Study of effective antiobesity project in diet and physicalexercise for patients with simple obesity

目的探讨单纯性肥胖者有效减肥的饮食和运动方案。方法选择体重指数(BMI)>25的30例为研究对象,采用自行设计的问卷形式通过对膳食史、饮食习惯和体力活动等进行回顾性调查,再进一步通过对研究对象进行3个月的饮食和运动减肥方案的实验,对观察指标进行统计学处理。结果研究组既往每日膳食总热能、脂肪供热比显著高于推荐的每日膳食中营养素供给量(recommendeddietaryallowance,RDA)。喜甜食及与经常进食过饱者的百分比分别为64%、62%,对研究组进行3个月的饮食和运动方案的实施实验,研究组实验后每日膳食总热能、脂肪供热比、蛋白质供热比、BMI、腰围、臀围、上臂围显著低于实验前。结论高热能、高脂肪、缺乏钙的膳食,喜饱餐和喜甜食及缺乏体力活动是诱发肥胖的重要影响因素。我们提出的饮食和运动方案减肥有效。

Objective To study the effective antiobesity project in diet and physical exercise for patients with simple obesity. Methods 30 volunteers with body-mass index （BMI） 〉 25 were investigated by questionnaire. The analysis was focused on such factors as dietary history, diet habits and physical activities. They were enrolled and received diet and physical exercise program for 3 months. Their BMI were measured before and after test respectively. The results were analyzed using statistical method. Results The total intake of energy and fat per day in obesity group in the past was significantly higher than that of the recommended dietary allowance. The percentage of always eating too much and favoring sweetmeat in obesity group was 64% and 62 %. While less physical activities were found in obesity group. It showed that the total intake of energy, fat and protein per day in obesity group before test was significantly higher than that after test （ P 〈 0.05）. BMI,The waistline, the hip, the line of upper arm were significantly higher before than after test （ P 〈 0.05） in the study group. Conclusions The results suggested that diet rich in high energy and fat, bad diet habits of always eating too much and favoring sweetmeat, less physical activities were the important factors of triggering obesity.
