Females represented 59.9 percent of the 34.7 million short-stay hospital discharges in 2005. More than 19 percent of hospital stays for all females were due to childbirth, while 14.6 percent were due to diseases of the circulatory system. Other common reasons for hospitalization included diseases of the respiratory, digestive, and genitourinary systems; injury and poisoning; and mental disorders.
