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.
