limited scientific knowledge exists on the trends and explanations of socioeconomic differences in physical activity among adults. There is a paucity of studies examining whether determinants vary across socioeconomic position and different life stages. This study examines a) how socioeconomic differences in leisure-time and commuting physical activity have changed in Finland from 1978 to 2002 and b) the contribution of childhood socioeconomic position, adolescence sports and exercise, adulthood socioeconomic position, working conditions and other adulthood health behaviours to socioeconomic differences in leisure-time physical activity. This study utilised three population-based datasets collected by the National Institute for Health and Welfare (THL, formerly National Institute for Public Health): the Health Behaviour and Health among the Finnish Adult Population Study from 1978 to 2002 (N=96 105), the National FINRISK Study 2002 and its physical activity sub-study (N= 9 179), and the Health 2000 Study (N=8 028). Survey information was collected by self-administered questionnaires, interviews at home, and measurements made at the study site. The response rates varied from 69 to 89 per cent. Several socioeconomic measures were linked from the national population registers. Based on the results, those with low income were physically inactive during leisure-time and while commuting from 1978 to 2002. Manual worker women, however, were more physically active commuters compared to their counterparts. Parental socioeconomic position contributed directly to adulthood educational differences in leisure-time physical inactivity but also indirectly through adulthood socioeconomic position (occupation, household income) and other unhealthy behaviours (mainly smoking). Among those with low education participation in competitive sports in youth and among those with high education exercise in late adolescence contributed to leisure-time physical activity in adulthood. Long exposure to physically strenuous working conditions in men and current job strain in women contributed to occupational class differences in leisure-time physical activity. Socioeconomic differences in physical activity have remained similar for twenty years in Finland. Educational career seems to have a strong contribution to physical activity. To adopt a lifelong physically active life-style, one should participate in a range of different sports and exercise in adolescence and in youth, have a low exposure to physically and mentally strenuous working conditions in later life and have other healthy behaviours in later life.

Social class, unemployment, and psychological distress

Attempts to explain variation in rates of psychological distress by social class have included reference to social selection, differential exposure to stress, and differential vulnerability arising from inequalities in access to resources. Our analysis draws on data from a national survey of the Republic of Ireland in order to examine these hypotheses. No evidence to support the social selection hypothesis was found. In addressing the issue of differential responsiveness, attention was focused on the interaction between unemployment and social class in their impact on psychological distress. While rather weak support for the hypothesis of differential vulnerability was found among women, our examination of the impact of husband's unemployment provided no evidence leading in this direction. Among men unemployment actually had a stronger impact for men in higher social classes. The major factors leading to social class differences in psychological distress are greater exposure to unemployment and economic deprivation. © 1994 Oxford University Press.

Response of day-to-day home blood pressure variability by antihypertensive drug class after transient ischemic attack or nondisabling stroke.

BACKGROUND AND PURPOSE Visit-to-visit variability in systolic blood pressure (SBP) is associated with an increased risk of stroke and was reduced in randomized trials by calcium channel blockers and diuretics but not by renin-angiotensin system inhibitors. However, time of day effects could not be determined. Day-to-day variability on home BP readings predicts stroke risk and potentially offers a practical method of monitoring response to variability-directed treatment. METHODS SBP mean, maximum, and variability (coefficient of variation=SD/mean) were determined in 500 consecutive transient ischemic attack or minor stroke patients on 1-month home BP monitoring (3 BPs, 3× daily). Hypertension was treated to a standard protocol. Differences in SBP variability from 3 to 10 days before to 8 to 15 days after starting or increasing calcium channel blockers/diuretics versus renin-angiotensin system inhibitors versus both were compared by general linear models, adjusted for risk factors and baseline BP. RESULTS Among 288 eligible interventions, variability in SBP was reduced after increased treatment with calcium channel blockers/diuretics versus both versus renin-angiotensin system inhibitors (-4.0 versus 6.9 versus 7.8%; P=0.015), primarily because of effects on maximum SBP (-4.6 versus -1.0 versus -1.0%; P=0.001), with no differences in effect on mean SBP. Class differences were greatest for early-morning SBP variability (3.6 versus 17.0 versus 38.3; P=0.002) and maximum (-4.8 versus -2.0 versus -0.7; P=0.001), with no effect on midmorning (P=0.29), evening (P=0.65), or diurnal variability (P=0.92). CONCLUSIONS After transient ischemic attack or minor stroke, calcium channel blockers and diuretics reduced variability and maximum home SBP, primarily because of effects on morning readings. Home BP readings enable monitoring of response to SBP variability-directed treatment in patients with recent cerebrovascular events.

