A Clinical Study of Girls With Idiopathic Central Precocious Puberty and Psychological Behavior Problems

To understand the psychological effects on behavior of girls with idiopathic central precocious puberty (ICPP) and to explore the role of gonadotropin-releasing hormone analog (GnRHa) in the reversal or blocking of the negative psychological effects on behaviors of girls with ICPP. A total of 100 girls with ICPP diagnosed at the Department of Endocrinology of Jiangxi Children's Hospital were divided into the treatment group and observation group with 50 cases in each group. The control group consisted of 50 healthy girls examined at our hospital during the same period. The Achenbach Child Behavior Check List ([CBCL] for parents) was used to evaluate the psychological effects on behavior of the girls diagnosed with ICPP and the girls in the control group, and the scores of related behavioral factors were calculated. At the same time, the psychological effects on behaviors of the girls with ICPP treated with GnRHa were followed up. (1) There were 100 girls with ICPP and 30 with behavioral problems. There were 50 normal healthy girls (control group) with 3 cases of behavior problems. Of the 50 girls with ICPP, after treatment, 8 had behavioral issues. The rate of abnormal psychological effects on behavior in the group of girls with ICPP before treatment was significantly higher than in the control group (P < .01), and after treatment, the rate was lower than before treatment (P < .05). (2) The scores of depression, social withdrawal, poor communication, and school discipline violation in the ICPP group were higher than those in the control group, with a statistical significance (P < .01). (3) After 24 months of GnRHa treatment for girls in the ICPP group, the scores of 4 factors, including depression, social withdrawal, poor communication, and violation of discipline in the Achenbach CBCL, were significantly different before and after treatment (P < .05). (1) Girls with ICPP have low self-esteem, low self-confidence, high incidences of psychological effects on behavior problems, manifested in depression, withdrawal, poor communication, discipline violations, and other aspects; (2) GnRHa treatment can reverse the low self-esteem and low self-confidence of girls with ICPP to varying degrees.
