In a recent publication, Ryan (4) calculated that the number of adverse perinatal events that could be hypothetically preventable with the new criteria would be relatively small and implied that a cost-benefit analysis may not be supportive. He also cogently argued that a raised maternal BMI could in most cases be the major predictive factor for large-for-gestational-age babies and that our approach has become too glucocentric. Using an OR of 2.0 rather than 1.75 for the diagnostic criteria would diagnose the same approximate number of women with gestational …
