Psychiatric diagnostic profiles in hospitalized adolescent and adult Navajo Indians.

Diagnostic profiles of 400 adolescent and 1159 adult Navajo Indians consecutively admitted to a psychiatric unit between 1980 and 1989 are presented in this paper. The major discharge diagnoses for adolescents were as follows: adjustment reaction, mixed, and depression, not otherwise specified (NOS), with females accounting for two-thirds of either diagnosis; schizophrenia, with males accounting for 68% of all diagnoses, and personality disorder, NOS, with no gender differences. The four major discharge diagnoses for adults were schizophrenia and depression, NOS, in which there were no gender differences; alcohol withdrawal, syndrome, in which males accounted for 76% of those discharged; and adjustment reaction, mixed, in which females constituted 60% of those discharged. Over the 10-year period, there was a decrease in adult and an increase in adolescent admissions. During the last 2 years (1988 and 1989) adolescents accounted for almost 30% of all admissions compared with 14% during the first 2 years (1981 and 1982).
