Objective To systematically review the literature on the prevalence and the factors associated with physical activity level and nutritional status of Brazilian children. Methods The electronic database MEDLINE (via PubMed), SciELO, SCOPUS and Web of Science were selected. The search strategy included the descriptors proposed in the Medical Subject Headings (MeSH): "Motor Activity", "Activities", "Nutritional Status", "Overweight", "Obesity", "Body Mass Index", "Child", "Brazil". Results The search allowed the identification of 141 articles, of which 16 studies were considered potentially relevant and were included in the review. Conclusions Studies about nutritional status and physical activity levels in Brazilian children are still scarce, but the work on this has increased in recent years, especially those that use cross designs, as well as questionnaires to measure physical activity; BMI for nutritional status is still widely used. Furthermore, studies that analyzed the amount of hours designated to sedentary behaviors such as watching TV, playing video-games and using the computer, found that these activities took more than two hours every day.
