Treatment outcomes of gonadotropin-releasing hormone agonist in obese girls with central precocious puberty

Purpose This study investigated the influence of obesity on the clinical course and effect of gonadotropin-releasing hormone analog (GnRHa) treatment in girls with central precocious puberty (CPP). Methods Medical records of 182 girls with CPP treated with GnRHa were reviewed. They were divided into 2 groups: normal weight (n=108) and overweight/obesity (n=74). Chronological age (CA), bone age (BA), difference between BA and CA (BA–CA), standard deviation score (SDS) of height, body mass index (BMI), predicted adult height (PAH), and laboratory findings were compared at baseline, after 1 year, and at the end of GnRHa treatment in both groups. Results Mean BMI SDS at baseline was 0.08±0.60 in the normal weight group and 1.55±0.36 in the overweight/obesity group. Initial CA, BA, midparental height, and PAH were similar between the 2 groups. BA–CA after treatment was significantly decreased compared to baseline in both groups (P<0.001). Between the 2 groups, a decrease in BA–CA during treatment showed no significant difference. PAH at the end of treatment was significantly increased compared to baseline in both groups (P
