LEIJA ALVA, Gerardo et al. Cognitive factors predicting therapeutic adherence in people with overweight and obesity. Rev. Mex. de trastor. aliment [online]. 2019, vol.10, n.1, pp.85-94. ISSN 2007-1523.

The lack of adherence to treatment (ADT) in people with chronic diseases range from 40 to 75%. Two thirds of the patients with obesity under treatment recover the weight lost after one year, and almost all of them after five years, which is associated with the lack of ADT. Adherence refers to a multidimensional phenomenon that involves the reciprocal action of several factors, including those related to the patient. Assumption that triggered the first socio-cognitive models of ADT. The aim of the present work was to identify which factors of three different models (Theory of the planned behavior [TPB], Beliefs in health, and the one of Wallston) can predict the ADT of patients with overweight or obesity. A total of 118 adults participated, with an average age of 52.0 years (SD = 19.0), who were under pharmacological treatment and completed three questionnaires, each one related to the models evaluated, and another one related to ADT. Of the 13 factors, only one (attitudes, from the TPB model) showed ability to predict ADT (t = 2.75, ß = .26, p < .01). Therefore, for overweight and obesity it is necessary to propose models that can reflect better the differences that underlie the ADT.
