The objective of this study was to evaluate the effects of a comprehensive overweight intervention program, which utilizes hot bathing, on overweight, community-dwelling middle-aged and older adults in a randomized controlled trial.
The program was carried out in a hot bath facility and included 66 community-dwelling middle-aged and older Japanese adults (mean age 61.6 years, SD 7.5, 77.3% were women). The participants were randomly assigned to an exercise, diet and hot bathing intervention group (group A), exercise and diet intervention group (group B), a hot-bathing intervention group (group C) and a control group (group D). The participants in groups A and B participated in a comprehensive intervention program (including exercise and diet classes) twice a week for 3 months, and groups A and C had hot bathing.
After 3 months, the participants in group A showed a reduction in weight, abdominal circumference, body mass index and body fat percentage compared with the other intervention groups. And the lower extremity function (i.e. walking speed) had greater improvement in the participants in groups A and B compared with groups C and D. In group C, in which only hot bathing was the intervention, there were no significant improvements in measurement items.
Our study provides preliminary evidence that a comprehensive intervention program, including hot bathing, is useful for community residents with a tendency toward overweight.
本研究旨在评估综合超重干预计划对超重、社区居住的中年和老年人的影响，这是一项随机对照试验。
该计划在热水浴设施中进行，包括 66 名社区居住的中年和老年日本成年人（平均年龄 61.6 岁，标准差 7.5，77.3%为女性）。参与者被随机分配到运动、饮食和热水浴干预组（A 组）、运动和饮食干预组（B 组）、热水浴干预组（C 组）和对照组（D 组）。A 组和 B 组的参与者每周参加两次综合干预计划（包括运动和饮食课程），持续 3 个月，A 组和 C 组进行热水浴。
3 个月后，与其他干预组相比，A 组的参与者体重、腰围、体重指数和体脂百分比均有所下降。A 组和 B 组的下肢功能（即步行速度）较 C 组和 D 组有更大的改善。在仅接受热水浴干预的 C 组中，测量项目没有显著改善。
我们的研究提供了初步证据，表明包括热水浴在内的综合干预计划对有超重倾向的社区居民是有用的。
