摘要： 目的分析6～8岁骨龄段女童体质量指数(BMI)测量及体脂率状况,为针对性预防和治疗儿童肥胖提供科学依据。方法收集2022年1—7月于北部战区总医院接受肥胖筛查的968例6～8岁骨龄段女童体检资料,分析6～8岁骨龄段女童BMI、体脂率、营养学指标与肥胖率情况,采用Logistic多因素回归分析明确6～8岁骨龄段女童的肥胖危险因素。结果 6～8岁女童BMI、全身脂肪率、内脏脂肪等级比较,差异有统计学意义(F=10.196、68.327、66.584,P＜0.001),其中 6～8岁女童BMI平均值与7～8岁女童全身脂肪率平均值高于正常范围。6～8岁女童25-(OH)D平均值低于正常范围,6～8岁女童超重率分别为19.50%、18.21%、15.95%,肥胖率分别为9.75%、12.35%、15.95%。Logistic多因素回归分析结果显示,出生体重≥4.0kg(OR=1.962,95%CI:1.292～2.979)、高脂高热量进食频率＞3次/周(OR=1.432,95%CI:1.172～1.749)、进食甜食频率＞3次/周(OR=2.670,95%CI:1.170～6.093)、进食速度＜15min/餐(OR=1.366,95%CI:1.108～1.685)、户外活动频率＜30min/d(OR=2.083,95%CI:1.162～3.736)、父母不了解或略了解营养学(OR=1.721,95%CI:1.129～2.623)是6～8岁女童肥胖的独立危险因素(P＜0.05)。结论 6～8岁骨龄段女童肥胖率均较高,需要通过科学搭配饮食、合理运动及引导父母提升营养学知识水平等方面进行改善。

Abstract: Objective To analyze the measurement of body mass index (BMI) and body fat percentage in girls aged 6 to 8 years,in order to provide a scientific basis for the prevention and treatment of childhood obesity. Methods The medical examination data of 968 girls with bone age of 6 - 8 years who underwent obesity screening in General Hospital of Northern Quarter Command from January 2022 to July 2022 were retrospectively analyzed. BMI, body fat percentage, nutritional indicators, and obesity rate of girls with bone age of 6 - 8 years were analyzed.Multivariate Logistic regression analysis was used to identify the risk factors for obesity in girls with bone age of 6 - 8 years old. Results BMI, body fat percentage and visceral fat grade of girls aged 6 - 8 years followed an increasing trend with age: 6 years old < 7 years old < 8 years old (F=10.196, 68.327, 66.584, P<0.001). The average BMI of girls aged 6 - 8 years and the average body fat percentage of girls aged 7 - 8 years old were higher than the normal range. Additionally, the average value of 25-hydroxy vitamin D[25-(OH)D] in girls aged 6 - 8 years was lower than the normal range. The overweight rates of girls aged 6,7 and 8 years were 19.50%, 18.21%, and 15.95%, respectively, and the obesity rates were 9.75%, 12.35%, and 15.95%, respectively. Furthermore, the Logistic multivariate regression analysis revealed that birth weight ≥ 4.0kg (OR=1.962,95%CI: 1.292 - 2.979), eating frequency of high-fat and high-calorie > 3times/week (OR=1.432, 95%CI: 1.172 - 1.749),frequency of sweet food >3times/week (OR=2.670, 95%CI:1.170 - 6.093), eating speed < 15min/meal (OR=1.366, 95%CI:1.108 - 1.685), outdoor activity frequency <30min/day (OR=2.083, 95%CI:1.162 - 3.736), and parents lack of knowledge or with limited understanding of nutrition (OR=1.721, 95%CI:1.129 - 2.623) were independent risk factors for obesity in girls aged 6 - 8 years old (P<0.05). Conclusion The obesity rate of girls with bone age of 6 - 8 years old is high and should be addressed through a scientific diet, reasonable exercise, and educating parents to improve their knowledge of nutrition.
