纳西族成人各项肥胖指标与体脂率的关系

摘要：

目的 探讨纳西族各项肥胖指标与体脂率的关系。  方法 选取云南省丽江市玉龙县687名18~90岁成年纳西族人，运用人体测量法和生物电阻抗法测量其体重、身高、胸围、腰围、臀围、肱二头肌皮褶、肱三头肌皮褶、肩胛下皮褶、髂嵴上皮褶、髂前上棘皮褶、体质量指数（BMI）、内脏脂肪等级和体脂率等指标，并将各项指标分别与体脂率进行统计分析。  结果 纳西族成人的平均体脂率男性为正常水平，女性属于肥胖。按照内脏脂肪等级为标准，纳西族男性和女性均在正常范围内。根据腰围的判断标准，纳西族男性腰围在正常范围内，而女性腰围属于腹型肥胖。相关分析表明，纳西族成人的体重、胸围、腰围、臀围、肱二头肌皮褶、肱三头肌皮褶、肩胛下皮褶、髂嵴上皮褶、髂前上棘皮褶、BMI、内脏脂肪等级与体脂率均成正相关。纳西族男性内脏脂肪等级与体脂率相关性最强，其次是BMI；纳西族女性胸围与体脂率相关性最强，其次是腰围。  结论 纳西族成人各项肥胖指标均与体脂率成正相关，相关程度存在性别、地区和民族差异。

Abstract:

Objective  To explore the relationship between obesity indexes and body fat rate in Naxi adults.   Methods  A total of 687 Naxi adults aged between 18 and 90 were selected from Yulong County, Lijiang City, Yunnan Province. Body weight, height, chest circumference, waist circumference, hip circumference, biceps skinfold, triceps skinfold, subscapular skinfold, suprailiac skinfold, anterior superior spine skinfold, body mass index（BMI）,visceral fat index and body fat percentage were measured by anthropometry and bioelectrical impedance analysis. And the indexes and body fat percentage were statistically analyzed.   Results  The average body fat percentage of Naxi men was normal, while the women was obese. According to the criteria of visceral fat index, the average visceral fat index of Naxi men and women was within the normal range. According to the waist circumference, the waist circumference of Naxi men was within the normal range, while the waist circumference of women belonged to abdominal obesity. Correlation analysis showed that body weight, chest circumference, waist circumference, hip circumference, biceps skinfold, triceps skinfold, subscapular skinfold, suprailiac skinfold, anterior superior iliac spine skinfold, BMI, visceral fat index were positively correlated with body fat percentage among Naxi adults. There was the strongest correlation between visceral fat index and body fat percentage in Naxi men, followed by BMI; Naxi women’s chest circumference and body fat percentage, followed by waist circumference.   Conclusion  All the obesity indexes of Naxi adults are positively correlated with body fat percentage, and there are gender, regional and ethnic differences in the degree of correlation.
