The Czech Republic lacks body composition data for women. Therefore, the purpose of the study was to analyze body composition [body fat mass (BFM), fat-free mass (FFM), body fat percentage (%BFM) and visceral adipose tissue (VAT)] and to evaluate the changes that occur with aging in women aged 18-89 years. We also analyzed anthropometric characteristics of study participants and developed age-specific percentile curves for body composition parameters.
A cross-sectional, non-randomized study was conducted with a sample of 1,970 apparently healthy Czech women. Body composition was measured using a direct segmental multi-frequency bioelectrical impedance analysis (BSM-BIA).
The mean BFM was 19.7 ± 8.9 kg, and BFM reached its peak in women over 70, at 27.6 ± 8.8 kg. There was a strong correlation between BFM and age (r = 0.61; r (2) = 0.37). Fifty percent of the women in the study had a BFM between 13.0 and 25.0 kg. The %BFM (r = 0.69; r (2) = 0.47) and VAT (r = 0.88; r (2) = 0.77) were also significantly associated with age. The reference range for %BFM was 22.0-35.6 % (25th-75th percentile). The mean FFM was 45.8 ± 5.5 kg, and FFM decreased with age (r = -0.27; r (2) = 0.07).
The results presented in this study showed a statistically significant increase in BFM, %BFM and VFA as age increased, and the values reached their peak in women over 70. Even when FFM decreased slightly with age, body weight increased because of the increase in BFM.
捷克共和国缺乏女性人体成分数据。因此，本研究的目的是分析 18-89 岁女性的人体成分[体脂肪量（BFM）、去脂体重（FFM）、体脂肪百分比（%BFM）和内脏脂肪组织（VAT）]，并评估随年龄增长而发生的变化。我们还分析了研究参与者的人体测量特征，并为身体成分参数制定了特定年龄的百分位数曲线。
采用横断面、非随机研究，对 1970 名捷克健康女性进行样本分析。使用直接分段多频生物电阻抗分析（BSM-BIA）测量身体成分。
平均 BFM 为 19.7 ± 8.9 kg，BFM 在 70 岁以上的女性中达到峰值，为 27.6 ± 8.8 kg。BFM 与年龄呈强相关（r = 0.61；r（2）= 0.37）。研究中有 50%的女性 BFM 在 13.0-25.0 kg 之间。%BFM（r = 0.69；r（2）= 0.47）和 VAT（r = 0.88；r（2）= 0.77）也与年龄显著相关。%BFM 的参考范围为 22.0-35.6%（25 至 75 百分位）。平均 FFM 为 45.8 ± 5.5 kg，FFM 随年龄下降（r = -0.27；r（2）= 0.07）。
本研究结果表明，随着年龄的增长，BFM、%BFM 和 VFA 呈统计学意义上的显著增加，在 70 岁以上的女性中达到峰值。即使 FFM 随年龄略有下降，由于 BFM 的增加，体重也会增加。
