Diabetes mellitus is a disease ,  due  to  the  deficiency in producing , or

   deficiency of insulin function that causes many problems. Insulin dependent 

   diabetes    mellitus  ( IDDM )   patients    need   to    inject    insulin   regularly.

   To  determine  the insulin injection  compliance  a descriptive observational

   study has  been performed on the patients who  had referred to Hamadan

   Diabetic  Research Center , thus  the role of health attitudes  in compliance

   was determined.

         The  studied patients , were 245 persons and they had been covered by

   above center . Questionnaire was used in this study .                                                                 

         Finding  indicated that 62.05% of   them    had   less  than  40  years   old

   and most of them were female(68.16%). About 73.46% patients had disease

   less than 10 years . The majority of them (60.6%) did not  have  IDDM  in their

   family. They had taken part in training courses held in this  center  and  they

   had perceived the advantages of insulin injection.62.4% of them had good

   compliance  about  insulin  injection . The  most  important  barrier  in  insulin

   injection was the high price of this  drug  and also to provide it. The patients

   with IDDM that  perceived  the  seriousness of  disease  and  susceptibility to

   having any complication, these two factors  had a meaningful relation with

   insulin  injection  compliance. Insulin  injection  compliance  had  significant

   relation   to   age  ,  education   and    marriage . The   other   demographic

   characteristics  did   not  demonstrate  the  meaningful  relation  with insulin

   injection compliance .                                                                                          

         Most of the people had  good  compliance  about insulin   injection. This

   indicates the role  of Diabetes  Research Center  can be useful because this

   center  educates  the  patients about the diabetes complications, and can

   help the patients to comply fully with insulin injection.
