COVID-19 has led several countries to enforce social distancing in order to reduce the rate of transmission, commonly called ‘lockdown’. These lockdowns have impacted people’s work, education, travel and recreation, and subsequent levels of physical activity (PA) and sedentary behaviours (SB). The aim of this study was to review and compare the changes in all reported PA and SB behaviours during versus before the COVID-19 pandemic lockdown, stratifying between adults and children, and special populations. This study is a systemic review of 66 studies which yielded a total of 86981 participants with an age range between 13 and 86 years. Results demonstrated that the majority of studies found that PA declined and SB increased during the COVID-19 pandemic lockdown, regardless of the subpopulation. In healthy adults and children, PA during lockdown decreased compared with pre-lockdown, despite various government organisations and health or exercise practitioners providing guidance on how to stay active during the pandemic and in self-quarantine. Authors conclude that the public health officials should promote ways of increasing PA and reducing SB should further lockdowns occur, especially in populations with medical conditions that are improved by PA.
Abstract
OBJECTIVE In March 2020, several countries banned unnecessary outdoor activities during COVID-19, commonly called 'lockdowns. These lockdowns have the potential to impact associated levels of physical activity and sedentary behaviour. Given the numerous health outcomes associated with physical activity and sedentary behaviour, the aim of this review was to summarise literature that investigated differences in physical activity and sedentary behaviour before vs during the COVID-19 lockdown. DESIGN DATA SOURCES AND ELIGIBILITY CRITERIA Electronic databases were searched from November 2019 to October 2020 using terms and synonyms relating to physical activity, sedentary behaviour and COVID-19. The coprimary outcomes were changes in physical activity and/or sedentary behaviour captured via device-based measures or self-report tools. Risk of bias was measured using the Newcastle-Ottawa Scale. RESULTS Sixty six articles met the inclusion criteria and were included in the review (total n=86 981). Changes in physical activity were reported in 64 studies, with the majority of studies reporting decreases in physical activity and increases in sedentary behaviours during their respective lockdowns across several populations, including children and patients with a variety of medical conditions. CONCLUSION Given the numerous physical and mental benefits of increased physical activity and decreased sedentary behaviour, public health strategies should include the creation and implementation of interventions that promote safe physical activity and reduce sedentary behaviour should other lockdowns occur.

Selecting foods for a day is easily influenced by the social environment and eating together or alone plays a big role in that decision. The study aims to evaluate the association between diet quality of the modern Korean adult population based on the eating behaviour and the socioeconomic factors that influence their diet quality. The study is a cross-sectional study which included 3365 men and 5258 women aged between 19 and 64 years. The study included demographic, socioeconomics, and health behaviour factors as covariates. Results indicate that diet quality is influence by eating behaviour. Authors observed that when Korean adults ate without a companion, their diet quality was significantly lower than those who consistently ate with others. Furthermore, from the higher education to lower education level, the diet quality declined when they eat alone. Authors conclude that many Korean adults are experiencing low diet quality when they eat alone. The study provides evidence to promote interventions to improve diet quality among the public.
Abstract
BACKGROUND To discover the association between eating alone and diet quality among Korean adults who eat alone measured by the mean adequacy ratio (MAR), METHODS The cross-sectional study in diet quality which was measured by nutrient intakes, indicated as MAR and nutrient adequacy ratio (NAR) with the Korean National Health and Nutrition Examination Survey (KNHANES) VI 2013-2015 data. Study population was 8523 Korean adults. Multiple linear regression was performed to identify the association between eating behaviour and MAR and further study analysed how socioeconomic factors influence the diet quality of those who eat alone. RESULTS We found that the diet quality of people who eat alone was lower than that of people who eat together in both male (β: - 0.110, p = 0.002) and female participants (β: - 0.069, p = 0.005). Among who eats alone, the socioeconomic factors that negatively influenced MAR with the living arrangement, education level, income levels, and various occupation classifications. CONCLUSIONS People who eat alone have nutrition intake below the recommended amount. This could lead to serious health problems not only to those who are socially disadvantaged but also those who are in a higher social stratum. Policy-makers should develop strategies to enhance diet quality to prevent potential risk factors.
