甘肃省0～3岁婴幼儿膳食因素与骨密度水平相关分析

Analysis on the correlation between dietary factors and bone mineral density in 0-3-year-old infants in Gansu

目的研究膳食因素对0~3岁婴幼儿骨密度水平的影响.方法选取2016年1月-2017年10月于该院儿保门诊进行健康体检的0~3岁婴幼儿3 759例.采用定量超声技术,测定婴幼儿左侧胫骨的超声速度(SOS),并通过调查问卷的方式调查儿童膳食状况.结果婴幼儿未补钙(2岁以上)、维生素D补充较少、纯母乳喂养/经常喂母乳是骨密度不足的危险因素(均P<0.05);经常吃肉类(7个月~2岁以内)、水果(2岁以上)是骨密度不足的保护因素(均P<0.05).结论膳食摄入对婴幼儿骨密度有显著影响,应密切关注膳食摄入情况,以期更好的促进婴幼儿期骨骼健康.

Objective To research the effect of dietary factors on bone mineral density ( BMD) of 0-3-year-old infants. Methods A total of 3 759 infants aged 0-3 years old receiving healthy physical examination in Outpatient of Child Health Care in Gansu Provincial Maternal and Child Health Care Hospital from January 2016 to October 2017 were selected, quantitative ultrasound was used to detect speed of sound (SOS) of left tibia, dietary status was surveyed by a questionnaire. Results The risk factors of bone density deficiency included lack of calcium supplementation ( more than 2 years old), deficiency of vitamin D supplementation, exclusive breastfeeding/frequent breastfeeding (P<0. 05). Eating meat frequenctly ( from 7 months to less than 2 years old) were protective factors of bone density deficiency (P< 0. 05 ). Conclusion Dietary intake has significanl impact on BMD of infants, more attention should be paid to dietary intake to further promote bone health of infants.
