Normal-weight obesity is defined as having high body fat but a normal body mass index (BMI). This study examined whether there are differences in habitual physical activity and diet between individuals with normal-weight obesity and obese or non-obesity. This study included 143 males aged 65-75 years, and they were classified into the following three groups according to BMI and visceral fat area (VFA): obese group (n = 27 (BMI: ≥25 kg/m and VFA: ≥100 cm)), normal-weight obese group (n = 35 (BMI: <25 kg/m and VFA: ≥100 cm)) and non-obese group (n = 81 (BMI: <25 kg/m and VFA < 100 cm)). Lowered high-density lipoprotein cholesterol and elevated triglyceride and alanine transaminase were observed in the normal-weight obese group than in the non-obese group (all for ≤ 0.04, effect size ≥ 0.50). No differences were found in physical activity and dietary habits between non-obese and normal-weight obese groups (all for > 0.05). Although impaired lipid and liver function parameters were observed in older males with normal-weight obesity compared with older males with non-obesity, physical activity and dietary profiles in themselves were not shown these differences in the present study.
正常体重肥胖定义为体脂高但身体质量指数（BMI）正常。本研究旨在探讨正常体重肥胖者与肥胖或非肥胖者之间的日常体力活动和饮食是否存在差异。该研究纳入了 143 名年龄在 65-75 岁的男性，根据 BMI 和内脏脂肪面积（VFA）将他们分为以下三组：肥胖组（n = 27（BMI：≥25 kg/m 且 VFA：≥100 cm））、正常体重肥胖组（n = 35（BMI：<25 kg/m 且 VFA：≥100 cm））和非肥胖组（n = 81（BMI：<25 kg/m 且 VFA < 100 cm））。与非肥胖组相比，正常体重肥胖组的高密度脂蛋白胆固醇降低，甘油三酯和丙氨酸转氨酶升高（均为 ≤ 0.04，效应大小≥0.50）。非肥胖组和正常体重肥胖组之间的体力活动和饮食习惯没有差异（均为 > 0.05）。尽管与非肥胖的老年男性相比，正常体重肥胖的老年男性存在脂质和肝功能参数受损的情况，但在本研究中，体力活动和饮食模式本身并未显示出这些差异。