Tupakka, luokka ja terveyskäyttäytymisen ongelma

Smoking has decreased significantly over the last few decades, but it still remains one of the most serious public health problems in all Western countries. Smoking has decreased especially in upper socioeconomic groups, and this differentiation is an important factor behind socioeconomic health differentials. The study examines smokers risk perceptions, justifications and the meaning of smoking in different occupational groups. The starting point of the research is that the concept of health behaviour and the individualistic orientation it implies is too narrow a viewpoint with which to understand the current cultural status of smoking and to explain its association with social class. The study utilizes two kinds of data. Internet discussions are used to examine smokers risk perceptions and counter-reactions to current public health discourses. Interviews of smokers and ex-smokers (N=55) from different occupations are utilized to analyse the process of giving up smoking, social class differences in the justifications of smoking and the role of smoking in manual work. The continuing popularity of smoking is not a question of lacking knowledge of or concern about health risks. Even manual workers, in whom smoking is more prevalent, consider smoking a health risk. However, smokers have several ways of dealing with the risk. They can equate it with other health risks confronted in everyday life or question the adequacy of expert knowledge. Smoking can be seen as signifying the ability to make independent decisions and to question authorities. Regardless of the self-acknowledged dependency, smoking can be understood as a choice. This seemingly contradictory viewpoint was central especially for non-manual workers. They emphasized the pleasures and rules of smoking and the management of dependency. In contrast, manual workers did not give positive justifications for their smoking, thus implying the self-evident nature of the habit. Still, smoking functions as a resource in manual work as it increases the autonomy of workers in terms of their daily tasks. At the same time, smoking is attached to other routines and practices at workplaces. The study shows that in order to understand current trends in smoking, differing perceptions of risk and health as well as ways of life and their social and economic determinants need to be taken into account. Focussing on the social contexts and environments in which smoking is most prevalent is necessary in order to explain the current association of smoking with the working class.

Work-life Conflict and Social Inequality in Western Europe

Recent debates on time-use suggest that there is an inverse relationship between time poverty and income poverty (Aguiar and Hurst in Q J Econ C(3):969-1006, 2007), with Hammermesh and Lee (Rev Econ Stat 89(2):374-383, 2007) suggesting much time poverty is 'yuppie kvetch' or 'complaining'. Gershuny (Soc Res Int Q Soc Sci 72(2):287-314, 2005) argues that busyness is the 'badge of honour': being busy is now a positive, privileged position and it is high status people who work long hours and feel busy. Is this also true of work-life conflict? This paper explores the relationship between work-life tension and social inequality, as measured by social class, drawing on evidence from the European Social Survey. To what extent is work-life conflict a problem of the (comparatively) rich and privileged professional/managerial classes, and is this true across European countries? The countries selected offer a range of institutional and policy configurations to maximise variation. Using regression modelling of an index of subjective work-life conflict, we find that in all the countries under study, work-life conflict is higher among professionals than non-professionals. Part of this is explained by the fact that professionals work longer hours and experience more work pressure than other social classes, though the effect remains even after accounting for these factors. While levels of work-life conflict vary across the countries studied, country variation in class differences is modest. We consider other explanations of why professionals report higher work-life conflict and the implications of our findings for debates on social inequality.

Adolescence, immigration et santé mentale : schisme et articulation des discours soignants autour des orientations et des stratégies d'intervention en contexte ethnopsychiatrique

La souffrance psychologique des adolescents fait l'objet d'une attention croissante des pouvoirs publics, des mondes associatifs, et bien sûr des cliniciens et des travailleurs psychosociaux. Pour les adolescents migrants, cette souffrance, aggravée par la fragilité, les malaises et les tensions de l'adolescence, est compliquée par l'appareil de santé publique bureaucratique complexe destiné à traduire dans le langage des soins le malaise des attitudes, des comportements et des tendances qui se dégagent de leur statut de migrant tantôt mal vécu, tantôt réprouvé par leur environnement et leur parcours personnel et familial. Ce mémoire de maîtrise a exploré l'un d'entre eux, celui de la clinique de psychiatrie transculturelle, où l'écoute de ce qui se dit importe tout autant que la traduction et la gestion de ces souffrances. En utilisant une approche anthropologique, j'analyse les discours et les attitudes de dix thérapeutes et les travailleurs sociaux qui interviennent auprès de ces familles. Cette recherche montre que le cadre de gestion sociale et culturelle qui inclut les soignants et les familles, et les ambivalences de jeunes adolescents, ne peut être analysé sans référencer le contexte plus large des différences de classes, d'accès au pouvoir, d'orientations et de bagages culturels affectant à la fois le vécu des adolescents et la manière avec laquelle leurs angoisses seront communiquées et traduites. Dans cette perspective particulière, les paradoxes et les résistances de certains professionnels médicaux et sociaux, dont les positions qu'ils occupent au sein des structures du pouvoir, autrement, pourraient les tenter de s'engager dans des diagnostics faciles liés à la socialisation prétendument difficile de ces adolescences. Au lieu de cela, ils créent des stratégies uniques qui respectent les idiomes officiels encadrant leur autorité médicale et sociale.

