[Analysis of clinical characteristics and disease spectrum trend of children in short stature outpatient clinic of a tertiary hospital in Beijing in different years].

Objective: To analyze the clinical characteristics and disease spectrum trend of children in short stature outpatient clinic of Beijing Children's Hospital, Capital Medical University in different years. Methods: A retrospective analysis was performed on the medical records of children attending the short stature outpatient department of Beijing Children's Hospital, Capital Medical University during the summer vacation (July 1 to September 30) in 2021, 2023 and 2025. Analyze the clinical characteristics and their distribution of children patients in 3 years. The Mantel-Haenszel trend χ² test was used to analyze the changing trends of various indicators and disease spectrum across the 3 years. Results: A total of 5 862 children were enrolled, including 3 022 boys and 2 840 girls, with the age of (9.6±3.2) years and the height of (131.7±20.4) cm. The age of children in the three years was (9.0±3.3), (9.6±3.1), and (10.1±2.9) years, respectively. No infants were admitted to the short stature outpatient clinic in any of the 3 years. The proportion of children in the toddler and preschool periods decreased year by year, while that in the school-age and adolescent periods increased gradually (all Ptrend<0.001). The height of children in the 3 years was (123.4±23.9), (131.6±19.9), and (139.9±21.2) cm, respectively. The proportion of children with low height percentile (<P3, P3-<P10) showed a decreasing trend, whereas the proportions of children with moderate to high height percentile (P25-<P50 to≥P97) presented an increasing trend (all Ptrend<0.05). The proportion of children with constitutional short stature decreased year by year, while the proportions of patients with adolescent short stature, slow or poor height growth, and precocious puberty increased annually (all Ptrend<0.05). Conclusion: During the summer periods of 2021, 2023 and 2025, among patients visiting the short stature outpatient clinic of Beijing Children's Hospital, Capital Medical University, the proportions of school-age and adolescent children, children with height at≥P25 percentile, and cases of precocious puberty all increased year by year.
