目的:对XX地区0-6岁儿童的骨强度进行调查,为预防儿童低骨密度提供数据支持。方法:选择2014年12月-2016年1月在儿童保健门诊进行健康体检的0-6岁儿童450名,按照年龄和性别进行分组,用超声骨密度仪测定不同组别儿童的胫骨超声速率。结果:(1)男童骨密度不足16例,检出率为6.4%(16/247),女童骨密度不足32例,检出率为15.7%(32/203),组间差异具统计学意义(P<0.05);(2)<6个月,6-11个月,1-3岁,4-6岁儿童骨密度不足检出率分别为19.1%,8.3%,7.5%和7.4%,<6个月的幼儿检出骨密度不足率显著高于其他三组,组间差异具统计学意义(P<0.05)。结论:6个月内的幼儿易出现骨密度不足的现象,女童骨密度不足发生率更高,应给予针对性营养指导。
OBJECTIVE: To investigate the bone strength of 0-6 years old children in XX area and provide data support for preventing low BMD in children. METHODS: A total of 450 children aged 0-6 undergoing physical examination at Child Health Clinic from December 2014 to January 2016 were selected and divided into groups according to age and sex. The tibial ultrasonic rates in different groups of children were determined by using ultrasonic bone densitometry. Results: (1) In 16 boys with less than 16 cases of bone density, the detection rate was 6.4% (16/247) and the female bone density was less than 32 cases (15.7%, 32/203) (P <0.05). (2) The detection rates of BMD of children younger than 6 months, 6-11 months, 1-3 years and 4-6 years old were 19.1%, 8.3%, 7.5% and 7.4% The rate of BMD detection in children younger than 6 months was significantly higher than that in the other three groups, with statistical significance (P <0.05). Conclusion: The phenomenon of under-BMD is easy to occur in young children within 6 months. The incidence of under-BMD in girls is higher, and targeted nutrition guidance should be given.
