Effect of low-carbohydrate diet combined with intensive diet intervention in adult type 2 diabetes / 公共卫生与预防医学

ABSTRACT

Objective To analyze the effect of 30% low-carbohydrate diet combined with intensive dietary intervention in the treatment of adult type 2 diabetes mellitus (T2DM). Methods A total of 93 adult patients with type 2 diabetes who were treated in Hengshui people's Hospital from February 2019 to September 2021 were selected as the research objects. On the basis of insulin treatment , the patients were randomly divided into two groups , namely the control group (conventional treatment). and observation group (low-carbohydrate diet combined with intensive dietary treatment). After 2 and 6 months of intervention， the differences in blood glucose， pancreatic islets , blood lipids , obesity indexes and adverse reaction rates were analyzed between the two groups. Results A total of 163 patients with type 2 diabetes were included in this study， including 83 in the control group and 80 in the observation group. Before the intervention， the indicators of blood glucose， blood lipids and insulin resistance of the two groups were balanced and comparable. After 2 months of intervention， the related indicators in the two groups were all decreased compared with those before the intervention， and the indicators such as glycosylated hemoglobin（t=9.860，P<0.001)， fasting blood glucose（t=3.552，P=0.005) and two-hour postprandial blood glucose （t=11.441，P<0.001)were observed. The decrease rate in the group was higher than that in the control group； after 6 months of intervention， the triglycerides in the two groups also showed a downward trend， and the observation group [(2.41±0.44) mmol/L] decreased the most（t=7.778，P<0.001). At the same time， after 2 months of intervention， the BMI and waist-hip circumference indexes of the two groups decreased compared with those before the intervention.And， the decrease of observation group hip circumference index [(84.19±8.26) cm] was compared with the control group [(85.92±6.81) cm] was more obvious（t=4.840，P<0.001)； after 6 months of intervention， the BMI（t=2.847，P=0.005) and hip circumference indexes （t=2.399，P=0.018)of both groups decreased significantly， and the decrease was more in the observation group . The correlation results showed that the measurement of fasting blood glucose in adults with type 2 diabetes was positively correlated with hip circumference (r=0.490，P=0.038)， and the two-hour postprandial blood glucose was also positively correlated with BMI (r=0.452，P=0.015) and hip circumference (r=0.396，P=0.020). Conclusion Low-carbohydrate diet combined with intensive dietary intervention can effectively improve blood glucose , blood lipid and insulin levels in adult patients with type 2 diabetes in the same time , which help to control the weight and contribute to the prognosis of patients.
