Comparative study between two feeding schemes for glycaemic control in children with type 1 diabetes mellitus
ISRCTN ISRCTN39293069
ClinicalTrials.gov identifier
Public title Comparative study between two feeding schemes for glycaemic control in children with type 1 diabetes mellitus
Scientific title Comparative study of the effectiveness of two schemes dietetic glycaemic index of foods with high versus low postprandial glycaemic control in children with type 1 diabetes mellitus: a controlled cross-over clinical trial
Acronym LGI, HGI
Serial number at source 72/2008
Study hypothesis A dietetic scheme with a low glycaemic index (less than 55) will be more effective in maintaining the concentration of postprandial serum glucose (less than 180 mg/dl) than a dietetic scheme with a high glycaemic index in paediatric patients with diabetes mellitus type 1 (DM 1).
Ethics approval Ethics Committee of the National Institute of Pediatrics approved on the 2nd October 2008 (ref: 72/2008)
Study design Crossover randomised controlled trial
Countries of recruitment Mexico
Disease/condition/study domain Type 1 diabetes mellitus
Participants - inclusion criteria 1. DM1 patients between 10 to 18 years of age monitored by the Department of Endocrinology, National Institute of Paediatrics
2. Patients of either sex
3. Patients with controlled DM1:
3.1. Concentration of fasting serum glucose 95 - 130 mg/dl
3.2. Glycosylated haemoglobin less than 7.5%
5. Signing of informed consent and settlement
6. Eight hours of fasting
7. Treated with intermediate and/or rapid long-acting insulin for more than 6 months
Participants - exclusion criteria 1. Patients with infectious processes at least 72 hours of admission to the protocol
