Women suffer from sleep disorders more than men mainly due to lifestyle and hormonal factors. A study in which 1,440 women from different ethnic backgrounds were questioned about their sleep revealed that African-American women were more likely than Caucasian women to have short sleep (12% vs 8%) and longer sleep (11% vs 9%),which may put them at higher risk of medical problems associated with extreme sleep durations. It was also seen that Eastern European women were more likely to have symptoms of insomnia than European American women (77% vs 0%), where as Haitian and Caribbean women were least likely to have insomnia (34% and 33%). The results suggest that the difference in sleep patterns among women may be determined by ethnicity.
