Background: In this study, the association between psychosocial factors and exercise engagement was investigated among adult users of the primary healthcare level. The prevalence of chronic diseases such as overweight/obesity, hypertension, and type 2 diabetes is high in the Mexican adult population. Adherence to healthy lifestyles like regular exercise is part of the prevention and treatment of these diseases, which is why its promotion should be encouraged from the primary healthcare level. To achieve this, it is necessary to understand the factors associated with exercise engagement in this population.
Methods:A cross-sectional study was conducted. The dependent variable was adherence to exercise recommendations for the adult population? The Global Physical Activity Questionnaire was used, and the metabolic equivalents per week expended on exercise were calculated. The psychosocial variables included were stages of readiness for change, self-efficacy, decisional balance, and outcome expectations regarding exercise. Sociodemographic and health factors were also included. Ordered logistic regression was employed in the statistical analyses.Results: 406 adults participated. The multivariate analysis revealed associations between stages of readiness for change and selfefficacy with the categories of exercise adherence. For each point increase in the self-efficacy scale, the likelihood of being in the category meeting the exercise recommendation would increase by 1.8%, while the likelihood of being in the category of not engaging in exercise would decrease. Males versus females, and adults aged 20 to 31 years versus adults aged 32 to 64 years, had higher possibilities of being in the category meeting the exercise recommendation.Conclusions: Psychosocial factors such as stages of readiness for change and self-efficacy, as well as sex and age, should be considered in developing exercise promotion strategies for Mexican adults utilizing primary healthcare services.
