研究发现，餐前喝水可以减少非肥胖老年人的能量摄入量。然而，目前尚不清楚这种影响在超重和肥胖的老年人中是否明显，这一群体将受益于改善能量摄入调节的策略。我们的目的是确定餐前喝水是否会减少超重和肥胖的老年人的膳食能量摄入。24名超重和肥胖成年人(体重指数=34.3±1.2)，平均年龄(61.3±1.1)岁，在两个随机分配的场合提供随意的标准化早餐。在进餐前30分钟，受试者被给予500毫升的水预负荷或不预负荷。每顿饭的能量摄入量都是秘密测量的。水预负荷条件下的膳食能量摄入量显著低于无预负荷条件下的膳食能量摄入(分别为500±32vs574±38；P=0.004)，约减少13%的膳食能量摄入。水预负荷后膳食能量摄入减少的百分比与性别、年龄、体重指数或习惯性每日用水量无关(均P>；0.05)。鉴于老年人超重和肥胖的高流行率，未来的研究应该确定餐前喝水是否是老年人有效的长期体重控制策略。
Water consumed before a meal has been found to reduce energy intake among nonobese older adults. However, it is unknown whether this effect is evident among overweight and obese older adults, a population who would benefit from strategies to improve energy intake regulation. Our purpose was to determine whether premeal water consumption reduces meal energy intake in overweight and obese older adults. Twenty-four overweight and obese adults (body mass index=34.3±1.2), mean age 61.3±1.1 years, were given an ad libitum standardized breakfast meal on two randomly assigned occasions. Thirty minutes before the meal, subjects were given either a 500-mL water preload or no preload. Energy intake at each meal was covertly measured. Meal energy intake was significantly less in the water preload condition as compared with the no-preload condition (500±32 vs 574±38, respectively; P=0.004), representing an approximate 13% reduction in meal energy intake. The percentage reduction in meal energy intake following the water preload was not related to sex, age, body mass index, or habitual daily water consumption (all P>0.05). Given the high prevalence of overweight and obesity among older adults, future studies should determine whether premeal water consumption is an effective long-term weight control strategy for older adults.
