Predict the risk of cardiovascular and gastrointestinal disease through sleep quality and chronic fatigue in shiftworkers

Current research have shown that among psychological factors، sleep quality and chronic fatigue plays a role in the prevention and treatment of cardiovascular and gastrointestinal diseases. The purpose of this study was to predict the risk of cardiovascular and gastrointestinal disease through sleep quality and chronic fatigue in shiftworkers. 195 shift workers of an industrial company were selected by stratified random sampling and they completed survey questionnaires. The scales used for this study were 18-item physical diseases questionnaire (with two subscales)، 11-item sleep quality questionnaire and 10-item chronic fatigue questionnaire. The results showed that there is significant correlation between shift workers sleep quality and risk of physical disease and its subscales (p<0. 0001). There is significant linear correlation between shift workers’ chronic fatigue and risk of physical disease and its subscales (p<0. 0001). Multiple linear regression analysis showed that there are relationships between shiftworkers sleep quality and chronic fatigue with risk of physical disease (R2=0. 266، p<0. 0001). Overall،، based on these findings، we can say that poor sleep quality and chronic fatigue of shiftworkers increases risk of cardiovascular and gastrointestinal diseases.
