Faster eating is positively associated with body mass index in apparently healthy Japanese populations. In the present study, we examined the associations between self-reported rate of eating and visceral and subcutaneous fat areas in apparently healthy middle-aged Japanese men.
We conducted a cross-sectional study of men who participated in health checkups in Japan. We removed participants who were diagnosed with metabolic diseases by the time of their health checkups. A total of 320 subjects aged 30-64 years (mean ± standard deviation, 47.4 ± 8.6 years) were selected. We compared the associations between rate of eating and various clinical parameters including visceral and subcutaneous fat areas, using analysis of covariance (ANCOVA), which was adjusted by age and lifestyle factors such as alcohol intake, energy intake, smoking, and physical activity. Multivariate logistic regression analyses (MLRA) were performed with visceral fat area (cm(2)) as the dependent variable and independent variables that included self-reported rate of eating.
Tukey's multiple test following ANCOVA showed that self-reported rate of eating was positively associated with visceral fat area (cm(2)), but not with subcutaneous fat area (cm(2)). MLRA showed that the odds ratio of rate of eating for visceral fat area in tertile (T) 3 (>100 cm(2)) compared with T1 (≤70 cm(2)) was 1.99 (95% CI 1.40-2.90, P < 0.01), and the association remained after adjustment for the subcutaneous fat area.
The present results show that self-reported faster eating is positively associated with visceral fat accumulation, independently of subcutaneous fat accumulation, in apparently healthy Japanese men.
在看似健康的日本人群中，进食速度较快与体重指数呈正相关。本研究旨在探讨在看似健康的中年日本男性中，自我报告的进食速度与内脏和皮下脂肪面积之间的关系。
我们对参加日本健康检查的男性进行了横断面研究。我们排除了在健康检查时被诊断患有代谢疾病的参与者。共选择了 320 名年龄在 30-64 岁（平均±标准差，47.4±8.6 岁）的受试者。我们使用协方差分析（ANCOVA）比较了进食速度与各种临床参数之间的关系，包括内脏和皮下脂肪面积，该分析通过年龄和生活方式因素（如饮酒、能量摄入、吸烟和体力活动）进行了调整。使用多元逻辑回归分析（MLRA）将内脏脂肪面积（cm²）作为因变量，将包括自我报告的进食速度在内的独立变量作为自变量。
ANCOVA 后的 Tukey 多重检验显示，自我报告的进食速度与内脏脂肪面积（cm²）呈正相关，但与皮下脂肪面积（cm²）无关。MLRA 显示，与 T1（≤70cm²）相比，T3（>100cm²）的进食速度与内脏脂肪面积的比值比为 1.99（95%CI 1.40-2.90，P<0.01），且在调整了皮下脂肪面积后，该关联仍然存在。
本研究结果表明，在看似健康的日本男性中，自我报告的进食速度较快与内脏脂肪堆积呈正相关，与皮下脂肪堆积无关。
