[Effects of shift work on quality of sleep among retired workers].
To examine the relationship between shiftwork experience and quality of sleep after retirement, we carried out a self-reported questionnaire survey on 777 retired workers of a manufacturing company. Questionnaire items included past illness, current health status, dietary habit, alcohol drinking, smoking, regular exercise, sleep, working condition (job, shift work experience, shift work periods and side job), current working status, social activity, educational background, sex, age and number of years since retirement. Present health status (adjusted odds ratio 4.318, 95% CI 2.475-7.534), shift work experience (2.190, 1.211-3.953), present working status (1.913, 1.155-3.167) and dietary habit (1.653, 1.055-2.591) were significantly related to sleep disturbance after retirement by multiple logistic regression analysis. To prevent sleep disturbance after retirement, people should keep a regular lifestyle and good health status, especially ex-shift workers.
