To date, the question of the effect of the nature of the course of bronchial asthma on the state of bone tissue in patients is being studied. 465 children with bronchial asthma aged 7 to 16 years were monitored. The examined performed ultrasound osteodensitometry. We found that 72.3% of patients with bronchial asthma had a low body mass index, and in 22.1% of the examined body mass index exceeded the average values. Only in 5.6% of patients its value was within the normal range. The average level of physical development was revealed in 64.3% of patients, above the average - in 16.5%, below the average - in 12.9%, and high and low physical development in 4.1% and 2.2% of patients, respectively. According to ultrasonic osteodensitometry in the presence of asthma in patients, a significant decrease in the mean values of the bone density index, broadband ultrasound attenuation and ultrasound propagation velocity relative to the comparison group values was registered. In patients receiving long-term inhaled glucocorticosteroids, all densitometry indicators were lower than in patients who did not take them or who were on short courses of this therapy. When analyzing the gender characteristics of ultrasound osteodensitometry, we identified the fact of a greater risk of developing bone fractures in female patients.
