Abstract

The  purpose  of  this  study  was  to  investigate  the  causal  relationships  model  of  the  factors  influencing glycemic  control  among  the  elderly  with  type  2  diabetes  mellitus  (T2DM).  A  multi  stage  sampling  was used  to  recruit  390  patients  with  type  2  diabetes  from  9  primary  care  units  in  Sukhothai  Province.  Data were  collected  by  questionnaire  with  reliability  value  of  knowledge,  social  support  and  self-care  behaviors were  0.81,  0.82  and  0.82,  respectively.  Data  were  analyzed  using  descriptive  statistics  and  testing  a  causal relationship  model  by  path  analysis.


The  results  showed  that  58.5%  were  females.  Of  57.7%  had  duration  of  illness  1-  5  years  with  the mean of 5.48 years and S.D. of 2.42. Most of them (59.5%) aged 60-64 years with the mean age of 63.98 years  and  S.D.  of  =  2.29.  Half  of  the  sample  had  poorly  controlled  fasting  blood  glucose  (FBG  ≥  126 mg/dl)  with  the  mean  of  135.19  mg/dl.  The  analysis  of  a  causal  relationship model  illustrated  by  social support  demonstrated  direct  effect  on  self-  care  behaviors  (β =  0.81,  p-value <  0.05),  and  explained  the variance  in  self  –  care  behaviors  at  91%.  On  the  other  hand,  diabetes  knowledge  had  no  direct  effect  on self-care  behaviors  (β =  0.15, p-value <  0.05).  However,  self-care  behaviors  had  a  negative  direct  effect on  FBG (β =  0.82, p-value <  0.05),  and  explained  the  variance  in  FBG at  67%.


In  conclusion,  social  support  was  the  most  important  factor  on  diabetes  self-management. Meanwhile, the knowledge cannot change their behavior. In order to control T2DM among the elderly, the focus should  be  on  promoting  social  support  rather than  diabetes  knowledge.
