||Comparison of reported workplace morbidity in 8-hour and 12-hour shifts in one plant
||Autumn 1989, Vol.39, No.3, p.81-84. 15 ref.
||A retrospective study of the minor morbidity diagnoses of 775 workers during two 10-year periods was undertaken. During the first, they worked an 8-hour rotating shift, during the second, a 12-hour shift system. Stress related symptoms were identified from medical reports kept by the plant health service. By age-sex standardisation and the calculation of morbidity ratios and confidence intervals, it was shown that the introduction of the 12-hour shift system was accompanied by a statistically significant fall in the incidence of stress-related complaints such as headaches, gastrointestinal upsets and alcohol-related complaints. No reduction was found in the incidence of other illness complaints, considered to be unrelated to stress.
