This study's objective is to review the consequence of the COVID-19 epidemic on physical activities, sedentary lifestyles, screen time, and changes in the nutritional status of school-age children. The outcomes of this study are intended to be applicable to obesity management in children. This study reviewed full-text articles and open-access publications on the sedentary lifestyle of children during the pandemic. and the data were analyzed using cohort, case-control, and cross-sectional designs. The results of reviewing 17 articles show that school-age children's physical activities and nutritional status have decreased, but their sedentary lifestyle and screen time have increased due to social restrictions during the COVID-19 pandemic. Children's decreased physical activities are caused by the absence of a comparable replacement mechanism as that before the pandemic. Meanwhile, the increasingly sedentary lifestyle highly influences children's physical and mental health. Screen time has also increased and is unavoidable during the pandemic because children's activities were limited and their learning systems are switched to online learning; as a result, their supporting sedentary lifestyle increases while physical activities decrease. These factors have changed the nutritional status of children during the pandemic. These results support the idea that the pandemic will impact the health of school-age children, especially their nutritional status. This review concludes that it is important to establish policies that prevent children's further health effects, such as obesity, caused by COVID-19.

Background: The deficiency of energy, protein, and other beneficial nutrients during pregnancy causes chronic energy deficiency (CED). This condition increases the chance of having babies with low birth weight (LBW) and various other health problems. To meet these nutritional needs, supplementary feeding is necessary in the form of snack bar, using local food ingredients, such as purple sweet potatoes and soybeans (PSPS). This study determines the differences in a few aspects of PSPS snack bar, such as sensory acceptability, physical quality, and nutritional content in several formulations.Design and Methods: The best three formulations were selected through sensory acceptability by involving 40 panelists and showed the following results P0 (commercial product), P2 (80% purple sweet potato: 20% soybean), and P3 (70% purple sweet potato: 30% soybean). Furthermore, these formulations were triplicated for further physical color test, the hardness and breaking force, as well as the nutritional analysis that includes both macro and micronutrients.Results: The results showed significant differences (p<0.05) in the sensory acceptability, physical quality, nutritional content (except carbohydrate and iron), and antioxidant activity.Conclusions: In conclusion, snack bars with 70% purple sweet potato and 30% soybean gave the best formulation.
