Ninety-eight percent of patients had a chronic condition: 37.1% where overweight or obese, 58.2% had a congenital heart disease, 11.9% where being evaluated or had the diagnosis of autism and 44.8% had hypothyroidism. Pubertal development was consistent with chronologic age in 93.7% of patients. In three patients puberty had been suppressed. In women, average age of menarche was 12.2 ± 1.1 years.
