A Trial of Simple versus Intensified Dietary Modification for Prevention of Progression to Diabetes Mellitus in Women with Impaired Glucose Tolerance
Summary : Women with impaired glucose tolerance are at high risk of developing noninsulin dependent diabetes mellitus ( NIDDM ) . The Mercy Hospital for Women has a long‐term follow‐up programme for women with gestational diabetes , which identifies many women with impaired glucose tolerance . Two hundred of these women were entered into a r and omized controlled trial of intensive versus routine dietary advice . Seven women were lost to follow‐up . The annual incidence rates of diabetes mellitus for the 2 groups were 6.1 % ( intervention ) and 7.3 % ( control ) , an incident rate ratio of 0.83 , 95 % confidence interval 0.47–1.48 , p = 0.50 . Overall , there was a return to normal glucose tolerance in 44 % of patients . Multivariate analysis showed that body mass index , fasting and 2‐hour plasma glucose levels at trial entry were significantly associated with an increased risk of diabetes mellitus . Impaired glucose tolerance is an important condition that should be treated with advice about lifestyle modification ( diet and /or exercise ) . We consider that future trials in the management of women with previous gestational diabetes who have impaired glucose tolerance should investigate the effect of pharmacological intervention in addition to diet and /or exercise , the latter providing a therapy that it would be unethical to exclude on the evidence presently available
