Qigong training and effects on stress, neck-shoulder pain and life quality in a computerised office environment.

BACKGROUND: Qigong is a Chinese health promoting exercise with a rhythmic pattern of slow movements and breathing affecting the autonomous nervous system. OBJECTIVES: To examine the implementation of Qigong for half an hour daily in a computerised office, and to study effects on health state, general health, neck-shoulder and lumbar spine symptoms and stress after six weeks training DESIGN: A crossover intervention study with 37 employees randomised in two groups. A questionnaire was completed one week before starting study and every second week during the training period. After 6 weeks the first group stopped and the second group started the training. RESULTS: There was a small significant improvement of neck pain and disability following therapy. CONCLUSION: Qigong training may reduce neck disability in office workers. A longer training period might be needed in further Qigong studies in healthy, normal populations.

Personal and psychosocial factors and symptoms compatible with sick building syndrome in the Swedish workforce.

A random sample of 1000 subjects (20-65 years of age) received a postal questionnaire regarding sick building syndrome (SBS), including the three-dimensional model of demand-control-support (DCS). The response rate was 70% (n = 695), and 532 were occupationally active. Female gender and atopy were the main predictors of symptoms. Eye symptoms were more common at low social support combined with strained work situation [odds ratio (OR) 2.37], and at high social support combined with active work situation (OR 3.00). Throat symptoms were more common at low social support combined with either passive (OR 1.86) or strained situation (OR 2.42). Tiredness was more common at low social support combined with either passive (OR 2.41), strained (OR 2.25), or active situation (OR 1.87), and at high social support combined with active work situation (OR 1.83). Low social support combined with either passive (P = 0.01) or strained job situation (P = 0.01) was associated with a higher symptom score (SC). The lowest SC was found at a relaxed work situation, irrespective of social support. In conclusion, female gender, low age, asthma, atopy and psychosocial work environment are associated with symptoms. The three-dimensional model can predict symptoms compatible with SBS, but in a more complex way than earlier research indicated. Practical Implications A multi-disciplinary approach, including psychosocial stress factors as well as personal factors such as gender, age, atopy and asthma, and indoor exposures, should be applied in studies on symptoms compatible with sick building syndrome (SBS). Males and females perceive psychosocial work conditions differently, and may react differently to job stressors. The psychosocial work environment can be as important as gender and atopy as a predictor of SBS symptoms.

The effects of a change in work organization upon the work environment and musculoskeletal symptoms among letter carriers.

An organizational change among 82 postal workers was studied with the aim of evaluating the effects on the work environment, work ability, and musculoskeletal complaints. The study was undertaken in 2 suburbs of Stockholm, Sweden. Psychological work demands were estimated to be reduced at the 1-year follow-up but physical work demands had changed very little. In an observation study in a subgroup of older workers, the risk of overexertion at work and musculoskeletal complaints was reduced. In spite of that, most of the older participants (>/=35 years) had unchanged or increased musculoskeletal symptoms. This shows the need for early preventive measures.
