    Abstract:
    CONTEXT: Reports on psychiatric morbidity in males with congenital adrenal hyperplasia (CAH) are lacking. OBJECTIVE: The aim was to study psychiatric disorders in CAH males. DESIGN, SETTING, AND PARTICIPANTS: We studied males with CAH (21-hydroxylase deficiency, n = 253; CYP21A2 mutations known, n = 185), and compared them with controls (n = 25 300). Data were derived through linkage of national population-based registers. We assessed the subgroups of CYP21A2 genotype separately (null, I2splice, I172N, P30L, and NC), as well as outcomes before and after the introduction of national neonatal screening in 1986. MAIN OUTCOME MEASURES: Psychiatric disorders including attempted and completed suicide (suicidality) were reviewed. RESULTS: Psychiatric disorders (suicidality not included), suicidality, and alcohol misuse were increased in CAH males compared with controls (odds ratios, 1.5, 2.3, and 1.9; 95% confidence intervals, 1.1-2.2, 1.1-5.0, and 1.0-3.5, respectively). In the null genotype group, no increased rates were seen; in the I2splice group, psychiatric disorders, personality disorders, and alcohol misuse were increased; in the I172N group, suicide attempt and drug misuse were increased; and in the P30L and NC groups, psychotic disorders were increased. In CAH males born before the neonatal screening, the rates of psychiatric disorders and suicidality were increased, but only psychotic disorders increased in those born afterward. There was no increased risk for any neurodevelopmental disorder. CONCLUSIONS: CAH males have an increased psychiatric morbidity. Psychiatric morbidity was not raised in the most severe genotype group. Late diagnosis of CAH may explain some of the findings. Those born before the introduction of neonatal screening were more affected, which may be explained by the higher age.
