Objective: To assess changes in daily habits, food choices and lifestyle of adult Brazilians before and during the COVID-19 pandemic.Design: This observational study was carried out with Brazilian adults through an online questionnaire 5 months after the social distance measures implementation. The McNemar, McNemar–Bowker and Wilcoxon tests were used to investigate differences before and during the COVID pandemic period, adopting the statistical significance of P < 0·05.Setting: Brazil.Participants: Totally, 1368 volunteers aged 18+ years.Results: The volunteers reported a lower frequency of breakfast, morning and lunch snacks (P < 0·05) and a higher frequency of evening snacks and other meal categories during the pandemic period (P < 0·05). The results showed an increase in the consumption of bakery products, instant meals and fast food, while the consumption of vegetables and fruits decreased (P < 0·005). There was a significant increase in the frequency of consumption of alcoholic beverages (P < 0·001), but a reduction in the dose (P < 0·001), increased frequency of smoking (P = 0·007), an increase in sleep and screen time in hours and decrease in physical activity (P < 0·001).Conclusions: It was possible to observe an increase in screen time, hours of sleep, smoking and drinking frequency. On the other hand, there was a reduction in the dose of alcoholic beverages but also in the practice of physical activity. Eating habits also changed, reducing the performance of daytime meals and increasing the performance of nighttime meals. The frequency of consumption of instant meals and fast food has increased, while consumption of fruits and vegetables has decreased.

Background. Overweight is often used as a description after liver transplantation (LTx), but studies on body composition of patients submitted to LTx have only been devoted to early postoperative periods; there is little information regarding abdominal obesity after LTx. The aim of this study was to assess body composition, body mass index (BMI), and waist circumference and verify the prevalence and risk factors for excessive weight, obesity, and abdominal obesity in long-term survivors of LTx. Methods. Post-LTx patients with at least 1 year post-LTx were assessed for their body composition (by bioimpedance), BMI, and waist circumference. Demographic, socioeconomic, lifestyle, and clinical and dietetic variables were collected to assess risk factors using linear and logistic regression analyses. Results. We evaluated 143 patients (51±13 years; 59.4% male; median time since LTx: 4 years). The majority of patients had excessive weight, considering BMI, (58.1%). Considering body composition, 69.9% of patients were overweight and 37.8% obese. Some degree of abdominal obesity was seen in 88% of patients. Independent risk factors for overweight, obesity, and abdominal obesity after LTx included greater BMI before liver disease, weight gain since LTx, family history of overweight, smoking, working, being married, having less time since transplantation, a lower calcium intake, and less sleeping hours. Conclusions. The majority of patients are overweight or obese after LTx, and many of the associated risk factors are modifiable. Thus, patients, especially those who already have identified risk factors for overweight and obesity, undergoing LTx should be encouraged to engage in lifestyle changes early.
