title: The first 900: a nine-year longitudinal analysis of consecutive adolescent inpatients.
abstract: Data for the presenting complaints, average age and sex distribution, average length of stay and the discharge diagnosis for 900 consecutive adolescents treated at the Adolescent Center of Houston International Hospital between 1974 and 1982 were reviewed. The number of cases remained fairly constant over the 9 years. As the males and females showed an increase in age, the increase in age for males (13.4 years to 15.2 years) was greater than that for females (14.4 years to 15.0 years). The average age for male admissions during 1974-1976 was significantly lower than 1980-1982 (p less than 0.03). The average length of stay for males during 1980-1982 was significantly greater than 1974-1976 (p less than 0.05). The most frequent presenting symptoms in decreasing order for 1974-1982 were depression, school problems, family problems, threatening behavior, runaway behavior, and suicidal ideation. Depression increased from 15.6% in 1974-1976 to 29.6% of presenting symptoms. Substance abuse increased from 4% (1974-1976) to 8.8% (1980-1982). Suicidal ideation increased three-fold over the same period (3.3% to 10.6%). A significantly greater number of males presented with 1) impulsivity, 2) aggressiveness, 3) withdrawal behavior, 4) stealing, and 5) disruptive behavior. A significantly greater number of females presented with 1) runaway behavior, and 2) suicidal ideation. The 10 most frequent discharge diagnoses are listed. Depression as a diagnosis increased almost four-fold between 1977-1979 and 1980-1982 (7.6% versus 27.5%).
