The individual and population-level health impact of type 2 diabetes is well documented, a fact which recently drove the U.S. Preventive Services Task Force (USPSTF) to ask whether screening among asymptomatic individuals aged younger than 18 years would be worth the effort. The answer is that the task force simply does not know, simply because the agency’s literature search turned up no studies that prospectively evaluated the benefits of screening in this population, signaling a missed opportunity for drug and device makers to intervene in this massively costly disease.
