Due to the outbreak of coronavirus disease 2019 (COVID-19), the Chinese government implemented strict lockdown measures to control the spread of infection. The impact of the COVID-19 lockdown on eating habits and lifestyles in the general population is unclear. This cross-sectional study was conducted via an online survey to obtain an overview of the food access, food intake, and physical activity of Chinese residents during the initial stage of the COVID-19 lockdown, and to investigate the association between staying at home/working from home and changes in eating habits and lifestyles. A total of 2702 participants (70.7% women) were included. Most of the participants maintained their habitual diet, while 38.2% increased their snack intake, 54.3% reported reduced physical activity, and 45.5% had increased sleep duration. Most people (70.1%) reported no change in body weight, while 25.0% reported an increase. Always staying at home/working from home was associated with an increase in animal product, vegetable, fruit, mushroom, nut, water, and snack intake, as well as sleep duration and frequency of skipping breakfast (odds ratio (OR) 1.54, 1.62, 1.58, 1.53, 1.57, 1.52, 1.77, 2.29, and 1.76 respectively). Suggestions should be made to encourage people to reduce their snack intake, maintain the daily consumption of breakfast, and increase physical activity during future lockdown periods.

From a survey of public participation in a sharing economy, the authors extracted from the factor analysis on a questionnaire three factors: particularised trust, generalised trust and institutional trust. The authors also classified three categories of sharing economy and utilised a structural equation model to study the impact of trust on public participation in the different types. The general observation made is that trust helps to increase public desire to participate in a sharing economy. Compared with participants in a narrow sharing economy, particularised trust and generalised trust increased the public desire to participate in a generalised sharing economy. In contrast to participating in the low trust-based demand-side (LTBD) sharing economy, particularised trust and generalised trust promote greater public participation in the high trust-based demand-side (HTBD) sharing economy. It is also noteworthy that institutional trust has a positive impact on a low trust-based demand-side sharing economy. Based on the findings, two policy recommendations are offered. (China/GIGA)
