背景:肥胖,尤其是腹部肥胖,与代谢和其他健康风险密切相关。肥胖的诊断和评估在临床和常规预防实践中很重要。从风险的角度来看,不仅要区分脂肪组织的堆积区域,也是它的类型。
目的:本研究的目的是使用一种新型的便携式腹部生物阻抗分析仪,用于腹部脂肪组织区域,作为一组选定志愿者的身体结构评估的一部分,重点是皮下和内脏脂肪组织的分化,并评估其在实践中的有效性。
方法:使用便携式腹部生物阻抗分析仪Yscope(PA-BIA)结合生物阻抗装置InBody970(高频生物电阻抗/HF-BIA)分析身体成分。83名年龄为24.92±7.24岁的男女志愿者参加了研究。
结果:性别之间的腹部脂肪没有显着差异,女性达到平均值2.01±1.14公斤,男性2.22±1.60公斤(p>0.05)。性别分化表现在内脏脂肪(p<0.01)和内脏脂肪面积(p<0.01),女性的价值低于男性。在皮下脂肪的情况下,我们发现价值观与性别相反的趋势,在男性获得较低价值的地方,但差异无统计学意义(p>0.05)。内脏脂肪与腹部脂肪(r=0.86)和腰围(r=0.85)的相关性最大,皮下脂肪与腹部脂肪(r=0.93)和体脂质量(r=0.93)的正相关最强。
结论:PA-BIA结合HF-BIA可以确定腹部皮下和内脏脂肪的代表,传统的MFS-BIA方法不允许。在评估身体成分时,确认了显著的性别差异,这是影响与性别有关的不同健康风险的重要因素,以及在身体不同部位定位和积累的不同类型的脂肪组织的代表性。
BACKGROUND: Obesity, especially abdominal obesity, is strongly correlated with metabolic and other health risks. Diagnosis and assessment of obesity is important in clinical and routine preventive practice. From the point of view of risk, it is necessary to distinguish not only the area of fat tissue accumulation, but also its type.
OBJECTIVE: The aim of the study was to use a new portable abdominal bioimpedance analyzer, which is intended for the area of abdominal adipose tissue, as part of the evaluation of the body structure of a selected group of volunteers with a focus on the differentiation of subcutaneous and
visceral adipose tissue and to assess its usefulness in practice.
METHODS: Body composition was analyzed using a portable abdominal bioimpedance analyzer Yscope (PA-BIA) in combination with a bioimpedance device InBody 970 (high-frequency bioelectrical impedance/HF-BIA). Eighty-three volunteers at the age of 24.92±7.24 years with representation of both sexes participated in the study.
RESULTS: Abdominal fat did not differ significantly between the sexes, women reached an average value of 2.01±1.14 kg, men 2.22±1.60 kg (p>0.05). Gender differentiation was manifested in the case of
visceral fat (p<0.01) and
visceral fat area (p<0.01), the values of which were lower in women than in men. In the case of subcutaneous fat, we found the opposite trend of values in relation to gender, where lower values were achieved by men, but there were no significant differences (p>0.05).
Visceral fat was most correlated with abdominal fat (r=0.86) and waist circumference (r=0.85), subcutaneous fat had the strongest positive correlations with abdominal fat (r=0.93) and with body fat mass (r=0.93).
CONCLUSIONS: PA-BIA in combination with HF-BIA makes it possible to determine the representation of subcutaneous and
visceral fat in the abdominal area, which the conventional MFS-BIA method does not allow. When evaluating body composition, significant gender differentiation is confirmed, which is an important factor affecting different health risks related to gender and the representation of different types of fat tissue localized and accumulated in different parts of the body.
