Intensive low-glycaemic-load dietary intervention for the management of glycaemia and serum lipids among women with gestational diabetes: a randomized control trial.
OBJECTIVE The present study aim ed to compare the effects of a general dietary intervention and an intervention with low glycaemic load ( GL ) on glycaemic control , blood lipid metabolism and pregnancy outcomes in women with gestational diabetes mellitus . DESIGN Participants were r and omly assigned to two groups , receiving either an individualized general dietary intervention ( Control group ) or an intensive low-GL intervention ( Low-GL group ) every two weeks , from 24 - 26 weeks of gestation to delivery . SETTING The Center of Maternal Primary Care in Guangdong General Hospital , China . SUBJECTS Ninety-five women with gestational diabetes mellitus were enrolled from June 2008 to July 2009 . RESULTS After the intervention , both groups significantly decreased their dietary intakes of energy , fat and carbohydrate . The Low-GL group had significantly lower values for GL ( 122 v. 136 ) and glycaemic index ( 50 v. 54 ) but greater dietary fibre intake ( 33 v. 29 g/d ) than did the Control group ( all P<0·01 ) . Significantly greater decreases in fasting plasma glucose ( -0·33 v. -0·02 mmol/l , P<0·01 ) and 2 h postpr and ial glucose ( -2·98 v. -2·51 mmol/l , P<0·01 ) , significantly lower increases in total cholesterol ( 0·12 v. 0·23 mmol/l ) and TAG ( 0·41 v. 0·56 mmol/l ) and a significantly lower decrease in HDL cholesterol ( -0·01 v. -0·11 mmol/l ) were also observed in the Low-GL group compared with the Control group ( all P<0·05 ) . There were no significant differences in body weight gain , birth weight or other maternal-fetal perinatal outcomes between the two groups . CONCLUSIONS The low-GL targeted dietary intervention outperformed the general dietary intervention in glycaemic control and the improvement of blood lipid levels in women with gestational diabetes mellitus
