摘要:
目的 了解海南省小学生的饮奶行为及其骨密度水平,并探究骨密度与饮奶行为的相关性,为促进儿童青少年骨骼的健康发育提供科学依据。 方法 于2021年11月,采用分层整群随机抽样方法,分别从海南省三亚市和白沙县抽取三至五年级696名小学生进行调查,包括人口学特征、奶及奶制品的摄入情况、不良饮食行为、身体活动和睡眠情况,采用双能X线骨密度测量仪测量学生右侧前臂远端1/3处的骨密度。采用t检验比较不同饮奶行为小学生的骨密度,采用多元线性回归分析饮奶量与骨密度的相关性。 结果 有25.3%小学生每日饮奶,13.9%小学生日均饮奶量≥300 g。小学生右侧前臂远端1/3处的骨密度平均为(0.237±0.041)g/cm2。每日饮奶组的小学生骨密度大于非每日饮奶组[(0.250±0.037)(0.204±0.034)g/cm2;t=15.00,P < 0.01],日均饮奶量≥300 g的小学生骨密度大于日均饮奶量 < 300 g的学生[(0.284±0.036)(0.229±0.037)g/cm2;t=13.48,P < 0.01]。多元线性回归分析显示,小学生日均饮奶量与骨密度呈正相关(β=0.020,t=21.46,P < 0.01)。 结论 小学生饮奶状况不佳,饮奶行为对骨密度有积极影响。应进行有效的饮奶干预促进儿童骨骼发育。 Abstract:Objective To investigate the milk-drinking behavior and bone mineral density level of pupils in Hainan Province, and to explore the correlation between bone mineral density and milk-drinking behavior, in order to provide scientific basis for promoting the healthy development of bones in children and adolescents. Methods In November 2021, a cross-sectional survey including demographic characteristics, milk intake, unhealthy eating behavior, physical activity and sleep was conducted among 696 students from grades 3 to 5 in Sanya and Baisha, Hainan by stratified cluster random sampling, and bone mineral density at the distal 1/3 of the right forearm was measured by dual-energy X-ray absorptiometry. t-test was used to compare the differences in bone mineral density among different milk-drinking behaviors of pupils, and multiple linear regression was used to analyze the correlation between milk consumption and bone mineral density. Results About 25.3% students consumed milk daily and 13.9% consumed ≥300 g of milk daily. The mean bone mineral density at the distal 1/3 of the right forearm was (0.237±0.041)g/cm2. The bone mineral density was greater in the group with daily milk intake than in the group without daily milk intake [(0.250±0.037)(0.204±0.034)g/cm2, t=15.00, P < 0.01], and the bone mineral density was greater in the group with daily average milk intake ≥300 g than in the group with daily average milk intake < 300 g [(0.284±0.036)(0.229±0.037)g/cm2, t=13.48, P < 0.01]. Multiple linear regression analysis showed that daily average milk intake was positively correlated with bone mineral density, with a correlation coefficient (β=0.020, t=21.46, P < 0.01). Conclusion Milk consumption among pupils is inadequate, and milk-drinking behavior has a positive impact on bone mineral density, so effective milk-drinking intervention should be carried out to promote children's bone development. -
