Socioeconomic inequalities in health in the working population: the contribution of working conditions.
(1/5512)
BACKGROUND: The aim was to study the impact of different categories of working conditions on the association between occupational class and self-reported health in the working population. METHODS: Data were collected through a postal survey conducted in 1991 among inhabitants of 18 municipalities in the southeastern Netherlands. Data concerned 4521 working men and 2411 working women and included current occupational class (seven classes), working conditions (physical working conditions, job control, job demands, social support at work), perceived general health (very good or good versus less than good) and demographic confounders. Data were analysed with logistic regression techniques. RESULTS: For both men and women we observed a higher odds ratio for a less than good perceived general health in the lower occupational classes (adjusted for confounders). The odds of a less than good perceived general health was larger among people reporting more hazardous physical working conditions, lower job control, lower social support at work and among those in the highest category of job demands. Results were similar for men and women. Men and women in the lower occupational classes reported more hazardous physical working conditions and lower job control as compared to those in higher occupational classes. High job demands were more often reported in the higher occupational classes, while social support at work was not clearly related to occupational class. When physical working conditions and job control were added simultaneously to a model with occupational class and confounders, the odds ratios for occupational classes were reduced substantially. For men, the per cent change in the odds ratios for the occupational classes ranged between 35% and 83%, and for women between 35% and 46%. CONCLUSIONS: A substantial part of the association between occupational class and a less than good perceived general health in the working population could be attributed to a differential distribution of hazardous physical working conditions and a low job control across occupational classes. This suggests that interventions aimed at improving these working conditions might result in a reduction of socioeconomic inequalities in health in the working population. (+info)
Socioeconomic inequalities and disability pension in middle-aged men.
(2/5512)
BACKGROUND: The issue of inequalities in health has generated much discussion and socioeconomic status is considered an important variable in studies of health. It is frequently used in epidemiological studies, either as a possible risk factor or a confounder and the aim of this study was to analyse the relation between socioeconomic status and risk of disability pension. METHODS: Five complete birth year cohorts of middle-aged male residents in Malmo were invited to a health survey and 5782 with complete data constituted the cohort in this prospective study. Each subject was followed for approximately 11 years and nationwide Swedish data registers were used for surveillance. RESULTS: Among the 715 men (12%), granted disability pension during follow-up, three groups were distinguished. The cumulative incidence of disability pension among blue collar workers was 17% and among lower and higher level white collar workers, 11% and 6% respectively. With simultaneous adjustment for biological risk factors and job conditions, the relative risk for being granted a disability pension (using higher level white collar workers as reference) was 2.5 among blue collar workers and 1.6 among lower level white collar workers. CONCLUSIONS: Socioeconomic status, as defined by occupation, is a risk factor for being granted disability pension even after adjusting for work conditions and other risk factors for disease. (+info)
Permanent work incapacity, mortality and survival without work incapacity among occupations and social classes: a cohort study of ageing men in Geneva.
(3/5512)
BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: Medically-ascertained permanent work incapacity and survival without work incapacity have shown considerably greater socioeconomic differentials than the mortality differentials. (+info)
Socioeconomic differences in childhood consultation rates in general practice in England and Wales: prospective cohort study.
(4/5512)
OBJECTIVE: To establish how consultation rates in children for episodes of illness, preventive activities, and home visits vary by social class. DESIGN: Analysis of prospectively collected data from the fourth national survey of morbidity in general practice, carried out between September 1991 and August 1992. SETTING: 60 general practices in England and Wales. SUBJECTS: 106 102 children aged 0 to 15 years registered with the participating practices. MAIN OUTCOME MEASURES: Mean overall consultation rates for any reason, illness by severity of underlying disease, preventive episodes, home visits, and specific diagnostic category (infections, asthma, and injuries). RESULTS: Overall consultation rates increased from registrar general's social classes I-II to classes IV-V in a linear pattern (for IV-V v I-II rate ratio 1.18; 95% confidence interval 1.14 to 1. 22). Children from social classes IV-V consulted more frequently than children from classes I-II for illnesses (rate ratio 1.23; 1.15 to 1.30), including infections, asthma, and injuries and poisonings. They also had significantly higher consultation rates for minor, moderate, and serious illnesses and higher home visiting rates (rate ratio 2.00; 1.81 to 2.18). Consultations for preventive activities were lower in children from social classes IV-V than in children from social classes I-II (rate ratio 0.95; 0.86 to 1.05). CONCLUSIONS: Childhood consultation rates for episodes of illness increase from social classes I-II through to classes IV-V. The findings on severity of underlying illness suggest the health of children from lower social classes is worse than that of children from higher social classes. These results reinforce the need to identify and target children for preventive health care in their socioeconomic context. (+info)
The impact of genetic counselling on risk perception and mental health in women with a family history of breast cancer.
