Growth and development status of children with severe β-thalassemia and its correlation with serum HGB and SF levels in Bazhong area / 公共卫生与预防医学

ABSTRACT

Objective To analyze the growth and development status of children with severe β-thalassemia major (β-TM) in Bazhong area and its correlation with hemoglobin concentration (HGB) and serum ferritin (SF) level, and to provide a theoretical basis for the diagnosis and treatment of children with β-TM in Bazhong area. Methods A total of 292 children with β-TM admitted to Bazhong Central Hospital from January 2019 to December 2020 were selected. The Z-score method was used to evaluate the growth and development of the children. According to the growth and development of the children, they were divided into the normal group (normal growth and development, n=163) and delayed group (growth and development delay, n=129). Another 60 healthy children were selected as the control group. The levels of HGB, serum SF, free triiodothyronine (FT3), free tetraiodothyroxine (FT4), and thyroid stimulating hormone (TSH) were compared among the three groups of children, and clinical data such as age, sex and age of onset were collected from the case system. Univariate analysis and logistic regression were used to analyze the independent risk factors of growth and development delay in β-TM children. Pearson correlation was used to analyze the correlation between growth retardation and HGB and serum SF levels in β-TM children. Results The serum SF and TSH levels in the delayed group were significantly higher than those in the normal group and the control group, while the levels of HGB and serum FT4 were significantly lower than those in the normal group and control group (P2000 ng/mL were risk factors for growth retardation in β-TM children (P2000 ng/mL, the height, weight, and HGB and serum SF levels should be monitored regularly.
