Changes in Adults' Eating Behaviors During the Initial Months of the COVID-19 Pandemic: A Narrative Review

Factors such as regulations and health concerns shifted daily habits, including eating behaviors, during the early months of the coronavirus disease 2019 (COVID-19) pandemic. This comprehensive narrative review synthesizes research on eating behavior changes during the early months of the pandemic (February to June 2020), including changes in amount, rate, and timing of food consumption, types and healthfulness of foods consumed, the occurrence of other specified eating behaviors (eg, restrained eating or binging), and reasons for eating (eg, stress or cravings), among adults. A literature search using three EBSCOhost databases and Google Scholar was conducted to identify relevant articles made available in 2020. A total of 71 articles representing 250,715 individuals from more than 30 countries were reviewed. Findings show eating behaviors changed little during the early COVID-19 pandemic for most participants. Among those whose eating behaviors changed, increases in both intake and frequency of eating meals and snacks were more common than decreases. Findings on timing of eating and healthfulness of food consumed showed mixed results. However, when changes occurred in the type of food consumed, increases were more common for snacks, homemade pastries, white bread/pasta, legumes, and fruits/vegetables; decreases were more common for meats, seafood/fish, frozen foods, fast food, dark breads/grains, and dark leafy green vegetables. During the pandemic, binging, uncontrolled eating, and overeating increased, meal skipping decreased, and restrictive eating had mixed findings. Changes in factors such as emotions and mood (eg, depression), cravings, and environmental factors (eg, food insecurity) were related to changes in eating behaviors. Findings can inform clinical practitioners in efforts to mitigate disruptions to normal, healthy eating patterns among adults both in and outside of global health catastrophes.

Health impacts of bike-sharing systems in the U.S

BACKGROUND

Bike-sharing systems (BSS) are short-term bike rentals that can be borrowed from one location and retired to another at the conclusion of the trip. In 2019, 109,589 BSS trips were made each day in the U.S, and half of those in New York City (NYC).

AIM

This study aims to quantify the health risks and benefits of BSS in the U.S. and NYC.

METHODS

This study followed a quantitative health impact assessment approach to estimate the risks and benefits of BSS. Specifically, we quantified the health impacts of physical activity, air pollution, and traffic incidents. We analyzed all the trips made by BSS in the U.S. and NYC. Input data on transport, traffic safety, air quality, and physical activity were collated from public records and scientific publications. We modeled the health impacts on adult users related to mortality, disease incidence, disability-adjusted life years (DALYs), and health economic impacts (related to morbidity and mortality).

RESULTS

We estimated that in the U.S. BSS trips resulted in an annual reduction of 4.7 premature deaths, 737 DALYs, and 36 million $USD in health economic impacts, mainly derived from the increment in physical activity. In NYC, we estimated an annual reduction of 2 premature deaths, 355 DALYs, and 15 million $USD in health economic impacts.

CONCLUSION

BSS in the U.S. and NYC provide a health benefit for bicyclists. Improvements in air quality and traffic safety across U.S. cities will maximize the health benefits of BSS.
