应用膳食平衡指数评价溃疡性结肠炎患者膳食质量及营养状况

Evaluation of diet quality with DBI-07 and nutritional status of patients with ulcerative colitis

目的应用中国膳食平衡指数(DBI-07)对活动期溃疡性结肠炎(Ulcerative Colitis,UC)患者进行膳食质量评价,并分析其与营养指标、活动度等的关系,为UC患者制订科学的营养干预措施提供依据。方法选取我院符合纳入标准的82例UC患者进行研究,用食物频率法对患者进行膳食调查,应用膳食平衡指数DBI-07评分系统进行评价,同时进行人体测量及营养指标测定。数据用SPSS 17.0软件进行处理分析。结果本研究中68.3%的UC患者体质量近半年有不同程度降低,40.2%的患者存低白蛋白血症,34.1%的合并贫血。UC患者TS平均值-20.02±7.97;LBS平均值-22.15±6.78,其中54.9%存在轻度膳食摄入不足、37.8%存在中度摄入不足;DQD平均值24.27±6.21,其中轻、中度失衡分别占80.5%、17.1%。LBS绝对值与体质量减轻程度呈正相关,P<0.05,与血清白蛋白负相关,P<0.01;DQD与白蛋白呈负相关,P<0.01;4 UC患者LBS绝对值与UC活动度呈正相关,P<0.01;DQD值与UC活动度负相关,P<0.01。结论以中国膳食平衡指数DBI-07评价UC患者膳食质量,92.7%的患者存在低、中度摄入不足,97.6%的UC患者存在膳食失衡,均明显高于健康人群。摄入不足是UC患者营养不良的重要原因,应对UC患者进行营养补充或营养支持。

Objective To survey the diet quality of UC patients using Chinese diet balance index(DBI-07)and explore their relationship with nutritional index and activity of disease,thereby to provide evidences of nutritional therapy for UC patients.Methods 82 adult UC patients who met the inclusion criteria were included in our study.They were investigated with food frequency questionnaires(FFQ)and diet quality was assessed with DBI-07.Anthropometric measurement and blood examinations were done.Data were analyzed with SPSS 17 software.Results 68.3%of the UC patients loss their weight during the recent 6 months.40.2%of the patients were found hypoalbuminemia and 34.1%were complicated with anemia.The mean TS,LBS and DQD were-20.02±7.97,-22.15±6.78 and 24.27±6.21 respectively.Percentage of patients in slightly or moderately deficit of food intake were 54.9%and 37.8%.Percentage of the UC patients in slightly or moderately dietary imbalance were 80.5%and 17.1%.The absolute value of LBS and DQD were negatively correlated with serum albumin respectively,and both of them were positively correlated with activity of UC.Conclusion Evaluating the quality of UC with DBI-07,92.7%of UC patients were in slightly or moderately deficit of food intake,97.6%were in slightly or moderately dietary imbalance.These percentages were higher than that of healthy people.It indicated that deficit of food intake is an important reason resulting in malnutrition.Nutrition therapy is essential for UC patients.
