Introduction: Coronary artery diseases (CADs) are one of the main causes of mortality and morbidity in Iran. Due to the shortage of information regarding sleep status in the area and also the close relation between CADs and sleep health, this study attempted to examine sleep status in a large urban area of southeast Iran in order to find its relation with CADs risk factors such as anxiety and depression, hypertension, blood glucose level, smoking, low physical activity, and obesity.

Method: A Single-stage cluster sampling cross-sectional study was carried out on 5900 people aged 15 to75 in Kerman city to examine the CAD risk factors (KERCADR study). Alongside, sleep screening and a physical activity (PA) questionnaire regarding their sleep quantity and PA level were also used. Beck Anxiety and Beck Depression Inventories (for anxiety and depression assessment), medical examination and fasting blood sample were taken to collect the participants' demographic and blood glucose data.

Findings: From 3238 (54.9%) women and 2662 (45.1%) men who participated in this study 30.5%suffered from abnormal sleep (11.5% from insomnia and 19% from hypersomnia). 39.3% of the men and 45.1% of the women had low physical activity. There was a significant relationship between smoking (p=0.02), anxiety and depression (p<0.001), hypertension (p=0.03) and low PA (p=0.01) with sleep disorders.

Conclusion: the results showed that nearly one-third of the adult population suffered from abnormal sleep. Also, the prevalence of hypersomnia was 1.65 times more than that of insomnia. This issue along with the high prevalence of low physical activity exposed the population to different diseases.
