Do socioeconomic disadvantages persist into old age? Self-reported morbidity in a 29-year follow-up of the Whitehall Study.
(17/444)
OBJECTIVES: This study examined (1) the relation of employment grade in middle age to self-reported poor health and functional limitations in old age and (2) whether socioeconomic status at approximately the time of retirement modifies health differentials in old age. METHODS: Survivors of the Whitehall Study cohort of men were resurveyed. Respondents were aged 40 to 69 years when they were originally screened in 1967 to 1970. RESULTS: Compared with senior administrators, men in clerical or manual (low-grade) jobs in middle age had quadruple the odds of poor physical performance in old age, triple the odds of poor general health, and double the odds of poor mental health and disability. At most, 20% of these differences were explained by baseline health or risk factors. Men who moved from low to middle grades before retirement were less likely than those who remained in low grades to have poor mental health. CONCLUSIONS: Socioeconomic status in middle age and at approximately retirement age is associated with morbidity in old age. (+info)
Cross sectional and longitudinal study on selenium, glutathione peroxidase, smoking, and occupational exposure in coal miners.
(18/444)
OBJECTIVES: To understand the variations of selenium (Se) concentration relative to changes in occupational exposure to coal dust, taking into account age and changes in smoking habits in miners surveyed twice, in 1990 and 1994. To better understand the relation of Se concentration with glutathione peroxidase activities (GSH-Px) in these miners. METHODS: In 1994, blood samples were obtained from active (n=131) and retired (n=40) miners without coal worker's pneumoconiosis, in whom Se concentration was available at both surveys and in whom International Labour Organisation (ILO) profusion grade had not been changed. Active miners were exposed to high dust concentrations (n=48) or low dust concentrations (n=83). Miners were classified into three subgroups according to their estimated cumulative exposure to dust, and into three subgroups according to their smoking habits. RESULTS: Selenium concentration and GSH-Px activities were significantly lower in active than in retired miners (Se adjusted means: 62.6 v 72.2 ng/ml p=0.01). Moreover, Se concentration was lower in miners exposed to high compared with those exposed to low dust concentrations (adjusted means: 59.4 v 65.8). In miners exposed to high dust concentrations, Se concentration was significantly lower whereas erythrocyte GSH-Px activity was significantly higher in the subgroup with estimated cumulative exposure >68 mg/m(3).y. In all miners, plasma GSH-Px activity was correlated with Se concentration (r=0.22, p<0.005). The 4 year Se changes were negatively related to exposure to high dust concentrations and positively related to change in exposure from high to retirement and to change from smoker to ex-smoker (p=0.01). CONCLUSION: The variations of Se concentration in relation to changes in occupational exposure to coal dust and in smoking habits, and the close correlation found between plasma Se concentration and GSH-Px activity suggest that both are required in antioxidant defence. These results agree well with the hypothesis that the decrease in Se concentration reflects its use against reactive oxygen species generated by exposure to coal mine dust and by smoking. (+info)

A 78-year-old retired pig farmer developed brucellosis and died of liver failure >20 years after her last exposure to infected livestock. This is an exceptionally long incubation period for this infection, which usually presents within weeks of exposure. (+info)
Relationship of suicide rates to social factors and availability of lethal methods: comparison of suicide in Newcastle upon Tyne 1961-1965 and 1985-1994.
(20/444)
BACKGROUND: The UK Government's White Paper Saving Lives: Our Healthier Nation included among its targets a reduction in suicide. AIMS: To study causes of change in suicide rate over a 30-year period in Newcastle upon Tyne. METHOD: Suicide rates and methods, based on coroners' inquest records, were compared over two periods (1961-1965 and 1985-1994) and differences were related to changes in exposure to poisions and prescribed drugs, and to socio-demographic changes. RESULTS: Demographic and social changes had taken place which would adversely affect suicide rates. However, a dramatic fall was found in the rate for women, and a modest decline in that for men. Reduced exposure to carbon monoxide and to barbiturates coincided with the fall in rates. CONCLUSIONS: Reduced exposure to lethal methods was responsible for the fall in rate in both genders, while the gender difference in favour of women may be related to their preference for non-violent methods or to their being less affected by the social changes.

Promotion of work ability, the quality of work and retirement.
