To investigate the effects of monthly feedback of changes in visceral fat area (VFA) as measured by dual bioelectrical impedance analysis method and the importance of VFA in individuals with obesity.
Thirty-eight Japanese patients with obesity underwent VFA measurements. The feedback group was given feedback on VFA measurements each month for 4 months. The control group underwent VFA measurements at the beginning and end of the study but was not informed of the results. All the study participants completed eating behaviour and weight efficacy lifestyle questionnaires.
Mean age was 53.9 (14.3) years; mean body mass index was 30.6 (4.3) kg m. At the 4-month follow-up, there was no significant difference in VFA reduction between the control and feedback groups (-4.4% vs. -3.0%; 95% CI, -3.8 to 5.5). In post-hoc analysis using the overall group irrespective of allocation, changes of eating style were significantly associated with a reduction in VFA at 4 months (p = 0.034).
Monthly feedback on changes in VFA does not reduce VFA. More frequent feedback may be required. In post-hoc analysis, changes of eating style were associated with a reduction in VFA.
探讨采用双生物电阻抗分析法测量的内脏脂肪面积（VFA）每月变化反馈的效果以及VFA在肥胖个体中的重要性。
38名日本肥胖患者接受了VFA测量。反馈组在4个月内每月都收到VFA测量结果的反馈。对照组在研究开始和结束时进行VFA测量，但未被告知结果。所有研究参与者均完成了饮食行为和体重效能生活方式问卷。
平均年龄为53.9（14.3）岁；平均体重指数为30.6（4.3）kg/m²。在4个月的随访中，对照组和反馈组的VFA减少量无显著差异（-4.4%对-3.0%；95%CI，-3.8至5.5）。在不考虑分组的总体组的事后分析中，4个月时饮食方式的改变与VFA的减少显著相关（p = 0.034）。
每月对VFA变化进行反馈并不能减少VFA。可能需要更频繁的反馈。在事后分析中，饮食方式的改变与VFA的减少有关。