Abdellah Taïa et le pays de la tolérance : Une étude sur l’auteur Marocain Abdellah Taïa et ses deux oeuvres L’Armée du salut et Le Jour du Roi.

Ce mémoire a pour but d’étudier comment l’auteur Abdellah Taïa dépeint l’homosexualité et les classes sociales dans la société marocaine, à travers ses oeuvres L’Armée du Salut (2006) et Le Jour du Roi (2010). La méthode utilisée dans le mémoire est l’herméneutique, qui donne la possibilité d’utiliser ses propres interprétations des textes pour les analyser. Les ouvrages étudiés révèlent les difficultés de vivre dans une société religieuse où l’homosexualité est condamnée ainsi qu’interdite par la loi et où l’avenir d’une personne dépend de son statut social.

EU SOU A LUZ DO MUNDO: UM ESTUDO DO SIGNIFICADO DO TERMO LUZ EM JOÃO 9, 1-41

O termo luz se inscreve no encontro das tradições veterotestamentária e grego-romana como uma alternativa a certas necessidades da comunidade joanina: as culturas diferentes dos povos que receberam o evangelho; a diversidade dos problemas que pediam respostas diferentes; a diferença de classes dentro da comunidade; as tomadas de posição discordantes diante da política do império e o conflito entre judeus e cristãos. E é neste ínterim de conflito, tanto interno como externo, um momento doloroso para os dissidentes, porque os prejuízos não eram apenas religiosos, mas provocavam mudanças em todos os âmbitos da vida, que a comunidade joanina procurará alternativa. Por isso, a Narrativa da Cura do Cego de Nascença (Jo 9,1-41) é um espelho para a comunidade. Ela buscará em Jesus a luz de que precisa para continuar. O cego representa a comunidade antes de conhecer a Luz do Mundo. A solidariedade, a fraternidade e o amor mútuos são forças que ajudaram na resistência.(AU)

Stability of Ampelometric Characteristics of Vitis vinifera L. cv. 'Syrah' and 'Sauvignon blanc' Leaves: Impact of Within-vineyard Variability and Pruning Method/Bud Load

Historically, grapevine (Vitis vinifera L.) leaf characterisation has been a driving force in the identification of cultivars. In this study, ampelometric (foliometric) analysis was done on leaf samples collected from hand-pruned, mechanically pruned and minimally pruned ‘Sauvignon blanc’ and ‘Syrah’ vines to estimate the impact of within-vineyard variability and a change in bud load on the stability of leaf properties. The results showed that within-vineyard variability of ampelometric characteristics was high within a cultivar, irrespective of bud load. In terms of the O.I.V. coding system, zero to four class differences were observed between minimum and maximum values of each characteristic. The value of variability of each characteristic was different between the three levels of bud load and the two cultivars. With respect to bud load, the number of shoots per vine had a significant effect on the characteristics of the leaf laminae. Single leaf area and lengths of veins changed significantly for both cultivars, irrespective of treatment, while angle between veins proved to be a stable characteristic. A large number of biometric data can be recorded on a single leaf; the data measured on several leaves, however, are not necessarily unique for a specific cultivar. The leaf characteristics analysed in this study can be divided into two groups according to the response to a change in bud load, i.e. stable (angles between the veins, depths of sinuses) and variable (length of the veins, length of the petiole, single leaf area). The variable characteristics are not recommended to be used in cultivar identification, unless the pruning method/bud load is known.

Do the Messages Matter? An Investigation of Classroom Messages and College Students’ Personal Theories about Education

Students hold a number of personal theories about education that influence motivation and achievement in the classroom: theories about their own abilities, knowledge, and the learning process. Therefore, college instructors have a great interest in helping to develop adaptive personal theories in their students. The current studies investigated whether specific messages that instructors send in college classroom might serve as a mechanism of personal theory development. Across 2 studies, 17 college instructors and 401 students completed surveys assessing their personal theories about education at the beginning and end of college courses. Students and instructors reported hearing and sending many messages in the classroom, including instructor help messages, conciliatory messages, uncertainty in the field messages, differential ability messages and generalized positive and negative feedback. Between-class and within-class differences in message reports were associated with students’ personal theories at the end of their courses, controlling for initial personal theories. Students’ initial personal theories were also related to the messages students reported hearing. The findings demonstrate the utility of assessing non-content messages in college classrooms as potential mechanisms for changing students’ personal theories in college. Implications for research and practice are discussed.
