P rospective studies with a follow-up time stretching from midlife to old age have shown that lower socioeconomic status, as indicated by lower education level or occupational grade, predicts a decline in health and functioning in the working population.1-4 This association is similar, if not more pronounced, in old age. 5-7Higher levels of work-related mental and physical strain increase the risk of early retirement and predict a decline in health and an increase in mortality among the working population. 3,[8][9][10][11][12][13][14][15] However, the association between the demands of the work in conjunction with inadequate mental or physical resources (i.e., work ability) 16 and health and functioning in old age has not been studied.17 Using a population-based 28-year follow-up study involving middle-aged municipal employees, we investigated whether work ability in midlife predicts the risk of death and disability during old age among white-collar and blue-collar employees. Methods Participants and designThe Finnish Institute of Occupational Health's Finnish Longitudinal Study on Municipal Employees (FLAME) targeted 7344 individuals aged 44-58 years at baseline in 1981.18 The participants had been chosen at random from members of all municipal professions in Finland. The baseline cohort consisted of 6257 employees (44.7% men), for a response rate of 85.2%. The first questionnaire, which explored work, health and lifestyle factors, was sent out in 1981, and follow-up data were collected in 1985, 1992, 1997 and 2009. Data on work ability were missing for 199 women and 87 men. The analyses in this study are based on the responses of 5971 Work ability in midlife as a predictor of mortality and disability in later life: a 28-year prospective follow-up study Mikaela B. von Research CMAJ Background: Poor work ability correlates with increased morbidity and early retirement from the workforce, but the association in old age is not known. We investigated work ability in midlife among white-collar and blue-collar employees as a predictor of mortality and disability 28 years later.

The rapid aging of the workforce in most developed countries, and the strengthening presence of bridge employment among older employees, has brought about a need for a deeper theoretical and practical understanding of this employment phenomenon. This study examined the concept of bridge employment from a continuity theory and life course perspective. Several personal and job-related antecedents of 539 middle-aged and older U.S. Federal Government employees' intentions of full retirement or engagement in bridge employment were investigated. A multinomial logistic regression analysis provided support for most of the hypotheses on the antecedents of full retirement and overall bridge employment intentions and hence offered several practical implications for the U.S. Federal Government, as well as other governmental employers. Implications of these results are discussed from a continuity theory and life course perspective.

Adverse work- or health-related factors detected in middle age predicted subsequent early retirement intentions.
