“…Undoubtedly, the use of devices during quarantine is an important tool for communication, as they can act as facilitators and can alleviate moments of loneliness. However, in some populations, when in excess, this behaviour negatively interfered in food choices, being associated with worse food choices, including higher consumption of ultra-processed foods (31) and high consumption of snacks, fried foods and sweets (32) . Unfortunately, the increase in screen time has been a reality in other populations during the pandemic, having already been demonstrated in Canadians (33) and Iranians (34) and were related to the increase in sedentary lifestyle.…”

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 five 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: 1,368 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.

“…The diet of the Brazilian population is traditionally characterized by the combination of rice and beans, but in the last years an increase in the consumption of ultra-processed foods has been observed, regardless of the population’s age group [ 35 ]. Of the total calories consumed by Brazilian adolescents, 28% come from ultra-processed foods [ 36 ]. The Food Guide for the Brazilian Population recommends that unprocessed or minimally processed foods be the basis of the diet, and that ultra-processed foods should be avoided in order to promote health [ 37 ].…”

Lifestyle patterns associated with common mental disorders in Brazilian adolescents: Results of the Study of Cardiovascular Risks in Adolescents (ERICA)

2021

View full text Add to dashboard Cite

The association between lifestyle factors and mental health has been evaluated in isolation; however, there has been a lack of information about lifestyle patterns and Common Mental Disorders (CMD) in adolescents. Therefore, the present study aims to assess the association between sets of lifestyle patterns and the occurrence of CMD in Brazilian adolescents evaluated in a national school-based cross-sectional survey. The outcome variable considered was presence of CMD. Lifestyle patterns were identified from the Principal Component Analysis. Consumption of foods, water and alcoholic beverages, sleep, physical activity, and smoking were used to identify patterns as explanatory variables. Sociodemographic characteristics, administrative dependence of the school and, nutritional status, were considered adjustment factors in the regression model. A total of 70,427 adolescents were evaluated. The principal component analysis identified three lifestyle patterns: high consumption of ultra-processed foods and low consumption of unprocessed or minimally processed foods (pattern 1); high consumption of alcoholic beverages and tobacco in the last 30 days (pattern 2); and high consumption of water and high level of physical activity (pattern 3). In the adjusted model, in patterns 1 and 2, the third tertile presented greater chance of CMD (OR 1.68; CI 95% 1.51–1.87 and OR 1.38; CI 95% 1.19–1.60, respectively). In pattern 3, the second (OR 0.88; CI 95% 0.80–0.96) and the third (OR 0.80; CI 95% 0.72–0.88) tertiles presented lower chances of CMD among the adolescents evaluated. Therefore, we suggest that health-promoting practices aimed at adolescents include multiple behaviors, with the objective of ensuring physical, mental, and social well-being.

“…On average, the age of participants was 38.9 years, although half of the studies did not report this information. Fifteen studies focused only on children [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30], seven on adolescents [31][32][33][34][35][36][37], five on pregnant women [38][39][40][41][42], and three on older subjects [43][44][45], whereas others focused on an adult population or on ≥2 target groups. Overall, 58.8% of participants were women.…”

A Systematic Review of Worldwide Consumption of Ultra-Processed Foods: Findings and Criticisms

et al. 2021

A debate is ongoing on the significance and appropriateness of the NOVA classification as a tool for categorizing foods based on their degree of processing. As such, the role of ultra-processed food (UPF) on human health is still not completely understood. With this review, we aimed to investigate the actual level of consumption of UPF across countries and target populations to determine the impact in real contexts. Suitable articles published up to March 2021 were sourced through the PubMed and SCOPUS databases. Overall, 99 studies providing data on the level of UPF consumption expressed as the percentage of total energy intake were identified, for a total of 1,378,454 participants. Most of them were published in Brazil (n = 38) and the United States (n = 15), and the 24 h recall was the most-used tool (n = 63). Analysis of the results revealed that the United States and the United Kingdom were the countries with the highest percent energy intake from UPF (generally >50%), whereas Italy had the lowest levels (about 10%); the latter was inversely associated with adherence to the Mediterranean diet. High variability was also observed based on sex, age, and body mass index, with men, young people, and overweight/obese subjects generally having higher levels of consumption compared to older subjects. Overall, our findings underline the large differences in UPF intake. Since most of the observations derived from studies conducted with food questionnaires are not specifically validated for UPF, further efforts are essential to confirm the results previously obtained and to investigate further the association between UPF consumption and health status, also considering the actual contribution within different dietary patterns, which has been less investigated to date.
