摘要
目的:了解北京市石景山区0~3岁婴幼儿骨密度情况。方法:选取6297名2015年1月至2020年2月至北京大学首钢医院行健康体检的0~3岁婴幼儿,其中男童3306名,女童2991名,采用定量超声技术检测其骨密度值,对结果进行分析。结果:6297名婴幼儿骨密度平均Z值为-0.99,轻度不足率14.2%(911/6297),中度不足率11.6%(750/6297),严重不足率19.9%(1268/6297),总不足率46.5%(2929/6297);女童骨密度值明显低于男童,女童骨密度低下检出率为56.9%(1702/2991),明显高于男童的37.1%(1227/3306),轻度、中度及重度不足率亦均高于男童。骨密度值以4~6个月组最低,0~3个月次之,6个月后骨密度值随着年龄增长逐渐增长,不足率以4~6个月组最高。结论:北京市石景山区0~3岁婴幼儿骨密度低下率较高,与性别、年龄有相关性。
Abstract
Objective:To measure the bone mineral density of infants and toddlers aged 0-3 in Shijingshan district of Beijing.Methods:A total of 6297 infants and toddlers aged 0-3 years who received physical examination at Peking University Shougang Hospital from January 2015 to February 2020 were selected, of whom there were 3306 boys and 2991 girls. Bone mineral density was measured by quantitative ultrasound. The results were then analyzed statistically.Results:The mean Z value of bone mineral density in 6297 infants and toddlers was -0.99; the mild deficiency rate was 14.2% (911/6297), moderate deficiency rate was 11.6% (750/6297), severe deficiency rate was 19.9% (1268/6297), and the total deficiency rate was 46.5% (2929/6297). The bone mineral density of girls was significantly lower than that of boys. The deficiency rate of girls was 56.9% (1702/2991), which was significantly higher than that of boys (37.1%, 1227/3306). The mild deficiency, moderate deficiency and severe deficiency rates of girls were also all higher than those of boys. The bone mineral density was the lowest in the 4-6 months group, followed by 0-3 months. After 6 months of age, the bone mineral density increased gradually with age. The deficiency rate was the highest too in the 4-6 months group.Conclusion:There is a high rate of low bone mineral density in infants and toddlers aged 0-3 years in Shijingshan district of Beijing, which is related to gender and age.
