摘要: 目的 分析儿童青少年骨矿物质含量(BMC)与肥胖之间的关系,为预防儿童青少年骨质疏松提供更有力的依据。方法 于2017—2020年以整群随机抽样的方法从银川市随机抽取1 578名儿童青少年作为研究对象,进行问卷调查、体格检查、骨矿物质含量测定,采用二元Logistic回归分析不同定义的肥胖指标与骨矿物质含量之间的关系。 结果 不同指标体重指数(BMI),腰围(WC),腰围身高比(WHtR)和体脂百分比(FMP)肥胖组的BMC均高于正常组(P<0.01);男、女生不同肥胖指标与BMC均呈正相关(P<0.01),其中男生WC,女生BMI与BMC的相关性最高(r=0.749和0.684);二元Logistic回归分析结果显示,在调整年龄后发现,对男生中,以FMP,WHtR定义的肥胖与BMC增加呈正相关(FMP:OR=1.53,95%CI:1.04~2.27, WHtR:OR=4.39,95%CI:1.55~12.44);女生中,以FMP定义的肥胖与BMC增加呈正相关(OR=3.46,95%CI:1.59~7.51)。结论 基于FMP,WHtR分别定义的肥胖类型对儿童青少年预防骨质疏松有一定的公共卫生价值,但过度肥胖可能会造成骨骼损伤。

Abstract: Objective To analyze the relationship between body mineral content (BMC) and obesity in children and adolescents, so as to provide more powerful basis for preventing osteoporosis in children and adolescents. Methods A total of 1 578 children and adolescents were randomly selected from Yinchuan city by cluster sampling from 2017 to 2020, and conducted questionnaire survey. Their physical examination and bone mineral content were measured. The relationship between obesity of different definitions and bone mineral content was analyzed by binary Logistic regression. Results BMC of obese children at different body mass index (BMI), waist circumference (WC), waist height ratio (WHtR) and percentage of body fat (FMP) groups were significantly higher than that of normal group (P<0.01). There was a positive correlation between BMC and different obesity indicators in boys and girls (P <0.01). WC in boys and BMI in girls had the highest correlation with BMC (r=0.749, 0.684). Binary Logistic regression analysis showed that after adjusting for age, it was found that obesity defined by FMP and WHtR was significantly associated with the increase of BMC in boys (FMP:OR=1.53, 95%CI:1.04 - 2.27; WHtR:OR=4.39, 95%CI:1.55 - 12.44). For girls, obesity defined by FMP was significantly associated with the increase of BMC (OR=3.46, 95%CI:1.59 - 7.51). Conclusion Obesity defined by FMP and WHtR have a certain public health value for children and adolescents to prevent osteoporosis, but excessive obesity may cause bone injury.
