Background: The study of body composition in patient candidates for bariatric surgery is directly related to the increase and distribution of body fat in the development of cardiovascular disease. Aim: To correlate anthropometric indicators and bioelectrical impedance in the assessment of body fat in female candidates for bariatric surgery. Methods: Cross-sectional, observational study of 88 women. The weight, height, body mass index and waist circumference data were evaluated in the anthropometric analysis. The body fat was determinate by bioelectrical impedance conducted according to the manufacturer´s recommended technique with a specific severe obesity formula. The patients were divided into two subgroups according to the average waist circumference and body mass index for better analysis of the results. Results:The group had a mean age of 39.7 years (±7.2), average weight of 125.6 kg (±16.2), mean body mass index of 48.7 kg/m2 (±6.4) and the mean waist circumference 137.6 cm (±12.4). Negative and significant relationship between BMI values waist circumference and resistance obtained by bioelectrical impedance ​​were found. By analyzing the two groups the mean BMI and waist circumference, a significant relationship was observed, ie, the higher the degree of obesity less resistance was obtained by bioelectrical impedance. The higher is the obesity the lower is value found for resistance. Conclusion: The increase of anthropometric indicators (BMI and waist circumference) determined reduction in resistance and reactance obtained by bioelectrical impedance analysis in obese women candidates to bariatric surgery.

Objective: Evaluate the impact of the covid-19 pandemic on weight regain in post-bariatric women and correlate it with symptoms of anxiety, depression, binge eating, and fear of covid-19. Methods: It collected anthropometric and mental health information with the application of psychometric scales on the patients mentioned above, between May/2021 and January/2022. Frequencies (descriptive statistics), test t for independent samples, and Spearman were used to obtain a correlation between weight gain and the psychometric scales. Results: The sample comprised 25 women. The average age was 53.0 years and the average body mass index was 35.2kg/m2 before the pandemic. We observed an average increase in the body mass index of 1.4 points during the pandemic. However, 40% maintained or lost weight during the same period. The weight gain group had higher scores for depression, anxiety, and binge eating symptoms. Fear of covid-19 scores did not differ between the groups. Conclusion: Anxiety, depression, and binge eating symptoms have influenced weight to regain in a small sample of post-bariatric women during the covid-19 pandemic.
