[Effects of lifestyle and quantitative nutrition interventions on individuals with prediabetes].

Abstract

OBJECTIVE:

To explore the impact of lifestyle and quantitative nutrition intervention on individuals with prediabetes.

METHODS:

A total of 214 prediabetic patients from epidemiologic survey in Ximazhuang and Guangrunmen community centers in Nanchang from January 2011 to January 2012 were enrolled in the study. All the participants were randomly divided into two groups: the intervention group and the control group, with 107 patients in each group. Intensified lifestyle and quantitative nutrition interventions were carried out in the intervention group, and routine lifestyle intervention was carried out in control group. Height and weight were measured, and the body mass index (BMI) was calculated. Blood glucose was tested by glucose oxidase method, and glycosylated hemoglobin (HbA1c) was detected by high performance liquid chromatography. Various parameter changes were compared between two groups after two year's follow-up, and the outcome data of patients was collected. The study was approved by the Ethics Committee of the Third Hospital of Nanchang.

RESULTS:

There were no significant differences in each parameter between two groups before intervention (all P>0.05). No obvious change was found for the parameters in the control group after two year's follow-up (all P>0.05), but weight, BMI, fasting blood glucose, postprandial two-hour blood glucose and HbA1c decreased in the intervention group (P<0.05). There were 11 (13.1%) diabetic cases and 1 (1.2%) participant with normal glucose tolerance in the control group, and 3 (3.4%) diabetic cases and 7 (8.0%) participants with normal glucose tolerance in the intervention group (P<0.05). The risk of diabetes in two groups was performed using cox regression model analysis, and the primary end-point was the incidence of diabetes. The risk of diabetes in the control group was significantly higher than that in the intervention group [HR=3.903, 95% CI: 1.089-13.992, P=0.037].

CONCLUSION:

The lifestyle and quantitative nutrition interventions may improve the blood glucose control and delay the progression of diabetes in prediabetes patients.
