In addition to the reasons for eating and exercise, display obesity and sleep-related factors in the relationship is worth it to explore further.
Purpose：Our study was designed to evaluate the factors that affect of sleep quality in Taiwan, content of the factor included body mass index, Chronic Diseases, night eating behavior et al.
Methods：This study applied a cross-sectional design, and conducted using structured questionnaires, content of the questionnaire included Pittsburgh Sleep Quality Index（PSQI）, Night Eating Questionnaire（NEQ）, Exercise Habits, and demographics. Data were collected from August 2014 to December 2014. Access method used by Computer Assisted Telephone Interview System（CATI）. The subject is the people lived in Taiwan and the age ranged from 18 to 69, there are 17,269,426 sample（consisted of 8,608,299 male and 8,661,127 female）（data got from interior ministry of ROC, 2014） as the studying population. The successfully sample of 1,067 participated in our protocol, and the successful sampling rate is 6.17‰‰. All data were processed by Chinese version of SPSS statistical software for windows 21.0 system to descriptive and inferential statistical analysis.
Results：The results show average total sleep quality score 4.89 points (SD = 2.614), of which 29.2% of conscious poor sleep quality. Further analysis revealed the chronic diseases could mediate the effects of the body mass index and sleep quality, for the sleep quality has a negative impact.
