ADESÃO ÀS ORIENTAÇÕES NUTRICIONAIS: UMA REVISÃO DE LITERATURA

Patient compliance with nutritional guidelines is essential to achieve the results expected from nutritional education. The phenomenon of adherence and non-adherence brings great impact on morbidity and mortality in individuals affected by chronic diseases and it is one of the major problems faced by health professionals. The aims of this study were to identify how adherence to nutritional guidance and its determinants are assessed and to summarize ways to improve adherence. A literature review has been made in the electronic databases SciELO, LILACS, PubMed and ClinicalKey from 2005 to 2015. Throughout the literary review, it was found that adherence assessment can be subjective or objective and that adherence has been evaluated with different types of instruments because of the great difficulty posed by the measurement of this variable. Multiple interfaces influence adherence to treatment, e.g., patient, disease, therapy, socioeconomic and cultural aspects, health system and relationship with healthcare professionals. Because the dimension of the topic of adherence is complex, there is no method or instrument that fits all the objectives and studies. However, methodological studies are needed to develop and validate instruments to assess adherence to nutritional orientations. DOI: 10.12957/demetra.2017.22407
