title: [The profile of patients undergoing bariatric surgery in the Brazilian Unified National Health System: a systematic review].
abstract: Nearly one million Brazilians were morbidly obese in 2013. Bariatric surgery is an option for sustained weight loss, and the Brazilian Unified National Health System (SUS) had provided 50,000 such procedures as of 2014. The SUS database does not provide anthropometric and comorbidity data on these patients, so the aim of the current study was to perform a systematic review to assess the profile of SUS patients that underwent bariatric surgery from 1998 to 2014. The MEDLINE, LILACS, SciELO, and Scopus databases were searched, and the methodological quality of the included articles was assessed. Of the 1,591 identified studies, 39 were selected, 95% of which were observational. Patients had a mean age of 41.4 years and mean body mass index of 48.6kg/m2; 21% were males, 61% hypertensive, 22% diabetics, and 31% presented sleep apnea. When compared to international study samples, SUS patients showed similar a anthropometric profile and comorbidities but higher prevalence of hypertension. The studies' low methodological quality suggests caution in interpreting the results.
