Brazil currently lives in a new scenario of serious nutritional problems in childhood. In addition to malnutrition in several regions of the country, another nutritional disorder is raised: excessive weight. In addition to this context, in 2020, COVID-19 appears, making this scenario even more problematic. Thus, this study aimed to evaluate the effects of the pandemic on the nutritional health of children aged 0 to 10 years, in relation to their overweight, in the national territory. A cross-sectional, retrospective and quantitative approach was developed. Data for research were taken from official government websites, namely: SISVAN - Web (Food and Nutrition Surveillance), DATASUS and e-SUS Web, in which sociodemographic data from Brazil were analyzed and in its five socio-political regions. The variables analyzed were: gender, age group and zone of occurrence. The profile showed no statistically significant differences in the prevalence of children’s overweight in Brazil, regardless of age group, in the period between 2017 and 2021. However, there was a clear trend, although not significant, of increased prevalence of children with overweight, except in the age groups from 0 to 6 months and from 6 months to two years, which showed a stationary trend. In relation to the socio-political regions, it was possible to identify a trend of increasing weight gain for age, in all regions, being lower in the North and higher to the Southeast region. It should be noted that this trend of increasing weight gain was only significant in the southern region, where the prevalence of overweight was significantly higher (G Test; p<0.0001) in 2021. There is no statistically significant difference between gender groups, despite the greater number of cases being male. Thus, it can be concluded that child weight gain is closely related to multifactorial causes, among which we can highlight the socioeconomic region, culture, social isolation in the pandemic and purchasing power. In this way, the importance of the nutritionist professional in the health units is reinforced, as the main propagator of actions aimed to promote, treat and rehabilitate children's health, especially through the pandemic.

This study aimed to describe the epidemiological profile of food poisoning in Brazil with its trends and prospects for prevention, between the years 2016 and 2020. A cross-sectional, retrospective study with a quantitative approach was developed, the data for the research were taken from official government websites, namely: SINITOX (National System of Toxic-Pharmacological Information), DATASUS and IBGE (Brazilian Institute of Geography and Statistics). It became evident that a significant and sharp decrease in cases of food poisoning in Brazil and in its five socio-political regions (p<0.0001) in the year 2020, such fact being probably related to the advent of the COVID-19 pandemic. Regarding the occurrence of food poisoning by gender there was predominance in males with a sharp and significant decrease in the year 2020 for both genders. The age group between 15-19 years was the most prevalent, followed by children under 1 year old. Thus, it can be concluded that food poisoning is closely related to food consumption outside the home, reinforcing the importance of the professional nutritionist as a propagator of good hygiene, handling, and healthy eating practices.
