Objective: The purpose of this study was to evaluate diet underreporting of women treated for schizophrenia undergoing dietary treatment and to compare it with nonpsychiatric women.
Methods: The study included 23 women (13 with schizophrenia) who had actively sought treatment for weight loss. All subjects were smokers with low activity level. A 24-hour diet recall using standardized food models was used to collect energy intake (EI) reporting . In order to identify participants who reported low EI, we used the Goldberg cut-off methodology.
Results: The percentage of underreporters was higher in patients with schizophrenia [77%, 95% confidence interval (46-95%)] than in controls [50%, 95% confidence interval (19-81%)].
Conclusions: Diet underreporting is a frequent phenomenon in women with schizophrenia requiring dietary intervention.
