This cross-sectional study investigated the relationship between eating speed and fat accumulation in Japanese non-obese adults.
In total, 381 non-obese participants aged 35-74 years underwent a health checkup including fat distribution. All participants underwent magnetic resonance imaging to quantify visceral fat area (VFA) and subcutaneous fat area (SFA). Information on eating speed was obtained using a self-administrated questionnaire.
The numbers of participants with self-reported behavior of eating slowly, medium, or quickly were 24 (6.3%), 180 (47.2%), and 177 (46.5%), respectively. The prevalence of VFA ≥100 cm2 was higher in the eating quickly group than in the eating slowly (p<0.05) or medium groups (p<0.05). On the other hand, no significant differences in SFA ≥100 cm2 were observed between groups. In addition, multiple stepwise regression analysis showed that eating quickly was positively correlated with VFA (standard β=0.068, p<0.05), but not with SFA.
Although eating quickly was positively correlated with bigger VFA in Japanese non-obese adults, no associations were found between eating speed and SFA.
本横断面研究调查了日本非肥胖成年人的进食速度与脂肪堆积之间的关系。
总共381名年龄在35 - 74岁的非肥胖参与者接受了包括脂肪分布在内的健康检查。所有参与者均接受磁共振成像以量化内脏脂肪面积（VFA）和皮下脂肪面积（SFA）。通过自我管理问卷获取进食速度信息。
自我报告进食慢、适中或快的参与者人数分别为24人（6.3%）、180人（47.2%）和177人（46.5%）。进食快的组中VFA≥100 cm²的患病率高于进食慢的组（p<0.05）或进食适中的组（p<0.05）。另一方面，各组之间SFA≥100 cm²未观察到显著差异。此外，多元逐步回归分析显示进食快与VFA呈正相关（标准β=0.068，p<0.05），但与SFA无关。
尽管在日本非肥胖成年人中进食快与更大的VFA呈正相关，但未发现进食速度与SFA之间存在关联。
