(KSL News) -- Utah has an unusually high number of babies with low birth weight.
A new study published today in the journal Pediatrics, found Utah sees more babies born at potentially unhealthy weights -- of under five-point-five pounds -- more often than the national rate.
The results are puzzling, considering Utah has relatively low numbers when it comes to factors that contribute to tiny babies, such as smoking and drinking.
Last year 6.6 percent of the state's nearly 34-hundred births resulted in low weight births.
