Factors Related to Dietary Behaviors in Vietnamese Persons with Recurrent Kidney Stone Post-Operation

Abstract

Urinary stone disease is one of the most common afflictions of modern society accounting for nearly 1 million visits to emergency departments (EDs) in the United States annually, although it has been described since antiquity. Diet behavior is an important factor in this disease because the structures of the stones are normally based on the diet which the patients took. Therefore, the purpose of this study was to examine the dietary behaviors, and to examine the relationships between factors and dietary behaviors among Vietnamese patients with recurrent kidney stone post-operation.  A cross-sectional descriptive correlation design was applied to data collected from 112 participants treated at two urological surgical departments of Viet Duc Hospital and Military Medical no.103 Hospital from October to December 2013. All participants completed five section self-administered questionnaires. Data were analyzes using percentages, means, and standard deviation. Pearson’s correlation coefficient was applied to determine the relationships among the study variables.  The results show that age and body mass index were not significantly correlated with dietary behaviors. However, gender was negatively associated with dietary behaviors (r = -.34; p < .05). There were strong significant relationships between perceived self-efficacy of dietary behaviors, perceived benefits of dietary behaviors, perceived barriers of dietary behaviors and dietary behaviors, in which perceived benefits had the strongest correlation with the dependent variable (r = 0.83; p < .05). Based on the findings of this study, clinical nurses in the Urological Surgical Department should counsel patients about the benefit of dietary changes and prepare a discharge plan to promote healthy dietary behavior before patients return to their community.
