AB  - Adolescence  comprises  a  period  in  the  life  cycle  between  childhood  and  adulthood.  Biological,  psychological,  social,  environmental,  and  legal  changes  influence  the  definitive  onset  and  termination  of  adolescence.  Pubescence  is  often  described  as  the  onset  of  adolescence;  however,  the  mean  age  of  onset  of  puberty  in  girls  in  the  United  States  varies  by  race  and  is  earlier  than  in  previous  generations.  The  mean  age  of  onset  for  white  girls  is  9.7  years  with  a  range  of  onset  from  7.8  to  11.6  years;  and  for  black  girls,  8.1  years  with  a  range  of  onset  from  6.1  to  10.1  years.  In  boys,  the  onset  of  puberty  has  remained  stable  at  11.4  years  of  age  with  a  range  of  9.5  to  13.51-6  (see  Chapter  540).  For  purposes  of  discussion  in  this  section,  adolescence  in  chronologic  years  is  defined  as  the  period  from  10  to  21  years.
