Other related concerns are diabetes and high blood pressure.  These two conditions often accompany obesity.  It's too soon to know if these are causes or just association but with rates skyrocketing to 1 in 88 nationally and  even higher locally at 1 in 47 (See SLTrib article here) we need to find answers. Boys are affected more frequently than girls (1 in 32 in Utah - see SLTrib article here).
