“…(2010) demonstrated a positive relation between exposure to brand positioning and the behavior of choosing it [22]. The preference for branded articles has been associated with the higher number of TV sets in the home, which suggests that exposure to TV commercials influences children's preferences [1,23].…”

(1) Background: Childhood obesity is a public health problem. The purpose of this study was to know if exposure to commercial messages which advertise food products exerts any effect on the short-term consumption preferences of 4- to 6-year-old children. (2) Methods: A double-blind and randomized experimental design. Sample consisted of 421 boys and girls from twelve schools in a city in Spain. (3) Results: In three of the four product pairs shown, the products advertised in the intervention were preferred. In the results of applying the model for the first product pair presented, sugared cereals, the predictive variable which best explains the behavior of the preferences expressed is gender (Odds Ratio 0.285 (0.19–0.42); p < 0.05). For the second pair, chocolate cookies, the family’s nationality has a strong weight in the model. As regards the regression model calculated for the last pair (filled rolls), the predictive variable which showed having more influence was gender. Boys had a 1.39 times higher risk of selecting the advertised product than girls. (4) Conclusions: The persuasive effect of commercials has shown to be influential in a general, immediate, and significant way only in the case of products with wide brand awareness. This study reinforces the importance of advertising and emphasizes the need to initiate measures to control the content of TV commercials.

The aim of this study is to describe the prevalence of sports participation in Brazilian children and adolescents through a systematic literature review. A search was carried out in the following electronic databases: MEDLINE, WEB OF SCIENCE, BIREME, SCIELO, and SCOPUS for manuscripts published until 2020, combining the keywords: “children”, “adolescents”, “prevalence”, and “sports participation”, in Portuguese and English. Twenty-six articles published between 2003 and 2020 were included in the review, with the aim of estimating the prevalence of participation in organized sports in Brazilian children and adolescents. Considering the regions where the studies were carried out, the majority were developed in the south (57.7%; n=15), followed by the southeast (19.2%; n=05), and northeast (15.4%; n=04), in addition to 7.7% (n=02) in all regions of the country. The data showed prevalence of sports participation ranging from 15.0% to 73.2% (mean of 44.8%) among children and adolescents, being higher in males (63.1%). From the results found, the need to develop public policies is evident, in order to favor adherence and maintenance of young people to sports practice, especially among those of the female sex.

Aim: To investigate the causal impact of diet and sedentary behavior on Brazilian schoolchildren’s overweight/obesity using the data from observational studies. Methods: Annual cross-sectional nutritional surveys over the 2013–2015 period, with 26,712 children old 7–12 years in Florianópolis, Brazil, provided the data for this analysis. The surveys applied an online previous-day recall questionnaire on food intake and physical/sedentary activities. Outcome measures were overweight/obesity, whereas exposure variables were daily frequencies of consuming sugary drinks and ultra-processed foods, the total number of dietary items consumed and the total number of sedentary activities per day, and consuming breakfast, mid-morning snacks, lunch, afternoon snack, dinner, and evening snack. Control variables included child age, sex, family income, school shift, survey year, day of the week the questionnaire refers to, metabolic equivalents (METs) of physical activities (PAs), and the quality of dietary and PA reports. Causal effects were estimated by augmented inverse probability weighting. Results: Daily consumption of sugary drinks, eating ten or more foods, and engaging in three or more sedentary behaviors per day significantly increased the odds ratios (ORs) of being overweight/obese in the range of 3–24% compared to the reference, with 95% confidence intervals in the range of 1–32%. Among 19 ORs with P-value ≤ 0.05, only 3 exceeded 10%. Conclusions: Under certain conditions, not uncommon in large-scale monitoring and surveillance studies, it is possible to evaluate the causal effects of diet and sedentary activities on overweight/obesity. Daily consumption of sugar-sweetened beverages, eating ten or more foods, skipping breakfast, and engaging in three or more sedentary behaviors per day significantly increased the odds of being overweight/obese.
