Low back pain, work absenteeism, chronic back disorders, and clinical findings in the low back as predictors of hospitalization due to low back disorders: a 28-year follow-up of industrial employees.
Study Design. Prospective cohort study. Objective. To study symptoms, chronic disorders, and clinical findings in the low back, and work absenteeism, as predictors of hospitalization. Summary of Background Data. Socioeconomic and lifestyle factors are associated with back-related hospitalization, but the significance in the working normal population of low back symptoms and clinical findings are not known. Methods. The cohort (n = 902) was drawn in 1973 from among employees in the metal industry (n = 2,653). The data were collected by questionnaire and a structured clinical assessment by a physiotherapist. Weight was measured. A sum score of local and radiating low back symptoms (frequency …
Persistence of low back pain reporting among a cohort of employees in a metal corporation: A study with 5-, 10-, and 28-year follow-ups
Low back pain (LBP) is a common symptom among adults but little is known about its persistence over time in defined populations. The aim of this study was to examine the persistence of LBP among a cohort of industrial employees studied in four successive surveys during a total of 28 years. Cross-tabulations and logistic regression was used to estimate the interdependence of LBP occurrence at the surveys. At baseline, 54% of the subjects reported local LBP and 25% LBP radiating to the lower limb(s). Persistent or recurrent LBP was common. Of those with LBP at baseline, 75, 73, and 88% reported it also at the 5-, 10- or 28-year follow-up, respectively. Of those with radiating pain, 66, 65, an…
Työn, aikuiskoulutuksen ja tutkimuksen yhteydet
Professori Juhani Kirjonen haastatteli Yhdysvaltoihin ja Kanadaan suuntautuneella matkallaan kahdeksaa aikuiskasvatuksen tutkijaa ja tiedemiestä. Haastattelujen II osa julkaistaan oheisena. Matka toteutui Suomen Akatemian apurahan turvin ja liittyi osaamista valtionhallinnossa käsittelevään tutkimushankkeeseen. Hankkeen tavoitteena on kehittää tieteidenvälistä ammatillista jatkokoulutusohjelmaa ja tutkia, miten työtä ja ammattitaitoa voidaan kehittää tutkijoiden ja ammattilaisten keskinäisen koulutusyhteistyön avulla. Tässä numerossa ovat professorien David Kolb, Lynn Davie ja Mihaly Csikszentmihalyin sekä tohtori Elizabeth Burgen haastattelut. Lisäksi haastattelija selostaa lyhyesti profes…
Stability and prediction of physical activity in 5-, 10-, and 28-year follow-up studies among industrial employees.
The aim of the study was to examine the stability of voluntary and household physical activity (PA) and to compare it with that of the use of the most common stimulants. The prospective cohort study comprised of follow-ups at 5, 10, and 28 years at baseline in 1973 in four plants of an industrial corporation in Finland. A systematic, non-proportional sample (n=902, age range 18-64 years) stratified for age, gender, and occupational status was drawn from the employees. Scores of PA were based on a questionnaire and interviews. Logistic regression models with proportional odds assumptions were counted. The 5-year stability (Spearman's rho) of PA time was 0.44 (PA intensity 0.44), the respecti…
The Acquisition of Professional Expertise—a challenge for educational research
This article examines the acquisition of professional expertise from the educational viewpoint and outlines emerging approaches to research on expertise. The starting points are the need to reflect the nature and content of expertise in the changing world and the aim to understand the preconditions for integrating the viewpoints of working life and education in developing prerequisities for expertise in educational contexts. The section after the Introduction briefly reviews how expertise has been conceptualized in recent research. The next section deals with the role of higher education in developing expertise from the viewpoint of constructivist approaches in research on learning. Then cu…
