Welcome  to  Public  Health  moment from  the  University  of  Minnesota. Young  adults  who  are  physically  active  are less  likely  to  develop  high  blood  pressure. That's  according  to  researchers  at the  University  of  Minnesota  School  of  Public  Health. Lead  researcher  David  Jacobs  says  that  the  results  were from  15  years  of  research involving  more  than  4,000  people, starting  with  people  at  age  18  to  30, and  following  their  natural  history. With  a  very  extensive  set  of  measures, the  main  finding  was  that among  those  who  were  more  physically  active, both  at  entry  to  the  study  and  also  throughout  the  study, the  new  occurrence  of  hypertension  was  diminished  by about  15%  Although  this  was the  first  major  study  to  look  at physical  activity  and  hypertension  in  young  adults, the  results  Jacob  says,  are  not  surprising. The  surprising  thing  more  is  the  way our  whole  culture  is  going  to  be  non  physically  active. The  message  is  pretty  strong  that, at  least  in  this  respect  of  hypertension, which  is  not  a  good  thing  to  have, be  more  physically  active  and  maintaining that  activity  is  a  good  thing with  another  public  health  moment.
