FARIAS-VILCHEZ, Bruno Alessander  and  RUIZ, Darío Bardales. Knowledge on diabetes mellitus type 2 and adherence to treatment in patients from the hospital Reátegui from Piura, Peru. Acta méd. Peru [online]. 2021, vol.38, n.1, pp.34-41.  Epub May 23, 2021. ISSN 1728-5917.


To determine the association between knowledge about Diabetes Mellitus, Type 2 (DM2) and adherence to treatment in patients of the Jorge Reátegui Hospital, Piura, Peru.


Study carried out in 236 patients from the Jorge Reátegui Hospital, Piura, Peru, who attended the endocrinology office during 2019. Adherence and level of knowledge were evaluated through questionnaires: Morisky Green-8 test (high, medium or low adherence) and Test Diabetes Knowledge Questionnaire 24 (adequate and inadequate). Multinomial logistic regression was applied between the variables, in SPSS v.25.


Inadequate knowledge predominated (68.2%); over the adequate (31.8%). Adherence was low (38.6%); medium (31.4%) and high (30.0%). An association was found between knowledge and adherence to treatment (p<0,05). Also, between educational level (p<0,05) and origin (p<0,05). If the patient does not present studies, it is associated with low adherence OR 6,24 (CI (2,11 -18,44)), or mean OR 3,72 (CI (1,20 -11,49)). In addition, if the patient presents primary, it is associated with low adherence OR 5,59 (CI (1,76 -17,70)). Likewise, if the patient comes from a rural area OR 5,92 (IC (1,59 -21,97)), or marginal urban OR 4,43 (IC (1,27 -15,41)) associated with low adherence. An association was found between inadequate knowledge and low adherence OR 3,45 (CI (1,74 -6,81)), or mean OR 2,62 (CI (1,31 -5,24)).


There is an association between knowledge about diabetes and adherence; inadequate knowledge predisposes to a higher risk of low or medium adherence. Likewise, certain sociodemographic factors such as the degree of education and the origin.
