日本年轻和老年女性躯干肌内脂肪组织含量与饮食摄入和饮食行为的关系：一项初步研究
The Associations of Trunk Intramuscular Adipose Tissue Content with Dietary Intake and Eating Behavior in Younger and Older Japanese Women: A Pilot Study.
摘要(中文译文)
肌肉内脂肪组织（IntraMAT）是积聚在骨骼肌内的异位脂肪。男性躯干IntraMAT含量与膳食摄入之间的关系已被证实随年龄而变化，但女性中的这种关系尚不明确。因此，本研究探讨了年轻女性和老年女性IntraMAT含量与膳食摄入及饮食行为之间的关联。本横断面研究纳入了24名18至23岁的年轻女性（体质指数（BMI）：20.5 ± 2.3 kg/m²）和25名66至77岁的老年女性（BMI：21.7 ± 2.5 kg/m²）。IntraMAT含量通过第三腰椎水平的磁共振成像进行评估。膳食摄入采用自填式饮食史问卷进行评估。饮食行为通过肥胖指南（2022年）中饮食行为问卷计算的评分进行评估。同时还测量了与代谢综合征相关的血液指标。在年轻组中，IntraMAT含量与高密度脂蛋白胆固醇和胰岛素显著相关（r = -0.411和0.415，P < 0.05）。在老年组中，IntraMAT含量与蛋白质供能比、饥饿感及饮食行为总分显著相关（r = -0.410至0.412，P < 0.05）。老年组躯干IntraMAT含量可能与膳食蛋白质摄入及饮食行为有关。
Abstract
: Intramuscular adipose tissue (IntraMAT) is the ectopic fat which accumulates within skeletal muscle. The relationship between trunk IntraMAT content and dietary intake was shown to differ with age in men, but it remains unclear the relationship in women. Therefore, the present study investigated the associations of IntraMAT content with dietary intake and eating behavior in younger and older women. : This cross-sectional study involved 24 young women aged 18 to 23 years (body mass index (BMI): 20.5 ± 2.3 kg/m) and 25 older women aged 66 to 77 years (BMI: 21.7 ± 2.5 kg/m) who participated. IntraMAT content was assessed by magnetic resonance imaging at the height of the 3rd lumbar vertebra. Dietary intake was evaluated using a self-administered diet history questionnaire. Eating behavior was evaluated by scores calculated using the eating behavior questionnaire in the guideline for obesity (2022). Blood properties related to metabolic syndrome were also measured. : In the younger group, IntraMAT content was significantly related to HDL cholesterol and insulin (r = -0.411 and 0.415, < 0.05). In the older group, IntraMAT content significantly correlated with the percentage of energy from protein, sense of hunger, and total eating behavior (r = -0.410 to 0.412, < 0.05). : Trunk IntraMAT content may be related to dietary protein intake and eating behavior in the older group.
