Physical job strain has been linked to musculoskeletal disorders, increased need for institutional care and premature death. The aim of the study was to investigate how physical job strain in midlife is related to the development of physical functioning later in life in men and whether occupational status and physical activity influenced the development of physical job strain and physical functioning in middle-aged work.\n\nThe data of this study belong to the Helsinki Birth Cohort Study (HBCS) from 2001\u20132018. The study involved 928 men, with a mean age of 61.5 years in 2001. Three trajectories of the development of physical functioning were formed based on the results of the physical functioning of the SF-36 survey. The physical job strain factors in midlife were based on the occupational titles of the subjects according to the 1990 occupational classification data of the Population Register and were validated using the gender-specific occupational exposure matrix (JEM) of the Finnish Institute of Occupational Health. The physical job strain factors studied were physically strenuous work, kneeling, driving, heavy lifting, working hands above shoulders, awkward posture, lifting, hand force, repetitive hand movements, sitting and standing. From these, two factors were formed using factor analysis, from which the sum variables difficult work position and movements and the use of physical force and driving were calculated. The association between the sum variables and the physical functioning at later life in men was examined by multinomial regression analysis.\n\nBoth sum variables, awkward working position and movements, and physical force and driving reduced the probability of being on the trajectory of the best physical performance compared to the trajectory of the weakest physical performance (OR 0.997, 95% CI 0.996\u20130.999 p = 0.002), (OR = 0.996, 95% CI 0.992\u20131,000 p = 0.030). When the model was adjusted by a social class the connection did not remain statistically significant and further deteriorated when physical activity was added to the model. The impact of the social class on the development of the physical job train in midlife and the physical functioning later life in men was significant.\n\nThe association between the physical job strain in midlife and the weaker development of physical functioning later in life was not preserved when the model was standardized by the social class. Attention should be paid to the physical job strain of middle-aged men, especially in blue collars, in order to ensure functional life years, and to identify harmful thresholds for physical job strain in terms of physical functioning.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2022-06-28T07:23:57Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-06-28T07:23:57Z (GMT).
