本研究旨在确定不同性别和肥胖状况的咀嚼能力和饮食行为是否存在差异。 48 名（24 名男性；24 名女性）非肥胖和肥胖前期的年轻人在年龄、性别和牙齿健康方面进行了匹配。使用三因素饮食问卷 (TFEQ) 评估饮食行为，并使用肌电图 (EMG) 测量吃 152 克米饭时的咀嚼性能。根据 TFEQ，与非肥胖参与者相比，肥胖前参与者的去抑制水平显着更高（男性 P < 0.05；女性 P < 0.01）。咀嚼性能的微观结构因性别而存在显着差异，但不因肥胖状况而存在显着差异。与女性相比，男性的咬合大小（P < 0.05）、咀嚼能力（P < 0.001）和进食速度更快（P < 0.05）。女性习惯性地比男性咀嚼更多（P < 0.05）并且进餐时间更长（P < 0.01）。男性的进食率与去抑制评分呈正相关（r = 0.490，P < 0.05）。咬合大小（r = -0.449，非肥胖者 P < 0.05）和咀嚼力（非肥胖者 r = -0.581，P < 0.01，肥胖前 r = -0.446，P < 0.05）与去抑制评分呈负相关。结果表明，性别以及肥胖对饮食反应的影响可以用咀嚼能力来解释。因此，旨在减慢摄入速度的针对性别的干预和咨询可能是肥胖者有希望的行为治疗方法。 (C) 2014 Elsevier Inc. 保留所有权利。
This study aimed to determine whether there might be differences in masticatory performance and eating behaviors by gender and obesity status. Forty eight (24 males; 24 females) non-obese and pre-obese young adults were matched for age, gender, and dental health. Eating behaviors were assessed using the Three-Factor Eating Questionnaire (TFEQ), and chewing performance while eating 152 g of boiled rice was measured using electromyography (EMG). Compared with non-obese participants, pre-obese participants had significantly higher levels of disinhibition according to the TFEQ (P < 0.05 for males; P < 0.01 for females). Microstructures of chewing performance were significantly different by gender but not by obesity status. Males had a greater bite size (P < 0.05), greater chewing power (P < 0.001) and a faster eating rate (P < 0.05) than females. Females habitually chewed more (P < 0.05) and had a longer meal duration (P < 0.01) than males. Eating rate was positively associated with disinhibition (r = 0.490, P < 0.05) score in males. Bite size (r = -0.449, P < 0.05 for non-obese) and chewing power (r = -0.581, P < 0.01 for non-obese and r = -0.446, P < 0.05 for pre-obese) were negatively associated with disinhibition score. Results suggest that the effects of gender and, in part, obesity on eating responses may be explained as chewing performance. Therefore, gender-specific interventions and counseling aimed at slowing the rate of ingestion could be promising behavioral treatments for obese persons. (C) 2014 Elsevier Inc. All rights reserved.