(5/5512)
The present study investigated: (1) perception of genetic risk and, (2) the psychological effects of genetic counselling in women with a family history of breast cancer. Using a prospective design, with assessment pre- and post-genetic counselling at clinics and by postal follow-up at 1, 6 and 12 months, attenders at four South London genetic clinics were assessed. Participants included 282 women with a family history of breast cancer. Outcome was measured in terms of mental health, cancer-specific distress and risk perception. High levels of cancer-specific distress were found pre-genetic counselling, with 28% of participants reporting that they worried about breast cancer 'frequently or constantly' and 18% that worry about breast cancer was 'a severe or definite problem'. Following genetic counselling, levels of cancer-specific distress were unchanged. General mental health remained unchanged over time (33% psychiatric cases detected pre-genetic counselling, 27% at 12 months after genetic counselling). Prior to their genetics consultation, participants showed poor knowledge of their lifetime risk of breast cancer since there was no association between their perceived lifetime risk (when they were asked to express this as a 1 in x odds ratio) and their actual risk, when the latter was calculated by the geneticist at the clinic using the CASH model. In contrast, women were more accurate about their risk of breast cancer pre-genetic counselling when this was assessed in broad categorical terms (i.e. very much lower/very much higher than the average woman) with a significant association between this rating and the subsequently calculated CASH risk figure (P = 0.001). Genetic counselling produced a modest shift in the accuracy of perceived lifetime risk, expressed as an odds ratio, which was maintained at 12 months' follow-up. A significant minority failed to benefit from genetic counselling; 77 women continued to over-estimate their risk and maintain high levels of cancer-related worry. Most clinic attenders were inaccurate in their estimates of the population risk of breast cancer with only 24% able to give the correct figure prior to genetic counselling and 36% over-estimating this risk. There was some improvement following genetic counselling with 62% able to give the correct figure, but this information was poorly retained and this figure had dropped to 34% by the 1-year follow-up. The study showed that women attending for genetic counselling are worried about breast cancer, with 34% indicating that they had initiated the referral to the genetic clinic themselves. This anxiety is not alleviated by genetic counselling, although women reported that it was less of a problem at follow-up. Women who continue to over-estimate their risk and worry about breast cancer are likely to go on seeking unnecessary screening if they are not reassured. (+info)
Socioeconomic status and determinants of hemostatic function in healthy women.
(6/5512)
Hemostatic factors are reported to be associated with coronary heart disease (CHD). Socioeconomic status (SES) is 1 of the determinants of the hemostatic profile, but the factors underlying this association are not well known. Our aim was to examine determinants of the socioeconomic differences in hemostatic profile. Between 1991 and 1994, we studied 300 healthy women, aged 30 to 65 years, who were representative of women living in the greater Stockholm area. Fibrinogen, factor VII mass concentration (FVII:Ag), activated factor VII (FVIIa), von Willebrand factor (vWF), and plasminogen activator inhibitor-1 (PAI-1) were measured. Educational attainment was used as a measure of SES. Low educational level and an unfavorable hemostatic profile were both associated with older age, unhealthful life style, psychosocial stress, atherogenic biochemical factors, and hypertension. Levels of hemostatic factors increased with lower educational attainment. Independently of age, the differences between the lowest (mandatory) and highest (college/university) education in FVII:Ag levels were 41 microg/L (95% confidence interval [CI], 15 to 66 microg/L, P=0.001), 0.26 g/L (95% CI, 0.10 to 0.42 g/L, P=0.001) in fibrinogen levels, and 0.11 U/mL (95% CI, 0.09 to 0.12 U/mL, P=0.03) in levels of vWF. The corresponding differences in FVIIa and PAI-1 were not statistically significant. With further adjustment for menopausal status, family history of CHD, marital status, psychosocial stress, lifestyle patterns, biochemical factors, and hypertension, statistically significant differences between mandatory and college/university education were observed in FVII:Ag (difference=34 microg/L; 95% CI, 2 to 65 microg/L, P=0.05) but not in fibrinogen (difference=0.03 g/L; 95% CI, -0.13 to 0.19 g/L, P=0.92) or in vWF (difference=0.06 U/mL; 95% CI, -0.10 to 0.22 U/mL, P=0.45). An educational gradient was most consistent and statistically significant for FVII:Ag, fibrinogen, and vWF. Age, psychosocial stress, unhealthful life style, atherogenic biochemical factors, and hypertension mediated the association of low educational level with elevated levels of fibrinogen and vWF. Psychosocial stress and unhealthful life style were the most important contributing factors. There was an independent association between education and FVII:Ag, which could not be explained by any of these factors. (+info)
Alcohol consumption, alcohol-related problems, problem drinking, and socioeconomic status.
(7/5512)
In general, a lower socioeconomic status (SES) is related to a lower health status, more health problems, and a shorter life expectancy. Although causal relations between SES and health are unclear, lifestyle factors play an intermediate role. The purpose of the present study was to obtain more insight into the relation between SES, alcohol consumption, alcohol-related problems, and problem drinking, through a general population survey among 8000 people in Rotterdam. Odds ratios were calculated using educational level as independent, and alcohol consumption, alcohol-related problems, and problem drinking as dependent variables. Abstinence decreased significantly by increasing educational level for both sexes. For men, excessive drinking, and notably very excessive drinking, was more prevalent in the lowest educational group. For women, no significant relation between educational level and prevalence of excessive drinking was found. After controlling for differences in drinking behaviour, among men the prevalence of 'psychological dependence' and 'social problems' was higher in intermediate educational groups, whereas prevalence of 'drunkenness' was lower in intermediate educational groups. For women, a negative relation was found between educational level and 'psychological dependence'; prevalence of 'symptomatic drinking' was higher in the lowest educational group. Prevalence of problem drinking was not related to educational level in either sex. It is concluded that differences exist between educational levels with respect to abstinence, but only limited differences were found with respect to excessive drinking. Furthermore, there is evidence for higher prevalences of alcohol-related problems in lower educational levels, after controlling for differences in drinking behaviour, in both sexes. (+info)
Family factors affecting child development.
(8/5512)
In a large, geographically defined population of children a number of family factors in addition to social class, determined by the father's occupation, were recorded by health visitors and school nurses with routine responsibility for these children. The quality of the children in normal schools was assessed in terms of nonverbal IQ and height at the ages of 5 and 10 years, and of behavior as reported by the teacher at the age of 10 years. By analysis of variance the sum of the independent effects of the other family factors greatly outweighed that of occupational social class, except in the case of the IQ at 10 years. The most important of the other family factors was the quality of the mother's care of her child during the first 3 years of life. (+info)
