“…The concept of strain in this study is based on the stress-strain model where the stress on a worker depends on environmental factors (both physical and psychosocial) acting upon the person, whereas strain denotes the effects of stress which differ by individual for a certain stress factor (Rutenfrantz, 1981;Cox et al, 2000). The stress and strain concept has been widely used in studies on the effects of physical work load on both the cardiovascular as well as the musculoskeletal system (Rutenfranz, 1981, Nygård et al, 1988. The model emphasizes the role of individual characteristics such as age, gender, health status and work ability as modifiers of the relationship between strain and musculoskeletal symptoms or pain.…”

This study evaluates whether physical and mental strain are associated with an onset and persistence of multi-site pain among younger and older employees in a four year of followup. A questionnaire survey was conducted in a food processing company twice, in 2005 and 2009 with the response from 734 employees in the age between 20 and 66 years (445 younger and 289 older; 65% female). Information on musculoskeletal pain during the preceding week and perceived mental and physical strain was obtained through a structured questionnaire. The association of onset and persistence of multi-site pain with mental and physical strain was estimated with log binomial regression analysis and stratified by agegroup. Risk ratio (RR) with their 95% confidence intervals (CIs) are reported for the estimates. More than 56% of the employees reported multi-site pain at baseline. Among those who reported multi-site pain at baseline 70% reported persistence of multi-site pain and one third had new onset of multi-site pain at the follow-up. Mental strain at baseline strongly predicted persistence of multi-site pain among both younger and older employees (RR from for younger employees = 1.68, 95% CI = 1.01-2.83 and RR for older employees = 2.25, 95% CI 0 1.27-3.98). The high mental strain predicted the risk of persistence multisite pain among both younger and older employees in a four year follow-up but not onset of multi-site pain.

“…Similarly, compared to other jobs of job types in European studies (Aunola et al 1979;Ilmarinen 1984;NygaÊ rd et al 1988;Ahonen et al 1990;SuurnaÈ kki et al 1991), the average HR or %HRR in ST (91.8 beats á min A1 , 22.4%) was higher than that of medical secretaries, crane drivers, administrators, keypunchers and typists, machine workers, instrument-®tters, clerks, occupations categorized as``mental work,'' and the work with low musculoskeletal load, but lower than that of dairy farmers, cleaners, auxiliary, home-care workers, surface ®nishers, occupations categorized as``physical work,'' and work with high musculoskeletal loads. It was similar to that of sales women, nursing, and occupations categorized as``mixed physical and mental work.''…”

Comparisons were made of general and local physical work loads between two groups of 58 Japanese and 15 Swedish nursery school teachers. Heart rate, number of steps, rating of perceived exertion (RPE), frequency and time expended with respect to trunk flexion, sitting/kneeling, and lifting/carrying loads of 1 kg or more were monitored during working hours. The average percentage heart rate increase in the maximal heart rate range was lower in the Japanese than in the Swedish teachers. However, all parameters of local physical work load indicating musculoskeletal stress were higher in the Japanese than in the Swedish teachers. The RPE was slightly higher in the Japanese than in the Swedish teachers. These features of general and local work load in the Japanese teachers were typically observed among the teachers in charge of very young children (0-2 years). The Japanese teachers in charge of children aged 3-5 years, on the other hand, had similar levels of both general and local work load as the Swedish teachers in charge of classes comprising children of various ages (1-5 years). The physical work load measured in the present study was not sufficient to explain the difference in the magnitude of musculoskeletal problems for nursery school teachers in the two countries, and other factors should now be examined.
