Soy drink replacement in the diet might have beneficial effects on anthropometric and blood pressure values for overweight and obese subjects. Therefore, we are going to determine the effects of soy drink replacements on the weight, waist circumference and blood pressure among overweight and obese female youths.
This was a cross-over randomized clinical trial on 23 overweight and obese female subjects. All patients were on a weight reducing diet. There were two trial periods for six weeks (soy drink period and cow's milk period) and a washout period for 3 weeks. In the soy drink period only one glass of soy drink (240 cc) was consumed instead of one glass of cow's milk.
The mean age of the patients was 22±2 years. Mean of BMI was 28.1±0.5. Weight and waist circumference did not changed significantly after the soy drink period compared to the cow's milk period. Systolic blood pressure reduced significantly following the soy drink period (mean percent change in soy drink period: -4.0±0.9 vs -1.7±0.5 in the cow's milk period; p<0.05). Diastolic blood pressure also reduced in the soy drink period (-0.4±0.1 vs 0.4±0.1; p<0.05).
Soy drink replacement could reduce both systolic and diastolic blood pressure among overweight and obese female youths. However, this replacement had no significant results on weight and waist circumference.
饮食中用豆奶替代可能对超重和肥胖受试者的人体测量指标及血压值产生有益影响。因此，我们将确定豆奶替代对超重和肥胖女性青少年体重、腰围及血压的影响。
这是一项针对23名超重和肥胖女性受试者的交叉随机临床试验。所有患者均采用减重饮食。有两个为期六周的试验期（豆奶期和牛奶期）以及一个为期三周的洗脱期。在豆奶期，仅饮用一杯豆奶（240毫升）以替代一杯牛奶。
患者的平均年龄为22±2岁。体重指数均值为28.1±0.5。与牛奶期相比，豆奶期后体重和腰围无显著变化。豆奶期后收缩压显著降低（豆奶期平均变化百分比：-4.0±0.9，而牛奶期为-1.7±0.5；p<0.05）。豆奶期舒张压也降低了（-0.4±0.1对0.4±0.1；p<0.05）。
豆奶替代可降低超重和肥胖女性青少年的收缩压和舒张压。然而，这种替代对体重和腰围没有显著影响。
