Recent life stresses such as a loss of a family member or friend, loss of a job, or social isolation (such as living alone) increase the risk.  Those who have never married are also at greater risk.  Being religious may reduce one's risk of suicide.  This has been attributed to the negative stance many religions take against suicide and to the greater connectedness religion may give.  Muslims , among religious people, appear to have a lower rate of suicide; however the data supporting this is not strong.  There does not appear to be a difference in rates of attempted suicide rates.  Young women in the Middle East may have higher rates. 
Individuals with OCD have also been found to be affected by delayed sleep phase syndrome at a substantially higher rate than the general public.  Moreover, severe OCD symptoms are consistently associated with greater sleep disturbance. Reduced total sleep time and sleep efficiency have been observed in people with OCD, with delayed sleep onset and offset and an increased prevalence of delayed sleep phase disorder.
