Effect of a low glycaemic index diet on blood glucose in women with gestational hyperglycaemia.
AIM The objectives of this pilot study were to determine the feasibility and effect on glycaemic control of a low-glycaemic-index ( GI ) diet in women with gestational diabetes or impaired glucose tolerance of pregnancy . METHODS participants , recruited from the Diabetes-in-Pregnancy Clinic of an inner-city teaching hospital serving a predominantly non-Caucasian population , were r and omized to a low-GI ( n=23 ) or control ( n=24 ) diet and followed from 28 weeks gestation until delivery .  Self-monitored-blood-glucose ( SMBG ) , maternal and infant weight were collected from medical charts .  Dietary intakes were assessed using diet records and question naires . RESULTS diet GI on control ( 58 , 95 % CI : 56,60 ) was significantly higher than on low-GI ( 49 , 95 % CI : 47,51 ; p=0.001 ) . Glycaemic control improved on both diets , but more postpr and ial glucose values were within target on low-GI ( 58.4 % of n=1891 ) than control ( 48.7 % of n=1834 ; p<0.001 ) . SMBG post-breakfast was directly related to pre-pregnancy BMI in the control , but not the low-GI group ( BMI * diet interaction ; p=0.021 ) . Participants accepted the study foods and were willing to consume them post-intervention . CONCLUSIONS a low-GI diet was feasible and acceptable in this sample and facilitated control of postpr and ial glucose . A larger study is needed to determine the effect of a low-GI diet on maternal and infant outcomes
