Excessive adipocyte growth during the pubertal transition predisposes to the development and persistence of obesity in adulthood. Visceral accumulation of body fat is particularly disadvantageous when it is correlated with insulin resistance, secondary hyperinsulinaemia, dysglicaemia, and atherogenic dyslipidemia.
The aim of this study was to conduct a nutritional status assessment and body composition analysis in 13-year-old adolescents of both genders with visceral fat accumulation (WC ≥ 90th percentile) and different BMI values.
The evaluation of state of nutrition of 1,738 Polish boys (n = 882) and girls (n = 856) aged 13 was done based on anthropometric measurements and calculated BMI (body mass index), WC (waist circumference) and WHtR indices (waist-to-height ratio). Taking into consideration the value of WC ≥ 90 pc, 353 people were designated (20.3 % of the total) with visceral obesity (but with various BMI), whose body composition was examined by the method of bioelectric impedance analysis (BIA). A total of 249 adolescents of both sexes (70.5% of the selected, 102 boys and 147 girls) and their parents agreed to the study.
In adolescents with visceral obesity a significant change of body content was ascertained depending on the value of the BMI. Even in the people with a proper value of the BMI, a significantly higher than standard increase of the percentage of total body fat (TBF) and decrease of both the percentage of body lean (BL) and the content of total body water (TBW) in the body was observed. The values of the BMI, WC and WHtR in adolescents were significantly correlated with each other as well as with TBF, BL and TBW, and the strength of correlation was dependent on sex.
The state of nutrition in adolescents with visceral obesity, even with a proper BMI, might contribute to the development of a metabolic syndrome.
青春期过渡期间脂肪细胞过度生长易导致成年期肥胖的发生和持续。当体脂在内脏的蓄积与胰岛素抵抗、继发性高胰岛素血症、血糖异常和致动脉粥样硬化血脂异常相关时，尤其不利。
本研究旨在对13岁内脏脂肪蓄积（腰围≥第90百分位数）且BMI值不同的青少年进行营养状况评估和身体成分分析。
基于人体测量以及计算得出的BMI（体重指数）、腰围（WC）和腰高比（WHtR）指数，对1738名13岁波兰男孩（n = 882）和女孩（n = 856）的营养状况进行评估。考虑到WC≥第90百分位数，指定353人（占总数的20.3%）患有内脏性肥胖（但BMI各异），通过生物电阻抗分析（BIA）方法对其身体成分进行检测。共有249名青少年（占所选青少年的70.5%，其中102名男孩和147名女孩）及其父母同意参与研究。
在内脏性肥胖青少年中，根据BMI值确定身体成分有显著变化。即使BMI值正常的人群，也观察到全身脂肪（TBF）百分比显著高于标准增加量，而身体瘦组织（BL）百分比和全身水含量（TBW）均降低。青少年的BMI、WC和WHtR值彼此之间以及与TBF、BL和TBW均显著相关，且相关强度取决于性别。
内脏性肥胖青少年的营养状况，即使BMI正常，也可能促使代谢综合征的发生。
