To analyze the level of physical activity (kcal/week) needed to prevent excess visceral fat in postmenopausal women.
The sample included 239 women with a mean age of 57.2 years. Visceral fat area (VFA) was measured by octopolar bioelectrical impedance, and physical activity, by the long version IPAQ. ROC Curves (Receiver Operating Characteristic) were drawn, and a 95% confidence interval was used.
The areas under the ROC curve for moderate physical activity and walk proved to be significant. Weekly expenditure of 1,601 kcal in walking, or 2,283 kcal in moderate physical activity were identified as good cutoff values to prevent excess VFA.
Mild to moderate physical activity, with a caloric expenditure between 1,601 and 2,283 kcal/week, prevents excess central adiposity in postmenopausal women.
分析绝经后女性预防内脏脂肪过多所需的体力活动水平（千卡/周）。
样本包括239名平均年龄为57.2岁的女性。通过八极生物电阻抗测量内脏脂肪面积（VFA），通过长版国际体力活动问卷（IPAQ）测量体力活动。绘制ROC曲线（受试者工作特征曲线），并使用95%置信区间。
中等强度体力活动和步行的ROC曲线下面积具有显著性。步行每周消耗1601千卡，或中等强度体力活动每周消耗2283千卡被确定为预防VFA过多的良好临界值。
轻度至中度体力活动，每周热量消耗在1601至2283千卡之间，可预防绝经后女性腹部脂肪过多。