(21/444)
In this study, the validity of a model designed to promote the work ability of aging workers was examined. The target areas of work ability promotion were searched for the characteristics that explain work ability the best. In addition, the way work ability relates to the quality of work and retirement was examined. The subjects (n = 1101) participated in the follow-up study on aging Finnish workers in 1992 and 1997. The results consistently supported the model for promoting work ability. All four areas of focus-(i) work demands and the environment; (ii) work organization and the work community; (iii) the promotion of workers' health and functional capacity; and (iv) the promotion of professional competence-proved to be strongly associated with work ability. Good work ability was associated with a high quality of work and the enjoyment of staying in one's job. It also predicted active and meaningful retirement. (+info)
Demonstration of the healthy worker survivor effect in a cohort of workers in the construction industry.
(22/444)
OBJECTIVES: To assess the potential of a healthy worker survivor effect due to differential occupational mobility in a cohort of construction workers. METHODS: A cohort of 10 809 male employees in the German construction industry aged 15-64 years was followed up for occupational mobility, early retirement due to permanent disability, and total mortality from 1986 to 1994. Using the Cox's proportional hazards model of relative rates (RRs) with 95% confidence intervals (95% CIs) of occupational mobility, early retirement and total mortality were estimated according to medical diagnoses at baseline after adjustment for various covariates. RESULTS: During follow up, 2472 subjects changed employment, 359 employees were granted a disability pension for health reasons and 188 subjects died. A wide range of chronic diseases was associated with increased rates of early retirement and total mortality but not occupational mobility. However, a healthy worker survivor effect was identified related to disorders of the back and spine (ninth revision of the international classification of diseases, ICD-9, code 720-4), a common predictor of both occupational mobility (RR 1.17, 95% CI 1.04 to 1.32) and early retirement (RR 1.50, 95% CI 1.20 to 1.88). In total, there were about as many events of occupational changes (n = 41) as events of early retirement due to permanent disability (n = 39) significantly attributable to disorders of the back and spine. Differential occupational mobility preceded differential early retirement due to permanent disability by more than one decade. CONCLUSIONS: These findings show the need to consider a healthy worker survivor effect due to occupational mobility in occupational epidemiological research. Furthermore these results underline the necessity of further health promotion targeting work related conditions in the construction industry. (+info)
Propensity for osteoarthritis and lower limb joint pain in retired professional soccer players.
(23/444)
OBJECTIVE: To quantify the prevalence of osteoarthritis and the severity of pain in the lower limb joints of players retired from English professional soccer. METHOD: An anonymous self administered questionnaire was distributed to 500 former players registered with the English Professional Footballers' Association. The questionnaire was designed to gather information on personal details, physical activity loading patterns, history of lower limb joint injury, and current medical condition of the lower limb joints. RESULTS: Of 500 questionnaires distributed, 185 (37%) were returned. Nearly half of the respondents (79: 47%) retired because of injury; 42% (33) were acute injuries and 58% (46) chronic injuries. Most of the acute injuries that led to early retirement were of the knee (15: 46%), followed by the ankle (7: 21%) and lower back (5: 15%). Most of the chronic injuries that led to early retirement were also of the knee (17: 37%), followed by the lower back (10: 22%) and the hip (4: 9%). Of all respondents, 32% (59) had been medically diagnosed with osteoarthritis in at least one of the lower limb joints. More respondents had been diagnosed with osteoarthritis in the knee joints than either the ankle or the hip joints. Significantly (p<0.001) more respondents reported pain in one lower extremity joint during one or more daily activities than those who did not (joint pain: 137, 80%; no joint pain: 35, 20%). CONCLUSION: The risk for professional soccer players of osteoarthritis in at least one of the lower extremity joints is very high and significantly greater than for the general population. The results support the suggestion that professional soccer players should be provided with health surveillance during their playing career. (+info)
Dental school vacant budgeted faculty positions: academic year 2000 - 2001.
(24/444)
The 1999 Report of the AADS President's Task Force on the Future of Dental School Faculty (1) drew attention to the situation dental schools are experiencing in attracting and retaining faculty. A year 2000 ADEA Association Report on faculty shortages indicated the number of vacant budgeted positions was approaching 400 (2). The year 2000 - 2001 ADEA survey of vacant budgeted positions indicates a further four percent increase in vacant budgeted positions. Over 73 percent of the vacancies were in the clinical sciences. Of identified full time faculty separations in the 2000-2001 ADEA Survey of Dental Educators (3), almost 34 percent were due to retirements; 33 percent were faculty moves to other schools; and a little over 18 percent were moves to enter private practice. Almost three percent of identified faculty separations were from deaths. It is anticipated that, with a further "graying" of an already aged dental school faculty, retirements will further exacerbate the problem of faculty vacancies and the ability to attract and retain new faculty. There is needed urgency in implementing strategies and recommendations provided in the 1999 President's Report and the 2000 Association Report. (+info)
