Obesity status is unknown among Hamadan primary-school students.

   The   main  objective  of  this  study  is  to determine its’ prevalence in the

   study population.

         This  study  was  conducted  on   two   thousand   school  children   of

   Hamadan  city, Iran. A  sample of  2000  children  aged 6 - 11  years  was

   surveyed  (1000  boys  and 1000 girls ). The  weight  (kg)  was  taken  by a

   standardized  weighting   scale   while   height   was   measured  using  a

   Plastic-band. For   diagnosis of obesity,  NCHS (National Center for Health

   Statistics) standard method  was  used. The children’s which were among

   the 90 & 95 percentiles were assigned  as obese and those  who were up

   the 95 percentile  were  considered as very obese.

         The results   showed  that 3.5%   percent  of  children were obese and

   2.55%   were  very  obese.  The   prevalence   of   obesity   was  higher   in

   females compared to males(7.2% VS 4% ).The difference  was statistically

   significant (P<0.01).

         The   figures  were compared to those of the United States of America

   and European countries. It can be  concluded that obesity is not a major

   problem in the surveyed population , While , the percent of lean peoples

   (10.2%) in these cases was  higher than the obese  peoples.
