目的探索在超重及肥胖人群中应用替餐营养棒对体重相关指标的干预效果,为预防控制超重肥胖提供科学依据。方法选择2014年10月至2015年6月在新疆6家医疗卫生机构就诊且符合入选标准的698例超重或肥胖患者为研究对象,均食用替餐营养棒,进行为期8周的干预,测定干预前后患者腰围、臀围、内脏脂肪、健康评分、基础代谢情况,计算腰臀比和体质指数(BMI)。用SPSS 21.0软件对计量资料进行配对t检验,对计数资料进行χ~2检验。结果与干预前比较,干预后超重、肥胖患者体重、腰围、内脏脂肪、基础代谢和BMI均下降,健康评分上升,差异均有统计学意义(P<0.01);干预前后调查对象的臀围、腰臀比差异均无统计学意义(P>0.05)。超重、肥胖患者干预前后体型分布差异有统计学意义(P<0.01)。其中,健康体重者所占比例由干预前的0%提高至干预后的10.3%,重度肥胖者所占比例由干预前的9.3%下降至干预后的4.6%,差异均有统计学意义(P<0.01)。调查人群干预有效率为49.0%,不同性别、年龄段人群干预效果的差异均无统计学意义(P>0.05),而不同初始体型人群干预效果差异有统计学意义(P<0.01)。结论超重和肥胖人群食用替餐营养棒减肥效果明显,是有效的营养治疗方式。
Objective To explore the intervention effect of nutrition bar for the diet on overweight and obesity in weight-related indicators to provide a scientific basis for the prevention and control of overweight and obesity. Methods A total of 698 overweight or obese patients from 6 medical institutions in Xinjiang from October 2014 to June 2015 were enrolled in this study. All the patients were enrolled in the nutrition bar for 8 weeks. The interventions Waist circumference, hip circumference, visceral fat, health score, basal metabolic status, waist-to-hip ratio, and body mass index (BMI) were calculated before and after treatment. Using SPSS 21.0 software to measure the data paired t test, the count data for the test 2 ~ 2. Results Compared with those before intervention, the body weight, waist circumference, visceral fat, basal metabolism and BMI of overweight and obese patients decreased and the health scores increased after intervention. The differences were statistically significant (P <0.01) Waist-hip ratio differences were not statistically significant (P> 0.05). The body size distribution of overweight and obesity patients before and after intervention had statistical significance (P <0.01). Among them, the proportion of healthy weight increased from 0% before intervention to 10.3% after intervention, the proportion of severe obesity decreased from 9.3% before intervention to 4.6% after intervention, the difference was statistically significant (P <0.01). The effective rate of intervention was 49.0%. There was no significant difference in intervention effect among different sexes and age groups (P> 0.05), but there was significant difference in intervention effect between different initial population types (P <0.01). Conclusion Overweight and obese people eat diet bar nutrition slimming effect is obvious, is an effective nutritional treatment.
