Abstract:
Objective:To study the effect of nutrition intervention on the body composition and blood glucose in newly diagnosed patients with type 2 diabetes mellitus complicated with overweight and obesity.
Methods:A total of 84 newly diagnosed patients with type 2 diabetes mellitus complicated with overweight and obesity were selected from the department of endocrinology in China-Japan Friendship Hospital from April 2015 to December 2016. Basic information and body composition of these patients were collected and measured. Also the food frequency questionnaire (FFQ) was used to investigate the dietary status in the past month, and calculate the intake of energy, three major nutrients and dietary fiber. All patients received nutrition intervention by nutritionist for three months as requested by Diabetes guidelines. After 3-month intervention, blood glucose, body composition and dietary status were examined again. Relevant indicators of patients were compared before and after the intervention. All patients were divided into three groups according to the degree of body mass index (BMI)′s change: <5%, 5%-10% and >10%. The differences of body weight, muscle, body fat rate, visceral fat index and blood glucose level among three groups were quantified.
Results:There were 53 male patients with age (41.5±8.9) years and HbA1c (7.5±0.4)%, and 31 female patients with age (40.1±8.5) years with HbA1c (7.6±0.5)%. The intake of energy, carbohydrate and fat of patients were significantly decreased (P<0.05) and dietary fiber was significantly increased (P<0.05) after nutrition intervention. The body weight, muscle mass, fat mass and visceral fat index were also significantly decreased (P<0.05). The average decrease of fat was about 2.8 kg accounting for 73.7% (2.8 kg/3.8 kg) of the total weight loss. The body fat rate decreased from (31.2±3.1)% to (28.8±3.2)% (P<0.05). The fasting blood glucose and postprandial blood glucose were both decreased significantly after intervention (P<0.05). Among three BMI decreased groups, there was no significant difference in body weight and muscle mass (P>0.05), but a significant difference in body fat rate and visceral fat index (P<0.05). The body fat rate, visceral fat index, fasting blood glucose and postprandial blood glucose had more decreases with the greater amount of weight loss (P<0.05).
Conclusion:The three-month nutrition intervention could change the dietary habit and components of patients with type 2 diabetes mellitus by reducing the blood glucose, body fat rate and visceral fat index significantly. The degree of reduced BMI is positively related to the decrease of fasting blood glucose and postprandial blood glucose.
